a 11:) Claims. (c1.164 113) This invention relates to a combined typewriting and card perforating machine, and particularly to means for coupling the typewriter and the card-perforator for joint operation.

The invention is herein described and illustrated as applied to an Underwood typewriter in combination with 2. Powers key-punch, said keypunch being herein called the card-perforator.

These machines are coupled for the purpose of producing a perforated record-card simultane- I ously with the typing of the record upon a worksheet in the typewriter. As is well known, these cards are used in making groupings, analyses, tabulations, etc., of the items indicated by perforations in the cards. A line of data under form headings on the work-sheet may include portions which need not be transferred to the record-card.

Therefore, while said portions are being typed, the perforator must be inactive.

A feature of this invention is the provision of improved couplingmeans whereby the joint operation of the typewriter and card-perforator may automatically be suspended and resumed at positive predetermined intervals without requiring the attention of the operative.

The card for use in a perforating machine is designed for forty-five denominational columns, each to have space for twelve holes. Ten of the hole spaces in each column are for the numerals. Above the numeral or digit spaces in each column, are two extra spaces, which are useful in grouping operations, coding, etc. These extra spaces are also combined with numeral spaces to represent alphabetical characters and other symbols. It will be understood that a space hecomes eflective when a hole is punched therein.

The blank card is automatically fed into theperforator so that its five hundred and forty hole-spaces are in register with a nest of five hundred and forty punches in the perforator;

Said punches co-act with a perforated die-plate beneath the card to punch holes in the card. During the punching operation, the die-plate and card are raised. This raises all the punches except those over the spaces to be perforated. These are held down by rods or setting pins which were previously depressed and latched by operation 01 the perforator-keys. There is one setting pin in line with and over each punch. As the card and die-plate are-raised, these helddown punches penetrate the card and punch a hole therein. A spring-propelled carriage having twelve key-actuated pin-setting plungers traverses the forty-five denominational columns of setting pins from left to right in escapement 'perforator-keys.

.the wrong card columns.

controlled denominational-selecting steps so that one column is set up at a time. When the .carriage co-acting with the perforator-keys has traversed and set the pins so that the record holes may be punched, a punching cycle is initiated, during which a blank card is fed in and punched according to the pin-setting. While the blank card is fed in, the card punched in the preceding cycle is ejected. The pin-setting carriage is then returned manually and this return automatically restores to normal position the pins which had been set. Previously to the present invention, the typewriter and perforator were coupled for joint operation by means which included an electric cable joining typewriter-key-actuated electric contact devices on the typewriter with electromagnetically operated devices for actuating the Thus when a typewriter-key is depressed an electric circuit to and including one or more of the electromagnetic devices is established by closing said contact devices and one or more perforator-keys are "actuated, it being understood that some characters are represented by two holes. With this arrangement, a foot pedal is provided whereby electric connection between the perforator and typewriter may be interrupted, with the result that during this interruption the perforator is inactive while the typewriter-keys are operated in typing portions Through inopportune connection or disconnection of the two machines by the operative in using the foot pedal, the columns on the work-sheet will get out of register with the corresponding columns on the card, and holes will be punched in An error of this kind is not apparent in most cases, except by a painstaking and tedious comparison of the perforated cards with the work-sheet.

What is provided therefore, by this invention, in the preferred form herein described and illustrated, are positive coupling means whereby the typewriter-carriage in its movements drives and automatically controls the movement of the cardperforator pin-setting carriage, said coupling means including devices for automatically suspending and resuming the joint operation oi the typewriter and card-perforator, so that the lata ter may be inactive while data not required to be punched on the card is typewritten. The feai'oratcr carriages is disclosed in theco-pending application of Alfred G. F. Kurowski, Serial No. 48,723, filed August 7, 1925, (now Patent No. 1,683,979, dated September 11, 1928) wherein are showna rack on'each carriage, meshing at all times with an intermediate pinion, and a modified typewriter escapement-mechanism .for moving the typewriter-carriage in steps of of an inch,- which is the longitudinal spacing of the holes or columns on the card. The invention disclosed in 'tatably mounted on a stationary spindle.

said co-pending application was for the purpose of tively connecting the two carriages and typing a printed heading on cards, which were then inserted in the peri'orator and punched from the pin-setting made coincidentally with the typing.

