JOHN. DESMOND HAYES, OF NEW YORK, N. Y.

CALCULATING-MACHINE To all whom it may concern:

Beit-known that I, J OIIN Dnsnonn HAYES, a citizen of the United States, residing at New York, borough of Brooklyn, in the county of Kings and State of New York,

have invented a certain new and useful Calculating-hlachinc, of which the following is a specification.

h'ly invention relates to calculating ma.- chines of that class wherein memoranda of the sums to be added, sub-footings, totals, and other data are printed by the operation of printing mechanism so as to produce a permanent record. v

In the operation of machines of this class it is a common practice for a book-keeper or accountant to list the individual sums by printing the several amounts in a column on a record sheet. It frequently happens that it is desirable or necessary to obtain an addition of the sums listed before the operation of listing all the sums is completed, and the operator then proceeds to.

operate the machine so 'as to secure a subfooting, after which the work of listing the balance of the sums is proceeded with, and

finally all the sums of the list are added together so as-to secure the total. Ordinary 4- u o I 'maclnnes print the impressions of the individual sums, the sub-footings, and the total all in one and the same color, on a record sheet or tape, so that the sub-footings cannot be quickly distinguished from the sums of the list. This leads to mistakes on the part of the accountant in comparing the checks with the individual sums of the list.

One object of my invention is to obtain a record wherein sub-footings and totals of the sums appear in a color contrasting with that of the list of the sumsthemselves, thus eliminating the liability of mistakes on the part of the accountant in checking off or comparing the list of the sums with the checks, or other data.

A further object is to provide mechanism whereby impressions of the sums to beadded, of the sub-footings, and of the totals, may be printed in different and contrasting colors by the aid of a multi-color ribbon or of a plurality of ribbons.

A Broadly stated, the invention consists of mechanism operating in conjunction with a printing, mechanism whereby the sub-foot- Specifica.tion of Letters Patent.

the color of the printed impressions of the individual sums.

In one embodiment of the invention I employ a ribbon of a difl'erent color from the record ribbon through which the printing mechanism operates to make impressions on a record sheet or tape of the sums to be added, the aforesaid color ribbon being movable across the last nalned ribbon. With the said color ribbon is combined a guide mechanism for holding it, normally, out of the path of the printing mechanism. Said guide mechanism is adapted to be operated, preferably, by the key, lever or other element which operates the adding mechanism for the purpose of printing the sub-footing or the total of the column of figures, whereby the guide mechanism operates to sl ift the color ribbon into the path of the printing mechanism and thereby to print through said color ribbon and secure an impression on the record of a sub-footing or the total in a different color from the printed impressions of the sums which are listed on the record.

In another embodiment ofnly invention,

machine of standard construction which .uses a single color ribbon, of a multi-color ribbon, say of two contrasting colors, in corn nection with operating means whereby such multi-color ribbon may be operated to bring either of its color sections into the path of the printing mechanism. This enables'an operator to use the machine in the usual way for the purpose of securing a record. of the sums to be listed in one color; or if desired, a multi-color ribbon may be shifted to one operating position so as to produce a record of the sub-footings in another color, and, furthermore, the multi-color ribbon may be shifted to a still further operating position so as to secure a record of the totals in still another color. all three of said records being in contrasting colors so as to be distinguished from each other at. a glance. 1

In the drawings, Figure l is a side elevation, partly broken away, showing my invention in connection with one of the well known adding machines of the type known as the Bnrroughs machine, said figure illustrating more particularly the parts comprising the invention and omitting practically mgs and the totals may be printed on a all the operating devices of the Burroughs record in one or more colors differing from machine. Fig. 2 is a cross section on the 1 line 2-2 of Fig. 1, showing the new devices 'in rear elevation, substantiallyrall the operating mechanisms of the Burrouglis machine being omitted. Fig. 3 is a detail View show- 5 ing a multi-color ink ribbon adapted for use in connection with the usual single color ink ribbon of the printingand registering mechanism of the ordinary machine, such multi-color ribbon being especially useful when it is desired to secure impressions of the sub-footings in one color and impressions of the grand totals in still another color, said impressions of the sub-footi'ngs and of the grand totals being in contrasting colors to impressions of the list of individual sums and to each other. Fig. 4 is a detail view in side elevation of a form of key-operated means for adjusting the multi-eolor ribbon shown in Fig. 3 to a number of positions whereby the different sections of said ribbon may be brought into alinement with'the registering and printing mechanism of an ordinary adding machine.

