Definitions

  • Counter units having number wheels which register a count are known, and in some units it is desirable to be able to supply a count input to at least two number wheels of the unit, rather than to follow the more normal course of supplying an input to only the endmost number wheel of a series of such wheels.
  • the requirement of being able to supply a count input to at least two of the number wheels arises, for example, in respect of counter units which register currency values.
  • a unit for registering pence and shillings and tens of shillings it may be required separately to acuate the number wheel allocated to shillings and the number wheel allocated to' pence, but it will be appreciated that a transfer action from the pence number wheel to the shillings number wheel is necessary once for each revolution of the pence number wheel.
  • Analogous considerations arise in connection with number wheels registering cents and dollars.
  • FIG; 1 is an elevational view, partly in section, of a counter unit having number wheels by which pence, unit shillings, tens of shillings, pounds, tens of pounds and hundreds of pounds can be registered;
  • FIG. 2 is a sectional view, partially broken away, along the line II-II of FIG. 1;
  • FIG. 3 is a sectional fragmentary View, along the line ⁇ IL-III of FIG. 1;
  • FIG. 4 is a sectional fragmentary view, along the line lV-IV of FIG. 1.
  • the counter unit illustrated comprises a base 1 carrying two spaced apart parallel side walls 2 and 3.
  • a shaft 4 is mounted between the side walls 2 and 3 and carries six number wheels 5, r6, 7, 8, 9 and 10 which are freely rotatable thereon.
  • Wheel 5 serves for registering pence, wheel 6 shillings, wheel 7 tens of shillings, wheel 8 pounds, wheel 9 tens of pounds and wheel 10 hundreds of pounds.
  • transfer pinions 13 which are freely rotatable on a'shaft 14 are provided for rotating number wheel 7, 8, 9 or 10 through one step when the preceding number Wheel 6, 7, 8 or 9 respectively has rotated through a complete revolution.
  • the arrangement of the transfer pinions is not shown in detail, since such transfer pinion arrangements are well known and are used in conventional stepby-step digital counting mechanisms.
  • the respective transfer pinions are driven by teeth pro- I vided on the respective succeeding number wheels.
  • the transfer pinions 13 are movable into a disengaged position, by means of the shaft 14.
  • the shaft 14 is mounted between rocker levers 15 which are pivoted to the Wall 3, which bearing directly engages the shaft 42, and a Patented Mar. 29, 1966 side walls 2 and 3 by studs 16.
  • Each rocker lever 15 carries a stud 17 which engages in a cam slot 18 (FIG.
  • the number wheels When the transfer pinions 13 are disengaged from the number wheels, the number wheels may be rotated for resetting. Such rotation may be manually effected or may be effected by known resetting devices (not shown). Such known devices may comprise pawls which are brought into engagement with cams provided on the number wheels so as to rotate the cams and therewith the number wheels, into predetermined positions.
  • Number wheel 5 rigidly carries a toothed wheel 23 which meshes with a toothed wheel 24 fixed on a sleeve 25 rotatably disposed on a shaft 26 mounted between the side walls 2 and 3. Toothed wheel 24 meshes with a toothed wheel 27 carried by a hub 28 which is freely rotatable on a shaft 29 mounted between the side walls 2 and 3.
  • the hub 28 also carries a toothed wheel 31 and this is positioned for engagement by tooth members 32 of a drum arrangement generally indicated by reference numeral 33.
  • Number wheel 6 rigidly carries a toothed wheel 34 which meshes with a toothed wheel 35 freely rotatable on the sleeve 25. Toothed wheel 35 meshes with toothed wheel 36 which forms part of a sleeve 37 of which a toothed wheel 38 and a toothed wheel 39 also form part, the sleeve 37 being freely rotatable on the shaft 29. Toothed wheel 38 is positioned for engagement by tooth members 41 of the drum arrangement 33.
  • the drum arrangement 33 comprises a shaft 42 which is rotatably mounted by means of a bearing 43 in the side bearing 44 in the side wall 2, which engages an outer sleeve 45 of two concentric sleeves 45 and 46 disposed.
  • Sleeve 45 carries a knob 47 for rotation thereof and sleeve 46 carries a knob 48 for rotation thereof.
  • Sleeve 46 carries a flange 51 in which at least one detent ball 52 is seated, the ball 52 being urged by a compression spring 53 into detent engagement with a flange 54 fixed to the shaft 42 by a key 55.
  • vAnother flange 56 is fixed to the flange 54 by a plurality of spacing rods 57.
  • the sleeve 45 carries a flange 58 in which at least one deten-t ball 61 is seated, the ball 61 being urged by a compression spring 62 into detent engagement with the flange 56.
  • the spacing rods 57 slidably carry the tooth members 32 and 41, the said tooth members having pegs 63 which engage in cam tracks 64 and 65 formed in the cylindrical peripheries of the flanges 51 and 58 respectively.
  • the cam tracks 64 and 65 are so shaped that depending on the extent through which the knobs 47 and 48 are turned relative to the shaft 42 the number of tooth members 32 and 41 which have such an axial position as to be engageable with the toothed wheels 31 and 3-8, respectively, on rotation of the entire drug arrangement 33 by the shaft 42, can be varied. Accordingly, knob 47 serves for setting the number of pence which will be registered;
  • knob 48 serves for setting the number of shillings which will be registered on number wheel 6 for one revolution
  • a transfer pinion is not provided for effecting a transfer between number wheel and number wheel 6 when number wheel 5 has turned through one revolution. The reason for this is that difiiculties would be encountered if a transfer to number wheel 6 had to take place at the same time as a rotation of number wheel 6 by its direct input toothed wheel chain 34, 35, 3 6, 38, 41.
