Definitions

  • the invention relates to perforating apparatus in a dictating machine environment in which all of the primary working elements of the apparatus are positioned adjacent an index slip being perforated on a side opposite to that being observed so that entire index slip is visible.
  • the dictating machine is controlled by a microphone handset having an index control button. Movement of the button to the alternative Letter (LTR) or Secretary (SEC) positions operates mechanisms to punch corresponding perforations in an index slip 21.
  • the perforations are effected by a punch element that is mounted in a stripper for reciprocation from a home position toward the front of the machine and then back to the home position. A conical portion of the punch element tears the index slip during the outward movement from home position and severs a chad in the slip as it returns to the home position.
  • the perforating apparatus is disclosed herein in connection with dictating equipment but should find usefulness in a wide variety of equipment in which perforation of a media is required.
  • Dictating machines of many different types are in widespread use today. Their advantages, including rapid and efficient preparation of reports, letters, and similar documents using various types of recording media such as magnetic belts or sheets, are well known. Such machines are normally provided with a transducer, such as a microphone having control buttons thereon for controlling various machine operations, and circuitry and mechanisms for translating the dictators speech into signals that may then be recorded on the recording media employed.
  • a transducer such as a microphone having control buttons thereon for controlling various machine operations, and circuitry and mechanisms for translating the dictators speech into signals that may then be recorded on the recording media employed.
  • a typical dictating capacity for the belt is ten to fourteen minutes.
  • the drive mechanisms in the equipment serve to move the magnetic recording head from a zero position to the end of the belt. During this movement of the head the belt is rotated and the combined movements of the belt and head result in a helical path being recorded on the belt.
  • indexing means serves not only to inform the dictator of his position, but also to inform the transcriber at a later time of the length of the various dictated materials on the media as well as special instructions that should be observed during the transcribing procedure.
  • Indexing mechanisms in the past have taken a number of forms but in practically every case they include some sort of index slip that is arranged adjacent the record media and having index markings on it that correspond to the increments of dictating intervals on the recording media.
  • the index slip might have designations printed thereon from zero to ten at regular intervals corresponding to each minute on the recording media.
  • Many methods have been proposed in the past for marking the index slip in order indicate the ends of letters or special instructions. Index slips have been provided with specially treated surfaces that can be scraped off to give an indication.
  • One of the most common ways of making indications on the index slip is to perforate the slip by means of an associated perforating mechanism that moves along with the head and which is always positioned adjacent the index slip in a position that corresponds to the relative position of the head with respect to the recording media.
  • an object of the invention is to provide a simplified perforating apparatus.
  • Another object of the invention is to provide a perforating apparatus that is arranged in such a fashion that any media being perforated is visible at all times to an observer.
  • Another object of the invention is to provide a perforating apparatus that may be operated electrically or manually as requiredlby equipment parameters.
  • Another object of the invention is to provide an indexing mechanism for dictating equipment that performs the indexing operation with a high degree of reliability and which operates with complete visibility for the user of the equipment.
  • Another object of the invention is to provide a perforating apparatus which is designed in a manner to reduce noise of operation.
  • a further object of the invention is to provide apparatus for perforating closely spaced indicia with compactly arranged mechanisms.
  • Still another object of the invention is to provide apparatus for perforating a record media in a rapid and sh-arply defined fashion.
  • a perforating apparatus is arranged in such a manner that all of the primary working elements of the apparatus are positioned adjacent the record media being perforated on a side opposite to that being observed.
  • the mechanisms of the present invention are designed in such a manner that rapid and smooth operation is insured with perforations that are cleanly severed.
  • FIG. 1 is a diagrammatic perspective view of a dictating equipment in which the invention is incorporated.
  • FIG. 2 is a front elevation of a portion of the indexing mechanism in the dictating equipment of FIG. 1.
  • FIG. 3 is a top elevation of certain perforating mechanisms used in the equipment of FIG. 1.
  • FIGS. 4, 5, and 6 represent a typical sequence of operation of the perforating mechanisms illustrated in FIG. 3, slightly modified.
  • FIG. 7 illustrates an alternative arrangment of the perforating mechanisms previously shown.
  • FIG. 8 illustrates another embodiment of the perforating mechanisms and associated actuating elements.
  • FIG. 1 illustrates a 'well known dictating machine configuration
  • the dictating equipment is not shown in complete detail but generally is comparable to that dislosed in US. patent application Ser. No. 216,261, now US. Patent 3,222,460, entitled Multiple Station Selection System, with N. J. Albanes and M. P. Langendorf as inventors, filed Aug. 10, 1962, and assigned to the same assignee as the present application.
  • the dictating machine is designated 1 and is interconnected by a cable 2 to a handpiece microphone 3.
  • Machine 1 has various circuits and mechanisms for recording and reproducing dictated material and for giving an indication of the progress of dictation or transcription.
  • a belt release lever 4 is pulled forward to permit the loading of a magnetic belt 5, whereupon the belt release lever 4 is moved again to the position shown in FIG. 1.
  • Signals derived from the microphone 3 through a transducer area 6 are directed by cable 2 to amplifier block 7 and from there to the recording head 8.
  • Recording head 8 is mounted for lateral movement on a carriage 9 from a home position at the extreme left of belt to an advanced position at the extreme right of belt 5.
  • Belt 5 is rotated by mandrel 10 in a forward direction indicated by arrow 11 past recording head 8.
  • the relative movements of head 8 and belt 5 result in the recording of a helical path about the periphery of belt 5.
  • Machine 1 also has a speed control lever 12, a volume control knob shown in phantom at 13 and a tuning or tracking knob that is designated 15.
  • Lever 12 permits the slowing down or speeding up of the belt to suit the listeners requirements.
  • Knob 13 controls the volume level during playback.
  • Knob 15 enables the user to position head 8 with a fine degree of control in order to establish proper tracking of a recorded path.
  • microphone 3 has a mode control button 16 with three positions: Record (REC), Listen (LIS) and Review (REV).
  • Microphone 3 also has an instruction or indexing button 17 with three positions: Letter (LTR), off, and Secretary (SEC).
  • Microphone 3 also has a dictate bar 18.
  • mode control button 16 is moved to the upper Record position.
  • the mode control button 16 is moved to the central Listen position, whereupon the drive mechanism in machine 1 is automatically activated to rotate belt 5 and move head 8, and to thereby generate signals for reproduction by transducer 6. If the dictator desires to hear material that he has previously recorded he moves the mode control button 16 down to the lower position for Review purposes. Button 16 is spring loaded from the lower position to the central position.
  • buttons 16 are provided with an indexing assembly 19 and associated perforating mechanisms indicated at 20. Portions of these assemblies are illustrated with a front elevation in FIG. 2.
  • the indexing assembly has provision for retaining an index slip or tab 21 having numerical designations thereon 'which correspond to the relative location of the head 8 in relation to belt 5. In the example illustrated, index slip 21 has 4 fourteen increments respectively designated 0, 10 etc. through 140. These correspond to fourteen minutes of dictation capacity on belt 5.
  • index lever 22 Associated with carrier 9 is an index lever 22 having a serrated element 23. Sound head 8 can be positioned to any point with respect to belt 5 by squeezing element 23 and lever 22 together and thereafter sliding lever 22 to the right or left as desired. Certain portions of the indexing assembly 19 have been cut away in FIG. 1 to more clearly show the structural configuration of the perforating assembly 20.
  • Assembly 19 has a transparent material 24 with slots 25 and 26. Slots 25 and 26 are positioned in such a manner that when index slip 21 is properly inserted in the index assembly, two channels, a Letter instruction channel, and a Secretary instruction channel on the index slip will be completely exposed to view while the remainder of the index slip 21 can be seen through the transparent material 24.
  • Button 17 on microphone 3 has upper and lower positions that correspond respectively with the upper and lower channels on the index slip 21.
  • button 17 on microphone 3 is moved to the upper Letter position, a hole is perforated in the top channel of the index slip 21 by actuation of perforating mechanism 20.
  • knob 17 on microphone 3 is moved to the lower Secretary instruction position, a hole is perforated in index slip 21 in the lower channel by the perforating mechanism 20.
  • a perforation in the upper channel informs the transcriber that a letter has ended at the point of perforation.
  • the perforations in the two channels of index slip 21 are formed by actuation of punch elements 27 and 28 that are respectively associated with channels 25 and 26, and the operation is such that the index slip is completely visible at all times as head 8 scans belt 5 from beginning to end.
  • the punching operation takes place with the following mechanisms.
  • FIG. 3 is a top cross-sectional elevation of the perforating assembly and only punch element 27 is shown.
  • Punch element 27 is mounted in a stripper 30 for reciprocation from a home position toward the front of the machine and then back to the home position as shown in FIG. 3.
  • Punch element 27 is arranged for reciprocation in an opening 31 of stripper 30.
