Definitions

  • a register has a plurality of groups of decimally related number wheels which are driven during a dispensing operation to indicate the quantity and cost of a commodity being dispensed.
  • a resetting mechanism functions to un couple the wheels from the driving means, to reset the wheels to zero, and then to recouple the wheels to the driving means, in response to the rotation of a reset shaft in one direction through a portion of a revolution, followed by the rotation of this shaft in the reverse direction back to its original position.
  • the reciprocatory rotation of the reset shaft is effected by means of a reset motor which typically also effects other resettiiig an'cliadjustment or setting operations in a selective dispensingapparatus.
  • REGISTER RESETTING MECHANISM This invention relates generally to registers or counters, and more particularly to an improved resetting mechanism for a register.
  • the invention may be thought of as an improvement over the mechanism disclosed in Bliss, U.S. Pat. No. 2,814,444.
  • the invention has particular application to counters or registers employing a plurality of groups of indicating wheels (number wheels) and wherein, if desired, more than one quantity may be counted or registered.
  • a typical example of the use of such a register is in the gasoline dispensing field where it is desired to register both the quantity of gasoline dispensed and the cost thereof.
  • the number wheels of g the register are adapted to be driven by a meter, a change speed mechanism set in accordance with the prevailing price per gallon being employed to provide the proper ration between the drives to the cost and quantity wheels.

No. 850,901 filed Aug. 18, 1969.
  • one of the operations which must be effected is the resetting of the indicating wheels of the register, so that they will be at zero before the start of each dispensing operation.
  • the resetting of the register wheels is begun during an OFF cycle, following one dispensing operation, and is completed during the next ON cycle, before the next succeeding dispensing operation.
  • An object of this invention is to provide a novel motorized or powered resetting mechanism for a register.
  • Another object is to provide a powered register-resetting mechanism which is relatively simple as compared to prior powered or motorized resetting mechanisms.
  • a main reset shaft for the register is rotated, by a reset motor in the dispensing apparatus, through an angle of 90 in one direction during the OFF" cycle of the resetting and adjusting operation, and through this same angle, but in the reverse direction, during a following ON cy cle.
  • a cam arrangement on the reset shaft causes declutching of the number wheels of the register from the driving means which drives them during the dispensing.
  • a one-way clutch operated by this shaft causes resetting of the number wheels to zero, and during the latter portion of this ON” rotation the cam arrangement previously mentioned reclutches the number wheels to their driving means.

  • the said differential is the output unit of the gearing arrangement previously mentioned, and described in detail in my aforementioned application; the arrangement is such that the unit wheels of the group of cost wheels C and C will be driven in unison at a speed commensurate with the price of the quantity of gasoline being dispensed.
  • Each of the number wheels of the groups of cost wheels C and C is provided about its periphery with indicia consisting of the numerals zero to nine inclusive, and it is the intention that for each complete revolution of a number wheel of lower order, the wheel of next higher order will be rotated one-tenth revolution.
  • the transfer mechanism for transferring the count from the wheels of lower order to the wheels of higher order is quite conventional and forms no part of the present invention; therefore, it will not be described herein.

  • gears 62 62 on opposite ends of shaft 34 which engage idler gears 64, 64' which in turn mesh with the driven gears 42, 42' of the number wheels of lowest order of the quantity wheels.
  • the shaft 34 is rotated by means of a bevel gear 66 fixed intermediate the ends of shaft 34 and meshing with a bevel gear 68 shown in phantom in FIG. 1 and which is mounted on a shaft driven without any variable speed change by the output of a summing differential (not shown).
  • a summing differential which receives inputs from two meters, through which are passed respectively the two gasoline blending components dispensed, these two meters being rotated thereby respectively in amounts commensurate with the quantitles of the two respective gasoline components dispensed.
  • the summing differential mentioned is utilized to drive the quantity register directly, while the drive to the cost register is through the gearing arrangement (including the variator and another differential, previously mentioned) which changes the speed of rotation in accordance with the price per gallon of the particular grade of gasoline being dispensed.
  • the means to transfer the count of the wheels of lower order to the wheels of higher order in the groups of wheels 0, Q whereby each wheel of higher order will be rotated onetenth revolution for each complete revolution of the preceding wheel of lower order is the same as in the case of the cost wheels, previously mentioned.
