CAS1I-REGISTER.

To all whom it may concern:

Be it known that 1, CHARLES {VEAR, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Cash-Registers, of which the following is a specification.

This invention relates to improvements in ing arranged above the former,- and the ink-ribbon is reflexed to extend over the several check-strips, and also between the check-strips and the record-strip, and the ends of said ribbon are connected with or are arranged upon a pair of rolls which are located at one side of the row of strips, and said ribbon passes over a roll which is 1.0-

cated at the other side of said row of strips,,

and push-rods, corresponding in number to the number ofcheck-strips, are employed to feed forward the check-strip and the recordstrip which is associated therewith. Also in said apparatus means are provided for moving the ink-ribbon intermitt-ingly by a movement of the type-writing carriage, to presentfresh surfaces to be impressed by the types, which admitof its being disengaged from its actuator to admit of the type-writing carriage being returned without moving said ribbon, and said means is also arranged to be reversed to cause the ribbon to move in the opposite direct-ion. Moving the inkribboniby the type-writing carriage is objectionable. In the present invention said ribbon ismoved by means operated by any of the ush-rods, intermittlngly but progressive y, and is, therefore, independent of the type writing carriage, and automatic "means are provided for reversing the move- .ment of the ribbonfso that after it has been Specification of Letters Patent.

drawn from one spool andwound upon the other, its direction of movement may be reversed, in order that it may be drawn from the spool upon which it has been wound and wound ,upon the spool from which it was drawn. In carryin out this feature of my invention intermittingly but progressively operating driving-mechanism is provided, adapted to be operatedby any of the pushrods,-and clutches are provided for connecting either ribbon-spool with said drivingmechanism' and at the same time for disconnecting the other spool therefrom, and reversing-means is'provided for the ribbonspools adapted to be operated by the drivingmechanism and shifted by an axial movement of the spools and controlled by the ribbon on the spools, so that when the ribbon has been withdrawn from either spool, said spool is moved axially in one direction for connection with the driving-mechanism and the other spool moved axially in the other direction for disconnection therefrom.

. Figure 1 is a plan view of a cash-registerhavingmeans embodying this invention for supporting and feeding forward the inkribbon. Fig. 2 is a longitudinal vertical section of the apparatus shown in Fig. 1. Fig. 3 is an enlarged front view of the ink-ribbon and actuating-means therefor. Fig. 4: is an end view of the ink-ribbon actuating-means. Fig. 5 is a detail of the shifting-lever for the spools and means to hold it inyielding frictional engagement therewith. Fig. 6 is a detail of the clutch-mechanism connecting the drivingmechanism for the ink-ribbon with the strip-feeding mechanism.- Fig. 7

is a detail of the clutch-mechanism connecting the strip-feeding mechanism with its actuator.

The push-rods are represented at 65 as reciprocable and arranged horizontally and in parallel relation with each other. rods, .when thrust inward, operate means to draw narrow strips of paper 53, herein termed check-strips, from rolls 66 and feed them forward, (see Fig.2), and also operate means to rotate a 1011,50, thereby to draw a wide strip of paper 46, herein termed a record-strip, from a roll 47, and wind it upon said roll-50. The record-strip 46 passes over a platen or M1143; and the check-strips pass over rolls 58. and thence.

formed on. them, for a short distance at their inner ends, and the rack toothed portions of the rods engage toothed-gears 63,

which in turn engage pinions 61, (see F ig.

' 7), mounted loosely on the shaft bearing the rolls 58, and the hubs of said pinions have clutch-members 62, which are pressed by springs into engagement with fellow clutchmembers 64 on thehubs of the rolls 58, so that said pinions may bemoved rotarily in opposite directions to intermittingly but progressively advance the rolls 5S and feed forward the check-strips.

Four check-strips are herein employed,

which are arranged. in a row, consequently four push-rods 65 are provided, each rod having means to feed forward its checkstrip separately, as desired, and the recordstrip which is employed is made wide enough to include'all said check strips and also preferably to provide a portion at one side which extends beyond the endof the row of check-strips An inking-ribbon 100 is arranged to move between the recordstrip and check-strips and also above the check-strips, and'the plates which are arranged about a portion of the platen have holes through them so that upon depression of any one of a set of pivoted type-bars 78, by means of its pivoted actuating-member 85, a record will be printed upon the checkstrip andalso. upon the record-strip.

The type-bars are borne by a carriage which. is movable transversely with respect to-the machine to bring the type-bars into proper position to print upon any of the check-strips, and, as four check-strips are here shown, said carriage has four positions into which it may be brought. for operation. VVhen the ribbon is arranged for operation by a rack-bar, or other means connected with the carriage, as represented in the aforesaid patent, it will be noted that as the carriage is moved from one to another cheek-strip,said ribbon will be corresponds ingly and unnecessarily moved, hence the desirability of providing means for operating the ribbon which is independent of the carriage.

The mechanism embodying this invention to support and to feed forward the ink-ribbon will now be described. 300 represents a pinion mounted loosely on a shaft 301, (see Figs. 4 and 6), and connected by aclutch with said shaft, substantially in'the manner shown in Fig. 7 whereby said shaft 301 is rotatedintermitt-ingly but progressively by the pinion, and said pinion 300 is engaged by the toothed gear 63, see Fig. 2), which is engaged by the longitudinally reciprocat ing push-rod, so that the shaft 301 is operated by the push-rod. Said shaft 301 is arranged horizontally and in, parallel relation with the front of the machine. said shaft 301, there are several pinions 300, one for each gear 63, and push-rod; Said shaft 301 serves as the driving-shaft for the driving-mechanism of the ink-ribbon, and, as here shown, said shaft has secured to it a bevel-gear 303, which engages a bevel-gear 304, secured to a shaft 305, arranged horizontally and at right angles to the shaft 301, and said shaft 305 bears a bevel-gear 306, which engages a bevel-gear 307, secured to a vertical shaft 308, bearing two bevelgears 309 and 310. The gear 309, engages a bevel-gear 312, (see Fig. 3), secured to a horizontal shaft 313, bearing a bevel-gear 314:, which engages a bevel-gear 315, secured to a horizontal shaft 316. The bevel-gear 310, engages the bevel-gear 320, secured to a horizontal shaft 321. Said bevel- gears 309 and 310 are disposed on the vertical shaft 308 in opposite ways so as to drive the shafts 316 and 321 in opposite directions. Two spools 325, 320, to which the ends of the reflexed ink-ribbon are attached are mounted respectively upon said shafts 316 and 321,.

for engagement with fellow-members secured respectively to said shafts 316 and 321, so that said spools are adapted for engage ment with and disengagement from their shafts. Said spools are normally disposed with one of'them in engagement with its shaft, and the other free from engagement with its shaft, so that one spool is positively driven ,to draw the inkribbon' from the other spool by winding said ribbon upon the positively driven spool, and, it will be noted,

that each time any of the push-rods are pressed .inward the driving mechanism for the rlbbon-spools 1s operated lntermittingly but progressively, and the ribbon is correspondingly moved. When the ribbon has been withdrawn from one of the spools and wound. upon the other it is necessary toreverse its direction of movement, and, herein, this result is accomplish-ed automatically by disengaging one of the spools from its shaft and engaging the other spool with its shaft.

As here shown, each shaft 316 and 321 has secured to it a worm 330, 331, and-each spool carries a detent- arm 332, 333, pivotally supported on the spool, the outer" ends of said detent-arms being arranged for engagement with said worms and the inner ends of said arms being extended across the space between the heads of the spools. The pressure of the ribbon upon the-inner ends of said arms acts to depress said ends, thereby to lift their outer ends free from engageise ment with the worms, and springs are employed for moving their outer ends into engagement with the worms when pressure upon their inner ends is relieved, as for instance, upon withdrawal of the ink-ribbon from thespool. As represented in Fig. 4, the ink-ribbon has been withdrawn from the spool 326, and wound upon the spool 325, hence the detent-arm moved into ongagement with the worm 331, and the detent-arm 332 is disengaged from its worm 330, and as the shaft bearing said worm is-rotated with the detent-arm in engagement with the worm. the spool bearing said arm is moved axially and its clutchmember 328 moved into engagement with its fellow-clutchmember, thus connecting said spool with its shaft.

A rocking-bar 340, pivoted at 341, at a point intermediate its length, is arranged at the one end of the two ribbon spools, the ends of said bar. respectively engaging the hubs of said spools, and said baris held by means of a spring 342, connected to its pivot, (see Fig. 5), in frictional engagement with said hubs, so as to retard rotary movement of the spools, thereby to prevent their too free rotation, although said bar is provided more particularly to serve as a means whereby each spool, when moved axially will in turn move the'other spool aXi-,

ally; When the spool 326,.(see Fig. 4), is

moved axially, in a direction toward the left to cause its clutchm embers to engage, said rocking-bar is moved onits pivot, thereby to move the spool 325 axially in the opposite direction, and cause its clutchmembers to disengage, thereby disconnecting said spool 325 from its shaft, and when the spool 325 is moved axially in a direction toward the left said operation is reversed. Thus when either spool is moved axially in a direction toward theleft, for engagement with its shaft, the other spool is moved axially in the opposite direetionfor disengagement from its shaft. Said rocking bar.

' is held in either position it'may be caused to occupy, by means of an arm 345, secured thereto and having its free end made V- shaped and arranged for engagement with a V-shaped block 346, on the frame, the arm occupying a position at one or the otherside of said block according'to the position of the rocking-bar, it passing over said block when said bar is moved. however, not limited to the particular form of driving-mechanism for the spools, or the means here shown for shifting the positions of the: spools .on their shafts, or

controlling their operation.
