WIRE CABLE CUTTER Filed Oct. 8, 1936 I a aim MW; /0 A Snow;
Patented July 13, 1937 WIRE CABLE CUTTER Clarence 0. Smith and Harold D. Andrews, Auburn, Maine Application October 8, 1936, Serial No. 104,699
This invention relates to a wire cable cutter more particularly designed to cut steel wire and it aims to provide a construction whereby the cutting apparatus, without the aid of additional 5 tools, will satisfactorily and easily cut the metallic wire cable Without fraying the ends or leaving sharp edges.
Another object is to provide a structure wherein hardened steel cutting elements are renewably mounted and means is provided to prevent spreading or crowding of parts of the cutting edges while shearing the cable.
The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.
In said drawing:
Figure 1 is a view in side elevation of the improved cutting device;
Figure 2 is a plan view thereof;
Figure 3 is an enlarged vertical sectional view taken on the line 33 of Figure 1; and
Figure 4 is a detail section taken on the line 4 4 of Figure 2.
Referring specifically to the drawing wherein like reference characters designate like or similar parts, a suitable base is provided as at It, for instance, having front and rear feet as at II, 9 and a central upright beam l2, such parts as well as all parts of the device being metallic.
Welded against one side of the plate or beam l2 and extending above the same, is a block l3.
Pivoted to the block 53 as by means of a removable and adjustable bolt I l, is a shearing lever l5 operating in vertical line above the beam or plate l2, and provided with a suitable handle it of any desired length. Welded to the said beam or plate E2 on the opposite side to block 93, a) is a bearing lug ii, the lever l5 being disposed between such lug and block l3 and the bolt It also passing therethrough.
Said block it and the lever i5 carry coacting hardened steel cutters i8 and I9, respectively. Said cutters are preferably arcuate as shown, each having a semicircular cutting edge at 20, the cutters EB and is being adapted to contact during the shearing operation, and the cutters being beveled as at 2! in a direction away from the plane of cutting. Since the cutters are semicircular, they collectively completely encircle the steel wire cable or the like being severed and the result is accomplished without fraying the ends or leaving sharp edges thereon.
On the opposite side of the beam or plate l2 adjacent the rear end of the block [3, is a vertical post 22, welded to such element [2 and being of such height as to cause engagement at the inner surface thereof by the lever I5, during the shearing operation on the wire cable or the like so as to prevent spreading or crowding apart of the cutting edges 20. It will be realized that the lever 55 snugly fits the block i3, lug Ill and backing post 22 to stabilize the construction and especially prevent the aforesaid crowding and spreading.
In the operation of the device, the steel cable or the like is disposed in the out-out portion of the cutter 58, while the lever i5 is raised, whereupon such levcr is manually depressed so that its notch will engage the steel cable or the like and through continued depression of handle IS, the cutters will sever the steel cable or the like. It will be realized that the cutters l8 and [9 may be readily renewed when worn.
We claim as our invention:
1. A device of the class described, comprising a plate, a block secured to one side thereof having an arcuate cutting edge, a lever, a pivot member connecting the lever to the block over the plate and having an arcuate cutting edge to jointly with the aforesaid cutting edge surround and cut a cable, a backing post on the opposite side of the plate to said block engageable by the lever to prevent spreading thereof relatively to the block 0 during a cutting operation, and a lug on the same side of the plate to the backing post engaging the lever, the said pivot member for the lever passing through said lug, the lever and said block.
2. A device of the class described, comprising a plate, a block secured to one side thereof having an arcuate cutting edge, a lever pivoted to the block over the plate and having an arcuate cutting edge to jointly with the aforesaid cutting edge surround and cut a cable, a backing post on the opposite side of the plate to said block engageable by the lever to prevent spreading thereof relatively to the block during a cutting operation, a lug on the same side of the plate to the backing post engaging the lever, the pivot for the lever being a bolt passing through said lug, the lever and said block, said block, lug and post being welded to said plate, and removable cutter members on said lever and block providing: said arcuate cutting edges.
