D. A. NEVIN CARD PUNCHING MACHINE Filed Apr'il 20. 1945 2 Sheets-Sheet 1 ATTORNEY Jan. 21, 1947. D. A. NEvlN CARD PUNCHING MACHINE Filed April 20, 1945 2 Sheets-Sheet 2 vatented `an. 21, 1947 UNITED STATES PATENT OFFICE 20 Claims.

My invention relates to that class of card punches described in Welk Pat. No. 1,981,932 and Welk and Nevin Pats. Nos. 2,062,153 and 2,062,157, which punches are designed to punch notches in the margins of cards such as those described in Perkins Pat. No. 1,544,172.

As is well known, these cards are furnished to the use in the printed and perforated form and a keyboard controlled notching punch is rented to large users for notching such cards from a perforation to the adjacent margin of the card, while the smaller and more numerous users notch their cards with a ticket punch similar to those used by train conductors. Frequently there are dozens of holes to be notched out in a single card, and the manual operation of notching hundreds of them causes severe fatigue and slows up the entire procedure. It is an object of this invention to provide for speedy operation of a commercial ticket punch, with avoidance of fatigue and with Very accurate punching, a preferred means for actuating the punch being a solenoid, though other electrical or mechanical means may be employed. Y

It is very necessary thatl the notches should be accurately cut and spaced, all as provided for in the larger key punches, and it is a further object of my invention to provide means whereby the low cost ticket punches referred to may be made to punch out the perforations to a uniform distance from a margin of a card, and to space the notches accurately without resort to elaborate mechanisms such as the escapement described in my Patent No. 2,041,085.

The perforated keysort card, when punched in a keypunch of the type described in the abovementioned patents, is dropped into a slot and is punched blind. Users of the ticket punch favor visibility as in hand punching but for the tiresome effort required. It is a still further object of my invention to provide means whereby that ,card margin that is being punched is Visible to the operator when the card is in position to be punched.

Another object is to provide a, simple escapement mechanism that permits of indexing a card either to the right or to the left for a distance equal to that from one hole of the card to the next.

Another object of the invention is to provide means whereby the card holder can be freed instantly from the escape mechanism to permit replacement of the holder, e. g., in a position equivalent to the indexing of four perforations (one eld) to right or left, or to any other distance. Such ready detachability permits a card holder to be exchanged with facility for another of greater or less length, according to the length of the cards to be punched.

The means for accomplishing the foregoing objects may be more readily understood by reference to the accompanying drawings, which are made a part `of this application, and in which similar' reference characters indicate similar parts. In said drawings: A

Fig. 1 is a front elevation of my notching device, with a card of the type used in needle sorting shown in position tobe punched, parts of said device being broken away, i

Fig. 2, a vertical section on line lil-i 0' of Fig. l, exposing the ticket punch operating mechanism,

Fig. 3, a full scale perspective of a card indexing detail,

Fig. 4, a vertical section of a modified form of the invention, parts being omitted, and

` Fig. 5, a section on line 5-5 of Fig. 4.

As shown in Fig. 1, a card Il is provided with ene or more rows of conventional perforations arranged in groups or elds adjacent and parallel to one or more of its edges, numerals 1, 2, 4 and '7 being printed on the card adjacent to the corresponding perforations of each group or eld. Various combinations of these perforations are notched through an edge to form a pattern or code representing certain values, thus providing for needle sorting of the cards into predetermined sequence. Or single perforations may be notched, each notch representing a Value.

The card il is inserted into a holder l2 consisting of a. back plate I3 with right and left guides i3 attached thereto by means of rivets I3 or by spot welding. The guides I3 provide guiding spaces somewhat thicker than the maximum thickness of any card to be punched.

Overlapping ears are indicated at I4 and are secured to plate E3 by means of rivets I3. These ears serve to retain the card which rests upon the upper surface of a shoulder formed on the cover I5. The card holder i3 has a rack l attached to its rear face by rivets Il, said rack overhanging a vertical flange of an L-shaped angle iron 2 I, said rack being shaped with approximately half-cir cular scallops in its lower edge, as indicated at i8, for the purpose hereinafter described. The lower edge of rack I6 in its normal position rests upon a track I9 which is riveted to the L-shaped iron as at i9. The angle iron and track extend beyond the frame of the device at right and left for a distance suicient to provide for the `largest sizes of cards'thatare to be` punched.

The rack I6, las clearly shown `in Fie. 2, is

formed with an offset which is bulged out to the right in Fig. 1 for an amount sufficiently greater than the thickness of the upright flange of the angle iron 2I to permit the assembled card holder to be moved freely from right to left and vice versa or to be removed by simply lifting it upward from the guide flange, which is straddled by 'the back plate I3 and the rack It. This feature permits the exchange of card holders for different sizes of cards, and also permits the operator to shift the holder 'and its card readily to any desired extent.

