Application filed. June 19, 1923. Serial No. 645,389.

a freight car door in either an open orclosed position which is equally adaptable for use on both a single and double door.

The invention will be best understood from a consideration of the following detailed de scription taken in connection with the" accompanying drawing forming part of this specification, withthe understanding, however, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and moditied so long as such changes and modifications mark no material departure from the salie t pressed in the appended In the drawing:- I i Fig. 1 is a side elevation 01: a freight, car with my invention applied to the sliding claim.

' car doors.

2 is a vertical transverse section or the same. i Y

Fig. 3 is a transverse section of the track which slidably supports the car doors.

Fig. i is a view in perspective of the automatic latching means.

5 discloses detail views of the brackets in which the operating rod for the latches is mounted. 4

Fig. 6 discloses detail views of the sockets "for receiving the latching means.

7 shows a front and end elevation of th hangers for slidably mounting the doors on t 1e car.

Referring to the drawings, 1 designates areight car with a side opening closable by liding

doors

2 and 3, or a single door may e employed for the purpose when desired. irectly above the opening and on the outer .all e of the side of the car is secured a water guard 5 which extendslengthwise ot the car. As shown in 3, the waterguard is of angle iron construction with the flange secured to the wall of the car, while the other flange extends horizontally at right angles to the vertical flange for supporting the track 6. Spacer blocks 7 are likewise supported by the horizontal flange and positioned between the track 6 and the vertical flange o1 the water guard;

The track 6 and spacer blocks 7 are secured teatres of the invention as era by means of bolts or screws to the side wall of the car.

The doors are suspended from the tracks by means of cast iron hangers 8 secured adjacent the upper ends of the doors with rollers 9 rotatably mounted between the front plate of the cast iron hanger 8 and a rear return POIL-lOll 1O spaced from the front plate of the hanger 8. The rollers 9 are mounted on pins 11 secured in the U-shaped portion of the hanger. In order that the doors may ride'easily on the tracks 6, I have provided two grooved rollers in each hanger 8. v

The lower end ofthe doors is held in position and prevented from movement laterally from the side of the car by a guard rail 12 which is likewise of angle iron construction and secured to the outer wall 4 of the car.

Posts or door jambs 13 and 14 are mount ed vertically in the. side wall 4i of the carv and spaced from each other a distance to be spanned by the width of either

door

2 or 3. 1

A rod 15 is rotatably mounted on the outer side wall of the door 2by means of a pair of brackets 16 secured on said door and adjacent the medial line of said door. A pair of spaced

brackets

17 and 18 are secured to the door 2 adjacent the side edges.

On the opposite ends of the rotatable rod 15 are secured inwardly-projecting latch members 19 and 20 having upstanding lugs 21 for a purpose which will be described later. Secured centrally ot the rod 15 and depending downwardly therefrom is a hasp 22 wi'tha slot 23 in its lower end adapted to receive a. U-shaped or perforated keeper 2%. The U-shaped member 25. is adapted to be inserted through the keeper 2 l'tor maintaining the hasp 22 in position. A chain 26 secured at one end to the car door 2, and at its other end to the U-shaped member is adapted to prevent loss of said U-shaped member. I

The latch. members 19 and 20 may be welded or pinned to the ends of the rotatable rod 15, while the hasp 22 is welded to the central portion ot said rod and adapted to be oscillated between the brackets 16. The

brackets

17 and 18 are provided with laterally-extending lugs 2'? which project beyond the side edges of the car door 2 and ver the keepers 28 and 29, which are provided with pockets adapted to receive the latch members 19',- the lugs 27 limiting movement of the latch members 19 and 29. The

keepers 29 are provided with an upper and

lower pocket

30 and 31, respectively.

As shown in Fig. 6, a face plate 32 extending outwardly from the side edges of

thepockets

30 and 31 is adapted to be secured to the posts 13 and 14 when the pockets 30' 31 and provides a keeper adapted to engage the lugs 21 of the latch members 19 and for preventing outward movement of the doors when the lugs are so engaged with the respective keepers, whether the doors are in open or closed position.

As shown in Fig. 1, the keeper 28 on the left hand end of the door 2, which is engaged by the latch member 19, is located at a higher elevation than the keeper 28 engaged by the latch member 20 on the door 3;

The rotatable rod, 15, with its latch members 19 and 20 and the hasp 22. of the door 2, is similarly applied to the door 3 with the Xception that the rotatable rod 15 is located at a lower plane than the rod 15 of the door 2 so that the latch member 19 of the door 3 will engage inthe lower pockets31 of the keepers 29 instead of the upper pockets, as do the latch members, 20.

In the operation ofmy automatic latch-- ing means, the U-shaped member is removed fromthe keeper 24 when the hasp 22.

may be elevated, thereby rotating the rod 15 and causing the latch members 19 and 20 to be oscillated suiiiciently until they engage the lugs 2"? on

thebrackets

17 and 18, whereby further movement of the latch members will be prevented. In this positionof the latchmembers, the dooris free to be moved longitudinally of the car and carriedby the hangers 8 on the track 6.

Then the door 2 is moved sui'liciently to the right to close the opening, shown in Fig. 1,. after the latch members 19 and 20 have beenreleased-i'rom their respective keepers, latch member 20 will automatically fall into the pocket at the left hand edge of the door 3, while the keeper. 19 will fall into pocket- 30'now located at the left hand edge of door 2 in its present. position. The" latches are urged to locking position by the weightot the released hasp 22. The lugs 21 The keeper 28,. which is located to the right hand side of of the latches engaged by thelips 33 projecting over the mouths of the pockets 30, not only lock the door from sliding movement but: likewise prevent the bottom of the lease of the hasp 22 whereby door 3 will be locked again'strt'urther movement.

It is seen from the relative predetermined positions of the

cooperating keepers

2,8 and 29 upon oppositev sides oi" eachdoor and especially of the spacing of the keepers 29 adjacent the inner sides of! said doors'that the doors maybe locked with facility in" either a closedior open position.

Furthermora the spacing of the latches 19' and 2.0 equalingthespacingof the keepers 29 upon opposite sides of the opening in the side wall 4' of the caris a dominant'tactor in establishing the locked posit-ions, whether closed or open, oithe sliding car doors;

What is claimed is In a device of the character described, co-

operative doors slidableon tracks, spaced brackets secured to each door, a rod rotatably mounted in the brackets on eaehdoor,

arod on one door being located above the rod on the other door, latches secured to the opposite ends of each rod and adapted to normally project inwardly from opposite side edges of a door, a hasp rigidly connectedto each-rod for. rotating the same and for maintaining the latches in the normal inward position, a. keeper on the doors adapted to be engaged by the hasps for locking the hasps against movement to prevent rotation of the rods and releasing; the doors, keepers mounted in a fixed position relativeto the doors and in the path of the latches located in different horizontal planes forreceiving said'latcheswhen the'doors are-either in an open or a closed position, the keepers for engaging the latches being provided with means at different horizontal levels to -engage the'latches located at different levels-on the doors, lugs on the brackets projecting laterally from the sides of'the door for limiting the latches to a ready latching position withtheir respective keepers.
