The present application is a continuation in part of applicants co-pending application, Serial No. 508,962, filed January 15, 1931. Y
Typewriting machines are known with column computing mechanism arranged on the platen carriage wherein an automatic printing device automatically prints the numerical values upon the sheet of paper on the platen. These known automatic sum printing devices consist of stationary feeler devices arranged in the machine frame, which devices feel the value of the decimal places of the elements set on the numeral wheels in serial order and the individual feeling elements, corresponding to the digits O'to 9, each operate one figure key of the typewriter, so that a key corresponding to a definite numerical value is operated when the feeler element corresponding to this numerical value is actuated. By shifting the platen carriage and the counter, in the printing of the sum total, the individual places of the counter mechanism are successively brought under the feeler devices so that the numerical values contained therein are felt ofi consecutively and printed in proper order.
The sum printing device in accordance with the invention is intended to serve the purpose of transferring automatically, from the stationary counters of calculating machines, the numerical values contained therein to a sheet of paper arranged in a typewriter. Inasmuch as the counters are stationary, in accordance with the invention, the feeler devices corresponding to the figure keys of the typewriter are arranged in a special carriage which is shiftable in the frame of the calculating machine. Upon printing the sum this carriage is shifted by a suitable switching mechanism along the counting mechanism in the direction of decreasing values of the decimal place in such manner that the feeler elements are successively, and in proper order, brought into the positions opposite to all the elements moved by the numeral wheels which are necessary for the feeling operation.
For the feeler elements of the zero key and the spacing key there is provided, in each decimal position of the counter, a zero printing element which is brought into an inoperative position when the element set by the corresponding numeral wheel indicates a numerical value differing from zero and which, on the other hand, actuates the feeler element corresponding to the zero key when the corresponding setting element indicates a zero and a higher setting element indicates a value diiierent from zero, and acts upon the feeler element of the space key when the corresponding and all higher elements move-d by the number rolls indicate a zero.
The sum printing device, in accordance with the invention, is, as already stated, to be used in connection with a typewriter and a calculating machine.
It is to be assumed that the typewriter and the calculating machine are so interconnected that the numeral keys of the typewriter can simultaneously operate the numeral keys of the calculating machine; however, the device connecting the keys of the typewriter and of the calculating machine is not illustrated and described inasmuch as it does not belong to the sum printing device, and, therefore, it does not constitute a part of the invention. 7
In the drawings, the sum printing device, in accordance with the invention, is shown in combination with a typewriter which is connected with a calculating machine.
In said drawings:

Fi 9 is a detail elevation of the return device for t e carriage of the feeler means.
In accordance with Figs. 4 and 5, the typewriter A is connected with the calculating machine B by electrical circuits. These circuitsare opened or clos'edby means of contact devices 23, 24 arranged-inthe calculating machine and controlled in accordance with the setting of the counting mechanism. When these contact devices are closed, electromagnets 25 arranged in the typewriter below the figure keys 26 and below the space key R are energized and the corresponding keys are actuated.
The calculating machine B is made as a 10 key calculating machine with a rack bar drive, wherein the figure values to be entered are set by lifting the setting pins 30 (Fig. 1) of the setting pin carriage 31. In the calculating operation the rack bars 5 are shifted until they abut against the lifted setting pins and thereby drive the figure wheels 2 of the counting mechanism 1 as described in the last four paragraphs of the present specification.
Upon printing the sum, the figure wheels 2 of the counting mechanism are first brought into engagement with the rack bars 5 previously located in' the zero position and are then set to zero, whereby the tens actuating levers 33, held stationary by the flap 32, in combination with the cams 2a, which prepare the tens transfer, determine the zero position of the figure wheels. In the zero setting of the figure wheels the rack bars 5 are brought to a distance out of the zero position, equivalent to that by which the figure wheels are turned back in the zero setting. Over the rack bars 5 each provided with a projection 6, there lie in a carriage 20, shiftable transversely to the rack bars 5, eleven pawls 7, 7b, 70, with bars 22 arranged thereabove. The pawls 7, 7b, 7c, and the bars 22 control the contact devices 23, 24 (Figs. 3, 4 and 5) lying above the same and already previously mentioned, which energize the electromagnets 25 lying below the figure keys and the space key of the typewriter, and thereby move the keys.
That one of the pawls 7, which lies farthest to the right in Fig. 1 operates upon the contact device 23, 24 which is connected with the electromagnet below the figure key 1 the ones lying to the left adjacent thereto act, in order, on the contact devices which are connected with the electromagnets of the figure keys 2 3 etc. up to 9 the pawl 7b acts upon the contact device of the space key and the pawl acts upon the zero key.
Upon printing a sum the carriage 20 with the pawl 7, which previously stands above the highest place of the counter, is moved over the rack bars 5 by a suitable switching mechanism that the pawls 7 with their downwardly directed inclined projections 7a (Fig. 3) first enter above the rack bar 5 corresponding to the highest place of the counter mechanism, and then over the next lower one, etc. to the rack bar with the lowest place value.
If now, for example, the number 674,231 is set up in the counting mechanism, then in the zero position of the counting mechanism that rack bar 5, which corresponds to the highest place of the counting mechanism, is shifted in correspondence with the figure 6 and the adjacent ones which lie to the right are shifted in correspondence with the figures 7, 4, 2, 3, 1 in order, and thereby the projections 6 of the various rack bars are brought into the paths of the various pawls 7 which act upon the contact devices and the electromagnets of the figure keys of the typewriter.
Therefore, at'that instant wherein, due to the shifting of the carriage 20, the pawls 7 with their inclined projections 7a pass above the uppermost rack bar, the pawl 7 corresponding to the figure key 6 of the typewriter strikes the projection 6 of this rack bar, the pawl is, therefore, lifted and by means of the corresponding bar 22 closes the corresponding contact device 23, 24 so that the corresponding magnet 25 is energized and the key with the numerical value 6 in the typewriter is actuated. Then the pawls 7 in succession slip over the adjacent rack bars on the right corresponding to the number 674,231 to be transferred from the counting mechanism and. accordingly the figure keys 6, 7, 4, 2, 3, 1 are actuated.
However, should the number 4000, that is, the
reading 004000, appear in the counting mechanism, then to the left of the digit four there are two zeros which should not be printed while the zeros standing to the right of the digit four must be printed. By a special device the suppression or the printing of these zeros is also accomplished correctly.
For this purpose, a lever 9 is arranged in the calculating machine below. each rack bar 5. All these levers 9 are pivoted about a shaft 10 stationary in the frame of the machine and are held, by springs 11, with their upwardly extending projections 9a against the lower surfaces of the rack bars 5.
To each of these levers 9 there is pivoted an angle lever 13 which is oscillatable about the pin 12. All the angle levers 13 lie with one arm upon a crossbar 17 stationary in the frame of the machine and are held by springs 15 with their other arms against the pins 16 of the levers 9. The upwardly extending arms of the angle levers 13 carry laterally bent tabs 14, projecting forwardly in Fig. 1, and pins 18 projecting rearwardly (Fig. 2). The levers 13 are so arranged with respect to one another, and the tabs 14 and projections 18 are of such dimensions that the projection 18 of each lever 13 lies in front of the tabs 14 of the lever 13 of the next lower place of the machine. If now in the thousands place, corresponding to the number 4000, the rack bar 5 is shifted in accordance with the commercial value 4, when the incline 8 (Fig.1) of this rack bar forces the lever 9 downwardly. Thereby the lever 13 which rests with its horizontal arm upon the cross bar 17 and the upper end of which in Figure 1 projects into the path of motion of the pawl 7b acting upon the space key, is moved downward so that now its upper end lies beyond the path of motion of the pawl '71). Simultaneously the lever 13 is swung to the left in Fig. 1 by means of its arm resting upon the cross bar 17. The levers 13 of the lower places are swung to the left, in a similar manner, due to the projections 18 and tabs 14 whereby their upper ends enter into the path of the zero pawl 70. levers 13 lying above the thousands place, on the other hand, remain in the position shown in Fig. 1 and, therefore, act upon the pawl 7b and the space key. If, therefore, as assumed, the numerical value 004000 is set up in the counter, then when the carriage 20 is shifted in order to print the total, the space key is first actuated twice, then the numeral key 4, and thereupon the zero numeral key three times. The typewriter, therefore, writes 4000 as desired.
The switching mechanism moving the carriage 20 is controlled by the cam 34 of the platen carriage 34a (Fig. 4) of the typewriter. The carriage 34a of the typewriter, upon striking each key, moves to the left a distance equal to the width of a letter or figure. When the ty ewriter carriage 34a .reaches the position at which the cam 34 strikes the counter cam 35, the said cam 35, which is adjustably secured upon a straight edge which is shiftable transversely to its longitudinal axis and is arranged parallel to the direction of movement of the typewriter carriage, is forced back. The straight edge to which the cam 35 is secured is also forced back together with the same, whereby the contact devices 36, 37 and 37, 38 are closed. The electromagnet 38a (Figs. 4 and 6) is energized by the'closing of the contacts 37, 38. Magnet 38a attracts a locking lever 39, This lever normally engages a notch The 20a of the carriage to hold said carriage 20 from movement. When the magnet is energized, the lever 39 is attracted, releasing the carriage 20 and rocking the flap 32 so that it secures the tens controlling lever 33 of the counter, as shown in Figs. 1 and 6a. 9
Almost at the same instant at which the looking lever 39 is actuated, the magnet 40 (Fig. 4) is energized through the. contact device 36, 3'7. The magnet 40 draws the switching bar 41 (Fig. 4) downward, whereby the contact device 43 for feeding current to the motor 42 is closed and simultaneously the clutch 44, arranged between the motor 42 and the gear drive means 45 is engaged for one revolution.
The movement of the motor is transferred through the clutch 44, the drive gearing 45, the shaft 55, the bevel gear 47 and the bevel gear 48 to the cam 49 (Figs. 4 and 8).
The cam 49 operates upon the pin 50 of a push bar 52 guided in a longitudinal hole 51,
said push bar being pivoted at 52a to a bail 54' arranged rotatably about pivot 53. If the cam 49 is at rest, the rack bars 5 and the bail 54 will be held in the position shown. If the cam 49 is set into rotation, the rack bars 5, responding to the pulls of the springs 4, will force the bail 54 (Fig. 8) to the left, so that the pin 50 continuously remains against the cam 49. The cam is so shaped that during the first third of the revolution the bail 54 and the rack bars 5 in Fig. 8 move to the left, until the locked tens setting levers 33 (Fig. 6) in cooperation-with the tens setting projections of the'figure wheels prevent a further shifting, during the second third of the revolution a resting of the rack bars 5 in the new position takes place, and in the remaining third the push bar 52, in combination with bail 54 and the rack bars 5, are again brought back to the initial position.
By the closing of the contacts 37 and 38 by means of the cam 34 secured to the platen carriageand the'counter cam 35, current will be carried not only to the electromagnet-38a but also the electromagnets 73a and 73b (Figures 4a and 6a) which are provided on lugs 72a and 72b of magnetic material, provided on both sides of the numeral mechanism 1. According to this structure the electromagnets 73a and 731) will pull the numeral mechanism downwards out of engagement with the racks 5 against the action of a spring, not shown, whereby the toothed wheels of the numeral rollers of the numeral mechanism will engage with the rack bars 5.
The cam 34 which is provided on the typewriter carriage as well as the counter cam 35 is so dimensioned that at the instant the contact of the cams is broken the magnets 72a. and 73b will be de-energized so that the numeral mechanism 1 will be disengaged from the toothed bars 5 by means of springs.
Uponthe extension of the shaft 55 which carries the bevel gear 47, there is a further cam 56 which has the purpose of producing the movements of the carriage, which is under the influence of the springs 61, (Figs. '7 and 9), by
means of the lever 57, at the desired times. Thelever 5''! has its fulcrum at 58 and lies with the pin 59 against the cam 56 while its fork-like end 570. surrounds a lateral projection 60 of the carriage 20.
Upon rotation of the shaft 55 the cam 56-moves in the direction of the arrow (Fig. 9) from the position shown. The shape ,of the cam is so chosen that in the first third of the revolution the lever 57 and with it the carriage 20 remain in the position illustrated. Beginning at the second third the carriage 20 can move in the direction of the acting force of springs 61 to a position determined by the shape of the cam, while in the last third of the cam revolution the lever 57 and thereby the carriage 20 are positively returned into the initial position.
When the carriage 20 has returned to the initial position, the locking lever 39 will fall into the locking, hook 62 of the carriage '20, whereby the previously existing locking position is again restored. v
The two cams 49 and 56 accordingly operate in dependence on one another, in such manner that, as already stated, inthe first third of a revolution of the shaft 55, the rack bars 5 can become set, while the pawl carriage 20 still remains in the position of rest. In the second third In order to be able to make the switching arplaten carriage 340., a second cam 35a (Fig. 4)
is used, which is so shaped that it is forced back by the cam 34 of the typewriter carriage 34a. only as far as is necessary to close the contacts 36, 37. The contacts 3'7, 38, therefore, are not closed by this second counter-cam. Conseouently, only the magnet 40 is energized, so that also solely the switching bar 41 is moved. The motor is thus provided with current and the cams 49, 56 are turned, while, on the contrary, the locking lever 39 which secures the carriage 20 is not disengaged, because the magnet 38 is not energized. The feeler device, therefore, is not set into action and an automatic printing of the sum does not take place.
A contact device 66, 6'7 which is moved by the carriage 20 through the bar 65, prevents a secriage 20 into the position of rest, therefore, no
current closures are produced, even though the pawls '7 are lifted from the projections 6 and the contacts 23, 24 are closed. I
Shortly before the carriage 20 again reaches jection 65a. of the bar 65; this is carried along and again closes the previously opened contacts 66, 67 so that upon renewed moving of the pawl carriage 20 the sum printing device again becomes operative.
the initial position, its offset 69 meets the pro- The bar 65 is shiftable, by means of longitudinal holes 71, on stationary pins '70 in the frame of the machine and is held by the pawl 68 in one or the other end position.
As already stated hereinbefore, the rack bars 15( 5 then the contact device 36, 37 is closed, but not the contact device 37', 38. Therefore, the motor 42 is connected in circuit, but the carriage 28 of the total printing device remains locked, so that-no printing of the total'takes place. The motor 42 turns the cam disc 49. During the first third of each rotation of the cam disc 49 the rack bars 5 (by virtue of the springs 4) follow the .bail 54, until the ends of the rack bars strike against the setting pins which have been raised in correspondence with the present number. In the second third of the rotation, during which the.
- rack bars 5 meat rest. the register mechanism is then brought into engagement with the rack bars. bars 5 are returned to the initial position, whereby the flgure wheels 2 brought into mesh therewith are turned in correspondence with the preset number. As soon as the rack bars have reached the initial position the register mechanism is disengaged therefrom.
The meshing and non-meshing of the numeral mechanism 1 with the rack .bars 5 is carried out during the calculations by acam 49 (Figure 8) mounted on the shaft, that is, by the camdisc 80 (Figure 4a) of the cam 49 with the raised sur-- face 80a which constitute approximately onethird ofthe circumference of the cam disc. The
surface 80a is adapted to operate two contact tive. When the machine is standing still the cam disc 80a is in the position shown in Figure 4a and this disc rotates during the operation of the machine in the di'rectionof the arrow. The cam surface 80a, therefore, closes the contact arrange-. ment 82 during the last third of a period of complete revolution of the cam disc'80 and the cam 49. The magnets 72a and 12b are, therefore,
- energized during every last third revolution of the 7 whereas in the second case they-willbesubtracted.
If a plurality of rotations be imparted to the cam disc 49, then the number pre-set into the setting pins 30 will be transferred a plurality of times into the register mechanism, as is necessary in multiplications. -The setting pin carriage 31 may be shifted by striking the zero key. Therefore, the number pre-set into the setting pins may be transferred to any desired places of the register mechanism by shifting the setting pin carria e.
The above described rack bar drive docs not constitute a part of the invention. This drive mechanism is described here solely to show how In the last third of the rotation the rackthe device, in accordance with the invention. cooperates with the remaining parts of the calculatving machine.
It is immaterial, as far as the invention is coneerned, whether the elements'of the total printing device which are pre-set by the figure wheels are formed as rack bars or as gear segments or as any other settable elements; it is also not necessary that the elements of the total printing mechanism which 'are set by the figure wheels should simultaneously form a portion of the register drive means. The construction of the register drive means is immaterial as far as the invention is concerned.
