TANK-CAR.
Specification of Letters Patent.
Patented July 15, 1913.
Application filed January 22. 1912. Serial No. 672,524.
T 0 all whom it may concern:
Be it known that I, Cass L. KnNNIoo'r'r, of Chicago Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tank- (lars, of which the following is a specification.
. My invention'relates to railway rolling stock and has particular reference to a novel construction of tank car.
Tank cars are at present employed for handling a variety of liquids and are frequently employed in handling hot liquids,
that to say, substances which harden at normal temperatures but which melt or fuse at a temperature around the boiling point ofgvater, for instance lard and similar substa1icesf-"The practice in the handling of such substances is to allow the same to flow into the tank while in hot or fluid condi tion. Shortly thereafter the material becomes set and to remove the same steam is injected into the tank by means of a'series of pipes thus heating the material until it becomes tlu' 'l when it'may be removed. It will readily be seen that this involves a material change in temperature and will thus cause considerable expansion and contraction of the tank. The extreme expansion may sometimes amount to as much as one inch for the entire length of the tank. It has heretofore been common to mount the tank on a rigid underframe, the tank rest ing on saddles and restrained from endwise movement by means of head blocks at the ends of the tank. It is apparent that even though the tank and head blocks may be fitted nicely when the car is'completed the expansion of the tank due to an extreme temperature will tend to displace the head blocks and when the tank is cooled leave a space between the end of the tank and the blocks. As soon as the car goes on the road and is subjected to the shocks of bufiing and certain constructions have been atented with the idea of avoid' this itliculty, that is, fastening the ta' to the under frame at its tcentral portion by riveting or ing e by means of an interlocking connection.
This necessitates a. strong and rigid under- 1 frame extending-throughout the length of i ber, which member is riveted securely to the bottom plate of the tank, draft sills'which are rigidly securedtothe saddles or body bolsters, then riveting orbolting the shock resisting member to the draft sills. This channel-shaped shock resisting member is in a sense a part ofthe tank and the heat will be transferred thereto causing expansion and contraction with the tank.. Any expansion of the tank as a whole will exert n0 strain with relation to the trucks inas much as the trucks will merely be placed farther apart under expansion anddrawn closer together under contraction. i
The objects of my invention are there fore: 1st, to provide means for taking care of expansion and contraction without the necessity of employing head blocks and double riveting the end plates,'and 2nd, to eliminate the weight of a continuous underframe.
My invention Will be more readily under stood by reference to the accompanying drawings, wherein,
Figure 1 is a side elevation of a tank car constructed in accordance with my inven tion; Fig. 2 is a bottom plan view thereof with the trucks and draft sills removed: Fig. 3 is a transverse fragmentary section on a line contiguous to one of the body bolsters or saddles, and Fig. 4 is an eularged fragmentary longitudinal section through the center of the car, the truck beiminated.
Referring more particularly to the drawings it will be seen that a tank of ordinary construction is mounted upon trucks 10.
there being interposed between the trucks and .the tank body bolsters or sadd l These saddles are preferably formed )1 two castings, the channels 12, forming the t sills, separating the two castings as in Fig. 3. The castings and the draft are tied at the bottom by means of a pl te 13, which plate carries the center plate. resting on a truck bolster l5. Secured to the continuous bottom plate 16 of the tank at either end of the car is a channel 17, the flanges being turned downward and resting upon the flanges of the draft sills 12. These 7 channels 17 act as shock distributing mem-j-r hers, the blows "received by the draft sills being transferred to the plate 17, and by them distributed to the body of the car. In order to secure the two flanges together I provide angles 18, which angles are riveted to'the flanges of the channel 17 and riveted or bolted to the flanges of the channels 12. As shownin Figs. 1, 2 and 3, this channel shaped member .17 fits the bottom plate 16 treme expansion and contraction of the tank without possibility of the shearing of any rivets and by the same means eliminate the cost and weight of a heavy underframe.
While I have'shown the channel-shaped shock-resisting members as extending a portion"of the length of the car it will be apparent that variations ma be made in this V as well as otherdetails, a 1 without departfrom the spirit of my invention.
I claim: 7
1. In a tank car, the combination of a tank, trucks beneath each end of the tank, a channel-shaped shock-distributing plate secured to the tank at each end, and draft sills secured to said shock-s distributing plates, substantially as described.
2. In a tank car, the combination of a tank, trucks beneath each endof the tank, a shock distributing plate wardly extending flanges, said plates bein secured to the lower face of the tank an extending longitudinally thereof over a limited space at the ends of the car, and draft sills secured to said tank through the depending flanges of said, shock-distributing plates, substantiall as described.
3. In a tank car, t e combination of a tank, trucks beneath each end of said tank, shock-distributing plates of channel shape the flanges thereof extendin downwardly, each of said plates being 0% a length less than one'half the length of the car, said plates being secured to said tank at the ends thereof, and draft sills secured to said tank through the medium of the flanges of said distributing plates, substantially as described.
