A: CORPORATION OF DELAWARE CARD PuNcH Application filedDecember 1a, 192a, Serial NO. 681,334. 1-

My invention relates-to machines for op,- erating punches, andbroadly stated, it comprises punches which are operated from a suitable source of power and' keys manipulated by an operator, each of which, when operated, causesthe source of power to actuate the punch. My invention is particularly useful for punching holes in cards which are used in tabulating and similar machines.- I

will describe a machine embodying my invention and then point out the novel features thereof in claims. 1

In the'accompanying drawings, Fig. l'is a plan view of a machine embodying my invention, and for illustrative purposes shows amachine'for'punching holes in cards. Fig. 2 is a front elevation of the machine of Fig.1, exceptthat the keys are in section, the section being taken on the line 2-2 of Fig. 1. Fig. 3 is anend View of the machine, with one key depressed, and taken partly in section, the section being takenvon the line 33, of Fig. 1. Fig. 4 is a sectional view of the machine of Fig. 1, the section being taken on the line 44 of Fig. 1. Figs. 5,6 and 7 are each detail views showing different. positions of the punching and escapement mechanisms.

Inthe drawings the keys 20 rock'on rods 21 and are held up in engagement with the rods 21 by compression springs 22. Extending upwardly from the central portion of each 23, the upper ends of which are guided by slots in a plate 23a suitably supported from the framework of the machine. Each rod 23 has extending from one side a shoulder 24 and pivoted to the'rod is an arm 25. Thefree end of each arm 25 is bent so that it will engage with the corresponding shoulder 24 (see Fig. 5) andeach arm 25 is normally held in'engagement with the shoulder 24 by a spring 26. Extending. across the ofthe device are a series ofbars 27,

each of which, at one end, is pivotedto'a bell crank lever 28, and near the other end is pro-. videdwith a cam shoulder which is normally pressed against shoulder 24 by a spring 29. It is to be noted that each arm 25-extends slightly ,beyond the corresponding shoulder 24 (see Fig. 3) ,so that the end ofeach'of these arms rests upon a bar'27. As's'hown in Fig. 3,

.and cause a be arranged in spaced if a key 20 is depressed, shoulder24 ebrresponding to such key will drop and the shoulder 30 of bar 27 will be drawn in between shoulder 24 and arm 25 by the action of the spring 29. Each bar 27 also carries a projection 31, which, when the bar 27 has moved forward between the shoulder 24 and arm 25 (see Fig. 6) will engage the corresponding tooth group 32. i

36 designates a, suitable source of power, here shown as being an electric motor, the armature of which drives a shaft'35, carrying a-bevel gear 350: which meshes with a bevel gear, 34. The bevel gear 34 isfast on a shaft 33 which is suitably mounted in the frame;

work of the machine. The shaft 33 is pm fvided with a plurality of groups of teeth 32,

one group being provided for each mechanism through which a punch is operated. When the machine is in operation the groups of teeth are rotating rapidly. As soon as engagement occurs between a projection 31 and a tooth of a group 32, the bar 27 is pushed" toward the right. The pressure exerted on .bar 27 will cause bell crank lever 28 to oscillate about shaft 37. Pivoted to the other arm of the bell crank lever 28 is a bar 38 A secand 7, a movement of bar 27 to the right,-by causing bell crank levers 28 and 39 to oscillate, will move bar 38 toward the back of the machine. 'Operatively connected with each i bar 38 is a plate 43 carrying a pin 44 Each pin 44 mounted inpunch plate 46. It is thus apparent, that the backward movement of bar 38 resulting from the. depression of the corresponding key 20 will immediately result in the; operation of the corresponding punch 45 tioned in card rack 47. I 7 7;. g

In devices of this kind it is ordinarilyde sirable that the holespunched in the cards columns. In order to accomplish this, plates 43 and punch plate are mounted On a movablecarriag'e'48.

is positioned opposite a punch 45v p on shaft 52 and engages with a rack 53.

Carriage 48 is drawn toward the right hand end of the machine by a flexible strap 49 which passes over pulley 50 and is connected with a spring 50. Carriage 48 is held in its initial position by a dog 51 which is fiizled X- tending up from dog 51 is a pin 54. An

escapement member 55 is fixed on shaft 56- and at one end it engages with pin 54 and has the other end so shaped as to engage with rack 53. When shaft 56 is rotated in a counter-clockwise direction, escapement member 55 will engage with rack 53 and dog 51 will be lifted from the rack, thereby permitting the carriage 48 to advance one tooth space. Fixed on shaft 56 are a series of arms 57 each carrying a pin 58. Each plate 43 carries an extension 59 adapted to engage with a corresponding pin 58; accordingly the normal movement of a key 20 will not only cause a hole tobe punched in the card but will result in the carriage being advanced one tooth space. In order that it may be possible to advance the carriage rapidly from one group of indications to another, I provide a special group spacing key 20. This key, like the others, is connected to a bar 27 which has a plate 43 corresponding with plates 43. It does not, however, engage with any punch corresponding to punches 45. Plate 43" carries an extension corresponding to extensions 59 and likewise carries an additional extension 60 which is adapted to cooperate with pin 61, mounted on arm 62, fixed to shaft 63. A movement of shaft 63 in a counter-clockwise direction will cause dog 51 to become disengaged from rack 53 without permitting escapement member 55 to engage with the rack, so that the carriage will be drawn to the right until trip member 64 engages with a sto 65 which has been fixed in a predetermine d position. The connections between shaft 63 and dog 54 follow standard practice in this art, and accordingly thedetails of such connection are not shown in the drawings.

It will be noted (see Fig. 7) that when bar 27 has been pushed to the right by the action.

of a cam wheel 32, shoulder 30 will pass from between the corresponding shoulder 24 and arm 25. This will permit the corresponding key 20 to assume its original position. As soon as such cam wheel 32 passesfrom enagement with the projection 31, bar27 will edrawn back to the left by the action of a spring 66. As the bar 27 is drawn back to the left the cam surface of shoulder 30 will strike against the shoulder 24 and arm 27 will be pushed back clear of cam wheel 32. The return movement of arm 27 will cause bell crank levers 28 and 39 to return to their original positions and carry back with them In order to assist in setting the machine, it may be provided with a spacing key 20". This key has pivoted to it a link 67, to which in turn is pivoted a lever 68. Attached to lever 68 is shaft 69. Shaft 69 carries arms 70 and 71 between which is mounted a rod 72 which is adapted to cooperate with a pin 73 connected to escapement member 55. By clepressing key 20 the escapement mechanism is operated to advancethe carriage 48 one tooth space.

It is to be understood that the foregoing example is given for purposes of illustration only, and it is not intended thatmy claims shall be limited to the V exact construction shown, for those skilled in the art will readily be able to modify the construction in many details without departing from the spirit of my invention.
