View corresponding 's flbgtantial ly to i zhe hne shQWIi; as prd- 70f cally slotted to receive the corresponding end of the shaft A, to which it is riveted. The

- casting B, which is secured to the lower end of the shaft A, is of greater lengththan the casting B at the upper endof the shaft and has an arm 17' laterally projecting therefrom to whicheis pivotedthe operating handle. or lever C, the arm 17 being so disposed as to project nearly diametrically opposite to the crank portion 15.

' The bearing brackets EE which of like construction are secured to the door 12 form of a-casting having an outwardly oftset central 'portion;19 provided with-a slot or double'acting camgroove 20. The lower ;-keeper -D is-mountedon the door 11 adjacent the free edge'ther'eof, being so'disprosed :and the upper keeper D is mounted on the 5 as to cooperate withthe lower crank'arm door frame immediately above -thecdoor 11, being so :disposed as to cooperate with; the upper-.crankarm15.

' Thedoor first closed 'is the retain the same in closed position while the "door operatingmechanism is manipulated, a

dthotrg h'the same :is not absolutely essential in that the operating mechanism will proper- -ly perform'its function with the latchjmember 'F omitted.

The handle C is adaptedto-be locked as vl'rshowninFigure 1, by any suitable locking 7 -Qdeviceyasindicatedat 22and sealed inyany 'rsuititble manner, customary onrailr'oad-cars. In operating my invention, thedoorll Wlll ifirst'zbe movedito closed: position and secured 7 byjthelatchFQffhe'door 12is then swung inwardly, the shaft 'A being first movedto ";iopposite ends of the sameiwill be disposed in gsuch a position that the crank arms 15at the az plane substantially at right anglesto the l plane' of thefdoori NVhilet'hedoor 1'2 is'ibe 1 A iirg moved toward closed position, the 'cran'k farms 15 enter the "slots -20. After the crank door 11,.and to arms 15 have been engaged within the slots,

the shaft A is rotated by swingingthe handle C to the right to the position shown in'Figure 1. Upon rotation of the shaft A, them'embers 15 will be guided by the keepers D and the door 12 forced to tightly closed position bythe crank acting oifsetoportions 15. The handle C is then locked to the device 22 and sealedin the usual manner. 7 p p Y To open the door 12, thehandle G is swung outwardly away from the dooras seen in Figure 1, thereby rotating the'shaft A in the reverse direction to thatjust described. Rotation of the shaft A is continued until the members 15 clear the slots 20, during which action the -crankp ortions 15 of-the end castings B in cooperation with the grooves 20, of the keepers will have forced the doors 11 and '12 partially apart, whereupon the door 12 maybe swung fully open. Upon releasing the handle C, the same-will drop out of the V waytothe dotted line position indicated in Figure 1.

From the preceding description taken in connection withthe drawing, it will be evident that I have provided a very simple and efficient door operating mechanism, which entirely overcomes the defects encountered in prior devices of'this character, in that the operating shaft extends beyondthe top edge of the door only and hasthe'lower end thereof terminating short of the bottom of the door. a r 7.

It will be evident that my improved'door operating-mechanism isadapted to be appliedto doors of differentdimensions varying in height, without making any changein the dimensions of the operating mechanism. In other words, due to the fact that the distance between the upper and lower keepers does not; ;in any way depend on the height; of the door, but depends directly on ,the length of the operating shaft, the. ,door operating mechanism may be 'standardizedso that a single size will suficefor all heights of,doors,-thusmaterially reducing manufacturing costs.

I have herein shown and described wh at I now consider the preferred manner of carry ing outmy invention but the same is merely illustrative and I contemplateall changes andmodificatlons that come within the scope of the claims appended hereto. ;Iicl aim: I 1
