(See complete set of lower case alphabetic characters. Fig. 9.) It is understood that as is usual in tabu At this time there will now be explained the man lating machines the card feed clutch is so de ner in which numeral printing is effected under signed and the gears are so proportioned that 45 control of the card perforations 0 to 9, inclusive. _ shaft 3l will be given a complete revolution in the In Fig. 3 it will be observed that for the selection arrow direction shown in Fig. 2. of the numeral printing characters 1 to 9 a vari It is customary in the type of machine described able rotation of the printing wheel 40 in a coun to cause printing from numeral type of a printing terclockwise direction is necessary, it being ob mechanism which are presented to a, printing line 50 served that to select the numeral type "1” the and which are selected in accordance with the least counterclockwise rotation of the printing analyzing of the perforations of the card, and to wheel 40 is necessary whereas for selection oi' the carry out the numeral printing function in a novel numeral type 9 a greater extent of rotation of manner the improved construction will now be the printing wheel 4|) in the same direction is described. 55 necessary. A clutch controlled type selecting mechanism is provided for eiïecting this variable rotation under control of the 1-9 card perfora tions. The printing mechanism constructed as shown F‘rom Fig. 3 it will be observed that the numeral herein may consist of a plurality of orders, the 60 printing characters |-9 are provided on alternate number being dependent upon the number of Digit or numeral printing mechanism gear teeth of the printing wheel 40 and said gear numerical or alphabetical characters which are teeth mesh with the teeth of a clutch gear 53, to be printed. Fig. 3 shows a plurality of control magnets for four orders but the type selecting there being, of course, one clutch gear for each mechanism for one order and it is to be under 65 printing wheel 4I. The main drive shaft 3l drives through an intermeshing gear 5B (Fig. 9), stood that the type selecting mechanism is du~ plicated for as many orders as is required. a shaft carrying tube il and which tube is pro vided on its periphery with ratchet shaped clutch The printing elements preferably consist of one teeth il. these teeth being coextensive with the or more printing wheels 4|l, each of which is cen trally apertured so as to overlie a ñange or hub 70 length of the tube 51. The clutch teeth Il are arranged in three groups of eighteen each and 4|. The hub 4| is integral with an arm 42 pivoted through the intermediate gear driving connection upon a rod 43 and the rocking of such arm will 5I with shaft 31 the tube l1 is given one and one carry the selected printing type of the printing third revolutions for each cycle of operation of wheel 40 against a conventional platen 44, it be ing understood that interposed between the print 75 the machine. The clutch gears I3 are mounted 8,386,422 upon the tube I1 and are suitably spaced the same width as'the printing wheels Il so that each clutch gear I3 will mesh with the related printing wheel ll that it drives. Each clutch gear Il has pivotally mounted thereon a clutch pawi I! provided with a clutch tooth il. A spring Il secured to the clutch pawl Il normally urges the clutch pawi Il so that the clutch tooth Il will engage one of the ratchet teeth I’ but such action is normally restrained by a clutch release arm Il. the arm having a projection ll which normally engages an exten sion ll of the clutch pawl Il. As is weil known in the operation of the clutch mechanism now being described, at the moment the clutch release arm 02 is rocked the clutch pawl 6| will be free to engage one of the clutch notches 5l and since the tube 51 is driven in a clockwise direction the clutch gear 53 will be driven in the same direction so as to rotate the printing wheel 40 eountercloclrwise. The clutch engagement of the clutch pawl 59 and the engaged notch Il is maintained until the extension 84 of the clutch pawl 59 again strikes the extension 83 of clutch release arm 82 which, in the meantime, has returned to the normal position shown in Fig, 3. This will disengage the clutch pawl 59 from the clutch tooth 5B it engaged. It will be observed that in the normal position of the clutch pawl U9, this position is also maintained by a detent block 66 which is integral with the clutch gear I3. The clutch teeth BI are arranged in three sim ilar groups and one of the teeth designated l, 2, 3 ...9 of the group which is effective is en gaged by the clutch pawl 59 to effect the desired extent of rotation of the printing wheel to select the printing characters 1 to 9, dependent upon which tooth is engaged. The manner in which 3 rotation of the shaft 1l the operating disk l! will be given an extent of movement which is depend ent upon the perforation analyzed, the disk being given greatest extent of movement when the I perforation is in the column and the least extent of movement when the i perforation is analysed, as is evident in Fig. 3. The means ior rocking the shaft 1l is best shown in Fig. 6, wherein it will be noted that se cured to the main drive shaft 31 is an eccentric cam II and cooperating with the cam 83 is a fol lower arm Il which is an integral part of a seg ment l5 meshing with a gear Il secured to the rock shaft 1l. ’I'he formation of the cam ll is such that as the card pertoratlons pass the analyzing brush Il the segment Il will rock shaft 10 to cause the correspondingly designated ratchet teeth 1I to pass by the clutch pawl 1l, as is evident from the timing diagram of Fig. 4. The clutch disk 1| is therefore, rotated at a con stant speed from the beginning of a machine cycle to 184°, then accelerates in speed. and thereafter ` to a constant speed to 269°. (See Fig. 4.) After 269° shaft 10 and clutch disk 1| are rotated in a reverse or clockwise direction. In so doing a pro jecting cam portion l1 of the clutch disk 1I bear ing against the extension 1l of the clutch pawl 1I causes operating disk 02 to be restored clock wise. The cam U3 (Fig. 6) is provided with a cam surface which will cause the clutch disk 1I to be rocked counterclockwise slightly beyond the posi tion shown in Fig. 3 in order that the clutch pawl 14 is relatched by the clutch release arm 19. After such relatching clutch disk 1| cornes back to the normal position shown in Fig. 3. The variable extent cf counterclockwise rota tion of the operating disk 82 is provided to deter mine the time of engagement oi the clutch pawl 59 with the clutch tube 51 in the following man ner: The operating disk 82 carries guide pins 8B the desired clutch engagement with the required receiving guide slots 89 of an arcuate plate Sii. clutch tooth 53 is effected under control of the A latch pawl 9i latches the plate Sil in the posi card perforations will now be described with par tion shown in Fig. 3 against the action of a spring ticular reference to Fig. 3. 92 connected to the plate Sil and which spring is Reference numeral 10 designates a reciprocat ing shaft which is rotated counterclockwise 180° 45 also the operating spring for the clutch pawl 14.

The operation of the machine as far as the It will be observed that as far as the perform control by the 0 perforation is concerned is pre ance of the machine for printing capital letters is concerned the different groups are selected by 65 cisely the same but it will be observed that in the case now under consideration instead of the presence of the R, X, and 0 periorations and the character W being selected for printing the that printing occurs at three different points in gear 53 will not be rotated to as great an ex the machine cycle and when printing oi' nu tent, this diilerence being equivalent to the space merals is considered, printing can be eifected at four diiïerent times during the machine cycle. 70 between successive type of the printing wheel IB, enabling the character "w" to be selected for This is of particular advantage because of the printing. This is readily evident because in the reduction of load in the operating parts of the previous example the gear 53 is rotated an extent machine permissible over constructions where of eleven teeth under control of the 6 perfora printing is eiiected from all the printing wheels at a single point in the machine cycle. 75 tion line whereas the supplementary perforation 8 9,388,423 5 changes the control so that the gear 53 is ro tated only ten teeth and this rotation will cause the selection oi' the character "w". The other characters in lower case are selected in sub stantially the same manner, it being observed that for the selection of the type j, k, l-r the X perforation is utilized, whereas for the selection of the remaining type o! the alphabet, namely s, t, u to z the 0 perforation is utilized in combina tion with successive perforatlons at the numeral index point positions. It should also be observed that due to the inability of the machine to utilize the zero perforation as a pilot hole and also as one of the numeral index holes in the tion, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its oper ation may be made by those skilled in the art without departing from the spirit of the inven tion.
