universally mounted dirigible lamp, having mechanism for operating the same, in-

eluding novel gear elements which facilitate smooth and eflicient manipulation of the spotlight.

Another object of the invention is to provide operating mechanism for the spotlight, wherein electric conductors are utilized which are carried by the movable parts of the operating mechanism and so arranged as to prevent any possibility of the same being broken or twisted, and which are so disposed as to permit ready assembling and disassembling of the spotlight when desired, 'ithout the necessity of fishing wires through the parts of the operating mechanism.

Still another object of the invention is to provide a spotlight of a character adapted to extend through the windshield structure of a closed type of automobile, and wherein supporting means for the spotlight are utilized which may be readily adapted to supporting posts of various sizes and contours, and wl ich includes a ball and socket ar-- rangement permitting ap lication of the spotlight structure at di erent angles to the supporting post, together with a bracket of bendable material which may be bent to form so as to be secured to the supporting post in any desired position.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following. In the drawings forming part of this specification, Figure 1 is a side elevational view of the spotlight, the front and rear portions of which, and the supporting post to which tne spotlight is connected, being shown in vertical longitudinal section, and the lamp head being partly broken away to expose the interior thereof. Figure 2 illustrates respectively a perspective view of an operating gear associated with an operating shaft of the spotlight and a perspective view of the cooperating gear associated with the lamp head of the spotlight. Figure 3 is a transverse vertical sectional view through the forward portion of the lamp, corresponding substantially to the line 3-3 of Figure 1. Figure 4 is a transverse vertical sectional view through the rear portion of the operating mechanism, corresponding substantially to the line 44 of Figure 1. Figure 5 isa horizontal sectional View through the rear end of the lamp, corresponding substantially to the line 55 of Figure 1.

Figure 6 is an'e-nlarged fragmentary, vertical sectional view of the spotlight, showing the supporting means therefor. Figure 7 is anenlarged fragmentary horizontal detailed sectional view through the lamp head gear and showing the same in mesh with the related gear of the driving shaft. Figure 8 is an enlarged fragmentary vertical sectional view through the lamp head gear and showing the same in engagement with the related ear upon the drivingshaftJ As shown in the drawings, the spotlight is adapted to be applied to the corner .post of the windshield structure of a closed, car, said corner post being indicated in the drawings by the reference character 6. In order to mount the spotlight it is necessary to pro vide an aperture extending transversely through the post 6 at any suitable angle desired, an aperture 7 being indicated in the drawings. To the outer face of the post 6, in proper position with reference to the aperture 7, is secured a supporting bracket 8. The bracket 8 is preferably elongated in form and has its outer marginal edges strengthened by means of a pressed corrugation 9, inwardly of which are provided a number of openings in the bracket to permit the passage of holding screws 10, which are utilized to secure the bracket to the post 6. Centrally of the bracket 8 is provided an outwardly extending truncated ball-shaped member 11, having a central opening 1:2. Co-operating with the bracket 8 is the lampcarrying member 13, which is in the form of a tubular member, having a flared portion 14, the inner surface of which is globular to co-operate with the ball-shaped portion 11 of the bracket, there being provided vithin the flared portion'an annular flange 15, which provides a shoulder to co-operate with a part presently referred to. The member 13 is provided with a hollow tubular extension 16, which extends rearwardly through the opening 7 in the post 6 a suitable distance, and forms with the lamp-carrying member 13 an outer shaft adapted to rotate about its longitudinal axis upon the ball-shaped member 11. A threaded annular portion 160 is formed upon the extension 16 adjacent the ball-shaped member 11, and threaded upon the portion 160 is a ballshaped part 161, which fits the inner surface of the ball-shaped member 11, the member 161 being provided with an annular groove 162 which may be filled with a felt washer,v

which bears upon the inner surface of the ball-shaped member 11. j The extension 16 is provided at the rear of the post 6 with a holding bracket 17, said bracket having bendable prongs 1818 adapted to be secured to the post 6 by means of screws 19. The bracket 17 is provided with a sleevelike portion 20, which is split to provide a pair of ears, indicated at 21, which fit about the extension 16 and are secured together by means of a bolt 22, which may be tightened or. loosened as desired, to thereby vary the frictional contact of the sleevelike portion upon extension 16. The sleevelike portion 20 is provided with an arcuate extension 23, adapted to co-operate with lugs 24 at opposite sides of the collar 25. The collar 25 is clamped to the extension 16 by means of a bolt 26, the lugs 24 being adapted to co-operate with the arcuate portion 23 to limit the turning movement of the extension 16, and further to hold the extension 16 against forward longitudinal movement.

