SHADE-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 297,030, dated April l5, 1884.

Application nica July 3,1883. (No model.)

To @ZZ whom it may concern,.-

Be itknown that I, HENRY E. STOVER, of St. Louis, Gratiot county, Michigan, and a citizen of the United States, have invented certain Improvements in Shade-FiXtures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication.

MyA invention relates to a window-shade; and it consists in a shade-roller in combination with the devices hereinafter particularly described.

Figure 1 is a front elevation, and Fig. 2 is an end view, of a window-shade and its tixtures containing my invention.

S is the window-shade. i

Ais the shade-roller, intended to beinounted at the top of the window-frame- Upon one end of the rollerpreferably the left-hand end-is the pivot or journal a, adapted to rest in the open bracket-bearing B, which may be formed of a single piece of wire, bent into a curved loop, b, to constitute the open bearing, and with its ends extended at anangle up and down i'rom saidbearing, as at b', the extremities of these ends being bent into loops to receive the fastening screws or nails, as seen at b2. The opposite end of the roller A is extended somewhat beyond the line ot' the edge ot' the shade, and withareduced diameter, to form a barrel. C, upon which the operating-cord is wound. Upon the outerend of the barrel C is fixed the grooved pulley D, as shown, said pulley being preferably of greater diameter than said Extending from the thus formed roller end is the pivot or journal a', which is adapted to rest in the bearingbracket B. This bracket carries the closed bearing b3, which is preferably formed by coiling once upon itself', as shown, a single piece ot' wire, the ends of the wire being extended upward and downward from the said bearing b3, as seen at b4, and their extremities being curved and turned at right angles to said ends, to constitute loops for the fastening-screws, as seen at b5.

E is a friction-lever, which is adjusted to rest in the groove of andthus engage the pulley D, and it passes downward at the rear of' and then around under the said pulley, and its end is then curved or turned sornewhat away from said pulley to constitute the operating-arm c. This lever is pressed against the pulley D by the spring e', and it is preferable that the wire of the lower arm ot' the bracket B should be continued beyond its loop b5, and carried upward beyond the line of the top ot' the pulley D, as at b, then coiled upon itself to form the spring e', and then carried downward, and curved to form the lever Eand its arm c. By this means the spring-lever is readily constructed and mounted in place.

In operating my invention, when the shade is pulled downward, the cord C', attached firmly at one end to the barrel C, is coiled up on said barrel, the friction of the springlever E against the pulley D being overcome by the pull upon the shade, and said lever serving to hold the shade in any desired position when the shade is released from such pull.,A The free end of the cord C passes from the barrel C through a bearing-loop, e2,

Aformed on the end ot' the arm e ot the lever E, and depends thence at the side of the window-frame. When it is desired to roll up the shade. the cord C is pulled downward, and it operates, by its engagement with the loop e2, to draw thelcver E out of engagement with'the pulley D, and thus leave the roller A free to rotate, and the pull being con# tinued, the uncoiling ot' the cord from the drum C rotates the roller and rolls up the shade thereon. Vhen the cord C is released, the lever E is carried by its spring into engagement with the pulley D, and the roller is consequently held stationary, and the shade thus retained atthedesired height.

What I c laim as my invention, and desire to secure by Letters Patent, isi The combination, with the shaderoller A, journaled at d ct to run freely in bearings, as described, and provided with the barrel C and operating-cord C', together with the pulley D, of the bracket B, carrying the bearing b3, and the friction-lever E, with its spring e', arm e, and loop e2, said bracket and lever being formed of a single piece of wire bent and turned upon itself to constitute said bearing, lever, spring, arm, and loop, as specified, and for the purpose set forth.
