Definitions

  • counter mechanism units namely a product counter mechanism and a revolution counter mechanism, arranged in a circle round a cominon drive member and capable of being lifted out of tooth engagement by axial displacement and of being cleared (zeroized) either singly orv jointly;
  • the invention consists in the fact that the teeth of the zeroizeronthe one-hand, when the zeroizer is inits normal position span, Without engaging, the counter mechanism members arranged in the smallest circle structurally conceivable in order that during calculation said members may rotate unobstructedly, and on the other hand may be brought from the norm al position into engagement with all the counter-mechanism members,
  • the zeroizer is so designed that, at the beginning of its operation it automatically, by means of a control and looking device, lifts the oounter mech'anisms (product register and revolution register), which are capable of beinglifted out of engagementwith the setting mechanism, and retains them in the lifted position until zeroizing is completed.
  • oounter mech'anisms product register and revolution register
  • the zeroizer may, in accordance with the invention, be provided with a pivoting'handle no'parts of which project beyond the periphery of the machine when the latter is being carried in the coatpocket.
  • FIG. 1 shows the top of the pocket-Sizecalculating machine, highly enlarged inivertical section, along the line I I of Fig.2.
  • a i Fig. 2 shows a horizontal section along the line IIIIinFig.1.
  • Fig. 3 shows the top of a calculating machine, with the counter mechanism lifted, inside elevation, partly cut away.
  • Fig. 4 shows the machine in plan.
  • Fig. 5 shows the resetting member in vertical member.
  • Fig. 8 illustrates .the pin of Fig 7 in a position in which the handle is locked inoperative position to said re-setting member as shown in Fig. l.
  • Fig. 9 shows a view of the pin and re-setting member along line 99 of Fig; 7.
  • v Fig. 10 illustrates in detail the cooperation of a rack on the re-setting member with the transfer wheel of the counter mechanism, H

  • the handle an is provided at'the end with an extension 34 projecting from it at' an angle with a rather narrow, curved slot 35 the curve of which represents an arc of a circle whose centre is the pivotal point 3
  • Contiguous to the slot 35 is a round'aperture 36 the diameter of which is adapted to receive the pin or stud 32 and which is wider than the slot 35.
  • FIG. 7 shows the position occupied by the pinor stud '32 when the handle 30 is in the out-of-use position. If the handle 30 is pivoted to its position of readiness for'use, it embraces by its oblique surfaces 31, shortly before reaching the ready-for-use position, the taper shoulder 40 and forces the'pin or stud 32 downwards, against the action of the spring 33. As-the handle 30 completes its move ment the pin or stud 32 bears against the lower face 4
  • the pin or stud is forced, by finger pressure on the head 39, out of the aperture, 38 in a downward direction, the neck 38 being at the same time pressed into said aperture.
  • the shank 42 of the stud 32 which shank determines the depth of the-neck 33, is adapted to the s1ot'35, so that the handle 30 can be unobstructedly pivoted.
  • a main shaft rotatably mounted in a casing, a plurality of shafts arranged spaced and parallel to said main shaft and along a circular line concentric with the axis of said main shaft, said shafts forming the driving members of a product counter mechanism and revolution counter mechanism respectively, a pinion at the end of each of said shafts and adapted to mesh with a transfer wheel, an axially movable body rotatably mounted about the axis of said main shaft and having fixedly mounted thereon a plurality of radially extending axles, one for each of said shafts, said transfer axles and being each associated with a numeral wheel, a re-setting member rotatably mounted To give a 2 wheels being rotatably mounted on said radial on saidaxiallymovablebody and providedwith two curved serially arrangedre-setting racks adapted upon relative rotation- ⁇ with respectto said body to engage said transfer wheels, spring means for normally urging said body in an axial direction in which said

  • a pocket-size calculating machine in which some of said transfer wheels, namely the ones which in the rest position of said resetting member are arranged directly below said resetting racks, are provided with recesses into which said resetting racks extend without operatively engaging said transfer wheels, said resetting racks being arranged laterally offset lengthwise of their curvature, so that upon operation of said resetting member each of said racks engages the recessed transfer wheels which in the rest position of the resetting member are not engaged by the other rack to return the same to zero.
  • a pocket-size calculating machine in which the transfer wheels each have ten teeth and that one end portion of at least one tooth on said wheels opposite the zero numeral on the corresponding numeral wheels has been cut off, whereby said transfer wheels serve at the same time as resetting wheels.