In the present invention,-it is required and provision made that, while the typewriter-carriage moves in steps of letter-space extent, the cardperiorator pin-setting and denomination-selecting carriage shall move in steps of denominationspacing extent.

To this end, there is provided on the typewriter-- carriage, a rack which meshes with a pinion ro- Coaxial with said pinion and coupled therewith on the same spindle in a manner to be set forth is a larger pinion which meshes with a rack 'on the perforator pin-setting carriage. The spacing movements of said carriages are proportionate to their respective pinion diameters. No change is required in the typewriter escapement, but, as

set forth in the aforesaid co-pending application,

the propelling spring and escapement-mechanism for the perforator-carriage are dispensed with and may be omitted from the perforator, because said perforator-carriage is controlled by the typewriter carriage and its escapementmechanism. The two aforesaid pinions are devised so that one of them slides into and out of engagement with the other in the'manner of a clutch.- Both pinions have interlocking clutchteeth and the slidable pinion is actuated by a .spring in one direction, and, in the opposite direction, by a disconnecting lever having one arm bifurcated and engaging an annular groove in said slidable pinion. The spring normally keeps the pinions coupled. A series of cam-blocks with flat dwells of varying extent is mounted at intervals on the upper side of the coupling rack on the typewriter-carriage. These cam-blocks, one at a time, and successively as the typewriter moves in a letter-feed direction, encounter an arm on the aforesaid disconnecting lever, and

actuate said lever to disconnect the pinions and keep them disconnected while the typewritercarriage travels the extent oi the dwell on the particular cam-block which is in engagement. The length and spacingof the cam-blocks are determined by the form on the work-sheet in I relation to the form on the card.

. move, and said extension must yield until 'the' A spring-pressed one-way pawl is mounted on said arm to engage the cam-blocks and is'diverted and tipped by the cam-blocks during the return movement or the carriages. when the two pinions are disconnected, a spring-pressed extension on the disconnecting lever enters one of thecircumferentlaln'otchs provided in the pin-setting carriage pinion, and in this manner holds said carriage while thus disconnected from the typewriter-carriage. It is necessary that this extension of the lever be spring-pressed because it encounters one of the teeth between the notches as soon as the disconnecting lever begins to typewriter-carriage.

pinion has been sumcierftly rotated to allow the beveled-edge of said extension to slip into the notch.

The present invention retains and uses the key-actuated electric contact devices on the typewriter joined by a'cable to electromagnetic devices for actuating the perforator-keys. To completely suspend the joint operation of the two machines it is necessary, besides disconne'cting the carriages, that the electric connection between the machines be interrupted, else whenever a typewriter-key is actuated, a pin or pins will be set up in theperforator at the column where the perforator-oarriage stops when the two carriages are disconnected. If this column is to be skipped when joint operationis resumed, it would contain an unwanted pin-setns.

Provision is made, therefore, of means for interrupting the electric connection between the two machines when their carriages are disconnected. Said means consist of a pair of springpressed contacts which are arranged to open when'the pinion disconnecting lever is actuated.

- These contacts are connected in the common lead to the eiectro-magnets to make and break the circuit for said magnets.

Provision is also made of means for manually disconnecting the two machines so that the typewriter may be used alone in regular typingwork. This is done by providing the disconnecting lever with a handle and suitable means for holding the lever in disconnected position.

d When the carriages are moved'forward in letter-feed and pin-setting steps, intervals may occur,'a.s already explained, during which the typewriter-carriage moves, but the perforator-carriage is stationary. During such intervals the coupling pinions are disconnected. Thus the typewi'iter-can'iage moves through a greater number of steps than the periorator-carriage. In returning the carriages. the perforator-carriage reaches its starting point and encounters a I stop before the typewriter-carriage, because, during the return movement, the pinions are not disconnected at intervals, due to the pawl on the disconnecting lever being diverted by and trailing over the cam block.

It is necessary, therefore, that the length of the coupling rackon the'perforator be of such extent in relation to its pinion that the teeth of said pinion may escape from the end of said coupling rack when the perforator-carriage has returned to its starting position. The typewritercarriage may then be further returned until its starting position is reached. A spring suitably applied to the perforator-carriage and its rack presses said rack toward and against its pinion, so

that the pinion will pick-up the rack as soon as the carriages are to start forward again. At the end of the return movement of the perforatorcarriage, this spring will be slightly stressed, the rack moving a slight distance beyond the normal stopping point before the teeth of the pinion escape while the typewriter-carriage is completing its return movement.

