application tiled November 2S, 1908. erialNo. 464,947.

lie it known t a citizen ot the nit-ed States. residing at Philadelphia. county of Philadelphia and itate t lennsji'lyania. have invented certain new and useful improvements in Railway 'l'ank-fars. oit which the following is a specification.

'this invention relates to the provision ot heating apparatus in the tanks of cars for transporting liquids on ailways, more especially such liquids as lubricating oils1 t'uel voils and other heavy petroleum vproducts which will not flow readily, it at all. at ordinary atmospheric temperatures. lieretoiore the tank cars in which such liquids have heen shipped have heen provided with steam heaters in order that the contents of the tanks may he `heated and so made more duid. when they are to he drawn oii' hy the usual drawoii pipes at the hottoms ot' the tanks; hut. so Jfar as i am aware. every pr vision her fore made orheating the contents or" railway tank cars has heen open to ohieetion on account of the liability 'the steam pipes composing the heaters al; at t. ints or to he loosened from to the walls of the tanks.

ions are largely at least overaid ot the present invention: in cordance with which in its hest and most fplete forni a numher of steam pipes are onnected each at one end with a header and e t suliicientiy free otherwise for them to Xpand and contract longittuiinally with changes ci' temperature: while the header is secured to the "tank hottom hy a flanged hase. weich may he as large necessary for a permanent fastening (or as may he desired) and vin which are hestiormed the passages (one or more) for the inflow of the st lam and the outliow o? the water or condensation. The iianget. hase is also hest formed with a reduced portion hetween the flange and the hody ot" the header'. and the header is best divided into two chamhers. one for steam and the other for the water ot condensation. the 1former heing connected hy smaller inside pipes with the outer ends of the inclosing whose inner ends are in direct communication with the latter chamher; out niodicat-ion in these and in other respects can he made so long as the suhstance is taken ot any one or more of the claims at 'the end oi' this specification.

The invention also consists in part in certain particulars of construction hereinafter set forth.

ln the accompanying drawings: Figure l is a view in vertical longitudinal and nearly central section of the tank of a railway tank car. provided with heating apparatus in accordance with the invention in its best and most complete form; Figs. '2 and 3 are cross v sections of the same on lines A A and B B respectively of Fig. l. looking in the direction ot' the arrows; Fig. fr is on a larger scale and is a plan view of the header. hroken away near one end to show a portion in horizontal section; and Fig. 5 is a vertical sect-ion on line C C of Figs. l and 4. Fig. f3 is a detail view in section on line D D of Fig. 4.

Vivithin the tank a. which is. as shown, of the customary cylindrical form and is to he mounted in a horizontal lposit-ion in any known or suitahle way on wheeled trucks and provided with draft rigging (not shown) for movement on the rails of a rail.- way. there are a nmnher of pipes con neeted each at one end with a header'c; which. as shown. lies cross-wise of the tank. the pipes 7l running longitudinally of the same. .\t their outer ends the pipes 7 arc closed. liest hy welding so as to avoid joints: and they are lett sulliciently t'ree to expand and contract longitudinally. They are held from longitudinal movement hodily hy their connection with the header c: which is fastened to thc tank hottom: and transverse motion ot' them is prevented l attachment to cross-hars fl. also secured to che tank hottom. liach pipe is lield h va loop c whose ends are fastened to the corresponding cross-hal' (Fig. Jl).

rl`he header c has a flanged hase. which at f. intermediate the flange f/ and the hody of the header. as compared with the latter. ol reduced area in horizontal section. This construction is advantageous. in that it. interposcs less ohstruction 'to the flow of the liquid contents ot' the tank to the draw-oil' pipe Il than a llanged hase of larger dimensions would do. and also it is helieved to lessen the stresses due to the alternate heat ings and coolings which result when steam is applied and cut o fl. Passages j for the inflow ot steam and Z' for the outflow of water are formed iu this hase. within the circle ot rivets hy which the header c is Jfastened to the tank bottom., There is. therefore, no danger of letting water into the oil in the tank by leakage at those places where l sist the shocks to which the car is exposed in running and in coupling. A tight joint around `the edge of the flange is made by calking.` As shown, the arms of the header c project from the base on opposite sides of the latter. 4

The header is shown as divided into two chambers by means of the partition m parallel with the flange g of the base f and transverse to the passages j Zr in said base. rl`his partition m forms the floor of one chamber and a part of the roof of the other chamber. The passage/f. communicates by means of the latter chamber with the pipes b on opposite sides of the header. Asshown in Fig. 5, the horizont-al partition m slopes downward toward the passage j; so that any condensation in the overlying chamber will lowtoward said passage j; which opens into said overlying chamber. rl'he chambers are each provided with tlireaded openings; which openings are'ot different diameters and are placed a small hole r behind each larger ones, but ecce'ntric with reference' thereto. As shown, the front and rear 'walls of the upper chamber (see Fig. 4) opposite the openings a are cui-red inward, so that .spaces are there shown (see also lfigs. l and 6) between the walls in which the openings r are formed and those in which the' openings,l are located. such spaces constituting in ell'ect extensions upward of the lower chamber. The larger holes receive the ends' of pipes L. which are screwed fast therein, best inclined so as to drain toward the header. The smaller holes receive the ends of pipes n, which are inclosed within pipes and are open at their outer ends within the latter and which are best inclined to drain away from the header.

At y is shown a nipple for attachment of a pipe (not shown and not ordinarily a part of the car) for connection with a source of steam t'or heating. pipc for the water ot' condensation.

ln use the tank a is filled with the liquid to be transported. As this would be in a fluid condition, the pipes l; can be left empty and unconnected with as0urce of steam. In transportation it would not be -ncccssary to keep tho liquid fluid. llut, of

coursc. tonnel-tion with a source of steam could be made at cithcr or both of these times, if dcsircd. empty the tank ofe its contents. the nipple 71 is connectwi with a steam supply pipe. The steam flows through passage j] .into the uppcr chamber and is delivered by the small pipes n, hito the far ends of the pipes 7;. lil

these the stcam conde-uses in imparting heat At l/ is shown a drain therein a header,

When it is desired tol to the contents of tank a by conduction through the walls of pipes b; and the water of condensation flows back to the header c and is discharged by pipe q; with which latter a pipe leading'to anyde-sired place mav be connected. 0n account of the inclination of the pipes I; and a, and the connection of the passages j and l.' with the bottoms of their corresponding chambers, no water need stand in the heating apparatus to be a source of danger by freezing therein.
