ADJUSTABLE BODY WITH CLUSTER Filed Feb. 18, 1925 Patented Oct. 15, 1929 warren stares PATENT orrics CHARLES E. wrnrn, or warnanuar, CONNECTICUT, assrenoa To THE WATERBURY METAL wanes COMPANY, or WATERBURY, oonnno'rrou'r, A CORPORATION or CONNECTICUT ADJUSTABLE BODY \VITH CLUSTER Application filed February 18,1925. Serial No. 9,921.

This invention relates generally to electric light fixtures and more particularly to an electric lamp having a cluster of lights; the object being to provide for the quick and easy adjustment of the cluster with'reference to the lamp shade and base.

For some time past, electric lamps have been provided embodying a base, standard, and shade together with a cluster of lights arranged at or nearthe upper end of the standard and adjacent to the top of the shade.

In most electric lamps these clusters are stationary, that is there is no adjustment whatever, while in other constructions the individual sockets are separably adjustable, and

in still other instances the shade has been adjustably mounted with reference to the cluster and standard.

My present invention provides a. still further adjustment and consists in providing a body or shell adjustable upon the standard. and carrying a cluster of lights, this body or shell being quickly and easily adjusted and secured at any desired point within the limits of adjustment, for the purpose of quickly and easily shifting the cluster of lights as a whole, with reference to the lamp shade andrbase.

The invention also includes certain details of construction hereinafter more fully described and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a side elevation of a lamp embodying my invention, one adjustment of the hollow body or shell being shown in dotted lines; Fig. 2 is a vertical longitudinal sectional view; and Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2.

In carrying out my invention I employ a lamp standard A provided with a base B and having a shade C arranged upon the upper end thereof and secured by means of a knob D which screws upon the threaded projecting member E extending upwardly from the end of the standard and passing centrally through the shade C.

This is merely one method of arranging the shade upon the end of the standard, and it will be understood that any other suitable construction of shade supporting or holding means may be employed.

The standard A is hollow or has a passage F extending therethrough for the conductor Wires Gr. Mounted upon the standard A is the hollow shell or body H which is adjustable up and down upon the standard Within certain limits, and is secured at any desired point of adjustment by means of the set screw I passing through the lower end of the body or shell H and binding against the standard.

The body or shell H is preferably constructed with a detachable cover H which has a threaded connection with the upper end of the hollow shell or body H, but any other means of uniting the body and cover may be employed.

This hollow body or shell H is perforated at definite points for the attachment of the nipples K to which the sockets L are connected and the conductor wires G are brought out through a lateral opening M in the standard and carried to the sockets L through the nipples K in the usual manner.

This lateral opening M in the standard A is within the hollow body or shell and is completely concealed thereby. The adjustment 7 of the hollow body or shell is, therefore, limited to the extent that its movements up or down do not expose the lateral opening in the standard.

Within this range, the body or shell is quickly and easily adjusted by simply releasing the set screw I, moving the shell up or down and then re-tightening the set screw. As the shell moves up and down it carries with it the cluster of lights as a whole and it will be understood that any desired number of lighitls pan be connected to the adjustable body or s e l.

The removable cover to'the body or shell permits the quick and easy wiring connections to be made after the body or shell has been arranged upon the standard.

The cover is then slipped over the end of the standard and connected to the top of the body or shell and the shade is then arranged in place upon the upper end of the standard. The lamp is then ready for use, it being of course understood that the sockets are connected to the body or shell when the wiring Connections are made.

It is obvious that with a lamp constructed as herein shown and described the entire cluster of lights can be quickly and easily shifted as a whole, with reference to the lamp shade and base, as desired.

Having thus described my invention, what I claim is:

1. In an electric lamp, the combination with a standard having a central passage provided with a lateral opening, of a body vertically adjustable upon said standard and enveloping said lateral opening, sockets connected to the body, conductor wires passing through the standard to said sockets, and a shade arranged upon the upper end of said standard.

2. In an electric lamp, the combination with a hollow standard having a lateral opening, of a hollow body having a detachable cover and provided with nipples, said standard passing through said body and cover, said body being vertically adjustable upon said standard and covering the lateral opening, sockets connected to said nipples, and conductor wires passing through said standard and lateral opening and through the hollow body and nipples to the sockets.

In testimony whereof, I hereunto affix my signature.

CHAS. E. WVIRTH.
