Figure 2 is a vertical sectional vieu1 ofthe invention talren substantially on the line 2 2 of Figure 1, and showing the mountings on the car for supporting the doors, parte of the construction being broken. And Figure 3 is a vertical sectional view corresponding to line 3-3 of Figure 1, and showing upper and vlower parts of the door frame, portions of the view being broken avvay.

Referring to the draWinUs, 10 and 11 indicate portions of the lside Wall; of a box car, and 12 and 13 denote vertically extending door posts at opposite sides of the door opening in the side Wall of the car, each of the posts 12 and 13 beinguprovided With an angular metallic cover-plate indicated at 14 and 15, one end of each of the free ends 16 and 17 of the plates 14 and 15 providing means adapted to co-operate with portions of the door structure hereinafterV described. The upper portion of the door frame is defined by a Z-shaped side plate indicated at 18, the depending flange of which has mounted thereon a Z-shaped member 18a having a depending flange 185. The threshold of door frame is indicated at 19, and a track 19a is provided mounted on brackets secured to the side sill of the car. Y

In the arrangement shown, tWo sliding outside. doors are employed, one ofV Which may be termed the auxiliary door and designated A, and the other a somewhat wider door Which may be termed the main door and designated by the reference character B. The-auxiliarydoor A is composed of sheet metal throughout and preferably includes a plurality of connected panels arf ranged in rectangular form, the forward and rear edges of the rectangular formation being provided with vertically extending corrugations 20 and 21 which merge at the top and bottom portions ofL the rectangular formation with horizontally disposed corrugations 22 and 23, the rectangular formation outwardly of the corrugations 20-21 being kprovided With marginal portions v2li and` 25, While at the top and bottom of the door marginal sections 26 and 27 are provided. At the top of the door the corrugation 23 is spanned by a reinforcing strip 28 which is riveted to the main body portion of the door as indicated at 29 and 30. On the outer surface of the marginal section 26 of the main bodyportion of the door along the top edge thereof, there is provided an angle bar31 having one flange secured to said marginal section by the rivets indicated at 30, While the other flange of the bar 31 is horizontally disposed and `is adapted to cooperate with the depending liange of the Z member 18a to maintain the door in proper position during its sliding movements. At

the bottom of the door the corrugation 22 is spanned by reinforcing strip 32, said strip being fastened to the main body portion of the door by rivets indicated at 33 and 34. Secured to the outer side of the marginal section 27 at the lower edge of the door, are roller housings, `indicated at 35 carrying rollers 36 which run upon the track 19a. At the rear of the door the corrugation 20 is spanned by reinforcing strip 37 secured to the main body portion of the door by rivets 38, the strip 37 at the extreme marginal edge of the door being provided with an angular extension 39 adapted to cooperate with the extension 16 on the plate 14 to provide a weather andY spark seal at the rear end of the door when the same is in closed position. The corrugation 21 at the forward edge of the door is also spanned by a reinforcing strip 40, said strip having its opposite marginal edges secured to the main body portion of the doorby rivets 41 and 42. To the outer surface of the marginal section 25 is secured the movable door post 43. The post 43 comprises a 'relatively heavy metallic member including a web 44 extending substantially perpendicular with respect to the main plane of the door, and at each end of the web 44 the member 43 is provided with angularly disposed head portions 45 and 46, the portion 45 providing iianges 46L and 47, while the head portion 46 provides flanges 48 and 49. The flange 48 of the head 46 of the member 43 is disposed with its inner surface fiat against the marginal surface of the door A and the flange 48 is rigidly secured to the marginal section by the rivets 42. The web 44 of the member 43 is of such length as to project inwardly-of the main plane of the door A a considerable distance so as to dispose the head 45 of the member 43 somewhat inwardly of the plane defined by the inner face of the door post'- 12. EX- tending diagonally lfrom the inner surface of the door A toward the web 44 of the member 43 is a reinforcing element 50. Said element is secured to the door A by the rivets 41, and to the web 44 by the rivets indicated at 51. inwardly beyond t-he connecting rivets 51 the element 50 is provided with an angular flange 52 spaced from and disposed substantially in parallel relation with the flange 46fl of the head 45 o-f the member 43, the flanges 52 and 46;L and the web 44 defining a groove 53 adaptedfor the detachable reception o f thel ends of the boards 54, the opposite ends of the boards 54, when the door A is in closed position, being nailed to the post 12 as indicated at 55. Secured to the surface of the web 44 opposite to the face to which the element 50 is secured is a member 56 channel-shaped in cross section, the web of said member being secured to the web 44 of the post 43 by means of the rivets 51 which secure the element 50 in position, and by the rivets 57 which extend through the web of the channel member and the web of the post 43. The flangeA 57L of the member 56 is disposed in spaced parallel relation with the flange 47 of the member 43 to provide a groove 58 for the reception of the ends of the boards 59, the opposite ends of said boards being adapted to be nailed to the post 13 as indicated at 60. The other flange 61 of the member 56 is disposed in spaced relation with reference to the flange 49 of the head 46 of the member 43 and provides a groove 621 for the reception of the forward edge of the main door B. The main door B is also composed throughout of metal, and except for its greater width, and the omission of the door post, is practically identical in construction with the auxiliary door A and similar reference characters will be utilized to designate like parts of both.

