This invention relates to punching mechanism for perforating statistical records.

The object of the present invention is to pro- I vide a group of punching mechanism elements of a compact form adapted to be driven by a group of driven elements on a'machine having such elements, possibly the indicating wheels of a device having such indicating wheels, the group of punching mechanism elements being adapted to be initially incorporated into the machine having the driven elements. I

Another object of the present invention is to provide a group of punching mechanism elements of compact form and of substantially uniform width adapted to be added later as an attached sub-unit to a machine having a group of driven elements.

One way of carrying out the present invention I is illustrated by way of example in the accompanying drawings as applied to a calculating machine which has been fully described and illustrated in my pending U. S. patent application Serial No. 144,022, filed May 21, 1937.

As above mentioned the construction and operation per se of the calculating machine shown in Figures 1 and 2 has been fully described in my pending patent application Serial No. 144,022, and only a brief description will now be given in order that the operation of the punching mechanism may be understood.

The calculatingmachine comprises a plurality of result screens8 and a scanning cylinder 9 fixedly mounted on a shaft Ill adapted to be rotated from the drive of the calculating machine through gearing. The scanning cylinder 9 cooperates with a result screen 8 to control through a photo-electric cell mounted in the interior of the scanning cylinder 9 (and consequently not shown) the setting of eight typewheels 4, one type-wheel being provided for each column or denomination of the result, said wheels being provided with types or numerals II. The means for operating the type-wheels comprises a group of eight discs l2, (Figure 2) fixed to rotate with the shaft I0 each disc being formed with a gear element l3. The gear elements l3 are circumferentially displaced relatively to one another and are adapted to drive, respectively, one of a group of eight bushes l4, each of which has a toothed flange l9 adapted to be engaged by a corresponding gear element l3. It will be evident that the bushes I4 are driven successively by the respective gear elements l3. The bushes [4 are loosely mounted side .by side on a shaft 20 and are arranged to be coupled by clutches 2| to pinions 22 loosely mounted on the shaft 20. The pinions 22 mesh respectively with pinions 23 (Figures 3 and 1) rigidly connected to the type-wheels 4. Each clutch 2| is separately operated by a clutch fork 24, controlled by an armature 25, all the armatures being commonly ,controlled by a relay 26 actuated by the photoelectric cell above referred to. The arrangement is such that the pinions 22 are driven for varying periods by the respective clutches 2 l the duration of the drive in each case being controlled by, the relay 26, in order to bring the eight type-wheels into set positions in which the result of a calculating operation can be printed on a web of paper 27 drawn from supply drum- 28. To this end two eccentrics 29 are mounted at each end of the shaft 30 on which the type-wheels 4 are mounted, and these eccentrics are connected to pitmans 3| adapted to reciprocate in guide slots 32 and carrying between them a bracket '33 furnished with a printing pad 39. The arrangement is such that on the termination of a calculating operation the shaft 30 is rotated and the eccentrics 29 cause the printing pad 39 to press the paper 21 against the type-wheels 4 to obtain aprinted record of the result of the calculation. As shown in-Figure l the calculating machine is also provided with accumulator wheels 34 adapted to be driven respectively by gear wheels 35 driven by the gears 23.

The present invention is concerned with punchheld together by rivets 42. Each disc is provided on its periphery with a finger like projection 43 the projections on the various discs being circumferentially displaced so that in general they follow a helical course around the periphery of the group as best seen in Figure 7 which is an elevation of a group of punches. These projections 43 constitute, and will be referred to hereafter as, the punches, and the axial position of each punch in the helix permits it to be identified with one digit value carried on type-wheel with which the group of punches is associated. Each group of discs 4| is mounted tightly on a bush 44 formed at one end with a gearwheel 45, the bushes being loosely mounted side by side on a shaft 46. A direct coupling is provided between each type-wheel 4 and its associated group of punches by means of gearing comprising one of eight gear Wheels 41 formed with hubs 48 mounted on shaft 49 and in mesh respectively with the gears 23, a gear wheel 50 mounted on a hub 48 and fixed to the gear 41, two gear sectors 5|, 52, the hubs 53, 54 of which are mounted on the shaft 5 and pinned together by pins 56. The gear sector 5| is adapted to be driven by the gear wheel 56 and the gear sector 52 is adapted to drive the gear wheel 45 rigid on a group of punches. The hubs 48 of the gear wheels 41, the hubs 53, 54 of the sectors 5|, 52, and the bushes 44 of the groups of punches act respectively as distance pieces to maintain the correct alignment of the elements with which they are associated.

