FLUSH CAR-DOOR.
Specification of Letters Patent.
Application filed June 14, 1915. Serial No. 33,918
To all whom it may concern Be it known that I, EDWARD W. HAR- TOUGH, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Flush Car-Doors, of which the following is a specification.
This invention relates particularly to sliding doors for box cars,.and the object of the invention is a door which 'fits squarely between the door posts and flush with the side of the car in closed position.
The invention consists in the arrangement of track, guides, stops, door lock and other details of the sliding door construction shown in the accompanying drawings, and hereinafter described. What the invention consists in is more particularly defined in the appended claims.
In the drawings, wherein the same reference characters designate like parts in the several views,
Figure 1 is a side elevation of a portion of a box car, showing a door embodying the invention in closed position;
Fig. 2 is a plan view of the same, part of the roof being removed to disclose the door track and door arrangement;
Fig. 3 is a vertical cross-section through the side of the car and door, on the line 33 in Fig. 1;
Fig. 4 is a cross-sectional view similar to Fig. 3, illustrating the invention applied to another type of box car;
Fig. 5 is a detail side View of the door locking device;
Fig. 6 is a horizontal cross-section through the side of the car and door, on the line 6-6 in Fig. 1; and I Fig. 7 is a plan view of the side plate and track, showing the relative positions of the door and rollers with respect to the track when the door is closed.
In Figs. 1. 2, 3, 5, 6 and 7 the invention is shown applied to an ordinary wooden box car having wood siding 11 and roof sheathing 12, although it is not restricted to wooden cars. The siding is nailed at top and bottom to the side plate 13 and side sill 14, respectively, which are connected by the vertical door posts 15, and by the usual side posts and braces inside of the side sheathing. The
door 16 is suspended from a track 17 by means of two hangers 18, one at each upper corner of the door. The hangers are bolted to the outside face of the door, and project above the top of the door and edgewise beyond the ends of the door, and are provided with horizontal spindles projecting outwardly from their upper ends on which rollers or wheels 19 are journaled. The track 17 is channel shape'with the web vertical and the flanges facing in toward the side of the car. The upper flange has its edge bent up and secured to a spacing strip 20 which is nailed to the fascia board 21 along the eaves of the car. The rollers 19 run on the lower flange of the track, each roller having its own section of the track lengthwise thereof. and support the door clear of the side of the car except in closed position. The rollers are held on the track by inner guide strips 22, which are secured between the upper flange of the track and the spacing strip 20. and which project down along the inner edge of the top flange of the track.
At the front end. the track and guide strip are bent in toward the side of the car, and when the door is being closed. as the front roller approaches the front end of the track it is carried in toward the side of the car, thereby swinging the front end of the door into the door opening. In closed position the front end of the door brings up squarely against the front door post flush with the outside of the car. At the middle of the track. opposite the back door post. there is a switch portion 23 running in from the track toward the side of the car in a directionparallel to the front end of the track, and the rear roller runs on to this switch when the door is being closed, and is carried in toward the side of the car, thereby swinging the back end of the door into the door opening. The back end of the track beyond the path of travel of the back roller is bent in a ainst the side of the car in order to avoid a proiecting corner at the end of the track which might interfere with other equipment or obstructions along the right of way. The lower edges ofthe fascia board 21 and securing strip 20 are notched to receive the ends of the track and the switch.
The upper portion of the inside back edge of the door is beveled off at the same angle as that of the switch 23 in order to permit the upper corner of the door to clear the back door post. The lower edge of the door swings freely, and is guided clear of the car side and post by the Z-bar bottom strip 24. The web of the Z-bar is horizontal, fitting under the bottom edge of the door, with one flange secured to the lower front edge of the door, and the other flange projecting below the door opposite the edge of the car flooring boards Wear strips 26 are secured to the side of the car for the door to rub against in opening and closing. An angle clip or bracket :27 is secured to the back door post and side of the car below car below the middle of the door, and which can be swung up outside of the lower edge of the door and fastened to the door by means of a staple 29, to which it may be secured by a seal pin or by a padlock. The
staple 29 is secured to plate 30 which is sunk into the door to form a recess for the lever 28 and securing pin or padlock. In addition to the lever there is a securing rod 31 which is arranged longitudinally in the space below the bottom edge of the door in closed position, and which bears against the lower flange of the Z-bar and is held in place at the middle by the lever .28. The ends of the rod 31 are bent down to form cranks which are hinged to the side sill below the bottom edge of the lower flange of the Z-bar 24:. When the lever is unlocked and thrown down away from the door the rod 31 swings down out of the way of the door and rests on the tops of the short side sheathing boards 32 below the door opening. The lever 28 drops into a notch in the side sill where it is out of the way and protected from injury when the door is open.
The door has metal strips 33 s cured to its outer side along its front and back edges, which strips lap over the vertical joints between the ends of the door and the door posts 15 to keep out the weather. An angle bar 3 1 is secured along the top of the door against its inner side with the horizontal flange covering the top of the door and proj ecting outwardly below the track 17. This angle bar 3% stops water which may blow against the upper part of the door from finding its way over the top of the door and into the car. Horizontal angle bars 35 are arranged across the middle of the door to stiffen it. These angle bars 35 rub against the front of the back door post when the door is opened, and keep the middle portion of the door clear of the side of the car. ()ne of the angle bars 85 rubs against the middle wear strip 26.
A door stop consisting of an angle bracket 36 is secured to the inside of the door near its front edge with one leg projecting inwardly to engage against the front door step 37 ,to stop the travel of the door on its track at the end of its closing movement, and this same bracket 36 strikes against the back door post to stop the travel of the door at the end of its opening movement. To open the door the lever 28 is released, whereupon the bottom of the door will swing out, carrying with it the securing rod 31. The bottom of the door should swing clear of the back post so that the door can be shoved aside by a simple push, and the track will guide the top clear of the side of the car.
A header 38 is arranged across the top of the door opening between the door stops inch and the Z-bar 2% will support it from the side sill. The hangers 18 project up behind the track and will retain the top of the door in tight closed position whether it is supported on the rollers or on the side sill. The securing rod 31 will hold the bottom of the door in tight closed position so long as the lever :23 is locked up against it regardless of whether the door is supported on the track or on the side sill.
7 In Fig. a of the drawings the invention is shown applied to a car having a metal frame comprising a Z-bar side plate Q0. The web of the Z-bar side plate is vertical, with the top flange projecting inward and the bottom flange projecting outward. A horizontal metal plate ll is riveted to the outwardly projecting lower flange of the Z-bar side plate over the door opening and extending along the eaves of the car to one side of the door opening. The track 42 is channel shape with the web vertical and the flanges projecting inward, and the top flange is riveted to the under side of the plate 11. The track is bent in at the ends and provided with a switch 43, and the rollers for the door hangers roll on the lower flange of the track as in the construction shown in Fig. 3. The inner guide for the rollers is an angle iron lt, one leg of which is riveted to the under side of the plate 41 between it and the top flange of the track, and the other leg projects down inside of the roller pathway as in the construction shown in Fig. 3. The door opening may be framed in with wooden headers 45 and wooden stops 46 for the sides of the door. The operation of the door and fasteningmeans may be substantially the same as for the wooden car described above.
The invention isnot restricted to the details of construction shown and described.
