ROLLER SHADE Filed July 25, 1932 4 Sheets-Sheet 4 Inventar .eivizaizmii'v By @guna v llomcy Patented' July 11, 1933 UNITED STATES EBMAN H. ROLLER, F AMSTERDAM, NEW YORK ROLLER SHADE Application led July 25,

This invention relates to roller shades, and has more particular reference to the type of roller shade embodying a plurality of slats and capable of being wound and unwound relative to a suitable roller provided therefor, such a shade being, as is well known used either for windows or porches.

My invention relates to an improved type of roller shade together with improved means for mounting the same and for actuating the roller thereof, and the invention will be best understood from a study of the following description, taken in connection with the auccompanying drawings wherein: Figure 1 is a front elevational view of the shade, the same being shown applied to a window and in a fully lowered or unwound condition.

Figure 2 is a longitudinal sectional view thereof the lower portion of the shade being shown in an angular position for Ventilating purposes. y

Figure 3 is a fragmentary vertical sectional elevational view taken through a window having my shade applied thereto and showing the spring actuated drum for winding and unwinding the shade forming part of the invention. V

Figure 4 is a fragmentary horizontal sectional view looking downwardly on the structure shown in Figure 8. Figure 5 is a vertical sectional view through a portion of a modified form of shade.

Figure 6 is a fragmentary perspective view showing the manner of securing one end of a slat to a tape.

Figure 7 is a perspective view of a tape section to be hereinafter more fully referred to. Figures 8, 9 and 10 are fragmentary longitudinal sectional views through additional forms of the shade.

Figure 11 is a side elevation of. one form Y Y of mounting for the spring drum, and Figure 12 is an elevational view illustrating the manner of internally mounting the windino drum.

eferring more in detail to the drawings it will be seen that 10 designates generally a window casing having side members 11 and 1932. Serial No. 624,611.

top member 12. Suitably mounted at the outer side of the window 13 are opposed parallel channel members 14 connected at their upper ends by spaced parallel horizon- `tal strips 15 v'and at their lower ends by a channel member 16. The channel members 14 and connecting strips 15 are braced relative to one another by corner plates 17, while the

channel members

14 and 16 are braced relative to one another by similar corner plates 18.

The channel members 14 adjacent their upper ends are seperated transversely to provide relatively rigid fixed upper sections 14a and swingable lower sections 14?) connected to the sections 14a by suitable hinges 19.

Constrained to slide between the guides 14 is a flexible shade designated generally by the reference character 20. As is common to all forms of the invention the shade 2O comprises a plurality of slats flexibly connected by two spaced flexible tapes 21. The shade 20 is windable on a roller 22 rotatably mounted in the upper window frame member 12, the up.- per ends of the tapes 21 being secured to the roller 22 as clearly suggested'in Figure 2. y The roller 22 on one end thereof is provided with a spool 23 on which is windable a tape or other flexible element 24. Tape 24 is also windable on a drum 25 that is provided with internal spring mechanism 25 and ratchet means (not shown) whereby the drum 25 is caused to normally rotate in one direction and is readily released for rotation in a reverse direction, the type of drum being of a well known form.-

In the present instance the drum is rotatably mounted on astub shaft 26 carried by a bracket 27 adapted'to be arranged in a pocket 28 provided therefor in one side 11 of a window frame adjacent the lower end of said side. Carried by one end of the bracket 27 is a face plate 29 for closing the open side of the pocket 28 as shown in Figures 3, 4 and 12, and this plate 29 is bolted to the window frame or otherwise secured thereto as at 30. The tape 24 is passed through a sleeve 31 lining an ening provided therefor in the frame mem er 12 as shown in Figure 2 and also through an inclined sleeve. Obviously 100 from the description of the invention thus far it will be apparent that by pulling on the tape 24 drum 25 may be released for rotating in one direction, and through the tape 24 transmit the movement of the roller 22 for winding the shade 20 thereon, or for rotating in an opposite direction to transmit, through the.

tape 24 movement to the roller 22 for unwinding the shade 2O as may be found desirable.

When desired the lower portion of the shade 20 engaged with the channel sections 146 may be swung out to the position shown in Figurey 2 for ventilating purposes, and to this end, and for holding the lower sections 146 of the channel members in the position shown in Figure 2 foldable braces 33 are provided, the braces "as is obvious, being pivotally connected at one end with the channel sections 146 and at their other ends pivotally connected to the blind stops as indicated generally at 34.

In each form of shade the slats thereof are provided with notches 35 for receiving the tapes '21, and fastening elements such as shown at 36 in Figure 6 and 36a`in Figure 10 are used to connect the tapes with the slats. Further, in the form of the invention shown in Figure 1 the slats are arranged as to have their longitudinal beveled edges contact one With the other as clearly shown in Figure 2. In the form of the invention shown in Figure 5 the slats are slightly spaced for Ventilating purposes. In the form of the invention shown in Figure 8 the beveled edges of the slats are also formed to provide grooves 37 and tongues 38 for engaging the grooves.

In the form of the invention shown in Figure 9 instead of the longitudinal edges of the slats being beveled, said edges are formed to provide tongues 39 and grooves 40 for receiving the tongues as shown.

In the form of the invention shown in Figure 10 the slats are similar to the form of slats shown in Figure 8, however in this form of the invention instead of having the tapes 21 continuous, said tape consists of a plurality of sections 41, each section 41 shown in Figure 7 being provided at its ends with elongated slots 42, and as shown in Figure 10 the slots 42 accommodate the securing orfastening screws 36a in a manner to provide a pin and slot connection between the ends of the tape section 41 andthe slats.

I have also shown in Figure l1 a modiied form of mounting for the drum 25, the form of mounting shown in said figure being especially adapted for mounting the drum upon the window frame in a manner clearly visible, and without necessitating the providing of the pocket 28 as in the mounting of the drum as shown in Figures 3 and 4. 'Ihe mounting shown in Figure 11 may be termed an outside mounting and comprises a base plate 43 to which is secured the ends of a bracket 44, which bracket 44 and plate 43 supports therebetween a stub shaft 45 on which the'drum 25 is journalled. The upper end of the bracket 44 also has formed integral therewith a. guide mouth or spout 46 through which the tape passes as shown.

Even though I have herein shown and described the preferred embodiment of the invention, it is to be understood that the same is susceptible of further changes, modifications and improvements coming within the swipe of the appended claims.

aving thus described my invention, what I claim as new is:

1. In a roller shade, the combination of a shade, a roller on which the shade is windable, and operating means-for the roller coinprising a face plate having a tubular tape guide projecting therefrom, drum supporting means on one face of the plate, a spring drum mounted in said supporting means, a spool on the roller, and a tape passing through said guide and having its end portions windable on said drum and spool and respectively connected thereto.

2. In combination, a face plate, a bracket mounted thereon, a spring drum supported by the bracket, a tubular tape guide mounted in operative position to said drum, and a tape windable on the drum and passing through said guide.

3. A roller mount comprising a face plate, a drum supporting bracket extending from the back side of the plate at right angles thereto, and a tubular tape guide project-ing from the front side of the plate.

4. A drum mount comprising a face plate provided with means thereon to support a drum, and a tubular tape guide mounted on one side of the plate.

5. A roller mount comprising a face plate, a drum supporting bracket on the front face of the plate and a tubular tape guide mounted on the bracket. i

6. In a drum mount, a drum supporting bracket, a tubular tape guide, and a face plate supporting said bracket and said guide.

7. As -a new article of manufacture, a uni-- tary structure Vconsisting of a face plate having a tubular tape guide projecting outwardly therefrom.

In testimony whereof I aflix my signature.
