LOOK FOR INCANDE'SCENT LAMPS.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed May 16,1906. Serial No. 817,196.

vented certain new and useful Improvements in Looks for Incandescent Lamps, of

which the following is a specification, refer,

ence being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in. globe-holders; and

the invention aims to provide a novel form oflock for holding a" globe inengagement with its socket,- whereby the same cannot be stolen or fraudulently removed from its 1 socket. 'To this end I have devised a simple and inexpensive .globeeholder which can be easily and quickly placed in engagement.

with a globe and'loc'ked in engagement with the socket of said globe, whereby the globe cannot'be removed until the holder =has been detached from the socket, and in this connection the holder is particularly vsulapted for -incandescentalightv .,globes,=.= -whichoften stolen from their sockets and used in connection with other sockets.

in constructing my improved holder Iaini.

to prowixle ws'iti-veand' reliable sneans for embracing an incandescent-light bulb and retaining it within its socket, said means in in the claims, and referring to the drawings accompanying this application like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of my improved globe-holder. Fig. 2 is a front elevation of the same. Fig. 3 is a plan of a cap used in connection with the holder. Fig. 4 is a detail sectional view of the same. Fig. 5 is a detail sectional view of the retaining band or ring used in connection with the holder. Fig. 6 is a detail sectional view of a portion of the holder. Fig. 7 is a perspective view of the retaining band or ring.

In the accompanying drawings, I have illustrated a conventional form of electricbulb socket 1 as containing a bulb or globe 2, said bulb or globe having a conventional form of nipple 3 at its large end.

My invention resides in providing the end of the socket 1 with a cap 4,1saidca being provided with a central opening 5 an with a split 6, the split edges of said cap being rovided withupwardly-extending ierced 7 7, whereby a seal 8 or a similar ock may be placed in engagement with the pierced lugs 7 to lock the cap 4 upon the socket 1. The cap is provided with diametrically opposed openings 9 :9, and in said openings are mounted the ends 10 10 of a piece of wire 11, said wire extending around the large end of the bulb or globe 2 to retaiinsaidbulb or globe within the socket 1.

To prevent the wire 1 1 from being removed from the globe orbulb 2, the wire intermedi ate'its endsis flattened, as at 12, and provided witlian opening 14 to receive the'nipple .3 upon the rear end of the bulb or globe 2. A retaining band or ring-15 is also employed .ugs,

in connection with theglobe or bulb 2, this 1 band or ring being slipped upon the end of the-globe-or bulb prior to its insertion Within v.the socket 1.. The band or ring 15 is split, as -qat 11.6, -to..'if'crm -a d7i 11fldel"W-liil(h .athe wire 11 upon eachside or 'the bulbisadapted to pass. After-the holder has been placed in engagement with the bulb or globe 2 and the socket 1 the cap 4 canbe easily and iiickly placedover the: end of the socket and ocked thereon, whereby the-bulb or globe-,2 cannot be surre titiously removed from the socket 1 The obe or bulb holder is preferably constructed of light and durable metal and of a non-fusible wire, which in no manner whatever will shield the light radiating from the bulb or globe 2 when the same is being used.

Such changes in the construction of my improved globe as are permissible by the appended claims may be resorted to without departing from the spirit andscope of the invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a lock for incandescent lamps, the combination with a lamp-socket and a lamp bulb or globe in said socket, of a split cap mounted on the socket, a wire passed around the globe or bulb lengthwise thereof and having its ends fastened to the cap, and a retaining-ring carried by said wire and surrounding the upper end of the bulb or globe, substantially as described.

2. In a lock for incandescent lamps, the

' combination with a lamp-socket, and a bulb "bait or gkme pieced in engagement the or globe carried thereby, of a split cap'fitted on the upper end of the socket, pierced lugs'l carried'by said cap, a lock e aging said pierced lugs, a wire carried by iiiecap and extending around the bulbior globe len th- I 5 Wise thereof, and a retainin -ring carrie by the wire and surrounding tie upper end of the bulb or globe.

In testimony whereof I affix my signature in'the presenceof two witnesses.
