CONTROLLING DEvIcE FOR THE DRAINAGE OF THE STEAM CYLINDER IN AN AUXILIARY PLANT OF A LOCOMOTIVE Filed Feb. 23, 1953 I Lgdsay \NVENTOFL AWL b U Y Patented Sept. 24, 1935 UNITED STATES PATENT OFFIE CONTROLLING DEVICE FOR THE DRAINAGE OF THE STEAM CYLINDER IN AN AUXIL- IARY PLANT OF A L OCOMOTIVE Application February 23, 1933, Serial No. 658,043 In Czechoslovakia March 23, 1932 2 Claims.
were much too complicated and dimcult to adjust to the varying weather conditions.
The present invention solves the problem of controlling the drainage device.
The essence of the present invention consists in apparatus assuring the drainage device always being automatically opened either at the same time, or before, the auxiliary plant is shut down, while, when the auxiliary plant is running this device still remains open until the engineer, after accompanying drawing. In this example com pressed air or other fluid medium is used for controlling the auxiliary plant, and also for controlling the drainage device. In this connection the manner of starting and stopping the auxiliary which are so controlled, V the piston of the auxiliary air cylinder, that after the inflow of compressed air under the piston the drainage organs close, while, after the compressed air has been released from the cylinder,
a spring arranged in the appropriate place opens these organs.
In the accompanying drawing the primary three-way cock I is shown as the control organ which controls the shutting down and starting up of the auxiliary plant, and the secondary three-way cock 2 as the regulating organ which actuates the opening and closing of the drainage device. Figures 1, 2 and 3 show diagrams of the corresponding positions of both three-way cocks at different phases of starting up the auxiliary machine the drainage device being shown at the left of Figure 1, and Figures 4 and. 5 are views of the corresponding arrangements of levers which connect these cocks. V
The compressed air is supplied to the cocks I and 2 through the pipe 3. The pipe 4 leads from the cock I to the starting device of the auxiliary machine and, as soon as the compressed air reaches this pipe, the auxiliary machine is put into operation, that is, started up; when the compressed air fiows out of the pipe the auxiliary machine is shut down. The manner in which this is done is not the subject of this invention, and it is therefore not necessary to go any further into this. The pipe 5 leads to the previously men-.
tioned air cylinder of the drainage device. channels 6 and 7 act as exhausts, for example, into the atmosphere.
The cock I is actuated through the lever B by means of the connected link rod l 0 and the hand lever 9. This lever 9 is provided with a handle and the other limb l i is connected by alink to the spring l2, which is so placed relative to the pivot 01' the lever 9 that it secures both limiting positions of this lever. The cock 2 is actuated by the lever l3 which is provided with a handle and carries a pin it which can engage in the stop I5 which is arranged at one side of the lever [0.
The operation of the device indicated in this example is as follows: With the auxiliary machine shut down the respective positions of the cooks are as shown in Figure l, and the position is connected to atmosphere I, so that the auxiliary machine is shut down; the pipe 5 is also connected with the exhaust 6 and the drainage 7 device thus opened as shown in the left hand part of Figure 1. At the same time the lever 9 assumes'the position of Figure 4 and is secured in this position by the spring it, while the onesided stop is of the rod ll! holds the pin it of the lever 53 in the position indicated.
When starting up the auxiliary machine it is necessary to turn the lever 23 towards the left into the position shown in Figure 5, whereby simultaneously the lever B of the cock I is also turned towards the left, while the lever 33 of the cock 2 remains in its original position; it is merely no longer secured by the stop 15. The position of the cocks is now asshown in Fig ure 2. The compressed air from the pipe 3 passes through the cock I into the pipe 4, whose connection with the exhaust 1 is interrupted and the auxiliary machine is started up. As the lever i3 has remained in its original position, the cock 2 does not alter its position, and the pipe 5 remains connected to the exhaust 6 so that the drainage device is still open.
After a certain time, depending on the season and the weather, when the engineeer has made certain that all the water has passed off from the auxiliary plant and the pipe, he turns the lever l3 by hand into the position 13 (Figure 5) whereby the cock 2 is also turned into the-position indicated in Figure 3. The compressed air from the pipe 3 fiows into the pipe 5, whose connection with the exhaust is interrupted, and closes the drainage organ.
At any time while the auxiliary machine is working, it is possible, by turning the handle l3, to open the drainage device and to close it again.
The auxiliary machine is thrown out of service by turning the lever 9 from its position in Figure 5 into the position shown in Figure 4, whereby the one-sided stop !5 of the rod is) strikes against the pin M of the lever is and, as a result, not only the cock I, but also the cock 2, is turned into its opened position so that the air fiows out from the tubes 4 and 5 to the exhausts 'l and B, and the auxiliary machine is shut down while the drainage device opens. Thus, with this method, when the auxiliary steam plant is shut down,,the drainage device isalways simultaneously and automatically opened, thereby excluding the possibility of the engineer for getting to do this. t
It is advantageous to make the spring H, which controls the opening of the drainage device, so strong that the drainage device opens somewhat earlier than the shutting down of the auxiliary steam plant. The oil which collects at the drainage organ while the plant is running is, by this method, properly blown out by means of steam under full pressure, so that the drainage organs remain clean and do not get choked up.
It is also advantageous to have the throw of the pin [4 sufficiently smaller than the throw of the stop l5 that it is possible to openthe cock 5 2 by the movement of the lever 9, but, on the other hand, it is not possible when moving the lever 13 back, to carry the spring I over the dead centre that is, it is not possible to start up the. auxiliary plant. In this way the lever I3 r and the cock 2 are secured in their opened position during the whole time that the auxiliary plant is shut down' What I claim'and desire to secure by Letters Patent of the United States is:- 15 1. In an apparatus for the purposes specified,
two three-way cocks, an operating lever mounted on the first cock, a first hand operated lever having two end positions, a rod interconnecting said levers, a second hand operated lever mounted on the second cook, a lug projecting from the second hand lever, a projection on said'rod engaging said lug only in certain relative positions of said lug and projection but free to move with respect thereto, whereby upon the movement of the first hand lever into one position the first cock is operated but the second cock is not operated by said rod, and upon the movement of the first hand lever into the second position the projection on the rod will engage the lug on the'second hand lever and rotate through it the second cock from the position into which it may have been moved by the second hand lever into its normal position, the leverage on the elements being such that the first hand lever cannot be moved into the first end position by the actuation of the second hand lever.
2. The apparatus according to claim 1 and in which the first hand lever is pivoted and is provided with an arm, a spring fastened to said arm 0. to maintain the first hand lever in either end position, whereby when the second hand lever is rotated to displace the first hand lever towards the first end position the first hand'lever does not move past dead center andis returned by 5;- said spring into its second position when the pressure on the second hand lever is relieved.
