Definitions

  • My present invention is directed to the con struction of electric-lamp brackets, the object being to produce a jointed bracket or support for one or more incandescent lamps similar in appearance to the ordinary forms of lamp or gas brackets now in use, and arranged to contain the conducting-wires that convey the current to and from the lamp or the circuit-controlling devices connected therewith.
  • the invention consists in the arrangement of conductors at the joint or joints in said bracket, which prevents breaking or abrasion of the same when the bracket is turned, and the short-circuitin g or interruption of the circuit by which such accidents would be followed.
  • Figure 1 represents in elevation and part section a bracket constructed according to my invention
  • Fig. 2 an enlarged sectional view of the joint.
  • the bracket is shown as consist-ing of an arm, F, attached to a tube, E, pivoted byinsulated heads to contact-posts set in a plate, B. This latter is slotted and secured by bolts 0 D to an insulated plate, A, recessed for the reception of terminal contact-springs and a safety-wire, as fully explained in another application of even date herewith.
  • the hollow arm F ends in a cylindrical chamber, G, which is closed below by a screw-head, g.
  • This chamber forms a socket, within which fits the second joint of the bracket, and, though the construction of the latter maybe greatly varied, the form shown in the drawings is believed to be the' most convenient and reliable, and to it reference is accordingly made for an understanding of the invention.
  • G is a cylinder, the lower end fitting in chamber G and the top closed by a screw-head, g.
  • the second arm, L, of the bracket is fixed in any desired manner.
  • N is a tube, of insulating material, fitting the interior of cylinder G.
  • Two plates of insulating substance, 70 h are secured near the opposite ends of the cylinder,and a wooden pin, H, held between them.
  • the conductors are brought from the first joint or tube under the plate h, and are carried up through perforations therein. They are then formed in spirals about the pin 'H and carried through the upper plate, 70. From this they are led into the second section, L, and connected to the termi nals of a switch, N, by means of which the circuit is completed through the lamp M.
  • the wires are not affected by the movement of the sections of brackets, except in the spirals.
  • section F section F, section L, and insulated joining section or socket G, with conductors passing through the said sections and formed in spirals in the insulated joining section, as shown.
