It is to be understood, of
specic embodiments of the invention, changes inform, construction, and method of assembly and application, may be made within the scope of the appended claims.
We claim: v 'v f 1. Means for sealing the key slot of aj lock comprising, an element formed to enter the key slot of a lock Vand hook upon a lockpart,l and a malleable material mounted upon the element and movable into engagement with the face of the lock. f i
2. Means for sealing the key slot ofY a 'lock comprising, an element formed to enter the key slot and hook upon a lock part and having an irregular body portion, and a body of material that will yield under pressure mounted upon the course, that whileY we have herein shown and described, but two irregular portion of said element and movable into engagement with the lock face.
3. Means for sealing the key slot of a lock comprising, a wire having one end bent to form a hook and the other end bent to form a loop with the terminal portion of said end detachably engaging the body of the wire, and the body of the wire having a deformed section, and a body of malleable. material adjustably` mounted on saidwire and having a portionformed to enter the key slot to prevent rotation of the body relative to the lock. v
4. Means for sealing the key slot of a lock comprising 'a body of malleable material having holesv formed therein and passing therethrough, anda wire slidably engaging each hole, one wire having a hook vformed on one end thereof and a'loopon the other end thereof.
