HERBERT F. nonmsorvINoNNEs, iNnIANA A ADJUSTABLE LIGHT vApplication led July 9,

This invention relates'to an adjustable light and more particularly to a light'adapted for use ina j arage when inspecting or repairing automoiles. Y 5 One object of the invention is to provide a light including a standard and a light carrying rod so connected with the standard that it maybe adjusted vertically and circumferentially upon the standard and also` Another object of the invention is to Vproy vide an adjustable light so constructed that it may be used to illuminate the engine hood or the rod extended beneath the automobile and the transmission or other elements beneath the chassis.

Another object of the invention is to provide a device of this character which is very simple in construction and strongand durable and capable of withstandingV rough usage without being damaged. l

The invention is illustrated in the accompanying drawing, wherein Figure l is a perspective view of the improved light,

Fig. 2 is an enlarged sectional view illustrating the manner in which'the lamp carry- 'ing rod is adjustably connected with the standard, j A

Fig. 3 is a view showing a portion of the standard in elevation and the light carrying rod and its securing clamp in section,

Fig. 4: is a bottom plan view of the standard illustrating the manner` in whichl its base is formed, and

Fig. 5 is aview showing the lower portion of the standard partially in side elevation and partially in section. v

light may be a solid bar or consist of a pipe of the desired length. The lower end of the standard is threaded for engagement in a neck 2 rising from a disk 3 forming part of the base ofthe standard. A shank 4t which is The standard l of the improved adjustable j 1930. serial 1510.466561.

externally threaded extends downwardly from the base or disk 3 directly beneathy the standard and this shank `carries a clamping l j disk :5 zand. securing nut 6. VVThe nut is threaded upon the 'shank and whenl tightened 55 Y' forces the disk y5 upwardly so that strips 7 will be firmly clamped between the disk 5 and l the disk 8. From an inspectiony of Figuresk 4l and 5, it will be seen that the strips 7 exi tend across the lower, face of the disk'or base4 60 3 and are arranged in pairs disposed at right angles to each other. The strips` of each pairy are disposed at opposite sides of the shank 4 s Y and the Iunder face ofthe disk or base is recessed to form seats 4v8 tofreceive the strips 65 Aand lugs 9 which bear against outer side edges of the strips. Arcuate notcheslOare formed in the inner edges ofthe strips to receive portions of the shank and, therefore, when the strips are'set .in placewith their outer side 70 'edges bearing against the lugs 9 and the shank engaged in theirrecesses 10 they will be firmly' held against longitudinal ortransverse movement andwhen the disk 5 is applied to. the shank` and the nut 6 tightened 75 Y the strips will be rinlybound lbetween the'V disks 3 and 5g The end. portions of the strips lare bent downwardly toform legs 11 which arepof such length that the ends of all the strips rest upon the groundl or floor and cause 80 the standard ,to be well supported in a vertical4 osition. 'n l A f e lightcarrying rod l2 is o-f'a tubular l format-ion in orderv that power Wires 13 may be passed through it for engagement with"v 85 contacts ofl a 'socket 14 mountedv atrthe end of aside arm l''formed bybending one end of the rod transversely. Since the socket is'carried by an arm extending vtransversely from thev rod, the bulb4v 16 engagedin 'the 90 socket will project transversely from the rod andwmay be-adjusted circumferentially of .f the rod by grasping theV handle 17 at lthe other end of the rod and turning'the rod.

A main or primary clamp 18 and an auX- 95,-V

iliary or secondary clamp 19 are employed to adjustably connect therod 12 with'the standard 1. The mainfclamp consists Vof'a strip of resilient metal Vbent intermediate its j length to form'jaws20 between Vwhich the ',100 i standard is to .be gripped andthe Jfree ends a rigid secondary clamphaving an opening Y of these jaws are bent toward each other, as shown at 21. in Figure 2, to form terminal lips which engage about the standard.` A bolt 22 extendsthrough the auxiliary clamp and jawsof the main clamp with'its'head 23 Y l bearing against the .outer face of the auxiliary clamp and the 'threaded'.endof this bolt 'Y Ycarries a nut 24 having a handle 25 by means of which the nut may be easily rotated in `order to draw the auxiliary clamp andjaws of the'main clamp into tight bindingengagement' with the standard and lamp carrying rod. The auxiliary clamp consistsof a. strip of strong metal having vone endbent to form a iiange26` to bear against one jaw of the main. clamp and its other end bent Vto form a shorter ange 27 to engage about the rod 12 without contacting with )the main clamp.

this arrangement the auxiliary clamp `may beldrawn into tightbinding engagementwith therein to register with the openings 1n the jaws of the primary clamp and provided with spaced inwardly extending flanges of differ` ent lengths, one of which-bears against the other of. said rod units, a'single Vclamping bolt vextending:through Vthe openings in the primary and secondary clamps Yand' bearing against both rod units, said bolt being provided at one end with an enlarged head bear-V ing againstlthe-outer7face of the secondary Y clamp and having its.'k other end threaded, and

a clamping nut'engaging the threaded end i of the bolt for clamping one of said rod units ldirectly againsttheadjacent face of the yprimary clamp and the other rodunitjbetween Vthe Vterminalv lipsof said 'primaryjclamp ,i

The rod may extend horizontally, as indicated by dotted linesv in `Figure 1, in orderto extend beneath the auto-- mobile'or if it isedesired 'to have thel light illuminate the engine within the hood, the rod mayv extend at an upward incline, asI

shown in full Ylines in Figure 1, or ata down? y ward incline or any angle between the two which will dispose the light in the best position. Since the rod may be rotated, the bulb -may beadjusted circumferentially ofthe rod claim.:
