CUTTER ATTACHMENT FOR TOGGLE-ACTUATED PLIER-TYPE WRENCHES Filed April 28, 1947 WNV Y nu JNVENTOR. hris'lan Pe 'ersen Patented Mar. 18, 1952 CUTTER ATTACHMENT FOR '.IOGGLE-y ACTUATED PLIER-TYPE WRENCHES christian Petersen, De Witt, Nebr., a.ssigno i0 Petersen Mfg. Co., Inc., Dewitt, Nebr., a corporation of Nebraska Y Appiieaiion April 2s, 1947, seria1No.744,4o9 i l Claim. l

This invention relates to a Wrench and it is primarily an object of the invention to provide a wrench of a toggle type and wherein is embodied wire cutting means making it possible to cut very heavy Wire ordinarily impossible to sever by a squeezing action.

The invention also has for an object to provide a tool of this kind wherein one of the cutting elements projects beyond the associated working face of a jaw of the wrench.

It is also an object of the invention to provide a tool of thisvkind including relatively movable jawsl one of which carrying an anvil and the other having a cutting edge opposed to the anvil and wherein the anvil is provided with a flat Working surface whereby is eliminated the necessity of keeping the anvil and cutting edge in perfect sidewise alignment in order to effect the cutting of a wire.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved wrench, whereby certain advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proccedto describe the same with reference to the accompanying drawing, wherein;

Figure 1 is a view partly in section and partly in elevation illustrating a tool constructed in accordance with an embodiment of the invention;

Figure 2 is an enlarged detailed sectional view taken substantially on the line 2--2 of Figure 1, a second position of certain of the parts being indicated by broken lines;`

Figure 3 is a view similar to Figure 2 but illustrating another embodiment of the invention; and

Figure 4 is also a view similar to Figure 3 but illustrating a still further embodiment of the invention.

In the embodiment of the invention as illustrated in Figures 1 andl 2, A denotes an elongated handle member of channel formation but having its outer end portion I closed and formed to provide a sleeve 2 through which threads a shank 3. The outer end portion of the shank 3 is provided with a head Il to facilitate rotation of the shank to effect the adjustment desired for a purpose to be later referred to.

The opposite or outer end portion of the handle A is provided with a stationary jaw 5 and nwardly of the jaw 5 and particularly the serrated working jaw face 6 thereof, the handle A is open.

Partially extending within the handle A and partially overlying the inner or adjacent end `portion of the toothed working face 5 of the jaw 5 is an anvil 1 welded as at 8, or otherwise rigidly maintained in position with the outer or extended portion of the anvil 1 in direct contact with the portion of the jaw I2.

working face 6 of the jaw 5. y

The body of this anvil I projects a predeten mined distance beyond the working face 6 of the jaw 5 and has a longitudinally fiat working face 9 directed toward the other jaw, with which is adapted to directly coact the cutting edge of a blade I0 positioned atthe inner portion of the working face of the movable jaw I2.

The blade I0 is oppositely beveled to provide an elongate cutting edge I4, which has cutting coaction with the face 9 of the anvil 1. The face 9 extends on a line oblique to the jaw face 6 while the edge I4 is substantially parallel to the jaw face II, adjacent thereto.

The jaw the handle A. The pivotal mounting includes an inwardly directed wing or flange I5 at the inner lIhe inner end portion of the jaw I2 has pivotally engaged therewith as at I6, asection I'I of an articulated lever L. This lever L comprises two sections I'I and I8-, the second section I3 of which extends within the handle A and has direct contact with the inner or inserted end of the shank 3. The section I'I extends beyond the pivotal connection I9 between the sections I'I and I8 and said extended portion constitutes a hand grasp 2i) whereby `the jaw I2 may be readily moved toward the jaw 5 either vto clamp an article between the Ajaws 5 and I2 or to effect the cutting or severing of a wire.

