(ci 164-115) w andthe 'associated manually operateakeybmd 'I'his invention relates to improvements' in record perforating systems and more particularly where the data representations are made in one code on a tape under control of a record perfo-Y rated in a different code.

More specifically the invention .resides inthe Yimprovements in an appmatus .whereby information recorded on a statistical or tabulating card may be perforated on a tape suitable for controlling the operation of a tape controlled printing machine or transmitter.

Machines of this character have been devised as exemplified in the patent to c. R. Doty', No. 2,340,800, granted February 1, 1944, and the presentinvention is directed toimprovements whereby provision may be made for supplementally per. forating the tape with variable information at predetermined sections thereof under control of a manually operated keyboard. Hence, each perforated section of the tape corresponding to the. data derived under control of a tabulating or stacircuits.

tistical card may be perforated to receive variable infomation by the operation of a manually Voperated keyboard.

Another object of Ithe invention isfto eect the., suppression of the automatic tape perforating operations when predetermined positions of the record cards are reached and lto enable the posifor manuallycontrolling supplemental tape pertorating operationa- Fig. 2 represents a fragmentary portion oi a statistical card shown perforated-to represent` the statistical code for letters and digits.

tions of the record cards where such suppression effected to be varied at will.` v

Another object of the, invention is to enable the restarting of the automatic card sensing and tape punching operations by an additional inanual operation -wh'en the manually controlled punching is completed.

Another feature of the invention is to devise electrical circuits whereby key operations initiate the cyclic operation of the tape perforator and select the tape punching control magnets according to the vtelegraphic code. There is also included as a feature of the-invention an electrical arrangement whereby repeat tape punching op- -erations cannot be inadvertently eiected whenever a key is held depressed beyond the normal .period within which it should be released.

other objects of the invention will be pointed out in the following description and claims and A illustrated ni the accompanying drawings, which.' Y disclose, by way o! example, the principle of the Y invention and the best mode, which has been' contemplate@ `of applying that principle.'

Fig. 8 is a diagram of circuit connections of the electrical parts of the apparatus comprising the present improvement. f

Before describing in detail the construction and operation of the present improvements, it should s be observed that, for the purpose of illustration. the present improvement is shown I'in connection Awith the form of record controlled tape perforating apparatus shown and described in full 'detail in the patent to C. R. Doty, No. 2,340,000, granted the reciprocable card carriage comprising the pusher I3 and guide kIl engages th card 'and advarices it column by column under' control oi the escapement vmechanism to be described latex-i'J The sensing station includes a group of 'indie details of the sensing unit are disclosed in the patent to Doty, No. 2,340,800 as well as the function thereof which, in general, is to set up control relays and translating relays and the latter are selectively energized in accordance with the sensed data designations on the record card.

The aforementioned Doty patent discloses in complete detail the translating mechanism controlled by the translating relays which, through their associated contacts, are effective to translate designations sensed in the statistical code to the 5-unit telegraphic or Baudot code and accordingly control selectively the energization of the tape punch control magnets!" (Fig. 7) -in .different code combinations, thereby causingr the code designation perforations representing the 'data sensed on the'record cards to be punched in the tape 200.

Incidental operations, namely, card feeding and card ejecting operations of the record sensing unit, are substantially the same as that embodied in the machine well known as the International duplicating key punch" and Alphabetical verifier," such as is shown, for example, in Patent No. 1,772,186 t0 F. L.` Lee et al., U. S. Patent N0. 1,914,263, dated AJune 13, 1933, and U. S. Patent A No. 2,107,161, dated February 1, 1938'.

Associated with the escapement mechanism are the well known floating cam contacts |49 (Fig. 8). Such contacts are open during the escapement of the card carriage from one column to the next and when the card carriage' comes t0 restafter having escaped through the distance of a card column, contacts |49 will come to normal positionin which theyare closed.

Also included in the punching machine are the well known latch contacts 35,V 36, shown in Figs. Gland 8. The purpose of such contacts and the manner in which they are 'transferred is fully explained in the Doty patent, No. 2,340,800 and for an understanding of the present invention it is only necessary to recognize that normally the contacts are closed.

