Additionally, the door l2 and the movable section 24 are substantially flush with the outer plane of the side wall 22 of the car. It is to be observed, moreover, that the combined depths of the stationary wallsection 23 and the movable wall section 24 is sub-.

stantially the same as the depth of the remainder of the side wall 22.

The'side wall'22 is preferably formed of a plurality of pan-sh aped panels 25 provided with inwardly extending flanges 26 and 21 positioned in abutting relationship and secured together preferably by means of welding. The panel adjacent the forward edge of'the door I2 is provided with an inwardly and forwardly inclined portion28 adapted to engage a correspondingly inclined portion29 formed at the forward'edge of the door. The panel 25 at the rear edge of the movable section 24 is provided with an inwardly and rearwardly inclined portion 30, adapted to overlie a correspondingly inclined portion at the rear margin 3| of the movable section. Similarly inclined portions 32 and 33 are provided on the rear margin and on the forward margin of the door and movable section, respectively.

v The car Ill embodies in its construction, a plurality of side sills. Aside sill 34 is clearly illustrated in Figures 5 and 6 of the drawings and projects outwardly beyond the door opening 2| and the stationary section 23 of the car, the outer plane of said side sill lying substantially flush with the outer plane of the side wall of the car. Referring again to Figure5 of the drawings it will be observed that the projecting portion at the side sill serves as a track upon which the door, l2 is adapted to slide-in. its travel toward open and closed positions. In the normal or closed position of the door [2 and the movable section 24,,said section as well as the door overlie the projecting portion of the sill. Moreover, in the'normal position of the door and the movable section the engagement therebetween prevents travel of the door toward open position. To .permit such travel of the" door the movable section must bedisplaced relative to the projecting portion of. the sill which it overlies.

To this end the movable section at its rear margin is supported upon the side wall of the car by means of the plurality of hinges l1. These hinges as clearly shown in Figures 2 and 3 of the drawings, are preferably of the multiple pintle type, each comprising a strap portion 35 secured to the movable section, a strap portion 38 secured to the panel 25 and links 31 secured at the respective ends thereof to the strap portions 35 and 36 by means of the pintles 38 and 39. It will be observed that the hinges I! permit both lateral and longitudinal movement of the rear margin of the section.

The. actuating means I6 is utilized adjacent the forward margin of the movable sectionfor actuating said section to effect lateral and longitudinal movement thereof. This means, in the present embodiment of the invention, employs a vertical bar 40 rotatably secured to the section by means of a plurality of brackets 4|. The ends of said bar are provided with cranks 42 and 43, the ends 44 and 45 of which are rotatably secured to the car by means of brackets 46 and 41. A lever 48 is secured to the bar in order to effect rotation thereof, said lever being adapted to be secured to said section by any desired fastening means, such as shown generally at 49.

It will be apparent that upon release of the lever 48 from the fastening means 49 and swinging of said lever tofthe left as viewed in Figure 1 of the drawings rotation will be imparted to the bar which will impart a lateral movement and a longitudinal movement to the forward edge of the movable section. These movements will also occur at the rear edge of said section because of f the construction of the hinges H. The movable section upon operation of the actuating mechanism l6 wfll finally assumethe position shown in Figure 3 of the drawings. The outward position'of the section 24 as shown in said figure will i expose the projecting portion of the side sill 34, heretofore covered by said section. Either of the handles l8 and I9 may then be grasped and the door l2 moved upon the side sill to its open position. and I9 will lie forwardly of the movable section so that the door may readily be returned to its closed position. Movement of the door to its closed position and operation of the actuating mechanism in the reverse direction will restore the door and the movable section to their normal or closed positions, as clearly shown in Figure 2 of the drawings. The forward edge ofthe door will be maintained in sealing engagement with the adjacent panel of the car and the rear edge of the movable section 24 will be maintained against'outward movement by the overlying portion 30 of the panel 25. As the movable section is actuated to its normal or closed position the portion 33 of the forward edge thereof will engagethe portion 32 at the rear edge'of the door and exert a longitudinal thrust to said door to insure positioning of the door in its fully closed position. This overlapping will additionallyproduce an inward pressure upon the door so as to cause it to seat sealing engagement between the section and the 5 adjacent portion of the door. To complete sealing engagement around the four edges of the door the top and bottom thereof are provided. respectively, with plates 50 and 5| adapted to engage the adjacent portions of the car. A substantially Z-shaped member 52 secured preferably by welding to the car overlaps the plate portion 50 secured'to the upper horizontal margin of the door, enhancing the weatherproofing qualities at said' margin of the door and serving additionally as a guide andretainer therefor in its opening and closing movement. j At its lower margin the door is guided and retained against In said position of the door the handles l8 disengagement from'the track by means of the projection of the hinges "for the purpose of dec'reasi'nghthe' airpre'sistance upon-the car in transit..

