3,026,030 CONTROL MECHANISM IN ADDING AND CALCULATING MACHINES Helmut Gelling, Ulm (Danube), Germany, assignor to Walther Buromaschinen Gesellschaft m.b.H., Gerstetten, Wurttemberg, Germany, a firm Filed Nov. 18, 1957, Ser. No. 697,003 Claims. (Cl. 235--79) The invention relates to control mechanisms in adding and calculating machines for indicating the amounts introduced into the machines in the form of items to be summed up with machines having oscillating differential actuators. The latter are moved, during the first half of the cycle of operation of the machine, up to the adjusted setting means such as keys and are returned, during the second half of the cycle of operation, into their home position whereby the transmission of the adjusted amount to the totalizer takes place.
Control mechanisms of this kind are mostly directly adjusted by means of the setting members of the machine or by means of intermediate members connected therewith. Upon releasing the setting members at the end of the cycle of operation or previous thereto also the control mechanism will be automatically released so that after the accomplishment of the calculation, especially with non-printing machines, the introduced value no longer can be read ofl.
In order to eliminate this drawback and to impart further objects to the setting control mechanism, according to the invention, the control mechanism is adapted to be directly brought into and out of mesh with the oscillating differential actuators cooperating with the totalizer. It is retained in mesh with the actuators during the return movement of them in order to be adjusted to the introduced value. The control mechanism is released in unmeshed state during the void movement of the actuators at the beginning of the following cycle of operation so that after finishing of the calculation the introduced value, eg the multiplicand, besides theother .United States Patent 0 values of the calculation, e.g. the multiplicator or the product, is indicated.
The control mechanism according to the invention is the control mechanism is brought into mesh with the actuators, being in their zero position, by means of a particular setting means whereupon the indicating wheels of the control mechanism are returned to zero, the actuin the control mechanism.
Further, the invention in connection with total taking,
clearing or subtotal taking, permits to transfer the value contained in the totalizer to the control mechanism making the value readably in the latter, which possibility is of particular importance with non printing machines.
Further features and objects of the invention can be gathered from the following description of an embodiment of the invention.
In the accompanying drawing:
FIG. 1 shows a front view of the control mechanism.
FIG. 2 is an elevation view of the machine being in the position of rest.
FIG. 3 is an elevation view of the machine being in a working position.
FIG. 4 shows schematically the driving mechanism of the machine.
The control'mechanism is movably mounted between rigid side walls 1 and 2 (FIG-1) of the machine. Its frame 3 is crossed by'three bars or' shafts i5, 6 and,7, respectively (FIG. 2) which extend through the side ators being adjusted thereby to the value which has been walls 4 of the frame 3 and being mounted therein. The bar 7 forms the shaft of the indicating wheels 9 having indicating rollers 8 and being permanently in mesh with intermediate wheels 10 having thirty-two teeth and being rotatably mounted on the bar 5 as shaft and adapted to be brought into and out of engagement with the oscillating differential actuators 11 (FIGS. 1 and 4) of the machine by means of upward and downward movement of the engaging mechanisms.
This movement is effected by a parallelogram linkage which consists of a pair of arms 12, 13, each being secured to one of the ends of the bar 6 and by means of a pair of arms 14 located above the pair 1 2, 13 each being secured to one of the ends of the shaft 7. The arms 12, 13 are secured at their outer ends to a shaft 15 (FIG. 2) rotatably mounted in the side walls 1, 2 ('FIG. 1) of the machine, and the arms 14 are secured with their outer ends to a shaft 16 likewise rotatably mounted in the side walls 1 and 2.
The frames formed by the shafts or bars 6, 7, 15, 16, respectively, and arms 12, 13, 14 effect, upon their rocking about the shafts 15, 16, an approximately vertical upward and downward movement of the control mechanisrn.
The rocking is effected by means of a downwardly extending projection 17 of the arm 12 which is connected with a link 21 by means of a pin 18. The projection 17 is actuated by a tension spring 20 which tends to move back the control mechanism into its upper disengaged position. The link 21 is attached by means of a pin 22 to a connecting bar 23 pivotally connected by means of a pin 24 to a lever 25 which is rotatably mounted on a stationary pin 26 at the side wall 1 of the machine and can be rocked clockwise by means of a key 27. A nose 28 of the link 21 coacts with a lug 29 of a drive rod 31 oscillated by the machine drive mechanism more fully described later. Besides this the projection 17 carries a lug 40 which cooperates with a nose 50 of a second drive rod 19 (FIGS. 1 and 4) which is likewise oscillated by the machine drive mechanism, whereby also a rocking of the control mechanism takes place. The movement of the drive rod 19, however, can take placein another point of time as by the movement of the drive rod 31.
To each of the two ends of the shaft 5 a lever 32 is secured and the two levers 32 are connected with each other by a bar 33 and form together with the shaft. 5 and the bar 33 a rocking frame. One of the two levers 32 is provided with a projection 34 which is pivotally connected with a connecting rod 36 by means of a pin 35. The connecting rod 36 is linked by means ofa pin 37 to a crank rod 38 connected by a crank pin 39 to a crank arm 41, rotated in the direction of the arrow 42. The pin 37 is guided by means of a roller 43 mounted on it in a horizontal guidance 44 provided in a frame side wall of the machine. The bar 33 as Well as the bar 6 extend through the inner spaces of the intermediate wheels 10 divided into two parts by two spokes 45.
On clockwise rocking of the bar 33 all of the intermediate wheels 10 are carried along by means of the lower spokes 45 whereby these spokes are moved up to the bar 6. In this position the indicating wheels 9, permanently in mesh with the intermediate wheels 10, are positioned to zero. To the two ends of the shaft 7 there are secured two arms 30 connected with each other by a locking rail 46 which cooperates with the intermediate wheels 10. The frame formed by the parts 30, 7, 46 is under the action of a spring 47 which tends to draw the locking rail 46 into engagement with the teeth gaps of the intermediate wheels 10. One of the arms 30 is provided with a downwardly extending projection locking rail 46 against the action of the spring 47 out of the intermediate wheels 16 after they have been locked,
in the meantime, by the engagement with the differential actuators 11 against accidental displacement.
At the very beginning of the cycle of operation first a movement to the left in the sense of the arrow 52 and later a movement in the opposite direction is imparted to the'drive rod 31. This oscillating movement is without influence to the control mechanism as the nose 28 is out of the path of the lug 29. After the movement of the drive rod 31 to the left the movement of the crank arm 41 follows, whereby the bar 33 is rocked clockwise and all intermediate wheels 10 are taken along until the spokes strike against the shaft 6 so that the indicating wheels 9 are adjusted to zero.
The driving means for the drive rods 19 and 31 and the engaging movement of the totalizer are shown in FIG. 4. A main drive shaft 55 (FIG. 4) is rotatably mounted in the machine frame and has fixed to it an arm 56 and two cams 57, 58. Arm 56 has fixedthereto a pin engaging a cross slot 60 of a drive rod 61 to the right hand end of which and to the similar drive rod at theother side of the machine is fixed a restoring bar 54 which extends through slots of the differential aoctuators 11, which are urged by springs 64 to the left and being restored to their home position, represented in FIG. 4, by the back movement of said restoring bar 54.
The different actuators are guided by four-edged bars extending through slots of the actuators.
The totalizer wheels 63 are rotatably mounted on a shaft 62. The shaft 62 is supported by two bell crank levers 65 which are pivotally mounted on stationary'pins 66, said bell crank levers 65 are linked at their upper ends by pins 67 to links'68 pivotally mounted on stationary pins 69.
On the connecting pins 67 pawls 71,7'2 are fulcrumed which cooperate with pins 74, 75 of the drive rods 19, 31 which are guided at their right hand ends by stationary pins engaging slots 76.
At the left hand end the drive rods 31, 19 each carry antifriction rollers 78 and 77, which cooperate with the earns 57 or 58, respectively, in such a way that the drive rods perform oscillating movement on each revolution of the main shaft 55 in a differently timed manner. To each pawl 71, 72 an operation key 73 is associated by depressing of one of which the drive rod 19 or 31, respectively, is coupled with the pin 74 or 75. The pins 67, the links 68 and bell crank levers 65 form toggle joints, and on moving the pins 67 to the left by means of the cams 57 or 58, respectively, the totalizer wheels 63 will be moved downwardly in mesh with the differential actuators 11.
moved 'set pin carriage .84, the set pins of which being setby digital keys 85 in a known manner.
The described mechanism operates as follows: 7 (a) Introducing of an adding item or another value of mesh with the differential actuators ll and the indie eating wheels are adjusted to zero or assume an amount position coming from the preceding cycle of operation. The nose 23 is out of the path of the lug 29 and the crank pin 39 assumes its right hand dead center position, so that the bar 33 is in its uppermost position.
After the amount to be added has been introduced into .jection 17, the nose 51 strikes the lug 49 and lifts the the amount keys and the set pins have been accordingly adjusted and the pawl 71 is coupled with the, drive rod 1 by depressing the associated key 73 the cycle of operation is started. The movement of the drive rod 31 which begins immediately at the beginning of the cycle of operation is without effect with respect tothe projection 17 (FIG. 2). Then, by moving the restoring bar 54 to the left the void movement of the actuators 11 in the direction of the arrow 53 (FIG. 2) follows, during which the actuators move under the action of their tension springs 64 up to the adjusted set pins of the set pin carriage. During the same space of time the crank arm 41 rocks the bar 33 clockwise and positions the indicating wheels to zero. Then the drive rod 19 begins its movement and rocks clockwise the projection 17 by means of the nose 50 (FIG. 2) and the lug 40, whereby the control mechanism is engaged into the actuators 11 (FIG. 3); a the same time the totalizer will be brought into mesh with the actuators by means of the drive rod 19. Now the actuators 11 are again restored into their home'position in a direction opposite the sense of the V arrow 52 by means of their restoring bar 54, whereby the amount to which the actuators have been adjusted is transmitted to the intermediate wheels 10 and the indicating wheels 9, so that the indicating cipher rolls indicate the introduced value. During restoring of the differential actuators also the introduced amount is added to the totalizer wheels 63.
During the downward movement of the control mechanism the locking rail 46 has been lifted out of the intermediate w'heels 10 by means of the nose 51 and the lug 49. Simultaneously with the restoring of the actuators 11 further turning of the crank arm 41 effects the return rocking of the bar 33 into its home position. At the end of the cycle of operation the control mechanism is again brought out of mesh with the actuators whereby the intermediate wheels 10 and the indicating wheels 9 are locked again by means of the locking rail 46. During the position of rest of the machine the control mechanism therefore shows the value introduced during the preceding cycle of operation while, in the case of a multiplication or division, the multiplicand or dividend is shown by another-indicating mechanism of the machine and the new total appears in the totalizer.
is finished.
(b)'Total taking.ln total taking cycles of operation a storing mechanism or from an auxiliary totalizer not equipped with indicating rolls or otherwise to store a value contained in the totalizer and to render it readable after the finishing of the cycle of operation. This can be effected without any further means by the described control mechanism. V a
On total taking the totalizer which has been connected with the drive bar 31jby means of the pawl 72 will be brought into mesh with the actuators already at the beginning of the cycle of operation-and the actuators are,
'underthe action of their springs, moved back until the wheels of the totalizer arestopped into their zero posie amount 'into'fite'machine.-In the position of rest of r in FIG. 2 in. which the intermediate wheels 10 are out 1 the machine the parts assume the position represented tion. This is effected by coupling the pawl '72 (FIG. 4) with the drive rod 31 by depressing the associated key 73, whereby the totalizer wheels 63 are engaged and disengaged into and out of the diiferentialactuators in due time. In this manner, the amount which is contained in'the totalizer 63 will be transmitted to the actuators 11. described above, the intermediate wheels 16 remain,
The calculation values can be read off when the cycle of operation during the void movement of the actuators 11 to the left out of mesh with the actuators and are brought into mesh with them by means of the drive rod 19 short before the actuators 11 begin their return movement towards the right into the Zero position. Upon this return movement therefore the total-values or the like taken up from the actuators are transmitted to the intermediate wheels and therewith also to the indicating cipher rolls 8, so that they indicate the related totalizer values or the like during the following position of rest of the machine.
'(0) Transmitting back-The described control mechanism can also be used for re-transmitting an amount coming from the preceding cycle of operation into the diiferential actuators in order to use it in .any manner. To this end it is only necessary to depress the key 27 (FIG. 3) previous to the beginning of the cycle of operation. Thereby the nose 28 will be adjusted into the path of the lug 29 of the drive rod 31 so that immediately after the beginning of the cycle of operation the lug 29 rocks clockwise the arm 17 thereby bringing the control mechanism into engagement with the actuators 11. The totalizer remains out of mesh with the actuators 11.
By the subsequent clockwise rocking of the bar 33 the rotation of the intermediate wheels 10 and the indicating rollers 9 into their zero position takes place which is assisted by the action of the spring of the actuators and whereby the amount which has been contained in the cipher rolls is transmitted to the actuators and then, before the return movement of the actuators 11 into the zero position, the totalizer or the like is engaged into the actuators, this amount is transferred to the totalizer by the return movement of the actuators.

3. in a calculating machine according to claim 1, said engaging means for said intermediate wheels comprising a parallelogram linkage, a link pivotally connected at its one end with said linkage, a nose integral with said link, said totalizer engaging mechanism comprising a drive rod adapted for controlling total taking of the totalizer and movable in one direction at the very beginning of each cycle of operation, a lug on said drive rod cooperating with said nose, a special key, operative connecting means between it and the other end of said link, whereby upon depressing of said special key said link is moved with its nose into the path of said lug'and upon the movement of said drive rod the intermediate wheels are engaged with the actuators, whereby the zeroizing of the intermediate wheels is eifected and the amount contained in the intermediate wheels is transmitted to said actuators.
I integrally mounted in the control mechanism, a movable bar, these two bars extending through the inner spaces of said intermediate wheels, spokes at said intermediate wheels cooperating with said integral and said movable bars, means for rocking said movable bar about the axis of the intermediate wheels comprising a crank gear for effecting an oscillating movement of the movable bar, whereby at the very beginning of the cycle of operation the movable bar displaces the intermediate wheels by means of said spokes until the spokes strike against the integral bar and the movable bar is subsequently returned by said crank gear freeing said intermediate wheels.
5. In a calculating machine according to claim 1, a locking rail cooperating with said intermediate wheels, an axle rotatably mounting said indicating rollers and rockably mounting said locking rail, a lug rigidly connected with said locking rail, said engaging means for said intermediate wheels comprising a rocking lever having a nose cooperating with said lug, whereby on rocking the rocking lever for engaging the intermediate wheels into said actuators said nose strikes against said lug lifting said locking rail out of said intermediate wheels, while on rocking the rocking lever in opposite direction for unmeshing said intermediate wheels said nose releases said lug permitting the locking rail to engage into said intermediate wheels.
