The reel Q9 ma of the construction shown in my rior nited States Letters latcnt Nnlnber 1.175,498. dated March 1l, 1916, and illue4 tnlcd in Figs. 2 and ot' the drawingsA Lait. roel embraces n rcwinding Spring (foinrising a number of sidewirw. disposed coil pringe` iltl' that nre colunfctvd iu Series to n caring :ZW and n Shaft lll)2 in a manner to act ai; a Single spring. Thie cinistrnction oi' reel is ,ulvantagwne innsnuicli :is it is "our pact and has a wide range to adapt it to long lmnp vorde. .11nd ite.` resistance to with drnwal of the cord is Substantially uniform throughout its range of action. lt also per mits the casing 31 to be made within the proper limits of dimensions,

One end, the shorter end 35, of said L- shaped fitting 3l provided with nn ix-- teriorly tapered portion 36 which lits in an intcriorly tapered bushing B8, which is alf taehed in any suitable manner to the caring opposite the neck 32. Said portion :lo ot' the tilting is provided just outside of its taper 3G with nn nnnnlar fmtwardly facing shoulder lill which located in a plan@ onV tcrior to tht` rnd lace of the bushing 35. lli designates a nut which is internally screw thrended to engage exterior screw threads on the bushing 38 and is provided with n radial annular tlnnge 41 to engage over the annular shoulder 39. ,lVhen said not is screwed home the flange 41 acts on the shoulder 39 to foi-ee the tapered portions 36 and 37 into friction-al Contact to prevent normal angular movement of one part on the other. If desired a spring washer 42 may be interY posed between said nnt and easing to afford a yielding friction joint and to also aid in locking the nut in place. This conte/ct of' the tapers, however, is snob as to permit thc fitting 3l and the lamp carried thereby to be singularly adjusted about the anni of thin hnshi g 38 when moderate force il; applied, and the taper bearings are of snfxh character (as one being made of brass and' the other of steel) as to withstand Snrn relative frictional movements without 1iuhstnntial Wear.

The other or upright arm l-i ol" the fitting lll extends through a line-hing ll that le litted in a suitable opening ol'I the lower side of the Slim-t ioctnl lump liod'i.F or easing and may he attached theretoin any suitable inanner, as by rivets extending through a flange Llo of said bushing and the elnet metal lamp body around said opening. Said arin Lt3 of the littingje tapered to engage an interior taper ot the bushing Lll., und the extreme end of aid arm Ll-l in screw threaded within the lamp body to receive zt nut ll which :serviley to tonfo the tapered portionsy ol the bushing AIl and nl'in klil into frirtional vontact. Preferably a yielding washer 42 and a whether 50 are interposed between said nutland the flat upper end face of the bushing 44 to in'odnce a yielding frictional tapered joint, and to also lock the nut in place.

in order to avoid twisting ol the conductor nord` which would ooenr by turning the lmnp about the axis of the bushing 44 an indefinito number of times in one direction, l havo provided n stop whioh limits the turning niownieut o? the lmnp body5 while permitting it to torn enl'ietantially througln ont lin range ol en entire circle Tllie may he aet'fomplishod by flattening the screw threaded portion of the arm 43 of the fitting 34 and Htting thereovor the washertlhaving an opening to interloekingly tit on the {lattened portion of Seid fitting so as to turn therewith. The said washer is provided with a short radial arm or stud 5l, which is adapted to engage n. stop lng 52 on the bush-- ing 44 or its Hanger From the foregoing description it Will be apparent that the v construction is so a1'- ranged as to normally function as :i uni! verselly adjustable spot lamp; the tapered joints between the two arms of the fitting 34 and the bushings 38 and 4l, respectively, giving a {naeticnlly universal adjustment to the lamp. When it in desired to extend the lamp away from its posit-,ion of snpport on the vehicle in order to nee it as a trouble lmnp or for other purposes, the nut 4() is removed from thc bushing Btl so as to permit the lamp and the fitting 84; to be tative, separableg jon, at :mid tails-up device nature in th@ presen@ of two wzwmes at. msmg, :md provided ai? :is outer end with :1 Chicago, lmols. this 4th day of November, 10 lamp camg bearing ejonshuaed with manna 1916.
