BARREL-HEATER.

SPECIFICATION forming' part of Letters Patent N o. 689,294, dated December 17, 1901.

Application led October 23, l900.' Serial No. 34,030. (N0 model.)

T0 @ZZ whom, t may concern.-

Beit known that I, ELMER E. DoUGLAss, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Barrel-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specication, in which the figure is a side elevation, partly in section, of my improved barrel or keg heater.

My invention relates to apparatus for heating or charring the interior of barrels or kegs. In apparatus heretofore employed-for this purpose it has been found difcult to evenly heat or char all parts of the inner surface owing to unequal distribution of the heat. My invention is designed to overcome this difficulty; and it consists in employing an annular series of gas-burners, the ame and gases from which pass upwardly within a shield or case and then enter a central outletilue,which extends downwardly throughthe space within the annular series of burners.

It further consists in providing a heatingdrum with a mass of heated lump material which extends the major portion of the length of the drum, the drum having an upper outlet for the gases. The refractory material thus extending up within the drum diluses and extendsthe combustion, thus giving a more extended and uniform heating of the mass and a more uniform charring of the keg or barrel.

It further consists in the construction and arrangement of the parts, as hereinafter more fully described, and set forth in the claims.

In the drawing, 2 represents a stand or platform carried on supports 3, and 4 is an annular barrel o'r keg support mounted thereon.

5 is a cylindrical heating-drum having a top cover or closure 6, this drum being of a suitable size so that the keg or barrel 7 may be slipped down over it. At the lower end of the drum an annular blast-box 8 is formed, through the top of which project a series of burners 9. Below the box 8 is an annular gas-chamber 10, from which a series of tubes 11 project upwardly into the burners, the gas and air mixing within the burners in the usual manner. Air is supplied to the windbox through a pipe 12, and gas is similarly supplied to the gas-chamber through a pipe 13, these pipes having suitable controllingvalves.

To the center of the platform or table is secured a depending box 14, Within which is carried the oiftake-iiue 15, which is preferably formed of hollow tiles and extends up- Wardly to within a short distance from the top of the drum. From the lower end of this offtake-flue l5 leads the stack-fine 16. The annular space between the central offtakeue and the heating-drum is filled with-refractory material 17, which is preferably in the form of broken pieces of tile or fire-brick.

4In using the apparatus, the keg or barrel being set down over the drum, the flame and gases from the annular row of burners, passing up through the annular belt of refractory material, heats it to a high temperature, and this heat is radiated through the drum to the inner surface of the keg or barrel. The products of combustion entering the top of the flue 15 pass downwardly through it into the stack.

The advantages of my invention result from the even and uniform heat which is obtained by using the annular series of burners within the drum and also from the use of the refractory material, which stores up the heat and equalizes the heat throughout the drum, so as to give an even oharring of the barrel. The placing of the apparatus upon the elevated table is also of advantage, since it permits a free circulationof air beneath the stove and also serves as a support for the stack-iiue.

Many changes may be made in the form,

size, and arrangement of the parts without departing from my invention.

I claim-a 1. A barrel a heater having a cylindrical drum, a base arranged to support the barrel or keg in position around the drum, a central offtake-iue extending downwardly from within the upper part of the drum, an annular zone of granular refractory material be tween the flue and the sides of the drum and arranged to extend upwardly the major part of the length of the keg or barrel, and gasi burners projecting upwardly in the space containing the refractory material; substantially as described.

2. A barrelheater having a cylindrical heating drum, with a central offtake iiue therein, a base arranged to support a barrel 'or keg in place around the drum, and an annular belt of heated lump material between the iue and the drum, and arranged to extend upwardly the major part of the length of the barrel or keg; substantially as described.

3. A barrel-heater having a heating-drum carried on an elevated base or support arranged to allow air circulation below the heater and support the barrel or keg around the drum, a mass of heated lump material within the drum and extending the major part of the length of the barrel or keg, an upper outlet for the gases, and burners projecting upwardly into the space lled with the lump material; substantially as described.

4. A barrel-heater having a heating-drum provided with acentral downtake-flue and a zone of refractory material between the flue and drum and extending upwardly the major portion of the length of the drum, an annular box below the drum, an annular series of mixers provided with burners projecting upwardly into the annular space containing the granular material, and a base arranged to support the barrel or keg around the drum substantially as described.

5. A barrel-heater having a heating-drum with a central offtake-due, a base arranged to support the barrel or keg around the drum, a zone of heated lump material between the fiue and drum and extending upwardly for the major part of the length of the drum, an

annularair-blast box beneath the drum, mixers having burners leading from the blast-box into the refractory material, and gas-supply tubes leading into the mixer; substantially as described.

6. A barrel-heater having a drum containinga mass of heated lump material extending the major portion of the length of the drum, said drum having an upper outlet for the gases, and a base or support arranged to carry the barrel or keg in place around the heating-drum; substantially as described.

7. A barrel-heater having a drum containing a mass of granular refractory material extending upwardly for the major portion of the length of the drum, said drum having an upper outlet for the gases, a base arranged to support a barrel or keg in position around the drum, and burners arranged to direct their iiames upwardly into the refractory material; substantially as described.

8. A barrel-heater having a heating-drum with a central oiftake-flue and surrounding refractory material extending upwardly for a major portion of the length of the drum, an annular Yblast-box beneath the drum with burners projecting upwardly thereinto, a rest around the lower part of the drum to receive the barrel, and an annular gas-chamber loeneath the wind-box with gas-supply tubes leading upwardly into the mixer; substantially as described.

In testimony whereof I have hereunto set my hand.

ELMER E. DOUGLASS.
