(Cl. IOS-e369) 11 Claims.

This invention relates toapparatus for bracing the load of railway freight cars or the like. Apparatus of this type is known in the trade as utility loading apparatus.

It is an object of the present invention to provide apparatus for bracing a load which is characterized by its adaptability for use in bracing a large variety of sizes and shapes of loads without requiring the fabrication of a large number or bracing members of the proper size for each application.

Present day utility loading or adjustable car bracing mechanisms are objectionable in that they require the use of special bracing members having permanent attachments carried thereby' and require that a complete set of bracing members with their special attachments be carried in the car at all times. This apparatus is often very heavy and in some instances adds as much as one-third or more to the weight of the car when empty, thus substantially reducing the pay load that can be carried when the car is so equipped. It is therefore an object of the prescnt invention to provide an apparatus for adjustably bracing the load which does not require carrying a large supply of heavy bracing members. The apparatus of the present inven` tion is constructed so that the fixtures for supporting the bracing members are built into the construction of the car and it is possible to utilize ordinary bracing members of dunnage lumber available at the point where the car is loaded.

Another object is to provide apparatus for bracing loads which will not interfere with normal use of the car in the event that the character of the load does not require bracing apparatus.

A further object is to provide utility loading I apparatus in which all parts of the vapparatus are permanently attached to the car so that the movable parts thereof cannot become detached from the car and thereby be lost.

A still further object of the present invention is to provide apparatus for bracing a load vof a railway box car or the like in which the apparatus is constructed as a part of the side wall structure of the car so that the apparatus when not in use can be carried within the car side wall without hindering free use of the car. Other objects and advantages of the present' invention will become apparent from .the following detailed description accompanied-by' the drawings, in which:

They present invention is shown in combination with an improved car side construction which is moreV particularly described and claimed in my co-pending application, Serial No. '773,898 led September lf3, 1947, entitled Car Side Construction and Load Bracing Apparatus.

The preferred form of car side construction shown in t'hedrawings with which the present invention may be utilized comprises side post members i longitudinally spaced along the two opposed car side walls and extending vertically between side plate 2 at the top of the car and side sillV 3 at the bottom of the car. These side post'members vpreferably have a multiple channel' configurationl in cross section with at least one channel facing the interior of the car to provide a vertical recess 4 opening into the interior of the car. The outer car wall may be formed from suitable sheathing panels 5 which may overlap in the region of the side post members.. The side post members l may be provided with flange portions d which lie adjacent the sheathing panels 5 and afford relatively wide contact areas for secure attachment of the sheathing panels tothe side post members.

As may best' be seen' in Fig. e, the side post membersl may be integrally formed along one verticalv side edge ofeach of the sheathing panels 5. The opposite side edge of the adjacent sheathing panel may the-nl overlap the Side post me'nr'lloer Vand be secured thereto.- in combination with .the multiple channel side post construction, .the voverlapped ,shea-thing panel forms enclosed tubular lcolumn members which provide a very sturdy and rigidV car side construction highly resistant to `forces tending to bulgeY the oar side outwardly; The sheatlfiing panels 5 land side post-members Iv provide the strength bearing members 4of the side wall construction.I

Suitable furring or nailing strips 'I may be provided to which may be secured a lining 8 forming a smooth interior surface of the car side Wall. Preferably the lining 8 is disposed so that it is substantially iiush with the inner extent of the side post members I so that a continuous smooth faced wall is provided. To hold the nailing strips 'I in place, angle bars II! may be Secured to the sheathing panels 5 or the side post members I in any suitable manner and the nailing strips 'I may be secured to the angle bars I by bolts or screws. If desired, side post members I may be further stiffened and strengthened by the use of suitable stiffening elements 9 which may comprise channel shaped members disposed transversely within the vertical recesses 4 at suitable intervals and secured to side walls II of the recesses 4 by welding or the like.

A preferred form of the vertical recesses 4 may be seen in Fig. fi in which the side walls II of the recess converge toward the interior of the car for a purpose to be explained presently. It is to be understood that although a preferred form of side wall construction is illustrated in the drawings, a railway car embodying the present load bracing apparatus may be constructed in any desired manner to provide the plurality of vertical recesses disposed at opposite longitudinal points along the car side and opening into the interior of the car.

