EDWARD H fKENT, OF NEW Y'OR'K,V;N. Y.
Letters Patent No. 108,361, datedvctober 18, 1870.
The Schedule referred to 1n these Letters Patent and m'aking part of the name.
To all whom 'it may concern.-
' Be it known that I, EDWARD H. KENT, of the city, county, and State of New York, have invented a new 4and useful Improvement in Guard-Bolt; and I do proved gaurd-bolt designed tobe used, in .connection with an ordinary spring-bolt, to guard the door from being opened by any one from the outside of the door who mighthave succeeded Ain forcing back the catch- It consists in the combination of the lockingvpin, socket, bolt, and spring, with the ordinary strike or keeper of a spring-bolt, as hereinafter more fully described.
A represents the strike or keeper of an ordinary spring-bolt or latch, upon the inner side of which is cast a socket, B, 'which is to be letl into a 'recess formed for its reception in the door-casio g.
C is a bolt placed in the socket B.
The forward end ofthe bolt C is beveled 'effin the same manner as the forwardfend of an ordinary latchbolt; but upon its outer angle, so that when the door is closed, the bevel of the latch-bolt may correspond with the bevel of the guard-bolt C,.the two beveledA ends thus lcorresponding with and overlapping each' other, as indicated in tig. 1.@
lThe inner end of the bolt'G is made small to receive the coiled-wire spring D, one endfof which rest-s against, and may be secured to the shoulder formed upon the said bolt O, and the other end of which rests against, and maybe secured to the bottom of the socket B, which is perforated'to allow the inner endv ofthe bolt C t9 pass through, whenthe said bo`lt is pushed back, into the said socket. y
The spring D should be made so weak that the spring of the latch-bolt, when the door is shut, may
both force out said latch-bolt, and also compress thc spring D and force the guard-bolt O into the socket B. At the same time the spring D shouldhave suicient strength to carry the guard-bolt C out promptly when the latch-bolt iswthdrawn, so that the twobolts may move out together, and with their beveled eudsover` lapped.
' By this construction should any one, m trying to open the door from the outside, succeed 1n forcing back the latcl1bolt,vthe guard-boltO will move out,
and, as the said latch-bolt leaves the mortise of the keeper A, the beveled end of the guard-bolt G will enterjthe mortise of the lock, so that'it will be impossible to open the door.
E isa pin passing in through a hole iu 'the side of the socket B, and entering a hole in the bolt O.
Upon the outer end of the pin E is formed a small knob for convenience in operating it, and upon its side is formed, or to it is attached, a small projection or pin, F, which, when the-pin E is pushed in to hold the boltC from operating, enters a slot in the side ot' the socket in which the piu-E works, and which, when the pin E is drawn out to allow the bolt O to operate, rests against the edge ofthe said' socket or hole.
The pin E is also provided with a coiled or other spring, G, by the action of which it is held in place when holding the bolt O in place in the said socket B.
,Having thus described my invention,
I claim as new and desire to secure by Letters Patent- The combination ot' the locking piu'E Fand spring G with the guard-bolt B O D, and keeper A, substantially as herein shown and described, and for the purpose set forth.
The above specification of my invention signed by me this 2d day of August, 1870.
Witnesses: EDWARD H. KENT. JAMES T. GRAHAM, T. B. Mosman.
