Specification of Letters Patent.

Patented July 21, 1908.

Application filed April 21, 1906. Serial No. 313,070.

BERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a specification.

This invention isconcerned with calculating machines including calculating typewriter attachments.

In a previous application filed August 25, 1905, Serial No. 275,780, I have shown a machine having a totalizer and means for devtermining whether at any given printing point the totalizer shall add, subtract or not 0 erate, in other words, a machine in which t e operator can decide beforehand whether, when the carriage is at'the right column, the totalizer shall operate ornot, and if so in which'direction. In that machine there are two master or settingwheels located opposite to (that is, in line with) each other, one for addition and the other for subtraction; and the totalizer passes between them and is capable of swinging into engagement with one or the other of them or occupying an intermediate position out of engagement with eitherof them. The present machine differs.

from theother in that althou h the master wheels are arranged in pairs, t e two-wheels of any pair are laterally offset so that the to talizer wheel can be in line with only one of them at atime and may also occupy a position between them, in which position no rotary motion'is transmitted to the totalizing wheels. In the same" respect this present machine differs from the one for which I filed application for Letters Patent Decemher 22, 1905, Serial No. 292,932.

The object of my presentinve'ntion is to produce the same final results as in the two aforesaidprevious inventions but without the necessity of moving either the totalizer'or the master wheels transversely to the direction'of travel of the totalizer or transversely to the axis of the rotation of the master wheel. i

' I attain my object by the mechanism illustrated in the accompanying drawings in which: I

, Like numera s denote like parts throughout the drawings.

In the typewriter, the stationary framework 1 supports a traveling carriagefl2 which has a step by step escapement under the action of the keys 3. A difierential or valuating mechanism 4 is provided for transmitting motionto the master wheels 5 and-6 and although the form of difierential mechanism is non essential, a suitable one is shown in Patent 782,554 granted to me Feb. 14, 1905. The-means of transmitting motion from the differential mechanism to the master wheel is also non essential but in the construction here shown said difierential mechanism operates the shaft 7 which is gear connected to each of the two master shafts 8 and 9, said shafts being journaled in the stationary brackets 10. Said transmission gearing is preferably mounted on the stationary platform 11. Shafts 8 and 9 are parallel with the direction of travel of the carriage 2 and the master wheels 5 and 6 respectively are rigidly fastened to them. Said master'shafts and master Wheels are so located and proportioned with reference to the accumulating wheels 27 of the totalizer that when an accumlating wheel is in line laterally with a master wheel the two will become enmeshed.

- .The totalizer travels in unison with the carriage but is transversely immovable. This is accomplished in the present design by the controlling device. Fig. 3 is a sectional mounting the totalizer upon a rectangular;

.- without engaging either of them. Fromwith the master wheels in traveling past them, are comparatively thin as are also said master wheels and that said master wheels when viewed from the front of the machine (Figs. 1 and 2) are laterally offset from each other so that a totalizer wheel 27 may occupy a position laterally beneath them this intermediate position a slight move ment .of the totalizer toward the right along bar 12 will bring the aforesaid accumulating wheel into mesh with one of the setting wheels, and a slight movement toward the left will bring said totalizer wheel into mesh with the companion master wheel on the other shaft. Shafts 8 and 9 rotate in opposite directions, and as they and their master wheels engage opposite sides of the totalizer wheels, the master wheel on one shaft will produce addition and on the other shaft will produce subtraction. Hence the totalizer will either remain at rest or or will add or subtract depending upon whether it stops with one of its wheels in an intermediate osition between two companion master w reels or at a point slightly to the left or to the right of such intermediate position.

The control of the position of the totalizer laterally uponits supporting bar 12 is effected by means of a controlling device which constitutes one of the features of this invention and will now be described: A bell crank mately horizontal arm 17 is pivoted to the arm 18 rigidly fastened to bar 12 or any other part moving in unison therewith. A link 19 connects the free end of arm 16 to the totalizer and the parts are so arranged that the vertical movement of the free end of arm 17 causes a slight shifting of the totalizer lengthwise-of bar 12, thisshifting however being sufiicient to bring an accumulating wheel 27 into line to mesh with. one or the other of a pair of master wheels or to a point between them. The vertical movement of the free end of arm 17 is accomplished by means of controlling pins 20 mounted in pin holders 21 on bracket 11, said pins being adapted to act upon any of the three cam surfaces 17*, 17 or 17 upon the underside of said arm. Said three cam surfaces17, 17 and 17 all have a different pitch with respect to the horizontal and they are so formed that when the totalizer is traveling from right to left, as in the normal action of the machine, the lowest cam surface 17 will shift the totalizer farthest along bar 12, the middle surface 17 will shift it a less distance and the surface 17 will shift it least or may be'designed, as I prefer, to shiftit not at all. Asa result when the top of a pin 20 contacts the bottom of surface 17 the totalizer will be shifted along bar 12 opposite to a master wheel, say for example one which subtracts, and when the top of pin 20 contacts. the bottom of surface 17 the totalizer will be shifted along bar 12 to a non acttive position with no totalizer whee, opposite to a master wheel; and when the top of pin 20 contacts surface 17 no shifting action of the totalizer along bar 12 will occur but said totalizer will remain fixed with reference to said bar, the totalizer in this position being opposite to the remaining one of a pair of master wheels, for exam le-the adding master wheel. The preferre construction is the one in which the surface 17 has zero pitch,

that is to say normally lies horizontal, for by this construction the totalizer may normally remain in say addition position upon bar 12 (addition being the commonest operation) and need be shifted only when it is desired that the totalizer shall remain non active or shall subtract; for it is obvious that by having the totalizer remain normally in adding position on bar 12, and shifting it along said bar only when subtraction or non action is desired, the surface 17 may be omitted entirely and only two cam surfaces be employed. in the present drawings 1 have shown only single acting cam surfaces instead of double ositive acting ones, which might be provided if desired, and for the purpose of cooperating with the single acting cams a spring 22 is provided for maintaining arms 17 in close contact with pins 20. in the structure shown this spring is a compression spring interposed between the totalizer and the arm 18.

An advantageous design of pin is the one shown in detail in Figs. 4, 5 and 6 in which the pin proper is formed upon the base 20 which is rectangular in horizontal cross sections and removably fits into pockets in a pin holder 21. The pin is formed eccentrically upon its base when viewed from one side and centrally when viewed transversely, from another side, with the result that by turning the pin around, that is, placing it in different positions in the pocket of the in holder, the pin will occupy a rearward, 'orward, or intermediate position to contact surface 17 as shown in Fig. 4 or 17 as shown in Fig. 4 or 17 as shown in Fig. 6 or 1 7 as sh own in Fig. 5. By this construction a single pin may serve by preadjustment to shift the totalizer along bar 12 to adding, subtracting or non acting position. A pin of similar construction is shown in the aforesaid previous application Serial No. 27 5,7 80filed August25, 1905, and is not here claimed. When a plutransmitted to the next highertotalizing rality of totalizersare tobe employed it is employed provided onlythat the wheels acted upon by the master wheels are capable of rotating in both directions, one for addition and the other for subtraction. In Figs. 7 to' 14 however a suitable totalizer is illustrated in detail, the construction being identical with that shown in Patent No. 782,605 issued to me Feb. 14, 1905. In this totalizer, .23 represents the totalizer shaft which is non rotatably mounted in the totalizer casing 24. Upon this shaft are supported a plurality of sets or groups consisting of five principal parts, to wit: The totalizing Wheels25, thecarrying pinions 26, the accumulating wheels 27, the epicyclic pinions 28, and the intermediate wheels 29. Wheels 25, 27 and 29 are all freely rotatable about shaft23 with the exception of wheel 29 located at the extreme right to correspond with the units column. This wheel is rigid on a shaft and its function is to form a fixed basis or foundation from which the rotatable parts'of the totalizer move their definite amounts.

In each group of parts 30 represents a disk like supporting piece which is splined'to the shaft and has at its left portion a cylindrical hub 30 which forms a bearing whereon the intermediate wheel 29 is freely rotatable. The pin 31 extends toward the left *from piece 30 and serves as an axle whereon the carrying pinion 26 is freely rotatable. Said carrying pinion has four long and four short teeth which alternate with each other as best shown in Fig. 8. By means of the long teeth said carrying pinion is alternately locked and rotated by the locking ring 25 and carrying teeth 25 respectively of the totalizing wheel 25 at its right. The short teeth serve to make the left portion of the carrying pinion a complete eight toothed gear, and this left portion of the carrying pinion remains permanently in gear action with the internal gear portion 25 of the next totalizing wheel to the left, by means of the gears 27, 28 and 29 as hereinafter described. As the result the carrying action of pinion 26 is always wheel 25. Each totalizing wheel 25 has a set of numerical figures on its exterior cylindrical surface and is supported by the contact of its internal cylindrical surface 25 (which constitutes the aforesaid locking ring) upon the cylindrical edge of the supporting disk 30, said wheels 25 bearing loosely upon their supporting disks so as to be freely rotatable independently thereof.

The accumulating wheels 27 are plain spur gears having a comparatively large central I aperture so that they may set over and be freely rotatable upon the oints of the teeth of the intermediate whee s 29. Said accumulating wheels are narrow and their teeth project beyond the circumference of totalizing wheels 25, so that they may be engaged by the master wheels '5 and 6. The totalizing wheel 25 and supporting piece 30 (shown at the extreme. left of Fig. 7) are slightly modified to impart a finished appearance to the extreme left end of the totalizer.

Extending leftward from each accumulating wheel 27 are two pins 27 which constitute axles whereon the epicyclic pinions 28 i carrying pinion 26 and epicyclic pinion 28 at the left and serve to transmit the carrying action ofthe carrying wheel to the epicyelic pinion and thence to the next higher totalizing wheel 25. 'As a result of the above described construction of the totalizer it follows that the accumulating wheels 27 are rotatable in either direction and when rotated in one direction will add and when rotated in the opposite direction'will subtract.-

Tn operation, the typewriter carriage 2 and hence the totalizer, travels from right to left when viewed from the front of the machine as in Fig. 1, and the traveling is intermittent, that is to say, the carriage and totalizer travel step by step having a rest point or station at the end of every full step as is the case with the most common form of typewriters now in use. 1 As above ointed out, the condition as to whether t e totalizer shall add, subtract or not operate'depends upon the adjusted position of the totalizer in 1 each rest station thereof; therefore the operatorso adjusts the pin 20 in holder 21 that it will contact the proper surface upon the cam arm 17 to shift the totalizer to the proper portion of the rest position. In the resent construction if it be considered that t e rear shaft 9 is the subtracting shaft and the forits complish'by adjustin the pin to the position shown'in Fig. 6 in w ich the top of the pin will contact the lowest surface 17 of cam arm 17.. If he desires the machine to add he will adjust pin 20 to the position shown in Fig. 4, endif he desires the totalizer to remain still he will adjust the pin to occupy an intermediate position as shown in Fig. 5. If there are more than one pair of master wheels as is the case in the machine illustrated, the operator willinsert in the holder a pin for each pair of master wheels, and as each pin is independently adjustable the totalizer may be made to add at one pair of master wheels subtract at another pair and remain still at another pair or the order may be varied at the will of the operator. If a plurality of totalizers are employed as illustrated in the drawings, a corresponding number of pin holders will be employed and as these pin holders are out of line with each other and the pins in all of them are independently adjustable, each totalizer may be made to operate independently of every other totalizer, and one may be made to add at a point where its predecessor subtracted and vice versa.
