Application filed October 16, 1918.

To all whom it may concern:

Be it known that 1, CHARLES D. RYDER, a citizen of the United States, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Tractorlaamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

The object of my invention is to provide a lamp for motor tractors which shall furnish in a single unit a head light for the tractor to illuminate the soil to be cultivated and at the same time shall illuminate fully the implement operated by the tractor.

My object is to furnish a solid substantial tractor lamp which shall be adapted to effectively withstand the strains to which tractors are ordinarily subjected and in which the lamp structure shall be so mounted that the lights can be projected in any direction desired. A further object of my invention is to provide a construction in which one of the lamps can be readily and easily detached to be used as a trouble lamp for any part of the implement.

it may be of vital importance at certaln seasons of the year that the farmer should be able to utilize his tractor at night and not be required to stop his work with the coming of darkness. It is therefore of great importance that he may be able to illuminate the field ahead and also the implement in the rear, To furnish a lamp to withstand the rough usage and vibration of the tractor and which shall furnish light in both directions, is the essential object ofniy invention.

The invention consists of that novel construction and arrangement of parts to be hereinafter particularly pointed out and claimed by which the above objects are attained.

in the drawing, I

Figure 1 is a front elevation of my 1111- proved lamp.

Fig. 2 is a central vertical section.

Fig. 3 is a detail section of the clamp for securing the lamp to the standard.

Fig. d is a perspective view showing the auxiliary lamp detached for use as a trouble lamp.

Specification of Letters Patent.

Patented Aug. 9, 1921.

Eerial No. 258,381.

F or mounting the lamp on the tractor to prov de a solid and substantial support, I provide the hollow post or standard 1, which is secured by a set screw 2 in the collar 3 pro ecting from the bracket plate 4, which is securely bolted or riveted to a convenient portion of the framework of the tractor. The post or standard 1 is held by the set screw so that upon releasing the set screw the post may be rotated on a vertical axis as desired.

The main casing of the lamp proper, circular in shape, is illustrated at 5, provided with the reflector 6, and a glass front 7 which is held in any convenient way between the rim 8 and the casing, while 9 is the usual electric lamp bulb, with socket piece 10 to fit in the central opening in the reflector. The casing is so shaped that there is considerable space 11 left between the back of the reflector and the casing, and an opening is out, preferably circular and preferably in thelowei' portion of the casing in which is titted an auxiliary casing 12. This auxiliary casing is preferably formed in a separate piece and clamped by the flange 13 to the main casing, or it may be riveted thereto or otherwise secured, or the two casings may be made in a single piece. This casing is provided with a. hinged removable door li. The hinge 15 is preferably of the ordinary hasp type, but is provided with a removable pintle 16, which can be readily removed to release the hinge. In order that the pintle may not be lost, I prefer to secure the pintle to the main casing by a fleaible cord or chain 1?. The opposite side of the door 14: is formed with a spring clip 18 to cooperate with a spring plate 19 to clamp this side of the door to the outer inturned edge 20 of the casing 12. The door portion is provided with a glass cover 21, and the reflector 22 is secured to the door portion. The reflector is provided with the electric lamp bulb 23, the socket 2 1 of which is seated in the central opening in the reflector. The electric light cord 25 for furnishing the electric light to the lamp bulb 23 is of considerable length, say ten, fifteen or twenty feet, and this cord is folded away in the space 11 between the main casing and the reflector of the headlight, and is united with the cord 26 from the lamp 9 and passes out through the casing at 27 and into the hollow standard 1 down through the standard to the battery or other source of current.

Secured to the main casing on the outside, is a plate 28 carrying a projecting short arm or short rod 29, which is inserted in an opening in the upperportion of the standard. To secure the arm 29 to the standard, I provide the bolt 30 with the eye 31, through which the arm 29 is passed, and this bolt 80 projects through an opening in the top of the standard, provided with a thumb nut 32. By tightening up the thumb nut the arm is clamped between the eye and the standard opening so as to be held rigidly in place, while by loosening the thumb nut 32 the arm and lamp can be rotated on a horizontal axis. Thus with the rotation of the lamp on a horizontal axis and the rotation of the standard or post on a vertical axis, I will have a universal movement for the lamp, so that the light from the lamp bulbs 9 and 23 can be projected in any direction desired, the reflector 22 throwing the light rearwardly and downwardly from the direction the rays of light are thrown. by the main reflector 6.

lVi-th this construction a most durable and effective means is provided for supplying light for tractors, in which the headlight can be utilized for illuminating the field to be cultivated and the rear light for illuminating the implement. Should the operator desire a trouble lamp for the close examination of some special part of the machine or tractor mechanism, by removing the pintle 16, the smaller lamp can be detached from the casing, and by reason of the length of the cord can be carried to any point desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In combination with a standard and lamp casing mounted thereon, with an electric lamp bulb mounted in the casing, and a reflector for throwing light in one direction, the reflector and easing shaped to provide ample space intermedlate the two, of an auxiliary casing, with electric lamp bulb and reflector therefor, with the light conducting wires of considerable length and stored between the main casing and main reflector, and means for detaching the auxiliary lamp for use separately.

2. In combination with a standard and lamp casing mounted thereon, with lamp and reflector therefor for throwing the light in a forward direction, of an auxiliary casing, with lamp and reflector removably mounted in the auxiliary casing to throw the light in the opposite direction, and means for detaching the auxiliary lamp and its reflector for use separately and as a unit as a trouble lamp.

3. In a headlight for tractors, the combination of a lamp casing having a rod extending laterally therefrom, a socketed bracket on the tractor, a post slidable and rotatable in said bracket socket, a set screw or the like for clamping the post in position in the said socket, said post having a hollow portion at its upper end, means for journaling the lamp rod transversely of said hollow portion, and a socketed member engaging over the said lamp rod, and having a nut therein, said nut taking its hearing at the upper end of the post, whereby the screwing down of the nut will clamp the lamp rod in adjusted position in the post.
