DEWAR, 0F KANSAS CITY, lISSOURI; SAID D-EWAR ASSIGNOE, OF ONE-HALF '.IO ALBA C. HONEYCUTT, OF KANSAS C'J'IY, MISSOURI SASIEC CORD SUPPORT Application led May 12,

Our invention relates to a new article of manufacture in the way of a window sash cord support and one object is to provide novel articles of this character which can be manufactured and installed in window frames at less expense than the metal sheaves and housings usually employed for supporting sash cords.

A further object is to provide articles of this character which will prove more satisfactory in use than the metal sheaves and present friction surfaces to and thereby retard the movements of the sash cords running thereover to such extent that lighter counterweights may be employed for balancing the sash, thereby effecting a further saving in expense.

ln order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. l shows a broken front elevation of a window frame equipped with our sash cord supports.

Fig. 2 is an enlarged broken elevation of the window frame equipped with the sash cord supports.

Fig. 3 is a vertical section on line 3 3 of Fig. 2, with the sash cord removed.

Fig. 4 is a detail perspective vlew of one of the cord supports. j

Fig. 5 is a detail perspective view of a modified form of the device.

Referring in detail to the dilferent parts, A designates a window frame having upper and lower sliding sash B and C and vertical pockets D. The window sash B and C are counter-balanced in the usual way with weights E suspended from one end of each cord F, a pair of which latter are secured to each sliding sash in the usual manner.

2 designates one of the sash cord supports constituting the important feature of the present invention and through the upper portion thereof. Said support 2 consists preferably of a piece of wood having a longitudinal groove 4 extending from end to end. The bottom 6 of the groove 4 is of convex forni to provide a curved surface over which the associatesash cord F can readily bend as it 1928. Serial' No. 277,273.

travels up and down with the associate window sash. Y

While the cord supports 2 may be made from any suitable material we prefer to construct them from hardwood having a close grain so thatthe bottom 'of each groove 4 will present a smooth surface which will not injure the sash cords F as they rrun through said grooves. v

rThe supports 2 are preferably made cylindrical so that they may be readily forced or driven into round holes 8 bored in opposite sides of the window frame A, said holes being of such size that the supports 2 will fit so snugly that they will not become dislodged by the operation of the cords F in the grooves 4. The supports 2 are installed with the grooves 4 uppermost and in order to overcome any possibility of said supports rotating axially and carrying the grooves 4 to one side or the other we provide the lower portion of said supports with triangular shaped countersunk metallic wedge members 10 which become embedded in the frame A, as shown by Fig. 3, as the supports 2 are forced into the holes 8. As shown by Figs. l and 3 the supports project into the window frame pockets D a sufficient distance to prevent the counterweights E, as they move up and down, from rubbing against the sides of said pockets.

While the bottoms 6 of the grooves 4 are made smooth to prevent injury to the sash cords running thereover, said bottoms being stationary, instead of rotary like the sheaves usually employed, will present friction surfaces to said sash cords and thereby retard the movements thereof to such an extent that lighter counterbalance weights may be einployed and thereby effect a further saving.

While we prefer the cylindrical form of support 2 with the curved groove bottom 6, other forms may be employed. In Fig. 5 we have shown a rectangular support 2a having a groove 4a with a three sided bottom 6a, the intermediate side being raised to avoid bending the sash cord at a sharp angle as it runs over said bottom 6a. The latter form of supports will be slightly more expensive to manufacture and install as square holes should be provided for their reception in the Window frame.

The exterior of both supports 2 and 2a are f substantially uniform size throughout their lengths and free from flanges or projections of any character, While ythe grooves 4 and La lare of suicient depth to -receive the respective sash cords Without necessitating the cutting of grooves in the Window frames or the reception of the upper portions of said cords.

From the foregoing description it is apparent that We have provided sash cord supports embodying the advantages above pointed out, and While We have shown and described two forms lof said supports We reserve all rights to such other forms as properly fall Within the spirit and scope of Athe -invention as claimed.

Having thus described our invention7 what We claim and desirefto-secure by Letters Patent, is:

The combination with a Window frame having vertical pockets communicating with cylindrical openings, sash slidable in -said frame, counterweights,operable rin said pockets, and cords connecting said sash and said counterweights, of one-piece -Wooden cylindrical elements driven into said cylindrical openings and each having a groove extending from end to end and through the upper portion thereof and provided -With a convex bottom portion over which the respective cord is adapted to operate, and triangular-shaped 5 Wedge members which are countersunk in the cylindrical elements and driven into the frame.

In testimony whereof We affix oursignatures. JOSEPH KREIMER DUNCAN Gr. DEWAR.
