ELECTRIC-SOCKET STRUCTURE.

appnmm ma April 2s, 1920. serial no. avana.

vTo all whom it may concern.' n

Be 1t known that I, MAX. Hlcnsxovrrz. a citizen of the United States, residing at Chicago, in the' county of Cook and vState of in the case of so-called candle-sockets; and

as to another feature thereof, to electric sockets in general whether, or not, adapted to be used as parts of socket-structures of the character above stated.

One of my objects is toprovide a novel, .simple and inexpensive construction of electric-socket of the character above stated. Another object is to provide a novel, simple and inexpensive construction of socket for usein general and to which current-conducting wires for supplying current to the socket, may be economically and readily at' tached.

Referring to the accompanying drawings Figure 1- is a view in side elevation of an electric-socket constructed in accordance with my invention and adapted to form a portion of an electric candle-socket structure. Figure 2 is a similar view taken at a right angle thereof. Figure 3 lis asection taken at the line 3 on Fig. 1 and viewed in the direction ofthe arrows. Figure 4 is a perspective view of one ofthe current-conducting elements forming parts of the socket. Figure 5 is an enlarged section taken at the line 5--5 on Fig. 1 and viewed in the direction of the arrow. Figure 6 is a similar View taken at the line 6-6 on Fig. 2 and viewed in the direction of the arrow. Figure 7 is a broken section taken. at the line 7 on Fig 6 and viewed in the direction of the arrow.

Figure 8 is a view like Fig. 5, of another Ito 7 inclusive, the socket is formed of a shell 8 which is made preferably of insulating material, such, for (-xample, as paper board or fiber board, or any other desirable material, provided in the form of a tube, shown as open at its opposite ends and into one end of whlch the screw-shell'of the socket, represented at 9 and provided to receivev the screw-plug of an incandescent electric lamp, 00 and form one of the contacts of the socket,

is shown to extend, the shell 9 preferably extending slightly short of the end of the shell 8. The shell 9 is provided at its inner end-with a disk 10 of insulating material 65 carrying a center-contact 11 shown as formed of a plate 12 bent to present a contact-making. portion 13, the plate 12 being held to the disk 10, as by a metal evelet 14 extending through these parts. electrically connected therewith, as by soldering, one end ofa metal current-conducting element 15 of strip form, which extends along the iinside of the shell 8 and is equipped at its opposite end with abinding- -screw 16. A similar current-conducting element represented at 17, connects at its inner, reduced, end 18,'w1th the center-contact 11, as by solderlng i`t in the opening in the eyelet 14, this element extending'along the in- 90 side of the shell 8 and being provided at its outer end with a binding-screw 19. In ac; cordance with the illustrated embodiment of my invention, the shell 8 is slit as indicated at-20, at opposite sides thereof circumferen- 35 tially, and the material bet-Ween these slits and the lowerend of the shell inwardly buckled, as represented at 21, the lower,

ybinding-screw-equipped, ends of the

elements

15 and 17 extending into the spaces 90 nevertheless rendered readily accessible for the attachment thereto of electric-currentconducting wires leading from any suitable source of electric-current supply. The parts described are preferably assembled to the positions shown and described by attaching the

elements

15 and 17 to the screw part of the shell 9 and the center-contact 11, respectively, and these parts so assembled, assembled Awith the shell 8 to cause them to be surrounded by the latter. With the part-s 105 of the structure thus assembled, cement, represented at 22, and of any suitable character non-conductive of electric current, as for example the cement used in the wiring of electric chandeliers is poured into the end 11 The shell 9 has 70 of the shell 8 opposite that into which the screw-shell 9 extends, to fill this end of the shell 8, as shown, thereby firmly cementing parts described, in assembled would be supported in use las by screwing.-

it u on the threaded nipple usually provided in e ectric fixtures of the electric candle type. The frame 28 is referably made of metal and the upper en s of the arms thereof are formed with tongues 30 formed by slitting the metal of these arms. The upper ends ,of the arms referred to extend upwardly into the interior of the shell 8 along the side walls of the latter, these portions of the arms being preferably curved as shown in Fig.`

7, and the tongues 30 are bent outwardly, thence upwardly and at their upper extremities, inwardly, to extend into openings 31 in the shell 8, the material of this shell between the openings 31 and the lower edge y thereof being preferably closely` embraced by these tongues as shown.

It will be understood that in formin the socket shown the yoke-member 28 wo d be assembled with the shell 8, as stated, before the cement 22 is introduced into the shell, thereby also cementing the upper ends of the arms of the oke 28 in position, and firmly anchoring them in place, the shaping of the arms at their upper ends as stated, enhancing the anchoring e'ect.

The feature of connecting the frame 28 with the socket structure, as described, causes the structure to be ver rigid and possess a high degree of durabi ity at relatively low cost.

It will be understood that in so far as the yoke feature 28 of the structure is concerned, 1t may be employed in sockets intended for use otherwise than as candle-sockets, in which case the yoke 28 which wouldprobably be somewhat shorter, would form the support for the socket whether the socket extends in the upright position shown or is inverted, orV extends at an angle to the vertical.

Figure 8 is illustrative of another of the various forms in which the invention may be provided, the structure shown being of a'form more nearly resembling the ordinary form of socket in that it is vformed with a metal enclosing casing. In this construction, the internal lparts are shown as of the same construction as those shown in Fi 5 and the same numerals are used to esignate the several parts. The metal casin referred to is represented at 32, it being ormed of two telescoping sections 33 and 34, -the section 33 carrying the internal parts referred to and the section 34, which may be threaded as indicated at 35 for attachment to a. support, forming a cap1portion. end of .the section 33 is of enlarged diameter as shown at 36 and in the assembling of the said internal parts therewith, 4the cement 22 not only cements the various internal parts in position, but also, by extending between the shell 8 and the section 33, as shown, rigidlycements the casing 33 to the shell 8.

It may be here stated that by constructing a socket member as above described, it may be made very economically and possesses a high degree of durability and strength, the invention thereby providin a socket vconstruction which may be use in many situations where much` more expensive constructions of sockets are now required to beguseda While I have illustrated and described certain constructions embodying my invention, I do not wish to be understood as intending to limit it thereto as the same ma be variousl modified and. altered Without ,de arting fiomthe spirit' of the invention. at I claim as new and desire to secure by Letters Patent isg' 1.
