United States Patent Ofilice 3,018,741 LADING SEPARATING MEANS Russell M. Loomis, Palos Heights, Adolph G. Kuellmar,

Chicago, and John S. Lundvall, Park Ridge, 111., assignors to Union Asbestos & Rubber Company, Chicago, Ill., a corporation of Illinois Filed Aug. 26, 1959, Ser. No. 836,288 Claims. (Cl. 105376) This invention relates to load separating means and more particularly to load dividing doors supported in a railway car, or similar vehicle, and movable to different positions therein to separate the lading space into a plurality of separate compartments. For properly separating lading in railway cars and similar vehicles, the separating doors must be very strong and rugged to withstand the loads and impacts imposed thereon in service which means that they are relatively heavy. They must also be so supported in the lading space that they can be moved relatively easily from place to place therein and must be capable of being securely latched in different positions. These several requirements make it difficult to produce a completely satisfactory lading separating means and those heretofore proposed have not been entirely satisfactory in all respects.

It is accordingly one of the objects of the present invention to provide lading separating means which satisfies all of the commercial requirements in being easy to move to different adjustable positions, securely latched in the different positions and extremely strong without requiring excessively large and heavy supporting and latching means.

Another object is to provide lading separating means in which the lading separating doors are pivotally supported on generally horizontal pivoted arms near the roof of the car for pivotal movement on the arms between open and closed positions and for bodily movement through swinging of the arms to stored positions adjacent a side wall of the lading space.

Preferably the arms are supported on beams movable longitudinally of the car on tracks so that the doors are bodily movable to any desired position lengthwise of the car.

A further object is to provide lading separating means in which the weight of the door is removed from the supporting means when the door is latched in either its open or closed position.

According to a feature of the invention, the door is latched by latching means, including vertically movable latch pins projecting from the bottom of the door, and which engage the floor of the car to lift'the weight of the door from the supporting means in' their latched positions.

The above and other objects and features of the invention will be more readily apparent from the following description when read in connection with the accompanying drawings, in which:

FIGURE 1 is a transverse section through a railway car equipped with lading separating means embodying the invention;

FIGURE 2 is a partial enlarged section of the upper part of the car;

FIGURE 3 is a partial enlarged section of the lower part of the car;

FIGURE 4 is a partial plan view illustrating movements of the supporting arm and the door;

FIGURE 5 is a partial longitudinal section illustrating the latch operating means; and

FIGURE 6 is a partial view similar to FIGURE 4 illustrating a modified construction.

While the lading separating means of the invention is applicable to any type of lading space, it is particularly 3,018,?41 Patented Jan. 30, 1962 illustrated as applied to a railway car having side walls, indicated generally at 10, a roof, indicated generally at 11, and a floor, indicated at 12. The floor may be provided with the usual lading receiving racks 13 which are spaced slightly above the actual floor itself to receive the lading. As shown, the roof of the car is supported by transverse beams 14 which serve also to carry the supporting means for the lading separating doors, as described hereinafter.

The lading space within the car is adapted to be separated by doors 15 which are movable from place to place in the car and which can be latched in any one of a plurality of closed or stored positions in the car. While the doors may be of any desired construction, they are preferably hollow, as shown in FIGURE 5, with face plates on the opposite surfaces thereof to provide a smooth surface for engagement with the lading. It will be appreciated, of course, that the doors could, if desired, be perforated or could be of any other preferred different type of construction.

To support the doors for movement to different positions in the car, tracks 16 are secured in the upper part of the car adjacent to the side walls thereof. As best seen in FIGURE 2, each of the tracks is formed of an elongated strip of sheet metal bent to a generally C-shape and providing a straight upwardly extending flange adjacent to the interior of the car to serve as a track. The track structures are secured to the roof of the car to be supported by the beams 14.

A double track structure, indicated generally at 17, extends along the center line of the car and is provided with two generally C-shaped track members 18 having upwardly extending flanges thereon to form tracks facing respectively toward the side walls of the car. These track members are secured to the roof of the car and are connected by a latch plate 19 at their lower edges, whose purpose will appear more fully hereinafter.

A transverse beam 21 is mounted on each pair of

track members

16 and 18 for movement lengthwise of the car on the track members. As shown, each beam 21 is of L-section and carries rollers 22 at each of its ends which ride on the upwardly extending flanges of the

track members

16 and 18. As best seen in FIGURE 5, each end of the beam is provided with an arm 23 extending along the track and carrying a roller 24 at its free end fitting between the upturned bottom flange on the track and the upper surface thereof to limit twisting or tilting of the beam.

Each of the beams has pivoted thereto a generally horizontal arm 25 which is pivoted to the beam on a vertical pivot 26 at one end of the arm. Each of the pivots 26 is spaced from the adjacent side wall of the car, but is closer to the side wall than to the center of the distance between the

tracks

16 and 18, as shown. One of the doors 15 is pivoted centrally of its width and at its upper edge to the free end of each of the arms 25 on a vertical pivot 27. Preferably the pivots 27 or the pivots 26, or both, have a small degree of free movement vertically and will support the door so that its lower edge is spaced just above the floor racks 13 while permitting the door to be elevated a slight amount from this position. Swing ing of each of the doors relative to the beam from which it is supported is limited in one direction by stop means shown as comprising a plate 28 fixed to and projecting slightly below the beam and a stop finger 29 secured to the upper edge of the door at one side thereof to engage the plate 28 when the door is in its closed position. It has been found that this construction greatly simplifies proper aligning of the doors in their closed positions and also makes it easier to move the doors and beams lengthwise of the car when the doors are being adjusted.

