- Another specific object of the present invention is to provide a machine of this character in which a single switch is used to effect energization of the machine and to effect a de-energization of the machine automatically after a predetermined angular rotation of a shaft.
- Anotherspecific object of the present invention is to provide an arrangement of this character capable of cutting extremely thin film non-metallic materials which have very high tear strength such as for example Mylar which has a tendency to deform or stretch rather than to shear evenly.
- Another specific object of the present invention is to provide a cutting arrangement which is essentially selfsharpening.
- Another specific object of the present invention is to provide an arrangement of this character into which one or more cards may be inserted so that the operating speed advantages of multiple card aperturing during a single operating cycle may be realized.
- Another specific object of the present invention is to provide a machine of this character in which there is no rigid mechanical connection between the cutting element, the driving mechanism and energy source such that neither the cutting element, mechanism nor driving motor can be damaged by an inadvertent overloading of the punch member.
- Another specific object of the present invention is to provide an arrangement of this character involving an energy storage system wherein rapid linear reciprocationis accomplished in a small fraction of the total operating cycle, the larger fraction of the remainder of the cycle being used for the restoring of energy.

- This plate 30 as seen in FIG. 2 has an upper rounded edge portion 36 to facilitate the introduction of a card and a shouldered portion 38 acting as a stop for the introduced card and also as a partial support for the card.
- a card supporting structure that includes a horizontally extending bar 40 with an upper tapered lip portion 41 and a plate 43 having a right angle bent portion 44 secured to the frame side plate 11 by screws 46, the bar 40 being secured to this plate 43 by screws 47; and as a prolongation of the plate shouldered portion 38 the frame side plate 11 has an open ended slotted portion 49 allowing introduction of the card so that the bottom edge of the card may rest on such shouldered portion 38 and the card ledge or bar 40 with a portion of the card leaning against plate 43 and contacting the stop element 42 so that the card is indexed with respect to the stationary cutting element 34, the stop element 42 being secured to the frame plate 15 by screws 42A as shown in FIG. 6.
- Cutting or punching of the card occurs between the hardened stationary rectangular insert 34 and a rectilinearly movable punch or cutter assembly 50 which is moved by lever 52 having its upper end pin connected to assembly 50 and its lower end pivotally mounted in bearing assembly 54 mounted on base frame plate 10, the lever 52 being actuated at a point intermediate its ends by a mechanism described later.
- the cutter assembly 50 as seen in FIG. 13 includes four cutting elements 55, 56, 57 and 58 secured in interlocking relationship by screws 60 to a plate 62 which, in turn, is secured by screws 63 to the front face of the support block 64 with the rearwardly located straight edges of the cutting elements bearing on a peripheral recessed portion of plate 62 as illustrated in FIG. 6 and with the forwardly located cutting edges of the cutting elements being inclined with respect to the plane of such plate 62 such that adjacent ends of adjacent cutting edges are separated different distances from such plane, the smaller end of one cutting element being adjacent to the larger end of the adjacent cutting element whereby each cutting element acts as a scissors element with respect to a corresponding edge of the hardened insert plate 34 (FIG. 2).
- the support block 64 has a slotted portion 66 for accommodating the end of lever 52 and a hole 67 extending therethrough for receiving a pivot pin 69 (FIG. 2) engaged by an open ended slotted portion 71 in'lever 52. Also as seen in FIG. 13 the support 64 has a longitudinally extending bevelled surface 70.
- the cutter assembly 50 also includes an air nozzle 62A threaded in plate 62, the nozzle 62A being in communication with an angled passageway 628 (FIG. 6) having a fitting 62C threaded therein for attachment to one end of a flexible hose 62C having its other end connected to the outlet side of an air pump 62D (FIG. 1) which is operated after a cutting operation to produce a blast of air from nozzle 62A to clear the machine of that rectangular portion cut out of the cover sheet.
- an air pump 62D FIG. 1
- This cutter assembly 50 is slidably mounted using the previously mentioned bevelled surface 70 on cutter block 64 as a bearing surface and against which pressure, developed by springs, is applied to urge the assembly 50 against the raised bearing surfaces 73 and 74 (FIG. respectively, on replaceable bearing blocks 81and 83 mounted on corresponding interior sides 75 and 76 of L-shaped bearing block 77 integrally formed with a plate portion 78 for mounting on the apertured frame plate by screws 79.
- This bevelled surface 70 on cutter assembly 50 is engaged by a bearing plate 80 (FIG. 9) slidably recessed within an apertured portion 82 in the bearing support 84 and urged outwardly by coil compression springs 86, the bearing support 84 being secured to the apertured frame plate 15 by screws 88.
- the open ended aperture portion 82 may be filled with a lubricant or the plate 80 may be of self-lubricating composition.
- the cutter assembly 50 mounts a spring urged card engaging frame 90 (FIG. 14) using the following construction.
- a supporting frame 92 (FIG. 15) is secured by screws 93 on the cutter plate 62 and a pair of screws 94 passing through the frame 92 and coil compression springs 96 is threaded in the card engaging frame 90 so I that such frame may slide on the outer surfaces of the cutting elements 55-58 during operation of the machine for resiliently clamping the card against the cutter plate 34 just prior to and during the cutting operatlon.
- the lever 52 is actuated to move the cutter assembly 50 using the following construction.
- an electric motor 101 having mounted thereon a speed reduction unit 102 with the output shaft 104 of this unit extending through frame plate 11, the motor-speed reduction assembly 101, 102 being secured to side plate 11 by bolts 106.
- the shaft 104 has secured thereto one end of a shaft 107 as a prolongation of the same, the shaft 107 extending through elongated aligned slotted portions 1 12, 1 13 in a rod 114 and having its other end journalled for rotation in the bearing assembly 109 mounted on frame plate 12; and three cams 110, 111 and 135 are secured on shaft 107 with the cam 111 being located within a longitudinally extending slotted portion 116 of rod 114 for engagement with the spring urged roller 118 which is also in such slotted portion 116 with ends of its shaft 119 being slidably mounted in the aligned rod slots 120 and 121.
- the roller 118 is pressed into engagement with cam 111 by a coil compression spring 123 around rod 114 and having one of its ends bearing against a washer 125 with a shouldered portion engaging the roller shaft 1 19, the other end of spring 119 bearing against a washer 127 which is adjustably supported by a nut 128 on rod 114 for adjusting the compression of spring 123.
- rod 114 is bifurcated. to straddle an intermediate portion of lever 52 and a pivot pin 136 secured to rod 114 provides a pivot for pivoted movement between rod 1 14 and lever 52.
- the pivot pin 136 also provides a pivot for an intermediate portion of a pump actuating arm 137 having its lower end cooperable with the movable pump actuating element or piston 62E and its upper end carrying an adjustable screw 142 therein for adjusting the spacing between such screw 143 and the stationary support bracket 23.
- cam 110 a cam with two diametrically disposed indented portions 138, 139 (FIG. 7) separated by two diametrically disposed circular lobe portions 140, 141 affects essentially the positioning of lever 52 and hence the positioning of the cutter assembly with respect to the stationary cutter element 34 whereas the angular position of the other cam 111 (FIG. 3) affects essentially the degree of compression of spring 123.
- the two cams 110, 111 each being keyed to the same shaft 107 rotate as a unit in the clockwise direction in FIGS. 2, 3, 7, 16 and 17.
- the cam 110 maintains the cutter assembly in its fully retracted position shown in FIG. 2 but that progressively more energy is stored in the spring 123.
- the driving motor is automatically de-energized by means described later so that at point B, a rest position, the spring 123 is fully stressed.
- the switch 200 is connected in series with the driving motor 101 and is operated in accordance with rotation of the cam on shaft 107, the cam 135 being shown in its normal, at rest, position where one of its two .lobes 135A engages the switch actuating element 200A to thereby maintain switch 200 in its open position.
- the switch 200 is mounted on a lever plate 202 which has an intermediate portion pivoted at pin 203 on support plate 11, has one of its end pins connected at 205 to one end of lever 207 and has the other one of its ends connected through overcenter snap spring 207 to a pin 209 on support plate 11.
- the lever 207 has an intermediate portion pivoted on pin 210 on support plate 11 and its other end connected to a transversely extending actuating bar 213 so that by depressing the bar 213 the lever plate 202 is pivoted in a counterclockwise direction in FIG. 4 to cause the spring 207 to snap overcenter to disengage the switch actuating element from cam lobe 135A and to allow the switch 200 to close and thus energize the driving motor causing the cam 135 to rotate in the clockwise direction in FIG. 4.
- lever 137 When the upper end of lever 137, more specifically the adjustable screw 142 thereon, engages the stationary bracket 23 the lever 137 pivots in a clockwise direction to cause its lower end to move in engagement with the air pump piston extension 62E to cause an air jet to be produced at nozzle 62A to blow away the rectangular cut out portion of the card cover sheet through the frame aperture 32.