  • an arrangement having a storage action is provided for rotating number wheel 6 by one step, subsequent to any rotation of number wheel 6 by the toothed wheel chain 34, 35, 36, 38 and 41 from the drum arrangement 33, if during rotation of number wheel 5 from the drum arrangement 33, the number wheel 5 completed a revolution, that is to say moved from an indication of eleven pence to an indication of zero pence (1 shilling, it should be noted, equalling 1 pence)-
  • This delayed rotation of number wheel 6 by one step is effected through the toothed wheel chain 39, 38, 36, 35, 34.
  • toothed wheel 39 is rotated through one tooth space and this is done by means of an actuating drum 66 in which a lever member 67 having a single tooth 68 is mounted.
  • the lever member 67 is pivoted on a shaft 69 in the drum 66 and is urged by a compression spring 71 into its position shown in full lines in'F'IG. 1, that is to say the position in which its tooth 6 8 lies out of a path of engagement with the toothed wheel 39.
  • the drum 66 is keyed to the shaft 42 by a key 72, for rotation therewith.
  • the lever member 67 for the lever member 67 to be effective for engaging the toothed wheel 39 as it moves into the range thereof during one revolution of the shaft 4-2, the lever member 67 has to be moved into the position shown in broken lines in FIG. 1. Such movement of the lever member 67 is effected when during the preceding part of one revolution of the shaft 42 the number wheel 5 rotates from an indication of eleven to an indi cation of zero.
  • a cam 73 which is rotatably mounted on the shaft 29 and which has an oblique face 74 is encountered by the lever member 67 so as to deflect the lever member 67 to the right as viewed in FIG. 1, if the cam 73; has been moved into its effective position.
  • the cam 73 is mounted on a hub 75 which carries a wheel 76 having a step 77 (see FIGS. 1 and 3) and this step 77 is engageable by a single tooth 81 on a wheel 8% which is fixed to the sleeve 25.
  • the sleeve is rotated by toothed wheel 24 during rotation of the number wheel Sand the tooth 81 on wheel 82 is so positioned as to engage the steps 77 of wheel 76, whereby to rotate the wheel 76, during rotation of number wheel 5 from an indication of eleven to an indication of zero.
  • Rotation of wheel 76 rotates the cam 73, which is rigid therewith, and thus positions the cam 73 for engagement by the tooth 68 at the appropriate point in the rotation of the drum 66 by the shaft 42.
  • the lever member 67 is provided in the drum 66 at a region which, in terms of rotation, lags behind the regions of the drum arrangement 33 in which the toothed members 32 and 41 are provided.
  • the detent spring 83 has a bi-stable overcentre action with respect to the peg 84.
  • the detent lever 85 is rigid with a member 87 having a series of teeth by which it meshes with a member 88 having a series of teeth, the member 88 being rigid with the toothed wheel 76, hub and cam 73. Due to the meshing of the toothed members 87 and 88, the detent action provided by the spring 83 is effective for holding the cam 73 in its inoperative position, prior to engagement of the tooth 81 of wheel 82 with the step 77 of wheel 76, and for holding it in its operative position subsequent to this engagement.
  • the cam 73 After rotation of the drum 66 past a position in which the tooth 68 is caused to engage the toothed wheel 39, the cam 73 is returned to its inoperative position.
  • the toothed member 87 is provided with an extension 91 (see FIG. 4) which is engaged by a single fixed tooth 92 on the drum 66 during subsequent rotation of the drum 66 through the remainder of its revolution.
  • the number of pence to be added to the indication given by the number wheels is set by turning knob 47 to an appropriate position, and the number of shillings to be added to the indication given by the number wheels is set by turning knob 48 to an appropriate position.
  • the set pence and shillings amounts are then added to the indication given (by the number wheels by rotation of the shaft 42 through one revolution.
  • the actual adding of the set pence and shillings amounts to the indication given by the number wheels takes place and during a later part of the revolution, any transfer from the pence number wheel 5 to the shillings number wheel 6, occasioned by number wheel 5' having passed through an indication of eleven, is affected.
  • the invention has been applied to a counting-unit for currency values involving pence and shillings.
  • the invention is equally applicable to counting-units for currency values based on a decimal system or to counting-units for other purposes, where it is desired to provide for direct operation of at least two number wheels of the counting unit while allowing a delayed transfer action from one of the said two number wheels to the other.
  • a counter unit comprising a plurality of rotatable number wheels, first means for driving one of said plurality of number wheels for registering a desired count thereby, second means for driving another one of said plurality of number wheels for registering a desired count thereby, means for imparting a rotation to said other number wheel when said one number wheel passes through a predetermined position, means for rendering said rotation imparting means operative only after the driving of the said other number wheel by the said second driving means has been effected, said rotation imparting means comprising a lever, a tooth member on said lever, a toothed wheel, rotatably mounted cam means for engagement by said lever to move said tooth member into position for engaging said toothed wheel, a rotation-imparting member rigid with said cam means, said cam means being rotatable from an inoperative position into an engagement-clr'ective position by said rotation-imparting member, a wheel, and a tooth thereon, said rotation-imparting member being arranged for engagement by said tooth of said wheel which is.
