20 Claims. (01. 292-218) This invention relates to refrigerator car doors and is directed more particularly to swinging doors of the kind indicated and especially to the mechanism for forcing the doors into the door opening and for locking the doors in said position.

It is an object of this invention to provide mechanism for swinging refr erator car doors which shall substantially facilitate the positioning of said doors in their door openings.

A further object is to provide mechanism for swinging refrigerator car doors capable of easily seating the doors in their door openings, and with equal facility both from the ground and from platforms.

Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this specification:

embodying one form of the invention. Fig. 2 is a vertical section taken on line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken on line 3-4 of Fig. 1 and illustrating in dot and dash lines 25 the position of the lever when the door has been forced out of the door opening.

Fig.4isaviewsimilartoFig.3showingthe manner of automatically locking the lever when Door Company, Cleveillustrated in Figures 1 to 6, inclusive, the reference numeral l designates a portion of a side wall of a railway refrigerator car. As is customary, the side wall is formed with a door opening which is usually closed by a pair of swinging doors II and I2 respectively hinged as by means of hinges Iii-J3 and H-ll to the side wall of the car. The meeting edges of the doors are sloped, as clearly shown in Fig. 5, and so related that the edge of the right hand door [2 overlaps the edge of left hand door I I. The Joint between the meeting edges of the doors is weatherstripped by means of the well known spring-pressed La Flare packing l5 which, as shown, is carried by door l2. The top and hinged edges of the doors are similarly weatherstripped, as shownin Figs. 2 and 5. The lower portion of each of the doors is weatherstripped by means of the compressible strips l6 and I1, as more clearly shown in Fig. 2 of the drawings.

A vertical bar It, shown in the form of a pipe is mounted upon door I2 for rotation about its axis by means of a plurality of bearings I9, and 2|. The ends of bar II are provided with cranks 22 and 23 which are adapted to enter and leave keepers 24 and fastened to the car side above and below the door opening. and to cooperate therewith to force the doors into and out of the door opening. As will be readily apparent,

the door has been forced into the door opening. the movement of the doors into the door opening Fig. 5 is a horizontal section taken on line 5-8 of Fig. 1.

Fig. 6 is a view similar to Fig. 5 showing the association and operation of the mechanism when the door is forced out of the door opening.

Fig. 7 is an elevation of a pair of swinging refrigerator car doors equipped with mechanism embodying another form of the instant invention. Fig. 8 is a horizontal section taken on line H of Fig. 7.

Fig. 9 is a view similar to Fig. 8 showing the position of the mechanism after the door to which it is applied has been partly opened.

Fig. 10 is a vertical section taken on line lll0 of Fig. 7.

. Fig. 11 is a vertical section taken on line I l of Fig. 7.

Fig. 12 is a vertical section taken on line i2-l 2 of Fig. 7.

. Referring first to the form of the invention 50 explained. I

so as to lie flush with the car side must be accomplished against the substantial resistance oifered by the plurality of springs of the La Flare packing and the weatherstrips l6 and ll.

8' To this end a clevis 26 is fastened upon bar l8,

as by means of welding, so as to rotate therewith. A lever 21 is pivotally secured for vertical swinging movement within the jaw 28 formed on the collar by means of a pin 29. The free end 40 of the lever is preferably reduced in width as 4 a pin 34 whose ends are supported in the vertical walls 35 and 36 of said portion. A vertical lever 31 is suspended from pin 34 so as to permit the free end of lever 21 to be received within an opening 38 in lever 31 for the purpose hereinafter pressed toward door When the doors are open lever 21 will be suspended vertically from pin 29 on the right of bar 3 and vertical lever 31 will be suspended from pin 34. In the closing operation door II will be swung around its hinges |3|3 into the door opening until the hinged edge thereof contacts the adjacent La Flare packing. The pivoted stop 39 is then raised across the lower edge of door I I so that it cannot accidentally swing open. Door I2 is then swung about hinges |4|4 into the door opening until the hinged edge thereof contacts the adjacent La Flare packing and its free edge overlaps the free edge of door I I. Lever 21 is then raised to a horizontal position and swung toward door thereby rotating bar 8 about its axis and causing the ends of crank; 22 and 23 to enter the keepers 24 and 25. Lever 21 may then be supported upon a ledge 40 preferably formed integral with hearing 20.

