Intermediate the bearing member 63 and the cylinder 59 the piston rod 61 is preferably provided with an enlarged portion 64:, with which an arm 65 secured to the transverse shaft 30, is operatively connected by a pin 66, or other suitable means, which preterably passes through openings formed in the arm 65, and the enlarged portion 64: of the piston rod. It will be noted that when the door operating mechanism is being operated, the arm '65 moves in van arc of a circle and the piston rod 61 moves in a straight line, thus making it necessary to provide a loose connection between the arm and piston rod to insure the free operation of the mechanism. The object may be attained in a number of ways but in the present embodimentof the invention is preferably attained by making the opening in the piston rod of slotted form havinga width greater than the diameter or the pin 66, which passes therethrough and a length great enough to permit of the maximum movement of the arm 65,
The motor 58 is arranged to operate at an angle to the motor 57, and comprises a cylinder 87 which is secured to the plate 7 or any other suitable part of the car, and also comprises piston 68 and piston rod 69, such piston being secured to one end of the piston rod and arranged to reciprocate in the cylinder. The opposite or outer end portion it) of this piston rod is preferably of rectangular form and preferably extends to the piston rod 61, and as indicated at 71 menses .7 2 registers with the opening 62 of the bearing member 63, thus permitting the end portion of the piston rod 61 .to pass through the outer end ortion of the piston rod 69 and throng the bearing member 63. For
the purpose of operating the piston rod 69 by hand power a ivoted lever 73 is provided, one arm which extends to the side of the car where it may be easily operated when it is desired to operate the whole mechanism by use of the shaft 54:. The other arm of this lever is connected with one end of a link '74, the opposite end of such link being loosely connected with the piston rod 69, such connection being preferably made by bending the end portion of the link 74 in the form of a hook which extends through a slot 7 5 formed in the outer end portion of the piston rod 69.
76 indicates a pressure supply pipe which extends preferably from end to end of the car and may be provided with cocks 77. Between these cocks and at each end of the car this supply pipe is provided with a branch pipe 78 which is connectedwith a port 79 formed in the cylinder 67. Some distance from-the port 79 the cylinder is provided with a ort 80 which is connected with a port 81, formed in the cylinder 59,
by a pipe 82. This cylinder 6'? is also provided with an outlet 83 to the atmosphere, the use of which will hereinafter be described. 8 l indicates another pressure supply pipe which extends preferably from end to end of the car and may beprovided with cocks 85. Between these cocks and at each end of the car, the supply pipe 8% is' provided with a branch pipe 86 which is connected with a port 87 formed in the cylind pr 59. p
When it is desired to automatically open the discharge doors one of the cocks 77 is closed and a pipe or hose from the fluid pressure supply is attached to the other cock 7 which is open. Fluid pressure is then introduced which enters the cylinder 67 through the supply pipe 7 6 and branch pipe 78 and moves the piston 68 and piston rod 69 a suihcient distance to slide the opening 72 in the portion 70 into registration with the opening 62 in the bearing member 63. Immediately after the openinglfl has registered with the opening 62, the piston 68 This rectangular portion 70 of.
passes the port 80, permitting'the pressure to enter the cylinder 59 through the pipe 82, and move the piston 60 in the direction indicated by the arrows in Fig. 4: of the drawings a sufficient distance to fully operate the door operating mechanism. When the piston 60 is being moved in this direction by the fluid pressure, the air in the cylinder on the other side of the piston is allowed to escape to the atmosphere through the pipes 86 and 84. Between the port 80 and the outlet 83, the cylinder 67 is provided with a portion 88 which forms a stop for the piston 68 when such piston has passed the port 80, thus preventing the piston from passing the outlet 83 and the escape of the pressure through such outlet.
When the piston 60 is moved in the direction referred to above, the end portion of the arm 65 is moved in the same direction through the intervention of the piston rod, which connects the piston and arm, with the result that the arms 33, 33, which are secured to the shaft 30, are caused to move in the opposite direction, and through the medium of the links 35, 35 cause the bell cranks 38 to raise the links 4A, 44-. These links 44, 4A are connected with the toggle mechanism 46, 46 and when they are raised by the bell cranks 38, they will move the links of the toggle mechanisms and the discharge doors to the posit-ions as shown in dot and dash lines in Fig. 3 of the drawings.
