IMPROVEMENT IN BURNING HYDR QCARBONS.

Specification forming part of Letters PatentNo.,132,440, dated October 22, 1872.

To all whom it may concern:- i Be it known that we, J OSEPHUS CHANDLER and DAVID A. WRAY, both of Pioneer, in the county of Venango and State of Pennsylvania,

have invented a new anduseful Improvement in Burning Hydrocarbon s, of which the following is a specification: v

This invention relates to that class of apparatus intended for burningh-ydrocarbons for the production of heat of greater or less intensity in the various metallurgical operations of welding, brazing, heating, melting, deoxidizing, &c.; and it consists in the combination of a steam or air jet, or both, a supply-' pipe for the admission of hydrocarbon or'hydrocarbon vapors, a coil for superheating a second supply-pipe for the admission of hydro- I ondly, carbureting said fixed gas; and, thirdf,

ly, the function of a compound blow-pipe.

In the drawing .the figure represents our improved hydrocarbon-burner, portion thereof being in section the better to show the operation of our device.

A is the pipe for the passage of air or steam, provided with a stop-cock, a, and terminating in a jet or nozzle, J, said jet entering the enlargement of pipe F immediately beneath the delivery point of pipe B. B is a tube or pipe connecting with a hydrocarbon-reservoir, and provided with a stop-cock, I), for regulating the supply of air or hydrocarbon. This pipe delivers the hydrocarbon or. hydrocarbon va-.

, por into the enlarged portion of pipe F, from whence it is impelled forward into superheater 0 by the jet enteringv from f. The pipe'F. decreases slightly in diameter, and is coiled Q to form superheaterO. Thiscoil may be inclosed' within a fire-chamberseparate fromor" in the same furnace where the metallurgical operations are carried on. After leaving the coil or superheater O the pipe terminates in a jet or nozzle, g, which enters the enlarged portion of pipe G beneath and surrounding the delivery point of pipe D. D is a pipe leading to a second hydrocarbon-reservoir, and is provided with a stop-cock, d, to control the flo vs ,of liquid or vapor. The pipe G terminates m a joint, 0, which connects it with pipe E, and a second joint, 6, connects pipe E with p pe or nozzle H, the several connections formlng a universal joint, whereby the gas can be d1 rected to and burned at any point desired.

J OSEPHUS CHANDLER AND DAVID A. WRAY, OF PIO N EEE PENNSYLVANIA. Y

- -'-"-:W h'en liquid hydrocarbon is used it is fed through pipes B and D (the flow being con;

trolled by stop-cocks b and d) intothe enlargedportions of F and G, where it 1s vaporized by. the jets of air or steamand gas. In I this case the reservoir should be above the level of the apparatus; or other. means should I be provided for'securinga steady flow 0f the hydrocarbon.

When a hydrocarbon vapor is used the vessels or reservoirs should be made of iron or other suitable metal, and arranged with heating-compartments, the vapors generated being conducted into pipes B and D, and'from thence taking the same direction and going through, 1

a similar process to that employed when the liquid is used.

The operation of the device is thus described A jet of steam is admitted into pipe A and passes through nozzle f into pipe F, carrying with'itthe vapor or vaporizing the liquid hy-,

drocarbon admitted through pipe B. The gas thus generated passes into the superheater or coil ,O,,. Where it is subjected to heat and be; comes a fixed gas. This fixed gas, as it issues from nozzle 9, meets a new portion of hydrocarbon-vapor or liquid, which it at once seizes upon and converts-into a gaseous or vaporous state, itself becoming surcharged or carbureted. The gas then flows through pipe G to nozzle H, and is burned.

Inth above statement of operation whenever th'eivord steam is used air or oxygen may be substituted, asthe jet entering the pipe A maybe eitherair, steam, or oxygen, (gen eratedby'any of thewell-known processes,) or of 1 two or more combined. When a great amount 1 of heat is required a number of jets are co1nblnedzz p v Having thus clearly described our invention, what we claimie- 1. The process herein described for generating and ee bn et g xed gas or chmpound blow-pipes and. similar apparatus.

2. The combination of the steam a r heir jet, the hydrocarbonjet, and the' super-heater, as and for the purpose herein set forth. i

' 3. The ooinbinationof an air or steam jet,

a. hydrocarbon-jet, a super-heater, a. earbureting or second hydrocarbon jet, and a nnivergel Intestiihony that we clairn the foregoing we have h reimto fii nefl r names t i-ie 17th sla of May, 1872.
