Figure 4 is a diagrammatic view of theelectrical lay-out and instrumentalities essential to the invention.
Referring now in detail to the several figures, the numeral I represents in general the counting machine which has the general rectangular form of a cabinet and is divided from front to back by suitable partitions into a plurality of collecting bins, one of which is shown at 2. These bins are of suitable cross-sectional area to permit the free fall of the bills, and to cause them to stack in a substantially even manner, as indicated by the stack of bills 3 shown in the bottom of the bin. In the actual machine there are a plurality of bins, arranged side by side, but inasmuch as the invention is fully illustrated by reference to a single bin, only one is shown. A solenoid operated counter 4 is associated with each bin, and a master counter 5, also solenoid operated, counts in common, for all of the bins. bin is a pair of rolls, the lowerroll 6 of each pair being driven by means such as the common shaft 'I, which extends along the front of the machine. The upper roll 8 of each pair normally rests upon the central part of the lower roll 6 and is mounted in a stirrup 9, which has a limited up and down movement and is provided with a stud I0 which moves against the plunger II of a micro-switch I2. Figure 2 indicates in broken lines and somewhat diagrammatically, the intern-al construction of the micro-switch showing that the plunger II presses against one of two normally open contacts, bringing them together. The contacts, when open, are only a very small fraction of an inch apart. A bill is presented endwise to the l" rolls, the narrow central portion of the roll 6 causing the bill to assume a concave form so that it will pass between the rolls as a rigid body. The rolls will be separated from one another during the passage of the bill by an amount equal Qi to the thickness of the bill, which will cause the stud IU to push the plunger I I against the switch, closing the contacts.
Figure 4 shows that the micro-switch I2 is in a series circuit with the solenoids I3 and I4 of both the individual and master counters and with the line current so that when the micro-switch I2 yis closed the solenoids I3 and I4 are simultaneously energized and the respective counter armatures I5 and I6 are moved to a position bridging the poles of the solenoids, thus moving the counter arm I'I to a potential position with respect to the counter operating mechanism so that when said counter arms are released the counters will be operated. It is obvious that when a bill is In front of each the closed switch I2 and through both the solenoids I3 and I4 and to ground so long as the switch I2 remains closed, that is to say, during the entire period of passage of a bill between the rolls. All this time the arms I'I of the counters would be held in potential position and not until the bill had completely passed between the rolls and the latter had come into contact with one another would the de-energization of the solenoids of the counters take Place through opening of the micro-switch I2. After the opening of said switch, there is an appreciable time interval before the solenoids I3 and I4 can become de-energized yand. before the armatures I5 and I6 can move the actuating arms I'I of the counters sufficiently to have operated the counters. If another bill is presented to the rolls E and 8 so `quickly after the preceding bill as to separate the rolls and close the switch I2 before the solenoids I3 and I4 have had time to completely de-ener- -gize and before the mechanical lag in the counter mechanism has. been overcome, the microswitch will again be closed and the solenoids I3 `re-energizedV before the counter mechanism has 4hadthe opportunity to register the count of the -preceding bill.
This makes it necessary thatythe onev who is feeding bills into the machine shall wait a suiilcient time after the complete passage of the preceding bill to assure thatthe parts have -returned to their normal repose position readyto repeat their countingfunction. With the drive shaft 1 feeding the bills through at the normal Yrate of speed, it is found that the one who feeds jbills to the machine must not present the bills vcloser than within about live-eighths of an inch of one another. This decidedly slows down the 'operation of the machine.
By the present invention, the circuit made by the closing of the micro-switch I2 is immediately broken while the billis still running through between the rolls 6 and 8, so that the period ofv lag lboth electrical and mechanical in the counter mechanism, and the countregistering movement of the arm I'I are both completed While the bill is still running between the rollsfso that when the bill nally completes its passage between the rolls, .the solenoids I3 and I4 willbe in readiness to be again rfa-energized, andthe arms II will be in a position of repose in readiness to b e drawn to its potential position through energization of the l solenoids.
The Ameans which" I havefprovided for accomplishing thisy function comprises a vpair of Vauxiliary contacts I8 and AISI mounted on the master counter, thercontact I8 being stationary and the contact I9 beingrmovable. These contacts, when closed, establish'a circuitl through a relay 2D. Said relay has a Contact Zl which nor- Awithdraws the contact 2| from the micro-switch circuit, opening that circuit, yde-energizing the solenoids VI3 and I4, causing `the arms I I to actuate `the countingi mechanism to" register a .count on both the individual. and' the master Y'2,21'7'1J-.9"l: counter, thecount registering movement'of the yarm I1 of the master counter breaking the' cony tacts lvand I9. M It is observedrthat when the micro-switch I2 vinitially closes, an alternative circuit is provided which is established from the line through thel not enough to actively energize thesolenoid I3 which actuates the counter.
It will not do, however, for the 'relay v28 to become de-energized immediately after its energization by the Aopening of the contacts '|8`and 19,'for the armature of the relay would drop,
causing the contact 2l to close the gap inthe micro-switch circuit, andthe latter being still closedA through the passage of the bill, the solenoids I3 and I4 would become again energized, operating lthe counting mechanism and thus registering two or more counts for a single bill.
.To prevent this -eventuality, I have provided a holding circuit through the relay 20, which is established whenthe contacts I8 and I9 close and the larmature ofthe relay 28 lifts,-but which is not broken when the contacts I8 and I9 separate. 'It will be observed from the rdiagram in Figure 4 that the circuit established through the relay 26 by the closing of the contacts I8 and I9 includes only a single resistance 22 so that the current may be regarded as a powerful current capable of actuating the relay to draw its armature upwardly, considering the position of parts in the'diagrammatic figure. f
When the armature of the relay 28 is in its uppermost position, the contacts and 26 are closed, which cuts out the resistance 2,4 so that current continues to pass through Vtheg'relay by way of Ithe alternative paththrough the solenoid I.3"and through tworesistances 22 and 23. This current is not enough to cause the relay 28 to attract its armature, but it is enough to cause the relay to hold on to its armature. Consequently, when the contacts I8 and I9 are broken through the de-energization of the solenoids I3 and I4, the relay 20 is not cle-energized;
therefore, it is impossible for more than one count to be made by the counter during the passage of a single bill.
Thus, during the passage of a bill between the rolls 6 and 8, the solenoids of the counters are first energized, placing the counter arms II in a potential position. Energization of said solenoids causes an immediate energization of the relay 20, which in turn causes immediatedeenergization of the counter solenoids, causing a count to be registered upon the individual and master counters, but the relay 28 remains energized during the entire passage of the bill, as a safeguard against the duplication of the count. Then when the billhas completely passed through between the rolls E and 8 and said rolls have come together, opening the micro-switch, the cirhow fast to 'feed the bills to the rolls. They may be fed as close to onel another as possible, without fear of' a miscount or a duplicate count, it being understood, of course, that the bills must be fed so as to allow some space between successively fed bills.
The adjusting screw 21 in Figure 1 determines the clearance betwen the rolls 6 and 8, necessary to close the contacts of the micro-switch. If this clearance is set to the thickness of the one bill and two bills are fed in, overlapped, the micro-switch will, of course, close, but the upward thrust against the adjusting screw which `is carried by the rocker arm 28 tilts the rocker varm about the pivot 29, operating brake mechanism 30, which will stop the motor,- not shown, bymeans of which the feed rolls 6 are driven.
While Ihave in the above description disclosed 'what I believe to be a preferred and practical embodiment of the invention, it will be under-V stood to those skilled in the art that the specific details as shown and described are by way of example, and not to be construed as limiting the scope of the-invention as defined in the appended claims.
