As aforesaid, it will be appreciated from a cornplete understanding of the inventive features to be claimed in this application, that in a generic sense they may be embodied in or used with a wide variety of freight holding systems, and these features may partake of various different constructions. The disclosure of these features in particular forms, and as embodied in or used with particular types of loading apparatus, is
consequently to be regarded in an illustrative and not in a limiting sense.
Referring first to Fig. l, the illustrated arrangement ccmprises generally corresponding series of upright supporting members arranged in aligned relationship at the opposite Sides of a freight car 32; a series of wall members 34 which are disposed at opposite sides of the car and are adjustably supported by and between adjacent pairs of uprights 3i); a series of cross members 5t, the length whereof is adjustable, as described below; and a cross member 38, the length whereof is adjustable, but which also comprises a rotatable mid or freight-engaging seotion 4b. It will be understood that, if desired, both ends of the freight car may be equipped as indicated for the one end in Fig. 1 and that, in fact, in usual practice both ends would be so equipped. A description of the equipment for one end of the car is thus thought to be sumcient.
As described in the parent application, the uprights 39 may themselves constitute the vertical members of the car structure. Preferably and as shown, however, particularly in Fig. 4, the upi rights 30 are relatively wide plate-1ike members, which are secured to the inner faces 42 of the corresponding car uprights 44. As shown in Fig. a, these uprights 44 are of usual outwardly presenting channel form, having outwardly turned flanges 46 to which the outer paneling 48 of the car is secured, as by means of rivets 5D. It will be understood that the uprights 44 may be conventionally secured to the loor and roof structures 52 and 54 of the car. The uprights 3D are illustrated as being welded, as indicated at 56, to the associated car uprights 44, and it will be understood that the welded joints may extend continuously or interruptedly throughout the full length of the uprights 3D. It is to be noted that it is preferred to use uprights 33 of relatively heavy metal, so that these uprights, in addition to affording a support for the cooperating freight loading elements, also serve to reinforce and strengthen the car structure as a whole.
As shown, the uprights 33 extend from the floor of the car entirely to the roof structurey although it will be understood that for certain classes of loading, in which the unit weight of the freight is too large to permit loading of the car entirely to the roof, the uprights 30 may be extended only part way from the floor to the ceiling.
For cooperation with the hereinafter described wall members 34, each upright 30 is provided on its outer face with two vertical rows of evenly spaced, toothlike projections 60, the crowns and roots whereof are preferably of rounded form and which projections 69, consequently, are of racklike form. This construction alfords, as described below, a very efficient, adjustable connection between the wall members and the uprights, which allows a very close spacing, for example, one-half inch, between adjusted positions. Teeth 6G may be variously applied to the uprights 3Q, and are illustrated as formed separately therefrom on convenient lengths 5I, which are secured, as by welding, to the uprights.
It will be understood that preparatory to the installation of the uprights, it is preferred to remove the usual wood paneling or lining of the car, which lining normally affords a buffer surface for the freight. In order to provide such a buffer surface, it is preferred to maintain the inner surfaces of the uprights 33 free of projecting portions, and it is further preferred to secure panels, such as G2, to the car walls, in the spaces between the uprights 30, the inner faces of the panels 62 being substantially flush with, but projecting slightly inwardly of, the surfaces of the uprights 3i). The panels 6-2 may be formed of wood or other like material and, desirably, may be provided with graduations or markings 64 so as to facilitate the location of the wall members, at opposite sides of the car, at the same elevation. In order to accommodate the cross members 311, a space designated a in Fig. l is left between the opposed edges of each upright 30 and the adjacent panel 6.2. Various means for securing the panels 62 to the car structure are described in the parent application and need not be described here.
Referring particularly to Figs. 1, 3, 5, 5A and '7, the wall members 34 are illustrated as comprising generally an angle member 76, the longer flange 10a whereof is arranged vertically and the shorter flange lllib is arranged horizontally. The shorter flange 10b is provided on its upper surface with a series of tooth-like projections 60, which are similar in form to the previously mentioned projections and which may, in fact, be identical therewith. As shown in Fig. 3, the

'In practice, Aa'relat-ively large number offthe -wall members'd are preferably lprovidedfso that each bay (the w area between adjacent .upr-ights .30) ateach side of the'car may. beprovidedwith several wall members. Since the individual wall Ymembers 34 -fare independently adjustable, any
`desired'distribution of the lWall members along the sides of the car may be-provided. .In certain cases, the staggered relation-shown in :most-instances-.in Fig. 1 is utilized. .In other instances, yas where itis desiredto furnish-a car withplatforming or decking, vit is y,desirable to have-a plurality of Wall memberapositionedin. successive .bays'at the same elevationso .asto-.providegin eiect, asingley wallfmembergreater in length than the ywidth of..anyV one bay.
.One of. the .cross .bars .2- is shown` in'. detail .in Figs.. 8.through.12. The intermediate` portionl i100 of themain lengthof the bar is preferably. formed of .wood .so as to present a .satisfactory "'bufier surface"tothe.freight articles engaged thereby and while such intermediateportion mayjif desired, be formed of a. single piece of Woodyitls preferredto `formit of two .similar strips i102 and 104,*which-it will .be vnoted are ...continuous and extend:throughout"substantially the' entire'length of the bar. Also itiwill'be notedthatithelus'e of 'one-piece or"continuouswooden' members, crappreciable cross-section, are simpler and give greater beam strength per unit weight than would be provided by several pieces connected end to end, or by metal pieces interrupted by telescopic and/or swivel fittings. These wooden strips |52 and |04 are stiffened and separated by a steel Z- bar |06, which, as will be understood, may be rolled or otherwise formed into shape. Member |06 has a web portion |01 and oppositely disposed side flanges |08, which extend toward, but not quite to, the edges of the strips |02 and |04. Thus, there are two complete faces of the bar 36 in which there is no exposed metal to injure freight. As to the other two faces, the metal flanges |03 are either fiush with or are slightly behind the wooden surfaces |04a and |02a. Members |02, |04 and |06 are secured together by carriage bolts having heads ||2 and nuts ||4 recessed or countersunk in suitable recesses in the wooden members. bar 36 are provided with heads or jaws |20 and |22, which may be and preferably are identical to each other except in the hereinafter mentioned respects which enable the head to move telescopically into or out of the body of the bar so as to enable the length of the bar to be adjusted.
The head or holding unit |20 comprises a generally U-shaped steel member |24. The base portion of member |24 has a tubular stub shaft |25 secured thereto as by welding. A relatively heavy member |28, which may be a steel casting but is preferably a forging, and which is provided on the underside of its outwardly projecting portion with a series of tooth-like projections |32, is secured within the U-shaped member |24, as by welding along the line indicated at in Fig. 8.
The member |28 is provided with a stifiening rib |36 which extends across its top surface and is provided with an enlarged central bore which receives the post |38. The recessed areas |40 and |42 at either side of the rib |36 may be provided with suitable indicia, such as the arrow and the words Lock and Open, to indicate locking and unlocking positions for the arrow |42 on the top of the post |38. The underside of member |28 is substantially flat except for the previously mentioned outwardly projecting portion which carries the downwardly presenting tooth-like projections |32. of teeth |32 may be utilized, seven being illustrated in Fig. 8. It will be understood, of course, that these teeth are complemental in form to the teeth on the upper surfaces of the wall members 34, so as to enable them to mesh therewith.
The outer ends of the several teeth |32 are joined together by a rib-like member |44 which, consequently, closes the outer ends of the grooves between the several teeth |32. The rib |44 is thus effective to interlock with the ends of the several teeth 60 which mesh with the teeth |32 and prevent axial movement of the head |20 to the right` relative to the member 34, as viewed in Figs. 8 and 9. The other ends of the grooves between successive teeth |32 are closed by the adjacent body portion of the member |28, as is indicated at |46, which body portion, consequently, serves to prevent or limit movement of the head |20 to the left relative to the member 34.
It will be appreciated that in view of the rounded character of the teeth 60 and |32, the cross members 36 may, after having been seated upon the cooperating oppositely disposed members 34, be pushed lengthwise of the members The respectively opposite ends of the Any suitable number 8 34, during which movement the cross bar 36 moves vertically sufficiently to enable the crests of the 4 teeth |32 to ride over the crests of the teeth 60.
