UNITED STATES PATENT wrLLiAM TILDEN Penton, oF NEW YORK, N. Y.

vSpecication forming part of Let-tere Patent No. 113,338, dated April 4, 187i..

To all whom it may concern:

Be it known that I, WILLIAMTILDEN PEL- TON, of the State, county, and city'ot New York, have made an invention, of which the following is a full description, reference being had to the accompanying drawing and to the` letters of.reference marked thereon.

My invent-ion consists of au apparatus and arrangement of machinery whereby railroad ties, timber, and other wood and suitable substances may be seasoned and impregnated with preservative elements, whether of h ydro earbtms, oleaginous, saline, or other materials, in such manner that said substances shall be etectually and economicallytreated, and, by the employment of said appaiatns--the same bein g movable to the desired point-:treating of wood at distant and separate points' along theline ofrailroads shall be possible andprolitable.

1t would be impossible to establish a fixed treating apparatus at every p oint where railroad ties, posts, timber, 'or other substances are to be'fouud suitable for creosotin g along the lines of railroads; ,and it might be diticult to nd localities that so abound in the desired material in such supply, and alsothat furnish such a market as to justify the outlay necessary to erect a treatingapparatus for that 1oeality. Itis 'generally true that the supply of y proper timber is quite limited at any given point, and so, also, the demand for the treated article 5 and that the timber has to be gathered from diii'erent points at great distances and distributed again, at great cost of handling and transportation. The employment of my invention requires but outlay suiiicient to build one apparatus, 'and enables the operator to treat ties, posts, and-timber at any and every point where a railroad branch or track extends without any previous handling or transportation of thewood and each owner of timber is able to have it treated with the same economyl as though he hada separate treating apparatus constructed upon his own premises. The handling alone of a car-load of ties in loading and unloading them to take ,them to different points fortreatment and return amounts to an additional cost per tie more than sufiicieut to be decisive as to the utility of using or dispensing with a ereosoting process.

My apparatus particularly adapted for the employment and practical application of the Seely process, referred toin Letters Patent Nol 69,260, granted lSeptember 24, 1867, to Charles Seely, under which I became assignee, and where wood is seasoned or impregnated with liquidsas the seasoning orimpregnating materia-l, and where it is desired to trst apply them heated to 'the wood,in a manner to expel the sap andother contents of the pores of the wood; and, if impregnation is desired, then `to produce a vaeuumtherein by bringing in contact with 'the wood impregnating material of a lower degree of temperature, which at the same time supplies itself to till the pores ofthe wood without exposure to the air. Yet said apparatus can be employed whatever'the heatin g or treating material used, and whether the desired treatment be by a cold bath or a hot bath; or by alternate baths of hot and cold; or by baths gradually changing from hot to cold; or whether exposure4 to the air is desirable at any stage of the process or otherwise; and the cars described can be used separately or together.` rlhe same is true that can be propelled or drawn npon a railroad track or other roadway as a portable machine, specially useful for treating railroad and other ties, posts, and timber upon the lines of railroad, I have invented a new and useful apparatus, delineated in the accompanying drawing, as follows:

Figure lis a plan of the said apparatus and its various parts and adjuncts, and Fig. 2 is a side elevation ofthe Sallie.

'1 represents, when D is shut down, aclosed chamber or tank, in which the wood or other f substance is treated. The most desirable form I find to be that of a parallelopipedon, about twenty-live feet long, eight feet wide, and six feet high, and the best material light boileriron. R1 R2 are closed tanks, communicating with each other and with T by means of `the pipe a a at the side, and constructed above' FFIcE.-

aiidhelow T t'or the-purpose of containing thel aboutv one foot in diameter. S represents a frame and pulley, by means ot4 which to raise 1). D' isadoor swinging npoii its upper edge, 1 andforlosing T lierinetically tight. t is al truck, upon which the substance to he treatedl is piled, and running npoii m mL-wliich is anliiicliiied track passing into T, and 'descending into a continuation ot' man. Gr are .the trucks j or running-gear'supportiu g the treating apparatus. g is a funnel or opening to the pipe u,

through which the-'treating' material is poured into R2. E is an engine, supplied with steam from the boiler B, which may be located, as described, on u, a platform-car, or may be the boiler ot' a locomotive iii front. P is a force .puinp, operated by/E, pumping the treating 'materiali'i'oni R2 through the lpipej', aiidi'orc Vingitiinto Itl through the pipe g. @Lis the dem@supplyingsteani to E bymeans et' I, and .f alsoI 'supplying steam to heating-coils p p p ,in

the bot-toni,otT'tlirough the 'pipe djii.- .H is a drum, worked hy E, over which passes r, whichv iis arope attached to one and the other end ot' t, as itfhasv to he drawn in or out of T. To draw t out ot'T sheaves have to be arranged at confve'nient. points to lead i' around to the open vt'iiidof T. ccc sa pipe, with arms descend-l ing 'into' the top oteach dome, making a. con- Ynection between them, and also with O, which isaiifordiiiary condenser with a coilot'cooling- 'pipes in the bottom. (See also Fig. 4.) bb is "an overtlow-pipe tol T, and connect-ing two -treating tanlts, T and T, throughl 'the .rear