The lamp-carrying member 13 and the extension 16 are rigidly secured together by a driving fit as indicated at 29, and the two form the outer shaft which is provided with a central bore 27, in which is rotatably mounted a shaft 28. The forward end of the shaft 28 is provided with a gear made up in the form of an annular enlargement 30, which fits in a counter-bored socket 31 of the lamp-carrying member 13, a coiled spring 32 being interposed between the member 30 and the shoulder 33, provided by the bottom of the socket 31. The annular member 30 is provided with an annular series of teeth along its forward edge, indicated 1 by the reference character 34. The teeth 34 are of peculiar formation, being defined by a series of cut-out portions 35, the opposite de fining walls 340 of which are straight and disposed parallel to each other, and parallel to radial lines projected from the longitudinal axis of the shaft 28. The bottom of each cut-out portion is curved, as indicated at 36. The teeth 34, so defined by the cut-out portions, have their opposite sides undercut, as best shown in Figures 2 and 3, and said teeth are of a character to co-operate with a gear connected to the lamp head, as hereinafter described. Disposed within the base portions of the teeth 34 at the end of the shaft 28 is a central annular portion 37, which projects beyond the forward edges of the teeth 34 to form a thrust bearing.

Co-operating with the gear 30 is a gear 38, which rotates about an axis disposed at right angles tothe axis of rotation of the shaft 28. The gear 38 comprises a journal portion 39, provided at its lower edge with an annular flange 40 against which the central projection 37 on the gear 30 bears, and outwardly of the flange 40 of the gear 38 is provided with gear teeth 41, adapted to mesh with the gear teeth 34 of the gear member 30. As best shown in Figures 2, 7 and 8, the teeth 41 of the gear 38 are of peculiar formation so as to co-operate with the teeth 34 in a peculiar and eflicient manner, whereby great ease and smoothness of operation are obtained. The teeth 41 are each formed as a segment of a ball at its engaging surface. The curved surfaces 410 are adapted to be presented for engagement with the flat walls 340 of the gear 30 during the horizontal approach and recession of said surfaces longitudinally with reference to the shaft 28, as best shown in Figure 7, while the curved surfaces 411 are simultaneously presented to the gear teeth 34 to take care of the movement of the teeth 34 in their vertical plane of movement, as shown in Figure 8. In other words, the

teeth

34 and 41 travel relatively to each other in two planes and the curved surfaces 410 of the teeth 41 provide a rolling engagement between the

teeth

34 and 41 in a horizontal plane, while the surfaces 411 provide a similar rolling engagement in a vertical plane, the

surfaces

410 and 411 merging to provide a ball effect so that the ball surfaces roll upon the fiat walls 340 in two directions, producing great smoothness of 1 operation and efficiency in action. For this way tight running gears are provided without lost motion between the teeth thereof, the flange 40 bearing upon the annular projecting portion 37 in such manner as to maintain a predetermined clearance for the teeth and eliminate bottoming of the teeth, which ordinarily results in the teeth bumping over each other during rotation of the gears. The journal portion 39 of the gear 38 is rotatably mounted in a nut 42 threaded into the chamber 43 of the lamp-carrying element 13, which nut is provided with an annular channel 44, in which is mounted a coiled spring 45 which bears downwardly upon an annular shoulder 46, formed upon the gear 38. The journal portion 39 of the gear 38 is provided with a reduced annular portion 47 over which fits a washer 48. The lamp head is provided with a portion 49 which rests upon the washer 48, and the reduced portion 47 of the gear projects through the portion 49 of the base of the lamp. The portion 37 is still further re duced and threaded for the reception of a nut 50 threaded thereon, between which and the adjacent surface of the portion 49 of the lamp is interposed a washer 51, the arrangement being such that the lamp head is maintained in position and rotates with the journal portion 39 of the gear 38.

The outer shaft provided by the extension 16 and lamp-carrying member 13, at its rear end, carries a handle support 52, which is in the form of a casting having split sleevelike member 53 at its forward end, which fits over the end of the extension 16 and is rigidly detachably clamped thereon by means of a bolt 54. The handle support 52 is provided with an annular flange 55, in which is rotatably mounted the journal portion 56 of a gear 57. The journal portion is provided with a flange 58, which bears against the flange of the support. The handle proper, indicated at 59 rests against the undersurface of the flange 58, and the handle 59 is provided with a' central hollow sleeve 60, extending therethrough, adapted for the reception of a screw bolt 61 which is threaded into the gear 57. The gear 57 is provided with an extension 62, having a reduced portion 63 extending through the wall 64 of the handle support, which reduced portion is internally threaded for the reception of a set screw 65, the head of which bears upon a flanged friction-generating element 66, the latter being provided with a sleeve portion which rests against the shoulder provided by the extension 62. By this arrangement too free rotation of the gear 57 is prevented. The handle support is provided with a socket 68, in which is mounted the journal portion 69 of a gear 70, which meshes with the gear 57, the gear 70 having a central polygonal opening adapted for the reception of the end 71 of the shaft 28, which is polygonal in section to fit the opening in the gear 7 0, whereby the gear 70 and shaft 28 rotate in unison.

