KEY-SOCKET ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed February 25, 1913. Serial No. 750,581. 4

7 '0 all whom it may concern:

Be it known that I, Eowilv N. Mirror-.12, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of .Illinois, have invented certain new and useful Improvements in Key-Socket Attachments, of which the following is a specification.

My invention relates to attachments for operating lamp sockt keys and the object of this improvement is to provide a simple and effective device of the character men tioned which may be easily applied to a socket key of an electric lamp, or the like, and adapted to operate said socket key by simply pulling the pendent chains or cords carried thereby.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a view, in perspective, of a device embodying my invention, Fig. 2 is a central vertical section of the same, and Fig. 3 is atransverse section of the same.

The preferred form of construction as illustrated in the accompanying drawing comprises a hollow body portion 4 being cut out and struck up from a piece of sheet metal in substantially the shape shown, its open side 5 being preferably at the bottom. The body 4 is preferably of a resilient material and left open at 5 to provide an adjustable clamping means to fit different sized socket keys. The body 4 incloses an opening 6 into which the key of a lamp socket, not shown, is inserted. Perforations 7 are provided in the body 4 to furnish a means by which the device may be attached to the socket key by a rivet, cotter pin or the like, not shown.

The body portion 4 is provided with laterally extending arms 8'. which are cut out and bent substantially in the shape shown. The metal from which the body 4 and arms 8 are formed is flexible enough to permit the arms 8 to be bent at different angles to accommodate different strokes which are necessary for different socket keys. longer stroke is required the arms 8 are bent in substantially the positions shown in Fig.

\Vhere a 3, at S and when a shorter stroke is desired, they may be bent to the solid line shown in the same figure, or in any other similar positions as required. The metal from which the parts are made is rigid enough to prevent their bending under use. To each of the arms 8 are provided pendent chains 9.

One of said pendent chains is provided with a ring 10 and said ring is slidably mounted on the other of said chains 9 to maintain the lower portions of said pendentchains close together. A ball 11, or its equivalent is perforated and the lower end of one of chains 9 secured therein by means of an enlarged link 12, or its equivalent, resting against a shoulder 13 in said ball. The other of said chains 9 is slidably mounted through the perforation of said ball 11 and provided at its lower end with a similar ball 14. The end of the chain 9 engaging ball let is secured by means of an enlarged link, or its equivalent 15 resting in said perforation against a recess 16 therein, substantially as shown. On the rear end of the body elare formed projections 17' which aroprovided to prevent chains 9 from passing by the rear end of the body 4 when the device is attached to a lamp socket set at an angle. Should the chains 9 pass to the opposite side of body 4 the chains would become entangled and not produce their required functions. I

\Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without depart ing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

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

1. A device of the kind described comprising a lamp socket key engaging clip having laterally extending arms; a chain carried bv each of said arms; a perforated member carried on the lower end of one of said chains and the other of said chains slidahly mounted in said perforated member.

2. A device of the kind described comprising a piece of sheet metal cut out and struck up forming a lamp soc rot key engaging clip mama-ma igned my zcationin the presencq of 111g Witnesse EDWIN N. MINCER.
