LATCH.
SPECIFICATION forming part of Letters Patent No. 232,509, dated September 21, 1880.
Application filed April 12, 1880.
To all whom it may concern:
Be it known that I, THOMAS W. KIMBELL, a resident of New York, in the county of New York, in the State of New York, have invented a new, useful, and important Improvement in DoorLocks, described in this` specification.
My invention consists in an improvement upon that class of locks which are unlocked from the outside with a key, from the inside by a handle, are locked when the door is closed, and are arranged to draw the bolts at the `bottom and top of the door when being unlocked.
Figure l is a perspective view of the lock and bolts on the inner side of a door. Fig. 2 is a rear View of the same, with the bolt partly drawn. Fig. 3 is a horizontal section of the same.
In the form of lock shown, A is the case. B is a bolt. C is a device to draw the bolt, which has a cam, Fto turn in a recess in the bolt to draw it, a key-receptacle, d, a handle, E, and ears g g, for the attachment of the chains 1L l1., by which the spring-bolts H I are operated. K is a spring for retracting the bolt after it is drawn.
The case has a slot, l, for a button, m, to fasten the device C when the door-bolts are drawn and hold them back. The bolt has a stud, n, to move in a groove, o, on the back plate, F, to center the bolt. y i Changes in the details of construction and operation maybe made within the scope of my (Model. l
'claim- 1. The combination of case A, having slot l and groove o, bolt B, having stud n, device O, having cam F and key-receptacle d., handle E, and ears g g, chains h h, bolts H I, spring K, and button on, substantially as set forth.
2. The combination of case A, having groove o, bolt B, having stud n, device C, having cam F, key-receptacle d, handle E, and ears g g, chains h h, bolts H I, and spring K, substantially as set forth.
3. rllhe combination of a latch-case having a guide for the bolt, a bolt having a stud and a retracting-spring, a device having a key-receptacle on one side, a handle on the other, a cam to move the bolt, and ears to connect bolts for the top and bottom of a door, substantially as described.`
In testimony whereof I hereunto subscribe my signature, in the presence of two attesting witnesses, on the 10th day of March, 1880.
THOMAS W. KIMBELL.
