Application June 8, 1936, Serial No. 84,150

30 Claims.

This invention relates to a machine for punching perforations in cards such as address bearing stencils and printing plates employed in addressing machines.

In my copending applications Serial No. 69,803, filed March 20, 1936, and Serial No. 75,118, filed April 18, 1936, I have disclosed printing machines operating upon address bearing stencils and printing plates and arranged to mark on a record sheet at positions denoting different items of statistical information, the marking being controlled by and corresponding in positions to perforations selectively positioned on the stencil 'or printing plate. The stencil or printing plate is provided with a plurality of differently positioned zones each corresponding to a different item of statistical information and capable of receiving a perforation when a mark corresponding to the perforated zone and hence to the selected statistical item is intended to be recorded upon a record sheet.

An object of the present invention is the provision of a machine arrange-d to perforate the stencil or printing device in positions selected at the will of an operative usually under guidance of a prepared list containing statistical items pertinent to the addresses borne by the printing devices.

A further object of the invention is the provision of a machine adapted to advance a succession of cards into and out of a perforating position, and punching means selectively operable under control of an operative to form perforations at selected positions in the successive cards.

Another object of the invention is a stencil perforating machine adapted to operate upon 'a succession of printing devices having a plurality of differently positioned zones indicative of different items of statistical information, the machine having a series of independently operable punches each of which registers with a separate item zone of the stencil when the stencil is in perforating position, and means controlled by the operative to select the punches desired for operation on the printing devices.

Another object of the invention is the provision of a perforating machine having a series of punches operative upon a printing device disposed thereunder, a reciprocating member disposed above the punches and apunch-selecting rod capable of being positioned in engagement with a selected punch and between it and the reciprocating member to receive the thrust thereof and transmit the thrust tothe punchv A yet further object of the invention is the provision of a card perforating machine having a series of punches operable upon the card disposed therebeneath, a reciprocable punch operating member, and a free punch-selecting rod capable of being positioned manually between the reciprocating member and a. selected punch and in engagement with the latter and arranged to control an electric circuit effecting the reciprocation of the reciprocating member to carry out a punching operation upon the selected punch.

Another object of the invention is the provision of a card perforating machine having the electrical circuit as above described together with means controlled by apart of the mechanism for interrupting the circuit at a part of the operating cycle thereof that insures but a single punching operation of the machine on a selected punch.

A yet further object of the invention is the provision of a card perforating machine having a reciprocable punch operating member and manually controlled means for bringing a punch, through the operation of said member, into engagement with any one of several differently positioned perforation receiving zones of the card.

A yetfurther object is generally to improve the construction and operation of card punching machines.

A card perforating machine having the punch operating mechanism of the present machine but different punching and perforation location selecting means is disclosed in a concurrently filed application of Ptofi Elliott Serial No. 84,149.

Fig. 9 is a sectional view of the machine controlled switch.

Fig. 10 is a section taken along line llll0 of Fig. 2.

Fig. 11 is a plan view of a stencil or printing plate perforated by the present machine.

As illustrated in Fig. 11 the card or printing device comprises a stencil it having a stencil sheet E8 in one portion bearing an address 28. The stencil in another portion thereof has a series of zones 22, the different positions of which denote different statistical items. The zones 22 are arranged in horizontal and vertical columns and are consecutively numbered as at 24.

The stencil herein shown has provision for sixty zones, although the precise number is of no particular importance to the present invention. Each zone is preferably provided with a mark, as a small circle 26 printed thereon for indicating the location of a possible perforation. With the perforating mechanism incorporating the present invent-ion such marks 26 are not necessary. They are desirable, however, in indicating the location of a perforation that may be formed by hand.

The stencil is adapted to receive perforations 28 in selected zones. The perforations control the passage of marking members through the stencil and into pressure applying relation with a record sheet thereunder for the purpose of making a mark on the record sheet in a location corresponding to the location of a perforation, thereby to indicate by its position on the record sheet the item of information denoted by the perforated zone of the stencil.

The machine for perforating the stencil comprises a table as, see Figs. 1, 2, and 3, supported on uprights 32 and having its operative parts operated by a power device 34, now common in the art. The power device includes a continuously rotating shaft 36 and an intermittently rotating shaft 38, the latter shaft being arranged to make one complete revolution per operation and then to stop. The rotation is under control of a pedal 46, which when depressed and subsequently released effects one complete rotation of the shaft 38.

A collection of the stencils it preferably with the addresses 2E3 thereon is contained in a holder 42 disposed at one end. of the table 30 and in register with the entrance of a stencil track formed by a pair of horizontally spaced guide rails 44 which are spaced above the table. The lowermost stencils of the holder are advanced in successive order into and along the track by a reciprocating pusher 46. Said pusher is reciprocated by a vertical lever 48 pivoted to the frame of the machine at 59 and connected to the pusher by a link 52. The lever is reciprocated by means including an eccentric 54 which is fixed to and is rotatable with the shaft 38. The eccentric has an eccentric strap 56 that is swiveled to the end of a pivoted arm 58 that reciprocates a lever 68 hearing against the lever 48 and connected thereto through a tension spring 62. The arrangement of the arm 58, lever 50 and spring [52 is such as to permit reciprocation of the parts as a unit under ordinary conditions but to permit the lever to stop reciprocation if a stencil or printing device should jam in the track 4-4. The perforated stencils are discharged from the end of the track into a stencil receiver 64.

The successive stencils rest stationary in the middle portion of the track where they are operated upon by the punching or perforating mechanism. Said mechanism includes a bracket 65 fixed to and upstanding above the table 3! alongside and in the rear of the Stencil t a k. Said bracket is provided with a pair of parallel bosses 58 in which a pair of vertical rods it are reciprocable. A punch operating member '52 in the form of a flat plate which projects forwardly of the machine over the perforation receiving zone of the stencil is fixed to the upper ends of the rods in by means including nuts M. As herein shown the plate 72 is electrically insulated from the rod ill by means of insulating bushings and washers 716.

The lower ends of the rods below the table are connected by a plate 18. The rods are reciprocated by toggle mechanism which includes a bracket 89 fixed to said plate 58 between the rods. A pair of toggle links 82 are pivoted at 8& to said bracket and have their upper ends disposed between and pivotally connected at 86 with the arm 88 of a bell crank lever. Said bell crank lever is pivoted on a shaft 90 carried by a bracket 92 fixed to the under side of the table 30. The long arm 94 of said bell crank lever extends rearwardly of the machine and is pivotally connected to the upper end of a rod .96. The lower end of the rod is connected to an eccentric strap 93 operating on an eccentric lei} loosely journalled on a shaft Hi2. Said shaft is rotatably supported in bearings HM, see especially Fig. 1, and is continuously rotated from the continuously rotating shaft 36 of the power mechanism by means of pulleys H16, ltd and belt H8.

The eccentric mil is adapted to be connected with the shaft 02 for rotation therewith by means of a ratchet I 52 fixed to the shaft on one side of said eccentric. A collar i M fixed to said shaft on the other side of said eccentric serves to hold said eccentric from axial displacement. Said ratchet H2 is provided with a series of teeth H6, four teeth being here shown. Said teeth are adapted to engage a pawl M8 fixed to a shaft l20 pivoted in and extended through the eccentric. Said shaft has an arm 522 fixed thereto on the other side of the eccentric which is engaged by a tension spring I2 3 that constantly biases said pawl for movement towards the ratchet. When the pawl is engaged with a tooth of the ratchet the ratchet and eccentric are rotated conjointly. When, however, the pawl is disengaged from a ratchet tooth the eccentric remains stationary with the eccentric at the top of its stroke. The reciprocation of the eccentric serves to straighten and collapse the operating toggle consisting of the links 82 and the short bell crank arm 88 and thereby to reciprocate the punch operating plate 72 with respect to the stencils.

The engagement of the pawl M8 with and its disengagement from the ratchet M2 is effected by means of an electromagnet E26 carried by the plate 18 and having an armature or core i228 movable into and out of the magnet. Said core is connected to and reciprocates a slide bar E30 which slides in a bracket l 32 fixed to the under side of said plate 18 and has its rear end disposed in the path of rotation of the latch H8. A tension spring 834 is connected with said slide bar I39 and serves normally to maintain the slide bar and the armature in a retracted position. In this position the rear end of the slide bar can be engaged by the latch H8 as it rotates. The operation is such that the rotation of the latch into engagement with the slide bar causes the withdrawal of the latch from engagement with a ratchet tooth, thereby freeing the eccentric from the continuously rotating shaft 862 and holding the eccentric and the mechanism associated therewith from further movement. When, however, the electromagnet I26 is energized the armature or core I28 is moved to retracted position and the end of the slide bar I30 is pulled out from under the nose of the latch I I8. The latch spring I24 then becomes operative to swing the latch into engagement with the ratchet to cause the latch to be engaged by a ratchet tooth and carried around therewith. The electromagnet is intended tobe but momentarily energized so that the slide bar is positioned in the path of rotation of the latch before the latch has made a complete revolution. Hence the slide bar is in position to be engaged by the latch and to cam it out of engagement with the ratchet upon the completion of a single revolution, thereby to stop further reciprocation of the mechanism. The bar also holds the mechanism stationary with the eccentric at the top of its stroke.

The punching mechanism, intended for operation by the reciprocation of the punch operating member I2 includes an upper die plate I36 disposed above and in engagement with the stencil track and suitably secured together and to the table '30 by fastening means I40. The upper die plate I36 is formed with or is so arranged as to provide an opening I42 through which the address bearing portion of the stencil is visible. The lower die plate I38 is provided with a series of, punch holes I44 therethrough corresponding in number to the perforation receiving zones 22 of the stencil and located tobe in register with the perforation receiving localities 26 of the stencil when the stencil is properly positioned in the punching position. The upper plate I36 is correspondingly formed with a series of guide holes I46. A series of punches I48 comprising cylindrical rods are reciprocable in said guide holes and through the stencils and into the punch holes I44. The upper ends of the punches are reciprocable in a pair of superposed guide plates- I50,

I52, respectively.

