March 2, 1937. c. J. ZIGLER A RAIDIO CIRCUIT ACT'JATING DEVICE Filed July 15, 1932 Patented Mar. 2, 1937 UNITED STATES PATENT OFFICE RADIO CIRCUIT ACTUATING DEVICE Delaware Application July 13, 1932, Serial No. 622,269
6 Claims.
My invention has a general application but is particularly adapted to actuate an integral formed automobile radio receiver, whereby the many disadvantages of the present day radio receiver structure are eliminated. It is commonly known that to use the present day radio apparatus in a power driven vehicle, as an automobile, said apparatus must be installed in separate locations which occupy more room than is practically available, apparatus thus installed must be electrically and mechanically communicated wth unsightly and complicated Wires and cables which not only are a detriment to good radio reception but also create hazards that are known to have caused injury to people both in and out of the vehicle in which they are installed. The radio loud speaker as it is now installed in a vehicle is remote from the place of natural sound delivery.
With my improved structure all apparatus is arranged in integral form, is substantial and compact and may be installed adjustably in a minimum of space which is always available, all unsightly wires (cables being unnecessary) that communicate the various parts and create hazards are dispensed with.
'I'he operating controls of my actuator are reduced to a minimum in one location and are safe and convenient to operate, the radio loud speaker is brought forward caused to register with and be bailled by the control panel of the vehicle in which it is installed, thereby placing the speaker for natural sound delivery, I may however install the unit structure and provide a baille member integral with the structure, the integral baille attached to the loud speaker of said actuator is used when it is not convenient to provide the baffle in the control panel of the vehicle, however the separate integral baille will perform the same function in controling the air current generated by the movement of the loud speaker cone as the control panel baille shown at 20 Fig. 2.
Applying my improved actuator to a radio receiver circuit depends greatly on the mechanical application of a radio speaker field magnet, said magnet being caused to function mechanically as well as magnetically, by doing so a most compact, rigid and accurate actuator is produced, to accomplish this desired result I provide a speaker field magnet in tubular form, I also provide operating shafts in concentric form, said shafts in concentric form are aligned with said magnet axis, caused to pass through and be movably supported by the axis of said tubular field magnet, thus permitting the controls to be reduced to a minimum in one location.
It is well known to the magnetic art that a properly arranged tubular magnet may be magnetically saturated and become equally as efdcient as a magnet of the solid bar type, therefore I incorporate a tubular magnet as a component of my improved device. As the case demands I may provide the operating shafts that pass through the axis of said magnet of magnetic or non-magnetic material, when made of non-magnetic material it is obvious that said magnet can have no magnetic influence over said shafts and said shafts in no way can have armature characteristics with respect to said 15 magnet, when said shafts passing movably through the axis of said magnet are made of magnetic material one would naturally think vthat said shafts would become an armature with respect to said surrounding magnet, this however is not the case for experiments have shown that a magnetic member may be located to move within a magnetic mass and not become an armature with respect to said magnetic mass while in this location, therefore I may accomplish the desired result with shafts of magnetic or non-magnetic material, my improved actuator integrally formed is detailed in the following portion of the specification.
Fig. l is a partly broken away side elevation of the integral structure illustrating the adjusting means of communicating said integral structure with the control and motor panels of a vehicle.
Fig. 2 is a front elevation of the integral structure attached to a partly broken away control panel.
Fig. 3 is a plan view of the actuating members in assembly.
Fig. 4 is a plan of one of the two adjusting members.
Fig. 5 is a vertical sectional view of the combination electric switch and volume control member looking into same from the condenser end.