In order to prevent vertical dislodgement of the bar 36, there is provided a rotary latch |50, which is either formed integrally with or is fixed to the lower end of the previously mentioned post |38, and the upper end whereof is formed as a hex nut |52, for engagement by a suitable wrench. The latch |50 may also be a forging. The periphery of the body of the latch |50 is shaped, as
-shown in Fig. 8, to have an arcuate portion |54 a nat portion |56. The portions |54 and |56 are joined together by curved portions which define two recesses |58 and |60 for cooperation, respectively, with a stop pin |62 and a detent |64. The stop pin |62 is fitted into the member |28 and projects downwardly for cooperation with the just-mentioned surfaces. The detent |64 comprises a ball which is received in a pocket |66 in the member |28 and is urged to the position shown by a spring |10. The parts are shown in Figs. 8, 9 and l0 in the locked position, in which the rounded locking portion having the surface |54 is disposed below and in substantially abutting relation to the underside of the flange 10b on the cooperating wall member 34. In this position, the pin |62 engages the surface |60 and prevents further rotation of the latch member |50 in a clockwise direction, as viewed in Fig. 8. fn this position, also, the detent |64 engages the surface |58 and yieldably resists rotation of the latch member |50 in a counterclockwise or unlocking direction. It will be understood, however, that by rotating the nut |52 in a counterclockwise direction, the latch |50 is correspondingly rotated, during which rotation the detent |64 rides along the upper surface. 180 of such rotation brings the latch |50 to the unlocked position in which the pin |62 cooperates with the surface |53 to prevent further such rotation, and in which the detent cooperates with the surface |60 to yieldably hold the latch |50 in the unlocked position. This unlocking movement brings the member |50 out from under the flange 10b on the Wall member 34 and enables the corersponding end of the bar 36 to be freely lifted away from the wall member.
After the latch |50 and the above described cooperating elements are assembled in place relative to the member |28, a supporting plate |1| is welded or otherwise secured to the legs of the U--shaped member |24.
In order to enable the cross bar 36 to be freely adjustable in length, so as to accommodate variations in the width of the car, the previously mentioned tubular post |26 is telescopically received within a fitting comprising two relatively short channel members |12 and |14, which are secured together, as by welding at the points |16, in back-to-back relation. The wood strips |02 and |04 are extended beyond the corresponding end |05a of the Z-bar |05. A leg of the channel member |12 thus abuts the end of one flange |08 of the Z-bar and the opposite legs of the other channel member |14 thus abuts the end of the other flange |08 of the Z-bar. These abutting joints may be completed by welding or otherwise, as will be understood, and, as shown, throughrods |50 may be passed through the strips |02 and |04 and through the flanges of the members |12 and |14 to secure these parts together.
The webs of the channel members |12 and |14 are provided with semicircular portions and locking cam 214, which cam may be and preferably is arranged to be vertically slidable within the opening 212, but is not rotatable therein. The bore 212 opens into the cylindrical sleeve which receives the post 256, and it will be understood that by turning the stud 212, the cam 21d may be drawn upwardly into solid engagement with the surface of the post 255, whereby to clamp or lock the post 256 between the cam 21s and the sleevelike surface on the upper socket portion 255i. The post-engaging face of the cam 214 is complemental to the portion of the post engaged thereby.
The socket 262 may be and preferably is secured to the body of the bar 32 in the manner described for the connection between the socket members |12 and |14 and the body |62 of the bar 36 (Fig. 8).
The right-hand head 252 may be and preferably is constructed as described in connection with the head 252, with the exception that the post 280 associated therewith is of greater length and is provided at its extreme left-hand end with an annular rib or enlargement 282. The post 280 and the rib 282 are received in a socket 2813, which may be and preferably is formed of a single forging. The socket 284 is provided with a bore 285, which snugly but slidably receives the body of the post 280 and is also provided with an enlarged counterbore 288, which snugly but slidably accommodates the annular rib 282. A limit to the inward movement of the head 252 relative to the body of the cross bar 38 is afforded, lof course, by the abutting engagement between the back of the head 252 and the right-hand end of t the socket 284. Similarly, a limit to the lengthening movement of the bar is afforded by the engagement between the annular rib 222 and the right-hand end of the counterbore 28B. It will be understood that the head 252 and the socket 284 may be assembled together by iirst passing the post 280 axially through the socket and by thereafter securing the rib 282 to the post 23B by welding along the joint 290. After the members 252 and 284 are thus assembled together, the socket 2M may be secured to the body of the bar 38 in the manner described in connection with the socket 252.
The modified construction of rotatable cross bar 350, shown in Figs. 20 through 24, may and preferably does duplicate the construction of the bar 38 in many respects. In Figs. 2O through 24, however, the socket members 30| and 322 are formed of stampings instead of being formed of forgings. More particularly, the socket 30! is formed of a pair of channel-shaped stampings I 304 and 325, suitably secured, as by welding, to each other in back-to-back relation. rihe webs of these stampings are provided with semi-circular grooved portions 303, which together define a cylindrical sleeve to slidably receive the post 3H) associated with the head M2. As in the previous instance, the post 3 l 0 is provided with an annular recess 312, which receives ribs 3 l provided in the grooves 308. If desired, the ribs 314 may be pressed from the bodies of the stampings 304 and 30S, although, as shown, separate ribs 314 are welded in place within the semi-circular grooves. The head SI2 is thus freely rotatable relative to the socket 300, but is not adjustable axially thereof.
The socket 352 is also formed of a pair of opposed channel members 32d and 322, which are provided with grooved portions 324, which define a sleeve which slidably receives the body 325 of the post associated with the head 328. The extreme end of the post 328 is, as before, provided with an annular rib or enlargement 33B, which is slidably and rotatably received in the enlarged cylindrical sleeve-like portion defined by the deeper grooved portions 332.
In this instance, the locking member 34@ is shown as being applied between the body of the cross bar and that one of the heads which is both rotatably and axially adjustable. The locking means may be similar to that described above and, consequently, has not been shown in detail.
It will ce noticed that with the construction of Fig. l5, the locking of the unit in a selected or rocked position does not interfere with the free adjustability of the length of the bar. This relationship is advantageous in many instances, since it enables the bar to be fitted' to various different car widths, and further enables the bar to automatically change in length to accommodate slight variations in car width which occur in transit. On the other hand, it is in certain instances advantageous to utilize the cross bars to give crosswise reinforcement to the car so as to prevent changes in car width which would normally tend to occur in transit or during shunting operations. In such cases, the construction of Figs. 20 through 24 is particularly advantageous, since when the bar has once been located at a desired point along the car and has also been rocked to the desired degree, the locking action xes not only the rocked position, but also the length of the bar, and enables it to reinforce the car, as aforesaid. It will be appreciated that this locking feature may also he utilized to advantage in constructions which, while having the feature of adjustability as to length, do not necessarily embody the rockable feature.
It will be appreciated that the above described rotatable features may also be embodied in the special types of bars shown in Fig. 2, in which figure the bar 38' is provided along its length with the teeth El! in the manner described in connection with the bars 39.
Before proceeding to a summary of the operating characteristics of the herein disclosed embodiment of the invention, attention is directed to the wedging tool shown in Figs. 24 and 25, and' which may be conveniently used to advance the cross bars along their associated supporting members, such as the wall members 34, so as to enable the wedging of the freight articles in place.
Referring particularly to Figs. 25 and 26, the wedging or leverage tool shown in use in Fig. 25, and in more detail in Fig. 26, is designated as a whole by the numeral 350 and comprises a suitable handle 352 suitably secured into a short sleeve 354 which is secured, as by welding at 355, to the side or main frame plates 356. These relatively heavy stiff plates are rigidly spaced apart by these welds and by pin 358 which is secured into holes 350 in each plate and also serves as a pivot for the freely rotatable sliding roller sleeve 352. The forged steel jaw member 364 is generally U -shaped with opposing faces and with two opposedl sets of identical curved teeth 35S, which are just like and meshl with teeth tt. As will be seen, this one tool with its two opposed sets of teeth can be used on the right or left-hand sides of the car. The space between the two sets of teeth 326 corresponds to the thickness of upper or shorter leg of the angle 10 plus the thickness of rack 60, or the equivalent member. The member 366 is freely pivotally mounted in, and also secured between, plates 35S by pins 368 in holes acre-em The. manner. of, .usinglthe wedging ytool?. 3.50.'. is-fshowninFig. 25....

The construction of the individual members is advantageous in resisting beam loading, since the reinforcing members therefor, being flanged, strengthen them against both vertically and horizontally applied forces. In this connection, also, it will be appreciated that the relatively long telescopic connections are'of material advantage, since these connections `afford relatively long bearing surfaces along which the beam forces are distributed.
Although only several specific embodiments of the invention have been described in detail, it will be appreciated that various further modiflcations in the form, number and arrangement of the parts may be made without departing from the spirit and scope of the invention;