Each of the recesses 4 carries one or more arms I2 which are mounted for vertical movement along the recess and also for rotary movement about a point near one end of the arm so that the arm may be disposed at any desired angularity with respect to the recess at any vertical point along the recess. The drawings illustrate one desirable method of mounting the arms I2 to achieve this movement.

A clamping member I3 is disposed within the recess I and has a stud or bolt Id projecting from the face of the clamping member centrally of the recess and toward the interior of the car. At either or both sides of the clamping member I4, friction clamping shoes I may be mounted for limited pivotal movement. In the form of the invention shown in the drawings the clamping member terminates in angularly disposed cylindricai surfaces I which may be embraced by complementary shaped surfaces lying between arms I 'I of the friction Shoes I5. To hold the friction shoes I5 to the clamping member I3, the top and bottom ends of the clamping members I3 may be provided with headed portions, indicated by the numeral I8.

` The arm I2 is provided with a frusto-conical projection 2i), the diameter at the base of the frusto-conical projection being approximately the width of the opening of the recess 4 and the top of the irusto-conical projection being apertured to receive the bolt or stud I4. Thus, when it is desired to lock the arm I2 at any desired vertical point, nut 2I is tightened, drawing the clamping member I3 and the friction shoes I 5 toward the mouth of the converging recess along the side walls II. The arm I2, having portions lying across and extending beyond the mouth of the recess d, resists being pulled into the recess and a secured clamping action is provided. This position is shown best in Fig. 6.

The arm I2 is a channel shaped member having side portions 22 and a connecting base portion or bottom wall 23 from which the frustoconical projection 2D extends. The width of the arm I2, except for enlarged flange portions 24 on the channel sides 22, is less than the width of the mouth of the recess li so that in either its upward or downward vertical position the arm I2 may be substantially entirely disposed Within the recess 4 and by further tightening of the nut 2| the arm may be clamped within the recess. In this position, illustrated in Fig. 3, the only portion of the load supporting apparatus projecting beyond the interior surface of the side wall are the fiange portions 24 of the channel legs 22, so that when the arms I2 are not in use they may be stored within the car side wall where they do not interfere with the normal use of the car. Each of the channel legs 22 of the arms I2 is provided with a longitudinally extending recessed portion 25 and extending along this recessed portion in the region of the bottom wall 23 are a plurality of notches 26 which open to the recessed portion 25. Mounted for sliding movement along the recess 25 between the channel legs 22 is a locking member 2l having outwardly extending pins 28 which may be adjustably positioned in the notches 26 or may be Withdrawn from the notches 2t and moved along the recess 25 to a desired position. The channel legs 22 of the arm I2 are spaced apart suicient to receive the end of suitable transverse bracing member 29. 'The purpose of the locking member 21 is to hold an end of the transverse bracing member 29 in contact with a portion of the load so that it will restrain shifting of the load while the car is in movement, and for this purpose the locking member is provided With a head 3U having wedge or cam surfaces 3l thereon which permit the locking member to be used in either direction.

In operation the load to be braced is placed in the car and the desired number of arms I2 are positioned in approximately the correct location for bracing the load. The transverse bracing members are positioned in contact with the load with their ends disposed between the channel legs 22 of two opposite arms I2 and the locking member 21 is moved along the arm until the wedge surface 5I contacts the bracing member 29. The pins 28 of the locking member may then be inserted in the next closest notch 25 and by applying pressure to the head 3U, the wedge or cam surfaces 3i are used to tightly wedge the locking member 2i so that it will hold the bracing member 29 firmly against the load.

As may be seen in Fig. 1, each of the railway car sides at opposite points therealong is provided with a number of the vertical recesses 4 in which are mounted a plurality of fixed and a plurality of adjustable means for supporting transverse bracing members. The nxed supporting means are provided by the stiffening elements 9 and the adjustable supporting means are provided by the rotatable arms I2 and their associated mechanism. The iixed supporting means are disposed within the car side wall construction and the adjustable supporting means may be locked in a position within the car wall when it is desired to utilize the car without the load bracing apparatus.

