LEICESTER ALLEN, OF BROOKLYN, NEV YORK.

MACHINE FOR BOOKKEEPING AND REGISTERING CASH.

SPECIFICATION forming part of Letters Patent No. 570,620, dated November 3, 1896.

Application filed October 16, 1895. Serial No. 565,773. (No model.)

To all whom it may concern.-

Be it known that I, LEICESTER ALLEN, of the city of Brooklyn, county of Kings, and State of New York, have invented a new Machine for Bookkeeping and Registering Cash; and I do hereby declare that the following is a full,clear,and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

My invention is designed more especially for use in savings-banks or institutions of like character for insuring accuracy in and facilitating the recording of deposits and of amounts paid out on account of depositors, and to enable the proper oflicers at all times to ascertain in briefest possible manner, and without the trouble of footing, the amounts which have been received and paid out from any prior time or date to the time or date of their examination of the state of the bank, within any prescribed practical limit of time; but, while thus stating the primary object of the invention, it is not intended to limit its scope to savings-banks alone, as it may find a useful. application in banks of deposit, lifeinsuranee offices, and, in general, in any business office or counting-room where frequent cash payments are received and disbursed and recorded on pass-books or paper slips. The example of the invention herein described is, however, that designed for the special use of savings-banks, for which purpose it performs the following functions:

First. It prints on the pass-book of the depositor the date and amount of his deposit or the amount drawn by him, the same general form of the machine being used by the paying-teller as by the receiving-teller, and the only difference being in the use of the words receivec and paic impressed on the book by the printing mechanism of the machine, this use of either word entailing only a different adjustment of one of the type wheels or rings hereinafter described. The form preferred for printing receipts of money is as follows: June 30,1894:, Recd 0.50; and for payments on account, June 30, 1894, paid 30.25. The use and purpose of the asterisk preceding the significant figures in these forms will be herein inafter explained. may be used.

Any other desired form Second. Simultaneously with printing the pass-book the machine prints on a concealed tape in. a locked box the number of the passbook and the amount credited or debited on the book, the date of the transaction being written. or stamped on the tape, once for all, at or prior to the beginning of the days business. This record constitues a second entry, and the tape can be removed by any authorized official at the end of each day for use the next day in transferring the entries to the books of the institution, and can then be preserved for future reference.

Third. By means of an adding mechanism or register correlated with the other mechair ism, whereby the previously-named records are made, each sum deposited or paid out is added to the total previously received or paid out, say from the first beginning of the business of the bank to the date of such transaction, so that at any time or date by simply subtracting from the total exhibited by the register the total previously deposited or paid out the amount received or paid out since such previous time or date is determined. In regular business this enables the proper oiiicer to ascertain in a verybrief time, without waiting for footing, and by simple inspection, the amount of money which the receiving-teller has taken in and the amount which the paying-teller has paid out on account, and, in case of a run on the bank, enables the officers, with very little trouble, to ascertain hourly or half-hourly the amounts which have been withdrawn and compare these with amounts deposited.

The invention consists in various mechanisms and combinations of mechanism, which may generally be classified as follows: First,

key mechanism or manual, consisting of a keyboard, key-slides, keys, key-slide stops, mechanism for restoring keys and key-slides to the normal or first position, pawl mechanism for holding the key-slides in the position where they are placed by the operator until they are automatically released after printin g and registering each amount received or paid, and keybuttous of peculiar form and function; second, drop-slide mechanism related with the key mechanism, whereby, through the action preferably of gravity, (but it may be by the action of springs,) the ad- ,iustment of the type wheels or rings is ef- 'fected for the printing of any amount within the scope of the machine and a limit for the action of the adding mechanism is fixed in such manner that precisely the amount printed is added to the previous total; third, a peculiar construction of type wheels or rings and of mechanism for supporting and operating them, directly connected and re la-ted with the drop-slides, whereby, through the primary movement of the keys and keyslides in the manual, thetype wheels or rings are automatically brought to the right position for printing the amounts corresponding with the keys and key-slides manipulated by the operator; fourth, the adding mechanism or register related with the drop-slides, though not directly connected therewith, and cams, shafts, levers, and gearing for operating this mechanism by power applied to a hand crank or shaft; fifth, a platen for supporting the pass-book to be printed, with peculiar mechanism thereunt-o attached for receiving, adjusting, and holding the book in right relation with the type-wheels, and also supporting and operating attached. mechanism for inking said wheels in a peculiar manner hereinafter set forth; sixth, an inking mechanism comprising inking-rollers for receiving, holding, and distributing ink to the types during the motion of the platen; seventh, a locked box for containing the aforementioned tape and mechanism for bringing the tape into relation. with the type wheels or rings to print it simultaneously with the print-ing of the book; eighth, a system of graduated lifters attached to the drop-slides, whereby the operator may see whether he has operated the key mechanism properly before printing, and whereby, if he chances to have set the wrong types in position, he may set any key-slide which is in a wrong position back again independently to its zero position and reset it prior to printing, thus enabling him to readily detect any errors in setting and correct them quickly; ninth, mechanism whereby, when. the crank which operates the register-cams is turned by a hand-crank, the platen and the tape-box are both actuated simultaneously for printing, and an automatic con'ipensating mechanism for printing on different thicknesses of passbooks; tenth, mechanism whereby, through the motion of the crank that operates the printii'ig and registering mechanism, all parts, except the platen, are restored to the normal or zero position after the printing and registering have been done; eleventh, a bedplate of peculiar construction, which supports the working parts, and other minor constructions hereinafter described; twelfth, a. printing-head which carries type-rings of peculiar construction, each of which is automatically moved, in a manner hereinafter described, by its proper drop-slide mechanism whenever the latter is set free to move by the movement of its proper key-slide, and

other type rings for printing the words Recd or Paid and the dates; thirteenth, lining mechanism which acts automatically, in combination with. the crank-shalt of the printing mechanism and the type-rings on the printing-head, to bring the types, when about to print, into line and hold them in line during the act of impression.

Figure l is a front view of the machine, a portion of the front plate being broken away and the drop-slide lifters being removed to show other parts. Fig. 2 is a detail view of stop mechanism whereby at a period nearly or quite simultaneous with that when the parts are brought to the zero position the motion of the crank actuating the mechanism. is brought to a positive stop, so that it cannot be moved any farther till again released, as hereinafter more particularly described.

