DOOR CONSTRUCTION FOR RAILWAY-CARS.

Application filed July 23, 1915.

Z '0 all whom 2'25 may concern Be it known that I, HENRY J. TIERNEY, a citizen of the United States, residing at Denison, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Door Constructions for Railway-Cars, of which the following is a specification.

My invention relates to the construction of railway cars, and more particularly to door constructions for box cars.

One of the objects of the invention is to provide a novel and improved form of out side door which will be grain-tight so that when the car is loaded with grain no supplementary grain door will be required.

A further object is to provide a door which, instead of being supported outside of the wall of the car, on hangers for example, is arranged to move back and forth across the door opening in a plane within theplane of the outside of the car wall, thereby eliminating all hangers, brackets and other proj ecting members likely to become broken off or injured, insuring that the door be reliably supported on the car at all times, whether closed or open, and making it possible by means of certain devices which will be hereinafter described, to so engage the door with the door frame, when the door is closed, that a grain-tight fit will be made.

A further object of the invention is to provide a construction in which the door,

when opened, is moved between the inner and outer sheathing of the car wall.

A further object is to provide a car door with a novel and improved form of supplemental or relief door, adapted to be used when the car is loaded with grain, which may be readily opened to relieve the pres sure of the grain against the main door even when the pressure is considerable.

A further object of the invention is to provide certain novel means for forcing the door, when closed, outwardly against the door frame so that the door will be waterproof and grain-tight.

The invention has for further objects such Specification of Letters Patent.

Patented Oct. 31, 1916.

Serial No. 41,565.

other new and improved constructions, arrangements and devices relating to car door constructions as will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in the accompanying drawings, wherein Figure 1 is a fragmentary side elevation of the superstructure of a box car showing the. side door of the car and adjacent parts constructed in accordance with the principles of my invention. Figs. 2, 3 and 4 are sectional views taken on lines 2-2, 3+3 and 44, respectively, of Fig. 1. Fig. 5 is an enlarged fragmentary plan view in the same plane as Fig. 4. Fig. 6 is a fragmentary elevation, taken from within the car to show particularly the rear edge of the door, when the door is in closed position, and the parts of the car adjacent thereto. Fig. 7 is a fragmentary sectional view on line 77 of Fig.1. Fig. 8 is a plan view, and Fig. 9 a view, in perspective of a casting employed for holding in proper position the double door post at the rear edge of the door opens ing, together with certain other structural parts of the car. Fig. 10 is a view, in perspective, and Fig. 11 a sectional view, illustrating the corresponding casting at the lower end of said double door post. Fig. 12 is a view, in elevation, of one of the door rollers and its housing. Fig. 13 is a sectional view, on an enlarged scale, taken on line 13-13 of Fig. 1,,and Fig. 1 1 is a sectional plan on line 1414 of Fig. 13.

Like characters of reference designate like parts in the several figures of the drawings.

25 designates one of the side plates of the car, 26 the corresponding'side sill, 27 the flooring of the car, and 28 the roof. The side wall of the car is made up of the usual vertical posts, one of which is shown at 29, and outer sheathing boards 30 and inner sheathing 31. In the portion of the side wall to the rear of the door opening, that is, in the direction from the door opening in which the door is moved when opened, the usual diagonal strut is omitted and in place thereof there is a pair of such struts 32, 32 which are spaced apart. This section of the wall, therefore, provides a recess 33 for the door when opened. The door slides through a double door post or pair of posts 34, 35.

36 designates the post at the forward side of the door frame.

The door is composed preferably of an inner metal plate 37, an outer metal plate 38, and a filler 39 preferably of wood, the parts being secured together by rivets 40. One of the plates, the plate 38 for example, is formed at the forward and rearedges of the door with angular flanges 41, 42 which sheath the edges of the filler. The back plate 37 is formed with a similar flange 43 which sheaths the top edge of the filler. A Z-bar 45 is arranged at the bottom of the door, the lower vertical leg 46 of which projects back of the threshold plate 47 and between the same and a number of curved guide shoes 48 which are secured to the floor of the car just within the threshold plate. The horizontal flange 49 of the Z bar is formed with slots through which project rollers 50, the axles 51 of which are carried in housing members 52 secured to the Z bar. The threshold plate 47 is bolted to the flooring 27 of the car by bolts 53 which extend through a threshold extension timber 54 arranged outside of the side sill 26. The threshold plate is formed with an extension 55 which lies within the door recess between the inner and outer sheathing providing a track for rollers 50 when the door is moved in and out of the recess. Except at the places where the roller housings 52 are attached to the Z bar the lower edge of the inner plate 37 of the door is flanged over and attached to the horizontal flange 49 of the Z bar as indicated at 56 (Figs. 2 and 3.) The upper edge of the door. is guidedin a guide slot 57 formed between the side plate 25, a timber 58 bolted to the side plate on the outside thereof, and a strip 59 secured to the under side of the side plate. The forward edge of the door enters a groove 60 formed in the forward door post 36. A locking device, indicated generally at 61, is employed for holding thedoor in the closed position. This device is not described in detail as it is the subject matter of a co-pending application filed by me on the 23rd day of July, A. D. 1915, Serial No. 41,566.

