Definitions

  • the present invention relates to means for multiplying the effective force of a fluid under pressure which is applied to a piston like member, and more particularly, to a new and improved card punching device.
  • Card punches of the prior art which have had wide application are operated with solenoids, with the punches being staggered in a circle on lever arms. While this punch means is fairly reliable, it also entails the use of several parts linked so as to produce a mechanical advantage in order to achieve an effective punching force. Such mechanical linkage is subjected to wear and tear of its component parts due to bearing friction, force moments, etc.
  • the present invention obviates certain of the above disadvantages of the mechanical linkage by providing a direct acting punch powered with a iluid under pressure, such as air or the like. Only one moving part need be provided which is the punch piston itself.
  • the punch of the present invention is therefore particularly adapted for use in the rapidly expanding fluid data processing art, wherein information is transmitted and processed via a iluid medium.
  • the manner in which the present invention accomplishes the above described function is to fabricate a punch piston having a plurality of circumferential grooves axially spaced along its length so as to form a plurality of surfaces which are essentially normal to the direction of the dynamic force applied by the actuating fluid pressure.
  • the punch is loosely iitted within a cylindrical Vhousing such that there is suicient clearance between the outside punch diameter and the inside housing diameter to allow the iluid to pass therebetween and exert its force on each of the multiple ring surfaces formed by the grooves in the piston body.
  • Yet another object of the present invention is to therefore provide a direct acting punch powered with a fluid, said fluid also being used for retracting the punch from the card subsequent to the punch stroke.
  • the principle of the present invention is particularly adapted for use as a card punch and has therefore been specifically shown in this environment, the scope of this invention is broader in that the principles here expounded can be utilized where there is desired the effective multiplication of force exerted by a pressure fluid.
  • the grooved piston may be used to drive a crank shaft by means 0f a connecting rod. Therefore, another object of the present invention is to generally provide a cylinder and loose tting piston arrangement wherein effective multiplication of the force in a low pressure fluid is accomplished by means of grooving in the piston body.
  • FIGURE l is a diagrammatic plan View of the invention as embodied in a card punch environment, which shows the punch and cylinder as well as the actuating and retracting mechanism;
  • FIGURE 2 is a detailed sectional view of the punch cylinder and piston
  • FIGURE 3 is a perspective View of the punch piston which emphasizes the arrangement of its circumferential grooves
  • FIGURE 4 illustrates an alternative embodiment of the retracting mechanism
  • FIGURE 5 shows a third embodiment of the retracting mechanism.
  • FIGURE 1 is a diagrammatic view of the invention when used in a card punch environment.
  • a punch chamber or cylinder 10 is provided within which is loosely iitted a punch piston 11 having one end 12 brought to a point for easy passage through a record card 13.
  • punch piston 11 When punch piston 11 is directed upwards against card 13, point 12 pierces said card and enters the opening 14 in die block 15.
  • the actuating Huid under pressure enters cylinder 10 via a port 16 and is applied against the face of end surface 17 of the punch piston, as well as leaking through the clearance formed between the outside piston diameter and the inside cylinder diameter t0 impinge upon a plurality of circumferential grooves not shown in FIGURE 1.
  • the drive or punch stroke of piston 11 is in the upward direction against the force of gravity.
  • the fluid entering port 16 is terminated and an auxiliary fluid stream is forced into chamber lil via a passageway 18.
  • the force of this fluid impinges upon piston 11 in the downward direction so as to disengage point 12 from record card 13 and thereafter cause piston 11 to return to the bottom of cylinder 10 adjacent port 16.
  • the force of the fluid from passageway 1S need not be large, inasmuch as it is aided by the force of gravity working against piston 11.
  • means are provided to move record card 13 subsequent to a retraction stroke so as to present an unpunctured surface vto the punch position.
  • the hole placed into record card 13 by punch 11 may be interpreted in a Variety of ways, depending upon the particular code utilized in the data processing system. Alternatively, the present invention may be utilized in systems other than those processing information wherever it is desired to punch a web of material.
  • the actuating fluid entering port 16 may be applied via a duct 19 from one output of a typical pure -iiuid amplifier 2i).
  • Amplifier 2@ normally comprises a solid body having a plurality of fluid passageways through which the working fluid may iow. This working fluid may be either air or another gas, or water or another liquid. Although these fluid passageways are shown invisible in the figure, it is to be understood that it is customary to mold or otherwise form the liuid passageways in one plastic laminate which is then covered on each side with solid plastic sheets so that the passageways are enclosed.
  • a compressor or pump not shown in FIGURE 1, supplies a suitable regulated stream of fluid to the power input passageway 2l via a duct 22.
  • the power stream passes through a restrictive orifice 23 and emerges into chamber 24 as a high velocity jet stream.
  • Chamber' 24 is formed by the convergence of left output passageway 25 and right output passageway 26.
  • the left wall 27 and the right wall 28 of the chamber are set back from orifice 23 and, in accordance with Bernoullis Principle, the high velocity jet issuing from orifice 23 creates regions of low pressure adjacent to these walls. Within these regions of low pressure are layers of fluid which move at a much slower speed than the jet stream, hence these regions are referred to as boundary layers.
  • these low pressure areas may be utilized to control the flow path of the jet issuing from the orifice 23.
  • Passage 29 may be selectively provided with fluid via a duct 3l, with said fluid issuing from passage 29 into chamber 24 via an orifice 32 positioned vin wall 27.
  • Passage 39 may be likewise selectively supplied with fluid via duct 33, with this passage entering chamber 24 via an orifice 34 in wall 2S. Both control streams are normally comprised of the same fluid as that found in the power stream within passage 21.
  • a control stream is initiated from orifice 34 which breaks or disperses a boundary layer and creates a condition of instability which tends to push the power stream Iinto a direction away from wall 28.
  • the power stream is thus pushed to the left, it withdraws more and more molecules of fluid from the region adjacent wall 27, thus creating a low pressure region.
  • the power stream thereupon moves into this low pressure region and locks onto wall 27, with the result being that the power stream now passes through passageway 25 to the duct 19 and into chamber l@ via port 16.
  • piston 11 begins to move upwards so that it eventually strikes record card L13 and punctures same.
  • control stream lfrom orifice 34 is discontinued and the control stream from himself 32 commenced.
  • This control stream from orifice 32 thereupon shifts the power stream within amplifier 20 so that it now exits from a second output thereof into the duct 35 which returns the fluid to the input of the pump.
  • a smaller duct 36 may be tapped from duct 35 so as to provide a resetting :liuid stream to passageway i8 for causing the retraction of punch piston 11 in the manner heretofore described.
  • FIG. 2 is a sectional View of the punch cylinder and piston which clearly shows the novel configuration of the piston and the loose fit between it and the cylinder.
  • Piston 11 is preferably sharpened at one end 12 to enable its passage through record card 13.
  • the diameter of the peripheral surface of piston 11 is less than the inner diameter of cylinder 19, so that there .is a clearance therebetween which allows the input fluid to leak along the longitudinal axis of the piston in the manner shown by the dotted lines.
  • the greater portion of the piston peripheral surface has multiple grooves 37 through 44 which may be machined therein. Although eight such grooves have been shown axially disposed along the length of piston 1l in FlGURE 2, a lesser or ⁇ greater number may actually be provided.
  • Each groove is delimited by two parallel side walls, one of which is noted by the latter a.
  • This side wall of a groove is that which is normal to the path of the fluid leaking between the outside piston diameter and inside cylinder diameter, such that the force exerted on said side wall due to the kinetic energy of the leakage liuid is in a direction tending to force the piston into record card f3.
  • Fluid is admitted by port le into chamber iti having a relatively low pressure on the order of live to thirty-live p.s.i.g.
  • the punch piston were accurately fitted to the inside of cylinder l@ so as to prevent huid leakage therebetween, the amount of pressure required would be of considerable magnitude in order to create sufficient force at piston end surface ll7 to push through a conventional yrecord card.
  • due to the loose lit of piston l1 within cylinder 10 a portion of the fluid leaks between the piston peripheral surface and the cylinder inside diameter at a relatively high velocity ⁇ due to the small cross sectional area of this clearance portion.
  • a passageway 18 is provided in the wall of cylinder l) through which a fluid stream travels to impinge upon the punch piston in order to effect the retraction thereof subsequent to the punch stroke.
