22 Claims.

Our invention relates to improvements in convertible railway freight cars and particularly to box cars having side doors.

The present improvement contemplates a con vertible freight car construction in which standard practices in general construction and use prevail and in which a movable partition is employed to divide the car into compartments for the use of individual shippers of less than carload lots.

Somewhat similar structures are disclosed in Patent No. 2,009,894 of July 30, 1935 to Charles L. Madden, one of the present applicants, and Patent No. 2,009,895 of July 30, 1935 to Charles L. Madden and Arthur J. Hersey, the two present applicants. In each of said patented structures, a partition is movable into and out of operative position substantially in a vertical plane passing through the meeting lines of the opposed double doors. Patent No. 2,009,894 discloses doorways at the sides of the car located directly opposite each other, the partition being pivotally hung from overhead to swing into a horizontal position of disuse along the roof, said partition having wings, one at each side thereof, adapted to swing into and out of their respective doorways when the partition is disposed for use in a vertical position. Patent No. 2,009,895 discloses a car havin staggered doorways and a sliding partition which is guided into position of use so that the marginal portions at the sides thereof enter the doorways and traverse the car from door to door, said partition being guided out of its position of use so that said marginal portions thereof are brought within the inner confines of the car proper.

The present invention involves car construction having side doorways and a partition pivotally hung from overhead, diagonally of the car, and adapted to swing down into position of use, it being an object of our invention to provide a simple, durable and practical construction of such kind in which the partition is formed with a diagonally hinged corner section, whereby said partition. may be readily folded and swung upwardly into position of disuse in the upper portion of the car and readily lowered and unfolded to divide the car into individually accessible compartments.

An object of the invention is to provide a partition and operating means therefor, as above, whereby the folding and unfolding of the hinged corner section automatically attends the raising and lowering of the partition body.

ihe present invention further involves the common type of car construction, known as the automobile car, having staggered doorways fitted with outside double doors meeting midway of the door openings, it being our further object to provide partitioning means as above, in which the unfolded partition, in position of use, extends into the doorways and in which the folded partition clears the doorways and is accommodated between the inner walls of the car proper. The automobile car, advantageously lends itself to our present improved construction, due to the diagonal disposition of the partition axis which corresponds with the plane of the meeting lines of the double doors.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the drawings, Fig. 1 is a fragmentary elevational view of a convertible car construction embodying our invention, the structure of the car proper being partly broken away to reveal the partition and the operating means therefor; Fig. 2 is a vertical sectional View taken as on the line 2-2 of Fig. 3; Fig. 3 is a horizontal sectional view taken through structure of the car proper, as on the line 3--3 of Fig. 1, the partition supporting beams and the partition itself being shown in plan; Fig. 4 is an elevational perspective view taken from the side of structure opposite to that shown in Fig. 1, the partition being shown in the position assumed thereby, just after the raising thereof is begun or just before the lowering thereof into position of use is completed; Fig. 5 is a view similar to Fig. 4, the partition in this case being shown as swung up into the upper portion of the car into its overhead position of disuse; Fig. 6 is a sectional view taken as on the line 66 of Fig. Fig. 7 is a fragmentary olevational view of the partition showing in detail the hinged connection between the body of the partition and the folding corner section thereof; Fig. 8 is a detail sectional view taken as on the line 88 of Fig. 2; Fig. 9 is a detail sectional View taken as on the line 9-9 of Fig. 2, said view illustrating the partition construction and the manner in which the partition is hingedly hung from within the roof of the car structure; Fig. 10 is a detail sectional view taken as on the line Id -I0 of Fig. 9; Fig. 11 is a fragmentary elevational view in detail of the partition locking bolt at the lower left hand corner of the partition as seen in Fig. 2, said view including a sectional illustration of a portion of the car floor with which said bolt cooperates; Fig. 12 is a sectional view taken as on the line l2-IZ of Fig. 11; Fig.

