MACHINE FOR EFFECTING SLOTS IN CARDS FOR STATISTIG OR SIMILAR PURPOSES.

Application filed July 16, 1919.

To all whom it may concern:

. Be it known that I, KARL Earn, LEONARD LTEDSTRAXD, a subject of the King of Sweden, residing at 9 Volmar Yxkullsgatan, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Machines for Effeeting Slots in cards for Statistic or Similar Purposes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a. machine for effecting slots in cards for statistic or similar purposes, for instance slots of the type stated in the U. S. Letters Patent Nos. 1,261.413, 1,334,957, and U. S. application, Serial No. 311,389, and is described in the following specification adapted for effecting such slots in the cards as are shown in Fig. 1 of the Letters Patent No. 1,334,957.

Fig. 1 in the accompanying drawings shows in a plan view and as an example a machine arranged in accordance with this invention. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1; the carriage together with the dies being omitted. Figs. 4 and 5 show in a side view and a plan view respectively a carriage supporting the card. Figs. 6 and 7 show in a side View and a plan view respectively a movable die together with the matrix and means for moving the same. Figs. S and 9 show in a side view and a plan view respectively a further modification of the die and the matrix.

The machine has a carriage l-consisting of a frame and movable on rollers 2, journalled in the frame work 3 of the machine. A frame 5 is pivoted at 4 to the said carriage and between the said frame and the carriage the card is mount'ed,.in which slots are tobe provided. The frame 5 is held in its dropped position by two catches 7, movable on the carriage and acted upon by springs 6 respectively. As the said catches are disengaged, which is effected automatically in the manner stated below, the frame 5 is swung upward to the position indicated by dot-ted lines in Fig. 4 by springs 8, fixed to the carriage and connected with the frame 5 in any suitable manner, so that the card may be taken out. The lower side of the bottom part of the carriage is provided with teeth meshing with toothed wheels 9 on a rotatable shaft 11 mounted in bearings 10, Fig. 2. The said shaft is provided with a pinion 12 Serial No. 311,390.

meshing with a pinion 13 on a shaft 14, which at one of its ends has a clutch member 15, which is conical inside and slidable on the shaft but is caused to rotate with the same by a pin and slot connection 16. The

said member 15 may be shifted by a lever not shown, which tends partly to normally keep the lever arm in engagement with a notch 21, provided in a rod 22, which is slidably mounted in the frame of the machine and provided with a handle or button, partly to move the part 15 toward the right, Fig. 2. By moving manually the said rod 22 toward the left the clutch member 15 is brought into engagement with a conical clutch member 23 provided on a shaft 24, which by means of gearings 25, 26, 27, 28 29 is rotated by a shaft 30, connected for instance with an electrio motor (not shown), so that the said member 23 is rotated continuously while the machinev is used. The clutch 15, 23 is normally in disengaged position.

As the carriage 1 is in the position shown in Fig. 3, the card is, placed on the same and the frame 5 is dropped and locked. For moving the carriage 1 toward the left, Figs. 1 and 3. and placing the card under the device of the machine providing the cards with slots, a cord fixed to the carriage may be used, Which cord passes round a roller and is provided with a weight, or a spiral spring may be used, which actuates a. shaft, provided with toothed wheels, meshing with the teeth of the carriage, or any other suitable means may be used. The carriage 1 is held in the position shown in Fig. 3 by two catches 31, engaging projections 32 provided on the carriage. The said catches 31 are disengaged by means of a rod 32, slida'bly mounted in the frame of the machlne and actuated manually. On the rod 32 cam pieces 33 are provided, which, as the rod is moved in one direction, force the catches 31 outof engagement with the carriage. The latter is then moved toward the left, Fig. 3, until two projections 34, provided on the carriage 1, strike a second carriage 35, sl1dably mounted on the carriagel The said carriage35 is provided on its top side with teeth, engaging toothed wheels 36 on a shaft 37 journalled in the frame of the machine. On the shaft 37 an escapenient wheel 38 is fixed, co-operating with a double pawl 39, 40, swingable on a pin 41. From the said pawl an arm 43 extends, which is acted upon by a spring 42 and by a link 44 is connected with a lever 46 pivoted at 45. A manually actuated key plate 49 is fixed to arms 4'? swing able on a shaft 48. One of the said arms 47 is connected with the lever 46 by means of a'pin 50, so that, by depressing the key plate 49 the lever 46 is swung on the pin and shifts the pawl 39,40 against the action of the spring- 42. In this manner the escapement wheel 38 is permitted to rotate one step in the direction indicated by the arrow, a'ctuated'by the carriage 1 and the carriage '35. Consequently, each time the lrey plate 49 is depressed, the carriage 1 will be moved onestep towargd-theleft, Fig; 3 and Fig 1 viewed in the direction of the arrow, so that the sections of the cards, which are to be provided with slots, may be brought suoces sively into position below'the dies respectively. Instead of the escap ement shown in the drawings any escapement of known or suitable construction may be used. As the card has been provided with the desired slots and the carriage together "with the card is to be brought back to" its starting position, the clutch '15, 23 is engaged by pushing the rod 22 inwards. The toothed wheels 9 then at'first move the carriage 1 alone toward the right, until two projections 51' provided on the same strike the carriage 35 and bring the same with themselves. The said carriages are then moved simultaneously toward the right. As the carriages reach the position shown in Fig. 3, a projection on the carriage 1 strikes a two-armed lever 53, pivoted at 52, which is thus swung and moves the lever arm 17 out of engagement with the notch 21 of the rod 22, so that the lever arm 17, acted upon by .its spring disengages the clutch member 15 fromthe member 23 and the carriages 1 and 35 are brought to astandstill. Ii'nmediately before therarriages come to a standstill, two spring actuated pawls 52 pivoted to the frame of the machine engage projections on the catches 7, and disengage the same, so that the frame 5 is swung upward'by the springs 8 and the card may be removed. In order that the pawl 39, 40, during the return movement of the carriages to th'e starting position, may not prevent the escapem ent wheel from rotating in a direction "opposite to that indicated by the arrow, the pawl 40 is pivoted to the pawl 39 and is held by a spring '54 against an abutment 55 provided 'on the same. The machine may, evldently, be so arranged, that the carriage 1. may be returned manually (by means of a hand lever or the like) to the position, in

