Claims. (Cl. 10S-376) This invention relates to railway cars and particularly to an improved lading barrier or bulkhead structure for freight cars and similar lading carrying vehicles. While the device is shown and described as particularly suitable for cars used in shipping or transporting granular or powdered lading such as china clay, cement, grain and the like, it is also adapted for use with other types of lading or as a partition dividing the car into compartments.

Certain objections to various types of lading retaining bulkheads now in use include lack of means for positively maintaining the bulkhead in lading retaining position, especially in transit, complicated or laborious operation, complicated structure or mechanism, etc. In the shipment of lading such as china clay and the like, a temporary bulkhead is sometimes erected which has to be torn down before unloading the car, involving possible damage to the car in addition to cost of labor and materials.

It is an object of the present invention to provide a lading barrier or bulkhead structure of relatively simple construction and easy and quick to operate.

A further object is to provide such a structure having a plurality of vertically slidable sections and means for operating the same, which means shall not include counterweights or other balance means.

Another object of the invention is the provision of a multi-section structure of the type described in which the individual bulkhead sections are positively held down in operative position to insure the lading being properly retained in transit.

Still another object of the invention is to provide a structure as above described in which raising of the lowermost bulkhead section by shiftable hoist or similar means raises all sections together in a single operation to a sideby-side elevated inoperative position. As the sections of the bulkhead of the invention are arranged in stepped relation to one another in the down or operable position, the raising of the sections will be accomplished with less friction betweenthe lading and the lading retaining surfaces of the individual bulkhead sections than would occur with the raising of a single section bulkhead, and access to the lading at various heights above the door, corresponding to the raised heights of each section, will be available.

`A further object of the invention is to provide a structure as above described in which the lading retaining surfaces of the bulkhead sections are sloped downwardly and outwardly to reduce friction of the lading thereagainst while being raised, thus easing operation of the bulkhead.

These and other objects of the invention will be apparent to those skilled in the art from a study of the following description taken with the accompanying drawings in which:

Fig. 1 is a partial longitudinal vertical sectional view through a railway freight car showing the lading barrier or bulkhead structure as used at opposite sides of the side doorway, the structure on the left being shown in the down position and that on the right in partially raised position;

Fig. 2 is a fragmentary transverse sectional view through the car showing the structure in the down position across the car with a small portion thereof broken away to better disclose the same;

Fig. 3 is a cross sectional view taken on the line 3--3 of Fig. 2;

Fig. 4 is a cross sectional view taken on the line 4 4 of Fig. 3;

Fig. 5 is a side elevation view showing in the down position a modied form of the structure in which the lading retaining surfaces of the bulkhead sections are sloped downwardly and outwardly for the purpose hereinbefore mentioned;`

Fig. 6 is a schematic view showing the modified structure in partially raised position, and

Fig. 7 is a view similar to Fig. 6 showing the modified structure in the fully raised position.

Referring now more in detail to the drawings, the lading barrier or bulkhead structure generally designated A is shown in Fig. l as installed in a box or similar freight car B having a roof C and floor D. The bulkhead structure extends transversely of the car and is shown as located at opposite sides of side doorways E, only one of which is shown, although but one structure may be used and in any other desired location in the car. The side door posts F of the car, as more clearly shown in Figs. 3, 4, are channels each having a web 8 and inwardlydirected anges 1G. Angles 12, 13 secured by rivets 14 or other suitable means to the channel web 8 divide the channels into a plurality of vertical guideways 16, 18, 20. Guideway 16 is defined by the channel web 8, one flange 10 and leg 22 of angle 12, while guideway 18 is defined byangle legs 22 and 23 as well as by the channel web and the attaching liange of angle 12. In a like manner, guideway 20 is defined by angle leg 23 and channel flange 10 as well as by the channel web and the attaching flange of angle 13.

