LIGHTING FIXTURE.

Application filed June 5,

To (ZZZ whom it may concern:

Be it known that I, VVILFRED B. GODDARD, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Lighting Fixtures, of which the following is a specification.

The invention relates to electric lighting fixtures and particularly to devices for supporting the electric switch within the fix ture.

An object of the invention is to provide a pull switch within the fixture arranged on the axis of the fixture, so that operation of the switch will not cause the fixture to swing. 7

Another object of theinvention is to provide a mounting for a pull switch between the upper and lower shells of the fixture.

The invention possesses other advantageous'features, some of which, with the foregoing, will be set forth at length in the following description, where I shall outline in full, that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. In said drawings .lyhave shown one embodiment of my invention. but it is to be understood that I do not limit myself to such form, since the invention, as set forth in the Claims, may be embodied in a plurality of forms.

Referring to said drawings Figure 1 is an elevation of a ligl'iting fixture equipped with the device of my invention, the fixture being partly broken away to show the arrangement of'the device.

Fig. 2 is an elevation, on a larger scale, of the device in its environment.

Fig. 3 is a perspective view of the device.

My invention relates to electric lighting fixtures and particularly to pendant fixtures, comprising a body formed of upper and lower shells 2, 3, upon which lighting elements 4 are mounted. It is frequently desirable to control the flow of current to the lighting elements by a pull switch operated by a cord or chain depending from the ture. In the past, these cords or chains 1922. Serial No. 565,882.

have depended from the side of the fixture, so that when they were pulled, the fixture would be started swinging. These fixtures are frequently suspended from the ceiling by chains, so that they readily swing and the swinging of the lighted fixture is very objectionable. In accordance with my invention I arrange the switch and the pull chain in the vertical axis of the fixture, so that there is no tendency to swing the fixture. Further, the switch is rigidly supported, so that the strain produced by pull ing the chain is not transmitted to the shells.

In'the drawings I have shown a fixture supported from the ceiling by a chain 5, but a rigid support, such as a pipe or tube, is often used. The chain 5 is attached at its lower end to a. socket 6, bearing against or otherwise associated with the upper shell 2 and engaging the socket and disposed between the shells 23, is a conduitor pipe 7, through which the electric wires pass. Secured to the lower end of the conduit 7 is a hickey 8, having on its lower end, a threaded stem 9 which extends through an aperture in the center of the lower shell 3. A nut 12, screwed onto this stem supports the lower shell in position. The hickey comprises a frame having a threaded apen ture in its top to receive the lower end .of the conduit pipe 7 and is provided with a transverse wall or partition 13, upon which a pull switch casing 14 is mounted. The casing 14 is provided with a hollow threaded stem 15 extending through an aperture in the partition and the casing is held in place by a nut 16 engaging the stem. The pull chain 17 extends through the stem 15, the stem 9 and the hollow nut 12 and is provided on its lower end with a suitable grip or tassel 18.

The switch supporting hickey is thus dis posed between the shells in line with the axis of the supporting chain and is directly attached to the chain, so that the pulling force is transmitted through to the chain and is not effective on the shells.

I claim:

1. In an electric lighting fixture, a hickey, an apertured partition 'wall in said hickey, an electric pull switch mounted on said wall and an actuating element for said switch a nut engaging said stem and securing the extending downward through said wall and switch to the partition, and an actuating 10 hickey. element for the switch extending downward 2. In an electric lighting fixture, a hickey, hrough said stem and hickey. an apertured, horizontal partition wall in In testimony whereof, I have hereunto set said hickey, an electric pull switch mounted my hand. on said wall, a stem on said switch extending through the aperture in the partition, XVILFRED B.
