OSCAR D. WOODBURY, OF NEW YORK, N. Y.
STOP Fony sPRlN'e-ROLLERS.
September 25, 1883.
Application flied April 7,1883. (No model.)
` To allwhom t may concern:
Y Be it known that I, OscAR D. VOODBURY, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Stops for Spring-Rollers, of which the following is a specification.
My invention may be employed in connection with springrollers for heavy curtains or blinds, or with spring-roller devices for suspending bird-cages, lamps, or other articles.
The principal object of my invention is to provide mechanism whereby the rollerv will be stopped periodically once in each revolution or less when turning by the action of the spring,
and whereby the roller may be released and allowed to continue its revolution until again stopped; also, to provide means which will form a positive' stop or lock to the roller to prevent its rotating against the action of the spring when any device is suspended from it,
whereby the article, even if it be of consider` able weight, is held fast and'prevented from falling.
The invention consists, essentially, in the combination of a spring-roller, a cam of novel form carried by-said roller, a spring-actuated stop or dog, which engages with the cam and forms a stop for the roller, as more fully hereinafter described, and as pointed out in the claims, and a novel means for releasing` the roller from the aforesaid stopy or dog.
The invention also consists in combinations.
of parts hereinafter described and claimed.V
In the accompanying drawings, Figure l represents a side view ofa spring-roller and suspension device embodying my invention. Fig. 2 is a front view thereof,- and Fig. 3 is a sectional elevation on the dotted line x x, Fig. 1.
Similar letters of reference designate corresponding parts in the several figures.
A designates a hanger or frame, which may be of metal, and which may be suspended from or secured to any suitable support.
B designates the roller, which is j ournaled on an axle or pin, a; end or side a cylindric cavity, B', wherein is arranged a coiled spring C, `the inner end of which is made fast to the axle or pin a, while the outer end is secured to the roller. The spring C tends constantly to turn the roller B in the direction of the arrows7 Figs. 2 and 3.
two plates to the'back `of the roller.
The roller has in one VThe roller B is grooved circumferentially at b,
and has wound around it a cord, D, or, in lieu thereof, a chain or analogous device, which may be provided at the end witha suspensionhook, c.
E designates a lever or arm, pivoted at d to the hanger or frame A, and carrying a pin, e, which bears against the periphery or face of the roller B, as shown in Fig. 1. This lever or arm has projecting from it a pin or stud, f, over which the cord D passes, and the lever is impelled upward by a spring, g,so as to hold the pin e against the periphery of the roller B. Below the stud` or pin j' the cord D passes `through a guide or eye, h, and it will be seen that by reason of its bearing on the said pin or stud the cord is deflected in passing from j thev guide-eye l1J to the periphery of the roller B, as shown best in Fig. 3, so that any pull upon the cord will' have a tendency to draw down the lever or arm E. In the back or side of the roller B are two cams, B2 B3, which may be formed by cutting a groove or channel, 1', of peculiar shape,in the roller, or by attaching When the roller B is relieved of any weight or pull on the cord D, it is turned by the spring O in the direction of the arrow, Fig. 3, and as the lever or arm E is pressed upward constantly by the spring g, the end t" of the groove or channel t' catches the pine. This offers no impediment to the turning of the roller, however, until the projection orportion i2 of the cam B2 strikes the pin e, as shown in Fig. 3, whereupon the pin e forms Aa stop or'dog to prevent the turning of the roller. In order to release the roller, the cord D must be pulled to draw down the lever E and move the pin' c out of the way of the projection 2, whereupon the roller continues its rotation until it is again checked. Therefore it will be seen that when turned by the force of the spring 'C the roller Will be checked automatically at each revolution and cannot fly up or turn unrestrained, as spring-rollers commonly do. y
In lieu of having the cord D passed over the stud f in order to pull down the lever-arm E,
I may attach a separate cord thereto.
On the cam B3, at a point just behind the projection ft2, is a projection or shoulder, i3, and when the lever E is pulled down to move the pin e out of engagenient With the projection 2 the said pin is carried infront of or into engagement with the shoulder i, as shown dotted in Fig. 3, and forlns a positive stop,which prevents the roller from turning in a contrary direction to that indicated by the arrow. Consequently, if a bird-cage or other article be suspended by the cord D, the roller will be held against turning under the influence of the weight of the suspended article by the stoppin e, and the article on the cord D will be rigidly suspended. If the cord D be released after pulling down the lever or arm E to carry the pin c out of engagement with the projection il, the roller will continue its rotation7 the pin e following the groove t' and leaving the groove at the end fi". The pin e constitutes a dog or stop, and the lever or arni E a carrier there for. Instead of being pivoted, the said carrier maybe made in the forni of a sliding bar, or otherwise constructed.
Vliat I claim as my invention, and desire to secure by Letters Patent, is-,
l. The combination, with a roller, its act-- uating-spring, and ak cord or analogous device Wound on the roller, of a cani carried by the roller, a dog or stop, with which said cani may engage to stop the roller, and a carrier for said dog or stop, over which the said cord or device passes, and which is capable of being nioved by a pull upon the cord or device to Withdraw the dog or stop from the said cani and allow the said roller to turn, substantially as and for the purpose described.
2. The combination, With the roller B and its spring C, of the earns Bl B3, provided with the projections or shoulders 132 i, the dog` or stop e, and a carrier therefor, all arranged and adapted to operate substantially as described.
3. The cenibination,with the roller B, spring C, and cord D, ofthe canis B2 B3, having projections i i, the pivoted carrier E, provided with the stop or dog e, and the stud or pin f, over Which the cord D passes, all substantially as and for the purpose described.
