REMOTE CONTROL FOR RADIO APPARATUS Filed Aug. 51, 1953 gWM-wm/ MW Q Patented Ar. 7, 1936 STATES PATENT OFFICE 7 2,036,948 REMOTE CONTROL FOR RADIO APPARATUS Joseph Orris McNary, Anacortes, Wash.
Application August 31, 1933, Serial No. 687,696
3 Claims. (01. 250-40) This invention relates to a remote control for radio apparatus and has for an object to provide an improved remote control mechanism suitable for attachment to any radio set so as to enable the radio set to be controlled from a distance.
A further object of this invention is to provide a remote control mechanism for radio apparatus which makes it possible for the dials of a radio set to be manipulated from a convenient dis tance from the radio receiver, as for instance by a person seated in a chair beyond arms length from the radio receiver.
Still a further object of this invention is to provide a remote control radio mechanism which is operable somewhat beside the position straight in front of the radio receiver, so that it is not, necessary to be seated directly in front of the radio receiver in order to control the latter.
With the foregoing and other objects in view, as will hereinafter become apparent, this invention comprises the constructions, combinations, and arrangements of parts, hereinafter set forth, claimed and illustrated in the accompanying drawing:
Fig. 1 is a perspective view of the invention applied to a radio receiver.
Fig. 2 is a fragmentary plan view of the right hand end of one of the control rods.
Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2.
Fig. l is a modification of the invention showing a support for the control rod and the universal coupling on the opposite end of the rod.
Fig. 5 is a View showing another method of fastening the control rods to the radio receiver.
There is shown at It a conventional representation of a radio receiver provided with the usual control knobs Il, I2 and I3. Knob II! may be used for turning the said radio receiver on and off, while knob I2 is used for selecting the station and knob I3 for controlling the volume.
As shown in Figure 1, a remote control mechanism M is applied to each of knobs I2 and I3 and if desired, another similar mechanism can likewise be applied to knob II. Inasmuch as each control mechanism I4 is identical, only one of them will be described, this remote control mechanism constituting this invention.
The remote control mechanism I4 consists of a rod I5 having at one end a ball or handle 16 for easy manipulation thereof. The rod I5 may be of any suitable length and is connected to a short length II by means of a universal coupling I8. The coupling I8 may be of any desired construction, the form herein shown comprising a ball Iii formed on the end of the short length I! and a socket ZI] formed on the end of the long rod I5 and having a connecting pin 2| passing through opening 22 in the ball I9.
The short length I"! ends in a bridge 22 through whose legs 23 are bored thumb screws 24. The bridge 22 is of width somewhat wider than the diameter of a radio receiver knob allowing the thumb screws 24 to securely fit the opposite sides of the knob I2 and hold the remote control mechanism It in position on the knob.
The form of the invention just described especially intended for use where the operator would be located substantially in front of the radio receiver IE], but as quite often happens, it may be desirable to control the radio receiver Ill from a position other than directly in front thereof. In this form the rod I5, instead of being provided with a handle or ball at the outer end, is provided with another universal coupling I8 which connects it to another length of rod 25 and a handle 26.
The rod I5 is provided with the same universal coupling I8 and the same type of mechanism for connecting the short length II to the radio receiver control knob. An adjustable support 2'! carries the weight of the end of the rod I5. The support 21 consists of 'a supporting sleeve 28 and a telescoping rod 29 secured at the desired height by means of a thumb screw 30. The upper end of the supporting rod 29 is provided with a supporting tube 3I through which the rod I5 may be rotated as desired for manipulating the radio control knob. With this mechanism as shown at I4, the rod I5 may be set at an angle to the short length II and the rod 25 may be set at a further angle to the rod I5, enabling the radio II] to be controlled from a position other than directly in front thereof.
Instead of securing the short length N to the radio control knob by means of a bridge and thumb screws, many other suitable securing means may be provided. Thus, as shown in Figure 5, the length II is provided with a bifurcated end H. The fingers 32 and 33 formed of this bifurcated end 3| are placed on opposite sides of the knobs I2. The length II is threaded as at 34 adjacent the bifurcated end 3| and a threaded sleeve 35 cooperating therewith tends to draw the fingers 32 and 33 toward each other and securely grip and hold the radio control knob I2.
The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed and that any change may be made therein within the scope of what is claimed Without departing from the spirit of this invention.
Having thus set forth and disclosed the nature of this invention, What is claimed is:
1. For use With a home radio receiving apparatus of the type having at least one radio control knob on one face thereof; the combination with said radio control knob of a quick attachable remote control mechanism for operating said control knob from a distance comprising a plurality of rods, ball and socket universal coupling means securing said rods together, and means at the end of one of said rods detachably securing said mechanism to said radio control knob, said securing means comprising a bridge, forwardly but angularly extending lugs on said bridge to fit over said radio control knob, screw means threaded through each of said lugs to detachably secure said bridge to said knob and a telescopic sleeve and rod for operatively supporting an intermediate rod.
2. For use with a home radio receiving apparatus of the type having at least one radio control knob on one face thereof; the combination With said radio control knob of a quick attachable remote control mechanism for operating said control knob from a distance comprising a plurality of rods, a plurality of ball and socket universal coupling means securing said plurality of rods together, means for securing an end rod of said plurality of rods to said radio control knob, a ball handle means on the other end rod, and an adjustable telescopic sleeve and rod supporting means for an intermediate rod.
3. For use With a home radio receiving apparatus of the type having at least one radio control knob on one face thereof, the combination with said radio control knob of a quick attachable remote control mechanism for operating said control knob from a distance comprising a train of rods, ball and socket universal coupling means securing said train of rods together, means for securing one end of said train of rods to said control knob of the radio receiver, a manual ball handle at the other end of said train of rods, and telescopic sleeve and rod means for rotatably and adjustably supporting an intermediate portion of said train of rods.
