Definitions

  • the present invention generally relates to counters and the like and, more particularly, to a readout system of the type employing one or more figure drums or rollers, on the periphery of which there are arranged symbols, figures, letters or markings which are to be indicated or read.
  • the present invention is particularly adapted for reading-out symbols or the like at a location remote from the counter assembly which sends a control pulse or the like adapted to cause rotation of the figure drum into a position whereby the proper symbol or information transmitted can be easily read.
  • the present invention relates to a particularly simply controlled roller or figure drum which operates in the fol-lowing manner:
  • Each symbol or number firom zero to nine is characterized by a combination of four switch or indexing positions. Sixteen combinations are possible, and the teachings of the invention also permits it to be applied to non-decadic rollers. If further combinations are desired then the principle of the present invention permits of such deviation or amplification.
  • An easy manner of calculating the maximum number of symbols which can be handled with a particular combination of control cables or wires can be determined by the formula 3 :2 where x designates the number of control wires or switches associated in the control circuit between the sender and figure drum.
  • thirty-two combinations are possible which, accordingly, permit the transmission of thirty-two symbols or figures spaced about the periphery of the roller.
  • the ten combinations conform to ten templates or stencils which are concentrically arranged about the axis of the figure drum or roller in such a manner that each combination represents one figure on the periphery of the roller.
  • the templates may be, by way of example, cams which are able to engage four switches, or also slotted holes or slits through which light may fiall .upon tour photocells, or iurther, any other suitable devices by means of which an electric circuit may be closed.
  • Particularly suitable for this purpose is magnetic controlling device which operates, for example, in such a manner that the lines of force of a stationary magnet are screened or adjusted by means of one of the templates made of soft iron forming the plate or sheave portion of the roller.
  • Behind the template there are arranged four switches or the like which are able "ice to be magnetically actuated. Such occurs when during the constant turning of the figure drum a notch or cutout of the template is interposed between magnet and switch.
  • magnetic influenced vacuum switches the wear and tear is slight or negligible, so that a very long useful life of the arrangement results, while moreover, such magnetic switches are tree from the danger of causing explosions when working in atmospheres containing explosive gases.
  • the figure drums may advantageously be continuously driven in a manner known to the art via a friction or slipper clutch.
  • the ten templates glide in a continuous manner past the switching arrangement.
  • the sender transmits a particular combination through the four control lines to the figure drum or roller, a current will only flow through the control circuit when exactly that template which represents this particular combination is positioned in front of the switching device.
  • the current then energizes a suitable braking device which arrests the movement of the figure drum so long as such combination is present.
  • a reverse operation of the system is also possible such that the current for the braking means is interrupted thereby causing actuation of the braking device to carry out a corresponding braking of the figure drum.
  • the blocking or braking action can be accomplished, by way of example, by providing the roller with ten projections or indentions, each of which is associated with one of the symbols or figures and that a magnet attracts a locking pawl or the like which engages with one of the projection or indentations.
  • the exact manner in which input signals from a sender can control a switching arrangement in the receiver and circuitry suitable for such is well known to the art, one such possibility being described in United States Patent 2,676,289, invented by A. H. Wulfsberg et a1. and granted April 20, 1954.
  • a further object of the present invention is to provide means capable of handling the readout of a large quantity of symbols or the like in a safe and reliable manner, which means is of simplified construction and very economical in its manufacture.
  • Still further important object of the present invention is to provide a system for the readout of symbols or information transmitted from a remotely positioned sender, such as a counter assembly, which system permits indexing of a figure-drum to the desired read-out position by suitable switching elements which do not physically contact the figure drum.
  • Yet a further noteworthy object of the present invention is to provide a read-out system readily capable of processing large quantities of information in a quick and positive manner, which system is simplified in its construction and highly economical to manufacture.
  • Another important object of the present invention is to provide an improved arrangement for treading-out information employing one or more rotatable drum members carrying said information, and wherein a single brake member is provided for each drum member to arrest the latter in a desired read-out position.
  • FIG. 1 is a front elevational view of a first embodiment of the present invention illustrating a read-out figure drum controlled by photoelectric cells;
  • FIG. 2 is a side elevational view, partly in cross-section, of the arrangement shown in FIG. 1 and depicting two read-out figure drums arranged adjacent one another;
  • FIG. 3 is a further embodiment of the present invention showing a read-out figure drum, such as illustrated in FIGUR'ES 1 and 2, but employing magnetic switching means;
  • FIG. 4 illustrates still another embodiment of the present invention wherein the read-out figure drum uses small permanent magnets for actuating magnetic switches.
  • FIGURES 1 and 2 there is illustrated a first embodiment of a tread-out system for a counter or the like employing one or more figure drums 1 which are operated in conjunction with photoelectric cell means 3.
  • the figure drum or roller ii is constructed in the form of a template or plate 1a which supports at its outer periphery 1b a plurality of symbols or figures which are to be read-out. F or convenience in description, and by way of example, the numerals zero to nine are shown arranged at the peripheral surface of the figure drum 1, as best seen in FIGURE 2.
  • the vertically arranged plate or template portion 1a of the figure drum 1 is conveniently divided into a plurality of sectors 2 which correspond in number to the number of symbols or other information to be read-out.
  • sectors 2 which correspond in number to the number of symbols or other information to be read-out.
  • FIGURES l and 2 where the numerals zero to nine are being processed, ten such sectors are provided, with each sector containing a particular grouping or arrangement of cutouts or slots 2a.
  • the arrangement of the slots 2a for the ten sector groupings differ from one another, such that the collective slots 2a of one particular sector designates one of the symbols "to be read-out.
  • the slots 2a of each sector move past a suitable switching arrangement consisting of the four stationary photoelectric cells 3 and are lit-up by the lamp member 7a.
  • the electromagnetic brake means 4 supported by the bearing portion 12 of the support bracket 8 for the figure drum '1 becomes energized.
  • the braking means causes the locking pawl 5 to engage behind the associated locking cam surface or holding protrusion 6 provided for each of the sectors 2, with the result that the rotational movement of the figure drum 1 is arrested.
  • FIGURE 2 there is illustrated a pair of juxtapositioned figure drums or rollers, with the left-hand roller member being shown in section to reveal the mounting assembly therefor.
  • the figure drums 1 are each supported by the bracket means 8 attached to the base plate 11.
  • the bracket means 8 are provided with a bearing portion 12 which rotatably support a shaft member 9 which carries the figure drums 1,
  • the shaft member 9 supports at each of its ends a carrier plate or entrainment means 15 by means of which further roller units may be coupled thereto.
  • Such an arrangement readily permits the exchange or replacement of any of the figure drums 1 in a relatively simple and quick manner.
  • the bracket member 8 Secured to the bracket member 8 are the four photoelectric cells 3 and the lamp member 7, while for the sake of clarity in illustration the details of the mode of fastening have not been shown. Moreover, the rays of light from the lamp member 7a may pass directly through the slots 2a onto the photoelectric cells 3, or else may be reflected with the aid of suitable mirror means as is known to the art.
  • the arrangement of the read-out system is such that the lamp 7 supported by the bracket member 8 serves to illuminate the roller member 1 appearing at the right-hand portion of FIGURE 2, whereas the lamp 7a for the left-hand roller 1 of said figure may be carried by a similar bracket member not shown, or else in any other suitable manner.
  • the individual figure drums 1 are continuously driven by a suitable motor known to the art through the intermediary of the shaft means 9 and the slip coupling means 10.
  • FIGURE 3 substantially corresponds to that illustrated in FIGURES 1 and 2, with like r'e'ference numerals genera-11y denoting similar elements.
  • the primary difference between the embodiment of FIGURE 3 from the preceding discussed embodiment resides in the feature that the lamps 7 and 7a are replaced by the permanent magnets 13 and 13a, which by means of the cutouts or slits 2a appearing in the ma gnetizabl'e template or plate portion 16a of the figure drum 16 are adapted to actuate the vacuum-magnetic switches 14.
  • the magnets 13a and 13 are thereby poled such that one pole, for example the north pole, is arranged rat the top of the plane of the paper and the other pole at the bottom thereof.
  • FIGURE 5 The operation of this system thus corresponds to an arrangement of four adjacently arranged magnets, with each magnet being associated with one of the four vacuum switches 14.
  • FIGURE 5 Such an arr-angement is shown in FIGURE 5 wherein it will be understood that for each individual grouping there is provided a maximum of four permanent magnets 101 secured to the template portion 16a of figure drum 16 and cooperating with the stationary magnetic actuated switches 14.
  • the arrangement of FIGURE 5 substantially corresponds to that of FIGURE 3, for which reason like reference characters are again employed.
  • FIGURE 3 again it will be seen that the slits 2a of the plate or template 16a permit the magnetic lines of force to pass to the magnetic switches 14 to cause actuation of the braking means 4, much in the manner as previously described during the explanation of the embodiment shown in FIGURES 1 and 2.
  • FIGURE 4 there is illustrated a further embodiment of a read-out figure drum 1, substantially similar to the embodiments of FIGURES l and 2, with like reference numerals :again denoting similar elements.
  • the template 1 is provided with switch actuating means in the form of cam members, here illustrated as [four individual cam plates 20, 21, 22, 23 each of which is adapted to actuate an associated switch member 24, 25, 26 and 27 respectively.
  • the switch members 24 and 26 are arranged offset to the switch members 25 and 27, with each pair of switch members 24, 26 and 25, 27 being mounted to the bracket means 8 by a support member 28, only one of which is 7 shown,
  • the individual cam plates 20, 21, 22 and 23 are each provided with a cam control surface 29 which is so designed that for a given angular rotation of the cam plates 20, 21, 22, 23 a predetermined group of the switches 24, 25, 26 and 27 are actuated.
  • the arrangement of the cam plates 20, 21, 22, 23 with specially designed control surfaces is able to perfiorm a selective switch actuating function, in a manner substantially similar to the selectively arranged groupings of slots of FIGURES 1 to 3. It will of course be apparent to those skilled in the art that in place of four cam plates 20, 21, 22, 23 it is equally possible to provide a single cam member provided with four control surfaces, whereby the operation is identical to that aforedescnibed.
  • the figure drum of the present invention is readily capable of providing for a positive and reliable read-out of infiormation, and is relatively simplified in construction and operation in that only a single brake member is required for each figure drum.
  • the switch actuating means of the template may conveniently be designed as selectively arranged groupings of slots or cam members.
