IMPROVEMENT IN THE MANUFACTURE 0E CARBON-BLACK FROM NATURAL CARBURETED- HYDROGEN GAS.

.. Specification forming part of` Letters Patent No. 131,446, dated September 17,1872.

To all whom it may concern:

Be it `known that I, JOHN HOWARTH, of Salem, in the county of Essex and Commonwealth of Massachusetts, have made an invention of a new and useful Utilization of Natural Garbureted-Hydrogen Gas; and do hereby declare the following to be a full, clear, and exact description thereof, due reference being had to the accompanying drawing, which is a perspective view of an apparatus for carrying out my invention.

The purpose of this invention is to utilize the carbureted-hydrogen gas which escapes in considerable quantities from the tubular wells sunk in the earth in the attempt to obtain petroleum or hydrocarbon oil, this gas having been heretofore allowed to go to waste, the result of this utilization being a superior carbon-black.

In treating this gas for the purpose of carrying out my object I have employed as one method of so doing an apparatus constructed substantially as follows:

A in the accompanying drawing represents the upper portion of the tube of a tubular well, such as is sunk in many localities in prospecting for petroleum-oil, such tube being provided with a safety-valve, a, which permits the escape of gas when the pressure exerted by it upon the receiver isA too great. B represents a vessel composed of a suitable material, and containing a quantity of water or oil upon which a bell-float, O, is placed after the manner of ordinary gas-reservoirs, the well-tube A communicating with the interior of the vessel B by a suitable pipe, D. Extending from the receiver B to a suitable locality is a second pipe, E, which terminates in a horizontal extension upon which are placed a series of gas-burners, F F, &c., in such number as may be found desirable. Below each burner or each set of burners I dispose a curved apron or trough, G, from the bottom of which, one or more discharge pipes or ports, H H, extend, the outlet of each pipe being situated immediately over a movable box or receptacle, I, placed below them. In order to intercept the ame issuing from each burner, and collect the carbon resulting from the partial combustion thereof, I employ a slab or and sliding in horizontal grooves or ways a a formed in the lower part and on opposite sides of the-dome P.

In practice I prefer that a scraper should be provided for each pair of burners in 'order that a short movement of the handle or rod which connects them may suffice to scrape the entire under surface of the slab J.

The operation of this apparatus is as follows: The gas issuing from the'tube A under considerable pressure passes through the pipe D, and into the reservoir B, from whence it passes into the pipe E and burners F F, &c. The gate of each burner is opened and the gas inflamed, each flame being intercepted by the soap-stone slab J, which is situated immediately over them. The carbon, resulting from the imperfect combustion of the gas, is deposited upon theunder side of the slab J, from which it-is to be detached by the scrapers 0 O, Sto., and precipitated into the troughs G G, from whence it is delivered through the ports H H to the vessels I I, which are to be emptied into asuitablereceiver as often as is necessary. As a high temperature of the slab J would impair the color of the carbon-black deposited upon it, I dispose upon its upper surface a closed pan or vessel, I?, of wat-er, to reduce its temperature, such water being constantly renewed. Any quantity of carbon-black which escapes upward through the perforations of' the slab J will enter the chamber or dome K, and be deposited upon the cover of the panl? or other parts of the chamber. The safetyvalve a provides a means of disposing of such portion of the gas issuing from the well-tube as is not required at the burners.

I do not confine myself arbitrarily to the precise details of construction of the process 2 ISLA/L6 or apparatus herein given for carrying out the purpose of my invention, as these may manifestly be Varied to a considerable extent without changing the character of the result.

Claim.

I claim- The production of Carbon-black, from the natural oarbureted-hydrogen gas issuing from the earth7 by the process substantially as is herein described.

JOHN HOWARTH.
