TOOL
Filed Dec. 12. 1966 I8 48 ATTORNEYS United States Patent TOOL Ernst Willy Flegel, 11 Grenzstrasse, 611 Dieburg, Germany Filed Dec. 12, 1966, Ser. No. 600,954 7 Claims. (Cl. 29e-233) ABSTRACT F THE DISCLOSURE A pair of these t-ools are placed against the jaws of a vice to grip a shaft between them and operate, as the vice is tightened, to force the shaft axially into or out of some member such as la bearing or housing which tightly fits the shaft. The bearing or housing must be held stationary during the process.
Brief summary of the invention Each tool includes a pair of spaced blocks movably `held lby a housing and a cam plate or force-transmitting member extends between the blocks. Resilient means such as rubber blocks or springs serve to normally separate the blocks and the engagement of the force-transmitting member with the two blocks is such as to cause relative parallel movement between them whenever they are squeezed together.
In the drawing:
FIGURE 1 is a view illustrating the invention in operation and showing two of the tools of the invention in cross-section;
FIGURE 2 is an enlarged side elevational view partly in section showing ldetails `of a tool according to the present invention;
FIGURE 3 is a plan view of the tool shown in FIG- URE 2;
FIGURE 4 is a tranverse section taken substantially along the plane of section line 4 4 in FIGURE 2 show- -ing further details of the tool; and
FIGURE 5 is a View similar to FIGURE 4 but showing a modified form of construction.
Referring at this time more particularly to FIGURE 4, the tool according to the present invention consists of a pair of blocks and '12 contained within a housing 14 and separated therein by a pair of resilient blocks 16 and 18. Each block 19 and 12 is provided with an outer face 20- which is preferably provided with grooves, striations or the like las indicated by the reference character 22 so as to provide a good gripping surface. Additionally, each block is provided with an inner face 24 and the resilient blocks 16 and 18 serve to normally space these inner faces as shown to accommodate for the intervening force`transmitting member 26.
The exact geometrical configuration of the tool in side elevation is immaterial. However, the preferred side elevational shape ofthe blocks 10 and 12 is as can be seen from FIGURE 2, generally rectangular with semi-circular ends. The housing 14 is also of this ygeneral configuration and as can be seen from FIGURES 2, 3 and 4, the opposite side edges of the housing 14 are curved inwardly to leave the somewhat restricted openings 27 through which the outer sides Iof the two blocks 10 and 12 project. The inturned edges of the housing form seats against which the circular cross-sectional resilient beads 28 seat. these beads being also seated in circumferentially extending grooves in the blocks 10 and 12, see particularly FIG- URE 4. The resilient members 16 and 18 previously described are preferably of rectangular configuration as can be seen best in FIGURES 2 and 3 and these members 16 and 18 are sandwiched between the top and bottom walls of the housing 14 and themselves sandwich the forcetransmitting member 26 therebetween. The housing 14 is 3,384,948 Patented May 28, 1968 VCC l preferably formed of sheet metal and is of light enough gauge so I'as to be deformable during use as will hereinafter appear and its inherent resiliency, tending to return it to the normally relaxed posit-ion shown in FIGURE 4 together with the similar action of members 16 and 18 will normally retain the various parts positioned as is shown in FIGURE 4. The inner sides 24 of the blocks 10 and 12 are provided with troughs or grooves 30 and it will be seen that the opposite side edges of the forcetransmitting member 26 are lbevelled oppositely and rounded as indicated by the reference character 32 so as to seat and pivotally contact within the respective grooves 30. At the same time, it will be appreciated that the grooves 30 and the opposite side edges 32 of the forcetransmitting member 26 establish, in the normally relaxed position of the tool, a relationship wherein the lines of contact between the respective side edges of the force-transmitting member 26 and the inner sides of the blocks 10 and 12 are vertically staggered so that a plane containing these two `lines of contact extends between the planes containing the two outer faces 20 but at an oblique angle thereto. Thus, when a pair of these tool members are used on opposite sides of a workpiece such as a shaft 34 as shown in FIGURE l, and caused to be forced against the shaft and grip same therebetween, the vertically staggered relationship between the aforementioned lines of contact will cause axial movement of the shaft 34 as indicated by arrow 36 in FIGURE l. Thus, the tools will simultaneously grip and axially move the shaft or workpiece. If the shaft is to be extracted or inserted into a member such as the ball bearing 38 in FIGURE l, it becomes simply a matter of holding the b'all bearing or other member in fixed relation relative to the movement of the shaft imparted by the tools. In FIGURE 1, this is accomplished by butting the 'bearing against the underside of the vice shown in dash-dash lines. FIGURE 1 also ilustrates that as the tools are forced against the workpiece, the movement imparted to the workpiece takes place by virtue of relative vertical movement between the blocks 10 and I12, the housing 14 accommodating for this movement by distortion as shown. To force the workpiece 34 in the opposite direction, it would of course be necessary to reverse the tools.
In the modification shown in FIGURE 5, the principles remain the same as -set forth hereinabove, but in this particular case, two force-transmitting members 40 and 42 are utilized and of course, this necessitates the utilization of three resilient members 44, 46 and 48. In all other respects, the construction is in principle the same as set forth hereinbefore.
I claim:
1. A tool adapted to be forcefully engaged against a workpiece for moving the workpiece in a direction normal to the direction of engagement, comprising,
a pair of blocks, each block having an inner side face and an outer side face,
means for resiliently holding said blocks in spaced relation with respect to each other with said outer side faces disposed in parallel relation and said inner side faces in opposed spaced relation, and
a force-transmitting member extending between said inner side faces and pivotally contacting the same, the pivotal contacts between said force-transmitting member and the respective inner side faces of said blocks lying in a plane which is oblique to the planes containing said outer side faces.
2. The tool as defined in claim 1 wherein said means comprises a housing surrounding said blocks and a pair of resilient members interposed between said blocks and held captive by said housing.
3. The tool as defined in claim 2 wherein said resilient members are blocks of rubber-like material.
4. The tool as defined in claim 2 wherein said forcetransmitting member comprises a plate having oppositely bevelled side edges contacting said blocks.
5. The tool as defined in claim 2 wherein said forcetransmitting member comprises a pair of parallel, spaced plates, each having oppositely bevelled side edges contacting `said blocks.
6. The tool as defined in claim 1 wherein said forcetransmitting member comprises a plate having oppositely bevelled side edges contacting said blocks.
7. The tool as defined in claim 1 wherein said forcetransmitting member comprises a pair of parallel, spaced plates, each having oppositely bevelled side edges coiitacting said blocks.
