Applicationfiled August 15, 1921. Serial No. 492,275.
To all whom it may concern: v
Be it known that I, CAMERON A. VVHIT- sn'rr, a citizen of the United States, residing at Chicago, in the county of Cook and State 6 of Illinois, have invented a certain new and useful Improvement in Spotliimps,-of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
' The present invention relates to spot lamps for automobiles, motor boats and the like. More specifically the inventionis concerned with that typeof spot lamp which, in the automobile adaptation, is operable from a control mechanism located withinthe drivers compartment. The pre-eminent advantage of this constructionresides'in the ability to operate the spot lamp from within the car in any type of car and under any condition. Spot lamps having this interior control feature are particularly adaptable to use on limousines and other closed cars,.and, in fact, are the only types of'spot lamps which can be practically mounted on a closed type of car. Similarly, in the case of the open body car, this control feature permits convenient operation of the spot lamp when the side curtains of the car are down,
without the objectionable necessity of unfastening the side curtains, and exposing the hand or arm to the weather.
The fundamental object of the present invention is to simplify and facilitate the operation of such types of spot lamps, by providing an improved and simplified form of control mechanism which can be operated with the utmost facility.- I
A secondary object of the invention is to provide an improved form of'lock ordetent for locking the lamp in any adjusted position. This improved 'form of .lock is so devised that its operation does not hinder or incumber the adjustment of the lamp.
Further objects will appear in the following description taken in connection with the accompanying drawings, in which:
Figure 1 is an elevational view of one form of improved spot lamp as mounted on a closed type of car; g
Figure 2 is an enlarged fragmentary longitudinal sectional view through the same;

Figure 16 is a fragmentary sectional view through the ball and socket joint of another modified construction.
Referring first to the embodiment illustrated in. Figures 1 to 6 inclusive, it will.
be noticed that the spot lamp proper, which is designated 4, has a universal mounting in a housing 5. This housing is supported on the body of the automobile in any suitable manner; in the embodiment shown this being accomplished by a supporting sleeve 6, which is mounted on or ad acent the windshield of the car. In Figure 1, the device is illustrated as being mounted on a limousine or closed body type of car, and in this adaptation the sleeve 6 is formed with an integral lateral angle bracket 7, which is screwed or otherwise rigidly fastened to the corner rail 8 of the'ear. The .operating'shaft I in my co-pending application, Serial No.
381,370, filed May 14, 1920. The control means for adjusting the lamp 4 consists of a single control knob 11, which/is situated in convenient reach of the driver.
The universal adjusting motion of the lamp is provided for by a forward and backtilting motion of the lamp, about a hori-' zontal axis, together with a rotational motion of the lamp about its vertical or inclined axis, as indicated by the various dotted line positions shown in Figure 1. This universal mounting isafforded by a ball and socket mounting of the lamp comprising a ball 12 confined in a spherical socket 13 in the top of the housing 5. The ball 12 is suitably secured to the bottom of the lamp handle 11.
