to the right of the center of the 1igure, the portion to the left of the center line of the figure being shown in sectional elevation, taken on line 1 of Fig. 2 looking in the direction of the arrow; Fig. Q a central sectional elevation of a port-ion of the car, taken on line 2 of Fig. `1 looking in the direction of the arrow; Fig. a skeleton plan view, of the portion of the bottom framework shown in Fig. 2; and Fig. 4 a detail perspective view, showing the construction of the `side stakes and the manner of mounting them upon the transverse beams.

In constructing a car in accordance with my improvements, I provide a car frame formed of side trames a and end frames b, the end frames being provided with stakes o mounted on the outside thereof and secured to the top plates of the end sills hereinafter described. These side stakes are mounted upon the inner sides of the side frames over the transverse members of the bottom framework hereinafter described, .and are formed of tapered web portions d. The outer upright sides or edges of the stakes are. provided with vertical Hanges e and the inner edges with inclined iianges f, which extend from top to bottom of the stakes at right angles to the main web portions. The upper ends et the stakes are connected by channels (31 having their fianges directed outwardly and the lower ends of the stakes are simiiarl y connected by channels 18. The channels (31 and 18 are connected by diagonal members (50, which are secured to their inner faces. Planks (352 are vsecured to the outer faces of the stakes between said channels 61 and 1S. The diagonal members 60 are constructed of fiat plates, which lie against the inner faces of the planks and are secured thereto as well as to the channels. .The structure described forms a side truss capable of carrying theweight from thecenter and end parts of the car to thebolsters and the type of Ytruss is such that the diagonal members G0 are subjected to tensile strainsonly, thereby rendering it possible to construct ;th'eni of fiat iintianged metal plates. The construction of the diagonal members of such tlat plates avoids restricting the interior width of the car as would be done bythe use ot' tianged members, and Suchmembers will be necessary it' the truss were of a form iniposing compressive strains upon the diagonal. members. queen-post type and the diagonal members The truss is of the inverted slope downwardly away from the adjacent points of support, `tlralsis', the bolsters. By this means I am en 'bled te carry the weight of the car upon ti. c si'de trusses without the use of bulky trussesiwnioh would restrict. the interior dimensions of the car. structed according to my invention and provided with side trusses in the form above de scribed, the center sill serves merely to take the buiiing and draft strains and is supported from the bolsters, the load being transmitted to the bolsters by the side trusses and not by the center sill. A bottom trame is provided, having longitudinal center sills,

formed preferably of channel irons, and

each consisting of a cent-ral section y and end sections JL. The end sections of the eenter sills have vertical web portions 'i' of greater thickness than the web portions j ot' the central sections.

Bod y bolstcrs are mounted over car trucks of any ordinary and well known type and havingr supporting,r wheels rihe body bolsters are each formed of a pair otside plates Z which extend transversely from side to side of the car, beingl of greater depth at their central portions than at their ends, as snown in Fig. l. A top plate fm, which forms the tension member, extends from end to end` of the bolster and laterally beyond the outer faces of the side plates, being secured thereto by means of angles n, and a bottom plate 0 extends longitudinally of the bolster between the side plates near the lower edges thereof and is secured to the side plates by means of inner angle irons 2). A plurality of vertical-transverse plates g are mounted near the longitudinal center of each of the body holsters, and secured to the side members by means of vertical angle irons r. These plates provide the necessary resistance to the vertical thrusts or strains upon` the central hearings s. Upper lateral gusset plates r'. are secured to the opposite side plates by means of angle irons and bottom filler plates/v are mounted on opposite sides of the body bolsters over the laterally projecting' portions'of bottom gusset plates wwhich extend laterally beyond the side plates at the longitudinal central portion of the bolsterand are secured to the bottom flanges of the longitudinal center sills already described. Angle irons y have vertical lai'iged vportionsl, which extend inside of the side plates pt the bolster and are provided with horizontal. laterally extending flange portions extending between the bottom gusset plate andthe lower edges ot' the side plates, as shown in Fig. 2. The central sections of the longitudinalE center sills' are connected with the side plates of the body Vholsters by means of vertical connecting angles 3, and the end sections of such sills are secured tothe opposite sides ofthe body llhen roobeneath the dumping doors.

