4 Claims.

My invention relates to that type of devices 11- lustrated and des Letters Patent No.

cribed in my United States 2,144,412, issued January 1'1,

1 939, which describes a device designed to slot or notch cards such as are set forth in United States Letters Patent No. 1,544,172, issued to Alfred Perkins. That patentdescribes a card which is provided with a plurality of perforations adjacent one or more of its edges, each perforation being located so that the material intermediate the edge of the card and perforation can be cut away thus forming a slot. Notching or slotting a plurality of such perforations,

forms a pattern of notches which refer to a single classification. When this is done, it becomes possible to sort a stack of mixed cards into a numerical or'other. desired sequence as more Perkins patent- The device of the Perkins patent fully set forth in the said has come into a very extensive use through the country.

These cards are relatively small in size and the perforations are closely spaced, therefore the slotting operation must be performed with a great degree of accuracy.

My invention has for its principal object to provide a slotting machine by the use of which it is possible to cut notches at a single A'further object or slot the entire pattern of operation of the device. is to provide a construction in which the danger of an inaccurate pattern is reduced to a minimum.

A further object is to provide a construction which can be adjusted to notch or slot any desired pattern.

A further object is to provide a device in which a plurality of cards may be slotted with the desired pattern without the necessity of resetting the machine.

A further object is to provide a resilient support for the punches which will be collapsed when the slotting operation is being performed.

My means of accomplishing the foregoing objects may be more fully comprehended by having reference to the accompanying drawing, in

which:

Fig. 1 is a side device;

view part1 in section of my Fig. 2 is a sectional view taken on-the line 2-2 in Fig. 1 in the direction indicated by the arrows;

Fig. 3 is a detailed view of one of the selecting Similar reference numerals refer to similar parts throughout As shown in the the specification.

drawing, the device comprises '(not shown).

a frame I which has a base 2, and a vertical portion 3. The vertical portion 3 is provided with an arm 4 which is cast integral therewith, or it may be formed in any other suitable or convenient manner. 5 This arm 4 is designed to carry a plurality of slotting punches 5,- which are slidably mounted in the arm 4. The punches 5 are held normally in an elevated position by means of springs 6,

one of which is provided for each of the punches 1o It will be seen from this description that, since the anvil 8 is cast integral with the base, it is .to all intents and purposes impossible for the card to get out of. position and thus produce an inaccurate pattern.

A lever I2 is pivotally attached to the vertical portion 3. A plurality of holes corresponding in number of the punches and in register therewith are cast or formed in the lever l2. This lever l2 has two downwardly depending portions l3 and it which have recesses I5 and it formed therein. These recesses arearranged to receive a selecting plate I1. An unlimited number of these plates I] must be provided, each one of which has punched therein holes I8 to permit the undesired punches to pass through theaplate, while the 'unperforated portions serve to actuate those punches which will slot the desired pattern when the lever is depressed. A handle [9 is formed on the lever '2 for the convenience of the operator 40 in slotting the cards.

Operation The operator having determined the pattern to be notched or slotted in the cards, selects the plate which will release or, render inoperative those punches which ,register with holes which are not to be notched or slotted and places it in the recesses 15 and It. A card is then placed on the die plate 9, to abut the upturned edge'50 II. The operator then depresses the handle is and the lever 12 through the selecting plate l1,

1 presses those punches which are requisite to notch the card and form the'required pattern. M the same time those not required are per- 2 I mitted to pass through the perforations in the selecting plate I]. r The downward movement of the punches 5 operates to collapse the springs 8 and on the operator releasing the handle the springs will return the punches to their normal position at which time the press is in readiness to repeat the operation if a duplicate or more cards are required. Otherwise the punches are in position to notch or slot the next pattern. In the drawing, I have shown only five punches but it should be clear that the number is to be determined by the pattern to be slotted or notched on the card.

Having described my invention, what I regard as new and desire to secure by Letters Patent is: 1. In a device for slotting cards, a plurality of slotting punches arranged in a substantially straight line, a frame comprising an arm which carries said punches, a, base, an anvil cast integral with said base, resilient means connected to said punches which collapse when the punches perform the slotting stroke, a die plate on said anvil cooperating with said punches, a pivoted lever having openings through which the ends of said punches may pass and arranged to effect a slotting stroke of said punches when said openings are covered and said bar is depressed, there being recesses in said lever, and a series of individual selecting plates adapted to be inserted in said recesses to operate punches to form a pattern of notches in the edge of the card to be slotted.

2. In a device for slotting cards, a plurality of slotting punches arranged in a substantially straight line, a frame comprising an arm which carries said punches, a base, an anvil-cast interal with said base, resilient means connected to said punches which collapse when the punches perform the slotting stroke, a die plate on said anvil cooperating with said punches, means on said die plate which form an abutment for the card to be notched, a pivoted lever having openings through which the ends of said punches may pass and arranged to effect a slotting stroke of said punches when said openings are covered and said bar is depressed, there being recesses in said lever, and a series of individual selecting plates adapted to be inserted in said recesses to operate punches to form a pattern of notches in the'edge of the card to be slotted.

3. In a device for slotting cards, a plurality of slotting punches arranged in a substantially straight line, a frame comprising an arm which carries said punches, a base, fixed means to support a die plate on said base, resilient means connected to said punches which collapse when the punches perform the slotting stroke, a die plate cooperating with said punches, a pivoted lever having openings through which the ends of said punches may pass and arranged to eiiect a slotting stroke of said punches when said openings are covered and said bar is depressed, there being recesses in said lever, and a series of individual selecting plates adapted to be inserted in said recesses to operate punches to form a pattern of notches in the edge of the card to be slotted.

4. In a device for slotting cards, a plurality of slotting punches arranged in a substantially straight line, a frame comprising an arm which carries said punches, a base, an anvil cast integral with said base, springs connected to said punches and said arms which collapse when the punches perform the slotting stroke, a die plate on said anvil cooperating with said punches, means on said'die plate which form an abutment for the card to be notched, a pivoted lever having openings through which the ends of said punches may pass'and arranged to eflect a slotting stroke of said punches when said openings are covered and said bar is depressed, there being recesses in said lever, and a removable selecting plate adapted to be inserted in said recesses to operate punches to form a pattern of notches in the edge of the card to be slotted.
