The burner is attached to the end of a gas-pipe C, which receives its supply of gas from a header or pipe 0, leading from anysource of supply, and, as shown, the pipe O is provided. with a regulatingvalve 0, by means of which the gas-supply to the burner can be regulated as required. The air for the support of combustion and to be heated for effecting the drying of the barrel is supplied from a pipe D, entered into the chamber or space at beneath the burner, and the pipe D receives a supply of preferably compressed air from a header or pipe D, leading from any suitable source of supply, such as an air-compressor or a coinpressed-air reservoir, and the pipe D is provided with a regulating-valve d, by means of which the supply of air through the pipe can be regulated as desired. The air under pressure is projected from the pipe D into the chamber or space a and passes up into the fire pot or chamber A in the annular space around the burner, and this air serves to sup- .port and produce perfect combustion, and in quantity the supply is in excess of the amount required to produce perfect combustion, and such excess after the fire-brick' or other refractory material in the fire-pot has been brought to an incandescent or white heat becomes heated and passes up into the barrel, furnishing dry intense heat unaccompanied by any flame, as the pressure of the air operates to cut down the flame, which remains in close proximity to the burner and cannot pass up through the fire pot or chamber and enter the barrel. It will thus be seen that'the dry heat'for operation on the barrel is simply the hot dry air brought to a degree of high intense heat in its passage through the fire pot or chamber before delivery or admission into the barrel, the result being that this high degree of intense heat or hot air is the only medium which acts in heating and drying out the barrel.

The fire-pot and its surrounding shell or wall and the lower ends of the gas and air pipes leading to the fire pot or chamber in the arrangement shown are located in a setting E of any suitable material, and, as shown in Fig. 1, this setting is continuous and adapted to receive two fire pots or chambers and their coacting appliances side by side. The setting above each fire pot or chamber is provided with a chamber E of a greater diameter at the top than at the bottom, having, as shown, an

outwardly and upwardly flaring wall or side.

On the top of the setting around each chamber E is a plate E from which depends a central conical-shaped deflector e, and the top of the plate around the central deflector is provided with a series of radiating openings or passages e for the discharge of the dry hot air which enters the spreading-chamber E from the fire pot or chamber. The conical central deflector is located in line with the center of the fire-pot or combustion-chamber and operates to produce a deflecting of the hot air on all sides for such air to pass up through the radial openings or passages e into the interior of the barrel.

The casing or cylinder F for inclosing the barrel has its upper end closed by a suitable cover, and this casing or cylinder, in the arrangement shown in Fig. l, rests at its lower end upon the plate E so as to surround the openings in the plate for the projected hot air to pass up in to the casing or cylinder. This casing or cylinder is of a diameter and height sufficient to receive a barrel within itsinterior and wholly inclose the barrel. As shown, it is provided on opposite sides with slides f to run on the pipes or tubes 0 and D, so that such pipes or tubes furnish the guides for rais= ing and lowering the casing or cylinder. A cross-piece G is located between the two pipes O and D near the top and is secured to each pipe in any suitable manner, and a second cross-piece G is located between these pipes and secured to each in anysuitable manner and is arranged at a sufficient height to serve as a stop for the casing or cylinder when it has been raised. A rope or cable g is attached to the cover of the casing or cylinder F and runs over a pulley g on the cross-piece G, and to the other end of this cord or cable is attached a weight g, which serves as a counterpoise for the casing or cylinder and facilitates the raising and lowering thereof. It is to be understood that a casing or cylinder is to be provided for each furnace and each casing or cylinder is to run up and down on the pipes O and D as guides, though, if desired, separate guides could be provided, and the pipes C- and D need not extend vertically upward, but could be arranged horizontally. The barrel H to be operated upon is placed on the supporting ring or plate E, so as to be central in line with and over the fire-pot or combustion-chamber, and the inclosing casing or cylinder, which has been raised or elevated for the placing of the barrel in a position, is dropped or lowered, so as to surround the barrel, with its lower end resting on the plate or ring E in the arrangement shown in Fig. l, when the apparatus is ready for use.

In use gas is admitted to the barrel B, and the burner is lighted and air under pressure is admitted to the chamber or space a from the supply-pipe D. This air furnishes a support for combustion, and the heat of the combustion will bring the fire-brick or other refractory material I) to a high degree of heat, and when this point has been reached the excess of admitted air over and above What is required for-perfect combustion passes up through the highly-heated refractory material and is in turn brought to an intense high heat and reduced to a perfectly dry state. This dry and intensely-heated air passes from the fire-pot or combustion-chain ber into the spreading-chamber, and from thence is projected up through the openings in the cover.- ing-plate E into the barrel and within the inclosing cylinder or casing and through its force and hot dry condition operates on the interior of the barrel and the exterior also, so as to thoroughly and effectively heat and dry out the barrel. The hot dry air operates to produce a heating and drying effect on the barrel without any blistering, burning, browning, scorching, or blackening effect, as it is unaccompanied by any flame, so that the barrel is only subjected to a dry and intense heat, which heat is the most desirable and effective for producing the results sought of thoroughly drying out the barrel.

The arrangement shown in Fig. 1 will be found efiective and reliable in use; but instead of having the inclosing casing or cylinder rest on the covering-plate such inclosing casing or cylinder can be formed and arranged to pass down and surround the setting, which will prevent the admission of any outside air at the bottom of the casing or cylinder, as might occur with the arrangement shown in Fig. 1. A construction for the easing or cylinder to pass down around the setting is shown in Fig. 2, in which the setting at the upper portion instead of being continuous for the two driers is formed with a separate portion for each furnace, and the covering or supporting plate is continued downward, so as to encompass the setting and furnish a guide for the descent of the casing or cylinder and also forming a guard against the direct admission of exterior air around the top of the casing or cylinder to strike the lower end of the barrel. The effect of exterior air striking the lower end of the barrel might operate to prevent the thorough drying out of the barrel at the lower end; but with the construction shown in Fig. 2 the exterior air before striking the barrel would become more or less heated, as it must pass up around the setting in order to gain admission to the'interior of the casing or cylinder, and in such passage it will become heated, so as not to give a cooling effect.

The apparatus is exceedingly simple in construction and by its use the drying out of .the barrel is eifected without any liability of blast,which operates to produce perfect c0mbustion and cut down the flame. The location of the burner below the barrel and forcing the air through the flre-pot or combustion-chamber, filled with fire-brick or other a refractory material which can be brought to an incandescent or white heat or to a high degree of heat, enables the forced air to become thoroughly dried out and heated prior to its admission into the interior of the barrel to produce the drying effect, which is had from the action of the dry and intense heat arising from the projection of air under pressure through a bed or body of highly-heated material, which removes the moisture from the air, leaving only a dry and intense heat. It will thus be seen that by the use of our apparatus the drying out of barrels is greatly facilitated, and such drying out is unaccompanied with any ill effects, such as blistering, burning, browning, scorching, or blackening;
