WIRE-CUTTER.
Specification of Letters Patent.
Patented Mar. 25, 1919.
Application filed January 25, 1918. Serial No.'213,633.
To all whom it may concern: Be it known that I,- HIPPQLYTE Roaa- NOFF, a citizen of Russia, residing at 200 West 59th St., in the city of New York, in the county of New York, State of New York, have invented certain new and useful Improvements in -Wire-Cutters; and I do hereby declare the following to be a full,
' clear, and exact description of the inven- The present invention relates to wire cut- ,ters of a type particularly suited for war purposes. The device is light in weight, is
powerful in its action, 'is simple in construction, andsuch parts as are most likely to ll of Fig. 3;
"pletion of the cut,
deterioration by wear or abuse are easily renewable.
The device comprises a stationary member suitable for detachable connection to a handle which may be the barrel of a gun, and to this stationary member is pivoted a supporting member wherein the wire-cutting knives are carried. One ofthese knives is so mounted that it can be cammed toward the other with a wiping movement while the knife sup-port swings. on its pivotal connection with a stationary member and consequently swings about the wire to be cut. The result is a powerful shearing action on the wire to be cut.
Other details and advantages of the invention will become clear from the following detail description taken in conjunction with the accompanying drawings, wherein:
Figure 1 is an elevation of the wire-cutter attached to the barrel of a gun;
Fig. 2 is a similar view with the gun replaced by another form of handle Fig. 3 is a side elevation with a partof the knifersupporting member broken away' to show the cam and the pivot about which it moves 5 Fig. 4 1s a transverse section on the line Fig. 5 shows the knife-supporting member near the commencement of its swing and with the knives just contacting with the wire to be cut; Y
' Fig. 6 is a similar view at or near com-' Figs. 8 and 9 are details of the cam mechanism; and V 1 V Fig. 10 is an elevation of a slightly modified form. r
In the construction illustrated in Figs. 1 to 9 inclusive, the stationary member 1 is of triangular outline and can be detachably connected to the barrel of a gun or other suitable operating handle by a. clipcomprising abase 2riveted to member 1 and a shield 3 detachably secured thereto by apair of bolts 4: and wing nuts 5. At the front of stationary member 1 is a pivot pin 6 and eccentric with said pin and integral with stationary member 1 is a cam 7 (Fig. 8) whereby one of the knives is actuated.
Mounted to swing on pivot pin 6 is a knife-supporting housing 8 in which the squared head of pivot pin 6 is seated, as shown in Fig. 4. At the opposite end of this knife-supporting housing is rigidly but detachably mounted, -a wire-cutting blade 9 held in place by a'rivet 10. The opposing blade 11 is rigidlybut detachably connected by a clip 12 andrivets to one end of a carrier 13. This carrier engages with a rivet 14.- about which the carrier may swing, but is slotted to permit longitudinal movement of the carrier when the knives are, to be brought together. The opposite end of the knife carrier 13 is rounded to fit against the edge of cani 7 so that when the knife support swings downward away from the stationary member asshown in Fig. 5 the knife holder 13 will be cammed forward to advance one of the knife blades toward the other, but in addition, the cammed end of the knife holder will swing inward thereby swinging the holder about-pivot 1i and causing its-knife to approach the opposing knife with-a wiping movement.
As a means for retracting the movable blade after the cut is complete, there is provided a plate 15 (Fig. 9) i'iveted to the knifecarr'ier and having a circu ar opcning adapted to receive a shoulder 16 (Figs. 4: and- 8) of cam 7. This shoulder serves as a cam and through its pull (in plate 15 positively retracts the movable blade on the backward swing ofthe knife carrier.
As a means for facilitating "or automati- Fig. 7 is a fragmentary section illustrat: ing the spring by which the knife support is normally held against the stationary member;
cally producing that backward swing of the knife-support there is provided a coiled spring 17 '(Fig. 7), one nd of which is anchored at 18 to stationary mergber 1 and the other end of which is" attached a t-l9 (Fig. i) to pivot pin 6. Because of the rigid connection between pin 6 and the knife-supporting housing 8, the spring acts to Swing the support against the" stationary member when "the device is not in use."
The arrangement of elements above d e scribed is well adapted for war purposes and for night use. The muzzle of the gun can be thrust through a wire entanglement and on a backward pull on the gun the wire to be cut will slide, along the inclined guiding face of stationary member 1 and will i be received between the separated knife the strain on the device.
blades. A 1 further pull on the gun will cause the knife support to swing on its pivot thereby camming one of the bladestoward the other with a wiping movement; But
plained above, the knives are wellprotected Y from destruction one on the other. Assoon stationary member 23 is not of triangular as the wire parts on the out, the knife support is free to swing back to its initial position through the action of spring 17. In the modification illustrated in Fig. 10 the outline as" in Fig. l, but carries a stop 24 to limit the upward swing of the knife carrier.
The base 25 of the attaching means is integral with member 23, but other details of the attachment are as above described.
The pivotally mounted knife-support, the" actuating cam, the retracting plate and other features are as above described in connection with Fig. 1, and the clip orplate 25-whereby the knife 26 is rigidly but removably attached to its carrier by means of rivets, has one end curved upward to form a stop finger 27 normally engaging thestationary member 23when the knives are separated and movable downward away from that member when the knives are cammed together to cut the wire.
I claim: 1. In a wire cutter, the combinatlon of a stationary member having a cam, a support pivoted to said member, a wire cuttingblade rigidly mounted in said support,a'second' blade, and acarrier therefor mounted to slide in'said support and actuated by said cam with a swinging movement when said blades approach one another.
2. In a. wire cutter, the combination of a stationary member, means for detachably connecting said member to a handle, a knife support pivot-ally connected with said memher, said member having a cam eccentric to the pivot, a pair of knives carried by said knife support, and a holderfor one of said Zknives pivoted to said support but movable long tudinally on said pivot, said holder .engaglng said cam and serving to advance its knife with a wiping movement when said support swings-on its pivotal connectlon with said stationary member.
3. In a wire cutter, the OOIIlblIlfitlOIl of a stationary member adapted forattac-hment to a gun, a knife support pivoted thereto and carrying a detachable knife blade, a
knife holder pivoted to said support but adapted to slide therein while swinging on its pivot, and a cam on said stationary memher and engaging said knife holder to actuate the same. when said knife support, sw ngs on its pivotal connection with said stationary member.
4. In a wire cutter, the combination of a stationary member, a knife support pivoted thereto, a pair of knife blades carried by said support, means for advancing one of the knife bladesutoward the other with. a
I wiping movement when said support swings on its pivotal connectlon wlth .said statlon ary member, and a spring for returning said knife support while simultaneouslyseparating said knives.
5 111 a wire cutter the combination of a f stationary member, a support pivoted thereto and adapted to swing downwardly ,therefrom, a knife blade carried by said support,