13 is a perspective view in detail showing the free corner of the hinged partition section and the locking bolt thereon securing said section folded against the partition body, as seen in Fig. 5; Fig. 14 is an elevational View, partly broken away, illustrating the swiveling sheave over which the partition operating cable travels; Fig. 15 is a detail sectional view taken as on the line l5--l5 of Fig. 14; Fig. 16 is a sectional view taken as on the line l6---I6' of Fig. 6, said view showing in elevation one of the latching devices employed for releasably holding the partition in its overhead position of disuse, and Fig. 17 is another elevational view of said latching device, the same being taken at right angles to the View shown in Fig. 16.

Referring to the drawings, it will be seen that the car structure proper consists of an ordinary form of box car construction having a floor 20, side walls 2|, and a roof 22 supported by carlines 23. Doorways 24 at the sides of the car are relatively staggered and equally offset from the middle of the car longitudinally thereof, said doorways being provided with

double doors

25, 26 slidable along the outside of the car and which, when closed, meet midwidth of their respective doorways. The frames for the doorways 24 include side posts 21 to which the inner lining 28 and outer sheathing 29 of the walls 2| are secured. The door 25 of each pair of doors opens in the direction of the near end of the car and carries a reinforcing post 30, which, in the closed position of said door, is releasably anchored to the doorway frame in any suitable manner. The invention contemplates releasably securing the two doors of each pair individually in closed position and this may be accomplished in any suitable manner such, for example, as disclosed in said Patent No. 2,009,895.

A partition A is employed to divide the car into two compartments, each of which is accessible through the doorway at either side of the car. This partition in its entirety is generally rectangular in shape, the corners thereof being beveled. Said partition is hingedly supported at the top thereof and is swingable to occupy an overhead position of disuse horizontally in the upper portion of the car and to occupy a vertical position of use substantially in the plane of the meeting lines of the double doors at the sides of the car. Included in the partition A are a body 3| and a diagonally hinged corner section 32, the body 3| being in the form of a right trapezoid with the longer of the parallel sides at the top of the partition, the corner section 32 being in the form of a right triangle with the base at the bottom of said partition. In the construction of the partition body 3| a head rail 33 is employed, the same being I-shaped in cross section. A right angle stile 34, diagonal stile 35 and lower rail 36, constituting frame members of the partition body 3|, are all constructed from a piece of channel iron bent, as shown, with the legs of the channel iron extending inwardly, said

stiles

34, 35 being secured to the head rail 33, one channel of said rail, like the channels of said stiles being faced inwardly. Reinforcing ribs 31, I-shaped in cross section, extending longitudinally of the partition body 3| are received at their upper ends in the lower channel of the head rail 33 and at their lower ends in one or the other of the

frame stiles

34, 35. Spanning the spaces between the ribs 37 are sheet metal panel strips 38 of heavy gauge, the edges of which are received in the channels of the ribs 3! and secured, as by welding, to the webs of said ribs. The upper edges of said panel strips 38 are received in the downwardly facing channel of the head rail 33 and welded to the web thereof, the lower edges of said strips being likewise received in the chan nel and welded to the web of one or the other of the

frame stiles

34, 35. Spaced corrugations 39 formed transversely of the panels 38 reinforce them and by engagement with corresponding flanges of the ribs 31, at one face of the partition body 3|, hold the panels proper against the rib flanges at the other face of said body. The construction of the corner section 32 of the partition A is similar to that of the body 3| thereof, said section having frame members including a diagonal stile 40, matching with the diagonal stile 35 of the partition body 3|, a right angle stile 4| and a base rail 42, all of said members being formed from a length of channel iron, the flanges of which extend inwarlly of the frame. As in the partition body 3|, the corner section 32 is provided with reinforcing ribs 43 and panels 44. A piano hinge construction by means of which the corner section 32 is hinged to the body 3| of the partition A permits said section to fold out of the plane of the partition body only in one direction. This hinge construction, best seen in Figs. 7 and 8, comprises a number of paired

hinge members

45, 45, the member 45 of each pair being welded to the diagonal frame member 35 of the partition body 3| and the member 46 being welded to the diagonal frame member of the corner section 32. The hinge members 46 on the corner section 32 bear upon the hinge members on the partition body 3| and all of said

members

45, 46 swing on a hinge rod 41, the axis of which lies in the plane of one face of the partition body 3|. A batten strip 48 is employed to cover the space occupied by the

members

45, 46 between the stile 35 of the partition body 3| and the stile 46 of the corner section 32, said batten strip 48 being secured along one margin to said stile 40 of said corner seeltigi 32 at the face thereof opposite the hinge ro The construction by means of which the partition is hingedly hung from the top thereof consists of a pair of trunnions 49 issuing from the ends of the head rail 33 axially thereof, said trunnions being journalled in angle bearing plates 50 secured to angle beams 5| fastened to and extending along wall plates 52 at the upper portion of the car.

The partition A is swung upwardly from its position of use to its overhead position of disuse and again lowered to said first position by means of hoisting tackle now to be described, said tackle additionally serving automatically to fold the corner section 32 of the partition upon the body 3| thereof, as the partition is raised, and also serving to free said section to permit it to swing by gravity into the plane of the partition body 3| in the lowering of the partition. Said hoisting tackle includes a cable 53, one end of which is passed through a grommet 54 in the partition body 3| and fastened by means of an attaching clip 55 to the partition section 32 near its free corner. This cable 53 runs over

sheaves

56, 51 and 58 in the roof of the car and is attached to a winding drum or Windlass 59 mounted on one side of the car. Said drum or Windlass 53 is turned by worm gearing 53a which is driven by a chain wheel 5% fitted with an endless chain 590 for operating the same. Attention is called to the relative locations of the sheave 56, grommet 54, and cable attaching clip 55 by reason of which said elements come into line in superimposed relationship when the section 32 is folded upon the body 3| of the partition A and said partition swung up into its position of disuse (Fig. 6). With the partition in position of use (Fig. 2), the grommet 54 occupies a position, laterally of the car, to the right as compared with the position of said grommet in the elevated position of the partition. Accord- 'ingly, the sheave B is swiveled to conform with the changing angular relation of the cable 53 between said sheave 56 and the grommet 54 as the partition is raised and lowered. Details of this swiveling sheave 56 appear in Figs. 14 and 15, where it is seen that said sheave includes a tubular body 68 having spaced flanges 6| depending therefrom and between which a grooved wheel '82 is disposed, said wheel being journaled on a pin 63 supported at its ends by said flanges. Said tubular body 68 has reduced ends 84 which turn in bearings in the webs of

U-shaped brackets

65, 86, the legs of which are bolted to the facing sides of adjacent carlines- 23-. The cable 53 running over the grooved wheel 82, extends into and through the bore 81 of the body 60.

While the drum 59 is" worm driven, we prefer to secure the partition A in its elevated position independently of the cable 53 and thus relieve it of the load while the partition is not in use. Accordingly, we provide a pair of latching devices b in the roof of the car which catch a corner of the partition body 3| in the elevated position of the partition and alone hold the partition elevated. These latching devices are identical, one thereof being illustrated in detail in Figs. 16 and 17. The device shown includes a mounting bracket 58 depending from a carline 23. This bracket has a vertically disposed reach 69 which serves to brace the partition against lateral movement in one direction. At the lower end of the reach 69 is an outwardly inclined cam portion 18 adapted to engage and guide the partition body 3| into line with the inner face of the reach 69. Pivoted on a pin 1| carried by the bracket 68 is a depending dog 12 for catching and holding the upwardly swung partition. A spring 13, coiled about a hub portion 14 on said dog and reacting against the bracket 68 and a lever extending upwardly from said hub, yieldingly holds the dog 12 in partition-holding position, a limit stop 18 on said dog abutting the cam portion 19 of the bracket 58 in such position of said dog. The two latching devices I), are oppositely diagonally related with respect to the car, one being disposed to catch the lower rail 39 of the partition body 3| and the other the stile 34 of said body (Fig. 6). The reaches 69 of the brackets 68 together stay the elevated partition against lateral movement in both directions, thereby relieving the structure from strains which otherwise would arise from such movement of the partition. The self-latching dogs 12 are unlatched manually by means of latch cord branches H, 18 running over guide pulleys I9, 88 and connecting at 8| with a main drop cord 82, in turn, running over a guide pulley 83 and hanging at the side of the car within reach of the Windlass 59.