jdoines, on a plane lower than that of ccc, and

I lower, also, than a1 a emerges from R131. oo i 'of o' are pipes connecting It* with R1 and;V R2

withv R2 on different treating-cars, when used .f

in "conjunction, as it is quitedesirable to do. In order to have as large a reserve of cold treat-ing' material-as possible to be contained on cars in proportion to their'capacity to con-- tain Wood to be treated, and with'two treatingcars, you can alternately lill and-'empty T and T, and empty the treating material iu the tanks connected by o o o ol as though in two common reservoirs, R1 and'RZ, of double-the actual size.-

' Besides' the hot bath, the cold bath, the drawing olif the liquids, or the removal of the wood., or other steps in the process-of treatment,

' would occur in the case ofthe combination of two or more treating-cars at dii-ferent instants oftime, with reference to the diierent cars and the same stage of the process, so that in a com -binatiou of treating-cars every step of the process could be observed, transporting simultaneously in diliereiit chambers, and with a minY iinum of treating material and of labor, fuel,

time, and expense. i

Fig. No. 3 isa cross-section through two treating-cars, in plane .c w, showing the treatingchambers T T, with truckstt Within, on the track m m', and theI steam-pipes for heating p p p p underneath; also, the tank Rl R1A above,

and R2 R2 below, and the piped a with stopcocks 4, 2, and 5 connecting the several tanks on each car; also, the domes DD and the overow-pipe b with flexible `joint and stop-cock 1;

` also, the connecting-pipes o o o" o,.with iexible Fig. No. 4- isfacross-section' ot the saine v through the plane z z, sliowingthe condenser @,the domes DjlD.' connected from their tops by the pipe c c, with a exiblejoiiit anda IT passing into C; also, showingthe ends ot'tlie treating-cham bers T T, the4 running-gear' G G,

and the steam-piped dwith flexible joints.

The niannei'fiii .which the apparatus descri bed a is employed. in usiugthe'Steely-.process is as' follows The'truck t, together with the inclined track m mi, having been placedl within T, and D closed down, and., theifariouscnrs attached to each other aiidtogf-fth'e! `-u'intive power, "t he train or cars are moved tu4 point where the wood-js freqiiiredftobetr 1 There-D is raised, mtgn/ is adjusted to A1 and to m m.; the 'wood vis piled-uponltf'ris'fattached; steam from lBjs applied to E to'tu-rii'H' iin-til tis within' T.' Th'en .D Vis loweredfanil fastened liermetically hy bolts or slots, or, asthecaseinay be, R1 having been vtilled by the heating material pumped .from R2 through/fand g by means ofrP, the material in R2 having been poured in at 'g through n, another treating-car being joined by o o and o o. Then, 5 being closed, 4 and 2 .are opened inthe ii'rst until Tis tull or the woodamply submerged, and -2 is closed. Then steam from Lis let' intoipp p through d,

heat is obtained sufficient to driiethe sap out of the wood, and then.v the steaniis letout ot' p p p and 7 is shut. 2 is' a-gaiiiopened, R! and R2haviiigbeen reiil1ed, as\ before, and the seeond treatin g-ca'r, having beenlled with'wood to be treated and tightly closed, 1 is opened, whereupon .the heated materialrises upon the top of the colder material enteriing; at 2, and

passes'over through b'b upon the wood' in po sitiou in the second treating-car. This is continued till the second T is lled with the-heat'- ing' materiall and thecold material is substitilted in the irst T. lIfiinpregnation is desired, then 1 is closed; and-S opened, and steam supplied to-pp p vin the second T, and theheating process goes oittherein while the cold bath is' being applied in the first T. The gases and other volatile lproducts passing through c c c -into the condenser C, 3 and 6 being alternately open and shut to secure that end, this art rangement preventing' the danger that would exist of explosion ifa covered tank were used for a treating-chamber Withoutthe apparatus described, and preventing also the oii'ensive nuisance and waste oi' material that wouldenesca-pe as from an open vat.

' 1n g taken up into its pores a sufcient amount of the impregnating material in the first chamsue it' the volatile products were allowed to The Wood havber, and the wood in the second chamber having beensuiiciently heated,4 is shut and 5 is opened in the first treatin g-car, and the treating material in T passesinto R2. Then Dl is raised; r is run around sheaves to the front of TA attached to t, which is started out-,if necessary,

by proper motion heilig applied to' H. Other timber to be heated is run into T, which is closed when 1 is opened, and in the second car 5 is shut and 2 'and et are opened, Whereupon the hot materia-l passes over through b b upon; the woodin the first ear, and so on alternate y.

It is evident that there is a great saving ot' time, of labor, ot' material, and expense where there is a combination ot' two or more treatin gcars operated by the same force of men and steam.
