Application September 12, 1934, Serial No. 743,700

3 Claims.

My invention relates to improvements in window sash holders which are adapted to hold a sash in any desired position in the window frame without requiring the use of the usual counterweights.

An object of my invention is to provide a holder of the class described which is economical tomanufacture, easy to install and highly eificient in its operation.

A further object of my invention is to provide such a holder which is adapted to hold the sash in frictional engagement with the window frame, by means of a roller which has a spring member co-operating therewith to force said roller in engagement with the said frame and to apply a braking action to said roller against the rotation thereof which, in addition to the friction between the sash and the frame, is sufiicient tosupport the weight of said sash.

Further objects of my invention will be clearly understood from the following description and from the accompanying drawing in which:

Figure 1 is a front view in elevation of a window frame and sash partly broken away to illustrate the application of my invention.

Figure 2 is a front view in central vertical section, on an enlarged scale, showing a portion of a window sash and frame and my improved holder attached thereto.

Figure 3 is a side view of the holder in elevation.

Figure 4 is a top view of said holder.

As shown in the drawing, the numeral 5 denotes a window frame of usual construction, 6 an upper, and l a lower window sash each having formed therein recesses: 8 in the side rail thereof within which recesses my improved holder is contained.

The said holder comprises a U-shaped frame having a base 9, and side members it} in which slots H are provided. A roller i2 is mounted between the side members it and positioned therein by means of a shaft 63 extending thru. said roller and projecting into said slots. This shaft is fitted loosely in the roller l2 and in the slots I I so that, when the holder is to be assembled, it is simply necessary to place the spring M in position and the roller it against the curved portion l5 and forced inwardly. The shaft i3 is then inserted thru one of the slots H, to the position shown in the drawing, and pressure on the roller is released causing the shaft to be forced against the end of the slots. When the holder is in position within the recesses 8 in the sash, the shaft will be retained against lateral movement in said holder by the side walls of the recesses 8,

which recesses are of a width just slightly greater than the width of the holder frame, thus providing simple and inexpensive means of assembling the holder and retaining the shaft in its proper position. A friction and thrust spring 5 It is positioned between the said roller and the bottom Q of the frame. This spring has a curved portion l5 conforming with the periphery of the roller and the said spring acts: to press the roller outwardly in engagement with the window frame 10 5 and also, by means of such pressure, to apply a braking action against the rotation of the roller. The said curved portion 55 also acts to retain the spring member in its proper position with relation to the roller.

My improved holder is attached to the sash by means of screws it which project thru screw holes H in the bottom of the frame. This provides a convenient and simple manner for attaching the holder.

In the operation of my improved holder, the spring member it acts to force the roller i2 against the frame 5. In this manner the opposite side of the window sash is held in frictional engagement with the window frame. When the 5 sash is moved to any desired position within the window frame, the friction between the opposite side of the sash and the frame and the friction applied to the roller by the curved portion E5 of the spring member M is sufficient to retain the sash in any desired position.

It is pointed out that in some cases where the window sash is of a particularly heavy construction, the friction between the sash and the frame alone will not be sufficient to retain the sash in its desired position but that with the addition of the braking action applied to the roller i2, sufficient friction is provided on both sides of the sash against the window frame to retain a sash of any practical weight in any desired position.

I claim:

1. A window sash holder of the character described comprising a U-shaped frame having an elongated base portion which is straight in cross section, side members bent upwardly from said base portion and integral therewith, a roller slidably mounted in said side members for holding the sash in frictional engagement with a window frame and single means consisting of a spring member having its ends slidable on the said base portion for applying both lateral yielding pressure to said roller and frictional resistance against rotation thereof.

2. A holder of the character described comprising a U-shaped frame having an elongated base portion which is straight in cross section, a roller movably mounted in said frame, and a W-shaped spring member having its ends in sliding contact with the base of said frame and the center portion thereof in contact with the periphery of said roller to both force said roller outwardly and to apply a frictional braking action on the periphery thereof against its rotation.

3. In combination with a sash having an open recess, a holder comprising a channelled frame having a substantially straight base portion, side members extending upwardly from said base portion and integral therewith, a roller movably mounted in said holder between said side members, a spring located between said roller and said base portion and in contact with the periphery of said roller and the surface of said base portion; said holder being secured to said sash with the base portion thereof against the bottom of said recess and secured thereto.
