3 Claims.

The present invention is directed to improvements in machinesv which indicate data by means of code perforations in cards and tags, and particularly to mechanism for simultaneously perfo- 5 rating differing codes in a plurality of cards, and for pn'nting the interpretation of each code on the card which has 'been perforated according to that code, and, therefore, constitutes a continuation in part of the copending applical tion of Louis FNWoodruiT and William W. Lasker for Improvements in punching machines,` led October 22, 1931, Serial No. 570,346.

The machine, of which the present invention' is. an improvement, is disclosed in patents to 15 Powers 1,086,397, dated February 10, 1914 and 1,242,721, dated October 9, 1917. These machines provide manually settable means which set punches' to perforate in a record c ard the data 'thatha's been set up on the keyboard. Machines of this character have been in general use for a number of years. 1

The present invention contemplates the combination with the above indicated old mechanism of novel improvements; -whereby a plurality of 25' cards may be perforated. Oney of these cards l will be called the` record card, the other the merchandise. tag. -The record card is of a pattern such as is, used in the Powers tabulating machine, l and the -system of perforations to be used is the code system usually used with such cards. The l merchandise .tag is a card of much smaller dimensions than the record card and uses a perforation code such as that of Woodruff or "Siemens- Halske. The drawings which form a partno this rated according to the Powers 45 column code and the merchandise tag perforated according to the Woodruff code. The above recited perforation codes are typical and the machine is in no way 40 restricted to the use of only these codes.

rlhe accounting system in which these cards would be found useful contemplates that thesocalled record cards might be used for tabulating inventory reports, while'the perforated por- 45 tion of the fmerchandise tag might be used for -tabulating sales information. Reference to the be printed on 'eachj The present invention inf 55 volves means for punching the record cards, and

specification` illustrate the record card perfo- (Cl. lOl-19) merchandise tags-simultaneously, and for printing on each the interpretation of the perforations therein.

One object of the present invention is to improve record card perforating machines to perforate a plurality of cards simultaneously.

Another object is to improve record card perforating machines by the provision of mechanism therein which will print on the card the interpretation of the subject matter indicated by thel0 perforations.

' Another object of this invention is to improve record card perforating machines to perforate a plurality of cards according to differing codes.

Another object is to provide means which operateautomatically to render the machine inactive as need may require.

Another object is to provide means which operate to prevent the machine from being rendered active when conditions indicate that it should remain inactive.

The present invention involves a novel combination of mechanism whereby data cards of differing sizes will be perforated in different codes in accordance with an index set up on a manually operable keyboard.

Other objects and structural details o the invention will be apparent from the following description when read in connection with the ac, companying drawings in which: '30

General description The machine maybe considered as being di- .vided into three sections, which for convenience! which may be present.

The general showing of the card perforating portion of the machine bears a marked similarity -to the machines disclosed in the above cited patents. A Y l a The base (Fig.'1) A suitable base 30, comprising f our legs 3| and a bed 'plate 32, is provided. This frame work supportsl a prime mover 33, which isusually an electric motor.

The intermediate sectilr. (Figs. 1, 2, aind 12/ y A suitable frame work for the intermediate control of operati@ (Eiger, 3,151, 5, and s) Mechanism is provided for starting and forv stopping the machine. 'Ihis mechanism may be' divided into two classes, that for starting the prime mover, and that for clutching the mechanism whenever the machine is `to perforate a card and a tag.

The mechanism for starting the prime mover 5 33 consists of any well known type of snap switch 45. When this switch is set tothe on position, power is supplied to the prime mover 33 and causes it to operate. An alternative means for operating the mechanism of the machine is 10 provided in the hand-wheel 46 .(Fig. 2) and toothed clutch .41. When the clutch 41 is placed in mesh, the shaft 50 is rotated by turning the hand wheel 46. l y

