Roche, Hartford, Conn. Application September 12, 1934, Serial No. 743,700 3 Claims. My invention relates to improvements in win dow sash holders which are adapted to hold a sash in any desired position in the window frame without requiring the use of the usual counter 0 weights. An object of my invention is to provide a holder of the class described which is economical to manufacture, easy to install and highly ei?cient 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 en 15 gagement 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 su?icient to- support the weight of said sash. Further objects of my invention will be clearly 20 understood from the following description and from the accompanying drawing in which: Figure 1 is a front view in elevation of a win dow frame and sash partly broken away to illus 25 trate 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 de notes a window frame of usual construction, 6 an upper, and l a lower window sash each having 35 formed therein recesses: 8 in the side rail thereof within which recesses my improved holder is con tained. 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 ?tted loosely in the roller l2 and in the 45 slots I I so that, when the holder is to be assem bled, 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 50 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 55 in said holder by the side walls of the recesses 8, (Cl. 292-75) which recesses are of a width just slightly greater than the width of the holder frame, thus providing simple and inexpensive means of as sembling 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 rela tion to the roller. 15 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 pro vides a convenient and simple manner for attach ing the holder. 20 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 en gagement with the window frame. When the 25 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 30 sash in any desired position. It is pointed out that in some cases where the window sash is of a particularly heavy construc tion, the friction between the sash and the frame alone will not be sufficient to retain the sash in its 35 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. 40 I claim: 1. A window sash holder of the character de scribed comprising a U-shaped frame having an elongated base portion which is straight in cross section, side members bent upwardly from said 45 base portion and integral therewith, a roller slid ably 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 50 portion for applying both lateral yielding pres sure to said roller and frictional resistance against rotation thereof. 2. A holder of the character described com prising a U-shaped frame having an elongated 55 2 2,030,269 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 slid ing contact with the base of said frame and the center portion thereof in contact with the pe riphery of said roller to both force said roller out wardly and to apply a frictional braking action on the periphery thereof against its rotation. 3. In combination with a sash having an open members extending upwardly from said base por tion and integral therewith, a roller movably mounted in said holder between said side mem bers, 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. recess, a holder comprising a channelled frame having a substantially straight base portion, side 10 THOMAS T.
