Be it known thatI, MARK A. DEES, a citi zen-of the United States, residing at St. Louis,-

in the State of Missouri, have invented certain new and usefullmprovements in Freight- Cars, of which the following is a specification,

.reference being 'had to theaccompanyng drawings, forming part thereof.' y

My invention relatesto freight-cars of the 1o class generally used for transporting petroleum and other liquids or grain from place to place, such cars being commonly known as tank'or oil cars. i

yOne-object 'of my invention is to improve r 5 the construction of an oil or tank car,the body of which is ordinarily an elongated cylinder, for the purpose of increasing its carrying capacity without raising its centerof gravity, lengthening its wheel-base, or the distance bezo tween couplers. In accomplishing this result I make the body or cylindrical portion of the car of enlarged diameter and increase its I' length nntiliit extends from coupler to coup-Y ler. The tank or body of the car thus changed is supported onA .holsters on' the trucks yas low as possible', bringing the footboard on top of i the tank to the level of that of the ordinary.;

y, box freight-car andthe bottom of the tank below the line of draft. 3o about nine feet in diameter, if mounted on a platform or in any other known manner to permit the placing of-.the draft mechanism beneath it elevates the car and raises its cen-v ter of gravity so high that the danger 'of de- 3 5 railment and overtnrningon roundingcurves is great. An increased height also endan gers the car by its liability to strike low bridges, tunnels, &c. ,l overcome this`difticulty by lowering the supports of the tank, as above 4o stated, and placing the sills vand draft mechanism within the tank, but separated from its contents `by-means of a duid-tight fioor or` partition.

A further-featnre of my invention consists in placing within the cylindrical body of the `car a truss or open frame lrunning centrally therethrough from end toend for the purpose of increasing its strength and rigidity.

. Referring to the drawings, Figure 1 is a lon- 5o gitudinal section through a car constructed in accordance ywith the principles of my invention. Fig. 2 is a cross-section thereof on L truck-bolster a.

The tank, which is Y the line 2 2. Fig. 3 is a horizontal sectionon thei'ine 3 3 of Fig. l. Fig. 4 shows a `modiied formv of the coupling mechanism; and Figs.P 5 and 6 are cross-sections therethrough 'on the lines 55 and 6 6, respectively. Fig..

7 is a view of a modified form of the floor.

Similar reference-letters indicate similar parts in the respective figures. A and B represent' two car-trucks of ordif l nary construction supporting a cylindrical tank or body C. Between the wheels of each truck and forming a part: thereofgis the usual Tothe under side of the tank or body lC, near each end, is bolted a crescent-shapedbody-bolster c, each of which rests onone of the truck-holsters a and is pivotally connected thereto by a king-bolt b.v Side bearings d are applied to the trucks and tanker car body as usual.` Y Q The cylindrical body or tank C, as it will be hereinafter designated, is closed at each end by a head D, made duid-tight in any approved manner. 1Within the tank and bolted 75 Extending from' the floor F to the T-beam E 8o 'in the longitudinal center of the tank 'are a .Series of nprights' or columns Gwhich, with the truss-rods H, reachingdiagonally between the uprights and thezeuds of the car, ,form a y tight and rigid truss-frame for strengthening the tank and retaining itin proper shape. turnlinckle Iris shown'on one' of the truss# rods for" adjusting its" tension. Y Similar buckles may be placed on all the rods, if desired. I p

A tank constructed as above will be ver-y strong and rigid and well adapted to resist all strains to which it may b e subjected, especially such as areproduced by supporti ng the tank near the ends only. g

Within the-tank, but beneath the floor F,

' are placed two longitudinal channel beams or sills J, projecting va short distance through the head D of the tank and spaced suiciently I far-apart to permit the` application oit'l draft roo mechanism K between them.. Thechannelbeams J, which are placed with their web portions in vertical position, are riveted through their lower flanges to the bottom ofthe tank, d

their upper llanges being connected to each other by ahorizontal plate L, riveted to the flanges and running the length of the car immediately below the door F. This construction forms a strong box-girder, aording additional strength tothe tank and a central support for the oor F, which, however, is not connected to the channel-beams .I or plate L. By supporting the tank C on the trucks A B in the manner described its height is reduced to such an extent that notwithstanding its large diameter the footboard W on the top of the tank willrbe' substantially ona level with the roofs of adjoining box-cars. The bottom also is low enough topermit the line of draft to pass ywithin the tank, as shown and described. I

v Instead of using a straight plate for the floor F it may be of the shape shown in Fig. 7 and by dotted lines inv Figs. 2 and 5 to closely embrace the box-girder formed by the channel-beams J, 'plate L, and bottom of the tank.

Ordinary draft-rigging, such as that. shown in Figs. l and 3,4 will usually be employed to couple the cars togethergbut undersome circumstances the through or continuous drawb'ar (illustrated in Figs. 4, 5, andd) may be desired. In the continuous draft rigging here' represented the channel-beams J J are not rivetedto the tank, but are connected at their tops by a continuous plate L and at their bottoms by two plates M' M', their inner ends being separated a short distance at the center of the tank. The bottom plates MM' rest and are'adapted to slide upon the bottom of the tank. .A casting O', riveted to the bottom ofthe tank at its center, extends upwardly betweengthe plates M' M' and -has alongitudinally-directed hole, through which a rod P' may freely slide, the ends/of the rod P' being` secured to blocksQ', which latter are in turn fastened to the beams J J above the inner ends of the plates M' M'. ,A space is thus left on each side of the casting O' and between it and one of thel blocks Q', Within' which spaces are spiral springs -R' R', preferably surrounding the `rod P', to serve as bu'ffers. The continuous draw bar thus constructed is capable of a slight longitudinal movement under working conditions to lessen the force of shock and jar, which is conveyed toy the springs and there absorbed. Angle-pieces S' are rivetedto the tank C and floor `F to guide the draft mechanismv and retain it in its proper position. These angle- I pieces are dispensed with when the Iiloor is made as represented in F ig.|`7.

I do not restrict myself tothe exa'ctdetails of construction, combination, and arrangemeut herein set forth, it being obvious that vminor variations thereof not involving the exercise of invention maybe made bythe skilled mechanic, and'such departures from what is herein described and claimed not-involving' invention I consider as within the scope and terms of my claims.
