6 Claims.
My invention relates to remote control systems and particularly to a system for selectively starting and stop D 8 the movement of a device in different directions, and its object is to provide an improved arrangement for accomplishing this 7 result.
My invention will be better understood from the following description whenv taken in connection with the accompanying drawing, the single figure of which diagrammatically illustrates a reversible motor remote control system embodying my invention, and its scope will be pointed out in the appended claims.
Referring to the accompanying drawing, l rephaving an armature 2, and two field windings 3 and. 5 is a relay which, when energized, completes a circuit through the armature 2 and field winding 3 in series so that the motor rotates in one direction, andt is a relay which, when energized, completes a circuit through the armature 2 and held winding 4 in series so that the motor 2 rotates in the opposite direction. For remotely controlling the starting and stopping of the motor 'I, I provide a manually controlled switch I which in one position-connects a conductor, 8 to the positive terminal of a suitable source of direct current such as a battery i0 and which in another position connects the conductor 8 to the negative terminal of the battery it. A conductor 9 is permanently connected to the middle or neutral terminal of the battery.
Therefore, by moving the switch I, the operator can transmit impulses of opposite polarity over the two conductors I and 9. Connected across the conductors 8 and 8 is a polarized relay H,
which is arranged to close its contacts l2 when the switch 1 is closed so as to transmit a positive impulse over the conductors 8 and 9 and is arranged to close'its contacts l3 when the switch I is closed so as to transmit a negative impulse over the conductors 8 and 9 and to move to its midposition as shown in the drawing when no.
control relay I4 is energized and the control relay 0 II is deenergized an energizing circuit for the relay 5 is completed to eilect the operation of the motor I in one direction, and when both of the relays l4 and I! are simultaneously energized this energizing circuit of the relay 5 is opened to E eiiect the stopping of the motcr'l. Similarly,
resents a remotely controlled reversible motor,
when the relay I5 is energized, and the relay I4 is deenergized the relay l5 completes an energizing circuit for the relay 6 to efiect the operation of the motor i in the opposite direction. When, however, both of the relays II and 15 are simultaneously energized, this energizing circuit of the relay 6 is opened to eflfect the stopping of the motor i. The relay [6 is a time relay which is energized when both of the relays I4 and ii are energized to control the energization of these 19 relays, and the relays 5 -and 6 in the desired manner.
The operation of the arrangement shown in the drawing is as follows: When it is desired to start the remote motor I revolving in a prede- 15 termined direction, the operator at the controlling station moves the switch 7 so as to connect the conductor 8 to the positive terminal of the battery HLthereby causing a positive impulse to be transmitted over the conductors 8 and 9. This 20 positive impulse causes the polarized relay II to close its contacts I 2 and thereby complete an energizing circuit for the relay H. By closing its contacts 20, the-relay ll completes a locking circuit for itself through the contacts 2| of the 25 relay It. By closing its contacts 22, the relay ll completes an energizing circuit for the relay 5 through contacts 23 of the relay l5 and the contacts 24 of the relay It. The relay 5, by closing its contacts 25, completes a circuit for the field 30 winding 3 and armature 2 of the motor i so that the motor rotates in one direction. Since the relay completes a locking circuit for itself, it will be observed that the motor circuit remains completed after theposltive impulse has been terminated by the operator moving the switch 1 so as to disconnect the conductor 8 from the positive terminal of the battery Hi.
When it is desired to stop the motor I after it has been started by the transmission 01 a positive impulse over the conductors 8 and 9, the operator at the controlling station moves the switch 'I so as to connect the conductor 8 to the negative terminal oi the battery in, thereby causing a negative impulse to be transmitted over the conductors 8 and 9. This negative impulse causes the polarized relay II to close its contacts I: and thereby complete an energizing circuit fol-the relay [5. By closing its contacts 26, the relay i5 completes another holding circuit for the relay I through contacts l3 of the relay II and contacts 20 of the relay II. By opening its contacts 23, the relay it opens the circuit 01 the relay 5, which in turn opens the circuit through the field winding I and theannature2oi'themotor [,soastoeflectthe stopping of the motor i. By closing its contacts Ell, relay l5 completes an energizing circuit for the relay iii through contacts iii of the relay i i. A short time after relay it is energized, it opens its contacts it in the original holding circuit of relay i l and its contacts 26 in the circuit of relay 5. Relays i l, i5, and iii, however, remain energized as long as the negative impulse continues to how through the conductors it and it but the movement of the motor i is stopped as soon as the relay iii picks up. At the termination of the negative impulse, polarized relay it opens its contacts it; so that relays i l and it are ole-energized and they in turn efiect the deenergization of relay it.
When it is desired to start the motor i rotating in the opposite direction, the operator in the com trolling station moves the switch '3 so as to transmit a negative impulse over the conductors ii and lihis negative impulse causes the relay ii to close its contacts ldand complete an energizing circuit for relay iii, which in turn, by closing its contacts completes a locking circuit for itseli through contacts it of relay Hit. By closing its contacts relay in completes an energizing circuit for relay ii through contacts Elli of relay M and contacts 2 3 of relay iii. Relay t, by closing its contacts ill, completes a circuit for the field winding d and armature 2 oi motor 11 so that the motor rotates in the opposite direction. Since the relay l5 completes a locking circuit for itself, it will be observed that the motor circuit remains completed after the negative impulse is termi nated by the operator moving the switch ll so as to disconnect the conductor 8 from the negative terminal-of battery Elli. When it is desired to stop the motor after it has been started by the transmission or a negative impulse over the conductors and the operator at the controlling station moves the switch i so as to transmit a positive impulse over the conductors i) and This positive impulse causes the polarized relay i l] to close its contacts i2 and complete an energiz= ing circuit for relay i l. By closing its contacts iii, relay M completes a holding circuit for relay is through contacts 2d of relay i5 and contacts it of relay ii. By opening its contacts so, the relay i l opens the circuit oi relay ti, which in turn opens the circuit through the field winding i and armature 2 of motor i so as to sheet the stopping of the motor. By closing its contacts Zil, relay to completes an energizing circuit for relay iii through contacts Z'l oi relay it. A short time after relay it is energized, it opens its contacts ii in the original holding circuit of relay i5 and its contacts 2d in the circuit oi relay t. At the termination of the positive impulse, the polarized relay it opens its contacts 62 so that relays id and.
is are de-energized and they in turn efiect the de-energization of relay it.
From the above description, it will be seen that when the motor 11 is at rest its rotation in one direction may be initiated by transmitting an impulse of one polarity over the conductors ii and ti, and its rotation in the opposite direction may be initiated by transmitting an impulse of the opposite polarity over the conductors t and 9 and that when the motor is rotating it may he stopped by transmitting over the conductors ii and d an impulse of the opposite polarity from the polarity of the impulse which started the motor rotating.
