SPECIFICATION forming part of Letters Patent o. 601,108, dated March 22, 1898.'

l; Application filed Gotcha-1,1897. Serial No. 653,735. (No model.)

To all whom, t may concern.: B e it known that I, NELSON WEEKS, of New `York city, in the county and State of New York, have invented a new and Improved Cluster-Fixture for Lamps, of whichI the following is a full, clear, and exact description.

This invention relates to fixtures for in- A candeseent electric lamps, the said ixtures being of the kind in which a number of lamps are arranged as a cluster. In fixtures for this purpose as ordinarily made it is necessary in placing the fixture to splice the lampLwires to the house-wires and to run the lamp-wires through atubewhichl is necessarily of con'- siderable length, because the cup employed to cover the splice must be moved down the pipe in order to enable a person to ymake the splice.

Ono object et my improvement is to provide affixture thatlmay be applied directly to a ceiling, wall, or other support and in whichthe usual short extended ends of the housewiring may be attached .directly to the lamp-contacts.

Another object is to provide a fixture that will present a compact and-neat appearance and'which will be comparatively inexpensiveA to manufacture.

I'will describe a cluster-fixture for lamps vand then` point out-the novel features in the appended claims.'

' Reference is to be had tothe accompanying drawin gs, forming a part of this specification, in which similar characters of vreference indicate corresponding parts in all the views.

Figure 1 is -a sectionon the linc 1 1 of liig.

2 oi a ixture embodying my invention. Fig.

2 is a partly sectional plan view of the base' of the fixture on the li'ne 2 2 in Fig. l. Fig. 3 is a section similar to Fig. l, but showinga modification; and Fig. 4. is a section showing another modification.

l Referring first to the example of my improvemcnt shown in Figs. l and. y 2, 1 designates a base of lctile material-such, for instance, as porcelain-designed to be attached to a ceiling or other support in any desired manner. l have here shown 'it as provided with openings for lthe passage of screws 2;

Removably attached to the base l is a cap 23 also of iictile material. This .cap may. be scoured to the base by means of av screw 4,

depending from the base, and a thumb-nut 5, engaging with said screw at the outer side of the cap. If desired, a shade or reflector 5 may have its inner edge secured between the base and the cap, asindicated in Fig. 1. The

base 1 carries a number'of contact-points,

and the cap 3 is provided with a pluralityof openings through which the base portions of lamps may be inserted and engaged with the contacts.

This particular fixture is designed for use with lamps of the 'l`l1omsonI-Iouston type. The base l has a-contracted dependingcentral portion 6 and a still further contracted depending portion 7. Extended inward in the base is a. contact-plate 8 for each lamp,

through the cap 3, is a contact-plate 16', haying a projection 16", designed to engage with the ring-terminal 1T of the lamp. lhe several contact-plates lli are electrically connected by means o fa ring 1S, seated in'a channel or groove, formed in the inner surface of thecap. ,"When Athe cap 3 sin place, tho'contact-finger 14 will engage upon oneof these contact plates 16, as indicated lin Fig. l..

The center contacts ofthe lamps, which in this class of lamp are in the ferm of interiorlythreaded thimblcs, will engage with screw-plugs lf), connected with screws 20, the several screws 20 being electrical] y connected by-means of a ri'ng.21,'surrounding a portion of the base. One of the screws 20 is in con lnectionl with a contact-plate 22, vwhich has a fusible-plug connection 23 with a plate 24, with which the house or main 1ine-wre'25 connects.` In the operation of this example of my improvement the lanrpswill be screwed onto the screw-plugs 19 and the terminal 17 will be placed in ei'xgagement with the part 1U, and of course when lthe circuit is closed by any desired means the current will flow through the lamps.

In'the nzodilication shown 4in Fig. 2i I. eulploy a 'base and cap similar to the ones first 'loo the base] is a eoiitactfringe 2c, adapted to engage with thircenter contact of the lamps, a'nd also' in'euuteil on this hase is a contactring 27, designed ier engagement with the outer contact et' the lainp. 'llie ring 26 has a screw connection 2S with a plate 29, which connects with the house or line wire through a. safety-fuse S30. The ring 27 connects through a screw 31 with a wire 32, havngits opposite end connected to a screw 33, to the lower end of which. a safctyfuse 34 is connected, the other end of said safety-fuse being connected with a house or line wire in the saine manner.

In Fig. 4 l have shown the device as arranged in connection with a bracket or siinilar support that niay be extended from a wall or from a strect-pi'ist and. in which a cut-out is provided. The fixture shown in Fig. 1.1. is similar to that shown in'Fig. l. It is, however, located within-a shade or reflector 35, supported on a tubular bracket 36, through which the lineaiires extend. 'lhe line-wircs which extend through the bracket 36 are ecirnected with the switch 37, et' ordinary construction, and arranged within the shade or reflector i, and of course the lainp-teiiiiiiials are connected with this switch or cut-out. The stern 258 of the switch-or cut-out extends down through the hase 1 and also through the cap 3 and may serve as a ineans for holding the parts together. In Fig. 4, however, instead of arranging; the contact-plate 16 as indicated in Fig. l l have attached it directly to tlic screw lb', as indicated at 39, and of course the several parte will be electrically connected.

A fixture embodying inyinventien, itis ohlvioiis, may he easily attached to a ceiling,

wall, or other support and the safety or fusible plugs may be readily reached, when (lesii-ed, for renewing,` thein.

individuel socket for each laiup, cach generally inounted'on an arin. This is not only objectionable by reason of the diillculty in wiring, but there is a constant vibration, cspecially when the lamps are used in traveling vehicles. I provide, practically, a connected series of sockets, or', more properly, a, multiple socket in which there can be no vibration'.

Having thus described my invention, 1 claim as new and desire to secure by Letters Iatent f l. An incandescent-lamp fixture, comprising a base having a contracted central portion anda still further contracted central portion, contact-supports extended through each of the contracted portions, and a cap having a plurality of openings for the insertion of lampbases to engage with the contacts, substantially as specified.

2. An incandescent-lamp fixture, coniprising c. hase, two sets of electric contacts se cured thereto, a cap on the base and having a plurality of openings to receive lam p-bases, contact-plates on tho walls of the openings, each having projections to engage theringterminals of lamps, and a ring electrically.

connecting the several plates, substantially as specified.

3. An incai'idcscent-lamp fixture, comprising a hase, a series of electrically-connected screw-plugs carried by the base, connections between said screw-plugs and the leading-in wires, a cap on the hase and having a plurality of openings te receive lamp-bases, coni tact-plates on the walls of the openings and lia-vine,r projections lo engage the ring-termi-l nals of.' the lamps, the said projections engaging with certain of the contact-s on the base, and means for electrically connecting said contact-plates, substantially as specified.

NELSON WEEKS.
