CALCULA'ING-MA CHINE I To :',ZZ whom, it 'may concern:
slidable pinion vof the machine Be it known that i, Cain. M". BERNEGA'U, a
citizen of the United States, residing at. Hoboken, in the county of .Hudson and State of New Jersey, have invented certain new and useful improvements in Calculating- Machines, 'of which the following is a speci-v fication.
This invention relates to a certain class of calculating machines, such, for. instance, as that forming the subject matter ot' United States patent to Alexander Rechnitzer, No. 809,075, dated January 2, 1906, and that forming the subject matter of French patent to Thomas, numbered 138,912 and dated Sept. 29, 1880, in which there are a series of drums or barrels actuated 4simultaneously by hand or power, through the medium of a shaft having a bevel gear engaging with a similar gear on the shaft of each drum. 1n the patented machines each drum has a series of nine teeth of graduated len th so that a pinion slidable on a parallel sha t may be located so as to engage with any number of the teeth of the drum during each revolution thereof to govern the extent of rotation of the shaft carrying the pinion. The slid-- able pinion is attached to a button pro`ect ing downward from the top or face o machine through a graduated slot, the position of the button andV consequently of the being indicated, on the top by a pointer on the button cooperating with the numbers (from 0 to 9) on the side of the graduated slot in said top. Thus, if a button indicator points to say the numeral 'Z at the sides of one of the graduated slots, the slidable pinion will be in osition to be engaged with seven of the teet of the drum below it, and the shaft carrying the slidable pinion will be rotated the distance of seven teeth during each complete rotation of the drum. -o
The shaft upon which the slidable'pinion is mounted is connected with and actuates the calculating mechanism so that the extentl of operation of the calculating mechanism is governed. by the position of the button in the graduated slot in the top of the machine, there being a drum, slidable gear, graduated slot, and button for each digit of the number being used in the operation of the machine;
In the practical operation of machines of this class, the slidable button arrangement has been found to be objectionable to some Specification of Letters Patent.
Application led November 27, 1906. Serial No. 345,398.
Patented March 24, 1908.
extent. ,lnsettin'g up a lnumber bymeans of these slides there is a liability to over-run,
or pass by, the proper number on the side. ot the graduated slot causing at timesecon#v siderable annoyance and loss of time in correctly setting the slide. At present it is particularly necessary to examine the posi' tion `ol'v'each slide after ithas been set in order to be sure that no accidental displacement has occurred. There is also a liability of the sleeve of the operator catching on such a 'slidable button without his knowledge in moving the hand and arni over the top of the machine, and thus unintentionallyset,
ting up a number where none is desired to be enumerated, or ol disarrangiiig a button already set and thus changing an item already enumerated in either case, the result being an operation upon a wrong number and a wrong'result. It is essential that all liability to such eiror be obi-'iatedin order that thel machine is reliable in result.
lt is the object ofthe present invention to remedy the defects now existing in machines of tlie class described and with this object in View I provide such machines with 'keyboards and keys instead of the graduated slots and sliding buttons.
This invention consists therefore in the improved construction,` arrangement and 'combination of parts hereinafter l'ully'described and afterwardsspecifically pointed.

This starting lever is the means employed to control the operations of addition, subtraction, multiplication and division as is fully explained in the Hnited States patent to Rechnitzer above referred to. The machine is also provided, as is eX- plained in that patent, 'with a. sliding carriage which carmes'the calculating mechanism. Theseparts form no part of my invention and are therefore not illustrated in the drawings. i
A shaft 11 (see Fig. 1) actuated from any. suitablesour'ce of power is supported in suit- It is provided with a number of beveled gears 13, 13, one gear c 'orres onding the key board andzeach cured to the shaft 11. i p
A series of drurns14, 14, (see Fig. 4) are' mounted on shafts 15,- 15, at pro er ,intervals along the machine, one drum ein' provided for each denominational series o keys on the-key board. -Each of said` shafts is. provided with..a beveledear 1,6 which. is adapted to engageI with. t e corres onding'ff gears. 13,. 13, on the shaft 11 whe eby the* drums 14, 14,. are continuousl `rotatedsp long as the shaftiis actuatedq heseg'drums 14, 14, are each provided with nine teeth, 17, 17, of progressivelyfincreasing length form. ing in eect muti ted ears (most clearlyl shown in Fig-,5), one vtoot 4correspondingon said drum to each of the digits 1n eachl de nominational series. The shaft 11 is adapt-4 ed to be continuously. rotated when vonce stlarteld until its necessary revolutionis comete p Mounted in convenient proximit -to thel mutilated gears, are numeral Wheel s afts 18, 18, (see Figs. 3 and 6) one foreach drum,l14, supported to rotate in suitable hearings 19 and 20 formed i the framework of the machine. Each shaft is made preferabl of prismatic, form along that ortion o its ength opposite the mutilate gear and between these bearings 19 and/20 and carries a slidable pinion 22 (best seen in Fig. 5) which is gear-beingrigidly seto fit over the prismatic section of the shaft and is adapted to slide freely thereon, but which by reason of the prismatic form ofthe shaft in the inion must, When rotated, communicate t e motion of the pinion to the shaft.

This spring serves to retract to position the spur gear after it has been rotated by means of the handle.
In order to simplify the description, I have shown but two of the denominational series of keys in the key board. These are, however suiiicient` to illustrate the construction and mode of operation of my invention. It Will ofcourse be understood that by increasing the number of denon'zinational series I corres ondingly increase the capacity of the mac ine, the other instrunieiitalities being made accordingly.
The numeral wheels of the Reclinitzer inachine are mountedibeneath the sliding carriage (not shown). They'jeoinprise wheels 70 mounted on a shaft 71 which also carries gear Wheels 72 connected hy trains of geen' ing 73 viith the kshaft 18 (liest shown in Fig. 6) andfit will be understood that the purpose of my invention: is, hy the4 depression of a key on the key board, to move the slidalle lpinion of its denominational series to such' a osition that the shaft l l, when rotated, shall, throughthe medium of the drum 14 and its gearing, give a proper number of turns to the shaft 18 to actuate the numeral u heels to a proper degree.
The operation of the mechanism above described is as follows: When it is desired to set up an item on't'he key board, the l'eys representing that item are depressed, one key in each denominational seriescorresponding This spurl gear has to the digits of the, item to he enumerated. b. lake, for instance, the denominational series of ke s show-n iii end elevation in Fio. l and suppose the key carrying the digit l and which projects furthest shove the top 10 of the machine is the one selected. 'lhe depression of thekey tip 51 moves downwardly the key stein and its footl55. This foot is thus brought into contact ith the upper suri face of the latch l ar 40 and'depressing the latter removes its lug 41 from contact with the upper meint` er 31 of the carrier 25. This carrier, under the influence` of the energy stored in the spring 26, moves toward the left as shown in Fig. 4, the aperture 33 perinitting the carrier to pass along the latch bai' I 40 until its upper meml er 31 comes into contact sith the ,side of the foot 55 of the key which has been depressed, `when, of course, it stops. This movement also brings the fingers 32 into position alove the toes .56 of the foot 55 and vprevents any upward movement of the key stem when the operator ceases to press dorme` ard upon the key tip.
The carrier, as has leen seen, has been brought toviest against the side of the depressed key stem and the parts are so ad`-, justed that the slidable-piiiion uhich has l'eeii moved vvith the carrier 25 v-:ill be lrought opposite the longest tooth on the drum 14. When the actuating lever of the machine is operated and the drum 14 is caused to be rotated, this tooth is brought I into' mesh sith-the pinion 22 and moves it andits shaft 1l one step, which step is of such a length that when the motionof the shaft 18 is,vthrough the gearing 73, coininuf .nicated to the numeral Wheel'70, the digit 1 on that wheel is moved to proper position vi ith respect to the other mechanism ofthe inachine in the same manner as though, in the Reclinitzer patented machine, its slidable button had heen moved along its slot to a position opposite the figure l and the parts had lz een )roperly actuated. `Assuming that the calcu ation desired then performed upon the machine and the operator wishes to rrestore the keys to their initial positions, the
handle 67 is, then rotated to cause the shaft 66 andcountershafts 63,63, to revolve. This movement actuates vthe restoring bar 60 in a rearward direction or to the right, when the parts are arranged as shovtn in Fig. 4 and as the bar comes into -contact Withthe lower projecting member 30 of the carrier 21' (and 'with all the either carriers and in'ions of the saine denominational series which havebeen similarly moved into positions in contact with the keysy of said series which have been depressed) it moves this pinion and. its carrier 25 hack to'their priginal positions charging the spring 26 with sufficient energy again to retract the carrier; when desired, and seating the luo 41 of the latch 40 against the carrier 25 under the inliiience of the spring 42.4 .Isf
one of the other keys, in the same series, had
lteen depressed, for instance, the one displaying the digit 9 and which is 'at the other end ofthe series from that carrying the digit l then the carrier would slide along its rod and through all of the passage ways 57 of thc keys which had not been' depress d, During such movement the lingers 32 pass Er-eneath the toes 56 of all oi the keyA stems until they reach the toes of the foot of the key 9 which had been depressed, when, of course, the ngers would be above such toes. The carrier thusmoves the slidable pinion Z2 to a position under the key 9 and this pinion would then be'o posite the shortest one of the teeth 17 on tlli)J drum 14. When the o erating lever of the machine is moved and t re drum 14 rotated, the teeth of the pinion are brought into mesh in turn with every tooth on the drum, namely, nine,- and would thus causethe numeral 9 to be set up on the numeral wheel at the proper position. The sl-idable pinion in such case is of course restored to its initial position by the actuation of the handle .67 as before.
It will be noted that after one keyrof any denominational series has been depressed and the pinion carrier has engaged therewith, the
. 'depression of anyv other key inthe same denolninational series has no effect on the digit sov set, unless and until the/,parts are all re stored te their initial positions.