- cams have long life considering particularly that only the circular portion of cam 110 is fully loaded and pressure on such cam is relieved when the roller 132 engages the indented portion 138 of the cam 110.
- peak power requirements are reduced so that the driving motor may be small and inexpensive, due to low output speed and torque requirements.
- the cutter may be manually operated using for example a manual operator connected to lever 52 in which case the rod 114 is disconnected from lever 52.
- the movable cutter assembly described is particularly useful in each case in progressively cutting that very thin material N which is bonded to that marginal edge portion defining the rectangular apertured portion of card C.
- double lobe cams are used only to allow the use of very low cost, standard motors.
- Single or triple lobe carns would provide identical cycling to the device.
- lever 52 could be rigidly connected to the punch, and operated in circular motion about a lower pivot point.
- the cutter assembly 350 now comprises a single generally rectangular block as seen in FIG. 21.
- Such assembly 350 is defined by four raised and pointed corner portions 350B, 350C, 350D and 350E.
- Each of such corner portions is actually the apex of a forwardly extending triangular portion of the block.
- the corner portion 350B is at the outer end of the line 350G (FIG. 21) which is the intersection of two face portions 350H, 350].
- the corner portion 350C is at the outer end of the line 350L which is the intersection of two face portions 350M, 350N; and the faces 350J, 350M intersect at a line 3501 which is depressed so that in crosssection as seen in FIGS. 20 and 21, the corner portions each extend forwardly as the apex of a solid right angle.
- the cutter assembly may be characterized as a rectangular block formed with solid triangular portions at each of its corners with the apex of each such triangular portions being in the same plane and extending foremost precisely at each corner.
- the line 350G representative also of the other three like lines extends diagonally inwardly and downwardly.
- the line 350P representative also of the other three like lines extends inwardly with all points on such line being substantially at the same elevation. This means that as the assembly 350 is advanced during the cutting operation each of the four corner portions are progressively moved in like measure through the card with cutting or shearing being accomplished progressively at the eight peripheral edge portions, two of which are referenced as 350R and 3508 in FIG. 20 and as will be seen extend towards each other in a downward or inward direction.
- a nozzle 362A (like nozzle 62A) but now a freely floating piston 401 is slidably mounted in the bore of such nozzle as shown in FIGS. 22 and 24.
- This piston 401 is provided with a series of external grooved portions 401A extending axially thereof to allow the compressed air supplied as before from the pump via hose 362C to escape from the forward end of nozzle 362A.
- the pressure of the air causes the piston 401 to move so that ultimately an end of the piston 401 projects through the forward end of nozzle 362A to contact the cut portion of the cover sheet to thereby further assure removal of the cut-out portion from the machine.
- the action of the air jet is now supplemented by a mechanical action resulting from movement of the piston 401.
- a subatmospheric pressure is developed in hose 362C causing the piston to move backwards to its retracted position from where it again may move with momentum for the above purposes during the succeeding cutting operation.
- the cutter assembly 350 is provided with two inwardly disposed raised portions defined by the round heads of rivet-like elements 406, 407 which may be accurately located to provide a'limited contact area with the cut-out portion to again further assure removal of the cut chip.
- the nozzle 362A is threaded in the cutter block 364 and the cutter assembly 350 is accurately located on block 364 using dowel pins M3.
- the cutter assembly 350 is otherwise maintained on cutter block 364 and in relationship to the spring urged card engaging frame 390 as previously described in the des'cription of frame 90 in the previous figures.
- a pair of rollers 380 rotatably supported on a corresponding pin or shaft 381K now engages the beveled surface 370 of cutter block 364 for generally the same purposes as the previously mentioned plate 80.
- a cutter assembly having a support; four cutting knives mounted on said support in a rectangular pattern and with respect to a common plane on said support with each knife having a cutting edge inclined with respect to said plane and with adjacent ends of adjacent knives extending unequal distances from said plane; an apertured plate slidably mounted on said support to a position extending forwardly of and surrounding said knives; and spring means acting between said plate and said support normally urging said plate to said position.
- a cutter assembly having a support; cutting means mounted on said support in a rectangular pattern and with respect to a common plane on said support with each of said cutting means having at least one cutting edge inclined with respect to said plane; an apertured plate slidably mounted on said support to a position extending forwardly of and surrounding said cutting means; and spring means acting between said plate and said support normally urging said plate to said position, said cutting means comprising cutting knives with each knife having a cutting edge inclined with respect to said plane and with adjacent ends of adjacent knives extending unequal distances from said plane.