The elements of the punching mechanism and drive thereto above described are mounted between side plates 5'l, 58 connected respectively to the side plates 59, 60 of the calculating machine by means such as screws 6|, and dowel pins 62, the shafts 46, 49, 55 being supported in the side plates 51, 58.

A die-plate 63 provided with a number of transverse die holes 64 equal to the number of punches extends transversely below the punches and is mounted at its ends in horizontal slots 65, 66 in the side plates 58, 51 so as to be movable horizontally within the limits of the said slots.

Means for moving the die-plate 63 in the slots 65, 66 comprises eccentrics 61, 68 fixed to the ends of the shaft 46, these eccentrics being engaged by pitmans 69, I0 carrying the die-plate 63.

A web of paper H or other material suitable for the record blank, drawn from reel 12 on shaft I2 is passed by two pairs of feed rollers 13, 13 on shaft 16 and 14, 14 on shaft 14 (Figures 3 and 6) between the groups of punch carriers 4| and the die-plate 63 and wound up on a draw-off reel 15. The rollers 13, 13 are fixed to a shaft 16 adapted to be driven from the shaft 46 through a unidirectional device c'omprisinga pinion 11 (Figures 3 and 5) splined to the shaft 46, a gear wheel 18 in mesh with the pinion 11, a pawl 19 carried on the side of the pinion 18 and a ratchet wheel8ll fixedto the shaft '16. The shaft 46 is driven through a gear train comprising gear wheels 8|, 82, and 83, from the mechanism of the calculating machine. The gear wheels 8| and B3 are splined to the shafts 30, 46 respectively, the intermediate gear wheel 82 being loosely mounted on a stub shaft 82 secured in the side plate 60. The arrangement is such that in one direction of rotation of the pinion H the pawl I9 slips over the teeth of the ratchet Wheel and does not drive it, whilst in the opposite direction of rotation the pawl 19 engages in the teeth of the ratchet wheel 80 and drives it and the shaft 76. The draw-off reel 75 is'driven through a crossed belt 84 passing over a pulley 85 fixed to the shaft I6 and a pulley 86 fixed to the shaft 81 on which the reel 15 is fixedly mounted.

In order to provide for exact registration of the punches 43 in the set positions, with the dieholes 64 in the die-plate 63, eight pawls 88 are provided one behind the other (only one of which is shown in Figure 3) each of which cooperates respectively with the pinion 45 attached to each group of punches, the pawls 88 being mounted on a shaft 89 extending parallel with the shaft 46. Each pawl is pressed by a spring 90 into contact with the teeth of the corresponding pinion 45, the springs having their free ends secured to a bar 9| extending below the punches. When the groups of punches are being driven the pawls 88 slip over the teeth of the pinions 45, but as soon as the drive to the punches ceases the pawls 88 engage immediately in the teeth of the pinions 45 and thus ensure that the punch 43 to be operated of each group registers with a die-hole 64 in the plate 63.

Figure 8 is a fragmentary plan view illustrating a punched record obtained by the punching mechanism described. Each of the undivided rectangles 92 represents an area (which of course is not delineated on the blank record) in which perforations may be made to represent values of one of the eight denominations represented respectively by the eight type-wheels 4. Only three complete areas 92 are shown in Figure 8, but it will be understood that the complete record card will contain eight such areas, one for each denomination Each rectangular area 92 may be subdivided into ten smaller areas or index points 93, each of which may be perforated to represent anyone digit of the denomination represented by the area 92. Thus, the ten index points 93 of each area 92, reading from left to right, may respectively represent the digits 0-9 of each denomination.

