D S T T E AUTOMOBILE HEADLIGHT.

Application filed November 1,1828. Serial No. 145,449.

This invention relates to adjustable headlights of the search or spotlight type and especially to improvements in the mounting and adjusting mechanism employed. 7

The object of the present invention is to generally improve and simplify the construction and operation of a headlight of the character described; to provide a mounting which permits the head-light to be positioned and secured in front of the radiator of an automobile; to provide a mounting which permits the light or beam projected to be moved through a wide range and further to provide an actuating mechanism whereby movement of the beam or light may be readily controlled.

One form which the invention may assume is shown by way of illustration in the accompanying drawings, in which:

Fi re 1 is a central vertical longitudinal section through the -head light,

Figure 2 is a diagrammatic view showing the range of movement of the projected beam,

Figure 3 is a front view of the radiator of an automobile showing the head-light attached thereto,

Figure 4 is a side elevation of Figure 3,

Figure 5 .shows a modified form of the structure disclosed in Figure 1.

Referring to the drawings in detail and particularly to Figures 3 and 4, A indicates the radiator of an automobile, B the spout and radiator cap and C the head-light forming the subject matter of the present application. The headlight proper is best illustrated in Figures 1 and 3. It consists of a substantially cylindrical-shaped housing 2 provided with a back section 3 and a front window or lens 4 which is attached or secured to the housing in the usual manner. Disposed centrally of the back section 3 is a bearing member 5 and journaled therein is a shaft 6, the function of which will hereinafter be described.

Suitably secured on the forward end of the shaft or that portion which extends into the housing is a bracket member or socket 7 and carried thereby is a parabolic reflector 8 and a surrounding ornamental or covering plate 9, the plate 9 being formed into :11 with the reflector 8, as here illustrate or being suitably secured thereto, if desired. The socket 7 may be of suitable constructlon and is adapted to receive and secure a 5i plug 10 of an ordinary electric lighting bulb such as indicated at 1 A contact ring 12 is mounted on the inner end of the socket or bracket member 7 and is insulated therefrom as indicated at 13. A wire 14; connects the ring with the terminal of the plug 10 and the plug proper forms the return circuit, that is, a grounded single wire c rcuit is here illustrated, but any type of circuit may be employed, as it does not form any part of the present invention. A yielding brush 15 carried by the back section of the housing delivers the current to the ring and the bulb and the single wire 16, in turn, supplies the brush, an arrangement of this character being more or less essential as the ring and the insulating member rotate in unison with the shaft 6, the socket 7 and the reflector 8, as will hereinafter be. described.

The stationary housing is secured in any suitable manner in front of the radiator A. In this instance, a forked bracket 17 is employed, this being, in turn, secured to a forwardly extending arm 18 which is secured to the radiator spout B as indicated at 19. This form of adjustment forms a rigid sup port for the lamp housing, but any other suitable support may be provided, as long as. care is taken that the lamp housing is rigidly supported.

In order that the shaft 6 may be rotated, means must be provided which may be controlled by the operator from the drivers seat. The means illustrated in the present instance is a rod 20. .This rod extends through the radiator and is run in under the engine hood. From there it is passed through the instrument board and the inner end is provided with an operating handle 21 which may be positioned within convenient reach of the driver. The outer end of the rod is provided with a universal joint 22. A similar joint 23 is attached to the inner end of the shaft 6 and these joints are connected by means of an angularly disposed opposite to that shownin Figure 1. "By di s shaft-24. A simple easily operated connection is thus provided in conjunction with the shaft 6 whereby the operator or driver may transmit a rotary motion to the shaft.

In actual practice the parabolic reflector s so positioned with relation to the longitudinal axis of the lamp housing and the shaft 6 as to throw the projected beam to one slde of said longitudinal axis or so as to slightly overlap the same. This is best illustrated in the diagrammatic view shown in Figure 2. \Vith the headlight attached to the radiator as shown in Figures 3 and 4 and with the head-1i ht beam projected a 'ainst a surface forwardly of the car, a circu a-r lighted area will appear as indicated by the circle 27, that is, when the reflector assumes the posi tion shown in Figures 1 and 2. If the shaft 6 is rotated through an angle of 90 to the left, a lighted area such as indicated by the circle 28 will appear. If rotated through an angle of 90 to the right the area indicated It rotated trated, and as the shaft may be rotated to any degree desired, it is obvious that the projected beam may assume any intermediate position desired, for instance, those indicated by the circles 31, 32, 33 and 34. If

the reflector was stationary the only field of vision obtainable would be the area included within the circle 27.

Not so in the present instance, as the reflector is rotated in unison with the shaft 6 and as such permits the projected beam to be swung into any position desired and a complete field of vision ma be obtained within the circular area indicated by the large circle 35. A wide range of vision is thus obtained by merely disposing the reflectoron an' angle and rotating the same about a fixed longitudinal axis.

The ornamental or cover member 9 is cir- .cular in outline and concentric with the furthermore gives it the appearance of the ordinary stationary parabolic headlight reflectors nowin use. The general design of the headlight may thus conform to, other headlight equipment employed without interfering with the general construction and mountin of the reflector 8.

By re erring to Figure 5, the modified form of the structure is disclosed. In this instance', the reflector 40 is also disposed-Jon an angle, to. the shaft. '6'; but the angle is posing the reflector on the angle shown in F1gure 5 a larger reflecting surface may be obtained, and the cover member 9 may be naled in the housing, and a parabolic eliminated. The reflector 40 is an ordinary parabolic type of reflector, but its. outer peripheral edge 41 is cut on an angle with relation to the longitudinal axis of the reflector, thereby obtaining an increased rethat it may be employed on motor boats,,

ships, and in fact wherever headlights of this character are required. I similarly wish it understood that various changes may be resorted to within the scope of the appended claims and that the materials and finishes of the several parts employed may be such as the manufacturer ma decide or varying conditions or uses may emand.

, Having thus described my invention what I claim and desire to secure by Letters Patcut is 1. A head-light of the character described,

cylindricalourli ht reflector secured to said member-and is-, posed within the housing, the. longitudinal axis of said reflector being disposed at a predetermined angle to the longitudinal axis comprising a substantially shaped housing, a rotatable member of the rotatable member and the housing and maintaining said predetermined angle durin' rotation of the rotatable member.

'3. A head-light'of the character described, comprising a substantially shaped housing, a filler plate disposed in the outer end thereof, a parabolic reflector eccentrically positioned with relation to said plate, the longitudinal axis of said reector being disposed onan angle to the longitudinal axis of the housing, and means for rotating the reflector and the filler plate.
