SPRING-ROLLER.
SPECIFICATION forming part oi Letters Patent No. 350,656, dated October 12, 1886.
A pplicatit n filed May 6, 1886. Serial No. 201.305. (No model.)
To all whom it may concern.-
.Be it known that I, CHAnLEs E. BRooKs, oi the city oi'Brooklyn, in the county of Kings and State of New York," have invented a new and useful In'iprovement in \Vindow- Shade Spring-Rollers,of which the .t'ollowing is a full, clear, and exact description. 7
Reference is to be had-to the accompanying drawings, forming a part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.
Figure 1 isa sectional side elevation ot'a part of a window-shade spring-roller to which my improvement has been applied. Fig. 2 is an end elevation of the roller. Fig. 3 is an end elevation of the same, the cap being removed. Fig. 4 is a sectional end elevation ot'the same, taken through the line as :r, Fig. 1.
The object of this invention is to provide window-shade spring-rollers constructed in such a manner that their revolution will be stopped automatically when the shade has been rolled up to a fixed limit,to preventdisarrange ment or breakage of the roller or its fixturesshould the roller be accidentally released.
The invention consists in the construction and combination of various parts of the \Vlll (low-shade spring-roller, as will be hereinafter fully described.
A represents a windowshade springroller, the spring of which is not shown in the drawings, there is nothing new in its construction or operation.
B is the shade, which is attached to the roller A in the ordinary manner. In the roller A, preferably at or near one end. is formed a slot, into which maybe inserted acase, O, thcedges of which are curved to correspond with the surface of the roller A, and its sides are ilat to fit into the slotin the said roller) The case 0 is made alittle longer than the slot in which it is placed, so that its inner end may enter the body of the roller at the inner end of the said slot, to keep the said inner end of the case in place. Upon the outer end of the case 0 may be formed flanges D, to fit against the end of the roller A, and which are pert'o rated to receive nails or screws to fasten the outer end of the said casein place. The outer end of the case 0 is further secured in place, and the slotted end of the roller A is held l'rom spreading by a cap, E, fitted upon the end of the said roller, and which may be secured in place bynails or screws passing through it and into the end or sides ot'the said roller.
The cap Eis perforated centrally to receive the rod F, the inner end of which enters a perforation in the body of the roller A at the end ot'its slot. The rod F is provided with a collar, G, at the outer side of the cap E, and its outer end is flattened to fit into a slot in a bracket, H, attached to the window-casing to support the end of the roller A and hold the rod F from turning with the said roller. The rod F is provided with a screw-thread extending from the collar G nearly to the other end of the said rod, as shown in Fig. 1.
Upon the screw-rod F is placed a nut, I, which is made of such a shape and size that it can readily move longitudinally in the case 0, but cannot turn in the said case. The case 0 strengthens the slotted roller A against the pressure 01' the nut I as the said nut is turned by the revolution of the said roller.
I11 adjusting the improved shzule-roller for use the screwrod F is passed through the perforation in the cap E, and the nut I is placed upon the saidscrew-rodand screwed npagainst the inner side of the said cap. The case 0 is then inserted in the slot-fin the roller A, and the screw-rod F and the nut I are inserted in the said case, and the cap E is secured to the end ofthe roller A. The shade Bis then wound upon the roller A'to thepoint whichis desired to be the limit of the upward movement of the said shade, and the roller is secured in its brackets. Vith this construction, when the shade B is drawn downward, the revolution of the rollcrA turns the nut I upon the screw-rod F, and causes the said nut to travel toward the in nor end of the said screw-rod until, it the shade is drawn down far enough, the said nut strikes against the solid body of the roller A and the limit of the downward movement of the shade is reached. Vhcn the shade B is again wound upon the roller A, the nut I travels outward upon the screw-rod F until the said nut comes in contact with the cap E and the limit ot'npward movementot' the shadeis reached. Vith this construction, should the shade be accidentiallyn'eleased and allowed to run up, the roller A. will he stopped when the limit of upward movement is reached, and the end of the said shade cannot pass over the roller, taking the coil out of the spring, and causing the breakage of some part of the fixtures.
I am aware that it is not new to employ a contrivance for adjusting thetension of a spring in a window-shade roller, the same consisting of a slotted nut working on a screw, to which latter is also applied the spring,said nut receiv- 10 ing in its slota guide-rod fixed to said roller.
Having thus fully described my invention, I claim as new and desire to secure byLetters Patent CHARLES E. BROOKS.
