application filed may 9, 1907. Serial No. 372,655.

To all whom it may concern."

' State of Minnesota, have invented a new and Improved Car-Door, of which the following is a full, clearrand exact description.

' facility,

This inventionrelates to car doors, and the object of the invention is to produce a door which can be opened and closed with rent and which will operate effectivdi prevent theloss of grain or similar produce which sometimes occursthroug'h theicracks or small openings at the doorways of cars. I

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth.

inthe claims.

Reference-is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding-parts in all the figures.

Figure 1 is a side elevation of the'middle' portion of a car-body, representing the door constructed according to my invention and in a closed position; Fig. 2 is an inside elevation of the door and contiguous partsof the car body; Fig. 3 is a vertical central section through a door constructed according to my invention, and showing contiguous parts of the car body; Fig. 4 is a horizontal cross secand Fig. 8 is an edge view of the same, look-- tion through the doorway of a car and ado'or of a modified form; Fig. 5 is a front elevation upon an enlarged scale and illustrating the locking mechanism for the door of the preferred form; Fig. 6 is a horizontal cross section taken on the line 6-6 of Fig. 5, and further illustrating the locking mechanism; Fig. 7 is a front elevation of a portion ofthe modified form of door illustrated in Fig. 4;

ing. downwardly.

' Referring more articularly to theparts, 1

represents the bor y of a car having a door- .Way 2. In the preferred form of my invention, I provide two hinged doors 3and 4, the former of which is connected by a hinge joint 5 to the rear face of the door jamb, while the door4 is similarly attached by a hinge joint 6 at the other side of the door jamb. The edges of these doors are adapted-to overlap,

' as indicated in Fig. 2. The free vertical edge of the door 4 is cutaway'so as to'forin 'a 'plurality of'notches 7. located between the on jecting-ears 8. These'ears 8 are formed with bearings for a locking bar 9; this locking bar bly mounted in the ears 8, and between the ears 8 at the notches 7 the locking bar is formed with cranks 11. The-opposite edge of the 'door 3' is formed With projecting tongues 12which are opposite the cranks '11 and the ends of-these tongues 12 are bent overso as to form hooks 13 adapted to be engaged'by the cranks. Near the lower edge of the door the locking bar 9 is formed with a lateral]; projecting :lever 14 which is'for'ine'd with a orizontal extension 15 and connects integrally with an-inclin'ed extension '16,. as shown. The cranks 11 are substantially in the same plane as the lever 14. This arrang'einentenables the lockin bar to be rotated-s0 as to enable the cranh's 11 to been gaged withthe hooks or disengaged therefrom, as desired. When the lever 14 lies Fig. 1, the cranks are in engagement with the hooks so that the door 3 is latched against the door 4.

At the upper side of the doorway a transom or upper door 17 hinged, as shown, so as to swing inwardly as indicated in Fig. 3. The lower edge of this door overlaps the upper edges of the doors 3 and '4.

On itsouter face the transoin17 is 0 vided with an upwardly projecting hoo 18 which constitutes a keeper for a vertically sliding boit 19 which is attached in guides 20 secured to the outer face of the door 3 as shown. The lower edge of this hoodis provided with a downwardly extending flap 21, of leather, rubber or similar material, which constitutes a protection for their per edge of the doors 3 and 4, from the weat er. When the doors 3 and 4 are latched together as indicated in Fig. 3, the bolt 19 may be shot upward] so that its upper end projects' under the eeper Band in this way the transom or upper door 1? may be also latched in position.

'ally projecting finger 22'is provided, which is ada ted to strike the uppermost of the gui es 20 so as to limit the downward movement of the bolt. The lower end of the bolt against the face of the door 3, as indicated in Near the upper end of the boil; 19 a later-- 9 is formed with wrists 10 hich are rotata- '19 is formed with. an offset extension'Q-i which is bent laterally to form a handle or finger 24. By means of this finger the bolt may be rotated so that the finger may lie against the face'of the door 3, as shown in Fig. 1. In this way the'finger 24 and the horizontal extension 15 of the lever 14 ma be brought close together and .in parallelism,

