IMPROVED APPARATUS FOR CARBURETING GAS.

Specification forming part of Letters Patent No. 56,503, dated July 17, 1866.

To all whom 1S/may concern.' h

Beit known that I, WILLIAM M. WRIGHT, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and improved apparatus for increasing the bulk as well as the illuminating property of the heavy carbureted hydrogen or oleiiant gas used to light our streets. This has been often attempted before by mauydifterent contrivances. Therefore I lay no claim to the principle, but to an improved apparatus by which these gases can be held as long as desired in contact with the vapor of hydrocarbon fluids while passing through the apparatus. Thus in a box twelve (l2) inches square the gas can be made to traverse a chamber one hundred and forty-four (144) inches, (or more, if required,) charged with hydrocarbon vapor. Being thus so long held in contact with the vapor it receives additional equivalents from it, so as not onlyincreases its volume, but greatly improves its illuminating power. I do hereby declare the following is a full, clear, and exact description of the construction and operation of my improvement, reference being had to the annexed drawings, making a part of this specification, in which- Figure A is an upright sectional view, showing the gas-chamber formed by the divisionplates. Fig. B is a transverse section. Figs. O and D are divisionplates; Fig. E, the box; Figs. F F, the gas-pipe attachments; Fig. H, opening for pouring in the hydrocarbon huid; Fig. K, glass gage; Fig. R, sectional View of fiat tube; Figs. l l l l l l, gas-chamber; Fig. N, iiat tube; Fig. 2, hydrocarbon Huid; Fig. 3, cloth covering on plates; Fig. 4, notches in division-plates; Fig. 5, opening in divisionplate D.

The box can be made of tin or galvanized iron, or their equivalents, and should be of such a size as to effect the work contemplated. A box one foot square is a convenient size, and when charged with one gallon of hydrocarbon :fluid of aproper kind will earburet from seven to ten thousand feet of gas, according to the quality of it.

The division-plates are made of the same material as the box, and are of two kinds. The plates O are notched above and below, Fig. 4. The plates D are notched below, Fig.

4, with two openings, Figs. 5 5, about onethird distance from the bottom. The size of these openings should correspond with the amount of gas to be passed through them. These plates are covered with woolen or cotton cloth, Figs. 3 3, leaving bare a half-inch on either side to permit the plates heilig soldered in the box.

In making the box one side should be left off, so that the division-plates can be inserted in the following manner: First, mark off equidistant lspaces on the sides of the box; then take a plate, O, and place it first in position and solder it fast-viz., the whole length of plate on both sides; then take a plate, D, and place it next in position, and solder the same as the other, including the upper end, thusalternating unt-il all are fixed in, ending with a plate, O. Now solder on the remaining side. The box should be tested as to its being gastight before being used. Now charge the box with the hydrocarbon iiuid to a point below the holes in the plate D, which can be best determined by the glass gage K. The box should be well shaken, so as to fully saturate the cloth. When it is attached for practical purposes its operation is as follows: The gas enters at the opening, Fig. F, and takes the course of the arrows in the drawing A, rising through the top of the box, passing through the notch, Fig. 4, of the plate O, then descends to the openings, Fig. 5, in theplateD, passing th rough them, and thus up and through the entire length of the chamber till it makes its exit at Fig. F into the ordinary pipes and fixtures, to be conducted to the points for using.

The amount of iinid in the box can be seen by examining the gage, Fig. K. It should be vreplenished when within one-half inch of the bottom. The gas is by the chamber held long in contact with the cloth saturated with hydrocarbon.

The broad flat tube, Fig. N, is made of two pieces of tin. The back plate, Fig. P, is oneeighth (gi) of an inch deeper than the front plate, T.

The edges o o o o are soldered their whole length. Into this flat tube is drawn a piece of flannel cloth of double thickness. I ts lower edge is seen at Fig. Y and the upper end at Fig. X, where it is turned over one inch as an apron on the front plate, T. This piece is held down by the small bar of tin W. This tlat tube can be placed at the side of the box, as seen in the drawing` A, or alongside of the division-plates; or,if desired, it could be made to take the place of the division-plates.

For a box twelve (l2) inches square I would recommend the use ot' t'our (4) of these tubes, placed at different parts of the box. I do not claim the principle ot capillary attraction.

The operation is as follows: The fluid is drawn u p through the tube by capillary att-raction from the lowest part ot' the box only, and enters the tube at Fig. Y and is discharged by the apron Z. This operation is constantly going` on, so that in twenty-four hours one gallon ot" hydrocarbon iiuid will change its rela tive position as to bottom, top, and middle positions. By the operation of this flat tube there is kept up a continual interchange of every drop of hydrocarbon fluid contained in the box within a given time, and this goes on until it is all consumed.

By the application of' this principle the last drop ot' the hydrocarbon is kept at the saine specific gravity as when it was put into the apparatus.

The hydrocarbon cannot become less volatile as it decreases in bulk by evaporation, but

will maintain its original volatility as long as any portion ot it remains, thus overcoming the `great difficulty experienced by experimenters, viz: that the ratio of decrease of Volatility in hydrocarbon fluids is in proportion to the decrease of bulk by evaporation.

I claiin- 1. The use of divisiomplates covered with cloth or its equivalent material, with their openings, notches, and adjustments inan in closed box, so as to form a continuous air-tight chamber when the lower part of the boX is charged with a iiuid, as and for the purpose described.

2. The use of the tlat tube, or its equivalent arrangement, for preventing the heavier portions ofthe iuid hydrocarbon from remaining at the bottom of the box, thereby securing` a uniform volatility from all the fluid till it is consumed, as and for the purpose described.

3. A combination of division-plates, openings, notches, cloth coverings, and hat tube in an inclosed boX, substantially as and for the purpose described.
