LAMP-SHIFTER.

Application ii'led May a0, 1911. Serial No. 628,373.

l To all whom la' may concern:

Be it lmowii lthat I, [vosY li. Silooitnx, a'e citizen of the United States. re.-;iding :it laulton, in the bounty of \Vestniorcl.|nd and State of Penlis) 'i'aiiia, have invented :i new and useful Lamp-Shifter, of which the fol lowing is a spor imitation.

It is 'the obj cl. of the present invention to provide a di vif-e adapted to connect. the movable axle epd of a vehicle, operatively, with a vehielffearried, rotatable lamp, in suoli a inannet that when the vehicle axle is shifted, to permit the vehicle to round a curve, the lamp will be rotated, to projectl the light in the direction iii which the ve hielo is turning.

A further object of the invention is to provide novel means for connecting the lamp operatively with axle-carried mechan ism for rotating the lamp, in such a manner .that the vertical movement of the vehicle body upon the springs, will be ineffective to injure the lamp.

With the foregoing and other-objects in View which will appear as the description proceeds, the invention resides in the coinbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without de parting from the spirit of the invention.

In the drawings,-Figure 1 shows in front elevation, a vehicle equipped with the device of my invention, parts being broken away; Fig. 2 is a section upon the line 2'-2 of Fig. 1; Fig. 3 is a section upon the line 3--3 of Fig. 2; Fig. 4 is a section upon the liiie 4 4 ofFig. 1 ;Fig. 5 is a section upon the line 55 of Fig. 1; Fig. 6 is an elevation of -tlie drive shaft; and Fig. 7 is a bottoni plan of the lamp-carrying i'nion.

Tn the drawings, 'the body o a vehicle 4is shown, and denoted generally by `the numeral 1, the numeral 2 4denoting the front axle, the

numerals

3 and 4 denoting vthe movable axle ends, and the numeral 5 denoting the wheels which are carried by the

axle ends

3 and 4.

lRemovably united, as shown at 6 with the ino-.able axle end L3, is a horizontally disposed segment 7, having upon its u per face, and at its inner end, a rack 8, a apted to mesh inte a vertical pinion 9, secured to a in bearings 1l, forming a part of the bracket 3 the bracket 12 being supported upon the axle 2 hy means of channel standards 14, or in any other desired inaniier. At its inner end. the shaft 10 is equipped with a vertical, bevi-lod pinion 15, meshing into a horizontal, beveled pinion 1G, located Within an open head 17, foi'iiied upon the inner end of the bracket l2, the pinion lf3 heilig secured to a vertical shaft 13, comprising a. plurality of sections 1f), located above the head 17 and tongue and grooved together as at 20, for pivotal union. l'he shaft includes, as its uppermost member, a stem 21, of polygonal cross section, as shown at 22, the stem 2l being adapted to register, for vertical sliding movement, but against rotation, in a head 23, formed at the lower end of a shaft 24, journaled for rotation in bearinvs 25, conneotedby means of a base plate 2G, or in any ther desired manner, with the veliicle bo y` l.

Secured to the upper end of the vertical shaft 24, is a horizontally disposed, beveled pinion 27, meshing into a vertically dishorizontally disposed, forwardly extended auxiliary shaft 29, journaled for rotation in bearings 30,.carried by the vehicle body 1. At its forward end, the shaft 29 is equi ped with a vertically positioned pinion 31, adir ted to mesh into teeth 32, formed upon t e lower face of a horizontally disposed pinopen frame 34, carried by the body 1`0 the vehicle.4 In the upper face of the pinion'33, there are studs, or other suitableA means, indicated conventionally at 35, which'means are adapted to'secure to the pinion 33,' `for rotation therewith, one ofthe lamps 36 with which the vehicle is equipped,

The pinion 33 is toothed at its'periphery, as shown at 37, so as to li'iesli into a rack 38, formed in one edge of a horizontally disposed bar 39, mounted for longitudinal 'sliding movement in bearings 40, carried by' the body 1 of' the vehicle. At its opposite end, and adjacent the. side of the vehicle which is remote from the operating mechanism, the bar or operating member 39 is e uipped with another rack 41, adapted to mes into a horizontally disposed pinion 42, journaled for the bracket 39, the upper face of the pinion 42 carrying suitable means 44, adapted to horizontal shaft 10, journoled for rotation engage with the other vehicle lamp 45, so

ion 33, journaled for rotation within an posed, beveled pinion' 28, carried upon a rotation in an open bracket 43, similar to `meeting the shaft with the 45 and the pinion 42 may steeringr mechanism of any sort (not shown).

When the axle end is thus shifted, the segi'nent 7 will be tilted likewise, the rack 8 of the segment 7 meshing into the pinion 9, and causing a-rotation of the shaft 10, the pinion l5 et which, meshing into the pinion i6. will cause a rotation of the shaft 1S.

Z The shaft 1S and its accessory parts, will canse a rotation of ythe slneft 2l, the pinion 27 of which, meshingr into the pinion 28. will cause a rotation of the shaft 29. pinion 31 which is upon the shaft 29, meshlng into the teeth 22 in the lower face of the pinion 83, will rotate the pinion 33, and with the pinion 33, will rotate the lamp 36. When the pinion 36 is thus rotated, its peripheral teeth 37, meshing into the rack 38, will cause a longitudinal slidin movement of the bar 39, 'the rack 41 oigwhich, meshing into the pinion 42, will cause a rotation of the pinion 42, and with the inion 42 will rotate the other vehicle lamp 5.

Owing to the fact that the stem 21 of the driving shaft 18 is mounted for vertical sliding movement in the head 23 of the shaft 24, the body 1 of the vehicle will be free to reciprocatie, vertically, upon' its supporting frame, without disarranging the operating mechanism whereby the lamps are turned about. Moreover, owing to the fact that the drive shaft 18 includes a plurality of pivotellyconnected sections 19, a. lateral relative movement between the body 1 and the axle 2 may takeplace, without disarranging the operatingA mechanism.