It is to be understood that the width of any one rectangular area 92 is equal to the width of one group of punches, and, further, that when the record blank is in position between the groups of punches 4| and the die-plate 63, the areas 92 will be in line respectively with the groups of punches, and the punches 43 of any one group will be in line respectively with the subdivided areas 93, this being effected by reason of the helical arrangement of the punches in the group.

In the record card shown perforations 94 have been made in the three complete areas 92, namely reading from left to right, in the index points 93 marked 5, 3 and 6 of the areas 92. These perforations thus represent digits 5, 3 and 6 of the three denominations represented by these areas. It will be understood that these digits of the three denominations-are those which were printed on the web 21 from the types II on the type-wheels 4 in respect of a calculation made by the machine, the punches, by reason of being in correct phase or positional relationship with the type-wheels and being directly coupled therewith so as to be driven thereby, punching the record card in places corresponding to these values.

The operation of the apparatus above described is as follows:

The type-wheels are driven through the respective discs I2, gears l3, toothed bushes l4, clutches 2| and pinions 22, 23, the extent of the drive in each case being controlled by th relay 26 operated by the mechanism of the calculating machine. In this manner the type-wheels are set so that they represent respectively the values of the various denominations of the result of a calculation. The various groups of punch carriers 4| are disposed in correct phase or positional relationship with the associated type-wheels 4 and are driven synchronously therewith through the gearing above described so that when the drive to each type-wheel is disconnected the corresponding group of punches is stopped in a position in which one of the punches 43 carried thereon, corresponding to the value on the type-wheel which will be printed, is brought into operative position relatively to the die-plate 63,the exact registration of the punch with a die-hole 64 in the die-plate being ensured by a pawl 88 as above described. Y

After one revolution of the shaft l all the type-wheels and groups of punches have been set in the required positions in which they remain. The shaft 30 is now driven by the calculating machine drive by means of the gear BI, and the shaft 46 is simultaneously driven through the gear-train 8|, 82, 83, and the eccentrics 29, 29, (on the shaft 30) and 61, 68 (on the shaft 46) operate the pitmans 3|, 3| and 69, 10. The pitmans 3I, 3| cause the printing pad 39 to press the paper 2'! on to the type-wheels to receive a printed impression of the result of the calculation, and the pitmans 69, 10 cause the die-plate 63 to approach the punches 43, the record blank being thus perforated by the set punch of each group of punches, as described, and as illustrated in Figure 8. The directions of rotation of the various gears 8I83 during the printing and punching operation are as shown by arrows in Figure 5. It will be seen that when these gears are rotating in the directions indicated, the ratchet wheel 80 is not driven, since the pawl 19 on the pinion l8 merely rides over the teeth of the ratchet wheel. The record blank TI is thus maintained stationary during the punching operations. When the printing operation has been completed the drive to the gear 8! from the calculating machine is reversed to return the printing pad 39 to the inoperative position. The rotation of the gear 83 ,is also reversed accordingly, and the die-plate 63 is returned to the inoperative position. During this restoring operation the pawl 19 drives the ratchet wheel 80 and consequently the shaft 16 and rollers 13, 13, the shaft 8'! and reel being also driven through the crossed belt 84. The web H is thus fed on to the reel 15, presenting a fresh record blank for the succeeding operation.

As illustrated in Figures 3-7, and as above described, the punching mechanism is directly pitmans 3 I, the paper web 21 and draw-off rollers therefor, and supply drum 28, all shown in Figure directly readable through a second aperture 40 coupled to the type-wheels 4 of a calculating machine. It is evident that the punching mechanism could equally well be directly coupled to other indicating or recording elements of the machine, for example, to direct reading numeral wheels, as shown in Figure 9. This figure is a view corresponding to Figure 3, the main difference being that the printing device comprising printing bracket 33 and pad 39, eccentrics 29,

in the frame of the machine. Thus the punching mechanism is directly coupled to numeral wheels giving a direct reading, instead of to typewheels adapted to print a record.

In order to avoid unnecessary repetition all such devices which give a direct reading or recording of the result of a calculation are referred to in the appended claims under the generic term indicating device.
