Application'filed April 18, 1925.

This invention relates to machines for punching holes in cards and stenclls, and 1s partlcularly adapted for making code punch.-

mgs in cards and stencils used in controlling selector mechanisms, such as addressing machines, tabulatingmachines, weaving ma chines,and the like.-

The main objects of' this invention are to provide an improved form and arrangement of punches; to provide improved mechanism for selectively operating said punches; to provide improved means foraccuratelyguiding a series of cards past a fixed point along a definite path and for momentarily holding a card at said point while it is being operated upon; to provide improved operating mechanism tor intermittently actuating said holding means; to provide operating mechanism of this kind controlled by the movement of the punching mechanism so 'as to inpositioning of the card at the critical moment; and to provide improved mechanisms and'means of thiskind whereby two adjacent cards may be operated on simultaneously. I

Fig. 11 is an enlarged detail of the card positioning mechanism:

Heretofore, stencils and cards used in controlling selector mechanisms usually have been punched by hand, while being held in a suitable master plate or templet. The machines, sometimes used for making punchings, heretofore have consisted of a single punch which in some cases was laterally shiftable across the'templet, while, in other cases, the templet or master plate and the card to be punched were'laterally shiftable relative to the punch. Such prior forms of punches have been very and otherwise generally unsatisfactory.

In the specific construction herein shown, the present invention is applied, to a punching machine having improved mechanism for selectively operating a battery of punches so that a series of cards or stencils may be fed through the machine in continuous, rapid succession.- The cards are fed from a magazine or hopper (not shown) along a guideway in a step-by-step movement to the'punching position Where they' nism which is controlled by the operation of the'punches so that, upon each down stroke of the punches-the holding means is actuated to effectively hold the card or cards operated upon.

In the specific construction herein shown, machines comprises a frame 1, having a horizontal guideway 2, along which a series of cards or stencils 3 upon by one or more of a battery of punches 4 which are arranged for selective operation through the movement of a vertically reciprocating head 5, which is mounted in the frame 1. Arranged adjacent the guideway 2, is improved holding and positioning means 6 adapted to momentarily hold two adjacent cards 3 punching operation. The holding means 6 the vcode in rapid succession 1 'statlonary during the ill by this machine,

'retaining them on the is intermittently actuated by improved mechanism 7 controlled in its operation by the movement of the head 5.

As herein illustrated, the frame 1 comprises'a base plate 8 and a top plate 9 connected together by upright posts 10 which slidably support the head 5.

The guileway 2 is formed in a pair of spaced guide blocks 11 and 11.1 which are rigidly mounted on the base 8 and secured thereto by bolts 12 or other suitable fastening means.

One form of stencil adaptedto be punchel and which is in common use in addressing machines, is shown in Figure 3. This stencil con'i'prises'a thin membrane 13 mounted in a cardboard frame 14 having a recess 15 in one edge thereof which forms a sight opening through which the index cards may be visualized when the cards and stencils are stacked vertically, as is well understood. Formed in the frame 14, are apertures 16, or code punchings, the

positions of which determine the selection, as is also well understood in the art, and which may be arranged so close together as to overlap-one another to provide for a large number of classifications or selec- The punches 4 are arranged in two rows,

extend-through openings 17 1n the guide: blocks 11 and 11.1. Formed in the base plate 8, in register with the openings 17, are apertures 18 to'rec-eive the lower ends of the punches 4. The upper ends of the punches 4. are provided with heads 19 for head. The space between adjacent punches 1s equal-to the distance between alternate apertures 16 in the card or stencil ,to be operated upon, and fbr this reason the punches are arranged in two groups, as shown in Fig. 10,,so" as to be adapted to operate on two stencils simultaneously, ()ne group of the punches 4 is located adjacent one end of the guideway 2 for punching alternate apertures 16 in the cards 3, while the other group of punches is located adjacent the other end of the guideway for punching the other set of alternate apertures. For instance, apertures locatedin'positions 1, 3, 5, 7 ,9, etc. on the card arepunched while the card is held at one end of the guideway 2, while the intermediate apertures located in positions 2, 4, 6,8, 10, etc. are punched while the card is held at the opposite end of the "uidewa With this nn roved arran ement b D of punches it is-possible to punch apertures which overlap one'another which would not be possible with a single set of punches without providing for a relative adjustment between the card and punches.

In the specific construction herein shown,

the head 5 is in the form of a reciprocatarm 24, which is oscillated by they reach I,

'ing carriage comprising a horizontal plate 20 having bosses or'bcaring parts 21 which slidably engage the upright posts 10 of the frame 1. Projecting upwardly from the plate 20, is a pair of lugs 22 connected by links 23 to the ends of a fork-shaped rocker any suitable means, not shown, for continuously reciproeating the head 5. v

- Suspended from the plate '20, by bolts 25 or other suitable fastening means, is a supporting plate 26, having two rows of apertures 27 forming seats or loosely supporting the punches 4 is spaced from the plate 20 by suitable washers 28 so as to permit the punches 4 to move axially relative to the head. relative. movement of the punches and head, permits those punches whichare not in the particular selection, to rest onv top of the stencil frame 14, while the head 5 continues its downward movement and while the selected punches are bcing'forced downwardly through the stencil frame 14. To selectively operate the punches 4, they are snostantially locked against axial movement, relative to the head 5, by means of keys or wedges 2!) which are individually insertable between the heads 19 of the punches 4 and opposed parts of the are seated in horizontal seats or opemngs 30 formed in a pair mounted on the lower face of the plate 20. To secure the 'keys 29 against accidental dir-aplacement from the seats 30, they are head 5. The keys 29 of spaced blocks 31 The supporting plate 26 This ill)

provided with notches 32 Y in their upper I edges, which engage spring pressed balls 33 seated in openings 34 of the blocks 31.

are adapted to engage the heads 19 of the punches 4 to hold the selected punches in their downwardly extended positions relative td the head 5. If desired, the keys 29 may be operated by a key board control mechanism, not shown, which will enable the operator tochange the keys and corresponding punches more rapidly.

