WINDOW SHADE cremains DEVICE C Application filed April 26,

The object of this,' my present invention, is the provision of simple means whereby a spring wound window shade may be easily and conveniently raised or lowered without 15 necessitating the operator engaging the shade with the liability of soiling, creasing or tearing the same.

A further object is the provision of an operating means for window shades that includes a slotted pintle fixed in one end of the shade roller and suitably supported on the window casing and to which there is attached and wound therearound a tape or the like, the pintle being of a materially less cross sectional diameter than that of the roller, a revolution of the pintle will cause the roller to also make a complete revolution so that the tape or pull element travels a smaller distance than that of the shade, and whereby the necessity of the operator bending or stooping over to reach the shade in the raising or lowering thereof will be dispensed with and further whereby the tape or pull element, when held during the 5 operation thereof will cause the dogs in the second end of the roller to engage with, the pintle, in the usual manner and thereby hold the shade when fully or partly raised or lowered.

A further object is the provision of a bearing support for the fixed pintle of a spring wound shade roller on which is secured and wound one end of a tape which depends from Hui the pintle along one side of the window trim and terminates in a pull element, the

tape being wound around the pintle in the same direction as the shade is wound around the roller and whereby a short pull upon the tape will cause the unwinding of the shade from the roller, the said shade being held in its raised or lowered positions by the usual cam dogs for the second pintle to which is fixed the spring in they roller.

To the attainment of the foregoing the in- 1950. Serial K013447310.

8 the pintle 5 is I also tape is for distinction indicated by the numeral 12. The cylindrical vcasing 8 has a transverse I opening 13 in its lower wall for the passage of the tape 11, so that the said tape is directed downwardly along one of the vertical trims of the window casing 1. The lower end of the tape has fixed thereto a pull element 14 which is preferably in the nature of a finger engaging lip. The above construction refers to Figures 1 to 4 of the drawings. In Figure 5 the guardfor the pulley 12 and-the journal for the slotted pintle? comprises an outer fixed angle member and an inner'disc16. The

disc is held from longitudinal movement on the slotted-pintle 17 and the tape 18 is, of course, received through the slotof the and is wound therearound and guided between the flange of the member 15 andthe disc 16. r

In Figure 6 the bracket 19 in which the slotted pintle is journaled is of the ordinary construction and disposed opposite the face of the bracket there is arranged and fixed on the slotted pintle '20 spaced discs 21'. The

end of the slotted pintle is journaled in i the bracket and the portion of the tape :secured to and wound around the pintle is guided between the discs 21.

In lieu of the tape any other desired flexible pull element mayv be employed. n

With my improvement it will-be noted that the slotted pintle being of a materially less-cross sectional diameter'than that of the wound around said pintle, said means com prising a bracket to be fixed to a window casing and having an angle flange which is round in plan and through the center of which the pintle is journaled, a second disc on the pintle and the wound portion of the tape being received between the discs so that the said discs provide a guide for the said wound portion of the tape.

In testimony whereof I aflix my signature.

roller a comparatively slight pull upon the eriator or so that-the same can be actuated without necessitating the operator placing his hands upon the shade, which might -re sult in the soiling, creasing or tearing thereof. Even when the shade is fully wound around the roller the same can be readily V lowered whi'ch,4of-"course, overcomes the inconvenience of the-operator standing upon anelevated support to reach the shade.

It is believed the simplicity of the construction and the advantages thereof will understood and appreciated so that fur ther detailed description will not be required.

Having described the invention, I claim:
