To 0.5K whom it ,may concern: Be it known that LNELsoN WEEKS, a citizen of the United States, residing in Richmend Hi1 in the county of Queens, State of New York, have invented Improvements in Electric-Lam l Fixtures, of which thefsilos'ri isa specications y inventionwrelstes tociuster or plcral' electric-lamp -fixturesthiit is, fixtures for retaining a nurrrber of electric iarnp's in position on one base',rthe receptacles or sockets for the lamps beingeleotrically connected to gether either inrnultiple or in series, or both, as the case may require. r

The main object of my invention is to produce such a. fixture thatch the terminals, contacts, and connections shall be easily ascessible to facilitate installation, ins action and repair. This object I accomplis in the preferred embodiment ofmy invention which have developed for commercial use by securing the sookets'or-Irccegtaoies for the lamps at upon the removel of the cover the receptacles, which tske up a great part of the interior ofthe fixture, wi I removed 1 with the cover and leave exposed on the facecf the base alithe connec tions. i In accord ce with my invention, broadly considered, lisrovide a' suitabie basic or so porting part, hich may be of'any suitable and 006 eretin with this basic or en part pmvi e a. metallic casing d tachab connected therewith and having a plum ity of lanip-openings.

Likewise I referahiy mount the center contacts *dn'eot y upon the basic or supporting "art ofthe structure. While, as above states, I preferably mount the bindingposts and the-center contacts upon the basic or supportin part of the structure, this is not essential, an these pairtsmay be otherwise suitably mounted Within the casin .The invention will be more perlectly unto the accompany drawings; in which 7 V gore i is 3 face View of the base with the cover removed.

These 'contectssiare secured to the base: by;

screws" as assingitthrongh fornmci'in t e The'contacts may: be connected; npgto snnpler have showntheicon-t in the face'ofthe inane J, is placed a Witch efore the several contacts 8 are finally se suitableholes? cured, so that when the securin -screws for these contacts are tightened up t e contacts w ll be electrically connected together by the wire.

One of the contact-plates s is made longer than the others and tapped and threaded to receive a binding-screw s", to which one lineterminal is to be secured. Adjacent to this bindin -screw I refer to form a hole H in the ho y of the ase for the introduction of the line conductor. 3

Through the center of the base I pass a screw S, astened in place b Y a nut n and projecting from thebasesome 'stance to act as a securing-post for the lamp-carrying cover 0.

The annular portion A of the base is preferably divided into a number of compartments a, separated by insulating portions p, preferably molded with the base and of a wedge or-pyramidal shape having a gradual slant from the periphery of the base to a point about in the same plane as the projection J, but se arated from it by an intervening space 1, tlirough which connecting-wires 4 can be asscd, as hereinafter described. At the bac of each compartment a, standin out a little from the wall of the projection J,

place a forked contact Y, fastened to the base y a screw 3 in such osition (see Fig. 3) that the ends 'y of the for s are ap roximately on a line with 'the bent-over end .9 of the contact-piece 8. These forked contacts Y are electrically connected together by a wire 4.

and clamped in position behind the partitions under the bent portions y of the forke' contacts, Figs. '1 and 2, upon the tightenin of the securing-screws 3. To one of the forkedcontacts Y is electrically connected a piece 7, Fig, l,with a binding-screw 6, to which the end of the line conductor is connected a hole 5 in the baseserving for the introduction of this conductor.

It will be seen that when the cover is off all connections and terminal wires are exposed and unobstructed, thereby permitting not on] great ease of installation, inspection, an repair but also securing great ease of assemblage in the manufacture.

The. cover C is bowl-shaped with a central opening 8 for the passage of the threaded post S of the base, on which it is secured by a thumb-screw 9, Fig. 2. To this bowl-shaped cover I secure as many metal rings 10 as there are to be lamps in the cluster. These rings may be secured in place by flanging over their outer edges against the ed es 0 the corresponding holes in the body of t e cover.

Within each ring 10 I secure an insulating.

bushing 11, which is intemall threaded to receive the o n-ended thre ed socket or receptacle 12 or the Edison type of lamp. I wish it to be understood however, thatldo not confine myself to sockets of this description, as it is obvious that any other form of lamp-holding contact to hold the lamps radiatingyfpreferably, in positions oblique tn the axis 0 the cluster can be readily adapted to the clusters of my invention.

Upon placing the cover in place, Fig. 2, the inwardly-turned flange 13 of the socket 12 makes contact with each arm of the contact Y on opposite sides of the socket, while the contact s is opposite the open inner end of the socket and in proper position to make contact with the central end terminal of a lamp when inserted into the socket. The forks y p of the contact Y are preferably given a s i ht spring action, which is readil obtained y securing them at the turne over end y) on] so as to stand out a all ht distance om t e projecting planeJ w en the cover C is oil.

' In Figs. 5 and 6. I have shown a modification arran ed for series wiring and haveshown but three amps in the cluster. The cover and sockets are shown similar to those-of the receding fi ures. The forked contact YP,

0wever,is's a ed somcwhatdiflerently from the fork Y an is secured to the base by a 'screw 14. It is adapted to make contact'on the outside ofthe socket-shell 15 instead of at the flange, as hereinbefore described. 1 The projecting central planis replaced in this modification by a truncated cone J ,"form'ed with a deep cavity 16 opening to the-back of the base. Externally the cone has a Him 17 part way up its slanting sides for the reception of connecting-wires 18 and 19 and the terminals 20 by which the wires are secured in place. These terminals 20 are fastenet. in place by screws 21 each passing through a slot 22, extending om the'inside of the cavity 16 to the outside. The slot is preferably formed by molding the porcelain with long channels 23 perpendicular to the base and enetrating from the inside-to the outside of the porcelain, leaving a slot, as shown, substantially at right angles to the wall for the reception of the screw 21. Fig. 5 shows sixof these channels so placed that the base can-be used for either a threeor a four lamp cluster, as may be desired. For each channel 23 it is necessary in this con- 'struction to provide an adjacent opening 24 to receive 'the screw 14, which secures the forked contact Y. In this modification I have shown the lamps connected up in series. Wires 26 27in a groove adjacent'to the contacts (Y serve to complete connection between the line-terminal 30 and the various forked contacts and lamps, while the wire 18 from the contact 20 is connected, to a line-terminal31, a notch 32 being formed in "the wall of pore'win, ifdesired, at this place. Theline-wires are brou htin throu hopenings 33 in 'the base, whi e 34 34 are oles for the screws to secure the'base to the ceilingor wall. A raised will 35 may be formd on'the base to hold 'the cover in position- )ut'it-is not essential. It isshown cut away at 36 '36 for the line-wires should it bedesired to bring them in to the cluster from the side instea of from the back of the base.
