UNITED STATES PATENT OFFICE.
BILLBOARD RADIO PICTURE RECEIVER.
Application filed. June 5, 1925, Serial No. 35,117. Renewed September 10, 1926.
This invention relates to apparatus for receiving radio pictures of the-pen-and-ink type, and has for its principal object means for carrying an inking supply over a large picture surface and for controlling the flow of ink to said surface.
With this and other objects in view, the invention consists in the novel details of assembly of the various elements employed,
hereinafter disclosed, and particularly pointed out in the claims.
In the drawings Fig. 1 is an easel-sup ported picture-receiving surface over which a marking-pen arm sweeps; Fig. 2 a top view of a picture-sending machine; and Figs. 3, 4 and 5 detail views.
In all figures, like symbols refer to like parts, in which A is a picture surface; B a support therefor; C an arm which sweeps over the picture surface; D a shaft upon which the arm is mounted E a slotted arm fastened to shaft D, to give reciprocating motion to the arm C, by reason of the engagement in the slot of a pin F in the face of the gear G which is rotated by the motor H.
The paper A (or other surface, Fig. 2)
upon which the picture is, is moved forward.
a step at a time b engagement therewith of the spur wheels upon which the paper is held by the elastic chps K; the spur wheels being given a step-by-step motion by reason of the rotation of the ratchet Wheel L and pawl and connecting rod L.
In the hole in the moving end of arm C in Fig. 2 a two-point pen, Fig. 5, is mounted; and when so mounted is caused to sweep, across the ink picture, which, being of electric current conducting material, short-circuits the pen points, sending an electric impulse through wires W to the radio transmitter S. The duration of the impulse is proportionate to the'length of contact of the pen with the ink figure. The process is Y now well known in the art.
On the upper, moving end of the arm C, Fig. 1, is mounted an ink well C, shown in above the paper and the ink sprayed on by air under pressure, entering through the tube Q, a method well known.
The box X, Fig. 1, contains a motor and mechanism similar to that shown in Fig. 3, for oscillating the arm C. But instead of moving. the paper up, as in the sending tablet machine, Fig. 2, the mechanism-containing box X moves down, with its pen arm C, by the intermittent, partial rotation of gears Y engaging the rack Z.
What I claim is- 1. In a picture-receiving mechanism, the combination of a picture-receiving surface, an ink-fountain carrying arm, means for sweeping the arm over said picture surface, means for producing an air pressure in said ink fountain, means for releasing ink from said fountain, and means for 'pre-determining the order of the ink release.
2. In a picture-receiving mechanism, the
combination of a picture-receiving surface, an ink-fountain carrying arm, means for sweeping the arm over said picture surface, means for displacing the arm and its operating means with respect to said receiving surface, means for releasing ink from said fountain, means for producingair pressure in said fountain, and means for pre-determining the order of the ink release.
In testimony whereof I have aflixed my signature.
CHARLES FRANCIS JENKINS.
