light rays whereby glare is eliminated at the will of the operator.
A further objectof the invention is the provision of a shield movably mounted adjacent a lamp in the headlight which is .adapted to be operated electrically and at the will of the driver of the machine.
This invention will be best. understood from a 'consideration of the following detailed description, in view of the accompanying drawing` forming a part of the specification; nevertheless it is to be understood that the'invention is not confined to the disclosure, being susceptible of such changes and modifications .which shall define no material departure from the salient features of the invention as expressed in the appended claims. v
s .In the drawings: I
i Figure 1 is a vertical section of the headlight showing my invention applied thereto.
Figure 2 is a rear view in elevation of the operating means forthe movable shield.
Figure 3 is a fragmentary enlarged detail of an'element of the operating means of the shield.
Figure 4 is a view in perspective of the shield.
Referring more particularly to the drawings, 1 designates a parabolic shell forming the reflector of the headlight. Located along the axis of the reflector is a lamp 2 removably mounted in the socket 3 formed at the rear of the reflector 1. The shell or reflector 1 is provided with a slot 4 in which is movably mounted a block 5 secured upon an arm 6 of a movable shield 7. This shield in its operative position as shown in Figure 1 is adapted to be located directly above the lamp 2 with a triangularly shaped lip 8 disposed Within the direct rays of the lamp and along the axis of the para-- bolic mirror. The shield is curved as shown more particularly in Figure 4 and its rearwardlyV projecting arm 6 is pivoted jas shown at 9 to a bracket 10 secured to the rear wall of the shell 1. y
The block 5 which is connected with the shield 7 and movable through the slot 4 in the reflector 1 is provided with a longitudinal bore shown at 11 into which is partially projected a conically shaped roller bearing 12 adapted to engage the flat side 13 of a conically shaped cam member 14 which is movable into the bore 11 but has its longitudinal axis located at one side of the center of the bore so that as the cone-shaped member is moved through the bore 11 it will engage the roller 12 and force the block 5 outwardly and raise the shield 7.
The base of the conical member vis cylindrical as shown at 15 and provided with a concaved groove 16 adapted to be engaged by a ball 17 forced outwardly by a spring 18. The spring is maintained in place by a threaded plug 19 screwed into the openling 0f a passage 2O in which the' ball and springs are mounted. The inner opening of the passage 2O is of such a diameter that the ball 17 will be prevented from being dis charged from said passage. y
A pair of solenoids 21 and 22 are secured by means of brackets 23 to the back of the casing 1 and are electrically connected to a source of current on the automobile for moving the armature 24 back and `forth depending upon whether the electrical circuit has been closed to the-solenoid 21 or to the solenoid 22. The armatures are silidable in a core running longitudinally and cent-rally of the solenoids 21 and 22.
The operation of my device is as follows:
When it is desired to modify the rays of light from the headlight to eliminate glare a switch is closed to place the solenoid 21 in circuit and the armature 24 is moved into said solenoid whereby the cone-shaped member 1:4 is withdrawn from the passage 11 in the block 5 and permitting the shield 7 to drop into the position sho-wn in Figure 1. The switch is lthen open whence the shield will remain in place. When it is desired to return the shield 7 into engagement with the inner wall of the reflector l the circuit to the solenoid 22 is closed thereby energizing the same and causing the armature 24 to be moved into said solenoidand forcing the cone-shaped member 14 into the passage 11 so that as the flat side 13 of said mem'- ber rides against the roller 12 the block 5 will be moved outwardly raising' said shield and the cylindrical memberl l5 is moved to a position Where the spring pressed ball 17 Will engage the groove 16 and lock the shield in place to prevent rattling oi the same. The current to solenoid 22 is cut off. AZhen the solenoid 21 is energized the cone-shaped member Will be returnedto the' position shown in Figure 2 and permit the shield to fallf so that the undesirable rays of the hea-dilight Will be cut off not only by the shield per se but by the triangular projection 8.

A headlight comprising a casing, provided with a slot, ashield provided with an `arm projecting through the slot pivota-lly mounted on: they back vof the casing, a block secured to the arm movable through the slot and provided with a. central passageya pair of spaced solenoids and a single armature movable in the solenoid, a cone-shaped member on the armature and adapted to be moved into the passage in the block and located eccentrically of the passage in 4the block, said cone-shaped member when moved intothe passage in the block engaging the Walls of said lpassage and causing the block tobe elevated and likewise the shield.
2. A headlight comprising a casing provided With a slot, a shield provided with an arm projecting through the slot pivotally mounted on the back of the casing, a block secured to the arm movable through' the slot and provided with a central passage, a pair of spaced solenoids, and a single armature movable-in the solenoid7 a cone-shaped member on the armature and adapted to be moved into the passage in the b-lock, said cone-shaped member When moved into the passage in the block engagingthe Walls of said passage and causing the block to be elevatedI and likewisethe shield and' located eccentrically of the passage inf the block, said cone-shaped member being provided with a groove, and means in the'blook engageable with the groove forlocking the cone-shaped member in a' predetermined position.
3. headlight comprising a casing provided with a slot, a shield provided with an arm projecting through the slot pivotally mounted on the back of the casing, a. block secured to the-arm movable through 4the slot and provided with a central passage, a pair of spaced solenoids, a-nda- Single-.armature movable in the solenoid, a coneshaped member on the armature and adapted to' be moved into4 thel q oassa'geI inf the block and located eccentrically of tlienpassage in the block, said cone-shapedV member having a flat side, and a roller mounted in' the block and projecting into the passage adapted' to engage the flat side-y of the cone-shaped member.
4L. A headlight comprising a casing,I a bracket onf: said casing,- a-shi'eld pivoted to the bracket, a block having. af transversepassage secured to the shield, a cones'hape'd member movable in the passage, means vfor moving the coneshaped' member in' opposite ydirections in tliepassage, the4 inclined sides of the cone-shaped member being adapted to engage the Walls of the4` passage VWhen the cone-shaped member is longitudinally moved'4 in the passage for causing the block to be elevated and likewise 1 the shield.
5. A headlight comprising. a.- casingl hav]- ing a slot, a bracketon said casing,,a'shield having anarm extendingA through the slot pivotally connected with the. bracket, said block being provided with a central passage, a rod mounted eccentricallyandj longitudin'allyy of the passagein the block,A a coneshaped member on the rod adapted toA be moved into the passage inf the block-and located eccentrically oi the 'passage in' the block and when engaged' byy tlief'wallsv of the passa-ge saidblock Willfber elevated and thereby elevate the shieldl AJOHN Roe-ERT sroNnY..
