My invention relates to control systems and, more particularly, to control systems which may be utilized to operate a plurality of current-responsive devices.
5 An object of my invention is to provide a simple, reliable and inexpensive electrical control system for actuating a plurality of current-responsive devices in timed sequence.
It is also an object of m invention to provide for actuating a plura ity of currentresponsive devices, in timed sequence, by electronic means.
A more specific object of my invention is to provide for utilizing a discharge device and a timing circuit to operate a plurality of current-responsive devices which function to connect, successively, the discharge device and its associated timing circuit with each current-responsive device.
Other objects of the invention will hereinafter become apparent. I
This invention, accordingly, is disclosed in the accompanying drawing and comprises the features of construction, the combination of elements and the arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and the objects of the invention, reference should be had to the following detailed description, taken in connection with the accompanying drawing, in which,
Figure 1 is a diagrammatic view of a control system constructed in accordance with my invention, and l I Fig. 2 is a diagrammatic view oi a modified form of the control system.
In general, my control system provides for operating a plurality of current-responsive devices, in timed sequence, by utilizing an electric-discharge device and a timing circuit connected in circuit relation thereto. The
" timing circuit provides for controlling the electric-discharge device, whereby the plurality of current-responsive devices may be successively actuated at definite intervals of time which depend, for their duration, upon the time constant of the timing circ ;it.
1931. Serial No. 530,926.
the discharge device and the timing circuit are successively connected in circuit with each of the current-responsive devices.
In other words, a definite time interval after the establishment of an energizing circuit for the timing circuit and the discharge device, depending on the time constant of the timing circuit, operation of the first of a series of current-responsive devices is effected. Operation of the first current-responsive device interrupts the circuit for the discharge device and establishes circuits whereby the second current-responsive device of the series is connected in circuit with the discharge device. After a predetermined interval of time, as determined by the time constant of the timing circuit, the discharge device functions'to energize, and thus actuate, the second current-responsive device which thereupon causes the deenergization of the discharge device, and the connection of the discharge device in circuit with a third current-responsive device. According to my invention, as just broadly outlined, any number of current-responsive devices may thus be operated in timed sequence.
Referring to Fig. 1 of the drawing, the reference characters 10, 11 and 12 designate, generally, a plurality of current-responsive devices, such, for example, as relays which may be utilized to operate electric motors or any other electric devices. Although only three relays are shown in Fig. 1, it will be readily understood that any number of relays may be associated with the discharge device, designated generally by reference character 15.
The electrical-discharge device 15 is provided to actuate the relays in timed sequence. As shown, this device comprises a control electrode 20, a cathode 17 and an anode 18, which elements will be designated as the principal electrodes whenever the control electrode is subjected to potential of the proper value and sign relative to the principal electrodes the ischarge device becomes conducting, thereby permitting direct current to flow between t e principal electrodes.
The timing circuit comprises a ca acitor 32 and a variable resistor 30 connects in circuit with the control electrode through acurrent-limiting resistor 34. A source of direct-current power of ap connected across the an e and cathode. By appro riate adjustment of the timing circmt, t e potential of the, control electrode, relative to the principal electrodes, when the timing circuit fully char ed may be predetermined whereby the discharge device may be caused to function a predetermined interval of time after being connected to the source of supply.
The discharge device and its associated timing circuit and the relays are disposed to be energized from the.supply conductors and 27 which ma be connected to any suitable source of irect-current power (not shown).
To efl'ect the operation of the relays in timed sequence, each relay is provided with a pluralit of contact fingers and contact segments. is shown, the actuating coil 13 of the relay 10 is connected in circuit with the discharge device 15 throu h the upper or back contact members 35. enthe timing circuit has been fully charged, the discharge device functions, w ereupon current flows from the positive conductor 25, through conductor 19, the principal electrodes 18 and 17 of the discharge device 15, the conductors 21,
22 and 23, the contact members and the actuating coil 13, of the relay 10 to the negative conductor 27.
