WILHELM vox SIEMENS, 0F CHARLOTTENBURG, NEAR BERLIN, GERMANY, ASSIGNOR Tb SIEMENS & HALSKE, AKTIENGESELLSGHAFT, 0F BERLIN, GERMANY, A CORPORA- TION OF GERMANY.
TYPE-WRITER.
To all whom it may concern:
Be it known that I, WILHELM VON Sm- MnNs, a citizen of the German Empire, and residing at Charlottenburg, near Berlin, Germany, have invented certain new and useful Improvements in Type-Writers, of which the following is a specification.
This invention relates to typewriters, and a primary object is to provide an improved typewriter adapted to produce prmted matter of a good quality at a very high speed.
To th1s end, in the improvedtypewriter type images are thrown by means of stationary templets onto a surface sensitive to light. The time which each image lasts may be so short that the Sensitive surface onto which the type images are thrown may move continuously and need not be stopped at all. In this case the sensitive surface will move at a uniform speed during the production of a whole line, and the jerks which are otherwise produced by stopping the heavy paper carriage are avoided;
Another object is to provide that each letter may be produced at a center-distance from the last previously printed letter corresponding to its characteristic breadth. To this end, the images are produced at various intervals of time, so that for example, abroad image is thrown onto the sensitive surface only when the latter has been fed a distance corresponding to its breadth. In
order that each image of a type may be produced at the correct moment the exposures are controlled in the improved typewriter by a register band. This enables printed matter to be produced at a speed which cannot be attained by a manual operator however dextrous.
To these and other ends the invention consists in the construction, arrangement and combination of parts described hereinafter and pointed out in the claims.
One illustrative embodiment of the invention is diagrammatically represented by way of example in the accompanying drawing, wherein Figure 1 is a diagram showing the general arrangement of the s ark gaps, lenses and screen provided wit type templets and suitably related to the material to be printed upon;
Fig. 2 shows means'for making the movement of the sensitive surface dependent on that of the register band;
Specification of Letters Patent. Patented Sept, 30, 1919 Application filed November 26, 1915. Serial No. 63,569.
gig. 3 shows a portion of a register band, an
Fig. 4 is a diagram showing means for recharging the condensers.
Referring to Fig. 1, the material 1 to be printed upon, e. 9., sensitized paper, is wound about the platen 32 of the paper-carriage 33. Type templets 2 are arranged in the screen 3 located behind the platen, and behind each templet is arranged a spark gap 4:; the light from these spark gaps is thrown by the lenses 5 and 6 and the prisms 7 onto the same point in the path of movement of the sensitive surface.
The operation of the spark gaps is controlled by a register band such as that represented in Fig. 3. The illustrative embodifor each type. The round guide holes 12 are I for holding the register band in place and for feeding it. The band 9 runs over a contact block 10 (Figs. 1 and 2), on which nine contact springs 11 bear. When one of the square holes 13 passes under one of the contact springsthe following circuit in-Fig.
a spark gap 4, a contact sprin 11, the contact block 10 and the other p0 e of the condenser. The condenser discharges and produces in the spark gap a spark which throws an instantaneous image of the type onto the sensitive surface 1.
The movement of the sensitive surface 1 and that of the register band 9 are dependent on one another. As shown in Fig. 2, the band 9 is wound on a roller 17 A guide roll 16 carrying pins 16 which take into the holes 12 feeds the band between the contact block 10 and the springs 11; a roller 18 winds the band up. The guide roll 16 is geared by means of the gear wheel 15 with the toothed rack 14 of the paper carriage 33 on which the platen 32 is mounted. The sensitive surface 1 carried by the paper carriage and the register band consequently move at speeds proportional to one another.
The holes 13 of the register band are various distances apart in the longitudinal direc tion, as Fig. 3 shows. For example, the first two holes 13 are just as far apart as two '85 1 is closed, viz :one -pole of a condenser 8,
Fig. 4 shows one form of apparatus for recharging a condenser. The circuit runs from one pole of the condenser 8 over the spark gap 4, the contact spring 11, the contact block 10 and then through a magnet 22 to the other pole of the condenser 8. As soon as the spring 11 closes the circuit the magnet 22 attracts the pawl 28 and rocks it into its outer position, this pawl being normally held in its inner position by the spring 29. The stop 27 on a disk 23 is thereby released by the pawl. The disk 23 is under the action of a tensioned spring 24, and whenever the electromagnet 22 is energized for a short time the disk 23 can rotate once. Thereby a contact piece 25 on the disk passes under two stationary springs 26 hearing on the disk 23, whereby the following charging circuit is closed, viz: one pole of the battery 21, the springs 26, the contact piece 25, the condenser 8 and the other pole of the battery 21. The time taken by the contact piece 25 to move as far as the springs 26 is made such that in the meantime the next perforated symbol 13 has moved forward underits contact spring 11.
The type templets 2 can be constituted simply by a photographic negative of the types. This is cheap to manufacture and the type templets can be readily and rapidly exchanged for others of different design.
Havin thus described in the foregoing some em odiments of my invention, I do not wish to be understood as limiting myself to the precise constructions as shown, since modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention. I therefore claim as new and desire to secure by Letters Patent of the United States 1.
