Description

timidi @met i IIVIPIROV'-EMEIN'TIZ IN DOOR-FASTENERS.

The Schedule referred to in these Letters Patent and making pa'rt of the same.

To all 'whom it may concern:

Be it known that I, J 01m O. REILLEY, of the city of Baltimore, and State of Maryland, have invented a new and useful Improvement in Door-Fasteners; and I do hereby declare the following to be a full and correct description of the'sanie, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 represents a perspective front view.

Figure 2, a top view ofthe fastener in position.

Figure 3, a front View, showingthe fastener in position.`

Figure 4, a vertical section of the fastener, in the plane indicated by the lines .z-a: in figs. 2 and 3.

That any one skilled in the art may be y enabled to I make my door-fastener, I subjoin the following description and explanation of its workings.

The fastener consists of two separate parts of metal, shaped as in fig. 1, in which A represents the piece intended to be fastened to the casing of the door.

vThis isv provided with a shoulder, B, to rest against the -edge of the casing, a claw, G, to fasten into the inside of the casing, between it and the door, and upon the face, a dovetailed mortise, D, to receive the fastener E.

This fastener is composed of two pieces, F and G, but connected with a rivet, H, in such a manner as to allow the eccentrica]ly-pivoted button G to play freely upon its axis When the dovetailed tenon F is placed in position, it is prevented from falling through by a shoulder, P, shown iu igs. 2 and 4, Which-rests upon the upper. surface of the piece A, as in fig. 2.

Upon the convex face of the eccentric-button G is a sharp projection, I, which is intended to rest against the face of thedoor.

The projection'O, at the top of the tenon-F, answers to take hold of in attaching and detaching the fastener; also to fasten it by a string, through the hole, to the other part, thus keeping them together when not in use.

The hole M, in the Ipart A, serves to put a screw well to doors opening in either direction.

througb-into the casing, thus making permanent,.-

if desired. f

In order to better understand'the nature and workings of my invention, let us suppose thatK is the door, opening in the direction of the dotted lines a a,

Let L be the casing. Now, in order to apply the faste1 1er,'open the door, and placing the piece A against the casing, so that the shoulder B rests againstv the outside, and the claw C against the inside of the'same',

to open the door from the outside, prevents it being. I

done by the resistance presented by the button G, held in its place firmly by the piece A, which is itself reta-ined in position by the claws G, andthe pressure of the door itself, whichprevents'their being pulled out.

In addition to the superior advantages of simpli-v city, adaptability, and strength, possessed by my invention over others, my fastener is adapted equally By simply reversing the piece A, it'maybemade to fit either the right or left side of a door, thel tenon F being in either crise dropped into place'from above.

Having thus clearly explained my invention,

I claim .as new, and desire" to secure by Letters Patent-- I A door-fastener, composed of the parts F, Gr, and H, made and combined substantially in 'the manner described.v
