11 Claims. 1
The present invention relates to registering or counting apparatus, and has particular utility in connection with counters or registers of the predeterminator type. ii'he invention has particular reference to an improved. arrangement of new and old elements whereby the driving, resetting and adjusting of the device is facilitated and whereby the functioning of the device is greatly improved.
While the present invention is applicable to register or counter mechanisms generally, it will be described more fully hereinafter, in connec tion with a predeterminator register of the type adapted to be used. with liquid dispensing apparatus, such as is described in my co-pending application Serial No. 701,923, filing date October 8, 1946. Such a device is characterized in general by two sets of number wheels, one of which sets registers the quantity of liquid dispensed and is manually resettable to zero, and the other of which sets is manually preset to show the quantity which it is desired to dispense, this set being returned to zero during the dispensing operation whereupon dispensing is automatically halted by the device.
It is a general object of the invention to provide a register mechanism of the type having presettable predeterminator counter wheel units and resettable registering counter wheel units in which there is a driving connection between the drive shaft of the register and the resettable registering counter wheel unit of lowest order and between said wheel unit and the presettable predeterminator counter wheel units of higher order such that during resetting of the resettable registering counter wheel units the registering counter wheel unit of lowest order will rotate independently of any movement of the drive shaft or the presettable predeterminator counter wheel units of higher order and in which there is a separate and adjustable driving connection between the unit wheels of lowest order whereby the operation of the register for the purpose of initiating an associated apparatus maybe adjusted.
It is a correlative more specific object of the present invention to so construct the resetting and driving mechanisms that the resetting of the first set of counterwheels to zero will in no way afifect the reading of the second set of counterwheels.
Another object of the invention is to so interrelate the driving and resetting mechanisms that damage to the device cannot occur by simultaneously driving and resetting, whether done inadvertently or purposely.
A further object of the invention is to provide a predeterminator counterwheel having means which is adapted, at certain settings of the counterwheel, to initiate the halting of an associated apparatus, which means is adjustable with respect to the drivin components of the wheel so that the means can be made to function at any desired setting of the wheel.
Another object of the invention is to accom' plish the foregoing objects with a construction which may be simply and easily manufactured and assembled and which will be sufficiently compact and rugged to provide improved operation of the device.
Other objects will be in part obvious and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

Referring to the drawings, and particularly Figs. 1 and 4, there is shown a predeterminator register mounted on a, frame comprising a. base plate l0 and side plates H and 12. The register is adapted to be driven, for example, by a meter (not shown in the drawings) which is operatively connected to the register through the gear train l3 positioned in the rear of the device. The gear train culminates in a bevel gear 14 fixed on a shaft [5 rotatably mounted on the side plates 1 l and I2.
As best shown in Fig. 2, the shaft l5 has a spur gear [6 fixed at one end thereto which is in mesh with a driven gear I! fixed to the first counterwheel unit |3 of the registering counter A, which unit I8 is shown in detail in Fig. 7. The first counterwheel unit |8 also has fixed thereto a second gear 20 which, through idler gear 2|, drives a gear 22 fixed to the first wheel unit 23 of the predetermining counter B. In the embodiment shown, this first wheel unit 23 is not arranged to be viewed and its function is to provide adjustable means for the purpose of operating the shut-off of the associated apparatus, such as a fluid valve or pump (not shown) as will be described more particularly hereinafter.
The counterwheel units (shown five) of the registering counter A hereinafter referred to as the registering counterwheel units are arranged in progressive order, the first unit l8 being adapted to register tenths, the second to register units, etc. The first registering counterwheel unit has indicia comprising /10 to 9/10, while indicia comprising the figures O to 9 are provided in the usual manner on the peripheries of the remaining wheel units to register with windows in the casing (not shown) whereby the setting of the wheels may be observed and read. Each of these counterwheel units is provided with the usual driving and driven gears 24 and 25 adapted to cooperate with the transfer pinions 26 mounted on a transfer pinion shaft 21 extending between the side plates and I2. Any suitable transfer mechanism may be utilized and the particular construction selected forms no part of the present invention.
