COMBINED SOCKET-COVER AND SHADE-HOLDER.

Specification of Letters Patent.

Patented June 13, 1916.

Application filed November 13, 1915. Serial No. 61,202.

To all whom it may concern Be it known that I, LAURITZ W. Ano nt- SEN, a citizen of the United States, reslding at lVaterbury, in the county of New Haven and State of Connecticut, have inventeda certain new and useful Improvement in Combined Socket-Covers and Shade-Hold ers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to electric light fixtures and more partlcularly to a combined socket shell cover and shade holder, one object of the invention being to dispense with the use of screws for the purpose of supporting or holding the shade.

Another object of the invention 1s to provide a shade holder of this character in combination with a socket shell cover, the parts being ofsuch construction that they can be quickly and easily assembled and connected to perform the combined function of covering the socket and supporting the usual construction of open glassware or shade.

With these objects in view the invention consists in the various novel features of construction and combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure. 1 is a perspective view of the complete device constructed in accordance with my invention; Fig. 2 is a view showing the manner of assembling or connecting the parts, a portion of the shade being shown in section; Fig. 3 1s a vertical sectional view of a combined socket shell and shade holder embodying my invention, the socket and shade connected thereto; Fig. 4 is a detail perspective view of the socket shell cover; Fig. 5 is a detail perspective view of the shade supporting ring; and Fig. 6 is a detail perspective view of the connecting collar.

In the practical embodiment of my invention I employ a shell A which is adapted to receive and envelop the usual incandescent lamp socket, the upper end of the shell be ing apertured topermit the passage of the conduit tube or socket shell bushing, as the case may be. This shell A may be slotted or apertured at the side, to receive a switch key or a chain guide of the pull socket. The shell is preferably constructed with a bead A adjacent the lower end, and below said bead, the sides of the shell are indented or grooved at diametrically opposite points A and it will be understood that any additional number of indentations or grooves can be produced if so desired.

The open glassware or shade C is supported upon an outwardly flared ring D which fits'upon the inside of the mouth of the shade as shown, the upperportion of sald ring being adapted to project above the mouth of the shade, andis provided with screw threads D, this threaded portion being also indented at diametrically opposite points as indicated at D", said indentations being adapted to fit into the indentations or grooves A when the ring D is pushed up so as to fit over the lower end of the shell A, the bead A serving to limit the upward movement of the ring, and the indentations D engaging the indentations A hold the ring D against rotation, and for securing the ring'in fixed relation with reference to the shell there is provided a collar E, the upper portion of which is screw threaded as shown at E to engage the threaded portion D of the ring D, while the lower portion is shouldered or flanged as shown at E to envelop the bead or edge of the shade and conceal the same from view. The eX- treme upper end of the threaded portion E is constructed with an inwardly projecting flange E which is adapted to engage and rest upon the head A and limit the downward movement of the clamping collar.

In operation the sup orting ring D is inserted within the mout of the shade C to be supported and this ring D is then slipped over the lower end of the shell A as shown in Fig. 2, and the clamping collar E is then moved down and given a few turns so as to engage the threaded upper end of the supporting ring and thereby securely connect all of the parts together.

It will thus be seen that I provide exceedingly simple and highly efficient combined socket shell cover and shade holder which completely eliminates the use of screws for supporting the shade and connecting the various parts together.

Having thus described my invention, what I claim 'is:

1. In a device of the kind described, a shell adapted to receive and envelop a socket, a continuous shade supporting device adapted to engage the interior of a shade and also engage said shell, and means adapted to combine said parts together and engage the exterior of the shade.

2. In a device of the kind described, a shell adapted to receive and envelop a socket, a shade supporting ring having its upper end shaped for engagement with the lower end of the shell, and a clamping collar adapted to engage the upper end of said shade supporting ring and embrace the bead or mouth of a shade carried by said ring as set forth.

3. In a device of the kind described, a shell adapted to receive a socket, the lower end of said shell being headed and grooved, a shade supporting ring having its upper end threaded and indented and adapted to engage the grooved end of the shell, and a clamping collar having a threaded portion adapted to engagethe threaded portion of the shade supporting ring, the lower portion of said collar being adapted to embrace the bead or mouth of a shade carried by said ring.

4:. A device of the kind described comprising a shell adapted to receive a socket, said shell being beaded adjacent its lower end, and provided with indentation below said bead, a flared ring having its upper end threaded and indented, said threaded and indented portion of ring being adapted to engage the indented portion of the shell, and a collar having a threaded portion adapted to engage the threaded portion of the shade supporting ring, the upper end of said threaded portion being provided with an interior flange adapted to engage the bead upon the shell, the lower portion of said collar being shouldered and adapted to embrace the bead or mouth of a shade arranged upon the flared shade supporting rlng.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.

LAURITZ V. ANDERSEN.
