Canada Application December 10.1w, Serial No. mass "-4 Ohlm. (on. 14-10) UNITE STATES PATENTIO'FFICE' This invention relates to new and useful improvements in radio apparatus and'more particularly to a novel tuning mechanism for radio receivers.
The principal object of the present invention is to provide a tuning mechanism for receivers wherein stations can be selected conveniently by observing their geographical location on a panel board whereon push rods are located at the geolil graphical locations of the broadcasting stations.
Another important object of the invention is to provide a remote tuner for radio receivers wherein push rods are employed for selecting the broadcasting stations.
Other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings: Figure 1 represents a front elevational view of go a radio receiver showing the remote control device in perspective and electrically connected with the receiver.
Figure 2 is an end elevational view of one of the push buttons.
Figure 3 is a vertical sectional view taken substantially on the line 3-4 of Figure 1.
Figure 4 is a cross sectional view taken substantially on the line 4-4 of Figure 8. v Figure 5 is a longitudinal sectional view through the rack and gear means on the receiver.
Referring to the drawings wherein like numerals designate like parts. it can be seen in Figure 1 that numeral I generally refers to a conventional receiver having the tuning dial I through which the tuning shaft I extends. On this tuning shaft I (see Figure 5) is located the gear I which meshes with the rack 9 slidable through the guide structure ll. Thisguide structure II is provided with an opening II in the bottom thereof through which the gear 8 extends.
Extending from the rack 8 is the elongated rod I! which connects to the flexible shaft I! extending through the conduit It to the selecting mechanism generally referred to by numeral I i. In
the receiver l is the volume control unit II which has the flexible shaft i'l extending therefrom and through the conduit It to the selecting device II.
The selecting device II consists of the case made up of the back wall ll, short front wall 2|. bottom wall 2|, top wall 22 and end wall 23. Extending from the top of the short front wall to the top 22 is the inclined pane It on which is a representa tion of a map as denoted by numeral 28 in Figure 1. At important locations. that is, geographical locations on this map and where important it to connect as at SI to the plate 21.
broadcast stations are located, openings are formed in the panel 24 through which push rods 2! extend. It will be observed in Figure 3, that these push rods are all of different lengths. In other words, each station has a push rod of a 5 different length from any other station push rods and all of these push rods extend from the slidable plate 21 located at the inside of the case and which is located entirely behind the map 25.
Rearwardly of the plate 11 is the plate 28 in-' 10 clined in the same manner as the plate 21, but fixed to the back wall it by suitable brackets 29 and SI. Extending forwardly from this inclined plate 28 is the guide structure 3| within which the guide block 32 is slidable, this block 32 being i of polygonal cross section as is the guide 3i and preferably formed integral with or otherwise secured to the plate 21. The plate 28 is provided with the tubular formation 33 through which the conduit 14 extends and this carries a set screw :4 n which is driven against the conduit II to properly secure this end of the conduit to the plate 28. The flexible shaft it extends through this condui Each of the push rods II is provided with an identification plate It at the outer end thereof (see Figure 2) Obviously the push rods it are forced inwardly depending upon the station selected and the plate so 21 will only be moved as far as the push rod is forced inwardly and consequently the shaft it will always bemoved in accordance with. the
length of the push rod 2 to the end that the rack s will be moved a certain distance in rotating as the shaft 1 in order that the same action is obtained as when a radio receiveris manually operated in tuning at the receiver.
Suitable illuminating means 81 can be provided fisiiie case to illuminate the panel 24 from the 40 The tuning shaft i1 is controlled-by the knob ll on the wall II, and in the event the reception is not clear when selection is made by one of the buttons 2', the plunger II can be operated for 46 further adjusting the plate I]. The plunger 8! operates the rocker ll which is connected by the arm CI to the plate 21, the rocker being mounted on the bracket 42.
While the foregoing specification sets forth the 50 invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Z. The combination with the tuning unit of a radio receiver, of means to operate said unit to tune in different broadcasting stations selectively comprising a casing having a front panel aperturecl at dififerent locations thereon, a plate mounted in said casing behind said panel for movement in different degrees into difierent set positions to tune in diiferent stations, 2, flexible shaft operatively connecting said plate to said unit for operation of the unit in correspondence with the degrees of movement of the plate, a pinrality of push rods oi difierent lengths operative in said apertures to move said plate in difierent degrees respectively, and manipulative means for moving said piate'independently of said rods.
3. The combination with the tuning unit of a radio receiver, ot means to operate said unit to tune in different broadcasting stations selectively v comprising a casing having a front panel apertured at different locations thereon, a plate mounted. in said casing behind said ,panel'for movement in difierent degrees into diflerent set positions to tune in diflerent stations, a flexible shaft operatively connecting said plate to said unit for operation of the unit in correspondence with the degrees of movement of the plate, a plurality of push rods of difierent lengths operative insaid apertures to move said plate in difierent degrees respectively, and manipulative means for moving said plate independently of said rods comprising a rocker mounted in said casing and operatively connected to the plate, and a plunger slidably mounted in said panel and operatively connected to the rocker.
