Y '0 all whom it may concern Be it known that 1, JAMES HARVEY lVooo, Jr., a citizen of the United States, residing in the city, county, and State of New York, have invented or discovered certain new and useful Improvements in Railway-Cars, of which the following is a specification.

My invention relates to railway cars for both passenger and freight service, and contemplates,-as a general principle of car construction, a railway car consisting of two separate and distinct units,a car carriage or running gear, and a car body. Each unit is constructed independently of the other, and is so designed that any running gear of a given class or type may be used -with any car body of a corresponding class,

type, or capacity- To this end these two units are so designed as to permit of simple and quick removal of a'car body from a running gear, and of readily interchangeable usage of either with different running gears or with different bodies ofthesame respective types. The running gear embodies trucks, draft member, couplings, and

a-ll equipment and appliances (including air brakes which are not shown in the drawings) essential or incidental to the operation of a car as a train .unit. Heating, lighting and other equipment pertaining to the car body exclusively. is attached to the body. Each unit will be designed for its particular functions. The car body will be designed for its load, without the necessity of considering its strength in relation to its use as part of a train unit, as the running gear will be designed to meet that function,

in connection with Therefore the position of the car body,

- whether light or heavy, in the make-up of a train, becomes of minor consequence since it 15 not a train resistance unit and its running gear will be of proper minimum which will aiford greater safety to passen-' gers, to freight, and to the car body itself; which is less liable to be damaged under all contingencies of its operatlon; that is cheaper in first cost than under presentmethods of construction;

that is expenits other functions.

sive to maintain and to operate than cars for slmilar usesas at present constructed; that affords greater utility, increases the scope or use of cars, and provides other advantages not heretofore possible; that does not alter the substantial constants of height of coupler and car floor above the rails; and that does not resolve the downward or top-of-rail pressure into a rigidhorizontal or rail-spreading force.

Other objects and advantages of my invention and the manner in which I realize them will be obviousfrom an explanation and from the following description of the embodiment which I have chosen to illustrate it as shown in the drawings accompanying and forming a part of this specification.

Referring to the drawings: Figure 1 is a vertical section of a car embodying my.

invention, taken on the line 1-1, Fig. 2, looking in the direct-ion of -the arrow,'the car body being indicated by dotand dash lines; Fig. 2 is a plan view similar to Fig; 1 with car body removed, and with the combination body support or bearing and longitudinal bufier device taken on the line 22, Fig. 1, looking in the direct-ion of the arrows; Fig. 3 is anenlarged detail in vertical section of the body bearing and longitudinal buffer device looking in a direction at right angles to Figs. 1 and '2; Fig. 4 is a side elevation of a car. showing several of the combination body bearing and longitudinal buffer devices referred to under Fig. 2 and Fig. 3, and showing the vertical buffer members extended below thedraft memher and supporting at their lower ends a detachable truss which in turn supports battery boxes or other usual car floor appendages; Fig. 5 is an end elevation of a car body indicating methods of lifting same from running gear; "Fig. 6 is a side elevation of a car truck; Fig. 7 is a similar elevation partly in section; Fig. 8 is a vertical section on line 8--8 of Fig. 7, looking inposes of illustration, Fig. libeing takenon Iline .11--.1 1,; Fig. .12, ;.and Fig. .112 .being too shown partly in'elevation; Fig. 13 is a view similar to Fig. 11 showing a construction similar in principle to that shown in Fig. 11, but with structural changes and comprising the preferred embodiment of my invention as applied to trucks for freight cars.

Referring in detail to the drawings, the

fundamental construction of the running gear is similar to that in ordinary use, consisting in the main of wheels 1, axles 2, wheel pedestals 3, truck frame comprising side pieces 4 and end pieces 5, equalizing bars 6, and springs 7.

In ordinary car construct-ion, the car body has heavy longitudinal draft beams incorporated therein as part of its necessary structure. In my invention these draft beams, indicated by reference numerals 8, are mounted on the trucks, separately from the car body, and constitute part of the running gear. As to form, the draft member is shown depressed at trucks after clearing axles for the purpose of keeping the car body pivot as near its position in present construction as possible. However, this depression is designed to be so slight as not to subject the draft member to jar or vibration upon solid impact and it is obvious that the draft member may be of a straight line construction from end to end-by raising the truck bolster. Also the draft member shown in the drawings is of two beam laterally reinforced construction, it being assumed,.however, as obvious, that this draft member may be of any approved construction. The draft beams are provided with end braces 9 and end pieces 10 and have mounted thereon draft rigging 10 and conplings 10 In the construction shown in Figs. 1, 2, 6, 7, and 8, the' draft members are mounted on each truck by springs and by a universal bearing device constructed as follows: Rigidly secured to the bottom of the wheel pedestals 3 are lower side pieces 4 on which is mounted a column seat 11, having thereon a vertical column 12. On this column is slidably mounted a collar 13, maintained normally in any desired position thereon by springs 14. Collar 13 is provided with collar trunnions 15 on which is pivoted a yoke 16 having yoke trunnions 17 which fit in bearings 18 secured to draft beams 8. By this construction the draft beams are maintained and their weight supported directlyby springs 14 and are indirectly supported on the equalizing bars by a downward pull instead of downward pressure on the equalizing bar springs, thus permitting lighter and more sensitive spring to be used between the car body and the trucks. This construction, embodying a form of universal bearing, also insures full, free, and easy truckplay withinthe limits of established requirements and without ex-' cess or loose flexibility, facilitating a true spiral movement of the car body in rounding curves, particularly banked curves.

The truck is adapted to receive the weight of the car body on a truck bolster 19, which rests on bolster springs 20, supported on a seat member 21, connected by links 22, with transoms 23, rigidly attached to side pieces 4 of the truck frame. The bolster is confined between upper transo'mvmembers 23,

as in ordinary construction, which transmit the longitudinal thrust on same to upper side frame 4. Truck .bolster 19 is provided with a central bolster pivot 24 having a conical shaped head fitting within the top of column 12, thereby permitting lateral tilt of the truck bolster 19 when bolster springs 20 are compressed unequally, and this bol ster pivot is so proportioned at its greatest diameter as to permit of vertical movement, without jamming, in the column 12 when the bolster springs are compressed. The top of column 12 fits within a rectangular recess 25 on the under side of the truck bolster, and the upper end of. the column is slightly flattened on the two opposite sides facing the ends of the car body in order to support'this end of. the column by pres sure against the straight sides of the recess and at the same time. permit dip of the truck bolster when the bolster springs are compressed unequally. 0n the top of the truck bolster 19, in the center, is provided a bearing seat 26 in which fits a pedestal 27 having yoke arms 28 (Fig. 7 The pedestal is held in position by pin 29 extending through said pedestal and into a socket provided therefor in the top of the truck bolster 19,. which socket extends downward into bolster pivot 24 to a sufficient extent to accomplish its purpose of preventing displacement of the parts. This construction affords a firm and a non-wobbling seat for the center bearing construction. The yoke arms 28 are provided with a bearing bolt 30 on which is slidably mounted a block 31 provided with block trunnions 32 (Fig. 8) and yieldably maintained in the center of the yoke by yoke springs 33 F igi7). Pin 29 is placed in position before bearing belt 30 is mounted in yoke arms 28.

Car body 37, shown in dot and dash lines (Fig. 1), detachably engages the center construction of truck bolster 19 by means of a body bolster 34 (Fig. 8) secured to the car body and having an arched section 35 provided with open end bearing sockets 36 adapted to fit over block trunnions 32. The sides of the car body are supported on the truck bolster 19 by means of longitudinal bearing bars 38, which are vertically movable and are held in guide sockets 39 secured to the bottom 'of the car body. Springs 40 are provided between each end of the longitudinal bearing bars 38 and the car bod to allow proper flexibility ofmovement truck and car body with respect to each other. An additional guide member 41 I secured to the car body is provided for the center of each longitudinal bearing bar 38.

The guiding sockets 39 retain the longitudinal bearing bar 38 in position when the car body is raised from the running gear, and

- the additional guide member 41 aids in resisting any twist of the longitudinal bearingbar. The obvious reverse of this construction would be to secure guide sockets, springs and bar to truck bolster so that the bearing bars would operate against suitable bearing surfaces on the car floor. frame.

A combination car support and longitudinal buffer device between the car body and draft member 8 is provided atvarious points. of the car length, according torequirements and advantages. One such device is shown in Figs. 1 and 2 and in some detail in Fig. 3, while Fig. 4 illustrates application of three of these devices between trucks; none being shown or suggested for points between ends of car and truck centers. A box-like construction is formed between draft beams 8, consisting of end members 42 secured to the draft -beams,"and

side members 43 provided with flanges 44 to fit over the draft beams. These side members 43 have longitudinal ribs 45 fitting into slidable grooves 46 provided therefor 1n the sides of a carriage 47. The carriage has supporting flanges 48 adapted to slide on the tops of flanges 44 of side members 43, and is yieldingly maintained against longitudinal movement by springs 49 bearing on each end of carriage 47 and oneach rigidly fixed end member 42. The top of carriage 47 is provided with a transverse or lateral roller seat 50 at right angles to the draft beams 8, in which are mounted rollers 51.

' l'ating strength or A plate 52 rests on these rollers to which is secured springs 53, which in turn are secured at their upper ends to the base plate 54 of the plunger or buffer member 55 rigidly attached to car floor frame and extending vertically downward through carriage 47, its lower end being adapted to support a truss and pendulum weight as explained under Fig. 4, where more than one such member is provided. This construction therefore affords a means of supporting the car body on the draftmember beams as well as at truck centers, it being possible by reguli-fting' power of .the springs 53 and by varying the number of such seats between trucks to transfer to and further utilize the necessarily strong draft member construction and through its sup-- portato'transmit to the journals such part of QthQsf-car body weight and load as may be jpractical without. lifting too great aprolportion "of the load from the .top centers of truckbots'ters. bufler element of this device is adapted to resist longitudinal movement or momentum of the car body and its load with relation to draft member and truck centers, by the resistance of springs 49 acting on the car body through carriage-47, plunger 55, and its base plate 54. The two sides of plate 52 toward the car ends bear lightly against plunger 55, and the other two sides permit slight clearance and are rounded on their inner edges, so that when the car body is laterally tilted from the vertical and springs 53 are compressed unequally, the plunger 55 will not bind against the sides of the plate 52. The roller construction permits tilted or hinged move ment ofthe car body with respect to draft member 8 without binding. and it will be noted that the lateral or swing play of the plunger bufi'er member 55 between the sides gear. In addition, a downward projection" of plunger 55 is not needed on freight cars to carry batteries or other appendages such indicated in Fig. 4. p In the construction shown in Figs. 9 and" 10, which is preferred for heavy car bodies and loads over that just described, the weight of draft member 8 is not supported by springs 14 on each side of collar 13 oncolumn 12, but is transmitted to bolster springs 20 by means of the following construction: Collar 13'is free to turn about column 12 but is restricted against vertical. slide thereon R by flanges 60. The column 12 is supported on column seat 11 but instead of said seat 4 to the bottom of pedestals 3, it is supbeing rigidly connected by lowerside pieces ported by links '61 from truck bolster '19.

Cross members 11" are secured to the lower side frame members 4 as in the case of column support member 11 (Fig. 8). These members 11*, however, constitute lateral guides or lower transom members which confine, thecolumn seat 11 and transmit the longitudinal thrust on same to lower side frame 4 in the same nianner that the upper transom members 23 "confine the bolster 19 (from'which the column'seat 11 is suspended) and-transmit the longitudinal thrust on same to upper-side frame 4'. The seat is guarded against excessive, lateral swaying by longitudinal guidemembers 62 secured on cross members 11 which are riIgidly connected to lower (side pieces 4. f 'desired,

the column seat ll ma? be made in one-piece or of rigid construction with bolster 19 instead of suspended therefrom by links 61, as indicated for freighttrucks in Fig. 13.

- Figs. 9 and 10 also show a modification of 8 and 9 shows that this construction permits bolster springs 20 to clear the center construction so that they need not be spaced apart as shown in Fig. 6, but can be spaced equally, as shown in Fig. 10. This construction also maintains a substantially fixed distance between the draft member and the car floor, which is desirable when a material part of the load is to be transmitted to draft member through the body bearings on same.

Fig. 4. illustrates an additional function of thecombination car support and longitudinal buffer device, as above described, applied in particular to passenger or other car bodies of the suspended spring supported type, although it may apply to cars of other types as well. The figure shows a method of supporting battery boxes or other car floor appendages on a specially constructed and easily removable truss which may be hung with its load from the ends of theextended plunger or buffer members 55. This weight with its rigid leverage on car floor frame will serve to steady the car body against sudden or jerky lateral rock or displacement. While the trucks with their flexibility of play conform to track grades, banking and irregularities without transmitting these movements to the car body as violently as in the case of cars of present construction.

Fig. 5 discloses two methods by which the car body may be lifted from the running gear. The first method consists of providing hooks or similar devices 66 at the upper ends of tension side members, which are attached at their lower ends to the underframe of the car body and to which lifting apparatus may be attached. The second method consists in supplying hooks or similar means 67 at the bottom of the car body, to which lifting apparatus may be attached. Chains or ropes 68 attached to hooks67 may be kept from harmful contact with the car body by a spreader 69 which also protects car body against inward or crushing pull upon lifting whennot uniformly loaded. In the modified construction shown in Figs. 11, 12, and 13, I have employed trucks with side frames 70 of a construction combolster 71, instead of being supported in the manner shown in Figs. 8 and 9, is provided with extended ends 71 resting on spring 72 mounted in frames 70, as in ordinary freight car trucks. Upper transom members and lower transom members 70 are provided, their functions beingsimilar to the function of corresponding transom members described with reference to Figs. 9 and 10. The frame is provided with guide bearing surfaces 73 adapted to maintain bolster 71 in position against twist by sliding contact with extension 74: on the bolster. In the construction shown in Figs. 11' and 12, the column 75 is supported on a platform 76, which in turn is supported from bolster 71 by links 77. Instead of this link construction, 'a preferred form may be used as shown in Fig. 13, where the platform 76 is rigidly secured or made integral with the bolster 71, thereby forming a strong, serviceable, one piece bolster construction. Fig. 13 also shows a modified form of column consisting of a lower part 78 made integral with platform 76, and a shaft 79 secured to the bolster and passing through the draft member-supporting-collar 80 and into lower part 78. Upper and lower transom members 70 and 70*, respectively, perform similar functions to upper and lower transom members previously described.

It is obvious that the parts above mentioned may be secured together or made in one piece as may seem best in practice without departing from the principles of construction set forth, and it is further assumed to be obvious that this construction may be applied to any truck now in general use.

It will be evident from the foregoing that my improved construction conduces to safety by loweringthe center of gravity of the car, by increasing the relative strength of its parts, by increasing braking efficiency, by producing a non-telescoping structure, and by producing a uniform control of the spiral movement of the car body at less torsional strain. The cost ofmaintenance and of equipment is decreased and a greater avail-v ability or utility of equipment made possible. Thus, in passenger service, light summer bodies may be substituted for heavy winter bodies, and vice versa, and in freight service, rail and water shipments maybe made in car lots by transferring the entire body without unloading from one means of transportation to the other. In freight terminals restricted to ground area, the car bodies may be removed from the trucks and stored loaded or unloaded at various levels, such facilities thus being limited only by the number of floors in the terminal build1ng. The application of my invention to a six-wheel truck is assumed to be obvious, as well as the application of strengthening means where needed, as for instance, the strengthening of the lower side frames against twist at their point of connection with the wheel pedestal, as applied particularly to the passenger car construction.
