Application filed June 14,1901. Serial No. 64.558.
f ft/j/ 10/1/0177, it Huey concern:
Be it known that I, THOMAS CARNEY, a citizen of the UnitedStates, residingat Dayton, in the county of h'lentgomery and State of Ohio,have invented certain new and useful 1m provements in Time-Printing Devices, of which I declare the following tobe a full, clear, and exact description.
My invention relates to improvements in time-printing devices, as shown, for example, in the patent to Kruse and IVeiss, No. 147,0231, granted February 24:. 1891.
In the drawings, Figure 1 shows a vertical section through acash-register having my invention applied thereto. Fig. 2 is afront elevation of the clock detached. Fig. 3 is a top plan view of a printing cash-register with my invention applied thereto. Fig. 4: is a vertical section through the machine on the line 4: a of Fig. 3. Fig. 5 is a detail view of the motor-spring and the motor-gears of the machine. Fig. 6 represents an end view of the cash-register, showing the printer in elevation and the clock and its connections in section. Fig. 7 is a detail perspective view showing the pawl for actuating the time-printing wheel. Fig. 8 shows an elevation view of the slide which operates to throw the check-printer hammer into operative connection. Fig. 9 shows a perspective view of the lower printerhammer with the hub which is secured thereto. Fig. 10 shows a short portion of the detail-strip as printed by the machine.
My present invention has no relation to the particular form of cash-register to which it is applied, and it is only for purposes of illustration that I have shown it as attached to a cash-register substantially like that of my pending application, Serial No. 20,385, filed June 15, 1900.
Referring to the drawings, 10 designates the fixed frame in which the various parts are supported and ournaled. The registering-keys 11 are of the lever type and are hung about central upon a transverse shaft 12. Extending verticallyabove the rear end of each key is its cof'iperating indicator or tablet rod 13. Each key has a registering-plate 1a, which is secured to said key near the rear end thereof and extends vertically upward. As shown, in machines of this class those of the keys which are arranged to register values are grouped in banks, nine keys to each bank. Except for the immber-buttons on the front ends of the keys each bank of said keys is a duplicate of every other bank; but each key in any one bank is different from every other key in that bank that is, the degree of inclination of the registering slot 15 of any key is different from that of all the other keys in the same bank. This is clearly shown in Figs, 1 and 4:, from which it will be seen that the entrances of all the registering slots are arranged in horizontal alinement and directly under the cross-rods 16 of the registering-frames 17, which carry the registering-segments 18. If any registering slot were formed upon an arc struck from the center of the supporting-shaft 12, it would not when its key was operated move the registering-segment at all; but each registering slot during the first portion of its length varies from said are. The distance that the registering slot of the 1 key varies from said are may be regarded as a unit, since the registering slot of the 5 key varies five times as much and that of the 9 key nine times as much, etc.
Each key when operated has to be moved just as far as any other key; but by the means just described the different keys are made to transmit differential movement to the counterwheels through the registering-frames 17. Each registering frame and segment 18 is normally locked by the locking-frame 19, which is pivoted upon the cross-shaft 20 and has a cross-rod 21. The lower end of the frame stands normally just behind the cross-rod 16 of the registering-frame. The registeringsegment therefore is thus locked against any improper movement; but when a key is operated the upper rear corner of its registeringplate immediately strikes the cross-rod 21 of the locking-frame and forces the lockingframe 19 backward out of the path of movement of the registering-frame.
The counter 20, as usual, is composed of a number'of wheels having numbered peripheries, and they are all journaled on the counter-shaft 21, which is journaled in the counter-frame 22, which in turn is journaled upon the cross-shaft 23. Near the lower corner of its front end the counter-frame is provided with a stud 24, (shown in broken lines in Fig. 1,) which travels in the groove 25 of the boxcam 26. The box-cam is secured upon the rotation-shaft 27, which is arranged so as to make a single complete rotation at each operation of the machine. The shape of the camgroove is such that the initial movement of the key rocks the counter-frame 22, thereby throwing all of the counter-pinions 28 into engagement with the registering-segments.
Each registering-key has formed in the front edge of its registering-plate the usual coupling-slot 29, which cooperates with the universal bar or key-coupler 30 in the usual manner.
