IMPROVED APPARATUS FOR CARBURETING AIR.

Specification forming part of Letters Patent No. 50,491, dated October 17, 1865.

To all whom it may concern:

Be it known that I, ERASMUSALLINGTON POND, ofltutland, in the county of Rutland and State ofVer|uont,l1avein 'entedcertain new and useful Improvementsin Gas-Machines, or Apparatuses for Generating [lluminatng-Gas by Charging Atmospheric Air with the Vapor of Hydrocarbon Fluids; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings.

The invention subject of this patent is based upon the principle which I have discovered, that it air be compressed or condensed and in such compressed orcondensedform allowed to enter a liquid of a volatile nature, such as the hydrocarbon fluids, it will suddenly expand and by such expansion absorb oremhody the vapors of said fluid and become charged or saturated therewith. It, therefore, air be forced through a tube contracted at its extremity which is submerged in benzine or other hydrocarbon fluid, it will, on issuing at the contracted end of the tube, expand, and in that condition become charged with the vapor of the fluid. Air charged in this manner with the apor of hydrocarbon fluids produces a gas answering the best conditions for illuminating and heating purposes.

From the statement of the principle of this my invention, it will be understood that there are numerous ways in which it may be carried into eflect, and that various simple yet efficient machines involving the same principle may be made at but little cost of construction and almost without liability of getting out of working order.

In the. following description of my invention I shall confine myself to such machines or apparatuses the operation of which I have experimentally tested, and which proved successful.

The simplest form of apparatus and most readily tested is represented in sectional ele-' burner, 41, is similarly secured or packed. "When.

the bottle is closed by the stopper the end of the tube B will be submerged in the liquid while the burner 12 will be on the outside ot'the bottle. If air be now blown through the tube D it will be. compressed in the tube in proportion directly to the blast and inversely to the opening at b of the submerged end ofthe tube but on issuing at the orifice I; the air will rapidly expand and charge itself with the vapor of theliquid, bubble. up through the liquid and collect in the upper part ofthe bottle, whence it escapes or is forced out through the tube D and burner d, where it may be ignited.

Better results may bcobtained by-using for the injection-tube one the extremity of which is bent, as shown in Fig. 6, and which should be inserted in the bottle so that the jet shall be directed upward through thcliquid. Similar results are obtained by a tube shown in Fig. 7, which, instead of being drawn into a small circular opening-thatis to say, bygradually diminishing its diameteris flattened at its extremity so that the terminal opening shall be capillary, or so narrow as to produce the desired degree of compression of the air before issuing from the tube. By a tube thus constructed, however, a larger amount of air may be forced through a given-sized tube.

In Figs. 8, 9, and 10, moditioationsin the construction of the tube or method of contracting the same are shown and indicated.

In Fig. 8 the tube, instead of being contracted at the submerged end, is closed by means of a plug of rattan or other reed-like wood in which the cellules form small tubes through which the air is forced by the action of the air-pump. The air will issue through these tubular cells or pores of the wood in line streams, each ot'which will expand and charge itself with vapor, as before described. 1n Fig. 9 the tube is closed by means of aporous mineral substance, and in Fig. 10 a number of small capillary tubes are cemented into the endoftheair supplytubeB. Smallcontracted tubes may branch from the main tube at thesides as well as at the ends.

I and, if desired, tested.

Obviousmodifications would be made in the construction of the apparatus if designed for practical use or as a permanent machine.

In Figs. 1,2, 3, and 4 I have shown such gas-m achines. Fig. 1 represents a vertical sec tion of a machine consisting of a fluid-vessel, A, from the bottom of which rises the end of the air-supply pipe B. This pipe is connected with an air-pump, blast-wheel, or other airforcing apparatus, operated by spring-power mechanism, weight, or otherwise. It may be coiled, as shown in Fi 1, or simply bent upward, so as to discharge the air into and through the mass of fluid contained in the vesset. The opening ofthe pipemay be contracted as shown in Figs. 5, 6, 7, 8. 9, or 10, or, as shown in this instance, it may be closed by a cluster of small tubes, 0. The air forced through these small tubes is charged with vapor and collectedin the upper part of the vessel and forced into and through the pipe D, which may be provided with a suitable burner, d, or supply other :pipes leading to burners. Fig. 2 represents a modification, whereby the air is more perfectly diffused through the mass of fluid. The air-supply pipe iuthis instance terminates in two contracted branch tubes, T, which support two concentric horizontal annular pipes, 1*,(see Fig. 3,) which are perforated with numerous small holes through which the compressed air finally escapes in fine streams but diffused through the mass of fluid. More or less such annular pipes may be used, according to the amount of gas desired to be produced. In Fig. 4 the airsupply pipe is shown provided with a wire-gauze or perforated plate partition, W, the etfectot which is to divide the column of air into fine streams, to-

more thoroughly pervade the liquid.

Having thus fully described my invention, and the manner in' which the same is or may be carried into effect, what-I claim is- 1. The method herein described of charging atmospheric air with the vapor of hydrocarbon fluids by the discharging the air through contracted openings into the mass of fluid, substantially as herein shown and described.

2. The method herein described of charging atmospheric air with the vapor of hydrocarbon fluids by dividing the column of air and discharging the same into the. liquid in small streams, substantially as hereinbefore described and shown.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.