  • the supporting shafts l4, 16, I8, and 20 although mounted for axial shifting movement, are retained against any rotational movement by pins 123 (see FIGS. 1 and 2) fixed on the outer ends of the shafts and slidably received between ears 125 formed in the side plate of the frame.
  • each of the gears 106 is meshed with one of the gears 124 which are fixed to transverse shafts 126, 126'.
  • the shafts 126, 126. protrude through the side plate 10 shown in FIG. 2 and are provided at their outer ends with pinions 128 which mesh at opposite sides with the spur gear 130 which is rotatably mounted on the main reset shaft 132.
  • the primary resetting gear 130 is turned by the reset motor 22 (FIG. 1), during its ON cycle of operation, in order to reset all of the number wheels to zero in one operation.
  • the shifting of the wheel-supporting shafts 14, l6, l8, and 20, in order to condition the register for a resetting operation by declutching the number of wheels from the driven gears 42, 42, or to recondition the register for a registering operation by reclutching the number wheels to the driven gears, is accomplished by a mechanism disposed on the exterior of the opposite side plate 10 shown in FIG. 3.
  • the cam portions 134a and l34b are arcuate, with centers at different respective points which are both eccentrically located with respect to the center of shaft 132.
  • the cam portion 1340 may also be arcuate, but centered at the center of shaft 132.
  • the rise direction of surface l34b is counterclockwise, while that of surface 1340 is clockwise, both as viewed in FIG. 3.
  • the cam 134 cooperates with a pair of rollers 136 and 24 mounted on a slide 138 slidably mounted at its opposite ends on ears 140 provided on the side plate.
  • the end of the main reset shaft 132 opposite to cam 134 is provided with a coupling 154 for receiv ing one end of a drive shaft 156 which is mechanically coupled through a suitable linkage indicated at 158 to the crank arm of a crank 160 driven by the reset motor 22.
  • the arrangement is such that, during the OFF cycle of reset motor operation which follows each actual dispensing operation, the main reset shaft 132 is rotated 90 counterclockwise viewed as in FIG. 2; during the "ON cycle of reset motor operation which precedes each actual dispensing operation, the main reset shaft 132 is rotated 90 clockwise (viewed as in FIG. 2) from the just-mentioned counterclockwise position.
  • the main reset shaft 132, and also the cam 134 are rotated 90 in the clockwise direction during the "OFF" cycle of reset motor operation, and during the ON cycle of reset motor operation, and during the ON cycle of reset motor operation, shaft 132 and cam 134 are rotated 90 in the counterclockwise direction from the just-mentioned clockwise position.
  • the cam 134 is illustrated in its ON" or re gistering position, that is, in the position it takes at the end of the ON cycle of reset motor operation, just before the actual dispensing begins.
  • cam 134 As cam 134 is turned 90 in a clockwise direction (from its FIG. 3 position, during the OFF" reset motor cycle, at the end of an actual dispensing operation), the camming surface 134a will come into play and move the slide 138 to the left by action of the surface 134a against the roller 136, the decreasing radium of surface l34b as the cam moves in this direction allowing the roller 24 to move to the left as viewed in FIG. 3, along with the slide. It may be noted here that the radius of surface 134a increases as the cam moves in this clockwise or OFF direction.
  • An arcuate notch or cutout 135 (of constant radius and having approximately radially extending end walls, in the material of the cam) in the cam 134 accommodating a stop 137 projecting from the frame limits the angular rotation of the cam 134.
  • the opposite ends of the slide 138 are formed with notches 142 for accommodating and engaging the tails of pawls 144 which are fixed to upright shafts 146 journaled as at 148 at opposite ends of the side plate.
  • the extremities of the shafts 146 are provided with gear segments I50 meshing with a series of circumferential teeth 152 on the adjacent protruding ends of the wheel-supporting shafts I4, 16, 18, and 20. Consequently, when the main reset shaft 132 is in the position shown in FIG. 3 of the drawings, which is the registering or "ON position, the wheel-supporting shafts 14, 16, 18, and are retained in the position shown generally in FIG. 1 of the drawings, the number wheels then being engaged with their respective driven gears 42, 42'.
  • the primary resetting gear 130 is rotatably mounted on the main reset shaft 132, between the coupling 154 and the side plate 10.
  • a drive plate 180 Fixed to the coupling 154 is a drive plate 180 which, by reason of such mounting, is adapted to turn with the reset shaft.
  • a notched disc 184 Located behind the drive plate 180 is a notched disc 184 which is fixed to the primary resetting gear 130.
  • the notched disc 184 is illustrated from simplicity as made integral with the resetting gear 130.
  • a drive pawl 200 Pivoted on the inner face of the drive plate 180 adjacent the periphery thereof is a drive pawl 200, the pawl 200 being pivoted in a clockwise direction into engagement with the notched disc 184 by a spring 202 opposite ends of which are attached to plate 180 and to pawl 200, respectively.
  • the direction in which the pawl 200 faces is such that, when the drive plate 180 is rotated in a counterclockwise direction during the OFF cycle as above described, the nose of the pawl 200 will merely ratchet over the edge of the notched disc 184 and will impart no movement thereto.
  • drive pawl 200 merely ratchets over the edge of disc 184, as previously stated; during this operation, no movement is imparted to the primary resetting gear or the notched disc 184, this being effectively prevented by the no-back pawl 204.
  • the no-back pawl 204 is cammed to a partial releasing position.
  • the drive plate has an abrupt camming edge 26 which is adapted to engage under a forwardly projecting pin 28 fixed to the no-back pawl 204, thus lifting the no-back pawl into the partial releasing position as the mechanism reaches the position shown in FIG. 5.
  • the notches 30 of the notched disc 184 have one corner thereof indicated at 300 cut away so as to render the notch more shallow on one side than the other. Accordingly, when the no-back pawl 204 is in full latching posi tion as shown in FIG. 2, movement of the notched disc 184 in either direction is prevented.
  • the notched disc 184 will be released for clockwise movement because of the shallowness of the notch at 30a, but will still be prevented from movement in a counterclockwise direction. It may be here noted that, to conform to the 90 back-and-forth rotation of drive plate 180 and pawl 200, the notched disc 184 (which, as will later become apparent, is driven intermittently in only a clockwise direction, in 90 steps) is provided with four notches 30, spaced at equal 90 intervals around this disc. With the apparatus in the position shown in FIG.
  • the plate-and-pawl arrangement 180, 200 comprises a one-way clutch for coupling together drive plate 180 and disc 184, since disc 184 is coupled to plate 180 only when the latter moves in the clockwise direction, even though the drive plate 180 rotates in both directions.
  • the mentioned concurrent movement of notched disc 184 will not be prevented by the no-back pawl 204 because, as previously mentioned, this pawl has been moved to releasing position by cam shoulder 26 drive plate 180.
  • the resetting of the number wheels takes place during the first 60 of the 90 ON rotation of the main reset shaft 132; as previously described, during the last 30 of the ON rotation of this shaft, the wheel-supporting shafts are shifted to reengage the number wheels with their driven gears, thus conditioning the register for a dispensing operation.
  • cam 134 shifts the wheel-supporting shafts 14, l6, l8, and 20 to declutch the number wheels from the driven gears 42, 42' and to coupled them to the ultimate resetting gears 106. in other words, the wheel-supporting shafts are shifted to resetting position.
  • the reset motor 22 automatically begins its ON cycle of operation, rotating the main reset shaft 132 through 90 to rotate cam 134 counterclockwise and drive plate 180 (FIG. 5) clockwise, the rotation of plate 180 being back to the FIG. 2 position. Since drive plate 180 when moving in a clockwise direction also drives the notched disc 184 through the pawl 200, this causes turning of the primary resetting gear 130, which movement automatically resets the number of wheels to zero.
  • cam 134 causes the shifting of the wheel-supporting shafts to registering position, so that the number wheels are reclutched to the driven gears 42, 42'.
  • the motorized resetting mechanism or powered resetting mechanism of this invention is quite simple in operation and in construction, as compared to the manually operated resetting mechanism of the cited Bliss patent. This is due primarily to the fact that a poweroperated mechanism, which operates independently of any human intervention, does not require the complicate mechanical interlocks and protective features which are necessary with a manually operated resetting mechanism, to prevent improper operation thereof.
  • a register a rotatable number wheel, a driven gear for rotating the number wheel during a counting operation, a resetting gear for resetting the number wheel to zero, shiftable means for connecting the number wheel selectively with the driven gear and the resetting gear, a shaft, a first means driven by said shaft for causing said shiftable means to connect the number wheel to the resetting gear upon rotation of said shaft in one direction, and a second means positively and directly driven by said shaft for causing rotation of said resetting gear in response to rotation of said shaft in the opposite direction.
  • said second means includes a one-way clutch operatively connected between said shaft and said resetting gear.