Fig, 5 is a vertical sectional elevation of a Burronghs adding machine disclosed in Patent 'No. 3S8,119, dated August 21, 1888, showing enough of my invention to illustrate its application to said machine. Fig. -6 is-a detailsectional-elevation of the regis tering and printing mechanism of.said Burroughs machine with my invention in position for cooperation with said registering andzprinting mechanism. Fig. 7 is a detail plan view of the parts shown in Fig. 6 representing the old-well known form of register Wheels and certain operating devices associated therewith as fully disclosed in the aforesaid Burroughs patent.

I will first describe my invention as illustrated, mainly, in Figs. 1 and 2, and in a modifiedgform'in Figs. 3 and 4, after which the application .of the invention to a Burroughs machine of the aforesaid patent Wlll 'bel briefiy referred to in connection with Figs. 1, 2, 5, 6 and 7 in order that a sufficient disclosure will be given in this specifieation for others skilled in the art to construct and use the invention.

, My invention as shownin Figs. 1 and 2 cmbodies a plurality of hangers which are spaced relatively to each other and support the uides, G, G, for an ink ribbon, H, or H (-the latter being shown in Fig. 3). Said hangers, B, B, are supported within the easing or frame of the adding machine and in fixed positions therein, it being preferred to piace said hangers on a cross rod, A, and to hold said hangers rigidly on said cross rod byclamping screws, 6.

As shown in Fig. 2, each hanger, B, is provided at its lower portion with afoot.- piece, 'f,'and rigidly attached to this footpiece are depending guide rods, f, two of Said rods being preferably employed on.the foot-piece of each hanger. Each ribbon guide, G, is, preferably, a single flat: plate which is slidably fitted on rods, 7', of one hanger. Said ribbon guides are adapted to slide-freely up' and down on said guides of the hangers, and normally said ribbon guides are pressed toward the lower ends of :aid hangers by coiled springs, g, the latter being held in place by fitting them loosely on rods, f. Guides, G, are provided with slots, g, and through these slots passes an ink ribbon, H, the latter being independent of record ribbon, C, presently'referred to, and being movable across one face or side of such record ribbon. Ribbon, H, is adapted to be coiled on a spool, 72, which is made fast with shaft, D, the latter carryingone spool, c, of record ribbon, C. .Said ribbon, H, passes from spool, la, through a slot, 9', of one ribbon guide, G, thence across record ribbon, C, thence through slot, g, of other ribbon guide, G, and to another spool, It, which is fixed to shaft, D, adapted-to carry spool, c, of record ribbon, C, as shown in Fig. 2, Shaft, D, is shown in Fig. 2 as hav-' ing afeed ratchet, (1, adapted tobe engaged by a pawl, (Z', on a feed lever, (Z so that shafts, D, D, areadapted to be operated in a manner. well understood by those familiar with the Burroughs adding machine, for the purpose of imparting movement to record ribbon, C, and of reversing the direction of movement automatically of said record ribbon when the latter reaches the limit of its movement in one direction. The ribbon, H, of my invention is intended to be of the same length as the record ribbon, C, and by placing the spools, h, h, of ribbon, H, on shafts, D, D, which operate said record ribbon, C, 1 am enabled to automatically feed ribbon, H, and, also, to reverse the direction of movement of ribbon, H, simultaneously with the reversal of movement of the record ribbon, as will be readily understood. Normally, guides, G, G, and ribbon, H, are depressed by springs, g, below. the printing position, or out of line with the numeral wheels'of the register and printing mechanism of the machine. Under these conditions, the numeral wheels operate against inked record ribbon, C, to print a list of'sums in the color of record ribbon, C, on a tape, of paper or other material, passing in rear of impression roll, E see Figs. 1 and 3. For the purpose of bringing ribbon, H, of my invention intoposition for securing an impression on'the tape, which impression will differ in color from those of ribb,on,.-C, and correspond to the color of ribbon, H, means are employed for operating ribbon guides, G, G, so as to lift them, and ribbon, H, to the required position so that ribbon, H, will be :in line with the numeral wheels of the register and printing mechanism.

