18 Claims.

This invention relates to improvements in means for removably mounting floor racks of refrigerator cars.

One object of the invention is to provide a removable floor rack construction for railway cars of the refrigerator type, hinged to the car in such a manner that the sections thereof may be swung upwardly out of the way to substantially vertical position, the hinge members of each rack section, which provide for the swinging movement,

being so designed and arranged that they become readily detachable from the car upon the rack being swung to a predetermined position.

A more specic object of the invention is to provide hinge members of the character set forth in the preceding p-aragraph, which are pivotally connected to the hinge socket elements mounted on the car, wherein the socket elements are provided with retaining means and the pivots of the hinge members are designed and arranged to slidelengthwise of said sockets during swinging movements of the rack sections to assume a position beyond the limits of the retaining means to render said hinge members `readily detachable from `the socket elements.

A further kobject of the invention is to provide a detachable hinge `member having a hinge pin swingingly` connected to a keeper element, provided with a guideway within which the pivot is both rotatably and slidably accommodated, wherein ,the .hinge member is provided with means for closing the guideway to seal the same against entrance of dirt and other foreign material when the hinge member is swung to a predetermined position; i

A still further object of theinvention is to provide a removable floor rack construction hinged to the floor. of the car by pivot means on the rack, detachably connected to a socket element mounted in the floor of the car, wherein the rack carries-means for effectively closing the socket to exclude dirt and other foreign material when the rack is either `in` `fiat position overlying the floor or in raised vertical position against the wall `of the rcar.

Other objects of `theinvention will more `clearlyappear fromthe ,descriptionand claims hereinafter following.

In thehdrawings forming a part of this speci- 50 catiorn. Figure 1 is a vertical sectional view through a portion of a floor rack section, corresponding to the line l-I of Figure 3, also showing the inner face of a portion of the side wall of a `refrigerator car, and illustrating my improve- 53 ments in connection therewith. Figur@ 2 is. a top (Cl. 1li- 174) plan View of the floor rack section shown in Figure 1, partly broken away, showing the side wall of the car in horizontal section, illustrating the improvements shown in Figure 1. Figure 3 is a vertical sectional View, corresponding substan- 5 tially to the line 3--3 of Figure 1. Figure 4 is a View, similar to Figure 3, but showing the rack section swung upwardly to vertical position against the side wall of the car. Figure 5 is a vertical sectional View in a plane parallel to the 10 side wall of the car and extending through a portion of a floor rack section and the floor of the car, illustrating another embodiment of the invention, said section being taken substantially on the line 5-5 of Figure 6. Figure 6 is a vertical 15 sectional view, corresponding substantially to the line 6-6 of Figure 5. Figure 'I is a horizontal sectional view, corresponding substantially to the line 'l--l of Figure 6. Figure 8 is a View similar to Figure 6, but showing the parts in a different 20 position, the rack being illustrated as swung partly upwardly. Figure 9 is a view similar to Figure 6, but showing the rack section swung upwardly to vertical position against the side wall of the car. v 25 In said drawings, l0 indicates a portion of one of the side walls of a refrigerator car, and Il the adjacent portion of the floor thereof. One of the sections of the floor rack is indicated by l2, a portion only of said section being shown. The 30 oor rack section I2 is of a type commonly employed in refrigerator cars. As is well known to those skilled in this art, the floor rack of a refrigerator car is composed of a plurality of similar sections like the section I2, these sections be- 35 ing arranged in sets at opposite sides of the center line of the car and covering the entire floor area which is available for lading. The sections at opposite sides of the center line ofthe car are usually arranged to be swung to vertical position 40 against the corresponding side wall so as to clear the iloor and make the same accessible. When the car is used for lading requiring elevation above the floor, the floor rack sections are disposed in horizontal llat position overlying the iloor and, as hereinbefore stated, cover the entire floor space available for lading. It is a common practice to remove the floor rack structure from the car to render the car available for lading which does not require elevation above the floor of the same, and for this purpose the individual sections are made removable as shown in Olander Patent No. 2,106,852, February 1, 1938. The structure of the rack section l2 in connection with which my improvements are disclosed is substantially the same as that of any one of the individual sections disclosed in the Olander patent. The section I2 comprises transverse, spaced slats secured to laterally spaced, supporting beams or stringers extending lengthwise of the car. These slats are indicated by I3--I3. One only of the stringers of the rack section is shown in the drawings and the same is indicated by III. Each section I2 forms a unit which is bodily removable from the car.

Referring first to the embodiment of the invention illustrated in Figures 1 to 4 inclusive, the fioor rack section I2 is connected to the floor II of the car by my improved hinged means, indicated by A. A number of such hinge means pivotally support the rack section I2 at a plurality of points along the outer edge of the rack section and adjacent the corresponding side wall of the car.

My improved hinge means A comprises broadly a hinge member B fixed to the rack; a hinge socket or keeper member C fixed to and seated in the floor of the car; and a pivot member D formed rigid with the member B and engaged with the member C.

The hinge member B comprises a pair of substantially flat webs I5 and I6 at right angles to each other, and a pair of arms I1 and I8 respectively parallel to the webs I5 and I6 and at right angles to each other. rlhe webs I5 and I6 preferably correspond in width to the width of one of the slats I3 of the rack section I2. The hinge member B is fitted to the section I2, with the web I5 underlying the projecting portion of one of the slats I3 and the web I6 abutting the vertical outer face of the outermost stringer I4 of said rack section, and is secured by bolts I I6- IIS-IIE, extending through said webs I5 and I6 and the slat I3 and Stringer I4, respectively. The arms I1 and I8 are of lesser width than the webs I5 and I6, and the arm I1 is reenforced by a longitudinally extending central rib I9 on the outer side thereof. At the corner junction of the arms I1 and I8, the hinge member B is provided with an enlarged projecting portion inclined with respect to both of said arms. This projecting portion carries the hinge pin D, which is formed integral therewith, and projects from opposite sides of said portion in the manner of trunnion means and forms therewith a T-head. As will be seen upon reference to the drawings, the hinge pin D is parallel to the Stringer I4 and outwardly offset with respect to both arms.

The arm I1 is laterally enlarged at its outer end, said enlarged portion projecting from opposite sides of the arm, thus forming a T-headed end portion 26. The narrower remaining portion of the arm I1 and the entire arm I8 are made of the same width for a purpose hereinafter pointed out. As shown most clearly in Figures 3 and 4, the arm I1 extends beyond the web I6, and said extending portion underlies the stringer I4, abuts the bottom face thereof and projects beyond said stringer, the T-headed section thereof being located beyond said Stringer. The arm I8 projects a short distance beyond the web I5, engages the outer end edge of the slat I3, as shown in Figure 3, and terminates below the top of said slat.

The hinge socket or keeper member C, which is preferably in the form of a casting, is seated or completely sunk into a pocket I2I provided in the oor II of the car. The socket member C includes a substantially rectangular, horizontally disposed, at plate 2I, which is countersunk into the floor II so that the top surface of said plate is flush with the top surface of the floor. The plate 2I forms the top wall of the socket member C. The socket member C has spaced side walls 22-22, end walls 23 and 24, and a bottom wall 25 spaced from said top wall. rIhe end wall 23 is preferably rounded, as shown in Figure 4, and the end wall 24 is inclined upwardly and forms a continuation of the bottom wall 25. As further shown in Figures 3 and 4, the pocket I2I is continued for a short distance beneath the side wall III of the car and the pocket portion of the casting C, which snugly fits the pocket I2I, partially underlies said side wall. The platelike top wall, which is countersunk into the iioor, protrudes beyond the side walls 22-22 of thev casting C and thereby provides securing anges by which the casting is fixed to the floor. Screws extending through the plate 2| and into the floor are preferably employed for rigidly xing the socket casting to the floor. The plate 2I is longitudinally slotted, as indicated at 26, said slot being transversely enlarged at the end thereof remote'fr'om the wall III of the car, as indicated at 21. The enlarged portion 21 of the slot is of such a shape and width as to freely admit the pivot pin member D of the hinge member B, vand the width of the slot 26 is such that the arms I1 and I8 fit the same to close said slot against admission of foreign material. As will be evident, the slot 26 is of generally T-shaped formation and the narrower portion thereof provides, in effect, side ledges or retaining walls which overhang the guideway 28 at a point between the side walls 22-22 of the socket member'C, which ledges or retaining walls prevent disengagement of the pivot pin D from said guideway when said pin is located between said ledges. As will be evident the enlarged portion 21 of the T-shaped slot is provided by cutting away the retaining walls. The end of the slot 26 remote from the enlarged portion 21 thereof terminates ush with the inner surface of the side wall I0 of the car, as clearly shown in Figures 3 and 4. As shown in Figures 3 and 4, the hinge pin D of the member B is engaged in the guideway 28 and pivotally supports the floor rack section I2 in such a manner that it is reliably anchored to the car while being swung from horizontal to vertical position, and vice versa. When in the position shown in Figure 3, with the rack I2 horizontally overlying the oor. the arm I1 of the member B is seated in the slot 26 of the socket casting C, effectively closing the same, the enlargedT- headed portion 22 of said arm snugly fitting the enlarged T-portion 2'! of said slot to seal the same. When the rack is swung to vertical position against the side wall of the car, as shown in Figure 4, the arm I8 and the pivot pin D close the slot 26 and its T-shaped portion 21. The socket member C is thus protected from accidental entrance of dirt and other foreign matter, which might otherwise interfere with the proper operation of the hinge means. In this connection it is pointed out that the hinge member B when in the position shown in Figure 3 is effectively held against lengthwise movement with respect to the socket member C by shouldered engagement of the T-headed end of the arm I1 with the end wall of the enlarged portion of the slot 26.

