LAMP ATTACHMENT.

To all lwhom t may concern.'

Be it known that we, CHARLES F. L. Harriman, WALLER L. KAUFMANN, and (Jani. ll. KAUFMANN, all citizens of the United States, residing at Santa Ana, in the county ot' Orange and State ot' CalitorniaJ have invented new and useful lmpi'ovements in Lamp Attachments, of which the following is a specification.

rl`his invention relates to improvements in vehicle lamps oic the type known as spot lights, and resides in the provision oi' means for cooperation with the universal mountings oi such spot lights, whereby the upward vertical movement ot a lamp when the latter is in a certain position in its range so that when the lamp is in position to cast.. its rays directly 'forwardly in trent of the vehicle to which it is attached it will not and cannot be tilted or moved vertically,upwardly to such extent that its rays will blind or con- Afuse operators of vehicles or pedestrians in the path of the vehicle to which the lamp is attached. i

ln a great many ot' the States throughout the country laws have been adopted-regulating the iocus of spot an(1 head lights for automobiles in order to prevent accidents due to drivers of vehicles and pedestrians becoming blinded and confused by the glare of approaching vehicle head or spot lights; and to this end it is usually necessary to dispose the lamps in such position that their co of rays will strike the road at a distance ot' sh from forty to seventy-five l'eet in iront of th the vehicle to which they-are attached. dlt has been found that lights arranged to throw their rays upon the road within these distances do not prove objectionable to other drivers or pedestrians nor glare to any appreciable extent. lt is the primary object of this invention to provide a means of the above mentioned character for use in connection with spot lights which, as a rule are universally mounted; such means acting when the spot light is in road-illun'iinating position to prevent movement of such spot light upwardly past the point that-would cause its rays to be projected upon the road a Idistance farther than determined upon, for example, sixty feet, and in carrying out the invention the means above mentioned is Specification of Letters Patent.

vided with a rearward extension 6 located centrally ,tereof and which serves as a handle and as a means for connecting the electrical conductors, 'not shown thereto. Depending from the extension 6 is'the post or standard 7 which is reduced as at 8 adjacent to its lower end and deines an annular shoulder 9. rlfhe reduced portion 8 is mounted for rotation within an upright split sleeve 10, said sleeve having opposed" wings 11 through which a thumb screw 12 is extended. By tightening the thumb screw 12 the sleeve 1U 'will bind upon the' reduced portion 8 of the post 7 and hold said post in position. vThe sleeve 1() is provided intermediate ot its ends with an oli;- set portion which is formed into a split sleeve 13 being disposed at right angles to the sleeve 10 and which is rotatably mountedA upon the outer end of the bracket 2. The

' outer end of the bracket 2 is reduced as at 'la and screw-threaded as at 15 so as to receive a nut 16; the nut 16 holding the sleeves 10 and 13 which constitute the body or essential part of the universal joint, in rotatable relation upon the bracket 2. bracket 2 is secured by fastening elements such as screws 1'? tothe vehicle A.

i Ordinarily alamp such as hereinbei'ore described is adjusted so as to cast its rays at the desiredpoint upon the road in front of the vehicle to which it is attached and f when so adjusted may be held in such position'by tightening-the nut 16 and the thumb screw 12. By looseningthe thumb' screw.

12 the lamp may be turneddaterally upon its mountings and by correspondingly loosening the nut 16, may be ijotated vertically as desired so that said lamp may be moved to throw its rays in any desired direction.

ln carrying out our'invention, which is generally indicated inthe drawing by the reference nun'reral 1l there is provided, means for ln'mting the movement ot the lamp when it is in road-illuminating position so that it cannot be velevated to such a degree as .to throw its light rays at an elevation vwhich would produce a blinding and glaring effect for the drivers of vehicles approaching or in the path of said rays, and to this end there are preferably' provided stop\ members 18 and 19 mounted respectively upon -the' post? and bracket 2 for the lamp, such memtioned upon the bracket 2 so that its lug 24 is'upright and has its outer end face disposed in and approximately horizontal plane as shown in Figs. 3 and 4 of the drawing, whereas the member 18 is so mounted upon the post 7 that one of the side faces of the lug 24- is adapted for engagement with andto rest upon the end face of the lug of the member 19, and it will therefore be seen that this engagement of said members provides for the limiting ation desired to prevent upward movement of the lamp so that its rays will not prove blinding and confusing for the drivers of other vehicles and for pedestrians.

By loosening the screwsl 23 the members 18 and 19may be turned or adjusted upon their respective mountings as desired, so that the pitch' of the lamp or rays of the lamp maybe varied. When the member 19 is turned vso as to 'bring the lug'rearwardly of its upright position` the lamp may be tilted upwardly tov a greater extent than when said lug` is'in upright position, and when said member 19 is turned so as to bring its lug forwardly of its upright position said lamp will not be permitted upward movement to the extent so permittedwhen the lug is in upright position. l/Vhen the member 18 is adjusted. the point in the range of lateral adjustment of the lamp at which the limiting ot' the upward movement is pro-' vided, may be varied. Therefore it will be that should it be desired `to swing the lamp slightly. to one side or the other of,

the position which is substantially in line with the longitudinal 'axis of the vehicle, lsaid position being the normal position, and when it is desired to have the upward adjustment or novcmcnt of the lamp limited ina position to one side or the other of the normal position of the lamp, this may be effected by turning the member 18 upon its mounting so as to bring the lug 2-1 thereo intorequ'ired position for the desired limiting action.

The member 19 is interposed between the ico braclget shoulder 25 and adjacent end face l of the sleeve 13, such end tace having en"- gageinent' with said shoulder 25 in' the absence of the member 19. By tightening the nut 16 the sleeve 18 binds upon the member 19 and holds it securely in place, and it *,will be seen also that member 19 may be iso tion the lug Q4 of the ment of great value i,sec,ees

tion shown in Fig. 1 ofthe drawing, such position being the normal or road-illuminating position, when it is desired to swing the lamp t0 one side or the other, this may be done by grasping the extension 6 and turning the lamp laterally until the lug Q5: of the member 18 moves out of engagement with the lug 241: or' the member 19. At this timethe lamp is free to be tilted up or down t0 its full extent, inasmuch as the lugs are out of engagement with one another andthe lamp is not directing its rays straight ahead. It will thus be seen that the lamp may be moved into any desired position laterally, upwardly, or downwardly, when it is turned out or' roadilluminating position. When the lamp is againV brought to road-illuminating posi member 18 will rest upon and engage the lug 24 of the member 19 and the upward movement of the lamp is thus limited so as to pre- 'vent glaring rays from the lamp from confusing the drivers of other vehicles and pedestrians in the path of the vehicle to which the lamp is attached. .Therefore it will be seen that the lamp is prevented upward movement past a point which is near;

althoughpret'erably and usually out of necessity, owing to the mounting oi' the lamp, below the horizontal, only when such lamp 'is disposed at a certain point of its range oi' movement, such point being arrived at when the lamp is in road-illuminating position. With reference to the foregoing description and the accompanying' drawing, it will be seen that we have provided an improvein spot lights for ve hicles suchv as automobiles, and that such improvement will permit of the use of a great number of spot lights which under ordinary conditions and in a great many sections of the country couldnot be lawfully used.

Having thus disclosed our invention, We

l claim and desire to secure by Letters Patent:

l. A lamp mounting including a bracket arm, a post arranged at an angle'to the bracket arm, rigidly connected sleeves receiving` the bracket arm and post and rotatable upon the respective members, and cooperating stop members carried by the` bracket arm and post `for limiting' the swinginp; movement of the mounting in one direction.

2. A lamp mounting including a bracket arm, a post arranged at an angle to the bracket arm, rigidly connected sleeves receiving' the post and bracket'aim and rotatable thereon, rings clamped upon the bracket arm and post, and cooperating stop lugs carried by the rings and arranged to engage each other to limit the swinging movement or the mounting in one direction.

3. A vehicle lamp, comprisinga post to which the lamp is attached, a bracket, a mounting comprising sleeves disposed at right angles to one another, one of said sleeves being` rotatable upon the bracket,

said pest being,` rotatably mounted in the ing including integral sleeves having one` sleeve rotatably mounted upon said bracket and the other sleeve rotatably receiving said post, split rings mounted upon said post and bracket and held in place by said sleeve, screws for clamping` the split rings in position, and lugs upon said split rings adapted to engage one another and to prevent upward movement or the lamp when the latter is in one of its various positions.

ln testimony whereof, we have signed our' names to this specilication Ain the presence.
