PPLICATION FILE Patented Mar. 27, 1917 ARTHUR 1?. LANE, OF DENVER, COLORADO 'SASHV-FASTENER.

Specification of Letters Patent.

Patented Mar. 27, 191 *7.

Application filed March 14, 1916. Serial No. 84,157.

, lar reference to that class of sash fasteners,

wherein a fastening element is carried by one of the sashes for engagement with the other sash.

' The principal object of the invention is to provide a fastener of the type mentioned vwhich will permit of adjusting either the upper or lower sash to any desired position, and which will operate to retain the sashes in either adjusted positions against movement of either in one direction.

Other important objects of the invention are to provide a fastener which is automatically operable; which will take up any play between the sashes, thereby preventing rattling; and which is so constructed as to permit ready assembly of its parts, the construction being such, however, as to prevent accidental loss of any part during use.

With the foregoing and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In the'drawings,

Figure 1 is a vertical section through a pair of sashes, showing the invention operatively associated therewith, and,

Fig. 2 is a fragmentary front elevation.

Referring to the drawings by numerals wherein is illustrated the preferred embodiment of my invention, 1 designates the upper sash and 2 the lower sash which are of the ordinary construction, and which are adapted to be arranged in a Window frame for operation in the ordinary manner.

The upper sash 1 includes a cross bar 3 carrying the frame strips 4 to which the panes of glass 5 are secured, while the lower sash 2 comprises an upper bar 6, frame strips 7 and panes 8.

The lower sash 2 has mounted upon the upper face of the bar 6 thereof a bracket 9 which includes a plate 10 secured to the bar by the screws 11 and has extending upwardly therefrom spaced ears 12. This bracket is arranged in alinement with any one of the frame strips 1 of the upper sash (as clearly shown in Fig. 2) or may be arranged in alinement with one of the side rails of the upper sash if desired.

Each .of the ears 12 has formed therein'a slot 18, and the slots of the two ears are arranged in alinement. These slots terminate centrally of the ears and open into the outer edges of the same, being arranged angulaily with respect to the ears and toward the upper sash 1, the said slots being arranged to extend slightly upwardly from their inner ends toward their outer openings, as is illustrated to advantage in Fig. 1 of the drawings.

A locking tongue 14 is adapted to be arranged for pivotal movement between the ears of the bracket 9. This tongue includes a plate of a thickness to be received snugly between the ears, and thisplate has extending from opposite sides thereof, adjacent one end, studs 15, which are of a size to be received snugly by the slots 13 with which they are to be engaged. The end of the tongue opposite to that carrying the studs 15 is eccentrically curved from an axis above the center of the studs 15 and is sufficiently broad and smooth to bind firmly and be locked securely against the frame strip 4 l without calling for effort, or applying undue pressure on the tongue. The length of the tongue is such that normally or when in locked position, it will incline upwardly toward the upper sash, so that its weight will hold it in action.

When the tongue is swung to a position as indicated by dotted lines in Fig. 1 of the drawings, it will be noted that either the upper or lower sash is freely movable, and

either may be adjusted to any desired po-' sition. By swinging the tongue to a position as indicated full lines in Fig. 1 of the drawings, however, the eccentrically curved end will engage with the frame of the upper sash and prevent downward movement of this sash relatively to the lower sash, and like-wise upward movement of the lower sash will be prevented. It will be noted further that upward movement of the upper sash is permitted, or downward movement of the lower sash, but the tongue will automatically operate to prevent movement of either of the sashes in an opposite direction. Where the sashes are loose within their frames so that one is permitted of outmoved therefrom and is prevented from being readily lost by reason of the angular disposition of the slots 13. A finger piece 17 projects from the tongue 14 to facilitate rocking the same.

As a further protection against the use of force in an attempt to 'open the Window from without, a spur 16 is formed at the top of the eccentric working end of the tongue 14 in position to be free from contact with the window under usual conditions of use, but when great efforts are made to raise or lower a locked window, the tongue 14 will be rocked downward so far under the strain that the spur 16 will enter the wood of the window and further secure them. i

From the foregoing description taken in connection with the accompanying drawings, it is thought that the construction and operation of the improved sash fastener will be understood, and while I have herein shown and described one specific embodiment of my invention, I do not wish to be limited thereto except for such limitations as the claim may impart.

I claim A sash fastener including a supporting bracket formed from a length of metal, the length of metal being bent to provide a U- shaped vertically extending member, the

opposite ends of the length of metal being bent and extended downwardly and lying against the vertical portions of the U-shaped member, said ends being then bent at right angles and extended laterally to provide securing means, and a window engaging member having trunnions thereon which are loosely extended through the vertical bars of the U-shaped member and the portion of the metal lying against the same, the securing means and the horizontal portion of the U-shaped member being in alinement.

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