The rear door posts 34, 35, are preferably supported at the bottom and held in proper spaced relation by means of a casting 62 (Figs. 10 and 11), resting upon and secured to the side sill 26 by bolts 63 and formed with a socket 64 for the outer post 34 and a socket 65 for the inner post 35. The casting is preferably formed also with a bracket 66 which supports the end of the threshold extension timber 54' above referred to. The

upper ends of the posts 34, 35 extend into sockets 67, 68 of a casting 69 (Figs. 8 and 9) secured by bolts 70 to the side plate 25 (Fig. 6). The casting 69 is formed also with a pair of sockets 71 to receive the ends of the diagonal strut members 32.

In order that access may be had to the door recess 33 in the side wall of the car, the lower inner sheathing board 31 is hinged to the board directly above it. lVith the car loaded with grain it is possible that the recess might otherwise become so clogged that s the door could not be conveniently opened.

Arranged at the rear edge of the door is a curved cam shoe 72 which preferably extends from the top to the bottom of the door opening and is supported by means of bracket castings 73 on a rod 74, the upper end of which turns in a bracket 75 formed on casting 69, the lower end extending through the sill 26 and being provided with a handle 76. The shoe, when turnedinto its operative position, engages the door and also the inner rear door post 35, which is pro vided for that purpose with a wear strip 77, and serves the double purpose of forcing the door outwardly against the door frame and closing the space between the rear edge of the door and the inner rear door post 35. By this arrangement the door construction is waterproof and grain-tight. Preferably a spring latch 78 is secured to the under side of the sill 26 which is so shaped and positioned that the handle 76 will pass under the same when the shoe is turned to its operative position, the latch preventing an accidental reverse movement of the handle. Its elasticity permits it to yield, however, with a sufficiently strong pull on the handle.

With a view to the employment of the car as a grain carrier, without a supplemental grain door, the door above described is provided with an upper small door 79 for loading the grain into the car and a lower door 80 which may be opened to sufficiently relieve the pressure of grain against the door, when unloading, to permit the main door to be slid back. The main door is formed with a recess 81 for the upper door 79, the metal plates forming the door being flanged over the edges of the wood filler around the door opening, as indicated at 82, 83. The flanges 82, 83 are formed at the rear side of the door opening with lips 84, 85 which are perforated for a seal pin 86, the latter extending through a perforation in the rear edge of the small door 79. The pin 86 is formed with a slot 87 and the lip 84 with a slot 88, which slots are adapted to receive any ordinary type of car seal. The lower small door 80 is of similar construction and when opened enters a recess 89 in the main door (Fig. 3). At the inner end of the recess 89 is an opening 90 which extends down through the bottom of the door, the purpose of this being to permit grain or other obstructions to escape from the door recess, thereby preventing the opening of the small door 80 from being interfered with.

Set into the forward edge of the main door so as to be substantially flush therewith are hand grips 91.

WVhen the car is used for carrying grain the grain will be loaded into the car through the upper opening in the door. In unloading the lower small door 80 is slid back into the recess 89 in the main door. The small door can be moved quite readily even though the pressure of grain against 'it is considerable because it is moved not against the grain but into the recess formed for it in the main door. When the pressure of the grain against the main door has been somewhat relieved in this manner the shoe 72 may be turned by handle 76 so that the rear edge of the main door is freed. The main door can then be slid back into its recess in the car w all. With the upper edge of the door engaged in the slot 57, the forward edge in slot (30, the lower edge-flange 48 of the Z-bar against the threshold plate 47, and the rear edge pressed against the outside post member 34L by the shoe 72, the action of which is, of course, to force the entire door against the door frame, an engagement is provided as between the door and the car which is waterproof and grain-tight.

A car equipped with a door of this sort may be used without any adjustment or changes for carrying ordinary merchandise as well as grain. When carrying grain no supplemental grain door is necessary. The construction, it will be seen, presents no projecting parts likely to be damaged by side swiping. The door itself is within the plane outside of the sheathing of the car when in closed position. l/Vhen opened for lading the door is completely housed within the wall of the car so that it cannot be damaged either from the outside, for instance, by a dray backing up against it, which happens not infrequently with the ordinary hanging outside door, or from within by careless handling of the cargo. The reliability of the door does not depend upon hangers. It is supported on a track laid on the floor of the car.

' Although the several improvements above described cooperate one with the other to provide a door having the advantages indicated, it may be possible tov utilize certain of said improvements singly or with less than all of the other constructions forming the invention in its preferred embodiment. Certain modifications in the form and construction of the parts might also be devised. For these reasons I do not wish to limit the invention to the precise constructions, de-

vices and combinations shown except as the claims appended hereto are expressly so limited.
