16 Claims.

This invention relates to improvements in floor racks for refrigerator cars, and more particularly to floor racks which are readily removable.

One object of the invention is to provide floor 5 racks for railway cars of the refrigerator type which may be completely removed from the car when desired to convert the same for use for lading which does not require elevation from the floor, and which may be quickly and easily 1.) replaced in position within the car to again restore the car to its original condition.

A more specific object of the invention is to provide a removable floor rack of the character described in the preceding paragraph comprising sections which are hinged so that they may be swung, out of the way, to a vertical position against the side walls of the car, wherein the rack sections are provided with hinge members, permanently attached thereto and securely but removably anchored to the walls of the car, whereby the rack sections may be quickly and easily detached and bodily removed from the car to convert the car for service which does not require elevation of the lading from the floor.

. Other objects of the invention will more clearly appear from the description and claims hereinafter following.

Figure 9 is an enlarged plan view of a portion of the bar shown in Figure 8. Figure 5 10 is a vertical sectional view, corresponding to the line Ill-10 of Figure 9. Figure 11 is a view similar to Figure 3, illustrating another embodiment of the invention. Figure 12 is a vertical sectional view, corresponding substantially to the 10 line l2l2 of Figure 11.

In said drawings, A indicates one end portion of a refrigerator car body provided with the usual insulated walls, floor, and roof, the side walls of the car being indicated by 202fl, the 15 end wall by 2|, and the floor by 22. One of the bulkheads or transverse partitions which separates the ice compartment at the end of the car from the remainder of the car is designated by 23. As well understood by those skilled in this art, two such bulkheads are provided in each car, one at each end thereof, and the space between said bulkheads serves to accommodate the lading. When the car is used for lading requiring elevation from the floor, the entire floor space between said bulkheads is covered by a floor rack structure. It is the common practice to employ a floor rack structure composed of a plurality of separate sections, comprising two duplicate sets, the sets being divided lengthwise of the car and each set being divided transversely of the car into sections.

My improved floor rack structure, as shown most clearly in Figure 1, comprises a plurality of similar sections 24-44, two of which are 35 shown in full in Figure l, and two adjacent sections of which are shown broken away. The sections 24 are arranged in sets at opposite sides of the center line of the car and cover the entire floor area of the car which is available for lading. As will be understood, each complete set may be composed of any desired number of individual sections.

Eachsection 24 of my improved floor rack structure comprises spaced transverse slats 2525 secured to laterally spaced, longitudinally extending, supporting beams or stringers 2626. Each section 24 thus forms a unit which is bodily removable from the car.

Referring first to the embodiment of the invention illustrated in Figures 1 to 8 inclusive, each floor rack section 24 is provided with a plurality of hinges 2T, 21, and 28. The hinges 21, 21, and 28 of the sections of the fioor rack serve to support said sections in such a manner that the same 55 plate sections 3! and 32.

may be swung upwardly to vertical position against the side walls of the car, and any wellknown means may be provided for holding the same in the vertical position. In order to positively hold the rack sections against endwise and sidewise displacement when in horizontal position on the car floor, certain of the hinges thereof are detachably anchored to the side wall of the car. As shown in the drawings, the hinges 21-21 are anchored to the side walls 20-20 of the car while the hinges 28-28 are not so anchored, but mere- 1y supported on the floor. Although, as herein disclosed, each section is provided with three hinges 21, 21, and 28, two of which, namely, the hinges 21-21 are anchored to the car wall, it will be evident that a greater or lesser number of hinges may be provided on each rack section 24, any desired number of which may be anchored to the car wall.

The hinges 21-21 are preferably located at opposite ends of the section 24 and the hinge 28 midway between the hinges 21-21.

The hinges 21 and 28 are of similar design except as hereinafter pointed out. Each hinge comprises a pair of cooperating pivotally connected hinge members 29 and 30 which are preferably in the form. of castings. The hinge member 29 includes a right angular base portion composed of connected platelike sections 3| and 32 disposed at right angles to each other, and a vertically disposed central web 33 formed integral with said The web 33 has the lower edge thereof inclined away from the platelike section 32, as clearly shown in Figures 3 and 6. The web 33 is provided with a transverse pivot pin-receiving opening 34 which is reenforced by bosses 35-35 at opposite sides of the web, as shown in dotted lines in Figures 2 and 5. The base portion of the hinge member 29 is fixed to the floor rack section 24, the platelike section 32 thereof being in flat bearing engagement with the outer side of the outermost stringer or beam 26 of the rack section 24, and the platelike section 3| bears on the underneath side of the projecting endof one of the slats 25 of the rack 24 and is secured thereto by screws or similar securing elements. As shown in Figure 1, the slat 25, to which the hinge member 29 of the hinge 21 is secured, is preferably the second slat from the edge of the rack section, while the slat 25, to which the hinge member 29 of the hinge 28 is secured, is located substantially centrally between the ends of the rack section.

