HENRY J. TIERNEY, OF DENISON, TEXAS.

SLIDING DOOR FOR RAILWAY FREIGHT-CARS.

Application filed July 9, 1913.

To all ivhom it may concern Be it known that I, HENRY J. TIERNEY, a

citizen of the United States, and a. resident of Denison, county of Grayson, State of Texas, have invented certain new and useful.

injury and so that the edges of the door opening, when the door is closed, may be more effectively guarded against the entrance of moisture, dirt and cinders.

The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred form in the accompanying drawings and more particularly pointed ont in the appended claims.

In the drawings, Figure 1 is a side elevation of a portion of a railway freight car illustrating the improved construction. Fig. 2 is a horizontal section taken on the lines 22 of Fig. 1. Fig. 3 is a detail view illus crating one of the-rollers for supporting the sliding door, parts being brokenaway and shown in section on line 3-3 of'Fig. 6. Figs. 4:, 5 and 6 are vertical sections taken on the lines H, 5-5 and 66, respectively, of Fig. 2. Fig. 7 is a view similar to Fig. 6, illustrating a modification. Fig. 8 is a de tail view of one of the supporting rollers for the door shown in Fig. 7, with parts broken away and shown in section on the line 8-8 of Fig. 7

The side wall of the car comprises, as usual, an outer sheathing 1 and aninner lining 2 extending between the sill 3 and the car plate 4. The central portion of the side wall of the car is provided with three posts extending between the sill and plate, and which may be designated as a front post 5, a rear post 6 and an intermediate post comprising separate inner and outer members 7 and 8. These posts project outwardly beyond the outer side face of the car, while their inner faces are in alinement with the inner surface of the lining 2,,the front and rear posts being provided with tongues 9 Specificationof Letters Patent.

extending between the outer sheathing 1 and the lining 2 and having depending portions overlapping the outer face of the sill 3,

The separate inner and outer members 7 and 8 of the intermediate post are spaced apart, as shown, and the outer post member 8 extends downwardly over the outer face of the sill 3. As shown in Fig. 5, the ends of the post members 7 and 8 are arranged in suitable flanged seats formed in brackets 10 and 11 which are secured respectively to the car sill and plate. As shown, the bracket 10 is shaped tofit over the upper and outer faces of the sill 3 and is secured thereto by bolts 12. The bracket 11 abuts against the under face of the plate 4 and is provided with an upstanding flange 13 which abuts against its outer face. One or more bolts 14; extending through the flange and the plate secure the bracket in position. Similar flanged brackets 15 and 16 are also preferably provided at the upper and lower ends with the front and rear posts 5 and 6.

The space between the front post 5 and the intermediate posts 7 and 8 forms the door opening. Thespace between the intermediate posts 7 and 8 and the rear post 6 is inclosed by an outer sheathing 17 and an inner lining 18 to form a compartment for receiving the sliding door. As shown, the posts 6, 7 and 8 are provided with rabbets 19 for receiving the sheathing 17 and lining 18, so that the inner and outer faces of these parts are in alinement. The car floor 20 or a transverse threshold 21 forming an extension of the floor, projects outwardly through the door opening and is flush with the outer faces of the posts 5 and 8. The sheathing 17 preferably extends down below the level of the car floor, as shown in Fig. 4:, and a filler block 22 is arranged between the lower portion of the sheathing and work is covered by an outer sheathing 28;

Strengthening metal strips 29 and 30 are secured to the outer face of the door, as shown in Fig. 1 and an angle bar 31 is secured to the upper edge of thecross-piece 25, as shown in Fig. 4. The angle bar 31 is arranged opposite the bar or strip 29 and these bars are preferably set into the inner and prises inner and outer bars 32 and 33 which rest upon the car flooring and threshold 21 and are secured in place by bolts 34 extending downwardly through the car sill. Op posite the door opening the outer portions of the bars 32 and 33 are inclined, as shown. The bar 35, secured to the lower edge of the door, is preferably Z-shaped in section and has an upturned flange, which is preferably recessed into the outer face of the door and a downturned flange 36 extending into the groove or recess between the bars 32 and 33. Bolts 36, (see Figs. 1 and 3) extend through the upturned flange 35 of the Z-bar and se cure it in position on the lower edge of the door. The bars 32, 33 and 35 not only serve to guide the movement of the sliding door, but also act to prevent the entrance of moisture and dirt atthe lower edge of the door opening when the door is closed. v a