  • passageway i8 enters the chamber at an angle so lthat the fluid Vstream exerts a downward force on the punch piston opposite to the direction taken by the piston during its punch stroke. If the punch 11 is placed below record card 13, as is the case in the preferred embodiment of the invention, then the force exerted by the retracting tluid stream from passageway 18 need only be great enough to overcome the friction of the record card upon end 12 of the piston so as to disengage same from the card.
  • punch cylinder may be lplaced on top of the record card if desired, with due changes being made in the force of the retracting stream.
  • FIGURE 4 is an alternative embodiment of the retracting means wherein passageway 18 is no longer provided in the wall of cylinder 10. Instead, the opening 14 in die block is elongated into a passageway at the opposite end of which is provided a fluid input via duct 36 fromV the appropriate output of the fluid amplifier shown in FIGURE l. If the scheme of FIGURE 4 is utilized, then the retracting lluid stream cannot impinge upon the punch piston until point 12 punctures the record card and exposes itself to the retractive lluid stream which enters passageway 14 in the die block.
  • FIGURE 4 an alternative mode of operation of FIGURE 4 is as follows: A source of fluid may be applied to passageway 14 which is main tained even during the punch stroke. As long as there is no perforation in record card 13, then this lluid in passageway 14 cannot effect the motion of the punch piston in cylinder 10. However, as soon as the sharpened punch point 12 passes through the record card and enters passageway 14, it is immediately exposed to the lluid pressure therein which thereupon forces the piston to return to its original retracted position.
  • record card 13 Upon termination of the fluid entering port 16, record card 13 is then moved so as to remove the newly punched hole from alignment with passage 14 and cylinder 10. The effect of the retracting lluid in passageway 14 is thereby blocked by an unpunched portion of record card 13. Continual lluid llow at conduit 36 causes faster retraction of the punch than if flow at conduit 36 were initiated only after termination of llow at port 16.
  • FIGURE 5 shows still another embodiment of fluid retracting mechanism which may be used in conjunction with the present invention.
  • Retraction of piston 11 is here caused by the creation of a suction force in the end of the cylinder opposite that adjacent record card 13. This force is created by a stream of fluid entering this cylinder end via an input conduit 40 and exiting through a conduit 41 in the direction of the arrows.
  • a conventional ball and check valvel 42 Inserted within conduit 4i) is a conventional ball and check valvel 42 which serves to prevent fluid flow in the conduit in a direction opposite to that indicated by the arrow.
  • a guided ball check valve comprised of a ball 43 positioned in a guide or race way 44 so that said ball is movable to block either port 16 or port 45, the latter providing the outlet from the cylinder to conduit 41.
  • ball 43 is moved to block port 45 and so prevent exit of said power stream therefrom.
  • the ball and check valve 42 in conduit 4@ likewise prevents any portion of the power stream from escaping from cylinder through port 46.
  • the power stream is applied against piston 11 and drives same through the record card in the manner previously described.
  • Fluid llow in conduit 42 may also be used to maintain piston 11 in its retracted position in the event that the punch cylinder 10 is not vertically arranged to utilize the force of gravity for this function.
  • the arrangement shown in FIGURE 5 may be used in combination with the arrangements in FIGURES 2 or 4.
  • fluid in conduit 36 of FIGURE 2 might be used to effect the retraction of the punch, and fluid through conduit 42 might thereafter be used to maintain and hold the punch in its retracted position. Therefore, depending upon the particular environment in which the invention nds itself, the retracting mechanisms shown in FIGURES 2, 4, and 5 may either be used singly or in combination with one another.
  • the loose fitting multiple groove piston may be employed to perform work other than that of punching holes in web like material.
  • the punch cylinder may be placed above the record card instead of below, so that the force of gravity upon the punch piston is used to assist the actuating tluid pressure during the punch stroke.
  • the retracting fluid stream must have a somewhat greater force in order to raise the punch piston and maintain same in its retracting position.
  • Horizontal arrangements of cylinder 10 may be utilized. It is there# fore apparent that many modifications and alterations may be made by one skilled in the art without departing from the spirit of the invention as defined in the appended claims.