It has been explained how the pawl on the disconnecting leveris diverted and tipped by the cam-blocks during the return movement of the Means are provided, therefore, in this invention for restoring the pawl to its normal position relative to said disconnecting lever.

at the beginning of the line. Such a cam-block This is necessary when a carriage disconnecting cam-block is in engagement is provided, therefore, with an elevated surface which engages a stud in the disconnecting lever. At the end of the return movement of the typewriter-carriage, the pawl end of the disconnecting lever is thereby raised to enable the tip of the pawl to clear the cam-block, so that said pawl may swing back to its normal position.

Other features and advantages will hereinafter appear.

The platen is revolubly mounted within a carriage 22 which moves upon carriage rails 23 and 24 on the main frame 25. A work-sheet 2| is introduced at the rear of said platen and fed around it by the usual means. Said carriage is urged from right to left by a spring motor 26 on the typewriterframe. A strap 21 connects the spring motor to the carriage. The type-bars engage a universal bar 28, movable rearwardly,-to actuate an escapement-rocker 23 carrying escapement- .dogs 30, which co-operate with the teeth of an escapement-wheel 3| to effect step-by-step letter-space movements of the carriage at the actuation of each key or space-bar 32. The escapement-wheel is rotated in one direction by a pinion 33, which is driven by a feed-rack 34 supported by arms 34 pivoted to the carriageframe.

that connects with a rocking bar 31 carrying a series of stops 38. By depressing the tabulatorkey these stops move into the path of a carriagestop 38, and simultaneously the carriage feedrack 34 is raised from engagement with the pinion 33, so that the spring motor 26 may effect column skipping or tabulating.

Power-driven means for returning the typewriter-carriage may be of the'type disclosed in the co-pending application of Alfred G. F. Kurowski, Serial No. 41,507, filed July 6, 1925 (now Patent No. 1,679,727, dated August 7, 1928). Said means (see Figure 12) include an electric motor 40 suitably geared to a clutch-member 4| which is keyed to a shaft 42 on which is slidably mounted a clutch-pinion 43 having teeth 44 to engage said clutch-member 4|. The clutchpinion 43 is operatively connected to a springpulled latchlink 45 which servesto keep the clutch disengaged. Said latch-link 45 may be tripped to engage the clutch by means of a lever and key 46 conveniently located near the typewriter keyboard. Said lever when operated raises the forward end of the latch-link until a latching notch therein escapes from a holding edge. A spring 45, then pulls the latch-link rearwardly to effect engagement of the clutch. When the latch-link is tripped to engage the clutch, a rearward extension 41, connected to said latch-link by means of a short shaft 41, serves to close a circuit to the motor by means of suitable contacts within the switch-box 49, thereby starting the motor 40. The clutch-pinion 43 meshing with a rack 48 mounted on the typewriter-carriage then drives said carriage in its return movement. Said rack is mounted and arranged to actuate a line-spacing mechanism 4|! before it picks up the carriage. When the carriage reaches the end of this return movement, a cam 50 on the carriage rocks the shaft 52 by means of a settable dog 5|. This disengages the clutch-pinion 43 by means of the arm-and-link connection 53 to the slidable clutch-pinion 43. At the same time the latchlink 45 is restored, the circuit to the motor is broken, and the motor stopped. v

A trip-key 54 is provided at the typewriter keyboard for starting an operating cycle of the card-perforator. Said card-perforator is the well-known Powers key-punch. This perforating cycle must precede the return of the carriage.

During this cycle a blank card 55 is picke from a stack 55 by means of a reciprocating picker 56 and pushed through a one-card aperture 51, and thence to feed-rolls 58, 59 and 60. These rolls carry the card into punching position determined by stops 6|. In this position the card overlies a die-plate 62 which may coact with punches 63,, as will be shown. The feed-rolls bear upon the card with limited pressure, so that they may slip over the surface of the card when it reaches the stops 6|..

