WINDOW-FASTEN ER.

SPECIFICATION forming part of Letters Patent No.1341,745, dated May l1, 1.886.

Appication filed August 2l, 1885. Seri-.1l No. 174,862. (Model.)

To rtf/Z w72 om, may concern:

A3e it known that I, PETER GILLrs, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massa` chusetts, have invented certain new and useful Improvements in Fastenings for Windows; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its objectan automatic window-sash fastener, which will also serve to hold the two parts of the window firmly, so vas to prevent the motion ofthe same, commonly called rattling In the drawings I have shown in Figure l a perspective view of my'invention, looking from without; in Fig. 2 a plan view of my invention; in Fig. 8 a sectional view ofthe same on the line x a', Fig. 2; and in Fig. 4 a sectional view of the same on the line yy, Fig. 2.

a is the part of my fastener to be attached to the upper window-sash. and b the part to be attached tothe lower sash. The part a has the catch c, moving on the pin f in the slot d in the raised parte. 'The upper part of the catch c is bentin the manner shown in Fig. 2, so that it can easily be turned down by the thumb when Athe window is to be opened. This catch fits into the part e for the purpose of fastening the sashes.

71. is a wedge-shaped piece attached tothe forward part of a, or forming one piece with it, and tting into a wedge-shaped slot, i, in the part b, as shown in Fig. 4. The forward end of part e fits into the recess k in the part b, which recess is of such shape as to permit the forward end of part e to tightly tit therein, so as to allow no sidewise motion of the sashes upon each other, the upper part of the part I) projecting beyond the front side of the sash to which it is attached, as shown in Fig. 4. It will be seen that when the window is closed the catch acts automatically and securely fastens the window, While the wedgeshaped piece h tits into the corresponding slot, t', and prevents all motion of the window in or out, and the part e, iitting into the recess la, prevents all sidewise motion ofthe sashes. When the window is to be opened, the catch c is to be turned down by the hand. It is obvious that it will be impossible to open this window from lar instrument between the sash, or in any way except by breaking the glass, so as to turn the tion or rattling of the window is effectually prevented.

Vhat I claim, and desi-re to secure by Letters Patent, is

The automatic windowsash fastener, consisting of the parts a and b, to be attached, respectively, to the two parts of the window sash, the part a having the wedge-shaped piece h, adapted to fit into a corresponding slot, 1i, in the part b, and the forward end or the part a adapted to fit into the recess k in the part b, and the catch e, moving in the slot din the part e upon the pin f, substantially as and for the purpose above described.
