This invention relates to improvements in combined typewriting and accounting machines.

One of the features of the present invention is the provision of a structure in which is combined the functions of a typewriter and an accounting machine in such way that the device may be converted from a typewriter into an accounting machine, and vice versa.

Another feature of the present invention is the provision of such a structure in which the keys for actuating the typewriter and for controlling the setting up and printing of the computation printing means are all on a single keyboard, and the keys used for typing the numerals on the typewriter are used for setting up the computing machine parts corresponding to the same number as used for the typewriter, thus permitting of using the touch system (ordinarily taught for the operation of typewriters) for both the typing and computing devices of the machine.

Another feature of the present invention is the provision of such a structure in which both the typing and the printing of the items from the computation item printing type bars, are accomplished by separate devices in such a way that the decimal point of the computation item printing type bars or members prints at the same point or sighting position on the platen that the typewriting type bars would print if being used. In other words, the typing point for the typewriting type bars and the decimal point for the computation item printing type bars is the same.

Another feature of the present invention is the arrangement of the typewriter type bars and the computation item printing type bars in such way as to print on the platen at a vision point always visible to the operator except when type bars are actually in the operation of printing.

Another feature of the present invention is the provision of such a structure in which the items to be computed are set up and printed by computation item printing type bars actuated by the computing machine parts while the carriage is at a standstill, and are accumulated in regular sequence upon a register device.

A further feature of the present invention is the provision of means for efiecting an automatic transfer from typing to adding functions, with a disconnection of the devices which effect spacing or lateral movement of the carriage while the structures are in the computation item printing position, and with devices for preventing the movement of the typewriting type bars while in such position.

Still another feature of the present invention is the provision of means for accomplishing shifts of the structure from the typewriting to the computation item printing position and back again, alongwith means for disabling typewriting structures or computation item printing structures to prevent wrongful action thereof.

Still another feature of the present invention is the provision of means for accomplishing a shifting from typewriting to computing functions 1. by the use of the energy of the carriage moving spring.

A further feature of the present invention is the provision of a structure in which the typewriting and computation item printing devices are rigidly supported for their respective functions, with devices for effecting a relative movement thereof with respect to the carriage platen.

Still another feature of the present invention is the provision of a movable carriage and type- 0 writing type bars operable from normal typewriter keys for typewriting, along with a computing structure including computation item printing type bars operable from the same keys for the printing and accumulating of items of computation, and a ribbon mechanism by which a single ribbon may be employed for both typewriting and computation item printing operations, this mechanism including parts operated by the individual keys during typewriting and operated from the computing mechanism during computing.

A still further feature of the present invention is the provision of a structure of this type in which a single set of normal typewriter keys is employed for the typewriting and for the setting up of the items to be computed, together with devices for selecting the type of operation to be effected, and preventing a wrongful action according to the selection accomplished.

With these and other features as objects in view, as will appear in the course of the following specification and claims, an illustrative form of practicing the invention is shown on the accompanying drawings, in which:

Figure 1 is an upright sectional view showing the assemblage of parts for typewriting and computing functions. v

Figure 2 is a fragmentary horizontal sectional view with parts omitted for cleamess, and showing the general assembly of structures.

Figure 3 is a transverse upright sectional view substantially on line 3-3 of Fi 1.

Figure 4 is a fragmentary rear view showing 5 means for controlling the shifting of the structure from typewriting to computing function.

Figure 5 is a perspective view of other portions of the devices for shifting from typewriting to computing function.

Figure 6 is a detailed perspective view of a stirrup for connecting a setting lever with the correspondingkey lever.

Figure 7 is a detail showing the supporting of the universal bar.

Figure 8 is a detail showing a conventionalized restoring bar.

It will be understood that the reference to adding in this specification and claims is a designation of the effecting of computing as distinguished from simple typewriting, and that the Word includes the utilization of structures for performing other than simple arithmetic addition.

Since one of the features of the present invention is that of producing a permanent imprint of the descriptive phases (by simple typewriting) and of the numerical or computative phases (by printing), the reference hereinafter to printable element includes various surfaces and materials capable of receiving an impression, either from types with ink or ribbon transfer of pigment, or by the employment of other means for effecting a permanent impression.

In the drawings, the apparatus is shown as comprising a fixed frame including the cross members H), H, l2 and I3. A top plate l4 joins the upright side frames and cooperates with the rear portion l5 of the top plate for stiffening the fixed assemblage. It is preferred to close the rear of the structure by a plate "5.

This fixed structure supports a plurality of keys corresponding to normal typewriter keys. In Fig. 2 these keys are shown to be comprised in four banks and generally to correspond to a typewriter keyboard. In the illustrative form shown, there are ten keys in the upper bank, corresponding to types from 1 to 0. In the drawings, a single key lever is indicated, the others being omitted for clearness, but it will be understood that the other numeral keys are similar in arrangement, while the non-numeral or letter keys need not be provided with certain of the structures, as will be pointed out hereinafter.

The illustrated key 20 appearing in Figure 1 (being the key for 0) is mounted on a key lever 2| which extends rearwardly in the fixed structure and is supported by the general cross pivot rod 22 for all key levers, and is normally held in raised position by a spring 23 supported in the bar 13 of the fixed frame. This key lever has a pin 24 which engages with a forwardly extending end of a crank lever 25 pivotally supported in a stationarily supported cross comb bar 26 and connected at its upper end by a link 21 with one end of a typewriting type bar 28 which also is supported, as by the usual arcuate pivot 29, in an arcuate comb bar 30 forming a part of a shiftable assemblage, as will be described hereinafter. The typewriting type bar 28 normally rests upon the cross support 3| but is swung upward in the usual way when the key 20 is depressed, and enters between the guides 32 to print through the ribbon R upon a printable element located on the platen P of the carriage.

The downward movement of the key 20 during typewriting also causes a hump 200. on the lower edge of the key lever 2| to encounter a spacing universal bar 35 and move the latter downward. This spacing bar is connected in suita h ner (not shown) for actuating the lever 38 and thus the escapement ll of a ratchet wheel 38 which controls the movement of the carriage C in response to the pull thereon of a cable 39 which is energized by the carriage spring 40 (Fig. 3) in the usual way.

' Similarly, the downward movement of the key lever 2| depresses a ribbon universal bar II which is supported by arms l2 on pivots l3, and is connected by the links M to the levers 15 which are pivoted to the lower surface of the top structure i4, i5. The levers at their inner ends are connected to the ribbon controlling wires 46 and thus serve to raise the same in the guides 47 and to elevate the ribbon to printing position when a key is struck, and operate likewise upon the release of the key to cause the ribbon R to be brought to a lower position to expose the letter which has just been typed.

The shiftable structure comprises vertical side members 50 having extensions 5!, 52 at their bottoms, these extensions being cut away to pro vide downwardly open notches to receive the universal bars 35 and M (Fig. 1). The extension 52 supports two transverse rods 53 for guiding the threaded adjustable stems 54 of thin stirrups 55 (Fig. 6) which are pivoted at their upper ends to the setting levers 56 of the adding mechanism. Lock nuts 54a may be provided if desired, as shown in Figure 6 of the drawings, in order to maintain the adjustment. Each key lever 2| corresponding to a numeral key is provided with a setting lever 56 located substantially above it and connectable thereto by a stirrup 55 as will be described hereinafter. The ten setting levers 56 are supported by a transverse pivot rod 51 of the fixed structure.

This shiftable structure also includes the comb piece 30 and the upward extension 58 supporting the guides 32 employed during typewriting (see Fig. 3). The shiftable structure also includes the forwardly extending side bars 59 and the bridge connection 60 between the latter. The side bars 59 are supported by a plurality of bearing balls 6| for permitting easy forward and rearward movement of the shiftable structure. The carriage C is illustrated in Fig. 4 as having a member adjustably connected thereto at a suitably selected position and having an inclined end surface 65 for engagement with a roller 61 carried by a shifting lever 68 which is mounted by a pivot 69 on the top plate 15. This lever 68 is connected by a link in (Figs. 1, 4 and 5) with the center point of a toggle system including the link H which is connected by a pivot 12 to the fixed frame, a link 13 having a slot 14 receiving the pin 15 of a shifting stirrup comprising the upright portions 16 and the extension and connecting portions 11. The toggle is'normally pulled downward by a coil spring '18 connected to the fixed structure. It will be understood that the arms li of the shifting stirrup are spaced laterally of the adding and like devices. The lower ends of the arms 16 are supported by pivots 19 on the fixed frame, while the upper ends are bifurcated and have notches B0 to receive a transverse rod 84 supported by the members 50. The slot II in the link 13 receives a spring 8| which presses against the pin I5 and tends to force it toward the outer end of the slot 14.

The setting levers 55 are illustrated as of conventional design, each of them having a pressure piece at the rear end for engagement with a pin 9| in the preselector pin plate 92. It

will be understood that this preselector plate has as many rows of pins as there are columns in the capacity of the adding mechanism. In Fig. 2, ten such columns are indicated, and correspondingly there will be ten rows of pins 9I, each comprising ten pins, in the preselector plate 92. This preselector plate is supported for horizontal transverse movement step by step as the keys are operated, by mechanism not illustrated but well known in the art. Such preselector structures are shown in Landsiedel 1,078,- 358; Kottmann 2,034,345; Greve 1,707,303 and 1,897,932; and Siewert 1,957,617. The function of this structure is to permit the operator, by depressing the proper keys, to raise the corresponding pin SI and then effect a leftward movement (considered from the viewpoint of the operator) of the preselector plate 92 by one column, so that the next key operation will similarly set up a numeral for the succeeding column, etc., in known manner.

Cooperating with this preselector pin plate 92 is a corresponding number of adding racks 93 which are supported by a fixed comb bar 94 and a rod 95 for rectilinear forward movement under the action of the individual springs 96. The rearward end of each adding rack has a downwardly extending finger 91 for engagement with the preselected pin 9| which is presented in its path, and pivoted latching equipment 98 is provided for releasably securing the racks in the position shown in Figure 1, against the tension of the springs 96.

The upper edge of each rack is provided with teeth for engagement with a corresponding gear 99 in the register mechanism K which includes the supporting levers I for moving the wheels 99 into and out of engagement with the corresponding racks, and a zero stop pawl IOI for limiting the backward movement of the individual gears 99 at a zero position during totalizing. It will be understood also that normal mechanisms for carrying-over or transferring from one gear 99 to the next are employed: such devices are well known in the art and are not here illustrated as details thereof are not a part of the present invention.

The forward end of each of the adding racks 93 includes a structure having a vertical slot I02 for receiving a small roller I03 carried at the rear end of a corresponding angle lever I04 which is mounted by a pivot I05 on a comb block I06 supported at the lower surface of the top plate I4, I5. The forward end of each lever I04 is connected by a roller I01 with the walls of a slot I08 in the rearwardly extending portion of a corresponding adding computation item printing type -bar I09 which has printing types IIO along the upper portion of its rear edge (Fig. 1). These item printing type bars fit closely one against the other (Fig. 2) so that the numerals are printed in close association with one another. Since it is desirable to have the adding racks 93 spaced a greater distance apart for convenience of mechanical assemblage and operation, the rearward arms of the crank levers I04 are successively arched outward (Fig. 2) to afford this clearance of the adding racks 93.

The item-printing type bars I09 have slots III for engaging the rod 84 which thus serves to hold them in alignment and against escape from the groove provided in the shiftable structure by the end walls H2 or a portion thereof (Fig. 2). An error key may be employed for moving the preselector plate 92 backward and accomplishing a clearance of the corresponding pin to eliminate an error in striking a key while setting up for adding. The details of these features are not a part of the present invention. Such a key is disclosedgin Figure 3 of Landsiedel 1,078,358.

The keyboard also includes the keys 20a for the letters. These keys do not have setting levers 59 nor stirrups 55 associated therewith. The spacer bar 20?) operates upon the spacing universal bar 35 during normal typewriting in the usual way.

The keyboard also includes a motor bar MB which upon depression closes a switch SW and thus energizes an impulse-type motor M (Fig. 2) which in association with its clutch system H5 is caused to effect a single revolution of the driven shaft H6 and then bring the shaft to a standstill after a movement of 360 degrees. Such motors and their employment in adding machines are well known (see, for example, the Stickney Patent 1,136,520, Fig. 2, and the Eachel Patent 1,269,797), and their usual connection for effecting a release of the latch means 98, the proper engagement and disengagement of the register K, the return of the preselector pin plate 92, and the clearing of the pins 9I well known in the art and is not illustrated herein.

