(01. 235-59) The invention relates to a printing adding machine, with column counters arranged on the paper carriage.
Printing adding machines have been provided;-
with column counters, which are arranged on the paper carriage, in order that these machines can execute column work as this can be performed in typewriting calculating machines: The advantage of typing text however, is lost in such machines. The typing of text is particularly indispensable in pay and invoice matters.
This disadvantage is obviated according to the invention in which the printing adding machirie is combined with a typewriting machine, both machines being advantageously arranged side by side.
Accordingto a preferred form, both machines are provided with a common paper carriage, .which carries the column counters.
In the drawings one example of the invention is represented.

General description The typewriting machine, 2, is arranged at the right hand, and the adding machine, 3. at the left hand of a common base plate I (Fig. 1).
The typewriting machine, 2, is provided with the usual letter typing keys, 4, and figure typing keys, 5, which letter and figure typing keys are connected in a known manner with the type levers, '6, (Fig. 2). Underneath and in front of the letter keys, 4, are arranged In calculating keys, 1.
with the numbers 0 to 9 for the adding machine,
3. The levers, 8, of the calculating keys, I, (Fig. 3) at their rear ends are mounted on bearings at, 9, so as to be capable of oscillation, and by means of a. pin and slot connection, I 0, ll, they are connected to setting levers, ii, for the stop carriage, l5, of the adding machine, 3. The levers project towards the left and are pivotably mounted in bearings on bearing blocks, [3, (of any suitable type) attached to the machine frame in any suitable manner. If a calculating key,1, is depressed, the lever, i4, connected with the key lever, 8, is swung in the clockwise direction and by means of the upwardly projecting rear end. 16, of the same, the corresponding stop, I1, is set in the stop carriage, i5, and is held by means of aspring, l8, in this working position. The stop carriage, i5, as is evident in Figs. 2 and 3, is slidably arranged, by means of rollers, IS, on two rails, 20 and 2i, fixed in the machine, and for the remainder is arranged similarly to the stop carriage represented and described in Patent Specification No. 1,329,028.
. Against the stops, ll, set as above described the feeler rods, 23, (Fig. 3) are released on the operation of the machine by means of a crank handle (not shown) or through the depression of a motor key, 22, (Figs. 1 and 2), whereby under the action of the springs, 25, acting n the type printing rods, 24, and through the pin and slot connections, 26, 21, and the sectors 29, carrying the toothed segments, 28, 28a and 28b, and the pin and slot connection, 30, 3i, the feeler projections, 32, of the feeler rods are carried against the set stops, i1, whereby the driving sectors, 29, and the toothed segments, 28, 22a.
and 28b, rotatably mounted on it, are YOliflifid duce this value into the totalizers. By means of the slots, 23a and-23b, in the feeler rods, 23,
into which project suitable screws, 23c and 23d,-
arranged in any suitable manner on the machine frame, the feeler rods aredisplaceable in the direction of the arrow 1.
As soon as the type-printing rods 24 have been raised by theirsprings 25 in accordance with the amount set up by means of the calculating keys I, the hammer mechanism-which will be described later on in a more detailed manner-is operated to thrust the types against the platen 33 which is common to the adding machine 3 as well as the typewriting machine 2.
Pin carriage escapement In the operation of one of 'the calculating keys, 1, the rearwardly directed part of the lever, l4, (Figs.3 and 13) acts with its upwardly directed edge, l4a,'on a yoke, 20x, swingably mounted at the points, 200. and Mo, on the running rails, 20 and 2|. The yoke, 20:, at the part, 20c, connecting the limbs, 20b and. Zlb, is downwardly angled and is provided with teeth, 20d, between which the rearwardly directed levers, H, which at their free ends are bent towards A the left, (Fig. 2), are capable of projecting and in this way are .simultaneously .guided. yoke, 20x, now,.on the striking of one of the calculating keys, I, can act in any suitable manner on the nose'20F of the part 20G of the shift lock 20A, (Figs. 3,8, 9, and 13), for instance through the intermediary of a lever 20b fixed to the limb 20b of the yoke Mar, and effect a step movement of the stop carriage to the left (Fig. 2), which process will not be further described here, as this is generally known. In the following, solely for the sake of completeness, the shift lock, 20A, will be described.
By means of the screws, 20B, (Figs. 3, 8 and 9) a plate, 200, is secured to the machine frame, which is rearwardly bent at its free end, and is provided with two lateral downwardly projecting U-shaped limbs, 20D. In threaded holes, not shown, provided in the limbs, 20D, screws, 20E, are inserted, around the points of which the part, 20G, carrying the fixed shift-tooth, 20F, is swingably mounted by means of its upwardly bent lugs, 20H. The spring, 20y, which at one of its ends is connected to the part, 2llI,
of thepart, 20G, and at its other end is conneoted to the part, 20C, acts on the part, 20G, in the anticlockwise direction around the screws, 20E, (Fig. 9), whereby the part, 20G, presses upwards against the screw, 20K, of the part, 20C, and the normal position of the part, 20G, is thereby determined. The projection, 20L, of the part, 20G, is constructed like a tooth, and this tooth, 20F, coacts with the teeth, 20M, (Fig. 8) of the rack, 20N, fixed to the stop carriage, 15. By means of the screw, 2UP, a lever, 20Q, is swingably mounted on the part, 20G. The pin, 20R, (Fig. 8) provided on the part, 20G, projects through an elongated hole, 208, of the lever, HQ. The spring, 20V, which is connected to the pin, 20T, of the part, 20G, and to the pin, 20a, of the lever, ZUQ, acts on the lever, 2DQ, round its axis, 2UP, in the anticlockwise direction, so that the lcver,-20Q, rests with its face, 20W, formed by one end of the elongated hole, 208, against the pin, 20R, provided on the part, 20G, whereby the normal position of the lever, 20Q, is determined; On
The
the lever, HQ, 8. lug, 202, is upwardly bent, which lug co-acts with a lever to be later described.
At the point, 209, a two-armed lever, Mn, is jointed to the part, 206), to a limb of which a spring, 20k, is attached, which, with its other end is connected to the lever, ZOQ, and acts upon the two-armed lever, 20h, in the clockwise direction. The forwardly directed limb of this lever is provided with a projection, 20m, (Fig. 8), with which it can co-act with the projection, 202, of the lever, ZOQ. The rearwardly projecting tooth-like end, 20:), of the lever, 20h, is in engagement with the teeth, 20M, of the rack, ZUN, of the stop carriage, l5, and as the stop carriage, I5, is acted upon in the direction of the arrow, M, indicated in Fig. 8, by a spring, which is not represented, the lever, 20h, rests with its projection, 201, against a lug, ZUQa, bent on the lever, 20Q, whereby the lever, ZDQ, is again acted upon round the axis, 2UP, in the anti-clockwise direction and rests with the face, 20W, of its elongated hole, 208, against the pin, 20R. whereby the normal position of the parts, 20Q, 20h, is determined.
follows:
On depression of a key I, the rear end 16 '(Figs. 3 and 13) of its key lever l4 sets a stop in the stop carriage l5. At the same time the yoke 20:: (Fig. 13) is rocked upwards round its screws 20a and 2|a., Thereby, the lever 20b, fixed to the yoke 20x raises the part 20G, which is rocked clockwise (viewed in Fig. 9) round the screws 20E against the action of the spring 201 As a result, the loose dog 20p, 20h disengages the teeth 20M of the rack 20N of the stop carriage whereas the oblique face of the fixed dog 20F engages the same as shown in Fig. 8a. Consequently, the loose dog 20p, 2011 is rocked clockwise (Fig. 8) by means of its spring 20k, which movement is arrested by the lug 202 of the part ZDQ. As a result, the tooth 20 of the loose dog is now just over the next tooth space of the rack 20N. As soon as the depressed key I is released, the spring 20y (Fig. 9) restores the part 20G to its rest position. Thereby the fixed dog 20F releases the rack ZON and the tooth 20p of the loose dog enters the tooth space, lying opposite to it. By means of the stop carriage spring (not shown), the stop carriageis urged in the direction M (Fig. 8) until the loose dog 20p, 20h impinges with its part 201' against the lug ZOQa. Thus the stop carriage is displaced one step in the direction of the arrow M (Fig. 8).
v In the return of the stop carriage, 15, into its initial position as represented in Fig. 2, the teeth, 20p, of the lever, 20h, slip over the teeth, 20M, of the rack, 20N, of the stop carriage, l5, whereby the lever, 2071., is swung round the point, 20g, in the clockwise direction, which takes place quite freely, as in this swinging movement of the lever, 2071, the lever, ZUQ, is also swung against the action of the spring, 20V, round the point, 20?, in consequence of the action of the projection, 20m, of the lever, 20h, on the lug, 202, of the lever, ZIJQ.
Printing mechanism the two printing mechanism frame walls arranged in the machine, of which in Fig. 4, however, only the right one is visible.
Between the two printing mechanism frame walls,
The operation of the escapement is briefly as 34, a part, 36, of angular formationv having both of its free ends bent rearwardly at right angles is secured by means of the screws, 35, Fig. 4, to the right-hand printing mechanism frame wall, 34,
and is fastened bymeansof screws not shown to a the left-hand printing mechanism frame wall, 34. This part, 36, is provided with as many slots, not shown, as there are printing rods 24. 1
The printing mechanism frame here illustrated is arranged by way of example for ten denominational orders. The slots serve as guides for type printing rods, 24, to be later described in a more detailed manner. The type printing rods are so arranged that the distance between printed figures in adjacent orders is equal to thedistance of the letters of the typed text. The angle-shaped part, 36, is still further provided with ten holes not shown, from which are hung the springs, 25, (Fig. 4), which at their other ends are connected to the noses, 31, of the type printing ,rods, 24, and act upon these rods in the direction of the arrow, D. By means of screws, 38, (Figs. 3 and 4) a part, 39, of angular formation and with its free ends bent forwardly at right angles, is further fixed to the right printing mechanism frame wall, 34, and to the left printing mechanism frame wall, 34, by means of screws not shown. The part, 39, similarly to the part, 36, is provided with ten s1ots,'not shown, which likewise serve as guides for the type printing rods, 24.
Further, in the zone of the lower ends of the type printing rods, 24, and between the two printing mechanism frame walls, 34, (Figs. 3 and 4) a part, 40, of U-shape having both its free ends bent upwards at right angles, is arranged. This is,
fastened to the right-hand printing mechanism frame'wall, 34, by means of screws, 42, (Figs. 3 and 4) passing through its bent lug, 41, and' to 40 the left-hand printing mechanism frame wall, 34,
which is not shown. The part, 48, is provided with ten slots, not shown, which serve as guides for the type printing rods,'24. The parts, 36, 39, 40 and 34, form the printing mechanism frame proper.
On the upper ends of the type printing rods, 24, lugs, 43, (Fig. 4) are bent, so that a number of rectangular shaped recesses are formed, in which number types, 44, are slidably arranged. In Fig. 4, the cover plateis omitted in order to render the number types, 44, visible. The number types, 44, which on their rearwardly directed ends, carry the types, 45, are provided with projections, 46 and 41,
.(Fig. 4). By means .of compression springs, 48,
which on one side rest against the left-hand lugs,
43, of the type printing rods, 24, and on the other side rest against the faces of the projections, 46, of the number types, 44, the number types, 44, are held in their rest position, which is determined by the contact of the right-hand faces, 46a, of,. the number types, 44, against the right-hand lugs,
-43, of the type. printing rods, 24.-
On the noses, 49, of the type printing rods, 24, as already described, pins, 26, (Figs. 3 and 4) are riveted, which are embraced by fork-shaped arms,
50, of the driving sectors, 29, swingable around the shaft, 51.
Difleremiial mechanism 4 The driving sectors, 29, under the pull of the 'springs, 25, attached to the type printing rods, 24,
'rest with their parts, 52, against a bar, 53, (Fig. 4), which at its free erids is fixed to the angle lever; 54, (in Figs. 3 and 4 only the right hand angle lever is visible). These two angle'levers which are arranged to the right and left of the driving sectors, 29, are swingably mounted on the shaft, 51. By means of springs, 55, which on the one side are connected to the angle levers, 54, and on the other side to pins, 55a, provided on the machine frame, the levers, 54, are acted upon in the clockwise direction. These and the bar, 53,- also form a yoke. On eachof the downwardly directed ends of the angle levers, 54, a roller, 56, is provided (in Fig. 4 only the righthand roller is visible), each of which rests against a cam, 58, fixed on a shaft, 51, (in Figs. 3.and 4 only the right-hand cam is represented). By the action of the springs, 25, which on the oneside are attached to the nose, 31, of the type printing rods, 24, and on the other side to the angle shaped part, 36, as already earlier mentioned, the type printing rods, 24, are acted upon in the direction of the arrow, D, and likewise the parts, 58 and 29. By the contact of the parts, 52, of the driving sectors, 29, with the bar, 53, and the contact of the roller, 56, of the angle lever, 54, with the cam, 58, the normal position of the parts, 24, 5 8, 29, 53, and 23, is determined.
,The driving sectors, 29, (Figs. 3 and 4) are provided with lugs, 59, which co-act with projections, 68, of the three tooth segments, 28, 28a, and 28b,
which are swingably mounted at the points, 61, on the driving sectors, 29.. By means of the springs, 62, which on one side are connected to a lever arm, 63, Fig. 5 of each of the toothed segments, 28, 28a, and 28b, and on the other side to the lugs, 64, of the driving sectors, 29, normally the toothedfsegments, 28, 28a, and 28b, are held with their projections, 60, in contact with the lugs, 59, of the driving sectors, provided that the driving sectors 29 are rotated in the opposite direction of the arrow 0. If however, the driving sectors 28 are in their rest position as represented in Fig. 5, the tooth segments 28, 28a and 28b are held against the action of their springs 62 by means of their tens transferlevers 88, 61, 68.
Tens transfer structed as in Fig. 5, are swingably mounted. On
each of the limbs, 61a and 68a, two noses, 69 and 10, are provided, which co-act with the tens. earns, 15, on the toothed Wheels, 1| and 12, of the one totalizer and with the tens cams, 15, on the'toothed wheels, 13 and 14, of the other totalizer.
Further, on the shafts, 16and 11, fixed in the machine frame, pawls, 18 and 19, formed as in Fig. 5, are swingably mounted, which can co-act .with the small levers, 61 and 68. By means of the springs, 83 and 84, which on the one side are connected to the noses, 80, of the small ,levers, 61 and 68, and on the other sideto the noses, 8|, of the pawls, 18 and 19, the pawls, 18 and 19, are held with the levers, 61 and 68, in the normal position as represented in Fig. 5.
The pawis, 86, which are swingably'mounted on the shaft, 85, and co-act with the angle levers, 88, swingably mounted on the shaft, 81, are held in their rest position as represented in Fig. 5, by the springs, 89. The upwardly directed limb, 88a, of the two-armed lever 88, co-acts with a lever, not shown, which is swingably mounted in the column counter, V, which lever in the patent application Serial No. 555,331 is indicated by, 80, and is exhaustively described, and which can co-act with the tens shift cam indicated there by, 81.
It may be remarked that the lever, 61 or B8, belonging to number wheels, 93, disposed farthest to the right of the cross totalizer, Q, and, 99, of the cross totalizer, QI, are bent so far to the left that the same are able to co-act with the pawls, 18 or 19, following on the left, and so forth which on the following grounds must be the case. If for example the value v8 is registered in the number wheel, 93, farthest to the right of the cross totalizer, Q, and if the value 4 is to be added, in order to obtain a correct result, a tens transfer must take place, which is effected as follows: In the instant in which the number wheel, 93, farthest to the right rotates from 9 to 0, the cam 15, of the toothed wheel, ll, of the cross totalizer, Q, acts on the nose, 99, of the lever, 61, and swings it against the action of the spring, 83, round its axis, 65, in the clockwise direction, out of the position represented in Fig. 5, whereby the pawl, 18, following on the left which lies in one plane with the second number wheel, 93, from the right, is swung under the pull of the spring, 83, so that the nose, 7871, of the pawl, 18, springs into the step, 611', of the lever, 67, and holds this in position, so that in the swinging of the corresponding toothed segment, 28a, this does not push with its part, 28x, against the nose, 83p, and in this manner a further swinging movement of the toothed segment 28a of one unit in anti-clockwise direction will be released. In the swinging of the driving sectors, 29, and of the toothed segments, 28a, the toothed segment which cannot be held by the pawl, 73, further rotates the toothed wheel, ll, of the second place from the right of the cross totalizer, Q, through one division, so that the number wheel, 93, is rotated from 0 to l, and a tens transfer has thus taken place. termination of this process, the roller l3! drops into the lower part Hill of the cam ISIA under the action of the spring I40, acting on the arm H3211, whereby the arms I321), I320, l32cl are swung in the anti-clockwise direction around the shaft 5i. With this, the part, I35, of the arm, 21320, of the lever, I32, acts on the nose, 136, of the pawl, 79, and swings this in the clockwise direction, whereby the nose, 1811, moves out of the step, 67, of the lever, 61, so that the lever, 61, under the pull of the spring, 83, can again return into its rest position represented in Fig. 5. However, the lever 61 does not immediately return to its rest position, but rests with its nose 833) on the nose 281' of the segment 28a. After the releasing movement of the lever 61 by the pawl 18 has taken place, the raised part |39h of the cam l3lA acts on the roller I3 I whereby the arms I321), I320 and |32d are rotated in clockwise direction. During this rotation the segment 28a is returned to its rest position, in which the nose 83p of the lever 61 falls behind the nose 281' of segment 2812, holding it thus in its normal position, as illustrated in Fig. 5.
Totalizer operation The teeth 92 of the toothed segments 28 engage the toothed wheels designated at 9lh in the accompanying drawings as well as in the former U. S. application Sr. No. 555,331, whereby in the swinging of the toothed segments 28 the value is registered in the column counters V in the additive or subtractive sense.
The toothed segments 28a may engage with the toothed wheels "II or 12 according to whether the cross totalizer Q is set for addition or for sub- On the traction. If the toothed wheels, H, are in engagement with the teeth of the toothed segments, 28a, in the operation of the machine, the toothed wheels, H, are acted upon by the tootl' ed segments, 28a, in the direction of the arrow, a, and the number wheels, 93, rotated in the positive sense through the toothed wheels, 12 and 94, and 94a. If, on the contrary, the toothed wheels, 72, are in engagement with the teeth of the toothed segments, 28a, the number wheels, 93, are acted upon through the toothed wheels, 94 and 94a, in the negative sense, therefore opposite to the direction of the arrow, 1), indicated in Fig. 5.
Totalizer shifting To the left of the cross totalizer, Q, which is slidably arranged on the shaft, 99, fixed in the right-hand side wall, 95, of the machine frame, (Fig. l) a sleeve, 96?), provided with a ring groove, 96a, is arranged, into which ring groove, 95a, projects the fork shaped end of a slide, 9'1, displaceably arranged on the front wall of the machine. The slide, 97, is provided with a knob, 98, by means of which the displacement of the cross totalizer, Q, to the right or to the left, on the shaft, 96, can be effected.
If the cross totalizer, Q], is to operate in the positive sense the rotational direction corresponding to which is indicated by the arrow, the toothed wheels, 73, will engage with the teeth of the toothed segments, 28b, and if the cross totalizer, Qi, is to operate in the negative sense the toothed wheels, 14, will engage with the toothed segments, 28?).
In order to effect a displacement of the totalizer, Qi, to the right, a sleeve, not shown, having a ring groove, is provided on the left of the lefthand side wall, I90, (Fig. 3) of the totalizer, Ql, which sleeve likewise is displaceable with the cross totalizer, Qi, on the shaft, 19h. With the ring groove of the sleeve, the fork-shaped end of a slide, H12, engages which is displaceable in the front wall of the machine and its end which projects from the front wall of the machine is provided with a knob, I03, by means of which a displacement by hand of the cross 'totalizer, Ql, is rendered possible to the right or to the left. The cross totalizers, Q and Ql, which are mounted on bearings on the adding machine, are displaceably arranged in order to enable multiplication to be performed by them in a. simple manner.
Cam arrangement for "totalizer engagement. control For controlling the engagement of the totalizers Q and Q! with their actuating racks, the following arrangement is provided. On the shaft 51' two sleeves I28 and 57a are slidably but nonrotatably mounted. On each of the sleeves I28 and 57a there are fixed three cams. The cams H to H3 are provided for the totalizer Ql and I the cams Illa to 113a for the totalizer Q. The
4x, the sleeve I28 is provided with a knob- I90.
, Furthermore, a pointer I29 is rotatable on the sleeve I28 but so mounted as to be axially displaceable therewith. The pointer I29 is. held against rotation by its embracing the part I29a displaying the different positions D (neutral) T (Total) ST (subtotal) 'of the cam seriesinwhich positions the sleeve I28 may be held by any suitable means.
The cam series IIIa to 9a is displaced by the following means. The sleeve 51a. having a ring groove 51b engaged by pins 510 fixed on a vertical arm of an angle lever 51d slidably mounted on the frame. The end of the horizontal arm of the angle lever 51d projecting from the left hand side wall of the machine is provided with a handle 51c and a pointer 51 coacting with the marks D, F, St (Fig. 1) for the pointer I29. Similar means as for the sleeve I28 are provided for the angle lever 51d for holding it in the diiierent positions of adjustment.
