Application January 31, 1949, Serial No. 73,745

4 Claims. (01. 235-132) This invention relates to machines for use in sorting and counting paper currency, and is an improvement over the machine disclosed in U. S. Patent No. 2,el29,l59, granted to Thomas E. Hayes, October 14, 1947. More particularly, the invention relates to improved means for automatically stopping the machines when desired numbers of paper bills have been inserted therein.

The paper bill counting machine disclosed in Patent No. 2,429,159 is designed to be adjusted so that the machine will automatically stop when one hundred bills have been inserted or when fifty bills have been inserted, whichever is desired. This is accomplished by placing a pair of cams upon the tens wheel and positioning a switch so as to be operated thereby. Through selective electrical circuits, the desired run of the machine may be obtained.

It has been desirable to further break down the stacks of bills, particularly with bills of larger denomination, and therefore desirable to automatically stop the machine when twenty-five bills have been inserted. Heretofore this has not been possible, as the counters used count to 99 and then return to 00. These counters employ a units wheel and a tens wheel, the tens wheel being moved one step each complete revolution of the units wheel. To stop upon a count of 25 would cause the machine to stop when the counter register 25, 50, 75, and 00. With the conventional counter, some means would have to be worked out to operate a switch from both the units wheel and tens wheel, but only at times when the two are in certain relationships to one another. At all other relative positions of the wheels, the circuits controlled by the switch would have to be open.

The object of the present invention is to provide a bill-counting machine having means to automatically stop the machine upon the insertion of twenty-five, fifty, or one hundred bills at the will of the operator, whereby when the machine is set it will stop every time the selected number of bills has been inserted.

Another object of the invention is to provide improved means for controlling the stopping of the machine.

A further object is to provide an improved counter mechanism for actuating the circuits controlling the operation oi the machine.

Other objects of the invention will become apparent from the following description of one embodiment thereof, when taken in conjunction with the drawings which accompany and form part of this specification.

Referring to the drawings in detail, the billcounting machine in its general aspects is the same as that disclosed in Patent No. 2,429,159, and comprises a cabinet I having a back 2, the cabinet being divided into a plurality of cornpartments 3 by vertical partitions 4. Each coinpartment is divided into a lower section and an upper section by means of hinged shelves 5 which normally lie in a horizontal plane to form r a platform to receive bills fed into the machine,

but may be released to permit the accumulated bills above to drop into the section below. The construction and operation of these shelves is well known in the art and plays no part in the present invention. Each of the compartments is designed to receive bills issued by a particular Federal Reserve Bank, there being a sufiicient number of compartments to provide one for each such bank.

The operator feeds successive bills to the par ticular compartments designated to receive them in accordance with the bank of issue. The bills are fed between pairs of feed rollers located at the upper front of each compartment at a position above the shelves 5. The feed rollers comprise a lower driven roller 6, one for each compartment, and an upper roller 7 driven from the lower roller 6 when a bill is inserted between the rollers. The rollers 8 of all of the compartments are mounted upon a single shaft 8 which extends completely across the machine and is mounted in bearings on the front of the machine and driven by a motor 9, not shown in the structural views but only in the wiring diagram. Except at such times as will be described later, the motor 9, and consequently the rollers 6, operate continuously. Each upper roller 1 is mounted in the bifurcated end of a bell crank lever iii, pivoted at H, for rocking movement. The opposite end of lever ill is provided with an adjustable stop I2 fo r abutting the control button of a micro-switch [3. By adjustment of the stop t2, the roller i can be held out of contact with the roller 6, and roller 7 will rotate only when a bill is inserted between the rollers. Insertion of a bill will lift the roller 1, tilt the lever Ii) about its pivot H, and move the stop 12 from the micro-switch control to permit the switch to close. This structure is disclosed in detail in pending application, Serial Number 677,859, filed June 19, 1945, now Patent No. 2,494,615. v

For each compartment, there is a piececounter [A mounted at the back upon the top of the machine where it is clearly visible to the operator. Each piece-counter is operated by a pair of coils l having pole-pieces [6, between which an armature ii is positioned. Upon energization of the coils by closure of micro-switch I3, due to a bill being inserted between the rollers of a feed-roller pair, armature i1 is caused to move and its movement is imparted to the operating lever E3 of the piece-counter through the medium of linkage is. This structure and operation, as well as the operative connections between the piece-counters and the totalizer are described in detail inv Patent No. 2,429,159, and will be referred to in more detail herein in connection with the wiring diagram of Figure 12.

The tot'alizer 26 is mounted upon the top of the machine in the same manner as the piececounters, but at one end of the machine. The totalizer is one 'of the novel features of the present invention and will be described in detail.

The totalizer in general comprises two counter units mounted upon a single shaft, one of the units being, and operating, as is conventional, and the other operating at twice the speed of the first, so that when a count of has been reached upon the conventional unit, the special unit will have counted 50. By operating switches by the tens wheel of the special unit at and 00 count on that unit, an accurate control may be had for counts of 25, 50, 75 and 100 on the standard unit.

The totalizer in detail comprises a housing 2i having the usual sight window 22. Journaled in one end of the housing, there is a short shaft 23 which carries a yoke 2 The inner end of shaft 23 is bored axially to form a recess 'to receive the reduced end 25 of a shaft 26 upon which the yoke 25 turns, which has its opposite end journ'aled in the other end wall of the housing and extends beyond the housing to receive a knurled knob 35. All of the moving parts of the counter are "mounted upon the shaft 26.

Upon the shaft 26, there are two complete counter units, a conventional unit 21 and a dummy, specially constructed, unit 28. The actuating mechanisms of the two units are tied together for simultaneous action, but due to the difference in construction of the units different results are obtained.

The standard, conventional unit 27 comprises a units wheel 25 and a tens wheel Bil in side by side relationship upon shaft 25. Each wheel carries a toothed drive wheel, units wheel 29 having the driving wheel 3!, and tens wheel 30 the driving wheel 32. Tens wheel 39 also has a hub portion '33 on the opposite side from the driving wheel. The units wheel and tens wheel are each hollow being composed of a base and a cap in the form of a cup. Within the wheels there are spring pressed dogs 3% cooperating with a stop 35 mounted and keyed upon the shaft 26. The stop and dog assembly function to permit free turning of the wheels in one direction, but provide means for picking up the various wheels by rotating the shaft 26 by means of knob 36 to return the wheels to zero position as is well-known in the art.

The unit 2? is operated by oscillating the short shaft 23. The outer end of shaft 23 is squared and receives an operating lever similar to the operating lever i8 of the piece-counters. Upon energization of the totalizer coils 15, the armature will be caused to move imparting a movement through the operating lever to shaft 23. When the current is broken the shaft will be rocked in a reverse direction bringing the shaft back to its original position. As mentioned above, shaft 23 carries yoke 24 and movement of the shaft will result in a similar rocking movement of the yoke. A shaft 38 extends between the arms of the yoke and carries two dogs 39 and iii, the dog 39 being in thesame vertical transverse plane as driving wheel 3| and dog to in a similar plane with respect to driving wheel 32. The shaft 38 is biased by spring ii to urge the dogs toward driving wheel engagement. It will be noted from Figure 10 that the dogs 39 and it are not positioned in the same radial plane with respect to the axis of shaft 38 but that dog 39 is in a more advanced position, or closer to the periphery of its driving wheel. Due to this arrangement, dog 39 may ride upon the periphery of driving wheel 3i, contact the projections 42 thereon to rotate the wheel when the yoke is oscillated, while dog it! will be held out of engagement with the driving wheel 32. Thus the units wheel may be advanced step by step without disturbing the setting of the tens wheel.

Latches

33 and 44 contact the teeth on the respective driving wheels 3! and 32 to hold the

wheels

29 and 33 against accidental movement.

As is usual in counters, driving wheel 3! is provided with a notch 35 which is designed to receive the dog 39 when the wheel 29 registers 9, so that dog 39 may move in closer to the center of driving wheel 31 to permit dog 40 to contact teeth 46 on the periphery of tens unit driving wheel 32. Upon the next forward movement of yoke 26 both

wheels

29 and 30 will be moved, the wheel 29 to 0 position and the wheel 30 to register 1. When the yoke moves back dog 39 will ride out of the notch 4-5 lifting dog 40 from engagement with its driving wheel. In this way the units wheel may make another complete revolution before the tens wheel will again move. t

The above is standard counter construction and has only been described in suiiicient detail to give an understanding of the present invention.

The dummy unit 28 is essentially the same as the standard unit 2'1, with one important structural, and consequently operational detail. The unit 28 comprises a units wheel 41 and a tens wheel it, similarly arranged on shaft 26 to

wheels

29 and 33, which have spring pressed dog 49 and stops 53 to permit free movement in one direction and provide means for reseting. Driving wheels and 52 are carried by the

wheels

61 and 43, respectively, and each has teeth as shown at 53 on 5|, and 54 on 52. A yoke 55, identical to yoke 24, is pivoted on shaft 26 and secured to yoke 24, as by turned tongue '56, Figure 4, to move with yoke 24. A shaft 51 extends between the legs of yoke 55 and carries a dog 58 for engagement with driving wheel 5| and dog 59 for engagement with driving wheel 52. Spring 50 biases the shaft to urge the dogs toward their respective driving wheels. Latches 3| engage the driving wheels to limit their movement to one direction and prevent back movement under the frictional drag of the returning dogs '58 and 59, or other moving parts.

The structural difference between the dummy unit and the regular unit lies in the driving wheel 5|. It has been pointed out that the driving wheel 3! for the units wheel 29 of the regular unit is provided with a notch 45 to receive the advancing dog 33 so as to permit movement to be imparted to the tens wheel one step each revolution of the units wheel. Driving wheel 5! of the dummy unit has two such notches, 82 and 53, diametrically opposed. Although neither the units wheel nor the tens wheel of the dummy unit are provided with numerals, the driving wheel 5| is so positioned with respect to the advancing dog 53 that the dog will drop into a notch to produce movement of the tens wheel when the units wheel 29 of the conventional unit is to move from 4 to 5 and again when the wheel 29 is to move from 9 to 0.

Thus it will be seen that the tens wheel 43 of the dummy unit will be moved two steps for each complete revolution of the units wheel 47, one step of movement being synchronous with the movement of the tens wheel 36 of the conventional unit, and the other as the standards units wheel 23 is moving from 4 to 5. From this, it will be evident that the tens wheel of the dummy unit moves twice as fast as the tens Wheel of the standard unit.

The tens wheel 48 is provided with a hub portion 64 similar to the hub 33 on the tens wheel 30 and each of the hubs are provided with a pair of cam risers. The

cam risers

55 and 86 on the hub 33 are diametrically opposed and so positioned with respect to the numbers on the tens wheel 38 that they will strike a plunger 87 to move a pivoted switch member 68 when the numerals on the tens wheel visible through the window 22 are moving from a to 5 and from 9 to 0. Movement of the pivoted switch member 63 by the cams will cause the switch to close with the fixed switch member 83. The pair of cam risers 1G and ll on the hub G4 oi the tens wheel 38 are so positioned with respect to the tens wheel 58 that the cams on the hub 33 and those on the hub 64 will be in alignment when the counting wheels are returned to "0 position. Cams 10 and 'H are designed to actuate a plunger 72 connected to a pivoted switch member 13 to cause the member 13 to close with a fixed switch member II.

From the above it will be evident that rotation of the counting wheels will cause the cams on the respective units to operate switches at certain predetermined intervals. The switches are enclosed in circuits which will be described later. Before proceeding with the description of the various control circuits of the machine, the operation of the counter and the sequence of closing the switches controlled thereby will be described.

Each time a bill is inserted between the feed rollers in one of the compartments, the totalizer coils 15 will be energized through circuits to be described causing the armature 16 to move, operating the lever 71 by means of suitable linkage to impart an oscillatory movement to the shaft 23. The movement of the shaft will be imparted to the yoke 24 which is part thereof and that movement will likewise be given to the yoke 55 of the dummy unit which, as described, is tied to the yoke 26. Movement of the yokes 24 and 5 will cause rotative movement of the driving wheels 3| and 5| by means of the dogs 39 and 53, respectively, to impart to the respective units wheels one step of rotation. The subsequent insertion of other bills between the feed rollers of the machine will cause the units wheels to move forward additional steps. When the units wheel 29 of the conventional unit has reached a position where the numeral 4 shows through the totalizer window, the dog 53 will drop into the notch 52 in the wheel 5| so that the dog 59 may engage the teeth on the tens wheel drive wheel 52. Upon the next forward movement of the units wheels, the tens wheel 58 or the dummy unit will also be advanced one step. Thus it will be seen that the tens wheel or the dummy unit has moved one step while the standard unit registers 5. The units wheels continue their step-by-step movement until the units wheel of the conventional unit shows "9 through the window. At this point in the operation, dog 39 will drop into the notch 55 in the driving wheel 3| of the standard units wheel 29, and dog 58 will drop into notch 33 in driving wheel 5! for the dummy units wheel 41. Upon the next operation, both units wheels and both tens wheels will advance one step. It will now be seen that the standard unit will register 10 and the du.. my unit, although it has no numerals marked thereon, has advanced to the point where it would register "20, if it had such numerals, for although the dummy units wheel has made but one revolution the tens wheel of that unit has advanced two steps. The above operation is repeated so that the standard unit registers and the dummy unit has moved in an amount equal to 40. After another half revolution of the units wheels, the dog 53 will again drop into the notch 52 in the driving wheel 5!, so that upon the next movement of the counter the tens wheel of the dummy unit will be again moved. This next movement will bring the dummy tens wheel to the position where it should register 5 so that on that movement the cam '19 will strike its plunger 72 closing the switch members 13 and "i4. Upon completion of this movement, the standard counter will have its tens wheels still registering 2 and the units wheel having made a half revolution will register 5, so that the initial closing of switch l3, I4 is accomplished when the standard unit has registered a count.

