Definitions

  • This invention relates to accumulators in general, and in particular to an accumulator of the continuous or creep carry type.
  • a number of creep carry accumulators are known in which the carry mechanism comprises epicyclic gearing which by its nature, has to be arranged to allow for the one gear ratio factor that is added to or subtracted from the revolution of the mechanism as a whole, owing to the rotation of the whole unit.
  • epicyclic carry mechanisms arrangements are made whereby during the carry one is deducted from the ratio and a 9 to 1 gearing is, for example, employed to obtain a 10 to 1 carry.
  • An object of the present invention is to provide a creep carry accumulator which can be employed to register values according to the decimal system, or according to the sterling system, or if desired, according to the avoirdupois weight system.
  • a further object of the invention is to provide an accumulator which, due to its construction can readily be manufactured and assembled, and which can also be made up from independent units of which each unit comprises one digital column. This feature is especially useful in a sterling accumulator, as, for example, in one instance it may be required to register values including farthing amounts, while in another instance values including only pence and shillings may be registered.
  • Still another object of the invention is to so construct each such unit that the actuator for that digital column remains unchanged whether the unit befor adding twelfths as in the pence column, tenths as in the units of shillings column, halves as in the tens of shillings column, or any other fractional amounts.
  • Another object of the invention is to make all of the units'thesame, the variable elements being contained in the inter-order connecting gearing.
  • each order of the accumulator an actuator, a differential cage meshing with the actuator, 21. pair of intermeshing planetary gears carried by said cage, a sun gear meshing with one of said planetary gears, a driving gear coaxial and rotatable with said sun gear, a resultant gear meshing with said driving gear, and a second sun gear rotated in accordance with the carry from lower orders in mesh with the second of said planetary gears.
  • the invention also contemplates the use of visible dials to indicate the amounts registered in the several orders of the accumulator, and where such dials are utilized means are provided to ensure that fractional carry amounts are not registered thereon.
  • One other object of the invention is to so construct and arrange the dials and the carry repressing means as to prevent carry amounts from being indicated on the dials, simply and efii-' ciently, even though said amounts be registered on the resultant wheels of the accumulator.
  • Fig. 1 is a side elevation, partly in section, of a statistical machine having the invention applied thereto;
  • Fig. 2 is a plan of part of the accumulator in: dicated generally in Fig. 1 by the reference letter A, the denominational order units being shown diagrammatically;
  • Fig. 3 is a side elevation of one of the accumulator units, some parts of the mechanism being broken away to show the integers normally hidden behind such parts, the unit illustrated being one employed for tens or hundreds of pounds;
  • Fig. 4 is a plan of the accumulator unit shown in Fig. 3;
  • Fig. 5 is a perspective View from the rear of one of the accumulator units, the parts being shown diagrammatically and in partial exploded disposition;
  • Fig. 6 is a section through the difierential gearing
  • Fig. 7 is a perspective view of a detail showing compensating mechanism for maintaining a figure on an indicating wheel in reading position.
  • each accumulator wheel 22 there is secured for rotation therewith a driving wheel 23 which meshes with an idler gear 24.
  • Each of the idler gears 24 meshes with peripheral teeth on a differential cage 25 (Figs. 3, 5, and 6) which is riveted or otherwise fastened to a flange 26 on a spindle 21 journaled in unit frame plates 28 and 30.
  • (Fig. 4) secured to the cage 25 has positioned therein two short spindles 32 and 33 (Fig. 3) on which are journaled a pair of intermeshing planetary gears 34 and 35, respectively, said planetary gears extending into apertures 29 in cage 25 (Fig. 3).
  • the intermeshing planetary gears 35 and 34 (Figs.
  • first and second sun gears 36 and 31, respectively also mesh with first and second sun gears 36 and 31, respectively, the first sun gear being fixed on a collar 38 loose ly mounted on spindle 21, and the second sun gear 31 being mounted on a collar 45 to be more fully described hereinafter.
  • a driving gear 41 meshing with a resultant gear 42 which, as will become apparent hereinafter, indicates by its angular position the total of the input and carry amounts accumulated in the denominational order of which it is a part, but which, in the present instance, in order to make said total visible, in turn meshes with a gear 43 fixed to an indicator dial by a sleeve 45 journaled on a spindle 46 (Fig. 7) carried in a bearing arm 41 pivoted at 48 to the frame plate 28.
  • gear 24 imparts units of rotation to cage 25, which, the second sun gear 31 being considered as fixed for the present, causes planetary gear 34 to roll around said sun gear.
  • the rotation of gear 34 rotates gear 35 and through it the first sun gear 36.
  • the bodily movement of gear 35 about the center of cage 25 also causes rotation of sun gear 36, so that the latter has imparted to it a multiple of the angular movement imparted to the cage by gear 24.
  • the ratios are such that planetary gears 34 and 35 multiply the movements of the cage by two, so that sun gear 36 and driving gear 4! which is fixed to rotate therewith, receive twice the angular displacement of the cage.
  • said resultant gear 42 has a reduction ratio with the driving gear equal to the factor by which the planetary gears multiply the movements of said cage, in the present instance 2 to 1, so as to compensate for the multiplication of cage movement by said planetary gears.
  • the indicator wheel 44 is preferably made with two sets of numerals and the gear 43, by which it is driven from the resultant wheel, is made with a number of teeth appropriate to allow a one tooth movement of the resultant gear to rotate the dial one digital space.
  • each resultant wheel 42 has a carry member 50 projecting laterally and engaging in a slot 5
  • driving gear 4! is, in the present instance, in the ratio of 1 to 2 with the resultant gear, which results in that the carry movements transmitted to the driving gear from the resultant wheel of lower order are halved in passing from said driving gear to the resultant gear meshing therewith.
  • the inter-order reduction gearing is provided with a ratio equal to half the carry ratio between the two orders.
  • the re-' duction ratio is 5 to 1, for twelfths it is 6 to 1-, for halves as between the tens of shillings and units of pounds orders his 1 to 1.
  • the second sun gear 31 instead of being fixed as assumed above, may be rotating due 'to a carry from the lower order, so that as planetary gear 34 rolls around said sun gear due to an input to cage 25, the rate of rotation of said planetary gear on its axis is momentarily increased.
  • the planetary gear pair multiplies the movements of cage 25 and transmits the carry at the same time.
  • each indicator wheel 44 is, as mentioned above, supported by a pivoted arm 41, which as presently to be described, permits of fractional counter rotative movements of said wheel.
  • the axis of the pivot 48 of arm 41 is located in the plane containing the axes of the resultant wheel 42 and the indicator gear 43 (Fig. 3).
  • a compensating cam 57 (Fig.
  • the gears operate as just described, but with the result that the tens of pounds indicator wheel is rotated a further five teeth to register an eight in the reading position and the resultant wheel of the hundreds of pounds unit is turned from zero and three tenths to zero and eight tenths, but the zero on the hundreds of pounds indicator dial remains in reading position.
  • the tens of pounds unit will be operated in the manner just described above in so far as the registration of the four is concerned, but while the cage 25 is rotating to eflect this registration the planetary gears 34 and 35 (Fig. 5) are being positively driven by the last gear 56 of the train of reduction gearing associated with the units of pounds column, with the result that the angular velocity of gear 4
  • the number registered on the indicator wheel of the tens of pounds unit at the end of this cycle is eight.
  • Any suitable means may be used to restore the accumulator to zero, that shown in the drawing being a preferred one. This means is fully disclosed in the copending application of Arthur Thomas, filed January 28, 1948, S. N. 4,765, but will be referred to briefly herein as an aid to an understanding of the present invention.
  • each resultant wheel 42 (Fig. 3) is provided with a plurality of equi spaced studs 63 for cooperation with a pawl 64 pivoted at 65 to an arm 65 itself loosely pivoted about the axis of the resultant wheel.
  • the angular spacing of the studs is determined by the amounts being registered on the resultant wheel, for example, if tenths are being registered, the studs are located in radial alignment with every tenth tooth space of the wheel, if twelfths are being registered, in radial alignment with every twelfth.
  • the pawl 64 is normally drawn into position for engagement with a stud 63 by a spring 6'! connecting the pawl with arm 66, but as the wheel rotates the studs cam the pawl outward in passing it.
  • the arms 66 are rocked counter-clockwise about their pivots in rapid succession beginning with the wheel of lowest order, while the machine is at rest.
  • the means for rocking each arm 66 include a rearwardly extending link 88 which is connected by another link 10 (Fig. 1) to a Geneva movement arrangement on a zeroizing shaft H which is rotated by hand at the appropriate times through a handle 12.
