To all "Loh-ma it may concer/ri:

Be it known that I, ALFRED WILLIAis'il Britain, residing at the presen't'time in the" borough of Manhattan of the Vcity of New York, in the county and State of New York, have invented certain neWand useful Iniprovemeiits in Illuminating Devices, of which the following is a specification, reference being had to the aecompanyingdraw ings, forming apart hereof.

This invention relates to improvements in mountings and ttiiigs for'lainps 'which are tubular inform and in particular for lamps known as double-ended 'incandescent lamps; rovide a n'ovel form of mounting or iitting in which a sprinis employed forthe pur ose of making electrical contact with the el ectrodes at each end of the lamp and also flor the purpose of positioning the lamp definitely between any two siicli mountings er i'ittings In mounting these lamps it is )refei'able to employ a tubular member or soc et in which the endsof the lamp are received'and supported, such ends generally being capped and often alive, as it is through these ends that the electrodes pass. The tubular members -eoiei' up and protect the ends and forni a' very convenient means for shielding the live parts such as the electrodes, contacts etc. will be obvious, however, that with the tubu larnembers nearer together than a lamps len th (which arrangement ,is necessary if botli ends -of the lamp are to be received in the adjacent tubular members), some means must befadopted for inserting and fasteningV the lamps between 'said tubular members. If'the latter are 'formed with outside openings, or any other makeshift for permitting.

the insertionof the lamps, and are rigidly mounted u on their frame, as is preferably the case, t en a lampto be placed in posia tion must 'have one end inserted far enough into one tubular member until the 'other end therein far enough 'to permit the 'other end vof the lamp to be inserted into the' adjacent, s'ocket ;then the two sprines at the ends of the lamp ad1ust e lamp ItV ' between them infsiich ai'position-.that both of 1 its ends will be duly capped or covered by the .tilib'ularlilnemberlsla ielultjwliich would not .aways ap en esst e.spr1ngs enough. to -ilisur'e a. deiinite position for the 60- Were stiff lamps- Lamps of the character .referred to are often arran ed in line so asto give a line of light, 2and t e tubular members are accord- 1 V ingly arranged each to receive the opposing 6 5 caps or ends of ad'acent lamps# In'further accordance with t 's invention, the sprin s in each tubular member are .preferably ma e, of a single or integral piece embodying two spring contacts or terminals. In the drawings, one embodiment of the invention is illustrated and lshows a. short length of a reflector frame having tivo of the tubular members secured i thereto .and one` lamp in osition between said members.

In sai( drawings-Figure 1 is a longitudinal section ,View ofthe device, and, Fig. 2 is a transverse section thereof on the plane indi* cated by the line 2*-2 in Fig. `1.

' The single plate i has integral with it two S0 `contact pieces or terminals i. and "iand is firmly attaehd 4to the reflector or other frame and insulated thereon'in any suitable i.

manner as, for instance, by means of a block of insulatingv material y', adapted to fit the S5 inside of the frame a and through `which passes a bushing'lv of insulating material to. the exterior of ithe'rame a. Through theI bushing 'l vand the late i a screw or bolt m 'may be passed an 4nfia'y be rovided iyith al 90.

nut -and Washer nl screjwe on'thetgmside thereof in= order=to hold this plate and its spring contact pieces firmly in position.

Electrical connection is made between the lampsvl and 'conducting wires, (which. are pref-r '95 erably locate'd respi'ectivelyin4 beads b formed on each side of the 'frame and running along longitudinally therewith), by connecting the -alternategplates-'il with the same wire, so thatwhen a lamp isinj osition between the spring 100 clip 'i' at one en' andthe spring clipi i? at passed through its filament, 4theelectrodes of the lamp being: in lelectrical 'contact'withthe clips 'i' and-iiz respetivel 'Each lamp sup- 105l port is therefore -a doub esupport and will I'connect the` opposing nds of the Atwo adjacent lamps to one' pole of the electric circuit.

Over the supporting plates and their tersired. This shield forms with .the frame a,l

minals i and 'i3 a shield 'w may be' placed which shield can be made removable if dewhat may be referred to as a tubular mem.- ber into which the opposing ends of adjacent lamps are received. From the drawing, it Will be seen that in order to cover up the caps and other live parts of the lamps and supports, 4it is necessary that each ofthe lamps `shall be deiinitely positioned so that the cap shall Aat all times remain covered by the tubular members or shieldw and hence the spring pieces i andi2 must b`e relatively stiii' so as to maintain the lamps always in a rpredetermined position.

The manner of inserting and withdrawing the lamp .Willbe understood from the fore- I going 'and the drawings, las will also its mannerof support within the tubular members -at each end thereof.

lMany departures may be made Dfrom theaonstruction shown and described Without cvoiding" the 4spirit .of` the invention. For

instance, in the drawings,the caps @t2 upon the ends of the lamp are made to do'service as electrodes, but, as will be obvious,v the lattery may be otherwise embodied in the" improved structure.- Moreover, the form of the tubular members at the ends of the the latter tov the tubular membersl lamp may be changed in many ways as alsov may the lamp supports and the relationfg course, too, it is not` necessary that the framea be a reflector so far as the present invention 1s concerned.

4I claim `as my invention:

1. In an illuminating device, the combination with a double-ended incandescent lamp having at each end a ca embodying van electrode, of a frame, a tu ular member at each end of the lamp in which members the respective caps on the lamps are received,V

land a spring terminal within each tubular member "adapted'to make electrical 'Contact with the corresponding electrode of the lamp, the spring terminalsy bei relatively stiff to position the lamp definite y and thus maintam its lends at -all times within the tubular members. 'i

2. In an illuminating device, the combmation with aplurality' of double-ended incandescent lamps arranged end to end, each such lamp having at each of its ends a cap embodying an electrode," of a frame, tu ular vmembers on the frame and in each ofv-which the opposingr caps of the two adjacent lamps, are received, and spring contact members within each tubular member adapted to make electrical contact with the corresponding electrodes of the two adjacent lamps, the said spring contactv members being relatively vstiff so as to position the lamps deiinitely between the tubular members and maintain each lamp with its ends at all` times vwithin the ad'iacent tubular members.

3. In an 'illuminating device, the com. vbination .with a plurality of double-ended' incandescent lamps arranged end vto end, each such lamp having, at each end a cap embodying an electrode, of a frame,tu bular members on the frame, and a single spring within each tubular member embodying two l contact members one for each of the two lamps; entering said 'tubular member, each oi said springs .embodying electrically one electrode and being adapted to make electrical contact with the corresponding electrodes in said lamps.