holsters by means of similar vertical angle members 4. Transverse beams are mounted upon the longitudinal sills at suitable intervals, formed of vertical web portions 5, which are secured to the longitudinal sills by means of angle irons forming bottom flanges for such transverse beams. Top angle irons 7 and 8 form upper lateral flange portions ot' the transverse beams, and the langle irons 8 are bent outwardly at their opposite ends, forming a. space between them and vthe vertical web portions of the transverse beams, into which extend the depending web portions 9 of the side stakes, which are mounted upon the ends of such transverse beams. The vertical web portions of the side stakes and transverse beams are secured together by means of suitable rivets,V`

as shown in Fig. 4. 4

Hinge plates 10 support the hinged sides of the doors. 4'These plates extend transversely over the center-sills from door to door and are provided with bottomangles l1, by means of which their lower edges are secured in position. The hinge plates'adjacent to the body holsters and end sills are secured to the top gusset plates which extend over the center sills, and those mounted near the transverse beams-or centrally of the car-areseeured 'directly to the top flanges of the center sills, as sho-'svn in Fig. These hinge platos are provided with top flanges 12, and tbe central lloor plank 13 is laid thereon. Hinkle members 14 are mounted upon opposite sides of the vert-ical web por tions of such plates at the opposite ends thereof, so as to form supports for the hinged members lvvhich are secured to the dumping bottom sections or doors 16,v such hinge members being connected by means of pivot pins 17.

The dumping doors extend longitudinally on opposite sides or" the ear between the transverse members of the carframe, and are adapted to swing upward to closed position so as to form bottom portions, as shown in Fig. l, and downward to inelinedopen dumpingr positions. The inner edges of the doors end beneath thefside edges of the center loor boards 13, and their out-er edges swing up into engagement with the bottom flanges of channel irons 18 which form the bottom-members ot` the side frames and are above the floor level. These channel irons are secured to the lewe/rends of the side stakes,` which, in turn, are secured to the body holsters by means of angle irons 19, as shown in Fig. 1. A

My improved mechanism for operating the dumping doors comprises rotatable dooroperating shafts 20,1Which extend on opposite sides of its longitudinal center Aof the car are journaled in the transverse members of.k

'lhese shafts the ear frame7 which include the body bolsters and transversebeams already described. Reeiprocatory shafts 21 eXtend parallel with these door-operatingshaftsbeneath the outer swinging portions of the dumping bottom sections or doors and are slidably supported by the transverse members of the car frame, bcing mounted upon inclined transverse tracks 2Q, the upper inclined surfaces of which extend upward and outward at an incline transversely of the car. The track members are secured to lthe body holsters and intermediate transverse bealnis-adjacent to the opposite ends of each of the dumping doors.

The door-operating shafts are each provided at suitable intervals with cranks 23, operatirely connected with reeiprocatory .shafts by means ot link members Q4. The door-operating crank shafts are mounted a snlicient distance inward from the outer swinging 'sides of the doors and inward from the reciprocatory sha its, so that the iinnement of the outer swinging` ends of the cranks to raised position will be as near as practicable in line. with the direction of movement of the reciin'matory shat'ts with which such cranks are connected. ln other wordsa the path of movement of the swing'- ing ends ot' the cranks Q3 when moving the doors to closed position upward and outward and, `a. near as possible. in line with the inclined surface portion ot the supporting track' member 92, and theretor as r )ar as possible bark of and inline with the path of movement ot' the reciprocatory shafts operated thereby. llnd sills are provided which are so constructed as to permit the gears ot the door-operating shafts. to be mounted beneath and outside, ot the inner face of the end sills in the desired position.

The principal member or main bod)Y portion of each of the end sills is formed of a channel beam Q5 having' top and bottom' flanges 2G and 27, both of which extend longitudinall)vv from end lo end of the sill without interruption or curvature. 'l`he flanges el the channel beam extend outward endwisf ot the ear and verl ical angular gusset il'flatesy QG are secured to and extend downward `lie-- low the lower edge ot' the channel beam so as to `liorln a suitable support tor the drawbar shank. Thess. vertical gusset plates are. a sufficient distance apart to forni a space beneath and at the center oi" the channel beam member adapted to permit the d rawbar shank to be mounted beneath the lower flange of the channel beam, and a drawbar supporting member Q8 of angle iron is secured to the lower portions et' the vertical gusset platesand extends across the space therelaetween. These gusset plates` have laterally or rearwardly extendingl vertical flanges Q9, which -are secured to the inner sides of the center sills by means of suitable rivets, and these rearward laterally extend4 ing tiange portions provided with upwardly projecting portions 30, which extend to the upper edge of the channel beam mernber formingl a support for the rear portion of a to i plate 3l. upon. the top of the channel beam member and extends over the laterally or rearwardly projectingr Hannes et the vertical gusset plates. Connecting angles 32 serre to eonneet the top plate with the upwardlyqprojectinga' portions 2.50, and connectingangles 32 are secured to the top plate and the' bot tom of the end stakes by means ot' suitable rivets.y so to torni an etlirient support t'or the end frames. l
