STEVEN PANTAGES W AWWfl/Vfi United States Patent MULTIPLE REMOTE CONTROL SWITCH Steven Pantages, New York, N. Y. Application January 28, 1953, Serial No. 333,693 10 Claims. (Cl. 200-11) This invention relates to electrical switches and, more particularly, to a multiple contact control switch.
A primary object of the present invention is to provide an electrical switch which is capable of employment for a wide variety of purposes, such as for servocontrols, electronic computers, potentiometers, delay lines, remote control devices, timed controlled mecha ni'sm's, in the laboratory and in allied fields.
Another object of the invention is to provide a switch of this kind which will be simple to make, easy to assemble and adjust, positive in action, efiicient and durable in service and a general improvement in the art.
Other objects of the invention are to provide a switch of this character which avoids jamming, makes timing possible, avoids crowding of contacts and makes recycling of a helical switch possible. I V
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 14 is a diagrammatic view of a modification of the invention connected to the tuning control mechanisiir of a radio receiving set;
Fig. 15 is a a diagrammatic view of another modification of the invention connected to the rudder of a boat.
Referring to the drawings in detail, in Figs. 1 to 6, inclusive, the form of multiple remote control switch shown therein includes a disc 10 of insulating material and another disc 11 of similar material spaced from the disc 10 by a spacer ring 12 thereby providing a space 13 between the discs for receiving the switch arm mechanism hereinafter to be described. The discs are formed with central openings 14 to receive a rotatable shaft 15, which extends outwardly of both discs. The discs are held in spaced relation by screws 16 passing through he discs and the spacer ring 12.
Formed upon the inner surface of the disc 10 is a spiral or helical groove 17 of uniform depth except at the beginning thereof indicated at 18 and at the end thereof indicated at 19 whereby transition points are formed (see Fig. 4) for transferring from the deep part of the groove 17 to the face thereof.
The shaft 15, at the point where it passes across the space between the discs 16 and 11, is formed with a transverse opening 23. A sleeve 24 is secured in this opening and extends on both sides of the shaft. A rod or arm 25 is slidably and radially displaceable in the sleeve. Movably mounted on one end of the rod is a contact finger 26 of a length equal to the width of the space 13 plus the depth of one spiral groove. 7
By reason of this construction, it will be understood that during a rotation of the shaft 15, the contact finger 26 moves in either the spiral groove 17 of disc 10 or the spiral groove 20 of disc 11 depending upon the direction of rotation at the end portions 18 and 19 of disc 10 and 21 and 22 of disc 11, at which points the contact finger is transferred from one spiral groove to the other.
A plurality of stationary contacts 27 and 28 are mounted in grooves 17 and 20, respectively, said contacts having terminals 29 and 30, respectively, extending to the outer surface of the discs.
The contact finger 26 is adapted to ride in the groove of either disc. For example, if the contact finger 26 is at the end of the groove 17 of disc 10 and the shaft 15 is turned in one direction, the contact finger will ride around the groove with its end engaging the contacts 27 in said groove to close the circuit at each con tact. When the finger reaches the transition point 19, it will ride up the slanting portion thereof and be cammed into or transferred to the end 22 of the groove 2i) in the opposite disc 11 and carried around said groove 20.
In the modification shown in Fig. 9, the arm or rod 25 is formed with an extension 31 having a contact finger 32, which finger upon rotation of the shaft 15" rides in the groove or template 33 shown diagrammatically. This movement of finger 32 is imparted, through the rod 25', to the contact finger 26' on the opposite end of the rod 25. The finger 26 is adapted to ride in a groove or path 34 similar in shape and construction to the groove or template 33. The template or groove 33 can be of any shape desired. A template similar to template 33 can be placed in parallel with the end portions 18 and 19 of disc 10 of Fig. 4 and with the end portions 21 and 22 of disc 11 of Fig. 5, which end portions form the transition points for transferring the contact finger 26 from the groove of one disc to the groove of the other disc. The groove or path 34 in which the contact finger 26', rides may contain a resistance wire or delay line 35, such as shown in Fig. 11.
In all other respects, the form of the invention shown in Fig. 9 is the same as the form of Figs. 1 to 6 and similar reference numerals are used to indicate similar parts.
The modified form of switch shown in Figs. 8 and 10 includes spaced upper and lower discs 10 and 11", respectively, which discs are held in spaced relation by sleeves 36 and are secured together by bolts 37 passing through the sleeves. The discs 10 and 11" have spiral grooves 33 and 39, respectively, on their inner surfaces. The grooves 38 and 39 have stationary contacts 40 and 41, respectively embedded therein. This form of the invention includes modified recycling mechanism for positioning the switch contact arm for contacting the stationary contacts of either the upper disc 10" or the lower disc 11". This mechanism includes the contact arm of rod 25" with its contact finger 26".
The contact finger 26" is normally urged into contact with the contacts 41 of the lower disc 11" by means of a coiled spring 42 on the shaft 15'. A block 43 is slidably mounted on the inner surface of the bottom disc 11" and is guided in its movement by guides 44 on said bottom disc. The block is operatively connected to the shaft 15" and is formed with a camming surface 45 for engagement with the arm or rod 25'.
In order to move the contact finger 26 into contact with the contacts 46 of the upper disc 10", the shaft 15" is manually rotated counterclockwise, as viewed in Fig. 8, by a knob 43 on top of shaft 15". Movement of the shaft moves block 43 which in turn forces a fiat latch spring 46, carried by the block, to become disengaged from :a stop 47 on the disc 10".