In the operative position of the partition A, the body 3| thereof is releasably locked to the floor 29 of the car to secure the partition from swinging on the supporting trunnions 49 and the corner section 32 is likewise locked to the car floor to contribute to this anti-swinging movement of the partition and to secure said partition section 32 against swinging on the partition body 3| out of the plane thereof. To this end, the body 3| of the partition and the section 32 are supplied with floor locks c, the former having one at each of its lower corners and the hinged section 32 having one at its free corner. The construction of one of these locks, all being identical, is illustrated in detail in Figs. 11 and 12. This lock includes a bolt 84, round in cross section, slidably' and. rockably mounted in a tubular guide 85, set into a slot in a partition panel 38 and welded to the panel. The lower portion of the bolt 84 is received in an opening formed in the web of the bottom rail 33 and in an opening in a boss 86 welded to the lower face of said web, the lower extremity of said bolt being adapted to enter a socket plate 81 recessed in the car floor 28. Issuing from the upper portion of the bolt 84 is a latch lever 88 which is free: to swing through 180 with the turning of the bolt 84, the upper portion of the tubular guide at one side of the plane of the panel 38 being cut away to accommodate such movement of said lever 88. Upwardly opening

keeper slots

89, 98 in opposite sides of the tubular guide 85 receive the lever 88 edgewise in the corresponding angular relations of the bolt 84, the slot 89 being relatively shallow to retain the bolt 84 elevated suiii-ciently to clear the car floor 28 when the partition A is lowered into position of use. Slot 9!! is deeper than slot 89 to allow the bolt 84 to be thrust down far enough to project the lower extremity of the bolt into the bolt receiving socket of the socket plate 81. At the top of the guide 85 is an upper limit stop 9| for precludingthe endwise removal of the bolt 89 from said guide. Means are provided to prevent the bolt 84 from becoming unlatched from the floor plate 81 as by working itself upwardly or as by being lifted by unauthorized persons. The slot 98 is enlarged at its lower end to form a shoulder 92 beneath which the latch lever 88 may be engaged upon the swinging of said lever out of the plane of the slot proper. With said lever 88 caught under said shoulder 92, the bolt 84 is effectively held against upward movement in the guide 85. Officially, to keep the lever 88 beneath said shoulder 92, a car seal of usual construction is used, the wire or ribbon 93 of the seal beinglooped through an opening 94 in said lever 88 and through an opening 95 in a bracket 95 welded to the panel 38, the bracket opening 95 being so disposed that the seal wire 93 holds the latch lever 88 beneath the retaining shoulder 92 of the guide 85.

In permitting the latch dogs 12 in the roof of the car to support the free end of the partition body 3|, the hoisting cable 53 is slackened after the engagement of said dogs with said body. This, without provision to the contrary, would allow the folded corner section 32 of the partition A to unfold, by gravity, relative to the partition body 3|. To secure said corner section 32 folded against the body 3|, we employ the floor lock 0 of the corner section 32 (Fig. 13), the: bolt 84 in such case being projected into a bolt receiving opening 91 in a latching flap 98 pivotally mounted on the partition body 3|. This latching flap 98 consistsof a plate having trunnions 99 journaled in eyes |88 issuing from an anchoring plate |8| welded to a panel 38 of the partition bOldY 3|. In thus using this floor lock 0 to retain the corner section 32 folded against the partition body, the retaining shoulder 92, overreaching the latch lever- 88, keeps the bolt 84 from creeping out of latching. relationship, gravity, in this case, holding the lever 88 against swinging to clear said shoulder 92. The pivoting of the latching flap 98 permits it to hang in an unobstructing position flush against the face of the partition body 3| (Fig. 4) in the upright position of the partition.