When the section I2 has been anchored to the car, the hinged arrangement thereof allows the same to be swungV upwardly Vout Vof the way against the side wall `of .thelcar in the :usual manner, andi, as is lcommon practice, to be supported in said out of the way position by suitable holding or latching means. As `the rack sectionis swung from the horizontal position shown in `Figure toward the vertical position shown -in Figure 4, it `swings on thehinge pin Dwhile the arm i8 ofthe hinge member B rides downwardly lonthe side 'wallet `'the roar, thereby forcing the hinge pin to travel `from lone 'end to the other of the guideway, 'while rotating, until it nnally reaches the position shown in Figure 4 and comes into alignment with `the enlarged portion 21 of the slot 23. The arrn IB thus forms in V'effect 'a lever member which rides on thewside wall ofthe car to control said sliding movement of the pivot. As will be evident when Athe parts reach the last named position, the rack section may be readily detached from the car by merely raising the same so as to disengage the hinge pin D from the socket member AC, the pin passing freely upwardly through the enlarged opening 2"'1 of the slot 26.

When it is desired to` convert the `car for service for lading which does not require elevation from the floor, the various rack sections l2 are detached in the manner described and completely removed from the car, thereby making available the maximum lading capacity of said car. It is further obvious that when the rack sections are in horizontal position, overlying the `floor, they must be rst swung to vertical position before detachment and removal of the same can be effected.

To replace the rack sections in the car, each section is placed in vertical position against the corresponding side wall of the car and the hinge pin engaged within the socket C by passing the pin through the enlarged opening 21 of the slot 26 into the guideway 28 as illustrated in Figure 4. The rack sections are thus made ready 'for use and are securely anchored to the car for swinging movement and into overlying relation with the floor.

Referring next to the embodiment of the invention illustrated in Figures 5 to 9 inclusive, the floor rack section I2 is connected tothe side wall Ill of the car by the improved hinge means E, several of which are employed in connection with each rack section in the same manner as the hinge means A, hereinbefore described.

My improved hinge means E comprises broadly a hinge member F fixed to the rack; a hinge socket or keeper member G xed to the side wall of the car; and a pivot element H formed rigid with the member F and engaged withv the socket member G.

The hinge member F comprises a bracket portion 30, xed to the floor rack `section |2, and an outwardly extending, right angular arm 3| on said bracket portion having the relatively heavy angular end section thereofA upstanding with respect to the rack section and provided with laterally projecting trunnions above the level of the rack which form the pivot pin `element H or pivot of the hinge means E. As clearly shown, the pivot pin portion of the angular section of the arm 3| is in the `form of a T-head. The bracket portion 30 of the hinge member F has a substantially flat platelike web portion 32 by which the bracket is secured to the outer face of the Stringer I4 which is nearest the outer edge of the rack section, the web bearing on the stringer and being fixed thereto by bolts 33-33 or other securing elements extending through said web and 4the stringer. c

' is shown in Figure 8.