The rotation-shaft 27 is given its single complete rotation at each operation of the machine by the rotation rack-bar 31, (shown in Fig. 1,) the lower end of which is bifurcated and straddles a headed guide-pin 32. Nearits upper end the rotation rack-bar is provided with two series of rack-teeth, one in the front edge and one in the rear edge, and it is arranged to vibrate between the pinion 33, which is secured upon the rotation-shaft, and the pinion 34, which is journaled upon the stub-shaft 35. An intermediate pinion 36 is placed between the rotation rack-bar and the adjacent end frame of the machine and at all times is in mesh with boththe pinions 33 and 34. At the upper end and secured to the inner side of the rotation rack-bar is a stud 37, which cooper ates with a ridge 38, formed upon or secured to the inner side of the end frame of the machine; The ends of the stud 37 and of the ridge 38 are beveled, as shown.
A shifting-spring 39 is secured at one end to the frame of the machine and at the other to one of the legs forming the bifurcated lower end of the rack-bar. It is attached to the rack-bar at a point about midway of the length of said leg. In the normal position of the parts, as shown, the spring is above the guide-pin 32, and therefore draws the rotation-rack into engagement with the pinion 34. When a key is operated through the operating-arm 39 which is rigidly secured to the key-coupler 30, the rack-bar is moved downward. It results from this that as the point of attachment of the shifting-spring 39' that is, when it returns to normal position the rack-bar is shifted back into engagement with the pinion 34, as will be readily understood. There is a slot-and-pin connection between the arm 39 and the rotation-rack, which permits the latter to be shifted while being moved by said arm.
As usual in machines of this class, the typewheels 40-for printing the amounts of the recorded transactions are geared directly to the registering segments. In the machine as shown the registering-segment, which is arranged to register dollarsthat is, the one shown in Fig. 1 and the left-hand one of those shown in Fig. 3is connected with its typewheel through the printer-shaft 41. The pinion 42 upon the left-hand end of the shaft is always in mesh with its respective segment and transmits the movement of the latter to- The segment for registering tens of cents is the middle one of those shown in Fig. 3 and its type-wheel is the middle one of the three type-wheels 40, which are shown in that figure. It is connected with its type- 'wheel by a sleeve 43 on the printer-shaft.
(Shown in broken lines in Fig. 1.) In like manner the segment for registering cents is the right-hand oneof those shown in Fig. 3 and is connected with its respective type-carrier through the sleeve 44, which encircles and turns upon the sleeve 43. In these respects the cash-register as shown in the drawings is substantially identical with the construction shown in the patent to me granted May 23, 1893, No. 497,861, and, as in that patent, all of the printingwheels have the types arranged upon their peripheries in duplicate series, so that the detail-strip may be printed by receiving an impression from the lower printer hammer or platen 45, and exactly the same characters may be printed upon an inserted check by the upper printerhammer 46. The printer-hammers are mounted upon arms 47, which have pivots 48, securing them to the printer-frame 49.
The various parts of the printer are operated from the key-coupler, which, it should have been explained, is secured to the keycoupler shaft 50, whose ends are journaled in the frame of the machine and the right-hand end of which projects through the printerframe 49 and has secured upon it the segmentplate 51. The latter is provided with a segment, which is always in mesh with a corresponding segment on the actuating-pawl carrier 52, which is pivoted upon the shaft 53, which supports the supply-roll 54. There is pivoted to the pawl-carrier near its rear end the actuating-pawl 55. This is in position normally to engage the hook 56, which is carried by the lower printer-arm 47, whereby whenever a key is operated the key-coupler is actuated and the pawl-carrier 52 is rocked,
the lower printer-hammer until the disengaging-arm 57 of the actuating-pawl strikes the stop-pin 58, thereby disengaging the lower printing-hammer and permitting it to make its printing stroke under the impulse of its spring 59.
W'hen it is desired to print a check, the check-key 60 must first be pressed, then the check is manually inserted under the upper or check-printing hammer, and then when the 1 machine is subsequently operated the cheekprinting hammer is moved simultaneously with the lower printing-hammer and identical impressions are made upon the check and upon the detail-strip. This simultaneous operation of both hammers or platens is brought about through the operation of the check-key, which raises a vertical slide 61, which is provided, Fig. 8, with two elongated slots 62, through which pass the stud 63 and the lower one of the pivot-shafts 48, respectively. The slide lies close against the printer-frame t9 and between said frame and the printer-hammers. Near its upper end it has a notch 63, into which extends a pin 64, which is carried by a clutch member 65' The latter has a bifurcated lower end, and the two legs thus formed straddle the lower pivot-shaft &8. A detentpawl 61 is pivoted upon the outer end of the stud 63. It has a horizontal arm 61 and a vertical arm, which is provided with a notch 61". Cooperating therewith on the Slide 61 is a projection 61. hen the slide is raised by the operation of the check-key, the projection thereon passes to the level of the notch 61, whereupon the detent-pawl is thrown under said projection, so as to lock the slide in its upper position to compel a subsequent operation of the upper printinghammer. The horizontal arm 61' is the releasing means, and when the actuating-pawl is returned to normal position after having released the hammers its disengaging arm 57 strikes the horizontal arm 61", thereby rocking the detentpawl from under the projection 61, whereupon the slide 61 and the check-key 6O immediately resume normal position under the impulse of the spring 60, which is coiled upon the pivot-shaft of said check-key.
In order to have a wider bearing for the lower printer-hammer arm, the hub 66 is secured rigidly to it and is journaled upon the lower pivotshaft. It is also necessary to have wide firm bearings for the clutch member whereby it may move freely in a vertical direction, but be prevented from swinging laterally independent of the printer-hammer. To this end, as shown in Figs. 6 and 9, slots are cut in the hub on opposite sides, and through these slots slide the legs of the bifurcated ends of the clutch member. As the hub is rigidly secured to the printor-hammer, it will readily be seen that the clutch member can readily be moved vertically, but has no latto actuating the time-printing wheels.
p'rinter-hammer. hen the check-key is pressed, the lower wall of the notch 63 strikes the inner end of the pin, and thereby raises the clutch member so that the pin enters the vertical slot 67, formed in the upper printerhammer. Thereafter when the amount-keys are operated the lower printer-hammer is swung downward, as already described, thereby swinging the clutch-member pin 6 forward, and as it is in the slot 67 the upper hammer is thereby raised. Of course when the actuating-pawl 55 is disengaged both the hammers are simultaneously operated by their springs 59. Normally the clutch-member pin is entirely out of the notch 67, and therefore the check printer-hammer is not actuated except when the check-key has been previously set by depressing it.
The detail-strip 68 and the continuous inkribbon 69 are given a definite movement in a forward direction at each operation of the machine by means of the feed-pawl 70, which is pivoted at its lower end to the segmentplate 51. At its upper end it engages a ratchet-wheel 71, which is fast to and carried by the intermediate gear 7:2, which meshes with the lower gear 73, which carries the storage-roll 74, and the upper gear 75, which carries the drum around which the ink-ribbon passes. A retaining-pawl 7 6 also engages the ratchet-wheel 71 to prevent retrograde motion of either the detail-strip or the ink-ribbon.
The time-printing device may be located wherever convenient; but in the present instance I prefer to place it above the wicket or window through which the indicators show, because when thus located it admirably serves the purpose of an ordinary clock in addition The clock itself may be of any preferred variety. In the drawings 1 have shown a clock having a motor-spring 77, which, as usual, is secured at one end to the winding-shaft'TS and at the other to the main or motor gear 79. A ratchet-wheel is rigidly secured upon the winding-shaft, and a retaining-pawl 81, which is pivoted to the fixed frame, engages the ratchet-wheel to prevent retrograde movement when the windingshaft is turned to put the motor-spring under tension. The usual pinion 82 and intermediate gears 83 and 8a transmit the movement from the motor-spring to the minute driving-shaft 85. The latter has the usual escapement mechanism, including the balance-wheel 86, the pallet 87, &c., to regulate and control the movement of the minute driving-shaft. The hourhand is carried upon a sleeve 85, which surrounds the forward and reduced end of the minute driving-shaft 85, as shown in Fig. 2, and this sleeve 85 is fast to a pinion geared to the minute driving-shaft 85, so as to receive one-twelfth of the movement of said shaft 85, and thereby be driven as the hourhand is ordinarily driven. The minute-hand eral movement independent of the lower l is attached to a sleeve 108, loosely surroundregister frame at 90.
