. lMPROVEMENT IN APPARATUS FOR PlTCHlNG BARRELS.

The Schedule referred to in these Lettera Patent and making pari: of the saine.

To whom it may concern .j

Be it known that I, Louis ScnUczn, formerly of Louisville, Kentucky` now of the city and count-y ot' Batimore and State of Maryland, have invented certain new and useful Improvements in Apparatus for Pit-ching Barrels, of which the following is a specitieation.

In order to coat thc interior of barrels, to render them impervious to water, pitch is used. lhis has been done by introducing` melted pitch into the barrel, or hy melting the pitch after it hais been put into the barrel. 'lo eti'ect the latter result it has been suggested to injectheated air into the barrel, but no apparatus has been devised for the purpose which can the neck or upper part of the same, so that the air shall pass into the conduit or pipe D without any violent oi' sudden change of direction.

For convenience sake I make the upper part, C, of the furnace separate from the lower, l, so that the former may be taken off whenever necessary; and, to secure the part' G inpropcr position, l make use of a fastening, whereby it may be tightly held to the latter, this heilig necessary as well to prevent .any csca'pc o air when the apparatus is in operation as to hold together the parts lofv the furnace in case they should be moved bodily and together.

As shown in the drawing, this fastening can be a bayonet-lock, so, calledthc part C having inclined edges, c, fitting on similar edges, b,formcd on the part B, which, when turned in one direction, willlock together, but will unlock when turned in the opposite direction. g

The upper part of the retort is thus prevented from being blown oti' or displaced by the force of the blast, and can yet be easily removed for the purpose of cleaning, or iilling,'or repairing the retort. Under ordinary circumstances, however, I can till the furnace or retort through adoor, G, formed in the upper section 0.

Tue door has beveled side edges,`as shown in iig. 4,' fitting into similar grooves in the section C, so that it may be-easily removed for the purpose offillingthe retort, and again closed tightly. Y, l

In the upper part of the retort, and, preferably, in the door G, I also form an opening, H, covered with isinglass suitably held in place, the object of Vthis arrangement being topcrmit the operator to observe the force of the blast, in order that he may the more accurately regulate the same. y

The supply of air is maintained by means o fa fan or other suitable air-forcing apparatus, F, which con# nects with the pipe 1 },t`ne arrangement of which has been already described.

' The blast-conduit or pipe which leads' from thc furnace to.thc barrel should be provided at the end which My invention, therefore, relates to this mcthodof melting the pitch in the barrel by means of a blast of4 lt consists of certain improvements in apparatus, which allow the air, carrying with it the inflamed products of combustion, to he introduced into the barrel, which render-the apparatus capable of being fitted to barrels of various sizes, and adapt' it to be transport-ed with facility from place to place wherever its services are required. h The manner in which these results are or may be attained will be understood by reference tothe accompanying drawing, in which4 Figure 1 is a side elevation lof au apparatus ein'- Fignre 2 is an elevation of a portion of the saine.

Figures 3 and4 are views of detached port-ions of the apparat-us hereinafter referred to.

The furnace through which the air tobe heated passes on its way to the barrel is represented at B. The air enters at the lower part O of the furnace, through the pipe E, in such manner 'that it is forced upward through the fire vertically, or practically so, thereby passing, with but little or no change of direction, to the outlet or discharge-pipe D, through which The furnace is supported above the ground iipon a stand or frame A, which is portable, and can, with the furnace which it carries, be moved from place toplace, as desired. By thus Isupporting the furnace I am also enabled to connect the pipe E with the bottom of the furnace, and so obtain, without diiculty,lthe direct upward blast through the fire-` This arrangeincntis :iisd advantageous on other acconn'ts, as it gives me free access to the lower part or bottom of. the furnace, if at any time, or for any' reason, it should bc found desirable or necessary to have access to it.

I prefer to .make the furnace of a retort-shapmas shown in the drawing, and to bend or graduali y. incline barrel and preventing it from being charred by contact with the heated pipe. For this purpose a water- Jaeket, f, may be arranged around the 'cnilv of tire pipe,

shown in iig. 1. This jacket carries-'a small reservoir, g, which coinmunicatcs at its bottom direct-ly wit-h the jacket, and is also connected at its top with said reservoir by a tube, h, arrangcd'as shown. t

Any water that may be vapnrizcd in the jacket by iers the upper partotthe rcservoh, where it will conense. v

tits into the barrel with some means' for-protecting the where it is inserted in the. bung-hole of the barrel, as

the heat of the pipe rises through the tube h and cndesired.

-. or condnitwhi set l'ort-h, whereby the air It may be found desirable blast toward all portions ofthe barrel in succession; and to this end I conneotthe pipe Dwith a short pi'pe, e, in such manner that the said pipe e can revolve lreshly.' i

The inner end of the pipe, which isl within the barrel, iseurved, as shown in iig'. 3, and provided with slots and openings, 11j, suitably arranged, so that, when the apparatus is in opeiation, the blast will be thrown out with great force through saidopening into the barrel. By revolving the pipe its curved end will direct the blast toward the bottom, top, or sidesof the barrel, as The tube can be thus revolved by means of a handle, L, att-ached to it.

,ln order tofadapt the .apparatusr for use with barrels of diti'ercnt sizes l provide a vertically-adjustable plattbrm or table, J, which can .be raised or lowered by means of a lever-trcadle. K; or by equivalent means.`

The barrel, when placed on the table, is elevated, by depressing the treadle K, to such a height as to pernlit'thexblastfpipe to be inserted in the bung-hole.

Any suitable device t Suray table J in place while the barrel is being pitched, and

vthe treadle may he connected with the' table by a ballaud-sockct or universal joint, .table to revolve, if desired.

By forming the furnace with sides gradually incliningand drawn in towanlthe opening or conduit through which the air passes from the 'fnrnaoe'to the barrel. the blast, as above stated, is grzulually condensed and concentrated,`a nd is guided toward the barre] withoutany violent change nl' dilection.

'.lhe mouths of the two pipes-D E are almost diametiically opposite each otherthe one in the top, the other in Lhe bottom oi the furnace-so that the air, in passing out from the one-through the fire and into the other, will pursue an almost straight course.

The operation of the apparatus will be readily understood. Theblast created hy t the l'umacc, up through the lire, and intov tl le conduit I), where it is discharged, along with lthe inflamed pro- -ducts ot' combustion, into the barrel.

A vent in the topof the barrel allows the-smoke,

which will permit the 'ahgdtc7 to escape.
