PNEUMATIC TYPE-WRITER.

Specification of Letters Patent. 2

Patented April 17, 1906.

Apnlipation filed November 16,1903. Serial No. 181.292.

To all whom it may concern-.-

Be it known that I, MAxnnLIAN SoBLIK, a

subject of the King of Prussia, German Em writers; and the object of the same'is to pro' vide for means to stop the type-wheel before the typewill strike and to move'the papercarriage after the type has been printed.

Hitherto been known aving an intermittent type-wheel and causing the paper-carriage to be moved at the same time while the type was caused to strike against the paper; Such type-writer is describ.ed,forinstance, in the United States Patent No. 676,590. To get a perfectly neat print with this kind of arrange ment the movement of the piston-rod of typewheel and thetravelin of the paper-carriage ought to be erfectly a ike; but as in fact this will not be t e case the impressions made by the type will not appear to be clean and neat.

Now the object of'this invention is to provide for means that the type will not be worked upon before the type-wheel has been brought to a stop and the paper-carriage will not be caused to travel before the type has struck against the paper, thus producing a neat and clean print; I attain this object by the mechanism illustrated in the accompanying drawings, in whichf v Figure 1 is a vertical section through the machine. Fig. 2 is a top View, some parts being shown in a horizontal section. Fig. 3 to put in operation the type, and Fig. 4 shows the same while in operation. Figs. 5 and 6 show the to views of Figs. 3 and 4. Fig. 7 represents t 1e gearing mechanism, and Figs; 8 and 9 represent the striking arrangement of the types in different views.

Similar numerals refer to similar parts throughout the several views.

To the base-plate 1 is fixed avertical axle 2, having two longitudinal canals 3 and 4, the one of which, 3, leads to an air-compressor, (not shown in the accompanying drawings,)

while the canal 4 is connected with the cylin- Improvepneumatic type-writers have rotating an annular ring 9, that is arranged upon the base-plate 1 concentrically to the axle 2. The ring 9 is the number of which corresponds with the numbers of keys of the machine, eachhole to v have a separate pipe 11 leading to the mouth of the perforated key 12. The arm has an air-passage 13, theouter end of which is opposite the holes of the ring 9, while the upright part leads to the annular slot 14 of the sage 1s connected to another annularslot 16 of the casing 6, which slot 16 is permanently in connection with the passage 4, that leads to the high pr'essure cylinder.

The casing 6 carries a bevel-gear 17, that meshes the gear 19, fixed tothe'axle 18, which axle also carries a screw-wheel 20, engaging the worm-wheel 21,.to which is attached the rod 22; rod 24,: engages a screw-wheel 25, carried by anaxle 26. This axle 26 may be rotated by the rack 27 of the'paper-carriage 28, passing the gear. 29, fixed to the axle 26. Between the two Worm-wheels 21 and 23 and within the reach of the rods 22 and 24 is arranged a double lever, consisting of the one-armed le- 30, and of a. double-armed lever 33, movably attached thereto upon a verticalpin 32. The lever 31 rests upon the piston-rod of the aircylinder 5' and is held there by means of a spring 34. The lever 33 carries a flap 35, that may be moved between the two nozzles 36 a pipe 38 to. the conduit 39, communicating with a receptacle containing com ressed air, (not 'ShOWll,) and by means of t 1e ipes 40 and 41to the cylinders 42 and 43. These aircylinders 42 and 43 have a common pistonrod 44,,h'aving a ring 45 to strike against a pawl 46,- attached to the plug ofthe stop-cock 47, arranged in the com ressed-air conduit 39, that leads to the cy inder by means of which the types are moved. When being upper shoulder of arranged o of the con' uit that connects the canal 4 with the air-cylinder 5. By a connecting-rod 52 the piston-rod 51 of the cylinder 48 is coupled to the shaft 53. A forked lever 54 is keyed to the shaft 53 and notches the slide 55 of the hammer 57, which will cause the types 56 to be struck against the paper.

At the same time the rod 24 will strike against the lever 31 and will .much as the type-wheel continues its rotation the rod 22 of the wor'mwheel 21 will move the lever 33, Fig. 6, until its fla -valve 35 strikes against the nozzle 37. bus a and with it the type-Wheel is stop ed.
