CAR-DOOR.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application led Uctober 21, 1912. Serial No. 726,948.

i To all w'zom t may concern Be it known that I, FRANK J AGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Doors, of which the following is a specification, reference being made to the accompanying drawings.`

This invention relates to improvements in freight car doors and pertains more pari ticularly, though not necessarily exclusively, to what is known as anoutside door in this connection.

The principal vobject of my invention is the provision of improvements in outside doors of a railway freight car, by means of which the doors are rendered positively water-tight and burglar-proof. Another object is the provision of a novel fastening or sealing element applied to a door of the class described lwhich when closed effectually prevents the entrance of water or cinders into a car between the door proper and the door-,posts or car siding. A Vfurther object of my invention is to provide against the tendency present in moving cars having the usual outside door to side-swipe external objects. A still further object is to provide an improved car door having no involved parts to get out of order, and one which is simple, durable, and economical in construction, and eflcient in operation.

These together ,with such other yobjects as may hereinafter appear or are incident lto my mventlon I attain by means of a construction illustrated in preferred form in the accompanying drawings, wherein z- Figure 1 is anelevation of the loutsideof a door embodying my improvements, shown in closed position.v

Figures 2 and S'are vertical and horizontal sectional views respectively of Figure 1.

Figure 4 yis an enlarged sectin of the hinged closure member, and Figure 5 is a slight modification thereof. 4

Figure 6 is an enlarged detail drawing of a portion of the closure member, showing the clamping means.

It is well known that vinside doorsl as a rule occupy much needed room in freight cars, and that mainly on this, account outside doors are frequently desired and used 'inasmuch as they do notencroach on load- It is also well known that suchl ing space. i an outside door has many disadvantages 1ncident to its use, and that the main disadvantage is the diliiculty encountered in providing against the entrance of water E and foreign mat-ter between the door and car-body. This condition is rendered a certainty when door posts or other car frame members warp, leaving an Vopening between them and the door and leading to the possible damage of freight within the car.

My improved door is primarily designed to overcome this disadvantage, and to this end I provide a fixed inclosure for the reception of one end of the door, and a movable closure for thel other end, so arranged and positioned that when the door is closed it is to all intents and purposes sealed against the entrance of rain and foreign substances.' Then in this position and the movable closure locked, the door cannot be prled open for the purpose of pilfering Areight should anyone tamper with and loosen up any of the brackets; and from the foregoing it is obvious that the door cannot side-swipe external objects, should it by any means work loose from its lower fastenings when the movable closure islocked.

carrying out my invention I show a frelght car provided with an outside door 7 adapted to cover the entire door-opening and to rest against the two door posts 8, 8a whenclosed, and slidably supported on the rail or track 9, preferably'of Z-bar shape, by means of the hangers 10 of any `pre- Iferred type. Bolted to the lower extremity of the dopr, which extends below the threshold of the car, are wedge shaped members 1l which are positioned to engage with and wedge against the beveled faces of shoes or brackets12 on the car Vsiding 13 when the door is given movement to closed position, so that the door will be brought flushvwith and against the door posts, and also guided in such a manner by these members that the front end of the door will fity within a recess formed by a. vertical Z-bar 14 secured to one of the door posts 8, this closing movement being facilitated and further guidedby the beveled outer flange 14:a of the member 14. Y

From the description thus far given and in viewof the preferred construction illus- -shed formed by the horizontal liange 9 and the depending flange 9" of the v'rail 9; that -trated inthe drawings, it is apparent then the lower extremity is held tight against the car body 18 by the wedges 11 and brackets 12 as in the manner described; and that the front vertical edge of the door is received within a channel formed by the door post and the flanges of the vertical Z-bar 14, which channel suitably faces inwardly toward the door-opening as shown and eX- tends from the track to a point below the threshold 21.

In order to provide a weather-tight joint at the other vertical edge oftlie door, or in other words, at the vital point of contact between the inner face of the rear end of the door and the adjoining door post 8a, or other car body member, I have devised a fastening or sealing clement substantially coextensive vertically with the door and adapted to have swinging movement thereon to a position against the car siding 13.

To this end I provide a novel movable closure 15 substantially of angle iron shape as shown and connected at 16 to a leaf 17 preferably bolted to the outer face of the rear end of the door 7, though it is understood that it may be secured to the door' in any desired manner.v The door post 8a projects slightly outward beyond the vertical plane of the car siding, and preferably has its outer' edge cut away to conform with a corresponding beveling of the outer edge of the' door, so that when the door is closed and the closure swung inwardly against the car siding it is laterally inclined thereto and positioned in a direction corresponding with the opening movement of the door, such inclination tending to reduce direct shock to the hinge 16 incident to switching as will be understood. The closure 15 carries a lug 18 formed on the free edgeof the flange portion 15a of theclosureysaid lug being slotted to receive astaple 19 on the door post or car siding,

and is locked by means of aI slotted pin 20 perforated for the reception of the customaryl seal; If desired the door may vbe additionally clamped at its forward end,

IVith the above construction it is apparent that the rear end of the outside door is adequately protected against the most severe weather conditions, in that the angular closure extendsdownwardly from the track-f- 9 to a position on a line with or below the threshold 21, and is also conformed to rest against and cover in contiguous outer portions of the door and the car framework. In the opening operation the pin is removed and the closure swung outwardly, permitting the door to slide longitudinally the carl to a position clear of the door opening, Athis sliding movement being limited by-the usual stop member (not shown). i

The door is adapted to have easy movement on the track, as I preferably/'provide the hangers 9 with anti-friction rollers positioned to engagey the track on its upper and under surfaces, thereby eliminating any 0pportunity pressure is applied to move it.

I do not restrict myself to the exact embodiment as shown, as itis obvious that certain structural .variations may be made, such as for example, the door post may not project outwardly as described but be flush with the car siding, or the closure may be a straight member instead of angle iron shape. Any such and similar variations as these are deemed within the scopeof my invention subject to the limitations imposed by the state of the prior art. y i

Having thus described myinvention and illustrated its use what I claim as new and desire to obtain by Letters Patent is the fol-v lowingzs y In a railway box car, the combination with the doorway frame and its opening, ot' a door body to close the opening and having its rear edge beveled to form an inclined surface, and a movable lock 'and closure member pivoted on the door to swing inwardly against the said inclined surface and having a portion thereof offset to bear against and engage the doorway frame.

for the door to stick or bind whenl In testimony whereof I khave hereunto y signed my name'in the presence of thetwo subscribed witnesses. u i FRANK JAGER,
