10 Claims.

This invention relates to doors for stock cars.

It is common practice at the present time to make such doors of wood. They usually consist of wooden stiles and rails with spaced transverse These slats are frequently broken by the animals within lthe car and to renew the saine, itis necessary to remove the doors. One feature or" this invention seeks to eliminate the necessity for removing the door, when itis desired to replace a broken slat.

Some doors oi this character use metal binding strips over the outside of the door and these binding strips must be removed before a broken slat can be replaced. This invention also overcomes this objection.

A further objection to present doors for stock cars lies in the locking arrangement which generally consists ofv staples upon the door posts and hasps upon the door for engaging staples. It will readily be appreciated that the bottom of the doormust be pulled outwardly to pass the staples and as the doors are moved past the staples during their opening and closing movements they become chaied by such staples with the result that it becomes necessary to renew parts of the door in a very short time. Another feature of this invention resides in means for eliminating such chafing of the inside of the door.

The lower margins of doors for stock cars are usually secured by chains that allow the doors to be pulled outwardly a limited extent. These chains usually become tangled and retard the movement of the door. This objection is eliminated in the use of single links or the like.

It also frequently happens that the bedding and refuse in the stock cars becomes frozen to the door and door, making it impossible to operate the door. To overcome this objection a metal chang strip lis attached to the lower margin of the door.

The invention comprises the novel structure and combination of parts hereinafter described and more particularly pointed out and dened in the appended claims.

In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views:

Figure l is a fragmentary side elevational View of a stock car embodying a door involving this invention.

Figure 2 is an enlarged and brokensectional view taken upon the line II-II of Figure 1.

Figure 3 is a view similar to Figure 2 showing the door in its pulled out position.

Figure fi is an enlarged fragmentary sectional view taken upon the line lV-IV of Figure 1.

This application is a division of co-pending application, Serial No. 356,971-, filed April 22, i929, now Patent No. 1,925,375, dated September 5, 1933.

The door involving tfi'is invention comprises a frame consisting ci an upper metal rail l, .which is shown in the form of a Z bar, a lower metal rail 2, which is in the form oi a T bar and metal lo side Stiles which are in the form of angle bars. These frame members are suitably secured together. To the lower corners of the frame are secured gusset plates d. To the upper corners of the freine are secured roller hangers 5. Dlag- 15 onally arranged metal braces 6, which cross each other at approximately their central points, connect the gussets d with the hangers 5. Transverse wooden slats "i in spaced relation are removably bolted to the stiles :i and braces t by 20 removable bolts 8. lt will be noted that the slats are seated in the angles of the stiles and are protected thereby. Consequently, if a slat becomes broken it is only necessary to remove the bolts t and take on" the old slat and replace the same 25 without removing the door from the car.

Between the door posts Q (Figures l and 4) there extends a rod i@ which is attached to the Z bars il which are attached to the posts. A second rod l2 is attached at its forward end to the rear Z bar il and extends rearwardly a distance substantially equal to the width of the door where it is attached to the side of the car as indicated at i3. In alinement with the attaching means it, are stops tl for arresting the 35 door in its open position.

The front end of the lower rail 2 carries a link i5 that encircles the rod l0 and the rear end of said rail carries a second link it that encircles the rod i2. This second link i6 is somewhat shorter than the rst link since it will be noted that rod i2 is. positioned outwardly from the rod lil.

The door is latched at its front end by a hasp li' which is secured to the door and which en- 5 gages a staple I8 on the front door post. The rear end of the door is latched by a jointed hasp i9, one section of which is anchored upon a staple 2t upon the rear side of the rear post 9 (Figure d). The other section of the hasp It engages a staple 2i upon the door. It will be noted that the joint ita of the sections is 'approximately opposite the rear corner of the door. This jointed latch tends to hold the door inwardly. When it is desired to open the door the hasp I9 is 55 door involving this invention eliminates many of the objectionable features of stock car doors heretofore used, and at the same time facilitates the repair of such doors.

We claim as our invention:

1. In a stock car, a pair of spaced rods, a sliding door, said rods extending in the direction of opening movement of said door, a link upon the forward end of said door and encircling one rod, and a link upon rear end of said door encircling the other rod, said links moving along said rods during the sliding movement of said door. i 2. In a stock car, a pair of spaced rods, aV sliding door, said rods extending in the direction of opening movement oi said door, a link upon the forward end oi the door encircling one rod, a second link upon the rear end oi said door encircling tlie other rod, said links moving along said rods during 'the sliding movement ci said door, and a chai-lng plate upon the inner lower surface oi said door.

3. In a stock car, a sliding door having a lower rail, a single link pivoted to the forward part of said rail, a longer single link pivoted to the rear portion oi said rail, a guide rod extending in the direction of opening movement of said door upon the car for receiving the first link anda second guide rod on the car extending in the direction or opening movement of said door spaced outwardly of the rst guide rod for receiving and guiding the second link, said links moving along said rods during the sliding movement of said door.
