do hereby declare that the following is a full, clear, and eizaet description thereof.

'10 My invention relates to new and useful improvements in doors, particularly those which are adapted. to be used on railway'cars to carry grain-or the like, or it may be used in conjunction with other types of structures including buildings.

It is particularly the object of the present invention to greatly improve and simplify the door construction shown in my United States patent, Se'rial'No. 105,534, filed June 2st, 1916, by forming the same of a fewer number of parts so that the door may be more readily placed in seating relation with its door opening or removed therefrom to permit access to the grain car or the structure in which the invention is used.

A further object of the invention is to provide a door carrying frame, with which doors 'of'various different thicknesses may be used, for instance, very thin doors for grain, cars and very thick insulated doors for refrigerator cars and the like.

in connection with the door carrying frame for holding the door, regardless of its thickness, in any one of several locked positions.

WVith these and other objects and advantages in view, the invention resides 1n the novel features of construction, combinat on and arrangement of parts which will be hereinafter more particularly described in the specification and claims and shown in the drawings, wherein:

Figure 1'is a side elevation of a portion of a railway car showing my improved door construction applied thereto.

Fig. 2 is a vertical transverse sectlon on the plane of the line 22 of Fig. 1.

In the accompanying drawing, although the invention is shown used on railway cars, it is obvious thatit is also adapted for use in connection'w-ith buildings and various other types of structures.

Therefore it has been shown on a car and will be described in this connection merely for the sake of illustration.

Application filed. March 1:, 191v. serial No. 155,481.

The car has a side wall land a top 2, t he eaves of which project beyond the side wall a sufficient distance to protect the door structure to a-conslderable extent from the weather, as will be evident from an ex mination'of Fig. 2. The side wall is provZded with a door opening 3, certain side of which are inclined to be engaged by the similarly inclined edges of a door 4 which is supported by a suitable door/carrying frame 5. f

A pair of track bars '6 and '7 are disposed above and below the door opening, they being spaced apart a sufficient distance to permit the door frame 5 to slide therebetween.

a The door carrying frame is hung from the upper track 6 by a pair of hanger brackets 8 having flanged wheels 9 rotatably mount' ed therein to directly engage the track. The lower track bar 7 merely acts as a guide for movement of the door carrying frame, and

to prevent the same from swinging out- Wardly, said frame having a pair of U- shaped guide members 10 depending from its bottom to straddle said track 7. This construction readily permits the frame 5, together with its door, to be slidably moved along-the side wall of-the car to completely clear the opening-3, orto be moved inthe reverse direction until. the frame engages 35 v the stop 11, in which position the door may 1 A still further object is to provide means be readily moved inwardly to close the openlng 3.

- The door 4 isheld within its frame 5 by means of the links 12, two of which are pro vided for each side edge of the door. One end of each link is pivoted to the edge of the door while its other end is similarly attached to the adjacent edge of the door carrying frame, and it will be seen from .95 Fig. 2 that the pivot members which connect the linksto the frame are disposed. in horizontal planes below similar planes passing through the pivot elements which attach the corresponding links-to the door. In this manner the door will be vertically raised when it is removed from its opening 3.

Thispeouliar manner of mounting the door within its frame permits the former.

to, be moved to either side of-th'e latter 011 the center of said door, thereby allowing the door carrying frame and its other parts to be positioned rather close to the side wall of the car. The considerable range of movement of the door is taken' advantage. of to 1 permit doors of various thicknesses to be yond the door opening, stops are preferably transversely of the door.

provided to prevent excessive outward move- ,ment of the door and also to aid a locking means to be hereinafter described, for holding the door in its several positions. When the usual thin door, such as shown in full liiies in Fig. 2 is used, pivoted stops 13 on the door carrying frame are swung into position to be engaged by the outer face of the door, as it is moved outwardly. Four or more of these stops 13 are pivoted to the outer face of the frame 5, these stops being so'c'onstructed that they may be swung upwardly' beyond the opening within the frame. They are held in their active position by means of the studs let which rest in notches in one edge thereof. After having engaged the stops, the locking means, to be presently described, will hold the door,

rigidly within its frame and prevent either inward or outward movement. In case a refrigerator car door is used with this same door carrying frame and is to be moved outwardly to the dot and dash line position of Fig. 2, stationary stops 15 are provided for engagement thereby. These stops are preferably in the form of righta-ngular members secured to the iimeredges of the opening in the frame 5, said stops projecting a considerable distance beyond the outer face of the frame. The length of these stops 1:") is dependent upon the thickness of the door, it being desirable to have the inner face of the door flush with the inner face of its frame as shown in Fig. 2.