  • Punch element 27 has three major portions. A conical portion 27a is positioned toward the front of the machine.
  • a cylindrical portion of lesser diameter 27b is formed as an intermediate part of punch element 27, and a shank portion 270 is at the rear of punch element 27.
  • Punch element 27 also has a flanged surface 27d at the rearmost extremity.
  • Punch element 28 is formed like punch element 27.
  • Punch element 27 is normally maintained to the rear in its restv position by a compression spring 32 while punch element 28 is normally maintained in its home position to th rear by a compression spring 33.
  • actuator bail member 34 positioned ad jacent the rearmost extremities of punch elements 27 and 28 is an actuator bail member 34 that is rotatably mounted in a bushing 35 at one end and in a bushing 36 at the other end.
  • Actuator bail 34 has an upper flat extension 37 that lies adjacent the rear extremity of punch element 27 and a lower flat extension 38 that is positioned adjacent the rear extremity of punch element 28;
  • Actuator bail 34 is mounted for movement under control of a punch plate 39 that in turn is controlled by plungers 40 and 41. Plungers 40 and 41 are moved by upper and lower solenoids 42 and 43. Bail 34 is also suming that it is desired to perforate a Letter instruction hole in index slip 21, button 17 is moved to the upper Letter (LTR) position. Movement of the button 17 in this direction results in the energization of solenoid 43. Plunger 41 is thereupon pulled to the rear which rocks plate 39 in a counterclockwise direction as viewed in FIG. 1. Rocking of plate 39 results in the associated actuator bail 34 also rocking with top flange 37'being moved toward punch element 27. This causes punch element 27 to move forward in the opening 31 with continued movement causing conical portion 27a of punch element 27 to pierce the index slip 21.
  • FIGS. The sequence of operation is shown in FIGS. Referring to FIG. 4, punch element 27 and bail 34 are in the home position. When operated, bail 34 moves in a direction toward the front of the machine as indicated by arrow 44, FIG. 4. The piercing of index slip 21 by punch element 27 is illustrated in FIG. 5. The movement of punch element 27 is quite rapid and a perforation occurs when conical portion 27a passes through slip 21 due to the inertia of slip 21 and the relative positioning of slip 21 adjacent the transparent material 24.
  • FIG. 6 illustrates conditions as punch element 27 is restored to its home position.
  • the stripper is shown with a slanted front face that is slightly modified from FIGS. 1-3, and is redesignated 30w.
  • Conical portion 27a has a relatively flat rear surface that cooperates with the slanted face of stripper 30a.
  • punch element 27 passes through slip 21 and prior to its complete return to the home position, the severed portions of slip 21 drop into the area of portion 27b of punch element 27. These portions are carried by the conical portion 27a to the rear as the punch element restores.
  • a shearing action takes place due to the fact that the fiat surface of portion 27a is fitted with rather close tolerance inside the opening 31a and also due to some extent to the slanted face of stripper 30a.
  • the front face of stripper 30 can also be changed so that it is more or less vertical in relation to the index slip. This is illustrated in FIG. 7 where a transparent plate 45 is positioned in front of an index slip 46. A punch element 47 is positioned inside a stripper element 48 which has a substantially vertical front surface 48a. Operation of the perforating mechanism of FIG. 7 would occur in approximately the same fashion as with the mechanisms previously discussed except that the shearing action on the return movement of the punch element 47 will take place about the same time around the entire edge of the opening 49 in stripper 48 rather than in a scissors-like manner as occurs with the slanted surface of the stripper 30a.
  • a chad drop such as opening 59 in FIG. 7, can be provided to allow chad to drop out of the mechanism immediately following each perforation.
  • the perforating mechanism of the present invention could be actuated manually rather than electrically as previously described.
  • the dashed bail 34 would then not be provided at all.
  • a manual depression of the punch element 27 by pressing on flange 27d in the same direction as indicated by arrow 44 would result in a comparable perforating action.
  • Additional linkages could be added to the mechanism to provide manual levers that would be more accessible to the front of the device.
  • a manually actuated perforating element of this type could be advantageous in a small portable dictating machine, for example.

  • Punch element 53 has an associated solenoid 54 while punch element 55 has an associated solenoid 56 that is positioned to the rear and below solenoid 54.
  • Punch element 53 extends through solenoid 54 in a coaxial fashion to terminate with a flange portion 53a while punch element 55 extends through solenoid 56 and terminates with a flange portion 55a.
  • Punch elements 53 and 55 are maintained in a normal rearward home position by respectively associated spring elements 57 and 58.