A multi-section bulkhead made up of lower, middle and upper bulkhead sections 24, 26, 28, respectively, eX- tends between and is slidably arranged, respectively, in pairs of opposite guideways 16, 18, 20. The bulkhead may comprise any desired number of sections with a corresponding number of guideways, each section being formed in the instance shown by spaced sheet metal panels 30 connected together by top and bottom channel members .32 and end channel members 34 positioned in the respective guideway. The bulkhead sections are reinforced by intermediate Z bars 36 and provided with pairs of top and bottom anti-friction rollers 38 extending from the ends and with their axes extending transversely of the section and also provided with similar rollers 40 extending from the sides of the sections with their axes at right angles to the rollers 38. The rollers 38 extending from the ends are carried between spacers 42 by pins 44 journalled in the flanges of side channel members 34 and secured by cotter pins 46. The rollers 40 extending from the sides are` carried between a spacer 48 and plate 50A Welded to the channel member flanges by pins 52 journalled in the plate 50 and web of the channel members 34 and secured by cotter pins S4. As will be understood, the rollers 38 project beyond the ends while rollers 40 project beyond thesides of the bulkhead sections for riding in their respective guideways during raising and lowering of the bulkhead sections, with the lower section 24 thereof in guideways 16, the middle section 26 in guideways 18 and the upper section 28 in guideways 20.

The bulkhead sections are supported in stepped relation to each other when in the down position with the lowermost section 24 supported on Hoor D of car B and with the middle and upper sections 26 and 2S supported by angles 56 welded to angles 12 and 13 respectively, angles l565 thus being immovably positioned in and projecting into V guideways 18, 20. It may be noted here that the guideway angles 12 extend the full length of channel posts F since they form part of the guideway for the lower bulkhead section', while angles 13 extend approximately down only three-fourths ofthe length to form part of the guideways for bothv middle and upper bulkhead sections. Welded to the top of each bulkhead section adjacent the ends are one or more laterally extending members in the form of inverted T bars 58 located in staggered relation. The projections on the middle and upper sections have laterally outwardly projecting portions overlying or extending in overlapping relation' to the adjacent lower sectionand are engageable by the top of the next lower section duringraising of the sections. For example when thelowerrnost section 24 is raisedits top will engage the outwardly projecting, overlying portion of the bar 58 On the middlesection 26 and the two sections then move together until the top of 26 engages the bar S8 of section 28 after which all three sections move in unison tov a position adjacent the car roof C. The bars 58 of all sections except the topmost have laterally inwardly projecting portions' overlapping horizontally the angle bars 60 to be described. Abutment means in the form of angle bars 60 are welded to the lower edge portion of the middle and upper bulkhead sections 26, 28. These angle bar abutments extend laterally outwardly from their respective sections and are engaged by the adjacent projections 58 on the overlapping top edges of the lowermost and middle bulkhead sections respectively, whereby the middle and the upper section are positively held down against their respective supports S6 by the next lower section when the bulkhead is in the down position. The lowermost bulkhead section 24 is releasably locked in down position by a key pin 62 extending through key slots in guideway channel iiange 10, spaced section panels 30 and leg 22 of guideway angle 12 thereby locking all sections. The bulkhead sections are thus firmly secured in lading retaining position, which is important especially when the car is in transit and the sections subjected to jolting and jarring forces tending to separate them with consequent undesirable leakage of lading.

Extending between and secured to the upper ends of channel posts F are transversev support beams 64 connected intermediate their ends by a longitudinally extending rail member 66. A shiftable hoist 68 carried by rollers 70 riding on the rail member 66 is movable above the side doorways E between opposite bulkheads.y The hoist 68 is provided with a lift chain 72 having a hook 74 for connection to bail or other suitable means 76 welded centrally to the top of the lowermost bulkhead section 24 and is operated by pull cable 78. The hoist may thus be selectively connected to the lowermost section of either bulkhead to raise the same, the top of the sections succes-n sively engaging the projections on top of the next upper section whereby all sections are finally raised together in a single operation and releasably locked in side-by-side elevated position by insertion of key pin 62 in an upper key slot 80 similar to the lower key slot previously described.

T he modified form of the invention shown in Figs. 5, 6, 7 is the same as previously described except for thezsloping lading retaining surfaces of the bulkhead sections indicated at 82. It will be seen that these surfaces have been sloped downwardly and outwardly in a direction toward the car floor, thus reducing friction of the lading L thereagainst while being raised and easing operation of the bulkhead.

The invention may be modied in various respects as will occur to those skilled in the art and the exclusive use of all modifications that come within the scope of the appended claims is contemplated.
