Specification of Letters Patent.

Patented June 15, 1915.

Application filed August 16, 1912. Serial No. 715,344.

To all whom it may concern:

Be it known that I, FRANK JAGER, a citizen of the United States, and a resident of 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 had to the accompanying drawings.

railway freight cars and more particularly to an improved side door adapted for use in a box car or other similar vehicle.

One of the primary objects of this invention is to provide a door in a box car positively designed to close a door opening and prevent any leakage of grain or other material when the door is in closed position, and adapted to combine the functions of both a side door and a grain door, such as are commonly used in a freight car in grain carrying service. Another object of this invention is the provision of an improved the door is locked the car is rendered positively burglar-proof and tight against leakage of grain and the entry of water; and in general the provision of an improved weather-tight door in a railway freight car which is economical in construction and simple and effective in its operation.

These and such other objects as may hereinafter appear'or are incident to my inven tion I attain by means of a construction illustrated in preferred form in the accom panying drawings, wherein Figure 1 is an elevation of the inner face of a car door embodying my lnventlon.

Figure 2 is an elevation of the outer face of the door in Figure 1, showing a portion of the car body broken away.

Figure 3 isa vertical section on the line III.III and Figured is a horizontal sec tion onthe lineIV-IVof FigureQ.

Figures 5 and 6 are viewssimilar to those My present invention relates generally to of Figures 2 and 3 except that they show the folding closure, movable posts and locking plate member in open position.

Figure 7 is a section on the line VV of Figure 5. 7

Figures 8 and 9 are enlarged detail sectional views of the post and locking plate respectivel Figure 10 is a perspective view of a portion of the locking plate, taken at the lower right hand side of Figure 2.

In freight car construction it is common to provide cars with outside doors, which doors have sliding movement longitudinally the car before access may be had to the interior of the car for whatever purpose in hand. This general type of door has many disadvantages, principally among them being the inability to prevent the entrance of water and their liability when the car is in motion to side-swipe external objects. It is a commonpractice when a car is loaded with certain commodities liable to water damage to supplement the ordinary side door with a more or less temporary grain door secured to the posts in a manner well known. Such a practice is inconvenient and certainly expensive, and my improved door is primarily designed with the elimination of these disadvantages in view, and also at the same timeto provide a weather-tight door and a door which is burglar-proof, thereby lessening liability against claims on damaged or pilfered freight. To this end I have provided an unitary door structure suitably hung inside the car and covering the entire car door-way, which door is preferably provided with the three openings and closures as shown, together with guard means adapted to protect all vital door parts subject to weather, and certain novel locking means cooperating with the guard means in a manner more fully hereinafter described. These openings referred to above together with their respective closures are planned with special reference to expeditious loading and unloading of different classes of freight.

While I have shown my invention ap: plied to a railway box car it is obvious it is applicable to other types of vehicle conspect to the precise embodiment shown.

Furthermore, although in the drawings I show a door made of wood, it is equally obvious that it may be of some suitable metallic construction.

Referring now more particularly to the drawings embodying my preferred construction, I show a car body 10, carrying an upperdoor track 11, a lower track 12, a door guide 13, door posts 14, and door 15.

The door 15 is preferably composed of vertical frame members 16 and horizontal cross pieces 17, which are rigidly secured together. The door is suitably hung inside the'car by means of hangers 18 which are secured to the upper horizontal cross piece 17 and which engages with and has easy and positive movement along the track 11 which is mounted on the inside of the car above the door opening. 1 I- Iingedly connected at their upper longitudinal edges to adjacent cross pieces 17 and adapted to swing outwardly are closures A, B, and 0 covering corresponding ports in the door 15. These closures extend horizontally substantially the width of the door 15 and are ship-lapped at their vertical edges with the upright members 16 and also lapping at their lower horizontal edges with the' cross pieces 17 with the exception of the folding closure A.

The closure A comprises two sections a.

and b hingedly connected together at-their inner horizontal edges, the sections folding against each other when in open position as shown in Figure .6. The lower edge of one of the members'l6 carriesa shoe 19 which engages the inner vertical 'sideof the track 12. By using this folding door section A a greater opening in the door is thus obtained I as the folding door has no greater move- 5 1116111) on an arc than would the ord nary closurehave-when provided for. an opening substantially 'at the sides. Owing'to the restricted clearance between the car and ex- I isting facilities for unloading, the size of an ordinary door opening would be limited in view of this. This opening being thus greately enlarged permits the expeditious loading and unloading of ordinary wayfreight such as bales, largeboxes, etc., The

closure C is particularly adapted for the re- ,ception and fullmanipulation of grain spouts for loading and unloading such com modities as grain, and the closure Bis de-' signed particularly for loading coal" and. the like thereby eliminating unavailing expenditure of time and labor in these operations. These closures are ship-lapped at all points of contact with frame members as shown in thejdrawing at 21.

