SASH-FASTENER.

Specification forming part of Letters Patent No. 49., 159, dated August 1, 1865.

To all whom it 'may concern:

Be it known that I, A. H. ROWE, ot' Hartford, in the county oi' Hartford and State oi' Connecticut, have invented a new and Improved Sash-Fastener; and I do hereby declareV that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying dra-wings, forming part ot' this specilication, in Which- Figure l represents an inside view of my invention. Fig.2 is avertical central section of the same. Fig. 3 is a plan or face view ofthe same.

Similar letters of reference indicate like parts.

This invention consists in a revolving slotted cam arranged in a circular case, in combination with a radially-sliding spring-bolt, in

such a manner that when the device is applied to a sash by turning the cam in one direction the spring-bolt is drawn in and the sash unfastened, allowing it to move up or down. and by releasing the cani the bolt is allowed to drop into suitable sockets made in the side of the window-frame at suitable intervals, and in this position it is locked by the cam, and the possibility of a spontaneous unfastening ofthe sash is avoided.

A represents a circular case, made of metal or other suitable material, and provided with a suitable ange, a, and holes b, so that it can be readily secured to the jamb ot'a sash, as shown in Fig. 3 of the drawings.

Through the case A, in a diametrical direction, passes the bolt B, being guided at both ends by holes in the sides ot' the case, and in the center by the screw b', which passes through a slot, c, in the body ot' the bolt, as `clearly shown in Fig. l of the drawings. A spiral spring, d, Wound round the shank ot' the bolt has a tendency'to force the same out in the direction of the arrow marked near it in Fig. l.

In order to force the holt back a revolving cam, G, is applied, as shown. This carn turns on thc central screw, b', and it is provided with a slot, e, which catches over a pin, f, projecting from the headof the bolt, as shown in Fig. 2. The cam is operated by a handle, h, which prpjects through a segmental slot, g, in the case, and which is secured in an arm, t', ex-

tendingfrom the cam C. Said cam is so shaped that when the bolt is allowed to follow the action of the spring d it is `lockedby said cam bearing against the pin f, and by these means the bolt is prevented from receding spontaneously. By turning the handle h in the slot g the cam acts on the pin f, so thatthebolt is forced back against the action of the spring d.

When the case A is secu`red to asash, `asshown in Fig. 3 of the drawings, and the bolt drops into holes in the side strip of the frame, the sash is locked, and the bolt cannot recede and unf asten the sash until the camG is turned. By taking hold of the handle l1l and turning it` in the direction of the arrow` marked near it in Fig. 3 the bolt is withdrawn, and at the same time by pressing against the handlethe sash can be .raised to any desired position. On releasing the handle the bolt is forced out by the action of the spring, and when itcomes opposite a socket in the strip itdrops in and relocks the sash.

This sash-fastening is intended particularly A. H. ROWE.