Totalizer engagement control this case, the pointer51f has to be set to d."
, Furthermore the lever, I04, by means of the knob,
I04a, (Figs. 1 and 3) is moved from the neutral, (D), to addition, (A), whereby the same is acted upon in the clockwise direction, round its axis I05, and the connecting rod, I06, jointed to its rearwardly directed free limb, I05a, is moved in the direction of the arrow, 0. The rod I06 then swings the lever, I01, around its axis, I08, in the anti-clockwise direction, whereby the pin, I09, provided on the side wall, 952:, of the totalizer, Q is embraced by the recess, IIII, of the lever, I01. The swinging of the lever I01 about the axis I08 is possible because the guide slot of the angle shaped guiding bracket shown above the connecting point of I06 and I01, is wide enough in order to permit such swinging movement of the lever I01. If now the hand crank or the motor key, 22, is operated, the driving shaft, 51, is retated in the direction of the arrow, d, so that the cam II3u. can act on the angle lever II4 thereby controlling the totalizer Q for addition, that is to say the totalizer Q is rocked round the shaft 96 in the anti-clockwise direction, whereby the toothed wheels 1I engage with the toothed segments 29a on their return movement.
If on the contrary, a value is to be registered in the totalizer, Q, in the negative sense, it is only necessary to set the lever, I04, at subtraction, whereby the lever, I04, is swung in the anti-' clockwise direction and the connecting rod I06, correspondingly moved in theopposite direction to that of the arrow c. The lever, I01, is thereby acted upon in the clockwise direction around the point, I08, whereby the pin, II5, provided on the side wall, 95. of the totalizer, Q, is embraced. by the recess, II6, of the lever, I01. If now the lever, I01, in consequence of the rotation of the shaft 51 by the cam II3a through the lever H4 is acted upon in the direction of the arrow 6 the toothed wheels 12 of the totalizer Q engage the toothed segments 28a on'their return movement, rotating thereby the number wheels 93 in the negative sense.
I! the lever, I04, is at neutral, D, the parts, I04, I06, and I01, assume the position represented in Fig. 3, whereby on the operation of the hand crank or of the motor key, 22, the lever, I01,
' through the parts, 51 and I I3a, as well as throughthe lever, H4, is operated inthedirection 0! the arrow e, but slides however, inoperative past the pins, I09, and I I5, of the totalizer, Q, so that this is not displaced and no amount can be introduced into the same. By means of a locking pawl, 94A, (Figs. 6 and 7) which is rotatably mounted at the points, 943, on the two side walls or the totalizer, Q, (in Fig. 6 only the left-hand axis is visible) in the'rest position (represented in full lines in Figs. 6 and '1) the toothed wheels arranged in totalizer, Q, as'well as the number wheels, 93, are locked, i. e. an unintentional rotation is thus avoided. In the swinging into the addition position (represented in- Fig. 6 in dotted lines) the projection, 94D, of the locking pawl, 94A, pushes against -a pin, 94C, fixed in the machine frame, whereby the locking pawl, 94A, 'moves out of engagement with the teeth of the toothed wheels, 94, whilst the toothed wheels, 1 I, simultaneously engage-with the teeth of the toothed segments, 28a. The process in the swing-' ing of the totalizer, Q, into the subtraction position is similar. In this, however, the swinging of the locking pawl, 94A, is effected through striking of the projection, 94D, or the locking pawl 94A, against the pin, 94H, (Fig. '1) fixed in the machine frame.
The swinging of the. totalizer, QI, for the purpose of introducing a value in the positive or.
negative sense is efiected by the knob, I I9, of the lever, I20. If the same is set at addition, A, therefore acted upon round its axis, I2I, in the clockwise direction so the connecting rod, I23, jointed on one side to the lever, I20, and on the other side to the lever, I22, swings the lever, I 22, in the anticlockwise direction, whereby the recess, I24, of the lever, I22, embraces the pin, I25, which is provided on the left-hand side wall, I00, of the totalizer QI. v subtraction the cam II3 cooperates with the lever I I43 and if now the hand crank or the motor key 22 is operated, the lever I22 is moved in the direction ,of the arrow f whereby the totalizer, QI, is swung roundthe shaft, IOI, in the anticlockwise direction and thus the toothed wheels, 13, of the totalizer, QI, are brought into engagement with the teeth of the toothed segments, 28b,
As in the case of addition and and in the swinging of the toothed segments 28b,
the number wheels, 99, are actuated in the positive sense. As the introduction of a value in the negative sense into the totalizer, QI, is obvious from the above description, it will not be here gone into further. It may be still remarked that in order to be able to displace the totalizer, QI, to the right, between thetoothed wheels disposedon the left-hand side and the left-hand wall of the totalizer, distance pieces 95!; (Fig. 14) are arranged. Besides the right-hand side wall, 95a, of the totalizer, Q, and the right-hand side wall, I00a, of the totalizer, QI, as is evident from Figs.
6, '7 and 3, are formed so small that on a displace-,
, levers, I01 and I22. The setting of the totalizers,
Q and QI, on neutral, total and sub-total is obtained as follows:
On this sleeve 3 cams, III, H2, and H3, are fixed. Furthermore, a pointer I29 is rotatably mounted on the sleeve I28 but so as to be axially displaceable therewith. If the pointer, I29, which is held against rotation by its embracing the part I29a. as shown, points at neutral, D, in which position the lever, I I410, is disposed over the cam, II3, the cam, II3, acts on the lever, 41:, in the second half of the revolution of the shaft, 51, whereby the same acts upon the lever I22 in the direction of the arrow f. As a result the toothed wheels 13 or the toothed wheels 14 are brought into engagement with the toothed segments 28b at the beginning of their return movement in the direction of the arrow 9 according to whether the totalizer QI has been set by means of the knob I I9 to addition or to subtraction. As soon as the wheels 13 or 14 have engaged the segments 2812, they transfer the amount into the totalizer QI additively or subtractively.
If by means of the knob I30, the pointer I29 is set for total T, the cam H2 is brought into the operative position in relation to. the lever 4.1:. As a result, according to whether the knob I I9 has been set to addition or to subtractionthe wheels 13 or 14 are engaged with the toothed segments 28b immediately on the operation of the. hand crank or motor key 22, that is to say, prior to the excursion of the segments 28b in the opposite direction of the arrow 9. Consequently, the amount displayed by the number wheels 99, is withdrawn and the number wheels remain at zero, because the shape of the cam I I2 is such that the wheels 13 or 14 are disengaged with the segments 28b as soon as they have completed their excursion in the opposite direction of the arrow 9 whereupon they return idly to their rest position.
If now the pointer I29 by means of the knob I30 is set for subtotal ST, the cam II comes into the working position in relation to the lever I I43. As a result, according to whether the knob I I9 has been set to addition or to subtraction, the
wheels 13 or 14 are engaged with the toothed segments 28b also immediately on the operation of the hand crank or motor key 22, just as is the case in total taking. However, the shape of thecam I I I is such that the wheels 13 or 14 remain in engagement with the segment 281) both in their excursion in the opposite direction and in the direction of the arrow 0. Consequently, the amount displayed by the number wheels 99 is left on the same as is usual in subtotal taking.
For controlling the totalizer Q of the neutral other is provided with a sleeve 51a. having a ring cross 51b engaged by bolts 51c fixed on a vertical arm of an angle lever 51d slidably inmmted on the frame. The end of the horizontal arm of the angle lever 51d projecting from the lefthand side wall of the machine is provided with a handle 51c, and a pointer 51! coacting with the marks D, T, St (Fig. 10), for the pointer I29.
a4, a shaft, m, (Fig. 4) is' fixed so as to be incapable of rotation. On this shaft, I44, angle levers, I45, alternately with a distance ring, not shown, are rotatably mounted. In the machine being described by way of example, ten angle levers, I45, are arranged.
on the downwardly projecting limb, I46, (Fig. 12) of each of the angle levers, I45, on each side of the same, a further lever, I41, is jointed. Of the levers, I41, only the left-hand one is visible in Fig. 4. The ,levers, I41, are rigidly connected to one another by means of pins, I48 and I49, which project through elongated holes, I50, I5I, in vertically slidable arranged slides, I52. On the left hand levers, I41, noses, I53, are formed, which are so bent that they lie in the plane of the slides, I52. To the noses, I53, springs, I54, are connected, which at their other end are attached to noses, I55, of the slides, I52. The springs, I54, act upon the levers, I41, and the slides, I52, in such relation to one another, that the faces, I56, and I51, of the elongated holes, I50 and I5I, of the slides, I52, rest against the pins, I48 and I49, fastened to the levers, I41, whereby the normal position of the slides, I52, in relation to the levers, I41, is determined. Springs, I58, which are connected on the one side to the noses, I59, of the slides, I52, and on the other side to an angle shaped part, I60, act upon the slides, I52, together with the levers, I41, in anti-clockwise direction, and in the direction of the arrow D. The angle-shaped part, I60, is fixed by means of screws, I62, which pass through the rectangular downwardly bent lugs, I6I, (in Fig. 4 only the right hand lug is visible) formed on its free ends to the two parts of the printing mechanism frame walls, 34. Through the upwardly-acting direction of pull of the springs, I58, the angle levers, I45, are rotated in a clockwise direction round a shaft, I44, and by the contact of their noses, I63, with the bar, I64, are held in their normal position. The horizontal pull of the springs, I58, acting on the parts, I52 and I41, is later described.
Furthermore, a connecting link I65 (Fig. 4), is jointed on each side of the lever I45, between which links at their other free ends levers, I66, are jointed. These are swingably mounted on a shaft, I61, which is mounted in the two side walls, 34, so as to be incapable of rotation, and are guided in slots, not shown, in an angle-shaped comb, I68, which is fixed to the side walls, 34, by means of the screws, I10, passing through the lugs, I69, which are downwardly bent at right angles. In Fig. 4 only the right hand fixing is visible. The free upwardly directed ends of the lever, I66, formed to correspond-in Fig. 4 act in a manner to be described later-on the already mentioned number types, 44. The downwardly directed free ends, I52a, of the slides, I52, (Fig. 4) are guided in slots of the comb, I1I, according to Fig. 4, not shown, which at its right-angled upwardly bent lugs, I12, (in Fig. 4 only the right 7 is visible) is fastened by means of the screws, 38,
to both of the printing mechanism frame walls whereby yielding of the slides, I52, laterally is avoided.
The slides, I52, are further provided with recesses, I14, (Fig. 4) through which a rod, I15, projects, which rod is fixed by means of screws to an angle lever, I11, swingably mounted on the right-hand printing mechanism frame wall, 34, by means of a'screw, I16, and also to an angle lever, I11, swingably mounted by means of a screw, not shown, on the left-hand printing .111, form with the rod, I15, the yoke, I11, I15 and I11. The limbs, I18, which are constructed as shown in Fig. 4, are at their free ends bent at right angles and co-act with the cams, I19, tin Fig. 4 only the right-hand caxn'is visible) on the shaft, 51.
The downwardly directed ends, I52a, (Fig. 4), of the slides, I52, are of hook-shape. With the recesses, I88, of the same, a bridge, I8I, of'a U- shaped yoke, I82, I8I, I82, can engage. The latter is swingably mounted by means of its limbs, I82, (of whichin Fig. 4 only the right-hand limb is represented) on the shaft, I83, which is mounted so as to be non-rotatable in the supporting frame walls, 34, of the machine. To the down wardly directed limbs, I84, of the yoke, I82, I8I, I82, two parts, I85, are hired one to each side of each limb.
Between the parts, I85, a roller, .I86, is rotatably mounted, which co-acts with the cams,
I81, on the driving shaft, 51. To the limbs, I84,
of the yoke, I82, I8I, I82, springs, I88, are connected, which with one of their ends are attached to the upwardly projecting limbs of the angle levers, I11, of the yoke, I11, I15, and I11, whereby these and the yoke, I82, I8I, I82, are acted upon in the clockwise direction. Consequently as already mentioned, the right-angled bent lower ends ofrthe limbs, I18, of the yoke, I11, I15, I11, rest against the cams, I19, and the rollers, I88, arranged in the parts, I85, rest against the cams, I 81, whereby the normal position of the yoke, I11,.I15, and I11, as well as of the yoke, I82, I8I,' and I82, is determined. To the downwardly directed hook-shaped parts, I52a, of the slides, I52,-noses, I98, (Fig. 4) are pressed out, which co-act with stops, I9I, on the two-armed levers, I92. The levers, I92, are swingably mounted on the shaft, I93, which is mounted so as to be non-rotatable in the two supporting frame walls, 34, of the machine. On the limbs, I94, of the two-armed levers, I92, noses, I95, are formed, which can co-act with the lugs, I98, formed on the driving segments, 29.
Automatic zero printing In order to print the zeros to the right of a number, the following arrangement'is provided.
On the levers, I92 are lugs, I91, (Fig. 4) which are bent to the left, so that the lug, I91, on the lever, I92, disposed furthest to-the right, rests on the face, I98, of the lever, I92, next to the left, the-lug, I91, of this lever againrests on the lever, I92, lying next to it on the left and so forth.
Springs, I99, (Fig. 4), which on one side are attached to the limbs, I94, of the levers, I92, and onthe'other side to pins, 288, fixed in the machine frame, act upon the levers, I92, 'in the anti-clockwise direction. Through the contact of the noses, I98, of the slides, I52, against the stop faces, I9I, of the levers, I92, by the horizontal pull of the already mentioned springs, I58, the normal position of the slides, I52 is determined. I
The arms, 28I, .of the driving sectors, 29, are
-of fork-shape at their lower ends, and embrace I ing the values, 8 to 9, or with the zero flap, 282.
The zero flap, 282, is swingably mounted on a suitable shaft, 283, which is mounted in any suitable manner on the stop carriage, I5.
, rectangularly upward, and its bent part pro- ,iects upwards through an elongated slot, not shown, in the upper cover plate, 285, of the stop carriage, I5, and is held in its rest position represented in Fig. 3, by means of the spring, 288.
The platen, 33, is mounted in bearings in the carriage frame, 281, of the typewriter machine, 2, which frame is mounted on the rear carriage rail, 288, and on the front carriage rail, 289, in a known manner, and is held against a. carriage draw spring, not shown; acting in a direction of the arrow, A, by means of the known escapement mechanism, 2I8, of the typewriter machine in the required position.
Operation of the printing and impression mechanism sectors 29 may rotate until the noses 32 of the feelers 23- impinge against the upwardly projecting limb of the zero flap 282. Fr'om'an inspection of Fig. 4, it will be evident that during this short rocking movement of the sectors 29, their lugs I96 are not able to act on the noses I95 of the levers I92. Consequently, no actuation of the impression mechanism may take place; If, however, in the two left hand stop rows of the stop carriage stops have been set which correspond to higher values than zero, the stop carriage I5 has moved two steps to the left (as viewed in Fig. 21). Accordingly, the two right hand feelers 23. are free for movement, since the zero flap 282 which together with the stop carriage moved also two steps to the left is no longer in their path of movement;
If now the machine is operated, the two right hand sectors 29 are rocked through a greater angle than the remaining sectors. lugs I98 of the two right hand sectors 29 rock the appertaining levers I92 in the clockwise direction, thereby releasing the lugs I98 of the two right hand slides I52 which by means of their springs I 58 are rocked in the anti-clockwi se direction until arrested by the rod-I15 of the yoke I11, I15, I11. Thus, the recesses I88 of the two right hand slides I52 lie just beneath the bridge I8I of the U-shaped yoke I82, I8I, I82. As soon as the latter is rocked in the anti-clockwise direction by means of the cams I81, the two right hand slides I52 are drawn downwards through the intermediary of the bridge I8I of the yoke I82, I8I, I82. As a result, the toggle joint I45, I is stretched, according to which 'the appertaining layers I86 are urged against the types 44 which through the intermediary of the sectors 29 and the type bars 24 have been brought infront of the upper ends of the levers I88. Provided that a plurality of paper sheets are between the platen 33 and the types 44 owing Hence, the.
earlier in their downward movement, the slides I52 move in relation to the levers I41 thereby stretching the springs I54.
After the cams I81 have released the yoke I82, I8I, I82, the same is rocked anti-clockwise by means of the springs I88, releasing the slides I52 which through the intermediary of the springs I58 are drawn upwards. Thus, the levers I45, I65 and IE6 are restored to their rest position. Shortly prior to the completion of the revolution of the shaft 51, the cams I19 act on the yoke I11, I15, I11. Consequently, the latter. is rocked anti-clockwise, whereby the rod I15 of the same swings the two right hand slides I52 anti-clockwise so that the levers I92, after the return of the sectors 29 to their rest position, may fall in front of the lugs I90 of the slides I52, thus locking the slides in their rest position. The
- sectors 29 are returned to their rest position by the cams 58 through the intermediary of the yoke 54, 53, 54.
On a rail, 2II, fixed to the paper carriage of the typewriting machine, any desired number of column counters, V, are mounted so as to be readily attached and detached, in order that their position longitudinally of the rail, 2, may be arranged to correspond to the column work to be performed.
The column counters, V, attached to the carrying rail, 2, correspond to those described in patent application Serial No. 555,331, and may be set to each type of calculation.
It may be here remarked that the column counters or totalizers, V, and the totalizers, Q and QI, mounted on the adding machine are so arranged in relation to one another that they can be operated together by one and the same. driving sectors, '29, whereby the whole arrangement is constructed in an extremely simple manner and the totalizers and typing text on the platen, 33, may be readily inspected.
If, for example, the amount of 32535, registered in the totalizer Q is to be transferred hundredi'old to the totalizer QI, first of all, the totalizer QI, which at that time is in its zero condition, is displaced through two places to the right (as illustrated inFig. 3a). for the totalizer Q, is setto addition, that is on mark A (Fig. '1). The knob-51c (Fig. 111) is now displaced in the direction of the arrow A until the pointer 51f points to the mark T (total) whereby the total is brought opposite the lever Ill, connected to rod I01 (Fig. 3). Furthermore, the knob 9 for totalizer QI. is also set to addition, that is to mark A (Fig. 1) and the knob' I30 (Fig. 11) is pulled out in the opposite direction to arrow A until the pointer I29 points to mark D (Fig. 10) whereby the cam 3 (Fig. 11) is opposite the lever 4m, connected to rod I22 (Fig. 3).
If now the machine is operated, cam II2a rocks the lever III clockwise, whereby the rod I01 is displaced in the direction of the arrow e. Since the knob I 04a has been set to addition, the recess II 0 of rod I01 has engaged the pin I09 of the totalizer Q. As a result, the totalizer Q, by the displacement of the rod I01 in the direction of the arrow e will be rocked anti-clockwise so that the wheels 1| come into engagement with the segments 28a. It now, while the machine is operated, the sectors 29 are rocked clockwise, the segments 28a turn the wheels H and, through the intermediaryof the wheels 12 and 94, the numeral wheels back to zero which zero position is brought about by the abutment of the noses 15 Thereupon, knob I0la v totalizer Q.
of the wheels 1I against the noses 69 of the tens transfer levers 61 which for this purpose have been locked in their rest position by any suitable locking rod (not shown), preventing the levers 01 from rocking in the clockwise direction.
Accordingly, the segments 281), by means of the sectors 29 are rocked through the same amounts as the segments 28a. Now, by means of the cam II3, the lever H41: is rocked clockwise, whereby the rod I22 is displaced in the direction of the arrow 1. As a result, the totalizer QI, through the engagement of the recess I24 of the rod I22 with the pin I25,'is rocked anti-clockwise, so that the wheels 13 of the totalizer QI will come into engagement with the segments 282). At the same time, the cam II 2a has turned so far, that the lever I I4, by means of a spring (not shown) is rocked anti-clockwise, whereby the totalizer Q, through the intermediary of rod I01 is rocked out of engagement with the segments 28a.
If now, the sectors 29 are rocked anti-clockwise to their initial position, the amount of 32535 will be added into the third to the seventh decimal place from the right of totalizer QI. Therefore, the totalizer QI shows now the amount 3253500 on account of the fact that the units and the tenths place of the same have not been afiected.
Now, it may be assumed that the totalizer QI is held in its displaced position by two decimal places to the right and that in the units and I tenths position, there are figures other than zero.
If now, a total is taken from the totalizer QI and transferred to the totalizer Q it is obvious that the figures of the units and tenths places of the totalizer QI are not transferred, since no segments 28b are opposite these decimal places. Accordingly superfluous places are cancelled while transferring from one totalizer to another although the cancelled figures remain stored in the totalizer from which the total is taken.
By forming the totalizer Q as double totalizer Q, Q, it is possible to store amounts for later application. For this purpose, the double totalizer Q, Q is displaced so far to the right that the units place or the totalizer Q is opposite the right hand sector 29. Any amount may then be transferred from the totalizer QI to the If then the double totalizer is brought back to the position illustrated in Fig. 3a., the amount in the totalizer Q remains unaffected.
In a similar manner the totalizer QI or both of the totalizers Q and QI may be constructed as double totalizers.