To complete the closing movement of both doors with ease the reduced end of lever 21 is passed thru opening 38 in lever 31 which is then In this manner a far greater leverage is exerted upon bar l8 and cranks 22 and 23 than could be exerted by a force applied by hand directly to the end of lever 21, and doors II and I2 are easily closed against the resistance offered by the weatherstrips through the cooperation of the cranks and their keepers.

By pulling lever 31 away from door I I when the doors are closed a similar large leverage acting thru the cranks and their keepers easily forces door l2 from the door opening and permits full opening of both doors.

To maintain the doors in closed position against the pressure of the weatherstrips automatic locking means is provided. In the form shown, the locking means embodies a bracket 4| secured in a recess 42 in door so as to lie flush therewith. A vertically disposed catch 43 is pivotally mounted in bracket 4| and projects outwardly therefrom. Downward movement of the catch is limited by a lug 44 formed on the pivoted end of the catch which contacts the bracket for this purpose as shown in Fig. 3. The outer end of the catch is rounded as shown at 45 so that the catch will automatically be raised when this end is engaged by a pin 46 formed on lever 31.

Thus, after the end of lever 21 is received in opening 38 of lever 31 in the closing movement of the doors and lever 31 is pressed toward door pin 46 will toward the end of this movement engage the rounded end 45 of catch 43 and raise the latter so that it can engage over pin 45 and lock lever 31. The doors are now securely held in closed position. A seal (not shown) may then be threaded thru alined openings 41, 48 and 49 formed in the catch, lever and bracket 4|, respectively.

In the form of the invention shown in Figs. 7-12, inclusive, a collar 50 is rigidly secured to bar |8, as by means of welding. Integral with the collar are an arm and a shorter arm 52 spaced from arm 5|. A lever 53 is pivoted intermediate its ends upon a boss 54 integral with arm 5| and is retained thereon by means of a rivet 55 passing thru the arm, boss and lever and by a washer 56. The opening in the lever thru which the boss passes is larger than the boss and the clearance thus provided together with the upward and rearward slope 51 of the arm above the boss permits lever 53 to be tipped in a plane substantially at right angles to arm 5| as shown in Fig. 10.

When the doors are open lever 53 is suspended vertically from arm 5| at the right of bar II. To close the doors after they have been swung into overlapping relationship, as hereinbefore explained, lever 53 is swung to the horizontal position shown in dot and dash lines in Fig. 8 of the drawings so that the upper end thereof is received between the arms 5| and 52. The lever is then swung toward door so as to rotate bar II and cause the ends of cranks 22 and 23 to enter keepers 24 and 25. Lever 53 is then swimg to the vertical position and tipped so that the upper end may be swung under bracket 58 secured to door |2. With bracket 58 serving as a fulcrum a force is applied to the lower end of the lever and through it to the outer end of arm 5|. These forces produce axial rotation of bar l5 in the brackets I9, 20 and 2| and rotation of the cranks 22 and 23, which by their engagement with the keepers 24 and 25 force the doors into the door opening against the resistance of the weatherstrips.

Door l2 may be forced from the door opening through the coaction of the cranks and keepers by pulling the lower end of lever 53 outwardly so as to impart rotation to bar l8 in the opposite direction. Lever 53 is then swung to a horizontal position between arms 5| and 52 and counterclockwise to release the cranks from the keepers so that the door may be fully opened. Door may then be opened readily.

The operation of lever 53 to force the doors to closed position is utilized to lock the doors in said position. For this purpose lever 53 is formed with an opening 59 and a rounded portion 50 at,

the lower edge of the opening, and is adapted to cooperate with bracket 4| and catch 43, heretofore described, to automatically lock the doors in closed position. During the movement of lever 53 toward the door the rounded portion 50 will contact the rounded outer end 45 of the catch and raise the catch. As the movement of the lever continues the catch is projected through the opening 59 in the lever and drops over the rounded portion 60 thereby locking the lever and the doors. A seal (not shown) is then threaded opening 41 in the catch and alined opening 55 and 6| formed in lever 53.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such changes and modifications be comprehended within this invention, which is to be limited only by the scope of the claims appended hereto.
