ADDING-MACHINE.

Specification of Letters Patent.

Patented Jan. 2, 1906.

(LZZ whom, it may concern.-

Be it known that I, WILLIAM FFRLOW SMITH, a citizen of the United States, residing at Jackson, I-Iinds county, State of Mississippi, have invented certain new and useful Improvements in Adding-Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in adding-machines.

The objects of my invention are, first, to provide simple and efficient means whereby any number or combination of numbers may by depressing proper keys be recorded on a tabulating-strip and the summation of these amounts be carried by totaling-wheels and recorded on the tabulating-strip when desired; second, to provide means whereby any number or combination of numbers which may have been written may be erased from the tabulating-strip and at the same time may be deducted from the amount carried by the totaling-wheels; third, to provide an adding and tabulating machine having a minimum number of parts; fourth, to provide means of deducting any number or combination of numbers either with or without placing these numbers on the tabulating-strip, and generally in improving and perfecting the details of a machine for carrying out these objects. I accomplish these objects as will be fully set out in the drawings, specification, and claims.

In the drawings, Figure 1 is a sectional side elevation of my improved adding-machine, showing the number keys, the totalingwheels, and one type-bar only as illustrating the necessary ten type-bars which must be used to give a complete record. Fig. 2 is an enlarged oblique projection of-the gears and racks comprising the totaling portion of the machine. Fig. 3 is a sectional front elevation of the machine, taken on the line III III of Fig. 1, but with the totaling-wheels and the type-bars omitted for purposes of clearness. Figs. 4 and 5 are a plan and side elevation, respectively, showing the carriage, the number-stop, and method of releasing the carriage to return it to any particular position. Fig. 6 is a sectional view of the number-wheels, showing method of picking up the wheels to return them to naught. Fig. 7 is a detail view of the ribbon-feed. Fig. 3 is a detail of the number-key. Fig. 9 is a plan view of the machine. Fig. 10 is an enlarged across from side to side of the carriage.

side elevation of the carriage and platen. Fig. 11 is an enlarged front view of the numberwheels, showing the numerals on this wheel and the spacing between the dime and dollar wheel; and Fig. 12, a view showing the rack spacing corresponding to the number-wheel spacing.

Referring now to the drawings, in which like numerals indicate the same or like parts in all the views, the macline comprises a frame 1,1nade up, preferably, of two sides 2, a front 3, back 4, and bottom 5, which are united togeter preferably by screws 6 passing through lugs on the front and back and fastening into the sides 2. Mounted on this frame is a V-shaped rail 7 and flat rear rail 8, on which run wheels 9 and 10, respectively, there being two wheels 9, one only of which appears in te drawings, which wheels 9 are grooved to lit the rail 7 and guide the carriage 1 1 in which the said wheels 9 and 10 are j ournaled. The carriage 11 carries a platen 12, which is journaled in side pieces 13, the ends of the platen-journal 14 extending beyond the side pieces and resting on the upper surface 15 on the carriage 1 1. 13 extend backward and are pivoted at 16 in a yoke 17, which in turn is pivoted at 18 to the carriage 11.

19 represents arms pivoted on the journal 14 and held in place by springs 20, which connect them with the arms 13, one of the arms 13 carrying a pawl 21, engaging with the ratchet 22, integral with the platen 12, for adyancing the platen at the beginning of a new 23 is a paper guide and shield which is fastened to the arms 13, extensions 24 of which arms carry a paper-reel 25, on which is shown a reel of paper or tabulating-strip 26.

27 is a spring holding the ratchet-pawl 21 into engagement with the ratchet-whcel 22.

28 is a spacing-rack (seen in detail in Figs. 4, 5, and 12) which is pivoted at 29 to the sides of the carriage 11. The opposite end of the arms 30, which carry this rack, are forked and engage a pin 31, carried by a loop-bar 32. This bar 32 is pivoted at 33 to the carriage 11 and is held in its normal position by the spring 34. As seen by reference to Figs. 4 and 12, this bar 32 is U-shaped in plan, extending It will be noted that the rack corresponding with the space between the dollar and dime These side pieces Wheels shown just below is larger than normal, and therefore allows for the extra space taken up by the decimal-point on the dimewheel.

