Paige, Spout Spring, Va. Application January 19, 1937, Serial No. 121,334 2 Claims. This invention relates to what is believed to be a structurally new and novel shade roller in support and operating means therefor, wherein the arrangement is such as to substitute a manu wound on the roller as seen in Figure 1. ally controlled operating mechanism for the so called conventional pawl and ratchet spring ac tuating means. Seeking to improve on known prior patented and The so-called right hand supporting and hanger ?xture is differentiated by the numeral l3. It comprises an apertured attaching ?ange I4 and marketed arrangements, I have perfected aptly ?tted structural details mutually cooperating in a well planned assemblage constituting what is be The central portion of the plate indicated at I6 In reducing to actual practice the principles of ' my ideas, I have found it expedient and practica ble to utilize a pair of similar supporting brackets provided with ball bearing devices to rotatably and effectively support the trunnion equipped ends of the shade roller, whereby to facilitate rais 20 ing and lowering the shade. The principal feature of the invention is, how 30 in Figure 6 is formed into a cup I‘! to accommo date a. notched roller bearing unit 18. The en 10 trance notch [9 permits insertion and removal of the trunnion II. The left hand or opposite supporting. ?xture is denoted by the numeral 20. This also includes an apertured attaching ?ange 2| and an out standing wing or plate 22. As seen to advantage in Figure 4, the central longitudinal edge por tion of the plate is formed. into a circular cup 23, facing outwardly and containing therein a suit able ball race or bearing unit denoted by the nu meral 24. This arrangement provides the desired pull chain having its free workable ends depend ing in parallelism within convenient reach to fa~ cilitate positioning the shade in the desired posi tion and satisfactorily holding it set in such of the roller in ball bearing races, the shade may 25 be wound and unwound easily. Attention is now called to the numeral 25 in Figure 4. This comprises a suitable receptacle, position. guiding and tracking adapter for the pull chain Other features and advantages will become more readily apparent from the following de scription and drawings. In the drawings: v. 7, an outstanding right angularly disposed plate l5. ever, predicated on the adoption and use of es— capement-like pawl and ratchet means wherein the ratchet wheel is directly coordinated with a ' Figure 1 is an elevational view, essentially in v constitute .trunnions or journals I0 and H. The shade, which may be of any appropriate construc tion, is denoted by the numeral l2 and is shown lieved to be a desirable and appreciable contribu tion to the art. IQ Ll (Cl. 155—28) section, showing the complete assemblage as con structed in accordance with my personal ideas. ' Figure 2 is an end view of Figure 1 observing it in a direction from left to right. Figure 3 is a sectional view which may be said 40 to be taken approximately on the plane of the line 3—3 of Figure 1. Figure 4 is a detail elevational view of the left hand bracket and its appurtenances, the chain being removed for clearness of illustration. Figure 5 is a perspective view of the spring pawl and its attaching element. Figure 6 is what may be designated as an out side elevational view of the right hand bracket shown in Figure 1. Figure 7 is a fragmentary perspective view of 50 one end portion of the shade drum or roller. In the drawings the wooden shade roller is de noted by the numeral 8 and this embodies a cen tral axle or shaft 9 whose ends extend beyond in 5 the corresponding ends of the roller proper and anti-friction support or bearing for the trun nion I0. Consequently, by supporting both ends 26. It includes a suitably curved track or hanger ; ?ange 2i having down-turned guides 28 at oppo site ends. These guides lead the chain-ends down into desired parallelism for convenient reach and operation. The numeral 29 designates an attach ing flange, and this is secured to the inner side of the bearing cup 23. ‘This adapter bracket 25 serves to accommodate the marginal tubed por~ tion of the escapement or ratchet wheel 30, this being keyed on the trunnion l0 and interposed between the bearing cup 23 and said adapter ?x tures 25, as well as the adjacent end of the wooden part of the roller 8. Also attached to the bearing cup‘ is an L-shaped member 3| carrying the spring trip or pawl 32. The pawl is located for releasable ratcheting en gagement with the teeth of the ratchet wheel 30. Assuming that the device is set up and as sembled as shown in the drawings, and referring to Figure 2, it is evident that by pulling either end of the chain 26, the links thereof being in mesh or tracking connection with the teeth of the gear wheel, said wheel is rotated and this in turn rotates the shade roller, permitting winding or unwinding of the shade depending on the di rection of movement of the chain. The spring 2 2,114,568 pawl provides the desired ratcheting action and of companion supporting and attaching brackets, also serves to retain the ratchet Wheel set when a shade roller having trunnions at its opposite the shade is located, through the instrumentality ends, said brackets being provided with bearings of the chain, in the desired position. receiving the trunnions to facilitate rotation of It follows, therefore, that the gist of the in the roller in either direction, a toothed Wheel con‘ vention is predicated upon a pair of companion nected with one trunnion, a chain hanger con supporting brackets attachable to the frame and nected with one bracket and having a curved ?ange extending under the lower part of the provided with roller bearing devices to accommo date journals or trunnions on the opposite ends of the shade roller. This is one feature. Sec ondly, novelty is predicated upon the chain actu ated ratchet wheel and pawl and ratchet features cooperable with the chain. More speci?cally, novelty is predicated on the individual ?xtures I3, 20, and the accessories 25 and 3| and 32 seen in Figure 4. Or stated otherwise, novelty is based on the structural coordination of features in com bination as well as the individual component parts which mutually cooperate to render the structure e?icient and reliable. ‘ It is thought that the description taken in con nection with the drawings will enable a clear un derstanding of the invention to be had. There fore, a more lengthy description is thought un necessary. While the preferred embodiment of the inven tion has been shown and described, it is to be un derstood that minor changes coming within the ?eld of invention claimed may be resorted to if desired. I claim: 1. In a structure of the class described, a pair wheel, semi-tubular guides extending downardly and outwardly at the ends of said ?ange and a 10 chain having an intermediate portion passing over the ?ange and through the guides and said portion of the chain engaging the teeth at that part of the Wheel located in the hanger. 2. In a structure of the class described, a pair 15 of supporting brackets, a roller having trunnions at its ends rotatably arranged in said brackets, a toothed wheel on one trunnion, a chain hanger connected with one bracket and having a down wardly curved ?ange for receiving the lower part 20 of the wheel and downwardly and outwardly curved guides at the ends of the ?ange, a chain having an intermediate portion passing over the ?ange and through the guides with its links en gaging the lower teeth of the wheel, a small 25 bracket supported from that bracket carrying the hanger and a spring detent carried by the small bracket and engaging the upper portion of the toothed wheel to frictionally hold the same against movement.