The upper endsof the punches are guided by close fitting holes in a plate 64 supported by a machine frame A. The punches are prevented from falling through by having enlarged heads 65. The punches 63 are guided by having a working fit in a bar 66, and the die-plate 62, forming a part of a frame 63, after receiving-a,

card, is moved upward and presents the card to the punches. This effects perforation of the card when a punch or punches are held down. Punches not held down are carried upward by .the card. After a card is perforated it remains in place under the punches until another perforating cycle is initiated. At thebeginning of such a cycle the stops BI are withdrawn by cam devices, not shown, and the feed-rolls 60 are then free to pass the. card to rolls I50 and thence into a receptacle 6|.

Each punch, of which there are five hundred and forty arranged in forty-five denominational columns of twelve digit punches, has above and in line with it a pin 51 which may be pushed l'x down and latched, so that its lower end stops the punch as the card moves upward and is pierced thereby.

Each column of twelve pins has a latch-bar 68 provided with suitable edges to interlock with edges 69 on the pin 61 to hold said pin down when depressed. Each latch-bar and its associated twelve pins are devised to co-act in a manner well known in the adding machine art, so that a depressed pin or pins are restoredby depressing another pin or pins in the same column. When a latch-bar is withdrawn from a depressed pin, the pin is restored by a spring I0 which presses the pin-upwardly until a collar fastened-to the pin strikes a plate II. The lower end of the spring re-acts against a plate I2. Said plates II and I2 have holes which fit and guide the lower ends of pins, and said plates are fastened to bars 13 supported by the machine-frame A. The upper ends of the pins are guided by holes in plates I4 and 15 supported by cross-bars I6 fastened to the machine-frame A. The latch-bars 6B are slidably supported in the cross-bars I6 and are pressed against the pins by springs 11. Thus there is a bank of setting pins over the punches and wherever a hole is to be punched a pin is depressed and latched by its corresponding latch-bar 68.

To eilect setting of the pins, the perforator is ordinarily provided with a keyboard of twelve keys. These twelve keys correspond to the twelve hole spaces of each card column. Co-acting with said keys are twelve pin-setting plungers I8 arranged to traverse the bank of setting pins 61 in acarriage 19. Said carriage is retained and guided by rails supported by the machineframe A.

As shown in the aforesaid co-pending application, No. 48,723 relating to a combined typewriter .and card-perforator, the regular perforator-keys are replaced by solenoid-actuated plungers Ill. 'The solenoids I43 (Figure 3) are mounted within a box (Figure l), and the plungers are operatively connected to the pinsetting plungers by means of flexible push wires and bell-crank levers 82, to the horizontal arms of which the upper ends of the pin-setting plungers I8 are attached. The flexible push wires are enclosed in flexible sheaths 83. A universal bar 84 spring-pressed against the vertical arms of the bell-crank levers 82 keeps the pinsetting plungers normally up.

Each solenoid I43 is in a normally open electrical circuit which includes a source of'current and a pair of separated contact devices I44 (Figure 3). These contact devices underlie the typewriter-keys I5 and I6 and are arranged within a case III through the top of which extend insulated p1ungers186 by means of which the type' writer-keys when depressed close the contacts to energize the solenoids. When typing a character represented by two holes in the card, the corresponding typewriter-key closes two sets of contacts I (Figure 3), so that two solenoids are energized and two piris set. The wires between the contacts on the typewriter and the solenoids on the perforator are gathered into a cable 81.

The trip-key 54, like the typewriter-keys, is effective to actuate a solenoid I43 within the box 85. A plunger 88, by means of the flexible push wire within a sheath B9, is capable, when actuated by the solenoid, of operating a clutch mechanism, not shown, to start a cycle of the perforator. The details of this clutchmechanism and its mode of operation are shown in the patent to Lasker, No. 1,352,006, dated'September 7, 1920. The plunger 88 of the present invention replaces the controlling key shown in said patent to Lasker.

Operation of the clutch-mechanism connects the machine shaft 90 to a continuously rotating motor-driven disk, not shown. At the end of one revolution said machine shaft is automatically disconnected from the driving disk. During this revolution the feed-rolls 58, 59, 60 and 60 are rotated by means of the gear BI- on shaft 90. The frame 6! in suitable guides is moved up and down by means of arms 92 extending from the ends of a rocker-bar 93 pivoted at each end to the machine-frame A at 94. 'Said rocker-bar is rocked by means of an arm 95 projecting from the middlethereof, and which engages a groovedface cam 95 by means of a follower roll 91.

After the perforating cycle, return of the pinsetting carriage is eifected, in a manner that will be shown, by depression of the carriage returnkey 45 (Figure 12) and, during this return, pins 61 are restored by means described in the aforesaid co-pending application No. 48,723, relating to a combined typewriter and card-perforator. Said means include a roll 98 which is normally inefiective to operate the pin-restoring levers 99. Said roll 98 is mounted upon a lever I00 pivoted upon the pin-setting carriage and connected by a link I00 to another lever II, also pivoted upon the pin-setting carriage.

During the final movement of the pin-setting carriage said lever IN is rotated when avertical arm IIII thereof meets an extension I02 from the machine-frame A. Said arm llll is then caught and held by a latch I03 pivoted upon the pin-setting carriage. The roll 90 is thus clepressed and held in a positon where it is effective to actuate the pin-restoring levers 99 during the return movement of the pin-setting carriage.

Said pin-restoring levers in turn push the latchbars 68 endwlse to release pins that have been set. At the end of the return movement of the pin-setting carriage, the latch I03 when it meets an adjustable stop I04 is rotated and withdrawn from the arm IOI A suitable spring, not shown, then restores the lever IOI, so that the roll 98 thereon is raised out of engagement with the pinrestoring levers. I l

The perforator pin-setting and denominationdetermining carriage I9 is driven and controlled by the typewriter-carriage 22. To this end, a rack IOIi'is supported by means of brackets I01 upon the typewriter-carriage and meshes with a pinion I08. Said pinion I08 is coupled to a larger pinion IIO, which it may drive by means of the clutch-teeth III in both pinions. pinion H0 meshes with a rack II2 mounted on brackets I I3 projecting from the pin-setting carriage. Both pinions are revolubly mounted upon a stationary spindle II4, shown in detail in Figure 9. The spindle is reduced in diameter at its upper end to form a shoulder I I5, which, in con junction with a screw-head II6, retains the upper pinion H0. The lower pinion I06 may slide along the spindle, but is normally coupled to the upper pinion by means of aspring I09. A washer III is interposed between the spring and lower pinion with which it may freely slide} up and down, but said washer is prevented from turning by engaging a slot II8. Said spindle III is suitably mounted upon a platform II! of the card perforator (see Figure 2). i

The diameters of the pinions are proportioned so that steps of letter-space extent of the typewriter-carriage will produce steps of denomination-spacing extent ofthe pin-setting and denomination-determining carriage. A forward or pin-setting movement of the pin-setting carriage is from left to right, while a forward or letterfeed movement of the typewriter-carriage is from right to left. Thus the carriages move in opposite directions. The stepping movement of both carriages is controlled by the spring motor and escapement-mechanism of the typewriter, the escapement-mechanism and spring-motor of the perforator being dispensed with.

When it is desired to use the typewriter alone in regular typing work, the lower pinion I06 may be separated from the upper pinion IIO by means of a disconnecting lever I20 pivoted in a bracket I2I mounted upon the platform IIO of theperforator. Said disconnecting lever has an arm I20 bifurcatedto embrace and engage the lower pinion by means of an annular groove I00- therein and rolls I20". Said disconnecting lever may be manipulated by means of a handle I22 thereon, when it is desired to use the typewriter alone in regular typing work. From this handle extends a clip I22, which may be caught by the edge of the screw-head II6 to hold the lever in a position for disconnected pinions. When said pinions are disconnected, the connection between the typewriter-keys and perforator-setting mechanism also becomes inoperative, as will be shown. For the purpose of this invention, means are provided to automatically actuate the disconnecting lever before and after typing certain parts of a line on the work-sheet not required to be punched in the card. To this end, the dis-. connecting lever I20 is provided with an arm I20 carrying a spring-pressed one-way pawl or trip I24. Said pawl or trip has an inclined cam-face I24 by which it may ride over cam-blocks or tappets I25 and be lifted thereby during a letterspace movement of the typewriter-carriage to efl'ect the separation of the pinions, prevent the setting of the punches and establish a nonpunching setting zone, as shown in Figure 6.

It is'necessary to use a pawl on the disconnecting lever, because said lever must be disengaged from the cam-block at the end of the last step thereon. In this way the typewriter-carriage pinion does not rotate= while being reconnected to the pin-setting carriage pinion. This necessitates an abrupt disengagement of the disconnecting lever from the cam-blocks and is accomplished by having shear surfaces at the ends of the cam-blocks and at the escaping edge of the disconnecting lever. Said escaping edge must therefore be in the form of a tripping pawl so as not to vibrate the lever I20 during areturn movement of the typewriter-carriage.

