NORMAN MoLEOD, OF DETROIT, MICHIGAN.

ELECTRIC-LIGHT HANGER.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed December 4, 1909. Serial No. 531,298.

To all whom it may concern.

Be it known that I, NORMAN MCLEOD, citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Electric -Light Hangers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to hangers for electric lamps.

It has for its object an insulated hanger adapted to be used for suspending metallic filament lamps.

The metallic filaments in use at the present time are quite fragile and liable to be broken by sudden shocks and jars, and the object of this invention is to produce a hanger or a suspension bracket which will serve as a cushion to prevent the harsh vibration occurring in some places where these lamps are used or where it is desired to use them.

' In the drawings :-Figure 1, is a perspective of the hanger with the lamp connected thereto. Fig. 2, is an elevation of the hanger. Fig. 3, is a vertical cross section of the hanger, taken at the line 3-3 of Fig. 2. Fig. 4, is a vertical cross section of the supporting pieces of the hanger.

The structure employs a metallic coupling 1 provided with a terminal 2 which is threaded internally and is held to the suspension rod 3 by diametrically opposed integral hangers 4. The upper end of the coupling 2 is open and communicates with a passage through the neck 4 to enable the wires 5 and 6 to lead through the coupling to the end of the socket or to the end of the tube 7 which acts in conjunction with the hanger to suspend the socket 8. The suspension rod 3 engages within the insulating bushing 9 into which it reaches by an opening 10 in the bottom of the bushing. The bushing is covered by a disk 11 and both bushing and disk are held in place by a casing 12 which is suspended from any suitable fixed support 13. The inclosed end of the suspension rod 3 engages in a holding nut 14 that rests on the upper end of the spring 15, whose lower end is supported by the flanges that surround the opening 10 and form the bottom of the insulating bushing 9. The rod 3 is thus completely insulated from the metallic case of the hanger by which it is itself suspended, and is protected from all ground connections, and is itself supported on a cushioning spring that cushions the suspended light fixture and preserves it from vibrations and shocks incident to rapid vibration of the upper parts of the suspension device and the consequent vibration of the case 12 and its suspension member 13.

What I claim is A cushion suspension hanger for electric lamps, having in combination a suspension case having a large aperture in its bottom wall, an insulating cup fixed therewithin, said cup being provided with an aperture axially concentric with that in the bottom of the case but of smaller diameter, a suspension rod engaging with its headed upper end within said insulating cup and with its lower end projecting through the aperture in the bottom thereof, and a cushion spring interposed between the insulating cup and the suspension rod, whereby the rod is yieldingly held in raised position with respect to the case and insulating cup.

In testimony whereof, I sign this specification in the presence of two witnesses.

NORMAN MOLEOD.

CHARLES F. BURTON, VIRGINIA C. SPRATT.