35 represents keys carrying stops 36 on their lower end, which stops depress the U- shaped bar 32 and throw the rack out of engagement with the stepby-step mechanism 37, and by means of a pin 32*, projecting inward, operate the arm 19 and throw it and the ratchet-pawl 2]. to rotate the platen 12. Coacting also with the stops 36 is a stop on the frame of the machine, which limit the motion of the carriage. Referring especially to Fig. 3, it will be noted from the figures shown immediately above each of these keys that they are numbered for cents, dimes, dollars, tens, hundreds, thousands, &c. N ow when any one of these keys-as, for instance, the dollarkeyis depressed and the spacing rack released the carriage can be moved back until the stop 86 on this particular key comes against the stop 38 on the carriage, at which time the dollar-column on the tabulatingstrip will be brought in line with the strikingpoint of the type-bars 39 and at the same time the dollar-wheel on the totaling device is brought into place, as will be more fully hereinafter set forth. The step-by-step motion is effected by the step-by-step mechanism 36, which comprises an arm 40, pivoted at 41 in a post 42 011 the frame 4 and held in its normal position by aspring 43. A vertical pivot 44 extends downward through this bar and carries a piece 45, which is normally held in position shown in Fig. 4 (i. e., at an angle with the arm 40) by a spring 46, which is fastened to the said arm 40 and to the frame 4. A link 47 extends downward into the center of the frame and is connected by means of a bell-crank lever 48, pivoted on a rod 49, extending from side frame to side frame. From this bell-crank lever a link 50 extends forward and is connected to a bell-crank lever 51, pivoted at 52 in a standard 53 to a frame of the machine. At the front end these bell-crank levers 51 are connected by a cross-arm 55, which is operated by the depressing of the number keys, as will be more fully hereinafter described. The operation of the numb er-keys depressing this bellcrank lever 51 operates a ratchet-pawl 56, carried by the bracket 57, which is in turn carried by the link 50. The said ratchet 56, acting with a ratchetwheel 58 through a pinion 57 and a crown-gear 60, rotates a shaft 61, journaled in the side frame 2, which shaft carries the ribbon-spool 62.

63 is a ribbon, and 64 a guide to direct the motion of the ribbon after it leaves the spool 62 to bring it in place for the type to strike It will be especially noted by reference to Fig. 7 that by shifting the ratchetavheel 58 longitudinally the pinion 59 is brought into engagement with the crmvn-whcel 60, so that the ribbon-spool 62 on the opposite side will be thrown into use and the direction of motion of the ribbon be thereby reversed.

65 represents the number-keys, which, as will be seen by reference to Fig. 9, are numbered in a single set from 0 to 9, inclusive. Rods 66 extend downward from these keys, which rods are forked, as shown. in Fig. 8, and embrace levers 67, which are pivotedv in the posts 68, carried by the plate 54. From each of these levers a link 69 extends upward and connects into a cross-bar 70, which bar is pivoted at 71 to one of the side frames 2. These links are held. in their normal position by springs 72, each of which is fastened. at its upper end to individual tension-bars 73, all of which are carried at one of their ends by a shaft 74, extending from side to side of the frame of the machine. At the opposite end each of these bars is carried by a bracket 75, having a tension-screw 76 to adjust it. From the bar 7 O a link and guide 77 extend upward and is forked to embrace a shaft 7 8, which shaft carries a pin-gear 79, which is integral with a spur-gear 80, which spur-gear in turn meshes with a pinion 81 on a shaft 82, and which shaft also carries the master-gear 83. This master-gear meshes directly with number or totaling wheels 84. On the link 77 two racks 85 and 86 are pivoted at the points 87 and 88, respectively. These racks are connected. by a spring 89, which tends to hold them together, and areheld the proper distance apart by a space-block 90, which block is connected by a spring 9]. with the front 8 of the frame. From this space-block 90 a link 92 extends backward and is connected, by means of a bell-crank lever 93, mounted on a shaft 94, and. a second link 95, a rocker-arm 96, and rocker-shaft 97 and. a rocker-arm 98, with the subtract-key 65; When, therefore, the key 65 is depressed, the rack 85 is thrown into engagement with the pin-wheel 79, as shown in the drawings. When this key is released, the opposite rack 86 is brought into engagement with the opposite side of the pin-wheel 79 and. reverses the motion of same. As shown the rack 85 is in engagement and the action of the machine is reversed. These racks S5 and 86 when thrown into engagement with the pin-wheel 79 are held in engagement only by a light spring 89. The upper surface of the teeth of these racks is beveled, as shown especially in Figs. 1 and 2, so that on the upward stroke of the rack the bevel of the teeth causes the spring 89 to give and allow the rack to slip on the pinwheel 79. Thus on the downstroke that one of the racks which is in engagement with the pin-wheel rotates the said pin-wheel, whereas on the upward stroke the rack slips on the pin-wheel and does not cause any motion of same.

The number-wheels 85 are mounted on a .with the said gears 106 and 107.

hollow shaft 99, which in turn is mounted on a spindle 100, which is carried by arms 101, pivoted in opposite sides of the carriage 11 and keyed to a shaft 102, which is rotatably mounted in the said carriage 11. The arm 101 extends upward and is provided with a handle 103, the use of which will be hereinafter described. An extension 1.04 from the arms 101 carries gear wheels 105, which mesh with other gear-wheels 106 and 107, keyed to the number-wheels 84.

Referring now especially to Fig. 2, in which it will be noted that the first numberwheel 84 and the first intermeshing gear 105 have been removed, the number-wheels. 84 have each ten teeth, numbered from 0 to 9, inclusive, and these numbers are in raised figures on the ends of the teeth, the numerals 3 and one numeral 2 showing plainly in the figure. Beginning at the right-hand side of the figure, the numberwheels represent, respectively, cents, dimes,

dollars, tens, hundreds, &c. It will be noted that the decimal-point between dollars and dimes is carried by the number-wheels themselves, being preferably carried, as shown, on the wheel representing dimes, the totalingwheel representing tens of millions having been removed. Between each two numberwheels, as the millions and the tens of millions, (which has been removed to allow a clear view there are two gear-wheels107 and 106. The gear-wheel 107 has twenty teeth or any multiple of ten, though preferably twenty, and is fastened to the tens-of-millions wheel. The gear-wheel 106 is of the same diameter and pitch as the wheel 107; but all the teeth, with the exception of two, (being one-tenth the total number,) have been removed. This wheel is fastened to the adjacent face of the million-wheel, which wheel in its turn carries on its opposite face (not shown) a gear similar to gear 107, and so on. The gears 105 are of practically double the thickness of the gear 106 and 107 and come between the number wheels 84, meshing l/Vhen, therefore, any totaling-wheel is rotated one complete revolution, the two teeth on the gear 106 advance the gear 105, and through this the wheel 107, meshing with it, is also advanced two teeth or one tenth its circum- 'ference, therefore advancing the totalingsuccessively tens of millions, millions, &c., to 1 cents, inclusive. Depressing the numberkey therefore actuates the particular totaling-wheel which is in engagement with the master-wheel at the time that the numberkey is depressed, and when the subtract-key 5s depressed and the rack 85 thrown into engagement with the pin-wheel 79 the action is reversed, so that any number written in with such key depressed is subtracted from the total carried by the totaling-wheels. The master-wheel 83 has its teeth beveled at the edge, so that they come positively into engagement with the number wheels, even though either may be slightly out of place.

108 is an arm extending out from the arm 101 and carrying a series of springs 109, which engage each the face of one of the totaling-wheels 84 to hold them in their proper positions.

Each of the number-keys 65 is connected by a rocker-shaft 111, a second rocker-arm 112, and a link 113 with one of the type-bars 139, which bars are pivoted in bearings 114, arranged in the usual circular are around the inside of the frame 4. Each type-bar 39 is provided with a number, the whole ranging from 0 to 9, inclusive, and is also provided with a blank, as will be seen by reference to Fig. 9. The shift-key 65 is connected, by means of rocker-arms 115 and 116, the rocker-shaft 117 and the link 118, with the U-bar 1.7. By depressing the shift-key 65 the arms 17 are pulled downward and the pivot 16 is shifted forward around the center 18, moving the platen forward and bringing it in line with the blank space on the bar 39, so that any number or any key being depressed while this shift-key is depressed will be printed in solid blanks on the tabulatingstrip.

119 is a post extending upward from the frame 4, carrying a spring 20, which supports the link 118.

121 is a roller which is held against the platen 12 by a spring 122, which roller holds the paper tight against the platen.

The carriage is moved by a spring 123 and a strap 124, attached to the inside of the carriage at a point 125.

The totaling-wheels, as before stated, are mounted on the hollow shaft 99, which in turn is mounted on a solid shaft 100. This shaft 100 is provided with slots 127, as shown in detail, Fig. 6, in which slot are springs 128, which are normally held depressed, as shown, by the solid portion of the hollow shaft 99. This shaft, however, is provided with slots 129 and is so mounted on the shaft 100 that the said shaft 100 may be shifted to bring the springs 128 beneath the slots 129. WVhen this happens, the springs 128 project through the slots 129 and engage the keyways 130 in the totaling-wheels 84. When,

therefore, the number has been written and the total printed on the recording-strip, as will be hereinafter described, the shaft 1.00 is slipped longitudinally and is rotated, the

springs 128 catch in the keyways 130 and bring all the totaling-wheels to their proper place. Since it is desirable that the numberkeys shall all be depressed the same amount, and since the bar is at a 'lixed distance back from the front of the machine, the length of the key-bar from the point of attachment 131 in the link 69 to the pivotpoint in the post 68 is varied as is necessary to secure the proper depression ol the link 69. The link 69, as will be seen by reference to Fig. 3, comes at substantially proportionate distance from the fixed point 71 of the bar 77, so that this variation is only such as is necessary to adjust the slight error in proportion.

The pivot 132 represents the numeral 9, whereas the pivot 183 represents the numeral 1. 0 requiring no motion of the number-Wheel is of course not connected with the bar 70.

The action of the machine is as follows: A roll of paper 26 having been placed in the machine and on the platen 12, the machine is ready for use. For example, it is required to write the amount one thousand two hundred and fifty dollars and thirty-six cents. The stop 35, representing the thousand-column, is depressed and the carriage moved back until this stop comes against the stop 38 on the frame. Then. the thousand-column on the talnilating-strip will be opposite the striking point of the type-bars, and at the same time the totaling-Wheel S41- representing the thousand-column will be in engagement with the master-wheel S3. The number-key 65 bearing the numeral 1 is then depressed, depressing the bar 67, the link 69, the bar 70, the rack 83, and rotating the pin-wheel 79, the gear 80, the pinion 81, the master-gear 83, and through. it the totaling-wheel 84, wnich is rotated one space only. At the same time the type-bar 39 carrying the numeral 1 is by the mechanism hereinbeiore described brought against the platen, and the numeral 1 is printed on the tabulating-strip in the thousand-co mnn. Atthe same time the depression of the bar 67, acting through the bell-crank 51 and the connecting-links 4-7 and 50, depresses the stepby-step mechanism 36 and allows the carriage to move forward one space (as in the ordinary type-writer) to the hundred-column. This action brings the hundred-column on the talnilating-strips to the point of type action and moves the number-wheels 84 representing the hundred-column into engagement with the masterwheel 83. The numeral 2 being now depressed, the action is, before described, on the number-wheel 8 1, except that the hundred-column is being acted on and that the number-wheel is rotated two teeth instead of one, the carriage being again advanced and the number printed on the tabulating-strip, as in the former case. It will be noted that access the movement of the carriage is effected by the release of the key, and therefore comes alter the number has been printed and the totaling-wheel rotated. The numerz'tl 5 is next depressed, rotating the number-wheel in the tens-column 'l'ive spaces and printing the number 5 in the tens-column on the totaling-strip. The number 0, the number 3, and the number 6 are printed in l ke manner. During this time the carriage is moved to the left as is the ordinary typewriter and is new in its extreme lelt position. The column-stop key 35 corresponding with the column with which the next number bogins is then depressed, releasing the rack and spacing the platen, and the (anfriage is moved back until the stop comes against the lixed stop, when the action is repeated, as before. it is of course not necessary to write any naughts in numbers ending in even cents, dollars, or hundreds unless it is desired; but if not written blank spaces are left. hen all the desired amounts have been tabulated, the arm 103 is pulled l'orward. and. the totals on the totaling-wheels 84: are-ln'ought against the talmlating-strip on the platen. 12. The arrow A in Fig. 1 represents the zero-point on the number wheels 8% when they are in position to begin writing a number and also represents the po nt at which the totals are carried by these wheels. The number having been printed on the tabulating-strip, the spindle 100 is pushed to one side to release the springs 128 and is rotated to pick up the number-wheels and carry them back again to 0. When an amount has been written which is ineorrect and it is desired. to remove this amount from the totals, the subtract-key 65 and. the shift-key 65" are both depressed and the amount which it is desired to remove (the platen having been turned to bring the line on which this amount is written. again in place) is written in. The blanks on the type-bars blot out the amount, and the sub tract-key having thrown in the subtractrack 85 the amount written in is subtracted from the totals. Should it be desired to write in a credit, the subtract-key may be depressed and the number written. in, in which case the number so written will appear in the written record exactly as any other would; but the amount of it would be subtracted from the total amount. If desired, of course, the ribbon 23 can be pulled down by hand and a piece of red. carbon-1mper can be used instead of the ribbon, in which. case the numbers would appear written in red and the amount subtracted, which would be the more desirable way.
