8 Claims. (01. -366) This invention relates to movable seating abutments for container vehicles, and more particularly to seat forming abutments or seating abutments adapted for engagement with the base portions of containers and mounted for movement along the platform of the carrying vehicle in such manner as to afford adjustable stops for holding the containers against shifting. 1

One object of the invention is to provide in a container vehicle, va series of abutments which define seats for one or more containers and which may be individually moved toward or away Irom the sides of the car to accommodate containers of varying width. v

. Another object ofthe-invention is to provide trackways for guiding. the movement of such abutments, the trackways extending along the top surface of the vehicle platform and over the side edges thereof, whereby the abutments may be moved to positions in which they offerno ob-' struction to the lateralv shifting of containers onto or off the vehicle.

Other objects andadvantages characterizin our invention will become more fully apparent from the description hereinafter set forth of one embodiment or example of theinvention, having reference to the accompanying drawings, where: of:

Fig; VI represents a eros's'section, taken as in-v dicated by the lines VIVI oi'Fig; III;

Fig. VII represents" a perspective view of one ofthe container seating abutments.

With reference to Fig. I of "the drawings, the numeral ldesignates comprehensively a portion of a. railroad flat car, and 2 the floor or platform thereof. At spaced intervals-along the length of the car and at each side thereof, trackways are provided, constructed in the'manner hereinafter described, and associated" with each trackway thereis a container seating abutment 3. The container seating abutments are movable individually in a direction transverse to the longitudinal axis of the car a limited distance'fromthe side sills 4 and collectively serve to define seats for containers 0! varying base dimensions.

Each trackway' used for guiding the movement of acontainer seating abutment 3,-i'n the illus trated example of our invention, is formed or a pairof Z-bars-5 inlaid in the carfloor. The 2- bars 5 are disposed in opposite spaced; relation with their lower flanges 6 riveted to the underframe of the car, and with their upper flanges 7 disposed in the plane of the top surface of the car platform and projecting towards each other. At then-inner endsthe Z-bars 5- are supported on a longitudinal beam 8' comprising a part ofthe car under-frame, and at their-outer ends-the '2- bars 5 are supported upon the side sills 4. Attached to the web or each; side'sill 4', thereare ver tically extending z-bar sections 9 which form continuations of the Z-bars 5, extending at right angles thereto downward along. the side sills of the car; The Z-bar sections 9 have their outer flanges 10 riveted to the side sills 4 and have their inner flanges 1r projecting towards-each other at a spaced distance apart. 1 The inner flanges 11 of the 'z-bar' sections 9 at their upper ends join. the flanges '7 of the z barst, and at theiriower ends are turnedinward in. a horizontal plane as indicatedet 1 2, to form a pocket which serves to prevent removel of the container seating abutments 3. from the car. 'At the inner endsrof the z-bars 5, adjacent to the longitudinal beams 8, the z-bars or each trackway: are cross-connected by a yoke As most clearly shown in Figd'vll, the container seating abutments 3 are in the form of castings or substantially 'T-shaped crosses'ection, having a central transversely extending portion 16 and having 'alongitudinally extending wall 1'7 which defines therewith two'right angular pockets for accommodating cornersof two adjacent containers, such as represented at A in the drawings. The central transversely extending portion 16 has inclined surfaces 18- at the top thereof, and the longitudinally extending wall-1'7 has an inclined 45 the wall 21 of the central portion '16, each 'c'o'n tainer seating abutment 3 is formed with key--- hole slots 22 which are relatively wide near the top and relatively narrow near the bottom.

Moreover, at the base of each container seating abutment 3, there is formed. a-nut retaining pocket 23. Associated with each trackway, there is provided a screw 24 which hasanenlarged head 25 at itsrinnerend in ,engagementwith the yoke 15 which connects {each pair of Z-bars 5.. The screw 24 passes through fulcrumedon the yoke 15,. and-in its normal position extends centrally between the Z-bars 5,just beneath the top surface of the car platform 2, see Fig. IV. Each screw 24 has thereon an elongated rectangular nut 26 engaging its threadedportion; .Each screw 24 at its outer end isof-square or nuts shaped cross-section, as'indicatedat 27, so that it may be engaged by a socketed hand crank. Normally the nut .26 associated with the screw 24 fits snugly. within the pocket 23 ,of thecontainer seating abutment 3 and is. so. confined that incident .to the turning of j the screw,-the-abut ment will. be progressed inwardly or outwardly along the trackway. Howeventhe nut 26 may, when desired, betwithdrawn from its pocket 23 with upwardswinging of the screw 24, fulcruming on the yoke 15. -By swinging the outer end of the screw 24 in an upward direction, with removal of'the nut 26 from its pocket 23,. and .by turning the nut 26 through an angle of .90", so that its long axis. extends ina vertical direction, afcontainer seating abutment 3 may be released from its screw 24, with the nut 26 passing through the keyholeslots 22 at their relatively'wide portions.- With a container, seating abutment} has thus been released from its actuating screw 24, andpassedover the. endythereof, itmay, in an obvious manner, be passed downward over the side sill 4 of .the car to the position indicated in dot-and-dash lines in Fig. V.

The operation of the. container seating abutments 3 will be. apparent from the above :description. It will be. particularly noted, however, that by application of a socketed hand crank to the actuating screw- 24, the abutments 3. may be moved inwardly or outwardly so that they assume the desired positions for accommodating the base portions of the containers to be carriedon the car, such: positions depending upon the width of the-containers. Inasmuch as the screws. 24 have threads of relative short pitch, each abutment 3 in effect locked to the car except when its screww24 is beingrotated. More over, not .onlyare the abutments 3 maintained rigidly .in the desired position transversely of the car,.but by virtue of the engagement of their wings- 20 with the .Z-bars they are effectively restrained against tipping to one side or the other in adirection longitudinal of .the car.

Wherecontainers are handled at large transfer stationsby means of overhead cranes, it is not ordinarily necessary to change the positions of the container seating abutments 3, provided of course that all the containers being handled are of standard base dimensions. However, it frequently happens that containers have to be shifted onto or off railroad cars at Wayside stations where large crane facilities are not available. With. certain typesof container transfer apparatus used at. such wayside stations, including particularly apparatus in which hand-operated hoists are employed, it is desirable that are container seating abutments 3 be moved out of the way to facilitate the shifting of containers onto or off a car; and where the shifting is accomplished bysuch transfer apparatus, the seating abutments 3 are moved outwardly over the side edges of the car and downward along the side sills 4 to positions beneath the car platform 2. This enables the hoist operator to shift containers without having to raise and lower the, containers more than a very short distance. For example, ifit be desired to shift containers A from a railway car to an adjacent platform, the operator will first proceed to move all of the seating abutments 3 clear of the car platform 2. Then each container may be raised only an inch or so by the hand-operated hoist preparatory to shifting it from the'car to the adjoining platform. Furthermore, it will be readily seen that where nohoist facilities are available, by removal of the container seating abutments 3 to positions clear of the car platform 2 as shown in dot-and-dash lines in Fig. V, it is possibleto manually shove a container onto or off' the car without interference on the part of the container seating abutments.

While we have describedone example of the practice of our invention, andhave referred to one particular form of car construction which is desirably employed, it will be apparent that many changes may be madein the form of the trackways and container abutments herein described'without'departing from the spirit of our invention as defined in the annexed claims. I Having thus described our invention, we claim:
