AUTOMOBILE-HEADLIGHT.

Specification of Letters Patent.

Fatentetl Nov. il, i919.

Application filed January 4, 1917. Serial No. 140,487.

To all y'ir/ioni 'it may conce/rn lle itlnoivn that l, ll'iLLiaM M. l-loii'roN, a citizen of' the lliiited Stat-es, residing at Cleveland, in the county of Cuyahoga and State of Ohio7 have invented lcertain new and useful liiiprovements in Automobile- Headlights, of which the following is a specification.

This invention relates to headlights, a

`the reflector may have a universal movement iii its casing', and which means is very simple in construction and operation and inexpensive to manufacture. i

Another object of the invention is the provision in connection with a universally supported reflector of electrically operative means for shifting the reflector.

Another object of' the invention is the provision of means for connecting a pair of universally supported reflectors for simultaneous shiftable movement.

In the drawings accompanying and forniingpart of this specification, Figure l is a horizontal sectionalview of a pair o'f conventional headlights, such as those usually used for automobiles with the reflectors thereof connected for simultaneous movement in different directions; Fig. 2 is a frontview of the structure shown in Fig. B; Fig. 3 is an enlarged sectional view of the electric operating means or, motor for shifting the reflectors, this view being taken on line 3 3 of Fig. Q', and looking in the direction of the arrows in said ligure; and Fig. 4 is a detailed sectional view illustrating the pivotally mounted slotted tubes.

Similar characters of' reference indicate corresponding parts in the several figures of the drawings. i

vThe present construction is an improvement iii` part upon my contemporaiieously pemling application.,l Serial' No. 135,321 filed' December 6th 1916. ln that case the -reflector was so supported that an np and a combination of the two within certain limits could be obtained. In the present improvement however, the slotted supporting tubes instead of being` rigidly carried by the casing, are pivotally carried thereby with the result that a greater movement o'f the' reflector in any direction is obtained, so that in View of the compound pivotingof the reflector a universal movement thercoic is the result.

In 'the present improvement, each headlight comprises a( casing` 2 of any suitable design or shape, having a lens 3 attacha'ble thereto in any desired manner. Each casing is provided with a reflector of some suitable forni,-in the present instance the reflector of the right hand lamp in Fig. l is designated as Ll, aii'dftl'ie left land reflector as l-eacli reflector carries the usual bulb or, light connected with the source of electrical energy ni the usual manner, whereby the light is movable with the reflector. Each reflector is provided with a pair'of oppositely located pivot pins 6, each loosely supported by a pivot ball 7, each of' which balls is movably carried in a slotted member or tube 8. pivotally secured as at 40 to the inside wall of the casing. This compound pivot construction permits the reflector to swing up or down on its pivot pins relatively to the balls, which support such pins and also permits the reflectors to be swung in a direction transverse to its up and down movement due to theinovement of the pivot pins and balls within the slotted tubes, and also permits the reflectors to be swung by a combination of these two movements in suoli a way that the light may loe thrown into different angular positions, so that when the reflector is thrown down the glare of the lamp will be entirely prevented, while when thrown sidewise., a better View of the road is obtained, especially when going around corners or curves, while when these two move,- nieiits are combined sign posts can be read,

thus insuring greater eflicieiicy in the use of the headlights. For swinging the reflectors up and down, or to return them totheir horizontal position, one of' the reflectors, as