The doors are adapted to be held in any one of a plurality of positions in the car by cooperating latching means on the car and the doors. The latch plate 19 forms a part of such latching means and for this purpose is provided with two sets of spaced openings 31 adjacent its edges. Similar plates 32 are formed as a part of the track structures 16 and are formed with spaced latching openings therein. At the floor of the car, as best seen in FIGURE 3, channel-shaped latching strips 33 are secured with their webs upward to be flush with the upper surfaces of the floor racks 13 and provided with series of spaced latching openings 34 therein.

Each of the doors carries four latching pins with two latching pins 35 at its upper edge near its opposite sides and two latching pins 36 at its lower edge near its sides. The

latching pins

35 and 36 may be moved between their released and latched positions by a mechanism, as illustrated in FIGURE 5. As there shown, each door is provided with a shaft 37 extending across its width and which is adapted to be turned by a handle 38. Preferably, the door is formed with a recess in one face in which the handle 38 may be received when the latch pins are extended to their latching position so that the face of the door is flush. Each shaft 37 carries a pair of cross heads 39 at its opposite ends and the cross heads 39 are directly connected through links 41 to the lower latch pins 36, as shown in FIGURE 5. Links 42 connect the cross heads to the upper pins 35 through lost motion connections 43 and springs 44 are provided urging the upper latch pins upwardly to their latching positions.

According to one feature of the invention, the lower latch pins 36 are provided with reduced tips 45 of a size to enter freely into the latching openings 34 in the latch strips 33 and with enlarged body portions joined to the reduced tips through shoulders 46 which of larger size than the latching openings 34. The linkage is so proportioned that when the handle 38 is moved upward from the release position shown in dot-dash lines in FIGURE to the full line latching position, the lower latch pins 36 will move down to the point where the shoulders 46 engage the upper surfaces of the latch strips 33 which define the floor of the car before the handle reaches its full upper position. The small amount of remaining movement of the handle to move it to its full latch position within the recess in the door will project the latch pins 36 further downward from the door, causing the latch pins 36 to raise the door slightly and to remove the weight thereof from the supporting means, including the arm 25, pivot 26 and beam 21. These supporting parts may therefore be made only heavy enough to support the door for movement from one position to another in the car without being required to absorb any of the shocks or loads imposed upon the door during operation of the car.

In using the lading separating means of the invention, the doors 15 may be swung to the stored position shown at the right in FIGURES 1 and 2 for loading the car. In this position, the arms 25 are swung around so that their free ends lie closely adjacent to the side wall of the car, as particularly illustrated in FIGURE 4, and the doors are turned about the pivots 27 to a position adjacent and parallel to the side walls of the car. The doors may be latched in this position, if desired, and should be so latched if the car is to be moved with the doors in the stored position. This can be accomplished by Swinging the handle 38 upward into the recess in the door thereby causing the latch pins 35 and 36 to project into the latch openings in the

strips

16 and 33 to hold the doors securely in the stored position. It will be noted that the weight of the doors when latched is picked up by the lower latch pins 33 so that the doors are supported solely by the latch strips and all strain is removed from the arms 25, the

pivots

26 and 27, the beams 21 and the tracks.

When the car is loaded and the doors are to be moved to their closed positions, the latches may be released by swinging the handle 38 down to the dot-dash line position of FIGURE 5 and the arms 25 may be swung out to the position shown at the left of FIGURE 1 and in dot-dash lines in FIGURE 4. In this position, the pivots 27 lie centrally between the

tracks

16 and 18 and the doors can be swung to their closed positions, as shown. The doors can also be moved lengthwise of the car by moving the beams 21 along the tracks to the desired position in the car and can be latched in this position by raising the handles 38 into the recesses in the doors. At this time also the Weight of the doors will be picked up by lower latch pins 36 so that all strain is removed from the tracks, beams, arms 25 and pivots 26 and 27. This enables these parts to be made relatively light, merely sufficient to support the weight of the doors without being required to absorb any of the shocks incident to travel of the loaded vehicle. It will thus be seen that the doors are supported with complete flexibility for movement to closed or stored positions in any part of the car. Due to the fact that the arms 25 are pivoted they will move freely and easily so that the doors can be swung with a minimum of effort from one position to another and can be securely latched in any position to which they are moved.

FIGURE 6 illustrates a modified construction wherein parts corresponding to like parts in FIGURES l to 5 are indicated by the same numerals, plus 100. By comparison of FIGURE 6 with FIGURE 4, it wil be observed that the principal difference is that the arm 125 is made slightly longer than the arm 25 of FIGURE 4 so that it never moves into a position completely parallel with the beam 121. Thus, with the door in its stored position adjacent to the side wall of the car, the arm lies at a slight angle to the beam 121 rather than being parallel to it. Similarly, in the closed position of the door, as shown in dotted lines, the arm 125 is at a slight angle to the beam 121. With this construction, slightly more flexibility in the degree of movement of the door is provided so that the parts need not be made quite as accurately as with the construction of FIGURES 1 to 5. Furthemore, this construction is better able to accommodate slight variations in the width of a car while still enabling the doors to be moved closely adjacent to the car side walls for storage or to the desired position transversely of the car for functioning as lading separators. Otherwise, the construction is the same as FIG- URES l to 4 and functions in the same manner.

While two embodiments of the invention have been shown and described herein, it will be understood that they are illustrative only and not to be taken as a definition of the scope of the invention, reference being had for this purpose to the appended claims.
