' 11' Claims. (01. 240-10) This invention relates to portable electric lighting. outfits of the type used for Christmas tree ornamentation and for similar illuminated display purposes. More particularly, my invention relates to an improved construction for the electric light sockets used' with such lighting outfits.

One of the objects of my invention is to provide an electric light socket construction of the character described, having .novel means for attaching said sockets to a branch of a Christmas tree, or to any other support.

Another object of my invention is to provide an electric light socket of the character described and novel mounting means therefor, which shall comprise relatively few and simple parts, which shall be economical to manufacture, easy to assemble and which at the same time shall be highly eflicient for the purposes intended.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of.

this invention,

parallel to the axis of the shell.

Referring now in detail to the drawing and particularly to Figs. 1 to 5, there isshown an a electric light socket of the type well known in the art, used on Christmas tree or similar portable display lighting outfits, and provided with a husk 20, of. insulating material and lamp 2| and suitable lead wires 22 connected tothe'socket, in the manner well known in the art.

The outer wall of the husk 20 is provided with a relatively narrow raised portion ,23, which may be integral therewith and which may be disposed r The longitudinal edges 23a of the portion 23 may be inwardly tapered as shown for reasons which will soon become apparent.

For attaching the socket to any support such as for example the branch B of a Christmas tree, I have provided an attaching member 30, (see Fig. 5) comprising a strip of resilient material, bent over on. itself to form two substantially parallel arms 3| and 32 interconnected by the loop 33. The arm 32 is preferably made fiat to overlie the surface of the portion 23, and is provided with pairs of spaced tabs or

guides

34 and 35, which may be formed of integral extensions bent over to define a guideway adapted to slld ably receive therein the raised portion'23, with the

guides

34 and 35 snugly fitting the tapered edges 23a of said raised portion to hold the member 30 frictionally captive on the socket.

The member 30 may be resiliently hooked over a branch B, the said branch being received between the arms 3| and 32. To insure a more positive gripping action of the member 30, either of the arms 3| and 32, such as for example the arm 32 as shown, may be provided with bent over side extensions 36 between the

guides

34 and 35, the free edges of which are serrated as shown.

In Figs. 6 to'8 I have shown a modified form of my invention, in which the'attaching member 30', instead of having the arm 32 provided with the

tabs orguides

34 and 35, is provided with a pair of continuous guides 40, which are substantially contiguous with the length of the arms 32. The said guides 40 are angularly bent to conform to the tapered walls 23a, and are adapted to be slidably and frictionally received on the raised ing member 50 comprises a pair of arms El and arm 52 is provided with angularly bent over edge portions 54, provided with serrations to provide better gripping action for the member ill. For attaching the member ill to the socket, I provide an independent relatively rigid flat member 55, freely rotatably attached to the arm 52 by means of the pivot 56. The member 55 is provided with angularly bent over longitudinal edges 51', corresponding to the tapered walls 23a of the raised portion 23 and adapted to be frictionally received thereon.

It is seen from the above described construction that the member 50, after being attached to the socket, may be rotated about the pivot 58 to assume any desired angle before or after attachment to a branch.

It is also noted that the attaching members Ill, or may be applied to the type of socket in which there is employed a bottom cap 60 which is screwed to the husk 20 and in such position serves to prevent downward sliding or undesired removal of the

members

30, 30' or 50.

If desired, the arm.32 may be provided with one or more struck out portions defining pointed projections I0 adapted to become embedded in the top surface of the portion 23 to prevent the downward sliding of the member 30. Also, if desired, detents H may be provided in the top surface of the portion 23 adapted to receive the projections 10 therein.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
