This inventionrelates to mechanism normally operated from a keyboard and has for its object to provide a simple method and means of connecting two such machines so that the operation of the keyboard on the one machine is caused to operate a second or other machine connected to the machine of which a keyboard is operated, particularly with the object of incorporating in each machine such mechanism as will enable the actual connection between the machines tov be of the simplest possible nature. I

' Another object is to connect a typewriter withvanother normally key operated machine such as a perforator, and a further object is to connect relay opera-ted machines, such as typewriters to punch machines such as are employed for perforating statistical record cards. y

In the connection of machines which have keyboards of equal size it is a simple matter to provide connections from the keys of the one machine tothe keyboard of the other, but where the keyboard of one machine is 5 larger than the keyboard of another it is necessary to utilize combinations of keys on the smaller keyboard in order to producein the machine with the smaller keyboard all the ciphers of the larger keyboard.

One way of connecting a larger keyboard to a smaller keyboard is to directly connect the keys of the smaller keyboard and then to employ two connections from each of the other keys on the larger keyboard so that each of the keys on the larger keyboard in excess of the keyson-the smaller keyboard has connections to the smaller keyboardcorresponding to the code employed. 7 If the combination of two keys on a smaller keyboard are utilized to represent keys on the larger keyboard in excess of the keys on the smaller keyboard there will have to be two connections for each such excess keys.v

in accordance with the present invention, the keys of the smaller keyboard or extenr sions thereoi are CllSPOSGCl across the keysor extensions thereof of the larger keyboard and selecting devices are employed on 'the' tively.

larger keyboard in excess of the keys on the smaller keyboard directly selects the desired combination in the smaller keyboard.

In order that the nature of this. part of the invention-may be more clearly understood an example of the employment of the invention as a means of connecting the keyboard of a typewriter to a keyboard of a statistical card punching machine will now be ;'described. a V I -1 4 r I The keyboard of a punching machine comprises but twelve numeral keys. and thekeyboard of an ordinary typewriter. twenty-six alphabetical keys, and ten numeral keys.

, Now it is desired-to connect the alphabetical keys of the typewriter to the keys on the punching machine, so that a card will be perforated according to a code in which but the twelve keys are used individually or combined to perforatethe card in a single column to represent all the letters of the alphabet. I Such a code is in itself well known and is generally stated to comprise the employment of one key with each of thevothers toattain the desired selective combinations. One suchcode isas 'followskv f-i A The key 12 represents the letters Z and X. The keys, 11,.0,,1 2, 3, 4, 5, and6 represent respectively the letters A to H, the key 7 the letters I or J, the keys 8and 9 respectively .the letters K and L. Then to obtain the re maining letters ofthe alphabet combinations such as the following are chosen v V The keys 12 and 11 are used for the letter ,The keys-12 and 0 for the letter N and the key 12 is used with the letters 1 to 6 to produce the letters 0 to T respectively. The keys 12 and 7 are employed to prepresent the lettersU or V and the key 12 withthe keys S V respecf and 9 to represent the letters W and Y To connect keyboard with theialphabetical keys ofa typewriter the typewriter keys are provided with displaceable, for instance, hinged 'members, one member forv each key; and in a plane lying across the 'displa ce- ,able members and in. juxtaposed position thereto are arranged members, for instance,

bars which are moved by the displaceable mem'berswhen moved about their hinges.

The machine having the large keyboard may conveniently be referred to as the master machlne and the punching machine may conveniently be referred to as the servant machine. Then it may be stated that the depression of a key on the master machine, causes through suitable intermediate mechanism, a rocking of a hinged member (all of which are preferably arranged in one plane) into engagement by the hinged member of the bar or bars corresponding to the keys of the servant machine.

Each of the bars corresponding to the keys of the servant machine is provided with a selector device so that the hinged member of the master machine moves only the bars of the servant machine corresponding to the alphabetical key depressed. To this end each bar may be provided with adjustable sliding members disposed and arranged so that each hinged member engages only the bar or bars required to be selected to operate the servant machine.

Where the combination is definitely known, the selector members may be, in fact, fixed members, for instance, lugs integrally formed with the bars.

In the employment of the code already stated, the bar corresponding to the key 12 on the servant machine will have a selector lug for connecting up the hinged member of the key Z and another lug for engagement on op eration of the key X. There will also be on the bar of the key 12 of the servant machine a lug for operation by the hinged member of the keys M to Y so that the bar corresponding to the key 12 is moved as a result of depressing any one of the said letters of the alphabet but hinged members operated as a result of depressing the alphabtical keys M to Y will also engage the lugs on the bars representing the numerical keys on the servant machine, 11, 0, 1 to 9, to produce the combination above stated.

The bar 11 will be provided with a lug for operation by the hinged member of the key A of the master machine and the bars 0 to 9 will have lugs spaced in staggered rela-' tion for engagement by the hinged members corresponding to the alphabetical keys of the master machine B to L.

In such an arrangement there are only as many connections as there are keys. on the keyboard, the hinged members being, in fact, extensions of the keys on the master machine and the bars being extensions of the keys on the servant machine. These two sets of members lie across one another and the lugs above mentioned provide the selector devices.

Generally speaking, it is convenient to arrange the bars at right an les to the hinged members but another smaller angle may be employed according to the design of the connection required.

Conveniently, each of the bars corresponding to the keys of the servant machine are part of a parallel ruler system so that a similar displacement of the bar occurs wherever the selector lug is disposed in other words, whatever part of the bar is engaged by a hinged member. This lateral movement of the bar may conveniently be employed to produce longitudinal displacement of a. rod the ends of which in turn form actuating plungers of a flexible means, for instance, a Bowden mechanism communicating the effort to the setting devices of the punching machine.

This invention may be carried out in various ways, but one construct-ion according thereto is diagrammatically illustrated by way of example in the accompanying drawings in its application to a relay operated typewriter for instance, a Mercedes machine, which is coupled to a relay operated punching machine.

In the drawings Fig. 1 illustrates in perspective the translat-ing device and the mechanism associated with one-key of the punching machine;

Fig. 1A is a detailed perspective View of a part of the translating device shown in Fig. 1.

Fig. 2 is a cross sectional elevation of the typewriter showing the key actuated type mechanism and the translating device;

Figs. 3 and a are respectively a rear elevation and a plan of the translating device;

Fig. 5 illustrates the connection between the back spacing key on the typewriter and the translating device, and

Fig. 6 shows the connection between the space bar on the typewriter and the translating device.

In the construction illustrated in the drawings the typewriter comprises for each key 1 a key bar 2 extending inwardly of the machine substantially in a horizontal position and carrying a vertical latch member '3 normally lying over a lug 4 on an arm 5 hinged to a pivoted intermediate lever 6, the arm being held in substantially horizontal position by a spring 7 and carrying a nose 8 which is brought into engagement with a continuously rotated toothed member 9 usu ally referred to as a. roller, as a result of the catch 3 pulling the arm 5 down by engaging over the lug tt when the key bar 2 is rocked downwardly as a result of depressing the key 1.-

As a result of bringing'down the arm 5 causing the nose 8 to engage with the roller 9, the arm is brought forward by the roller rotating and the arm coming forward rocks the intermediate lever 6 about its pivot this lever being connected with lost motion to a type bar 10. Thereby the type is brought into operative relation with the platen of the machine (not shown). 7

New in order to connect this sort of machine to a statistical card perforating machine, for instance, as described in Thomas U. S. patent application Serial No. 419,974,

the intermediate lever 6 of the typewriter may be extended conveniently belowits pivot to provide an operative rocking extension member 6a moved as a result of depressing the respective key. J

In association with the extension 6a of the intermediate lever a push-trod 12 may be employed and at theback of the machine conveniently inthe form of a'unit'structure is arranged a frame'carrying vertical depending hinged members 13 one for each push rod 12, that is to say, one for each alphabetical and numeral key of the typewriter, the frame carrying on its lower part twelve horizontally disposed laterally movable bars l lserving to operate rods 16 the ends of which are guided in. a plate or bracket 17 "carried by the unit structure.

Each bar His connected to its operating rod 16 by means of a parallel ruler mechanism comprising bell cranks 15 and 15a connecting the parallel bars 14: with corresponding bars 14a. The operating rods 16 are connected to the bell cranks 15 so that when a bar 14- is moved laterally, the corresponding bell crank 15 also moves and actuates the 7 rod 16.

The pushrods 12 may abut directly against the intermediate members 13 as indicated at 1260 in Fig. 2, but in some cases, it'is desire able to provide a reducing lever system between the push rod and the lever 13. 'To this end the push rod may abut against a finger 13a of a plate 13?) carrying'a pin 130 which in turn abuts against the end ofthe hinged member 13. The plate 136 is pivoted at l3cland the push rod'1 2 abuts against the finger 13a at a greater radial distance from the centre 13d than the radial distance be tween the pin 13c and the centre 13d. i

A translating device comprising hinged members and displacealole bars according to the invention disposed as above described permits the dual operations to be performed without any additional service whatever being thrown on the keys of the master machine. The additional work is done by the power operated rollers.

Each hinged member 13 abuts against a lug '18 on one or more of the bars 14 in accordance with the code to be used; For example, the hinged member 13 corresponding to the key A of the typewriter will engage with the lug 18 on the bar 14 corresponding to the setting member for the punching machine which is adapted to perforate a hole in the 11 position on the card, whereas, as already explained the bar corresponding to the key 12 on the servant machine will have a lug 18 against which bears the hinged member corresponding to the key Z on the type writer and also another lug for engagement with the hinged In order to prevent confusion in'Fig. 1 only two bars have been illustrated and it will be seen that the hinged member 13 to the extreme left of the figure, engages with a lug 18 on one bar only, whereas the hinged member in the centre of the figure, engages -with lugs 18 on twoof the :bars.

gages a'lug 18 on one of the bars 14 arranged corresponding to the code, e. g. such as already explained. Therebya particular bar is displaced laterally and the end of the oper dating rod 16 projected through the guide plate 17 at the end of the structure. The structure may include combplates 19 for maintaining the hingedmembers separate from oneanother and for locating them accurately on the different lugs of the bars. according to the code employed in translating the characters of the one machine to the characters of the other. 1

Connected to the guide plate 17 for the operating rods 16 is'a bed plate 20 carrying the nipples of Bowden cables 21 connected to the operating mechanism of the perforating machine. In Fig. 1 one key 22 of the perforating machine only is illustrated together with its associated mechanism which is shown asbeing of the'kind' described in the specification filed with co-pending U. S. patent application Serial No. 516,301 entitled Improvements in mechanism for perforating. statistical cards filed in the names of Arthur Thomas and George Craig.

member for the typewriter key X.

As shown in Fig. 1 the Bowden cable 21 V abuts against a bell crank 23 'co-operating with a pin 24- projecting from the key bar 25. The key bar 25 has a downwardly extending lug 26 and when moved longitudinal- 1y by the operation of the Bowden cable 21 disposes the lug 26 so that it registers with a notch 27 in an intermediate bar 28, whereby said bar can rise until an eccentrically mounted disc 29 carried thereby engages with a continuously rotating toothed roller 30. The rotation of the toothed wheel 29 imparted thereto by the roller 30causes depres-' sion of the intermediate bar 28 and this bar then depresses a plunger 31 connected to a Bowden cable 32 of which the other end actuates a bell crank 33, thereby setting a set bar 34 for the corresponding punch.

The punch key may by suitable mechanism be operated from a special key on the typvwriter added to that'machine for the urpose of operating the perforating mac ine ployed to automatically actuate the punch key of the'card perforating machine. There by without any special manual operation on the master machine the carriage on the perforating machine, if constructed according to Thomas U. S. patent application Serial No. 419,974, new l at-ent No. 1,858,174, is returned to initial position thereby clearing th at machine and resetting connected machine.

In such form of typewriter machines star type is provided with actuating mechanism exactly the same as any other type, that is to say, an intermediate lever, of which the arm. disposed to engage the roller is depressed by the totalizer, there beingno key for operating the star type. Thereby, as result of a correct clearance of the totaliner the star type intermediate lever is rocked through the agency of the roller and its type bar brought into operative relation with the platen of the machine. In accordance with this invention the intermediate lever may be providedwith an extension in the same manner as intermediate levers of the alphabetical keys according to this invention, which extension is operated with a push rod (see Fig. 1) suitably connected by a bar in the translating device for operating the punch key, thereby a simultaneous return of the carriage on the master and servant machines is obtained.

The connection between the intermediate lever for the star type bar and the carriage return mechanism in the punching machine is illustrated in Figure 1, in which the push rod peratcd by the extension of the star type lever is indicated at and abuts against a hinged member 36, which is similar to the hinged member 13. This hinged member does not co-act with one of the parallel bars 14., but bears against one arn'i 37 of a bell crank pivoted on a vertical 38. The other arm 39 of this bell crank abuts against a collar 40 on a rod 41, of which one end co-operates with a Bowden cable 42. Thus when the typewriter accumulators are cleared the star type mechanism comes into operation and the push rod 35 is actuated, thereby turning the hinged member 36 in an anti-clock wise direction about its pivot, and causing arm 39 of the bell crank to push the collar 40 together with the rod 4'? to the in Fig. 1.. therebyactuating the Bowden cable 42, whichin turn causes the operation of the punches and simultaneously the return of the rod 16 is in alignment with the parallel 14a, or on the other hand, the pin 160.- can be moved in to the other arm of the slot 167),- in which case no movement will be transmitted to the rod 16 when the parallel bar 14 is actuated. The rod 16 and the parallel bar 1460 are in the nature of a toggle, which when the rods 16 and bars 14a are in alignment, forms a connection between the master machine and the servant machine, but when the inner end of the rod 16 carrying the pin 16a is moved into the other arm of the slot 16?), the movement oi the bell crank 15 produced by displacement of the bar 14 on depression of a key in the master machine is idle as regards transmission to the servant' machine. This displacement of the pins 16a can be eii ected by an automatic control suitably disposed for disconnecting the translating device, so that the master and servant machine can work independently;

the perforating machine is usually only required to operate for a part of the travel of the typewriter carriage, this disengaging mechanism is conveniently controlled by the typewriter carriage. To this end ll the opcrating rods are engaged by a. shutteror hinged flap 44 pivoted on a rod 45 and serving when rocked to move all the rods 16 into alignment with the parallel bars 14a. A short arm 46 is attached to the rod 45 carrying the shutter 44 and this short arm 46 is connected by means of a link 47 to an arm 48 mounted on a spindle. 49 of which the other end carries an arm 50 having mounted thereon a pin 51 which engages with a cam track 52 in the form of a bar on the carriage of the typewriter. This cam track is provided with recesses 53 disposed at intervals along its length and as the carriage travels the pin on the arm 50 will enter the recesses under the action of a spring 54 attached to the arm 46 on the shutter spindle 45. The upward movement of the arm 50 caused thereby permits the spring 54 to rotate the shutter and thereby move the rods 16 out of alignment witn the bars 140. thereby disconnectin the translating device.

The cam track or bar 52 is removable so that cam tracks of different contours may be used and to thisendthe bar is slotted at 5% and these slots engage with pins 5212, thumb screws being arovided to secure the bar in place.

In order that the carriage of the perforating machine may be skipped at specified points of travel of the carriage of the master machine,.the latter is provided with latches or dogs of which one is shown at 55 in Fig. 3.

A spindle 56 carries an arm 57 having an upturned nose 58 which engages with the latch 55 as the carriage travels. The spindle 56 also carriesa long downwardly depending lever 59 of which the lower end abuts against a collar 60 on a push rod 61 of which one end co-operates with the Bowden cable 62. As the carriage travels towards the right in Fig. 8, the up-turned nose 58 on the lever 57 engages with the inclined surface of the dog 55 and the lever 57 is therefore depressed. Consequently, the lever 59 is turned and pushes the rod 61, thereby actuating the Bowden cable 62 which is connected to the space mechanism for the punch carriage.

On the return of the typewriter carriage the vertical face of the dog engages with the up-turned nose 58 and is turned about its pivot 55a against the action of a spring (not shown) so as to swing clear of and over the nose 58. The rod 61 is returned by means of a spring 63.

In addition the back spacing mechanism-of the servant machine may be controlled automatically from the master machine. To this end, a back spacing key 64 on the typewriter which is pivoted at 65 overlies a pin- 66 on an arm 67 secured to a spindle v68, to the other end of which is secured a downwardly depending arm 69, which is forked at its lower end so as to straddle a push rod 70, to which is secured a collar 71 against which abuts the forked lower end of the arm 69.

As shown in Fig. 4 the push'rod abuts against a hingedmember 72 which actuates one of the parallel bars 14 in the same manner as the hinged members 13 actuate the parallel bars 14. A spring 7 3 abutting against a collar 74 of the push rod 70 serves to return the push rod. The parallel bar 14 which is actuated by the push rod 70 operates through a rod 16 Bowden mechanism'21 connected to the back spacing mechanism of the punching machine, which may be of any desired form.

The space bar on the typewriter may also be connect-ed to the space mechanism on the punch carriage. To this end a push rod 75, shown in Figs. 4 and 6, may be employed'to actuate a hinged member 13 and parallel bar 14 in the manner already described. As shown in Fig. 6 the space bar 7 6 of the type writer is mounted on two arms one at'e'ach end, of which one 77 is shown in Fig. 6'.

, These arms are pivoted between their ends as at 7 8 and are connected by a bail 7 9. Engaging with the upper edge of this bail is a hook 80 on a link 8101 which the lower end is pivoted to one arm 82 of a bell crank pivoted at 83. The other arm 84 of this bell crank is forkedat 85 so as to straddle the push rod and abut against a collar 86 secured thereto. Thus when the space bar? 6 is depressed the bail 79 is raised and lifts the link 81, thereby turning the bell crank 82, 84 in a clockwise direction, so as to push the rod 75 towards the right in Fig. 6, thereby actuating a corresponding hinged member and parallel in relation to the translation of the charac ters produced by operating alphabetical keys into perforations on a statistical card. Such machines also have a row of keys for operating type bars for printing members.

In the transmission of characters printing from these numeral keys on a typewriter machineto a perforating machine operating on a card having only two columns available for units items) it may be necessary to provide for means for transmitting numerals into hundreds position. In the employment of statistical cards in this manner of which the columns have rows numbered 0-9 it is usual to employthe space above the 0 corresponding to the 12 and 11 positions as a means of' indicating the hundreds. For instance, the 12 position in the tens column is used to represent one hundred, the 11 position in the same column to represent two hundred and the 12 position in the units column to repre-' sent three hundred and the 11 position in that column to represent four hundred, whilst clearly the space above the 0 in such cards maybe further divided up to show other numerals in the hundreds denominaition. As there are only two available columns on the card it is necessary to cut out the perforating machine when the. hundreds number key is being depressed in the typewriter, because there is not a hundreds column on the card.

To this end the control shutter 44 previous)- ly referred to as operating on the extensions 16 of the operating rods of the translating device is controlled so that while the hundreds numeral is being typed the translation is held up because there is not a'hundreds column on the card. Then, on the printing of the tens number in the typewriter the shutter 44 must be released in order that a transmission from this numeral is made to theperforating machine.

As the machine is usually employed with .a partlcular card form the shutter 44 is conveniently controlled by the cam bar 52 for the purpose of holding up the translation when the hundreds key is depressed on the typewriter.

It is now required to indicate on the card the hundreds number. To this end the typewriter machine is provided with special keys corresponding to theO, 11, 12 positions on the card which are connected'to displaceable bars which are added to and form part of the translating device. These special keys may conveniently be referred to as the 0, 11, and 12 keys ofthe typewriter. As shown in Fig. 1 and more particulary in Fig. 1A, each key is connected to its corresponding bar of the translating device by Bowden mechanism 87 through the agency of an operating plunger 88 notched at 880 to engage over lever 89 pivoted on the end of an operating rod 14a connected by a bell crank 15a to a parallel bar 14 carrying lugs 18 co-operating with levers 13. Thus, if one of said special keys is depressed its lever 89 on the operating rod will be rocked'clockwise as shown by "the arrow A in Fig. 1A.

At this end of all the operating rods 14a is a spring controlled pivoted flap 90 pivoted on a vertical axle 92, which is mounted in the translating device frame substantially at right angles to all the rods 14a. The free edge of the flap 90 is arranged to work in elongated slots 91 cut in each of the rods 14a, this free edge normally abutting the ends 41a of, the slots 91 under the action of the spring controlling the flap 90, so that movement of any rod 14a from the keyboard of the machine rocks the flap 90 in the direction of the arrow B against the tension of its spring.

It will be seen that the elongated slots 91 ensure that other rods 14a, which are not moved, will not be operated by this movement of the flap 90.

In order that the respective levers 89, when rocked, may co-operate with the flap 90, they are each notched at 89a to egage the free edge of the flap and form thereby a connection between the flap 90 and the rod 14a, to which ,the lever 89 is pivoted. Consequently, if the flap 90 is rocked, this rod 14a will be moved to actuate the set bar 84 connected thereto.

Thus, depression of one of the special keys on the typewriter, after the cam bar 52 has .held up the translation by rendering the translating device inoperative when the hundreds digit is typed, and has re-connected the translating device when the typewriter carriage is in the tens position, will connect the associated bar 1464 to the flap 90 with the result that when a tens key for typing a digit in the tens column is operated, the rod 14a corresponding to the special key and that corresponding to the particular tens akey', will be actuated simultaneously, so that both the hundreds and the tens digit will be set up together in the punching machine.

The present invention provides an effective means of connecting a machine of the Mer- -cedes relay operated type with a punch machine for statistical cards and if a. perforating machine for statistical cards as described in Thomas U. S. patent application Serial No. 419,974, now Patent No. 1,858,174,

is employed there is a clearing of both machines as a result of depressing the special key provided according to the invention on the Mercedes machine for actuating the punch key or its associated operatives in the punch machine. 7

The carriage in the Mercedes machine is automatically returned to initial position and as described in Thomas U. S. patent application No. 419,974, now Patent No, 1,858,- 174, operation of the punch key causes return of the carriage to initial position and in operation by actuation of what are known as the alphabetical keys of the keyboard, a statistical card is perforated without in any way interfering with the numeral keys of the Mercedes which operate counters and print combined. Moreover, the device may be emn ployed for combining the operatives of one machine with the operatives of another machine of a kind other than those which are controlled by a keyboard the essential feature being the simplicity of the translator device which only involves as many connections as there are operatives in the two machines required to be connected.

Further, it may be mentioned that the invention comprises also the employment of two translating devices actuated from a single machine whereby a plurality of machines are controlled from a single pair of machines, and in certain cases a single translator may be employed for operating two sets of machines for instance, by employing both ends of the operating rods of the translator.
