Nrrnn STATES HENRY VILKINSON, OF NEWBURG, NEW YORK.

IMPROVED DOOR AND WINDOW FASTENER.

To all whom it may concern 'transverse vertical section of the same. Figs.

3 and 4 are detached views of the double set of roller-bits for operating the bolts. Fig. 5 is a modification of the same.

Similar letters of reference in all the iigures indicate corresponding parts.

This invention consists in two double-armed lever-bits applied to a common revolving barrel, and operating in combination with springf1 ames, which carry the bolts and move in opposite directions in such a manner that by turning the barrel in either direction the bolts are drawn in simultaneously, and the door, window, or other device is unfastened, and by releasing the barrel the springs acting on the frames force the bolts out to the proper position for fastening the door or window.

The invention consists also in a sliding or oscillating latch, in combination with the reciprocating spring frames and bolts, in such a manner that by the action of said latch the frames are locked and the door or window can be securely fastened.

A represents a case made of sheet metal or other suitable material. which is mortised into the closing-edge of a door or window, and which may be provided with a anged faceplate, a, in the usual manner of mortised locks. The side plates, b b, of the caseA form the bearings for the revolving barrel c, which is provided with a square hole to admit the stem of the handle B, by means of which the barrel can be rotated in either direction. The barrel c carries twobits, d d', which are attached to the same on opposite sides, so that the same in turning the barrel act in opposite directions. Said bits are situated in diiferent places, and the bit d acts on a frame, e, while the bit d acts on a frame, c', and said frames are arranged within the case A, one above the other,

as clearly shown in Fig. 2 of the drawings. A spring, f, forces the frame e up, and a similar spring, j", forces the frame c down. The bits d d are double-armed, as clearly shown in Figs. l and 4, so that by turning the barrel in either direction the frame e is forced down and the frame c is forced up, and bolts g g', which are secured in the fram es e c, are caused to make a corresponding motion. The bolt g extends up through a mortise in the door or window, and when the frame e is in its highest position and the door or window is closed the head of said bolt catches in a socket, h, in the door or window frame O, and the bolt g extends down through a corresponding mortise in the door or window, and when theframe eis at its lowest position the head of the bolt catches in a suitable socket, h', in the sill of the door or in the lower bar of the windowframe, provided said door or window is closed. By turning the handle B in either direction, both bolts g g are drawn in simultaneously, and the door window can be opened. In closing the door or window the heads ofthe bolts slide up the inclined edges of the sockets h h and catch in them without the necessity of touching the handle. The friction between the ends ot' the bits d d and the sliding frames c c', and also the friction between the ends of the bolts and the edges of the sockets, is reduced by friction-rollers inserted into the ends 0f said bits and bolts.

If it is desired to lock the door or window so that it cannot be opened without the proper key, a latch, D, is made to catch in a recess, i, formed in the upper edge of the sliding frame e close below the lower edge of the frame c. This latch may either be suspended from a revolving barrel,j, as shown in Fig. l ofthe drawings, or it may be made to slide in and out, as shown in Fig. 5, and in the latter case a common bolt may be connected with it so that the latch and bolt move simultaneously, and by the bolt the door or window is locked in the ordinary manner.

The latch is operated by a suitable key, and if the bolts g g are fastened by means ot said latch the door or window cannot be opened until by inserting said key the latch has been turned back.

This fastening is applicable to doors of any description, and to such windows which are hung on hinges and known by the term of French windows. It is easily attached, it leaves the surfaces ofthe door or sash in good condition, and all its parts are so constructed that they are not liable to get out of order.

What l claim as new, and desire to secure by Letters Patent, is- The combination of the two doubled-headed armed lever-bits d df, the revolving barrel c, and the sliding,` plates e c with the bolts g g and the latch D, whereby a door can be secured at top and bottom, andthe bolts be withdrawn by a single turn of the knob, either right or left, substantially in the manner described and represented.