The partition A is safely' supported and braced inan. overheadposition whennot. in' use, the eniii tire interior of the car being available for all usual purposes. In position of use, the partition divides the car in the plane of the meeting lines of

double doors

25, 26 at the opposite sides of the car, each compartment being individually accessible from the doorway at either side of the car, the compartment through which the cable 53 extends being unobstructed by said cable simply by hooking the slackened cable over the hook I02 (Fig. 1) at the top of the partition body 3|, said body having folding steps I03 thereon for the convenience of the user in reaching said hook.

In bringing the partition A from its position of disuse to position of use, the drum 58 is first turned to tighten the cable and lift the free end of the partition body 3| from the latch dogs I2. These dogs I2 are then temporarily retracted by pulling on the drop cord 82 and the drum 59 is then turned to pay out the cable 53 and permit the end of the partition body 3| to swing down beneath the level of said dogs 12, whereupon the drop-cord 82 may be released. As the paying out of the cable 53 continues, the floor bolt 84 on the hinged partition section 32 is released from the latching flap 98 on the partition body 3| so that said section 32 will be free to unfold by gravity from the partition body when the partition arrives at the final stage of its lowering movement. In this stage, the corner section 3| begins to turn on its diagonal hinge rod 4-! and continuing to turn arrives in the plane of the partition body 3| as it proceeds to swing into vertical position.

While the side marginal portion of the partition section 32 enters its respective doorway, the opposite margin of the partition body 3| enters its respective doorway, thus partitioning the car beyond the inner confines of the car lining 28 and from door to door through the doorway recesses. This effectually isolates the two compartments from each other. In this connection, it is to be noted that the marginal portions of the partition, which enter the doorways 24, are foreshortened at the top by the bevelling of the 5 upper corners of the partition, such construction allowing clearance for the partition, where it is reduced in width in order to be accommodated between the inner walls of the car. In the depending position of the partition A, the bolts 84 of the floor locks c are lowered into their socket plates 81 in the car floor 20 and, if desired, sealed in such partition-locking positions, as by the seals 93.

To return the partition A into position of disuse, the floor bolts 84 are withdrawn from the floor sockets 81 and latched in retracted position. The cable 53, released from the hook I02, is then wound in on the Windlass 59. At the start and due to the right angle bend of the cable 53 at the grommet 54, the whole partition is swung slightly out of the vertical (Fig. 4). This occurring, the corner section 32 of the partition, by gravity, begins to fold on the diagonal hinge rod 41 toward the partition body 3|. Concurrently with this folding movement of the corner section 32 and with the diminishing friction between the cable 53 and grommet 54, the bend in the cable decreasing, the partition body 3| settles back toward its initial vertical position, where it is met by the folding corner section 32 coming against it. Thereupon, the two parts of the partition are elevated together, the bolt 84 of the floor lock c on the corner section 32 being caught in the latching flap 88 on the partition body 3| as the partition continues to be swung upwardly. Reaching the latching devices b at the roof of the car, the partition body 3|, if out of its proper lateral relationship, engages the cam portion I0 of one or the other of said devices and is thereby appropriately shifted to take position between the stay reaches 69 of the celling brackets 68. While the partition body 3! is within the range of the cams 10 of the brackets 68, cam edges I04 of the latch dogs 12 (Fig. 16) are engaged by said body 3| and the dogs I2 are thereby sprung back until the body 3| passes shoulders I05 on said dogs, whereupon the dogs snap into holding positions with said shoulders I05 beneath the rail 36 and stile 34 of said body 3|, The cable 53 is then slackened, permitting the partition A to settle onto the latch dogs I2.

Due to the initial folding of the corner section 32 against the partition body 3|, said sec- .tion is withdrawn from its respective doorway 24 into a position to clear the door frame and the corresponding wall lining 28 of the car. At the other side of the partition, the marginal portion of the partition body 3| swings out of its doorway 24 and clear of the door frame and corresponding wall lining 28, due to the biased manner in which the partition is hung. In this connection, attention is invited to Figs. 3 and 6, the former showing the partition in position of use with the opposite marginal portions thereof projecting beyond the planes of the wall linings of the car and into the doorways thereof, while Fig. 6 shows the partition swung into its overhead position of disuse with the folded corner section 32 and the partition body 3| accommodated between the wall linings 28.
