H-..H. PHILLIPS.. y ImPIOVement in Curtain Fixtures. N0,124,153 Patented Feb. 27, 1872.
NTTED STATES HENRY H. PHILLIPS, OF BUFFALO, NEW YORK.
IMPROVEMENT INCURTAlN-FIXTURES.
Specification forming part of Letters Patent No. 124,153, dated February 27, 1872. l
To all 'whom t may concern:
Beit known that I, HENRY H. PHILLIPS, 0f Buifalo, in the county of Erie and State of New York, have invented a new and valuable Improvement in Curtain-Fixtures 5 and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.
Figurel of the drawing is a representation of an end view of the spring-barrel. Fig. 2 is a sectional view of the same. Fig. 3 is afront view.
My invention has relation to curtain-f1 xtures designed for use in the manipulation of heavy curtains of store windows. The curtain to which my invention applies has connected with the roller on which it is wound a coiled spring, which is compressed as the curtain is unrolled and pulled down, and which has a tendency to roll up the curtain when the adj ustng devices are released. My invention consists in uthe combination with said coiled spring, when properlyarranged, of the ordinary curtainx ture, consisting of a grooved Wheel attached to the curtain-roller, an endless cord, and a cord-holder and tightener. The object of my invention is to provide for the perfect control of heavy window-shades, the raising of which is aided by means of a coiled spring. endless cord is used in this relation as a means l of adjustment, so thatthe curtain may be held TheV curtain and controllingthe action ofthe spring in rolling the curtain up..
In the accompanying drawing, A represents the curtain or shade; B, the roller; O a hollow drum or box containing a coiled spring,D, which is secured to the-roller-shaft d, and is tightened as the curtain is unrolled. E represents an endless cord passing over a grooved pulley, F, attached in the usual manner to the roller B. G designates the ordinary cordtightener, having a knob, g, to hold the cord. The cord, when applied, is tightened to a sufficient degreee as to overcome the force of the spring, and prevent the curtain being rolled up when it has been adjusted to any desired point, unless the cord be further manipulated. The spring is just barely governed by the cord; hence a very slight force on the cord is needed. By the loosening of the tension on the cord the roller may be allowed to roll up as swiftly as may be desired.
What I claim as my invention and desire to secure by Letters Patent, is-
The combination of the roller B, pulley F, endless cord E, and cord-tightener Gr with the coiled spring D incased within the hollow drum O, substantially as and for the purpose specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
HENRY H. PHILLIPS.
