WINDOW-FASTENER.

.'JTCIFICAIION formin art of Letters Patent No. 311,765, dated Februar S, 18185.

f5 p Y Appliratinn filed March 10, 1F84. (No nimle.)

To all whom, t may concern:

Beit known that l. GEORGE H. Kammer-r ER., a citizen ot' the United States, residing at Columbus, in the county ofFranklin and State of Ohio, have invented certain new and useful Improvements in VindowFasteners, of which the following is a specification, reference being had therein to the accompanying` drawings, in which- Figure l is a central vertical section of a sash-fastener constructed in accordance with iny invention. Fig. 2 is a similar View of a modification, in which the lower sash is represented as slightly raised. Fig. 3 is a plan of Fig. 2. Fig. 4 shows the fasteners sheath open at the top.

Like letters refer to like parts in all the ligures.

The object of my invention is to provide a sash holder and fastener which, while secured to the n1eeting-rails,shall be capable of secu rel y locking the sashes when closed, and also when partly open, and to firmly draw the meetingrails thereof against each other in the act of locking the saine, and to hold them in close contact with each other when locked.

Ot-l1er.objects and advantages will appear in the following description, and the novel features of my invention will be specifically set forth in the claim.

A represents the inner or lower sash, and B the outer or upper sash, and a b the meetingrails of the same, respectively.

Upon the meeting-rail b, I secure, in any suitable manner, a stud or standard, C, having upon its inner surface a series of teeth, c, having their lower edge horizontal, and a V- shaped hook, c', Fig. 1, projecting bodily beyond the inner face of' the meeting-rail, and to provide for the passage of the meeting-rail a said rail has formed therein a se1ni-conical groove at a4. f

Upon the meeting-rail c, I secure a plate, a', having` a depending hook, c2, adapted to cooperate with the hook c', whereby when the sashes are closed the inclined surfaces of the two hooks c c act to draw the meeting-rails firmly against each other. The inner end of the plate a is formed so that the latch may take thereunder, the upper inner edge of the rail a being cut away for the reception of the point of the latch, if desired. The plate c is rovided with a vertical bracket c )erfop 7 7 1 rated for the pivot-a1 support of a loeking-lever, D, thereon and slotted for the passage of a portion of said lever therethrough. This bracket may be of any suitable design and configuration for thefunctions stated, and may be extended so as to cover from' sight the teeth of the standard C; or it may be made to enr brace the standard, for the purpose hereinafter described. -The lever D has near one end an arm, d, through which its pivot passes, and above the pivot the said arrn has a projection to form a stop, d', which, abutting against the bracket c3, prevents any possibility of the free end of the lever being thrown against the glass b`2 of the sash or of remaining in a vertical position.

d is a latch pivotal] y secured to the free end of the lever D, whereby it niay be caused to take under the plate u', and thus lock the lever in a depressed position, with its inner end projected within the bracket a3, so as to take into the teeth of the standard C.

The above-described fastener is adapted for use upon sashes having cross-mullions B', but with windows having only two or four lights.

I prefer to construct the fastener as shown in Figs. 2 and 4, in which I have illustrated a simple construction which involves the use of the bracket a, wherein it is made to embrace the standard C, having its side c slightly inclined toward the apex, as before stated, inl which case the bore of the bracket is made conical at a2, and constitutes a sheath either with an open top or closed, as shown. This construction, in connection with a tapering rear or outer side or wall, c', of or upon the standard C, serves, in the act of closing the window, to firmly draw the meeting rails against each other. In this modification the plate a', hooks c a2, and latch 13(shown in Fig. l) are dispensed with, as is also the groove c* in the rail u, the plate a being projected beyond the plane ofthe window-franie partingstri p E, and also beyond the outer face of' the rail a, so as to forni a close jointwith the base of the standard C.

In the construction shown in Fig. 1 it will be seen that the sheath or bracket a3 and the lever D are adapted to pass any cross-mullions of the upper sash,which is not the case in the construction shown in Figs. 2, 3, and 4, which IOO is designed more especially for sash with largersized glass; but the use of a rateheted standard upon the meeting-rail ofthe upper sash and an engaging-lever upon the lower sash is the same in either figure. It will be seen that by elevating the free end of the lever D its opposite end is withdrawn from the teeth of the standard C, and that the lower sash may be raised to any desired height, and provided the upper rail thereof is not elevated above the standard, rod, or stud @,whatever may be the length of the latter, the sashes maybe locked and rmly held togetherl in said partially raised or open condition; furthermore, in eases where, by reason of light weights or other eauses, the upper sash settles below its normal position, it may be raised by means of the lower sash and thelever thereon to its normal I position, and said lower sash may afterward be depressed and securely looked, as before described.

Havingr fully described my invention I claim- The combination of upper sash-rail, b, provided with a toothed standard having an inelined wall or side, as c', with a bracket having` an inclined side or wall, as a?, adapted to eo-operate with the inclined wall c', and a lever adapted to take into the teeth of the standard, substantially as speeiiied.

In testimony whereof I affix my signature in presence of two witnesses.
