UNITED starts PATENT rre ASAHEL GILBERT, JR., OF LOIVELL, MASSACHUSETTS.

SASH-FASTENER.

Specification of Letters Patent No. 13,491, dated August 28, 1855.

T0 all whom it may concern.'

Be it known that I, AsAHEL GILBERT, Jr., of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Sash-Fasteners for Vindows of Railway-.Cars and for All other Kinds of Vindows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l, is a front elevation of a window sash and its supporting frame, having my improvements attached. Fig. 2 is a vertical section through w and Fig. 3 is a horizontal section through y, e.

Similar letters of reference in each of the several figures, indicate similar parts.

A, is the window frame that supports the sash, and in which, the sash slides up and down.

B, is the sash.

C, C, is the knob or handle by which the sash is raised and lowered. This knob is made of two parts which are connected together and to the face plate D by a hinge joint.

s, s, are two short arms that extend one from each half C, of the handle or knob. When the two halves of the knob are pressed together, these arms s s, shut by each other like the blades of a pair of scissors. Fastened to the extremity of each of these arms s, s, is a small connecting wire E, E. These wires extend out horizontally, one to each edge of the sash, through a channel made for the purpose in a bar of the sash, and fastened to these extremities are the bolts F, F. These bolts are situated in holes made for them, one in each edge of the sash; and the end of each projects therefrom a sutlicient length, to enter the holes G G, G, &c., made in the window frame.

H, I-I, are spiral springs, which are placed between the inner ends of the bolts and the inner ends of the holes made to receive them, for the purpose of forcing the bolts into the holes G, G, G, te., in the frame, and thus secure the sash in position.

Having thus described the various parts of which my invention is composed, I will proceed to describe their operation.

If the sash is down, and we wish to raise it; all it is necessary to do, is to press the two parts of the knob together with the thumb and linger, which will draw the bolts and liberate the sash; then lift on the knob until the sash is raised to its full height, and when you let go the handle, the springs will force out the bolts vinto the holes G, G, &c., and thus fasten the sash in its elevated position.

It is evident that the window may be fastened at any height by providing a sulicient number of holes in the frame.

Vhat I claim is- The hinged cross-bars C, C, having splitknob handles, serving to disengage the r fastening on both sides of the sash, and to raise and lower the sash, substantially as herein described.

In witness whereof, I have hereunto set my signature this twelfth day of May A. D. 1855.