Figs. 11 and 12 are respectively a vertical section and a front elevation of a key, showing the :form of the key-button and key-pawl and a spring, one of which is attached to each key. Figs. 12 and 12" illustrate a detail of the key-slide construction. Fig. 13 is an enlarged partial section on the line 90 5c in Fig. 9, but showing parts in a different position and exhibiting some details of construction that cannot be conveniently shown on the smaller scale of the similar section shown in Fig. 10. Fig. ii is adetailview of mechanism attached to three of the dropslides, whereby their action is modified, for a purpose hereinafter described. Fig. 15 is a section through the printing-head, made on a plane corresponding with the axis of the shaft which supports the head and showing the in terior mechanism of this head. Fig. 16 is a vertical central section through one of a set of in ternally-toothed rings and its support, by

- which ring, when actuated by one of the dropslides attached thereto by a link, motion is imparted through a pinion to the correspond ing one of a set of shafts carrying toothed wheels in the interior of the printing-head, each of which intermeshes with the teeth of its proper type-ring, as hereinafter explained. Fig. 17 is an enlarged top view of the adding mechanism or register with a part removed, the latter being shown separately in Fig. 18.

There are in this example of my invention twelve key-slides 1, Figs. 1, 3, 9, 10, 11, 1.2, and 12 each forming part of the manual or keyboard mechanism which the operator manipulates in setting the mechanism into position for printing the pass-book and the concealed tape and for registering the amount so printed; but the number of these keyslides may be more or less, according to the purpose for which the machine is designed, and I therefore do not limit myself to any particular number of them. Each of these keyslides carries a set of keys 2, Figs. 1, 3, at, 9, 10, 11,12, and 13. The key-slides are preferably made in the form of a hollow parallelepiped or rectangular tube, the bottom side being cut away, so that only three sides of the tube remain. On the front end of each keyslide (that is, the end before which the operator stands in using the machine) is formed an extension or tang 3, which is turned clownward at a right angle with the body of the key-slide, as shown in Figs. 1, 4c, and 10, and to the opposite end is fitted and attached by riveting or brazing, or both, a hardened steel block 4, Figs. 10, 12 and 12 The keys 2 are shown in detail in Figs. 10, 11, and 12. Each is formed of a key-pawl 5 and key-button 6. The key-pawl works on a pivot 7, which connects it with the key-slide, as hereinafter described, and it has a horizontal extension toward the front, as shown in Fig. 10, and a vertical extention upon which the socket 8 of the key-button G is fitted, as shown in Figs. 11 and 12. The key-pawls and key-button sockets are of metal, and the bodies of the key-buttons are of celluloid or other suitable composition that can be molded into the proper form and pressed into the hollow part of the socket, so that when the molded bodies harden they become fixed in their sockets, as shown in Fig. 11. The key-button sockets are removably attached to the key pawls by a pin 9, which is passed through a holein the lower part of the socket and a corresponding hole in the upwardly-projecting part of the key-pawl. The pivots 7 are also removable, being fitted easily into the holes in the lateral walls of the key-slides without riveting or pinning and, when in use, being held in their places by rib-bars which hold the keys laterallyin proper positions, as hereinafter described.

In the middle of the under side of the hub of each key-pawl through which the pivot 7 passes is milled out or otherwise formed a recess 10, Figs. 11 and 12, which is deep enough to allow a wire spring 11 (shown only in Figs. 11 and 12) to pass entirely around the pivot. One end of this spring bears against the under and inner side of the upper wall of the key-slide and the other against the inner surface of the recess 10. The key is thereby held in position relatively to the key-slide, as shown in Figs. 10 and 11, at all times when not operated, as hereinafter set forth.

The bodies 6 of the key-buttons are cylindrical at the base, but are cut away on the front and back to leave inclined facets 12. On each facet presented toward the front of the machine is placed a numerical figure, as shown in Fig. 12. The unnumbered facets which face away from the operator are those to which the fingers of the operator are applied in using the machine.

The upwardly-projecting parts of the keypawls which support the key-buttons are cylindrical, and they pass through holes 13 in the upper wall of the key-slide, these holes being enough larger than the parts of the keypawls that pass through them to permit a rocking motion of the key-pawls on their pivots '7.

The key-slides are fitted to slide longitudinally on the upper horizontal surface of a metal keyboard let, Figs. 1, 3, 10, 10 10 11, and 13. This keyboard is preferably made of cast-iron and in one piece. It is stiffened with downwardly-projecting ribs 15 and 16, Figs. 10, 10 and 1 3, the rib 16, Fig. 10, being transverse. It is also provided with feet 17, Figs. 1, 8, 10", and 13, which support the keyboard on and are fastened by bolts to the bed-plate 18, Figs. 1, l, 8, 10, and 13. In the top of the keyboard are planed or milled out accurately-spaced parallel transverse recesses 19, Figs. 10, 10, and 13. The recesses have inclined plane bottoms, the lowerparts being toward the front of the keyboard, and their front sides form abutments for the engagement of the key-pawls. The centers of the pivots 7 of the key-pawls being spaced accurately a given distance apart, (in this instance on e in ch theabutmen ts formed by the grooves in the keyboard are accurately spaced to a somewhat greater distance apart, (in this instance one and three thirty-seconds inches,) for a purpose soon to be explained.

The key-slides are arranged on the keyboard in parallel relation and held at equal distances asunder by rib-bars 20, Figs. 1 and 3, and flat plates 21, Figs. 9 and 10. These plates and the rib-bars are held fast by screws, (shown in Fig. 9,) which pass down through both the plates and the rib-bars into tapped holes in the keyboard. The key-slides there fore work in the spaces under the plates 21 and between the rib-bars 20, and the lower edges of their lateral wallsrest and work upon the upper surfaces of the ledges on the top of the keyboard left between the transverse grooves 19. The entire upper surface of the keyboard is planed flat before the grooves are cut to allow the key-slides to bear fairly on IIO all of the ledges so formed. \Yhen so placed .in. position, the front extremities of the keypawls which lie farthest from the front of the keyboard will need to be moved toward the front three thirty-seconds of an inch. to coincide in position with the abutment of the groove farthest from the front. The front extremities of the next row of key-pawls will need to be moved six thirty-seconds of an inch to correspond in position. with the abutment of the next groove, and so on, each transverse row of key-pawls, counting from the .rear row, requiring to be moved three thirty-seconds of an inch farther than the next preceding row.

