To all whom it may concern:

Be it known that I, ALLEN EDWARD Os-- the accompanying drawings, which illustrate the preferred form of the invention,

though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that the various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 isa side elevational view of a tank car constructed in accordance withmy invention, parts of the underframe being broken away and illustrated diagrammatically. Fig. 2 is an enlarged detail central longitudinal sectional view of one of the end portions of the underframe structure shown in Fig. 1. Fig. 3 is a top plan view of the parts shown in Fig.

2, the tank being removed.

The invention relates to means for anchoring independently constructed bodies of cars against longitudinal, or rather excessive longitudinal, movement relative to the sustain ing underframing thereof, at the same time so constructing and combining the respective parts of the undcrframc and the car body and the anchor for the car body as to permit said body to be readily removable from said under-framefor repairs or renewal.

The int ention is particularly applicable to tank cars, in which a cylindrical metal tank is mounted on an underframe comprising principal center sills adapted to resist buffing stresses incident to service conditions, YlllCll sills are spaced apart beyond the bolsters to receive between them standard types of draft rigging now approved by the Master Car Builders Association.

The invention also relates to railway cars in general, and more particularly to cars for carrying a load'movable elatively to the car underframing, and in some of its details has quantities of fluid, termed tank cars Among other objects of my present invention are the provision of an improved support for the ends of the body or tank, the provision of improved yieldingly resistant abutments for adequately holding the tank 1n place and at the same time compensating for the hammer like blows of the liquid in stopping the car, to the end that the tank may neither become loosened from the frammg, nor the framing itself disturbed by the blows of the tank; to provide means whereby the springs, frictional members, or other shock absorbing and yieldingly resistant members of the draft gear rigging may be utilized and further proportionately compensate for the movement of the tank; to provide an improved means for mounting the tank relatively to the framing to the end that it may be most readily removed therefrom, together with such other objects as may hereinafter appear.

The principal object sought to be attained is the simplification of the construction of such cars in so far as the anchoring against longitudinal movement is concerned.

In the drawings the invcrtion is illustrated as applied to a tank car to which class of cars it is particularly adapted. Heret'ofore it has been customary to add one or more elements to the structure of tank cars in order to prevent movement of the tank relative to the underframe; either headblocks have been fixed. to the underframe and disposed for engaging the opposite ends of the tank, or fixtures of various-kinds have been attached to the tank and underframe intermediate the ends of the tank, for accomplishing the same result. lVith the present invention, however, 'all necessity for these additional elements is eliminated.

In the common construction of tank cars the draft gear is supported between apair of draft sills and the forward and rear followers of said draft gear are fitted between and limited in their longitudinal movements by front and rear follower stop's. These follower stops have been commonly manufactured as independent members and have been riveted to the opposing faces of the draft sills. Heret-oforc they have had practically no other function than that of limiting the movement of the followers of the draft gear.

This invention provides that the rear fullower stops, that is, the follower stops nearest the bolsters, shall extend between the I j frame.

' ticallyfill the open space between the 'vent transverse movement or tippin draft sills and abut the rear follower of the draft gear.

tank stop castings which abut the rear followers of the draft gear and thus become an effectual means for limiting the longitudinal movement of the tank relative to the under- Such tank stop castings. connected to the tank are, therefore, not connected to the underframe in any way, but, when the tankis in position they project into their appropriate positions between the draft sills and between the bolsters and the adjacent rear followers. The members depending from the tank are of such section as to rapra t sills, and extend downwardly some distance below the top plane of such sills, as will be noted in Fig. :2, thereby providing an anchor at each end of the car well adapted to preof the tank on its underframe as well as imiting longitudinal movement of the tank. The two bolsters with the intermediate portions of the underframe form practically a single projectionor abutment between the two appendages from the tank. If no provision is made for the engagement with the bolster,

that is to say, if there be an open space between said tankstop castings and the adjacent side of the bolster, it will be apparent that the tank will be allowed a limited longitudinal movement and that, through the contact ofthe tank stop castings with the rear followers of the draft gears, the spring and friction devices comprising thedraft. gears will be utilized to cushion such movement and to prevent an excessive movement. Even when the space is intended to be eliminated and the follower stops are brought, as near as practicable to the bolsters, the springs of the draft gears will serve to cushion what slight-movement may be present, should any occur through imperfect workmanship in assembling the parts of the car.

It will be understood that the invention is not limited to use in connection with tank cars, but is equally well adapted to use in connection with any and all classes of cars wherein the body portion thereof is independent of the underframe and subject to movement relative thereto.

' Referring to the drawings forming part of this specification, the numeral 1 indicates the tank,22 the draft sills; 3 the bolster, 4 the draft gear as a whole; and it will be noted that'for the purpose of this disclosure there has been illustrated diagrammatically the well-known type of Cardwell draft gear wherein a draw bar 22 carrying a coupler head 23 has rigidly connected thereto a yoke 24., within which are mounted front and rear followers 25 and 26, disposed between which are the usual wedge blocks'operablymounted upon the transversely disposed spring rod 31 on which are carried springs 32 and 33 secured thereon by spring caps as indicated at 34. There is also disclosed particularly in Fig. 3 the front follower stops 5 attached to the draft sills in the conventional way, and the tank stop castings or rear follower stops 6 attached to the underside of'the tank and forming anchors therefor.

In adapting the rear follower stops to their new functions, as hereinbefore set forth, it has been found desirable to form 'them into single castings, each comprising a top plate as 9 shaped to fit the under side of the tank or other form of car body, so as to be securely and rigidly fastened thereto one near each end. Integral with and depending from these top plates are suitably ribbed and otherwise reinforced members which form the rear stops 6 constituting the tank anchors. Said stops are disposed in pairs, one of each pair adjacent the inner'face" of each of the draft sills 2, and their forward faces are adapted to be engaged by the rear follower of the draft gear in precisely the same manner as if they were fixed to the draft sills as heretofore, there beinga clear space left between the stops 6 for the draft yoke 24 to travel from its normal position toward the bolster.

When a car as ordinarily constructed is subjected to one of the great variety of minor collisions to which cars of all classes are subjected, incident to the coupling of cars together and to other apparent causes, the shock being received first by the coupler and draft gear and then by the underframe, produces a tendency for the underframe to travel longitudinally from beneath the car body or tank. This tendency in the design illustrated herewith is overcome by the engagement of the draft gear with the stops or anchors 6 at both ends of the car as'is clearly apparent from the illustration Fig. 1. The shock received by the draft gear at the near end of the car, is transferred directly to the adjacent portion of the tank, through the engagement with the adjacent stop 6, thus effectually absorbing or neutralizing the tensile stresses to which the tank might otherwise be subject. It will be noted that the central portions of the bolsters are formed with extensions 5 projecting toward the end sills, and terminating in stop faces 77, somewhat beyond the normal line of the bolsters proper and being riveted to the draft sills, as shown in Fig. 2. This extension is adaptcd to provide a large rivet area for the rivet connection and permit the use of suitable riveting tools, as shown, these extensions 3 are preferably made hollow. It will be apparent from this disclosure that the stops 6 are designed to have no engagement with the bolsters, and with this construction a shock received at one end of the underframe be transferred didinal relative movement of the tank. This" duty devolves entirely upon the draft gears at opposite ends of the underframe. \Vlien a car is one of a train, a shock received at one end will tend to push the tank toward the opposite end of the underframe. This tendency, however, will be resisted by the engaginent of the draft gear at the opposite end of the car with the next succeeding car. This latter engagement will cause the draft gear at that end of the car to be compressed so as to exert a spring pressure against the adjacent stops 6 sufficient to overcome the pressure at the first mentioned end of the car and maintain the tank practically in a fixed relative position.