i connected by a rod 9 through the mediiiiii of a universal connection O,-as by a ball and socket with an eccentric 1l, mount-- ed on a shaft l2, on which is secured a ratchet 'Wheel .13 adepte@ t@ he engaged by a pair of arms f The opposite A accts as at lo into a slot er plu Werlil1 whereby on' the of the core baci: and torth the nl be operated to rotate the ratchet it beine' maintained in operative enent with such ratchet wheel by a lll secured to a bracket Zbfasteucd to r ol the casing` il. This bracket snplie several parts of the motor mecha- The spring` Si is in position to i plunger 18 to its wasn or l'zacltward by the magnet :'Zl, .rich carried by the bracket adjacent to c core or plunger. The ratchet wheel is maintained against.slippingbackward by a suitable spring' pawl 19, also carried by the bracket 20. The core 18 has a. contact memq ber at vforward end in position to make contact with a similar contact ine iber :7.3 carried by a springV member supported on a rigidly upstanding member insulated 'from the `bracltet 20. The springjlll is in position to always return the core or plunger 17 to torwarrd position to make contact with the armature or spring' contact member Qla'fter such core 18 has been drawn to the rear or backward by the magnet, ln other words, the springl 19 acts through the pawl ll to -return the core or plunger into position to malte contact after such contact is broken the clectroanaejnet means, so that t" snisir. out in operation tous inane and break ben `ions 'of the core l? and nus rotate the ratchet f through the with w i ry or downwardly to the de# tent, the rellector at this time swing'- pirot pins relatively to the balls. will of course be understood that the necil' ons and electrical connections to describe herein are provided i oper operation of the electro- .fr further detail descripand the trical co necnnnecessary herein 'in r y contempo sii'ed ing on its lt The two reeetors are connecting rod 26 shown as `ir of rods coupled together :27, each inem-ber otl the pair g; im v.rally connected with an ear or lug :ecured to the reflect-or. The rod 26 eX- Lhronrh enlarged or slotted openings the lanip carvings, so that when the 'fte-d up down the com i L'l' 'will more therewt 5G is placed in the p np aan t;

yard position when it has been drawn sary-rae setting of the motor just described, and Van eccentric 3l which is similar to the eccentric ll hereinbetore referred to, is therefore located at right angles to the eccentric ll, it being' likewise suitably connected by links 32 with the connecting' rod jfl connecting the two reflectors. or a sleeve 2G thereof, whereby on the operation ot the motor in a similar manner to the motor 30 hereinbel'ore described, the reflector -l will be shifted at right angles to its up and flown movement due to the shifting ol the balls in the tubular members or raccways, one in one direction and the other in the opposite direction, that is, one forwardly and the other rearwardly, and consequently through the connectiingrod 26 the companion reflector l. will also be shifted in a similar manner. To insure the proper parallel movement ot' thereectors, they are also connected by a connecting rod 33, comprising` a pair of members coupled together by a coupling member 8l, one of the rod members as 35 being linked by a pair of links 36 to one of the reflectors shown herein as the reflector l. This rod 33 eX- tends through enlarged openings or slots 37 in the two casings. The linkage connection 36 provides the proper flexible connection between the two reflect-ors to permit proper' movement thereof when shifted, while the universal connect-ion or some similar flexible connection l0 provides the necessary connection to permit movement ot the reflectors by the motor 30 in a manner which will be r adily understood. Each motor will bev controlled by a proper switch and when the switch ot' the motor 30 is operated, both reflectors will be swung' up or down from their horizontal position in the manner desi-red and when the switch of the motor 30 is operated, both reflectors will be swung sidewise or transversely of their up and down movement. Obviously by operating both switches simultaneously, the reflector may be shifted into any desired angular position relatively to the casing by reason of the compound pivoting of the reflector on the easing, so that not only an up and down moverent and a sidewise movement of the reflector may be obtained, but alsoia universal moreinent thereof, since the reflector isnot only shiftable by reason of its pivot G, up and down and sidewiso by reason of the ball pirot 7, but by pivotingr the slotted tubes on the casing these can also swing so that, as stated, a universal movement of the reflector is made possible, since each compound pivot for each reflector comprises a pair of rotary pivot members connected by a movable pivot member or ball. ln other words, ythcpivot pins o rotate with relation to the balls, while the pivotal connections Jf() enable the slotted tubes to rotate with relation to the casing, these two rotary pivotal connections are in einer couiviletl together by the Sbiftable balls T. which move lengthwise ot' the slotted tubes.

lt will be understood that the various details may be more or less changed without departing from the spirit or scope of the present improvement.

Like in v companion case hereinbefore last referred to. the pawls may be operated mechanically instead ot' electrically if preferred.

it will of course. be understood that the slotted tubes maintain the balls in propel'l position, the slots of the tubes being of suitable width to receive the pins (S and prevent the improper displacement of the balls.

It will be observed that in the present iinprovement the reflector is itself directly connected with the casing, thus doing away with all intermediate connections7 such as annular members, etc., by compound pivotal means, thus materially simplifying the mechanism and reducing` the expense of manufacturing the same. lt will also be understood ot' course that the switches for controlling the motors can be located in any desired place, on the steering wheel or dash board of the vehicle. In practice, of course, the connecting rods between the two reflectors maybe located closer together and in fact may run through a suitable tube, i'f desired.