The cards and stencils are fed along the guideway 2 in a step-by-step movement, by any suitable means, not shown, and when the punching position, the two adjacent cards located directly beneath the punches engage a pair of steps 38 against which they are urged by the improved positioning means 6.

The stops shown in our copending application,- Serial No. 746,808, filed October 30, 1924. These steps are in the formof bell crank levers lo- 38 are substantially like those into the path of the 39 of the rear guide block secured to the block by pins of each of the levers 38is, shoulder 42 which projects stencils for successively halting them as they reach the critical'point where they are to be acted upon by the punches. The shoulders 42 are yieldingly held in operative'position by tension springs 43 which are connected to pins 44 mounted on the block 111 and the outer arms 45 of the outed in recesses 11 and pirotally it). One arm 41 provided with a bell crank levers 38. lVhen the cards are.

forced forward from one position to the next, the levers 38 are forced back against the action of the springs'43 so that the tips of the shoulders 42 ride on the edges of the cards until they drop into the next corners In the specific construction herein shown, the improved positioning means 6 includes a pair of fingers 46, the ends of which are shiftable in recesses 47 formed in the guideblock 11.1, for engagement withthe stencils 3 to urge the stencils transversely into lirm engagement with the guidcblocks 11 and t'orwardly into engagement with the shoulders 42 of the stops 38.- The recesses 47 are spaced apart substantially the length of a stencil. in order to preventpossible injury to the cards by, a positive action of the fingers 46, these fingers are pivotally secured to one end of a pair of levers 48 by pins 49. The levers 48 are pivotally secured to the base plate 8 by pins 50. Bearing between the other ends of the levers 48, and the guideblock 11.1, are compression springs 51 which normally urge the pivot pins 49 of the fingers 46 toward the guideway. In order to-operate both of the fingers 46 simultaneously, they are connected by a link coupling including arms 52 and 53 pivotally connected to the pins 49 ot' the lingers 4b. and connected together by a link 54. The arms 52 and 53 are 'spacedabove the fingers 46 by suitable washers 55 embracing the pins 49. Embracing the washers 55, are springs 56 which bear against studs 57, 58 and 59 respectively mounted on the fingers 46 and arms 52 and 53. The springs 56 form a; yielding connection between the fingers 46 and arms 52 and 53.

In the. specific form shown, the operating mechanism 7 for intermittently actuating the'positioning means 6, includes a vertically disposed rock shaft 60 journaled in the frame 1, and a vertically reciprocating cam 61 pivotally mounted on a bracket 62 which pro-v jects upwardly from the head 5. Fixed on the lower end of the rock shaft (50, is an arm (33 which is connected to the arm 53 by a link 64, so that the rocking of the shaft GO causes a rocking of the arms 52 and 53 around the pivots 49, and a rocking of the fingers 46 through the spring connections 56. The rock shaft 60 an'd fingers 46 and the intermediate link coupling are normallyurged to actuate the fingers 46.

.69, 'therollerreturns to its cam (31 has passed above the ment by the punches.

into the retracted position, shown in Figure 10, by a sprihg 65 which is connected at one end to a stud 66 mounted on the base plate 8 and at its other end to a pivot pin 6'? which connects the link 54 to the arm 53. lliounted on the shaft 60, is a pin 68 carrying aroller 69 arranged to engage the cam 61 upon each down stroke of the head 5, for rocking the shaft'60 against the action of the spring 65 7 5 In the construction herein shown, the cam 61 is pivotally secured-at itsupper end to the bracket 62 by a .pin Z0. The lower'end of the cam (51 is formed to provide an inclined cam surface 71 which is arranged to engage the roller 69 upon the down stroke of the head 5 for rockingthe shaft'in a co'im ter clockwise direction. The cam 61 is held in its effective position on its down stroke by a stop pin 72 mounted on the bracket 62, and against which the cam is resiliently urged by a spring 73. One end of the spring 73 is connected to the cam' 61, and the other end thereof is connected to a pin 74 mounted on the head 5 ()n the down stroke of the head 5. when the cam surface 71 passes the roller normal position (shown in,.l igure 7) under the action of the spring 65, and then, upon the up stroke of the head 5, the upper face 'of the cam 9 part 'i'l-rides on the roller 69 soas to-force the cam 61 outwardly away from the stop 72. as shown in dotted outline in Figure 7. On the up stroke of the head 5, after the cam is returned to the stop pin 72 the action of the spring 73.

In operation, the selected punch 4 is locked to the head5 by the-insertion of the respective key29. The punches or the key seats are numbered to facilitate the selection. 7 While the cards are being fed in a step-hy-step movement along the guideway, the head 5 'is continuously reciprocated by v the rocker arm 24 so as to move thelower no ends of the punches 4 into and out of engagement with the stencil frames 14. On the r down, stroke of the head 5, those punches which are not in the selection will merely rest upon the stencil frames 14 without making any impression, while .the'selected punches Wlll continue to move downward ly to pierce the stencils under the action of the head 5.. Upon the down stroke of the head 5, the cam 61 moves downwardly into engagement with the roller 69 and rocks the shaft 60 in a counter clockwise directionso as to actuate the fingers46. The fingers 46 thereby move into engagement with two adjacent stencils so as to urge said stencils transversely against the guideblock, lland forwardly against the stop shoulders 42, where they are momentarily held in a precise position o the guideway 2 for engage- ,roller 69, the
