ATENT OFFICE;
WALTER B. NOYES, OF BOSTON, MASSACHUSETTS.
CURTAIN- ROLLER.
SPECIFICATION forming part of Letters Patent No. 225,857, dated March 23, 1880.
Application filed Juno 24, 1875).
To all 'whom tt may concern:
Be it known that I, WALTER B. NoYEs, of Boston, in the coun ty of Suifolk, and inthe State of Massachusetts, have invented certain new and useful Improvements in Curtain-Rollers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the aceompanyingdrawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention consists in the construction and arrangement of a spring curtain-roller, as will be hereinafter more fully set forth.
In order to enable others skilled in the art l to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a longitudinal section of my invention. Figs. 2, 3, and 4 are detailed views of parts thereof.
A represents the wooden spindle, one end of which is bored to receive the iron spindle B. This spindle B has two side wings, Z1 b, to enter corresponding slots in the bearing a of the bracket O. (Shown in, Fig. 3.) The other end of the wooden spindle zA iscut away for a suitable distance to receive .the spiral spring I). A metal ferrule, d. is fastened on each end of the wooden spindle A. The spiral spriu g D is put on the reduced portion of the wooden spindle after it has been eut off the proper length, to give the required tension to hold the roller in the brackets. The large or torsion spring E is then slipped ou the spindle A, the small end next to the head or metallic spindle. I is a metallic tube fitted and attached to a wooden plug, G, and a Washer, c, is placed in said tube against the end of the plug. The reduced end of the spindle A is then passed through the tube F and Washer c, and through the plug G, the end projecting' into a recess formed in the outer end of said plug. The washer c prevents the spring D from coming in contact with the wood. A pin, j', is then passed through the projecting end of the wooden spindle, when the whole is fastened together ready to go into the roller.
In the recess in the end of the plug G is a screw or other stop, It, against which the pin f will come. It will readily be seen that by pressing the plug G inward the pin f will clear the stop h, and the torsion-spring E can then be wound up more or less, as required, and the spiral spring D will, as soon as the pressure is removed from the plug, bring the parts back to their former position, and the pin f against the stop h prevents any further unwinding of the spring, though in practice it will be wound still more when the curtain is pulled down. This device is then inserted into the hollow roller H, and the head end I put on and glued. At the same time the foot -plug G is nailed solid to the roller. To one end of the roller is then attached a head-piece, J having arecess in its outer side, in which recess one or more dogs, m m, are pivoted. These dogs may be pivoted directly to the head, or to a plate fastened in said head, and they are intended to take into the slots in the bearing a of the bracket to formA a stop-curtain. These dogs operate by gravity as they pass over the top of the bearing a. If the movement of the roller be slow, the dogs will drop into the slot and stop the roller. If the movement be rapid, they will pass over the slot without dropping in.
When only one dog is used the roller can only be stopped once during each revolution, and by increasing the number of dogs the number of possible stoppages for each revolution is correspondingly increased.
When a balance and not a stop-curtain is desired, the dogs m may be held out of the way by pins t'.
One cud of the torsion-spring E is fastened to the tube F or to the plug G, and the other end to the wooden spindle. As the curtain is lowered the spring E winds onto the spindle, and the spindle is forced against the tube with a greater or less force, according to the winding of the spring creating a friction in proportion to the weight of the curtain, thus evenly balancing a light or a heavy curtain. The tube will yield easily, and operates, therefore, as a spring to a certain extent. The tube F also prevents any interference of the torsionspring with the spiral spring.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The combination, with e hollow curtainroller, of the spindle A, cut away, es shown, at one end, the hollouT plug G, having the end of the spindle free to move endwisc therein, but locked from rotating movement by the pin f und stop h, es described, the springs D E, and the tube F, interposed between the springs, so that one will be entirely inelosed thereby :incl the other pass over the outside of the tube, substantially :ts and for the purposes herein set forth.
- In testimony that I claim the foregoingI 15 have hereunto set my hand this 21st.dey of May, 1879.
