.Z '0 all whom it may concern:

Be it known that I, Jorm'll. GiBsoN, a citizen of the United States, residing at Bruin, in the county of Butler and State of Pennsylvania, have invented a new and use ful VVindow-Sash Holder, of which the following is a specification.

The present invention relates to window sash holders the object being to provide a window sash holder whirh is used in connection with a sliding sash and which will retain the same in any adjusted position.

A second object of the invention is to provide a window sash holder which will offectively retain the sash in raised position and which will at the same time prevent rattling of the sash.

A further general object of the invention is to provide a sash holder which is applicable to any vertically movable sash and which will dispense with weights, pulleys and cords that are now commonly used.

It is another important object to provide a window sash holder which includes a spring urged housing in which is journaled a roller for engagement with the window frame to retain the window sash in adjusted position, and means associated with the roller and housing to prevent the roller from rotating in a counter-clockwise direction upon the lowering of the sash.

Still. another object of the invention resides in the provision of a spring actuated roller which frictionally engages the side rail. of the window frame to retain the sash in adjusted position, a novel mounting being provided for the roller which not only serves as a mounting for the roller but as an abutment for the spring used in the con- Struction of the device.

An additional general object of the invention resides in the provision of a sash holder having the above characteristics, which is simple in construction, which con sists of few parts and which may be manufactured and placed on the market at a minimum cost.

With the above and other objects and advantages in mind, the invention consists of the combinations of elements, constructions and formations, arrangement of parts, and general assemblage, the details of which will be hereinafter enlarged upon and recited in the appended claim, one embodiment of the invention being illustrated in the accompapying drawings, wherein gure 1 is a sectional view of a window sash having my improved sash holder mounted therein, parts being broken away;

Fig. 2 is a fragmentarysectional view of one of the side bars of a window frame and sash showing the sash holder associated therewith Fig. 3 is a fragmentary end elevation of the sash and showing the sash fastener in end elevation; and

Fig. 4 is a longitudinal vertical sectional view of the sash fastener removed.

llcferring in detail to the drawings, the numeral 5 designates the vertically movable sash while Gdesignates one of the side rails of the same, the inner face of the side rail of the sash 5 being provided with a rectangular recess 7. A cylindrical recess 8 is also provided in this rail 6 rearwardly of the recess 7. The opposed vertical faces of the side walls of the recess 7 are provided with parallel longitudinal grooves 10.

Adapted for longitudinal movement in the recess 7 and insertihly accommodated therein is a substantially rectangular housing or plunger 11 which is open at one side to receive a roller 12 mounted upon a shaft 7 13 in the side walls of the casing 11, the ends of the shaft being slidably engaged in the longitudinal grooves 10. The rear end of the housing 11 is formed with a thickened part, the inner surface of which is curved longitudinally, as indicated at 13. One or more rollers lt are positioned on this inner curved surface and are adapted to bind against the roller 12 and the rear end of this curved wall should the roller start to rotate in a counter-clockwise direction. The rear face of the casing 11 is formed with a rearwardly extending projection 14. A disk 15 having a central aperture is mounted upon a screw 15, whichis secured in and extends rearwardly of the projection 14:. .This screw is equipped at its free end with an enlarged end 17 which at times abuts with the. bottom of the recess in the sash rail and prevents undue inward movement of the housing 11. A coil spring 16 encircles the projection 14 and bears against the disk and normally urges the same toward the head 17. The disk 15 normally bears against the bottom of the circular recess in the rail 5.

posite end of the coil spring.

The embodiment of he invention herein I shown and described is considered the pre- 7 'ferredforim but it is to be understood that the same is susceptible to variousmodifications, and that my'limits of such modlfication are governed onlyby what is claimed.

What is claimed is':-+

In a sash fastener a vertically movable sash having a recess 1n one side thereof, a

housing s-lidable in the recess, the rear wall and the bottom wall of the housing being formed with a thickened part, the surface of which being longitudinally curved, aroller journaled in the housing and movable over one rail of the window frame, rollersmovable over the curved surface and adapted to vbind against the first-mentioned roller to lock the same against rotation upon the lowering of the sash,rand expansible means urging the housing toward the sash frame.

In testimony that I claim the, foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses;