The hinge member 30, which cooperates with the hinge member 29, includes a base portion comprising a horizontal platelike section 36 and a right angular vertical platelike section 31 formed integral with the section 36. The base portion is provided with a pair of spaced parallel transverse webs 38-38 having upstanding hinge eye portions 39-39 thereon provided with aligned hinge pinreceiving openings. The webs 38-38 are formed integral with the base portion of the hinge member 30 and the upstanding hinge eye portions embrace the perforated portion of the web 33 of the hinge member 29. The hinge members 29 and 30 are pivotally connected by a hinge pin 40, preferably in the form of a bolt, extending through the openings of the hinge eye portions 39-39 of the hinge member 30 and the opening 34 of the hinge member 29. The hinge plate section 31 of the hinge member 30 of each hinge 21 is provided with a horizontally disposed T-shaped head 4| which projects from the rear side of said plate. The T-shaped head 4| serves to detachably anchorthe hinge member 30 of the hinge 21 to the side wall 20 of the car, as clearly illustrated in Figures 2, 3, 4, and '7 As shown most clearly in Figures 2 and 3, the side wall 20 of the car is provided with a pocket 42 adapted to receive the enlarged portion of the T-head 4| of the hinge member 30 of the corresponding hinge 21. As will be understood, the walls 20-20 of the car are provided with a plurality of such pockets 42, one for each hinge 21. Each pocket 42 is partially closed by a slotted cover or anchoring plate 43 which serves as an anchorage for the T-head of the corresponding hinge 21. As shown most clearly in Figures 2, 3, 4, and 7, the slot 44 ofthe plate 43 has a relatively wide upper section and a relatively narrower lower section. The wide upper section of the slot 44 is of such a height and width as to permit easy insertion of the wide portion of the T-head 4|, while the narrower lower section of said slot is restricted in width to fit the neck portion of the T-head and have the projecting side portions of said head overhanging the plate at opposite sides of said narrower section of the slot to thereby lock the head against withdrawal in an outward direction. The heads 4|-4| of the hinge sections 30-30 thus securely anchor the hinges 21-21 to the side wall of the car when the parts are in the position shown in Figures 2, 3, 4, and 7, thereby holding the associated rack section securely anchored to the car.

As shown in Figures 5 and 6, the hinges 28-28 differ from the hinges 21-21 only in that the hinge members 30-30 of the former are not provided with anchoring heads 4 |-4 The hinges 21, 21, and 28 of each rack section 24 are preferably connected by a longitudinally extending angle bar or beam 45 comprising a horizontally disposed base portion 45 provided with an. upstanding integral flange 41. The horizontal base portion underlies the bottom platelike sections 30 and the upstanding flange 41 abuts the rear sides of the vertical platelike sections 31 of the hinge members 30 of the hinges 21, 21, and 20, and are secured thereto in any suitable manner, being preferably welded as indicated in Figures 2, 4, and 5. As shown in Figures 2 and 7, the flange 41 is suitably recessed to accommodate the neck portions of the T-heads 4|-4| of the hinge members 30-30 of the hinges 21-21. The bars 45 form bracing and stiifening members for the bases 36 of the hinges 21, 21, and 28 and hold these hinge members in alignment. The base portion 45 of each bar is provided, at spaced intervals, with depending prongs 48-48, as clearly shown in Figures 8, 9, and 10 to hold said bars against endwise slippage. The prongs 48-48 are preferably formed by slitting the metal and bending down the end portions of the slit sections.

The embodiment of the invention illustrated in Figures 11 and 12 involves a modified anchoring means for the hinge members 21-21. As shown in said figures, the hinge 21 has the head 4| of the hinge member 30 thereof provided with a neck portion 48 which has the opposite side faces thereof downwardly and inwardly converging, thereby providing a. wedge shaped section. The inner end faces of the laterally projecting portions of the T-head 4| are inclined to the vertical as indicated at -50. The cover or anchoring plate 43, which closes the pocket 42, has the narrower lower section of the slot 44 downwardly tapered to correspond with the taper of the wedge shaped neck section 49 of theT-head 4| so that the neck section will be wedged into the slot to positively hold the hinge 21 against lateral play when the latter is anchored to the plate 43 by the head 4|, as most clearly illustrated in Figure 12. The walls of the plate 43 at opposite sides of said narrower section of the slot 44 are thickened, the inner faces of said thickened portions being correspondingly inclined to the inner end faces of the head 41 of the hinge member 30, thereby providing wedge acting portions which wedge against the head when the latter is forced down to positively lock the hinge member 30 against movement toward and away from the side wall 29 of the car.

When it is desired to convert the car for serice for lading which does not require elevation from the floor, the rack sections are detached and completely removed from the car, thereby making available the maximum lading capacity of the car. In detaching the different rack sections, it is merely necessary to lift the outer side portion of each rack section until the heads 4l4l of the hinges 21-41 register with the upper or enlarged portions of the slots 44-44 of the anchoring plates 4343 and then withdraw the heads through said openings by pulling the rack section away from the side wall of the car. To replace the rack sections, the reverse procedure is followed, the heads 4l-4l of the hinges 2'i21 being entered through the enlarged portions of the slots 4444 of the anchoring plates 4343 and then moved downwardly to engage the same in back of the anchoring plates at the lower narrow slotted portion thereof. As will be evident, the hinges 2121 are thus securely anchored to the side wall of the car and held against lateral displacement by the neck portions of the heads thereof, which neck portions snugly fit in said lower narrower portions of the slots in the embodiment of the invention shown in Figures 2, 3, 4, and '7 and which neck portions have wedging engagement with said slots in the embodiment of the invention illustrated in Figures 11 and 12. When the rack sections have been anchored to the walls of the car, the hinged arrangement thereof allows the same to be swung upwardly out of the way against the side walls of the car in the usual manner.
