@ttumegm UNITED STATES WILLIAM H. MOTT, OF NEW YORK, N. Y.
IMPROVEMENT IN DOOR-LATCHES.
Specification forming part of Letters Patent No. 127,505, dated June 4, 1872.
Specification describing an Improvement in Double-Head Latch-Locks, invented by WIL- LIAM H. MoTT, of the city, county, and State of New York.
rlhe invention consists in lapping and slotted latches having pins and shoulders, a lever having holes and peculiar surface, and a double wire spring, combined, as described, with lock-case and plate, all as hereinafter described.
In the accompanying drawing, Figure l represents an inside view of the lock, the covering-plate being removed to show the arrangement of the latches, lever, and springs. Fig. 2 is a cross-sectionv of Fig. l, taken on the line Similar letters of reference indicate corresponding parts.
A and B are the latch-bolts. D is the double spring. The latches are made to lap onto each other, as seen in the cross-section. The interior portion of each latch-bolt has a slot, z'. The slots receive a guide-lug, O, (seen in dotted 1ines,) cast on the case, by which the latch-bolts are kept in place as they `move out or in. Each latch has a pin, j', which" eceives the lever G. The latter has holes, as's en at g h, which a1- low it to be placed loosely on the projecting pins, where it is held by the plate I by means of a single screw passing through the plate and entering the screw-hole J of the case. k represents a shoulder on each of the latch- C is the lever.
. bolts, against which the springs D work. As
E is the lockcase.l
Fig. l. Any kind of `springs may be used for this purpose. The spring bears against the latch-bolts with a constant pressure. Lis the key-hole.
In throwing back the latch-bolt A the bit77 of the key bears against the lever C on the surface m, This causes the lever to turn on the pin fat Iva as on a pivot, and, consequently, moves back the hole g, which throws the latch A. In throwing the other latch, B, the key enters the recess N, causing the lever to turn on the pin f at g and thereby draw back the latch-bolt B. It will be seen that the hole IL in the lever is slotted, which gives all the play necessary on the pin f to allow the lever to turn, as described.
In this lock the latch-bolts are connected by the lever, so that neither bolt would Work without the other; but in operating one the other is not disturbed.
It will be seen that the lock may be placed l Witnesses:
