PATENT OFFICE.
OF WASHINGTON, DISTRICT OF COLUMBIA.
RADIO TABLET METHOD.
Application filed m 5,
This invention relates to the reception of pictures by radio, and has for its principal object a simple method and mechanism suitable for entertainment and instruction in the home.
It is believed to be obvious that the attractiveness of this form of entertainment and instruction consists very largely indeed in an arrangement which permits watching the whole of the incoming sketch as it is built up line by line, adding to the instruc-' tional value of the picture the fascination attractiveness of the mystery of it.
Topermit the incoming picture to be so I watched continuously as it is built up to completion, a flat and approximately stationary surface only may be employed, in order that the whole of the growing picture may be unobstructedly seen at all times.
This is accomplished by laying a sheet of flat paper on a table, and traversing it with an ink pen to build up the picture in successive parallel adjacent lines, the paper being imperceptibly advanced (perhaps 1/100 of an inch per second), the figure being made by incoming radio signals.
-None of the methods heretofore used or suggested, so far as applicant is aware, could possibly be so used, nor could they be made suitable for the purpose sought by applicant.
The principal object of this invention, therefore, is to provide means whereby the development of the picture may be watched under usual, every day conditions.
With this and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.
In the drawings Fig. 1 is a top view of the instrument; Fi 2 details of the driving mechanism inside under the top; and Fig. 3 an electrolytic pen for use therewith.
In Fig. 2 A. is a motor with a worm B engaging a gear 0. On the face of gear is a pin D, in a slot in the arm E. Arm E is mounted on a shaft F. In the short end of arm E a rod G is hooked, the opposite 9 end of which engages a ratchet H, on the shaft K. On the same shaft is a spur wheel M (and M in Fig. 1).
In Fig. 1 R is an arm, the larger end of which is fastened on the upper end of shaft F. The other end of the arm carries an electrolytic pen S. T is a sheet of paper,
1925. Serial No. 28,224.
which is held doWn by clips U and U ontothe spurs M and M I The electric pen (Fig. 3) is made of an insulating glass-body having therein a capillary bore. The pointed tip Y is of metal having an extension of the capillary bore therethrough. The top section which forms a small reservoir for an acidulated ink. .VVhen current passes through the ink from the cap to the tip ink is discharged onto the paper; but such dis charge instantly ceases when the current stops. The pen is connected to radio receiving set J.
In operation,'when the motor is put into rotation. the arm sweeps the electric pen across the paper in successive parallel adjacent lines, lines invisible except where ink flows from the pen point;
The paper is advanced with each return of the arm E, which, as explained above, through the rod G, the ratchet H, and rotates the spurs M and M, upon which the paper is pressed by the clips U and U As the pen inks the paper under the control of the incoming radio signals, it will be understood that if these radio .signals represent a pictorial figure at the sending station, then the inked lines on the paper will make up a figure the duplicate of that at the sending station.
Of course, I do not wish to limit myself to an electrolytic pen, nor to the particular means shown for moving the pen and paper.
It is the particular method of attaining the object sought which I wish to protect.
What I claim is 1. The combination'of a base having an extended fiat surface, a shaft rotatably mounted upon said base, an arm fixed to said shaft and adapted to swing over said surface, a marking device carried by the outer end of said arm and engaging said surface, a second arm secured to said shaft and being provided with an elongated slot,
G a rotatable element adjacent said second arm,
and a pin secured to said element at a point removed from the center of rotation and extending into the slot in said second arm whereby rotation of said element causes said arms and shaft to oscillate said shaft.
2. The combination of a base member havin an extended flat surface, an arm pivotal y supported by said base and adapted to swing over said surface,
about the axis of a blank sheet can Z is a sleeve-like cured to said shaft andadapted to swing over said surface, a blank sheet carried upon said surface, a marking device carried by the outer end of said arm and engaging said blank, a second arm secured to said shaft and being provided with an elongated slot, a rotatable element adjacent said second arm, a pin secured to said rotatable element at a point removed from the center of rotation and extending into said slot whereby rotation of said element causes said arms to oscillate about the axis of said shaft, a rotatable drive element for said blank, said drive element bein provided with a ratchet and pawl, and PM? connecting said second oscillating arm with said ratchet and pawl whereby said drive element is driven in stepby-step motion.
v4. An electrolytic pen comprising a rod of insulating materlal having a capillary bore,
a conducting tip on the lower end of said rod and having an extension of said bore therethrough, a conducting sleeve element mounted upon the upper end of said rod and forming a reservoir for acidulated ink, said conducting tip and sleeve constituting electric terminals whereby the flow of ink through said bore may be controlled by electric potential variations. I
In testimony. whereof I have afiixed my signature.
