"PLURAL' LAMP-SOCKET- SPECIFICATION forming part of Beissued Letters Patent No. 12,286, dated November 22,1904. Origins-1N0. 759,983, dated Kay 17, 1904. Application for reissue filed August 26, I904.- Ssrial No. 222,185.

To all whom) it -mn, 1 concern: Be it known that I, REUBEN B. BENJAMIN, a citizen of the United States, residing atChicago. in the county of Cook and Stateof Illinois, have invented new and usefulImprovements in PluralLamp-Sockets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming part of. this speci- I fication.

I My invention plural lamp-sockets, one object being to provide a constructionin which the successive outer and inner contacts of the lamp-holding I5 devices are electrically. connected together and another Ob ect being to provide improved;

means for holding-the inner ends'of. the separate contact-plates together, and at the same time insulating them.

A further object is the provision of a socket of simple and eflicient construction.

To the accomplishment of these objects my invention consists of the parts and combinations of parts hereinafter described, and par- .ticularly pointed out in the appended claims.

' In the accompanyingdrawings, in which'the' same reference characters designate like parts throughout the several views, Figure 1 is a section, and Fig. 2 is a-face view, of one form embodying my improvements. Fig. 3 is a section on the line 3 3 of Fig. 2.. Figs. 4 and'5 are respectively face and sectional views of a "modified form. Fig. 6 is a section of still a difierent'form. Fig. 7 is 'a detail view ofa different methodof securing the inner ends ofthe separate'contact -plates, and Fig. 8 is a similar view of a modification.

In Figs. 1, 2, and 3, 2 designates an insulating-base, preferably of porcelain-and of the 4 form shown with the sloping sides, upo which base the separate contact-plates 3 of ring form are mounted, their inner ends being secured to the base by screws 4 and their outer ends by the screws'5, passing through the top ring of the base. The threaded metallic shells 6 of the lamp-holding devices are secured to the -r1ng plates 3 by soldering their outwardly-extendlng flanges thereto. Each of theplates .of -the base 2' intermediate its ends,,'whereby relates to improvements in screws to secure the socket in place.

. 13, preferably upon the thre ed shells 6.

vries a similar arrangement of separate connected in the circuit by 'a' strip 18, upon which setto receive the otherrwires.

: :3'e2icept the last plate of the series isprovided with a laterally-extending and preferably in- 5 ,tegral strip 7, which extends beneath the center of the succeeding plate '3 and forms the C811:-

ter contact for the lamp of that holding device. I r

The strip 7 is bent to engage the side or wall the end of the-strip forms a spring-contact for the center terminal of the lamp. The first-lampholding device of the series is provided with r a center contact formed from a strip 8, secured to the base'by screw 9. 'A binding-screw ,10 serves to secure the end of one circuitewire to Y the strip, anda similar screw 11 permits the other to be secured to the last contact-plate of the series.- The circuit-conductors themselves are brought in from the rear through thecentral aperture in the base. The lamps are therefore in series in the electric circuit. Suitable apertures in the base permit the passage of A preferably metallic cover 12, having holesforthe lamp -holdingdevices,is provided for thesocket and'is held in placeby the insulating-bushings rcelain,'whichar e threaded In Figs.4 and 5 the insulating-base 14 car'- tact-plates 3, provided. with center contacts, formed by-stri'ps 15, secured .by screws or bolts 16 to 'a ledge 'formed upon the base. Other strips,- 17 are secured to the inner ends of the contact-plates 3 and extend laterally, so as to bear upon the inner ends of the inner contacts, as more-clearly shown in Fig. 4.- The first inner contact. of the se'riesis con- 8 S the binding-screw 19 islocated-to-receive one wire of, the light-circuit, a similar screw 20 being carried by the last contact-plate of the Fig. 6 shows a two-light cluster, in which the base 21 carries the center contact 22 of the left-hand lamp-holding device, upon which abinding-screw 23 is located to receive one wire of the electric circuit. .-The two plates 3 are secured to the base at their inner ends and together at theirouter ends by the insulatingplate 24,'astrip extending across to a point opposite the center of the other lamp-holding device. The said stripmay be bent to engage 1 the bolt 30, passing through the base 31, the

'said outer ends are preferably bent, as at 32,

of a succeeding device, substantially as dethe raised wall of the base to support the strip 25. A suitable binding-screw 26 serves to secure the other wire of the circuit thereto, whereby the lamps are connected. in series when placed in-the circuit.

Suitable apertures, such as 27, may be provided in the flat portion of the base, through which to pass suitable securingscrews to fasten the socket to the wall or other support, while other apertures are provided to'pass the circuit-Wires through. The cover 27 is substantially the same as in Fig. 1 and is held in place by the insulating-bushings 13, the edge of the cover being held in place by'the raised rib upon the base.

'Fig. 7 shows how the outer ends of the contact-plate 3 may be held together by the outer insulating-washer 28, the inner insulatingblock 29, upon which the said ends. rest,and

block 29, and the washer 28, thus clamping all 'togeth'erwhen the bolt is tightened. The

into a depression or depressions in the end of the block 29. Fig. 8 shows substantially the same arrangement, except that the block 33 does not rest upon the base 31 and the bolt 34 is correspondingly shortened.

While I have described the specific construction of the various forms, it is evident that various changes may be made therein. and I therefore do not wish to be so limited: but
