In 518 fioiiowlng flescriptioo and in the ciainis the various and details of the invention wiil be identified by specific names for conrenici'ice, but they are intended to be generic in their applicahion as the art wiii permit.

Referring to the drawings more the printing mechanism may comprise 9, r0- tatubie cylinder 10 carrying ziplurzili't-ylof peripiicrziiiy space-Iii i'ypc characters such as for exampie as the digits 0 to i) or (3 to 12 and mounted. for rotation on rod 11. Said in detail,

resgtvcctiveiy. Sapporo; and

il'y-n'iounied in standards 16 and psrrrs of apparatus.

cured thereto and adapted to mesh with gear wheels 21 and 22 carried on rod 11. The number of teeth on wheels 21 and 2:5 should correspond with the number of peripherally spaced type characters on cylinder 10. Shaft 18 may be driven from a source of power (not shown) and caused to impart.

keys 26. \Vhen a key 26 has been depressed the corresponding interposer bar 5 is forced into engagement with stop 2+1 and interrupts the rotation of shaft 11 together with cylinder 10 attached thereto.

Gear teeth on wheels 19, 20, 21 and are constructed with contacting surfaces sufficiently flattened to allow the teeth of one of said wheels to exert a cam action on the teeth of a eo-operating wheel and to force said wheels apart wheneverrelative peripheral movement takes place. One. wheel may therefore be locked against rotation and the continued rotation of the other wheel will cause the teeth to ride upon the teeth of the other and exert a cam action thereon for separating the wheels and the correspond ing shafts as shown in Fig. 3. Cylinder 10 attached to shaft 11 then in depressed or printing-position.

The shafts remain separated until the teeth have slipped past or disengaged when the.

gear wheels may again mesh. '.l.liey will then be displaced by one. tooth from their original meshing position and will so remain provided both wheels are again allowed to rotate.

When shaft ll is Forced into printing" position as aforesaid, interposei- 25 is rotated tion when said hey is re] about its pivot 30 to its original position and is engaged by cam ill and retained in that position. Consctpicutly when shaft 11 is displaced by springs 23 and brought into operating position with respect to the power shaft, stop 2-l discngzagcs 'l'roin intcrposer 125 and said shaft 1]. may again rotate.

Cam 31 is held by spriup $52 in engagement with a double wedge surface on interposcr 25 and serves to maintain said ii' terposcr in either raised or lowered position. Should a. key 26 be depressed, however, when interposer 25 opposite av stop member 2% and is prevented thereby from moving into eugaging position, cam 31 will prevent the inter-poser from returning to normal posisod and will force said interposer into engaging position as soon as stop 2% has passed the end thereof.

The interposer will then co-operate with stop 24 when said stop is again brought into operative position and lock shatt 11 to initiate another printing operation.

Should key 26 be depressed and'innnediately released, cam 31 will co-operate with interposer 25 and hold the same in engaging position until positively released by a printin; operation as above mentioned.

The type cylinder may be provided with a double set ot. characters, each occupying half of the periphery and two stops spaced by 180 degrees may be employed tor co-opcrating with each inter-poser. The shaftwould then be stopped for printing within a halt revolution after any key is depressed and the speed. of operation correspondingly increased. Obviously any other desired number of sets of .-haracters could be employed and the number of: stop members and the. number of teeth on the' gear wheels similarly increased.

The above mentioned apparatus may be operated by a suitable timed impulse such as that produced by a card having index point perforations. .ln the modification shown in Fig. a plurality of stops 34 are shown peripherally spaced to correspond with the various peripheral type elements. ()ne blank is therefore used for the entire set of stops and the number of parts correspondingly reduced. lhe'printingoperation is controlled by depressing interposer 35 in suitable. time relationship to the rotationof shaft 11 for co-operatiug with the desired stop member 34. Continuous rotation of the power shaft will. then depress the type wheel, print the corresponding characters and restore inter-poser to its original position as desired above.

. lntcrposcr may be operated by a solenoid 3b in response to timed electric current or may be operated by other well known means of remote control. ( ircar wheels 21 and 22 should be so arranged that a tooth is in the uppermost position when thewheel is in any stop position in order to obtain the fullest cil'cct of the cam action of the cooperating: teeth.

in accordance with the present invention,

a rotary typo cylinder may be a. constantly revolving power utilized h pnly avoids interruption of the power shaft but utilizes the power derived therefrom for bringing the cylinder into printing position. Since ii ment of the two actuated by shaft, and

gear wheels is 'utilized 'for effecting a printingoperation, the interrup of the type wheel in automaticallycauses tion of the movement any desired position the cylinder to print and release. The apparatus is.simple in construction andre a printing operation which not the relative peripheral move-- tions and changes in the type wheel forced rotary type quires hut relatively few parts. it may he operated in eonjunetion with a card punch or may he applied to any of the well known eonunereial a ounting machines sue-h as for example, an adding marl-tine, cash register, typewriter or stoek ticker. it the arrangts ment, is operated hy remote eontroh as hy means of syneh'ronous ele trie impulses, it may he applied to a tahnlating mat-lune and op rated in tttjt'tut'tltttttjti with eards haying index point perl'oratirms.
