Patented Dec. 13, 1949 UNITED STATES PATENT OFFICE 3 Claims.

The present invention relates to sash holders and more particularly to a device for retaining a vertically slidable window sash in a given selected elevated position.

The primary objects of the instant invention are to provide a device of the general character above indicated, the use of which dispenses with the necessity of employing sash weights; to provide such a device, the use of which enables one to raise and lower a window sash with ease and without undue exertion; to provide such a device which is highly eiicient in its intended use; to provide such a device which is simple yet rugged and sturdy in construction; to provide such a device which may be readily and conveniently installed and which is universally adaptable for use in any vertically slidable window sash; and, to provide such a device which is reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:

Figure 1 is a fragmentary rear elevational view of a window frame and sash and the device of the instant invention secured to the sash, the view being on line I-I of Figure 2;

Figure 2 is a sectional view on line 2-2 of Figure 1;

Figure 3 is a perspective View of the device; and

Figure 4 is an enlarged sectional view on line 4--4 of Figure 3.

Referring then to the drawings wherein like parts of the device shown and its environmental structure are designated by the same numerals in the several views, a window sash I and its pane |09 vertically slidable in the casing or frame II may be retained in a given selected elevated position by means of a pair of devices of the instant invention each of which comprises oppositely disposed elongated springable members I2, I3 of any suitable material such as spring metal whose opposite ends are curled for maintaining them one adjacent the other, all as best shown in Figures 1 and 3.

The member I3 is provided with a well I4 on its inner surface intermediate its ends whereas the member I2 is provided with an aperture I5 in registration with the well Ill and a ball bearing l interposed between the members I2, I3 is seated in the well I4 and has a portion thereof projecting through the aperture i5.

The opposite sides of the window frame or casing II are each provided with a forward vertically disposed elongated sash guide I'I and with a rearward vertically disposed elongated channel bar sash guide I8 in spaced parallel relationship to its companion sash guide Il, the lengths of the legs I9 of each channel bar I8 being here shown as inwardly embossed and flanged inwardly toward each other, all as best seen in Figure 2.

A bracket generally designated 20 provided with a pair of spaced screw receiving apertures 2I having a flanged intermediate portion 22 and an outwardly flanged end portion 23 provided with a partial circular cut out opening 24 adjacent its outer end, is secured to each upper outer vertical length of the window sash I0 by screws 25, all as best viewed in Figures 1 and 2.

The curled ends of the springable members I2, I3 are seated within the cut out opening 24 of the bracket 20 and from which they are pivotally suspended, all as best shown in Figures 1-3, their depending lengths riding within the channel bar I8 during the raising and lowering movement of the window sash I0.

The opposite curled ends of the springable member I2 tensionally bear against the inwardly hanged portions of the legs I 9 of the channel bar I8 and that portion of the ball bearing I6 which projects through the aperture I5 of the springable member I2 tensionally bears against the inner surface length of the medial portion of the channel bar I8 during the raising and lowering of the window sash Ill, all as best shown in Figures 1 and 2, the springable members thus effecting a tensioned retention of the sash in any given selected elevated position.

It will thus be seen that the sash holder herein shown and described dispenses with the necessity of employing sash weights, that the use of a pair of such sash holders enables one to raise and lower the sash with ease and without undue exertion, that the device is highly elicient in its intended use, that the device is simple yet rugged and sturdy in construction and may be readily and conveniently installed, is universally adaptable for use in any vertically slidable window sash and is reasonably economical in manufacture.

While but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined in the following claims.

I claim:

1. A window sash holder comprising a pair of bowed oppositely disposed elongated springable members whose opposite ends are secured together for maintaining them one adjacent the other, a well on the inner surface of one member intermediate its ends, said other member having an aperture in registration with the well, a ball bearing seated in the Well and having a portion thereof projecting through the aperture, and means secured to the members for securing the window sash holder to a Window sash.

2. A window sash holder comprising a pair of bowed oppositelvdispo'sed elongated 'ispringable members 1Whose opposite ends are secured together for maintaining them one adjacent the other, a Well on the inner surface of one member intermediate its ends, said other member having an aperture in registration with the Well,

a ball bearing seated in the well'and having a portion thereof projecting through the aperture, and a bracket secured to oneend ofthe members for securing the Window sash holder to a window sash.

kA Window sash holder comprising an elongatedtrackadapted to be vertically secured to a Wird'vv 'frame 'adj acent'a vertically movable Window sash, a bracket adapted to be secured to the Window sash, a pair of bowed oppositely disposed elongated springable members whose opposite ends are secured together for maintaining them one adjacent the other, a well on the inner surface of one member intermediate its ends, said other member having an aperture in registration With the Well and a ball bearing seated in the Well and having a portion thereof projectingrthrou'gh the aperture, 'said pairof springable Amembersbeing secured to said bracket and dependingly slidable on a length of the track.