In order to prevent freight in the car from shifting and lodging'against the car siding and in this way obstructing any1slid-.

ing of the door longitudinally the car when .desired the guard 13 has been provided with fat this object in view. Theidoor has easy slidin'gmoveinent upon theiupper and lower the two door posts 11 and adapted to swing outwardly are a pair of movable posts 25 which are preferably beveled at 2 1 so that they may swing to their fullest extent outwardly and clear the door opening. Each of the movable posts 25-is provided with a vertical recess 26 adapted to receive the projecting edge 27 ,of the upright 16, thus hold ing the door against relative movement when closed 'When closed the vertical inner face 28 of each post fits snugly against the closures A, B and-C coveringthe ship-' lapped edges and holding them tight against their seats. V

The movable posts swing on hinges 29 and when closed the posts aretight against the door postslfl', uprights 16 and vertical edges of the-closures where they lap with the door frame members. Any wmoisture which may seep past the movable posts is caught and drained by the ducts 30 grooved in the posts 25. The movable posts are beveled at their lower ends to' conform with the shaped threshhold or sill 23 and extend integrally upward to'the track beam 31.

From the disclosure thus far made, it will readily be Seen that allvital parts are protected andcovered against the entrance of water or 'cindersbetw'een the door and the door posts, or through the edges of the. closures where they lapwith the door frame work. In addition to the functions already set forth the posts effectually relieve the closures against pressure exerted, against them from the load withinthe car, especially so is this true when theicar is loaded with grain'or coal. Secured to each movable post isone or more plates 32 provided with a projecting stud33 adapted toregister with and fit-into a correspondingaperture 34in the door post. By this means the hinges 29 are relieved of excessive pressure and the movable posts have easyswinging movement outwardly;

.The arrangement of movable posts and i a laterally sliding door having a smaller swinging door both of which are held closed by said posts, is more broadly "claimed in my co-pending application Serial Number" 730,632.. r V 7 Y The fastening means 35 .onthe closures and C are preferably. arranged as" shown. The. closure Acarries a lever 36 pivoted to the section 5 andadapted to operaterwithin a slot 37in the door posts 1 1. The movable 7 posts 25 are recessedat '38,to accommodate the lever andat thesame time whenclosed r effectually locks thisv lever :in place. A-short arm 39 pivoted at 40 to the outer faceof the posts 25 permits their ready opening.

To positively lock the movable posts and the door when closed I show a locking plate member i1 which is hingedly connected to a block ,42 bolted to the car sill by means of a link hinge 43. This locking plate member 41 is preferably of metallic construction and flares or is flanged upwardly at its free edges as at 48 and conforms with the threshold of the car, so that when the door 010? sures and movable posts are closed and it is swung upwardly the flanged edges 42 fit tightly, against the said members, locking them against any movement whatsoever. The plate being positioned to lie between the posts 25 prevents them being opened, and the projecting face 27 of the upright 16 resting within the recess 26 of the now immovable posts 25 eflectually hinders any relative movement of the door longitudinally of the car. 7

Furthermore, neither water nor cinders can possibly enter into the car at the threshold owing to the flanged edges of the lockingplate being flush with the door and posts protecting and covering the threshold and as the plate is inclined it affords excellent drainage facilities. The plate itself is held in closed position by means of a seal pin 13 operating in a slotted member 14% secured to the section b of the closure A. The pin projects over the flanged edge and a seal is then attached in the usual manner.

Nhen it is desired to retain any of the closures A, B, and C in their open position, a pin 45 carried by a chain or other flexible member 46 attached to the inner face of the closure is placed in a corresponding aperture 17 located in the door post.

The operation of the device is fully disclosed in the illustrations. Figures 2, 3, and 1 and Figures 5, 6, and 7 showing the door in closed and open position respectively. To

open the door break the seal on the seal pin a3, remove the latter and swing the looking plate 41 clear of the threshold. The filler block 42 accommodates the flanges 4:8 and permits the plate to drop into a vertical position out of the way. The movable posts are then easilyturned on their axes by means of the pivoted arm 39 and swing clear of the doorway. Any or all of the closures may then be opened by manipulating their respective fastenings, or if desired the door itself may be moved to clear the entire door opening. No freight in shifting can obstruct this movement owing to the guard 13 which prevents any such lodgment.

The entire constuction-is simple and economical, operates easily, takes up little space, and the cost ofmaintenance is reduced to.a minimum; There is an entire absence of involved partsor mechanism. I do not restrict myself to the exact embodiment scope of my invention.

Having thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following 1. In a freight oar having a doorway, of a car door within the car and adapted to close the entire doorway, a pair of movable posts on each side of the doorway pivotally mounted on a suitable support adjacent the door, and a locking device removably positioned in the doorway and extending between the said movable posts to engage with them when closed against the door.
