PlTCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 440,297, dated November 11, 1890.

Application filed August 23, 1890. Serial No. 362,839. (No model.)

To all whom it may concern:

Be it known that I, VVILHELM ARNEMANN, of the city of Hamburg, in the Empire of Germany, have invented a new and useful Inlprovement in Pitching-ll/lachines, of which the following is a specification.

The object of this invention is to provide for carrying olf from a pitching-machine the vapor or smoke produced during the process of pitching.

The improvement consists in the combination, as hereinafter described and claimed, of a smoke-extractor with a pitching-machine, whereby both the pitching-machine and the extractor constitute one transportable apparatus.

Figure 1 in the accompanying drawings represents a front elevation, partly in section, of a pitching-machine with my improvement. Fig. 2 is a plan view of the same partly in section. Fig. 3 is a side elevation of the same, partly in section.

Similar letters of reference designate corresponding parts in all the figures.

The furnace A of the machine is of known construction, having within it a fire-place for a fire of coke, into which fresh air is to be introduced from a blower through a tube 01, to be heated therein and led therefrom through tubes 0 to the nozzles 3, upon which the barrels to be pitched are placed.

The smoke and vapor extractor consists, principally, of a box or hood B, partly surrounding; the upper part of the furnace and having provided in its bottom tubes h, each of which has for each tube 0 and nozzle 5 two branches h and 7L2, that are arranged in such manner shown that after the barrel to be pitched has been placed on or over the corresponding nozzle 0 the tube 7Z2 terminates underneath the bung-hole of the barrel and the corresponding tube 72/ terminates near the tap-hole. A tube at leads from the box or hood B to an exhauster, which may be of any known or suitable kind not necessary to be shown.

While operatingthe machine hot air from the furnace enters the barrels through the tubes 0 and nozzles s and melts the old pitch attached to the inner surface of the barrels. This pitch runs out of the bung-hole near the sides of the nozzle into a reservoir 6. At the same time the exhauster removes the smoke from the barrel through the tubes 7?. and 71 into the box or hood B, and thence through the tube d into the atmosphere, or to a place Where it cannot molest the workmen or other people. The suction-tubes h and h can be closed each by a slide or flap to close one or more of the same toward the box or hood B if the correspol'lding tubes 0 and nozzles s have to be shut out from work. The ends of the tubes h are made telescopic to provide for a close fit to the barrelsurface.

hat I claim as my invention, and desire to secure by Letters Patent, is

The combination, with the furnace A, the hot-air pipe 0, and nozzle 8 of a pitchingmachine, of a box or hood B, arranged near the said furnace and provided with an exhaust-pipe (Z and with tubes h 71 for forming communication,respectively, with the taphole and bung-holes of a barrel placed over the said nozzle, substantially as and for the purpose herein set forth.
