COMBINED LATCH AND BOLT. 7 Q 7 PatentedMarchliB. 187 No.188,308.
NJETERQ PHuTc-UTHOGRAPHER. WASMINGTOl D c ATENT OFFICE.
IMPROVEMENT IN COMBINED LATCH AND BOLT.
Specification forming part of Letters Patent No. 188,308, dated March 13, 1877; application filed June 11, 1875.
To all whom it may concern Be it known that I, JACOB A. SHERMAN, of the city and State of New York, have invented an Improvement in Lock-Bolts, of which the following is a specification:
Bolts for doors, safes, 8w, have been moved endwise by the action of a pinion upon a rack, such pinion being turned by a handle attached to the same, or otherwise. A bolt has been projected by a pinion acted upon by a key, and a cylindrical case been provided bolt.
In the drawing, Figure 1 is a longitudinal vertical section of the bolt, and Fig. 2 is a sectional plan at the key.
The case a is cylindrical, and made with a screw, 12, at the inner end, and a circular flange, c, at the outer end; and this case is easily inserted into a hole bored for its reception, and secured in place by the screw b. The bolt d fits within the case a, and the rear portion or shank is reduced and formed as a rack, e. f is a spring, that serves to project the bolt when used as a latch.
The pinion l is made with teeth that taper toward the end of the key, so that the pinion is inserted with facility into the rack-teeth, and by the rotation of the pinion the bolt can be moved endwise in either direction.
If the pinion Z is made with a shank, it may be used as a key. It, however, will usually be connected with the handle m, and the same are held in place by the rose or washer n, that is screwed to the face of the door.
At It is an escutcheon for the key-hole, the latter being bored at right angles to the bolt. The key 0 is inserted from the opposite side to the handle m, and acts upon the talon p of the latch portion d. The rack e and latch are connected by the tongue q, running between the forks of the rack, and the crosspins 2, or stops, determine the amount of motion, so that the latch can be operated upon by the key without moving the rack or handle.
The collar 3 around the shank of the latch d serves as an abutment for the spring f, and this collar is held by the lateral pin or screw 5, that enters a groove in said collar. When this clamping-screw holds the collar, the latch d is operative as a latch only 5 but when the screw is slackened the latch can be projected by the action of the pinion I, so as to form a bolt. When this is done the talon p is moved forward, so that the key becomes useless, or cannot be inserted.
By this construction the latch is available as such for ordinary use, and, when projected as a bolt, the same is very secure, and the key cannot be used.
To hold the latch back entirely out of use, a notch may be provided upon the handleshank, and a pawl, o, pivoted to the rose a, so as to retain the knob and pinion from revolving.
The bolt, when projected, enters a case, 0, that is circular, and inserted into a hole bored into the casing or frame, and within the case 0 is a spring, 8, and button t. The spring and button yield to the bolt or latch as it is moved endwise against the button t,- but when the bolt is withdrawn the button t is projected to the end of the case 0, so as to form a stopper to such bolt-hole, and there by prevent the objectionable appearance that the hole would otherwise present, especially in thejamb of a door.
I claim as my invention 1. The collar 3 around the shank of the latch, forming an abutment for the spring f, in combination with the movable pin or screw 5, rack e, and pinion l, substantially as and for the purposes specified.
2. The talon p for the key upon the inner end of the spring-latch, in combination with the tongue q, rack e, pinion l, and stops 2 2, substantially as set forth.
Signed by me this 23d day of February, A. D. 1874.
J. A. SHERMAN.
