C. A. SCHEELER BULLETPROOF WOVEN WIRE FABRIC Filed April 9, 1926 Patented Nov. 15, 1927.
UNITED STATES CHARLES A. SCHEELER, OF BUFFALO, NEW YORK. ASSIGNOR TO BUFFALO WIRE WORKS PATENT OFFICE.
00., OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.
. BULLETIBOOF WOVEN-WIRE FABRIC.
Application filed April 9,
This invention relates to a woven wire fabric which is more particularly designed to protect custodians of valuables from the bullets of bandits in attempting robbery.
Heretofore the cages which enclosed the tellers of banks and the money in their keeping usually consisted of ordinary woven wire fabric which was incapable of resisting the penetrating power of bullets shot from standard firearms and this left the ofiicials and the funds or other valuables in their charge an easy prey to the bandits who were holding up the banker other depositary. and often enabled them to get away safely with the valuables.
It is the object of this invention to provide a woven metal wire fabric of such composition that the same can not be pierced by bullets fired from the usual firearms but which will stop the passage of the bullets and shred the same during the impact thereof against the protecting fabric or screen and thereby save harmless the custodian as well as prevent loss of the property under his care.
In the accompanying drawings Figure 1, is a rear view of a woven wire fabric or screen made of my improved composition and showing the manner in which the bullet is arrested and shredded upon striking the screen.
Figure 2, is a front view of the same.
Figure 3, is a side view thereof showing the warp wires in elevation.
Figure 4, is a similar view showing the woof or weft wires in elevation.
In the metallic woven fabric or screen shown in these figures the numeral 5 represents the warp or longitudinal wires and 6 the woof, weft or transverse wires which are interwoven in any suitable and well known manner so as to produce a mesh of comparatively small size.
The composition of this wire is such that it is sufficiently hard, tough, strong and flexible to yield under the impact of a bullet and yet not break or rupture nor displace the wires so as to appreciably enlarge the mesh 1926. Serial No. 100,946.
of the screen and permit the passage of the bullet. Instead of this the screen completely obstructs the passage of the bullet and causes the front end of the same which passes through some of the meshes tobecome shredded. as shown at 7, while the rear end of the bullet which has not passed through the screen is left intact, as shown at 8. The result is that the bullet merely penetrates the screen partly and is impaled thereon and its force is spent in the operation of cutting the same into shreds by the crossed wires with which it engages, thereby rendering the same harmless and also avoiding rupture of the screen. Even if some parts of the bullet should pass through the screen the force of the same is so nearly spent and the direction of travel has been deflected that there is no liability of the person attacked being injured.
The ingredients in the composition which embodies my invention and of which the wires of this improved screen are made consists of manganese, sulphur, phosphorus, silicon and carbon. and the preferred proportions of the ingredients in this composition consist of manganese 1.10 to 1.20 parts. sulphur .05 and less parts, phosphorus .025 and less parts, silicon .08 to .15 parts, and carbon .50 to .60 parts. These ingredients may be combined in any manner well known and approved in metallurgy.
Wire made from an alloy or composition containing these ingredients and proportions and drawn of the requisite gage and woven into a fabric of comparatively small mesh will provide a protecting screen having the capacity of resisting the penetration of bullets as above described.
I claim as my invention:
A bullet proof metallic woven fabric hav-- ing its wires composed of 1.10 to 1.20 parts of manganese, .05 or less parts of sulphur, .025 or less parts of phosphorus, .08 to .15 parts of silicon, and .50 to .60 parts of car- In testimony whereof I afiix my signature.
CHARLES A. SCHEELER.