According to the present invention, this motor has the further function of shifting the ribbon and accomplishing the printing of the item which has been set up by the proper operation of keys 20. For this purpose the shaft I I6 driven by the motor is provided with a disk I" having an eccentric pin H8 thereon. This pin is engaged with .the end of a plunger II9 which extends through a block I20 and through a coil spring I2I and is provided with a nut I22 engaged with its threaded end. The block I20 is fixed at the rear end of the power-shift links I25 which have slots at their forward ends engaged with the pivots I25a (Figs. 1 and 2). The power-shift links I25 include humps I26 which engage rollers riage lug I30 with the stop I3I on the top plate I5 (Fig. 4). Thus, by depressing the tabulating key, the carriage is released and is drawn toward the operators left in the usual way by the carriage spring 40 until the stops are engaged. The specific details of assemblage for this purpose form no part of the present invention: such structures may be found in Figs. 1 and 2 of the Hart Patent 1,270,411.

The keyboard also includesa totals" key operating upon the mechanisms including the register K in known manner for accomplishing the movement of the computation item printing type bars and of the gears 99 for printing the total which has been accumulated in its register K. Equipments of this general type are well known, see for example Siewert 1,957,617.

The operation of the structure is as follows:

Themachine is particularly adapted for employment in preparing lists including typewritten matter and price indications, these price indicaing crank tions' being accumulated on the register and a total printed at the foot of the sheet. In such a case, for illustration, the typewritten matter is contained in columns at the left of the sheet and the price indication in a column at the right of the sheet.

Such a sheet is inserted into the carriage and advanced in the. usual way until a proper line appears at the vision line (just above the rib bon in Fig. 3). The carriage is moved toward the operator's right as usual until it reaches the normal stop for the left-hand margin. The keys of the four row bank and the spacer bar are struck, as with the usual operation of typewriting, so that the proper matter is inserted in the columns for such matter. During this operation of the mechanism, the shiitable structure is at its rearward position as shown in full lines in Fig. 1. The striking of any key of the four row bank depresses the corresponding key lever 2I. The pin 24 thus rocks the correspondlever 25 and causes the corresponding typewriting type bar 20 to fly upwardly and strike the ribbon R and thus produce the corresponding impression. Likewise, each key lever 2I actuates the universal bars 35, 4|, so that the ribbon is raised and the escapement actuated in the normal manner.

with the shiftable structure in its rearward 30 position, i. e., the position for typewriting, the

rods 50 by engagement with the threaded stem 54 of each of the stirrups 50 hold the stirrup in the full line position of Fig. 1, so that no movement is transmitted from the key levers 2I to 86 the setting levers 58.

After completion of the typewriting, the tabulator key 20c is struck so that the carriage is released by rocking of the lever 30 so pawl 01 leaves the ratchet 38 and the carriage is released as in an ordinary typewriter, and is drawn toward he operator's left by the carriage spring. During this movement, the plate 60 presents its inclined surface 60 to the roller 61 so that the shifting lever 88 is rocked in a counterclockwise 46 direction (Fig. 4), thus pulling upward on the link against the action of spring III. The toggle links II and I2 are straightened and a forward push is exerted on pin I5 which is transmitted through the stirrup structure 11 to the 60 rod 04, and thus the shiftable structure is moved forwardly on its ball bearings 6|. It will be noted that the slot in the connecting links I 25 and the slots I08 in the item-printing type bars 7 I09 permit this movement without any interference by these links or by the levers I04. This "forward movement of the shiftable structure I carries the printing'or 'forward ends of the typewriting type bars beneath a fixed stop FS so that they are prevented from upward movement,

and also the pressure along the link 2I'causes a rocking of the crank levers into the dotted line position in which their lower arms are out of normal engagement by the corresponding pin 20 of the corresponding key lever 2|. Thus the 05 typewriting structures are out of action and the item-printing type bars are presented for use.

This shifting forward movement of the shiftable structure also moves the lower extensions SI and 52 forwardly so that the universal bars 20 and II are moved into the dotted line position of Fig. 1 and thus are not encountered by the humps on the key levers 2| when the latter are depressed. These universal bars are illustrated in Fig. 7 as supported in the manner 10 shown by the Smith Patent 1,016,968. Thus the ture has the further consequence of moving the of the stir.- stirrups are rods 53 so that all of the stems 54 rups 05 are moved forwardly and the now presented beneath humps 20b of the corre- I sDOnding key levers 2I (dotted line position, Fig. 1).

