APPARATUS FOR HEATING AND PITGHING BARRELS.

SPECIFICATION forming part of Letters Patent No. 460,291, dated September 29, 1891.

Application filed June 30,

To all whoml it may concern: i

Be it known that I, FRIEDRICH JUNG, a subject of the King of Wiirtemberg, residing at Schorndorf, W'iirtemberg, in the Empire of Germany, have invented a new and useful Improvement in Apparatus for Heating and Pitching Barrels, (for which I have obtained patent in Germany, No. 41,542, dated May 18, 1887,) of which the following is a specification.

The object of my invention, as described below, is to burn out beer-barrels with a direct flame and to remove the danger of explosions, which are still of frequent occurrencein pitching barrels. It is a notorious fact that the latter far more frequently occurs especially when barrels are pitched by the application of hot air or steam than when an open iiame or direct re is employed. The explosive gases are generated and the explosion is produced generally on account of a want of atmospheric air in the barrel.

My novel apparatus is constructed as follows to obviate these disadvantages, and in the drawings, Figure l represents a vertical section, Fig. 2 an elevation, and Fig. 8 a horizontal section, of the same, while Fig. 4 represents the apparatus in use and on a reduced scale.

The apparatus consists of an outer tube A and an inner tube B, provided with the small perforations a and b, respectively, the latter tube B being lightly enveloped in some porous material d, such as asbestus, difficult of combustion, and absorbent or adapted to retain liquid or semi-liquid fuel, such as boiling' resin.

To enable the smaller covered tube B to be easily inserted within the outer tube A, the latter is made in two parts or sections, connected by a hinge at a so as to be easily opened. An air-supply tube C is arranged at the top of the tube A, which is somewhat tapering at its bottom to facilitate its insertion into the barrel. One half of the tube A is fixed to the air-pipe C, while the other half may be secured thereto by the screw c, and by loosening the said screw may be swung open. The tube C is bent over at its top and connected with a ventilator or blower by means of a hemp or rubber hose, whereby the 1891. Serial No. 398,088. (No model.) Patented in Germany May 13, 1887, No. 41,542.

necessary air for combustion is conveyed to the burning apparatus and the interior of the barrel is supplied with sufficient fresh air through the openings a2 of the tube A to prevent the formation of explosive gases.

rlhe apparatus operates as follows: The entire apparatus is dipped intoboiling resin, so as to till the middle tube B, and is then ignited and introduced into the barrel through the bunghole. Air being now blown into the same by the blower through air-pipe C, the resin is eX- pelled from the inner tube B and the flame intensied, so that the inner walls of the barrel become heated and the old resin adhering to the same is melted. rlhe old resin is then removed from the barrel, whereupon fresh boiling resin is poured into the same and the barrel is rolled and turned.

What I claim, and desire to secure by Letters Patent, is-

l. A barrel-heater consisting' of a tube, as A, provided with perforations, as ctand a2, in combination with a tube, as B, provided with perforations, as b, and arranged within the tube A, and a porous material for retaining the fuel arranged in the space between the tubes A and B, substantially as set forth.

2.' A barrel heating and pitching apparatus consisting' of a tube provided with lateral perforations, in combination with a perforated tube inclosed within the first tube and below the upper line of perforations of the same, said inner tube being enveloped in asbestus, substantially as set forth.

3. A barrel heating and pitching apparatus consisting of an inner perforated tube lightly wound with material for retaining liquid fuel, in combination with a perforated outer tube made in two parts connected bya hinge, substantially as set forth.

4. A barrel heating and pitching apparatus consisting of a tube, as A, provided with perforations, as o and a?, and formed in two parts hinged together, in combination with a pipe, as C, attached to one of the parts, and an inner foraminated tube, in material for retainingliquid fuel', substantially as set forth.

5. A barrel-heater consisting of the tubes A and B, provided with the perforations c',

9S as B, enveloped IOO a, and b, the latter tube being lightly Wound In testimony whereof I have signed this with material difficult of combustion, While specification in the presence of two snbserib- Io the former consists of two halves connected ing,r witnesses.
