SPECIFIQATION forming part of Letters Patent No. 475,242, dated May 17, 1892.

Application filed J' 11118 1891. Serial No. 396.400- (No model.)

To a, whom it may concern.-

Be it known that I, LANCE L. J OBLING, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, 5 have invented certain new and useful Improvements in Locomotive Head-Lights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to [0 which it appertains to make and use the same. My invention has for its object to improve locomotive head-lights by so constructing the reservoir and burner and mounting the same that they may be easily removed from and .15 connected with the reflector without moving the latter; and it consists of a reservoir for the head-light having certain features of novelty and in various improvements in the apparatus as a whole, all of which will be hereinafter pointed out.

In the drawings, Figure 1 is a rear elevation of a head-light apparatus embodying my invention, one-half of the oil-reservoir being in central longitudinal section. Fig. 2 is'a side view of the apparatus, and Fig. 3 is a rear elevation of the reservoir and its supports detached.

In the drawings, R designates the reflector,

which may be of the usual parabolic shape. It is supported upon the slide-board O at its front edge by the bracket P.

u and y designate, respectively, the screws by which the bracket P is secured to the slideboard and to the reflector, and 10 indicates the 3 5 air-hole through the board.

0 6 represent standards rising from the board 0 in rear of the reflector and having their upper ends formed into semicircular bearings 0 for the oil-reservoir a. 4

o circular in cross-section and is supported by the standards, being held in the bearings 0 thereof by the semicircular bands d, which are secured to the standards by the screws 6 e.

B is a boss extending rearward from the central portion of the reflector and being adaptedto rest in the hearing I) on the top of the reservoir a, where it is held by the cap H, which is connected with the hearing by the screws 8. This construction of parts gives to the reflector a support at its rear and also se- This reservoir is cures the reservoir from turning in its sup ports. A holder K for the lamp-chimney O is carried by the cap H.

h is the oil-feed pipe leading from the resv ervoir to the burner I, this tube being straight and thus much less liable to clog than is the common form of feed-pipe, which is made with an elbow.

The reservoir a is divided by a'number of transverse partitions p, which are perforated in their lower portions at n for the free passage of the oil from one part of the reservoir to another. These partitions serve as braces to strengthen the reservoir and also prevent the oil from rushing from end to end thereof 6; as the locomotive sways, which violent movements of the oil seriously interfere with its proper feed to the burner, particularly when the oil is low in the reservoir, and thus causing the light to flicker or go out. Y v

1' represents the filling-opening to the reservoir, and 'v the air-vent.

There are several advantages, besides those which have been referred to, incident to a reservoir constructed and arranged as I have shown and described. As now ordinarily constructed the reservoirs for locomotive headlights are curved, following more or less nearly the outside contour of the reflector. This makes it difficult to get at the burner to clean it and to regulate the light. I, however, make the reservoir straight and mount it in rear of the reflector, so that it in no wise interferes with free access to the burner, which may be manipulated easily, as circumstances may require.

WVhen it is desired to remove the reservoir and burner, it is only necessary to takeoff the cap H and chimney-holder K and the bands cl and to remove the chimney 0, when reservoir 0 may be slipped from its support, it being en tirely unnecessary to move the reflector to permit this.

Without limiting myself to the precise construction and arrangement of parts shown, 5 what I claim is- 1. In a head-light apparatus, the combination of the lamp or burner, the reflector, the straight reservoir circular in cross-section, detachably mounted in rear of the reflector, and

means for securing the reservoir from turncircling bearings for the reservoir, from which [0 ing in its supports, substantially as set forth. it may beremoved at pleasure by removing 2.
