"tain new and useful Improvements in Ceiling-Light Structures, of which the following' is a specification.

My invention relates to an improved ceiling light structure, comprising a canopy and a shade holder which are adapted to be separably interconnected to form a unitary device.

The primary object of my invention is to provide an improved ceiling light in which the canopy and shade holder portions are normally held together as an entity, but are capable of ready separation even by those unskilled in handling devices of this character.

A further object of the invention is to provide a simple form of connection between the canopy and shade holder which can be readily manipulated without the use of tools.

Still another object is to enable the canopy and shade holder portions, respectively, to be nested one within the other, whereby damage in shipment is obviated, and considerable numbers-0f the devices may be shipped and occupy a relatively small space.

The form of invention at present preferred by me is illustratively exemplified in the accompanying drawing, in which Figure 1 is a side elevational view of the ceiling light structure complete; Fig. 2 is a bottom plan view of the canopy portion; Fig. 3 is a top plan view of the shade holder; Fig. 4- is a vertical sectional view on the line-44 of Fig. 1, an electric light socket being shown in position; and Fig. 5 is an elevational view illustrating a number of the canopies nested.

In the drawing, 10 denotes the canopy which may have any desired contour, that shown in the drawing being more or less standard. The base of the canopy is provided with a substantially annular orifice 11,

and struck up from the wall of the canopy about the orifice 11 is-a series, preferably three, of fingers 12, which are upset to lie parallel with the base of the canopy, and to leave a small space between such base and themselves.

The shade holder is designated generally as 13, and may be of the conventional or standard form-shown in the drawing. The shade holder is open at both ends and at its head 1s proyided with a series of spaced cams 14 pro3ecting inwardly from the head of the shade holder. The'length of these cams corresponds substantially to the length .of the space between adjacent fingers 12 on the canopy.

15 are sockets formed in the shade holder through which screws are adapted to pass to engage a shade or other object (not shown) to be suspended fromthe shade holder.

16 denotes an electric light socket having the separable head 17 and the intermediate groove 18. As is well-known, the body 16 and head 17 of the socket are provided with screw threads by means of which these parts may be separated and secured together. I The device is operated in thefollowing manner :If it be desired to secure the canopy and shade holder, together, the shade holder is superimposed on the canopy in such manner that the cams 14 occupy the may be separated.

In the complete structure of Fig. 4 it will be noted that the base of the canopy as engaged by'the head of the shade holder pro- ]ects into the groove 18. In .this manner the lamp socket itself forms a supportfor the ceiling light structure, it being apparent that the shade holder cannot be removed from the canopy until the head 17 has been unscrewed from the body 16 of the lamp socket.

In Fig. 5 of. the drawing I have shown how a number of canopies may be nested for shipment or storage purposes. It will be noted that these canopies nest fairly closely and that a considerable number may be superimposed and occupy relatively little space.

What I claim is I In a ceiling light structure, the combination with an electric light socket having an Q I mower annular groove adjacent its base, of a canadapted to engage said fingers within said '1 opy having a circular flange adapted to progroove.

ject into the groove of the said socket, a In testimony whereof Ihave aflixed my sgries of fingers struck up from wall 0; signature in presence of two witnesses.

t e canopy and'upset to ie para e to sai flange within said groove, a shade holder FRANK ROBINSON having an upwardly projecting flange, and Witnesses:

a series of spaced cams at the upper edge of CLARICE FRANCE,

said last named flange, said cams being O'r'ro MUNK.
