11 Claims.

The invention relates to perforators and has more particular reference to a machine of this class for perforating cards and the like with a plurality of parallel slots which may vary in length within the capacity of the machine and wherein a round opening will be simultaneously punched in advance of each slot.

Perforating machines as heretofore constructed have used a plurality of punches which, when actuated, would perforate a sheet such as a bill, label or the like, with round openings. These-punches in the conventional type of perforator are actuated by an oscillatable head comprising control members which can be set so as to cause actuation of selected punches for perforating the date or other information in the bill or' label.v It vis possible in the machine of the present invention to select desired punches for actuation but the selection is made by moving adjustable slides, each of which carries a group of punches. One or more punches of the group, depending on the extent to which the slide is pulled, combine to punch a slot in the card or the like, and which will be parallel with the slots produced by the other slides. n

Accordingly, an object of the present invention is to provide a perforating machine for punching a card or the like with a number of parallel slots which will be uniform in width but which may be varied as to length within the capacity of the machine.

A more specic object of the invention is to provide a perforating machine for punching a card or the like which will punch a number of parallel slots in said card of uniform width but which may be varied as to length, depending on the position of the slides corresponding to said slots and wherein a round hole will also be punched in said card in advance of each slot.

Another object of the invention is to provide a perforating machine having a plurality of adjustable slides each carrying a group of punches for perforating a slot in a card or the like and which can. be operativelypositioned or inoperatively positioned as desired.

A more specific object resides in the provision of a perforating machine having independently adjustable slides for rendering operative one or more punches of a group, depending on the extent to which the slide is pulled out and which will also incorporate novel die structure for association with said punches wherein the die opening for each slide will automatically increase in size as the slide is pulled out and decrease in size as the slide is returned.

A more specic object is to provide a perforating machine for the purposes described which will embody novel die structure comprising a movable die for each adjustable slide, having coaction with a stationary die and wherein three edges of a slot will be cut by the stationary die and the fourth edge by the movable die.

With theseand various other objects in View, the invention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specication, drawings and claims appended hereto. l

Figure 6 is a horizontal sectional view throughv a group of three individual slides showing a modified arrangement of dies for co-acting with the punches of the slides; and v Figure 7 is a planviewof a card perforated with a number of parallel slots by the machine of the present invention. l

Referring to the drawings,which illustrate one embodiment of the invention, the frame ofthe present machine consists of base members I0 and II positioned on the respective sides of the machine and extending the length ofthe body portion thereof as shown in Figure 1.,' These base members have suitably secured thereto the side frames I2 and I3 which are joined at their upper end adjacent the front by the rod I4 and adjacent the rear by rod I5. Said rodsk are threaded at their respective ends and theseends receive the nuts t6 securely holding said rods in place. The sides frames I2 and I3, which are secured to the base member by rivets I'I, have a shape which is best illustrated in Figure 1 and which is substantially the same in outline as that of the individual slides confined between said side. frames and which will be presently described. It will be `apparent from Figure 1 that the frames I2 and i3 extend beyond the rear of the base members Il! and II. Positioned to the inside of each side frame is a member I8 and I9, respectively, which maybev described as alsuport member and which has direct contact with an end slide. The shape of said bearing members is substantially that of a side frame although in certain particulars they differ in general outline. The rivets 29 secure the support member I8 to its side frame I2 and rivets 2l in like manner securely join member I9 to its side frame I3. It is also noted that the upper ends of said members terminate substantiallyush -with that of the frame and are apert'ured for receiving the rods I 4 and I5. The side frames at their lower ends are grooved, as clearlyshown in Figure 3, for receiving the outwardly bent flange 22 formed on the sides of a metal container identified by numeral 23 having a knob 24. In this manner the container is supported for movement so that the same can be withdrawn and replaced and it will be understood that space is provided by the base members I and I I within which the container is located.

The punches of the present perforating machine are actuated by a force plate 25 which is suitably secured as by welding to the top member 26 of a movable frame which is reciprocated in a vertical direction by the plunger 2'1. The movable frame is completed by the depending side members 28 and 29 and which are provided at their lower ends with an inwardly directed ange portion 3G. The

depending side members 29 are positioned to the outside of the side frames I2 and I3 and the anges 30 are also spaced in the side frames so kthat the movable frame will` be free of any obstructions or interference to its movement. It will be understood, as best illustrated in Figure 2, that the inwardly directed flanges 35 of the movable frame provide a support for the transverse bars 3| and 32 which are suitably secured to the depending side members 28 and 29 by the screws 33 and which are positioned forwardly and rearwardly of said movable frame, respectively.

In the present perforator the carriers for the punches consist of a plurality of individual slides identified by numeral 34. The general shape of the slides, as will be clear by reference to Figure 2, is rectangular, each slide having extending from its upper forward end a portion 35 to which is fixed the actuating knob or handle 38. Each slide `'substantially centrally thereof is provided with an and the lower portion 4B, respectively, of the slide land these punches are in line so that each has contact with an adjacent punch. Each slide also Vcarries a round punch 4I, which is located forwardly of the square punches a very short distance andaligned therewith. The round punch is peculiar to the present embodiment and this element may be omitted without materially departing from the invention, since the square punches operate the same in both cases. All the punches lare inoperatively positioned when the slide is in, that is, located inwardly as far as the slide will go, and it will be observed that to render the `round punch inoperative the force plate 25 is -provided with a plurality of round bored openings 142, each being in alignment with an end Vof small diameter formed on the round punches.

- Elongated openings 43 are provided in the forthe spring 49 and said cover is supported by the side frames I2 and I3. The slides may be pulled out one, two or more notches and this will render operative the round punch and one square punch or said round punch and two square punches, etc., depending on the number of notches to which the slide is moved. Downward movement of the force plate will produce similar movements of these operatively positioned punches. To perform a perforating operation it will be observed that movement forwardly of the slide will locate the round punch out of alignment with opening 42 and therefore 'this punch and the square punch, which may be located under said opening will be actuated.

For lifting the punches that have been depressed vthe invention provides pins 48 projecting from the sides of each punch. These pins overlie and normally contact lifting bars 50 which extend between the punches of adjacent slides and of course below the pins. Said bars 5G Vare fixed at their ends to the transverse bars 3| and 32, respectively. As the force plate and the movable frame move downwardly for a perforating operation the bars 50 have similar movement and therefore no interference is presented to the actuation of the punches for perforating a card or the like. However, as the movable frame moves upwardly the bars 56 are brought into contact with the pins 48 and the punches are lifted from the die openings and returned to initial position. In this position they may be operated. again if it is desired to punch another card or the position of the slides can bechanged before the force plate is again actuated.

Dies are provided in the present perforator for association with the punches to punch the round openings and the parallel slots, As the slides 34 are pulled out a larger number of square punches are rendered operative and accordingly the die opening must increase in size to accommodate this larger number of square punches. The preferred modification shown in Figures 2 and 4 includes a stationary die 5I having die openings 52 extending inwardly from its forward edge. The openings each receive a movable die 53 carried by the slide and which has a width and length to completely fill the die opening when the slide is inoperatively positioned. In this position the forward cutting edge 54 of the movable die is in contact with the rear cutting edge 55 provided by the stationary die. However, when the slide is pulled out the two surfaces separate, forming a slot to accommodate the square punches. For the round punch each movable die has a round die opening 56 which at all times is in alignment with the round punch. Each movable vdie is integral with a supporting portion 57 secured by screws 58 to the base section 6|] of its slide. In the form of the die structure shown in Figure 4 the stationary die will cut three edges of a slot and the fourth edge will be cut by the movable die.

Figure 6 shows a modied form of die structure wherein the .parts are. reversed 'from that ofFigure 4. vThe stationary die 6I .provides the male '75 Figures 4 and 6.

members 62 which t within a die-opening 63 formed in each movable die 64. Round die openings 65 are also located in the movable die so that these maintain their position with respect to the round punches. In this modification three sides of each slot in the card are cut by the movable part of the die structure and the fourth or rear edge is cut by the stationary die.

In. both forms the stationary die is suitably supported from the supporting members I8 and I9 by means of projections 66 which have intertained in inoperative position such as shown in full lines in Figure 2. Although the round punch -is located under the force plate 25 when the slide is in the opening 42 receives the reduced end of the punch and the same is not actuated.

However, when the slide is pulled out the round punch and one or more of the square punches are operatively located under the force plate 25 and downward movement of the movable frame will actuate the same to perforate a round opening in a card or the like and to alsqperforate a slot. The card to be punched is inserted in the perforator and properly positioned therein by the rear edge 68 of the perforator opening 69. This opening is provided for the'full width of the perforator, being formed in the slides and also in the supporting members I8 andy I9 and the side frames l2 and i3. With the card thus properly positioned the. desired slides may be pulled out to perforate parallel slots in the card and wherein each slot has associated therewith a round opening. This will be evident from Figure '7 in which the card 'IU is perforated with parallel slots 'H of variable length and wherein each slot has a roundopening 12 immediately 4below the same. The cards may be used for keeping inventory and the like, in which case the cards are printed with numbers arranged in columns, each column beginning with the numeral 9 at the top and ending with numeral l` at the bottom. In order that the operator will know to what extent the various slides must be pulled out for punching a slot of desired length the side frames l2 and i3 support a wire marker 13, Figure 2, extending transversely of the frame, and ealch slide is marked on its upper surface with a column of numbers such as appear on the card although in reverse order. When the slide is pulled all the way out the entire column will be perforated. When the slide is moved part way as, for example, when the numeral 6 appears beyond the wire marker 13, this will indicate that said slide will punch a column of numbers down to and including numeral 6. This numeral will be punched with a round opening and the slot will be punched by three square punches.

When the various individual slides are operatively positioned it will be understood that the particular die structure for each slideautomatically provides a die opening of a size to accommodate the operatively positioned punches. In both forms of structure shown in Figures 4 and 6 alignment with the round punches 4|.

a round die opening is formed in the movable member and therefore these openings maintain Each elongated die opening for the square punches of a slide progressively increases in length as the slide are pulled out to accommodate the increasing number` of square punches which are rendered operative by movement of the slide in this direction.