ing the sleeve as also shown in Fig. 2,
and this minute-hand has an independent driv' ing means, as will later be described, not being connected in the ordinary manner to the clock mechanism. Upon the rear end of the minute-shaft 85 is a cam-wheel 88, having twelve teeth formed thereon, and this shaft 85 revolves once in each hour in the ordinary manner, thus revolving the can] 88 once in each hour. As above stated, the minute-hand is not operated directly from this shaft 85, but is operated by other means, as will be later described, and the means of setting the minute-type carrier from the shaft 85 is as follows: Cooperating with the cam-wheel is a bell-crank lever 89, which is pivoted in the rear of the clock to the upper part of the cash- Its upper end is beveled, as shown, so as to engage the teeth of the cam-wheel. Its lower or right-hand end has a jointed connection with a vertical slidebar 91, which is held in position against the vertical side frame of thecash-register by two headed pins 92. At its lower end the slidebar has a slot-and-pin connection with a second bell-crank lever 93, which is pivoted at 94 to the printer-frame, Fig. 6. The lower end of the bell-crank lever 93 has a slot-and. pin connection with one arm of a pawl-carrying yoke 94, Fig. 7. The other end of said yoke carries the well-known form of pivotactuating pawl 95, having three fingers 96, which are arranged at graduated inclinations and respectively engage the hourprinting wheel 97, the minute-printing wheel 98', and the meridian-printing wheel 99. In the present instance the middle one of the actuatingpawl fingers is longest or has the greatest inclination, whereby at every reciprocation of the actuating-pawl the minutes-printing wheel is turned one step, as will be readily understood.
There is a double series of twelve printingtypes upon each of the time-printing wheels, and duplicate printing-types of each series are arranged at diametrically opposite points, so that when the hammers are operated the same impression is simultaneously printed upon the tape by the lower printer-hammer and upon the inserted check by the upper hammer. The printing-types of each of the duplicate series upon the minutes-printing wheel are of denominations as follows: 5, 10, 15,20, 25, 30, 35, 40, 15, 50, 55, 60. Upon the hour-printing wheel there are duplicate series of printing-types arranged to print the hours from 1 to 12. The types on the meridianprinting wheel are arranged to print A. M. and P. M., and these abbreviations alternate around the periphery of the said printing-wheel.
Secured to the side of and carried by each printing-wheel is a ratchet-wheel 97 having two deep notches 98 at diametrically opposite points. In like manner the ratchet-Wheel of the meridian-printing wheel is provided with two deep notches at opposite points. As has been said, the finger of the actuating-pawl which turns the minutes-printing wheel has the greatest inclination of the three, and therefore the minutes-printing wheel is moved one notch at each reciprocation of the actuatingpawl. The finger which actuates the hourprinting wheel has the next greatest inclination, and when, therefore, the middle finger in turning the minutes-printing wheel falls into the deep notch of its ratchet-wheel 97 'the right-hand finger 96 drops far enough to engage the ratchet-wheel which is carried by the hour-printing wheel, and the latter is thereupon moved one notch. As the finger which actuates the meridian-printing wheel has the least inclination, that wheel will only be moved one notch when the hour-printing wheel has been moved twelve-notches. The minute-wheel therefore is moved every five minutes, the hour-wheel every hour, and the meridian-wheel every twelve hours.
The actuating-pawl is reciprocated by the conjoint action of the cam-wheel and its spring In turning, one of the cam-teeth strikes the bell-crank arm 89 and gradually slides past the beveled upper end thereof, which is held against the cam-wheel by the tension of the spring 99. The movement of the camwheel forces the bell-crank lever downward, retracting the actuating-pawl until the tooth which is in contact with the bell-crank lever passes by the latter, whereupon the spring 99, being temporarily unrestrained, swings the bell-crank 93 downward and the actuatingpawl forward until said bell-crank strikes a suitable stop, such as the pin 100. This operation, as will be readily understood, swings the actuating-pawl forward and causes the latter to turn the minutes-printing wheel one notch. The upper bell-crank 89 is also thereby swung upward, so that its beveled end is thereby brought into the path of movement of the succeeding tooth of the cam-wheel. In this manner the clock operates to intermittently turn the time-printing wheel.
In order to move the minute-hand synchronously with the minuteprinting wheel, I pivot to the upper bell-crank lever 89 a link 102, Fig. 2. At its upper end the link is pivoted to a short crank-arm 103, which is fast upon the rear end of a short shaft 104. Upon the other or front end of said shaft is secured the pawl-carrying arm 105, to the upper end of which is pivoted the minute-handactuating pawl 106, which engages the minute-hand ratchet-wheel 107, which is fast upon the rear end of the aforesaid short sleeve 108. Upon the front end of this sleeve the minutehand is secured, and of course the minutehand can thus move independently of the minute driving-shaft 85. Under this construction it results that whenever the camwheel 88 actuates the bell-crank 89 downward Lil the link 102 is thereby reciprocated, which rocks the short shaft 104:, which causes the actuating-pawl 106 to be reciprocated, so as to advance the ratchet-wheel 107 the space of one tooth. As the minute-hand is integral with the ratchet wheel 107, the former is thereby moved twelvetin'ies during each hour. It advances by jumps from one indicatingnumber on the clock to the next.
In order to prevent retrograde movement of the ratchet-wheel 107, and consequently of the minute-hand, the retaining-pawl 109 is pivoted upon the shaft 104, and its upper end engages said ratchet-wheel. Its other end is connected by a light spiral spring 110 with the actuatingpawl 106, whereby both of said pawls are held to engagement with the ratchetwheel 107.
A principal feature of my invention comprises means for automatically winding up the clock by the operation of the cash-drawer, as best shown in Figs. 2 and a. To this end I provide a \vimlingpawl 111, which is held to engagement with the winding-ratchet by a spring-arm 112, which is pivoted to the wind ing-pawl and has a spring 113 intervening between it and the said pawl. The upper end of the spring-arm bears against the vertical standard lls of the clock-frame, and thereby, as described, holds the actuating-pawl engaged with the winding-ratchet 80. Movement from the cash-drawer is transmitted to the actuating-pawl, and hence to the winding-ratchet, through the horizontal lever 115, the vertical slide 116, which is jointed to the left-hand end of said lever, the vertical link 117, and the bent lever 118, which is pivoted to the side frame of the cash-register at 119. hen the cash-drawer is closed,an antifriction-roller 120, which is carried by the bracket 121 upon the rear side of the cash-drawer, strikes the bent lever 118, thereby swinging its upper end downward and forward and reciprocating the winding-pawl so as to turn the winding ratchet-wheel 80 one tooth.
\Vhen the cash-register is first put into use or if the clock has run down through nonusage of the register, the motor-spring may be wound up or put under tension by either opening and closing the cash-drawer a number of times or by means of a regular clock-key which may be applied to the square front end of the winding-shaft 78. The motor-spring is preferably strong enough to run the clock several days, so that except when the machine is first started or when the cash-register has been out of use for some time no attention whatever need be paid to winding up the clock.
As the drawer might be closed so often as to wind the motor-spring too tight, provision has been made for rendering the winding devices inoperative when a certain tension of the spring has been reached. To this end the horizontal lever 115 is pivotally secured, not to a rigid part of the frame, but, on the contrary, to a heavy spring-bar150, formed, preferably, of steel. It may be said to be in the form of a bridge in that it has two feet 151, one at each end, and these feet rest upon the cross-plate 152 of the frame of the machine. The lever 115 is pivoted about midway be tween the ends of the spring-bar. It results from this construction that when the drawer is operated the motor-spring will be wound until the spring is so tight that the resistance it offers to being further wound exceeds the resistance that the spring-bar olfers against being bent. In other words, it takes a certain force to bend the spring-bar downward at the point at which the lever 115 is pivoted to it, and so long as the power thus required is greater than the power required to further wind the spring the actuating-pawl 111 will move the windingratchet one teeth at each operation of the drawer. hen, however, the power required to turn the winding ratchet-wheel exceeds that required to bend the spring-bar, the actuating-pawl no longer turns the winding ratchet-wheel far enough for the detentpawl to engage another tooth, because the spring-bar simply bends, and therefore the actuating-pawl is not moved far enough to turn the winding-ratchet the distance between its successive teeth. In this manner I prevent the motor-spring from being wound too tight.
It will be readily understood that instead of having the clock wound by the cash-drawer I might arrange to have the Winding done through a connection between the winding ratchet-wheel and any part of the cash-register which has a definite movement at each operation. For example, it would be a very simple matter to have the winding connection operated from the universal bar or key coupler 30 instead of from the cash-drawer.
Having thus described myinvention, Iclaim as new and desire to secure by Letters Patent 1. In a cash-register, the combination with a printing mechanism, of a clock-movement, time-printing types, setting means intermediate the clock-movement and said types, winding devices for the clock, and a yielding support for the winding devices whereby the clock is no longer wound when the tension of the yielding support becomes less than the tension of the clockspring.
