LATCH.

SPECIFICATION forming part of Letters Patent No. 343,348, dated .Tune 8, 1886.

Application filed February 3, 1886. Serial No. 190,668. (Model.)

Tov all whom it may concern:

Be it known that I, WARREN H. TAYLOR, of Stamford, in the countyv of Fairfield and State of Connecticut, have invented a certain new and useful Latch, of which the following is a specilication, reference being had to the accompanying drawings, which illustrate one form of embodiment o1 my invention.

My invention consists iu certain improvements in mortise locks or latches, whereby they are rendered more satisfactory in their operation.

In the accompanying drawings, Figure l is a horizontal section of my device completeas applied to an ordinary door. Fig. 2 is asection showing only the latch appliances taken at right angles to that shown in Fig. l. Fig. 3 is a face view of the latch and latch plate or holder. Y

Referring to the letters upon the drawings, A indicates an ordinary door-latch or lockcase on a door, operated by a partially-rotating spindle, B, and knobs C, and any usual or suitable mechanism, D, connecting the spindle and latch push or plunger E, which corresponds in position, movement, and connections generally with the ordinary sliding latch or `latch-bar in common locks for doors, 85o,

Normally the plunger rests within the lock- H indicates the latch pivoted to any suitable plate or holder, I, countersunk in and secured to a door-jamb. This latch is provided with any suitable light spring, K, tending tc press it gently outward, so that it will project in the path of the end or face plate, F, as illustrated, when shutting a door or drawer, which end plate is really the strike, or corre sponds in function with the ordinary strikeir pushing in the latch when shutting a door o1 drawer. The spring K is preferably a deli cate helical spring mounted in a yoke or frame, K', located directly behind the inclined end o: the latch. This construction offers the mini mum resistance to the necessary movement ir shutting the door.

The latch is inclined on its face L, as usual, so that when it is struck inthe act of shutting a door, Src., it will be pushed inward out ol the way, and then its spring will throw it oui again into the cavity G and latch the door.

I prefer to slightly curve or incline the surface M of the latch end, as shown, for the bet ter fitting or workmanship.

Y I provide 'a stop, N, on the latch, to strikf the plate or holder I, as shown, and limit itf outward oscillation.

I do not claim that a pivoted oscillating spring-latch is broadly new; nor do I claim broadly,a latch pivoted to the jamb of adoor in combination with a pusher mounted in th( door; but

Vhat I do claim to be new, and desire t( secure by Letters Patent of the United StatesI 1s- The combination of the plate I, the latch E pivoted thereto, the yoke K', mounted on the plate I, the spring K, attached to the latch auf to the yokejust behind the head of the latch` with the latch-operating mechanism, substan tially as set forth.

vIn testimony whereof I have hereunto subscribed my name.

WARREN H. TAYLOR.
