This invention relates to remote control mechanism especially applicable to adjusting radio apparatus such as radio antennae, dials and other adjustable parts.
The object of the invention is to provide means for adjusting movable parts which may be operated at any convenient position remote from the part to be adjusted.
The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims.
In the drawin Iiig. 1 is an elevation of the remote control dia Fig. 2 is a plan view, on a larger scale, of the dial shown in Fig. 1;
Fig. 3 is a vertical section through the remote control dial;
Fig. 4 is a horizontal section substantially on line 6-6 of Fi 3;
Fig. 5 is an end view of a socket for receiving the electrical connection for the mechanism shown in Fi 3;
Fig. 6 is a sectlon substantially on line 88 of Fig. 4;
Referring to the drawings, 62 designates a base upon which there is mounted a housing 63. Mechanism for producin electrical impulses is contained within the ousing 63 and comprises a star-wheel 67 secured to a spindle 68 which carries the dial 64 The star-wheel 67 is provided with a series of points 69 which engage rollers 70 and 71 mounted on fingers 72 and 73 which are carried by pivot screws 74 and 75. respectively, secured to a plate 76 which is su ported on the base 62 by suitable lugs 77. .e fingers 72 and 73 are providedwith springs 7 8 and. 7 9, respectively, having contact members 80 and 81 for engaging a contact 82 carried. on an arm 83 which is pivoted on the central spindle 68. The arm 83 has limited rotary movement about the spindle 68, the movement being controlled by a slot 84 which is engaged by a pin 85 on the end of the arm opposite the contact member 82. The mem ber 83 has a laterally projecting lug to which a link 86 is connected by a pivot 87. A roller 88 is journaled on the link 86 and engages the notches between the points 69 on the starwheel. A spring 89 holds the roller 88 in contact with the notches. The rollers 7 0 and 71 are also yieldingly held in the notches on the star-wheel by springs 90 and 91. A stop 92 is formed on the star-wheel 67 and engages a pin 93 extending downwardly from the case 63 to prevent more than one complete rotation of the star-wheel. If the dial 64 and the star-wheel 67 is rotated in a counterclockwise direction from the position shown in'Fi 4 it will be apparent that each time one 0% the points 69 passes the roller 70 the contacts 80 and 82 will be moved into engagement with each other. If the dial is turned to move two points past the roller 70, an antenna (not shown) which may be operativel connected with the switch will be accordmgly turned a corresponding amount. If a half revolution is imparted to the dial the antenna will be turned 90 and if a complete revolution is imparted to the dial the antenna will be turned 180. If it is desired to reverse the movement of the antenna it is only necessary to turn the dial in the opposite direction. The first effect of this will.
be to swing the arm 83 in a clockwise direction, as viewed in Fig. i, to bring the contact 82 opposite the contact 81. This is efliected by the roller 88 which is carried to the right in Fig.4 by the teeth 69 until its movement is linnted by the slot 84. Further rotation in the same direction will produce connection between the contacts 81 and 82 each time a point 69 passes the roller '71. The contact 81 may be connected with one of pair of magnets {not shown} so that the impulses imparted by this connection produce rotm pings 95. (inc oi is desired to connect the tbs sockets Q6 may be con nected with tbs-positive terminal of s bottery the other connected with the negotive terminal. Tbe-otber two sockets will lend to the magnets plug 95 which is connected to tbe socketi fi oi the neg'stive terminel oi the bettery leads to e connection 97 grounded on the base plots do of the housing for the diel mechanism. The magnets are provided with conductors 98, one conductor from each magnet being connected Wish tbs positive terminal of the battery while the other conductors extend through the cebie 9% to their respective contects 80 end 81. When e contact 80 or 81 engages the contact 82 tbs circuit will be completed tbrongb the erm'83, the plate to end tbe rotiis to which it connection 9?, beck to the negative terminal of tlie bette The current will then llTlOW EDYOLB. the battery to the corresponding nongnet, from the magnet through the conductor and ceble 9% end the contect 82, back to thev battery, When the dial and antenna hove once been arranged in proper relation tocecli other it will be epperent that the position of tbe diel will olweys indicate the position of the ontenne since the two will always move in unison with one enotbcn The entenne is held egeinst movement by external force and can only be moved vvbenopersted tbrongbrotstion of tbe dielc Any movescent of the dial will cense s. corresponding rotation oi tbe sntenns so long es current is W sop lied from the source of supply.
renged to enter openings 102 in the sten vvbeel 67. One opening 18 provided for each of the points 69. Gnrrent is supplied to the mesnet $9 through c switch 1G3 having s pose-button 10% extending npvvsrdly through the casing 63. (lee terminal 0:? the switch 1% is connected tbrougb the cable 9% to the positive terminal of tbe lostter The other terminel of the switch is connected through the magnet 99 to the frame nlste F6 which, as explained bef0re,is connected to the negative terminel of the battery. When the push-button 194 is depressed the magnet 99 will e energized if tbs source or" current supply is operative. '"fiis will retract the plunger 106 and permit rotation of the starvvlieei 57. If for any reason the source of current supply is inoperative the pion er will not be retracted on depression of the button 104 so that the dial cannot be rotated until the source of current supply is restored. Tbis prevents rotation of the dial when the current is slant off,
in the form oi tbe invention sbovvn in Figs.
'1 to 6, inclusive, the antenna ccnbe rotated nesessi only through 180 so that there is no possibility of Winding the lead Wires about the mast of the entenne.
it will be apparent that the niecbsnism sbovrn es en lied to on entenns mast may be equally We 1 opplied to other rotary members to permit them to be adjusted from s remote control station. Frequently it is desirable to be able to regulate the receiver without the necessity of leaving ones position and going to the receiving set. The control switch may be pieced on e dining-room tsble or et an other desired osition remote from the receiving set and t e receiving set can be controlled es readily ss if the person were directly at the receiving cabinet.
The invention provides relatively simple end highly 'eficient meens for controlling an electric circuit by remote control. The remote cbnt-sol-diel consists of relatively few parts ivbicb, when operated, produce impulses in the circuit of e magnet to rotate a. member snob es s radio entenns.
Changes may be made in the form, constrnction, end arrangement of ports without departing from the spirit oi the invention or sacrificing any of its edvents es, and the right is hereby reserved to me c all such cbenges as fairly iell within tbe scope of the following" claims.
