APPARATUS FOR CARBURETING AIR OR GASES.

SPECIFICATION forming part of Letters Patent No. 308,886, dated December 9, 1884.

Application tiled Jtly 10, 1884. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW J. ENGLISH, a citizen of the United States, residing at Oincinnati, Ohio, have invented new and useful Improvements in Apparatus for Carbureting Air or Gases for Illuminating Purposes, of which the following is a specification.

My invention relates to that class of gasmachines in which atmospheric air or gas is forced through suitably-arranged carburetingchambers in contact with a volatile hydrocarbon liquid,with a view to the saturation of the gas with the hydrocarbon vapors, to be used for domestic, industrial, or illuminating purposes, and it consists, first, in the conautomatic supply of liquid to the carburetingchambers as needed, and, second, in the provision and arrangement of means for indicating the exhaustion of liquid from the supply 19 p, the inflow and outflow air pipes; It, the

reservoir; 1), the overflow-pipes between the carbureting-chambers, these parts beingconstrueted and arranged in the usual manner, and the chambers being channeled and provided with absorbent material (not shown in the drawing) to assist evaporation.

3 5 To secure the automatic feeding of the chambers c"a a, I place in the bottom B of the reservoir R a valveseat and opening, 0, controlled by a lift-valve, o, the latter connected by rods r r and a pivoted connecting-lever, Z,

with a float, f, arranged in the lower carbureting-chamber, a. The lever Z is mounted upon a suitable supporting-frame, c, or it may be hung from top of the reservoir It, and the rod 1' is carried down through an open tube, t,

i 5 passing from a point above the highest level of the liquid in the reservoir B into the lower chamber, a, through the separating-partitions. The construction is clearly shown in the drawing, and the float f should be of sufficient Weight to elevate the valve with certainty.

struction and arrangement of means for the against any tendency of the latter to stick from any cause, yet to rise with the liquid and close the valve when the proper level is attained.

It will be apparent that as the greatest consumption of liquid takes place in the lower chamber,where the air or gas is first admitted, and as the chambers are furnished with overflow-pipes,the feeding will take place continuously as long as any liquid remains in the upper chamber, R-that is, a very slight diminution of liquid in the lower chamber, a,will allow the floatf to fall, which, acting by its weight on the rod 9 and lever Z, will lift the valve 1; from its seat, allowing the liquid to flow into chamber a thence, when the top of the overllowpipe 1) is reached, into the chamber a, and similarly, by pipe 133 therein, into the chamber a, where equilibrium will be es" tablished by the raising of the float f and con- '70 sequent closing of valve t. It will thus be seen that as a slight lowering of liquid in chamber a is accompanied bya lesser lowering in chamber a, and one still less in chamber a, the quantities of liquid contained in 7 5 the several chambers will bear a constant relation to each othersuch that as long as any liquid remains in the upper chamber the valve 1) will deliver it continuously and in just the 7 quantity required for consumption. 30

To determine when the chamber R becomes nearly empty, I provide a tube, t, (through which rod 1-", carrying the float f, passes,) and which also passes through the horizontal partitions b of the carbureting-chambers a a a 8 5 and, furnishing communication between the top of the upper reservoir, R, and the top of the lower chamber, a, acting also as a vent and allowing ready escape of liquid through valve '0 by equalizing pressure. Two test- 0 pipes, w 20 are also provided, issuing from the side of reservoir R, near the bottom, but at different heights, and provided with whistles or similar devices, 5/, at their upper ends, and closed by capscrews. Upon unscrewing 5 the cap a from tube w, should the level of liquid in reservoir B have fallen below the opening 8, the air or gas entering at p in lower 7 chamber, a, will pass by means of pipe 25 to the reservoir R, and thence out through pipe 10, giving warning by blowing the whistle g. A similar test may be made with the pipe 10 which will in turn indicate the fact, should the level of liquid in R be below the orifice s, when the reservoir R will be empty.

A supply-pipe, S, furnishes the means of filling the empty reservoir, and may also serve as a test-pipe, when provided at the top with lateral branch pipe and whistle 9, closed ordinarily by a cap. If the reservoir be empty, on unscrewing the cap the whistle sounds. The vent-pipe gallows air to escape while filling the reservoir.

To provide for the escape of water condenschamber a, oil-supply reservoir R, and test ing in the gas or'air supply pipe 1), I provide in the latter an outlet-pipe, p, with a cock, K, and a small collecting-chamber, O, at or near the entrance to the chamber a, commu nicating with the open air. On opening the cock at intervals any moisture will be eX- pellcd.

I claim as my invention and desire to secure by Letters Patent of the United States 1. In'agas-carburcfing machine embodying a reservoir arranged above a series of carbureting chambers, the latter provided with short overflow-pipes connecting the chambers, the lower chamber being the air or gas entry, the float f in the lower chamber, the rod 0, connecting the float and a lever, Z, through the open tube 1;, (said lever being pivoted to said rod,) the lever l carrying pivoted at one end the float-rod 1- and at the other end the valve-actuating rod r, and being pivotally supported at an intermediate point in the oil-- fixed to the conical valve 1), seated in the bottom of the reservoir, and surrounded by suitable protecting netting, the open tube 25, furnishing free air or gas communication between the lower chamber, a", and the oil supply chamber It, and surrounding the float-rod 1"", the whole combined, arranged, and operating as and for the purpose specified.

2. In a carburetor having an oil-reservoir above a series of carbureting-chambers con nected in series, a pipe, t, surrounding the float-rod T and providing air communication between the oil-reservoir and lower air-entry chamber, in combination with the ainentry tubes 20 w (one or more,) having attached above whistles or call-indicators {1, actuated by the passage of gas outward therein, said tubes entering the lower chamber at different heights, substantially as described.

3. In a carburetor having an oil-reservoir above a series of carburetirig-chambers connected in series, and with tube t, connecting the top of oil-reservoir and lower air-entry chamber, the combination of oil-reservoir It, tube 16, air-entry chamber (1., air-pipe p, and the enlarged chamber at or near the air-entry point on the air sup fly-pipe provided with outlet'pipe p, stop-cock l1", and a manipulating-handle extending upward, arranged and o1i erating substantial] y as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing wit- DQSSGS.

ANDREW J. ENGLISH.
