Letters Patent No. 114,608. dated May 9, 1871; antedated May 2, 1871.

IMPROVEMENT IN DOOR-LATCH ES.

The Schedule referred to in these Letters Patent and making part of the same.

I, HENRY Snnnncs, of Utica, in the county of Oneida and State of New York, have invented certain Improvements in Door-Latches, of which the follow- Description of the Accompanying Drawing. I

Figure 1 is a perspective view of the latch attached to a door that is hinged to a frame forthe purpose of showing its operation.

Figure 2, a side view of the bent lever.

Figure 3, a view of the latch-plate.

Figure 4, a side view of the latch.

Figure 5,a horizontal section made through the latch and door in the region of the center of latch K, fig. 1.

General Description.

A is the handle of lever T, through which motion is communicated to latch K by reason of its fulcrum being at the point where slot B embraces a portion of case N, and the shorter arm, 0, extending under latch K.

Case N forms acovering to the latch, and serves as a bracket to hold lever T, and, in connection with plate 1, forms a guide for latch K to operate in.

The latch-plate I has a hole at H for the reception of hub S of latch K, and a raised projection at J to fill the opening in case N opposite the one occupied by latch K. Plate I is reversible, so that the latch can be used as either right or left-hand.

Shaft F is square where it enters latch K, and terminates at that end with a nut, O, which holds the shaft and latch to their places; at its other end it terminates with an oifset-haudle, L, to keep the operators hand at a sufiicient distance from the door-frame to avoid contact therewith in opening and closing the door.

Latch K has a stud, R, to which is attached one end of a coiled spring, P; the other end of the spring should be fastened to the door in such a manner as to draw the latch down.

I claim as my invention-- The lever T, with outwardly-curved handle A, slot B, and arm 0, extending under pivoted latch K, to which latter is attached a spring, P, all arranged and operating as herein set forth.

HENRY SANDERS.
