TO ALL WHOM IT MAY CONCERN:
Be itlknown that I, STEWART HARTSIIOR'N, of the city, county, and State of New York, have invented a new and useful improvement in Spring-Shade Rollers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to a new and useful improvement in spring-shade rollers, those which have a spiral spring connected or applied to them in such a manner asnto roll up the shade, and thereby dispense with the cord and pulley originally used for that purpose. Hthcrto these rollers have been constructed of metal tubes with the spiral spring fitted within them-an expensive mode of manufacture. The present invention consists in employing an ordinary wooden roller, hung in suitable bearings, and connected by gears to a spiral spring on a short shaft above, all beinror arranged as hereinafter fully shown and described, whereby'the same result is obtained as by the original expensive means. In the accompanying sheet of drawings- Iligure is an cud vieur of my invention.
Figure 2, a front view of the same.
Similar letters of reference indicate like pairts.
A represents a Wooden shade roller, which may be constructed in the same way 1s those now employed for being wound up with a cord and pulley. This roller is ,hung in proper bearings, a, attached to the windowfmme, and on one end of this rollerl there is secured a tothe'd wheel, B, into which a Wheel, C, of larger diameter gears. This wheel C is placed loosely on one end of a shaft, D, which has a spiral spring, E, one end of said spring being attached to -the shaft D, as shown at b, and the other end attached to a hub, F, tc `rhieh the wheel Cis secured, and which, like said wheel, is placed loosely on the shaft D. The spring E is wound up, as the roller A is turned in pulling the shade G down, and hence it will he seenthat if the spring E he strong enough it will Wind up the shade when the same is released. In practice, I design to have the spring E ot' such a strength that it will counterpoise the shade, so that the same'may be wound up by simply pressing upward against the rod, in a hem, c, at its lower end. The shaft D, it will of course be seen, is not allowed to turn. It is a fixture, ard necessarily so, in order that the spring may be wound up when the shade is pulled down. I would remark that in lieu of the gears B C, pulleys anda belt may be used, the pulley on roller A, being secured to it, uhile the one on shaft D is placed loosely on it, and has one end of the spring E attached. This device, however, is equivalent to the gears. This arrangement of the spring and its shaft at the-outer side of the shade roller, and -the roller and spring connected by gears or their equivalent as described, may be manu-v 4factored at a very n'rodcrate cost, and will operate equally as well as the comparatively expensive tubular roller with the Spiral spring placed within it.
Having thus described my invention, I cla-im as new, and desire to secure by Letters Patent- The construction and arrangement of the short ixed shaft E, above the shade roller A, surrounded by the spiral spring D, one end of which is secured thereto atb, the other end attached to the loose hub F, of the gearwhccl C, meshing into the gear-wheel B upon the end of the shade roller, substantially as herein shown and described l'or .fhe purpose specified.
