FOREIGN PATENTS OR APPLICATIONS 696,812 9/1940 Germany ..49/2l6 Primary Examiner-Kenneth Downey Attorney-Bede" and Burgess [57] ABSTRACT Door operating mechanism particularly adapted for railway house car sliding doors of heavy plug type which are shifted transversely of the wall out of the door opening before movement alongside the car wall and are shifted transversely of the wall into the door opening after movement along the wall from open position to a position abreast of the opening. The mechanism includes means automatically holding the door spaced from the car wall when the door is being moved along the wall, but freely accomodating shifting of the door transversely of the wall out of and into the door opening when the door is opposite the wall opening.
5 Claim, 5 Drawing figures Patented Aug. 15, 1972 yfnnun PLUG DOOR CONTROL MECHANISM The door and operating mechanism is of the general type described in U.S. Pat. No. 3,468,062 in which the door is mounted on carriages traveling on a track alongside a wall and an elongated rack extends from the rear edge of the door and is engaged by a manually operated gear and pinion for moving the door along the track to positions abreast of or spaced from an opening in the wall.
In railway car plug doors, as here described, there are crank arms pivoted on the carriages for movement of the door transversely of the wall inwardly and outwardly of the opening. In my copending application filed Apr. 27, I970, Ser. No. 32,409, a locking pin or latch has been manipulated manually to hold the door spaced outwardly from the wall during movement along the wall. The present invention obtains the same result automatically by utilizing an arm pivoted at one end to the rack and having a double pin and slot connection near its other end to the door.
The main object of the invention is to obtain such automatic locking and to avoid the necessity of ,a workman keeping in mind the importance of maintaining the door spaced from the wall, and thereby eliminate scraping of the wall by the sliding door.
In the accompanying drawings illustrating a selected embodiment of the invention,
FIG. 1 is a side elevation of one longitudinal half of a railway house car with a door opening in its side wall and a plug door shiftable transversely of the wall into and out of the opening and movable lengthwise of the wall to a position spaced from the opening.
FIG. 2 is a large scale horizontal section on line 2--2 of FIG. 1 showing the door in fully closed position.
FIG. 3 is a similar section showing the door shifted transversely of the wall and out of the opening in the wall.
FIG. 4 illustrates the pivoting of the arm into a position in which it and the rack form a rigid pull and thrust unit.
FIG. 5 is a detail vertical section on line 5-5 of FIG.
The car body includes an underframe l, and a side wall 3 having the usual door opening normally closed by a door 5. A track 7 on the underframe mounts wheeled carriages 9. Upright shafts 11 have cranks 12 with outer ends journaled in carriages 9. The shafts are journaled on and support the door. Mechanism M including rotatable handles 14 on a threaded nut, and elongated levers 15 provide for manually shifting the door transversely of the wall between the FIG. 2 and FIG. 3 positions. All of the above structure is well known.
A rack bar alongside the wall has openings engaged by the teeth of a gear wheel 22, journaled on the wall and rotatable by a handwheel 23, to feed the rack bar toward and away from the door opening. A link arm has a pivot 26 at one end to rack bar 20, to swing transversely of the bar, and near its other end has two slots 28, 29 receiving studs 31, 32 respectively, fixed in the horizontal flanges 34 of angle brackets 35 on the door.,
Each slot 28, 29 is elongated with rounded ends and has a rounded notch 38, 39 respectively, intermediate its ends. Notch 38 in slot 28 faces in a general direction towards the outer edge of arm 25 (FIG. 2) and notch 39 in slot 29 faces generally in the opposite direction toward the inner edge of arm 25. When the door is in fully closed position (FIG. 2) the studs are at the right hand ends of the slots. When mechanism M is actuated to shift the door outwardly of the opening to the position shown in FIG. 3, arm 25 swings anti-clockwise about pivot 26, and stud 32 and a torsion spring 41 thrusts the arm in the direction of arrow A causing notches 38, 39 to engage the studs.
Upon operation of wheel 23 in a clockwise direction, rack 20 and arm 25 move to the right to the FIG. 4 position and the studs are in the extreme left hand ends of the slots and lock arm 25 against pivoting relative to the door by further movement of the rack bar to the right and, upon continued rotation of wheel 23 clockwise, the rack and arm are a rigid pull unit and there is no tendency to thrust the door against wall 3 during its movement to full open position.
To close the door, hand wheel 22 is rotated in anticlockwise direction and arm 25 slides to the left on studs, 31, 32, until the arm and studs are again in the FIG. 3 position and the rack and arm form a rigid push unit. Continued rotation of wheel 23 moves the door to the left until it is in front of the opening, and its left hand carriage 12 engages a suitable stop on track 7. Then mechanism M is actuated to shift the door transversely into the wall opening to the position shown in FIGS. 1 and 2.
Throughout movement of the door lengthwise of the wall it is maintained spaced from the wall whether moving away from the opening or towards the opening. Movement transversely of the wall is only effected when mechanism M is actuated by handles 14 and levers 15.
The specific contours of slots 28, 29 are illustrative only and variations in their shapes and in other details may be made without departing from the spirit of the invention which avoids the necessity of manually locking the offset rack bar and connecting arm to effect a straight pull and thrust on the door by manipulating a locking pin as shown at 21 in the earlier application mentioned above.