which the card is placed on the'same.

For providing the cards with slots of the type shown in Fig. 1 of the Letters Patent No. 1,334,957,the machine is provided with an apparatus fully described in the said Letters Patent. The dies consist of arms, swingably mounted on shafts 58, 59 respectively fixed to end pieces 60 of a carriage 61, which is movable in guides provided in thefram'e of the machine. In Fig. 1 only the one set of dies is shown. In the said end pieces 60 rods 62 are fixed, with which and the dies respectively springs 63 are connected, which hold the dies respee tively in raised or inoperative position. The carriage 61 is provided with slots 64, one for each die, so that the carriage forms the nee-- essary matrixf The said carriage may be moved toward the left and toward the right, Fig. 1, viewed in the direction of the arrow for placing the necessary pair of dies under a hammer described blow, which actuates the dies and causes the same to cut a pair of slots in the card. For the moving -ofthe carriage 61 teeth 65 areprovided on its lower side, which are engaged by toothed segments 66, fixed toa shaft 67 journalled in the frame of the machine. To the said shaft a third toothed segment 68 is fixed, meshing with a toothed segment 69, pivoted at 70. An arm 71, provided with a handle 72, is jointed to the segment 69. Conse quently by swinging the arm 71 the carriage 61 together with the dies is moved. In the fore part of the frame of the machine notches 73 are provided, into which the arm 71 may be placed for fixing the osition of the same. At the said notches 'gures are provided, indicating which pair of dies is ltH) located under the hammer. By moving the carriage 61 any pair of dies may be located under a hammer 7 4, which is fixed to a shaft 7 5, journalled in the frame of the machine and movable longitudinally. The said hammer is normally held in raised position by a below the eccentric and, after the hammer has operated, automatically return the same to its position at the side of the e ccentric, the machine is provided with a device, which now will be described.

