SPECIFICATION forming part of Letters Patent No. 781,368, dated January 31, 1905.

Application iiled August 3l, 1904. Serial No. 222,871.

To (MZ 'mil/om, '/t 177151,17/ concern,.-

Be it known that I, GEORGE E. SenUMAN, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Calculating-Machines; and 1 hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in calculating-machines, and comprises novel mechanism for actuatingthe registering-wheels, novel mechanism for carrying over from a wheel of lower to a wheel of higher denomination, novel mechanism for resetting the numeraldisk to zero position, novel mechanism for printing' the items as they are registered, and novel mechanism for printing the totals that have been attained by themachine.

The invention also comprises other novel details of construction and combination of parts, and I will refer to the following description of the machine illustrated in the drawings for detailed explanation thereof and to the claims following such description for a summary of the parts and features for which protection is desired.

'ln the drawings, Eigure l is a vertical longitudinal section through the complete machine. Eig. 2 is a detail section in the same plane as and beside that of Fig. l, but looking in the opposite direction. Fig. 8 is an enlarged horizontal sectional plan view. Eig. t is an exterior side elevation. Fig. 5 is a detail section showing' the opposite inner side of the machine. Fig. 6 is a detail sectional view showing the arrangement of the typehammers. Fig. 7 is a detail section, enlarged, on line 7 7, Fig. 4. Eig. 8 is a detail part section and part plan view showing parts in position for the totaling operation. Eig. 9 is a sectional detail showing a modification of the keyboard. Eig. lO is an enlarged plan of the carry-over and braking devices. Fig. 1l is a side view of Fig. 10. Fig. l2 is a detail view showing one of the notched and numbered Y guide-slots for the adding-levers, and Eig. 13

is a detail view of the key-bar and lever.

the registering-wheels B, of which three are shown respectively, units, tens, and hundredsearranged from right to left. Of course any number of these wheels may be used as is desired, so that the capacity of the machine is practically unlimited, enough wheels being shown, however, to clearly illustrate the invention.

Each wheel preferably contains a multiple of ten teeth. ln the example shown each wheel has sixty teeth, and consequently for each sixth rotation of the wheel ten will be counted and at each sixth of a rotation of a registering-wheel of lower denomination a wheel of higher denomination will be advanced one tooth, as hereinafter explained.

Pivoted on the shaft A. beside each wheel B is an oscillating' lever C, which is normally retracted by means of a spring C', and attached to and beside the upper arm of said lever is a vertically-movable bar c, the lower end of which is slotted around the shaft A, so that it can be guided thereby, and the bar c has a pin c engaging a guiding-slot Cv2 in the upper part of lever C, as shown, the part c forming practically an extensible portion of the lever U and projects through aguide-slot d in the top of the casing D of the machine. This slot l is of such length that the movement of the lever through the slot would sutiice to impart one-sixth of a revolution tothe wheel B. On the side of this slot (l are eleven notches d, between which are the beveled lugs (Z2, which are adapted to direct the lug on the side of the bar c into the desired notch. The bar c is provided with a linger-piece c, by which it can handled, and it may be brought over the desired notch and then depressed, so as to force lug c2 into a desired notch d. The object of having the part c depressible is to accomplish the printing before the shifting of the registering-wheel or lever occurs, the printing' mechanism being brought into proper position by the radial movement of the lever C and the printing operation effected by depression ofthe bar c, as hereinafter explained.

The notches d may be numbered, respectively,from O to 9, followed by a 0, the numbers extending from front to rear in the On the main shaft A are pivotally mounted i ordernai'ned, (see Eig. 12,) and it will be under- TOO stood that by positioning the lever opposite the desired number before depressing it the amount to be registered on any given wheel is determined. The rearmost "0 position is used for a purpose hereinafter explained.

The wheels B are kept from momentum movement' and also properly positioned by means of the beveled-tootli dog b, loosely mounted on a shaft W, suitably journal'ed in the casing and adapted to engage projecting 4pins B on the sides of the registering-wheels B, as shown in the drawings, (see Eig. I.) the dogs being pressed against the pins by springs b2, as shown. The lower end of lever C is bent rearwardly, as indicated at C3 in the drawings, and depends below the wheels B, and to it is pivotally attached an arc-shape type-carrier C4, which may be of any suitable construction, but is preferably constructed as follows: To the under side of this type-carrier is attached a rubber type-band C5, having on its lower face a series of numbers, O to 9, inclusive, followed by 0. Above each numeral of the band and passing through an aperture in the carrier C* is a push-button C, which is adapted to be struck by a hammer E on the end of a lever E', which is pivoted on a shaft E2 in the casing and is provided with a short depending arm E3, acted upon by a spring Ef, so as to normally hold the hammer E in uplifted position, as shown in full lines, Fig. l. This hammer may be forcibly depressed at the proper time so as to strike the push-button thereunder by the following means: A dog e is pivoted on the lower end of an arm e of a bent lever pivoted on a shaft @2, jourualed above the shaft E2. This lever e has a horizontally inwardly projecting arm @3, which projects inwardly under the shaft A and close to and beneath the lower end of the bar c of the related registering-wheel B, so that when bar c is pushed downward it engages lever @3 and depresses the latter, swinging arm c outward and causing doge tomengage arm E3 of the lever E' and throw the hammer E forcibly down against the push-button C thereunder, which push-button projects the type on the rubber band through an opening D/ in the bottom of the casing against a web of paper W, which is fed thereunder, thereby imprinting the proper numeral on said web.

The type may be inked in any desired manner. I have merely indicated two inkingrollers C7 in the drawings on opposite sides of the opening D. These rollers may be supplied with ink in any desired manner.

The dog e is pressed upwardly against a stop @"1 by means of a spring c5, as shown, and this dog has a depending' lug e, which is adapted to strike astop in the bottom of the casing after it has completed the downstroke of the hammer E, which stop causes the dog to oscillate on its pivot and pass below the arm E3 of the lever E', which is then immediately swung back so as to raise the hammer outof the way by means of the spring E", as shown. The dog can return to its normal position under the arm E and resume its operative position.

It will be noted that the proper type is brought into position over the opening D' before the bar c is depressed and that the depression of this bar accomplishes thc printing as described.

Immediately following' the printing a pin cAL on bar c engages one of the notches of the registering-wheel, and then by pulling the arm and lever forward the registering-wheel is turned the desired number of teeth. Upon the release of the pressure on the bar c the lever is thrown back to normal position by the spring C', and the bar c is thrown upward into normal position by means of a spring c, conneeted'to the upper bar and the lever C, as indicated in the drawings. The paper web `W, as shown in Eig. l, may be led in from a reel w at one end of the machine,

y passed under the opening D@ and wound upon take-u p reel w' at the rear end of the machine. On the shaft of roll w is aratchet af, (see Eig. 4,) engaged by a pawl fr on the short arm of a lever m2, the long arm of which extendsforward and is adapted to be engaged by a pin f on a vertically-movable bar E, Fig. 7,

which has a button E on its upper end, by which it can be depressed, and when this bar E is depressed the pawl is moved back to engage a new tooth of the ratchet, and when the bar is raised a spring .013 throws the lever forward and causes the dog to return the ratchet m one tooth. On the roll fw is a ratchet X, which is engaged by a dog X/ on an arm X2 of a reciprocating bar X3, which is pivoted at its forward end to the lower end of a bell-crank lever X4, the other arm of which projects intothe path of the pinf, so as to be operated after the lever 11; has been depressed. The lever X'l is retracted by a spring X".

In some instances it may be desirable to have the machine move laterally over the surface upon which the record is to be printed4 as, for instance, if tabulating in a book. For this purpose the machine can be moved over the base-plate D, as indicated in the drawings. Attached to this base-plate at each side of the machine is a ratcheted bar Y, (see Eig. 4,) which is adapted to be engaged by a pawl y, pivoted to the lowerend of a link y', pivotally attached to the side of the machine-casing, and said link fz/ is also pivotally connected to the bar X, so that when the lever X" is oscillated by the depression of the bar E, as above described, the pawls will be advanced one notch over the ratchet Y, and then when the lever is released the spring X"l will cause the machine to move forward one notch.

The button E may be attached to the bar F, so that it may be moved laterally there- IOO I'IO

with; but it is normally held by a spring F2 and traverses the slot F3 in the side of the casing. The lower end of this slot is enlarged, so that when the bar has been fully depressed the button F/ may be pushed inward, causing its stem F* to engage and reposition the carryover wheels, as hereinafter explained.

The @Mr z/-o/Uer dwt'ccaBeside and meshing with each registering-wheel is a small tentooth pinion G, loosely journaled on the shaft G/ and mounted in the casing. These pinions G are made quite wide for a purpose hereinafter explained, and they are rigidly connected to a numeral-disk G2, which lies opposite sight-opening D3 in the casing. (See Figs. l, 8, 10, and 11.) Attached to the gear G and numeral-disk G2 of the "tens-wheel and the wheels of higher denomination is the small ten-tooth pinion G3, which is adapted to be engaged by a pawl g on a registering-wh eel of lower denomination whenever the latter moves ten teeth. In the construction shown each registering-disk has six such pawls, (see Fig. 2,) as it has sixty teeth. The pawls g are thrown outwardly into position to engage the gear G3 by spring g and are limited in their upward movement by stop-pins g2, as shown. These pins at the moment the dog engages the gear G3 contact with pins /L on a rock-shaft L, to which is attached an arm lf, that projects over the series of pins B on the registering-wheel B, which is actuated bythe gear G3, and has a tooth /t3 which the moment.

the gear g3 causes such disk to move one notch enters between pins Bl and locks the wheel, thus preventing any momentum movement of the registering-wheels during the carry-over operation. As shown in the drawings, there is no gear G3 for the units registering-wheel, as there is nothing to carry over to said units registering-wheel. The latter, however, operates the gear g3 for the tens registering-wheel, and the latter registeringwheel operates the gear g3 for the hundreds registering-wheel, and so on, according to the number of registering-wheels employed. The stops 7a2 are so timed as to act the moment after the dog begins to turn the pinion G3 and are thr-own out of position the instant the pawl has turned the pinion one tooth and are normally held out of position to engage the pins B by means of a spring on shaft It.

The total/fag devices-If it be desired at any time to print the total of amounts which is registered on the machine, the mechanism and operation is as follows, (see Figs. 3, 5, and 8:) Pivoted on the shaft A at one side of the machine is a disk I, from which projects a radial arm I', carrying a horizontal bar l2, which lies in rear of all the levers (l and above the registering-wheels. To this disk I is pivoted a lever t', which is normally pressed outward by a spring and has attached to it a button i, the shank of which plays through a guide-slot if, this slot being curve-d on an arc concentric to the shaft A and having enlargements 1' at its ends to permit the button to enter and to recede from the casing. The normal position of these parts are` as indicated in Fig. I, with the bar I2 out of the way of the levers and the button 3 projected out of the casing through the enlargement at the upper or rear end of the slot. By grasping this button and pulling it forward bar i engages the several levers Gand swings them forward, but does not impart any rotary motion to the registering-wheels B, as pins cL are not engaged therewith. IVhen the button 3 is pulled to the forward part of the slot, it is pushed inward, as indicated in Fig. 8, and engages a pin or collar G" on the shaft G', carryingthe carry-over gears and numeral-disks, and this shaft G is moved laterally with these devices, so as to cause gears Gto move laterally out of engagement with the respective registering-wheels B and into engagement with segments B5, which are attached to the levers C and have teeth coincident with the teeth of the related wheels B. The button 3 is then released, whereupon the springs controlling the levers C throw them backward, and the segments B5, then meshing with the gears G, rotate the latter and the connected numeral-disks backward until the numeraldisks are arrested by engagement of pins G" on their peripherics with stops y' on a bar J, secured in the casing, the stops being so positioned relative to the numeral-disks that they are out of the way ofthe pins GL when the gears G3 are in engagement with the registeringwheels, but are in the path of the pins G4 when the registering-wheels and numeral-disks are moved to the right, as above described. When the pins GL strike the stops 1', they arrest the movement of the segments in mesh therewith, and consequently of the levers C, and this stops the printii'ig-plates with the numerals corresponding to the numerals which had appeared at the sight-opening in printing position. The operator then depresses bar F by means ofthe button F', and the pin f on the bar F as it reaches the lower end of its stroke strikes an arm or rod c, projecting from the shaft @2, and operates the latter in precisely the saine manner that the bar c would have done through the lever c3, and this causes the several hammers E to descend and make an impression from the proper type upon the paper through the openingD, thus printing the total. rlhe object of the second or rearmost naught or cipher above referred to is as follows: This cipher is printed when LO appears in any item by simply pressing down the related key baror lever as the corresponding "0 on the related type-bar is in position to print when the key-lever is in normal retracted position. In printing the total,how-

ever, the keys are all brought forward first, and the levers that are to print ciphers are l held in the forward position until the print- IOO IIO

ing is effected, because the pins Gien the corresponding numeral-disks prevent the return of the levers. H ence the second naughts must be used on the type-carrier to obtain the correct printing action. After the bar Fis fully depressed the button F' is pushed inward, whereupon its stem FG engages an arm G5 on the shaft G and pushes the latter back to original position, disengaging the gears Gr from the segments B5 and moving' them into engagement with the respective registeringwheels, as at first. The segments B5 are located close to their relative registering-wheels, and the gears G are made wide enough to engage a segment before disengaging the gear, and vice versa.

