BLIND OR SHADE.

Specification of Letters Patent.

Patented llllay 2, 1916.

Application filed July 6, 1915. Serial No. 38,222.

To all fw tom t may concern Be it known that we, VALTER C. Doorn- .irfr and Frizzi; Sirrzrrsnnnnn, citizens of the United States, residing at Pittsburgh, in the county of 'lllegheny and State of Pennsylvania, have invented certain new and useful Improvements in Blinds and Shades, of which the following is a speciication.

This invention relates to blinds or shades and has for its object to provide means '1n connection with the blind or shade in a manner as hereinafter set forth to facilitate the raising or lowering of the blind or shade and to further prevent the swinging outward or laterally of the blind or shade roller during the vertical movement of the latter.

A. further ob'ect of thel invention is to provide a porch blind or shade having means in a manner as hereinafter set forth, constituting a guide for the roller of the blind or shade during the vertical movement of the roller and to further provide a porch blind or shade which is simple in its construction and arrangement, strong, durable, efficient in its use, conveniently operated, overcoming lateral or outward shifting during the winding and unwinding thereof, and inexpensive.

lNith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

1n the drawings wherein like reference characters denote corresponding parts throughout the several views z-Figure 1 is a sectional elevation of a porch showing the adaptation therewith of a blind or shade in accor-dance with this invention. Fig. 2 is a side elevation. Figs. 3 and l are sectional details. Fig. 5 is a sectional plan, broken away, of a modified form of blind or shade roller.

1t is to be understood that the term shade is generic, for blind, shade, or awning.

Referring to the drawings in detail 1 denotes a porch and 2, 3, the uprights thereof.

-1 denotes a top bar which is secured between the uprights 2, 3, and has projecting outwardly therefrom staples 5, constituting supports for hangers 6 which are connected to the bar 7, to which the upper end of a shade 8 is attached.

Secured to the uprights 2, 3, are vertically disposed guides 9, having inwardly extending angle-shaped ends 10, in position by the hold fast devices 11 and which offset the guide rods 9 with respect to the uprights 2, 3.

The reference character 12 denotes a roller upon which the shade 8 winds on and off and the roller is carried at the lower end of the shade.

Pulleys 13 are attached to the bar 4. and over which travel elevating and lowering cords 14 which extend under the lower end of the shade 8 and have one end connected to the bar -1 and the other ends are adapted to be detachably secured to the cleat 15. By pulling on the cords 141 the shade is rolled up and by loosening the cords the shade is allowed to lower.

The roller 12 has secured to each end a disk 16. Screws 17 are employed for fixedly securing the dish in position. Each end of the roller has a recess 18 and seated in each recess 18 is the head 19 of a pintle 20, which extends through the disk 16 and has its outer end provided with a head 21, seated against the inner face of a ring The pintle 20 extends through the ring 22 and the latter is mounted upon a guide rod 9. The pintle 2O loosely extend through the dish 16 and rings 22 whereby the roller 12 can turn independently of the shifting movement of the rings 22, during the elevating and lowering of a curtain and by such an arrangement binding of the roller with respect to the guide rods 9 or binding the rings 22 with respect to the guide rods 9 is overcome.,

The rings 22 prevent the lower end of the shade from swinging outward or laterally during the elevating and lowering the shade and also overcoming the necessity of employing a. series of rings or eyes which are usually carried by the shade to prevent shifting thereof outward or laterally.

Although a pair of guide rods are illustrated as associating with the rings 22 it is to be understood that the guides can be made of rope or cord if desired.

Referring to Fig. 5, 23 denotes a ring, 24 a guide rod and 25 the pintle which is formed integral with a flange cap 26, secured to the roller 27 by the hold fast devices 28. The ring 23 has an opening 29 for the passage of the pintle and the latter which are secured is provided With a head 30 whereby the ring 23 is loosely-connected With the roller.

at We claim isn" An attachment for porch shades compris- 5 ing a palr of cylindrical pintles adapted to l tending` through said cylindrical openings be loosely mounted Copies of this patent may be obtained for fivel eents each, by addressing the gilides extending through and associated with said rings to prevent lateral shifting.

the inner diameter of said rings being mate- WALTER c. DoUTinT'T. FRANK STUTTERHEIM. Vit'nesses B. E. JENKINS, LUELLA H.l SIMON.
