The projection lens device consists of a housing a frame 12 case 42, is eccentrically inserted in member within the housin an electric motor 13, a 48, and contains the projecting lens 49 and switch 14 for the niblor, a ground glass screen diaphragm 50. The image or picture formed 50 15 on which the picture or image received is by the projecting lens 49, is thrown upon the andprojecting cylinders, I provide an electric motor 13, provided with a shaft 51, on which are mounted the spur gear wheels 52 and 53. Spur gear wheel 52 drives pinion 54, on a countershaft 55, and ear wheel 53-drives pinion 56, on a counters iaft 57. Countershaft 55 has mounted thereon a. gear wheel 58', adapted to drive gear pinion 59, integral with impressing cylinder rotatable member 35, andcountcrshaft 57 has mounted thereon agear wheel 60. adapted to drive gear pinion 61, integralwith impressing cylinder rotata ble member 62. The projecting cylinder members have integral worm gears 68 and 64, driven respectively, by worm pinions 65 and 66, respectively on shafts 67 and 68.

' driven respectively, by miter gears 69 and 7 O. The projecting cylinders are rotated by the gear mechanism at a high speed of revolution, and theimpressing cylinders are r0- tated at a much higher speed of revolution. Bin-ding posts 71, are provided for the motor, therebeing an electric conductor wire 72, leading from a binding post 71, to switch 14, a wire 73, leading from switch 14 to the motor, and a wire 74, from the motorto the remaining binding post 71.

For energizing the photo-ce1l, I provide a binding post .75, and a wire leading therefrom to switch 76, a wire 77, from switch 76 to binding screwv 29. The energizing current then passes to the'photo-cell and thence to the binding post 28. This circuit controls the cell '17. The neon lamp 16 is-controlled in an similar manner, for which I provide binding post 78. and a wire leading therefrom to switch 79, awire 80, from switch 79 to a binding screw 81,.the circuit continuing through the neon lamp and thence to binding post 82. ,Each energizing circuit for an elcctriccell, is independentlyl controlled by a switch, allowing the operator to cut out either the receiving or transmitting elements, orboth.

,7 Referring to the diagram as shownin Fig. 6, the television device is shown in connectionwith atelephone system, and includes telephones 83, switch board 84, ground connections 85, for the telephones, and line wires 86 and 87 The television apparatus includes the radio transmitters 88, the amplig 'fiers 89 for the transmitters,the amplifiers 90, "for the receivers, and the television de vices which form the subject of this invention. The motor is energized. by terminals 91, froma source of electric energy. a

In use, the motors of the transmitting and receiving devices are started inmotion. As-

suming an object to be in front of the television device, the transmitting lens will scan the object or picture to be transmitted, and

will project the light therefrom to the adjacent in'ipressing cylinder. The projected light is then passed through the very small aperture and thence through the adjacent cylinder prism, where it is transposed and projected through the conical chamber and into the lens ot'the adjacent photo-electric cell. Through the action of the light on this photo-electric cell, there is generated electrical impulses, which pass to power amplifier 89. and then projected, as shown in the be used for projecting motion pictures on a much larger screen. All supporting elements are of relatively thick metal, to attain precision of operation and efit'ective results.

This device may be used in combination with a telephone exchange system, or with radio, wireless, wire-Wireless, three wire phone system, twowire telephone system, or other suitable electrical transmitting means. In any wire system, the television devices operate, and do not interfere with the working of the telephone system.