' It is to be noted that the outer or fiat face 9A of the anvil is disposed at such an angle astofhave the same parallel to the knife or cutting edgeIlI of the blade I0 when the jaw I2 is at substantially the limit of its movement toward the jaw 5.

Engaged with the inner or rear end portion of the jaw I2 as at 2l, is an end portion of a retractile member 22, the opposite end portion of which being anchored or operatively engaged, as at 23, to the handle member A. This retractile member 22 provides means whereby the jaw I2 is automatically moved into open position.

The operation ofthe tool as a wrench is believed to be readily apparent from the foregoing description in connection with the accompanying drawings but it is to be stated that in the cutting of the wire or kindred strands it often occurs I2 has its rear portion pivotally mounted as at a within the forward portionV ofY that such wire or strands are of such gauge whereby it is impossible to eiect the desired severing by a squeezing operation. However, with the tool as herein embodied, the cut of the strand can be readily effected by adjusting the shank 3 so that the blade l0 and anvil 1 can be brought closer together. In other words, when the wire or strand is unusually heavy, the shank 3 may be adjusted to so readily position the cutting element or blade l0 and anvil 1 that the wire is only partially cut bythe first closing of the toggle lever. After this operation, the lever is opened, the adjusting screw turned in slightly, and the lever again closed thuslmaking further cut into the wire or strand. These operations will be repeated until the heavy wire or strand is entirely cut through.

In the embodiment of the invention as illustrated in Figure 3, the blade 24 carried by 'the vjaw 25 is substantially the same as the jaw I2 as emfbodied'in Figures 1 and`2.

VCoacting with the blade 24 isa cutter member 26 which is also ldisposed beyond the working face of the associated jaw, the same as the anvil 1 in Figure 1. The cutting edge b of 'this member 26 is in direct alignment with the cutting edge c of the bladef24 and it is to be stated that the cutting edge b of the member 26 'is dis- Vtrated in VFigure 4, the cutting blade or member 21 carried by the jaw 28 is reduced by cutting away as at 29, a portion of the side face of the `jaw 28 inwardly so that the same .may have closecontact with the cutting blade or member `30 carried by the second or stationary jaw v3| of the wrench.

As is illustrated in Figure 4, this blade or cutting member 30 is formed by cutting'out a side face of the member and that portion thereof which projects outwardly beyond the jaw 3|. The cut-out portion32 of the member 30 is at Vthe side'disposed through the Yblade or member 21 so that vsaid blades or members 21 andY 30 may pass one another and in substantially close contact, whereby a shearing cutting action is I produced.

The outer faces of the members or blades 21 and 30 are flat and relatively broad and the facility with which it may be assembled -and operated.

I claim:

A tool of the class described, comprising two jaws, a handle rigid with one jaw, the other jaw being pivotally coupled to the handle adjacent to the rigid jaw, a lever means connected with said other jaw for moving the latter relative to the 'first jaw; in combination with wire cutting elements positioned'at the' inner portions of the working faces of the jaws, one of said elements constituting a knife having its cutting edge in the plane of and parallel with the working face of the adjacent jaw and the other element having a part coacting with said cutting edge and positioned in a plane lying in advance of the working face of the jaw with which it is associated, and means for varying the extent of vmovement of one of the jaws toward the other comprising a pivot coupling formingvthe connection between the lever and said other jaw, a toggle link pivoted at one end to said lever behind said pivot coupling and a screw threadably carried by said handle forradjustment longitudinally thereof and having the other end of 'the toggle link in thrust connection with its forward endV the said coacting part of said other element being disposed at an acute angle to the plane of the working face of the jaw with which it is associated to bring the said cutting edge and the said coacting part substantially into parallelism when the jaws are at the limit of their swinging movement one toward the other, and the said other element having a long flat Vanvil face lying in a plane perpendicular to 'the plane of movement of the said knife cutting'edge, said 1 cutting edge contacting the longitudinal center of the anvil face when said elements are closed together.