`The inner section 'of the arm 3| includes a nat platelike portion or web 34 having an upstanding central rib 35, said platelike portion being disposed at right angles to the web 32 and continuous therewith. The arm 3| is preferably reeniorced by laterally projecting ribs 36-36 along its edges. `As shown most clearly in Figure 5, the rib 35 of the platelike portion 34 is seated between two adjacent slats |`3|3 of the rack I2, and the platelike portion 34 at opposite sides of said rib 35 underlies these slats and is secured thereto by bolts `or other fastening elements, also indicated by 33, extending through said platelike portion and the slats |3|3.

The hinge socket or keeper member G, which is preferably in the `form of a casting, is seated in or completely sunk into a pocket 31 of substantiall'y circular outline provided in the face of the vertical side wall I0 of the car. The socket member G includes a lsubstantially circular, vertically disposed, at plate 38 and a boxlike chamber 38 of substantially rectangular outline, formed on the rear side of said plate, the boxlike portion 'being of smaller size than the plate so that the latter projects laterally beyond the former on all sides thereof. At opposite sides of the boxlike portion, the plate 38 has inset portions 40h40, the back walls of which are in the same plane as the back wall of the boxlike portion 39. The socket member is secured in place by any suitable securing elements, preferably bolts, which extend through the back walls of the inset portions 411-40, the nuts of the bolts being accommodated in the recesses formed by said insets. The plate 38 forms the front wall of the boxlik-e portion 39 and is provided with a vertical slot 4i disposed centrally between the vertical side walls of the portion 39 and of the same length as the vertical interior dimension of said boxlike portion. The slot 4| is laterally enlarged or widened near its lower end, by cutting away the metal of the plate 38 at opposite sides of the slot 4| as indicated at 42-42, thereby providing an opening of substantially cross shape. The widened portion 42--42 .corresponds in width to the interior width of the boxlike portion 39, said opening being of such a size as to permit the pivot pin` element H to pass freely therethrough. The front plate of the socket member G, at opposite sides of the slot 4|, provides retaining ledges vor walls for the pivot pin H, and the space between said plate 38 and the back wall of the boxlike portion 39 provides a guideway 43 for the pivot pin H and accommodates the same for both rotary and sliding movement.

As will be evident, the hinge member F may be readily assembled with the hinge socket member G or withdrawn therefrom, when the rack section is properly tilted, the pivot pin element H being passed through the enlarged portion 42--42 of the slot 4|. This tilted position of the rack In order to disengage the hinge member F when in the position shown in this ligure, the rack is pulled laterally away from the wall I3 of the car, the pivot pin H passing freely through the enlarged portion of the slot 4 To engage the hinge member with the socket, the hinge pin is aligned with the enlarged portion of the slot by angularly tilting the rack section, as shown in Figure 8, and the rack section pushed toward the wall lli, thus entering the hinge pin through said enlarged portion of the slot. The rack section may then be dropped to the position `shown in Figure 6, thereby bringing the pivot pin H in backof the overhanging ledges of the platelike portion 38 of the socket member G and eifectively anchoring the hinge member to the socket. It is further pointed out that during swinging movement of the rack section the pivot of the hinge member is forced to slide lengthwise in the guideway 43 due to the fact that the outer Iend section of the arm 3l of the hinge member F forms a lever which rides on the floor of the car while the rack is being swung toward and away from the side wall of the car.

As shown in Figure 6, the oor rack section l2 is supported by the hinge means E in such a manner that it is reliably anchored to the car wall for swinging movement, either from horizontal to vertical position or from vertical to horizontal position, the pivot pin I-I being guided to slide lengthwise of the guideway of the socket G While having rotary movement on its axis, the hinge member F being removable only when in the position shown in Figure 8. As will be further evident upon reference to this ligure, the arm 3i of the bracket 39 is formed of such a contour that it is supported for outward and inward sliding movement toward and away from the wall I0 on a substantially fiat, straight, bearing surface 44 on the lower edge thereof, thus facilitating attachment and removal of the hinge member. The edge portion of the arm 3i beyond the at bearing surface il is curved, as indicated at 45, to provide a guide on which the arm slidingly rocks while the rack is being raised from the position shown in Figure 8 toward the position shown in Figure 9, and lowered to the position shown in Figure 8. The rolling rocking action thus provided eifectively holds the pivot pin I-I in the guideway of the socket member G, as the pin passes the enlarged portion of the slot 4I during upward and downward swinging movement of the rack section.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that .come within the scopeof the claims appended hereto.
