Definitions

  • the present invention relates to remote control apparatus, and more particularly to apparatus for the remote control of switches or other electrical apparatus.
  • the invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.
  • Figure 1 is a diagrammatic view illustrating one of the embodiments of the present invention.
  • FIG. 2 is a fragmentary diagrammatic View illustrating another typical embodiment of the invention.
  • the present invention has for its objects the provision of a novel and improved remote control system for selectively performing different operations. Another object is the provision of an improved remote control system which is reliable in operation and simple in construction. Still another object is the provision of an improved step-by-step switching apparatus for selectively performing various operations.
  • an electromagnetic step-by-step actuated contact selector mechanism in which the selection of the desired contact is determined by the number of impulses received by the selector mechanism. Means are also provided for momentarily passing an electric current through the selected contact, to effect the desired operation, and for initiating operation of a reset mechanism by which the contact selector mechanism is returned to its initial position to await a new series of impulses.
  • the series of contacts are preferably arranged in a circular path, and the selector comprises a contact arm moved step-by-step by impulses received by its actuating mechanism.
  • the first impulse received by the actuating mechanism moves the contact arm from its position of rest, and also starts the operation of the resetting mechanism, which operates considerably slower than the actuating mechanism.
  • the number of impulses received determines the particular contact to which the arm is moved, and after the contact arm has been moved to its proper position a momentary current is passed through the contact 5 arm and the particular apparatus connected therewith. Thereafter, the operation of the reset mechanism continues, finally returning the contact arm to its initial position and also stopping the operation of the reset mechanism.
  • the apparatus includes three principal parts: the step-by-step' actuating mechanism, the contact selector, and the resetting mechanism.
  • the step-by-step actuating mechanism comprises an electromagnet in having a pivoted armature II to which is pivoted a pawl rod I2 cooperating with ratchet l 3 to move it in the direction of the arrow.
  • a detent i4 is provided to prevent retrograde movement of the ratchet, while a return spring I5 is connected with the pawl rod I2 and actuates the pawl after it has been retracted by its armature H.
  • lheelectromagnet l0 receives its energizing current from the wires I6, by which it is connected with an impulse transmitter (not shown) adapted to transmit any desired number of impulses with more or less predetermined regularity.
  • the contact selector comprises a disc 20, formed with a peripheral notch 2
  • a contact arm 23 is mounted between ratchet l3 and disc 20, and is held against angular displacement with respect thereto by means of screws 24. Arm 23 is adapted to coact with contacts 25, arranged in a circular series, and is electrically connected with a slip ring 26 through which it receives current from brush 21.
  • Ann 23, disc 20 and ratchet 13 are freely rotatable on shaft 28 and are moved thereabout by means of the magnet I 0 and pawl, so that continued operation of the pawl causes the contact arm to be passed over the several contacts 25 in sequence.
  • the teeth of the ratchet i3, and the stroke of the pawl are so related to the spacing of the contacts 25 that three impulses are required to move the contact arm from one contact to the next, but this number may be varied.
  • the resetting mechanism comprises a motor 5 v 30, such as a small Ferraris motor, which is geared to a disc 3! rotatable on shaft 28 by means of gearing 32.
  • the motor receives its energizing power from the mains through conductors 34 5 and a switch comprising contacts mounted on springs 35 and 36, normally spaced apart but pressed together to close the motor circuit as disc 20 is moved from its normal position of rest and notch 22 is moved away from the spring 35.
  • is provided with a laterally extending arm 3'! to contact with arm 22 as the disc 21"! rotates and thereby move disc 26 and its connected contact arm 23 to their initial position at which time notch 2! permits the springs 35 and 33 to move apart opening the motor circuit and stopping operation of the resetting mechanism.
  • Disc Si is also provided with a projection 38 adapted to contact with a projection on contact spring 38 and mon'ien'tarily move it into contact with its cooperating cont-act spring it.
  • current is supplied from mains v33 through conductors 4
  • the mechanisms 42 may be switching mechanisms, register-shifting electromagnets in a multiple-rate meter or other control mechanisms adapted for selective operation.
  • the speed of motor 36 and the gear ratio between it and the disc 3! is preferably so related to the normal speed of operation of ratchet l3 that the contact arm will be moved from its normal position and sequentially into contact with all of the contacts 25 before projection 38 has been moved to close switch 39, 43, thereby insuring that the momentary supply of current to contact arm 23 will not occur until after arm 23 40. has been moved into operative relation with respect to the desired contact 25.
  • a plurality of short, rapid impulses are transmitted and re- 45 ceived by the electro-magnet l0, causing the ratchet I3, contact arm 23 and disc 20 to be rotated step by step until contact arm 23 is in contact, with one of the contacts 25, the selection of any particular contact being determined by the 50 number of impulses received.
  • the first of these impulses moves notch 21 on disc 26 out of position with respect to the spring 35, thereby closing the resetting motor circuit and starting motor 39 in operation.
  • Reset motor .36 drives disc 3! in thedirection of the arrow and after contact arm 23 has engaged the proper contact, the projection 33 on disc 3
  • spring mounted contacts may be provided in place of the contacts 25, and disc 20, and contact arm 23 may be replaced by an arm 50.
  • arm 50 is mounted on shaft 28 and is driven step-by-step by means of ratchet I3 to 10 which it is rigidly fastened. In its normal position of rest, arm 50 holds open the spring mounted contacts 35', 35' preventing operation of the resetting motor, but as soon as the arm is moved from this position, these contacts close and place 15 the resetting motor 30 in operation.
  • the selectively closed contacts for controlling the various mechanisms 42 each comprise a pair of spring mounted contacts 52, normally spaced apart but closed by pressure of arm 53 as it moves about 20 shaft 28.
  • Contacts 52 are arranged in a circular path so that they are sequentially closed by passage of arm 50. These contacts 52 are connected 1 in parallel with respect to each other, but are connected in series with the momentarily closed 25 switch 39, and also in series with their respective mechanisms 42.
  • the contact selector arm 50 may be moved and reset by mechanism similar to that shown in Fig. 1.
  • An electrical remote control receiving de-- vice including in combination a plurality of contacts, a rotary contact selector for said contacts 40' and having a normal position, a motor driven rotary resetting device for the contact selector and coaxial therewith, impulse actuated-means for rotating said selector, means for supplying current to said motor after a first'impulse and 45' until said selector is completely reset, and a switch operated by said resetting device for supplying current to said selected contact a predetermined time after said first impulse, after selec-' tion ofone of said contacts and before resetting of the contact selector.
  • An electrical remote control receiving device including in combination a plurality of contacts,
  • a rotary contact selector for said contacts and having a normal position
  • impulse actuated means for rotating said selector
  • means for supplying current to the selected contact andreset- I ting means including a motor driven rotary member to rotate said selector to its original, normalposition and set in operation by a first impulse 6O for controlling the supply of current to said selected contact, means connecting said rotary member and selector permitting said selector to be moved ahead of said member and means for stopping said motor when said selector has been fully reset, the speed of said motor being sufiiciently slow to permit selection of any contact before current is supplied to the selected contact and before resetting of the contact selector.
  • An electrical remote control receiving device including in combination a plurality of contacts, a rotary contact selector for said contacts and having a normal position, impulse actuated means for rotating said selector, means for supplying current to-the selected contact and reset r ting means including a motor-driven rotary member to rotate said selector to its original position and set in operation by a first impulse and having a cam for controlling and timing the supply of current to said selected contact, a lost motion connection between said selector and member permitting movement of said selector ahead of said member, the speed of said motor being sumciently slow to permit selection of any contact before current is supplied to the selected contact and before resetting of the contact selector and a cam driven by the motor controlling the power supplied to the motor for starting and stopping the motor.
  • An electrical remote control receiving device including in combination a plurality of contact segments, a rotatable contact to contact sequentially with said segments and having a normal position, a solenoid operated pawl and ratchet for advancing the rotatable contact to select one of the contact segments, a motor, a cam fixed to the rotatable contact, a switch controlling the power supplied to the motor and operated by the cam to start the motor upon the first operation of the solenoid and to stop the motor when the rotatable contact has been returned to its normal position, a switch operated by the motor for supplying a single impulse through the selected contact segment after selection and a 10st motion device interconnecting the motor and rotatable contact for returning the contact to its original position after an impulse has been transmitted through it.
