3 Claims. (011258-44) This invention relates to railway car side doors and more particularlyto means for moving such doors. The conventional box car has a door opening adjacent the center o f'each side wall and doors movable in planes parallel with the side walls for closing the door openings. i

An object of the invention is to provide rolling means for railway car side doors, which means may be easily brought into operative engagement with the track by movement'of a conveniently located handle. A further object is to utilize such handle to engage bracket carried by the track for the purpose of imparting initial. movement tothedoor. i

Another object is to provide wedge shaped engaging parts on the door andvtracks, respectively, e to support the door when the rolling means are disengaged from the track. 'I'he'wedge provides additional friction to retard movement of the door.

Another object is to provide toggle means for lifting the door and bringing therolling means into engagement with the track. It is well known that a toggle is well suited for lifting heavy ob-' jects; such as railway car doors.

Otherobjects and advantages of my invention will be apparent from the 'following detailed description by referring to the ings.

In the drawings:

tached to thetrack 3. The lower end 25 of the lever 22 may be engaged with the blocks 23, as

shownin the drawings, to impart initial movement to the door. Connecting members 26, 21 extend. from the lever 22 to the center joints l3 of each of the toggles 8. Movement of. the upper end 28 of the lever 22 toward the right straightens both toggles 8 and moves the rollers l4 downwardly into operative engagement with the track 3, as shown in Fig.4, so that the door is then movable upon the rollers Id. The door may then be moved to thefull open position by exerting a force upon' the lever22 in the required direction; i. e., toward the right. i p t .A stop 29 is preferably provided on the connecting member 26 within the housing 5 to limit move- .ment of the connecting member 26 and thereby limit the downward movement of'the roller [4.

The track 3 is comprised of an angle with the inwardly directed leg 32 flared (33) downwardly: and inwardly. The housings 5, 6 are provided with pads 35 adapted to engage the flared part 33 of the track 3 and thereby support the door 2 when th lever 22 i released and the rollers l4 move upwardly out of operative'engagement withthe track. The pads 35 cooperate with the depending outer sides 36 of the housings 5, 6 to straddle and wedge uponthe track 3 and thereby frictionally retard movement of the door.