Means are pnovided for manually rendering the machine active by clutching the shaft 50 whenever cards are to be perforated. The mechanism of these means are shown in Figs. i, 3, and 4, an'd consist of a starting button 5|, rod 52, spring 53, arm 54, latch 55, shoulder 56, pawl 60, 20 hook-shaped lever 6|, arm 62, shaft 63, clutch engaging -spring 64, clutch 65 (Fig. 3), ear 63, square pin 10, disengaging lug 1|, and guide 12. The operation of this mechanism is as follows: Downward pressure upon the clutch control but- 25 ton 5| causes the rod 52 to rock the arm 54 clockwise about its pivot and against the tension ofits spring 53. The arm 54 is connected to the rearward arm of the latch 55 by a springpressed pawl 60. The pawl has a shoulder-3o which, when the mechanism is inactive, standsv over the ear 63 on the latch 55. 'Ihe rocking of arm 54, therefore, causes the latch 55 to rock releasing the shoulder 56 on -arm 62. Hence, the shaft 63 .is released, allowing clutch engaging' spring 64 to force the clutch 65 into engagement. The pawl 60 has a square pin 10 which overlies the upwardly extending finger 13 of the hook shaped lever 6| when the mechanism is inactive. The lever 6| is connected to the arm 62v by a pin 14. A spring 15-between the hook-shaped lever 6| and the arm 62 tends to raise the lever`6| against the disengaging lug 1|. The downward motion ofthe rod 52 causes/the arm 54 to rock clockwise about its pivot point and in so doing causes the Square pin l0 to press downwardly upon finger 13 and thus disengage the lever 6| Means are provided for automatically rendering the machine inactive andare shown in Figs. 3, 4, and 5. In order that the mechanism may be in correct position for each succeeding operation it is necessary that unclutching occurs only when the mechanism is in the position corresponding to the end of a card cycle. This is known as full cycle stop". The mechanism of these means consists of cam |06, follower roller |01, bell crank |08, lug 1|, hook-shaped lever 6|, latch 55, shoulder 56, arm 62 and shaft 63. The operation of this mechanism isas follows: 00 The cam |06 has a long dwell and an almost instantaneous advance and return. The shaft- |35, turning in a clockwise direction under the influence of the main shaft 50, causes the bell crank |08 to rock about its fulcrum. The rocking of the bell crank |08 forces the lug 1| which is at the upper end of .said bell crank, against the hook on lever 6|. The motion thus transmitted to he lever 6i is applied to the arm 62 and rotates he said arm and the shaft 63.

7p. to disengage thev clutch 65, thus stopping the machine. The latch 55, under the influence of spring 53, drops over the shoulder 56 and holds the mechanism unclutched. Mechanism is provided for preventing the actu. 15.

6), spring 82, shaft 83, arm 84, link 85,- rocker 86, shaft 81, latch 88, automatic release key 90, pin 9|, spring 92,'arm 93, spring 930, shaft 94, arm 95, link 96, bell crank 98 and pin 99.

The operation of this mechanism is as follows: When the record card magazine 80 is empty, the

' arm 8| permits the spring 82 to rock the shaft 83 ler;

and arm 84, and pull theA link-85, thereby rocking the lever 86, the shaft in a clockwise direction. Clockwisel rocking of the latch 88 permits the key 90, which carries a vpin 9|, to rise under the action'of "its spring 92. The pinv 9| is engaged by the fork of the upper end of the bell crank 98. Hence, the rising pin 9| causes the bell crank 98 to rock in a counterclockwise direction. The pin 99 is thus forced rearwardly and moves the pawl 60 out` of its normal position. Depression of the rod 52 will now be ineffective as regard the latch and lever 6I. (See Figs. 3 and 4) The rearward motion of the pawl removes the square pin 10 from its position above the finger 13. Hence, it is impossible to unlatch the hook 6| from the disengaging lug 1| and starting of the machine is prevented, even though the key 5| is depressed.

lMechanism, (Fig. 6), consisting of arm 93, spring 930, shaft 94, arm `95, link 96 and spring 91 is provided for preventing the actuation of clutch when the merchandise tag magazine |00 is empty. The operation of this mechanism is as follows: When the tag magazine |00 is empty arm 93 rises under the action of spring 938 and rocks shaft 94 and arm 95 counterclockwise. This rocking pulls link 96 rearwardly and vrocks lever 86, shaft 81 and latch 88 clockwise,

releasing automatic release key 90, and rendering rod 52 ineffectiveVas was described above.

Repeat key (Figs. 3, 4, and 5) groups, which are: that which controls the clutch mechanism and that which controls the setting of the perforating andv printing mechanism. The first of these two groups will be considered at this point, while the second group will be described hereinafter. The mechanism for. the repeat" control of unclutching is shown in Figs. 3, 4,

and 5, and consists of repeat lever H0, detent- |H, detent spring H2, link H3, leverl H4, U- shaped lever H5, pins H6 and H1 thereon, pin H8 and spring H9. The operation of the repeat mechanism is as follows: The repeat lever H0 is moved rearwardly and held by the detent IH under the action of lspring H2. The link H3 is carried at the lower "end of the repeat .lever H0 .by a pin and slot connection. The link ||3 carries a pin which engages the'forked upper end of lever H4. Thelever H4 carries a stud which serves as an anchor for one end of the spring H9. One arm of the U-shaped lever ||5 carries a stud H8, which serves as anchor for the other end of spring' H9. The lever H4 is provided with a lug at its lower -end whichis normallyV kept in contact with the stud [I8 by the spring H9. The motion of repeat lever H0 pulls link H3 forwardly rocking levers H4 and H5. The tension of spring H9 causes pressure to be applied to the rearward end of Vhook-shaped lever 6|, forcing it downwardly and out of the path of dis- 81 and the latch 8B engaging lug 1|. Hence, the full cycle stop cam comes exhausted during repeat operations. The

mechanism of these means is shown in Figs. 3, 4,'andl5, and consists of hook I2| on theautomatic release` key 90, U-shaped lever H5, pins H6 and H1 thereon, and spring H9. The operation of this mechanism is as follows :-When the stopping mechanism, associated with an empty magazine, is. actuated, automatic release key 90 rises causing hook |2| to lift pin H6, lever H5, and pin |-1 -against the action of spring I9. The lifting of .pian-H1 permits the hook 6| to again `engage the disehgaging lug 1|, and upon the completion of the cycle, cam |06 rocks bell crank |08 clockwise, thereby pulling lever 6| rearwardly and rocking arm 62 clockwise-into position to be latched by member 55, The machine is thus brought to a full cycle stop. f

Drive mechanism (Figs, 8, 9, and 10) i trolling the various functions of the record card Y end of the machine. In addition, the worm |3| drives the two worm wheels |32 and shafts |33 which are associated with that element in the card transporting mechanism frequently called skid rolls. l

The rearward frame 4| contains mechanism comprising worms |36 and |31, worm Wheels |38 and |39, and shaft |40 all of which areassociated with the functions of the mechanism of the merchandise tag end of the machine. Since the tags are to travel in a direct opposite to that of the cards the worm and wheel mechanism is of necessity, left-hand. The members 42 provide space for the starting switch and the clutch con- Vtrol mechanism and journal for the transverse shafts of the card transporting and clutch actuating mechanism.

Card handiing mechanism (Figs. 4, 9, and 11) Means ae provided for storing, selecting, 'transporting and receiving cards which are to pass through the record card perforato'r. The` device for storing the cards consists of a rectangular frame 8,0, which rest upon brackets 44 (Fig. 1) which are mountedf'oi' frames 4| and 42 respectively.

The mechanism of the' selecting means lis |50, follower I5|, arm |52, spring |520, link |53, arm |54, shaft |55, arm |56, link |51l and picker |58. The operation of the selecting mechanism is as follows: Shaft |35 rotating under the inshown in Figs. 4, 9, and l1, and consists of cam fluence of the shaft 50 carries with it cam |50 which acts upon follower |5| mounted on arm h|52, and through said arm oscillates arm |52 counter-clockwise about its pivot.' This motion pushes link |53 forwardly and causes arm |52, shaft |53'and arm |54 -to be oscillated against the action of spring |520. Oscillation of arm |54 moves picker block |58 laterally through the medium of link |55. I'he combined, action of cam |50 and spring |52 acting through the above described mechanism, imparts a. reciprocatory motion to picker block |58, thereby selecting the card adjacentthereto, and feeding it toward the pair of rolls |60 and |6| which are --turning with the shafts |33 under the influence of drive shaft 50. To prevent all but one card from being drawn out of the magazine, a throat knife |59 is provided at the rear of each storage 'magazine.

Card transporting mechanism (Figs. 8, 9, and 11) Means are provided for transporting the se lected card into the chamber of the perforating mechanism and thence to the card printing mechanism and card receiver. The mechanism of this means is shown in-Fig's. 8, 9, and 1l androtate in a counter-clockwise direction. Suitable tension is placed between ithe rolls and when the card is received from the picker block |56 it is moved rearwardly into the punching chamber.

