Definitions
- Crimping or pressing tools are well known in the art and are used for many purposes.
- One of the best known uses is as a device for mechanically securing a fastener to an electrical wire or cable.
- one end of the fastener is in the form of a cylindrical, hollow sleeve, and the other end is an eyelet, pin or socket or similar fastener element.
- the sleeve is adapted for receiving an end of the wire or cable and is clamped thereon by deforming the sleeve through use of a crimping tool.
- crimping tools Another use for crimping tools involves clamping metal rings onto tubing or other fittings.
- An example of tools for this application is a tool for crimping metal fittings on cross-linked polyethylene (PEX) tubing. These tools are adapted for making PEX tubing connections such as used in porrtable water and radiant heating applications. Such tools have also been used in association with the commercially available ProPressTM copper systems with transitions to PEX systems.
- PEX polyethylene
- Crimping tools may generally be characterized as being either of two types: circumferential or tangential.
- a circumferential crimp tool typically has a set of jaws configured to provide a pair of crimping surfaces or crimp nest which is at least generally symmetric, for example circular, square, hexagonal, etc.
- ASTM F 1807 herein incorporated by reference, provides standards for systems of metal insert fittings utilizing a circumferential type crimp ring element for PEX tubing. Examples of circumferential crimping tools are described in U.S. Pat. Nos. 5,722,284 to Linsmeyer and 6,164,106 to Nghiem.
- Tangential-type crimping tools are characterized as having a pair of projections or pincers that generally face one another. When using such tools, the pincers are positioned about an outwardly projecting portion or shoulders of a crimp element.
- ASTM F 2098 herein incorporated by reference, provides standards for systems of tangential type clamps for securing PEX tubing to metal insert fittings.
- An example of a tangential-type crimping tool is shown in U.S. Pat. No. 4,724,729 to Oetiker.
- crimping tools that can accommodate a range of different sized crimping elements.
- such tools have only accommodated a limited range of sizes of crimping elements of a particular type, i.e. circumferential or tangential.
- Certain powered tools such as pressing tools, use a powered hand unit and multiple, selectively engageable jaws or jaw sets.
- Jaw sets are known that include circumferential crimping configurations.
- Other jaw sets are also known for tangential crimping applications.
- a problem with these tool systems is that the manufacturing process to produce the jaw can be costly.
- the cost of tools to cover a range of crimping sizes and applications increases as well as the inconvenience of having to bring all tools and jaws to the job site. Accordingly, it would be desirable to provide a powered tool and jaw set combination that could be used for both circumferential and tangential type applications.
- Crimping or pressing tools that employ various jaw inserts to accommodate a range of crimping application sizes are known.
- U.S. Pat. No. 6,772,618 to Frenken shows a pressing tool having removable jaw inserts.
- the insert allows the operator to use a single jaw set as a carrier for a single insert that can be selected from a set of such inserts.
- the inserts may vary with respect to size, profile or application. Additionally the inserts are significantly lighter, smaller and less expensive to produce than corresponding jaws. Examples of various known tool designs using inserts include U.S. Pat. Nos. 3,706,219 to Hoffman et al; 4,576,067 to Buck; 5,113,727 to Foster; and 7,188,508 to Hamm et al.
- this configuration still does not provide a single assembly that can be used for both circumferential and tangential type applications. That is, in order to use such a jaw set and insert assembly, for crimping tangential elements and then for circumferential elements for example, an operator must provide and transport one or more tools for the tangential crimping application and one or more tools for the circumferential crimping application. After crimping the tangential elements, the insert and possibly the jaw set, must be replaced with those adapted for crimping circumferential elements. Accordingly, a need remains for a single tool and jaw insert system that can accommodate both types of applications.

- FIG. 10 illustrates a preferred embodiment gauge 600 in accordance with the present invention.
- the gauge 600 provides dimensional indicators for estimating or determining a range of sizes for circumferential crimping applications and tangential crimping applications.
- the gauge 600 can be in the form of a “Go-No-Go” gauge as that term is understood by those skilled in the art.
- the gauge 600 serves as an inspection tool to check the extent of crimping or compression applied to a workpiece.
- the gauge 600 is a measuring tool that does not necessarily return a size in the literal sense, but instead returns a state.