The upper set of counterwheel units comprising the predetermining counter B hereinafter referred to as the predetermining counterwheel units comprises an equal number of wheel units, including the non-indicating wheel unit 23 previously referred to. All of the predetermining counterwheel units with the exception of the first unit 23 are provided in the usual manner with indicia ranging from 0 to 9. All of these predetermining counterwheel units are rotatably mounted on a shaft 28 extending between the side plates I and I2. In the completely assembled device, means (not shown in the drawings) is provided for presetting each of the wheel units separately for any desired reading, except for the non-indicating unit 23 which is continuously geared to the first registering counterwheel unit I8 and whose setting, therefore, is fixed thereby. Such presetting means is well known in the art, being usually comprised of individual presetting shafts and knobs adapted to cooperate with the bevel gears 29 respectively fixed to each of the predetermining counterwheel units. Any suitable presetting arrangement may be utilized and the particular mechanism selected forms no part of the present invention.
Each of the predetermining counterwheel units, with the exception of the non-indicating wheel unit 23 which is directly geared to the first registering counterwheel unit I8, as described above, is driven by a cam and ratchet arrangement more particularly shown in Fig. 3 of the drawings. As best shown in Fig. 3, a camming disk 30 secured to the registering counterwheel unit l8 and rotatable therewith causes a lever arm 3| to be reciprocated up and down for each turn of the counterwheel unit. The camming disk 30 is so arranged that the lever arm 3| is driven upwardly during the first half of a turn of the wheel unit l8 and permitted to return during the last half of the turn. The lower end of the arm 3| has a roller 32 adapted to rest on the periphery of the cam disk 33 to reduce the friction bfifi t the arm and the disk. The upper end of the arm 3| is pivotally connected to a frame member 33 which, in turn, is pivotally mounted on the shaft 23 supporting the predetermining counterwheel units of the predetermining counter B. Accordingly, the frame also is reciprocated up and down by the turning of the counterwheel unit I8.
Pivotally supported on a shaft 34 extending through the pivotal frame member 33 are a plurality of ratchet arms 35 which are adapted, re spectively, to engage ratchet wheels 36, one of which is fixed to each of the predetermining counterwheel units. Each of the ratchet wheels 35 is provided with notches 31 corresponding to the indicia on the number wheel, which notches are all of equal size, and a relatively deep notch 38 positioned for engagement with the ratchet arms 35 when that particular counterwheel unit registers zero. The ratchet arms 35 are disposed at relative angles decreasing in amount in sequence such that when one of the ratchet arms 35 is in engagement with a notch 31 of a counterwheel unit of lower order, the remaining ratchet arms 35 cannot engage the notches of the ratchet wheel or wheels of the counterwheel units of higher order. However, when the counterwheel unit of lower order has been regressed to zero, the notch 38 of that wheel, which then receives the corresponding arm 35, is sufficiently deep to permit the arm 35 for actuating the next counterwheel unit to be displaced into engagement with a notch of the said next counterwheel unit, thus functioning as a transfer device. The notches 38 being formed of sufficient depth so that all ratchet wheels are engaged by the ratchet arms 35 when the notches 38 are aligned, it will be apparent that during the reciprocation of the frame member 33 the turning of the predetermining counterwheel units to zero will be accomplished in a stepwise fashion, i. e., the wheel units are returned and come to rest at zero in sequence beginning with the wheel unit of highest order. As mentioned above, the driving of the predetermining counterwheel units is accomplished during the first half of each turn of the first registering counterwheel unit I 8 and remain stationary during the last half of the turn. In other words, a full count is registered by said wheels during substantialy one half count of the counterwheel unit Ill.
The lower end of the lever arm 3| which rests upon the cam disk 30 of the first registering counterwheel unit I 8 is positioned by an upright positioning member 4!) secured to the base plate H) of the frame by suitable screws 4|. The supporting member 40 has at its upper end a generally L-shaped slot 42 for receiving the flanged roller 32 on the end of the arm 3|. The supporting member 40 and the flanged roller 32 are so arranged that the flanges on the roller 32 by engagement with the sides of the slot 42 prevent any sidewise pivoting of the arm 3| thus insuring that the roller 32 will remain in alignment with the cam disk 33. The vertical portion of the L-shaped slot 42 permits the end of the arm 3| to be reciprocated vertically to cause the driving of the predetermining counterwheel units as previously described. As the direction of rotation of the cam disk 30 during registration is counterclockwise, looking at Fig. 3, there will always be a positive engagement between the cam disk 30 and the lever arm 3| during driving because the tendency of the lower end of the arm 3| to move or pivot toward the front of the register (due to friction between the arm 3| and cam situated between the arm 3| and theframe member 33. When the cam disk 30 is turned :in a reverse or c'lockwise direction, which occurs when the registering counterwheel units are being reset to zero, the lower end of the lever arm, which will now tend to move or pivot inwardly of the register, ridesoutwardly in the L shaped slot '42 and, therefore, will not be reciprocated up and down. In this -way; no motion is transmitted to the frame member 33 during resetting of the registering counterwheel units and, consequently, there is no resultant turning of these units and no effect upon there'ading shown thereon.