In the use of doors of this character, means must be provided for locking the auxiliary door A in closed position. In eecting this purpose, a gravity actuated latch 62 is provided. Said latch is pivotally mounted upon a bracket 63 secured to the web of the Z-shaped member 18, by means of a pivot pin 64, to swing in a plane parallel to the plane of movement of the door A when slid back and forth across the door opening. The end 65 of the latch 62 is of greater length than the end 66 of said latch so that the end 65, which is disposed in a direction toward the door A, is normally urged, through the influence of gravity, in a downward direction, the upper edge of said latch being bevelled as indicated at 67 to permit the end 65 to be moved in an upward direction, while the extremity 68 of the end 66 of the latch bears against the undersurface of the web of the member 18 to limit downward movement of the end 65 of the latch. The end 65 of the latch is provided with a shoulder 69 adapted to engage behind the top end of the web 44 of the door post 43 when the door A is moved in a closing direction, the end 65 of the latch being bevelled as indicated at 70 to permit the latch to ride over the top of the web 44 of the post 43 during the time that the door A is being closed. The end 65 of the latch 62 .is also provided with a shoulder 690 adapted to engage the top end of the web 44 in certain positions of the parts. Reciprocably mounted upon the inner face of the web 44 is a locking bar or bolt 71, said bar being provided with slots 72 adapter to receive rivets 73 which extend through the web 44 of the member 43, and the web of the member 56, whereby the bar 71 may be reciprocated in a vertical direction, the lower end 74 of which under the influence of gravity normally projects below the bottom edge of the door post and is adapted to be disposed in a recess 75, corresponding in position to the shoulder 69, formed in a keeper casting 76. Said keeper casting is also provided with a recess 750, correspond ing in position with the shoulder 690, adapted for the reception ofthe lower end of the bar 71 when the parts are in certain positions. The casting 76 is mounted upon the threshold 19 of the door and is provided with inclined surfaces 77 and V78, the surface 77 providing cam means to permit the lower end 74 of the bar to ride thereover into position to enter the recess 75 when the door is being moved to closed position. The upper end of the bar 71 is provided with a turned port-ion 79 adapted to engage the lower surface of the end of the latch 62 so that upward reciprocation of the bar 71 will move the end 65 of the latch so that the Shoulder 69 is clear of the web 44, the upward movement of the bar 71 also serving to retract the lower end 74 of the bar from the recess 75 in the keeper casting. The reciprocation of the bar 7l may be effected through the medium of a handle 8O which projects outwardly through a slot 81 in the diagonal member 50, movement of said handle in an upward direction serving to lift the bar 71.

When it is desired to use the car for the transportation of large objects, such as automobiles, furniture, and the like, the boards 54 and 59 of course are dispensed with. During such use the auxiliary doorvA when moved in a closing direction automatically brings into operation the locking bar 71 and the latch 62, the lower end of the bar dropping into the recess 75 in the casting, and the shoulder 69 of the latch dropping over the upper end of the web 44 of the post 43, thereby securing the auxiliary door in its closed position, the post member 43 serving as an abutment and seal for the door B when the latter is closed, the forward edge of the door B being accommodated in the groove provided by the langes 61 and 49 of the channel member 56 and head 46 of the post 43. If it is desired to move and lock the door A a slightly greater distance forwardly as is sometimes necessary on account of distortion ofthe car body andother parts, the lowerend of the bar 71 may be retracted and engaged with the recess 750 which brings the shoulder 690 of the latch 62 into position to engage the top end of the web 44. In order to open the doors, the main door B is first slid back in the usual manner, after which the handle may be grasped by the operator and lifted, which retracts the lower end of the bar 74 from the recess 75 or recess 750 as the case may be to free the lower end of the door post, and by reason of the simultaneous upward movement of the angular portion 79 of the bar, the latch 62 is lifted, freeing the upper by the flange 46a and 52 of the members 50 and 45, and the opposite ends of the boards may be nailed to the door post 12. In like manner the ends of the boards 59 maybe inserted into the groove 5S provided by the flanges 47 and 57, and the opposite ends of the boards nailed to the post 13.r The main door B then may be closed and locked.

By the above described arrangement it will be appreciated that automatic means are provided for locking the door both at its upper and lower ends which means may be simultaneously disconnected to permit opening movement of the door. In addition, the door post is of such characterkas to permit of the engagement of the grain boards therewith without the necessity of nailing or bolting the same to the movable door post, and hence said door `post is of practically indestructible character and pro vides for eliicient and convenient operation at all times.
