United States Patent CABLE CUTTER Louis Rogoif, New Haven, Conn.

Application April 11, 1955, Serial No. 500,498

1 Claim. (Cl. 30-245) This invention relates generally to hand operated cutting tools and is more particularly directed to a novel cable cutter usable for cutting relatively heavy electrical, battery or wire cables, said toolincluding a pair of mutually pivoted superimposed handle elements having a self centering pivot link therebetween for permitting the cutting jaws of the cable cutter to completely pivot over each other for attaining a smooth and desirable cut.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, references being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the novel cable cutter showing the cutting jaws spread apart;

Figure 2 is a fragmentary front elevational view of the novel cable cutting tool, showing the cutting jaws having passed over each other;

Figure 3 is a side elevational view of the novel tool;

Figure 4 is an enlarged fragmentary sectional View taken substantially on line 4--4 of Figure 1; and

Figure 5 is an enlarged fragmentary sectional View taken substantially on line 5--5 of Figure 1 showing the construction through the double pivot.

Indicated generally at is the novel cable cutting tool which includes rigidly pivoted handle members 12 and 14, each including conventional hand guards 16, the handle members 12 and 14 terminating in cutting head portions 18 and 20, respectively.

One of the handles, in this case indicated by 12 includes a thinned out section 22 which forms a stop shoulder 24 on the handle which is engageable by the opposite edge 26 of the handle 14. The handle 14 is pivotally secured to the handle 12 so that the undersurface 28 of said handle 14 is in juxtaposition upon the undercut surface 22 of the handle 12.

The handles in the respective cutter heads are secured by means of a pair of oppositely disposed pivot pins 30 and 32, the pin 30 extending through an aperture 34 through the cutter head having concentrically disposed thereon in engagement with the surface 28 of the handle 14 and its respective cutting head a spacer washer element 36. The pivot pin 32 extends through an aperture 3S in the cutter head 18 and has concentrically disposed thereon a spacer 40 contacting the inner surface 42 of the cutter head 18. Secured on the ends of the pivot elements 30 and 32 are connecting links 44, which are secured thereon in any suitable manner, and which permit relative vertical ICC movement between the cutter heads 18 and 20 as well as permitting said cutter heads to be pivoted across or over the top of each other as seen in Figure 2.

The surfaces 28 and 42 of the cutter heads 20 and 18 are substantially in a single plane and provide a sliding shearing action when the handles 12 and 14 are moved from the position shown in Figure 1, to the position shown in Figure 2 with a cable being cut contained between the cutter heads.

Each of the cutter heads includes a semi-circular cutting portion 46 on the side thereof opposite the sides 28 and 42, said cutting surface being formed by bevelling out a semi-circular recess in the respective cutting heads.

As readily seen in Figures 1 and 2, the semi-circular cutting head portions 46 are oppositely disposed wherein a cable to be cut may be placed therebetween, when leverage is applied to the handles 12 and 14, the cutting head portions 46 will move toward each other and thence over each other whereupon a cable contained therebetween will be readily cut with a minimum of exertion, crushing or deforming of the cable. Continued movement results in the edge 26 of the handle 14 coming in contact with the stop portion 24 of the handle 12 and preventing pinching or injury to the operator.

Various positional directional terms such as front, side, etc., are utilized herein to have only a relative connotation to aid in describing the device and are not intended to require any particular orientation with respect to any external elements.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the inven- Vtion as claimed.

What is claimed as new is as follows:

A self-centering hand tool for shearing cable consisting of a pair of handle members, each of said handle members having opposed cutting head portions, said handle members being crossed at intermediate portions, the intermedi-v ate portions of the handle members being juxtaposed planar surface portions, pivot pin elements extending` laterally fromthe intermediate portions of said handle members, and a pivot link extending between the handle members and being pivotally connected at opposite ends ot each of the pivot pin elements on each handle member as the only connection between the handle members, each handle member being independently pivoted about both pivot pin elements for providing pivotal movement between the link element and handle members and relative longitudinal movement between the handle members.