' As referred to above, the first registering counterwh'eel :unit I8 is rotated by a driven gear [1 fixed theret'o' and it, in turn, drives the first predetei'rnining counterwheel unit 23 (the nonindicating wheel) by a smaller or second gear fixed thereto. The construction of the-first registering counterwheel unit F8 is best shown in Fig. 7. Referring to Fig. '7, it will be observed thatthe counterwheel unit 18 comprises a num'- ber wheel having a hub 5| with a relatively small central opening 52 at one end to'accommodate the main portion of the resetting shaft v to cause it to turn and thus advance the second registering wheel 'unit one number for each turn of the unit wheel l8. The resetting shaft 53 contains an annular groove 59 for receiving a pawl 50 pivotally mounted in the hub 5| of the number wheel 50 and urged toward the shaft by a spring member 6|. When the resetting shaft 53 is pushed inwardly, the pawl 60 rides laterally out of the annular groove 59 and is held on the outer periphery of the shaft 53 unless or until such time as the shaft is rotated to align the longitudinal resetting groove 82 therewith, whereupon the pawlfiil pivots into engagement with the groo've'62 and thenumber wheel 50 becomes, in effect, :keyed :to the resetting shaft 53 and may be reset thereby tozero.
The driven gear 11 is rotatably positioned on the hub 5! at the end having the enlarged opening 54 and a connection is made between this gear and the number wheel '50 by means of a pressure .plate 63 which is slidably keyed to the hub 5| so that it rotates therewith but is longitudinally slidable thereon. The plate 63 is urged laterally intoo'ontact with the driven gear (I by a relatively strong spiral spring 64 extending between the plate 53 and a shoulder '65 on the hub'5l of the number wheel 50. When the resetting shaft 53 is pushed. inwardly.v as when it is intended to reset the number wheel units, the boss on the shaft 53 engages theypressure plate 1'63 and moves it laterally inwardly against the pressure of the spiral spring 54, thereby disengaging the number wheel 50 from the driven gear H so that the number wheel is free tobe reset to-Zero by turning the reset shaft 53. .-A1though the resetting shaft 53 isnot intended to rotate the numberwheel 50 until the pawl is engaged in the longitudinal resetting groove 62, it has been found that there frequently is sufficient friction between hub 51 and/or the pawl 50 and the periphery of the resetting shaft 53 to cause the number wheel 50 to be rotatedbefore the pawl 60 becomes aligned and engaged with the resetting groove 62. This tendency of the number wheel to rotate prematurely has been avoided in accordance with the invention by providing a second pressure plate 66 slidably keyed to the hub 5| so that it is rotatable therewith but slidable longitudinally thereon, which plate is adapted to frictionally engage the driven gear I! on the face opposite to that engaged by the first pressure plate 63. In the specific embodiment shown, the pressure plate is between the driven gear I! and the smaller driving gear 20 which is also slidable longitudinally on the hub 5| of the number wheel, this pair of elements (plate 66 and gear 20) being urged toward the driven gear 11 by a coil spring 61 supported on a flanged collar 68 retained on the hub 5| of the wheel by the retaining rin 59 received in an annular groove 15 in the hub. Thefrictional engagement of the pressure plates 53 and 65 and the driven gear I! is facilitated by a pair of friction disks H therebetween. The pressure exerted by the spring 61 is relatively weak being just sufficient to overcome the friction referred to above without materially interfering with the resetting operation.
The predeterminat'or shown in the drawings is adapted to shut off or actuate a shut-off mech anism for an associated apparatus (not shown) through a reciprocal connecting arm 12. I The arm '82 is pivotally connected to a pivoted lever arm 13 which is attached at one end to a roller bar 14 comprising a series of rollers 15 adapted to respectively engage cam disks 16 on the predetermining counterwheel units of the predetermining counter B. The pivoted lever arm 13 is biased by a spring ll so as to force the rollers 15 upwardly against the peripheries of the cam disks 16. Each of these cam disks T6 is provided with a notch 18 for receiving the rollers 15 when the counterwheel units are returned to Zero during a dispensing operation. As will be apparent, when all of the notches78 are in alignment with the rollers 15, the lever arm 1.3 is permitted to pivot'under the influence of the biasing spring Tl thereby lowering the connecting arm l2 which is utilized to shut off the associated apparatus by any suitable connection thereto (not shown). Inasmuch as there is usually a brief time interval (due to inertia, for example) between the instant the notches become aligned and the associated apparatus becomes fully stopped, it has been found necessary to provide a notch I8 in the first predetermin'in counterwheel unit, i. e., the non-indicating wheel unit 23, which is somewhat in advance of the zero position, whereby the shutting off of the associated apparatus is initiated slightly before 'the desired quantity has been dispensed and whereby the actual shutting off of the associated apparatus is completed by the time the wheel unit 23 reaches zero position. As the amount of coasting'a'fter the shuttingolf'of the associated apparatus has been initiated, butbefore itwis completed, will vary widely in different installations, depending on the type of associated aphas been found impossible to select a fixed position of the notch 18 of the wheel unit 23 which in all installations will effectively cause the associated apparatus to become completely shut off at the exact instant when the desired predetermined number of units has been dispensed or counted.
Accordingly, in accordance with the invention, the counterwheel unit 23 has been constructed so that the position of the notch 18 is variable with respect to the position of the driven elements of the wheel whereby the same may be adjusted to fit any particular installation. The construction of the counterwheel unit is shown more particularly in Figs. 5 and 6. Referring to these figures, it will be seen that the counterwheel unit 23 is formed in two separate sections C and D. Section C thereof, which includes the cam surface '16 and a notch 18 therein for causing actuation of the roller bar, as previously described, is provided with a hub 80 which extends into a recess 8| formed in the second section D of the wheel unit. Section D of the wheel unit, which carried the driven gear 22 previously referred to, is formed with a slot 83 tangential to the periphery of the hub 80 in which is positioned a worm 84 for engaging teeth 82 formed on the hub 80. The worm 84 is positioned in the slot 83 by engagement of shoulder 85 in the slot with an annular groove 86 in the worm. A spring 81 is provided in the recess 88 to exert a longitudinal force upon the worm 84 to effectively overcome any tendency of the worm to turn because of vibration or the like. The end of the worm is formed with a slot 89 for receiving a suitable tool (not shown), such as a screw driver, by means of which the worm can be manually turned. Turning of the worm 84, by reason of its engagement with the toothed hub 80 of section C of the wheel, provides an infinite adjustment between the sections and D of the wheel unit whereby the notch 18 in the first section C may be positioned at any desired rotated point with respect to the driving mechanism carried by Section D of the counterwheel unit. If desired, suitable indicia (not shown) may be provided on the peripheries of the sections C and D adjacent the inner edges to facilitate the relative positionin of the sections by the operator.
Inasmuch as the visible predetermining counterwheel units are completely actuated during the first half turn of the registering counterwheel unit of lowest order I8 as previously described, it will be appreciated that the relative settings of the sections C and D of counterwheel unit 23 at least during the last half of a turn thereof will have no effect whatsoever on the driving and positioning of the visible predetermining counterwheel units. This is a material advantage giving a high degree of flexibility to the adjustment of the counterwheel unit 23.
The first registering counterwheel unit I8 described above and shown in Fig. "I of the drawings is disclosed and claimed in my co-pending application Serial No. 67,473, filed December 27, 1948, and the counterwheel unit 23 described above and shown in Figs. and 6 of the drawings is disclosed and claimed in the co-pending application of James B. Hoye, Serial No. 67,451 filed December 27, 1948.
The device constructed in accordance with the invention, as described above, will be seen to have many novel and useful advantages resulting in superior performance of the device and greatly increasing its usefulness. The simplicity and ease of manufacturing of the parts has been improved while, at the same time, the device is less susceptible to breakage or malfunctioning through improper usage of the device either inadvertently or purposely.
As many changes could be made in the above construction and many apparently widely dif ferent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
