DOOR-LATCH.
Patented May 30,18 76.
FIG-3 H Ddom INVENTOR- UNITED STATES PATENT OFFIo.
oRvELLAs H. GILBERT, OF CHICAGO, ILLINOIS.
IMPROVEMENITVIN DOOR-LATCHES.
Specification forming part of Letters Patent No. 177,933, dated May 30, 1876; application filed April 1, 1876.
.To all '[vlwm tt may concern:
Be it known that I, ORVELLAS HENRY GILBERT, of Chicago, in the county of Cook, and State of Illinois, have invented a new and useful Improvement in Door-Latch Bolts and Locks; and I do herebydeclare the fol: lowing to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is inside view of lock. Fig. 2 is a perspective view of rose, escutcheon, knob, and lever Fig. 3, cross-section.
In the accompanying drawing, A represents my improved lock; A, the latch-bolt,provided with the slot or mortise B. dis a spiral spring, one end bearing against the lug d attached to the case ofthe lock, and the opposite end bear- .ingagainst thelug b, projecting from the latchbolt. B is a key-bolt provided with a slot upon its lower end to allow it to work vertically on the pin b. O is a tumbler, one end pivoted to the key-bolt, and the opposite end provided with a mortise, 0, upon each side of which are projections, c. U is a rose provided with the slot at, through which passes the lever D. D is the shank, and 1) the knob.
It will be observed that the rose, the shank, and the key escutcheon are all cast in one piece. The lever is then placed in position in the mortise, and the pin or screw d passed through the lips on each side of the mortise, and through the lever, to hold it in position. Aiter the lock is placed in position in the door the ends of the levers D are placed in the mortise B inthe end of the bolt A, and the roseis then secured to the door, the screws entering. the doorabove and below the lock,
which operation secures the key-hole escutcheon and the knob at the same time.
It will also be observed that the knob is secured to the outer end of the shank, the Washer 12 forming the shoulder against which it rests. In opening the door the knob does not turn as'in ordinary looks. The hand, coming in contact with the lever D, presses the same toward the shank. The opposite end strikes the end of the mortise B, and 'moves the bolt in that direction enough to cause it to be disengaged from the casing and allow the door to open. When the hand is released the spring a throws the bolt back to its original position. 7
A look constructed in this manner obviates the liability of the knobs becoming loose, and
the wear of the spindle in ordinary locks, which plate 0, cast in one piece, and proi ided with j mortise B, in combination with projecting lips and lever D passing-through a mortise, B, in the latch-bolt A] and? pivoted to said roseplate, substantiall a and for the purposes specified. r
The above specificatici signed by me this 9th day of March,'l876.
ORVELLAS H. GILBERT.