The locking means for the door which is to be used for holding the same in either its'closed, or any one of various open positions, consist of a pair of sliding locking bolts 16 preferably disposed substantially The inner ends of these bolts'are pivotally connected to a lever 17 which is fixed to a short shaft 18 rotatably mounted in a suitable bearing extending through the center of the door. A handle 19 is carried by the outer end of this shaft for rotating the same and to rock the lever 17. A handle 20 is pivotally attached to the inner end of the shaft and is adapted to hang downwardly as shown when not in use. It is'obvious that rota: lion of the shaft in one direction will cause the bolts 16 to move away from each other to project their outer ends beyond the opposite side edges of the door, guides 21 on said door aiding the bolts in their sliding movements. \Vhen the door 4 is disposed in seating relation with its opening and the bolts are slid outwardly, their free ends will be engaged in eyes 22 extending from the wall of the car. This will effectively lock the door in closed position. The same sliding bolts if actuated in a like manner when the door has been moved outwardly into engagement with the stops 13 will be disposed in openings 23 formed in one arm of the stops 15. Ad-

ditional openings 2st are also formed in the stops 15 to receive said Sliding bolts when the door is moved to its most remote outward position or into engagement with the. stops 15, in which case said stops 13 will have been moved out of active position.

From the foregoing description, taken in connection with the accompanying drawing, it is obvious that a very simply constructed door carrying frame has been produced with which doors of various thicknesses may be readily used, and that an improved arrangement of stops has been provided for C0-- operation therewith. Furthermore. the relatively few number of parts of which the structure is composed will permit the same to be manufactured comparatively inexpensively and this feature also simplifies its operation to a considerable extent.

I claim 1. The combination with a wall having a door opening, of a door carrying frame slidaibly mounted adjacent the door opening, a door pivoted in said frame to swing to either side thereof or to be disposed in its longitudinal plane, and a locking means to hold the'door in either ofsaidthree positions.

2. The combination with a wall having a door opening, of a door carrying frame slidably mounted adjacent the door opening, a door pivoted in said frame to swing to either side thereof or to be disposed in its longitudinal plane, and stops to be engaged by the door when in either of said three positions.

3. The combination with a wall having a door opening, of a door carrying frame slidably mounted adjacent the door opening. a door pivoted in said frame to swing to either side thereof or to be disposed in its longitudinal plane, stops to be engaged by the door when in either of said three positions, and locking means to hold said door in any one of its three positions when in engagement with said stops.

el. The combination with a wall having a door opening, of a door carrying frame slidably mounted adjacent the door opening, a door pivoted in said frame to swing to either side thereof, stops carried by the frame to be engaged by the face of the door when the same is in various positions, one of said stops extending beyond the face of the frame farther than the other whereby doors of different thicknesses may be pivoted in the frame.

5. The combination with a Wall having a door opening, of a door carrying frame slidably mounted adjacent the door opening, a

door pivoted in'said frame to swing to either 1' side thereof, a stop pivoted to the outer face of the frame, a. second stop in the form of "aQright angular member secured; by one arm to said frame, the otherarm extending be yond the outer face of said frame, either of said stops being adapted to be engaged by the outer face of the door, doors of difierent thicknesses being thereby operable in said frame and locking means for holding the door in either of said positions yyhen engage ing either of said stops.

e. The combination with 9.! wall having, a, a door opening, of a carrying frame slidably .mounted ad acent'the door opening, a door- 'I have hereunto set my hand at Aniwa, in

11:11 plane thereof, stops for holding the door in the longitudinal plane of the frame,\ad-

ditional stops for holding the door beyond the outer side of said frame, and cooperat ing locking means on the door and frame for securing the former in either'of its last mentioned positions, said means being brought into operative relation When the door is moved laterally and outwardly on its links.

In testimony that I claim the foregoing the county of Shavvano and State of Wisconsin, in the presence of two Witnesses.