- the gauge 600 provides a series of circumferential, i.e.
- each dimensional indicator is provided along the periphery of the gauge 600 .
- the “Go-No-Go” aspect of the gauge 600 can be used to determine whether a circumferential crimped element has been sufficiently compressed about an underlying member. If, after crimping, the crimped element has an outer diameter small enough to fit within the Go indicator and has an outer diameter that is too large to fit within the corresponding No-Go indicator, then the element has been sufficiently compressed.
- the gauge is preferably formed from a relatively flat and thin sheet of a durable material such as metal or certain plastics.
- the circumferential indicators of the gauge 600 are preferably slotted openings having a span or access width that corresponds to the desired range of diameters of the circumferential crimping element after crimping. That is, the preferred embodiment gauge defines a collection of openings, each of which corresponds to a minimum and maximum desired diameter of a circumferential crimping element after crimping. It is also preferred that the interior portion of each opening define an arcuate edge, and preferably, a semi-circular edge, having a diameter equal or substantially so, to the access width of the respective opening.
- the circumferential indicator 610 defines an arcuate edge 612 that preferably extends through an arc of 1800 between a pair of side edges 614 and 616 . The side edges are parallel to one another and spaced apart a distance corresponding to the desired diameter indicative of the indicator 610 .
- the tangential indicators of the gauge 600 are also preferably slotted openings.
- the span or width of each opening corresponds to the preferred maximum width of a tangential crimping element after crimping. This width, as will be appreciated by those skilled in the art, is the distance between the shoulders of the crimping element in its post-crimp state. It is frequently desirable, and often necessary, to utilize a tangential indicator to determine whether sufficient crimping has occurred.
- the gap between the shoulders of a crimped tangential type element may increase or “spring back” due to resiliency or elastic memory of the crimp element.

Abstract
A manual or powered crimping tool, and corresponding jaw set, are described that include a combination of provisions for crimping tangential type crimping elements and one or more circumferential type crimping elements. Various versions of the tool and jaw set are provided including tools and jaw sets that include provisions for using a selectively replaceable insert that significantly increases the range of applications of the tool or jaw set. Tool versions are also provided having insert receiving surfaces, such as when used with inserts, that also serve as crimping surfaces.
Description
- Crimping or pressing tools are well known in the art and are used for many purposes. One of the best known uses is as a device for mechanically securing a fastener to an electrical wire or cable. Typically, one end of the fastener is in the form of a cylindrical, hollow sleeve, and the other end is an eyelet, pin or socket or similar fastener element. The sleeve is adapted for receiving an end of the wire or cable and is clamped thereon by deforming the sleeve through use of a crimping tool.
- Another use for crimping tools involves clamping metal rings onto tubing or other fittings. An example of tools for this application is a tool for crimping metal fittings on cross-linked polyethylene (PEX) tubing. These tools are adapted for making PEX tubing connections such as used in porrtable water and radiant heating applications. Such tools have also been used in association with the commercially available ProPress™ copper systems with transitions to PEX systems.
- Crimping tools may generally be characterized as being either of two types: circumferential or tangential.
- A circumferential crimp tool typically has a set of jaws configured to provide a pair of crimping surfaces or crimp nest which is at least generally symmetric, for example circular, square, hexagonal, etc. ASTM F 1807, herein incorporated by reference, provides standards for systems of metal insert fittings utilizing a circumferential type crimp ring element for PEX tubing. Examples of circumferential crimping tools are described in U.S. Pat. Nos. 5,722,284 to Linsmeyer and 6,164,106 to Nghiem.
- Tangential-type crimping tools are characterized as having a pair of projections or pincers that generally face one another. When using such tools, the pincers are positioned about an outwardly projecting portion or shoulders of a crimp element. ASTM F 2098, herein incorporated by reference, provides standards for systems of tangential type clamps for securing PEX tubing to metal insert fittings. An example of a tangential-type crimping tool is shown in U.S. Pat. No. 4,724,729 to Oetiker.
- When using crimping tools, it is often necessary to select the tool that is of an appropriate (i) type, i.e. circumferential or tangential, and (ii) size for the particular application. The selection of either a circumferential or tangential configuration is determined by the particular application and in some instances, by the preference of the user. The selection of an appropriate size tool is governed by the particular application which in turn dictates the size of the crimping elements. Since applications can dictate a wide range of different sizes of crimping elements, and since it is difficult if not impossible to use a single crimp tool for all crimping elements, manufacturers typically provide different sized tools.