The electrical connections include a conductor 72, extending from a suitable source of supply to a switch block 73 of any suitable character. The switch block 73 is preferably supported by a cup-shaped member 74, detachably connected to the rear end of the handle support 52 by means of set screws 75. The switch 73 is adapted to be operated by means of a lever 76, which projects through the rear wall of the cup-shaped I member 74. Connected to the switch block is a resilient conducting member 77, which extends forwardly past the extension 66 of the gear 57 and is coiled about the same, as indicated at 78, and provided with a reverse lly turned end portion 79, which resiliently bears upon the rear end of a conducting rod 80. The conducting rod is rigidly mounted in the shaft 28 so as to rotate therewith, and extends entirely through said shaft to a position where it projects from the forward end thereof, as indicated at 81, the portion81 being annular inform. Co-operating with the portion 81 of the conductor 80 is a conductor 82, carried by the journal portion 39 of the gear 38. Conductor portion 82 is provided with a plunger section 83, slidably. disposed within a flange member84 driven into the lower end of a thimble 85, fitting within a block of insulating material 86, disposed in the central chamber 87 of the journal portion 39 of the gear. The plunger section 83 of the conductor is provided with a flange 88, adapted to limit downward movement of the conductor 82, and interposed between the upper surface of the flange portion 88 andthe bottom of the thimble is a coiled spring 90. The thimble 85 is connected to a wire 91 which extends upwardly through the annular portion 47 of the gear 38 and the threaded portion thereof and the nut 50, to the base of the lamp bulb, indicated at 92, thereby conipleting one pole of the circuit, the remaining pole being suitably grounded upon the lamp structure, and the circuit completed to the battery of the car by means of the wire 93. In operation, when it is desired to swing the outer shaft, composed of the extension 16 and lamp-carrying member 13, about its axis so as to impart swinging movement to the lamp head, the handle 59, is grasped by the hand of the operator and oscillated to and fro, without rotation about its individual axis. The movement of the outer shaft is limited by reason of the stop lugs coming into engagement with the portion 23 upon the bracket 17. Too free rotation of the extension 16 is regulated by the clamping ears 21 on the sleeve-like portion of the bracket 17.

l/Vhen it is desired to rotate the lamp head about its vertical axis, the handle 59 is rotated about its individual axis, imparting rotation to the gear 57, the gear 70, the shaft 28, the gear 30, the gear 38, and thence through said gear to the lamp head. Of course, it will be appreciated that rotation, both about the horizontal and vertical axes, may be effected simultaneously, if desired, by one hand of the operator, through combined swinging movement of the outer shaft and rotation of the handle on its individual axis, which effects rotation of the shaft 28. The supply of electricity to the lamp is controlled through the switch lever 76, which may be manipulated through the fingers of the same hand of the operator which is utilized to impart the required movements to the lamp head. The electric circuit is effected by reason of the fact that the resilient conductor 77 continuously bears upon the rear end of the conductor 80, which in turn rotates with the shaft 28 and bears against the conductor 82 which, through the thimble 85 and wire 91, conduct the current to the base of the lamp bulb, the other pole of the circuit being grounded on the lamp struc-' ture.

The lamp-carrying member 13 and extension 16 may be disposed of any desired angle with reference to the post 6, by reason of the universal connection of the flared portion 14 of the lamp-carrying member with the ballshaped element 11, as will be understood, the bendable prongs 18 of the bracket 17 being bent to whatever position is necessary, whereby they may be secured in proper relation with respect to the opposite side of the post 6. In any position in which the outer shaft, comprising the lamp-carrying member 13 and extension 16, may be mounted, it is afforded free rotation upon the ball-shaped member 11.

The lamp, as thus provided, may be conveniently assembled and disassembled during application, or for purposes of repair, and assuming that it is desired to disassemble the lamp from its position as shown in Figure 1 it is only necessary to loosen the bolt 54, remove the handle support 52, and the collar 25, after which the forward portion of the lamp, including the lamp-carrying member and extension 16, may be moved forwardly and completely removed from the mounting, it being noted that the gear slips off of the polygonal end 71 of the shaft 28 during this movement. The reverse operation, of course, takesplace when the lamp is being applied to position. It is particularly pointed outthat the electrical connections are susceptible of disassembly with the parts above referred to, without the necessity for fishing wires through the shafts, or other awkward procedure. Access is provided to the switch through removal of the cap-shaped member 74, carrying with it the resilient conductor 77. Due to the provision of the particular type of gears provided between the lamp head and the forward end of the shaft 28, the gears are held in tight engagement so that no lost motion occurs, and the teeth thereof mesh in such manner that the same do not bump over each other. Particular attention is also called to the fact that the conductor rotates with the shaft 28, while the conductor 82 is carried by the journal for the lamp head in resilient contact therewith, whereby any amount of rotation of the lamp head, with respect to the lamp-carrying member 13, will have no effect in interfering with; the operation of the conducting means and does away with any possibility of kinking or breaking of wires, so common in othertypes of lamps.
