REMOTE conmor. FOR TELEVISION AND RADIO APPARATUS Filed May 24, 1954 V INVENTOR. DOME NICK 4-H SAUSOTT H United States Patent D REMOTE CONTROL FOR TELEVISION AND RADIG APPARATUS Domenick A. M. Sansotta, Pittsburgh, Pa.
Application May 24, 1954, Serial No. 431,713
1 Claim. (Cl. 179--1) This invention relates to a remote control device, and while primarily intended for use in connection with a television receiving apparatus because of the fact that the cost of the latter usually precludes having more than one such apparatus in the ordinary home, it will be obvious that the device may be employed in connection with radio receivers, phonographs, or any other type of sound reproduction apparatus wherein it is found to be applicable.
Important object and advantages of the invention are to provide a remote control device of the character described which aifords efficient means for receiving and controlling the transmitted sounds at locations remote from the location of the television receiving apparatus to which it is connected, which may be readily attached to a conventional type of television apparatus without requiring any changes to the construction and arrangement of the latter, which may be used and operated independently of the loud speaker of the television apparatus or simultaneously with the loud speaker, and which may be readily constructed to accommodate any desired number of listeners at the remote location.
Further objects of the invention are to provide a device of the class stated, which may be attached to a television apparatus by any one of ordinary skill, which is simple in its construction and arrangement, compact, positive in its action, and comparatively economical in its manufacture, installation and maintenance.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing, but it is to be understood that changes in the form, proportions and details of construction may be resorted to that come within the scope of the claim hereunto appended.
In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:
Figure'l is a diagrammatic View illustrating one arrangement of the electrical circuits employed in the operation of the remote control device.
Figure 2 is a front elevational view of the portable control box embodied in the invention.
Figure 3 is an end elevational view of the control box.
Figure 4 is a plan view of a headphone used in connection with the remote control device.
Figure 5 is a top plan view of a special plug element employed when the remote control device is disconnected from its attachment with the television receiving apparatus.
Referring in detail to the drawing 1 and 2 respectively designate the loud speaker mechanism and the tuner mechanism of a conventional television receiving apparatus 3. Usually the speaker and tuner mechanisms are joined by a pair of electrical conductors, which are attached to the speaker mechanism and have a detachable socket connection with the associated tuner mechanism.
In the present invention, the pair of conductors 4 and 5 that are attached to the speaker mechanism 1 and the 2,835 13 Patented May" 20, 1958 pair of conductors 6 and 7 that are attached to the plugin socket 8 connecting with the audio output circuit of the tuner mechanism 2, instead of being joined together in the usual manner respectively connect with. a four hole socket block 9. The socket block 9 is preferably rigidly attached at any suitable position to the television receiving apparatus 3.
Parts of the electric circuits incorporated in the remote control device, together with associated control elements, are housed in and carried by a suitably small portable control box 10 which includes a front panel 11.
A flexible extension cable 12 of any required length is provided for joining the television receiving apparatus 3 with the control box 10 and embodies four separate conductors, respectively indicated at 13, 14, 15, and 16, which have their ends connected with respective plug blocks 17 and 18. The plug block 17 has a detachable plugged-in attachment with the socket block 9 which is carried by the television receiving apparatus 3, and the plug block 18 has a plugged-in attachment with an adapted socket block 19 which is preferably rigidly attached to the back wall 20 of the control box 10.
It is evident that when the plug blocks 17 and 13 are engaged in respective socket blocks 9 and 19, the speaker mechanism 1 and the tuner mechanism 2 are joined with the control box 10 to connect with the various operating circuits that are mounted within the control box and which connect with the socket block 19.
The speaker circuit consists of the conductor 20 connecting with the socket block 19, the double pole switch 21, conductors 22,23, 24, rheostat 25 , conductors 26, 27, 28, the double pole switch 21, and the conductor 29 connecting with the socket block 19.
The tuner circuit consists of the conductor 39 connecting with the socket block 19, conductors .23, 24, rheostat 25, conductors 26, 27, and the conductor 31 connecting with the socket block 19.
The headphone circuit consists of the conductors 30, 23, 32, the single pole switch 33, and conductors 34 and 35 to the headphone sockets 36, and the conductors 31, 27 and 37 to the headphone sockets 38, with the conductors 24 and 26 connecting the rheostat 25 in the headphone circuit. The sockets 36 and 38 are aligned in pairs with each pair being adapted to engage a conventional two prong type of plug 39 that is connected with the headphone 40.
It will be evident that any desired number of such associated pairs of headphone sockets 36 and 38 may be connected in the headphone circuit to adapt the remote control device for use by a corresponding number of individual headphones. Further, sockets 41, adapted to be engaged by tip jack types of connecting plugs, may be connected in the head phone circuit if desired.
The headphone 40 may be of the conventional construction now in common use, or may be constructed to embody a sound volume control 42 for the headphone and with an individual control switch 43.
A suitable interconnected four prong plug 44 is employed for engagement in the socket block 9 to join the conductors 4 and 5 with respective conductors 6 and 7 to restore the television receiving apparatus for use in the ordinary manner when the remote control device is detached from the socket block 9.
The switches 21 and 33, the rheostat 25, and the sockets 36, 38, and 40 are all mounted on the box front panel 11 in a manner to allow the use of and permit adjusting operations of these elements from the outer face of the box panel.
In practice, the use of the improved remote control device is as follows: The plug blocks 17 and 18 are engaged in respective socket blocks 9 and 19, whereby the television receiving apparatus 1 is attached to the conparatus 3 is switched on, and the tuner mechanism 2 is adjusted in the usual manner to provide the desired sound volume through the speaker mechanism 1. Assuming that the headphone 40' is plugged into an associated pair of sockets 36, 38, and if the switch 33 is closed, sound reception will be had through both the speaker mechanism 1 in the usual manner and through the headphone 40. By opening the double pole switch 21, the speaker mechanism 1 is silenced, but sound reception will be had through the headphone.
By the adjustment of the rheostat 25, the sound volume through both the speaker mechanism 1 and through the headphone 40 may be controlled within the limits of the sound volume to which the tuner, mechanism 2 has been originally adjusted at the television receiving apparatus. In other words, the rheostat 25 may be ad lusted to decrease the sound volume of the speaker mechanism 1 and of the headphone 40, but will not function to increase the sound volume beyond the volume to which the tuner mechanism 2 has been previously adjusted.
The most important and novel feature of the invention is the provision of the described remote control device that may be selectively employed to independently regulate the sound volume of the speaker mechanism 1, within the limits above stated, at locations remote from the location of the television receiving apparatus, or to simultaneously operate and control the speaker mechanism and the headphone, or to silence the speaker mechanism 1 completely and operate and control the headphone independently of the speaker mechanism 1. When the remote control device is disconnected from the television receiving apparatus, the latter is restored for use in the conventional manner by the use of the plug block 44 as herein stated.
The present invention provides a most eflficient device of its kind, which may be economically constructed, and
4 successfully employed for the purposes and in the manner herein set forth.