The door is supported on rollers, so that it may be readily shifted. In the forms shown in Figs. 1, 3 and 6, brackets 37 are arranged in cut-away portions or recesses in the lower edge of the door and are riveted to the horizontal portion of the Z'-bar 35. A; roller 38 mounted on each of these brackets extends downwardly through an opening 39 in the horizontal portion of the Z-bar 35 and engages the bar 33 which forms a track therefor. The pintle 40 of the roller extends through the flange 35 of the Z-bar and through a plate 41 arranged against the inner face of the bracket 37. A narrow front plate 42 is arranged against the outer face of the bracket 37 and above the flange 35, and is held in position by bolts 43 which extend through the lower portion of the door and through the rear plate 41. A second pair of bolts 44 extend. through the lower portion of the door and through the rear plate 41 and the flange 35. When the door is thus supported by rollers at its lower edge, its upper edge extends into a recess formed between an inner horizontal bar or header 45 secured to the under side of the car plate 4 and an outer, door-retaining bar or block 46 secured to the outer face of the plate and extending downwardly over the upper edge of the door.

In the form shown in Figs. 7 and 8, the

upper edge of the door is arranged between door does not extend to the upper edge thereof. The hanger. bracket 50 overlaps the inner face of the piece 23 and is secured to the door by bolts 51. The track flange 49 projects outwardly over the upper edge of the horizontal piece 23 and the upper portion of the hanger 50 is ofiset and abuts against the inner face of the outer sheathing 28. The extreme upper portion-52 of' the hanger is of inverted U-shape and the roller 53 is connected thereto byv a pintle 54.

The hanger 50 is also preferably provided with a guide lug 55 which is arranged to en gage the under side of thetrack flange 49 in case the door is raised when it is shifted. This prevents the rubbing of the cross-piece 23 of the door against the underside of the track flange. In both forms,the upper and lower portions of the door. are properly guided and the upper and lower edges of the door opening are effectively guarded against the entrance of dirt and moisture when'the door is closed. Furthermore, in both forms, the parts of the hangersare guarded against injury.

The forward edge of the doorfwhen in closed position, as shown in Fig. 2, extends within a recess formed in the face of the front post 5. Preferably, as shown, this post is provided with a laterally projecting portion 56 which overlaps the outer face of the door when the latter is closed- An inner strip or bar 57 is secured to the face of the post 5 adjacent its inner edge and when the door is closed, its forward edge extends betweenthe parts 56 and57 and thus effectively protects the forward edge of the door opening. The-door is of such width that its rear edge projects well within the space between the posts 7 and 8 when the door is closed. To further protect the rear edge of the" door opening against the entrance of dirt and moisture, the door is preferably provided with a vertical guard strip 58 which is secured to its outer face adjacent its rear edge. A coiiperating guard strip 59 is secured tothe face of the post'8 and projects inwardly beyond its inner face, "as.

shown in Fig. 2. In the closed position of the guard strip 59 overlaps and is arranged closely adjacent the forward edge of the guard strip 58 to prevent the entrance of dirt and moisture.

To further guide the shift of the door and prevent it from binding, two pairs of guide rollers are preferably arranged within the compartment between the intermediate and rear posts. As shown, the inner and outer side walls of this compartment are provided with horizontal braces 60 and inclined counter braces 61 extending between the rear and intermediate posts. The guide rollers 62 are mounted on vertical bolts or axles 63 which extend through the horizontal brace bars 60. Preferably, as shown in Fig. 4, the rollers are j ournaled in sleeves 64: which are arranged upon the upper ends of the axle bolts between the heads thereof and the upper edges of the horizontal members 60. When the door is moved rearwardly, to open position, the bars 29 and 30 thereon which project to a slight extent beyond its inner and outer faces, engage the rollers 62 and effectively prevent the binding of the door.

The front of the door adjacent its forward edge is provided with hand holes 65 and cooperating lock members 66 and 67 are mounted respectively upon the outer projecting portion of the front door post 5 and the face of the door adjacent its forward edge.

In the improved construction, all parts of the door are effectively guarded against injury and the parts are so arranged that the door opening is fully protected against the entrance of dirt and moisture.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims.

I claim as my invention 1- 1. A railway freight car having in its wall front, rear and intermediate posts flush with its inner face and projecting outwardly beyond its outer side face with a door-opening between said front and intermediate posts, said intermediate post comprising inner and outer members, said outer member extending downwardly across the outer face of the car sill, an outer sheathing and an inner lining between said intermediate and rear posts forming a compartment, and a roller supported door movable across said opening and into said compartment, substantially as described.
