Appiication July 14, 1941, Serial No. 492,342

8 Claims.

The present invention relates to apparatus for packing or stowing objects of irregular shape in containers for shipment, and constitutes an improvent on the shipping apparatus forming the subject matter of pending application Serial No. 325,727, filed March 25, 1940. The embodiment of the invention herein described and illustrated is designed particularly for packing certain parts of automobiles in boX cars for railway shipment, although it may also be used without essential change for the packing of other objects of generally similar shape in other shipping vehicles or containers.

The principal objects of the invention are to provide means for stowing the greatest possible number of objects in a given space; to hold each object securely and rigidly in order to prevent shifting and damage during transportation; to provide apparatus which can be quickly and easily installed in a car during the loading of the articles to be shipped; and to provide apparatus which can be adapted to the stowing and holding of articles of different sizes. Other objects and advantages of the invention will become apparent from the following description of a preferred embodiment thereof, which should be read with the understanding that changes within the limit of the claims hereto appended may be made in the form, construction and arrangement of the various parts, without departing from the spirit of the invention.

In the automobile industry, it is customary to ship large numbers of parts or assemblies of parts from the factory to assembly plants. One item which is handled in this manner is the steering gear assembly consisting of a housing containing the worm gear and a comparatively long shaft extending from said housing and rigidly connected with the worm therein. Because of the length of the long shaft and the necessity for preserving accurate alignment of the various parts these steering gear assemblies are awkward and difiicult to ship successfully. It is for this purpose that the apparatus herein described has been designed.

The housing or body portion of the steering gear assembly is relatively heavy, and the shaft, although much lighter, is subject to damage through bending unless it is properly supported. The present invention contemplates the stowing of the steering gear assemblies in banks, the housings or body portions being piled in a tier of horizontal rows extending across the car or container, each row supported by the row next below, with a suitable spacer and retainer bar of, and 8 are side walls.

between said rows to prevent shifting longitudinally toward the ends of'the container. The shafts of the steering gears are positioned at a steep incline, directed upwardly and toward the end of the container. By thus steeply inclining the shafts, the bending forces acting upon them are reduced, and they can be supported adequately, each row by the row next below, with a spacer bar between said rows. The weight of the shafts is borne partly by the gear housings and partly by the tier of spacer bars.

In the accompanying drawings:

Fig. 1 is a longitudinal section of a portion of a freight car, showing one bank of steering gears stowed therein, and supporting members in position to begin the stowing of a second bank.

Fig. 2 is a transverse section of a portion of the car, showing two rows of steering gears stowed in one bank.

Fig. 3 is a transverse section of a portion of the car showing one complete bank of steering gears stowed therein.

Fig. 4 is a sectional plan of a corner portion of the car, showing the vertical guides for one bank.

In the drawings, the reference numeral 6 designates the floor of a freight car or other ship- 7 ping vehicle or container, 1 is an end wall there- Secured to the side walls are plurality of channel guides 9 and I0, preferably vertical but not necessarily so, as they may be slightly inclined. Alternate guides 9 extend from the floor upwardly, and the intervening guides H3 extend downwardly from near the roof (not shown). This arrangement of the vertical guides, however; is merely for the purpose of saving material and weight, and if desired, all said guides can be of the same length, extending from the fioor upwardly nearly to the roof. The vertical channel guides 9 and If! on opposite side walls are preferably directly opposite each other.

A cross bar II is laid on the floor, extending between two opposite channel guides 9, with its ends engaging said guides. A transverse channel member l2 islaid upon said cross bar with its channel side up. The width of the channel cross member I2 is such that its ends fit into the vertical channel guides -9, by which it is heldv against movement longitudinally of the car.

Near the bottom of the vertical guides it are fixed brackets or stops, one of whichis shown at l3. A bar M is placed across between opposite vertical guides Ill, its ends fitting into the channels thereof. A reinforcing angle bar 15 is secured to the lower side of the bar I4 and supports it in inclined position as shown, the ends of said angle bar I5 resting upon the brackets I3. A column I B, removably mounted in a socket I! in the floor 6, supports the central portion of the bars I4 and I5.

With one channel bar I2 and one bar I I in position in their respective guides 9 and If), as shown at the right in Fig. 1, a row of steering gears is stowed. Each gear assembly, as shipped, has an irregular housing or body portion I8 and a long shaft I9 extending therefrom. The gear housings I8 are placed side by side upon the channel bar I2, and the shafts I9 are inclined upwardly and rearwardly toward the end of the car and rest against the inclined bar I4, as shown at the left of Fig. 1 and in Figs. 2 and 3. The upper side of the bar M is provided with cushions 2a, preferably two in number, one near each edge, and formed of continuous strips of rubber, half-round in cross section.

When one row of steering gears has been stowed, extending all the way across the car, a second channel bar I2 is placed between the guides 9, resting directly upon the gear housings l8 of said first row. A spacer bar 2| is placed between the guides I 0, resting upon the shafts I9. The spacer bar 2| is similar to the bar I l except that it has cushions on both sides, and does not have the reinforcing angle bar I5. The bars I4 and 21 are preferably made of wood, rectangular in cross section, with metal shoes (not shown) at their ends where they engage the guides m.

A second row of steering gears is then placed 7 on the second bars I2 and 2!, their housings I8 resting in the channel I2 and their shafts I9 resting upon the spacer bar 2|. The same stowing is repeated, row upon row, until the bank is full. Each row of gear housings I8 is separated from the adjacent rows by a channel bar I2, and each row of shafts I9 is separated from the adjacent rows by a spacer bar 2!, but the weight of the entire bank of gear housings I8 is supported by the cross bar II resting directly upon the floor of the car, and the weight of the entire bankof shafts I9, or rather the vertical component thereof, is supported by the lowermost bar M. That is to say, each row of steering gears is supported by the next lower row, the bars I2 and 2f acting merely as spacers, and in the case of the bars I2, to prevent shifting movement of the housings I8 toward the ends of the car.

At the top of the bank of gear housings I8,

a hold-down bar 22 is placed across between the I guides 9. Said hold-down bar 22 is preferably rectangular, and preferably has a pad 23 of resilient material, such as rubber, on its lower surface which is in contact with the gear housings I8 of the topmost row. Similar cushioning pads (not shown) may be secured to the lower surfaces of the bar I2. The hold-down bar 22 is drawn down and held tightly against the top row of steering gears I8 by any suitable means, herein illustrated as eccentrics 24 secured to the side walls of the car, operated by hand levers 25. and connected withthe bar 22 by chains 26 and adjustable hooks 21. By connecting the hooks 2! in the proper links of the chains, and moving the levers down to the position shown, the bar '22 is drawn down tight, thereby locking the entire bank of gear housings I8 solidly.

Resilience may be introduced into the holddown feature either by providing all the bars l2 with rubber cushions 23 as described above, or by inserting a suitable spring (not shown) in each of the chains 26.

The bank of shafts I9 is similarly held down solidly by a hold-down bar 28 placed between the guides I0 and resting upon the top row of shafts I9. Said bar 28 is provided with shoes at each end which fit slidably into the channel guides I8 and hold the bar at the proper inclination, one of said shoes being shown at 29. Chain and eccentric pull-down devices, similar to those described above, are provided for the bars 28.

In stowing freight of the character described in railway cars or other vehicles having side doors, the banks at the ends of the vehicles will be stowed first, then the next banks, and so on until the doors are reached. When the vehicle is to be used for other kinds of freight, the transverse bars H, I2, I4, 2|, 22and 28, and the center supporting columns I6, can be either removed or stored at the ends of the vehicle where they occupy little space.