' both lying on.the face of the doorway. 'When 6 face of the-door. When this slide 28 is slid upwardly, the locking finger or bolt 26 is withdrawn from-before the finger 24 and part 15, so 'as' to enable these pieces to be moved. The lower extremity of the locking finger 26 is provided with an opening 30 which enables a seal 31 to be applied, as indicated inFig. '1... When the car is to be used for shipping valuable freight, a seal will be applied at this point, and if it is injured or removed, it will indicate that the door has been 0 ened or tampered with. .IVhen the car is heing used to carry grain, the upper door or'transom 17 maybe left open; that is,

. door.

it will be swung inwardly and supported at its free edge from the roof or rafters of the car.

It may 'be' desired ,to lock the transom in a dosed position independently of the doors 3 and 4 for this purpose the'lower edge of the transom is provided at one end thereof with an opening 32. This opening is dis osed over thedoor jambas indicated in 1g. 2, and th e iamb is provided with an outwardly,

projectingstud 33 which is adapted to proect through the transom when the same is closed. This stud 33 is provided with an opening to receive a pin 34 which holds the door closed. This in for convenience, is attafihed by a smali chain 35 to the door am- 1 On the outer sides of the doors 3 and 4, near'the lower edges thereof, I provide downwardly projecting spurs 36 having horizontal bodies 37' rotatably mounted in bearings 38 projecting outwardly from the face of the These s urs are sharpened at their lower ends and lie adjacent to the sill of the door and near the car floor when, the doors are. opened inwardly. It will be observed that the doors 3 and 4 may be swung inwardly or, outwardly to 0 en them.

In Figs. 4, 7 and 8, I-il ustrate a modified construction of door which I ma employ for latching the sidedoors toget er. Re-

ferring to these Figs. 39 and 40 represent respectivelythe left hand and right-hand swinging doors, and these doors are attached )y hinges 41 to the door ambs 42 as shown. To the outer side of the door 39 near the free edge thereof, I attach a hook plate 43, the edge whereof is bent rearwardly to form a flange or hook 44'. On the opposite edge 45 of the door 40 which overaps the door 39, a locking plate 46 is at tached by a hinge joint 47. This locking plate 46 has a projecting toe 48.

The edge of the door 40 is offset outwardly, so that the doors are adapted to overlap eachother, as indicated in Fig. 8. When they are being brought into this overlapped position, the body of the locking plate 46 is rotated from right to left so that the toe 48 engages under the hook 44. In this way the doors are practically latched together, with the body of the plate 46 lying against the face of-the door 39. This plate may be then secured to the door 39 in any suitable manner. In both forms of the invention, the edges of the doors are rovided with weather strips 49 which tend to keep out the driving rain. 1

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

-1. In combination, a pair of swinging doors overlappin at their free edges when closed, a rotatabTe locking bar attached to one of said doors and affording means for latching said doors together, a third door cooperating with said first doors to close the opening of the doorway, a locking bolt for latching said'third door, and a member for locking both said locking bar'and locking bolt against movement.

2. In combination, a swinging door having a hook plate near the free edge thereof, a second swin in door overlapping the first, a rotatab e Tocking bar attached to said second door and having cranks, adapted to engage said' hook plate, a third door overlap ing the u pered es of said'first doors, a siding an rotataile bolt mounted on one of" said first'doors and eng ging said third door toylock the'jsame, sai lockin bolt havin al'ateral finger, a lever carried by said loc "ng bar, and means moving over said finger-and said lever and locking the same against movement.

3. In combination, a swinging door having a hookplate near the free edge thereof,

.a'second swingin door meeting the first, a

roiatable locking an attached to said second door and having cranks adapted to engage said hook plate, a third'door attached to the upper edge of the doorway and meeting the upper edge of said first door; a sliding and rotatablebolt mounted on said first-door and enga ing said third door to lock the same, sai bolt having a handle adapted to lie against the face of said first dooi, a lever carried by said locking bar and adapted to lie against the face of said first door adjacent to said handle, and a sliding member 5 attached to said first door and affording means for holding said handle and said lever against the face thereof.

In testimony whereof I have signed my I name to this specification inthe presence of twosubscribing witnesses.