The item to. be added is now set up as in a normal ten-key computing machine, by striking the proper keys 20. The downward movement of.

each key lever 2| causes a pull in the corresponding stirrup 50, the length of this pull being ad-. justed by the screw 54 (Fig. 6), so that the corresponding setting lever 56 is proper pin 9| in the first column is set up. The preselector pin plate 92 is then stepped toward the left of the operator in the usual way to present a new column of. pins for the next operation. Thus, the pressing of keys "successively to set up the'ltem to be added results in a corresponding preselection of pins on' 'the preselector pin plate 92in the usual way;

may be cleared by pressing the error keyas 'usual (see Landsiedel 1,078,358).

It will be notedvision point constitutes a common reference for visual determination. of where the typewriting and printing shall; occur.

The impulsemotor-M normally has the fur-.

ther functionof producing the printing sequence. The particular structure for this purpose is incorporated in the present invention and operates as follows: when the motor bar MB is depressed, the latches". are released, and the itemprinting racks and adding type bars move tov In particulanjit jis preferred so to design the proper position. The motor is now energized and its initial clockwise movement causes the eccentric pin H8 to move upward. The upward movement, which continues until the eccentric pin H8 is at topcenter, causes the humps I to actuate the ribbon levers I28 and therewith (see Fig. 3) moves the levers 45 and the ribbon guides 46 and raise the ribbon to a point opposite the vision line, the levers I28 quickly effecting the positioning of the ribbon and then resiliently yielding ior the remainder of the upward movement of the humps 125. The concurrent rearward movement of the pin H8 causes the links I25 to engage the rod 84 and draw the shiftable structure rearwardly so that the selected type or printing element on the item-printing type bars 109 are pressed against the ribbon R and thus print upon the sheet of paper located on the platen P.

Furthermore, the motor M has its usual func tion of releasing the register K so that the gears 99 of this register move into engagement with the racks 93 located therebelow during the printing operation (see the Stickney Patent 1,186,- 520). The further movement of the motor moves the eccentric pin H8 in a forward direction to clear the item-printing type bars I09 from the ribbon so that they may move freely downward. At this time the motor also operates a block Zc which actuates a link Zn. and moves a restoring bar Z (Fig. 8) which presses the racks back to initial position where they engage the latch means 98 and are thus retained. This restoring movement of the racks causes them to energize the corresponding gears 99 of the. reg ister K and set up corresponding amounts on these gears, the usual transfers occurring. At the completion of the restoring movement of the racks 93, the register is again raised out of engagement in the usual way.

Likewise, the release of the item-printing type bars from the ribbon R permits this ribbon and its supporting wires 46 to move downward freely, as the ribbon levers I28 are no longer held upward by the humps I26.

It will be noted that the spring 8| in the toggle system (Fig. 5) permits the rearward movement of the shiitable structure in printing and assists the motor in the forward return movement thereof.

During the printing, the item-printing type bars are presented against the ribbon and are thus pressed against the paper. Various thicknesses of paper and ribbon may be compensated for, and impressions delivered at a desired pressure, by adjusting the nut I22 to determine the strain in the spring 12].

After the item has thus been printed, the carriage can be manually shifted back toward the operators right in the usual way against the action of the carriage spring 40. In this movement, the inclined surface 86 of member 65 releases the roller 61 and the link 10 is drawn downward by the spring 18, thus moving the links H and 13 downward and causing the rearward movement of the shiftable structure back to the full line position of Fig. 1. This movement withdraws the typewriting type bars 28 from beneath the fixed stop FS, restores the universal bars and 4| to positions beneath the humps of the key levers, restores the transfer levers 25 to their full line position ready for actuation by the pins 24, and moves the stirrups 55 out of engagement by the key levers. Thus the adding mechanisms are thrown out of service and the typewriting mechanisms restored for operation. The platen is rotated by any appropriate mechanism, and presents a new line of the sheet of paper at the vision line and the next item is now typed, the price set up, and addition made in the manner described above. This continues as customary until the sheet has been completed.

The total may then be taken. The carriage is moved to proper position and the shiftable structure is brought forward. The totals key and the motor bar MB are pressed. This results, by usual 1 structures, in releasing the register K so that its actuated gears 99 move into engagement with the corresponding racks 93. The latch means 98 is then released so that the springs 96 draw the shown but tha it may be modified in many ways I within the scope of the appended claims.