The ribbon lifting mechanism is indemay use a wider ribbon so that. it may conpendent of all theothei operatiug mechanisms of the adding machine, that is, it is manipulated or adjusted by hand for the purpose, merely, operative position. ()ne emlaulin'ient ot such means consists of a key, K, mounted for sliding movement in the. usual key board 2', '4', the lower end of said key being pivoted to a long arm of an elbow lever, the latter being pivoted at To the other arm of said elbow lever, Z is pivoted a link, in, the other end of which has a slot, ll, through which slot passes a pin, 0, adapted to connect said end of link, 12/, with an arm, 0, of a rock shaft, 0. This rock shaft is provided with tappet arms, 1, which extend downwardly and reari'vardly toward the ribbon guides, G, and the free ends of said tapp'et arms are adapted to' engage. with lugs, 1 which are provided on said ribbon guides, (t. The depression of the key, K, operates lever, In, link, or, and shaft, 0, for the purpose ot raising tappet arms, P, and these tappet arms operate simultaneously on guides, (l, so as to lift said guides and ribbon, H, against the tension of springs, 3 wherelrv ribbon, H, is lifted into the path of numeral wheels on the register and printing mechan ism, so that said mechanism will cooperate with record ribbon, (f, color ribbon, ll, and impression roll, BIZ-for the purpose o't print:- ing a total of the sums to be added on the record sheet or tape, E, such totals being in a 'difi'erent color from the list of the indi-. vidual sums which are. printed, also, on the record sheet or tape. When the pressure on key, K, is removed, springs, g, press ribbon guides, (i, downwardly, thus moving ribbon, H, out oi. the path of the register and printing mechanism.

My invention is not restricted to a single color ribbon, such as H, because I may employ a mu ticolor ribbon, similar to ribbon, ll, substantially as shown in Fig. 3. Said ribbon, ll, may be wide enough to have only two colors, as shown, or, if desired, I

tain more than two colors. this embodiment of the ribbon, ll, is adapted to pass through guides the same as slotted guides, (1}, shown in Fig. 'Said ribbon, TI, is adapted to occupy three positions, in one of which is out ot the path of the register and printing mechanism; in the second position, the 1"ib bon is arranged for one of its color sections to lie in the path of said register and printing tmxclmuism, while in the third position of said ribbon, H, the other color section thereof is in the path of the register and printing mechanism, whereby ribbon, H, is adapted to print on the record sheet or tape, i impressions of the sub-footings and of the totals in dillerent colors from each other and in contrasting colors to the impressions According to invention, the wide of bringing ribbon, H, into of the sums which are printed by the machine with tl aid of record ribbon, (I, alone.

The employment of multi-color ribbon, II, necessitates the provision of means in conjunction with spring-depressed ribbon guides, G, G, for lifting said guides and ribbon, H, to two or more different. positions depending upon the number of color sections of said ribbon. As shown in Fig. 3, ribbon, H, has two color sections, and in Fig. at there is represented one embodiment o] a key and its associated parts whereby lever, 7c, and tappet arms, P, may be operated so as to lift guides, G, G, and ribbon, It, to two ditt'erent positions, whereby elevation of ribbon, H, to one position brings one color section thereof into the plane of the register and printing mechanism, Whereas the elevation of said ribbon, H, to its highest or second position brings the other color section thereof into similar alinement with the register and printing mechanism. With said elbow lever, is, is associated the key, K, heretofore described, and in addition thereto Icmploy the key, K, the travel of which is limited by stops, 1, 7*, the latter being attached to the stem of said key, K, and cooperating with plates, '1', 2', of the key board in a manner to arrest the movement of key, K, within certain limits. key, K, is provided with a slot, 8, in which operates a stud, 8, fixed to long arm of elbow lever, /r. Said keys, or either of them, are operated by hand separately from the other parts of the adding machine, and said keys serve to give variable movement to the ribhon-shifting guides, G, G. .The depression of key, K, is arrested by stop 1, and said key acts on stud, s, for moving lever, 70, and the ribbon guide mechanism a limited distance, whereby ribbon H, is raised just far enough to bring one color section thereof into the printing plane of the register and printing mechanisn'i. The other key, K, however, may depress the long arm of lever, 7.", to a greater extent, and thus the ribbon shifting mechanism is operated for raising ribbon, H, to its second position, whereby the other-color section thereof is brought opposite to the numeral Wheels of the'register and printing devices. When lever, la, is pressed down by the depression of key, K, stud, 8', travels idly in slot, 8, and key, K, is at rest.

As thus far described, the invention embraces the, employment of two ribbons, one of which maybe a multi-color ribbon, said ribbons being arranged for movement one across the other. This brings the ribbons in contact at the intersection of their paths, and the color of one ribbon is thus liable to be smeared otf, or be transferred, to the other ribbon. To overcome this, it is proposed to employ means for separating the ribbons at their point of intersection, and

The stem of which permits the printing mechanism to cooperate with said ribbons and the impression roll for securing the printed impressions on the recorm sheet. I may en1- ploy a thin sheet of rubber as the separating sheet, and support or carry the same on the ribbon guides, G, G, although other materials than rubber may be used, and other means for supporting and operating the separating sheet may be adopted.

For the purpose of showing my invention applied to an ordinary adding machine, I have illustrated in Figs. 5, 6 and 7, some of the operating parts of the Burroughs machine embraced in Patent No. 388,119; heretofore mentioned.

As shown and described in said patent, a

register and printing mechanism, L, is employed in conjunction with meansfor actuating the same in order to adjust the numeral wheels according to the operation of appropriate keys, indicated at I, said keys operating in an appropriate key board, 2', As shown in Figs. (3 and 7 the register, L, comprises numeral wheels, 21, having radial arms,', the ends of which are provided with numerals adapted to serve as printing faces. Said wheels are parricd on shaft, 23, and each wheel is provlded with a gear, 22. With said gear, 22, of each numeral wheel meshes a rack, 25, on a rear section, 103, of a twopart rocking lever, F, the front section, 102, of said lever, F, being provided with a curved rack, 30, The two sections 102, 103,

. of each lever, F, are hung on shaft, 1, of the machine, and they are so combined or related that said sections are adapted to operate conjointly under certain conditions, whereas under other conditions, the sections are capable of limited independent movements in the manner and forthe purposes specified in said patent. Cooperating with said rocking levers, F, are four main devices, viz. first, a retainer which holds the front section, 102, of said lever normally in a given position; second, devices operated by the keys which release the lever to permit its automatic operation to register a number; third, a regulator which determines the extent of the levers movement in accord; ance with the figure to be brought into position by the register; and, fourth, a carrying device, which automatically imparts an additional movement to the next actuating mechanism when the addition of numbers requires it. Furthermore, the machine is equipped with a frame, FF, which carries the impression roll. E and this frame is hung on a shaft, 0, so that the frame may be rocked under the action of a. spring, thereby carrying the paper against the inked ribbon, 0.

Said frame is adapted to be pressed outwardly by an arm,'S connected with lever 135, when said lever swings with shaft, 3, see Figs. 5 and 1. Ribbon, C, is coiled on spool, c, of shaft, D, said ribbon leading downwardly bet-ween wheels, 21, of register, L, and impression roll, E and the other part of ribbon is adapted to be coiled on spool, c, of shaft, D. The several mechanisms are operated automatically from a device termed a driverf, T, adapted to reciprocate on an inclined guide rod, 155, said driver being operated by the hand or foot of the operator, and the driver being connected operatively with cam arms, 158, attached to rock shaft, 1, and also connected with a train of devices for operating frame, K formingan element of the carrying devices.

As all the aforesaid mechanisms, and their mode of-operation, are fully set forth in the aforesaid patent, and as said old form of machine forms no part of the present invention, I do not consider it necessary to fully illustrate and describe the construction and operation of such machine, more particularly as the same will be apparent by an examination of said patent.

When my invention is used in conjunction with the machine of said patent, the hangers,

B, B, are mounted on a cross rod, A, of the machine, or on a special cross rod provided for the purpose, in order that hangers, B, and guides, G, may be positioned at the respective sides of record ribbon, C. Spools, 71., 7a, are placed on shafts, D, D, which operate spools, 0, c, of record ribbon, G, and ribbon H, or H, is led from one spool, 0, through slots, 9', of guides, G, and thence to other spool, c, or vice versa, whereby ribbon, H, or H, is adapted to cross ribbon, C,- see Fig. 2. When ribbon, H, is used, key, K, is provided-at one side of key board, 71, i,

and lever, 70, shaft, 0, link, m, and tappet arms, 'P, are properly installed substantially as shown in Fig. 1.

In the operation ofthe machine of Fig. 1, the parts are manipulated or worked'in the manner set forth in the aforesaid patent when it is desired to add the sums and to print or list the same on the sheet or tape passing between the register, L, and impression roll, E said list being printed in a color corresponding to the color of the record ribbon, G. hen the total or footing of the sums is to be obtained, my devices are adjusted as follows :-key, K, of Fig. 1 is depressed for the purpose of operating elbow lever, Za, shaft, 0, and tappet arms, P, so as to raise guides, G, whereby ribbon, H, is placed between register, L, and roll, E Now when the machine is operated, roll, E, is pressed inward so that the printed impression of the footing or total will be made on the tape or sheet by register L, acting on the ribbon, H, whereby the list of sums is obtained in one Y in still another color of the color and the footing or total is obtained in a different color. When key, K, is released, the parts return to normal positions and ribbon, H, is depressed to the position of Figs. 1, 2 and 5. The operation of the machine in the usual way may now be resumed without hindrance from the mechanism associated with color ribbon, H.

Said Patent N 0. 388,119, describes the construction and operation of mechanism associated With rocking levers, F, (F) and register, L, (E), whereby a total ofthe footing may be indicated on and printed by the register, and in addition thereto, the register may retainthe total, termed a subtotal in order that other numbers may be added on or by the register, for the purpose of securing a grand total. It is desirable in this connection, first, to secure a printed impression in one color of the list of sums, second, a printed impression in another color of the sub-total or sub footings of the More said list, and, third, a printed impression grand total of thesums. My multi-color ribbon, H, operating in conjunction with record ribbon, C, and shifted by mechanism such as shown in Figs. 1 and 4, provides means whereby these several impressions in different and contrast ing colors may be obtained easily and quickly. To explain :-The adding machine is operated in the usual manner to secure printed impressions in one color on the tape by aid of ribbon, C, of the list of sums to be added, ribbon, H, being out of the path of register, L. For securing a printed impression on the tape in one color of the added sums key, K, of Fig. 4 is depressed, and guides, G, are raised a certain distance, thus lifting ribbon, H, into position for one of its color sections to be opposite the printing surface of register, L,.whereby the machine is operated to add the sums and to print the added sums in one color on the tape, such printed impression corresponding in color to said color section of ribbon, H, and being of a different color from the impressions of the list of sums. Pressure being removed from key, K, guides, G, and, ribbon, H, are pressed downwardly by springs, g, and the operation of the machine may be resumed in order to continue listing the sums on the taoe. to be taken, the operator depresses key, K, and ribbon guides, G, and ribbon, H, are moved to their highest ositio'ns, thus bringing the other section of multi-color ribbon, H, into position between register, L, and roll, E The operation of the machine'to print the grand total "causes the impression to be taken from said color section of ribbon, H, and thus the printed impression ofthe grand total is obtained in a color diifering from those of the individual sums and the sub totals. By releasing key, K, the

Now when the total-of all the sums is ribbon, H, guides, G, and other parts are returned to normal positions, and the operation of the machine may be resumed in the usual manner.

Although for the sake of explanation I i have shown and described my invention in connection with a particular form of adding mechanism, it. is to be distmctly understood that the invention is not restricted to its use in conjunction with said adding mechanism. For example, my new devices may be used in connection with the adding mechanb'ons of contrasting colors arranged to intersect and adapted to cooperate with said printing mechanism whereby records of individual sums, and totals or footings of such sums, may be obtained in contrasting colors. 7
