OMBINED SOCKET-COVER .AND"SHADE-HOLDER FOR ELECTRIC-LIGHT DEVICES.

Specification of Letters Patent.

Application filed April 26, 19-12. Serial No. 693,307.

To all whom it may concern: Y

Be it known that I, LAURITZ W. A nnR- SEN, a citizen of the United States, residing at Waterbury, in the county of New Haven electric lamp to a socket by a shade ring and a plurality of spaced attaching screws.

These latter are very liable. to cause the shade to crack under influences of heat and expansion, and the shade ring is very liable to become bent, hence it is difficult to maintain the shade concentric with the lamp, and the object of my invention is to overcome these objections.

In carrying out my invention, I provide a substantiallyconoidal cover of sheet metal adapted to receive and set over a keyless lamp socket, and the smaller end of this cover is apertured for the pipe of a chandelier, bracket or pendant, or for the electrio conductors alone. The larger end of the cover is formed with a circular edge and with a threaded collar secured therein. "-T his collar receives a threaded sleeve which sets within the rim of a shade or the glassware, while the circularedge of the cover comes outside the said rim, and thus the shade or glassware is held in position with an even all-around bearing of an adjustable char' acter.

In the drawing, Figures 1 and 2 are elevations, illustrating the use of the device of my invention. Fig. 3-is a vertical section, through the device of my invention and of about full size, showing a socket and lamp in position, and Fig. 4 is a detached section showing a detail bf modified form.

' Similar letters and numerals of reference indicate similar parts in all the figures.

a represents the socket cover of conoidal configuration apertured at the small end and provided with an edge a of circular form in cross section. These parts are integral and the circular edge may be, and preferably is, ornamented in any desired manner.

2) represents a collar fitting within the larger end of the conoidal cover and provided with a fiange'b by which the said collar is secured by solder or'rivets, or both, to the socket cover.

I have shown rivets at 2. I also provide a threaded sleeve 0' having a flange (1 represents the lamp socket, which in this particular device is keylcss.

d represents an incandescent electric lamp.

In Fig. 1, 6 represents a bracket, to which the device of ny invention may be connected, while in Fig. 2, f represents electric con- Patentetl Aug. 27, 19.1. .5.

ductors from which, and the socket connected therewith, h are suspended.

Fig. 1 indicates that the device of my inthe socket cover and shade :ventionmay be connected to a fixture, that is to a bracket, electrolier or other electric fixture, "while Fig. 2 represents that the same may swing from a ceiling or other support freely. Y

Fig. 3 represents the threaded collar 6, which is secured to the socket cover, as ex tending upwardly within the-socket cover, while Fig. 4 represents this collar as reversed, in other words, extending downwardly, but my invention is not limited by the position of the threaded Cover, as the same may occupy either position desired, according to the shade or glassware and the results to be obtained.

In connecting up the parts, as illustrated in Fig. 2, the electric conductors, connected to the socket, are to be passed through the aperture in the smaller end of the cover.

The rim of the shade or glassware is to be passed inside the circular edge of the cover and then the threaded. sleeve 0 is passed in side the shade or glassware and connected with the threaded collar so that the shade or glassware is held all around the rim with an even, firm but. not tight bearing.

Where the device of my invention is connected to an electrolier or a bracket, it may occupy the inclined position shown in Fig. l

or it may han directly down or extend directly upward, as the same is adapted substantially to any position. Where the socket cover is connected, as in Figs. 1 and 3, the pipe of a bracket or electrolier may extendthrough the aperture inthe smaller end of the cover, and the cover at this end may come u agamst a bead or other stop, as shown, an a clamping screw -may pass through the stop, or a nut on the inside of the cover upon this pipe may be employed,

all of which fastening devices it is possible to use with the device of my invention. In such instance, a socket is connected to the :free end of said pipe, the electric conductors passing through the pipe The device of my invention is particularly applicable to keyless sockets, asso many elec-- trical devices are employed nowadays where the light is operated by a switch rather than at the lamp sockets, and this is often necessary because of the height to which the lights are placed or the number of lights grouped 011 a circuit.

In the device of my invention, the unstable shade ring is entirely done away with,

4 as are also the plurality of spaced attaching screws which are so liable to injure the shade or glassware, and in the device of my'invent-ion, the shade or glassware is held at the rim by an even, gentle all-around bear ing which readily permits of the expansion and contraction of the shade or glassware without'liability of cracking the same. I claim as my invention: l. A combined socket cover and shade holder for electric light devices, comprising means removably co 'a' conoidal socket cover apertured at the smaller end for support, an enlarged lower portiomof the same to receive a shade, a supporting member connected thereto, and ected with the said member in an adjustable relation, for secur ing-Ktheshade or glassware in position.

ware and the rim of the shade fitting within the largerlower end of the socket cover.

. 3. A combined. socket, cover and shade holder for electric light devices, comprising a sheet metal socket'cover oflconoidalform -apertured at the smaller end fgirv connection with a means of support, and at; the larger lower portion provided-with an edge circularin cross section adapted to receive a shade, a threaded fla ed collar received concentricall with the 5 arger lower end of the socket cover and atlits flange securely fastened thereto, and a threaded sleeve adapted to be connected in an adjustable relation to the threaded collar, and said sleeve having a flange which, with the circular edge ofthe socket cover receives between them the rim of the shade or lassware and securely and adjustably hol the same.

Signed by me this 19th day of April, 1912.
