WILLIAM I. BETENDORF, OF DAVENPORT, IOIYA.

TANK-CAR.

SPECIFICATION forming part of Letters Patent No' 788,016, dated April 25, 1905.

Application filed March 30, 1904. Serial No. 200,830.

lie it known that I, WILLIAM P. Bn'r'rnxnoun, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in 'Iank-Cars, of which the following is a full, clear, and exact description.

Tank-cars now in use are so constructed that the draft-rigging and the line of draft therethrough are below the rank. Considering the side wash of the oil or other liquid contents of the tank while the car is in motion, the danger of the car turning over because of the great centrifugal force when rounding curves or jumping the tracks is a source of anxiety to railroad men.

The object of my invention is to so construct the car as to lower the center of gravity of the tank, and thus minimize this danger. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings. Figure 1 is a longitudinal central section of a tank-car embodying my invention. Fig. 2 is a longitudinal central section of one of the said tank-cars, drawn to a larger scale and taken on dotted line 2 2, Fig. 3, looking in the direction indicated by the arrows. Fig. 3 isan end view of the lower portion of one end of the tank, drawn to a still larger scale. Fig. t is a transverse section taken on dotted line *1 ".l:, Fig. 2, looking in the direction indicated by the arrows, buton a slightly larger scale. Fig. 5 is a plan view of the under side of the tank, illustrating the manner in which it is prepared to receive my improvements. Fig. 6 is an end view of the same. Fig. 7 is a transverse section of the tank, illustrating a modified construction of the butfer-colunm.

Referring to the drawings, A represents a suitable tank which is provided with a longitu linally-elongated rectangular opening a in each end, which extends from an opening of about the same width in the heads thereof back therefrom past the transverse plane of the truclvpivot. Placed in these openings (1 I) is an inverted channel shaped draft rigging frame B, which is preferably cast in one piece of metal and has its lower longitudinal edges provided with lateral flanges e c, that lap against the under side of the shell of the tank adjacent to said opening and are riveted or otherwise securely fastened thereto. The forward ends of the rigging-frame B, which exl tend through opening in the tank, are also provided with lateral flanges that form a shield C, which is riveted or otherwise suitably secured to the outer surface of the head of the tank and greatly strengthens and reinforces the same. The end .r of the channeled portion of the rigging-frame opposite the shield U terminates just before it reaches the center plate and is closed, and between this closed end .11 and the head of the tank said frame is provided on its vertical sides with in ardly-projecting vertical stops 1/4, that are engaged by f at the entrance of the channel of the riggingframe and under the yoke thereof by a suitable cross-frame E, whose downturned side edges are bolted or riveted to the sides of the channel of frame B, which latter has its lower edges dropped slightly at this point.

The rigging-frame B extends back from its closed end a' in a plane corresponding to that of the shell of the tank, and this extension passes over the truck-bolster and has the body center-plate (/I suitably secured to the under side thereof. The rear edge of this extension has cast in one piece therewith and arising therefrom a lmliing-hcad F, consisting, preferably, of a solid block of metal of about the same height and width as the channeled portion of the rigging-frame, to which it is connected by a centrally-located longitudinallydisposed vertical web 7/. The vertical side of this head farthest from the channeled portion of frame B is provided with a longitudinal central opening, and secured in the opening of the head F of the draft-rigging frame at each end of the tank is a tubular bultingcolmnn. The ollice of this butting-column is to take up the strain of the pull of the draw-bar and the shock of the humping of the cars and to relieve the shell of the tank therefrom and in addition to serve as a steam-chamber to keep the liquid contents of the tank warm, particularly in cold weather. Steam is introduced into column G through vertical inletports H, made in said heads F, to the lower ends of which suitable steam-pipes J are connected, substantially as shown. The bufiingcolumn is preferably of such dimensions that the necessity for the presence of other steampipes in the tank is dispensed with, and it forms a continuous connection between the draftrigging frame and practically takes the place of center sills. If desired, the buffing-column could between the heads F be provided with a series of looped pipe connections I, whose ends, spider fashion, would radiate therefrom and which between their ends would run substantially parallel with said column. Such an arrangement of steam pipes might be deemed desirable in cold climates; but I do not desire to be confined to their use nor to the exact location of the buffing-column as shown.

In the construction of my improved car the connections between the draft-rigging frame B and the tank A are made as tight as possible to prevent the leakage of the contents of the car. Such leakage may be further guarded against by partitioning off the lower portion of the ends of the tank in which the draft-rigging frames are secured, so that an empty chamber surrounds the same. This I accomplish by a sheet-metal cover K, that arches over the rigging-frame B, as shown in Figs. 2 and 4 of the drawings, and has its end farthest from the head of the tank bent vertically down and clamped against the adjacent vertical surface of the buffing-head F by the circumferential flange Z1, projecting from the buffing-column near their ends. The edges of this cover K bearing against the inner surface of the head of the tank the longitudinal edges of said cover. and the transverse edges of the end of the same contiguous to the buffing-head are all flanged and riveted or otherwise suitably secured to the shell of said tank. The construction of the draft-rigging frame may be modified to suit the type or style of draft-rigging set forth in the specifications of the purchaser and may be so designed and made as to allow the horizontal plane of said frame to be relatively higher or lower in said tank than as shown. All such changes I desire to be considered as contemplated within the spirit of my invention, the object of which, briefly stated, is to lower the center of gravity of the tank, and by thus reducing the height of the triangle, of which the center of gravity is the apex and the ball of the rails of the track the lower angles, broaden the base upon which the car is supported and give greater stability to the same when in motion.
