UNITED STATES PATENT OFFICE.
FREDERICK H. WOOD, OF CHICAGO, ILLINOIS.
LOCK AND SEAL FOR SCREWS.
Application filed September %4, 1926. Serial No. 139,567.
The screw being first driven, when the staple is driven home the projection formed by the head of the staple will engage the slot of the screw forcing the humps on the prongs to engage the undercut wall of the screw. The head of the staple binding in the slot of the screw, and the humps engaging the under cut wall of the screw, makes it impos-' sible to remove the staple without mutilating the material into which the screw and staple have been driven; and as the head of the staple fills the slot of the screw, a screw driver cannot be used until the staple has been removed. The staple therefore forms a lock for the screw, to prevent its removal or its working loose. It also forms a seal in that it cannot be removed without an indication that it has been tampered with.
The purpose of this invention is to prevent pilfering from packages in transit and to prevent the removal of screws generally wherever it is desirable to protect them, and to prevent screws working loose. It is intended particularly with screws designed to be driven like nails and then turned with a screw driver to make them hold firmly.
Having described the purpose of my invention the nature-of the same will be fully understood from the description I give below, when considered in connection with the 7 the screw, before the staple hasbeen driven beyond the bend. Figure 3 represents a modified form of staple intended for the larger screws, in the position it would 00- cupy after the screw and the staple have been driven. Figure 4 shows the same staple as of Figure 3 before it is entirely driven.
In Figure 1 A is a standard screw with the usual cross slot B and undercut wall of the periphery of the screw hea'd G. D is one of two prongs of the staple extending at an angle from its head, the prongs having a bend or hump at E and the head forming a projection on the side opposite from the hump.
Figure 2 is intended to show that when the staple is fully driven, being formed of spring metal it will either force the wood,
permitting the staple to occupy its position as of igure 1, or its resilience will cause it to b1nd 1n the slot of the-screw;
In Figures 3 and 4, the modified form of staple, I) has. a hump F which on entering the slot because of the undercut periphery of the screw head, reaches a point where it is clear of the screw, and as the staple is driven until the projection G enters the slot, the staple is forced over until the hump engages the under cut periphery of the screw head 7 at C.
Staples such as these indicated may be used where metal is screwed onto wood or where the screw is driven into metal, holes being drilled for the staple, and the hump made at such position on the prong of the staple as to meet the requirement, the spring metal of the staple binding the staple in the slot of the screw.
I claim A staple for use in connection with a standard screw head with the usual cross slot and under cut periphery, comprising a head adapted to fit snugly into the cross slot, and prongs extending at an angle therefrom through the ends of said slot, each of said prongs having a hump on one side, and said head forming a projection on the opposite side, the projection forcing the hump into engagement with the undercut wall of the screw head.