To move a key-slide toward the front, the operator places the ball of a finger on the rear face of one of the key-buttons and presses thereon toward the front of the keyboard. This pressure tilts the key toward the front and draws the slide in the same direction till the front extremity of the pawl brings up against the abutment in the corresponding groove next toward the front, and thus limits the movement of the slide. As soon as the pressure of the finger is removed from the key-button the key-pawl. spring 11, Fig. 11, restores the original position to the key-pawl and disengages it from its abutment in the groove on the keyboard, as shown in Fig. 11.

To restore the key-slides bodily to their first positions, after they have been operated as described, each one of them is provided with a spring 22, Fig. 10, connected by a hook formed on one end in an eye in the transverse rib 16, and by a similar hook at the opposite end to an eye attached to the ex tension or tang 3 of the key-slide. A hole 23 is drilled through the front part of the keyboard, which permits the necessary extension of the spring toward the front in operating the key-slide. 3y unhooking the springs any one of thekey-slides and its entire mechanism may be withdrawn from the keyboard, as may be necessary for cleaning or replacement of worn parts. The pivots of the keypawls are kept in place when the key-slides are in place by the abutment of their ends against the rib-bars 20, and when a key slide is drawn out any of its keys may be detached by pushing out the key-pawl pivot and the key-socket pin. Thus the key-pawl springs may be replaced and other parts substituted with great facility. The comparatively slow motion of the drop-slides, hereinafter described, requires, however, that the key-slides, when drawn toward the front, should, notwithstanding the tension of the springs 22, be held in the position to which they are drawn until the drop-slides have time to fall to their respective positions, and for this (and for other purposes hereinafter set forth) the steel blocks 4:, at the ends of the slides opposite the ends which carry the tangs 3, are constructed as shown in Fig. 12,

which; is a plan view, and in side elevation in Fig. 1 5. The construction is also partly shown in Fig. 10.

The key-slides are three-fen rths of an inch in width in plan, and the blocks it are milled oft equally on each side, leaving a thickness of three-eighths of an inch in plan at 2t from a point near the place where they are joined by rivets to the body of the key-slide. A corresponding tongue 20 is formed on the body of each key-slide, extending over and upon the steel block 1, as shown in Figs. 12 and 12", through which one of the rivets 25 passes. At the extremity of the block is an upward, flat-topped, case-hardened projection 28, upon which the drop-slide falls, as hereinafter described, and on the under surface of the block is cut a ratchet 2!), Figs. 10 and 1 the teeth of which have in this case a pitch of three thirty-seconds of an inch, or in any case a distance corresponding to the unit distance of motion of the key-slide, or the distance the key-slide can be moved by the key whose finger-button has marked on it the figure 1. (Shown in Fig. 9.) Under each rib-bar 20 there is, on the under side of the keyboard 14, one of thelongitiulinal strengthening-ribs 15, and to this is pivoted a gravitypawl 30, Figs. 10 and 13, (which may, however, be a spring-pawl, if desired,) that engages with the ratchet 22) in. the corresyxnnling keyslide and holds the latter in any position to which, by operating any one of its keys, it can be drawn forward by the operator, and until such time as it is automatically released in a manner hereinafter explained.

The drop-slide mechanism above alluded to is constructed substantially as follows: That margin of the keyboard farthest from the front side is constructed. as shown in Figs. 5), 10, 13, 10 10, 12, and 12 Fig. 10" is an. enlarged detail plan. Fig. 1.0 is a side elevation showing one of the drop-slide guides mounted on the keyboard, and Fig. 1.2" another dctail plan showing two of the drop slides and their guidesin position. Along the rear margin of the keyboard spaces 31 are milled out, as shown in Figs. 10, 10", 12", 12", and 18, to permit the free vertical movement of the drop-slides. On the solid steps 32, Figs. 10, 10", and 2, between the milled-out spaces, are bolted the drop-slide guides 33, Figs. 1, 14., i), 10, 1o, and12,these guides each having a foot- 31, extending toward the front and bolted to the said steps. The steelv blocks 4:, previously described, when the key-slides 1 are in their normal positions, occupy the position shown in Fig. 12, being wide enough to cover the milled-out spaces 31 in the keyboard and overlapping about three sixtyfourths of an inch beyond the sides of the milled-out spaces 31, thus resting upon and when operated sliding upon the margins of the steps The spaces between the steps also permit the pawls 30, one for each dropslide, to engage with the ratchets 29 whenever the key slides are pulled toward the front, as will be presently further explained.

In one side of each drop-slide guide 33 is formed a groove or guideway 35. (Shown in full outline in Figs. 10 and 10. also shown in plan in Figs. 9 and 12 but are not there numbered for reference.)

The drop-slides are shown at 30, Figs. 1, 9, 10, 10, 12 and 13. One of these drop-slides is arranged in relation with each key-slide. Each drop-slide in the present example of my invention consists of a brass or composition body 36 (best shown in Fig. 10) and a hardened steel step-piece 37, Figs. 10, 10, 12 and 13. The body 36 has longitudinal ribs or splines 38 formed on it, which ribs, being in line with each other, may properly be considered as one rib or spline, parts of which are removed to afford opportunity to rivet the step-plate to the body. The step-plate being cut away half its thickness on the side toward the body, and the body cut away similarly on the side toward the step-plate, the two parts are accurately fitted together and joined by riveting. The step-plate 37 has approximately a rhomboidal form, this being preferred for the reason that as the part of it projecting to the front of the body has its front edge inclined, as shown, the part projecting toward the rear, of similar form reversed, very nearly balances that projecting to the front, thus reducing the friction of the drop-slides when the latter are operated, as hereinafter explained. On the front edge of each step-plate are formed ten steps. (Best shown at 39, Fig. 10.)

In the normal position of the key-slides, which is that shown. in Fig. 10, the lowermost steps of each step-plate rest on the ends of the steel blocks at, as shown. The steps have a uniform horizontal depth equal to the distance to which anyone of the key-slides can be drawn toward the front by operating its key whose button is marked with the figure 1 in Fig. 0. The steps have also a uniform rise of onefourth of an inch in this case. 'When the keyslides are in the normal position, the operation of any key marked with a figure other than 1 moves the corresponding key-slide toward the front through a distance equal to that which operating its 1 key would move it multiplied by the figure marked on the key operated. It follows that when the drop-slides are in normal position the operation of a 1 key will allow the corresponding drop-slide to slide down between its adjacent drop-slides and descend a distance equal to the rise of one step. The operation of a 2 key will let the dropslide fall through a distance equal to the rise of two steps, and so on. Thus in Fig. 13 the parts are shown in full outline in the position when the "t key has been operated, and the corresponding position of the dropslidc after descending shows it to have dropped through a distance of four steps, being arrested from further dropping by the next step They are in order, which now rests upon the steel block -it. Thus by operating the keys as described the drop-slides maybe caused to drop through distances the shorter of which may be called unit distance, and the other distances will be, respectively, multiples of the unit distance or the unit distance multiplied, respectively, by digits indicated on the keys operated. Thus operating the 3 key will allow the drop-slide to fall through three times the unit distance, operating the 5 key will allow the drop-slide to fall through five times the unit distance, and similarly for any key operated. In order that the dropslides may fall freely as far as necessary, a recess 40 is formed in the upper side of the bed-plate 18, as shown in section in Figs. 10 and 13, this recess extending laterally across the bed-plate under all the drop-slides. To the bottom of each of the drop-slides is attached a weight 11, Figs. 7, 10, and 1-3, of lead, composition, or other suitable material, this being preferred rather than to make the drop-slides themselves so heavy as to look unsightly; but these weights might be omitted without in any wise affecting the principle of action or the function of the dropslides, as the drop-slides can be made heavy enough without the weights by sacrificing to some extent the appearance of lightness in the machine, or springs may replace the weights.

Projecting toward the front from the lower part of each drop-slide is a toe or tappet -12, Figs. 10, 10, and 13, which, when any dropslide is in the normal position and supported by the part 28 of the steel block 4., as shown in Fig. 10 and also in dotted outline in Fig. 13, engages the rear part of the corresponding gravity pawl 30 and disengages the latter from the ratchet 29 in the bottom of the steel block. The lifting of any or all of the dropslides up to the normal position after their fall therefore automatically releases the corresponding key-slide or key-slides from the gravity pawl or pawls which have previously held them from returning to their normal po sition, and then the tension of the springs 22 immediately causes them to return to the normal position. Their return brings the parts 28 of the steel. blocks i into engagement with the lower steps of the step-plates 37 on the drop-slides, and thus holds them from again falling until the operator again draws the keyslides toward the front. In the regular operation of the machine all the drop-slides which have been permitted to drop by the manipulation of the keys are lifted simultaneously by means of a lifting-bar,yet to be described; but provision is also made for lifting any one of them at will. This is done by means of a flexible strip of steel, German silver, or other suitable material attached to the upper part of the step-plate of each drop-slide, as shown at 13, Figs. 3, 10, and 13.

I have shown. the machine as without the casing which incloses the drop-slides and register, this being no part of the invention; but when this is put on the upper ends of the lifting-strips l just described, extend up ward through the top of the case, and are formed at their upper extremities into a small scroll for conveniently grasping them with the fingers. Thus, if the operator has drawn out any of the keyslides and has thus permitted the corresponding drop-slide to fall, he may, if desired, restore the drop-slide independently by lifting the drop-slide back to its normal position through the aid of the flexible lifting-strip attached to its step-plate,as described. This releases the key-slide correlated with the drop-slide, ashereinbefore described, and permits the key-slide also to return to normal position. The flexible strips also perform the function of indicators which. show whether in setting the printin mechanism any error has been committed. The front face of each of the strips is enameled. white, and on each of them, except those at the left, this surface has printed on it the ten Arabic numerals in order, beginning with the Zero at the bottom and making the next figure above this 1, the next above 1, 2, and so on till 0 isincluded. A vertical flat plate all, Figs. 1 and 3, is supported directly in front of the lifting-strips by having its outermost right and left margins bent at right angles backward, and respectively attached by screws to the extreme right and extreme left drop-slide guide. In this indicator-plate are cut holes 1-5, situated one of them directly in front of each flexible liftingstrip l3, and in such manner that when any dropslide is in its normal position the Zero figure marked on each strip, except the three on the left hand, shows through the corresponding aperture.

The figures on the front faces of the strips are spaced vertically, each from the next one above it, a distance equal to the rise of one of the steps 35) in the step-plates 37. Therefore, if the lower step of the drop-slide step- PlHlLGSflVllOSQ lifting-strips are printed, as described, be considered as the zero position, the zero marked on the strips will be seen through the holes. If any of the drop-slides whose lifting-strips are so marked be permitted to drop through a distance of one step, the figures ll. on. such lifting-strips will show. If they drop through a distance of two steps, their figures 2 will show, and so on. The figures on the lifiii'ig-strips, therefore, always indicate the number of steps through whose total vertical distance the drop-slides have moved, and as this distance must correspond, as already has been explained, with the key operated on the corresponding key-slide, it follows that if the wrong figure shows at the corresponding hole in the iin'lieator-plate the wrong key has been operated. The operator may then at once correct this error by lifting the drop-slide into normal position, when the key-slide will auton'iatically resume the normal position. It then can be set again to the correct position, and these operations affect no part of the machine except the mechanism directly connected with and positively operated by the drop-slide so manipulated. The lifting-strips of the three drop-slides at the left side, or the tenth, eleventh, and twelfth drop-slides, counting from the right of the entire set when standing in front of the machine, are printed differently from the others, each of these three strips having eleven characters. The lowest character is an asterisk. The next above it is the figure l the next above this 2, and so on upward in the usual order of the digits, the uppermost being the zero figure. These characters are spaced along the lifting-strips at the same distance from each other, as described for the other liftingstrips. It follows that when the drop-slides to which the strips having asterisks on them are attached are brought to their normal positions asterisks instead of Zero figures will show through the corresponding apertures in. the imlieator- 'ilate ii. The purpose of this arrangement is explained hereinafter.

It will be seen on inspection of Fig. 5) that the key-slides corresponding with the tenth, eleventh, and twelfth drop-slides (counting from the .right when standing in front of the machine) each have one more key than the others countedin the same way up to and .incl udin g the ninth key-slide. The explanation of this arrangement will also be given hereinafter.

It is one of the functions of the d rep-slides to so control the printing mechanism,next to be described, that the latter shall print upon the depositors pass-book a portion of the characters indicated at the apertures 45 of the indicator-plate ii, and also print them sin'uiltaneously with printing the pass-book upon a concealed tape, hereinbeforc mentioned, upon which tape the characters not printed in the pass-book are also printed. A second function of the drop-slides is to control the action of the registering or adding mechanism. in such manner as to cause the latter to add to the total previouslyindicated. by this mechanism the sum of money ind icated by the imprint upon the pass-book, and to do this before any other printing can be done either upon the pass-book or upon the tape. To accomplish the first of these functions, each drop-slide has at the top a rearward projection l0, Figs. 0, 10, 10, and 13, and this projection on each of the dropslides is connected by a link 47, Figs. 10 and 13, to an internally-toothed gear 4:8, Figs. 1,l,10, l3, and 16. The construction of these internally-toothed gears (one for each drop-slide) is shown more particularly in detail in Fig. 16, which is a vertical section through the axis of the gear and the four-armed spider on which it is supported. On each. side of each gear is a laterally-projecting rim 4:1), Figs. 10, 12:3, and 10. Vfithin this rim and extending farther toward the center is the toothed part 50 of the gear, as shown in Figs. l0, l3, and 16. Outside of the rim t?) the i11ternally-toothed gear extends away from the center, forming IIO an annular projection 51, to which the link 47 is pivoted, as shown in Figs. 1, 10, and 13. This construction of the gear-wheel gives it not only great rigidity, but also gives it sufficient weight to prevent its acquiring a too high. velocity when actuated by its correlated dropslide through the medium of link 47, and this is the chief purpose which the annular projections 51 of the gears are intended to subserve. "Were the drop-slides not resisted in their fall by the inertia of the gears, they would strike too hard blows when their fall is arrested by the steel blocks 4 of the key-slides, and thus would be noisy, and the step-plates would also wear more rapidly. \Vith the construction described the fall of the drop-slides is much slower than if their motion were not opposed by the inertia of the connected wheels, and the arrest of their motion by the steel blocks 4 makes very little noise. The use of heavier or lighter weights 41 on the drop-slides enables the force of gravity and the inertia of the wheels to be counterbalanced so far as to secure the action described to any degree of nicety.

A bar or dead-spindle 52, Figs. 1, 4, 8, E), 10, and 13 is supported by posts 53, Figs. 1, 4, 8, 9, 10, and 13. The dead-spindle 52 is fitted to holes in the upper parts of the posts 53 and is held in fixed relation with the posts by pins (not shown) which are inserted transversely through the tops of the posts and the extremities of the dead-spindle. The posts are bolted to the bed-plate 18 in such positions that the dead-spindle extends transversely over the upper face of the bed-plate and behind the drop-slides at such distance that when the links 47 are connected with the wheels that are concentric with the spindle, and when they are also connected with the rearward projections of the drop-slides, they assume nearly a vertical position when all the other parts are in the normal position, as indicated in Fig. 10. \Vhen the dropslides fall in operating the machine, the links are only slightly inclined from the vertical position, the are described by the pin that connects them with the wheels being quite small.

On the dead-spindle are keyed the fourarined spiders 54, Figs. 10, 13, and 16. There is one of these spiders for each of the internally-toothed wheels 48. Each of the spiders has a hub 55, Fig. 16, fitted to the deadspindle 52 and held in rigid relation with the spindle by a key-pin driven through a hole 56 in the hub, (shown in Fig. 16,) and also through a corresponding hole in the deadspindle. Three of the arms on each spider include angles of one hundred and twenty degrees between their radial axes, and have at their extremities hubs 57, Figs. 13 and 16. Stud-pin bearings 58, Figs. 13 and 16, project laterally at right angles from the hubs 57, as shown in Fig. 16, and on these stud-pin bearings are fitted rollers 59, Figs. 13 and 16. Each of these rollers has two flanges 66, Fig.

16, and the inner margin of the flanges is shouldered down in such manner that when the parts are assembled and the rollers are mounted on the screw stud-pin bearings the inner face of the rim 49 of the internallytoothed wheel bears against the perimeters of the inner parts of the roller-flanges, as shown in Fig. 16, while the outer parts of said flanges project somewhat beyond the inner margins of the rim 40, the width of the rim being such as to afford an easy-working fit between the projecting flanges. The rollers are of uniform size, and the screw stud-pins are accurately centered at equal radial distances from the axis of the dead-spindle in such manner that when the parts are assembled the rim 49 of the internally-toothed gear-wheel is held. in a position concentric with the axis of the dead-spindle. The middle part 59 of each roller is turned down, so as to allow clearance between the crowns of the teeth in the gears 48 and the exterior of said middle parts of the rollers. Vhen the parts of this mechanism are assembled,the wheels 48 turn freely and concentrically with the axis of the deadspindle 52 through any are corresponding to the motion of the connected drop-slide.

The fourth arm 61, Figs. 10 and 13, is placed at an angle, respectively, of forty-five degrees and seventy-five degrees from the radial axis of two of the spider-arms carrying the rollers 59. In the outer part of each arm 61 is formed a bearing for one of the shafts 62, Figs. 1, 4, 8, f), 13, 15, and 16. Ends of these shafts are also shown in Fig. 10, but are not numbered on that figure. The extremities of the shafts 62 opposite to those which have bearings in the hubs of the arms of the spiders 54 have bearings 63 in the web 64 of the printing-head, yet to be described, as shown in Figs. 4, 7, S, and 15. The shafts being shouldered, these shoulders abut against the inner faces of the hubs on the arms 61, Fig. 13, and also against the face of the web 64, Figs. 4, S, and 15, and this prevents their moving longitudinally. The shafts 62 have free rotary movement in their bearings when actuated in the manner soon to be described. On each shaft 62, near its bearing in its proper spider-arm, is a pinion 65, Figs. 10 and 13, which meshes into the correlated internally toothed gear which drives it. Each of the shafts 62 has mounted upon it a spur-gear 66, Fig. 15. These gears are preferably made with hubs 67 extending to the right beyond the margin of the shell of the printing-head far enough to admit of their being rigidly attached to their respective shafts by keypins 68, Fig. 15, and in proper positions to perform a function hereinafter explained.

The printing-head above spoken of consists of a cylindrical shell 69, Figs. 4, 8, and 15, formed integrally with a web 64, Fig. 15, and a hub 70, Fig. 15, by which latter it is supported by the dead-spindle 52, being rigidly attached to said spindle by a pin 71. It

comprises typerings or type-wheels for printing, elick-s n'ings for holding certain. of these rings when set for printing any particular date, mechanism for holding the type-rings in proper lateral adjustment, bearings for the shafts (52, already described, and two fixed but detachable rings forholdin g the movable rings upon the outer surface of the cylindrical shell, which is their bearing. The movable printing-rings all slide circumterentially upon the outer surface of the shell when they are moved about the axis of the deadspindle, ashereinafter described. These rings are shown but not numbered in Figs. 1 and 9. In Fig. 15 they are shown in section on a scale nearly full size and numbered for reference. There are three groups of printing-rings supported on the printing-head shell. This shell. has a peripheral rib 72, Fig. 15, formed integrally with and extending entirely around the outer surface of the shell. The four rings numbered 73 H- 76 in Fig. 15 constitute one group. ()n the ring '73 are engraved. ordinal numbers respectively representing the days of the month, l, 2, :3, the, up to and including 31.. On the ring Tl are engraved the names of all the months in the year. On the ring 75 are engraved the figures representing the year, beginning with, say, 1895, and following successively with 1890, and so on, for as many succeeding years as itmay be desirable to represent on the ring. On the periphery of the ring 76 is engraved the word Recd, several times repeated in different positions, and also the word Paid, several timesrepeated. Theobjeetincngravingthese words in dili'erent positions and several times upon the ring is, first, to enable either the word Recd or Paid to be used, according as the machine is to be used by the receivin g-teller or the paying-teller, and, second, there being more than one set of engraved types for printing each word, should any one set get worn another can be brought into position for printing. Thus this ring can be made to last much longer in use than though the words to be printed were only once represented thereon. This group of printing-rings, each of which may be rotated upon the outer surface of the printing-head. shell, is held laterally by the rib '72 on the right of it and by the fixed ring 77, fitted to the left-hand margin of the shell and there attached by screws (not shown) inserted radially through the ring and penetrating the shell. Attached to the inside of the shell by rivets are click-springs 7S 7.) 8O 81, Figs. i, S, and 15. Holes are cut through the shell, as indicated in dotted out line in Figs. 4c and 8, which allow bits formed on the points of each. of these click-springs to pass through the shell and engage V- shaped nicks on the interior surface of the printing-ring 72 74-, 75,01 76 with which it is correlated. The ring '73 has thirty-one of these V-shaped notches; the ring 7st has twelve of them; the ring 75 has a number of them corresponding to the number of years indicated thereon, and, the rin 76 has as many of these notches as the number of the words l'tecd and Paid engraved upon it. The click-springs hold the rings of this group with sullicient firmness to prevent their turning in the operation of printing, but not so rigidly as to prevent their being turned to any desired or required position by the hand of the operator applied to their exterior surfaces. They can thus be set to print the hereinbefiire-described form of record for any date in any year within the scope of the ring 75.

Another group of seven printing-rings, counting toward. the right hand from the rib 72 on the printing-head, are those used for printing amounts deposited, and they are IGSPGCi'iYOl)" numbered 82, 8:3, 84:, S5, 86, 67, and So in Fig. 15. These rings are each formed with internal teeth 85, Fig. 1.5, the crowns ot' the teeth being made to bear upon the exterior of the printing-head shell, and slots 85), one slot for each s nir-gear, are cut through the shell, which allows a portion of the teeth on each spur-gear (36 to pass through. the shell and mesh with the corresponding superimposed printing-ring. The front part of the printing-head being cut away in Fig. 15, only one of the gears (36, which respectively move each one of the rings ot' this particular group, is shown in the figure; but the order of their arrangement will be more fully understood by the aid of the following description of a third group of six printingrings,separated from the last-described group by an annular space 00, Fig. 15, and operated in the same way. This third group of rings are those used to print the number of the pass-book on the concealed tape, yet to be described. They are numbered 011., 92, 93, til, 05, and in Fig. 15, and, except in respect of the arrangement of types engraved on their perimeter, they are exactly like the rings of the second group, previously described. The internal teeth on each ring mesh with the underlying gear 66, which actuates the particular ring. The shafts 62 are arranged at equal radial distances from the axis of the dead-spindle 52, and the rings are arranged in planes at equal lateral distances from each other. A regular curve drawn through the axes of the wheels and intersecting their middle vertical planes would be a helix. The arrangement of the wheels 66, which actuate the rings of the group that prints amounts deposited, and which wheels are in the part of the head cut away in Fig. 15, is preeisel y analogous to that described for the group of rings which print the number of the pass-book.

Each of the rings so to 88, inclusive, has engraved in relief on its perimeter two sets of Arabic figures, to wit, in each set the nine digits and the cipher, each set being in the order (C0777 41777 (2 7) 43777 (42777 (5, 7 (C 0777 Li 7777 (4 87 9. Each figure of each set of types thus engraved is arranged on the perimeter of each ring of this group at a point diametrically opposite the same figure in the other set on the same ring. Thus the type for the figure 1 in one set is opposite the figure 1 in the other set of figures on the same ring, the figure 2 in one set is opposite the figure 2 in the other set of figures on the same ring, and so on for all the figures. The surfaces of the pass-book page and of the concealed tape being presented to the printing-wheels of this group at diametrically opposite points and being pressed simultaneously against the types on the printing-wheels in that position,as herein after explained, it follows that the book cannot be printed without printing the tape, and that if either be printed the other must also be printed, each with the same amount. The ring 82 has engraved on its perimeter twenty of the signs indicating dollars is) spaced asunder exactly like the figures on the adjacent ring 83. Stud-pins 97 project laterally from the ring 83, and, entering holes in the ring 82, compel these two rings to move to getherthat is to say, whenever the ring 83 is moved by the mechanism described, the ring 82 is also moved with it and brings one of the dollar signs into position for printing. The ring 82 might, however, be a fixed ring having only two dollar signs engraved oppositely upon it and set so that these would always print when the machine is operated for printing; but making it movable and distributing the wear upon twenty instead of two of these types is preferred. The rings 83 Sat 85 of the second group have each engraved thereon one set of the natural series of cardinal Arabic numbers or figures in the order ure 1. These figures are arranged in such manner that the figures will be brought into position for printing in due order by operating the correlated key-slides by the use of the keys successively from 1to 0,inclusive. In their normal position the zero figures on the rings 86 87 88 and on all the rings of the third group are presented to the tape and pass-book for printing, and in the normal position the asterisks on the rings 83 81 85 are presented. llence in printing one or more zeros by the rings 86, S7, and 88 only the drop-slides corresponding to significant figures need be operated. Thus, were it required to print the number 900,009 of a pass-book, only the 9 -key on the key-slide connected intermediately with the ring 91 and the 9 -key on the key-slide connected intermediately with the ring 96 would need to be operated to arrange the group to print that number. If the number 0,010 of a pass-book were required to be printed, the 9 -key on the key-slide intermediately connected with the ring 03 and the 1 -key on the key-slide intermediately connected with the ring would be all that need be manipulated. This construction, which makes the zeros print without manipulation, is the same for all of the rings, except 82, 83, and 8.4, which have each eleven characters to print, as will be presently further explained, and which do not print zero in their normal position. The manipulation of the keys is simplified by making the zeros print in the normal position, but for the three keys named as exceptions this advantage is sacrificed to carry out another purpose yet to be described.

The rings are kept properly spaced from each other by combs 98, Figs. 1, 4, 8, 9, and 15, in which latter figure one of the combs is shown as in a position not corresponding with its position on the other figures for the purpose of showing the comb-teeth, which enter between the rings and hold them separated and in their proper positions. The combs are preferably three in number, and when this number is used they are placed one hundred and twenty degrees apart and fastened by screws at one end to the rib 72 and at the other end to a fixed ring 99, Fig. 15. The function of the latter, besides forming a support for the combs, is to form a lateral facebearing for the ring 96.

The rings 83 Si 85 have engraved upon them in relief an asterisk, succeeded by the (1777 {C 2777 (4:) 77 (6%, (5,77 ((6 77 (7,77 8, 0, 0, and are so set that the asterisk prints in the normal position. The keyslides correspoiuling with these rings have each ten keys, one for each of the significant figures and one for the zero. None of the other key-slides has a zero-key. The manipulation of the key-slides intermediately connected with the rings that print asterisks is the same as that of the others, with the exception that the others need not be operated to print zeros. In printing, the figures presented 'at the bottom of the rings print the pass-book and those presented at the top print the tape.

The printing mechanism will now be described.

In proper relation with the printing-head are screwed into the bed-plate four stout guide-rods .100, Figs. 1, 4, S, and 9. A carriage 101, Figs. 1, i, and 8, slides vertically on these guide rods or posts and carries the platen 103 for holding the pass-book to be printed. The carriage has at each of its four corners a sleevebearing 102, Figs. 1, 4, S, and 9, fitted to the guide-posts in such manner that it may move up or down parallel to itself in all parts of its motion. The top of this carriage is faced off to form a sliding bearing for the platen 103, Figs. 4, S, and 0, which is supported by and moves up and down with the carriage. The under side of this platen is planed to fit the upper face of the carriage and to slide thereon, as yet to be described. The platen is of considerably greater length than the carriage, and at each end it has a descending projection 1041, Figs. 1 and at. A rod 105, Figs. 1 and 4, is passed through holes bored in line through the downward projections 011 the platen and through the body of the carriage, and is then fastened IIO receiving the book, that during this latter rigidly to the downward projections by a keypin at one end and a screw-thread and nut on the other, the latter being shown but not nunr bered in Fl 1. Th e rod is fitted to slide easily in the hole bored through the body of the carriage, and this permits the platen to be drawn toward the front to receive the pass-book to be printed and again slid back to the position shown in Figs. at and 1'), which is the position for printing. The distance to which it can thus be drawn forward is limited by the abut ment of the rearward downward projection 101 againstlhe rear of the carriage. (Shown in dotted. outline in Fig. \Yhen slid into the position for printing, the motion is also limited by the abutment of the front downward projection 101 against the front of the carriage.

The inking mechanism is attached to and carried by the platen. Attached by screws to opposite sides of the platen are curved s u pports of steel, 1.06, Figs. .4. and .l. In the upper parts of these supports are bearings for a rock-shaft 107, to which are attached the rock-levers 108. (Also shown but not numbered on Fig. 1.) These levers rock with the rock-sh aft, and thus move simultaneously and equally when actuated, as will presently be explained. A spring 101), Figsi and. .1, is attached to one of the curved uprights (in this instance the inner one) and also to the nearest of the pair of rock-levers 108 at a point in advance of the rock-shaft. The action of this sprin is to press this pair of rocklevers downward toward the typc-rin gs of the printing-head. The motion this produces is limited by an adj ustable screw-slop consisting of a bracket 110, 1, riveted or otherwise fastened to and proj eciing forward from one of the curved supports 106 at alittle distance below the rock-shaft, and a screw 111, Fig. 1, fitted into the front end of the bracket, upon which screw the under surface of the rock-lever on that side rests when in its lowest position. lYhile the downward motion of the pair of rock-leversis thus limited, the upward motion against the action of the springs is free within the extent which the spring will permit. In the front parts of this pair of rock-levers arebearin for the spindle of an ink-roller 11), Figs. 1, 1, and i), which inks the types brought to the upper position at the time when the platen .103 is being pushed backward into the printing position.

It is desirable that the inking shall be con fined to the types that are to be printed from innnediately, and as in the general operation of the machine the types are brought into position before the platen 10b is pushed back to the position for printing, it is necessary, in order to prevent inking types when the platen is pulled forward to the position for motion the inking-rolls shall be held away from the types. To effect this, a spring-d i g 111, Fig. 4e, is attached to the spindle of the ink-roller and so constructed and adjusted that when the platen and its attachments are pulled toward the front the dog slides upon the top of the iixed ring 90, Fig. 15, and pnshesthe ink-rollawayfrom thetype. From the rear side of said dog 111, Figs. 5 and o, projects a small arm 111-, whose motion is limited by the stop-pin 1143, inserted in the side of the rocker-arm. 108, to which the inkroller is pivoted. The dog rocks freely on the journal of the ink-roller. The arm 114; is engaged. by a wire spring 111" and pressed toward the stop-pin 111 against which said arm abuts at all times except when the inkroller is passing over the types in the direction indicated by the arrow in Fig. (.3. When moving inthe opposite direction, which it does when the platen is moving forward into the position for taking out the book just printed. and for receiving another book 10 be printed, the dog 11.1 takes the position shown in Fig. 5, holding the inking-roll away from. the types, over which it passes without inking them. The inking is, therefore, performed only during the rearward movement of the platen. I do not confine myself to any particular way of fastening the spring 114;" to the rocker-arm 108; but in this instance I have used pins 111, around which. the spring is coiled, as shown in both Figs. 5 and (.3. The construction of the dog, spring, and stop on the lower rocker-arm118 of the lower inkroller 115, Fig. 5, is substantially the same described for these parts on the rocker-arm 108 in Fig. (.3, and therefore needs no further description. \Vhen the platen is pushed back into the position for printing, this dog, being free to swing toward the front, does not push the roll away, but permits it to roll over the surface of the types and ink them. This ink-roll 112, as also another one yet to be described, is made of felt, and is charged with good stamping-inkthat is, ink of the kind used in stamping figures and dates upon checks, documents, &c., with metal types. The lower types are inked by the ink-roll 115, Fig. '-l-, which. is mounted on rock-levers 118 exactly like the roll112, and has a springdog 11G exactly like that described for roll 112, which holds the roll away from the types when the platen is pulled forward. It also has an adjustable step 117, Fig. 1:, like that marked 110 and 111 in the same figure and already described. As the motion of this pair of rock-levers when pushed away from the types by the dog is in an ODPOSllEO direction'from that of the upper pair, both the dog 110 and the step 117 have their position reversed as compared with the positions of the dog 11 r and the step 110 and 111. The spring which rocks the levers 11S toward the types is, however, differently attached. The enter one of this pair has a rearward extension 110, with an eyehole into which the spring 121 being hooked, the latter is also hooked at the other end onto a pin 1.20 inserted into the rear end of the platen.

From the front end of the platen project two opposite lugs 122, Figs. 1, 1, and 9, to which is attached a handle 123, of suitable material, as wood, bone, or ivory, which the operator grasps in sliding in or pulling out the platen when operating the machine.

To the left longitudinal margin of the upper face of the platen is attached, by screws, rivets, or brazing, a straight metal rib or guide 12%, Figs. 4 and 9, against which the left edge of the pass-book is made to bear when printing. This insures accurate horizontal alinement on the page of the printed dates and figures representing amounts deposited. There are also curved spring-plates attached to the upper face of the platen, which perform the double function of holding the book to be printed firmly down upon the platen and also of gages for position, which enables the operator to quickly, yet with sufficient accuracy, place the book in the proper position to secure the needed uniformity of spaces between the successively printed lines. One of these springs 125, Figs. a and 0, is attached by screws to an upward projection 126, Fig. 9, formed on the platen, and it extends toward the front from the line of types that print to a distance equal to the desired distance between the printed lines after they are printed, so that when the book is placed on the platen, if the last printed line be pushed under the spring till it is just hidden from view, the next line printed will be at the proper uniform distance from the last one previously printed. Near the front end of the platen are bolted two brackets 127, Figs. 1, at, and 9, to the rear faces of which are attached the bent spring-plate 128, Figs. 1, 4, and 9, the rear margin of which presses downward upon the platen or upon the book when slid under it upon the platen. The rear edge of this plate is placed at a distance from the front edge of the plate 125 equal to twice the desired distance or space between the printed lines. If, therefore, the pages of the book be ruled with uniform distances between the ruled lines equal to the desired distances between the printed lines, and the book to be printed. be slid under the plate 128 till the line next below where it is desired to print is brought flush with the rear edge of the plate, the book will be in the proper position for printing, provided its left margin be also pressed against the longitudinal guide 124, previously described. It will be more convenient to call these spring-plates book-holders in further referring to them. The inner or right-hand corner of the front edge of the rear bookholder 125 and the right-hand corner of the rear edge of the front book-holder are bent upward a little, so that these corners do not bear upon the platen. hen, therefore, the platen is drawn toward the front as far as it can be, the operator, holding the pass-book in his right hand by its .right margin, can. with a single movement slide the book under the book-holders, and almost simultaneously bring the book into position for printing.

After printing, the platen being pulled toward. the front as far as it can be, the operator takes hold of the book at its right-hand margin with his right hand and slips the book out toward the right, and then may hand it immediately to the depositor.

I have found that the front book-holder is alone sufficient both as guide and holder. The printing is, however, perhaps somewhat more perfect when both are used, and hence it is preferred to use both.

The carriage 101, upon which the platen 103 slides, has downwardly-projeeting lugs 11 3, Figs. 1, a, and 8. A link 130, pivoted to the lugs 113, connects the platen with the front end of a rock-lever 129, Figs 4 and 8, to which the link 130 is also pivoted. \Vhen the rock-lever is operated as hereinafter described, it operates the carriage to move it and the platen supported by it toward and away from the types for printing the passbook. A similar rock-lever 131, Figs. 4 and 8, carries the tape-box 132 and its mechanism. (Shown in the same figures.)

The body of th e tapebox is preferably made of a single piece of cast-iron with downwardly-projecting sliding bearings 133, Figs. 1, 4, 4L, and 8, fitted to slide on the guideposts 100 in the same way as described for the sliding bearings of the platen-carriage. These sliding bearings are connected by a plate 134, Fig. 4;, cast in one piece with the sliding bearings, which plate forms the bottom of the tape-box. 011 the upper side of this plate are cast in one piece with the plate three sides of a rectangular box. The upper part of this box is, when in use, covered partly by a plate 135, Figs. 4 and at, which extends toward the front a little way, and the rest is covered and closed by a detachable metal cover 136. (Shown in side elevation in Figs. at and 8, and partly broken away in Fig. 1 to show the interior from the front.) Fig. 4: represents the tape-box with the cover removed in order to show the spools which carry the tape and the mechanism in the box. for feeding along the tape when it is printed. From the rear of the box extend continuations 137 of the sides to the rear sliding sleeve-bearings. Between these continuations are cast on the plate lugs 138, Figs. 4, at, and 8, to which a link 139 is pivoted. This link is also pivoted to the rock-lever 131, which moves the entire box and its appurtenances up and down in printing the tape.

The cover 130 is accurately fitted to the front edges and top edges of the sides 132 of the box, and the back edge of the cover is fitted into a groove out under the solid part 135, as shown in Figs. 4L and 8 at 140. The front part of the cover is also closely fitted to the front projecting part of the plate 131. A hole is bored through both the cover and the plate at this front part, and a bolt 1&1, Figs. a and 1 is inserted through the bottom of the tape-box, as shown in Fig. l.
