To all whom it may concern-.-

Be it known that I, EDWARD S. a citizen of the United States, residing at ater-bury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Socket- Shells and Globe Holders for Electric Lights, of which the following is a full, clear, and exact description.

The object of this invention is to enable a manufacturer or dealer to supply the socket shells for electric lights in such way that globe-holders of any desired pattern may be applied to them expeditiously and eco11oinically as desired, or the shells may be sold in SANnnnsoN,

dependently of the globe-holders.

1n carrying out the invention, the socket shell is made with a circumferential bead near its end, and the globe-holder is made with an internal flange within which the beaded end of the shell is adapted to be placed, and over the edge of which the beaded end of the shell may be spun, or otherwise turned expanded or upset, in order to connect the shell and holder in such way that there shall be no relative movement.

in the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure l an inverted perspective view of one term of globe-holder; Fig. 2 is a per spective view of the socket shell. and Fig. 3

a longitudinal section of these two parts united. Fig; is an inverted perspective view of another form of globe-holder;- Fig. is a perspective view of the socket shell, and Fig. 6 1s a longitudinal section of these two parts united. Fig. 7 is a perspective low of one form of holder having a plain flange.

The socket shell 1 has oneend made with a circumferential head 2, leaving beyond it a plain cylindrical extension v3; Such a shell is ada ted to be used with ordinary electric light c evices, and may be sold as such.

In order that manufacturers or dealers may suit the desires or fancies ofpurchasers,

with respect to the style or finish orconstruction of globe-holder to be used on the selected style of socket shelhl provide the .globc-holder l with the ordinary flange 5,

containin screws 6, as usual, to enga e the globe, an also provide said holder with an the combined shell and globe-holder as shown in Fig. 7, this flange may be made made with the edge notches as previously described. The notchless flange shownin Fig. 7 is applicable to either or any form of holder.

In order to connect the socket shell with the desired globe-holder, itsbeaded end is inserted in the opening surrounded by the internal flange, and such end is enough longer than the depth of the flange to project slightly beyond it, and when thus arranged, the projecting end of the shell is spun, expanded, headed up or otherwise upset or turned over the edge of the internal flange, and if such edgebe notched, this treatment causes the end of the shell to dig into said notched edge; in either case, a very firni union or interlocking of the parts is secured. 5

By the invention described, a manufacturer or dealer is enabled to use the regular socket shell without any change if the globe holder is wanted on the socket. All that is necessary to fasten the socket and globe,- holdcr together, is a small spinning tool and adrill press, although other machine or even hand tools may be employed for this purpose. Moreover, the lobe-holder is held very firmly on the shel and there is no chance of its becoming loose by relative rotary movement or otherwise; and finally, present a very neat appearance.

The circumferential head on the socketshell serves to limit the extent to which the shell projects within the internal flange, and to this extentand in this manner serves as a stop. The invention, however, is not: limited to the use of such bead.

The drawing, shows the notches 8 some what exaggerated in depth, and this is done merely for illustrative purposes. In actual practice these notches need be but quite shallow, so long as they present surfaces or pertions capable of being engaged by the spun over or headed up edges of the shell; and as already stated, the internal flange maybe made Without notches in its edge.

What I claim is 1. A socket shell and globe-holder for electric lights, comprising a shell, and a globe-holder having an internal flange, the shell adapted to be inserted within said flange with its thus inserted end extending beyond the inner edge of said internal flange and the edge of the extended portion of the shell turned over and thus interlocked with the flanges edge.

2. A socket-shell and globe-holder for electric lights, comprising a shell, and a globe-holder having an internal flange provided with edge notches, the shell adapted to be inserted Within said flange and projectbeyond its inner edge and its edge turned over and interlocked with said notches, whereby relative rotary movement of the shell and holder is prevented.

3. A socket shell and globe-holder for electric lights, the shell having a beaded end to limit its inward movement with relation to the globe-holder, and the globeholder having an internal flange provided with a notched edge, the beaded end oi the shell adapted to be placed within the internal flange so that its inner end projects beyond the edge of the flange and the edge of said projecting end turned over and engaged with the notched edge of said internal flange, whereby relative rotary movement of the shell and holder is prevented.

4. A socket shell and globe-holder for electric lights, comprising a shell having one end provided with a stop, and a globeholder having an internal flange with a notched edge, the stop end of the shell inserted within the internal flange and its said inserted end extending beyond the edge of the flange and the shells edge turned over and thereby engaged with the notched edge of said flange, whereby relative rotary movement of the shell and holder is prevented.

In testimony whereof I have hereunto set my hand this 17th day of March A. D. 1910.

EDWARD S. SANDERSON.
