Patented Aug. 19, 1947 FLOOR RACK HINGE Victor E. West, Chicago, Ill., assigner to Standard Railway Equipment Manufacturing Company, Chicago, Ill., a corporation of Delaware Application August 31, 1945, Serial No. 613,816

(Cl. IIE-422') i Claims. l

This invention relates to railway refrigerator cars and more particularly to the iioor construction for refrigerator cars of the overhead bunker type, but the invention is utilizable in railway refrigerator cars of other types.

The conventional refrigerator car floor is of wood with insulation thereunder and may be lined with a metal floor sheet to aid in keep-ing the wood and insulation dry. A gutter is formed at substantially the juncture of the floor with each side wall and a drain is provided therefor to carry the liquid outside o-f the car. One side of the gutter is joined to the flue sheet in a manner to provide a watertight joint. The floor racks for such cars comprises a plurality of preferably transversely extending spaced stringers to which are attached spaced longitudinally disposed slats extending from end to end of the car. Said racks are hinged to the car so that they may he raised against the side walls to thereby permit cleaning of the floor as by flushing with a hose, or otherwise, as preferred.

The principal object of the invention is to associate and arrange the elements of said hinge so that they cannot become disconnected when the floor rack is in upright position, and which may be readily disassembled when necessary.

Another object of the present invention is to provide a hinge structure for said racks which will not be in the path of any water in the gutter or on the floor, thereby reducing corrosion of said elements to the minimum.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing forming part of this application, and wherein like reference characters indicate like parts.

Figure 1 is a partial vertical section through the juncture of a refrigerator car oor and wall embodying the invention.

Figure 2 is a top plan view of the hinge structure showing its relation to the floor rack, gutter and side posts.

In the drawings the usual parts of a railway LA:

/lIl

adapted for use with overhead bunkers, the side wall iiues 'I conducting chilled air from a refrigerant compartment adjacent the car roof to the space 4 between the floor and floor rack 2.

The oor of the car comprises a metallic sheet I2; sub-floor I3; insulation material I4 and lower metallic sheet I5. A gutter I1 is formed in the floor of plate material, located at the juncture of the floor and wall and is provided with an outer wall I8 which extends upwardly adjacent the posts 8 and the upper end of which wall I8 underlaps the bottom edge I9 of the flue sheet 1, which edge I9 is turned down over wall I8 in plane therewith and secured thereto as by welding or otherwise. The gutter is provided with an upwardly extending inner wall 2| provided with a laterally extending flange 22 underlapping the floor sheet I2 and secured thereto. The gutter is preferably inclined and provided with a drain 23 for carrying the water which collects in said gutter outside of the car.

The oor rack comprises a plurality of spaced transversely disposed stringers 3 of wood, such as 2 x 4. Longitudinally extending spaced slats 2 are secured to the upper edge of the stringers to form the lading supporting rack. It will be understood that the entire floor rack for the car is made up of a plurality of sections and each section is hinged to the side wall and extends to the approximate longitudinal center of the car so that each section may be raised against the wall and the floor then cleaned as by flushing with a hose or otherwise.

It is desirable that the hinge structure for said rack sections be designed and applied to the car and rack so that when the rack is in normal lading supporting position there will be no load upon the hinge. The inner sill of the car is shown at 30 having a horizontal arm 3| upon which the posts 8 rest and are Secured thereto, as by the rivets 32. To the inner flange 33 of one of said posts 8 is secured the butt 34 of the hinge structure. In plan view (Figure 2) this butt is of channel shape comprising spaced

flanges

35 and 36 which extend inwardly and downwardly spanning the gutter, II, and each preferably terminates in an arcuate edge 3l. Extending between and slightly beyond said arcuate edges 31 is an arm 38, in cross section of the same curvature as said edges 3l, formed integral therewith or welded thereto as preferred, which arm 38 is in turn welded to the arcuate juncture of wall 2l of the gutter with the ange 22 thereof. The web of said channel shaped hinge butt is secured, as by bolts 39, to the post 8 at a point above the outer wall I8 of the gutter. Spaced inwardly from the post 8 a suitable distance and extending between the upper edges of said

flanges

35 and 36, is the hinge pintle 40. Just inside of said pintle 40 the

anges

35 and 36 are formed with aligned vertical shoulders 4I. The outer end of the stringer 3 terminates adjacent said shoulder 4l and the lower edge of said Stringer is charnfered, as at 42, parallel with the inclination of the

flanges

35 and 36 so as not to interfere with said arms when the rack is down, as shown in Figure 1.

The hinge strap comprises a member having a flat strip-like portion 45 bolted, as by bolts 46, to the chamfered end of stringer 3. Strap member 45 is also provided with a shoulder 47 corresponding to and positioned adjacent shoulder 4I when rack is down. A laterally extending hollow semicylindrically formed boss 48 extends between flanges 35-36 and partially encircles pintle 411 upon the upper side thereof. A cooperative member 50 is provided at its upper end with a hollow semi-cylindrical portion 5l which encircles the remainder of said pintle d and completes a bearing thereabouts. Member 5U is held to shouldered portion 4l' of strip 45 by means of bolts 52. It will be noted in Figure 1 that the bearing is of larger diameter than that of the pin 4E) and is concentric therewith, so that when the floor rack is down there is no weight at all on the hinge strap. When, however, the rack is raised the bearing 48-51 will rest and pvot upon the pin until the rack is again lowered.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:

1. A floor rack hinge structure for a railway refrigerator car having a wall, vertical ues associated with said wall, a vertical post between said lues, a floor having a gutter adjacent said wall and arranged to receive liquid from said flues, and a iloor rack, said structure comprising a butt and a strap, said butt spanning said gutter and having a portion secured to said post above the gutter, and a portion supported by said floor above the bottom of said gutter, said strap secured to said oor rack and hingedly attached to said butt.

2. A oor rack hinge structure for a rail-way refrigerator car having a wall, a floor having a gutter adjacent said wall, and a oor rack, said structure comprising a butt and a strap, said butt spanning said gutter and having a portion secured to said wall above the gutter, and a portion supported by said floor above the bottom of said gutter, said strapsecured to said oor rack and hingedly attached to said butt.
