METHOD 0F AND APPARATUSv FOR CARBURETING AND MIXING GAS AND AIR.

SPECIFICATION forming part of Letters Patent No. 349,211, dated September 14, 1886.

Application filed January 25, 1886. Serial No. 189,662.

To @ZZ whom it may concern.-

Be it known that I, GEORGE Bosco COT- TRELL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Method of and Apparatus for Oarbureting and Mixing Gas and Air, of which the following is a specication, reference being had to the accompanying drawing.

My invention is an improved method of and apparatus for carbureting and mixing gas and air; and it consists, first, in heating the gas and conveying it to a carbureting-chamber containing crystallized naphthaline, and thereby enriching the gas;second,introducingamix ture of oxyhydrocarbon gas and atmospheric air into the carbureting-` chamber with the heated enriched gas; third, condensing the mixture of enriched carbureted gas and oxyhydrocarbon gas andk air, and, fourth, purifying the same preparatory to introducing it to the service-pipes.

My invention further consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, a-nd particularly pointed out in the claims.

The object of my invention is to provide a method of and apparatus for carburcting fixed illuminating-gas, and submitting it to any desired pressure, and thereby cause it to yield a light of uniform and any desired candle-power.

The accompanying drawing is a vertical longitudinal central sectional view of an apparatus embodying my invention.

A represents a carbnreting-chamber, which is preferably made cylindrical in form, having its upper end forming the section of a cone and communicating with a purifying-chamber, B,which forms a cylinder of reduced diameter. Surrounding theinclined sides of the upper portion of the carburetin gchamber is a waterjacket, C.

D represents the usual gas-meter-such as supplied by the gas companies in cities that are illuminated by gas-from which extends a pipe, E, having a series of branch pipes, F. Coils F are formed in the lower ends of these `branch pipes below the bottomof the carbureting-chamber, and the upper ends of the said pipes are provided with downwardly-extending discharge-pipes, F2. The pipe G leads (No model.)

from one side of the carbureting-chamber to a mixing-machine, H. This mixing-machine is divided into two compartments, h and h, which are lled to any desired depth with water. The pipe G leads to the compartment 7L, which is only about one-third as large as the compartment 7L', and the latter has an inlet-pipe, I, for supplying atmospheric air. In the compartment h is journaled a horizontal rotating screw or pump, K, and in the compartment h is journaled a similar pump or screw, L, which has about three times the capacity of the pump K. Any other preferred form of pump may be substituted for those hereinbefore shown and described, and the water may be omitted from the compartments h and h', as these are particulars which are not essential to the operation of my invention.

From the compartment h extends the pipe M, and from the compartment It extends a pipe, N, of about three times the capacity of the pipe M. These pipes M and N lead to a mixing-chamber or union pipe, O, the capacity of which is a little more than equal to the combined capacity of the pipes M and N.

P represents a pipe which extendshfroln the mixing-chamber or union pipe O into the carbureting-chamher, and the inner end of the said pipe P is turned downwardly in the center of the carbureting-chamber. A stop-cock, P', is located in the pipe P, and from the said pipe depends a branch pipe, R,'the lower end of which is bent at right angles and extends horizontally under the horizontal branch of the pipe E, and at a suitable distance below the same and below the coils F. A series of burners, R', are provided for the horizontal branch of the pipe It. From the union pipe O extends a second pipe, S, which leads to any desired portion of the building, and is provided with burners S', (one or more,) which are used for heating or culinary purposes.

In order to rotate the screw-pumps K and and L, I connect them by suitable gearing with a shaft, T, which has the pinion T. A gearwheel, U, meshes with the pinion T', which gear-wheel and pinion are located between the compartments h and h', and on the upper side of the mixing-machine is journaled a shaft,V, having a pinion, Y', that meshes with the gearwheel U. {To the outer end of the shaftV is attached a drum, XV. A crank, XV', is also provided for the shaft V, by means of which the latter may be rotated by hand. A cord, X, is coiled on the drum XV and passes over a pulley, Y, and to the free end of the cord is attached a Weight, Z. It Will be readily understood that as the Weight descends, the shaft V will berotated, and thereby cause the screwpumps K and L, which are geared to the said 1o shaft, to rotate.

I do not desire to limitmyself to the Weight, cord, and drum for rotating the screw-pumps, as these arey merely shown for convenience in illustration, and any preferred motor may be employed for actuating the pumps.

The earbureting-ehamber is partly filled to any required depth with crystallized naphthaline, and the purifying-chamber B is filled with excelsior, and any suitable purifying 2o chemicals-such as lime, or chloride of calcium oramixture of these and charcoal. The gas from the meter passes through the pipe l1] to the coils F, and is heated by the flames from the burners R', and forced through the 2 5 pipes F into the carbureting-chamber, Where it is enriched or carbureted by the crystallized naphthaline. This enriched gas is too rich to burn, and a portion of it passes through the pipe G; into the compartment h, and from 3o thence is forced by the pump li through the pipe Minto the mixing-chamber or union pipe O. Atmospheric air is sucked into the compartmcnt h.' by the pump L, and forced through the pipe N into t-he mixing-chamber or union pipe O, Where it mixes with the gas in the proportion of about three parts to one of the latter, forming a blue gas, which is suitable for heating and cooking purposes, but not for illuminating purposes. A portion of this blue gas is supplied to the burners R for heating the coils F', and a portion also passes through the pipe S to the burners S. The mixture of oxyhydrocarbon gas and air is supplied through the pipe P to the center of the carburetingchamber, and there discharged upon the heated carbureted gas therein, which causes the said gases to mingle and expand against the sides ofthe carbuietingchamber, where the heavier hydrocarbons are condensed by the waterjacket for the purpose of removing carbonaceous particles that would cause the gas to smoke when burned. From the carburetingchamber the gas passes upward through the purifyingchamber B to the service-pipe a., by which it is conducted to the burners for illuminating purposes.

A gas-gage, b, is provided for the carbureting-ehamber, and a stop-cock, c, is provided for the horizontal branch of the pipe R, the said stop-cock being connected with the gasgage by a rod, d. Gas is thus admitted to the burners R in a quantity proportioned to the degree of pressure in the carbureting-chamber, by which means the gas therein is maintained at a uniform pressure and supplied to the service-pipe, and thereby caused to yield a steady and uniform light. By regulating the quantity of gas and air supplied to the carburetingchamber an illuminating-gas of any desired candle-power may be supplied to the burners.

The mixture of oxyhydroearbon gas and air in the proportions specified forms a heatinggas which is very cheap and serviceable.

Crystallized naphthaline is a residue o1' coaltar or crude petroleum, solid in form, and volatile at 115 Fahrenheit.

By oxyhydrocarbon gas I mean the mixture of ordinary carbureted hydrogen, Vapor, and oxygen of the atmosphere, or, in other words, gas after having been enriched or carburcted in the chamber containing hydrocarbon-such as naphthaline-aud then mixed with oxygen or air.

A branch pipe, E, connects the pipe E at the upper end of the meter with the servicepipc a at the upper end of the carburetor. This pipe E has a valve, c', and the pipe E has a valve, c. 3y closing the valve c and opening the valve c the gas may be conducted directly from the meter to the service-pipe without passing into the carburetor or mixing machine.

Having thus described my invention, I claim- 1.
