WEB-PUNCHING MECHANISIMI.

Applioationiled February 19, 1923. Serial No. 620,116..

To all fwkomiz't may concern Be it known that I, GEORGE W. SWIFT, J r., a citizen of the United States, and resident or Bordentown, county of Burlington, and

5 State of New Jersey, have invented certain new and useful Improvements in Web- Punching Mechanisms, of which the following is a specification. i

. The present invention relates to an improved mechanism forv punching or other- Wise marking a succession of printed forms upon'a traveling web. The improved mechanism may be used for producing anyl desired successiveimpressions u on a web or series of sheets, but is particu arly applicable for punching holes at the desired intervals in a traveling web.

The improved punching or marking mechanism comprises a pair of oscillatory shafts mounted in parallel relation and having means acting through one shaft for imparting a to and fro oscillating motion and means acting through the other shaft for causing intermittent bodily movemnt of one shaft toward and away from the other. The relatively movable oscillatory shafts carry `either one or both printing, punching or other marking devices for acting upon a web or sheets that pass between the shafts. The devices-for oscillating the shaft and for bodily moving one shaft toward and away from the other are preferably actuated from the common drive, which is operated at a proportional speed with relation to the feed of the web -or sheets. This proportional Speed will differ for different ,form lengths which are operated upon and for the ready adjustment of the speed of operation of the punching or numbering shafts with relation to the feed of the web I provide a changeable proportional gear mechanism of any suitable form.v The shaft oscillating devices are adjustable independently of their driving mechanism to accurately adjust the speed of oscillation to the surface speed of the web or sheets, without regard to the adjusted periodic bodily movement of the shaft.

More specifically the 'preferred embodiment of the improved machine includes an f oscillatory shaft mounted in fixed bearings, a companion shaft mounted in adjustable and the main drive shaft of the machine l from which the web or sheeets are driven..

In order that the invention may be fully understood it will first be described with reference to the accompanying drawings and afterwards pointed out more particularly in the annexed claims.

In said drawings: y M

Fig. 1 is a detail lan view of a section of a web machine to w ich the improved mechanism in the form of a multiple web punch is applied, this view being taken in the direction of the arrow 1 of Fig. 2.

Fig. 2 is a detail side elevation of the same mechanism.

Figs. 3 and 4 are detail sectional views taken on the lines 3 3 and 4 4 of Fig. 2.

Figs. 5, 6 and 7 are detail sectional views taken respectively on the lines 5 5, 6 6 and 7 7 of Fig. 1.

Figs. 8, 9, 10 and 11 are diagrammatic views illustrating the operation of the improved punching mechanism.

The improved mechanism is shown as part of almachine arranged to print, punch and number forms or bills upon a traveling web or succession of'sheets of paper. The embodiment of the present invention is a web punching mechanism arranged to punch the desired holes in the proper location in the printed forms of a traveling web.

1 and 2 are the side frames of the machine. 10 is a transverse shaft journalled in fixed bearings in the side frames 1, 2 and carrying between its ends a number of adjustably mounted punch members 11. 15 is The eccentric bushings 16 `are journalled in suitable bearings in the side frames 1 and 2 so that in their rotation they will cause the shaft V15 to move bodily toward and away from the shaft 10. l

indicates a webor series of sheets of paper passing between guide rolls 21 and up between the shafts `10 and 15 in the plane in which the punch and die members operateb for punching openings in the passing we Shaft 10 has adjustably secured to its projecting end a crank arm 25 mounted upon a Split collar 26 by which itis attached to shaft 10. A pitman 28 connects crank pin 25 with a crank pin 30 formed upon a disk 31 adj ustably mounted in an eccentric recess 32 by means of set screws 33. A disk 35 is mounted upon the projecting end of a shaft freely journalled in the side frame 1 and carrying at its opposite end a beveled gear 41 meshing with and driven by a similar gear 42, which is adjustablv secured to a driving shaft 50 by means of a splined hub 43 and set screws 44. By loosening the screws 44 the gear 42 can be adjusted around shaft 50 and afterwards securely fastened in the desired adjusted position.

gear 65 is in constant mesh with a similar ring gear 70 adjustably mounted upon a flanged bearing bushing 75 by means of flanged set screws 71. The bushin 75 is freely journalled in one of the side rames and is splined or keyed as indicated at 76 to the end of a transverse shaft 80 carryinor at one end a beveled gear 85 meshing with a similar gear 86 adjustably mounted upon shaft 50 by means of a splined collar 87 and set screws The specific description of geared busliings 16 and 76 is with reference to one end only of the shafts 15 and 80, but it should be understood that thesame arrangement of geared bushings is also provided at the opposite end of these shafts so that the rotation of bushings 16 at opposite ends of shaft 15 will cause an even bodily movement of shaft 15 toward and away from shaft 10.

The common drive shaft 50 is suitably journalled in horizontal position upon the side frame 2 by means of bearing brackets 90. This shaft 50 must be driven by suitable gearing from the main drive shaft ot' the machine. The speed of shaft 50 must have a proper proportional relation to the surface speed of the web to be operated circumferentiall upon. This proportional speed will dier with different length forms that have been printed upon the web, since the periodic bodily movement of shaft 15 toward shaft.

10 determines the number of punching operations upon the web. In Fig. 1 is shown more or less diagrammatically a gear 95 upon shaft 50 driven through intermediate gear 96 upon a stud shaft that is adjustable of gear 95 and a ear 97 upon the mainl riving shaft 100. T e gear 95 is made removable and chan eable so that by mounting the proper size o gear 97 upon shaft 100 the desired speed ratio between the punching operation and traveling web can be obtained.

In the operation of punching a web, it will be understood that the rotation of eccentric bushing 16 moves shaft 15 carrying the die members toward and away from shaft 10 carrying the punch members. As the punch and die members come into cooperative relation the shafts 10 and 11 are rocked by the crank and pitman device described to cause the punch and die members to travel in the same direction and at the same speed as the web 20 which is fastened between them. At the completion of each punchin operation the bushings 16 separate the sha t sufficiently to disengage the punch and die membeis for their return stroke.

It will be understood that the adjustments shown enable the operator to first determine the necessary periodic operation of the punches to suit the length of forms to be operated upon. This is accomplished by mounting the proper size of driving gear 97 upon the shaft 100. It then becomes necessary to adjust the cranks 25 and 30 to get the proper throw and speed of the crank when the punch and die members are brought into cooperative relation. These parts can be adjusted to nicety to cause the punch and die members to o erate at the exact speed of the travelin we upon which they operate. Figs. 9 an 11 show plan views of two webs with different form lengths indicated upon them, the forms of Fig. 9 being twice the length of those in Fig. 11. It will be understood that to punch the short form length of Fig. 11, it is necessary that the mechanism be adjusted to operate twice as fast as for those form lengths shown in Fig. 9, that is the number of bodily movements of shaft 15 toward shaft 10 in unching Fig. 11 form lengths must be double that required in punching Fig. 9 form lengths. This is true on the assumption that the speed of the web operated upon is the same in both cases. Figs. 8 and 10 show respectively the adjustment for these two form lengths illustrated in Figs. 9 and 11. It will be noted in Fig. 8 that the throw of the crank for oscillating the shafts 10 and 15 is greater and faster when operating upon shafts 10 and 15 is, however, the same in both cases.
