SPOTLIGHT.

Application filed March 25, 1921. Serial No. 455,616.

To all whom it may con-007%:

Be it known that I, HENRY H. Mo zn'roN, a citizen of the United States, residing at Santa Monica, in the county of Los Angeles and State of California, have invented a new and useful Spotlight, of which the following is a specification.

This invention is a new and useful device for controlling the direction of projection of a beam of light, emanating from a spotlight lamp of the type commonly employed on motor vehicles. I

One of the objects of the invention 1s to provide means for supporting a spot light lamp in such manner, that its beam may project to any desired part of the roadway, in advance of the vehicle to which it 1s attached, and which may not be projected upwardly at such an angle, that it will direct the beam into the eyes of thB dI'IVBI: of an approaching vehicle. A further ob ect is to so mount the lamp that when it is turned to direct its beam laterally to either side of the roadway, it may also be directed upwardly at any angle, for the convenlent reading of sign posts, house numbers and the like.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view illustratlng the lamp in position to project its beam straight ahead, and tilted upwardly to the limit of its movement while in this position. Figure 2 is a side view. Figure 3 is a top plan view illustrating the lamp in position to project the beam to the left. Figure 4 is a similar view illustrating the lamp in position to project the beam to the right. Figure 5 is a view similar to Figure 4 with the lamp tilted upwardly. Figure 6 is an enlarged detail view illustrating the lamp carrier member and the limiting stop.

Referring to the drawing, 10 designates a clamp formed of two members shaped to engage any desired part of a motor vehicle,

referably the windshield frame 11. As illustrated, the clamp consists of two complemental members, held in clamping position by a bolt 12, which is provided at one end with a split socket 13, and at the other end with a threaded portion to receive the nut 14. Said socket is positioned to extend horizontally, and receives and clamps one end of a support arm 15, the other end of said arm having a socket 16, the bore of which extends parallel with the bolt 12.

Rotatably mounted in the socket 16 is a carrier member 17, provided with a shoulder 18, hearing against the forward face of the socket 16, said carrier member being retained in position by a nut 19. The forward end of the carrier member 17 is provided with a socket, having a bore at right angles to the axis of rotation of the carrier member.

The. spotlight lamp 21 is conventionally shown, and may be of any standard or preferred type. In the drawing it is illustrated as rigidly mounted in a ring 22, formed on the end of an arm 23, the lower end of which is provided with a socket 24. A pivot bolt or pin 25 connects the socket 24, of arm 23, with the socket 20 of the carrier member, in such manner that said arm 23 is free to rock on said axis. The socket portion of the arm 23 is provided with a stop lug, which is positioned to bear against the forward face of the socket 16, of the carrier member. The bolt 25 is approximately in line with the axis of rotation of member 17, but at right angles thereto.

Referring to Figure 1 it will be noted that the lamp is illustrated in position to project the beam straight ahead. While in such position it may be tilted downwardly to any desired angle, and upward tilting thereof is prevented by reason of engagement of the sto lug 26 with the forward face of the soc et 16. Thus, while the beam is projected straight ahead, it is impossible to elevate it to such an angle that it may be projected into the eyes of an approaching driver, and yet it may be brought sufficiently high for proper illumination of the roadway. When it is desired to project the beam to the left, the carrier member 17 is rotated to the right upon its axis, as illustrated in Figure 3, and the lamp may be rocked upon the pivot bolt 25, to direct the beam to the desired point. By so rocking the carrier member 17 on its axis, the beam may be projected to any desired height, and at any necessary angle. Likewise when it is desired to project the beam to the right, the carrier member is rotated to the left on its axis and the lamp may then be rocked upon the pivot bolt 25. By so rocking the carrier member on its axis the lamp may be brought to any desired pothe" stop sition necessary to read sign posts or house numbers. See Figures 4 and 5. It will be noted-however, that just as soon as the lamp is brought to the forward position illustrated in Figure 1, the stop lug 26 will pre: vent elevation of the beam beyond a predetermined angle. It will also be noted that when the lamp is turned to the side positions,

lug will not interfere with its manipulatlon to direct the beam upwardly or downwardly at any desired angle. In other words, the lamp is normally capable of universal adjustment, except when the beam is directed in a predetermined direction.

From the foregoing it will be observed that by means of the invention, a simple and inexpensive spot light is provided, having means whereby the beam may be projected straight ahead, and yet be prevented from being tilted to such an angle that it will be directed into the eyes of an approaching driver. In addition to this, by simple manipulation, it is easily possible to direct the beam laterally at any desired angle.

Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. A spot light support ofthe character described comprising a horizontally disposed axially rotatable carrier member, a lamp support having one end pivoted to the carrier member on an axis positioned approximately in line with the axis of the carrier member and at right angles thereto, whereby the pivot axis of said arm may assume horizontal or vertical positions or any intermediate angular position therebetween, lamp supporting means on the free end of said support, and means limiting vertical pivotal movement of the lamp support on the carrier b member and supportabove a predetermined angular position when the lamp is directed forwardly. V

2. A spot light support of the character described comprising a horizontally disposed axially rotatable carrier member, a lamp support having one end pivoted to the carrier member-on an axis positioned approximately in line with the axis of the carrier member and at right angles thereto, whereby the pivot axis of said arm may assume hori zontal or vertical mediate angular position therebetwecn, lamp supporting means on the free end of said support, a fixed abutment, and a stop member carried by the lamp support and positioned to engage said abutment to limit vertical movement of the lamp on the carrier member and support above a predetermined angular position when the lamp is dirccted forwardly.

3. A spot light support of the character described comprising a horizontally disposed carrier member provided at one end with a socket having a bore at right angles to the axis of said member, a lamp support, a pivot pin mounted in said socket and engaging one end of the lamp support, means for rotatably supporting said carrier member, whereby said pivot pin may assume horizontal or vertical positions or any intermediate angular position therebetween, lamp supporting means on the free end of the support, and means limiting vertical pivotal movement of the lamp on the carrier member and support above. a predetermined angular position when the lamp is directed forwardly.

4. A spot light support of the character described comprising a support arm provided with a horizontally disposed socket, a carrier member axially rotatable in said socket and provided with a socket the axis of which is approximately in line with the axis of the carrier member and at right anglesthereto, whereby the axis of said carrier member and socket may assume horizontal or vertical positions or any angular position therebetween, a lamp support, a pivot pin connecting one end of said lamp support with the socket of said carrier memer, lamp supporting means on the free end of said lamp support, and means limiting vertical pivotal movement of the lamp on the carrier member and support above a pre, determined. angular position when the lamp is directed forwardly.

In testimony whereof I have hereunto set my hand.
