Application na'rebmr a7. 1904. Serial in. 195,632.

To all whom it may concern:

Be it known that I, REUBEN B. BENJAMIN, a citizen of the United States, residing at Chicago, in the count of Cook and State of a certain new and useful Improvement in Electric-Lamp Sockets, of whichthe following is a full, clear, concise and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to electric-lamp sockets, and more particularly to improved means for wiring the same. .7 r

In an a plication for United iates letters Patent ed March 21, 1903, Serial bio. 148,861 ,1 have described a lamp-socketemhodying certain generic principles of construction, and I have inserted in said application generic claims thereon.

The present invention relates to a species of the generic invention described and claimed in sai application above mentioned, and it -is to be understood that the resent application is subsidiary to the pending application aforesaid.

The object of my invention is to provide a. lamp-socket having means associated therewith whereby the same may be readily and conveniently wired.

My invention is particularly a plicable to weatherproof sockets; but it wil be understood that the features of my invention are also applicable to other forms of sockets.

I have illustrated my invention in the aocompanying drawmgs, in which like characters indicate like parts throughout the several figures. I

Figure 1 is a side elevation of my improved socket, showin parts broken away to expose the interior. line 2 2 of Fig. 4. ig. '3 is a sectional view taken on the line 3 3 of Fig. 2. Fig 4 is a sectional view on the line 4 4 of Fig. 2. Fig. 5 is .an enlarged detail view showing the method of wirin Referring to larly by re erence characters, the base 1 is made of insulating material and is prefer ably housed in a one-piece metal casing 2; but as an suitable casing The casing 2 is proton. forms with a tapering rear end .1, which duit orsup a, as

nay be em loyed.

aded to receive a con the base 1 being retained wit the in any suitable manner; as by the formed in the base to shown, casing screws 4, a recess being formed in the bottom of the iormed in the base 1.

. 2 is a sectional ViBW on the. is to be rea g the drawings more parting reoeive'the same. Disposed within a recess in the base i is a lamp-receiving shell 5, held in position therein b bolts or screws 6, passing downward throng the base 1. A portion 0 the lamp-receiving shell 5 is out awav, as shown at 7 in Fig. 2, tectspiate 8 to pass 7 7 through the sense. Th s plate is preferably dis seed in a recess .3 ormed in the bottom 0 the base 1, and has a outwardly and ads ted to rest upon aeentral projection or wal l0, base 1, which wall or projection serves to msulate the center contact-plate S from the other lamp eontect-piate 11, also beingadisposed in a recess cite or screws 12 12,

portion thereof bent passing downwardly than cure the contactlates 8 an 11 in position on the front of the see, the usual binding posts or serews13 13 being carried b the contactplates 8 and 11 and accessible cm the front of the. socket; ,The particular formation of thecontact plates above described and the base 1 are not essential, and the'jorm and disposition of the lamp-con tacts may be varied without departing the spiritpi iyinvention. I prefer-ab 3 provide two; openings or ehanne s14 14 in the rear end of thebase 1 through which the leading-niw-ires 15 may be passe the walls of said openings r0 'ded with flaring walls to more readily guide the leading-m wires to the binding-posts; but this is not essential.

Proieeting into the openings or channels 14 aresmall fingers 16, preferably formed intosl with the contact-plates 8 and 11 and out slight toward the front of the socket to permit t 6 feedwires when inserted ir the rear of. the socket through the channels dily hooked over the fingers 16 and lodged so as to be clamped in position when the binding-screws 13 are tightened, as

o shewn'in Fig. 5.

In my $011316! application above referred to it is necessary to wrap. the leading-in wires about or inseit the some under the binding-screw in making aconnection, which is more or less difiicult. I desire to provide means whereby the socket ma be wired without the necessity of any mampulation of the who or any e 'in the form thereof to permit the center con-- h the base 1, se-- after the wire has'beeujnserted in the socket andI accomplish thfig'lgbending the end 0 the wire toiotm a hook b? removin a per,-

tion ofithe insulatinnfthere rom and orming a loop therein, s in ich' is inserted from the rear IIC I CL

of the socket and after being placed over the Iingcr Iii l he bindin yscrew 13 may be screwed down from tin iroritol' the soilu-t against the Wire, as above dcsi'riivad instead of the fingers and screw 'cnteniplati' as an CI uivalent any incans for wiring the lamp-soclict in which thcconilii ion or form of the wire is not i i Wiiirgi) n"; manipulation of the i *rtiicw rc is ins-"meal in the socket. i of my inx cntion above described, which 1 have worlnnl out conmiercial purposes, may he variiil a d that oth r mechanical means for wiring the; socket which do not require the wrappi 11;: of the fccd-wirc about the hindin -scrizrws or other nninipulation of the wire star the wire has been inserted in the socket may be adopted.

The method of wiring inyimproved socket is obvious. A portion of the insulation having been rci novc i from the leariling in wires, a loop or hook is formed therein and being insertcd from the rear of the socket is placed over the finger 16. The binding post or screw 13 may-hen be driven home from the front of the socket and a firm electrical connection between the leading-in wires and the con tact-plates secured Having ilesr fbed my invention. what I claim new, an o desire to secure by Letters Patent, is

1. In a iampsoclret, a lamp-receptacle and snare that the particular form suitable contacts therein, passage-ways extending through the rear of the socket and communicating with said receptacle for the entrance of the leading-in wires and a pair of binding-posts in. the bottom of said receptaclc consisting of screws accessible from the front of the socket, and coi'iperating fingers projecting into said passage-way over which fingers the lcadingdn wires are adapted to be looped and clamped by said screws.

2. In a lamp-socke,t, an insulating-base, having a lamp-receiving receptacle formed therein, a metallic inc/losing casing for said base having a threaded opening at the rear end for engagement with a conduit or support, suitable conacts llL said lamp-receptacle, a pair of passage-ways extending through the rear of said base and communicating with said receptacles, and a pair of binding-posts in the bottom of said receptacle consisting of screws accessible from the front of the socket, and overhanging fingers projecting over said passage-ways around which the leading-in wires are adaptedto be looped and clamped by said screws. v

In witness whereof I have hereunto subscribed my name in the presence of two Wit- DGSSQS.
