IMPROVEMENT IN LATCHES EOR DCORS AND GATES.

Specification forming part of Letters Patent No. 155,574, dated October 6, 1574; application filed July 22, 1874.

. Doors, Gates, 8vo., of which the following is a specification:

The nature of myinvention relates to a new and improved fastening for doors, gates, and

the like; and it consists in a spring-catch, pivoted or journaled in a suitable plate, which is rigidly secured to the frame or post, and it is provided with an arm, to which is attached a string or wire. This wire is led through the frame, and to the opposite end is a knob.

By this means the bar, which is rigidly attached to the gate or door, may beA liberated from the catch, and the gate or door swung open. i

The accompanying drawings, which form a part of this specification, show in Figure l a longitudinal section, illustrating my invention; and in Fig. 2, a plan view.

Referring to the drawings, A is the stationary frame or post, and B the door or gate.

-Securely and rigidly attached to this frame or post, by any suitable means, is the plate O. This plate C furnishes journal-bearings for the spring-catch D. This spring-catch is provided with an inclined surface, which is adapted to work in connection with another inclined surface on the end of the bar E. A spring, F, spiral or otherwise, is so situated under the catch that it operates against the action of the door, gate, &c.,-and holds the same in position. G is an arm, one side of which furnishes the inclined surface before mentioned, to which is attached to the string or wire g. This wire passes through the frame or post, and is provided at the other end with a suitable knob or handle.

The bar E, it will be noticed, is rigidly attached to the door or gate, and in the act of closing the samethe inclined surface of the bar, acting on the inclined surf'ace of` the spring-catch, forces the same outward, compressing the spring until the bar has passed the spring catch, which immediately, c0111- pelled by the spring, assumes a position above the bar, and thus the door is securely fastened.

The spring-catch is operated from the opposite side by simply pulling on the string or wire g, as can readily be seen.

I claim- The spring-catch D, having arm G journaled in the piece C, and attached to the door-frame A, and the string g, in combination with the rigid plate E on the swinging door B, as shown and specified.

In testimony that I claim the foregoing as my own I afx my signature in presence of' two witnesses.