4 by a' stem 14 and mounting plate 15'. For convenience and chea-pness of manufacture and assembly I preferably construct the housing 5 of two parts 16 and 17, which can join on a vertical axial plane extending through the center of the ball 12. Thus, one-half of the spherical socket 13 is formed in each casing side, whereby the casing may be readily assembled over the ball 12 for interlocking the same in the socket 13 without the necessity of additional screw-threaded socket glands, etc. The left-hand half 16 is illustrated as being formed integral. with the mounting sleeve 6, the other removable half 17 being, fastened to the meeting face 18 of the other portion by a plurality of screws 19. Both casing sections are provided with co-operating recesses 21 extending downwardly from the socket 13, which recesses embrace and guide a pin 22 which is slidably or reciprocably mounted in the ball 12. The pin 22 is provided with a longitudinal slot 23 into which projects a spline or key 24 extending inward y from the bore. 25 in the ball 12. The lower end of the pin 22 carries a driven bevel gear 26 which is in constant mesh with a driving bevel gear 27 mounted on the end of operating shaft 28 which extends back to the controlknob or Through the medium of the driven bevel gear 26 the pin 22 is adaptedto be rocked back and forth to incline the lamp up or down, or is adapted to be rotated when in its vertical position or any of its inclined positions, for rotating the lamp from right to left; To this end I have provided a novel construction of ball and socket mounting between the bevel gear "26 and the pin 22 which enables the gear to rotate the pin,- irrespective of the angle between the two; The ball 29 on the lower of the gear 26 and the collar 32 are formed with the co-operating halves of the spherical socket 31, these two members being assembled over the ball 29 by fastening the collar 32 to the face of the gear 26 by screws 33. Both the bevel gear and the collar are provided with diametrically opposite grooves 34, which are adapted to register to form vertical grooves for the reception of the diametrically opposite pins 35, projecting from the ball 29. By virtue of this construction it will be seen that the bevel gear 26 and pin 22 are capable of wide angular deviation without interrupting or interfering with the driving connection from the gear to the pin, whereby the gear is enabled to rotate the pin 22 when the pin is in any-of its inclined positions. The two gears 26 and 27 are firmly held in their right-angled relation for proper mesh of the teeth by a construction of yoke consisting of separable yoke sections 37-37. The collar 32 is formed with a flange, 38, and embracing the groove defined by the above mentioned flange are the horizontal semi-circular extensions of the yoke sections 37. The vertical extensions of the yoke sections 37 are formed with semi-circular portions to embrace the reduced portion 28' on the end of the shaft 28. A nut 39 screws over the reduced end 41 of the shaft and rotatablyconfines the yoke section 37 against the face of the driving bevel gear 27. This gear is threaded or pinned on the shaft 28. The ends of. the yoke sections are formed with lugs 42 for the reception of clamping screws 43 and the angles of the yoke sections are similarly joined by a screw 44. As an alternative construction, the yoke may be constructed in a single piece having ring portions at its ends for assembly under the collar 32 and nut 39. In addition to retaining gears 26 and 27 in right angle relation, it will be apparent that this yoke transmits the to and fro rectilinear or reciprocat ing motion of the operating handle and shaft 28 to the gear 26, for the pur ose of rocking the pin 22 and thereby the amp 4 about the ball and socket joint 12-13.
The yoke is assisted in retaining the driven bevel gear 26 in horizontal positionby inwardly extending shoulders 46 (Figure 5) against which the-top of the bevel gear 26 bears in its rectilinear motion. The opposing recesses 21 in the two casing halves,
the yoke 37-487. In this form the gear 26 is formed-with an upper annular. fiange 47 which is adapted to engage and be supported in longitudinal grooves48 defined by longitudinal ribs 49 projecting inwardly from each of the casing sections. In this form, the yoke 37 only functions to transmit the rectilinear motion of the shaft 28 to the gear 26. As illustrative of an alternative construction, the pin '22 can be 'formed integral with or fixed to the ball togetherthey form a housing or sleeve, but
the term sleeve as generally used in the claims will refer to part 6 or to parts 6 and 52.
As shown in Figure 1, the stem or sleeve 52. is preferably supported by threading over the reduced end 53 which projects from the supporting sleeve 6 through an aperture 54 in the windshield pane 9. The sides of the pane 9 and the aperture therein are provided with cushioning surfaces 5'5 of felt, rubber or the like which are compressed against the glass by the co-operating flanges 56 and 57, to avoid vibration between the lamp mounting and the Windshield pane and to avoid fracturing" of the glass around-the.
aperture 54.
Referring again to Figure 2, it will be observed that the control knob 11, which is preferably constructed of rubber, fibre. vulcanite, or the like, is provided with a sleeve 58 which extends inwardly over the end of the stem.52. The sleeve 58 is formed with flange 59 which is secured to the body of the knob or wheel 11 by screws 61 which also extend through a disc 62 mounted in front of the wheel or knob 11. The disc 62 is formed with a central hub 63 which isrigidly fastened to the end of the operating shaft 28 by a pin or screw 64. This end of the operating shaft 28 is provided with arelatively longdiametrical slot or recess 65 cut entirely through the shaft, there being a co-extensive slot 66 in the hub 63 to register with one side of the slot 65. Mounted in the slot 65 on a transverse pin 67 is a detent lever 68 whichis designed to lock the lamp 4 in any of its adjusted .positions by locking the shaft 28 against either Ion itudinal or rotary motion.- 69' pf this lever is adapted to engage in any one of a plurality of locking holes 70 in the end of the stem 52. These locking holes '1 he operating the azimuth and vertical.
The nose are preferably formed in a separate sleeve 7 1, which is rigidly secured in a counter bore in the end of the stem 52 to snugly engage over the end of the shaft 28. The nose 69 of the detent lever is adapted to be projected out through one side of the slot 65 to engage in one of the locking-holes by a leaf spring 72 which is pinned to the lever at 73 and has its resilient end bearing against the inner part of-the hub 63. vAs shown in Figure 4, one part of the operating 'knob 11 is notched out over a considerable portion of its periphery as indicated at 74,
- for the reception of a matching segment 75,
which is adapted to release the detent lever -68. The end of the lever 68 is flared outwardly in the form of a segmental plate 76 fastened to the back of the operating segment 75 by screws 77. The segmental plate 76 extends through the slot 66 in hub 63 and through the opening78 cut out in the flange 59. Y,
\Vhen the detent or locking lever 68 is engaging in the locking holes 70, it will be noted that the control knob 11 is rigidly locked against longitudinal motion as well as against rotational motion, so that the lamp 4 is firmly held in fixed position. To
release the lock, the lock releasing segment 75 is merely squeezed into the body of the knob 11, this motion being thenatural result following subconsciously from the simple act of grasping the operating knob 11. In making an adjustment of the lamp the knob 11 is then shifted either backwards or for- .Wards or is rotated, depending upon the direction in which the light-beam-is to be swung. The longitudinal shifting motion of the control knob tilts the axis of the lamp, forwardly or backwardly in a plane parallel to or coincident'with the plane of the operating shaft 28. The rotary motion of the control knob revolves the lamp about any of the selected axes in this plane. By the proper combining of the shifting and rotary motions of the control knob, it will be apparent that the lamp may be made to assume various intermediate anglesbetween The adjusting motion readily becomes instinctive, it being noted that simultaneous adjustment in both planes can be performed by a twisting or cork-screw motion of the control knob. The multiplicity of locking holes'70 enable the lamp to be locked in practically any adjusted position.
In -Figure 7. I have illustrated a more simplified construction wherein the upper bevel gear 26 is carried d rectly on the ball 12' about wh ch the lamp 4 is arranged to swin In this form, the housin 5 can be made considerably smaller, owing to-the fact that it is not necessary to provide 'room for horizontal'motion of the gear 26'.) The housing is preferably of generally spherical upper section 82 of the upper bevel gear has spherical socket 05.
rotatable mounting. The upper and lower halves 82 and 26 of the upper bevel gear are formed with cooperating; semi-spherical sockets, which unite in a spherical socket 83 assembling over the ball 12. The two sections 82 and 26 are preferably secured to gether by screws, similarly to the screws 33 of the previous embodiment (Fig. 3), and both upper and lower sections are provided with diametrically opposite grooves 31 which are adapted to register to form vertical grooves'fe-r the reception of the diametrically opposite p ns 35" projecting from the ball 12'. As before mentioned, this bevel gearis guided for rotary motion in the cylindrical recess 81, in which the gearis held by extending lugs or bridge projections 84 extending inwardly from the housing walls of each housing section, and bear .ing under a depending hub portion 85 on the bottom of the gear. The stem 11 which supports the lamp extends out of the casing through anopening 86 in the top thereof.
The bevel gear 26 is rotated forhorizontal swinging of. the light beam through a cooperating bevel gear 87 which is splined on the operating shaft 28. The gear 87 is held against reciprocatory motion by having formed on the. hub thereof a collar 88 which engages in an annular groove 80 formed in the two housing sections. \Vhen the housing sections are assembled, the engagement of the collar 88 in the groove 85) prevents reciprocation of the gear 87 with the motion of the shaft 28, but permits unhindered rotation of the gear 87 simultaneously with the shaft. A key or feather 91 extends inwardly from the bore of the gear and engages in a keyway 92 extending longitudinally of the shaft.
For depressing or raising the light beam, the ball 12' is adapted to be rocked in its spherical socket 83 in the upper bevel gear 26 through a stem 93 which extends upwardly into a cylindrical axial bore 94 in the ball. This stem is rotatable and reciprocal in the ball, and at its lower end is formed with a spherical socket 953 for receiving the ball 96. A nut or bonnet 97 having a spherical depression therein threads over a lateral hub projecting from the end of the stem 03 and completes the The ball 96 is carried on the end of the shaft 28, such as through the medium of the threaded stem98 screwing intothe end of the shaft 28.
In the operation of this embodiment, the rotation of the shaft 28 revolves the upper bevel gear 26' and this, through the medium of the arcuate grooves 34 and pins 35, rotates the ball 12 and lamp 4. The elevation or depression of the light beam can be performed independently or simultaneousl with this rotary motion by thrusting or pul ing on the control knob, the resulting reciprocating motion of the shaft 28 operating through the ball and socket joint 96 and 95 to incline the stem 93 and thereby rock or tilt the ball 12 and lamp 4.
In Figure 8, the operating handle in the drivers compartment has the same universal motion as the lamp supported outside of the car. The lamp is fragnne-ntarily illustrated at 4 and the control handle is designated 101. Extending between the lamp and the control handle is atubular housing or sleeve 102, which may be mounted by a bracket or clamp on the windshield of the car or which may be. extended through the corner rail or windshield as previously described. The windshieldor corner rail may be considered as diagrammatically represented by the dotted lines 103. At either end the sleeve 102 is formed with a bridge 104 extending diametrically across the same, each of these bridge members having central hubs 105 which are internally threaded. Sci-owing into the rear hub 105 is a stud 106 which carries a ball 107 at its end. A nut 108 on the stem enables the stem to be rigidly screwed into the hub 105 and a set screw 100 may be employed for locking the stud in place. The handle 101 is arranged for universal movement about the ball 107 and to this end is formed with a semispherical head 111 which is provided with a semi-spherical socket 112 engaging over the ball 107. To hold the head member 111 on the ball 107, a disc 113 is screwed to the diametrical face of the head 111 by screws 114, this disc having a central opening 115 of spherical curvature which embraces the other half of the ball and prevents the head 111 from being withdrawn or displaced from the ball.
The lamp 4 is similarly provided with a. semi-spherical head 116, the flat face of which is cut on a diametrical plane to enable the head to be readily assembled over a ball 117 on the end of the stem 118 which screws into the fronthub 105. A disc 119, similar to the disc 113, is screwed to the face of the head115 to hold the latter in place on the ball 117. The universal motion of the handle 101 is transmitted to the lamp 4 through a series of rods 121, preferably four innum-ber, which connect the head 111 with the head 116. As shown best in Fig. 10, these rods are equidistantly arranged around the axis of the heads 11 and 116 and to accommodate these various angular motions of the heads 111-116 the ends of these rods have ball and socket mountings spherical depressions 123 in the faces of the two heads 111 and 116. The discs 113 and 119 have openings 124 of spherical curvature which embrace the backs of. the ball tips 122 and retain the latter in the spherical depressions 123. The openings 124 in these discs are flared outwardly at the rear as indicated at 125 to permit extensive angular motion of the heads 111 and 116 without binding on the rods 121..
The lamp is adapted to be locked in any adjust-able position by a pawl 126 which is recessed into the inner head 111 and which is adapted to lock in any one of series of locking holes 127 in the inner face of the ball 107. The pawl 126 is pivoted in a slotted recess 128 on a pin 129 extending transversely -through the head 111. The pawl is adapted to be retracted from the locking holes 127 by the inward depressionof a but ton 131 at the outer end of the control handle- 101. This button 131 connects through a reciprocal rod 132 which has pivotal connection with the inner end of the pawl, the pawl being normally thrust into. one of the locking holes 127 by a compression spring 133 which is 'counterbored in the outer end of the handle 101.
The ends of the tubular housing 102 are' closed by cylindrical shells 135 which screw over the threaded ends .136 of the tubular housing, the outer ends of these shells being contracted spherically to partially embrace the semi-spherical heads 111 and 116. The" conducting cord 137 enters the tubular housing 102 through the opening 138 and extends through longitudinal bores drilled in the ball and stem 117118 and in the head 116. The front part of the ball 117 is cut out as indicated at 139 to avoid pinching of the conductor 137 when the head 116 is inclined.
It will be apparent that any inclination imparted to the head 111 through the handle 101 will be transmitted to the head 116 at the same angleand in like degree through the rods 121-121. For example, a downward inclination of the operating handle employed, as three would suffice and in Fig ure 9, I have illustrated an embodimentemploying only two. In this form the intermediate portion of the tubular housing 102 may be contracted to a smaller dimension by having the reduced number of rods. .The halls 107 and 117 are mounted in lugs 141 projecting downwardly and inwardly from the ends of the tubular housing 102'.- The two semi-spherical heads 111' and .116 have their socket depressions 112 arranged eccentrically so as-to give a greater radius of head below the balls 107'117 for connection with the rods 121. The two rods have pivotal connection with the heads at lower diagonal points thereof, as shown in Figures 11 and 12. The rods 121' have the previous form of ball and socketconnection with the heads, and in the contracted portion of the tubular housing 102 are humped depressing the handle 101 in a substantially vertical plane the rods121 act conjointly under tension or compression to raise or lower lamp 4. Upon' a horizontal motion of the operating handle 101" or any motion upwardly and inwardly as clearly shown in thereof involving a horizontal component one rod 121 will be thrust forwardly and the other drawn backwardly to turn the lamp to right or left as the case may be.
Obviously this lateral swing of the lamp can be combined with any vertical depression or elevation so that the range of adjustment from the handle 101' is substantially univarsal within its field of movement.
In Figure 13, I have shown an embodiment adapted for mounting directly in the windshield or corner rail in a closed body type of car. Figure 13 represents a horizontal sectional view through the body of an .automobile adjacent one end of the windshield, oneof the corner posts or standards for supporting the top being indicated at 144 and a side anel or door being indicated at 145; The g ass 146 has its margin set in a channel rail 147, the edge of the windshield being defined by the channel 147 or by a rail 148 of angular section which abuts-the shoulder 149 on the corner standard 144.
The lamp 4 is supported directly in a ball and socket joint 151-152 which is embodied in the enclosing part of the automobile in order to enable the operating handle 153 to project inwardly into the drivers compart-' socket 152 is constructed of front and rea l sections 154 and 155 which abut on the dianictrical plane of the socket and form '00- operating semi-spherical depressions which combine to produce the socket 152. The two socket sections are preferably, formed with overlappin flanges which thread together as indicate at 156. The channel strip 147 may be so shaped as to embrace the socket sections between this channel strip and the angular rail 148. The front socket section 154 is provided with a flange 156 which overlaps the front of the channel strip and marginal rail, and the rear socket section 155 is provided with a similar flange 157. The
inner spherical faces of these socket sections are provided with annulargrooves 158 extending parallel with the diametrical line of separation between the sections. These grooves are preferably cut so that their lateral walls extend inwardly towards the center of the spherical socket on substantially radial planes, the central groove being formed by unitin half grooves cut in the opposing faces of 0th socket sections.
For locking the lamp 4 in any given position the ball 151 is provided with a plurality of small plungers which are adapted to be projected out of the ball into the grooves 158. As shown in Figures 14 and 15,
face of the front spherical section 161., Each block 167 is normally thrust outward-' ly under the action of a compression spring 169 in the inner end of the guideway. These locking plungers are adapted to be retracted into the confines 'of the sphere 151 by merel thrusting the control handle 153 forward y into the sphere 151. The cylindrical neck portion 171 of the handle is guided for reciprocating motion in the rear ball section 162, and the inner end of this neck portion is threaded for the reception of a I collar 172, which operates in a cylindrical recess 173 in the rear section. Corresponding to the angular position of each sliding block 167, there projects from the collar 172 an inclined arm 174, which engages in a slot in the block 167, bearing on an inclined face inthis slot. Directly in the front of each block 167 is rovided a narrow recess 176 for receivin t e arm 174 when the same is thrust inwar%ly. A compression spring 177 extends from a bore in the front ball section 161 and bears against the end of the handle 153 to normally thrust the handle and cam arms 174 backwardly. It will be noted from the foregoing that by merely thrusting the handle153 forwardly, the .cam
arms 174 retract all of the locking plungers 165 from the annular grooves 158 in the socket and permit the lamp to turn to any position. Upon releasing the handle 153, the same is thrust backwardly by the compression spring 17 7 which acts to thrust the locking plungers 165 outwardly into one or more of the locking grooves 158. The conducting cord is extended backwardl through the ball and socket joint throug alined bores 179 in the lamp stem and in the handle, this cord being led downwardly out of the handle through a hole'181 inter secting the bore 179.
I have shown only two locking plungers 165 spaced at 90. By this arrangement if one of the locking plungers should coincide with the axis of adjustment or inclination of the lamp, the other plunger would nevertheless be in position to lock the lamp by engaging in one of the grooves 158. It will be apparent, of course, that three or even more of these locking plungers 165 could be provided in the sphere 151, and with any desired spacing between the lungers.
WVhere it is desirable that the sp ere.151 be incapable of rotation in the socket 152,
as for preventing the cord 178 from bein twisted off, the sphere 151 may be provide A with a pin projection 182 for engaging in a groove 183 extendin axially of the socket 152 and lamp '4. or cooperating with the locking plungers 155-155, this pin is preferably placed in the position shown in Figure 15, this pin and groove connection between the pawl and socket preventing rot ation of one nelative to the other, but permitting free angular adjustments of the ball into any position.
In Figure 16, I have illustrated a modified .construction wherein the lamp is locked in position b the separation of the two halves of the bal 151. These are arranged for relative sliding motion to and from each other. The socket 152 is constructed similarly to the above socket by the joining of the front and rear socket sections 154'155'.
boss 185 which has a slidable mounting upon an extension 186 projecting from the rear ball section 162. The two ball sections are normally spread apart into firm chntact with the walls of the spherical sockets by a compression spring 187 which is recessed into each ball section. The rear of ball section 162 has a series of locking recesses 188- 'The front ball section 161' is formed with a 191 in proximity to the longitudinal axis of the ha and handle 153', so that the hump will be'able to clear itself of the locking recesses 188 when the handle 153 is thrust inwardly. When the handle 153 is released same manner as above described. This form of ball and socket joint may be also provided with a pin 182 and longitudinal groove 183 to prevent rotation between the ball and socket if desired. Instead of being cylindrical as above described, the extension 186 may be of any polygonal formation for reception in a similarly formed bore in the boss 1 85 so as to prevent relative rotation between the front and rear ball sections 161v162'.
It will be apparent, of course, that numerous-changes may be made in the particular embodiment herein shown without departing from the spirit and scope of the invention.
