Patented Dec. 31, 1935 UNITED s'rATEs amazs soma PATENT oFFicE aaanmc Macnnm' Gustav ramka. Vienna, .sum-ia Application May 27,1829, sensi No. 888.480 m Austria my ao, ma

zaouums. wi. 25041.;)

to be instituted thereby effecting the reading of such characters or indications, and thus replace reading by a person.

In order to attain this object the arrangement w according to the present invention is provided with cells, in which the electric conductivity is varied by radiation. and with comparison devices which on the arrival of certain rays iniluencing the cells direct or control the corresponding op- 15 erations,

The invention can be utilized for controlling any desired machine, however it will be found very useful in connection with oiilce-machines, which heretofo're could be operated only by per- 20 sons who were able to read. Further the machine may be used for testing and counting securities, bank-notes and so forth and for controlling automatons and the like.

One of the modes of carrying out the present 25 invention is illustrated diagrammatically by way of example on the accompanying sheet of drawing in which:-

Fig. 1 shows a perspective view of one construction, and

30 Fig. 2 is a detail view.

The embodiment shown in Fig. 1 serves for controlling the counting mechanism of a calculating machine. The record or sheet I, provided with characters or the numerals for calculation,

35 is placed on a base or carrier 2 in such a manner, that the number to be read is dlsposed opposite the lens 3, the record being illuminated by a strong source of light 4. On the other side of the lens 3 a suitable distance away, is ar- 40 ranged a photo-electric cell 5, in front of which rotat-es a movable device such as a. wheel 6 constituting a portion of a comparison device, provided with stencil-recesses corresponding'to the numerals to 9. The stencil-recesses are of such 45 a size and are shaped according to the numerals and are distanced in such a manner from the lens 3 that for instance the` image of the numeral l exactly coincides with the stencil-recess as soon as the latter is dlsposed atlthe cor- 50 responding place. A contact wheel 'I, provided with nine contactknives 8 and supplied with current by way of a brush 9, is connected With the wheel 6. A`contact-spring III is arranged opposite the contact wheel in such a manner,

55 that the knives 8 establish electric connection during the rotation of the said contact A wire of an Operating circuit leads fromv the contact spring loto a conta'oi-magnet ,|2 which on being charged with current attracte the armature il and by way of a link ll forces a pawl IB against the action of a spring II into a toothed feed-wheel |1 and feeds forward the latter for the extent of a tooth. A number-wheel or number representing or manifesting wheel ll is connected with the feed-wheel Il and accordlnsly 10 is fed forward also the extent of one place. In the circuit of the photo-electric cell I are included a low frequency transfonner 88 and a relay-magnet IS, which controls the current SUP- ply of the brush 9., During the rotation of the wheel 6, rays of light will periodically pass to the cell l by way of the successive stencll-recesses of the wheel 8. The cell 5 is subiected to full light if a blank place'of the sheet I is dlsposed opposite the lens 8` 'However a numeral, for instance the numeral 1, does not completely fill the other stencil recesses as shown in Fig. 2 by way of example of the stencil-recess corresponding to the Figure 2. Therefore light of the white writing sheet still passes to the cell I. l However a minimum of illumination of the cell 5 will take place, as soon as the stencii-recess corresponding to the numeral to be read is disposed in front of the cell. The relay IO in the i' control eircuit 38 is adiusted to' this Ailluminatlen-minimum and allows the withdrawal of. its armature 2| by means of the action of the spring 20. In this way the contact member 22 is released and thus the current-supply to the brush 9 is interrupted. Supposing the numeral 1 is to be read off, a contact-knife 8 would already have passed the contact-spring Ill at the time of the release of the relay-armature 2| and the figurewheel |8 would have been fed forward for a unit by the generated current. The' eight following 40 'contact-knives 8 would remain inoperative, be-

cause the current-supply tov the brush 8 is interrupted. Supposing the numeral 3 is to be ,read .011, three contact-knives would have become 'operative the flgure-wheel would have been fed forward for three units. and so forth.

Two camsV 23 and 2| return ,the parts 2| and 22 into the initial position after each revolution of the wheel 8. i The wheel 0 with the numerals or other characters thereon, constitutes a movable search member or character-bearing comparison device in the path of the rays of radiant energy. With said device move the wheel 'I and itsv contact knives or blades 8, said parts 1, 8 constituting 56 a control means adapted to open or close. at the contact spring lt, a sap in the Operating circuit il which includes the work device or magnet i and also has another gap which is open or closed bythe relay armatura Ii, the latter thus constituting another control means or control device for the Operating circuit ii, which second control means is under the control' of the photoelectric cell or other ray-'Sensitive device The magnet |2 through its armatura it and the parts connected therewith, controls manifesting means constituted by the wheel ll. This wheel moves in step with the wheel 'i as long as the character on the wheel 'I struck by the radiant energy does not correspond to the character on the record, but when the two characters do correspond, the manifesting wheel i! stops owing to the interruption of the Operating circuit at 2|.

No separate source of current is required in the circuit of the photo-electric cell when the latter is of the type that generatesan electric current when exposed to light. When using a photo-electric cell of the other type. which does not generate a current but simply varies in resistance under the influence of variations ofv light, I would of course include a battery or other suitable Sourcev of current in said circuit.
