SUSPENSION DEVICE FOR LAMPS.-
SPECIFICATION forming part of Letters Patent No. 323,294, dated July 28, 1885.
Application filed December 12, 1884. (No model.)
To aZZ whom it may concern.-
Be it known that I, EDWIN H. BROWN, of Brooklyn, county of Kings and State of New York, have invented a certain new and useful Improvement in Suspending Devices for Lamps and other Articles, of which the following is a specification.
I will describe a suspending device embodying my improvement, and then point out the novel features in claims.
In the accompanying drawings, Figure 1. is a view of a suspending device embodying my improvement, partly in section. Fig. 2 is an inverted plan view of the same, and Fig. 3 is a sectional view of a modification thereof.
Similar letters of reference designate corresponding parts in all the figures.
A designates a loop, which may be hung on a hook or other appendage of a ceiling or other object. This loop is connected to an arbor, B. As shown, the arbor B has at the upper end a neck, a, or portion of smaller diameter than the portion below it, and the loop Ahas a hole or eye, I), which receives the neck a within it. The neck is externally screwthreaded, and has a nut, 0, applied to it. The nut O, as shown, has a cylindric body, 0, which extends into the hole or eye I) of the loop A, and a flange which extends above the lower portion of the loop A. After the nut has been applied to the neck a of the arbor the end of the neck will preferably be upset to preclude the nut from coming off. Thus the loop and arbor are secured together with a swivel-joint. The arbor can be turned around relatively to the loop without becoming detached from it. Immediately below the neck a of the arbor B the arbor has a cylindric body, 0. Said body is provided with longitudinal grooves, g. I have shown the body 6 as extending through a sleeve or tube, a. At the upper end said sleeve is provided with a laterally-extending flange or collar, a rigidly secured thereto. At its lower end the sleeve is provided with a head or flange, f. The head or flange f has a groove, f, extending circumferentially about it.
D designates a frame, shown as having a portion, (1, extending approximately parallel to the upper part of the drum E, and down- -drum is rotated in one direction, the spring t, between which are wound upon it cords or chains F, whereby a lamp or other article may be suspended. This drum, as shown, is closed at the top with the exception of a central hole enabling it to fit upon the sleeve to. It is provided at the bottom with a crosspiece, j, through a central aperture in which also extends the sleeve a. Said cross-piece is rigidly secured to the drum. Instead of one of such cross-pieces, I may use two or more. The head or flange f is below the cross-piecej, and in this example of my improvement is uncon- 7o nected therewith. The drum E is adapted to rotate about the sleeve a, and is capable of a vertical movement upon the arbor B. The drum is rotated by the unwinding of the cords or chains F. A counterbalance is intended to be combined with the drum for the purpose of resisting the unwinding of the cords or chains, and thereby sustaining the article attached to the cords or chains. I have shown in this example of my improvement a counter balance, G, consisting of a convolute spring. This spring is coiled around the sleeve a. One end is secured to the sleeve (4 by a rivet or otherwise. The rivet preferably extends through the side of the sleeve a, thereby forming a projection within the sleeve entering the groove 9 of the body of the arbor. The other end of the spring is fastened to the interior of the drum by rivets or otherwise. When the will be coiled up more closely. When relieved of the force which coiled it and kept it coiled up, it uncoils and rotates the drum in the reverse direction.
H designates levers fnlcrumed at h to the downwardly-extending arms d of the frame D. The outwardly-extending ends of said levers are provided with guides h, which, as here shown, consist of pulleys over which the cords or chains F pass to the article to be suspended. ICC
' manner.
The inwardly-extending ends of said levers enter the circumferential groovef of the head or flange f. It will be seen that the Weight of a lamp or other article upon the cords or chains F will operate to cause the inwardlyextending ends of the levers H to exert an upward pressure upon the drum, by which means the drum will be moved toward the portion (1 of the frame D. As shown, the portion d has upon the under side a circular piece or ring of india-rubber, leather, or like material, It, secured thereto in any suitable This ring forms a brake, which will act upon the top of the drum when the drum is moved up' sufficiently far.