An additional 25 count will bring the standard unit to such position that it cam will operate the plunger 61 to close the

switch member

68 and 69, and the dummy unit will have reached a position equivalent to 100 count, so that its cam II will again operate the plunger l2 to close the

switch members

13 and 14. It will be quite apparent from the above that at a 75 count on the standard unit the dummy counter will close its switch a third time, and at a showing of on the conventional counter, both the conventional counter and the dummy counter will operate their respective switches simultaneously.

Thus, there is provided a closing of the

switch members

68 and 69 at the counts of and 00 on the standard counter and a closingof the

switch members

13 and 14 at the counts of 25, 50, 75 and 00 on the standard counter. Although both switches are closed at counts of 50 and 00 on the standard counter, the switches are so arranged in the circuits which will be described that the operation of the device is, in effect, that which is conventionally shown in Figure 11 of the drawings, namely, the operation of a switch bya counter for each quarter revolution of the tens wheels.

In connection with the totalizer switches, there is employed a manually operable selector switch 18 which is of well-known type and comprises a pair of switch arms 79 and 80 and a central movable member 8l, which may be a single arm movable into contact with either the arm 19 or arm 80, or, as shown, may comprise a pair of spaced arms connected to a common lead with the arms being movable by means of the cam 82 controlled by a knob 83 to make contact with either the arm 19 or the arm 80. lhe switch is provided with a dial 84 to be positioned on the face of the machine and the knob 33 may have a pointer to facilitate the setting of. the switch, so that the machine motor may be stopped at the count of 25, 50 or 100 at the will of the operator.

By referring to the electrical diagram, Figure 13 of the drawings, it will be seen that a pair of piece-counters l4 and their operating mechanisms have been diagrammatically shown, as is the totalizer 20, the motor 9, the motor brake mechanism 85, double bill relay 85, piececounter l00-count relay 8?, shelf-dumping solenoid 83, a pair of latch relays 89 and iii operable in connection with the totalizer, and a control relay 9! for controlling the operation of the piece-counters and totalizer.

The connections to, and operation of, the piece-counters, totalizer and control relay are similar to those described in detail in Patent No. 2,429,159, and it will sufiice to say that current is supplied for operating these various units from one side of the line 92, to the piece-counter coils of that particular compartment where a bill has been inserted between the feed rollers, to close the switch 13, which current then passes from the piece-counter coils and through contacts on the control relay 9: to the return wire 93. As described in the above-mentioned patent, current flowing through the piece counter coils will cause the armature between the pole pieces to move closing the switch 94 which sets up a circuit through the totalizer coils 15, which circuit includes normally closed contacts of the control relay 9 I. Energizing the coils of the totalizer causes a closing of switch 95 completing a circuit through the coil of the control relay 9! which causes the normally closed contacts forming part of the circuits tothe piece counter and totalizer coils to be broken, allowing these counter to return to inoperative position, and, at the same time, set up a holding circuit to maintain the control relay in this position so that the counters cannot again be actuated until after a bill has passed from between the feed rollers of the compartment, all as described in detail in the abovementioned patent.

When the piece-counter of any particular compartment has completed a count of 100, a switch 96 is caused to be closed, energizing the coil of the piece-counter -count relay to break the motor circuit and apply the motor brake. The motor circuit includes the wire 92 to the point 91, wire 98, normally closed contacts 99 of the double bill relay 86, wire I89, normally closed contacts Hit of the piece-counter 100- count relay 81, wire Hi2, normally closed contacts Hi3 of the latch relay 90, wire :04, motor 9, wire N35 to the return line 93. Thus, it will be seen, upon the count of 100 on any of the piece-counters, relay 8'! will be energized separating the contacts H3! and breaking the motor circuit. The same will be true when two or more bills are accidentally fed to the rollers at one time so that the switch N36 is closed in the manner described in the Patent No. 2,425,318, which causes the relay 86 to be energized and the contacts 99 to be separated as will be explained. Contacts I03 will be separated to break the motor circuit upon totalizer counts of 25. 50 or 100, as the machine may be set.

