IMPROVEMENT IN D Specification forming piirt of Letters Patent N 0. 190,998,

OOR-FASTENINGS.

dated May 22, 1877 application filed October 23, 1876.

To all whom it may concern:

Be it known that I, CHARLES R. ARNOLD, of Bloomingdale, in the county of Essex and State of New York, have invented a new and Improved Door-Fastening, of which the following is a specification:

1n the accompanying drawing, Figure 1 represents a front elevation of my improved door-fastening, and Fig. 2 a horizontal section of the same on line 0 c, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has reference to improvements in the door-fastener for which Letters Patent have heretofore been granted to me under date of April 11, 1876, and N 0. 175,899, so that the application of the same may be facilitated and extended.

The invention consists of the connection of the turning disk-plates that are operated by handles or buttons from either side, with eccentrically pivoted and guided lock-bolts; and it consists, further, of projecting lips of the inside face-plates, forming contact with stop-pins and fastening devices, to secure the disk-plates in locked position.

In the drawing, A represents a door or gate for a barn, stable, or other building; B, the disk-plates that are arranged at both sides of the door ongate, and connected through the same by a center bolt, a, to which they are applied in any suitable manner. The disk-plates are proyided with semicircular or otherwise shaped handles or buttons 0, by which they are readily turned from either side for opening or closing the door. The disk-plates, at one or both sides of the door, have lips or tongue extensions b, that come in contact with stop-pins d to define the extent of swinging motion of the disk-plates.

To the inner turning disk-plate are connected eccentricallypivoted bolts D, that f, and the handle of the dis slide in guide-staples of the door, and enter sockets of the door-frame, so as to securely lock the door or open the same, according as the disk-plates are turned in one or opposite direction.

The opening of the bolts may be prevented either by a detachable locking-pin, c, that is set into a socket-hole of the door, on the side of the lip, opposite to the fixed stop pin, or by a padlock placed through a fixed staple,

k-plate.

The locking of doors by the sliding bolts is especially designed for large doors, or for double doors, as shown in the drawing, the second door locking them by a tongue-extension entering a socket-recess of the other door, or turning onto the face of the door. In this manner one or both door-sections may be Opened with great facility by either turning one or both disk-plates, the locking devices being withdrawn jointly with the turning of the plates.

Having thus claim as new an Patent- 1. The combination of front and rear plates B, having handles or buttons U, and turning on a connecting center-bolt, a, passing through the door, with eccentrically pivoted and sliding lock-bolts D D, operated by the plates from either side of the door, substantially as and for the purpose set forth.

2. The combination of the turning front and rear plates B of a door, having handles or buttons 0 and lip or tongue extensions b, with fixed stop-pins e d and suitable fastening devices, substantially as set forth.