From a shaft 80, journalled in the frame of the machine, two arms 81 extend which carry a key plate 82,a.dapted to be operated manually. As the said plate 82 is depressed. a lever arm 83 is actuated, which is pivoted at 84. The said lever arm 83 is by means of a link 85 connected with a bell crank 87, pivoted at 86 and by a pin and slot joint connected with a swingable arm 89 pivoted at 88. The said arm 89 is connected with a washer 91, slidably mounted on the shaft 75. Between the said washer 91 and a flange 92 on the shaft 75 a coil-spring 93 is located, which as the arm 89 and the washer are shifted by means of the key plate 82, is compressed to such a degree, that its tension is greaterthan the tension of a second coilspring. 94, provided on the shaft 75 and bearing against the frame of the machine and a flange 95 on the shaft 75. The arm 89 is held in shifted position by a catch 97, pivoted at 96, as shown in Figs. 1 and 3. As the tension of the spring 93 is increased, the spring moves the shaft 75 toward the left, so that the hammer 74 is forced against the right hand side of'the eccentric 77, Fig. 1, and, as the eccentric arrives to its upper position, the shaft 75 together with the ham-. mer 74 are moved for a further distance, so that the hammer is located right under the eccentric. The latter position of the hammer is fixed by a flange 77 provided on the eccentric. The rotating eccentric forces the hammer against the pair of dies, which for the present is located under the eccentric so that the said dies effect two slots in the card. During the working stroke of the hammer an adjustable screw 98 in screw-threaded engagement with a finger 99 on the hammer strikes the rear arm of the catch 97 and forces the catch out of engagement with arm 89, which results in the tension of the spring 93 being decreased and the spring 94 forcing the shaft 75 and the hammer 74 toward the right, as soon as the eccentric arrives to its upper position. Consequently, the ham mer is automatically returned to the position, in which it is out of the path of the eccentric and effects only one blow at a time. As the arm 71, by means of which the car riage 61 together withthe dies is shifted, is depressed into the notches 73 respectively, it actuates the key-plate 82 by means of a pin 100 provided'for instance on'the handle 72, so that the tension of the spring 93 is in creased in the manner described above without any special manipulation. The machine may be so arranged, that the arm 71 actuates also the keyplate '49 for the shifting of the carriage of the dies. The machine shown in spects without departing from the scope of the invention. For instance the card may be stationary and the hammer together with its actuating mechanism and the carriage supporting the dies may be provided on a second carriage, so that not only the dies may be located under the hammer asstated above but the dies together, with the hammerand its actuating mechanism may be shifted with relation to the card, and the dies, which should operate, may be placed above the section of the card, in which slots'are'to'be effected. I

In Fig. 2 of the Letters-Patent No. 1,334, 957 slots are shown, the innerend of which coincide, so that each pair of slots formsa single slot. In order that the machine may be able to effect slots of the said type. in the cards, it may be provided with a single die with a corresponding matrix, in which case a relative movement of the saiddie and the card and longitudinally of the die and thus in respect to an imaginary plane in the machine is effected so that the total length of the parts of the die located at opposite sides of the said plane in each position of the die relatively to the card is unvariable; Preferably, the die and the matrix are movable. longitudinally, as shown in Figs. '6 and 7. In the said figures 110 designates the matrix. The said matrix is movable in a guide 111 and is connected, for instance by means of a wire 112 of steel or metal, passing round a guide roller 113, with an arm 1.1.5, which is swingable round a pin .114 and corresponds to the arm 71, mentioned above. The said arm 115 may be shifted along a. scale 116 provided on the frame of the machine. By swinging the arm .15 the matrix 110 is moved against the action of aweight 117, adapted to move the matrix in opposite direction. 'An arm 118 is pivoted to the matrix and carries the die 119. 74 is the hammer actuating the die. The actuating mechanism of the said hflIIliTlGI may be ar ranged in the same man'ner as stated above. By shifting the matrix and the hammer the" slot may be provided in the desired part of the sections respectively of the card.

Also slots, which extend inward from two parallel lines and the total length of which is unvariable may be effected by means of a by springs (not shown) single die and a matrix belonging to the same, if the parts are arranged as shown in Figs. .8 and-9. Cards provided with such slots may be sorted by sticks or the like threaded through the same and moved to' ward one another. In the said figures the die 120 and the matrix 121 are stationary. In the matrix 121 a movable piece 122 is provided, which divides the matrix into two parts. The die 120 consistso't a plurality of laminae (eight in the shown example), which preferably have the same size and are movable toward and from the matrix insuitable guides (not shown). The said laminae are held in the normal position shown in Fig. 8 or the like. Above the die a rod 123 is movably mounted, which extends along the die andbesides is movable toward and from the same. 123 may bebrought by the hammer 74 to actuate the die. In the said rod 123. a notch 124Jis provided, which is located right above the piece 122 and is somewhat longer than the laminae respectively. The piece 122 and the rod 123 may be moved for instance in the same manner as the matrix 110 and the die 119 in Figs. 6 and and brought on a line with any one of the laminm of the die 120. As the rod 123 is forced against the die 120 by the hammer 74:, one of the laminae is inactive viz. the lamina which is located right below the notch 124i. Consequently, it

the piece 122 and the rod 123 have the position shown in Fig. 8, two slots are effected in the card, as the hammer 74- is lowered. The length of one of the said slots corresponds to the length of the lamina, while the length of the other slot corresponds to the total length of six laminae. If thepiece 122 and the rod 123are moved into another position,

slots are provided having another length- In each case, however, the total length of the slotsis unvariable. Instead of the rod 128 and the piece 122 being movable, they may be-sta-tionary in which case the die and the matrix together with-the card are movable.

It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing m invention; and hence I do not intend to be limited to the details herein shown and described, except as they may be included in the claims.