When relay 8% is energized by a double bill passing between the rollers, contacts Ill! Will be closed setting up a circuit to the motor brake through wire 92 to point Hi8, wire m9, contacts lQl, wire H0, brake magnetic coil HI and the wire H2 to the return wire 93. Substantially the same circuit is employed when piece counter ARV-count relay 8'. is energized the current flowing through wire W9 to H3, contacts il i of relay 8'! and wire H5, into wire H0 leading to the brake coil. All of these operations are described in complete detail in the previously mentioned patent and it is not thought necessary to provide further description here.

When it is desired for the machine to stop at 10%) count on the totalizer, knob 83 of the selector switch is turned so that the arrow upon the knob points to the numeral 100 on the dial, at which setting the movable arm 8| will be in neutral position, out of engagement with both the arms 19 and 853. With this setting switch members 2'3 and it, operated by the dummy unit of the totalizer, are not in the circuit. Consequently, a circuit will only be closed when

switch members

68 and 69 operated by the cams on the conventional counter unit are closed. As previously described, these switch members will be closed when the totalizer registers 50 and 00. The first closing, of course, will come at the 50 count whereupon a circuit will be closed comprising wire 92 to point H6, wire H! to point H8, wire H9,

switch members

68 and 65, wire 52%, latch coil i2! of relay 89, wire I22 and wire I23 to the return line 33. The closing of this circuit will energize coil 2| drawing the latch i2 l to release the armature of relay 89 and this armature will drop closing contacts I25 and preparing a circuit to be closed upon the next closing or"

switch members

58 and 69. This second closing of the switch members will occur when the counter shows 00 which is at a count or" 100. There is then a circuit including wire 92' to point H8, wire I ii to point H8, wire II9,

switch members

68 and 69, wire I to point I26, wire I21, contacts I which are now closed, wire I28, wire I to latch coil "I3! of relay SE; and wires I32 and I23 to return line as. Energization of coil I3I will retract the latch !33 allowing the armature of relay 9?,- to drop separating contacts I 33, thus breaking the motor circuit. When the armature of the relay to falls, contact is made at I34 establishing a circuit to the brake which is im 'mediately applied to prevent overrunning of the motor. This circuit comprises wire 92 to point 91, wire 98, contacts Q9, wire I08, contacts IIlI, wire I62, the now closed contacts at 34 and wire I35 to wire III], brake coil III, wire II2 and return wire as.

After this operation, the motor remains stationary until

relays

89 and 90 are reset. The resetting of the relays is tied into the operation of dumping the shelves, as fully described in Patent No. 2,429,159, so that dumping of the shelves resets the two relays and starts the motor, the circuit being such that the shelves cannotbe dumped except at such time as the

relays

39 and 90 have operated to stop the motor. The circuit to the shelf dumping solenoid includes wires 92, Ill, switch I35, solenoid 88, wire I31, contacts I38 of the relay 9!} and wire I39 to the return wire 93. When solenoid B8 is energized contacts I40 are closed which establishes a circuit through wires 92, ill, to point I4I, wire 142, contacts E40, wire I43 to the branch wires 144 and I45 leading t the coils 89 and respectively, and from these coils through the wires I46 and I41, respectively, to the wire I39 and the wire I43 to the return wire 93. Thus, closing of the contacts I40 will energize the

coils

89 and 90, drawing up their respective armatures, and the latches I24 and 133 by the pull of their springs I49 and I5!) will engage the armatures and hold them in their lifted positions.

If it is desired that the operation shall cease at a count of 59 on the totalizer, selector switch 18 is so set, which will place the movable arm 8| in engagement with the contact I9. In this position of the elements, when the conventional unit of the totalizer reaches a count of 50, the

switch members

68 and 69 will be closed, setting up a circuit which includes wire 92 to the point H6, wire II? to point II8, wire II9 to switch members 53 and 59, wire IZB to point I51, wire I52, switch members 5E; and iii, wires I53 and sec, latch coil iSI of relay cc and wires I31! and I23 to the return line 93. Thus, it will be seen that upon each closing of the

switch members

58 and 59, relay 95 will be operated so that the contacts Hi3 will be opened to interrupt the motor circuit. Relay will operate as before, but this has no effect upon the operation of the relay so.

