CAR CONSTRUCTION.

Application filed January 14,1926. Serial No. 81,193. I

My invention relates to car constructions,

ger oi opening of the joints between the edges of the car ends and the adjacent walls of the car, and wherein the .car end is joined more firmly to the adjacent walls than in structures heretofore employed.

Another object of my invention is to provide car end structure wherein improved means are provided for preventing passage of air or moisture past the edges of the car end to the interior of the car.

Another object of my invention is to provide a car end so mounted as to be movable out of closed position, ther'eby serving as a door for providing access to the interior of the car. I

Another object of my invention is to provide a door structure having an improved form of locking mechanism, and onewherem provision is made for'effecting a tight clo sure as operating door frame structure.

One form which my invention may take is shown in the accompanying drawing, wherein Fig. 1 is an end elevational v ew of a car with my invention applied thereto; Fig. 2 is a vertical sectional view on thehne 2-2 of Fig. 1; Fig. 3 is an enlarged elevational view of the locking mechanism; Fig. 4 is a section on the line 4-4 of Fig. 3, and 5 is a section on the line 5-5 of Fig. 1, showing the corner structure of the car at the hinge side of the door.

For convenience of description I have shown my invention as applied to a railway car end wherein such end is hingedly mounted to serve as a door to provide access to the interior of the car, but the invention is not limited to car ends nor to car ends that serve also as doors.

The door is composed of panels 11 and 12 riveted together at their adjacent edges and having marginal angles 13, 14, 15 and 16 riveted thereto.

The door is shown as supported against a framework composed of vertical angles 17 and 18 (Figs. 4 and 5) that are secured to the posts 19 and 20, respectively, a portion of the side walls of the car. A top frame member is also provided consisting of plates '21 and 22 (Fig.2) that are connected between the edges of the door and cov which form to the side wall structures of the car in any suitable manner. A bottom door frame structure consists of a plate 23 that is secured to the floor 24 of the car and the end sill or platform 25.

Four hinges 26 are secured to the door and to an angle iron 27 that extends vertically the full height of the door and is secured to the angle .18. A plate 28 is secured to the angle 14, such plate being provided with an outturned edge that cooperates with the inturned edge of the bar 27., thereby creating an overlapping structure which tends to prevent access otmoi-sture or entry of air past the edge of the door. 7

Three latch bars 30 (Figs. 3 and 4) are provided at the right hand edge of the door to hold the same closed. These latch bars are each pivotally mounted upon a pin 31 that is supported in bearings 32. which are fastened to the side wall structure of the car. The bars 30 are held in latched position by means of. locking pins 33 that extend through openings in the flanges 34 of keepers 35 that are secured to the face of the car end. The ripper ends of the locking pins 33 are bent over :33 so that the pin may be turned to the position indicated dotted lines in Fig. 3, and the end33 caused to rest upon a ledge 35 to thereby hold the locking pin 33 in raised position and permit the latch bar 30 to be swung outward.

The bearing brackets 32 are each connected to the forward end of a spring plate 36 (Fig. 4 by means of rivets 37., the spring plates in turn being riveted to the vertical angles 17 of the side wall. A verticallyentending angle bar :33 is disposed between the spring plate 3.6 and the bearing bracket 32 with its flange turned inwardly to overlap the outwardly extending flange of a vertically disposed angle 39 that is secured tothe door frame angle 13, thereby making .a tight joint between the edge of the door and the adjacent side of the car. The angle bars 33 and 39, when overlapped as shown in Fig. 4, serve as stop members tor holding the door closed. I i

A guide member 41 is provided for each latch bar 30, such guide member being rigidly secured to the angles 17 and 13.. .In order to open the door, the pin 33 is raised to the position shown by dotted lines in Fig. 3 and the latch bar '30 swung outward about its pivot 31 until its camusurface 30 is connected to three hinges 44 (Fig. 1)

are secured to the end plate 21. The outer 39 is brought into engagement with either the camming surface 30 of the latch bar or with the camming surface 32 of the support ng bracket 32, to force the angle 38 outward and a permit the angle 39 to assume the position shown in Fig. 4, at which time the lever30 can again be locked. 1 i

A sealing joint is provided at the top of the car by means of an angle 43 (Fig. 2) thap1 is t at edge of the angle 43 overlaps the door frame angle 16, as shown more clearly in Fig. 2, and

its inner end is turned upwardly between the plates 21 and 22 that extend across the end of the car. The angle 43 is connected totwo links 45, so that when it is desired to open the door, pins 46 by which the links are sup ported from the bracket 46 are removed from the brackets and the links lifted until their openings 47 are in position to be engaged by the pins 46 and the links then supported by bracket 46 in raised position, thus holding the angle 43 out of the path of the angle 16. When the outer edge of the angle 43 is swung vertically about its pivots 44, the inner upturned flange of the angle moves through an arc and is thus guided into and out of its seat between the plates 21 and 22.

At its bottom edge, the car end is provided with two pairs of ears 50 (Fig.2) that are perforated for the receptionof locking pins 51 which serve to retain holding levers 52 in locked position. The levers 52 are pivotally connected to an angle 53 that extends across the lower end of the car door and has its inner edge 53 interlocked with the edge 23 of the plate 23. The lever 52 is provided with a nose portion 52 that engages the bot tom angle 15 of the door, when in closed position, thereby holding the outer end of the angle 53 in elevated position. The overlapping edges 23 and 53 serve as a seal. WVhen the latch 52 is swung outwardly, the outer edge of the angle 53 drops clear of the angle 15, to permit opening of the door. A guide plate 54'is secured to the inner face of the door to bring it to proper vertical position when the door is being closed.

From the foregoing it will be seen that I provide a door that may be readily opened and wherein the edges are efiectively sealed.

The door possesses a still further advantage in that pressure of lading against the inner The door can then be moved to face thereof will not cause spreading of the joints between the vertical edges of the door and the car sides, by reason of the fact that the hinges and the latches cooperate as tie members to maintain the sides and the door of its plane, of an angle member secured to the door atone edge thereof, a spring plate secured to thedoor frame, and a plate car ried by said spring plate and normally overlapping the said angle member, the said angle member and the second-named plate being substantially co-extensive in length with the vertical edge of the door.

2. The combination with a door. frame and 'a door movable in a direction transversely of its plane, of a plate secured to the door at one edge thereof, a spring plate secured to the door frame, a: sealing plate carried by said spring plate, the sealing plate normally overlapping the first-named plate, and acainming member mounted in position to flex the spring plate outwardly to permit the other plates to clear one another, the said angle member and the sealing plate be ing substantially co-extensive in length with the vertical edge of the-door.

3. The combination with a door frame and a doormovable transversely thereof, of an angle at one side of the door frame and substantially co-extensive inlength with the ad jacent edge of the door, a plate secured to the door in position to abut against an inner surface of the said angle when the door is closed, a spring plate secured to the door frame and to the angle and arranged to yieldabl hold said angle at an inner position am in overlapping relation to theplate when the door is closed,and means for holdlll) ing said angle against movement relativeto i the said plate and for flexing said spring plate to move the angle out of said overlapping relation. 1

4. The combination with a door frame and a door, of an angle disposed along one ed e of said door, a second angle carried by said frame, and means for yieldably supporting one of said angles inposition to overlap the other angle, the said angles being substantially co-extensive in length with said edge of the door.

5. The combination with a door frame and a door, of an angle disposed along one edge of said door, a second angle carried by said frame, means for yieldably supporting one of said angles in position to overlap the other angle, and means associated with one of said angles for varying the relative positions of the angles, the said angles being substantially co-extensive in length with said edge of the door.

6. The combination with a door frame and a door, of an angle disposed along one edge of said door, a second angle carried by said frame, and means for movably supporting one of said angles in position to overlap the other angle, the said angles being substantially co-extensive in length with said edge of the door.
