APPARATUS FOR LOADING FREIGHT OR THE LIKE Sulo M. Nampa, Detroit, Mich., assignor to Evans Products Company, Detroit, Mich., a corporation of Delaware Application January 5, 1944, Serial No. 517,049

9 Claims.

The present invention relates to improved loading apparatus for holding freight articles of different types in vehicles or storage spaces and, more particularly, to improved equipment of this nature having certain parts which are built into or combined with a vehicle, such as a railway freight car, or other storage space, and having certain other parts which are adjustably and variously cooperable with the built-in parts, the several parts of the equipment cooperating to hold (that is, for example, to brace, support or carry, space, wedge, or provide shelves, partitions, or bins for) a wide variety of freight articles. This application discloses and claims improvements upon and modifications of the structures disclosed and claimed in applicants copending applications Serial No. 434,357, filed March 12, 1942, and Serial No. 469,719, filed December 21, 1942, both since abandoned but replaced, respectively, by continuation applications, Serial No. 740,330, filed April 9, 1947, and Serial No. 121,424, filed October 14, 1949.

Applicants above-identified application Serial No. 434,357 discloses and claims certain features of a loading organization which, as specifically disclosed, comprises two series of upright supporting members arranged at the respectively opposite sides of, and permanently secured to, a freight car; wall members which are adjustably and removably supported by the uprights; and crossmembers' which are disposed to be supported at their ends by wall members at the opposite sides of the car, so that the cross members extend across the car. The cross members may be used to form or to support bulkheads, to form or support'decking arrangements, to support cooperating upright and horizontal members utilized to subdivide the storage space longitudinally, as well as for variety of other purposes, all as set forth with greater particularity in the'above identified application Serial No. 434,357. Applicants above-identified application Serial'No. 469,719 discloses and claims a system! which, in one sense, may be characterized as employing freight holding members (specifically cross bars) which are adjustable in length and which are also provided with supporting heads which are rotatablerelative tothe body of the corresponding member.

The'inventive features to be claimed in this application are, in a generic sense, applicable to a wide variety of different freight loading arrangements, but in amore, restricted sense and as to at least certain of their a'spects, they have particular utility when embodied in freight loading arrangements of the general type described above. In certain of their aspects, also, these inventive features provide improved combinations of freight loading elements, and in certain of their other aspects, they provide improved freight loading elements per se.

With the above as well as other considerations in view, the principal objects of the present invention are to provide improved freight loading arrangements which are simple in construction, sturdy, low in cost and in weight, and reliable and efficient in operation; to provide improved loading elements for use in such arrangements; to provide such arrangements embodying as an element a freight holding member having a body portion adapted to engage freight and having heads for cooperation with supporting structure, particularly characterized in that a tiltable connection is provided between each head and the body portion; to provide such arrangements wherein the tiltable connection embodies elements which permit at least a limited adjustment of'the length of the freight holding member; to provide such arrangements wherein the connections between the body portion and the heads enable the body portion to be rocked about its axis relative to the heads; to provide such arrangements wherein the heads are adapted for relatively rigid but releasable connection to supporting structures, and wherein the connections between the heads and the body portion are arranged to permit the heads to be universally tilted relative to the body portion, whereby to better accommodate the holding member to the shape or other characteristics of the freight articles;

and to generally improve and simplify the con struction and arrangement of freight loading systems.

Other and more detailed objects of the invention appear in the following description and in the appended claims.

Fig. 6 is a view in transverse section taken along the line 66 of Fig. 4;

Fig. 7 is a fragmentary view of a modification;

freight holding systems, and these features may also be embodied in various different constructions. The disclosure of these features in particular forms and as embodied in or used with particular types of loading apparatus is, COnSe-r quently, to be regarded in an illustrative and not in a limiting sense.

Referring first to Fig. 1, the illustrated arrangement comprises generally the upright supporting members 3!}, which are arranged in aligned series at the opposite sides of a freight car 32; the wall members 34, which are disposed at the respective sides of the car and are adjustably supported by and between adjacent pairs of uprights 30; and a series of cross members 36, some or all of which may embody the particular distinguishing features of the present invention. It will be understood that the uprights 3'0 preferably extend, in spaced relation, along each side of the car, from the associated door opening to the corresponding end of the car and that, if desired, both ends of the car may be similarly equipped.

As described in the above copending applicae tions, the uprights 30 may themselves constitute the vertical members of the car structure. Preferably and as shown, however, the uprights 3d are relatively wide, plate-like members, which are secured to the structural frame members of the car. It is preferred to use uprights 36 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 will 'also be understood, the uprights so may 'extend'from the -floor of the car entirely to the roof structure or, in case the unit weight of the freight to be accommodated is too large to permit loading of the car entirely to the roof,

the uprights 30 may extend only part way from the floor to the ceiling.