The upper guide plate, see especially Fig. 3, constitutes an index plate and bears consecutive numbers I54 adjacent each punch, the numbers corresponding with the numbers of the perforation receiving zones of the stencil so that number four punch, for instance, is the punch to be employed in perforating number four zone of the stencil.

The punches have outstanding flanges I56 intermediate their ends. Helical springs I58 encircle said punches below said flanges and bear against the flanges and the upper die plate I36, thereby to maintain the punches yieldingly in elevated 5 position out of the path of movement of the stenoils. The upper ends of the punches have cupshaped depressions I60 adapted to receive the end of a punch selecting rod or stylus I62 now to be described.

The means for transferring reciprocatory movement between the punch operating plate I2 and the punches includes the free punch selecting rod or stylus I62 illustrated particularly in Figs. 2 and 6. The rod comprises a cylindrical 5 metal bar of about the dimensions of a lead pencil having a pointed end I64 which is adapted to be seated in the cup-shaped depressions I60 of the punches and to beheld in engagement therewith as the rod is forced downward by the 7 reciprocable plate I2. The rod is adapted to be positioned manually generally vertically in engagement with a punch and immediately under the plate I2. Hence when the plate moves downwardly the plate transmits pressure through the rod to the punch and consequently moves the punch through the stencil therebeneath. The

operative of the machine merely has to position the rod into the cups of the successive desired punches and effect the momentary energization of the electromagnet I26 to effect a punching operation. Thus no particular manual labor is required on the part of the operative and the space between the punches and the plate I2 at all times is clear enough so that there is no danger of the fingers of the operative becoming injured.

While the operative may momentarily energize the electromagnet I26 in any suitable manner, it is preferred to effect the energization thereof through the instrumentality of the rod I62. To this end the rod is provided at its upper end with a vertically movable plunger I66 urged for movement outwardly of the end of the plunger by a compression spring I68 normally held from operation by the engagement of a spring urged latch Illi with a shoulder I12 of the plunger. When the lower end of the latch is depressed to free the plunger the plunger moves outwardly from the upper end of the rod into the position indicated by the dotted lines. The rod is somewhat shorter than the distance between the punches and the plate 12 and hence when in engagement with a punch does not engage the plate I2. When the operative, however, has selected a punch she momentarily depresses the lower end of the latch I I0. This releases the plunger I66 and causes it to move upwardly into electrical engagement with the plate I2. The circuit is thus completed through the electromagnet I26 as will be seen from an inspection of Fig. '7, and thus the plate I2 is caused to move downward. The downward movement of the plate I2 forces the plunger I66 inwardly of the rod and thus causes it to be automatically reset. Thus the plate I2 in its upward stroke moves away from the end of the reset rod and hence the circuit is interrupted.

Since the plate I2 only breaks contact with the upper end of the rod in the last part of its upward stroke and hence the electromagnet may not be deenergized soon enough, in a fast running machine, for the armature to be retracted and the slide bar I30 to become positioned in the path of movement of the latch IIB, before the latch has made a complete revolution, machine operated means is provided to interrupt the circuit sooner than it would be interrupted by the separation of the plate I2 from the rod, thereby to insure the withdrawal of the latch at the end of one revolution.

Said means includes a switch box I14 secured to the under side of the table 30 above and at one side of the path of movement of the lower plate I8 of the reciprocating unit, see especially Fig. 8. Said switch box contains the movable contact member I76 and the cooperating sta tionary contact member I18 which contact members are in series with the circuit I80 through the electromagnet I26 and the plate I2 and rod I62. An insulating contact button I82 is slida'bly carried by said box and bears against the movable contact member I76 in position to close the circuit when the button is depressed. The plate I8 carries a resilient laterally extended arm I84 which, when the reciprocating unit is in elevated position, is engaged with the button I82 and serves to hold the associated contact members closed so that the electromagnet is in condition to be energized by the operation of the rod I62. The arm I84 is adapted, however, to

release the movable contact member I16 as soon as the reciprocating structure has descended sufficiently for the latch I I8 to have moved clear from the slide bar I30, thereby to break the electromagnetic circuit independently of the rod. Thus the electromagnet has the greater part of the time of revolution of the latch I I8 to permit the retraction of its armature and the movement of the slide bar I36 into latch retaining position. This arrangement insures but one punching operation for each circuit controlling manipulation of the rod. With this arrangement of rod the operative has one hand free in which to hold or follow prepared lists of addresses and statistical items to guide her in the selection of punches.

After a stencil has been completely perforated the pedal 46 is momentarily depressed to effect the movement of the perforated stencil away from the punching position and the introduction of a new stencil into punching position.

While the machine herein described is particularly adapted for perforating address bearing printing devices it can also be used to perforate other types of cards.
