Leners Para; No, 84,148, dated November 17., 186s.

-To all whom tt may 'conce/m Be it-'known that I, EDWARD W. TAYLOR, of Norristown, Montgomery county, in the State of Pennsylvania, have made an invention of which the following'is a full description, reference being had' tol the accompa;

nying drawings, and to the'letters of reference marked My invention consists of a process of producing heat and other eiects of combustion through the employment of currents of air and of steam assisting inthe combustion of petroleum, shale, and other oils, grease,

tar, and other carbonaceous substances upon afgrooved plate, A; vthe fire burning upon the surface of the fuel,

-whchis 'introduced directly to the combustion, instead -of being first reduced tothe condition of gas, 'or otherwise treatedin any retort or other preparatorychamber,

and without the employment of any blower' or donkeyengine, or other supplementary machinery, except ordinary pipes for-supplyinglainor steam', or fuel.v

'The-apparatus by which the processie' applied v.is

illustrated bythe drawings aforesaid, and may be thus more specifically described.

, The burner proper, Figure 1, B, is box-shaped, of

dimensions to accommodate it to the available space underneath4 the boiler, or to any other space where it is desirable to apply the llame. f

The interior is an air-chamber or box, closed on all sides, except thatthe front end, a, is open for the admission of air, Communicating with the fire-chamber C, above, thereare the principal air-passage l), at the rear of the burner, and air-holes l) b b, at'the cud and along the ridges of the groovedplate, which plate constitutes the top of the air-chamber, and upon it the fuel burns.

In this plate, and surrounding the main air-passage D, are grooves or channels ce-c' c, in its surface, which hold the4 fuel; and which principal grooves have connected with them supplementary grooves d d d d, somewhatmore shallow, extending forward tothe front of the plate, which take up a portion of the fluid fuel,ii` overl abundant; and also,'if filled-when the fire is first started, assistkby this increase of burning-sulface beyond what is needed after steam is' up, in raising steam Without delay.

The air-passage D is surmounted by ahollow-incomy bustible receptacle, E, to which steam is conducted,the

moment it begins to form, by the pipe F. This pipe supplies the receptacle E with the exhaust steam from the cylinders in all cases' when it is practicable, as in high-pressure engines, thus eife'cting a saving ofso much live steam, besidesincreasing the supply of steam to the combustion, in proportion to the increased speed of the pistons, which are also in this manner relieved from the backward pressure of the exhaust steam.

The steam-receptacle is made with retreating sides,

a convenient form of which is seen in comparing letter E in the various figures in the drawing, and the base of it, e e, Figures 1, 7, and 10, has projecting arms hv h,

which-.fit closely the sides of the air-passage, holding the steam-receptacle steady in its position, at the same time allowing it to be moved up or down, so as toregulate the Vsize of the opening -or crevice between' its sides and those of airchannel D, and so regulating the amount of air ascending that passage.

The flames from the fuel surrounding this receptacle,

heatto intensitythe steam in it, which issues through apertures' f f f f, extending upwards fromwithin, outwards through the sides of the receptacle, and, striking the ascending air just before it arrives at the point of combustion, throws a current of mixed air and steam, highly heated or decomposed, with great force, into the darne of the burning fuel.

lhe liamesrising against an arch of lire-brick, or

other incombustible material, G, which covers closely the burner-plate, are doubled upon themselves, and rolled forward, receiving fresh oxygen from the apertures b b b, and at the front H, -until they escapebypassf p ing overthe archG, and back again lover the top of it,

andA beneath the boiler I, or other object to be heated, and' so into the iiues or tubes of the boiler J J.

By this'process, heat of great .intensity is produced, and combustion so perfect ofthe material supplied, that no portions remain unconsumed to pass, in the shape of smoke, into the smoke-stack. Neither is there any waste, in the shape-of ashes and coke.

In case the 'flame is used for' metallurgie or other purposes than in connectionwith a boiler above, the arch Gg may have to be differently arranged, for instance,

whenused in the ordinary-'shaped steam-lire engines,

as hereinafter referred to.

The fuel, if liquid, is supplied by a pipe, K, passing through the 'air-chamber B, from which pipe, branchlpipes g g ascend through the air-chamber, and discharge their contents into the grooves or channels c c of the burner-plate.. I arrange these pipes with T -shaped heads, which discharge at both sides, S S.

.To supply" more steam, and in more `intimate union with the fuel, as we ll as to prevent any incrustrations .of the nozzles of theT-heads, and the possibility of stoppage in the pipes, I supply steam to the oil-pipe, at any convenient point, as L, in the drawing.

M is a pipeconnecting with the oil-pipe, for the purposes of supplying an additional fuel, in the shape of gas from oil-wells, when the burner is employed in connection with such wells; the gas beingconductedinto the fuel-pipe at the-most convenient point, as I.l,passy ing through a piece of wire gauze, inserted at the point of connection of the pipes, which may be by an ordinary union. This gauze prevents the possibility of any danger from the use of the gas aforesaid.

. In accommodating the plate-burner to steam-fire engines, as now constructed, the shape of the arch must be varied to suit that of the hre-chamber, and the supi' plementary grooves, el 'd d d, would probably have to radiate from the principal grooves surrounding the airpassage andsteam-receptacle as a centre.4

To prevent cracking of the lower by the sudden eX- pansion of the upper portions of the air-box B, I'make the box in two portions, the` upper portion being of cast` iron, and being bolted onv the lower portion, O, as seen in Figure 2, which is best made of boiler or sheet-iron;

To increase the supply of air,'in'st'ead of a door, I'

use a scoop of sheet-iron, projecting inwards and downwards, as seen in H, Figures 1, 8, and 9.

Bolted to the front end of the plate-burner, at P, is

an iron sliding plate, of the width of the burner-plate,

made with slots to accommodate the bolts. This slide can thus be drawn' ont to a greater' or less distance, ac

cording to the size of the iire-box, and closing up the space between the end of the plate-burner and the front opening.

Earth is then iilled in alongside of the plate-burner,

making a fire-chamber, O, open onlyin front, at whicl1` cent fuel on the sru'face of an open plate, surmounted and combined with an incomb'ustible covering, Without the intervention of sand or other materials, the combustion heilig facilitated andthe effectsintensiied by the employment of a current of steam passing into the' re-chamber, substantially as shown and described.

- 2. Theblast-appa1atus assisting in said process, being lthe arrangement described, 'of the air-passage D, in

combination with the steam-receptacle E, arranged to move up and down, and the method of bringing heated steam into union with the air at a point and/in a mode as described, so as to form a lmost intimate union, and atthe same time creating a powerful blast, conveying the mixture into combination with the burning fuel. i

3. The combination vof a fuel-plate with a blast-apparatus, assisting' in the combustion of liquid and liquescent fuel, substantially as shown and described.

4. The slideP, as a device for the purpose of accommodating hydrocarbon-burners to fire-boxes and other spaces of varying sizes, without requiring l'the burners in such cases to be constructed on diii'erent scales.
