Application filed April 23, 1914. Serial No. 833,986.

T0 all whom it may concern.'

Be it known that I, FRANZ TRiNKs, manufacturer, citizen of the Duchy of Brunsivick, Empire of Germany, residing. at Brunswick, Germany, have invented certa-inneW and useful Improvements in Qalculating-Machines, of which the following is al specilication.

My invention relates to improvements in calculating machines, and more particularly in calculating machines in which the numeral wheels of the Vrevolutions counting mechanism are provided-.With two series of numbers employed respectively for perforining additions and multiplications on the one hand and subtraeti'ons anddivisions on'the other hand, the numbers of the series being alternately arranged about the circumferences of the numeral wheels. In my United States Patent No, 1,088,486 there is illustrated in Fig. 5 a. suitable manner of arranging th numbers of both series. In the operation of the machine only one of the series of numbers of each numeral Wheel4 must be displayed through the peep hole ,while the other one must be covered, for

which purpose a Aslide is provided to cover the peep holes of the numeral wheels and is formed with a single opening for displaying or bringing into vision one number at a time, of each numeral wheel.

Theobje'ct of the improvements is to provide automa-tic means wherebyV the slide for the peep holes is set on the series of regisf tering members Vwhich corresponds to the particular operation of the machine about tobe performed, or, in other Words, to the direction of rotation of the operating crank, when all of the rotating mechanism .is shifted to the zero position.

' It is a further object of this invention to have the rotating counting mechanism shifted one step when passing from the zero point of the series of numbers provided'for addition and multiplication to the zero point of the series of numbers provided for subtraction and division. In calculating machines of the construction now in use a subsidiary tooth must be set by the hand of the operator.

For the purpose of explaining clearly the invention, the same is shown in the accompanying drawings, in which the saine reference numerals have been used in all the views to indicate corresponding parts.

In said drawings, Figure l, is a side View 4tion by means of cam disks 61.

of .the calculating machine with the side Wall of the casing removed andI partly in section, Fig. 2, is a partial plan view of the machine with the cover of the casing partly removed, Fig. 3, isa. side. view similar to that shown in Fig. 1 but showing the parts indierent positions, Figs. 4 to 7, are de-tail views of the machine shownin Figs. 1 to 3, and Figs. 8 and 9, areside views 'of the carrying mechanism which is preferably 4used in the machine showniii Figs. 1 to 7,

the figures showingthe'parts in different positions.

Referring .particularly to the drawings, the calculating machine consists 'of setting disks 41 provided with a plurality of teeth 62 adapted to be shifted in a radial direc- The setting disks are adapted to be rotated from a machine operating crank 40, and when thus rotated the teeth 62, which have-been shifted into opera-tive positions, operate numeral wheels 60 of a registering mechanism. The said numeral wheels are mounted on a slide 64C adapted to be shifted in a direction parallel to. the shaft 41 of the setting mechanism, and said wheels 60 are provided with adapted to operate the laterally shiftable teeth 58. Each of the setting disks 41, ex

-cept the first one from the right, is promechanism 66 -is adapted to be operated by.

resetting mechanism 65 and carrymg means 4constructed in the form of hammers 59 means of a single tooth wheel 67 mounted on the shaft 41" andV may have the construction shown in the United States Patent No. 1,040,059. A However, it is to be understood that my present invention does not relate to this revolution counting mechanism, b ut to a revolution-counting mechanism having numeral Wheels 3, which as shown, are located in the upper part of the machine above the setting mechanism 41, 61.