I designates a spring (shown as helical) arranged about the arbor B, within a recess upon the under side of the portion (1 of the frame D, and bearing upon the upper surface of the drum. This spring, when the drum is not otherwise actuated, will keep the drum so depressed that it will not be subjected to the action of the brake. The drum may, however, be forced upwardly against the resistance of the spring, so that it will be acted upon by the brake. A similar result to that produced by the spring I would ensue through the action of the counterbalancing convolute spring, by reason of the tendency of the coils to assume a position in one and the same plane transverse to the axis of the drum. To enable it to do this, the inner end of the spring will have to be attached to the arbor B lower down than the position the outer coils will occupy when the drum is raised, as shown more clearly in Fig. 3, in which the inner end of the spring is secured to the arbor B by means of a screw or pin extending through a slot in the sleeve or tube a.
I have shown in Fig. 1 still another means of accomplishing a like resultnamely, springs S, one of the ends of each of which is secured to this arm d of the frame D, and the other to the outwardly-extending ends of the levers H. The tendency of these springs is to draw the outwardly-extending ends of the levers upward, and consequently to depress the inwardly-extending ends of the levers and move.
the drum downward.
When the weight of the lamp or other article is removed from the cords or chains F, the drum will be relieved from the action of the brake, and it may then rotate freely to rewind the cordsor chains.
Obviously the sleeve a may be omitted injunction with each cord or chain.
All the various parts of this suspending device maybe made of metal, except, possibly, the piece R.
On the 6th day of December, 1884, I filed an application for Letters Patent No. 149,654, wherein I showed and described a suspending device having an arbor, a drum adapted to rotate about said arbor, cords or chains wound upon the drum and passing thence over guides downwardly to suspend any desired article, a convolute spring being em ployed within the drum to counterbalance a suspended article, and a friction-brake being combined with the drum in such manner as to be rendered effective by the weight of the suspended article. Thus, generally described, the suspending device which formed the subject of my application No. 149,654 bears a resemblance to the suspending device which is the subject of my present application. In thesuspending device which is the subject of my application No. 149,654 the guides for the cords or chains are arranged upon a frame which is supported upon the arbor independently of the drum, and at such elevation relatively to the drum, that when the cords or chains are pulled down by the weight of an article attached to them they will pull the drum upward to a friction-brake which is arranged upon saidframe.
In one example of suspending device show in my said application No. 149,654 the cords or chains produce the upward movement of the drum by acting directly upon the flanges of the drum. In another example, however, they are shown as operating to elevate the drum by passing around movable pulleys connected to a yoke extendlng below the drum.
I do not in my present application lay any claim to the combinations of parts just hereinbefore described as distinctive of my said application No. 149,654.
What I claim as my invention, and desire to secure by Letters Patent, is-
, 1. In a suspending device for a lamp or other article, the combination of an arbor, a frame supported by said arbor, a drum adapted to rotate and move lengthwise upon the arbor, a brake above the drum,a cord or chain wound upon the drum, and a lever fulcrumed between its ends to the frame extending at one end under the drum and provided at the other end with a guide for the cord or chain, substantially as described, whereby,when the weight of the lamp or other article is brought to bear upon the cord or chain, it will operate through the lever to cause the drum to move upwardly to render the brake effective, and when said weight is removed from the cord or chain the brake will be released.
2. In a suspending device for a lamp or other article, the combination of an arbor, a frame supported by said arbor, a drum adapted to rotate and move lengthwise upon the arbor, a brake above the drum, cords or chains wound upon the drum, and levers fulcrumed between their ends to the frame, extending at IIO one end under the drum and provided at the and when said weight is removed from the other end with guides for the cords or chains, cords or chains the brake will be released.
substantially as described whereby when the T Weight of the lamp or other article is brought EDWIN BROWI 5 to bear upon the cords or chains, it will oper- Witnesses:
