Another object'of my invention is to 4providea new and improvedl stereoscopic television apparatus which is simpler, cheaper, moreeiiieient known. Y
Another object'of myvinvention is to provide a new and improved stereoscopic televisionapparatus wherein the image creating mechanism ismounted in a spectacle frame.
Other objects and advantages will paratus as the description proceeds.'
In the drawing: Fig. 1 isa-partly diagrammatic view of the re.
ceiving apparatus of my invention; Fig. 2 is altransversa'sectional the line 2-2 of Fig. 1: and
Fig. 3 isv a diagrammatic view showingfthe sending apparatus and its positional relationship In Fig. 3. I have indicated a pair of television cameras I Il and [2.as-being focused on anobj'ect i4 to be televised. The robject I4 is alternately viewed by the cameras I and I2 andthese cam- -eras are connectedy to a conventional transmitter view taken on Vand with equal facility view anobject which hass y and moreA convenient than'` those heretofore attached.' to' the ends of the subframe 38 andare `adapted to have theircurved ends positioned back of the spectators ears to prevent the frame from slipping' oil. of his nose and accurately to position c `thelenseslland 44 infront of his eyes. -The subframe 38 has a pair of forward extensions 50 and 52 to whichare attached. the legs 54 and 56,
of a second subframe 58. illustrated as being com- Vposed of. sheet metal strips, although it'rnay be made of any other suitable material. The sub.- frame nhassp'ring iinger's 60 which support and holdth'e cathode ray tubes in axial alignment with the magnifyinglenses 42 and 44.. The Isubframes are adjustably connected by screws 55 and become lapi 51 passing through slots in legs 54 and 5G where-A by the distance between the lenses and tubesmay be varied. Y
' A feature of my invention lies in the fact thatl lthe cathode raytubes 32'and 34 may be extremely small;4 thatlis, approximately one inch. in diameter.` Such tubes are relatively inexpensive and are lightjin weight so that they can be readily mounted in a spectacle frame as shown inthe drawing.. The lenses 42 and 44 maybe of'inexpensive construction. The arrangement of the `lcathode-ray tubes and the convex magnifying I6 through an electronic. 'switching device -I8 in such fashion -that the switchlng'device feeds tb s the transmitter images alternately =taken from the two cameras. This switching device also sendsa synchronizing impulse which is broadcast bythe transmitter. T he transmitter I6 is shown a conventional broadcast The waves 'broadcast from the aeriall 2lir ofthe transmitter4 i6 are 4picked up by the aerial 22 oi a receiver 24 whichpassesthe receivedsignai to Vthe two separate images signalsunder the con,- trol of the synchronizing impulse from the transmitter. VTheseparate image signals are then passed through aflexiblecable containing wires 28'and 30 leading to twosmall vcathoderaytubes 32 and 34 which aresupp'orted in a spectacle frame indicated generally by reference charac#v an electron-ic switching device 26 which separates lenses is'such that only-one cathode ray tube is seen with each eye and itis unnecessary to' p roi .vide a partition between the two tubes to` prevent' eacheye from seeing both tubes.
' Where the viewing Vspectacles are tobe used by a person who ordinarily wears glasses," the frame4 36 will, ordinarily be so designed that it can be placed on' thespectators nose beyond but in alignment with his vision correcting glasses,
If desired, however, the magnifying lenses 42 and 44, can-be. ground to provide both the necessary magnification and vision correction and under these conditions the usual eye glasses will be 'removed before the frame 36 is positioned on the face.
My novel. spectacle frame viewing apparatus isf.
simple -and inexpensive and insures the most perfect positional relationship between the wearers eyes and the images being viewed. Furthermore.
i- 'it permitsthe spectator -tofrecline in a comfortable chair andto view the object being televised Without 'sitting insome certain position relative to a screen or other xed surface upon which the imagesai-eshown. My invention also has the further advantage that several viewing spectacles may be' connectedin parallelto the lsame plastic subframe 38 having a bridge. or ynosepie'ce I fand mounting -a pair of convex magnifying 48' arev pivotally switch'device'26. In Fig. 1 of'the drawing, I
have indicated this by showing additional cables 3 2 and' 64 rleading to other vspectacle receivers which are not shown but which may be identical with that shown in Fig. 1.
While I have illustrated and described in detail only a single embodiment of my invention,
it is to be understood that my invention may assume numerous other forms and that my invention includes al1 variations and modications falling within the scope of the appended claims. I claim:
1. stereoscopic television apparatus o! the class described, comprising a spectacle frame, a pair of magnifying lenses mounted in said frame,'and a pair of image creating tubes* mounted in said frame in alignment with said lenses.
2. stereoscopic televisionapparatus of the class described, comprising a rst subframe, including a nose support and magnifying lenses mounted therein on opposite sides of said support. a second subframe attached to said rst subframe, a pair o: small cathode ray tubes resiiiently mounted in said secondsubframe and bows pivotally attached to one of said subframes.
4. Apparatus of the class described, comprising a plastic frame and having a nosepiece, lenses mounted therein on opposite sides of said nosepiece, bows attached to said plastic frame, a second frame attached to said plastic frame, image forming tubes mounted in said second frame, each of said tubes being in alignment with one of said lenses, and means for varying the distance between said frames.
