avwentoz THOMAS J. GALLERY, OF ll FREIGHT-CAR-CLOSING DEVICE.

Application filed may 18,

To all whom it may concern Be it known that I, THOMAS J. GALLERY, a citizen of the United States, and resident of 299 Seventh St., Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improve ments in F reight-Car-Closing Devices, of which the following is a specification.

This invention relates to freight car closing devices.

One of the objects of my invention is to provide collapsible means for use as blocking within the car adapted to prevent cargo from shifting and moving toward the door sides.

Another object of my invention is to provide collapsible doors for closing the car, and so arranged that when collapsed they may be swung out from the car, so as not to interfere with the loading or unloading operation.

A further object of my invention is to provide in connection with the collapsible blocking device, means for rigidly securing it in sections to the car structure.

A further object of my device is to provide in connection with the collapsible doors, supporting, suspension and guide means for facilitating the operation of the doors.

A further object of my invention is to provide interlocking door units hingedly connected with each other and so arranged as to overlap at their ends, so as to prevent rain from entering the car.

The foregoing and still further. objects will be fully understood from the following description and the accompanying drawings forming part of this specification in-wh1ch:

Referring to the drawings, numeral 1 represents the u per or roof structure of a freight car. umeral 2 indicates the lower or floor structure of a freight car.

Within the car and hingedly and permanently attached to the car ends, as indicated at 5, and opening toward the center and closing toward the ends of the car, is a lazy-tong blocking indicated at 6, arranged in sections. At the end of each section there is provided a double acting locking bolt 7, adapted to engage the upper roof structure and the bottom or floor structure of the car, when the blocking is in open position.

In order to facilitate the locking of the bolt, a hand lever 8 is provided, which when turned upwards unlocks the bolt, and when swung downwards causes the bolt to enter into the sockets provided in the roof and floor structures.

This lazy-tong blocking becomes of great importance in preventing the cargo from shifting within the car, and particularly from moving toward the doors, whereby the closing and o ening operation of the doors I of the car while units 11 ,hingedly connected member 17. The ends 18 of rail 16 are similarly hinged at 19 as are end rails 14: at 15, and are also adapted to swing out of the car.

When the door sectlonsv 11 and 9. are

folded together as shown in Fig. 2 and when they reach their respective car ends, as clearly shown in Fig. 12, they may be swun out in the manner indicated in Fig. 13. y swinging the doors out in this mannor, the loading and unloadlng operation is greatly facilitated, insofar that the sides of the cars-are entirely opened,

The lazy-tong blocking 6 may also be swung out in a similar manner as shown in Fig. 1 (at the right hand side) when collapsed.

The door sections or units are hinged together in such a manner that end section 9 and the adjacent sections 11 swin outward with their hinged edges 20. T is is accomplished by providing hinges connecting the two .sections within the car, as indicated at 21.

The next section is again connected to the first section 11 by outer hinges 22. The

pins 23 and 23' of the upper and lower hinges are preferably connected with suspension means 12 and supporting means 17, respectively, whereby the edges 2% of these two sections are held within the car while edges 20 are swung out.

At the center sections there are provided convenient locking means 25, by means of which thedoor halves when closed may be drawn together and locked. The edges of each section are so arranged that they overlap or interlock with each other in order to prevent rain from entering the car.

The shape of the units may vary according to desire as shown in Figs. 6, 7, 8 and 9. In Fig. 7 the door sections comprise sheet metal strips 25' provided with a longitudinal groove 26 and an upturned portion 27 with an edge 28, registering with groove 26. In Fig. 9, the door sections are composed of sheet metal strips, the edges of which are formed into hinges, as indicated at 29. In Figs. 6 and 8 there are shown door sections made of corrugated metal,

hingedly connected in the same manner as the previously mentioned sections, however, so arranged that the last corrugation of guide 40.

each section matches with the last corrugation of the adjacent section, as shown at 30. Figs. 5 and 6 also illustrates another manner of suspension ofmy cardoors, arran w: within the car as indicated at 31. This suspension roller glides upon inner rail 32.

Referring to Figs. 10, 11, 12, and 13, the arrangement of my sections 9 and 11. is clearly shown, and particularly how the hin cs 10, 21, and 22 are arranged. In Fig. 10 t e suspension arranement of my door sections may be seen were a roller 33 is shown supported by suspension rail 13. The bearings or the roller 33 are provided in a clip 3% whichextends below suspension suspended by pin 23 which passes through hinge 22, and is provided with a head 38, a washer 35 and a cotter pin 36. I

In Fig. 14 is shown a referred form of my suspension means w ich is somewhat similar to the guide means in Fig. 10, but instead of a roller 33 as shown in Fig. 10, a horizontally arranged guide roller 39 is shown glidlng in a recess by a suspension From the roller is again suspended the hinged'bolt 23 provided with a washer 35, a cotter pin 36, while a head 41 supports the weight of the door section.

The suspension and guiding or supporting means may be also arranged at the center of each door unit, as shown in Fig. 15. In this case, the end units 9 are not hinged to the end posts of the car, but all the units are hingedly connected with each other. Each of the sections swings, when opening and folding the door, upon a pin so that one half of the units turn inwards, and the other half outwards.

While l have shown a specific construct on of my door sections and their suspenslon and support means, be it understood that changes and improvements may be made within the scope of my invention, for which I claim:-