If it is desired to stop the machine at each 25 count of the totalizer, the selector switch 78 is turned to that setting, whereupon the movable arm 8! will be in contact with the switch arm 8 For the first time, closing of switch members is and '54 will have an eifect upon the operation of the machine. When these switch members are closed, a circuit is set up including wire 82 to point He, wire ill to point 354, wire I55,

switch members

13 and 14,

wire switch members

86 and 3!, wires I53, and E30, latch coil l3! of relay 9!] and wires i32 and to the return line 53. In this manner latch I 33 will be withdrawn, and the armature of relay Q0 will drop, interrupting the motor circuit and applying the motor brake at each 25-count on the totalizer. This will occur when the totalizer registers 25, 50, and 00. At the counts of 50 and 100, the conventional unit of the totalizer will operate to close the

contacts

68 and 69, which are still in the circuit controlling the latch coil I2| of relay 89 when the counter registers 50 and 00, but as the operation of relay as is merely to prepare a circuit to the relay 9!} for counts of 100, its operation in unison with operation of relay 9B does not efiect the desired result.

While in the above, there has been described one practical embodiment of the invention, it will be apparent to those skilled in the art to which this invention appertains, that many changes from the precise structure shown and described may be made without departing from the appended claims.

In mechanical counting mechanism, a pair of counter units mounted upon a single shaft, each unit comprising a units wheel and a tens Wheel, a toothed actuating wheel for each units wheel and tens wheel, identical means to impart rotative movement to the units wheel of each pair simultaneously and in equal increments including a dog mounted upon a rock shaft for engagement with the toothed actuating wheel for said units wheel, a second dog on each rock shaft in the plane of the toothed wheel for the tens wheel, said second dogs being normally positioned out of engagement with the said toothed wheels, a notch in the toothed wheel of the units wheel of one of said units to receive the actuating dog and permit the second dog on the rock shaft therewith to contact the toothed wheel of its tens wheel to transfer movement from said units wheel to said tens wheel, said toothed wheel of the unit wheel of the said other unit having a pair of diametrically opposed notches whereby two steps of movement may be transferred from the units Wheel to the tens wheel during a single rotation of the units wheel, and means operable by the tens wheel of each unit at least once during the revolution of each such wheel, whereby counts may be made at predetermined positions of said first mentioned unit and fractional multiples of the count may be made at predetermined positions of said second mentioned unit.

2. In mechanical counting mechanism as claimed in claim 1, said means operable by said tens wheels comprising a cam having two raised portions at diametrically opposed points fixed to each tens wheel, the cams of the tens wheels being identically positioned as to their respective tens wheels, and a switch in the plane of each cam adapted to be closed when struck by the raised portions of its respective cam, whereby one switch will be closed when its tens wheel reaches predetermined counts and the other said switch will be operated simultaneously with said first switch and at times intermediate thereto.

3. In mechanical counting mechanisms a pair of counter units mounted upon a single shaft, each unit comprising a pair of rotatable counter wheels, actuating means to impart rotative movement to one wheel of each pair simultaneously and in equal increments, means to transfer movement from the said one wheel of one unit to the other wheel thereof operable once each revolution of the said one wheel, means to transfer movement from the said one wheel of the other said unit to the other wheel thereof operable twice during a single revolution of the said one wheel, a cam carried by each unit having two raised portions thereon at diametrically opposed points, said cams being movable with the other said wheel of each unit, the cams of the units being identically positioned as to their respective units, aswitch in the plane of each cam adapted to be closed when struck by the raised portions of its respective cam, whereby one switch will be closed when its counter unit reaches predetermined counts and the other said switch will be operated simultaneously with said first switch and at times intermediate thereof. 7

4. In mechanical counting mechanisms a pair of counter units mounted upon a single shaft, each unit comprising a pair of rotatable counter wheels, actuating means to, impart rotative movement to one wheel of each pair simultaneously and in equal increments, means totransfer movement from the said one wheel of one unit to the other wheel thereof operable once each revolution of the said one wheel, means ment and the tens wheel receiving movement transferred therefrom, a cam having two raised portions at diametrically opposed points fixed to each tens wheel, the cams of the tens wheel being identically positioned as to their respective tens wheels, and a switch in the plane of each cam adapted to be closed when struck by the raised portions of its respective cam, whereby one switch will be closed when its tens wheel reaches predetermined counts and the other said switch will be operated simultaneously with said first switch and at timesintermediate thereto.
