To all whom it may concern Be it known that I,- lVILLiAM P. BETTER- n'our, a citizen of the United States. residing at Bettendorf, in the county of Scott and State of Iowa, have invented new and useful Improvements in Means for Cushioning the Bodies of Railway-Cars; of which the following is a full, clear, and exact description.

My invention relates to railway cars, and more particularly to tank-cars.

The principal object of my invention is to modify the strain on railway car when it is subjected to a sudden pull or to a violent butting contact, and to neutralize the etl'ect oi a shifting load, as exemplified by the movement of the liquid contents of a tank car when traveling on a poorly graded or crooked track. i

A further object of my. invention. is to flexibly connect the body of said ear to-the body bolster without: ailecting the relation of the latter to the underframe of the same. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings :Figure 1 is a side elc-.

vation of one end oi a tank-car embodying Fig. 2is a longitudinal vertical section of the opposite end portion thereof. through the lower portion of the same, taken-in such a plane as to show a side elevation of the bolsters. Fig. 4 is a transverse vertical section, through the lower portion of the same taken on dotted line 4 4. Fig. 11 Fig. 5 is a plan View of the broken away central portion of the bodybolster. Fig. 6 is a horizontal section thereof taken on broken line 6, 6, Fig. 2. Fig. 7 is a vertical longitudinal section taken on dotted line 7-7, Fig, 8, drawnto a larger scale and showing parts of the cushioning mechanism in longitudinal section. Fig. 8 is a plan of one end of the undert'raine having the tank and other parts removed.

For the purpose of more conveniently explaining my invention, I have confined its application to a tank-car;

Fig. is a transverse section,

mg or i i I I In the drawings tank, that is supported in the transverse plane ofthebody-bolster by means of saddles B, each consisting of a suitable castthe vertical planes of the car-wheels, and

A represents a suitable plate extending transversely between I Mar. 24, 1914..

having its upper surface concaved to con-' tor-in to theeurvature of said tank, which i seated therein. At its ends, this saddle is provided with rudimentary feet consisting of dowmvardlv extending hollow boxes the plane of the under-surface of the :ildS of which is horizontal. The undersurfaces of these boxes are provided with two or more that are transverse to the axis of hetank, and rest upon rollers C whiclrlatter are of corresponding diameters when the car is stationary will be in a state of rest at the inverted bottom o1 said corrugations. These rollers are seated in corrugations c. c, in

corresponding corrugations if 05 the adjacent ends of cast metal b0dy-bol-- sters D, the outer ends of which preferably terminate in the same vertical plane as the ends of the saddle, but are provided with integral brackets (I that extend in a longi-, tudinally upward direction to and support the running-board E of the car which is riveted thereto and extends from end to end of the car. At its center of length the bodybolster, is provided with a transverse pocket F which extends lengthwise the car in the vertical plane of the king-bolt, Z, and is adapted to contain a coiled springG placed therein, the ends of which bear against follower-plates f, f, located at each end of said pocket. The ends of thepocket are provided with vertically elongated openings y, and the ends of plungers HQ H, extend longitudinally. through these openings and engage the follower-plates. The shanks of these plungers enter suitable horizontal sockets. 11, made in heads, Lthat are made integral with and depend down from the Q i LGQLldS tudinal movement independent of the heads, I, by means. of the set screws 1c.

The corrugations c, c, of the bolsters, correspond to the corrugations a of the saddle, and; when the car is at rest the ridges between these corrugations and the bottoms thereof will be in the same vertical trans verse planes. Now when the car is in' mo tion and it is subjected to either a pulling or a buiiing strain the momentum of the tank will cause the rollers C, (3.. to roll up the incline sides of the corrugations and litt the tank, and when this impulse of the tank is spent, its weight will cause the rolls to gravitate to the'b'ottom of the corrugations and return to a state of rest therein. At the same time this action of the rollers'() is taking place, the plunger H onsthe side of the bolster opposite thattoward'whichthe tank is moving will, throu h the medium of the follower f-engage an i which latter resists and absorbs the shock of the thrust, and when it expands, restores the plungeis and the tank to their normal posi-- tions. The openings 9 through which the ends of the lungers H extend in order to engage the ollowers f, are widened verticallv to accommodate the upwardmoveinent .of the tank, andthe'saddle due to the action of the rollers C, C. If, however, these rollers C, were dispensed with the opening g would only be of sufiicient diameter to permit of the passage of the plungers.

The underside of holster D. at its center of length, is provided with a male centering plate which isseated in the female centeringplate of truck-bolster L, which latter is bellied down at its center oflcngth to enable the center of gravity of the tank to be lowered as much as possible. and the ends oi this truck-bolster L are supported by springsresting upon the sill of asuitable bolster opening of the side-frames of the trucks,

substantially as shown and described in Letters- Patent of the United States granted to mev October 6. 1903. No. 740,617.

The rear side of the body-bolster D is provided with wings N the inner vertical surfaces of which are patiallel and are arranged substantially equil distant from the vertical plane of the axispf the tank. and their upper flanges are bent outward and they are otherwise constriicted so as to afford incans to which tlie lianges of a horizontally disposed I-beam center sill M can bcsccured by means otrivcts or otherwise. This horizontally disposed renter-sill extends longitudinallvfrom the fbodv-bolstcr at one end of the car. and I prcf r to bend the upper flanges of this I- bcain center-sill outward, to accommodate and to permit the tank to occupy as low a position as possible and to avoid the shearcompress spring G;

single I beam 1 ing strain on the rivets used to secure their ends to wings N.

The front side of the body-bolster is provided with forwardly projecting draft-sill extensions 0, O, on each side of the vertical plane of the axis of the tank. These extensions are, preferably, I-shapcd in cross section and converge toward each other until they reach a point slightly beyond the transverse vertical plane of the end of the tank "car, where they bend upward. Ii -om this ing sides parallel to each other, and provided with suitable stop-lugs 0 for the followerplatcs of the draft-rigging (not shown), and have their ends connected by crossincmbers 1') both above and below the drawbar opening. The usual floating end-sills P are mounted transversely upon and carried by these dra fT-Slll extensions 0 at their outer raised ends, as shown in dotted lines in Fig. 8 of the drawings. I

I do not wish to be connncd to the cushioning-springs being located in the bolsters, as they can, if desired, be located at the center of length of the car, substantially as shown in a coin anion application for a modified form 0 my invention 33. 1910, Serial Number 562,922, but desire to be understood as claiming as my invention the broad idea of both features, as well as the cushioning of the car-body or tank to limit the extent of the longitudinal movement of the same. If desired these two features can be used ,in combination or separately.

What I claim as new is Q 1. In a railway car. an underframe comprising suitable end-sills,-body-bolsters, and a center-sill the ends of which are connected to said body-holsters, car trucks, a longitudinally arranged cushioning device carried directly by said bolsters, a 'car-body adapted to have a slight longitudinal moveincnt independent of the underframe. and means connected to and projecting from said car-body adjacent said bolsters that are adapted to engage and compress said cushioning device.
