This invention pertains to inner controlled spotlights adapted to be mounted upon or through some portion of the superstructure of an automobile or other vehicle within convenient reach of and accessible to the driver of the vehicle although adaptable for other( uses and purposes.
One of the primary objects of the' invention is to provide a spotlight of the character `described so constructed that the lamp may be tilted up and down in a true vertical plane and at the same time swung to any'and all positions in a horizontal plane thereby eliminating the usual hunting for the correct or desired position of the light beam. y
Another object is to provide a spotlight construction of the character specified which will be compact and simple in construction and thereby reduce the amount of space usually found necessary for lights of this character. In this connection a pivot for the vertical movement of the lamp is within the lamp casing.
Another object is to provide a spotlight so constructedthat the lamp and casing will be held positively at its position or positions of adjustment and cannot swing or move under the influence of gravity or vibration from such adjusted position by accident. The spe cial arrangement of a self-locking worm'gear and an arrangement whereby the gears and parts are vkept in tight frictional engagement with one another materially aids in attaining this object.
A further important object of the invention is to provide a simple and effective elec#V trical connection within the bracket and operating mechanism of thespotlight.
VStill urtherobjects include the'` provision of a novel handle arrangement,a novel post clamp bracket adapted to preventthe elbow from turning, va novel'adjustable stop on the inside of the caradapted to be set or ad. justed to preventthe light beamfroin being directed beyond predetermined limits withlout placing strain upon the gears andoperating parts and a number of other unique features all Vor. which together with` the .advantages, uses and functions ofthe invention and the preferred form illustrated should bel or 1928..

Y Fig. 5 is a detail view taken along the line 5-5of Fig. l. Y i
A portion of the light which is adapted to be situated on the exterior of the car orother vehicle comprises an elbow bracket orV sleeve,
generally designated 2 composed of a horizontal or inner part 3 and a vertical or outer part 4. A cap covers an aperture on the` l outer side of the elbow and'isadapted to-be removed for access to the gearsand contacts for inspection orrepaiing Thevouter when desired and when in position may be secured against removal while the inner part 3 at its free end is likewise split as shown at 7 sothat it may be adjusted about and ses cured to a suitable'clamp member 8 arranged to be secured to the corner post or other structural portion of the vehicle superstructure as will be understood.
y The outer` part 4 of the elbow sleeve or housing is adapted to receive a sleeve-9 for rotation therein. This sleeve .whichhas a head 1l integral therewith at one end and a bevel gear 12 integral therewith at its other end is provided with a circumferential slot 1.3 within whicha key 14 is slidably posi-A tioned and held against displacement bya lock screw l5 which also serves to draw the sides of the split part ofthe portion 4 to! gether. The head ll is bored out transversely at right angles'to the axis of 'the sleeve asi shown at 16 for the reception of a cylindrical gear member 17 which at its ends is fric.-v
v'15 part is split as shown at 6 so that the lamp and its associated parts may be removed f end with a bevel gear24, the Worm gear 23- being adaptedto meshv with the gear teeth Of the gear membfrlv?. T he outer endpeition of the longitudinal bore of the headk 11 and sleeve 9 has itsl axisdisposed at an to VtheaXis of the sleeve and head and preferably theaxis of this portion lriesin a plane perpendicularv torand intersecting the axis of the'gear 17. v Thus an externally threaded 'I yring vplug when screwed intol the correspondingly threaded bore of' this portion is canted with respect to thel axis ofthe head and sleeve so that the inner surface thereof provides a slanting abutment for the circularly beveled end of the Worm gear 23 and f will cause the gear 23- aiid the sleeve 2 2 to be urged laterally toward the gear V17'1should there be any movement of the sleeve 22 and -gear 23 Vvertically upward.
This'tend-s to maintain the gears 17 and 23 tightly in'mesh Y with one another.
In order to permit slight movement of the gear 23and' sleeve 22 under the influence above described and under the influence of a small kidney-shaped spring 26v positioned in a circumferential recess in the inner sleeve 22 whichalso aids to keep the gears 23Y an i .Y 17 inl mesh the bore in the outer sleevev 9' is shaped from a true circle'27 atits llowerend to a substantiallyV elliptical shape 28 lat its top end' While for the purpose of preventing .the inner sleeve and outer sleevefrom moving any substantial distance relatively longitudi- L nally of'one another smallv lreys 2 9 and 31 may A be provided.
f As above mentioned the inner sleeve 22 is Y `.hollow and at its loiverend is countersunl; g. lo receive an insulated bushing 32 within which a spring pressed contact element 33 having a ballsocket in its l'oiverend is posi- 'U tionedV and secured primarily by 'a solderedl 4 connection with a conducting Wire 311 which no leads through the inner sleeve 22 and ring Y plug 25 to a V Contact 35 ina lamp socket 36.
The brackets 18 which are fri-rationally securedl to the gear17A are of course secured toV the opposite interior sid'es of the lampcasing 37' which is apertured at its lower .side as shown. at 38 to permit the passagey of the head 11.
The gear12 on theouter sleeve l9 is adapted lto mesh with andbe rotated by a hollow bevel gear @secured to a hollow sli-aft or sleeve 41: which, projects through tothe interior of the vehicle. The gear 24likeivise meshes with a,
hollow bevel gear 42, secured on the" end. of
a, hollovv.A shaft or sleeve43 Within the hollow sleeve or shaft a1 and also projecting through to the insideof the vehicle and in order to maintain the gears 39 and Ll2 in tight engage-V ment respectively with the gears 12 and 24 at all times and to compensate for Wear a spring lil is disposed between ring abutinents 45. one of which' in turn abuts against a collar or bushing 46 normally secured to but adjustable longitudinally of the bracket or .housing portion andthe other'of which in turn abi-its against a shoulder formed on the gear 39. Cooperative shoulders on the gears 39 and .1l-2;` permit the vspring lil to urge both gears longitudinally of this portion of the housing While a sleeveor-bushing 47 between the abut'- ment rings prevents the gears vandshafts from moving any substantial distance longitudinally inward, l
A conductor 48 passes through the hollor7 inner sleeve or shaft 43- and at its outer end,- that is, the end within the elloovv bracket,
electricallyconnected with a ball contact 49' normally seating Within lthe ball socket formed in the Contact "Ehi-s' conductor 4S and the ball i9 are preferablyfi-igidly se-V cured to the inner shaft43 by'insulating bushingsy 51 'and 52 to turn thereivitl'ia The conductor 43V at its vopposite "end is provided with a conductingcap or contact surface 5,3L
against which a spring brush secured to an insulating binding post 55: normally presses., A secondy binding post' 56' Visl also provided for connection'through a conducting Wire 57 which passes througl'il an opening in a boss l58 formed onone side of ahousing member 59, With a suitable source of electric energy and a circuit between' the binding` posts is established byr aV switch LVto* be described. Y f The housing member l59 is` adjustably secured to the outer shaftll by'means ofy a Y clamp screw 61 and on its interior isformed to relatively rotatably vreceive a bevel gear 62 Which is rigidly securedor keyed to theinner shaft Sand meshes with ai bevel rotatably carried 'na bosszGLl preferatbly' integrally formedWith the housing member 59.
The gear 63 is circumferentially; grooved as shown at 65 for the receptionl ofy a keyV 66, a securing pin 67 and a kidney spring 68all of Which serveto-'r'educe play between the, several partsrand tend to holdthem in ad` Gear i Justed position. Thej gearV 63is preferably formed integral With a shaft 69 which at its outer endV is rigidly secured toa handl'e71V so that it Amay be rotated, Y
The inner end' ofthe housing member 59 is closed by a cap 72I which supports a switch thev details( of which areV not illustratedY because they are,l Wellv known but designated 73,
While. a switch handle 74 projects rearwardly into a convenient and accessible positionyfor the hand of theoperaton At its opposite end the; housing 5K9 is provided With a limit ofl movementprojection or stop `75 adapted to engage alike projection 76 formedon a cas'- v through a split sleeve clamp 78 which also carries arms 79 for securing the light' to a stationary portion of the vehicle. Aclamp screw 81 serves to secure the housing sleeve 7 7 in its adjusted position so that the 'stop 76 may be set Wherever desired and also permits the sleeve clamp or bracket and its arms to be adjusted and set in any desired position longitudinally of the sleeve housing 7 7 to compensate tor different lthicknesses of super-j structure support to `and through which the spotlight may be secured.'y Y
It will now be apparent that upon rotation of the handle 71 about its axis the inner sleeves 43 and 2,2' will be rotated lto tilt the lamp about the-pivot screw 19 in a vertical plane or in a plane parallel to or containing the axis ot' the sleeve 422, while oscillatory or bodily movement of the handle 71 and hous-` ing member 59 about the axis of the sleeves il and 42 will rotate the outer sleeves 41 and 9`and the head 11 and the lamp about the axis of the sleeves 9 and 22. lt will also be appreciated that we have provided a novel spotlight construction in which the operating parts will stay in the positions to which they are adjusted and that compensation will automatically be made for wear. The parts are comparatively simple and cheap to manufacture and afford many unique advantages. It will further be appreciated that many changes may be made in the construction illustrated and described Without departing from the essence of the invention and for such reasons we do not desire to be limited except by the spirit of the invention and the scope of the appended claims.