Through intermediate gear wheels 45, 46, and 47 the revolutions cf. the operating crank 40 are transmitted to a. shaft- 21 which performs the same number of revolutions as said crank, and orA which shaft 21 a single tooth wheel 34 is mounted for axial displacement,as may be' clearlyseen in Figs. 6 and 6*. By means of the said single tooth wheel 34 and through the intermediary of intermediate gear Wheels 42, 43, and 44 each rotation of the 'crank is registered on the nu-. meral Wheel 3, which coperates with sai j single tooth accordingstoA4 the position of the latter, the saidwheel 3 being turned for wardly or backwardly one step upon each rotation of the operating crank. Each of the numeral wheels 3 is` connected with a governing disk 4 having a notch 5 adapted to be engaged by the beveled nose of a pawl 6. Allthe pawls arerigidly mounted to a shaft 7 which is mounted on a rocking lever 23. This arrangement of the pawls permits the same to be operated in unison with the movement of the lever 23 and to drop into engagement with the notches 5 of the disks 4, when said notches 5 are in osition tol receive the beveled noses of saidppawls, which position isshown in Fig. 1. The dropping or downward movement of the pawls 6 may be caused by the influence of the spring pawl 38, see Fig. 7, connected with the pawls 6 and which will be hereinafter more fully described; however, it maybe found desirable to have the pawls to drop by gravity. In the position of the pawls 6 as shown in Fig. l, the zeros of the series of numbers correspondin to. additions and multipli-cations are disp ayed through peep holes formed in a slide 2. Projecting from the pawl 6 co operates with the numeral wheel of the lowermost order, is a pin 8 which operates a lever 9 journaled-in the side wall of the machine casing said lever 9 being connected bya' link 10 with a rocking lever 14 mounted on the shaft 42 of the intermediate gear wheels 42 and carrying a geai`\vheel 11. When the pawltmoves downwardly, the pin 8 rocks the lever 9, the link 10 and which, in turn moves the lever 14 downwardly, so that the gear wheel llis shifted bodily into the path of two teeth 12 and 13 which take part i'n the rotation of the machine operating crank 40, this position of the parts being shown in Fig. 1. The gear wheel 11 is in mesh with the intermediate gcar`wheel 42, so that the revolutions counting mechanism Bcan be shifted one step by means of 'either one of the teeth 12 or 13. In order that during this shifting operation the lever 14 may not be rocked with the gear wheel 11 out of position for engagement with the teeth 12 or 13, a spring actuated locking pawl 15 is provided and formed with two shoulders adapted to engage with an arm 14', of the lever 14, respectively, in its rocked and normal positions. Projecting from the arm 14" of the lever 14, is a pin 16 adapted to rock a bell crank lever 17, 1T', mounted on a-shaft 1li. clockwise when the gea r wheel l1 rocked into the operative position 24, and which, when rocked.' upward, shifts .the locking pawl 15 into non-locking position by acting'on a pin 25 connected with the said pawl. Thereby the gear wheel 11 is moved into the inoperative position shown in Figj3, and the lower arm 17 of the lever 17 releases the finger 20 so as to permit the same to be returned into normal position by suitable means such as a spring (not shown). Therefore the teeth 12 and 13 and the finger 20 are inoperative during the following addition or multiplication, so. that they can not affect the result of the calculation registered on therevolution counting lmechanism 3. i

The carrying mechanism is shown in Figs. l, 2, 8, and 9. As shown each of the' intermediate gear wheels 43, which are constantly in. engagement with the numeral wheels 3, is equipped with a pin 48. When one. of the numeral wheels 3- passes from its zero position toits nine position or vice versa the corresponding pin 48 acts on a cooperating rocking lever 49 in such a way as to rock a gear wheel which is mounted on the lever 49 and which is always in engagement with the intermediate gear wheel 42 of the next higher order. Thereby the gear wheel 5() is shifted into the path of teeth 51 which take part in lthe rotation' of the shaft 41' of the machinev crank, 'so that when rotating the setting-disks 41 one of the teeth 51 engages with the gear wheel 50 and effects the carrying operation through the intermediate gear wheels 42, 43, 44. rl"he gear wheel 50 is held in its rocked position by means of a locking pawl 53 which. is shifted by a spring 5 2 below the elevated right hand end of the lever 45). At theend of the carrying operation the locking pawl 53 is returned into initial position by means of a bell crank lever 56 which rocks an arm 5.3 connected with the shaft 54 of the lock ing pawl in the direction of the arrow 68 shown in Fig. 8. For operating the bell crank lever 56 a cam disk 57 is provided which takes part. in the rotation of the setting mechanism 41. After the lockingpawl :33 has been rocked into non-locking position, a spring, for example the spring 52, rorlts the lever 49 downwardly and in contact with the lower shoulder of the pawl 53. Thus all the parts are returned into normal prsitions, and th(` transmission wheel 45() is out of the path of the teeth 51. When. the numeral wheel passes again from its nine position to its zero position,

pin 19 on which a tinger20 has a 'los or .vice versa, the same operation is re` pin and slot connections which permit slight' rocking movements of the pawls relatively to said Shaft, which movements arefsuiiicient to permit the' pawlsto move into locking en agement with the coperating levers 49.

fit is desired to v,perform a subtraction or division' after the registering mechanism has been reset all the numeral Wheels 3 must be rotatediso far-that the pins 48, 'which start the carrying operation are moved from the front-'sdes'of the levers 49 t6 the rear sides thereof because, otherwise, 'the first rotation;

of-a numerallwheel 3 caused by the single tooth 34 wouldresultin a carrying operation, .vvhile such a carrying operation should take placeafter tcnoperations of the crank of the'machine. Furthermore, the slide 2- Which is' formed'with the peep holes must be set in. such away that instead ofthe `zeros corresponding to ,the additions and multiplications the zeros corresponding to the subtractions and divisions are displayed .through 'the peep holes. In my improved machine these operations, to Wit, the -rotation of all the numeral Wheels and the setting -of the-slide formedwith the peep holes are automatically performed, without operafio tionof any of the-parts by hand. For this purpose-the following-mechanism is provided: vIn explaining the mechanism I shall startfrom the normal position of the parts shown in Fig. l1, inwhich,in the zero position-'of the numeral wheels 3, th e noses of all the pawls 6 engage in the notches' of governing disks 4 and the-whel 11 .is in the path of the teeth 12 and 13. When rotating the shaft 21 to the left or in the direc'- tion-of the arrow 'w shown in Fig. 1 for per. .45;

forming a division o'r subtraction, the erected finger 20.strikes against {those-126 ofthe lever 23' and rocks the said lever' abou-tits shaft 24 inthe direction of the arrow a: shown in Fig. 1. Thereby the pawl 6 which is connected with the opposite end ofthe lever 23 is moved in the direction of the'arrow y shown in Fig. 1 and. into the :position shown in Fig. 3. l The lever 23 is adapted' to'be locked in lts end positions by alocking pawl 27 adapted to engage in' 'either one of notches 28 and 29 of the lever 23. By shifting the -pawl 6 the slide -2 --Which is provided Withthepeep holes and has a' rocking support on the shaft 1 is lifted, an upwardly curved arm 30 connected with the saidslide being forced downwardly by the rearward movement of the shaft-7 carrying th e pawls 6.- By this movement or operationof thgpeep hole slide -2', the number ,yychichoriginellylffwas dis- .through the peep played'through the peep holesand which corresponds to additions and multiplications tion through' the intermediary of the gear wheel 11 and the intermediate gear wheels V42, 43, and 44. This carrying operation is transmitted through the pins 48, thelevers 49, the gear Wheels 50, and the teeth 51 (Figs. 2 and 8) to' all the other numeral wheels 3, which is necessary in order that the zeros of the series of numbers corre- Spending to the division are displayed holesand in order to bring the carrying moans, thatis the pins 48 (Figs. 2 .and 8,) which are common to both series of numbers, to the opposite sides of the levers 49, so that carrying is performed in the co-rrect position `when the series of numbers corresponding to the division are-used, the numeral wheel3 is advanced by the single tooth 34 one step for each revolution of the crank of the machine, in the same way as when performing additions and multiplications.

Whenturning the crank clockwise the finger 2O rocks the lever 23 through the intermediary of the pawl 22 intothe position shown. in A slide 2 which is under the action of the the tooth 13 can perform acarrying operaloq Fig. 1, whereby the peep hole spring 3l, isturned into "the position corresponding to the addition andV multiplication.

' In my. improved machine the driving -member 34, connected-With the machine crank 4l and provided for registering the number of'rotations of the crank, must come into operation as nearly as possible immediately after starting .the operation' of the crank 41. In order that this be the case in both directions of rotation of the crank suit-- able means are provided, such as those shown in Figs. 6 and 6". -To the shaft 21 a sleeve 32 is slidably connected which` is'provided with two teeth 34 actuatedby arc-oinmon spring 33. These teeth 34 are so supstarted. 'When rotation of the crank shaft ported byfixed projections 35 of the sleeve l takes place in the opposite direction, -the tooth 34 which is located at the right is operative, while the left hand tooth yields to the gearing.

norderthat when shiftingthe pawl 6 -in the direction of the arrow y shown in Fig. 1- .the numeral wheels 3 may not be rotated the mechanlsm shown inI Fig. 7 is p rovided.'

This mechanismA has, also, the function to lift the beveled noses of thepawls 6 out of 4engagesin l'a notch of. a diskA 39 rigidly con nected with the shaft 21. Therefore, when,

- the crank is rotated either to the right or to the left the pawls 6 are lifted by the disk- 39, the pawl- 38, 'and the rod 37 to such an extent that the-disks 3 and 4 can not be carried4 along' when the pawls 6 move in the direction of the arrow y'shown in Fig. 1.

For resetting the revolutlons counting mechanism' 3. a wing nut- G9 is provided.

which is shown in Fig, 2. The operation of the -present invention' i may be described as follows:l When the numeral wheels 3 are reset by the turning of the Wingnut 69, the crank handle may be turned in a. direction corresponding4 to the work to be done bythe machine; that is, the handle may be turned to the left of ,its position shown in Fig. l'when` it is desired to add' or multiply, o r it may be turned to the right Awhen it is desired to subtract orY divide. This preliminary movementi of the handle shifts the slide 2te such a'posi-ti'on. that the proper" numerals will be exposed or displayed through its peep openings.

Said shifting is effected in the following;

manner: When-it is desired to addor multiply, the .crank handled() is moved to the left ofitsposition shownin Fig. 1,. thereby .rotating 'with it the disk 41 and the gear 45, which rotates the teeth 34 clockwise through the'intermediate gears 46 and 47. The teeth 34 engage upon each lrotation thereof withthe gear 42. which vrotatesl the same one step to `effect the Vconsequent stepby-step. rotating movement of the numeral disk 3 and the notched disk 4, through the intermediate gear 43.v This rotation of the disks 4 will 'bring the notch 5 thereof into position to be engaged by the pawls 6 which will be moved down\vardly'bvthe influence of the spring pawl 38 into said notch. Upon the downward movement of the pawl 6, the projection Bengages with the lever 9. thus moving the same upon its pivot downwardly to actuate the rocking lever 14 carrying the gear 1l meshing with the gear 42. the gear 11 being moved in the path of the projcc tions 12 and 13 of the disk 41. At this point, the machine is now positioned to register and. as the. disk @rotates the teeth 12 or 13 wlll engage with the disk 11 to impart astep-by-.step rotting movement 'to the1 latter, which, in, turn, imparts said movement to the-gear 44, which will rotate 'loI the nnmeralwlieel 3 upon 4each rotation of the dlsk 41 and. thus cause.. the counting mechanism to'register, as will be clearly understood. The gear 11 is held in the path. of the teeth 12 and 13' during the \coun tingi 75 operation of the mach-ine by the locking' pawl' 15l which is operated inthe following manner: When the saidgear is moved downwardly, the rear end of the rocking lever 14 is moved upwardly ,in a direction 80 indicated bythe arrow Fig. 1, which rear end carries a pin 16 adapted to. engage with the upper end of the bell cra-nk lever 17, which latter engagement will'move the end 1.7 of the bell crank lever in the position shown in ig. 1 to erect the finger 20 to e'ect the engagement of the latter with the pawl 22. When- Vthe pawl 22 is engaged by the finger4 20, theisame ismoved upwardly' and engageswith the p in 25 ofthe pawl 90 15 and moves. the sauge rearwardly 'against the tension of its spring so that therear end of the rocking lever 14 will rest in the uppershoulder of the pawll, whereby the lever' 4 .14 is locked i`n the position shown in Fig. 1 95 and the'gear 11 is held in the path of the : teeth 12 and 13. The above-operation will permitan addition or multiplication oper ation of the machine and the slide 2 will be Aheld in position to display through 'its peep 100 hole the proper series ofqnumerals for such operation.

When 2i, is desired to use the machine for subtractingand dividing, the numeral disks 3 are reset by the wing nut 69 and the crank 105 handle 40 is rotated to the. right or anticlockwise.V This rotation of the crank liandle will rotate thc shaft 21 in the direction of the arrow tu,A Fig. 1, and the finger 20 will engage with the projection 26 of therocking 110 almv23 which will rotate the arm 23 in the direction of the arrow w, and, in con se quence, movesthe shaft 7 in the direction of the arrow y. The shaft 7 carries with it the pawls 6 which are raised by this rnove- 115 ment of the shaft from the notphes 5 and disks 4. The shaft' 7, when moved in the direction of the arrow y, engages with the upwardly and rearwardly extended arm 30 and moves the same downwardly against the v tension of the expansion spring 31, and consequently, effects a shift-ing of the slide 2 whereby suitable subtraction and division seriesof numbers on'the disks 3 4are displayed through the peep hole of said'slide. 125 By turning the crank handle clockwise. the finger 20 will engage with Athe pawl 22 to, so operate the lever 23 upon its pivot 24 as to cause the same o assume the position shown in Fig. l, whereupon the spring 3l 13o 'the slide 2 to be moved into play the addition and multip ication numerals of the numeral wheel 3.- 1
