TOOL FOR ELECTRIC-LAM? BOCETS.

Specification 0! Letters Patent.

Patented Dec. 8, 1908.

To all whom it may concem: 1

Be it known that I, GILBERT W. GOOD- mnen, a citizen of the United States of America, and a resident of the city of Bridgeort, in the county of Fairfield, in the State of onnecticuahave invented a certain new and useful 1m roved Tool for Electric Lamp Sockets, 0 which the following is a specification.

My invention consists of an improved tool for use in fitting electric lamp sockets in place upon fixtures or other sup orts, the tool being more especially use 1 where sockets are to be introduced within ornamental fittings or husks.

In the accompanying drawings Figure 1 is a side elevation showing the tool about to have its operating head introduced into a cap 0; Fig. 2 1s a corresponding view showing the tool in lace; Fig. 3 is an end view of the tool head; ig. 4 is a sectional view of the tool car g a socket shell.

the tool.

tool comprises a head A and handle A with cross-piece a, and a hole a) is formed through the tool head and handle for a purpose explained hereinafter.

The head of the tool is preferably made of the circular outline shown to fit the interior of the flanged part of a socket cap, and a number of lateral projections 19, p, are formed on the tool head to engage openings or recesses in the flange of the socket ca In the present instance I have shown t e tool as especially constructed for use in connection with the electric lamp socket formin the subject of my Patent No. 872,283, dated November 26th, 1907, and which the flange of the cap is uniformly wrinkled or corrugated, and accordingly the periphery of the tool head is formed with projections p spaced to correspond with an fit into the recesses formed by the corrugations c in the flan e of the cap C. I

V hen the tool head is inserted in the cap, the two are locked together rotarily, so that the wire man'can readily insert the cap into the bottom of an ornamental husk and screw it up on the threaded pipe end by means of The wires projectin from the pipe end may be received into the ole a, formed hea in the head and handle of the tool, and therefore twisting of the wires will be avoided in screwin up the ca I pre or to form th than the flange of the cap and to form marks m on this rear extension in line with the projections p, in order that when the wireman is giving the last turn to the ca on the pipe he may stop with one of these ines n 0 pcsite the center line of the slot left in the usk for the reception of the ke of the socket. Then in putting the socket s ell and contents into the cap, the wireman will know that the key will be in line, as it should be, with one of the corrugations c in the cap, and the socket will pass that much more directly and easily into the cap, and the latching means will at once snap into engagement. I recess out the front en of the tool head, as indicated at a in Fi 4 to receive the outer end of the shell S an the projectin end of the insulating lining s, when the bee s of the shell comes to rest on the annular shoulder or flange y thus formed in the end of the tool so that the thrust needed to ush the shell into the cap after the latter as been screwed onto the i 6 within a husk ma thus be taken by the s e S, instead of by tile end of the lining, as would be a t to be the case if the shell were put in by and. Pressure applied to the front end of the lining will mar its appearance and will also force the lining to project at the back of the shell and interfere with the fitting of the shell into the cap.

I claim as my invention 1. A tool for electric lamp sockets, comprising a handle and a head with a hole through the head for the wires, the head e head of the tool deeper adapted to fit into a socket cap and having parts to en age the ca rotarily.

2. A tool for electric lamp sockets, comprising a handle and a circular head to fit,
