FRANZ TRINKS, OF BRUNSWICK, GERMANY.
Application filed April 26,
To all whom it may concern:
Be it known that I, FRANZ TRIXKS, manufacturer. citizen of the Duchy of Brunswick, Empire of Germany, residing at Brunswick. Germany, have invented certain new and useful Improvements in Calculating-Machines. of which the following is a specification.
My invention relates to improvements in calculating machines. and more particularly in calculating machines of the class in which revolutions counting mechanism is provided which is equipped with resetting devices, and in which the numeral wheels have two series ofnumbers arranged around their circumference, the numbers of the said series being displaced from each other. A calculating machine of this class is described in the patent of the United States No. 1,088,l86 granted to me February 24, 1914:. As described in the specification of the said patent the numeral wheels of the revolutions counting mechanism are equipped with pins or noses which cooperate with rocking carry ing levers or hammers and are adapted to be brought from the upper to the lower sides of the heads of the said carrying levers or hammers (or vice versa from the lower to the upper sides thereof) by rotating the numeral wheels through an angle of nearly 360 degrees.
The objectof the improvements is to provide mechanism which is particularly suitable for imparting th said rotary movement to the numeral wheels.
lVith this and other objects in view my invention consists in the matters to be described hereinafter and particularly pointed out in the appended clalms.
For the purpose of explaining the invention two examples embodying the same have been shown in the accompanying draw- 'ings, in which'the same letters of reference have been used in all the views to indicate corresponding parts.
In said drawingsFigure 1, is a crosssection of the calculating machine showing the revolutions counting mechanism. Fig. '2. is a side view of the machine showing the parts for operating the resetting mechanism and rotating the numeral wheels through an angle of a little ess than 360 degrees. Fig. 3, is a partial plan view of the part of the calculating machine containing the revohi tions counting mechanism partly in section and with the cover of the casing removed,

and Fig. l. is a side view similar to that shown in big. 2, and showing a moditicationof the operating mechanism. Fig. 5 is the class of calculating machine shown in the drawings. and that also in other respects various changes may be made in the general arrangement and construction of the parts of the machine within the gist of my invention. cation of the said patent. the calculating machine is equipped with setting mechanism adapted to be rotated by means of a machine crank and consisting of'setting disks each of which is provided with a plurality of teeth which are adapted to be shifted into or out of operative positions by means of rotary cam disks, the said setting disks being adapted to transmit the values set thereon through transmission wheels to a main registering mechanism which is mounted on a shiftable carriage. Coaxially of the said registering mechanism a revolutions counting mecha nism is provided which is adapted to register the number of the revolutions of the machine crank. These parts are known in the art and they have been fully shown in my aforesaid patent and also in my Patent No. 1,088,486. Therefore I deem it not necessary to describe the general construction of the machine more in detail.
Referring now more particularly to those parts of the calculating machine to which my invention more particularly relates, the revolutions counting mechanism comprises numeral wheels 1 each of which has two series of numbers printed thereon, which numbers are displaced from each other, as is shown in Fig. 3. Each of the numeral wheels is rigidly connected with a gear wheel 2 having twenty teeth and meshing with an intermediate .gear wheel 3. The intermedi ate gear wheels are adapted to be operated from driving gear wheels which are equipped -ach with the teeth and are secured to the shaft 6 of the setting mechanism (not shown). For resetting the numeral wheels 1' a shaft 7 is provided which is provided As described in the specifiwith a number of teeth 8 cooperating with noses 9 secured to the numeral wheels 1, said teeth and noses providing the resetting members. 'ihe shaft 7 is adapted to be shifted in longitudinal direction so as to be brought with its teeth 8 into resetting posi tion relatively to the noses 9 secured to the numeral wheels, as is known in the art.
Apart from the resetting shaft 7 a second resetting shaft 5% is provided which is connected with the resetting shaft 7 by gear wheels 55 and 56 having a ratio of transmission of 1 to 2, so that for each complete rotation of the shaft 7 the shaft 54 performs two complete rotations in the opposite direction. For shifting the shafts T and 51 in longitudinal. direction and into resetting positions in opposition to the usual springs acting thereon cam sleeves l3 and 57 are provided which cooperate with noses 11 and 65 connected with the shafts 7 and 5% respectively. The cam sleeves 13 and 5? are rotatably mounted and are adapted to be looked as against rotation by means of spring pressed pa wls and 59 engaging in notches 57" and 13 made in flanges 13 and 57 respectively, the form of the said pawls and notches being such, that when rotating the shaft 7 in the direction of the arrow shown in Fig. 2 only the sleeve 1 is locked while the sleeve 57 takes part in the rotation, and vice versa. Therefore when turning the shaft 7 by means of a wing nut 10 secured .thereto only one of the resetting shafts 7 or 5% is shifted in longitudinal direction and into resetting position relatively tothe nu- Ineral wheels, so that when turning the wing nut 10 only one of the resetting shafts 7 or 5% is thrown into operation.
Apart from the gear wheel 56 gear wheels are mounted on the shaft 5%, and the said gear wheels .30 are in mesh with the gear wheels :2 connected with the numeral wheels 1. The diameter of the gear wheels is one-half the diameter of the gear wheels 2. The shaft 5% is provided with pins 61 which are adapted to cooperate with noses (30 secured to the gear wheels (30. Normally the said pins and noses are not in positions for resetting engagement with one another. and they are brought into such positions by shifting the shaft 54- in longitudinal direction, as is known in the art. In the present case the said noses and pins are disposed in r such a way. that in the normal positions shown in the figures they are displaced relatively to one another a distance. corresponding to one tenth of the circumference of the gear wheels (30, when once, rotating the shaft 5! from the normal position shown in the figures through an angle of 560 degrees they are carried along only through ninetenths of the said angle, and when twice rotating the shaft the gear wheels so are rotated through an angle of nineteen tenths of 720 degrees, so that the gear wheels 2 the diameter of which is the double of that of the gear wheels (30 perform only nineteen twentieths of a complete rotation. The reason for thus operating the gear wheels will be explained hereinafter.
To the pawl 58 a stop member 63 is secured which is adapted to be rocked to the left and into cooperation with a stop 64: c0n-- nected with the resetting shaft 51, when the pawl 58 is rocked to the left by rotating the wing nut 10 in the direction of the arrow 1 and imparting resetting operation in the opposite direction to the shaft 51. Thereby the stop plate. (33 prevents the resetting shaft 5% from being shifted backward in longitudinal direction by the spring acting thereon, as would otherwise be the case when the nose Goof the shaft 5% which performs two revolutions for each revolution of the shaft 7 has completed the first revolution and arrives again in position for engagement with the corresponding notch 66 of the sleeve 57, in which position of the nose the shaft can be shifted in axial direction by the spring acting thereon. When the resetting operation is completed and the shaft 54 has performed two revolutions and the pawl 58 gets again into engagement with the notch 3", the stop plate 63 releases the shaft 5% and permits the same to be returned into normal position in which the resetting pins (31 are outof position for engagement with the noses The operation of the machine is as follows: In the nornial position of the parts shown in the figures the numeral wheels 1 are adapted to perform additions and multiplications, and the zeros of the saidnumeral wheels which have been indicated in Fig. 3 by the letter a. are displayed through the peep holes 19, and the pins e2 by means of which carrying takes place are located at the upper sides of the carrying levers or hammers 47. F or resetting the numeral wheels after an addition or multiplication has been made the wing nut 10is turned in the direction of the arrow :0. The sleeve 13 is locked as against rotation by the pawl 58, so that the shaft 7 is shifted in longitudinal direction "and resetting takes place in the usual way, while the sleeve 57 is not locked by its pawl 59, so that the shaft 54 which is being rotated from the shaft 7 in the opposite direction is not shifted and remains inoperative. If it is desired to