TO ALL WHOM IT MAY CONCERN:

Be it known that I, FRANCIS S. PEASE, of Bufl'alo,'Erie county, New York-, have'inventcda new and useful Improvement in Carburetters for Head-Lights for Locomotives and I hereby declare thefollowing to be a full, clear,-and exact description thereof, reference being had to the accompanying drawings, making part of this specification. i

The object of the invention is efiiciency, economy of material and space, and the avoidanceof long connecting pipes. The carburetting apparatus is all contained within the, shell of the head-light, the space around and in the rear of the reflector being occupied by the'spring or equivalent power, the blower, the carburetting-chii nber, and the connectihg pipes. In the drawings- Figure 1 is an elevation, with a portion of the side and of the-reflector removed.

Figure 2 is a modification of the blower.

A is the shell and B the reflector of the head-light of a locomotive. C isa barrel contai'nin'ga spring, which, when wound up, revolves the wheel D, whose motion, by band, gearing, or friction, is communicated to the wheel E on the shaft M, whose tripping-cams lift the bellows F and discharge the air therein contained into the airreservoir G, whence it is conducted by a pipe, H, to the carbnretting-chamber J, whence it is passed through or over a body of gasoline or other hydrocarbon fluid, and in company withtho hydrocarbon vapor is conducted to the burner I in the reflector B.

I do not herein claim any particular form of bellows or blower, or any special arrangement of carburetterchamber in which the air is brought into contact with the hydrocarbon liquid. Fig. 2shows a revolving blower driving the air to the carburetting-chamber J. In this case the blower-shaft is rotated, as in the fig. 1, by a spring or equivalent device. An arrangement of a weight may be applied to rotate the cam-shaft M, or the blower-shaft, fig. 2, but I prefer thespring, owing to'its compactness and efficiency. The blower may consist of one or more bellows, or of a suction or force-fan, or any other air-forcing arrangement. The evaporating action of the carburettor-within the head-light case keeps the entire lamp cool, and preserves the silvering of the reflector from injury by heating. A great advantage of my invention is that it furnishes a complete and eflicient lantern, includingthe carburetting apparatus, the whole being attachable to or detachable from the locomotive at will, and as independent of the locomotive in its action as head-lights of the old construction, in.

which common eil-lamps are used. As the apparatus does not depend on the locomotive for the power to work it, it will act as well while the locomotive is at rest and when steam is down. This feature is of great importance in case of accident and under many other circumstances. I do not claim broadly the u e of carburetted air for the head-lights of locomotives.

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

1. The combination of a carburetter with the head-light of a locomotive when the former is placed within the shell of thehead-light, substantiallyas described. 7 I

2. I claim the combination of the spring, the blast apparatus, one or more, and the carburettor, arranged in the shell of a head-light.. l l 3. I also claim an argand burner and a carburettor arranged within the head-light of a locomotive.

To the above specification of my improvement I have signed my hand this 19th day of arch, 1867.