The' tape perforating unit related latch arm 222 is rocked in a clockwise direction so that its latch fingers 224 engage and latch the free end of the related interposer 2I'I. Thus, upon latching of an interposer 2|1 and rotation of the eccentric. 2|! the said interposer is positioned by the eccentric about the pivotal connection formed by the latch arm and the latched end of the interposer to force the related punch plunger 2|0 downwardly, thereby causing the tape interposed between the lower ends of the punch plunger and the die block 2| to be perforated.

The control means for selectively positioning vthe latch arms 222 and thereby select the punch inthe punching operation but they are not described herein since full details of their construction and operation may be had by reference to' the aforementioned4 patent to Doty, No.

By means more fully described in 'the aforementioned patent, centrally located feed perforations 202 (Figs. 3 and 4) are formed as the tape is perforated. The paper tape is drawn from a supply roll (not shown) to the punching station by a feed roller 240 secured to a drive shaft 24|. Said feed roller` 240 is formed at its periphery with teeth 243 which' cooperate with the centrally located feed perforations of thetape 2li. The step-by-step rotation ofthe feed roller 24| feeds the tape 200 so as to present successive coiumns of the blank portions of the unperfora tape 240 to the punch plungers 2 0.

The operation of the punching mechanism of the tape perforating unit, as well as the operation of the tape feeding mechanism performed in the necessary sequence are initiated by the energization of the clutch control magnet 280, shown only in the wiring diagram of Fig. 8. In the Doty et al. patent complete details are shown of the manner in which such clutch control magnet effects the operatibn of the tap perfor-ating unit. For understanding the present improvement it is `sufiicient to know that this initiates the operation of the punch drive shaft 22|, the shaft 24| for lfeeding the tape and other operating elements of the punching machine to eilect the punching and tape feeding operations.

perfor-ating portion of the apparatus includes individual punch plungers 2li), one -ior each imit- 7 220 of the tape perforating unit. Normally, during the rotation of the eccentric, each interposerJ is moved downwardly and upwardly by the sup-` porting eccentric about the pivotal connection formed by the endaof the interposers engaging `the recess 2|6v of the related punch plunger.

For each interposer 2|1 there is'provided an yindividual laten arm zzz. whenever it is desired to select a punch plunger 2|! for operation, the

Operation The general loperation of the machine will given in connection with the circuit diagram `and a more detailed descriptionv will be lgiven of the present improvements when that point of the specification is reached; It will be assumed for the purposes of illustrating the utilization of the present improvement that one of the record cards is perforated to control the punching of a section of the tape as indicated by the message 123 JOHN JONES 567 on the' tape 2li shown in Fig. 4. The .manner in which the apparatus effects such tape punching under control of the record card for the particular message .shown in Fig. -4 is described in complete detail in the aforementioned patent t0 Doty, No. 2,340,800, and ibWill be assumed that priorita punching the complete m sageonlfig.4theapparatuscornestoaatoptol enable interpolation `of manual punching on a section of the tape, under control of the manual keyboard K to represent some variable data not designated on the record card C. It will also be understood that for each sensing operation of the record sensing unit, an impulse is directed to the tape clutch magnet 28|- to bring about the cyclic operation of the tapeiperforating mechanism. With the present improvements coordinated with the apparatus shown in the Doty patent, the circuit for etecting the cyclic operor one of the functional keys lI-IB.

ation of the tape punch is from the lineA 30|,

through relay contacts X2 now closed. through the latch contacts 35 now closed, thence through the .floating cam contactsV |49, the tape clutch magnet 280, through cam contacts CI to line 35|. With the exception of the provision of the normally closed X2 contacts, the circuit is the same as in the Doty patent and impulses will be directed by this circuit to the tape clutch magnet 280 as long as the X2 contacts remain closed.

Manual punching operations are eiected by the keys of any suitable keyboard K shown diagrammatically in Fig. l which may consist of the form of keyboard shown in Figs. 1 and 8 of the patent to O. B. Shafer, No. 2,315,741, granted April 6, 1943. Details of construction of this keyboard are not given herein since they may consist of the 'detailed arrangement in the patent..

Operable exteriorly of the keyboard K by the operator are digit keys 40, depressible to control punching operations to represent the digits 1-9 and on the tape 200. Additional keys are mounted on the keyboard to eil'ect supplementary punchings which are required in a control tape for proper interpretation by the tape controlled printing machine. Such keys are the space key It wmbe observedtnat the 1owest Contact blade of each of the keys. has a wire connection 52 to a conductor 53 so that when the lowest contact of each of the keys is closed a supplementary circuit will be closed through itsV lowermost contacts I8, the wire 52, the conductor I53, through the Y relay to line energizing the latter. The Y relay will close its contactsv YI, closing a circuit from line 300, through WI contacts now closed, Lthe YI relay contacts now closed, through the tape clutch magnet 280, through cam contacts Y CI closed at the rest position of the punch, to the line 30|. The WI contacts are controlled by the slow-to-operate W relay which is timed tc open the 'WI contacts only after,l the impulse is sent to tape clutch magnet 280. By this circuit the 1I, the iigures'shift key 42, the letters shift key 43., and keys 44, 45 and 46 for eecting punching A of certain coded designations on the tape which are utilized in the tape controlled printing machine for eiiecting certain functions therein to provide correct printing of the data. The keyboard also includes a' key' l1 which is manually depressed to resume'automatic record sensing and concurrent tape perforating operations upon completion of manual punching operations for. the desired number of columns of the tape. Each of the aforementioned keys 40 to is adapted4 to close related contacts 48 which are wired to digit wires 49 designated I, 2, 8, 4 and 5 inFig. 8 and which correspond to the number of units of the Baudot code., The wires I9 are connected to respective relays Z which are energized upon the depression of the keys of the keyboard by a circuit which leads from the line "I through relay contacts'XI which are closedrwhen the manual punching operations are to be eiected.

and wire-5l which is electrically connected to theuppermostl blade of the contacts closed by the keys, thence through the contacts 'Il to the digit wires I9 that such closed contacts have wire con- Y nections thereto',A to the corresponding Zrelays, thence through the C1' contacts which-are now closed, through W2 contacts back to line ill.

tape clutch control magnet 280 is ener'gized whenever the keys lli-; of the keyboard are depressed to thereby eie'ct a cyclic operation of the tape punch and cause by the selected tape punch magnets 29B the desired tape perforation.

When the cyclic operation of the tape punch has4 been initiated, cam contacts C2 will close at substantially the .midportion of the cycle and a circuit'will be closed from line 300, through the C2 contacts, which correspond to the same designated contacts in the Doty patent, thence to the particular ZI relay ,contactswhich are closed, through thetape punch magnet 290 in circuit connection with the closed ZI contacts, to linell.

The keyboard is rendered effectivefor tape punching operations only when relay contacts XI are closed, and closing of the latter is effected at predetermined positions of the carriage of the record sensing-unit by the selective arrangement now to be described.

:The circuit forthe X relayr is from the line` 30D through normally closed contacts 54 which, however. are opened by the depression of the v Vboardv eiective for manual punching operations by closure of related xl contacts can be effected From Fig. 5 it win be noted that at the rest position of the tape punching machine, cam contacts -C1 are closed to 'enable the completionvof the de -V scribed circuit. Each of the aforementioned Z relays ls adapted'to close related contacts ZI to thereby select the appropriate tap`e punch selecting magnet 290. Whenever a contact 4 is closed by a key, it will select forenergization, through.V

by anyselective arrangement. For the purpose of illustration, it is preferred to utilize the card carriage control of such contacts by the arrangement fully shown and described in the patent to Ft L. Lee et al., No. 1,772,186. The card carriage of the record Sensing Yunit of the present apparatus has likewise a b ar 51 which is secured tothecardcarriage andhavingat column intcrvals openings 5I into which may be inserted the shank of a set screw 59 threaded in a block adjustable on barf51. The block 6b may be adjusted and fixed on Ythe liarV 51 at any predetermined card column 'posiom For purposes.-

of illustraon, it will be asumed that after the tape has been perforated to designate the` space theV digit wire 49, the particular Z relay that the 15 on the tape 2 after perforating the tape to represent the letter S of the word JONES, the

56 to occur so as to open the X2 contacts be- Y fore the iloating cam contacts |49 come to closed position after spacing the card carriage of the record sensing unit to thereby prevent the norfmal impulse from being transmitted to the tape clutch magnet 280 when cam contacts Cl close. Energization of the latter is thereby eiected only upon each subsequent key depression of the keys "-46 of the keyboard through the energization of the Y relay coil.

The X2 relay contacts in addition to rendering the normal impulse circuit for energizing the tape clutch magnet 280 inoperative also open other circuits incorporated in the electrical wiring of the record sensing unit to render this unit completely inoperative during manually controlled punching operations.

One of such circuits is the energizing circuit for the escape magnet 40 (Fig. 6). This circuit with the exception of the X2 'contacts is the same as in the aforementioned Patent No. 2,340,800 and is from the line 300 through the X2 contacts, latch contacts 35, wire 303, through the Rla and R|a relay contacts, cam contacts C2, escapement magnet 40 to line 30|. Hence, with the prent circuit arrangement, the opening of the X2 relay contacts after the carriage of the record sensing unit has escaped from the last sensed position the impulse circuit for the escape magnet 40 will be ineilective and therefore the carriage of'the record sensing unit will remain at rest position until the completion of manually controlled punching operations.

The opening of the X2 relay contacts also opens the circuit connection which extends from the iioating cam contacts |49 to the contact roll 9| of the record sensing unit. This circuit is not compictely shown herein and reference may be had to the aforementioned patent. The opening of the X2 relay contacts therefore renders the sensing mechanism of the record sensing unit inoperative.

The X2 relay contacts when open, open all of impulse circuits connected to line 302 which circuits are completely shown in the aforementioned patent. The opening of the circuits connected to the line 302 will prevent improper energization of any of the relays to which impulses would be normally transmitted by the wire 302.

summarizing, the X2 contacts when open 'render the operating devices of the record sensing unit completely inoperative and retain it inoperative until tne termination of manually controlled punching operations.

Therefore, it will be observed that the record a supplemental number which is variable but may consist of any other data, depending upon the use to which the present improvement is made. When the apparatus has come to a stop, the operator lin the assumed example depresses the iigure shift key 42, resulting in a cyclic operation of the machine and the perforation of the tape to represent the code designation (see Fig. 4). Thereafter, the digit keys are successively depressed to perforate the tape to represent the digits l, 9, 8, 7, 4, 3, and 2, forming part of the number of the assumed example. When the operator has manually entered the desired digit punching on the tape, the key '41 is depressed tacts now closed to line 30|.

to lopen contacts 54 to deenergize the X relay. The latter now releases XI contacts and they open to disconnect the contacts of the keyboard from the line 300, rendering the keyboard ineffective. As the X2 relay contacts come to closed position an impulse is directed to the tape punch clutch magnet 280 and automatic tape punch operations are resumed thereafter until the complete message has been punched on the tape for the record card sensed. The key 41 is preferably held down during the subsequent tape perorating and record sensing cycle to insure proper operations.

To retain the Z relays energized so that their related Z| contacts are sure to be closed during the time that the C2 cam contact closes the circuit for the selected tape punch magnets, each of the Z relays has a related Z2 holding contact. The stick circuit for each Z relay is from the line 300, through the related Z2 stick contact, the associated Z relay coil,'cam contacts C1, W2 con- This stick circuit retains the relay contact Z| closed so that when C2 cam contacts close the tape punch magnets the slow-to-operate relay W, and cam contacts CB to line 30|.

If the key is retained depressed after cam contacts C1 open and when cam contact C8 closes,

the Y relay coil is held energzed to close the -Y2 contacts and the W relay will be energized as long as the key is held depressed. The W relay is of the slow-to-operate type but shortly after cam contacts C8 close the Wrelay opens the Wl contacts which are in the impulse circuit to the tape clutch magnet 280. If the key is still held depressed at 0, it is clear that the opening of the W2 contacts prevents the selective energization of the Z relays at 0 at which time cam contacts C1 are closed. If the key1 is still held depressed at the end of the cycle and sensing unit` and tape perforating unit operate having been observed by the operator of the key,.

board, the keys are successivelydepressed to interpolate the desired data. Inthe present maat 0", it is also clear that the opening of the WI relay contacts prevents` the closing of the impulse circuit to the tape punch clutch magnet 280 when cam contacts CI close, noting that Y| contacts in this impulse circuit are closed if the key is held depressed. Y

Thisprevents a repetition o! the setup of the Z relay coils and a repet operation 'of the tape perforator.

When the depressed key is released, Y deener- |gizes to `open YI contacts and to open the Y2 contacts. The opening of the Y2 contacts causes f the Wrelay to deenergize and shortly after the Y| -contacts open the Wl contacts close. Hence,

' chine ritwill be assumed that this consists of 75 the circuit to the tape clutch magnet 280 is Still open and an impulsecan be sentto the latter only by a repeat key depression.
