Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed June 13, 1911. Serial No. 632,903.

To all whom it may concern:

Be it known that 1, WILLIAM S. Sonncitizen of the United States, res1d- BURY, a 0 ing at Sedro Woolley, 1n the county of Skagit, State of Washington, have lnvented certain new and useful Improvements in Roller-Bearing Sash-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window sashes, and particularly one so constructed that the use of pulleys and sash balances are eliminated, but at the same time the sashes may be raised and lowered in an easy manner and held in their adjusted open position.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :-Figure 1 is a front elevation of a sash and frame, the side sec tions being partly broken away. Fig. 2 is an end view of the sashes, one side of the same being presented. Fig. 3 is a sectional view on line 3-3 of Fig. 1, when the lower sash is in its raised position.

Referring to the drawing, the numeral 1 designates a window frame having guide ways 2 provided, and in which the upper and lower sashes 3 and 4, respectively, are slidably mounted.

The lower sash i has its side rails provided in their outer faces with channels 5, the channel in the left rail being slightly deeper at its upper end than at its lower end and is narrowed slightly at its lower end. The channel formed in the right rail of the lower sash is formed in a manner reversely to that in the left rail, the object of this formation will be hereinafter described.

Formed in the side rails of the upper sash are channels 6, the channel in the left rail being wider and deeper at its lower end than at its upper end. The channel formed in the right rail is deeper and wider at its upper end than at its lower end.

7 hen the sash and frame are in their assembled position rubber balls 7 are placed in the channels formed in the upper and lower sashes so that they will be in yielding contact with the face of the guide ways 2. From this construction it will be seen that when it is desired to raise the lower sash, the balls 7 having been previously placed within the upper ends of the channels 5, the upward movement of the sash will cause the balls to travel in a downward direction, the ball in the channel of the left rail traveling downwardly and into the narrowed lower portion of the channel, which travel causes the ball therein to be compressed and projected outwardly to frictionally hold the sash in its raised position. The ball in the channel in the right rail travels downwardly from the shallow and narrowed portion of the channel to the widened and deeper lowered portion, so that the sash will be held from one side or the other when in its different raised positions.

The operation of the balls in the channels of the upper sash is the same as that of the lower sash, with the exception that the balls are placed, when assembling the frame and sash, in the lower ends of the channels 6 formed in the side rails of the sash.

it should be noted that the balls 7 are constructed preferably from rubber or other resilient material, and upon the operation of the window sash they will be compressed and forced to the smaller ends of the channels in which they are located, and owing to their resilient nature will frictionally engage the window frame permitting the sashes to be raised and lowered by force, and holding the same in their various adjusted positions by their resiliency which counteracts the weight of the sashes and prevents any undesired movement when the same has been adjusted.

It will be seen that owing to the tapered arrangement of the channels 5 and 6, one side of the window frame will at all times be frictionally engaged by the balls.

What is claimed, is v In a Window construction, the

tion with a frame; of a sliding sash therein having longitudinal channels in the outer 5 faces of the stiles thereof, said channels being Wider and deeper at one end other the Wider and deeper ends of said channels being disposed at opposit the latter, and

posed in said channels adapted to project 10 beyond the outer faces of the stiles for enthe frame.

whereof, I afix my signae of tWo Witnesses.
