This invention relates to railway cars, and more particularly to railway carshaving movable floor structures, and has foran object-a new an improved railway car of this character; r

A further object of the invention is to provide a railway car having an elevatable floor or platform, which maybe disposed upon the main "floor of the car while being loaded, and which may be elevated to a plurality of different positions within the car, dependent upon the nature of the lading.

-A still further object of the invention is to provide hydraulically operated mechanism :for

elevating and lowering the false floor or platform, in which the hydraulic mechanism comprises telescopically extensible sections housed in cylinders which are suspended beneath. the main floor of the car, and which permit the platformv to rest upon the main floor or to be elevated to 3 f diiferent positions within the car.

Another object of the invention is to provide a plurality of hydraulically operated locking means which are adapted to support the platform in various elevated positions, and which are re- :leasable simultaneously to permit the platform to be lowered.

- Still another object of the invention is to pro- 3 '13 Claims. (01. 105 s70)" vide a railway car having longitudinally norrugated .side walls, in conjunction with a plurality of attached channel-shaped posts, which accom modate roller means carried by the platform, and wherein the rollers operate not only to reduce friction to a minimum during motion of the platform, but the roller means cooperate with the posts to prevent shifting or displacement of the platform and the lading carried thereby while the car is in transit.

It is also an object of the invention to provide a railway car which carries hydraulic mechanism operated through a motor driven pump, and

wherein the motor may be plugged into any convenient receptacle outlet of a type widely used in railroad yards, or which may be energized by batteries carried by the car in case of emergency.

Other and further objects of the invention will appear from the following specification and attached claims, and from the accompanying drawings in which: 7

As shown-in the drawings, the invention-comprises a railway car having a main or usual floor It, mounted in the usual way upon a center sill The car is also provided with side walls 13, having longitudinally extending corrugations l4, corrugated end W2111S'l5, and a roof I6. The side walls l3 and end walls 15 are provided with spaced vertically extending channel shaped posts I? and I8, having their flanges inwardly disposed to present the open channels inwardly toward the car interior, and the posts i1 and H3 are rigidly secured to the Walls I-3 and I 5, as by the usual riveting. I

Disposed within the car is a false floor or platform- I 9, which extends substantially the length and width of the interior of the car. The platiorm -l 9 comprises flooring boards 20 having'their ends supported upon longitudinally extending 3 roller 29, rotatively carried upon an axle so, which has its ends riveted in the flanges 21 and 28. The flanges 2'! and 28 of each bracket 25 project be tween the flanges of the channel members F and i8, and the roller 25 is adapted to roll upon the web of the related channel post. The flanges 27 and 28 of the brackets .215 are spaced apart a distance only slightly less than the distance between the flanges of the channel posts ii and it, so that edgewise movementv of the platform |9 isprevented and the edgewise stresses which occur in transit, or when the car comes to a stop, are

transmitted through the posts i"! and i8 and toi a locking means 41, such as already described, will be located a predetermined distance upwardly from the main floor II, as indicated at 52, and another locking means 41, will be located at a higher level, as indicated at 53. Adjacent pairs of locking means 41, are connected to operate together, and this is accomplished by connecting rods 54 and 55 which extend between pairs of locking mechanisms 41. The inner ends of the connecting rods extend into a cylinder 56, as best shown in Figure 8, and the rod ends are provided with piston heads 51 and 58, limited in their approach toward each other by suitwalls [3 and 45, which are braced against deformation by the corrugations of said walls The flanges 21 and 28 are included as parts f angle irons having laterally extending flanges 32' riveted, as by rivets 33, to the outer surface of. the E web of one of the channel members .2 0122. e,

For elevating and lowering the platform "i8; there are provided a plurality of telescopically extensible -retractible hydraulically operative 'mechanisms 34. Each of the mechanisms 34 comprises a main cylinder or housing 35, suspended belcw the main floor H or the car, and

preferably mounted upon, or atached to, a cross beam 35 of the car. Th cylinder or housing 35 has its open end 31, disposed below, or substantially flush with, the upper surface of the main floor H of the car. Telescopic extensible-retractible sections 38, are adapted to be entirely housed 'within the housing cylinder 35, when it is desired to have the platform It rest upon the floor H, and when hydraulic fluid is supplied to'the cylinder 35, the sections 33 may be extended'difierent distances to raise the platform is to diilerent levels, the outermost section of each mechanism 34 being adapted to be connected to the lowermost flange of the side or end channel members 2| and 22, as indicated at 38.