As is also described in detail in the aforesaid copending applications, the uprights are provided on their outer surfaces with vertical rows of evenly spaced tooth-like projections M), which and the relation of the parts is such thata particular wall member can be locked in any of a plurality of vertically spaced positions relative to a particular pair of uprights 30. In addition,

each wall member 34 is readily separable froma particular pair of uprights. Reference is here made to the disclosures of said copending appli cations for further details concerning the structural features of the uprights 30 and wall members 3a, which permit these features of adjustability and removability.

For cooperation with "the cross members or 7; quently, the ball "may move axially of the socket cross bars 36, the wall members 34 are provided along their upper surfaces with continuous series of evenly spaced rounded tooth-like projections 44. These projections are either formed integrally with or are rigidly secured to the upper surfaces of angle membersflfi, which form part of the wall members 34. The underside of the horizontal flange of each angle member #6 forms a holding surface for cooperation with the hereinafter described latching elements associated with the cross bars 36.

In practice, a relatively large number of the wall members 35 are preferably provided so that each bay (the area between adjacent uprights 30.) at each side of the car may be provided with several wail members. Since the individual wall members 34 are independently adjustable, any desired distribution of the wall members along the sides of the car may be provided. In certain cases, a staggered relation is utilized, in which the wall members in successive bays are at dif- Ierent elevations. In other instances, as where it is desired to furnish a car with platforming or decking, it is desirable to have a plurality of wall members, positioned in successive bays, at the same elevation so as to provide, in effect, a single wall member greater in length than the width of any one bay. When so disposed, the Wall members extend in continuous end-to-end relation, and the teeth thereon constitute a single continuous rack.

Referring now to Figs. '3, 4 and 5, as Well as to Figs. 1 and 2, the cross bars 36 are illustrated as comprising a central body portion anda pair of supporting heads 52. In the illustrated arrangement, the cross bars 36 are dimensioned to extend entirely across the car, and the body poi-- tions thereof are arranged for direct engagement by the freight articles. It will be understood that, if desired, the improvements of the present -invention may be incorporated in bars of other lengths such, for example, as the half bars described in the aforesaid applications, and .may also be arranged so that the body portions thereof accommodate interlocking means for engagement by related .freightholding members. Thus, the load to be engaged bythe body portion may either be a freight article or another freight holding member.

As shown, the body portion '50 comprisesa pair of wooden beams 54, which receive between them a reinforcing member 56 of Z-section. The beams 54 may be held together in any suitable-way, as by means of the bolts 58..

The respective ends of the body portion 50 are provided with sockets 60 and 62. The socket 60 comprises apair of metalli-cmembers ,6], such as forgings, disposed in back-to-back relation and welded together along the lineslfiii. Thesocket .60 is secured to the Z-bar 56 by weldin along the adjacent ends of the flangesof .the-latter, -.one such Weld line being indicated at "66. The opposed faces of the members 6] are recessedso that ,together they define a borehavingan enlarged portion 68 and. a smaller portion 10.

with annular enlargement, T6, which. is slidable and rotatable withinthe enlargedibore portion68. It will be appreciated that the collar 16 limits the degree to which the shank 14 and, conse- 60 and thus limits the degree to which the bar 36 may be extended.

In order to lock the body portion 50 relative to the shank 14, the stud 80 and the associated looking member 82 are provided. The stud 80 is received in a bore provided therefor in the members 6|. The lower portion of this bore is enlarged to receive the locking member 82, and the enlarged bore portion opens into the bore portion I0. One face 84 of member 82 is complemental in shape to the shank I4. As will be understood, by releasing stud 80,. the locking relation between member 82 and shank I4 is released- By tightening stud 80, member 82 is drawn up into tight engagement with the surface of the shank 14.

The left-hand socket 62 is constructed as described with reference to the right-hand socket 60 with the exception that the shank 14 associated therewith is not slidable lengthwise thereof. Instead, the shank I4 is provided with an annular groove 86, which receives an annular ring 88, which is secured within the associated socket. W'ith this relation, it Will be appreciated that while the shank I4 is normally rotatable within the socket 62, it is fixed in place axially thereof, all adjustments of the bar length being accomplished at the right-hand end thereof. If desired and as shown, a locking means comprising a stud 90 and locking collar 92 may be associated with the left-hand socket and these members may be arranged as described with reference to socket B0.

The two heads 52 may be and preferably are constructed as described in detail in the aforesaid copending applications, with the exception that the inner ends thereof are provided with sockets I00, which receive the previously mentioned balls I2. The sockets I may be formed of two similar members secured together in backto-back relation, as is indicated by the weld lines I02 and which members are recessed to define the I spherical sockets for the balls 12. Preferably, each socket is provided with locking mechanism illustrated as comprising a stud I I0 and a locking member II2. As in the previous instances, the stud III] is received in a bore provided therefor in the corresponding socket I00, and the member I I2 is received in an enlarged bore portion which opens into the space occupied by the associated ball 12. The locking member is provided with a spherdoidal surface which binds against and locks.

the associated ball in a fixed position relative to the socket when the associated stud II 0 is tightened.