- Using multiple crimping tools in the field and transporting the tools to and from the work site can be cumbersome and is generally undesirable. In order to at least reduce the number of crimping tools that may be required, manufacturers have provided crimping tools that can accommodate a range of different sized crimping elements. However, as far as is known, such tools have only accommodated a limited range of sizes of crimping elements of a particular type, i.e. circumferential or tangential. Thus, if applications exist for both types of crimping elements, i.e. circumferential and tangential, it is necessary to provide and use two separate tools or sets of tools. Accordingly, it would be desirable to provide a single tool that could be used with crimping elements of not only a variety of sizes, but also with different types such as circumferential or tangential crimping elements. Furthermore, it would also be desirable to provide a tool that could be used with a wide range, or multiple ranges, of sizes of crimping elements. Providing such a tool would reduce the overall quantity of crimping tools that an operator might otherwise require, which would be particularly desirable when performing crimping applications in the field.
- Certain powered tools such as pressing tools, use a powered hand unit and multiple, selectively engageable jaws or jaw sets. Jaw sets are known that include circumferential crimping configurations. Other jaw sets are also known for tangential crimping applications. A problem with these tool systems, is that the manufacturing process to produce the jaw can be costly. Also, since each different size fitting generally requires its own jaw or jaw set, the cost of tools to cover a range of crimping sizes and applications increases as well as the inconvenience of having to bring all tools and jaws to the job site. Accordingly, it would be desirable to provide a powered tool and jaw set combination that could be used for both circumferential and tangential type applications.
- Crimping or pressing tools that employ various jaw inserts to accommodate a range of crimping application sizes are known. For example, U.S. Pat. No. 6,772,618 to Frenken shows a pressing tool having removable jaw inserts. The insert allows the operator to use a single jaw set as a carrier for a single insert that can be selected from a set of such inserts. The inserts may vary with respect to size, profile or application. Additionally the inserts are significantly lighter, smaller and less expensive to produce than corresponding jaws. Examples of various known tool designs using inserts include U.S. Pat. Nos. 3,706,219 to Hoffman et al; 4,576,067 to Buck; 5,113,727 to Foster; and 7,188,508 to Hamm et al. Although generally satisfactory, this configuration still does not provide a single assembly that can be used for both circumferential and tangential type applications. That is, in order to use such a jaw set and insert assembly, for crimping tangential elements and then for circumferential elements for example, an operator must provide and transport one or more tools for the tangential crimping application and one or more tools for the circumferential crimping application. After crimping the tangential elements, the insert and possibly the jaw set, must be replaced with those adapted for crimping circumferential elements. Accordingly, a need remains for a single tool and jaw insert system that can accommodate both types of applications.
- The present invention achieves all of the foregoing noted objectives. In one aspect, the present invention provides a jaw set adapted for crimping a deformable crimp element about a member. The jaw set comprises a first jaw defining a front portion and an oppositely directed rear portion with the inner and outer edges extending between the front and rear portions. The jaw set also comprises a second jaw defining a front portion and an oppositely directed rear portion, and inner and outer edges extending between the front and rear portions of the second jaw. Each of the first and second jaws include an outwardly extending pincer portion near the front portion and along the inner edge of the respective jaw. Each of the first and second jaws also defines a recessed arcuate surface that is accessible along the inner edge of the respective jaw. The first and second jaws are positioned and operatively coupled to one another such that the pincer portions of the first and second jaws are opposite one another and define a tangential crimping configuration, and the recessed arcuate surfaces of the first and second jaws are also opposite one another and provide a circumferential crimping configuration.
- In another aspect, the present invention provides a jaw set adapted for crimping a deformable crimp element about a member. The jaw set comprises a first jaw defining a front portion and an oppositely directed rear portion. The first jaw also defines inner and outer edges extending between the front and rear portions. The jaw set also comprises a second jaw defining a front portion and an oppositely directed rear portion, and inner and outer edges extending between the front and rear portions of the second jaw. Each of the first jaw and the second jaw defines a recessed arcuate surface accessible along the inner edge of the respective jaw. Each recessed surface extends between the front portion and an interior portion disposed between the front and rear portion of each jaw. Each of the first jaw and the second jaw also include an outwardly extending pincer portion proximate the interior portion of the respective jaw. The first and second jaws are positioned and operatively coupled to one another such that the pincer portions of the first and second jaws are opposite one another and define and interiorly disposed tangential crimping configuration and the recessed arcuate surfaces of the first and second jaws are also opposite one another and provide a circumferential crimping configuration.
- In yet another aspect, the present invention provides a gauge adapted for determining a collection of sizes for circumferential crimping applications and tangential crimping applications. The gauge comprises a relatively flat planar member defining a first face, a second oppositely directed face, and a peripheral edge separating the first and second faces. The member further defines (i) a first set of slotted openings each having a span corresponding to a desired minimum diameter of a circumferential crimping element after crimping, (ii) a second set of slotted openings each having a span corresponding to a maximum desired diameter of a circumferential crimping element after crimping, and (iii) a third set of slotted openings, each having a span corresponding to the width of a tangential crimping element after crimping.
- In addition to the specific aspects provided by the present invention, the invention also relates to and provides a multi-system tool or jaw set embodied in a single device or assembly. As explained in detail herein, a single tool or jaw set is provided that can be used with multiple systems such as one or more circumferential systems and one or more tangential systems; one circumferential system and another circumferential system; and two or more circumferential systems and a tangential system for example.
- The present invention also relates to and provides a tool or jaw set specifically having circumferential crimping or pressing provisions in combination with tangential crimping or pressing provisions.
- The present invention also relates to and provides one or more inserts and combination of such inserts in conjunction with a tool or jaw set as described herein, which can be used for a wide array of crimping or pressing applications. The provision of inserts further expands the application, use, and convenience of the present invention tools, jaw sets, and systems thereof.
- The present invention also relates to and provides specific types of jaw sets, pressing rings, pressing assemblies, and like tools for performing radial pressing operations.
- The present invention also relates to and provides tools and jaw sets employing one or more specific crimping profiles or contours as known in the art. Multiple crimping profiles such as certain commercially known circumferential crimping contours may be provided for the tools, jaw sets, inserts, and systems described herein.
- The present invention also relates to and provides inserts and tools and jaw sets using such inserts, having tangential crimping provisions incorporated into one or more inserts.
- The present invention also relates to and provides systems of multiple inserts in which one insert is used or engaged with, i.e. nested within, another insert, that in turn is used in conjunction with the tools and jaw sets described herein.
- These and other features and aspects of the present invention are described herein.

FIG. 9 is a perspective view of the jaw set 400 depicted inFIG. 8 , engaged with a poweredpressing tool 500. Thetool 500 comprises ahousing 510, ahandle 520, abattery pack 530, aforward end 540, and an oppositely directedrear end 550. Thebattery pack 530 preferably is selectively engageable along the distal lowermost end of thehandle 520. Thetool 500 includes atrigger 525 that upon actuation, initiates activation of thetool 500. Projecting from the front face of theforward end 540 is a receivingassembly 545 that is adapted to selectively engage a jaw set such as jaw sets 300 or 400, depicted inFIGS. 7 and 8 respectively. - Disposed within the interior of the

FIG. 10 illustrates apreferred embodiment gauge 600 in accordance with the present invention. Thegauge 600 provides dimensional indicators for estimating or determining a range of sizes for circumferential crimping applications and tangential crimping applications. Preferably, and as depicted, thegauge 600 can be in the form of a “Go-No-Go” gauge as that term is understood by those skilled in the art. Thegauge 600 serves as an inspection tool to check the extent of crimping or compression applied to a workpiece. Thegauge 600 is a measuring tool that does not necessarily return a size in the literal sense, but instead returns a state. Specifically, thegauge 600 provides a series of circumferential, i.e. according to ASTM F1807, indicators such as 610, 620, 630, 640, 650, and 