As will be noted, when the armature of the relay is raised, the circuit above traced is broken at the contact members 35 and, in consequence, the discharge device is deenergized. However, the momentum, ac uired by the upwardl moving armature wi 1 be suflicient to cause it to continue its movement, thereby establishing a holding circuit from positive conductor 25, through'conductor 48, contact members 40, and actuating coil 13, to the negative conductor 27 "Operation of the relay 10 also efi'ects the closing of the contact members 45, whereby a circuit is established from the positive conductor 25, through .conductor. 19, anode 18, cathode 17, conductors 21, 22 and 24, contact members of the relay 10, conductor 26, upper or back contact members and the actuatin coil 54 of the relay 11, to the negative con uctor. Since the opening of the contact members 35 deenergizes the discharge device 15, the timing circuit is subjected to a charging .action from the direct-current source of power the instant the discharge through the device 15 ceases. A predeterropriate voltage is mined interval of time after-this action takes efiect, depending on t e adjustment of the timin circuit, the discharge device again functions, thereby permit-ting current to flow through the actuating coil 54 by the circuit above traced. Operation of the relay 10 interrupts the circuit for the discharge device at contact members 35; establishes its own holding circuit through contact members 40; and connects the principal electrodes of the discharge device in circuit with the actuating coil 51 of the relay 12. The cycle of operation just explained may be repeated again and again, thus controlling an indefinite number of relays;
In explaining the operation of the control system, more in detail, it may be assumed t at the su ply conductors 25 and 27 are energized. mmediately upon the energization of the timing circuit, the capacitor 32 will begin to charge throu h the variable resistor 30. As will be readi y understood, the rate at which the capacitor is charged depends upon the settin of the variable resistor 30. When the capacitor is charged to a predetermined extent, the control electrode 20 attains such potential, relative to the principal electrodes 17 and 18, that the discharge device becomes conducting, thereby causing the operation of rela 10, as heretofore explained.
Operation 0 the relay 10 causes interruption of the circuit from conductor 19 through anode 18, cathode 17 and coil 13, but, at the same instant or a trifle later, (depending upon the design of the relay) a holding circuit is established for coil 13 through contact members 40. It is, of course, apparent that the disposition of cont-act members 40 with reference to contact members 35 may be such that the holding circuit is established an instant before the circuit is interrupted at contact members 35. In any case, the discharge device is deenergized when the contact members of relay 10 move to their operative positions.
Operation of the contact members to circuit-closing position connects the discharge device and its timing circuit in circuit with the relay 11. Upon the estabYishment of this circuit, the capacitor 32 will again begin to charge through the variable resistor 30. When the capacitor is charged to a predetermined extent, the discharge device a ain becomes conducting, and current ows through the principalelectrodes to energize the actuating coil 54 of the relay 11.
Relay 11 is, in every particular, like relay 10 and, when caused to operate, as just explained, repeats the cycle of operation efiected by relay 10. It is thus apparent that the repeated functioning of the discharge device may cause the operation of any number of relays 10, 11, 12, etc., in timed sequence.
A modification of the control system shown in Fig. 1 is illustrated in Fig. 2, wherein two discharge devices and 61 are utilized instead of one. The functioning of these discharge devices is thesame as that described for the discharge device in Fig. 1, with the exception that the relays which are to be actuated are alternately connected in circuit with the discharge device. In other words, the functioning of the discharge device 60 actuates the relay 65. Operation of the relay 65 connects,the discharge device '61 and its associated timing circuit in circuit with the relay 66 through the contact members 70, of the relay 65, whereupon relay 66 is caused to operate by discharge device 61. Operation of relay 66 connects the discharge device 60 and its controllin timing circuit in circuit with the relay 67 through the contact members 7 4 of the relay 66. In a similar fashion, the operation of the relay 67 connects the discharge device 61 and its controlling timing circuit in circuit with the relay 68. It is evident, therefore, that any number of relays may be alternately connected to a plurality of discharge devices having equal or unequal time constants.