' Upon the completion of the punching operation.

interpreted code.

the rolls |62, |63, and '|64 under the influence offthe shaft 50, cause the card to move onwardly in the direction of the ,printing mechanism where itisagain stopped to receive the imprint of the 'Ihe rolls |65 and. |66 also under control of the shaft 50 will cause the card ,tn again move onwardly when released by theA print chamber card stop. It will then pass into the receiving magazine. Card stopping mechanism (Figs. 4, 5, 9, and 11 Means are provided for stopping the card in the punching chamber, and also'over the printing platen. Themechanism for this purpose is shown in Figs. 4, 5, 9, and 11 and consists of cam |68, arm |69, follower roller |10, rocker lever |1|, shaft |12, card stops |13 and |14, and spring |15.

This -mechanism operates in the following manner: The cam |68, turning with the shaft |35 under the 'influence of the drive shaft 50 actuates the followerlroller |69 land arm |10 oscillating the rocker |1| about the shaft |12 and reciprocating the card stop |13 and |14. As the follower roller passes from the high dwell to the Alow dwell of the cam |68, under the action of a spring |15, the card stop |13 will be withdrawn -from the path of thecard and thev card stop |14 `will be raised into said path. It is seen that the. mechanism so operates as to permit thefeeding of a card during a stage of the operation of printing on the preceding card and that each card is released from the printing chamber be- .fore the succeeding card reaches the perforator card stop.

Pcrfomtinc mechanism (Figs. 9 and 11) Means areprovided for'perforating the record cards. The mechanism of these means is shown in Figs. 9 and 11 and consists of box cams |50,

'followers |80, punch frame |8|, punch frame guide plates |85 and stripper plates |86. Shaft |35, turningl under the influence -ofthe drive shaft 50, turns the pair of boxcams |50. Fol.- lower rollers |80, engaging the cam groove, move punch frame |82 witha reciprocatory vmotion along the punch frame guides |82 and raise the 5 punch plate |83 upwardly against the4 punches |84. Means which will be described hereinafter set the appropriatel punches.

Tag handling mechanism (Figs. '2, 9, 1o, and' 11) lo Mechanism, identical to that for ,handnng record cards except for minor structural changes, is

provided for the handling of the merchandise ciplevof all the above listed elements is identical'25" to that of the record card selecting mechanism. The tag. transporting mechanism is of the same general character as that for record card transl porting, and consists of rollers 206, 208, 209 and 2|| mounted on a set of shafts 2|3 driven by.30 worm wheels |38, rollers 201, 2|0, and 2|2, and.V an auxiliary picker mechanism.' This auxiliary mechanism consists of cam 2|6, follower roller.

' 2|1, arm 2| 8, shaft 220, spring 2|9, arm 22|, a

-r-sha-pcd member 2`22, hooks 223, rouers zia-'ami35 guides 2'2-5. 'I'he operation of the auxiliary mechanism is as follows: Cam 2| 6, mounted on shaft |40, turns under control of main drive shaft 50. Follower roller 2|1, acted upon by cam 2| 6, actuates arm 2|8 against the action of spring 2|9, 4 0 thereby oscillating shaft 220.. Oscillation of shaft 220 will cause arm 22|, through the medium of member 222, to reciprocate hooks 223 in guides 225. The depressed ends of guides 225 permits rollers 224 to carry hooks 223 to a position be. 4 5 low the path ofthe advancing tag. Hence, when,V the hooks 223 move forwardly they will engage the tail edge of a card and position it against card stop 231 where it remains during the printing operation. The gradual rise of follower 2| 1 to4 50.

point |2|6 on cam A2|6 .thus causes acessation of motion of hook 223 and the intervening mechanism. When printing is complete Vand card stop 231 withdrawn, follower 2|1 rides down the sharp' descent on cam 2|6 causing the intervening. 5,5 mechanism to urge hook 223 forward and thereby transport the card toward the rollers 2|| and 2|2 and thence, into the tag receiving magazine.

Tag stop Fig's. 9, 10, and 11) tag in the punch chamber is as follows: 'I'he cam" 230 turning with the shaft. |40 actuates follower 23| to elevate arm 232 against the action of 70 spring 233 and to oscillate shaft 234, to which arm 232 is fixed. Elevation `of, arm 232 will therefore" cause oscillation of levers 235, the elevation of tag stop 236 and the retraction of tag stop 231. The
