UNITED STATES PATENT OFFICE.
ALFRED DAIVES, OF CHELSEA, MASSACHUSETTS.
SUPPORT FOR INCANDESCENT ELECTRIC LIGHTS.
SPECIFICATION forming part of Letters Patent No. 394,680, dated December 18, 1888.
Application filed December '7, 1887. Serial No. 257,222. (No model.)
To aZZ whom it may concern.-
.Be it known that I, ALFRED DAWES, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Supports for Incandescent Electric Lights, of which the following, taken in connection with the accompanying drawings, is a specification.
In many factories, machine-shops, and similar places which are provided with electric light the lamps are suspended from the ceiling by a single insulated wire; but it has often been found desirable to have some means of moving the lamp into any desired position and securing it, so as to light up a certain portion of the work, and to accomplish this object is the aim of my invention; and it consists in certain novel features of construction, combination, and arrangement of parts, which will be readily understood by reference to the description of the drawings, and to the claims to be hereinafter given.
Of the drawings, Figure 1 represents an elevation of my improved support with a portion of one of the rods cut in section, and Fig. 2 represents a sectional elevation of the upper portion of the same.
In the drawings, A is a metal plate to be attached to any fixed object and provided with the hollow boss A, in which is mounted the ball B, provided with the threaded shank B, by which the hollow rod C is secured thereto, and in the outer end of said rod 0 is mounted a smaller rod, D, which may be readily adjusted to a greater or less distance from the ball-and-socket joint A B and secured in position by the set-screw a. The rods (l I) are provided with a series of eyes, I) 1;, through which the insulated wire 0 is passed, to the lower end of which is secured the electric lamp E. At some point above the lamp E the wire 0 passes through two eye-holes of a small piece of wood, (I, thus forming a loop the size of which may be increased when it is desired to raise the lamp to a higher level. The outer end of the chamber A of the plate A is threaded and provided with a recessed screw, F, by means of which the friction upon the ball B maybe regulated, said ball being fitted to a socket made in two parts, as the boss A and the saddle G, constructed and arranged to be movable one toward the other, so as to grip the said ball and create friction thereon, said parts being pressed toward each other by the spring l-I, interposed between the screw F and the saddle G.
The plate A is secured to the ceiling at a point directly over the center of the machine which it is desired to light, the friction upon the ball B having previously been regulated by adjusting the screw F, when it will be possible to swing the lamp into any position about the machine, the friction between the parts of the universal joint being such as to keep said support in any position into which it may be moved. By the adjustment of the rod D within the rod 0 a greater or less range of movement of the lamp laterally is secured, while by means of the take-up (Z any desired elevation may be obtained.
The advantages to be derived from my improved support are so obvious as to need no further mention.
\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is
1. In a support for incandescent electric lamps, the combination of an arm, a ball secured to said arm, a securing-plate formed with a screw-threaded socket for said ball, a saddle fitting over said ball within the socket, a screw-tlu'eaded plug adapted to be adjusted up and down in said socket below the upper surface of the securing-plate, and a spring interposed between the plug and the saddle, whereby the saddle is held in frictional contact with the ball and the rod is made to retaiu any position to which it is adjusted.
2. A support for incandescent electric lamps, com jn-ising' a securing-plate formed with a socket, a plug, a saddle, a spring interposed between said plug and saddle, a rod provided with a ball at one end and at the other with an open-ended tube, a rod adjust able within said open-ended tube, and sup ports for an electric wire, substantially as and for the purposes set forth.
3. In combination with an incandescent electric lamp, an arm, a ball secured to one end of said arm, a support for said lamp and its conducting-wire secured to the free end of said arm, a socket to receive said ball made in two parts, and a spring constructed and arranged to automatically press said parts tosubseribing witnesses; on this 5th day of De- Ward each other and clamp said ball, whereby "oembei', A. D. 1887.
the free end of said arm and the lamp suspended therefrom may be held in any desired 5 position, substantially as set forth. 'itnesses:
In testimony whereof I have signed my name to this specification, in the presence'of two ALFRED 'T)A\VES.-
N. C. LOMBARD, 'WALTER E. LOMBARD.