As is described in more detail in the aforesaid copending applications, the heads 52 are provided with a jaw-like extension I20, the underside whereof is provided with a plurality of rounded tooth-like projections I22, which mate with the tooth-like projections 44 provided on the associated wall members 34. The heads 52 are provided with retractable latches I24, which may be rotated, by means of an associated stud I26, from the locking position shown in the figures, through an angle of 180, to a position in whichthey are retracted within the body of the associated head. When so retracted, the latches I24 enable the associated bar 36 to be rested upon the wall members 34. When so applied, the latches I24 may be rotated to the active position, in which they lie beneath the flange of the associated angle member 46. The latches thus hold the teeth I22 and 44 in mating relation and prevent movement of the bar 36 lengthwise of the members 34.

A limit to rotation of each latch I24 in an unlocking direction isafi'orded by a st p pin I28,

and an associated spring-pressed deten't I 30 yieldingly holds the corresponding latch in either the projected or retracted position.

The modified embodiment of the invention shown in Figs. 7 and 8 may and preferably does duplicate the construction just described with the exception that in this instance the illustrated right-hand head I30, instead of being provided with a ball receiving socket I00, is provided with a rearwardly extending shank I32, which terminates in an enlarged ball I34. The corresponding socket I36, which may be secured to the central body portion of the associated bar in the manner described with reference to the sockets 60 and 62, is provided with an enlarged bore portion I38 which slidably receives the ball I34 and a smaller bore portion I40, which accommodates the shank I32. It will be appreciated that bore portion I40 is sufliciently larger than the shank I 32 to accommodate the amount ,of universal movement of the head I32 which it is desired to provide. As shown, the bore I38 is elongated and is provided with a correspondingly elongated locking member I42, which may be associated with a pair of locking studs I44 in the previously described manner. Locking member I42, when released, enables the ball I34 to both swivel and move longitudinally of the bore I38, thereby providing both cooking and lengthwise adjusting movements of the head I30. When locked, the member I42 secures the ball I34 in a desired cocked, lengthwise and rotative position relative to the body of the bar.

As will be understood, the left-hand head may be arranged as just described, with the exception that, if desired, the corresponding bore I38 may be spherical in shape so that it will accommodate the axial rocking movements of the body of the bar relative to the associated head, and the cooking of the head, but will not accommodate the axial adjustment. This latter adjustment is afforded at the right-hand end of the bar and in most instances is not needed at both ends.

, It will be recognized from the foregoing that the bars 36 are characterized as having freight engaging body portions and supporting heads, the construction and arrangement of the heads being such that, when engaged with a wall member 34 and with the associated latch in place, only a limited amount of cooking of the heads relative to the wall members 34 is possible. Such limited cocking, which is afforded by the constructions of the aforesaid copending applications, is sufficient in many instances to accommodate the necessary cocking of the bar relative to the load. In other cases, a greater amount of cooking of the bar is needed. For example, with many freight loads, it is desirable to support one end of the bar considerably nearer the end of the associated car than the other end of the bar, or to support one end of the bar at a considerably different elevation than the other end of the bar, or both. The tiltable connections of the present invention readily permit such angular disposition of the bar, one of the bars 36 being shown in angled position in Fig. 1.

In use, it will be appreciated that after the desired number of Wall members 34 are applied to the uprights 30 (with the wall members at opposite sides of the car in either vertically aligned or vertically displaced relation, depend-.

ing upon the character of the freight articles) the corresponding cross bars 36 may be applied thereto by resting the ends of thebars upon the wall members and thereafter pushing the bars along the wall members to desired position. The rounded character of the tooth-like projections 44 and I22 enables such last-mentioned movement while thebars remain supported by the wall members. In case a particular bar is to be associated with wall members which are at the same vertical level, and further in case the bar is to extend straight across the car, such bar may be adjusted so that its heads are aligned with the body portion, and it may also be adjusted to the proper length and to have the proper rocked relation of the body (about its own axis) relative to the heads. In case the bar is to extend angularly across the car, either to accommodate difierent elevations of the wall members, or to enable one end of the bar to be located nearer the end of the car than the other,

or both, the heads may be loosened, tilted to the desired degree, and thereafter re-tightened. All

of these adjustments may, as will be understood, be made either before the bar is applied to the wall members or thereafter. Normal tolerances in the connections between the heads and the wall members enable final wedging movements of the bar, relative to the freight articles, to be accomplished by advancing the ends of the bar one at a time, it being understood that it is preferred to rely on the tiltable feature of the present heads to accommodate angularities in'excess of those required to accommodate the just-mentioned final wedging movements. When the final position of a particular bar is attained, the latches 24 associated therewith may be turned into latching position.

Although only two specific embodiments of the invention have been described in detail, it will be appreciated that various further modifications in the form, number and arrangement of parts 'may be made without departing from the invention. It should be noted that in the foregoing description and in the claims the word tilt is used to mean angular inclination of the axis of the head relative to the longitudinal axis of the body as distinct from merely relative rotation between the head and body about said longitudinal body axis.