The cam-blocks I25 vary in length predetermined by the number of letter-space distances the typewriter-carriage is to take while joint operation is suspended. Said cam-blocks have square stems I25, by means of which they are secured to the coupling rack I06 on the typewriter-carriage. These stems closely fit and extend through square holes I26, spaced in staggered arrangement in said coupling rack. A locking bar I21 rotatably mounted in brackets I20 and I29 (see Figure 4) and provided with a knob I30 and detent devices I3I secures the camblocks in a manner clearly shown in Figure 11. A quarter turn of the locking bar frees the stems of the cam-blocks when it is desired to withdraw the cam-blocks or rearrange them upon the coupling block I06.

When the disconnecting lever is actuated to disconnect the pinions, a rod I 32 pivoted to said disconnecting lever at I32 is thrust downward. This separates electrical contacts I 36 contained in a box I34 having a suitable slot I04 to guide said rod. Said contacts are in the common lead to the electromagnets (see Figure 3), and when separated the magnets cannot be energized when the typewriter-keys are actuated. Thus com nection between the two machines by means of the aforesaid disconnecting lever and camblocks. Joint operation is resumed when the escaping-edge of the disconnecting lever pawl drops oil the cam-blocks.

The work-sheet 2I in the typewriter, Figure 1, shows a form-heading beginning with a name. Lines entered under this heading begin with data not wanted on the card. In such cases when suspension of joint operation of the two machines occurs at the beginning of a line, a modified cam-block I36 is provided to effect disconnection of the .two machines. This camblock difl'ers from the other cam-blocks in having an auxiliary cam-surface I26 elevated above the regular surface I36 By means of a pin. III in the arm I23 of the disconnecting lever I20, this auxiliary cam-surface serves to disconnect the pinions, break the contacts I", and raise the pawl end of the disconnecting lever, so that I the tip of the pawl swings clear, and the pawl may resume the normal effective position from which it was tipped by the return movement of the carriage Neither the regular cam-blocks,

, yield until the pinion has been sufliciently rotated to allow the extension, which has a slightly beveled edge, to slip into the succeedingnotch. The clearance I30 (Figure 9) must be so proportioned Y that the under surface or edge of the extension meets the upper surface of a tooth in order that the extension may easily override the tooth and slip into the succeeding notch.

During the forward movement of the type-.

writer-carriage, the pin-setting carriage is disconnected and stationary at intervals, and thus the typewriter-carriage moves through a greater number of steps thanthe pin-setting carriage. But during the greater part of the return movement of the carriage, the disconnecting lever is inoperative, due to the pawl thereon being tipped by, and trailing over, the cam-blocks. 'Therefore, whenever there are intervals of disconnected carriages during the forward movement, the pinsetting carriage, during the return movement, will reach its starting point and encounter a stop before the typewriter-carriage. The pinsetting carriage rack H2 is of such length, therefore, that only the last tooth thereon is in engagement with its pinion when the pin-setting carriage has reached its starting position. One or two steps before this, the pin-setting carriage has engaged and stressed a spring I" fixed to the machine-frame A, and, as the typewritercarriage completesits return movement, this spring is stressed a little more by a slight further movementof the pin-setting carriage which occurs as the teeth of its pinion push aside said last tooth of the rack and escape therefrom. This results in a ratchet-like action'between the last tooth on the rack and the teeth of the pinion. As each pinion tooth escapes, said rack is pressed back toward and against the pinion, so that the pinion will readily pick as both carriages are to 5 art forward again.

;A stop I42 which backs up the spring at H2 prevents excess return movement of the pinsetting carriage. The linear pitch of the rack 105 and pinion I08 equals the letter-feed pitch of the typewriter-carriage. In order that the pinions, racks and the parts related thereto may not get out of register with each other it is necessary that the pinions I08 and III have the same number of teeth, and thatthe number of notches H0!- and the number of clutch-teeth lll equal the number of teethin each pinion. Thus one step of each carriage "is equivalent to a notchto-notch or tooth-to-tooth movement. The typewriter is mounted upon a suitable frame I" extending from and supported by the peri'oratormachine-frame.