When it is desired to automatically close the doors, one of the cocks is closed and a pipe or hose from the fluid pressure supply is attached to the other cook 85 which is open. Fluid pressure is then introduced through the supply pipe 84 and branch pipe 86 to the cylinder 59, which forces the piston 60 in a direction opposite to that indicated by the arrows in Fig. a of the drawings, the air on the other side of the piston being permitted to escape to the atmosphere through the pipe 82 and outlet 83 in the cylinder 67. The operation of the rest of the mechanism. when the doors are being closed, is the reverse of thatv just described in connection with the opening of the doors.
Within the cylinder 67, a spring 89 is provided which when the doors are being opened will, by the movement of the piston 68, be compressed, and which when the doors are being closed, will expand and force the piston 68 and piston rod 69 to their normal positions of rest, as shown in full lines in Figs. 5 and 6 respectively.- When the doors are being opened by the use of fluid pressure the piston 68 moves forward until it engages the stop 88 in the cylinder at which time the portion '26 of the piston rod 69 is in the position as shown in dot and dash lines in 6, the piston and piston rod remain "ing in such positions until the doors have been opened. After the doors-have been opened and the fluid pressure shut off, the spring 89 will force the piston 68 backward beyond the port 80 to a position, as shown in dotted lines in Fig. 5, thus permitting the exhaust pressure from the cylinder 59 when the doors are'being closed, to escape to the atmosphere, through the outlet 83, the slot 72 in the piston rod 69 being of a length great enough to permit such movement of the piston 68 relative to the port 80. When the doors are closed and when the end of the piston 60 has been drawn from the opening 72 in the piston rod 69, the spring 89 will force the piston 68 backward to its normal position of rest, as shown in full lines in Fig. 5, and will thus move a portion of the piston rod 69 across the opening 62 in the bracket member '63, which will prevent accidental movement of the piston rod 61 and will thus lock the mechanism against accidental operation.
When it is desired to operate the mechanism by hand power, the operator moves the lever 73 in the direction as indicated by the arrow in Fig. & and such lever being pivoted as indicated at 90 will cause the portion 70 of the piston rod 69 to move a sufficient distance to unlock the mechanism, the maximum movement of the piston being shown in dotted lines in Fig. 5. The shaft 54 is then rotated in the direction as indicated by the curved arrow in Fig. 2 and the gear wheel 55 mounted on this shaft meshing with the toothed quadrant 56 mounted on the shaft 30, will cause the mechanism to operate in the same manner as hereinbefore described. It will here be noted that by reason of the loose connection between the lever 73 and the portion 70 of the piston 69, the piston when it is being operated by fluid pressure will be permitted to move independently of the lever 7 3, thus rendering the fluid pressure unlocking mechanism entirely automatic.
It will be seen from the foregoing description of the mechanism that the doors of a train of cars may be operated automatically and substantially simultaneously. By connecting the cocks 77 and 77 of adjacent cars, closing one of the cooks 77 at one end of the train, and then admitting pressure through the other cock at the opposite end of the train, the operation of the mechanism as hereinbefore described in connection with a single car, will be repeated throughout the train of cars, and the doors of all the cars will be opened simultaneously or nearly so.
By connecting the cocks 85 and 85 of adjacent cars, closingone of the cooks 85 at one end of the train and then admitting pressure through the other cock 85 at the opposite end of the train, the operation of the mechanism will be repeated throughoutthe train of cars and the doors of all the cars will be closed simultaneously or nearly so. In operating remaining cars of the train.
menace a train of coupled cars embodying the invention, it may be desired to discharge the lad ing from certain of the cars and to leave the remaining cars of the train loaded so that they can be moved and discharged at some other place. In order to do this the branch pipes 78 of each car areprovided with cocks 91 by means of which the fluid pressure supply maybe shut ofi from the discharge door operating mechanisms of the car or cars that itis not desired to discharge. By this means'it is possible to discharge the load from any one car or serie of cars in a train and at the same time retain the load in the The branch pipes 86 of each car is provided with cocks 92 by means of which the fluid pressure may be shut off from the discharge .door operating mechanism of a car or cars that it is not desired to close the doors. The car as hereinbefore described is provided with two pairs of doors which are operated by two pairs of motors, one pair of motors being for one pair of doors. It may be found desirable to discharge only a portion of the contents of the. car, and to do this, one of the cocks 91 is closed and the other one opened, thus permitting one pair of motors to operate to open one pair of doors only. When a, plurality of cars, embodying the invention, are coupled together, it will be noted, the whole contents of some of the cars may be discharged and that only a portion of the contents of other cars may be discharged, while the contents of the remaining cars may be retained and discharged at some other places.
From the foregoing description it will be apparent that changes may be made in the arrangement and construction of the parts of the mechanism without departing from the spirit and scope of the appended claims.