set the numeral wheels 1 in such positions that the other zeros are displayed through the peep holes as is necessary for performing subtractions and divisions, the wing nut 10 is rotated in the opposite direction and in'thc direction of the arrow 9 shown in Fig. 2. Now the sleeve 13 is not locked by the looking pawl 58 as againstrotation, so that the resetting shaft 7 is not shifted into resetting position. while the resetting shaft 51 the sleeve 57 of which is locked by the pawl 59 is made operative. As stated before the shaft 51L performs two rotations. and as the pins (51 and noses 60 are displaced relatively to each other. during the first rotation of the said shaft the wheels 60 are carried along through nine tenths of the circumference, and during the second rotation they are carried along through ten tenths of the circumference. As there is a ratio of transmission of l to 2 between the gear wheels 60 and 2 the said revolution through nineteen tenths of the circumference causes the gear wheels 2 to rotate through nineteen twentieths of the circumference, so that instead of the zeros indicated by the letter a the Zeros indicated by the letter Z) are displayed through the peep holes 19. During this operation the numeral wheels 1 arerotated in the direction of the arrow y shown in Fig. :2, and the pins 42 are brought from their positions above the heads 17 into the positions below the said heads. At the end of this rotation the stops 1 and 60 are located exactly in opposition to each other, so that now by each further rotation of the wing nut 10 in the direction of the arrow 3 all the numeral wheels which may have been brought out of their zero positions are carried along by the resetting shaft 51 and the gear wheels 60 thereof and brought into the proper zero or initial positions.
If it is desired to set the other set of zeros into initial position, all that is necessary is to rotate the wing nut 10 in the direction of the arrow :20 shown in'Fig. 2, in which case the resetting shaft 7 is operative so as to return the parts into the normal positions shown in the figures. v
The example shown in Figs. 1 and 5 is distinguished from the construction shown in Figs. 1 to 3 in this respect, that the resetting shafts 7 and 54s are coupled by gear wheels 67 and 6S ofeven diameter, so that they perform the same number of rotations. Accordingly, also the gear wheels 60 and 2 have the same diameter. The resetting pins 61 of the shaft 5% and the noses 60 of the wheels (50 must be displaced fromeach other a distance corresponding to one twentieth of the circumference of the g ar wheels when the parts are in the normal positions shown in Fig. 5 for performing additions and multiplications. The parts (33 and (3-1 which in the construction shown in Figs. 1
to 3 are provided for preventing axial distion with the revolutions counting mechanism,
comprising numeral wheels having two se ries of numbers displaced from each other, of two resetting mechanisms and the resetting members having ditferent end or zero positions and coupled with each other for operation in opposite directions and one of them operative only upon operation in one direction and the other one upon operation in the opposite direction, said resetting mem bers of both resetting mechanisms being so disposed relatively to each other that according to the direction of operation of the resetting mechanisms one or the other gets into end or zero position.
3. In a calculating machine. the combina tion with the revolutions counting mechanism, comprising numeral wheels having two series of numbers displaced from each other, and carrying mechanism controlled by said numeral wheels. of two resetting mechanisms having different end or zero positions and coupled with each other for operation in opposite directions and one of them operative only'npon operation in one direction and the other one upon operation in the opposite direction and both adapted when being operated to be set respectively in end or zero positions and to set the numeral wheels relatively to the carrying mechanism for operation thereof upon rotation of the numeral wheels in one or the other direction.
-l. In a calculating machine, the combination with the revolutions counting mechanism, comprising numeral wheels having two series of numbers displaced from each other, of two resetting mechanisms having different end or Zero positions and disposed one of them coaxially of the numeral wheels and the other one at the side thereof and coupled with each other for operation in opposite directions and one of them operative only upon operation in one direction and the other one upon operation in the opposite direction and both adapted when beingoperated to be set respectively in their end or zero positions.