For holding small cards in place in a card holder that is too large for them I provide a spring clip 22 which is secured to an ear I4 by"rivets 22. This means also provides for retention of a card in the holder I2 when the card is inserted endwise, assuming that the height of the card is not so great as its width. The holder is then posisitioned to place the card behind the punch and in front of the die 24 of the punch hereinafter described.

The indexing device shown in Fig. 3 may be compared to a pinion with two teeth that are milled from one piece integral with the shaft 25 as indicated at 25', or which may be attached thereto as rollers by means of shouldered screws (not shown). In assembly the axis of shaft 25 lies in a plane where the lower edge of rack It; contacts with the upper edge of the track I9.

In Fig. 1 a half circular clearance cut in track I@ is indicated at I9, permitting the pinion to be rotated. A half turn reverses the positions of the teeth 25' and causes the rack I6 and the card holder with its card to be indexed to the right or the left depending upon the direction of rotation of the shaft 25. It is obvious that the distance between the centers of the pinion teeth 25 must correspond to the pitch of the rack teeth I8.

Referring to Fig. 2, motion is transmitted to shaft 25 from a vertical shaft 26 by means of miter gears 2I. In Fig. 1 a, section of the cover I is broken out to show the vertical shaft, which is driven in either direction by means of a hand knob 28, pinned to a shaft 29, through the medium of miter gears 3D.

Rapid rotation of knob 28 causes the rack I6 and card holder to move rapidly over several spaces so that a eld of four holes in the card (corresponding to 7-4-2-1 in the system) may be indexed as readily as from one hole to the next one.

There are many instances where a card is to be notched with one or two notches at the extreme left and similar notching is desired at the extreme right. To obtain this result it is not necessary to rotate the knob 28 for moving the card and its holder for the entire distance, but the holder with its card may be lifted by hand suiciently high to free the rack I6 from the gear 25 and then the holder may be moved to desired position before again lowering it into position for engagement of the rack with said gear.

In Fig. 2 the ticket punch 3| is attached to a base 32 by means of a bracket 33 and rivets 33'. One handle 34 is shortened for clearance purposes and is connected by a link 35 on a pivot pin 33 to a lever 39, the link being held in a position for opening the punch by separating the punch jaw 23 from the die 24, as by a spring 31 anchored to a post 38.

The lever 39 is pivotally supported on a shaft lil which is supported at its ends in bearings on the frame or cover I5. To the lower end of lever '39 there is attached by means of a cond necting link 43 a, plunger 4I extending from a solenoid 42.

The solenoid d2 is motivated by electric current supplied through the normally open blade switch which is closed by movement of the tail 45' of one of two levers @5 which are connected outside of the device by the strip 46 on which is located the pad il of rubber or plastic by means of screws (not shown). rIhe coil spring 48 draws the tail 55' downward to open the switch, which is therefore normally open.

The spring 48 is attached to the base 32 by means of a spring clip 49 as shown. The spring post 3S is threaded or driven into the upper part of the solenoid t2. The downward movement of the lever d5 is limited by contact with the bottom of its slot 65".

The pinion shaft 25 rotates in a bearing block 5d which is affixed to the top cover I5 by screws 5I which pass through angle iron 2l. A separate cover for this mechanism is indicated at 52. The vertical shaft rotates in a bearing bushing 53 which is riveted or welded to top cover I5. A similar bearing bushing is provided for shaft 29.

A drawer 55 extends across the interior of the device and is inserted through an openingin the rear.V A knob 55 is provided for convenient removal of drawer 55. Rubber feet may be used 0n the frame, as indicated at 5I.

In the modied form of Figs. 4 and 5 the ticket punch is mounted as before. The spring 58 is a conventional part of a commercial punch of conventional character. The elongated hub of the hand lever 5@ is pivotedv to a side wall of theV casing by the shouldered bolt E@ and the nut 5I. The lower end 0f the arm 52 of the punch is loosely fitted into a slot 63 milled into the hub of the manually operated lever 59. A slot 64 is provided in the front of the casing for movement of the operating lever 59.

It is contemplated'that the modification of Figs. 4 andV 5 could be arranged for operation by the foot of the user, and that either form can beY actuated in any of various mechanical methods, as will be obvious. It is also believed tobe obvious that many other alterations may be made in the device, all without departing from the spirit of the invention, and therefore I do not limit myself to what is shown in the drawings and described in the specification, but only as indicated in the appended claims.
