CLARENCRICHARD BUSCHMEYER, 0F DAYTON, OHIO, ASSIGNOR TO JOHN Q. SHERMAN AND WILLIAM c. SHERMAN,

BOTH OF DAYTON, OHIO.

ROTARY PUNCH.

' Toall whom t may concern:

Be it known that I, CLARENCE R; BUSCH MEYER, a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements. in Rotary Punches, of which the following' is a full, clear, and exact description, reference beinghad to the accompanyingdrawings, forming part of this specific-ation.

The object of my invention is to provide a rotary punch for punching holes in paper, cardboard, sheet metal and the likein which the punching dies shall be so mounted and operatedv that there shall be no shearing cut as the punch is operated.v

This object is attained by' mounting the coperating dies pivotally on the rotating meurber and fby means of cams with which the dies are connected maintaining' parallelism between the male and female mem` bers of the die punch between which the sheet to be treated is passed, so that the punch acts upon the sheet always at a right angle to the web or sheet under treatment and without any tendency to shear due to the rotary movement of the member uponwhichthe dies are mounted.

While my improvement is adapted for the punching of holes in a web or sheet of any material, in the particular embodiment thereof to be hereinafter pointed out and claimed, I have designed a machine especially intended for punching a uniformly spaced continuous series of holes along the side edges of strips or webs of paper designed for use in autographic registers of the sprocket wheel feed type and in which my improved punch is intended t0. 'be attached to the printingpress employed for printing. the webs of paper and to be run: continuously in connection with the printing operation.

In the drawings,

position 'of bothI crankl 1o (see Fig. 6)

Patented Mal-.16, 192e. Serial No. 195.820.

Fig. 6 is a plan View in detail of the balancing shaft upon which the dies are mounted. Y

Fig. 7 is a detail of the showing the series of holes.

e punching' mechanism is mounted in a substantial framework consisting of side standards l, 1, top 2 and lloottom 3, and when used in connection with a printing press the framework willbe press in web ofv roll 5.

In connection with the use of such strips in autographic registers, it is usual to print and perforate the paper in a wide strip and afterward to slit thc paper into the proper widths. In illustrating my invention, I have shown six sets of the punches for perforating the side edges of five strips of paper, the outside edges of the strip used being punched with a. single series of holes and the intermediate portions punched with a double series as shown in Fig. 7, and the web' afterward divided so as to form; single strips with a single series of openings along each edge. y

The construction and operation of the punching mechanism, however, of course is the same whether. only a single series of holes are to be punched, or any number that may be desired.

/Mounted horizontally in suitable journals in the side standards l, 1, ofthe framework, y one albove the other, are the shafts 6, 7,- which carry the dieunits. As illustrated in the drawings, these die units are mounted on disks S, 8, for the upper shaft, and 9, 9.l for the lower shaft, which disks are secured to their respective shafts by set screws 24. The dies are tightly mounted on shafts 10, 10, jo-urnaled in the disks 8', 8, and 9, 9, near the periphery thereof. In' the construction as illustrated in the drawings, these die units comprise the male die heads 12, 12, which are secured by set screws 13, 13, to their respective shafts. These heads carry the male cutting punches 14, 14, of which four are provided irL the embodiment illlustratedi, spaced equal distances apart. These male dies cooperate withthe female die plates 15, which are correspondingly mounted ontheir respective shafts 10, and held 'byset screws 16. Each of the 'shafts is'provided at its end on the web of paper attached to the the die units in exact outside of the unit, I provide eight ofthedisk plates with crank arms 17, 18, extending in opposite directions and carrying they studs 19, in cam grooves21 in the face of the fixed cams 22,l 23. The cam grooves 21 rare so formed that as the shafts 10 carrying the die units are rotated by the'shafts 6 and 7, the action of the cam grooves will maintain horizontal relation and prevent them from upsetting or tipping during` the rotation, the shafts 10 oscillating to maintain this horizontal position of the dies. One of the shafts, as 7, when the attachment is to be used with the printing press, is driven by the `gear 25 keyed to the end thereof (see Fig. l), and this gear is driven by the gear 26 from the printing ma chine drive. Of course other methods of driving the rotary punching devices may be provided. l

In order that there may be no lost motion in the driving of the upper die members. ,I prefer to drive the upper shaft G from the lower shaft through the medium of a slide bar and link connection of the kind used in steam engines. The gear 25 carries a stud 27 which is coupled by a link 28 to a slide block 29, mounted to slide horizontally in a slide guide 30, secured to the framework, and the slide lblock 29 is coupled by the link 31 to the crank arm 32 secured on the outer end of the shaft 6. i

On the opposite sideof the machine. the shaft 7 is provided with a crank arm which is coupled by a link '33 with a corresponding slide block 34, mounted to slide horizontally in the slide guide 35,- and the slideV block lis also coupled by the link 36 with the crank 'arm 37 mounted on the and link connections for the opposite ends of the two shafts 6 and 7 are set with the crank arms pivoted approximately fortyfive degrees apart with reference to the axes of the shafts, or in other words, set on the quarter, so that there is ne-ver any dead center and lost motion is thereby avoided, and the rotary members carrying` the die units can be operated with great accuracy.

While I have not illustrated it in the drawings, ball bearings will be provided for the various crank arms where wear is anticipated.

In the embodiment of my invention in which webs of'paper for use in autographic registers are tobe perforated with holes along the side edges, it is essential 'that the holes shall be uniformly space d. therefore provided four die punches and arranged the die units so that the punching operations-shall follow in succession and the distances between the holes shall be exactly uniform. With the construction illustrated, in order to obtain the series of holes as shown in Fig. 7, with four punches in each u nlts for each spaced forty-five degrees apart. 20. These studs ride shaft 6. The slide I have rotary member, and these eight units are Of course with three or two punches in each unit, a different spacing would have to be provided for the units.

The construction and operation of the machine will be obvious from the foregoing description. The web of paper l is run between the rotary members, and the shaft 7 driven in anysuitable way, which in turn as described drives the shaft 6, andthe male and female dieyheads are brought together without any shearing cut by reasonv of the action of the cam grooves on the ends of the die unit shafts. Each ofthe male die units is provided with a stripper plate 38, mount-f ed on pms 39, 39, with coiled springs 40 to ca-use the plate to strip the paper from the punches as the male die leaves the female die.

It will of course lbe understood that/.as many sets of dies may be various shafts as desired, and that the die units may be so spaced as to punch the holes in any desired relation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, sz-
