Definitions

  • This invention relates to punching machines, and particularly to machines for'punching holes in tapes according to various codes.
  • the present machine was designed primarily for use in large institutions, such, for example, as department stores, wherein each sales girl, or group of sales girls, may employ one of these punches to record itemized sales, etc., upon a roll of tape, so that at the ends of given periods these tapes may be collected, and run through a machine which will interpret the punchings on the tapes, and transfer the data to statistical cards. Thereafter the cards may be used with standard tabulating equipment.
  • One object of the present invention is the recording of data upon a tape by means of a simple punching mechanism.
  • Another object is the punching of special holes in a tape, which holes may be employedto feed and guide it.
  • Fig. 2 is a rear elevation of the machine
  • Fig. 3 is a sectional elevational view taken substantially along the line 3-3 of Fig. 2;
  • Fig. 4 is a plan view of the punch mechanism
  • Fig. 5 shows a portion of the perforatedtape.
  • right-hand and left-hand etc. refer, respectively, to the right and left hands of an operator facing the front of the machine.
  • the framing of the ma chine consists generally of two upright brackets or main frames I and 2 screwed or otherwise secured toa base plate 3, which, in turn, is fastened to a larger base 4.
  • a pair of adjustable uprights 5 slotted with keyhole slots at 6 and l to accommodate between them a formed pin 8, upon which may be mounted a roll of blank tape 9.
  • the punch section of the present device is in many respects similar to that shown and described in the Patent -No. 1,086,397, issued to James Powers on February 10, 1914. Unlikethe punch mechanism disclosed in the Powers patent,
  • the present mechanism is designed particularly for punching coded perforations in a tape, rather than for punching them directly in a statistical card.
  • the machine is equipped with a top cover plate II which has generally the shape of an inverted U, and is fastened by screws to the main frames l and 2.
  • the plate H is recessed in three places, namely, at l2, l3, and M (Fig. 4).
  • 2 is to permitprojectionsof thesetting-slide detents to pro- .trude so that the operator may manually retract any setting slide at will.
  • the recess I 3 constitutes an opening beneath which may be seen thefaces of thesetting slides, each of which faces is numbered from 0-9, inclusive. It is through this opening that the operator inserts a stylus in notches in the various setting slides and pulls them down difierentially to set positions.
  • the recess I4 is merely a sight opening for disclosing to the operator in a convenient fashion the amounts which have been set up on the slides.
  • Lying directly beneath the cover plate II is a plurality of manuallyoperable setting slides I5 .(Fig. 3), each of which has riveted or otherwise suitably secured thereto, at right angles, to its top,
  • Strips l6 are equipped with small notches IBA (one for'eachnumeral) into which notches the operator inserts a stylus. She then pulls the stylus down until it limits on the bottom of the opening I3, which positions the same numeral under the sight opening l4, as can be seen at the very bottom of the opening l3.
  • IBA one for'eachnumeral
  • 5 are movable differentially in this manner, so that they may be set to show any numeral from to 9.
  • Each setting slide I is supported and guided by a comb bar I1 and a comb bar l8. These comb bars extend from side to side of the machine and are fastened to the main frames and 2.
  • are made fast in the control slides 22 so that any movement, forward or rearward in the machine, of the setting slides l5 will cause a corresponding movement in the same direction of the control slides 22.
  • each control slide 22 is formed with a plurality of lugs 24 thereon, which lugs force the punches through the tape during punching operations.
  • lugs 24 can be made of various widths and can be variously spaced according to the particular code it is desired to use. In the present instance a two-hole combinational code is employed.
  • Control slides 22 are mounted for forward and rearward sliding movement in a frame which consists of a lower plate 25, front and rear support bars 26 and 21, front and rear guide combs 28 and 29 fastened respectively to bars 26 and 21, an upper retaining bar 30 which serves not only to hold the control slides in the punch frame, but also as a limit stop for the rearward motion of these slides, and a pair of end plates 23.
  • the entire punch frame is supported at each side of the machine upon a U-shaped link 32 (see also Figs. 1 and 2) each link being pivotally connected at 33 to forwardly extending rock arm 34 mounted on a rock shaft 35, which, as can best be seen in Fig. 2, is journaled in the side frames and 2.
  • a die plate 45 Directly beneath the plate 39 is mounted a die plate 45, upon which the tape 9 rests.
  • This plate 45 is fastened to over-turned portions of brackets 46, which brackets are fastened upon the main frames and 2.
  • a removable box 41 is provided for the purpose of catching the punchings.
  • the normal position of control slides 22 is that shown in Fig. 3, wherein the foremost lug 24 is positioned over the rearmost or zero punch 36.
  • One step of movement forward of any of the control slides 22 is equivalent to the distance between the center lines of any two punches 36.
  • is formed with a depending arm 54 to which is anchored one end of a spring 55, the opposite end of which is anchored in the associated connecting piece I9.
  • Each spring 55 serves a twofold purpose in the present machine, viz., to urge its associated slides l5 and 22 toward their normal or rearward positions and to urge the toe 52 of an associated detent 5
  • is also provided with a pair of upright finger pieces 56 which, as was previously mentioned, extend through the opening
  • the operator should the operator incorrectly set a slide l5, she need only press the finger piece 56 to disengage the detent from the slide and permit the spring 55 to return it to normal.
  • are withdrawn from their associated slides I5, as soon as punching itself has taken place, by an automatic retract mechanism, which will later be described.
  • the present machine is driven by a manually operated crank 60, which, as can best be seen in Figs. 1 and 2, is fast upon the right-hand end of a main rock shaft 6
  • the crank 60 is pulled toward the front of the machine and returned to effect a punching and tape feeding operation. It is to be understood, however, that the machine can just as well be motor driven.
  • is journaled in the ear 66 and in the frames l and 2, and is held against lateral movement by suitable collars as shown.
  • are the driving devices for four separate mechanisms, namely, the automatic retract mechanism, the punch lowering and raising mechanism, the full stroke mechanism, and the tape feeding mechanism. These mechanisms will now be described in detail, beginning with the mechanism for raising and lowering the punches.
  • a two piece box cam 10 in which there rides a roller 1
  • an arm 34 also fast upon this shaft 35, is connected to each of the U- shaped links 32, which, in turn, are connected to the frame which carries the punches 36.
  • box cam 10 is moved degrees, and, as a result, the roller 1 is forced first up and then down and this in turn results in lowering and raising the arms 34 and links 32 to force the punches 36 through the tape 9 and then up to normal posiof the machine into a lug ZIZ (Fig. 3).
  • Figs. 2 and 3 the'outer portion of the box cam I is fastened to and spaced from a four toothed ratchet wheel 200 by studs 28L
  • the inner portion of the box cam "III is fastened "to'one face of the enlarged portion 293 of a shouldered hub 282 (see Fig. 2).