660. Thegauge 600 also provides a series of tangential indicators such as 670, 680, and 690. As will be appreciated, each dimensional indicator is provided along the periphery of thegauge 600. The “Go-No-Go” aspect of thegauge 600 can be used to determine whether a circumferential crimped element has been sufficiently compressed about an underlying member. If, after crimping, the crimped element has an outer diameter small enough to fit within the Go indicator and has an outer diameter that is too large to fit within the corresponding No-Go indicator, then the element has been sufficiently compressed. If however, the crimped element fits in both of the Go and No-Go indicators, then the element has been excessively or overly crimped. If instead, the crimped element does not fit within the Go indicator, then the element has not been sufficiently crimped. The gauge is preferably formed from a relatively flat and thin sheet of a durable material such as metal or certain plastics. - The circumferential indicators of the
gauge 600 are preferably slotted openings having a span or access width that corresponds to the desired range of diameters of the circumferential crimping element after crimping. That is, the preferred embodiment gauge defines a collection of openings, each of which corresponds to a minimum and maximum desired diameter of a circumferential crimping element after crimping. It is also preferred that the interior portion of each opening define an arcuate edge, and preferably, a semi-circular edge, having a diameter equal or substantially so, to the access width of the respective opening. Thus, for example, thecircumferential indicator 610 defines anarcuate edge 612 that preferably extends through an arc of 1800 between a pair of side edges 614 and 616. The side edges are parallel to one another and spaced apart a distance corresponding to the desired diameter indicative of theindicator 610. - The tangential indicators of the
gauge 600 are also preferably slotted openings. The span or width of each opening corresponds to the preferred maximum width of a tangential crimping element after crimping. This width, as will be appreciated by those skilled in the art, is the distance between the shoulders of the crimping element in its post-crimp state. It is frequently desirable, and often necessary, to utilize a tangential indicator to determine whether sufficient crimping has occurred. Depending upon the material of the crimp element and/or its physical characteristics, and also the characteristics of any underlying workpiece, after crimping, the gap between the shoulders of a crimped tangential type element may increase or “spring back” due to resiliency or elastic memory of the crimp element. Thus, it is beneficial to use a tangential crimp indicator to confirm that sufficient crimping has occurred. Inherently, it is likely that spring back occurs. The degree of spring back typically varies depending upon fitting size. This is the reason that thepreferred embodiment gauge 600 provides indications for multiple sizes. - The present invention also provides a jaw configuration, a jaw set using such configuration, one or more jaw inserts, and a system of these features adapted for use with a manual or powered tool or tool assembly. Specifically, in this aspect, the invention provides a jaw configuration for a tool, manual or powered, which can be used for crimping or pressing applications, and which can be used in conjunction with one or more inserts.
- More specifically, the present invention provides a wide variety of different style and different size inserts for use in conjunction with a jaw set as described herein. For example, in this aspect of the invention, a jaw set is provided that defines an insert receiving surface which in turn, receives an insert member that can be used to crimp a crimp element. The jaw set can be used to crimp a range of different sized crimp elements by appropriate selection of an insert of a size corresponding to the element to be crimped. In addition to the inserts varying from one another in size, the inserts may also vary from one another in one or more other characteristics such as, but not limited to crimp shape. Furthermore, in accordance with the present invention, jaw sets and/or inserts can be provided to accommodate multiple types or combinations of circumferential crimping systems.

