- attains LAMP MOUNTING.

Application filed March 29, 1922. Serial No. 547,846.

To all whom it may concern:

Be it known that we, CHARLES F. L. :KAUFMANN and VVALLER L. KAUFMANN, citizens of the United States, residing at Santa Ana, in the county of Orange and State of California, have invented a new and useful Lamp Mounting, of which the following is a specification.

This invention relates to adjustable mountings of the character employed 'on motor vehicles for supporting spot-light lamps, and an object of the invention is to provide a construction whereby the spot light can be readily turned about a Vertical axis so that the light rays may be projected in different directions.

Another object of the invention is to provide a construction that is well adapted for use on an enclosed car and that will permit the turning of the spot-light from within the car.

The invention may be embodied in different forms, and two such forms are illustrated in the accompanyin drawings:

Figure 1 is a plan view of a lamp mount-- ing embodying the invention in one form, a lamp being shown supported by the mounting and the mounting being attached to a vehicle body, a fragment of which is shown in section. The lamp is directed forward in solid lines and is indicated in a different position in broken lines.

Fig. 2 is a front elevation of Fig. 1, the vehicle body being in section in a plane passing through the bearing mounted in said body. 7

Figs. 3, 4t and 5 are enlarged sectional details on the lines indicated by 33, 14, and 55, respectively, Fig. 2. W i Fig. 6 is a plan view of a lamp mounting embodying the invention with modified structure, the lamp being shown in one posi tion in solid lines and in a different position in broken lines; and the mounting being socured to a vehicle body.v a fragment of which is shown in section.

Fig; T is a front elevation of Fig. 6, the vehicle body being in section on a vertical plane passing through the bearing for the drive shaft.

Figs. 8, 9. and 11 are enlarged sectional details on the lines indicated by 88, 99, 1010, and 1111, respectively, Fig. 7.

Referring to the drawings there is provided a bracket 12 comprising a stationary section 13 and an adjustable section 14.

The sections 13, 1 1 are hinged together by a bolt 15. The section 11 is provided with a split bearing 16 so that wear can be compensated for by tightening the screw 17. J ournaled in the bearing 16 is a rigid shaft section 18 which is preferably slightly bent, as seen in Fig. 2.

On the upper end of the shaft section 18 is mounted a lamp indicated in general by the character 19. This lamp may be of any suitable construction and the details thereof are not a part of this present invention. In this instance the lamp is electrically operated and the lamp leads are shown at 20 for supplying electric current to the lamp.

The shaft section 18 is provided with a shoulder 21 which rides on the upper face of the bracket section 14, said shaft section having a reduced portion 22 where it passes through the bearing 16. The shaft section 18 is provided just beneath the bearing 16 with. a collar 23 which may be secured to the shaft section by a pin 2%, or other suitable means. This collar 23 prevents the shaft section 18 from being withdrawn rom the bearing. Because of the shaft section 18 being bent, it is clear that the axis of the lamp 19 will tilt with respect to the horizontal when the shaft section 18 is turned to swing the lamp into different positions.

Now referring more particularly to Figures 1 to 5 of the drawings, the bracket section 13 is secured to a face plate 25 that is fastened by screws 26 to the vehicle body indicated at 27.

The body 27 is provided with a hole 28 to accommodate a bearing 29. The bearing 29 is in the form of a bushing having a head 30 at its outer end and screw threaded at its inner end for engagement with a tubular nut 31. he nut 31 holds the bear in; securely in place.

A se -ond shaft section 32 is positioned at an angle to the section 18 and is journaled in the bearing 29 and is provided at its inner end, which projects inside of the vehicle body, with an operating member 33 whereby the shaft section 32 may be turned. The shaft sections 18, 32 are connected by a flexible sha 't section comprising a series of links 34:, 35, alternately arranged... The links 3 1 form ears 36 at its opposite ends and the opposite ends of the link are furcated at 37 to receive the ears 36. Pins 38 pass through the ears and furcations so as to pivotally connect the links. The shaft section'32 is furcated at 39 to receive one of the ears 36 and a pin 10 pivotally connects said ear with the section 32. The shaft section 18 is furcated at 41 to receive an ear of the adjacent link 8d and a pin 42 pivotally connects said link with the section 18. The furcations at opposite ends of the link 35 lie in planes at a right angle to each other and likewise the ears at opposite ends of the links 3 1: lie in planes at a right angle to one another. The pivots at opposite ends of the links are at right angles to each other and the links and their pivots thus constitute a universal joint connecting the shaft sections 18, 32. This enables the lamp 19 to be turned about an axis positioned substantially at right angles to the axis of the shaft section 32 that extends through the vehicle body.

It is readily understood that to swing the lamp '19 on its axis, the operator will turn the member 33 to rotate the shaft section 32. lVhen he does this the lamp will be caused to tilt slightly by reason of the bent section 18 which, in effect, constitutes a cam. The lamp may be tilted up and down, for a more or less permanent adjustment, by loosening the bolt 15 and moving the bracket section 14 into the desired relation with respect to the section 13. The bolt 15 will then be tightened. Thus the lamp may be adjusted to project its light at the proper angle in relation to a horizontal plane to conform with the traffic laws, when the lamp is positioned to direct its light forward; and when the lamp is turned to one side or the other the bent shaft section 18 will cause the lamp to tilt upwardly so as to project the light rays to a higher level than when the light is projected forward.

Now referring to Figures 6 to 11 inclusive, the bracket 12 is secured at one end to a face plate 43 adapted to fit against the outer face of the vehicle body. -The face plate l3 is provided near its upper and lower ends with holes at, 45, through which pass bushings 46, 47, respectively. The bushings 1-6, 47, are provided at their outer ends with heads 48 to engage the outer face of the plate 43, and are provided at their inner ends with screw-threads to receive tubular nuts 49 whereby the bushings are held securely in place. The bushings and nuts fasten the face plate 43 in position. The leads-20 pass through the upper bushing 46 to the interior of the car where they may be plugged into the lighting circuit in the usual manner.

The lower bushing a7 constitutes a bearing for a shaft section 50 which is provided 1 ,asmao at its inner end with an operating member 51 in the form of a crank. The outer end of the shaft 50 is provided with a socket 52 to receive one end of a flexible shaft section 53, which has its other end inserted in a socket 5 f secured to the lower end of the shaft section 18. In this instance the flexible shaft section 53 is formed by a spring wire helix.

It will be clear from the foregoing that to turn the lamp 19, in Figures 6 and 7, the operator will manipulate the member 51 to cause rotation of the shaft section 50. The results will be the same as produced when operating the member 33 in Figure 2.

In both forms of the invention the leads 20 are preferably secured by a clip 55 to the shaft section 18 so that only that portion of the cable extending between the clip and the lamp 19 will move when the lamp is swung on its pivot or shaft.

We claim:

1. In a lamp mounting, the combination of a face plate, means to secure the face plate to the body of a vehicle, a bracket projecting rom the face plate, a shaft section rotatably mounted on the bracket, a lamp carried by the shaft section, a bushing having a head at one end and screwthreaded at its other end, a hollow nut engaging the screw-threads, a shaft section extending t'hroughthe bushing, and a flexible shaft section connecting the other shaft sections. 1
