WIRE CUTTER.

Application filed July 12,

tain new and useful Improvements in Wire Cutters; and I do hereby declare the following to be a full, clear, and exact description .of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements .in wire cutters especially adapted for cutting wire entanglements in warfare.

An important object of my invention is to provide a wire cutter of the, character described which is disposed forwardly of an armored motor car, tank or other vehicle used in warfare.

A further object of the invention is to provide a device of the character described which may be applied to anarmored motor car, and so forth, in a highly expeditious manner and with but slight variation in the structure of the vehicle.

A further object of the invention is to provide a wire cutting implement adapted for attachment to an armored motor car or tank, which is positive in its operation and required no attention from the operator of the vehicle.

Other objects and advantages of the invention will be apparent in the course of the following description.

In the accompanying drawings forming a part of this specification and in which llke numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of my improved wire cutting implement,

Figure 2 isa side elevation of a cutting blade of my improved wire cutting device,

Figure 3 is a central vertical sectional view through my improved wire cutter, and,

Figure 4 is-a plan view of my improved wire cutting device attached toa source of power.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 5 designates a rotary .blade corresponding in structure to a coacting rotary blade 6. The blades 5 and 6 are mounted on a stationary shaft 7 and are adapted to partake of rotary movements. in pp s te directions. The shaft Specification ofvLetters Patent.

Patented Apr. 25, 1922. 1918. Serial No. 244,588.

7 is journaled through the forward end of a bracket 8 attached to the front of a tank or armored motor car 9 as at 10. A power shaft 11, extending from the motor of the tank or armored motor car, carries a sprocket 12 driving a sprocket chain 13 arranged on a sprocket gear 14 carried by the blade 5.

Keyed to the shaft 11 and inwardly of the sprocket gear 12 is a gear 15 meshing with a second gear 16; The gear 16 is mounted on a stub shaft 17 which carries a sprocket gear 18. The rotary blade 6 carries a sprocket gear 18 engaging a second sprocket chain 19 extending to the sprocket gear 18. By this particular arrangement of gearing, it is obvious that the blades 5 and 6 are rotated in opposite directions as indicated by the arrows. The rotary blades 5 and 6 carry a series of arcuate shaped members 20 having cutting edges 21 extending radially of the shaft 7. It is apparent that; the wire upon coming between the blades 21 will be severed by the positive rotation of the blades 5 and 6.

The cutting edges of each blade are straight and are arranged radially whereby the cutting edges of one blade will be substantially parallel with the cutting edges of the other blade upon engaging and severing a wire.

In the operation of my device, it is apparent that the rotary blades 5 and 6 are rotated in opposite directions as vhereinbefore described and are mounted forwardly of a tank or motor car and upon coming in engagement with wire entanglements, the cuttin action of the blades 21 seversthe wire.

I'hfle I have shown specific means for causing the blades 5 and 6 to partake of rotary movement in opposite directions, it is obvious that any suitable means ma be employed to accomplish this end and it 1s understood that I may make such minor changes in arrangement and construction of parts as will remain within the spiritof the invention and the appended claim.

having thus described my invention, what I claim 'is':

A wire cutting mechanism comprising a. fixed shaft, a bracket mounting said shaft,-an

cutters, chains trained over said sprocket the cutters are moved in oppesite directions. wheels, second sprocket wheels over which a 1n testlmony whereof I affix my slgnature I said chains are trained, shafts for said second in presence of two witnesses.

sprocket wheels, one of said shafts for the" WLLLIAM J. WARREN. second sprocket wheels being a drive shaft, Witnesses:

and means to drive the shaft for the other GORDON DICK HAMILTON,

sprocket wheel from said drive shaft whereby WILLIAM SMITH JOHNSTON.
