This invention relates'A to improvements in calculating machines.' f y -In certain arithm tical calculations, it 'is neces-sa to utilize va-formula comprising a e, series o digit' and zero values. For instance, the numeral required to be multiplied by a series of multipliers, such, for instance, as plus one, :minus one, zero, and so forth. -The l@ formula is standard and the sequence of numbers constituting the multipliers remains constant in the same series. -f
" The calculations may also comprise the multiplication of one number simultaneously T lby'aseries of numbers constituting separate v formulae.v v
An object'of the present invention, therefore', is to rovide a calculating device where by throng adding and substracting opera- 2@ tions, a series of products may be obtained and totaled, using a selected number for the multiplicand and the formula series of num-.
bers as the multipliers.
With the foregoing, aswell as other dew tailed advantages in view,-the construction hereinafter disclosed has been designed, reference being made tor-the accompanying drawing in wh1ch, Fig. 1 is a plan view of the mechanism; mand g Fig. 2 is an end elevation. ln the embodiment 'of the invention illus trated lin the drawing, the device is shown as oi intermeshing gear wheels wheels being fixed to the shafts 3 and 4. Each of the gear wheels l and 2 has a hub 5 and 6 respectively, said hubs having rigidly attached vvthereto one member of a cou ling device 7 and 8 respec- Ihe wheels lor 2, and in the embodiment shown,jthe Wheell 2, is opera,- tively connected with a key 9 having a pawl 10 at its inner end and a linger piece 11 at its outer end, said hey being pivoted on a 'The arran ement of the pawl is such that upon the epression of the key,
the wheel 2 will be rotated in the directionv of t e arrow, Fig. 2, one tooth distance for 'each depression of the key.. Obviously, the
5@ operation of the gear vwheel '2 imparts a.
reverse rotation to the gear wheel l.
` The result of the separate calculations is accmulated in separateV series of jaccu-I mounted in housingsthe shafts. 3 and' uinlating wheels 13, @il disposed longitudinally of 4numbers having a plus and minus- 4 and preferably placed between the shafts. Insomuch as the accumulating wheels constitute recognized accumulating mechanism, the details of the accumulating roup will be understood without specific escription. Each group of accumulator-s is actuated by a wheel 14 disposed at one end. ofthe group, said wheel 14 being operatively connected with theshafts 3 and 4 by mechanism about to be described. v
As each ofthe group of accumulators of duplicate construction, and as the operative connections vbetween the accumulators and the shafts 3 and 4 are similar, it will be understood that the explanation ofone group will apply to the series of accumula- :tors and their connections that may be in corporated in the machine, it being understood that the number of accumulatore may be any predetermined or desired number.
The connectionsbetween the shafts 3 and 4 with the actuating wheel 14 of the accumulater groups comprise wheels -15 and 16' respectively loosely mounted r,upon the shafts 3 and 4. Each of the wheels 15. and 16 is 'formed with a recess 17 adapted to engage with alug 18 of the coupling devices 7 and 8. The wheels-15 and 16, as Well as the accumulator actuators 14, are formed with 4smooth' peripheries so that by rictional con- `tact, the wheel 14 `may be moved alternatively in one or the other direction, according to its relationship with the wheels 15 and 16. In order to alternately and selectively couple the wheels 15 and 16 for rotation by the 'shafts 3 and 4 respectively, the said wheels 15 and 16 are connected with opposite endsl of a lever 19 pivoted at 20 by links 21 and 22.
By reference to Fig. 1 of the drawing, it will be noted that the upper group oi connections illustrate the wheel 15 as operatively connected with the shaft 3. The lower group of connections illustrate the couplings in neutral position where-both the wheelsl and 16 idle onthe shafts 3 and4.
The selective "devices for determining the ultimate direction of rotation of the actu-4 ator member 14 of the accumulator group comprise plates having predetermined con- 'i'i uration of cams on their marginal edges. Tie cams for each group', while diierent in formation, operate upon the same principle and may be conveniently described together.
Each of the cam lates 23 is revolubly mounted on a lstud s aft 24,'said .shaft 24 11G l of the shafts 1 and 2. The cams are operathe intermediate position illustrated in thc` l'ao accumulators.
tively connected with one end of the lever 19 by an extension 25 ofthe link 22. The free end of the link 22 carries a cam roller 26 that operates against the cam face ofthe plate 23. The cam face of the plate 23 is arranged to actuate the lever 19 so that the lever will assume three distinct positions, the one as illustrated in the upper part of Fig. 1, in which the Wheel 15 is opleratively connected with the shaft 3, the ot er being lower group of accumulator connections in Fig. 1, and the third position in which the wheel 16 is operatively connected with the shaft 4. Thus, the cams determine a plus or minus operation of the accumulator group and also a neutral position in which the key may be actuated without influencing the The lever 19 is actuated by an expansion spring 27, the normal tendency of which is to depress the arm of the lever vremote :from the cam actuator, it being 0b-` vious that when the roller 26 rides'upon a high point of the cam, the arm of the lever 19 adjacent to the cam will be depressed, thereby coupling the wheel 16 with the shaft 4. When the roller 26 rides upon an intermediate point of the cam, the coupling device will be in the intermediate position shown at the lower part of Fig. 1, and likewise when the roller 26 rides against a low part of the cam, the wheel 15 will be coupled with the shaft 3.
Each of the plates is formed with double contact surfaces so that the complementary value on one face of the cam is provided or. the other face of the cam. That is to Say, for a corresponding high point on the upper part of the cam, there is a complemetary low part on the under part of the cam. This arrangement is to provide for adjusting the result of a multiplication to correspond with the plus or minus values of the multiplier and the multiplicand. The cam late 23 is therefore carried on asupport 2 that imarts an axial movement to the cam. It will be noted in Fig. 2 that the periphery of the cam disk is formed with an offset 'face so that for each high point there is a complementary low point located in the lower horizontal plane.
When it is desired to give a reverse value to the product, the support 24 is moved upwardly to bring the cam Wheel 26 into contact with the complementary face of the cam disk. The longitudinal movement of the support 27 may be imparted by any suitable mechanism, for instance, by an eccentric device 28 operable by means of a key extending exteriorly of the frame of the machine.
The/rotation of the cam disks 23 is accomplished in unison by means of pawl and ratchet devices 29 pivoted at 30 to a bar 31,
et device are spaced so as to rotate the cam disks predetermined intervals upon each operation of the handle 32 so as tc bring in rotation the desired cam surfaces with the cam w'heel26.l
From the foregoing, it will be understood that the operation of the device is as follows: -F or example, selecting the numbers plus into contact one and minus one as themulti licand and i multiplier respectively, the mu tiplier will be represented inaccordance with its value The product 0f the plus and minus values will be a minus product. Theref0re,vthe
rection of rotation to the actuator of the accumulator 14 representing a minus product of one.
Similarly utilizing plus one as a multiplicand and plus one as a multiplier, the multiplier plus value will be represented by the high point of the cam disk actuating the coupling device, so that the shaft 4 lis o eratively connected with the wheel 16. T erefore, upon the depression of the key, a plus product will be set up inthe actuator 14 of the accumulator group. If a negative value is multiplied b a negative value, the cam will be adjuste to bring the complementar face thereof into contact with the cam whee reversing the normal position of the coupling devices and re resenting a plus product. In any multip ication of zero, either in the multiplier or in thel multiplicand, the coupling devices assume a. neutra1 position and there will be no accumulation in the accumulator. v
It is thus seen that the device provides means for selectively representing series of plus, minus and zero values of the multiplier in predetermined sequence corresponding to the formation of the cam faces.
I am aware that the invention may be modified in many particulars and that the principles thereof may be embodied in widely varying structures.
I do not limit myself, therefore, to the construction shown and described; but what I claim and desire to secure by Letters Patent4 los lio
