To all wko-ml it may concern,.-

Beit known that I, HOWARD DUNHAM, a

citizen of the United sas City7 in the county States, residing at Kanof Vyandotte, State of Kansas, have invented a certain new and useful Improvement in Apparatus for IIeat scription, reference Io panying drawings, forming specification, wherein` Figure lis a vertical sectional view through my improved apparatus. sectional view on line 2 2, Fig. l.

and useful heating and set the stares g the same,

The essential features of this present invention reside in the peculiar vconstruction and arrangement of the heater, whereby the radiated heat is equalized and evenly distributed throughout the barrel or Cask; in the 3o provision of a plate or lid slidiri'gly supported on the heater, which is adapted, when the el, to accommoas a cover to heater is lowered into the bari' date itself to the top of the barrel and serve tained heat, vice on the prevent the escape of the conand in arranging a centerin g deupper portion of the heater, said centering device being adapted to project down through the suspended lid after said lid rests upon a barrel to center the heater 4o relative to the barrel; and, further, the invention consists in ment, and combin all as will hereinaf and afterward In the drawing which is slightly the construction, arrangeation of the several parts, ter be more fully described,

a telescopic smoke-pipe,

through which the waste products of combustion are carried o.

This smoke-pipe consists of a stationary section D,passing through the ceiling, or to asuitable section D, sleeved on said and secured at its portion of the heate The upper end of D is formed with flange CZ', through t pass guide-rods E, depending from the ceiling and connected at their lower ends to a ring c, which ring e serves to hold the lower ends sliding pipe-section F and F Iof therods in position and also to guide the indicate guide-arms the inner ends of which are fastened, preferably integral, to rings which are secured to the or dome-section o while their outer ends or posts G.

The more intense tion of the heater,

the heater and a centering device arranged on the upper part of theheater which projects through the lid when the heater is lowered and centers the heater relative to barrels of different sizes, the lid accommodating itself to barrels of different heights to retain the heat in the barrel being heated, substantially as described.

2. In an apparatus for heating and drying barrels, the combination with a heater which is adapted to be moved into, or out of, the barrel to be heated, and a plate or lid, suspended from said heater by flexible cords or chains,which plate or lid is adapted to accommodate itself to barrels of varying heights; substantially as described.

3. In an apparatus for heating and drying barrels, the combination with a counterbalanced heater, adapted to be lowered into the barrel to be heated or dried, means on the heater for centering the heater relative to the barrel, and a plate or lid carried by the heater and adapted to seal the barrel when the heater is lowered t-hereinto; substantially as described.

4. In a barrel-heater, the combination with the fire-pot, of a baffle-cylinder surrounding the lower portion of said fire-pot, and spaced therefrom, whereby, the radiation of heat is equalized throughout the exterior of the heater; substantially as described.

5. In a barrel-heater, the combination with a cylindrical .fire-pot, of an open-ended perforated cylinder surrminding the lower portion of said fire-pot, for promoting a circula tion of the heated air; substantially as described.

G. In a l awel-heater, the combination with a cylindrical lire-pot, of a perforated cylinder, of larger diameter than the fire-pot, arranged around the lower portion of the firepot, and rods secured to a i lange on the upper portion of the lire-pot, for suspending said perforated cylinder, whereby, a space is left between the perforated cylinder aud fire-pot, and at the ends of the perforated cylinder; substantially as described.

7. In an apparatus for heating and drying barrels, the combination with a heater which is adapted to be moved into, or out of, the barrel to be heated, aplate or lid, suspended from said heater by flexible cords or chains, which plate or lid is adapted to accommodate itself 'to barrels of varying heights, and one or more peep-holes in said plate or lid; substantially as described.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 23d day of October, 1896.

and, owing to the air-space and an updraft, part of said heat is driven upward and commingled with the heat radiating from the upper portion of the heater. Thus it will be seen'that the heat is practically distributed evenly throughout the interior of the barrel.

II indicates an annular plate which is supported from the upper portion of the heater by flexible cords or chains h. This plate I-I is adapted to rest upon the top of the barrel when the heater is lowered thereinto and close the opening to confine the heat within the barrel.

h' indicates peep-holes covered with mica, through which the operator may see the condition of the barrel during the heating and drying period.

The operation of my invention is as follows: The barrel is formed over a suitable form, the slaves having been steamed, as is usual, to facilitate their being bent to proper shape. The form is then removed and the barrel placed upon the platform A over the opening a, it being of course understood that the barrel is not headed at either end. The heater is now lowered 'into the barrel, the plate II covering the barrel to retain the heat within, so that full benefit may be derived from the radiated heat. After the barrel has become sufficiently dry and the staves set the heater is raised from the barrel, the barrel removed, and another placed in position and the operation repeated.

By my improved construction a simple, compact, and efficient apparatus is produced and one which is convenient and easy to manipulate. Its advantages over the style of apparatus wherein the barrel has to be elevated up to the heater are obvious.

My special construction of heater is far superior to those heretofore employed, as practical usage has demonstrated that a barrel may be thoroughly dried without scorching or charring the wood, which was not the case heretofore, because the more intense heat from the lower portion of the heater would invariably scorch the wood at the lower part of the barrel before the upper part had been properly dried.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my apparatus can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. In an apparatus for heating and drying barrels, the combination with a counterbalanced heater, adapted to be moved into, or out of, the barrel to be heated, of a plate or lid iiexibly suspended from the upper part of Witnesses:
