CASH INDICATING, RECORDING, AND REGISTERING MACHINE.
$1 ECIFICATION forming part of Letters Patent No. 447,636, dated February 21, 1891.
Application filed February 19, 1890. Serial No. 341,016, (No niodeld To (tZZ whom it may conceive.-
Beit known that I, CARL lV. WErss, cf the city, county, and State of New York, have invented certain new and useful Improvements in Cash Indieating,Rec rding, and Register ing Machines; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to letters and figures of reference marked thereon, making a part of this specification- My invention relates to that class of machines for indicating, recording, and registering cash payments which are operated by a crank, and has for its object to provide a simple, compact, efficient cash machine at a low cost.
It consists in the combination and arrangement of the several mechanical devices, substantially as is hereinafter described and claimed.
In the accompanying drawings, Figure l is a rear view of the machine with its outer casing removed; Fig. 2, a transverse section in line [C x of Fig. 1 with certain portions thereof broken away to exhibit the underlying mechanism; Fig. 3, a detail illustrating the movement of the carrying-pawl by which the adding mechanism is actuated; Fig. 4-, a transverse section in line 1] y of Fig. 1, illustrating the movements of the printingmech anism; Fig. 5, a transverse section in line of Fig. 1, illustrating the double-acting pawl controlling the movement of the main crankshaft, and Figs. 0 and T, detailed views, partly in section illustrating modifications of the invention.
Similar letters and numerals indicate like parts in all of the figures.
A represents the bed-plate, and B B the vertical end plates of the machine firmly secured to said bed-plate.
C is a shaft extending parallel with the bedplate and rotating in suitable bearings in the two end plates B 3. An indicating disk or wheel I) (see Figs. 1 and "2) is fixed upon one end of said shaft to revolve with it, preferably outside of the
proxii'natc end plate 13.
' The figures representing the several denominations of the cash payments to be registered and recorded are marked upon said indicating-wheel, preferably upon its rim, as shown in Figs. 2 and l, and the wheelis'incased so that but one denomination shall be brought to view at a time through a suitable sightopening E E, formed in the casing on each side of the disk. A printing-wheel F, (see Figs. 1 and 4,) bearing type corresponding with the numbers upon the indicating-wheel D, is also fixed upon that end of the shaft 0 which is proximate to the indicating-disk, and the train of numbering-wheels G G G G in the adding mechanism is mounted to revolve loosely upon the same shaft. The shaft 0 is turned to set the indicating and printing wheels by means of a milled wheel 0, fitted on the extremity of its opposite end outside of the end plate 13'. (See Fig. 1.)
The units-wheel G in the train of addingwheels is preferably placed next to the printing-wheel F. It is formed with a lateral ratchet-wheel 3F, having a concentric flange ll projecting therefrom toward the printingwheel F, the ratchet-wheel and its flange being made integral with said units-wheel or made fast thereto, as shown in Fig. 1.
A wheel I, of a diameter exceeding that of the flange ll ,is mounted to revolve loosely on the shaft between the flange and the print ing-wheel, and is geared by means of a toothed wheel J (see Fig. 1) to a driving-pinion J, fixed on a lower shaft K, mounted parallel with the shaft C, to rotate in the end plates B B of the maehine,this shaft K being actu ated by a crank K on its outer end.
A pawl a is pivoted loosely to the side of the wheel I in a manner to overhang and drop into contact with the periphery of the flange II, and its contact is enforced by means of a spring I). (See Fig. 2.) The flange H serves as a carriage for a series of clutch-pins c 'c 0, corresponding in number with the figures on the indicatingwheel D and the printing-wheel F, said pins being inserted radially through openings in the periphery of the flange to play longitudinally therein, their inner ends being supported by a second annularconcentric flange ll, (see Fig. 2,) secured to or formed integrally with the units-wheel G to encircle the axial shaft 0 at a short distance radially therefrom. The outer end of each pin 0 terminates in ahead, (see-Fig. 2,) which prevents it from dropping inward, this head being so rounded off as to allow the pawl a to slide freely over it when the pin is carried inward into its normal position, with its head in contact with the peripheral surface of the annular flange or carriage H. When in this posi-' tion the inner end of each pin 0 projects slightly through the second annular flange H toward the shaft 0. The several pins 0 c c are automatically carried inwardly and held in their normal position bymeans of a spiral spring encircling each betweeirthe outer and inner flanges H H, as shown in Fig. 2.
A lug dis fitted (see Fig. 2) to project from the periphery of the shaft 0 in register with the inner ends of the clutch-pins c c a, so as to push them out as in the rotation of the shaft it is in turn brought into contact with each. As these pins correspond severally with the numbers on the indicating-wheel D, secured to the shaft 0, it follows that when the shaft is turned to bring any one of the numbers on said wheel to the sight-openings E the lug cl will force outward the corresponding clutch-pine, so that the head of the pin will project beyond the periphery of the carriage H far enough to engage the pawl a.
as; it is carried around and over the face of said carriage, and when this engagement takes place the carriage will be made to revolve with the pawl in unison with the wheel I, carrying said pawl.
The forward movement of the wheel I is positively arrested so soon as it has made a single revolution by means of an arm or detent L, so pivoted upon the crank-shaft K as to admit of swinging into contact with the periphery of the carriage H in advance of the pawl a to stop it. This arm L is made to revolve with the crank-shaft K by means of a spring-act uated f riction-block 6, (see Fig. 3,), playing against. the shaft in arecess in the collar f, from which the arm projects, the pressure of the block e being adjusted Joy means of a set-screw g, or, as an equivalent, by means of an adjustable elastic disk 6, made to bear against the end of the collar f, as shown in Fig. 7.. The movement of said arm L in unison with the shaft K is arrested before it comes into contact with the carriage H by means of a lateral projection L on the arm L, (see Fig. 1,) which will bear against. the periphery of the wheel I. At the proper moment for arresting the movement of the carriage H a recess M (see Fig. 2) cut in the periphery of the wheel I permits a further movement of the arm L sutficient to bring it into Contact with the carriage and allow it to come into engagement with the projecting head of the one clutch-pin c, which, being engaged and held in its outer position by means of the pawl a, as shown in Fig. 3, is brought forward thereby against the end of the arm. The recess M is so formed as to be guarded by an overhanging peripheral projection 2', which operates to prevent the arm L from entering the recess at the moment the wheel I begins its forward movement, it being essential that it shall not enter until the movement is completed. The rotation of the shaft K is arrested so soon as its actuatingcrank K has made a complete revolution in either direction by means of a stop N, projecting from the end plate B. A reversal of its movementin either direction when once the movement has commenced is prevented by the engagement of a double-acting detent O, pivoted to the inner face of the end plate B, with a denticulated wheel or ratch P, secured upon the shaft in proximity to said face. The inner end of this pivoted doubleacting detent O is armed, with two teeth h h, (see Fig. 5,) either of which may be brought into engagement with the ratch P by an os cillation of the detent. Each tooth h isheld in engagement with the ratch by means of an angular projection (1 upon the free end of a pivoted swinging latch Q, which is carried by means of a spring j against the angular extremity of an arm 70, extending rearwardly from the pivoted detent. The latch Q, by its automatic engagement with the end of the arm 70, will hold it in position with one or other of the teeth h h in engagement with the ratch P, while the beveled surfacesof the arm and latch will allow the double-acting detent O to be moved to change the engagement of its teeth with the ratchet by causing the latch, to slip back when pressure is applied tov the working end of the detent in the one direction or the other. Pressure is thus applied to the detent O to change its position just before the crank K reaches the stop N in its movement in either direction by means of a pin Z, projecting from the side of the ratchet-wheel P in position to strike an extension m of the detent, formed to overlap the side of the wheel.
The wheel I, carrying the pawl a, is so adjusted with reference to the shaft K, to which it is geared, as that the recess M in the periphery of the wheel will be brought into po-' sition to allow the arm L to drop against the carriage H at the moment the forward movement of the shaft K is completed and its crank K strikes the stop N. Upon the reverse movement of the shaft K the arm L will be thrown back from the carriage H until it strikes a stop-post N, made to project upward from the base A for the purpose. (See Figs. 1 and 2.)
The forward movement of the shaft K (see the arrow in Fig. 2) operates to carry the pawl a forward, and the position of the pawl is so adjusted as that it will carry the projecting clutch-pin c, which it engages, against the end of the arm L simultaneously with the consaid figure is brought to sight and to the line of print the clutch-pin 0 first removed from the normal resting-point of the pawl a. will be forced outward by the push-pin or lug d on the indicating-shaft G, as illustrated in Fig. 2, so that when the pawl (tin its forward movement engages said clutch-pin cit may carry the units-wheel G of the adding mechanism forward one step only, said movement operating in the customary manner to register the one unit.
If the indicatingavhcel be set for the second figure (10 in the drawings) to indicate two units, the second clutch-pin will be forced out to engage the pawl a asit moves forward, so that thepawl in engaging and moving said second pin forward against the arm L will move the adding mechanism far enough to register two units,and so on, the distance of each clutchpin from the normal restingpoint of the pawl a determining the degree of movement of the adding mechanism in correspond ence with the value of the figure brought. to sight and in line for print by the primary adjustment of the shaft (I.
The ratchet XV on theunits-wheel G of the adding mechanism is engaged by a springactuated detent G, pivoted on the shaft K, as shown in Figs. 1 and 2, and which operates in the customary manner to prevent a reverse movement of said units-wheel.
The printing mechanism, by means whereof the payment indicated and registered may be recorded upon a strip of paper, consists of a movable platen R, projecting to overhang the periphery of the type or printing wheel F from a
plate 11*, fitted to slide vertically against the inner face of the end plate B of the machine. This slide-plate or slide R is steadied and guided by means of wide headed studs p p, projecting from the end plate through vertical slots in the slide, (see Figs. 2 and 4%,) said slide being likewise slotted to permit of the passage of the shafts G and K through it. (See dotted lines in Fig. 4.)
The slide R and its platen R are so adj usted as that the platen may drop into contact with the uppermost type on the wheel in manner to produce an impression of the type upon an interposed strip of paper, this movement being enforced by a spring S, attached to slide R and bed-plate A. The platen is then lifted clear of the type to permit a rotation of the type-wheel by means of a cam T, projecting from the shaft K and engaging a pin T on the slide it, as shown in Figs. 1 and 4:.
The cam Tis so adjusted as that when the crank K, actuating the shaft K, is in its normal position at rest, as shown in Fig. 1, the platen shall be in its elevated position, but will drop when the crank begins its forward movement. \Yhcn the platen R is thus clevated, the shaft C is left free to rotate in either direction to permit an adjustment of the indicating-wheel and the type-wheel; but it is locked so soon as the slide R is, by the movement of the crank K, permitted to drop,
and it will remain thus locked until the crank has been returned to its first or normal position and the slide thereby again elevated. This locking of the shaft- 0 is effected by means of a detent U, pivoted to swing freely on the shaft K in position to engage a toothed wheel U, secured upon the shaft 0 adjacent to the printing-wheel, the release of the detent being positiveiy prevented, while the slide R is depressed by means of a lug V on said slide R, which moves into engagement with the end of an arm U projecting from the detent, as illustrated in Fig. 4E.
The automatic engagement of the detent U with the wheel L" is en forced by means of a spring U.
The type brought to line of print under the platen R are inked by means of an inkingroller Y upon the end of an arm Y, mounted upon the shaft K, with freedom to turn loosely thereon, but which is made to move with the shaft by means of a spring-actuated friction-block X, fitted radially in the collar from which the arm projects, so as to bear against the shaft, its pressure thereon being adjusted by a set-screw X. By this means the inking-roller Y is made to swing away from the type at the first movement of the shaft K, and when clear of the type its movement is arrested by a stop 2, while the shaft K continues independently its forward movement to complete its revolution. So soon as the movement of the shaft K is reversed it will carry back the roller Y from the stop if until the roller is arrested by Contact with the platen R, and so soon as the platen is elevated it will carry the roller yet farther over the type and to its first position.
In the operation of the machine theamountof the cash payment to be recorded is first indicated by turning the shaft- C by means of the milled head C. The movement of the shaft C, carrying the imlicating-whecl D, operates simultaneously to turn the printingwheel F, so as to bring the type corresponding to the amount indicated to line of print and to force outward the clutch-pin c in the carriage ll corresponding to said amount, so that its head shall project in position to engage the pawl (t. This being accomplished, the crank K is turned from its normal position of rest at one side of the stop N until it strikes the opposite side, and is then returned to its first. position, thereby causing the shaft K to make a nearly complete revolution in one direction and back again. In the forward movement of the shaft K the pawl athat the units-wheel will turn with it the remainder of the distance, which will be proportional to the Value of the amount indicated,and willthus produce a registry of said amount by the adding mechanism. At the first move of the shaft K the arm L will be carried into contact with the periphery of the wheel I, and just as the shaft completes its forward movement the arm will by reason of the recess M cut in said periphery be permitted to dropin to contact with theperiphe-ry of the carriage in advance of the outwardlyprojecting clutch-pin, so as to provide, in effect, at the completion of its forward revolution a second stop for the shaft K and for the carriage and the units wheel carried thereby. At the first movement of the shaft K upon its return-stroke the arm L is thrown back against the stop-post X clear of the carriage II and of the wheel I. The reverse movement of the shaft operates to carry back the pawl a to its first position. In the mean.- time the shaft 0 and its connections are locked immovably and the printing mechanism actuated by the mediate operation of the slide R in manner as described, while a reverse movement of the shaft K in either direction after the movement has begun and until it is fullycompleted is prevented by the automatic actioirof the double-acting pawl O in manner as described. i
As a modification of myinvention I contemplate constructing my machine with a ber to the figures on the indicator-
is fitted in the
frame 13 of a carriage made to slide longitudinally over the indicatingbar 10. These clutch- pins 14, placed at regular intervals corresponding with the intervals between the figures on the indicatorplate, are left free to play vertically in the frame, and each is formed with an enlarged head to prevent it from dropping inward'upon the slide 10, said head being so formed as not to prevent a suitable pawl from sliding freely over it. Each pin is also automatically held in its inward position by means of an encircling spring 15.' The carriage 13 is mounted in suitable ways to slide longitudinally parallel with the indicating- bar 10, and is attached to a rack 18, which gears with the first wheel 19 in a suitable train of adding-wheels. A lug 16 is formed upon the indicating- bar 10 in such position as that when the pointer 11 is moved to one of the figures on the indicator 12 the lug will be carried under the particular clutch-pin which corresponds in its order or position with the figure indicated and will operate to push said pin up against the stress of its spring and cause its head to project up above the top bar 17 of the carriage.
top bar 17 is fitted a registeringbar 20, adapted to slide freely longitudinally over it. The forward end of this registeringbar 20 is fitted with a spring-actuated pawl 21, adapted to drop and rest upon the top of the bar 17 in advance of the bar 20.
The reciprocating movements of the indicating-
bar 10 and registering- bar 20 may be produced simply by the direct application of lthe hand of the operator thereto or in any other suitable manner known to the art. A reverse movement of the actuating- bar 20 in either direction, when once its movement has commenced, is prevented by the engagement of a double-acting pawl O, pivoted over the bar to engage a ratch 19, formed thereon. This double-acting pawl is armed with two teeth 72. it, either of which may be brought into engagement with the ratch p by an oscillation of the pawl.
This device, which is a modification of the double-toothed pawl 0, applied in manner as hereinbefore described as a double-acting detent to control the movements of the main shaft K, is governed in like manner'by a spring-actuated swinging latch Q, which, by its engagement. with a projecting arm on the pawl, operates to retain it in either position to which it may be carried by the movement of the
bar 20 as it completes its stroke in either direction, the pawl being tripped to change its position at the end of each stroke by means of the projections Z Z on the bar.
In the operation of the machine constructed in this form the amount of the cash payment to be registered is first noted by moving the
bar 10 until the pointer 11 indicates the amount on the indicating plate 12. This movement of the bar 10 will operate to force up the particular clutch- pin 14 which corresponds to said amount. Then by pushing the registering- bar 20 forward its pawl 21 will engage the head of the uplifted clutch-pin and thereby produce a movement of the carriage 13 in unison with the bar 20 for the remainder of its stroke, and the movement of the carriage 13 will actuate the adding mechanism, the extent of said movement being proportionate to that of the carriage and determined by the position of the particular clutch-pin which may be uplifted to engage the pawl 21. If the last pin in the series be thus uplifted, the unit will be registered; if the first, the frame will be moved to its full limit and the highest amount will therebybe registered. 4
The antomaticreturn of the
carriage 13 and registering- bar 20 is produced by means of a spring 22 so soon as the forward stroke of the bar is completed.
