MOUNTING FOR INCANDESCENT LAMPS.

RALPH ISTON ARMSTRONG, OF NEW YORK, N. Y., ASSIGNOR,'BY MESNE ASSIGN- MENTS, T WESTERN ELECTRIC COMPANY, INCORPORATED, A CORPOTION 015 NE Y0 1:1.
Specification of Letters Patent.
Patented May 30, 1216.
Application filed March 16, 1915. Serial No. 141,839.
To all whom it may concern:
Be it known that I, RALPH WILLISTON ARMSTRONG, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mounting for Incandescent Lamps, of which the following is a full, clear, concise, and exact description.
This invention relates to a mounting for incandescent lamps and more particularly to a mounting for incandescent lamps such as are used in telephone switchboards. its object is to provide a structure of this character which permits of the lamps being readily inserted in and removed from the mounting.
To this end, the invention contemplates a structure of the character set forth wherein lamp jacks, open at their rear ends, are mounted upon a board to register with apertures therein, whereby incandescent lamps may be inserted in the jacks from the rear of the board and held between the springs of the jacks, which springs also serve to conduct current to the lamps. The jacks may be provided with stops for limiting the forward movement of the lamps to within a short distance of the openings in the board, and the openings may be provided with lenses to carry the light of the lamps to the front of the board.
Referring to the drawings, Figure 1 is a perspective view of a lamp jack constructed in accordance with my invention and a lamp supported thereby; and Fig. 2 is a sectional view of the jack and its mounting plate or board, the lamp being also shown held be tween contact springs mounted on the jack.
The frame piece 10 may be punched from sheet metal. It is provided with rearwardly extending lugs 11, 12 adapted to support contact members or springs 13, 14:, the member 13 being attached to lug 11 by screws 22, 23 and member 14 to lu 12 by screws 24, 25. The member 13 is msulated from lug 11 by insulating strips 16, 17 and the member 14 from lug 12 by insulating strips 18,19.
The jack is mounted upon a board 26, which may be of wood, by means of lugs 27, 28 and screws 29, 30 entering perforations in said lugs and passing into the board 26. The incandescent lamp 15 is then inserted from the rear of the jack, terminals 20, 21 thereof contacting with the jack springs 13, 14, and is moved forwardly until its front end abuts against lugs 31, 32 projecting inwardly from the front of the frame piece 10. The jack is so mounted on the board 26 that the lamp 15 is'in line with a lens 33 mounted in a perforation in the board 26, the outer rounded end of the lens projecting slightly from the face of the support or board, whereby it not only renders the light emitted from the lamp visible from directly in front of the lamp, but also for some distance on either side.
What is claimed is:
1. In a device of the class specified, the combination with a support having an aperture therein, of a jack open at its rear end and mounted upon said support to register with said aperture, and an incandescent lamp adapted to be inserted from the rear of the jack and held between the contact springs thereof.
2. In a device of the class specified, the
combination with a support having an aper- A
