INTERLOCK MECHANISM.
Application filed September 29, 1922.
This invention relates to interlock devices, and more particularly to a mechanism for interlocking the operation of an electric switch with the operation of a fluid pressure controllin cock.
When e ectric train line circuits are employed on cars of a train, it is sometimes desirable to provide a manually operable switch on the cars for opening and closing the train line circuits independently of the electric train line couplers between the cars, as, for example, in the case of cars equipped for multiple unit control and where the electric train line couplers are of the type in which the circuits are opened by the separation of the cars. In such case, when power is applied to one car, power is also supplied to the other cars, so that even if cars are uncoupled, they may not be separated, as
all cars will be moved simultaneously by power applied to each car.
In order to ensure the proper operation of a switch of the above character, the principal object of my invention is to provide ll an interlock between the fluid pressure pipe cut-out cocks and the switch such that t e switch must be moved to open position before the cut-out cocks can be moved to closed position and the cut-out cocks must be moved so to open position before the switch can be moved to closed position.
In the accompanying drawing; Fig. 1 is a diagrammatic view of an interlock mechanism embodying my invention, showin the 8 parts in position with the switch close and the cut-out cocks open; Fig. 2 a similar view, showing the parts in position with the switch opened and the cut-out cocks open; and Fig. 3 a similar view, showing the parts U in position with the switch opened and the cut-out cocks closed.
In the drawing, the reference numeral 1 indicates a switch device for controlling the opening and closing of electric train line I circuits and having an operating lever 2 and the reference numeral 3 indicates one or more fluid pressure train line cut-out cocks, each having an operating lever 4. A lever operating bar 5 is provided, having elonted slots 6 for receiving supporting pins carried by the car framing (not shown).
Said bar 5 is positioned in alinement with the ends of the levers 2 and 4 and is pro Serial No. 591,351.
vided with staggered pins 8 and 9 adapted to engage vthelever 2 according to the direction in which the bar 5 is moved. The bar is also provided with two sets of staggered pins 10 and 11 for engaging each of the levers 4 according to the direction of movement of the bar 5. For operating the bar 5 a pivotally mounted rocker arm 12 is provided, having a pivotal connection to said bar and having connected thereto oppositely extending operating rods 13 b which the bar 5 may be operated from either side of the car.
In Fig. 1, the parts are shown in the normal position for running, with the electric train line switch 1 closed and the cut-out cocks 3 open. If it is desired to uncouple and separate a car from the train, one of the rods 13 is pulled outwardly and thereby the bar 5 is moved toward the left. The pin 9 engages the lever 2 upon the initial movement of the bar 5 and the lever 2 is thereupon shifted to the position shown in Fig. 2, in which the train line circuits are opened by the movement of the switch. The cut-out cocks 3 are still open, but u on a further outward movement of one o the rods 13, the pins 11 will each engage a corresponding lever 4 and then the lever 4 will be shifted to the position shown in Fig. 3, in which the cut-out cocks 3 are in the closed position.
When a car is coupled to another car, one of the rods 13 is moved inwardly, so as to shift the bar 5 toward the right of the position shown in Fig. 3. The initial movement of the bar 5 then causes the pins 10 to each engage the corresponding lever 4 so that the levers are moved to the cock open position as shown in Fig. 2, the switch lever 2 not having been moved. Continued movement of the bar 5 to the right after the cut-out cocks have been turned to their open positions, causes the pin 8 to engage the lever 2, thus effecting the movement of the switch to the closed position, so that the parts are now in the running position, as shown in Fig. 1.
By means of the above described construction, it will be seen that the switch must be moved from the closed to the open position before the cut-out cocks can be moved to the closed position and that the cut-out cocks must be moved from the closed posi tion to the open position before the switch can be moved to its closed position.
Having now described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A cock and switch operating mechanism comprising a cock operating lever, a switch operating lever, a sliding bar, means on said bar for engaging and moving said levers upon a sliding movement of said bar in one direction, and manuall; operable means for shifting said bar.
2. A cock and switch operating mechanism comprising a cock operating lever, a switch operating lever, a sliding bar, a projection on said bar for engaging and moving the cock operating lever upon a sliding n1ovement of said bar in one direction, and a projection on said bar for engaging and m0ving said switch operating lever upon a further sliding movement of said bar, and manually operable means for shifting said bar.
3. A cook and switch operating mechanism comprising a cock operating lever, a switch operating lever, a sliding bar, means on said bar for engaging said levers and so disposed that the switch operating lever is first operated and then the cock operating lever upon a movement of said bar in one direction, and the cock operating lever is first operated and then the switch operating lever upon a movement of the bar in the opposite direction, and manually operable means for moving said bar in either direction.
In testimony whereof I have hereunto set m hand.
