operating in conjunction with the rack-bar D will move the carriage A, which is provided with the impression-roller, for a certain distance widthwise of the machine. In the present instance this movement of the carriage A will be to the right of a person oo- 10 cupying a position in front of the machine.

It is intended that whenever it shall be desired to move the carriage carrying the impression-roller for a space to the right, and at a' time when no figure is to be marked down,

the leverll, whose finger-piece is marked with the cipher, shall be operated.

The ribbon G is mounted upon rollers C C. The roller 0 is shown as provided with a handcrauk T, whereby it may be rotated.

The roller C has allixed to it a ratchet-wheel c, which operates in conjunction with the pawl 0', carried by a lever 0 which is connected by a link a with the rear end of the lover I). \Vhen the lever D is raised at the '35 front endby means of the spring D its rear end will be depressed, and will then by means i of the links 0 pawl-lever c and pawl c' effeet a partial rotation of the ratchet-wheel c, and consequently of the roller 0'. In this 40 way the ribbon will be fed along after each stroke of one of the type-levers.

The impression-roller may be rotated to make the spacingbetween lines or rows of figures by any suitable means. As shown, it

is provided for this purpose with a ratchet-- wheel a. With this ratchet-wheel is com-' bined a pawl a, carried by a pawl-lever (L This pawl-lever may be operated directly by srlbrating it with the hand, or it may beoper- 5 ated by any suitable mechanism connected to one of its arms-as, for instance, by a cord a, connected to a stationary part of the frame of the machine at one end and at the other end to the lever, and which may be grasped by 5 5 hand to operate the lever.

The adding mechanism consists of a numv ber of wheels G, severally provided with a definite number of teeth at the periphery. I hzwe shown eight of these wheels. These wheels severally bear upon the periphery a set of figures from Oto 9, inclusive. Anyone of these wheels may be rotated by being I brought into engagement with a wheel H. In

order that any of the wheels G may be brought- 6 5 into engagement with the whecl'H, said wheels G are looselymounted upon a shaft G, which is supported in a frame or carriage G The frame or carriage this free to slide widthwise of the machine along rods G. Tlh'cse rodsG" are supported by brackets Ghwhich are pivotally connected to stands G erected on the base-piece Put the machine. Consequently the brackets l and the'rods- G may be vibrated forwardly and backwardly far enough to remove any of the wheels G which may he opposite the wheel II from engagement with said wheel II or back into engagement with the same. The frame, which is formed of the brackets G and rods G will be normally held in a forward position by means of a. spring G, connected to one of the brackets G and to an appurtenance of the base-piece I, which is stationary.

The carriage G in which the wheels G are arranged, has a movement widthwise of the machine corresponding to the movement of the carriage A in the same direction. The carriage. G is connected to the carriage A by a bar F atj, and derives its movement widthwise (if the machine from the carriage A. It therefore constitutes in effect an appurtenance of the-carriage A, and the movement of .the two carriages is in unison. This motion of the carriage G2 will bring a different one of the wheels G into engagement with the wheel ll, so that it will derive motion therefrom.

v The wheels G are ordinary counting-wheels. When any one. of them has completed a rotation, it imparts a partial rotation to the one indicating the next higher figurc-as, for instance, the units-wheel will, upon c(nnpleting a rotation, effect a partial rotation of the wheel indicating tens, and the latter will operate inthe same manner in conjunction with the wheel indicating hundreds, and so on. I

The figu res on the peripheries of the wheels G may be read between two bars g,-with which the carriage G is provided. As shown more clearly in Fig. 2, each one of the wheels G engages with a gear-wheel G The wheel G, corresponding to any particular wheel G, has a motion similar to that wheel G. Each of the wheels G is provided with a single 5 tooth (see Fig. 4) in addition to the'series of teeth through which said wheel derives motion. The single tooth g of each of these engages once in every rotation of its wheel with the wheel G of the next higher denomi- I20 nation, moving the latter one-tenth of a rotation whenever this happens.

The wheels G, as I have said, are all loosely arranged upon the shaft G. This shaft G is provided with a hand-cranks, whereby it may be rotated. It is also provided with a. number of radially-extending pins 9", as shown more clearly in Figs. 4 and 5. There is one of these pins for each of the wheels G. Each of the wheels G is provided with a short pin 9", adapted at certain timcsto be brought into engagement with the pins g? for the purpose of rotating the wheels G, extending parallel with the shaft G. The shaft G is capabio of light longitudinal movement. Normally itwill be held so that a radially-extending pin g, (shown more clearly in Fig. 4,) with which it is provided, will project into and engage with a cavity g in one of the side pieces of the carriage G It is thus held by a spring g, and when it is in this position its pins'g" will not engage with the pins 01 the 'whcels'G; but if it be pressed longitudinally against" the resistance of the spring 9 its pin g? will-be disengaged from the side piece of the carriage G2 with which it acts, thus leaving it free to rotate, and at the same time the pins 9 will be brought into line with the pins 9. It then the shaft be rotated, it will rotate the wheels Gand bring them all into such positions that their ciphers will be visible between the bars g of the carriage G I will now describe the manner in which ence to others, as shown more clearly in Fig 3. It will be observed that the lever B, whose linger-piece is marked with a cipher, has not one of these lateral projections 1 The'lateral projections of the levers B serve to rock the shaft I when such levers are depressed. Owing to the arrangement of the said lateral projections in different horizontal positions, and as the levers B all have the same range of movement, it will be evident'that the dif ferent levers will effect oscillations of the rock-shaft I different distances from the oth ers, because some of the levers B will move throughout greater distance than the others before acting upon the rock-shaft.

The rock-shaftI is provided with a toothed sector-lever I. One arm of this lever is connected to a spring 1*, which returns the lever and the rock-shaft I to their normal positions.

, This toothed sector-lever engages with a pinion 1", aflixed to 'the shaft upon which the wheel II is mounted. There is also aiiixed to this shaft a ratchet-wheel I". \Vhen the sector-lever I is vibrated by the depression of one of the levers ll, it will rotate the pinion I and also the ratchet-wheel I in such direction that the latter, coacting with .the pawl 1 which is pivotally connected to one side of .the wheel II, will impart a rotary motion to said wheel H for a certain distance a rock-shaft J.

opposite to it.

The wheel .1 l is shown as having combined with it a pawl or detent J, which is affixed to affixed to it two fingers J 2 J. The forward end of lever D' plays between these fingers J This rock-shaft 'J' has also hen the lever l) is depressed at the forward end, it will depress the-finger J and so oscillate the rock-shaft J as to cause the detent'J to engage withthe teeth of the wheel II. This detent will then hold the wheelll stationary until the forward end of the lever Dinrising comes in contact with the finger J and oscillates the shaft- 5 in the'reverse direction, so asto disengage the detent J from the teeth of the'wheel II. These ocillations of the rock-shaft J are so timed that after the completion of that oscillation of the rock-shaft I and sect-or-leverl", which is produced by the depression of a lever B, the

wheel H will-be locked, so that the reverse oscillation of the rock-shaftl and the sectorleverI", which is effected by the springl, will not produce any rotation of the wheel II by any accident, and also so that after the completion of this last-referred-to oscillation of the rock-shaft I-and sector-lever I the detent J will be disengaged from the wheel H, so as to leave it free to be again partially rotated upon the oscillation of the rock-shaft l andsector-lever l by the depressionof a le-- ver 15.

Instead of combining wit-h the rock-shaft J the fingers J J and the detent J, I may, as I have illustrated by Fig. 7, combine with the wheel H a ratchet-wheel II, affixed rigidly to one side of it. Then a'stoppawl, which will permit it to rotate in one direction but pre- Vent it from moving in the other direction, will'serve every purpose.

The writing mechanism of the machine which I' have described records the various sums to be added, and the adding mechanism makes the addition. The addition made by the mechanism may be afterward written at the foot of the columns of figures previously recorded. During the writing of the addition the adding mechanism'may be rendered inoperative by vibrating a lever 'O. This lever is fulcrumed between its ends to .an extension from the carriage G The forward end of the lever bears against a stationary plate 0', and the lever is of such length and extends at such an angle forward of the pivot-frame that'when vibrated in one direction its forward end may operate with a cam action upon the plate 0, and thereby swing backward the frame composed of the brackets G and rods Griso as to remove from engagement with the wheel II whichever one of the wheels G was previously in engagement with it.. When vibrated into a position tooperate as described, it may, if desired be locked in that position by a hook 0 When the frame consisting of the brackets on and rods G is thus thrown back, 'so' as. to render the wheelsG inoperative, the writing mechanism may be operated without producing any effect upon the adding mechanism. When, however, it is desired to th emove the wheels G out of possible engagement with the wheel l1 and to provide for moving the carriage A and the carriage G2 into any my sired position, the lover may be vibrated a little farther, so as to impart longitudinal moliou to a bar which is connected with it by being provided with aslot that receives a pin that extends from the lever. \Vhen such motion isirnpartcd to the bar 0 it imparts motion to a bar 0, which is pivotal'ly connected with'crank-arms O". The lougio the impression-roller. The pawl 'D when thus elevated is rendered inoperative, so that the carriages G2 and A may be moved width wise ofthe machine at pleasure.