Corresponding with the drawing I is a radio loud speaker of the dynamic type, said speaker having provided the tubular field magnet 2, 3 is a. radio circuit tuning condenser of the variable type, said condenser is secured to the magnet 2 by the nut 4, 5 is a combination radio circuit electric switch and volume control member which is secured to the condenser 3 by the nut 6; 1 is a tubular operating shaft of condenser 3, Within the condenser shaft 1 is the shaft 8 which is secured at one end to the switch and volume control mem- `ber 5; shafts 1 and 8 in their concentric form 55 movably pass through the axis of speaker eld magnet 2 and terminate slightly beyond the speaker cone 9 for the attachment of operating knobs I and Il; at I2 are shown the movable condenser plates of condenser 3 said plates being secured to shaft 1 by the set screws I3, riding against the condenser plates I2 at the hub thereof are the springs I4 which help to maintain a predetermined setting of plates I2 which are moved to tune a radio circuit; at I5 is shown attached to shaft 1 the small disc armature, said armature being under the iniiuence of a magnetic pole of magnet 2, may assist springs I4 to hold condenser plates I2 in a setting while shaft 8 is adjusted to electrically switch and adjust the volume of a radio circuit with member 5; I6 is a chassis member and is used to house the various circuit apparatus and wiring, said condenser 3 being electrically connected to said circuit by suitable wiring. At I1 are shown the mounting and aligning rods which are attached to chassis I6 by the screws I8 and the nuts I 9; at 29 is shown in section a control panel of an automobile; at 2| is shown the motor panel of an automobile, rods I1 at one end are secured to the control panel 29 by the screws 22 and at the other end rods I1 are threaded, pass through the motor panel 2I and are secured therein by the nuts 23; at 24 is shown elongated slots in rods I1, by the use of elongated slots 24 and the screws I8 and nuts I9 the radio speaker cone 9 of speaker I is aligned with control panel 20, at 25 is shown a wire mesh grille guard which is mounted between the speaker cone 9 and the panel 28 said screen grille guard 25 providing a means of protecting cone 9 from injury; at 26 the shafts 1 and 8 in their' telescopic form pass through the screen grille guard 25, said extension providing means for the attachment of knob I9 to shaft 1 and knob II to shaft 8; at 21 is shown an escutcheon or indicator dial window secured to screen guard 25 ;y
at 28 is shown the formed indicator point of escutcheon 21; at 29 is shown the station selector dial, said dial is secured to shaft 1 by the set screw 38,' at 3I is shown an electric pilot light and socket, said light adapted to illuminate dial 29.
32 is the external metal casing, mounted in casing 32 is the resistance strip 33, 34 is a rotatable metal arm which is secured at 35 to the rotatable shaft 36, at 31 is mounted on the arm 34 the metal pin which is secured at right angle to arm 34, at 38 is an insulating plate which also is 'secured to arm 34, 39 is a spring copper contact which is secured to insulating plate 38 and which has a sliding contact on resistance strip 33, 40 is an electric toggle switch secured to the casing 32 by the rivet 46, 4I is the pendulum toggle of switch 49, 42 is a spring mounted in switch 49 to actuate the electric contacts therein, 43 are terminal lugs to which are connected to the resistance strip 33 and a radio circuit, with the aid of plate 45 and screw 44 resistance strip 33 is secured in the casing 32.
To operate this combination electric switch and volume control member the shaft 36 is rotated in a clockwise direction, this movement of shaft 36 imparts movement to arm 34 in a clockwise direction likewise the metal pin 31 secured to arm 34 is moved in a clockwise direction, the pin 31 is caused to enter 4I the pendulum toggle of switch 40, a continued movement of pin 31 in a clockwise direction moves pendulum 4I in a counter- `clockwise direction, this movement of pendulum 4I places tension on spring 42, as the pin 31 continues to move in a clockwise direction the pendulum 4I is snapped out of the way in a counterclockwise direction with spring 42, this causes the switch contacts to close placing switch in the on position, the swinging over of the pendulum 4I now is out of the way and pin 31 may continue to move in a clockwise direction, this further movement of arm 34 now engages the copper contact 39 with the resistance strip 33, and with the movement of contact 39 on the resistance strip 33 the volume of a radio circuit connected to terminals 43 is controlled, now by rotating the shaft 36 in a counterclockwise direction with the shaft 36 the copper contact spring 39 first moves off the resistance strip 33 thereby reducing the volume of the circuit, then a continued movement of the arm 34 causes the metal switch pin 31 to enter the switch pendulum 4I in a counterclockwise direction and with a continued counterclockwise movement of the pin 31 the electric switch contact is broken and switch is now in the olf position.
Thus two radio circuit instrumentalities are operated with but one shaft.
To actuate a radio circuit that is located in chassis member I6, knob II is rotated in a clockwise direction which through the shaft 8 the electric switch of member 5 is closed to electrically energize the circuit, further movement of the knob I I electrically adjusts the volume of the circuit with the volume control of member 5, now the knob I 6 is rotated in either a clockwise or counter-clockwise direction and through the shaft 1 the station selector dial 29 and the variable condenser plates I2, are adjusted to tune the circuit located in chassis I6, with the circuit thus actuated the speaker cone 9 is caused to make a sound delivery through the screen guard 25 and the control panel 28.
