TO ALL WHOM IT, MAY CONGERN: l

Be it known that I, ROBERT H'TTON, of Brooklyn, in the county of Kings, and State of New York, have invented a new and improved Sash Fastening; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same,reference boing had to the accompanying drawings, -forming part of this specification, in which- Figure 1 :san inner side view o f a portion of a window frame and sash, having my invention applied to it.

Figure 2, a vertical section of the same, taken in the line z ze, fig. 1.

Similar letters of reference indicate lik-e parts.

This invention relates to a new and improved fastening rfor window sashes, whereby the latter may be supported at any desired height. The invention consists of a wedge or key tted in a socket attached to the window frame, and interposed between one of the side pieces of the sash and a frictionroller in the-socket, as hereinafter full'y shown and described, whereby a very simple and eicient sash fastening is obtained, onewhich will afford an easy manipulation of the sash, not liable to become deranged by use, and which may be manufacturedvat a small cost.

A represents a portion of a window frame, and B a portion of a sash, fitted in the frame so as to rise and fall freely, and C is a metal socket, secured to the frame A, at the inner edge of one of its side pieces, a, so that the inner side of the socket, which's open, will be opposite one of the side pieces, b, of the sash. D is a wedge or key, which is iitted vertically in the socket C, and has its rear side bearing against a friction-roller, E, in the socket, the other side of which is serrated, being in contact withthe side piece b, of the sash, (see tig. 2.) The roller E is tted in the lower' part of the socket, and the wedge or key D has a rod, F, attached to its upper end, said rod passing up through an opening iin the top of the socket, and having a horizontal thumbpiece, c, on its upper end. From the above description, it will be seen that the sash may be raised without any direct manipulation of the wedge or key, as thek upward movement of thesash has a tendency to raise the wedge or key, but the sash cannot descend, and willbe retained 'at any desired point, as the gravity of the sash downward has a tendency to cause the wedge or key to bind between the roller E and the side piece b of the sash. In order, therefore, to lower the sash, the wedge or key D must be pushed upward, which is done by pressing the thumb upward against the thumb-piece-c, and in case the wedge or key should become tightly bound between the friction-roller and sash, the latter may be raised a triiie, to loosen it, and the thumb then applied to the thumb-piece c, to hold the wedge or key upwhile the sash descends. This sash fastening may be constructed at a small cost, and readily applied by any one. There are no parts liable tor getout of order or become deranged by use, nor can it be materially' aiiected by wear. The socket, wedge or key, and the friction-roller are designed to be of metal.

i What I claim as new, and desire to secure by Letters Patent, ifi--` A window-,sash fastening, composed of a socket C, provided with a friction-roller E, or its equivalent, and a wedge or key D, applied to a window frame, 'and in such a relative position with the sash B, to operate in` the 'manner substantially as and for the purpose herein set forth. l
