moves within the plane of the outer wall of 1 the car. Such attempts have not succeeded and have provedimpracticable for the reason that no proper provision was made for strengthening or reinforcing the car wall adjacent the rear of the door.

In the Christy Patent No. 1,068,318,.there is shown an attempt to make a door that isfiush with the wall of :the car and a metal panel adjacent the rear end 'of the car. This metal panel however is not incorporated in the car wall so as to transmit tension orcompression between the sill and top plate and consequently it does not reinforce the car. In the Carpenter Patent No. 1,094,835, there is illustrated another attempt :to make a fiush car door with a sheet metal in the recess to receive the door. But like Christy, this sheet metal panel is not incorporated in the car wall to take the stresses usually assumed by the bracing.

door is used that moves within'the plane of the car the diagonal compression or tension strut must be eliminated. theprior art no proper provision been -made to .take

care of these stresses usuallyassumed by the removed strut. p In order to maintain the capacity of the car or to increase the same according to the construction involving this invention, it is' i 40 necessary that the thickness of the car walls be decreased over that area over which the door moves. In order to provide a good substantial construction, it is necessary that the necessary decrease in the thickness of the i walls of the car should not decrease its strength and rigidity, andis capable of transmittingstresses between the sill and top plate.

According to this invention, a sheet metal panel of appropriate strength (and rigidity i is incorporated in the car wall in that area It will be evident that in cases when a flush over which the door lies when it is open. This sheet metal panel will impart the proper strengthand rigidity to the car wall and at the same time will allow the door to move within the outer plane of the sides of the car.

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

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

Figure 1 is a fragmentary side elevational view of a car involving this invention.

Figure 2 is a sectional view taken uponthe line IIII of Figure 1 lookingin the (direction of the arrows. I

Figure 3 is a broken horizontalsectional view of the construction shown in Figure 1 but upon a largerscale.

Figure 4 is a view similar to Figure 3 but illustrating a double sheathedcar.

Figure 75 is :a view similar to Figure 3 but illustratinga modification of a door post construction for a single sheathed car.

rFigure 6 is an enlarged and broken vertical sectional view taken upon the line VL- the rigidi-fyingmetal panel which forms the recess for containing the door whenthe -same has been moved :into its openposition.

, In referring to the drawings, it will be noted that acar door 1 has been illustrated as supported by rollers 2 traveling upon a track 3 which is secured to the slower sill'. The door is adapted to roll toward the right as shown in Figure '1.' In referringto ures 3 and 4'it will be noted that the front door vpost '8 which is made -of metal, is provided with an indenture 5 into which the front .end of the .door is ada, ted to extend for bringingthe door withint e plane of the outer surface of the car. It will be noted that the rear door post 9, which is also of metal, is in alignment with the indenture 5. The posts 8 and 9 preferably have wooden fillers 6 and 7 upon their inner sides.

In Figure 4-, which illustrates a double sheathed car, a slightly different form of metal post 8a is used at the front end of the door. The rear post 9, in Figure 4:, is substantially like the rear post shown in Figure 3. The rear posts 9 in both the single sheathed car as shown in Figure 3 and the double sheathed car as shown in Figure 4 have inwardly offset flanges 9a which extend longitudinally to provide means for attaching sheet metal panel 10. The panel 10 is' preferably corrugated in instances where a truss of the Howe type 1s used in connection wlth the car. The corrugatlons may however be dispensed with if a truss of the Pratt type is used in connection with the car.

It will be observed that post 9 extends a considerable distance around the rear side of the filler 7 in order to form a recess in the wall of the car where the panel 10 is located.

The rear edge of the panel 10 in Figure 3 is attached to a forwardly extending flange on an intermediatemetal post 11 having a filler block 12. In Figure 4 involving the double sheathed car, the panel 10 is also attached to a forwardly extending flange on an intermediate post 11a secured thereto.

The flanges on the posts 11 and 11a are in alignment with the attaching flanges9a on the rear door post.

The manner of attaching the upper edge of the panel 10 is best shown in Figures 7 and 8 and in referring to said figures it will be noted that a Z bar 13 has been attached to the side plate or Z bar 1d upon the inner side thereof and the upper edge of the panel 10 is riveted to the depending flange of said Z bar. The lower end of the panel 10 is secured to the upstanding flange of an angle bar 15 which is secured by means of a horizontal flange to the top of the side sill4. on

account-of the offset feature of the panel 10, certain eccentric stresses are produced and to overcome these, suitable reinforcing brack-v post 18 is substantially in the form of a T bar having a channel portion 18a for receiv ing the front end of the door. The rear door post 19 is also substantially in the form of a T bar having a wedge shaped projection 19a for cooperating with a weather strip upon the rear edge of the door. In this modified form, an intermediate post'21 having a filler 20 and which comes next to the rear door post is provided with longitudinally extending flanges in alignment with the flange of the T bar 19. The sheet metalpanel 10 is secured to the flanges of the post 21 and the T bar 19. In this modified form, a wood lining 22 covers the interior surface of the panel 10 so, that the interior of the car is substantially flush with the door post. While this wooden lining 22 reduces the width of the capacity of cars without bringing any part thereof within the line of tunnel clearances. The manner in which this is accomplished in" no way decreases the strength or rigidity of the car walls as has been the case in attempts heretofore. Moreover the struc- I ture whereby this result is attained is exceedingly simple and can'be easily applied to ex isting cars. 7

TVs are aware that many changes may be made and numerous details of construction maybe varied through a wide range without departing from the principles of this invention, and we do not therefore purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
