HEADLIGHT.

SPECIFICATION forming part of Letters Patent No. 6t3,141, dated February 13, 1900.

Application filed January 31,1898. Serial No. 668,593. (No model) To (ZZZ whom it may concern.-

Be it known that I, JOHN KIRBY, J12, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in GasGenerating Headlights; 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 which it appertains to make and use the invention.

My invention relates to gas -generating headlights for use on locomotives, motorcars, steamboats, and in other places, and of which the following is a specification.

The object of my invention is to combine with a headlight-case an interior equipment consisting of a base, a reflector, a burner, a gas-generator,and a liquid-reservoir,whereby illuminating-gas is produced by the action of liquid on gas-producing material contained within the generator and to so combine the said features as that the gas may be produced and consumed within the case and whereby light will be reflected through a glass-covered opening in the case; also, to so combine the several features of said interior as that they shall comprisea single structure removable bodily from and replaceablein the case in a convenient and efficient manner.

The invention consists in certain novel features of construction, which will be hereinafter fully described, and pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a perspective view of alocomotive-headlight embodying my invention and having a portion of its case broken away and its door open to show the interior within. Fig. 2'is a rear perspective view of the interior removed from the case. Fig. 3 is a vertical section through a portion of the rear end of the reflector and the supporting-standard, showing the manner in which the former is connected with the latter; and Fig. 4, a plan view'of Fig. 2.

Similar letters and numerals of reference represent corresponding parts in all the figures of the drawings.

A represents the case, which may be provided with suitable air inlets and outlets to support and carry off the products of combustion and which may be constructed of any material suitable for such purpose and of proper size and form to receive the interior B, which consists, chiefly, of a parabolic refleetorO, gas generator and holder D, liquidreservoir E, supporting-Standard F, and sliding base G. The supporting-standard F is fixed to the said sliding base and extends up wardly therefrom, and it is provided with branching arms 1 and 2, one ofwhich carries the gas-generator and the other carrying the liquid-reservoir, and these arms are so formed as that the generator and the liquid-reservoir may be located at either side of the reflector to economize space, as more clearly shown in Fig. 4. The front or open end of the reflector is provided with a flange 3, and it is secured to the base G by means of a suitable connection 4, and its rear end is preferably secured to and carried by the supporting-Standard F by means of a stem at, having a flange 19 secured to the apex of the reflector, the said stem being adapted ,to engage a hole 0 through the standard and to be held therein by a screw (1, as more clearly shown in Fig. 3. The reflector is provided with upper and lower openings 5 and 6. Through the latter opening there extends one end of a gas-pipe I-I, carrying a burner I, the opposite end of said pipe being in communication with the interior of the gas-holder D. A chimney J may be carried by the burner and protrude through the opening 5 of the re flector to carry off the products of combustion. The front wall of the case is provided with an opening of about the diameter of the open end of the reflector, and surrounding this opening there is an outwardly-projecting rim 7, provided with an annular flange 8, the said rim carrying a glass disk K, which bears against said annular flange and through which disk light from the burner is reflected in the usual manner. The case is also provided with a door 9, having a suitable fastening 10, and it is mounted on a base L, provided with ways 11, which correspond with runners 12, forming part of the sliding base G, and Whereby the contents of the case can be readily removed bodily from and replaced in the case through the door 9. y

The preferred material from which the gas may be produced is carbid of calcium, and

this material is contained within the generator D, which also serves as a gas-holder and which is connected with the liquid-reservoir E by means of a pipe 13, Fig. 4, and through which pipe water orother suitable liquid carried in said reservoir may be supplied therefrom to the gas-producing material Within the generator and the supply thereof controlled by suitable regulating mechanism, which may be actuated by the pressure of gas within the generator produced by the action of the liquid on the gas-producing material.

I amaware that it is not new to mount the contents of a headlight-case on a removable base, which can be withdrawn therefrom, and that such construction is customary in the manufacture of oil burning headlights. Therefore I make no claim to such construction broadly, but the idea of manufacturing and utilizing gas within a headlight-case in the manner herein described is, I believe, new and novel and destined to be of great value in the art to which it appertains.

I therefore claim as my in vention 1. In a headlight, a case having a door and a glass-covered opening, in combination with an interior equipment consisting of a reflector, a gas-generator, a gas-holder located at one side of the center line of the reflector, a liquid-reservoir in open communication with said generator and located at the opposite side of the center line of said reflector, a gasburnerlocated in proper relation to the focal point of the reflector and centrally of said gas-holder and said liquid-reservoir, and a removable base, the Whole forming a single structure adapted to be inserted in and withdrawn bodily from the case, and whereby gas is produced and consumed within the case and the light utilized to illuminate the roadway in advance of the headlight, substantially as shown and described.

2. In a headlight, a case having a door and a glass-covered opening, in combination with an interior equipment consisting of a reflector, a gas-generator located at one side of the center line thereof, a liquid-reservoir in open communication with said generator and located at the opposite side of the center line of the reflector, agas-burner located in proper relation to the focal point of the reflector and centrally of said generator and said reservoir, and a removable base, the whole forming a single structure adapted to be inserted in and withdrawn from the case, substantially as shown and described.

3. In a headlight, a case having a door and a glass-covered opening, in combination with an interior equipment consisting of a removable base; a reflector; a standard projecting upwardly from said base; a gas-generator and a liquid-reservoir carried by said standard on opposite sides of the center line of the reflector; the said liquid-reservoir being in open communication with said generator, and a burner located in proper relation to the focal point of the reflector and centrally of said generator and reservoir, the whole forming a single structure adapted to be inserted in and withdrawn from the case, substantially as shown and described.

4. In a headlight, a case having a door and a glass-covered opening, in combination with an interior equipment consisting of a removable base; a reflector; a standard projecting upwardly from said base and supporting the rear end of the reflector; agas-generator and a liquid-reservoir carried by said standard on opposite sides of the center line of the reflector, the said liquid-reservoir being in open communication with said generator, and a burner located in proper relation to the focal point of the reflector and centrally of said genererator and reservoir, the whole forming a single structure adapted to be inserted in and withdrawn from the case, substantially as shown and described.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 29th day of January, 1898.

JOHN KIRBY, JR.
