IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 59,446, dated November 6, 1866.

To all whom it may concern:

Be it known that I, FRANCIS S. PEAsE, of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Oarbureters; and I do hereby declare the following to be a full, clear, and exact description of the same, suflicient to enable one skilled in the art to which the invention appertains to make use of it, reference being bad to the accompanying drawings, which form a part of this specification, and in WhlOl1 Figure 1 is a vertical central section. Fig. 2 is a vertical central section of a modified form of air-pump. Fig. 3 is a vertical central section of a modified form of deflector in the carbureting-chamber.

This improvement is adapted for positions and conditions where it is not convenient to obtain a blast of air through the carbureter, by the constant movement of machinery; and it consists inthe provision, in connection with a carbnreting-chamber and hydrocarbon reservoir, of a strong chamber, to be filled with compressed air, and the air-pump may be a permanent fixture upon it, or the air is forced into the cylinder by stationary machinery. It is particularly adapted for locomotive headlight, railroad and street cars, and coaches, dwellings, and light-houses.

In the drawings, A is an air-pump for the condensation of air into the chamber B. It passes thence by the pipe 0 to the rose D in the carbureting-chamber E, ascending into the deflector F, which is an inverted vessel with notches on its lower edge. As the entering air fills the deflector it issues from thence at the orifices made by the serrations in the edge thereof, and ascends through the perforated or reticulated plate G, which serves to mix the passing air and gas, and render it more homogeneous in quality. The diaphragm G also prevents the swashing of the liquid when the carbureter is placed upon a body in motion, as upon a locomotive, or street-car, &c. The gas passes from the generator, by the pipe H,

to the burner, which is represented in Fig. 1 as ahead-light with a reflector. The hydrocarbon fluid, which may be gasoline or any sufliciently light and vaporizable hydrocarbon, is supplied to the generator by the pipe I from the reservoir J, which is filled by the opening K.

The carbureting-chambers shown in Figs. 1 and 3 are substantially similar, the difference being mainly in the form of the deflector. In each case the bottom of the chamber is dishing, With'the rose in the center.

The air-pump shown in Fig. 1 is the ordinary single-acting pump, with a valve in the plunger, and one in the bottom of the cylinder, each opening downward, and the communication with the compressed-air reservoir is maintained or intercepted by the stop-cock L.

In Fig. 2 a modified form of air-pump is shown, in which water is used as a packing above the diaphragm M, the piston elevating a body of air at each upward stroke, which passes through the small openings in the diaphragm M, and up through the Water lying thereon, the valves closing upon the diaphragm when the pressure below is removed. By this means the air is prevented from returning, as the water forms a joint upon the valves on the diaphragm, and the parts are not obliged to be air-tight. The piston-head may be covered similarly with a small quantity of water.

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

The combination, with a carburetingchamber, of a strong reservoir, for containing a supply of compressed air, substantially as and for the purpose described.

2. The mode of operating the air-pump with a waterpacking above the valve or valves, substantially as described.

FRANCIS S. PEASE.
