JAMES D. GRISWOLD, OF BROOKLYN, ASSIGNOB TO THE ANSONIA BRASS AND COPPER COMPANY AND WOLOOTT A. HULL, BOTH OF NEV YORK, N. Y.
SUSPENSION DEVICE FOR LAMPS, 8:.0.
SPECIFICATION forming part of Letters Patent No. 363,063, dated May 17, 1887. Application filed January 28, 1886. Renewed February 18, 1887. Serial No. 228,121. (No modeli) T0 aZZ whom it may concern.-
Be it known that I, JAMES D. GRISWOLD, of Brooklyn in the county of Kings and State of New York, have invented a certain new and useful Improvement in Suspension Devices for Lamps and other Articles, of which the following isa specification.
I will describe in detail asuspension device embodying my improvement, and then point out the novel features in the claim.
In the accompanying drawings, Figure l is a side elevation, partly in section, of a suspension device embodying my improvement. Fig. 2 is a plan or top view ofthe same.
Similar letters of reference designate corresponding parts in all the figures.
A designates a hollow cylindrical drum provided upon its periphery with flanges a. Cords or chains B are wound upon the drum be tween the flanges a, and pass from thence over guides O to the article suspended.
The drum A is mounted upon an arbor, D, which, as here shown, is vertical. The drum may rotate freely about the arbor. One end of the arbor is rigidly secured. by a feather or otherwise, to a frame, E, shown in this ex ample of my improvement as arranged below the drum. A nut, 7), upon the lower screw threaded end of the arbor tends to prevent the frame E from moving off from the arbor D. A loop, F, having a swiveling connection with the arbor, near the upper end of the latter, is employed tosuspend the device from a hook or other support.
Within the drum isacounterbalancespring, G. One end of this spring is secured to the arbor and the other end to the drum near the periphery thereof. This spring is intended to counterbalance the weight of a lamp or other article suspended from the cords or chains B. When the drum is rotated in the direction to unwind the cords or chains, the spring is coiled up more tightly. When rotated in the direction to wind up the cords or chains, the spring is uncoiled.
I-l designates brakes for retarding the rotation of the drum. As shown, these brakes consist of framelike structures provided upon one end with a concave surface, the concavity of which is struck approximately in the arc of the circle described by the flanges a of the drum. These concave surfaces will preferably be faced with rubber, leather, or analogous material. They are adapted to bear against the flanges a of the drum when the weight of the suspended article is exerted upon the cords or chains B. The guides C, over which the cords or chains pass, are here shown as pulleys. They are mounted upon axles c in the side portions of the frames of the brakes H.
The brakes H are supported in guides l, forming portions of arms d upon the frame E, and extending upwardly outside the drum A. These guides are preferably provided upon their inner surfaces with groovesf, extending in the direction ofthe length thereof, into which extend ribs 9 on the brake-frames.
The brakes have a free bodily movement toward and from the drum. They are moved toward the drum, as stated, by the weight ofthe suspended article. They are moved away from the drum by means of springs J, connected at one of their ends to cross-pieces, h, extending between the side portions of the guides I, and at their other ends to the brake-frames. lt will be seen that the brakes H are merely supported and guided by the guides I, and are unconnected thereto save by the springs J, and that the brakes have a movement in a direct line toward and from the drum. Of course I may use but one brake, if desirable.
What I claim as my invention, and desire to secure by Letters Patent, is
The combination, with aspring-drum, of an arbor upon which said drum is mounted, a frame, guides upon said frame, a brake supported and guided by said guides, a guide on said brake, a cord or chain wound upon the drum and passing over said lastmentioned guide to the article to be suspended, and a spring for moving said brake in one direction, substantially as specified.
JAMES D. GRISVVOLD.
