Aug. 6, 1935. K. BRAUN COMPENSATING DEVICE FOR SASH WINDOWS AND THE LIKE Filed July 2, 1934 Patented Aug. 6, 1935 i 2,010,214 v UNITED STATES-PATENT"OFFICE COMPENSATING DEVICE FOR SASH WINDOWS AND THE LIKE Karl Braun, Augsburg, Germany Application'July 2, 1934, Serial No. 733,371 In Germany July 3, 1933 Claims. (01. 16-198) My invention relates to sash windows having and their orderly dropping into the grooves is devices for compensating the weigh t of the sash, ensured. If the shaft were disposed horizontally the cords of which, when the sash,.is raised, will the wound portions of the cord would, because be wound upon one or more spring controlled of the angle of inclination of the grooves, press 5 rollers or drums. against their flanks. In order to prevent exces- 5 According to this invention the/object of which sive friction from this cause the shaft is therefore is to ensure the sash cords being 'wound properly, according to the invention, inclined to the horithe rollers or drums are mounted rotatably upon a zontal to such an extent with regard to the pitch stationary shaft in such a manner, that during of the grooves that the cords will chafe against each revolution the rollers will travel sideways the flanks of the grooves, but will drop into the 10 a distance equal to the thickness of the cord. bottoms thereof.
Agreeably to this purpose the end of the shaft upon It is of course, within the scope of the invention which the roller rides and the bore-of the roller to provide separate compensating devices for are provided with threads engaging one with the each of the. cords 5 and 6; the grooves on the other. The rollers rotating when the sash is drum would in that case be single-threaded. But 15 raised will consequently at every rotation also a great deal of material, and also of space, is move a certain distance sideways along the shaft. saved by the embodiment just now described The drawing shows, by way of example, a pre- I since, as shown in the drawing, on the right hand ferred form of the sash window embodying the side of the window a second compe ev e invention. for a second window sash could conveniently be 20 In the drawing, I indicates the stationary shaft placed. of the compensating device which is supported What I claim is: in blocks 2 and'a attached to the window frame, 1. A comp n i vi f r sash windows and 4 indicates a drum like roller the surface of which the like, comprising a stationary shaft having a is provided with a pair of identical grooves for the threaded portion, a grooved drum rotatably 25 accommodation of the sash cords 5 and 6 from mounted on said shaft and havin a threaded which the sash is suspended. The drum 4 is of bore engaging the threads on said shaft so as to conical shape and the grooves form a double move uniformly lengthwise thereonwhile being thread thereon. The two grooves being identical rotated, and tensioning means for rotating said both sash cords 5 and 6 may be wound side by drum. 30 side on one and the same drum. For the purpose 2.