Fig. 1 illustrates several applications of the present invention embracing the load of a railway box car. The numeral s2 indicates objects disposed on the iioor of the car and held in place by a transverse bracing member 29 supported each of its ends by one of the arms I2. `The numeral 33 indicates a removable floor or deck supported by a plurality of transverse bracing members 29, which in turn are supported at their ful to tier the car so that it may carry objects atV separated vertical heights. The numeral 34 indicates a large object carried by the oor 33. The object 3d is held in place by a transverse bracing member 29 supported in position by a pair of the arms I2. An additional bracing member is locked into place against an angular surface of the object 34 as indicated at 3e to more firmly hold the object in place.

Fig. 8 illustrates a modified form of side wall construction utilizing side post members 40 which are similar to those shown in Figs. 1 through '7 except that the side post members 40 are not integrally formed with the sheathing panels. Instead sheathing panels l are provided and it is preferable that the edges of adjacent sheathing panels meet in a lap joint in the region of the side post members so that the sheathing panels may be secured to each other and to flange portions 42 of the side post members 40.

Fig. 9 illustrates the application of the present invention to existing railway freight cars. When the lining of an existing car becomes worn and is removed for replacement, side post members constructed in accordance with the present invention may be readily installed in the car side wall and will provide a strengthened and stiffened car side wall, while at the same time incorporating the improved load bracing apparatus of the present invention. In Fig. 9 the numeral 5l indicates the conventional Z-section side post which may be found in a large number of existing box cars. Two adjacent sheathing panels 52 meet in a joint in the region of side post 5I and may be secured to such side post member. Unless the sheathing panels are defective they need not be replaced. New side post members 53 constructed in accordance with the present invention may be installed in the car side wall at opposite points along the car side wall and may be secured at their ends to the side plate and the side sill and to the sheathing panels along the flange portions ll which lie adjacent the sheathing panels. Then new nailing strips or furring 55 may be suitably secured to the side post members 53 and a suitable interior lining 56 nailed to the nailing strips 55 so that the lining will provide an interior car side surface substantially flush with the side post members 53. Thus a plurality of channel shaped recesses 57 opening into the interior of the car are provided in which may be mounted a plurality of stationary transverse bracing member supports 58 and a plurality of the previously described adjustable bracing member supports or rotary arms (not shown). When completed the car is provided with a reinforced car side construction of great strength and stiffness. Further, the car is equipped with load bracing apparatus embodying the present invention.

Utility loading apparatus constructed as previously described provides a highly advantageous means for bracing the wide variety of loads encountered in railway freight cars. The present invention obviates the serious disadvantage encountered in previous mechanisms of this type, namely, the bulk and weight of the removable load bracing attachments which are required to be carried in the car for possible use whether or not they were needed. In the present construction 'a portion of the apparatus is permanently installed within the car side wall and cannot be removed and thus be lost or misplaced. The

balance of the load bracing apparatus comprises bracing members which may be of wood and obtained at the site Where the loading is to be done. In fact, in the case of the transverse bracing members 29, these may be cut to the proper length and an available supply maintained.

When it is desired to use the car without the apparatus, the apparatus can be locked into the car side wall where it will not interfere with the use of the car. By the use of fixed load bracing supports and the adjustable arms, almost any shape or size of load can be eifectively braced, eliminating the time consuming method of cutting and fitting dunnage lumber for each article to be braced. With the present apparatus there is little or no occasion to nail bracingmembers to the lining or floor of the car wall and accordingly the lifev ofl these parts is materially increased.

Load bracing apparatus and car side wall construction embodying the present invention and constructed as shown Iand described is highly advantageous in affording an exceedingly strong and sturdy side wall construction for railway freight cars. The form of side post member shown in the drawings is of greater longitudinal extent than side post members now in use. rlhis means that the portions ofthe side plate 2 and the sheathing 5 disposed between adjacent` side post members are of less extent and the strength of the walls is increased without increasing the cost and weight of the construction by an increase in the number of side posts. The decreased extent of the side sill portions between adjacent side post members provides a stiffer and stronger car side frame and the decrease in length of sheathing between side post members provides a stiffer'car side wall construction with an increased resistance to forces tending to bulge such side walls.

It will be understood that the foregoing description of preferred embodiments of the invention is for the purpose of explanation and illustration and is not intended to limit the scope of the invention as described and claimed in the following claims.
