IMPROVEMENT IN DOOR AND GATE SPRINGS.

Specification forming part of Letters Patent No. 116,196, dated June 20, 1871.

To all whom it may concern:

Be it known that I, PHILIP KERN, of the city of Dayton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Door and Gate Springs, of which the following is a specification:

My invention relates to a fastening device whereby the said spring may be easily and cheaply attached to the said door and frame, and whereby said door and spring may be quickly removed from the door-frame and as quickly replaced.

In the accompanying drawing, Figure l is a side elevation of saloon-door, to which is attached a flat spring in the position which I regard as novel, said elevation also showing the application of my device for attaching said spring to the door and frame. Fig. 2 is a fullsized elevation, in perspective, of the front,

side, and end of my attaching device. Fig. 3 is a view, in perspective, of thefront, side, and end of one of the varieties of spring used by me.

General Description.

A A are, respectively, the right and left side pieces of the frame of saloon-door. B is the lintel or head-piece of said. door-frame, while 0 is the sill or threshold of the same. E D H D is a slatted door, of which E and H are, respectively, the right and left side pieces. D is the top, and D the bottom of said door. This door swings upon hinges of any'desired variety. For saloon-doors such hinges are pre:

ferred as will allow the door to be taken off from its hinges without unscrewing a part of each hinge. One simple style of such hinge is shown in Fig. 1 of drawing, the pivots of each hinge fastened to the side piece H being marked N, and the complimentary part of each tached to the lower part of A at a short distance from the end of said spring. This spring might be attached so that it would cross in a direction exactly the reverse of what it now doesthat is, the top of S might be fastened on the upper and inside portion of the frame A, and the bottom of S on the lower part of the edge of the door nearest the frame A. The spring is attached by any suitable fastening. The method of fastening I'find most convenient is that shown in the drawing. I attach the upper point of the spring in the door at K by a screw. Just below K I attach a fastening (see Fig. 2) resembling a buckle. This fastening consists of a flat plate, T, having an arch or bridge, V, supported by shoulder X X, and raised high enough above the plate to allow the spring to be passed between said arch and the plate T. Plate T may be made light by casting a hole in the inside of the plate.

In plate T are bored holes for the reception of screws or nails. This fastening is attached to the edge of the door, immediately below the screw K, by screws P P, so that the spring passes oier the flat piece T and under the bridge V. To attach the lower end of the spring to side piece A I employ another of these fastenings, secured by screws at P P,

Claim.

What I claim as new is The spring S, when attached-at one end to the door or frame, while the other end passes under a bridge, V, which resists torsion, but

permits longitudinal movement, substantially as described.