In order to return the finger 26 to contacting engagement with the contacts 41 of the lower disc 11', the shaft 15 is "turned clockwise whereby the 'block 43 is moved away from arm 25" to normal position with the latch spring 46 in holding position with the stop 47, permitting the spring 42 to urge the finger 26" downwardly into contact with the contacts 41. The arm 25 in its up and down movements is guided by an extension 42 on the top edge of the hub portion 44' coacting with guides 41' on top of the shaft 15".
In Fig. 8, the shaft has been turned clockwise and the contact arm 25 is shown in solid lines in lower position. The arm is shown in dotted lines in the upper position it assumes when the shaft is turned clockwise.
In Fig. 13, the improved switch is shown as a station selector for a radio receiving set. The movable switch arm 25 is extended and mechanically connected to a moving part of a clock mechanism shown diagrammatically at 48 by a rod 48, and is electrically connected to a radio receiving set shown diagrammatically at 49, by conductors 50, 51 and 52 leading to mechanism shown in detail in Fig. 14. Inserted in the surface of disc 10 of the switch in the path of movement of the contact finger 26 of the contact arm 25 are arcuate-shaped tuning contact members 53 and 54 in spaced relation, and arcuate-shaped duration contacts members 55 and 56. The tuning contacts 53 and 54 are connected electrically by the conductors and 51 and 52 to a double relay ratchet wheel operating mechanism shown in detail in Fig. 14. The switch contacts for turning the tuning condenser clockwise are connected to the conductors 50 and 51 and for turning the tuning condenser in a counterclockwise direction are connected to the conductors 51 and 52..
It will be understood that the switch may also be used as an automatic control device for timed operations applicable to boats, and may be used in connection with gyroscopic and orientation mechanisms.
In use, assuming that a program on the radio is desired which goes on in an hour and is of one-half hour duration. The present dial setting of the radio receiving set is observed and the number of divisions to the desired station is calculated. The movable arm 25 of the switch is then set so that an equal number of spaced contacts are interposed between the said arm and the duration con tact which is in its path of movement. Upon move ment of the switch arm 25, it engages contacts 27 successively and upon each engagement closes the circuit through relay 57 (Fig. 14) thereby energizing the same and causing the relay to turn the ratchet wheel '58 in a. clockwise direction, for example, as viewed in Fig. 14. The ratchet wheel 58 in turn rotates the tuning condenser of the radio receiving set.
The spaced switch contacts provided for tuning the tuning condenser in a counterclockwise direction are connected to relay 59 (Fig. 14) which when energized turns the ratchet wheel 58 in a counterclockwise direction and thus turns the tuning condenser in a similar direction.
A similar switch placed in exact parallel position could control the volume control mechanism of the radio receiving set, but transition points would then be necessary.
In Fig. 14, the improved switch is shown connected to relay mechanism for remotely controlling a television set. The relay mechanism includes the opposed relays 57 and 59. An armature 60 is interposed between the relays and is suspended from a rod 61 which is operatively connected to spokes 58 the ratchet wheel 58 through a V-shaped member 61. The ratchet wheel is mounted on a shaft 62 which in turn moves pulleys 63 and 64 through a flexible connection 65 for turning the shaft 66 of the dial of the television set. Relay 57 is connected by conductors 67 and 68 to the contacts of the upper disc 10' of the switch, and the relay 59 is connected by conductors 68 and 69 to the contacts of the lower disc 11' of the switch.
In all other respect-s the form of the invention shown in Fig. 14 is the same as the form shown in Figs. 8 and 10 and similar reference numerals are used to indicate similar parts.
Fig. 15 shows a modified form of remote control switch mechanism for controlling the movement of the rudder 74 of a boat. In this form, the switch shown diagrammatically at 75 controls, through the conductors 76 and 77, the frequency of the transmitter 78. Signals from the transmitter are transmitted through the antenna 79 to a re ceiving antenna 80, and, depending upon the frequency of the signals, are turned in by either receiver 81 or receiver 82. One of the receivers is tuned to a low frequency and the other to a higher frequency. Receiver 81 is connected by conductors 83 and 84 to a relay 85, and the receiver 82 is connected by conductors 86 and 87 to a relay 88. An armature 89 is interposed between the relay devices and is suspended from a rod 90 which is operatively connected to a ratchet wheel 91 mounted on a shaft 92. The rudder 74 of the boat is connected to shaft 92 and actuated thereby. The position of the rudder is predetermined by calibration of the switch 75 by means of a knob 75 and scale 75". The output of receiver 81 energizes relay for moving the ratchet wheel 91 in one direction, and the output of receiver 82 energizes relay 88 for moving the wheel in the opposite direction, the operation of the respective receivers depending upon the frequency of the signals transmitted. A resistance device 93 may be provided for retracting the armature 89 to normal position.
Fig. 7 discloses a modified form of switch contacting arm 25" which is secured at one end to the shaft 15" but which mounts a contact finger 26' slidable along the arm. The contact finger moves radially and transversely. Fig. 11 shows the arm 25" and contact finger 26'" of Fig. 7 embodied in a switch for use with a potentiometer. In this form, the resistance wire 35 is embedded in each of the grooves 17 and 20 in the disc members 10 and 11, respectively, which wires contact terminals 29' and 30" in the disc members 10 and 11, respectively.
In all other respects the form of invention shown in Fig. 11 is the same as the form in Fig. 1 and similar reference numerals are used to indicate similar parts.
In Fig. 12 is shown a modified form of switch disc member 10" having a short arcuate shaped groove 94. This groove serves as a return path for the contact member 26 in order to begin recycling in either direction.
In all other respects the form of Fig. 12 is the same as the form shown in Fig. l and similar reference numerals are used to indicate similar parts.
