In these drawings, I have illustrated one embodiment of my invention. It will be understood, however, that this particular structure is merely illustrative, and that the structure by which the objects of my invention may be carried out is susk ceptible of modification and variation within wide limits. For instance, either one or a great number of cooperating punch and die units may be used; they may be used to perforate paper sheets or webs, either before or after the webs have been printed, or to perforate Webs which are intended for use, unprinted. The perforations may be carried out simultaneously with thel printing of the webs or as a separate operation in either one assembly comprising a pair of punch-anddie holder shafts rand supported parts or a plurality thereof may be used to produce perforations of widely varying sizes and location in sheets oi widely divergent dimensions.`

As here illustrated, the attachment comprises a pair of parallel spaced shafts I and 2 mounted in any-suitable frame, not-shown, which shafts have non-rotatably and axially adjustably mountedv -thereon annular punch and die reels 3 and 4 respectively, which carry, respectively, punch and die holders 5 and 6. The shafts are synchronized with one another to rotate in opposite directions at the same speed, whereby the punch 'I mounted in the punch holder 5 cooperates with the die 8 mounted in the die holder I to punch an aperture 50 in a paper sheet or web l'49 passing therebetween, as shown in Figure 3. The paper disk 5I punched from the aperture 50 is received in the enlargedvbo-re I2 of the die Il, from wluch it falls during the travel of the die holder about the shaft 2 in operation.

The shafts I and 2 are preferably synchronized with the form-printing roller of a printing press, to which the supporting frame, not shown, is adapted to be attached; and upon rotation of the form-printing roller in operation, the shafts I and 2 will be suitably rotated in opposite directions at the same speed.

Y'I'he punch reel 3, which is non-rotatably mounted :on the shaft I and axially adjustable with respect thereto, has an annular radially disposed channel I3 in the periphery thereof, which channel has an undercut groove I3a extending axially from one side thereof at the bottom of the channel. Mounted in this channel I3 is a plurality of substantially L-section punch-holders 5 having a projection 5a, adapted to snugly engage in the groove I 3a of the channel, each of which punch-holders V5 is securely 'locked in the channel I3 by a wedge 9 and set screw I4, which is threaded in the axial bore I5 extending from one side face ofthe punch reel 3. As shown in Figure 10, a substantial number of these set screws I4 are annularly disposed about the side face of the punch reel 3. 'Ihe cooperation of the portion 5a of the punch-holder 5 and groove I3a of the channel I3 prevents radial movement of the punch-holder 5 with respect to the punch reel 3, and provision is also made to prevent relative movement between the punch-holder and punch reel annularly.

This last-named means comprises a plurality of annularly-arranged axial grooves I6 which are spaced at a slight distance from one another t extend axially of the periphery of the punch reel 3. Projecting from the lower face of the punch member I is an axially-disposed projection I'I, which is adapted to cooperate with any desired one of the grooves I6 to prevent annular relative movement between the punch reel 3 and the punch holder 5. The punch member 'I is held in locked engagement in the punch holder by the set screw Via, which cooperates with the annular groove la of the punch member '1, as

iown in Figure 5. As shown in Figures 4 and 5, the punch holder 5 is of arcuate cross section, whereby to provide for a close fit between it and the complementary grooved portion of the punch reel 3. Adjacent one side face of the punch reel 3 is the annular surface I8 which is graduated to provide a scale, as shown in Figure 2, which cooperates with the arrow I9 on the punch reel 3 to denitely locate or position the punch holder 5 with respect to the punch reel.

Non-rotatably mounted on the shaft 2 for axial adjustment with respect thereto is the die reel 4 having therein the annularly-disposedv channel 23, which is similar to the channel I3 in thepunch reel 3. This channel has extending from one sidewall thereof the undercut groove 23a which is similar to the groove I 3a of the channel I3, which cooperates with the projection 5a on the die holder 5, which projection is similar to the projection 5a on the punch holder 5. The die holder 6 is of similar conguration to the punch holder 5 and-is secured in the channel 23 in the same manner as the punch holder 5 is secured in the channel I3 by means of the wedge I and set screw 24. The wedge I0 is identical with the wedge 9, and the set screw 24 is identical with the set screw I4, described above. The die member 8 is of annular configuration and has its forward end beveled at 8a and has a bore 8b extending from the forward end into the enlarged bore dening the portion I2. At one side of the die member 8 is a stepped portion 25, which cooperates with a screw 26 to secure the die member 8 against the shoulder 6c of the bore 5b in the die holder 6. Secured in the die holder 3, parallel to and axially spaced from the screw 26, is the pin 21 which is adapted to cooperate with the grooves 28 in the die holder 4 in the same manner as the projection I 'I cooperates with the grooves I6 of the punch reel to prevent relative movement between the die holder 6 and the die reel 4. The grooves 28,0f the die reel 4 are similar to the grooves I6 in the punch reel 3 `and are disposed on the die reel 4 in the same manner as the grooves I6 are disposed on the punch reel 3. SeeFigures 1, 3, 6 and '7. Disposed adjacent one side of the die reel 4 is the annular surface 29, which is graduated in the same manner as is the surface I8 of the punch reel 3 to provide for easy and accurate adjustment of the ,die reel holder 4 by cooperation with the arrow SII onthe die holder 6. i

It is to be understood that the locating grooves I6 and 26 for the punch and die holders respectively, as well as the scales therefor, may be located at the sides of the respective reels 3 and 4 instead of on the peripheries thereof and the projection I'I and pin 2'! may be suitably located for cooperation therewith, and a suitably located pin may be substituted for the projection II for cooperation with the locating grooves.

It is to be understood that a plurality of die holders and cooperating punch holders is to be used, which are to be spaced about the peripheries of the die reel 4 and punch reel 3 to cooperate one with the other, as shown particularly in Figures 9, 10 and 11. The punch reel 3 and die reel 4 may be secured on the respective shafts I and 2 by means of a spline or key, such as Ia, 2a, shown in Figures 9 and 10, or any other suitable means and may be secured in adjusted axial position with respect to the shafts by means of any suitable means, such as set screws or the like, not shown. The shafts I and 2 may be mounted in the frame, not shown, in suitable bearings which may be adjustable, if desired, and the frame also, which is not shown, may be of any suitable type and may be adjustable withrespect to the printing press or drive means, from which the shafts are driven, if desired.

Operation In preparing the device for operation, the shafts are synchronized, preferably so that the Zero marks of the scales I8 and 29, shown diagrammatically in Figure 14, are opposite one another so that, when the respective punch holders 5 and die holders 6 are set at corresponding distances therefrom by bringing the arrows Ill and 30 respectively opposite the desired scale markings on the scales I8 and 29 respectively, as shown in Figures 1 and 2, the punches 'I and dies 8 will cooperate, as shown in Figures 9 and 10. If it is desired to punch more than one series of holes or apertures in the paper web or' sheet, as shown, for instance, in Figures 20 and 21, two or more punch reels 3 are spacedly mounted on `the shaft I, and two or more die reels 4 are mounted on the shaft 2 in adjustment with one another, as shown in Figure 15.

In orderto secure proper spacing of the punch holders and cooperating die holders axially of the shafts I and 2, the measuring or gauge bar 46 is used. This measuring or gauge bar 4l) comprises a flat plate having at either end identical members 4I spaced from one another a definite distance. These members 4I comprise stepped annular members, which define coaxial superposed cylindrical portions a, b, c and d, the diarneters of which correspond. respectively with the respective diameters of the bore I'I in the punch member 'I and the bores 8b in the respecthe bore TI in the punch member 'I is designated in Figure 16 as a.

As shown in Figure 15, when the measuring or gauge bar 40 is used to space the die members, that part of each member 4I, which is designated a, ts into the bore 'I'I of the die member "I, and the positions of the measuring or gauge bar 40, when used to space the die holders, vis illustrated as used on dies of the three sizes shown in Figure 16 respectively in Figures 17, 18 and 19. It is to be understood that punch members of suitable dimensions are to be used with each of the die members 8, illustrated in Figure 16, and that the applicant has disclosed only a few of the many sizes of die members, which may be used in his device.

With reference to Figures 15, 16, 20 and 21 particularly, it will be noted that the dimension between the aperture centers in one direction is designated W, which corresponds to the distance between the centers of the punch members 'I and also the distance between the centers of the members 4I of the measuring or gauge bar 40, which is used to secure proper spacing of the punch reels and die reels with respect one to another. It will thus be seen that this dimension may be changed at will by the use of a measuring `or gauge bar, having the desired dimension W. It will also be noted that the spacing of the respective holes 56 in series, as shown in Figures 20 and 21, .is designated L, and l and L respectively, which dimensions correspond with `the linear spacing of the respective punch holders and die holders with respect to the graduated scales I8 and 23 respectively, as is shown, for instance, in Figures 9, 10, 12 and 13. It will thus beseen that the applicant may change the dimensions Z and L, as well as the dimension W at will, the

\ adjustment of the dimensions l and L being accomplished by the adjustment of the punch holders 5 and die holders 6 in the respective channels I3 and 23 respectively, and the adjustment of the dimension W being accomplished by the use of a suitable measuring or gauge bar 4i) having a predetermined dimension W.