FIGS. 11 to 15 illustrate a preferred embodiment jaw and an insert member in accordance with the present invention. Although the jaw depicted in these figures is of the type adapted for use in a powered tool, it will be appreciated that the following description is equally applicable to a manually powered tool. Specifically,FIGS. 11 and 12 illustrate apreferred embodiment jaw 700 comprising ajaw body 710, anose 720, anoppositely extending arm 730, and a recessedinsert receiving region 740. Thejaw 700 defines first and second oppositely directed lateral faces 702 and 704, anouter edge 706, and aninner edge 708, both edges extending about opposite peripheral regions of thejaw 700. Thejaw 700 preferably defines anaperture 750 for receiving an engagement member, such as for coupling an alignment member (not shown) thereto. Thejaw 700 can also define a rearwardly disposed and preferably recessedregion 760 that can carry logo(s) or other markings as desired. - The
insert receiving region 740 is preferably defined by a concave, recessed,arcuate surface 742 that extends along theinner edge 708 of thejaw 700. Defined along one or both of lateral faces 702 and 704 of thejaw 700 are a plurality ofretention members retention members surface 742 of theinsert receiving region 740. Although the invention includes a wide array of designs and configurations for the retention members, a preferred configuration is that each member be in the form of an outwardly extending member. In certain instances, the retention members can be in the form of spring loaded or otherwise outwardly biased displaceable members that are received by or otherwise engaged with corresponding apertures or recesses in the insert. The insert can be retained to its corresponding jaw in nearly any fashion. For example, the present invention includes the use of magnetic retention strategies and the use of straps formed from elastomeric materials or metals that extend about the insert and outer surface of the jaw. A wide array of other retention strategies are contemplated and included in the present invention such as the use of selectively releasable pins or threaded connectors that temporarily affix an insert to the jaw. Thesurface 742, if used in conjunction with an insert as previously described, would then correspond to an insert receiving surface as that term is used herein. However, thesurface 742 could also serve as a crimping surface. -
FIGS. 13 and 14 illustrate a preferredembodiment insert member 800 in accordance with the present invention. Theinsert member 800 is preferably in the shape of a semicircle and includes a pair oflateral side walls arcuate member 830 extending between thewalls member 830 defines two oppositely directed surfaces, aconvex mating surface 840 and an oppositely directed concave crimping or workingsurface 850. Each of thesidewalls insert 800 includes a plurality of receiving apertures or slots that engage theretention members jaw 700 shown inFIG. 11 once theinsert 800 is appropriately positioned in theinsert receiving region 740 of thejaw 700. Specifically in this regard, thesidewall 810 definesapertures sidewall 820 definesapertures - The various inserts described herein feature outer surfaces for engagement and contact with jaws described herein. That is, the inserts feature an outer or backside surface configured to contact and preferably seat against a corresponding insert receiving surface defined in the jaw member. The inserts also feature an oppositely directed surface referred to herein as a crimping surface as such surface contacts a workpiece or crimp element for subsequent crimping. Referring to
FIGS. 11-15 again, upon placement ofinsert member 800 in thejaw 700, theconvex mating surface 840 of theinsert 800 contacts and is engaged alongside theinsert receiving region 740, and specifically the insert receiving surface defined therein of thejaw 700. Upon use of thejaw 700 and theinsert 800, the crimpingsurface 850 of the insert contacts the workpiece or crimp element. -
FIG. 15 is a perspective view of an assembly of thepreferred embodiment jaw 700 and the preferredembodiment insert member 800 engaged therewith. - It will be appreciated that in using the jaw and insert assembly, two of the assemblies are used to provide a jaw set. And two or more inserts or insert members are utilized in a typical crimping application.
- A jaw or jaw set and an insert member may be provided or implemented in combination with the dual crimping system described herein. That is, the present invention also provides a jaw set, adapted for use with a manual or powered tool or tool assembly, that includes jaw provisions for receiving insert members in combination with one or more tangential and/or circumferential crimping provisions. For example, the present invention includes a jaw set comprising provisions for receiving insert members in combination with a pair of tangential pincing portions. The invention also includes a jaw set comprising provisions for receiving insert members in combination with one or more circumferential crimping surfaces. The present invention also includes a jaw set having a combination of provisions for receiving insert members, a pair of tangential pincing portions, and circumferential crimping surfaces. In addition, the present invention includes a jaw set having multiple provisions for receiving insert members, such as a first set of insert members and a second set of insert members. The two or more different sets of insert members can vary by size, shape or configuration. It is also contemplated, to provide a jaw set that includes multiple provisions for receiving two or more sets of insert members in combination with a pair of tangential pincing portions, and/or one or more circumferential crimping surfaces. And, as previously noted, the jaw sets can be configured to accommodate multiple types or combinations of different types of circumferential crimping systems.

Thejaw assembly 1000 and thejaw assembly 1100 can each be used in a jaw set to crimp a relatively wide range of different sizes of circumferential type crimping elements. Thejaw assembly 1000 enables circumferential crimping of a wide range of sizes, shapes, and configurations, since inserts of different sizes can be selected and positioned in the receivingsurface 1050. The crimpingsurface 1040 can for example, be of a size that is popular or common. Thejaw assembly 1100 is similar tojaw assembly 1000, however provides two sets of circumferential crimping provisions, i.e. 1140 a and 1140 b. This pair of crimping provisions may be of appropriate sizes to accommodate two common or popular sizes of crimping elements.