I The door) Mamas on. metamf pane-1 51 and is. provided preferably with a wooden frame 58; The movable section 24 comprises a metallic panel =59'and isprovided with vertical. framing members 60 and 6!, preferably constructed of wood; "The framing member 60 of the movable section; because of the engagement between said section andthe door-l2 serves as a-jamb for the door. The invention as applied, to a refrigerator car is illustrated in. Figures '7 to ll; inclusive, of. the drawings. as formed :of wood andis provided with the customary insulating material 63. As in .the previous embodiment of the invention the car 52 is provided-with .a door opening 64 adapted to beclosed by meansgof a straight sliding door 65, also formed .of wood, and provided with the in,- sulating material 63.; Adjacent the door opening the side; wall 660i the-car is formed of a stationary section 61 and a. laterally nioyablesection 68. xTheengagement between thedoor and the laterally movable-section and the engagement between saiddoor and. its adjacentfixed jamb andbetweenthe movable section and the adjacent wall remains the same as that in the heretofore described embodiment of the invention. The movable section .68 is provided with a clearly shown in Figure. 10 of the drawings, a

portionlof the door lies within the outerplane of the, car. A threshold plate 14 is. securedadjacent the side sill and a plate 15 is secured to the car abovetheinwardly projecting portion of the door.

. These plates are provided with vertically'aligned I indentations l6- and I1, respectivelyu The lower margin of the inwardly projectingpor'tionof the door isr'ecessedas indicated-atl'lB and is adapted to ,rpceive brackets 19 provided with vertical rollers 88,.

A weather stripfiiis secured at one end to. the inner face of the inwardlyprojecting portion of they door and at its other end to the outer face of the filler 84. The weather strip 85 is continuous for the'entire width of the door. The upper margin of the inwardly projecting portion of the door'is-similarly formed; the. parts thereof being reversely arrangedjirom the corresponding parts described for the lower margin of the inwardly. projecting portion. 1 1 1 Y 1 It willbe'a'pparent from the foregoing description ofyth'e construction and partsjof: the upper and lower 'portionsiof, the. inwardly projecting part the. depressions 16 and'l'l.

The refrigeratorcar 62 is illustrated 3 or the doorthat when the door is in its fully closed position the rollers at will be seated within The seating of the rollers in the portions .16 and-Tl will be aided by the: springs 8i. In this position of the rollers the filler blocks 84 will engage the weather strips SS-at the-top and bottom of the door and, under the influence of thesprings, force the sealing strips into tight engagement with the plates M and 15, forming a tight seal at the upper and lower portions of the. inwardly projecting part of thedoor; .When the door is moved toward open position the rollers 833 will ride out of the de pressed portions 16 and Hand, together with the roller brackets and wooden fillers, be forced against the tension of the springstl further'into the recesses 18. In consequence of this movement the weather strips 85 will be retracted and will be maintained by the rollers out of engagement with the plates M and E5 was to prevent wear on said weather strips. l V ,It is manifest fromthe foregoing that sealing constructions are provided around the four edges of the door and,.also, that by Virtue of the weatherproofing'strips secured to the'upper, lower-and rear edges ofthe movable section such section also maintains sealing arrangements around its perimeter. l 1:
