TO. ALL WHOM IT MAY CONCERN:
Be it known that I, J'oHN'IO. GOVEltS, of the city of Washington, in the District of Columbia, have invented certain new and useful Improvements in Devicesfor Adjusting Window-Shades and I do hereby declare that the'following'is a full, clear, andexact description thereof, reference beinghad to the accompanying drawings, making partof this specification, and to the letters of reference marked thereon, like letters indicat ing like parts wherever they occur. i i
To enable others skilled in the art to construct and use my invention, I will proceedto describe it.
My invention relates to window-shadeaand consists ina novel construction and arrangement of devicesv for adjusting the shade at difi'erent heights, at will, and also for having it wind and unwind on the roller, at whatever point it maybe adjusted. In the drawin'gs- I Figure 1 is a front elevation on the inside.
Figure .2 is a longitudinal vertical section on the line :v-x of fig. 1.
Figures 3, 4, and 5, are views of partsdetachedQ.
In hanging window-shades, it is often very desirable to have the roller, upon which they turn, andjfrom which they are suspended, arranged so that it may be adjusted at different heighizsrwiizhoutinterfering with the-- devices for raising and lowering the shade itself; and it is also desirable to constructthe devices for this purpose in such a way that they may be readily applied to' all classes of windows. -My invention has for its object these purposes. I v I In constructing and arranging m y devices, I cut longitudinal grooves, B, inthe stops'G, onach side of. the window, as shown on one side in fig. 2. Immediately over the grooves B, and at the extreme upper end of the stops G, I insert pulleys A, as shown in-fig. 1. Between. the grooves B, I place the roller 0, having circnlar openings in each end to receive the journals D, which are constructed with a cross-bead or slide, 2:, attached, as shown in figs. 3, '4, and 5, to slide in the grooves B, as shown in fig. 2. Between the inner end of the journal D and the bottom or end, of the opening, at one end of the roller C, I insert a spiral spring, g, or other suitable device, for pressing the slides e against the inner sides of the grooves B, and thus holding the roller 0 in place. I can also-securc thc same result by making the roller 0 hollow its entire length, and placing the spiral or other spring between the ends of the journals D, having made them long enough for the purpose. To the upper. ends of the heads of the slides a, I attach a cord,a, which passes over the pulleys A, and attach to it a tassel, b, which has within it a weight of lead, to assist in balancing the shade F, when placed on'the'roller C. The attachmentof thefcord a to the head of the slide e, and the manner of passing it over thepulley A, are clearly shown in fig. 3. In the'continuation of the stop G across the upper side of the window, and at one side, I insert-a pulley, E,.as shown'in dotted lines in fig. 2. The end ofthe roller 0, under the pulley E, I provide with agrooved wheel, It, or one may be turned on the roller when it is made, and at' the bottom of the groove B, or: at any suitable place, I attach the common adjustable curtain-fixtare 2', as shown in figs. 1 and 2. I then passthe endless cordfover the pulley E, and pass it once around the grooved whelh, and then down around the fixture a, as shown in fig. 2. The manner of passing itaround the groove or grooved wheelat the end of the roller 0 is clearly shown in fig. 3. The object of making the slides'e long, as shown in figs. 4 and 5, is to give. them a greater bearing in thegrooves B.- To the slides e,'below the journals 'D, I attach the cord H, and provide it with tas'selJ in the centre. 4 v
i When the curtain 'F is hung in this way, by'pulling downward on, the cord H, the roller 0 may be made to descend as far as desired, the cordf moving freely on the fixtures 2' and pulley E, but remaining stationary on the groove or grooved wheel at the end of it. Thebearing of the slide e against theinner sides of the'grooves caused by the spring g, together with the balancing weight in the tassel s b, will cause; the roller C to remain at whatever point it may be drawn. To pull it up, it is only necessary o take hold of the tassels b and pull downward. I
' It is obvious that this arrangement of devices may be applied to' windows when first constructed, or afterwards. In this way I am able to construct and" arrange a cheap and convenient device for adjusting window-shades.
Having thus described my invention, what I claim, 'is- 1. In combination with the roller 0, the springg and journals D, with the slide 6 attached to move in the grooves G, when constructed and arranged to operate substantially as described.
2. The-roller C,-spring g,journals D, and slide e, attached, in combination with the groove G, and cords a anc'Lf, when constructed-and arranged to operate substantially as described and for the purpose set forth.
