FRANZ DRINKS, OF BRUNSWICK, GERMANY.
CALCULATING MACHINE.
Application filed November 9, 1921 Serial No. 514,078.
T all whom it man concern:
Be it known that I, FRANZ THINKS, residing at Brunswick, Germany, have invented certain new and useful Improvements in Calculating Machines, of which the followin is a specification.
y invention relates to improvements 1n calculating machines, and more particularl in calculating machines of the type in whic a setting mechanism cooperates with two registering mechanisms, and in which in addition a revolutions counting mechanism is provided. By means of machines of this type multiplications can be performed in which the number of the figures of the result exceeds that of the numeral wheels of each registering mechanism. The object of the improvements is to provide a machine of this class in which at the end of the calculation the multiplier is correctly displayed b the revolutions counting mechanism. Va ith this and other objects in view my invention consists in the matters to be described hereinafter and particularly pointed out in the appended claims.
For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing, in which the same letters of reference have been used in all the views to indicate corresponding parts. In said drawing,
Fig. 1, is a front view of apart of the calculating machine,
Fi 2, is a vertical crom-section taken on the line 2-2 of Fig. 1 showing the main revolutions counting mechanism and subsidiary revolutions counting mechanism forming a part of the mam revolutions counting mechanism, and
Fig. 3 is a sectional elevation of the calculating machine showing the setting mechanism, the registering mechanisms, and the main and subsidiary revolutions counting mechanism.
In order that my invention be clearly understood I shall at first describe the method now in use for performing a multiplication in which the number of the figures of the product exceeds that of the numeral wheels of each registering mechanism, reference being made to a calculatin machine of the construction shown and escribed in the tent of the United States No. 705,838 to amann, granted July 29, 1902. A machine of this construction has been shown in Fig. 3 of the accompanying drawings, and
in addition the parts forming the subject matter of my invention have been shown as embodied in the said machine.
Referring at first to the-old parts of the said calculating machine, the setting mechanism p consists of a rotary shaft 8 carryin setting wheels 1 each containing nine test 2 any number of which may be shifted outwardly by cam disks'3 provided one for each wheel. The setting wheels are adapted to be rotated from a machine crank 6 through the intermediary of gears 4: and 5. In front of the setting mechanism there is a registering mechanism g adapted to be operated by the setting mechanism through the intermediary of a gear wheel 7, as is known in the art. Below the registering mechanism q there is a second registering mechanism 1' ada ted to be coupled with the registering mec anism g by intermediate. gear wheels 8 provided one for each of the numeral wheels of the registering mechanisms q and 1'. The gear wheels 8 are, rotatably mounted on a shaft 8 supported on arms 1" havingrocking supports on the shaft 1' carryin the numeral wheels of the registering mec anism r, and they are adapted to be thrown into or out of engagement with the gear wheels of the reglstering mechanism g by rocking the arms'r and the shaft a mounted thereon by means of a bell crank lever t. Both registermg mechanisms 9 and r are mounted on a carriage 0 adapted to be shifted relatively to the setting mechanism 72 in a direction parallel to the axis thereof.
Above the setting mechanism there is a revolutions counting mechanism d the numeral wheels of which are connected each with a gear wheel 2'. The revolutions counting mechanism (.1 is adapted to be rotated from the machine crank 6 through the intermediary of a ]gear wheel 5 engaging in a gear wheel 11 eyed to a shaft 12. On the said shaft a single tooth wheel 13 is longitudinally shiftable, which is connected with the carriage o by an arm 14.' Upon each revolution of the machine crank 6 the single tooth wheel advances one of the gear wheels 15 and the gear wheel 1' meshing therewith a distance corresponding to one value.
The parts so far described are known in the art. In order to perform a multiplication the intermediate gear wheels 8 are rocked into engagement with the gear wheels of the registering mechanism 9, and the multiplication is carried out by means of the setting mechanism p both registering mechanisms g and r, until the capacity of the registering mechanisms is exhausted, which is indicatetd by a bell or the like. In the course of this calculation the carria o is successivel shifted to the right acco ing to the num er of the figures of the multiplier. Now the carriage o is returned nto initial position, so that the intermediate gear wheel 7 located at the right of the set of intermediate gear wheels is in position for cooperation with the first setting wheel 1. The intermediate gear wheels 8 are rocked out of engagement with the gear wheels of the registering mechanism 9, the registering mechanism q is reset, and from the figures displayed hiv the re stering mechanism 1' those ocate at the le t of the single tooth wheel, before the carriage 0 was shifted, are carried over to the right hand numeral wheels of the registering mechanism g, which is done for example by hand after opening the top plate of the machine, or which may be done by setting the said number on the setting mechanism 12 and once operating the machine crank 6. Now the multiplication is completed by means of the multiplicand set in the setting mechanism and the remaining figures of the multiplier, and the partial result thus obtained in the registerin mechanism 9 is added to the partial resu t of the first calculat on which is still displayed by the registering mechanisrn'g.
Example: By means of a calculating machine .having two registering mechanisms 1% and 1* each comprising ten numeral whee the mutiplication is to be performed.
The number 3232323 is first set on the setting mechanian and multiplied four times by 2 while successively shiftin the carriage o carryin the registerin mec anisms q and r. There y the number 182221706 is transmitted to the registering mechanism. Now
the carriage 0 is shifted to the left and into initial position, the frame 1'' is rocked downwardly with the gear wheels 0 out of engagement with the gear wheels of the registering mechanism q and the registering mechanism g is reset. As the carriage has been shifted to the fourth place and back again the last four fi res of the partial result have been determined. Accordingly the remaining figures 718222 are now transmitted to the second registering mechanism, whereupon the carriage carrying the registering mechanisms is again set in o rative position and the calculation is continued in the usual way by multiplying the number 3232323 by 22. Now the second re istering mechanism di' lays the number %1829328 which is combined with the number 1706 left onthe first registering mechanism into the final result 718,293,281,706.
When thus performing the calculation the revolutions counting mechanism does not display the correct multiplier 222222 but the number 2244. The object of the improvements is to avoid this error. For this reason I provide an indicating mechanism or subsidiary revolutions counting mechanism cooperating with the main revolutions counting mechanism and taking part in the movement thereof, which indicating mechanism is adapted to be rocked out of operative position at the end of the first partial calculation for preserving the partial multiplier (2222), so that after resetting the main revolutions counting mechanism the second part (22) of the multiplier can be displayed thereby. The tru multiplier is obtained by combining both partial multipliers (2222; 22:222222).
In the example shown in the figures the indicating mechanism consists of a set of gear wheels a and numeral wheels 1) con nected therewith, said wheels being loosely mounted on a shaft h secured to rock arms 0. The numeral wheels I) are adapted to be rotated from the gear wheels 2' of the revolutions counting mechanism d throu h the intermedia of gear wheels 6, an they are adapt to be thrown out of operation by locking the rock aims c and the indicating mechanism mounted thereon away from the gear wheels e. To the rock arms a noses m are secured which are adapted to engage in either one of a pair of notches (7 provided one in each of spring p locking pawls f for securing the indicating mechanism in operative and inoperative sitions. The revolutions countin mec anism d and the indicating mechanism 12 are equipped with resetting means of any known or preferred construction represented in Fig. 1 by wing nuts k and Z.
In the preferred construction shown in the figures the resetting mechanism In of the main revolutions counting mechanism d is equipped with a cam n cooperating with the subsidiary revolutions counting mechanism 6 through suitable 'ng for rockingthe same into inoperative position when resetting the main revolutions counting mechanism. The subsidiary revolutions counting mechanism is rocked into 0 rative position by hand, for example b epressing the rock arms 0 by means 0 the wing nuts Z.
The revolutions counting mechanism and the indicating mechanism are used as follows: When performi the first partial multiplication both mec anisms are in operative positions, the revolutions counting mechanism d being rotated from the machine crank 6 and transmitting such rotation to the indicating mechanism b through the intermediary of the gears a. At the end of the partial mu tiplication both mechanisms show the number 2222. Now the revolutions counting mechanism. d is reset, and the indicating mechanism 6 is rocked by the cam n out of engagement with the intermediate ar wheels e, whereupon the second artlal multiplication is performed by whic the number 22 is transmitted to the revolutions counting mecha nism (1. Finally the parts of the multiplier are combined (22, 2222:222222). Before starting a new calculation both mechanisms are reset.

In a calculating machine, the combination, with the setting mechanism, and two registering mechanisms movable relatively to the setting mechanism, of main revolutions counting mechanism, and subsidiary revolutions ccunti mechanism adapted to be thrown out o relation for operation by the setting mechanism.