As best shown in Figure 9, the housing cylinders 35 are supplied with actuating fluid through pipes 4U, connected with a pump 4|, which takes its supply of fluid from a reservoir 42, and the pump 4| is adapted to be driven by a motor 43. The supply wires 44 of the motor may be connected with receptacles usually present at convenient positions in a railroad yard, or may be connected to a battery carried by the car itself,

a switch 45 being provided for controlling the motor.43'. A valve 46 is provided so that after the platform has been raised to the desired position by the hydraulic mechanism, the valve 46 may be closed to retain the platform at the desired elevation. When the valve 45' is opened the fluid in the pipe is returned to the reservoir by the weight of the platform,"assuming that it is free to descend.

Mechanism is provided for looking or supporting the platform '95 in a plurality of ele vated positions. This mechanism preferably takes the form of locking means, associated with selected channel'posts H, as indicated at 41.

Each locking means comprises a saddle or seat 48, formed on selected brackets 26, the saddle or seat 48 being elongated, and formed in the under surface of a cross piece 49, which has its ends connected to the lower portions of the flanges '21 and 28 of the selected brackets 25. Adapted to be accommodated in the elongated saddle or seat 48 is a sliding bolt 50, which may be projected into apertures 5|, formed in the flanges of the channel posts Preferably the locking means 41, are arranged in pairs, and at different vertical levels in the car. For example,

and 58, a supply pipe 5| enters the cylinder 56 between the end thereof and the piston head 51, and another pipe 62 enters the cylinder 56 between the opposite end and the piston head 58. As best shown in Figure 10, the cylinder 56 at one level is duplicated for operating the looking mechanism 41, at a different level, as indicated at 65, the cylinder 63 having the same mechanism associated therewith as the cylinder 56, and supplied from the pipes 6|, 62 and 63.

Preferably, as shown in Figure 10, there are four groups of cylinders, 56 and 53, of the character already described, and the described group being indicated at .64, and the remaining groups at 65, 66 and 61. These groups are supplied with operating fluid through supply pipes 68 and 69, controlled by a valve 15, interposed in a pipe 1|. The pipe 1| leads to a pump 12, driven by 'a motor 13, which may take its energy from a. receptacle in the railroad yard, or from a battery carried by the car, as explained in connection with the hydraulic mechanism 35.

' In operation, and assuming that the platform I9 is resting upon the main floor ll of the car, it will be apparent that if the car is to be loaded with the type of lading which may be packed to the roof of the car, the platform l9 may remain in its lowermost position. -In thisposition the platform l9 occupies very little space, and the hydraulic operating mechanism is removed entirely from the interior of the car. In other types of lading, where it is desirable to segregate the types, the platform may be elevated to the top level, so that the entire car interior is unobstructed. When it is desired to elevate the platform to the second level, and assuming the valve 46 to be open, the pump 4| is started, and fluid from the reservoir pumped into the cylinders 35. This causes extension of the telescopic sections 38 to raise the platform. When the platform has reached a position a little beyond the top level, the valve 46 is closed, and the motor 43 cut out.

The valve 10 is then positioned to permit passage of fluid through the supply pipes 58 and pipe 60, when the motor 13 is started, and this causes the fluid to enter the cylinders 55 (and the cylinder 63, as well), and press the piston heads 51 and 58 away from each other, causing the connecting rods 54 and 55 to position the sliding bolts in supporting'relation with respect to the seats or saddles 4B. The valve 45 is then opened, allowing the platform IE! to begin descent, after which the seats 48 come to rest upon the locking mechanisms 41. The same action takes place when the platform is elevated to the lower level.

When it is desired to lower the platform l9, the same is elevated slightly above the locking means 41, the valve 18 operated to supply fluid agein L through the pipe 69, resulting in retraction of the-locking bolts -50, and permitting the platform 71:79 to' descend of its-own weight, such descent retarded by return of the fluid to the 'reservoi-n-asthrougha restrictedopening. Movefnient of the locking bolts 50' toward retracted position, of course returns the eactuating'iiiiid from between the piston headed) and "58 to the source-of supply. During the vertical movements of the platt9, the antifricti'on rollers 29 travel'nver the websof the posts I -1 and -l-8', prevent'bi'nding of the platform IS in its vertical movement, and cut down the power necessary in maneuvering the platform. When the platform I9 is in one of the three positions described, that is on the floor of the car, or at the first level, or at the second level, edgewise movement of the platform, either longitudinally or transversely of the ear,

is prevented by reason of engagement of the roller brackets 26 with the flanges of the posts I! and I8, and consequently in transit, there can be no shifting or edgewise movement of the platform, and the stresses in an edgewise direction are transmitted through the posts I I and I8 to the reinforced car walls l3 and I5.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