Regent/.ing Zanica-In order to reset the registering-wheels so that the numeral-disk will show Zero at the sight-opening D3, the following device is employed, (see Fig. 2:) A bail K is hung on the shaft A and extends across and below the registering-wheels, and this bail carries a rock-shaft 1, to which is connected a series of projecting pins k', that are so located as to engage with any superimposed pins g2 on the adjacent registering-wheels B when the bail is swung upward. rlhe pins 71.1 are held in normal position relative to the bail by means of springs Il?, which will allow the pins to go backward, but holds them normally in position to engage the pins g2 if the bail is swung upward. The bail is limited in its motions by a stop K' below and a second stop K2 above, the extent of motion of the bail being in the example shown about sixty degrees. The bail may be lifted when desired by means of a pull-rod it, which extends to the outer side of the casing into convenient position to be reached by the operators hand. W hen the bail is lifted, the pins 7'/ will engage the pins gli, as stated, and will turn the registering-disks and the engaged numeral-disks until the latter stop at the Zero-point. The inner ends of the pins move in an arc concentric with the axis A, and consequently will engage any pin which happens to be between the extreme positions of the bail.

' In Fig. 9 I have illustrated a modification in which the extent of movement of each lever C is determined by individual linger-keys, cach properly numbered, so that the operator has simply to depress the properly-numbered key and move the lever therewith instead of having to gage the movement of the lever by numbered slots. In this construction the lever C and bar c are substituted by a lever C, which is guided bythe shaft A and can play longitudinally by reason of a slot o around the shaft. This lever carries a spring-actuated pawl C7, engaging' the registering-wheel B and having a slot and pin connecting with the lever, so as to allow the latter to reciprocate. To the projecting upper end of the lever is attached a guide-frame composed of a lower curved bar M and top inclined bar M. In l these bars are guided and supported verticallymovable key-stems N, which have numbered keys N on their upper ends and are upheld by springs N. The downward movement el the stems may be limited by stops u.

On the casing in front o'll the hey-stems when in normal position is a stop M, with which the lower end of any depressed stem (will contact when the lever is moved forward. When any number is to be registered, the correspondingly-numbered key-stem is depressed and pulled forward until its movement is arrested by the stop a, and thus the desired and proper amount of movement is given the registering-wheels by the pawl Cl.

Operation: The operation of the various parts have been set forth in the detail description thereof, but may be briefly recal'iitulated as follows: To add a number, say, in the units-column, the linger-piece c is grasped and lever C pulled forward until the lug c is over the notch d corresponding in number to the figure to be added. The bar c is then depressed, so as to carry the lug ai through said notch. In doing this the corresponding numeral has been brought up to the printingpoint, and as the linger-piece is depressed the bar c actuates the lever c, and the latter through the described connections operates the proper type-hammer E, and the number is printed. The lever C is then pulled forward toward the front of the machine and in so doing moves the correspomling registering-wheel and indicating' numeral-disk accordingly. then the linger-piece is released, the bar c springs upward, lug c passing through the foremost notch and above the lugs d, and the lever C flies back and is ready for another operation. Every time the registering-disk makes ten notches the pawl or dogl ,r/i thereon engages the gear G on the numeral-disk of the next highest denomination and moves the latter and through it its related registeringwheel one notch.

The manner of resetting the numeral-disks to zero and for printing the totals and for feeding paper or traveling the machine have been sufficiently described above.

1 do not restrict myself to the particular mechanism for feeding the papel' herein shown and described, nor do l consider it necessary to have the machine equipped with both paper-feeding mechanisms and with the machinefeeding devices described. Furthermore, l do not restrict myself to the specilic construction and arrangement of parts shown in the drawings, as when their nature and operative relation is understood their form may be changed without altering their functions or avoiding the spirit of my invention.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent thereon, is-
