JAMES H. BOYE AND ERIK S. HAGEN, OF CHICAGO, ILLINOIS, ASSIGNORS TO JAMES H. BOYE MANUFACTURING COMIPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

Application filed June 22, 1916.

To all whom it may concern Be it known that we, JAMES 11. Born and ERIK S. HAGEN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Holding Devices, of which the following is a specification.

This invention relates to sash-holding or supporting devices of that general type wherein a roller is carried by one of the relatively sliding parts comprising the sash and its guide groove and engages the vertical wall of the other part, the roller being so controlled that it may turn freely during the upward movement of the sash but is locked against rotation in the opposite direction during the downward movement of the sash, and is further provided with spring means for forcing it against the vertical surface over which it rides with sufficient friction to prevent the sash from dropping under its own weight, but permitting the sash to be readily drawn downwardly. Sash holders or supports of this general character are designed to do away with the usual sashbalancing weights, but, of course, lack one function of the latter which is to counterbalance the weight of the sash during the sash-lifting movement.

The principal object of our invention is to provide an improved and simplified sashholder or support of the characterspecified which shall be economical to manufacture, easy to apply, shall not require the mortising of either the sash or the frame for its application, and shall be easily and conveniently adjustable to vary the spring pressure of the roller as required.

Other objects and advantages of the invention will be apparent as the same becomes better understood by reference to the following detail description taken in connection with the accompanying drawing wherein we have illustrated a practical and preferred embodiment of our invention which has been found to efficiently accomplish the stated purposes and objects thereof.

Referring to the drawings, Figure 1 is a fragmentary elevation of a window frame and sash illustrating the application of our invention, the guide-groove of the lower sash appearing in section; Fig. 2 is a top plan vlew of the lower sash to which our im- Specification of Letters Patent.

proved-holder is applied, the guide-groove and upper portion of the holder appearing in horizontal section; Fig. 3 is a longitudinal section as seen on the line 33 of Fig. 2, and Fig. 4 is a sectional view taken on the line H of Fig. 8.

Referring to the drawing, 6 designates the upper horizontal sash rail of a lower window sash, and 7 designates the usual vertical groove or channel in which the vertical side of the sash is guided.

8 designates a channel-shaped casing or housing that rests upon the upper sash rail 6 and is preferably secured in place by a cover member 9 having vertical walls 10 that overlap the side walls of the casing 8 and terminate in horizontally disposed flanges 11, through holes in which fastening screws 12 enter the sash rail 6. The casing 8 is provided at its end adjacent to the guide groove 7 with a pair of parallel upstanding walls 13 that are preferably oontinuations of the side walls of the casing S; and through the upper end of the walls 18 is passed a pin 14-, on which latter, and between the walls 13, is pivotally suspended a roller-supporting hanger comprising parallel side walls 15 and a connecting rear wall 16. In and between the forward portions of the side walls 15 of this hanger is j ournaled a roller 17. Lying within the casing 8 is a coil spring 18, the forward end of which abuts against the lower end of the rear wall 16 of the roller hanger, while its rear end is engaged, through the intermediary of a swivel cap 19 with an adjusting screw 20 that passes through the rear wall of the casing 8 and has threaded engagement with a plate or block 21 just inside said rear wall. Preferably, and as herein shown, the extent of forward swing of the roller and its support under the impulse of the spring 18 is limited by a lug 22 struck inwardly from one of the side walls 13 of the casing and adapted to engage with the lower edge of one of the side walls 15 of the roller hanger. Between the periphery of the roller 17 and the rear wall 16 is interposed a roller 2", which, by reason of the fact that said periphery and rear walls 16 are upwardly di vergent and downwardly convergent, as clearly shown in Fig. 3, operates to permit free rotation of the roller 17 in a counterclockwise direction, viewing Fig. 3, but acts as a look, after the fashion of a roller clutch, to prevent the turning of the roller 17 in the reverse or clockwise direction.

The device, constructed as shown and described, is mounted on the sash rail 6 in the manner clearly shown in Fig. 1, with the roller 17 in engagement with the bottom wall of the guide groove 7. The adjusting screw 20 is then turned so as to press the roller 17 against the bottom wall of the groove 7 with sufficient force to support the sash in elevated position by reason of the friction between the periphery of the roller 17 and the bottom wall of the groove 7. In other words, this friction is slightly more than is required to counterbalance the weight of the sash.

In raising the sash, the roller 17 rolls freely on the bottom wall of the guide groove. When the sash is released and tends to drop, the roller 17 is instantly checked by the little roller 23 against rotation in the reverse direction, and the friction between the periphery of the roller 17 and the bottom wall of the groove 7 suffices to hold the sash raised. This friction may, however, be overcome and the sash lowered by the application of a slight downward pull on the sash.

From the foregoing it will be evident to those familiar with this art that we have produced a sash holding or supporting device that fulfils the several purposes or objects hereinabove stated in an efficient manner. 7

Without, therefore, limiting ourselves to the precise details of construction, which may be varied to a considerable extent without involving any departure from the principle of the invention, -we claim:

1. A sash support comprising a casing adapted to be secured upon the top of a sash rail, having upstanding side walls at one end thereof, a carrier, including a curved rear wall and parallel side walls pivotally suspended between said casing side walls, a roller journaled in said carrier so as to project beyond the end of said casing, a locking. roller disposed between said first mentioned roller and the rear wall of said carrier in position to wedge between said roller and said wall so as to lock the roller against rotation in one direction, and a spring for yieldingly swinging said carrier outwardly on its pivot.

2. A sash support, comprising an elongated fiat bottom casing adapted to be mounted upon the top of a sash rail and provided at oneend with upwardly extending side portions, a roller carrier consisting of a back and side walls pivotally suspended between said upwardly extending portions, a roller journaled in fixed bearings in said carrier, a spring arranged in said casing to urge the lower end of said carrier outwardlv, and a gravity-actuated locking device loosely positioned in the angle between said roller and said back wall of the carrier for locking said roller against rotation in one direction,

the axis of said roller being disposed out-' wardly of a vertical line through said carrier pivot and beneath said pivot so that a toggle thrust effect is produced against the window frame groove when said roller is locked.

3. A sash support, comprising a casing consistlng of a body member open at one end and having vertically extended side walls at said open end and a cover member having depending flanged s de walls adapted to be secured to a sash rail, a bodilymovableroller mounted in the open end of said body mem-' ber between said vertically extended side walls, a spring in said casing tending to N force said roller outwardly of said open end,

an adjusting screw in the other end of's'aid body member for tensioning said spring, and means limit ng the rotation of said roller to one direction.

4. A sash support, comprising a casing consisting of a bodv member open at one end and having vertically. extended side walls at said open endand a cover member having depending flanged side walls adapted. to be secured to a sash rail, a roller-carrier pivotally suspended from and between said vertically extended side walls, a roller journaled insaid roller carrier, a spring in said casing abutting at one end against said roller-carrier, an adjusting screw in the other end of said casing abutting against the other end of said spring, and means limiting the rotation of said roller to one direction.
