'Be' itjknown that I, EnNnsr-M. OLsoN, a

h citizen"ofthe United Statesyresiding at Chicago, in the county of Cook and State 5 of Illinois, have invented a new and useful Improvement in I Control= Mechanism for Lamps, of which the'following is a specifiv I 1 tation-of thewsleeve 231,:and';pinion-2; will cation;-'-i--- I M a This inventionr'elates to improvements in cont-rolyme'chanismfor lamps, andis espe-' cially"adapted for usein connection with lamps, such-ashead-lights, mounted on automobiles, boats,'*aeroplanes, and other moving things. For the purposeof explaining the featurespfmy inventiom -I have' he're shown it as "applied to ahead-light mounted and thence backwardly throu h theiradiator 1 to a position within=reach o the ,{driver of:

at the front end of an "automobile. The feature's' and advantages 'of the invention will appeai-"from the following'specificati'on.

features of my invention,"shown in the accompanying drawings, Figure 1 is a viewin side elevation of the front endof an automobile having 'mounted thereon a lamp con- Mounted onithe radiator, in any suitable I 'manner, such as by'the' bracket 11, is a'housing 12 which issubstantially inthe shape of an inverted frustrated cone, somewhat flattened at the'backside 'where it lies adjacentthe front surface of the radiator. The upper end of the casing 12 carries a circu lar turn-table 13' having diametrically-arranged upwardly projecting posts 14: which carry pivotally supported between their upper ends the lamp or head-light 16. Rotation of the turn-table is limited to substantially 360 by means of the pin 19 adapted to engage with the stop 21.

Projecting upwardly through the center of the turn-table 13 is a sleeve 23 carrying the pinion 2 1 at its upper end. Rotation of the turn-table 13 with respect to the sleeve 23 is permitted. The lower end of the sleeve 23 projects into a stationary bridge member 25 which is held in position within the casing 12 by means of the screws 27 at its end. Mounted on the sleeve 23 by means of the setscrew 28 is a bevel-gear 29 lying between the In' that form of device embodying ther H wheel 11 by which the same mayi'be rotate 'thesleeve 39 will cause rotation oftheturm I .mi filed October-20, 1921.

the automobile. ,The inner-end Qfithe tuber-,7 5 39 1S -pr0v1ded .withfasuitable .qpperatin gear wheel e2'is sufiiciently thin--to.-permita certain amount of "longitudinal movement: of the sleeve 39. It is normally held in the rearmost position by means rofsthe spiral; spring 415 .5 It is shown inthis -position in Figure 4. of the drawings. "When -in' this position the teethof the pinion 44:mesh with the teeth 50 of: the circular gear 51,-,mounted on the under surface ofth'e turn-'tab le V 13.

By means of this construction, rotation of table 13 and consequent turning of theila mp 16 in a horizontal plane. Such turning of the lamp in a horizontal plane will also operate to tilt the same for the following reasons: The bevel-gear 29 is mounted on the sleeve 23 sufiiciently low so that there will be some pressure of this bevel gear on the cork washer 30, thus yieldin ly holding the sleeve 23 against rotation. Because of this construction, when the turn-table 13 rotates, the sleeve 23 will remain stationary. This will cause the segment 32 to roll around on the stationary pinion 2 1, thus tilting the lamp. The parts are so arranged that when the tube 39 is rotated by means of the hand wheel or knob 41 to turn the lamp 16 to the right, this turning will cause the lamp to Gil. i

be inclined downwardly. The value of this construction is obvious at a glance. When the vehicle is going straight ahead, the lamp is set to point substantially horizontal. When approaching another vehicle, the car turns to the right. When this is done, the wheel 41 is operated toturn the lamp to the right and this turning also serves to tilt the lampso that it will pointslightly downwardly, thus removing the glare from the driver of the approaching vehicle and also serving to better illuminate the ground m the right and close to the front of the vehicle. After the vehicles have passed. when the straight road is-again taken, and the lamp turned to. the front again. it is automatically elevated-to the requisite height for straight driving.

Tilting of the lamp 16 may also be accomplished, as desired,- without turning the same in a horizontal plane. This is done by pushing the tube 39 forwarduntil the teeth of the bevel gear 43 engage with the teeth of the bevel-gear 29. This forward movement of the tube 39 serves to disengage theteeth ofthe gear 44 from the teeth ot' the gear 51. When the bevel gears 43 and 29 are engaged, rotation of the operating wheel 41 will serve to rotate-the sleeve and pinion 24 to raise or elevate the lamp 16, as desired. The spring 45 serves to slide the tube 39 backward when the pressure is released, in order to again engage the teeth of the gear 44 with the teeth 50 ot' the circular gear 51.

Means are provided for turning the lamp off or on as follows: Mounted within the tube 39 and adaptedto slide therein is a rod carrying at its inner end a knob 61. The rod 60 carries at its outer end a knife switch 63 through which the circuit leadingto the lamp 16 is led. Pulling or inward movement of the rod 60 serves to close the switch and outward movement to open the same.

The casing 12 is supported at the bottom by a vertically arranged tapered member suitably mounted in any manner at the forwardend of the automobile. The wires 1.
