HENRY S. WILCOX, 0F WEST MERIDEN, CONNECTICUT.
IMPROVEMENT IN LOCK-FASTENERS.
Specification forming part ot' Letters Patent No. 43,117, dated June i4, i864.
To all whom it may concern:
Be it known that I, HENRY S. WILCOX, of West Meriden, county of New Haven, and State ot' Connecticut, have invented certain new and useful Improvements in KeyiFasteners to Render them Burglar-Proof; and I do hereby declare that the same is described and represented in the following specification and drawings; and toenable others killed in the art to make and use the saine, I will proceed to describe its construction and operation, ret'erring to the drawings, in which the same letters indicate like parts in each of the gures.
The nature of the invention will be clearly perceived from the specification and drawings.
The object designed to be attained by this improvement is to so fasten the key ot' the lock, after it has thrown the lock-bolt forward, that it cannot be vturned either way, so as to throw back the bolt or so as to allow of its being ejected from the lock by the use of burglars7 instruments.
In the accompanying drawings, Figure I shows a view ot' a block, (which represents a door,) into which is fitted alock and latchwith its usual appendages. Fig. 2 shows a modified form of using this improvement, where no knob and spindle are used with a lock.
A is a block of wood, which represents a door. B is a latch. C is a lock-bolt. D represents a knobshank, which is attached to the knob in the usual way, for holding it onto the spindie. E shows the end of the spindle. Gis the bow of a key. His a wire o'r rod of metal, bent at one end into the form ot' a spring` hook, so as to just spring onto the shank D, or its (quivalent, to prevent its dropping ott' after having been placed thereon. I is a thumb screw, which can be readily screwed into the wood-work of a door, when there is no other protuberance convenient, onto which this hook end of the rod or wire H can be sprung after its lower end has been inserted through the bow G of the key. Now, it will readily be seen that when the holt is turned forward hy the action of the key, and while the key remains in that position, (as when it has just turned the bolt forward,) the lower end of the rod H is inserted through the bow of the key, while the hook end is hooked or sprung in to the spindle or knobshank D, or their equivalents, and thus efectually securing the key from being turned or pushed ont ofthe lock from the opposite side of the door by the use of burglars implements.
This device, though cheap and simple, is believed to be sufcient to render the corrmonest lock effective and secure.
I believe I have thus shown the nature, construction, and advantage to be derived from the use of this improvement, so as to enable a person skilled to make and use the same.
What I claim, therefore, as of my own invention, and desire to secure by Letters Patent, is
The rod H, constructed as described, in combination vsith the shank D, keybow G, or their equivalents.
In witness whereofl have hereunto set my hand and afxed my seal.
HENRY S. WILCOX.
