Fig; 4 is a section substantially oirthe,

zplane of'line 4, 4, in Fig '3, gpartsibeing omitted;

F g-' 5 is ,a fragmentarysectionalyiewsubnaled a=shaft;'2. :Said shaft may berrotazted A by pulley 30b in any desired manner. Upon i shaft2 is secureda head or-support 4: which carries the perforating or: indenting devices.

As: illustrated. the perforating or-I indenting devices comprise female dies 1 5 and imale 1 perforating or. indentingelements such as punches v6i to cooperate; therewith for punchingnorzindenting strip. or materiali7. :Tlle female dies are shown inthe form of elongated metal strips having rows ofzperforations 5?, spaced apart: according 1 to the 1 desired spacing .of:,perf0rations 7*;in strip or material 7 The. dies and punchesare shown v 7 carriedby blocks 8 for convenience of support upon hea'd .4, there being any desired, number of said: blocks 1 arranged aroundsaid headnand; detachably connectedthereto. 'I have shown theuhead 4L and blocks 8 having angular surfaces :to provide joints-,1 shown in thenature of dove-"tail jointsat :9, (Fig. 4E), wherebythe blocks may be slidably, at tached: to the head- ,and held in firm position thereon, screws lOvserving tosecurethe blocks on the head. Thefemale die plate 5 Y may be .secured along the ,periphery of blocks 8 by screws 11, (Fig. 9), whereb the dies may be removed and replaced. djacent to the outer edges of the dies the blocks 8 are shown provided with radially disposed stops or flanges 12 to engage the edges of the strips or films 7 to guide the latter in perforating or indenting position, Fig. 3.

The punches 6 are slidably carried by movable members 13 that are carried by corresponding bloolrs 8. The members 13 are shown provided with projections or jaw pieces 14 received between spaced jaws 8 on blocks 8 and pivotally supported thereon by pins or pivots 15, whereby said members are pivotally carried on the blocks to rock back and forth. I have provided two annular rows of blocks 8, six blocks in a row, each block having a pivotal member 13, arranged around head at on opposite sides thereof, whereby members 13 are arranged in opposing pairs, the members of each pair being adapted to swing toward and from each other. The number of said blocks and members may be varied, as well as the number of rows thereof. Each member 13 is preferably in segmental form adapted to be positioned radially respecting head 4: for the punching operation. In Figs. 1 and 4 part of the members 13 and punches 6 are omitted, although intended to complete the circle. The corresponding female die 5 is carried by a block 8 to cooperate with the punches 6 of the corresponding member 13. The members 13 are rocked as they are carried around with head 4 to position the punches for perforating strip 7 p and to with draw the members and punches from such position. Each member 13 is shown provided with a projection or arm 13 for operation by a cam 16 carried by frame 1 on the corresponding side. The cams 16 are shown in the form of grooves containing slidable disks or plates 17 pivotally connected with the corresponding arm 13. Said arms are shown provided with balllike ends 13 nested insockets 17 in disks 17 and retained by apertured plates 18, shown held on disks 17 by screws 19, (Figs. 3 and 4). The parts 13 17 and 18 serve in the nature of universal or ball-and-soclret joints during rotation of members 13 around shaft 2. The cams 16 are shown in the form of grooves, portions 16 of which are shown as part of frame 1, and portions 16 of which cam grooves are on plates 16 detachably carried by said frame by means of screws 20. The cam plates 16 may be removed for adjustment of parts within frame 1. To retain opposing members 13 from relative movement when in. the punching position 1 preferably provide the opposing faces of said members with cooperative projections and recesses 13, 13, (a projection on one member to enter a recess in the other member), as indicated in Big. 3, the members 13 preferably having opposing bosses 13 containing said projections and recesses, to engage in the punching position.

The punches 6 are shown slidable in radially disposed .guideways 21 in the corresponding members 13, (Figs. 2 and 6). For convenience of manufacture and for accessibility the members 13 are provided with a removable wall or plate 13 which may be secured to the main body of the member by screws. In the example illustrated the punches 6 are shown rectangular in cross section located in opposing V-like radial. grooves 21 in members 13 and corresponding plates 13 (Fig. 2), whereby the punches are guided. At their inner or operating ends the punches 6 have or are formed with one or more projections or pins 6 to cooperate with the apertures 5 of dies 5 to perforate or indent the material 7 By providing at least two projections or pins 6" on each punch 6 the main bodies of the punches may be made substantial and provide proper spacing for punching holes near the margins of conventional moving picture films. The blocks 8 are shown provided with holes 8 registering with apertures 7 of dies 7, said holes communicating with recesses 8 in said blocks, which recesses communicate with holes 2" in shaft 2 that communicate with bore 2 of said shaft, (Figs. 3 and 5). By blowing air throughbore 2 the chips or punchings from material 7 will be drawn away from dies 5 and discharged from said bore.

To move the punches toward and from dies 5 during their bodily rotation with head 4 and blocks 8 I have illustrated cam member 22, supported by frame 1 adjacent to the outer ends of the punches to cooperate with the corresponding punches. Said cam member is shown in channel or groovelike form to receive and actuate projections from the punches shown in the formof antifriction rolls 23 journaled on pivots or pins 1 24 carried at the outer ends of the punches. The cam member is shown provided with an outer surface 22 and an inner surface 22 spaced therefrom for the passage therebetween of the projections or rollers 23, said 1 I surfaces being shown concentric around the axis of shaft 2. At the entrance to the space between said surfaces is an eccentric or substantially fiat outer surface 22 which merges with curved surface 22 to engage projections or rolls 23 to cause the punches to be pushed toward the dies 5 for perforating or indenting the material 7, and at the opposite or delivery end an eccentric orsubstantially fiat inner surface 22 merges with curved surface 22 to cooperate with projections or rollers 23 to cause the punches to be withdrawn from the dies and said material. The arrangement is such that as the punches 6, which are radially outwardly positioned, are

bodilyrotated in the-direction of the arrows in Figs. 1 and, the projections 23 will suecessively engage cam surface-22 which will cause the punches to move toward the'companiondie 5 to punch-or indent the material 7 on the die, said projections remaining in the groove between surfaces 22", 22 to-retain the punches in the die, until projections 23engage cam surface 22 which will act with said projections to successively forated or indented may be received from asupply spool, in an ordinary way, (not shown), andpassed over a guide roller 26 on frame l, whence said strip passes partly around head 1 resting upon the adjacent dies 5, (Fig. 3), tobe perforated or indented. The strip passesfrom the punches toa receiving device, such as preferably over a guide roller 27 onframe 1, (Figs. 1

and 3), whence the strip passes-to a take-up spool or the-like 28 which may be operated in any desired way to wind the perforated strip.- An idle roller 29 may press against the strip 7 to cause it to-be seated snugly against dies 5, between guide stops 12, as the strip is taken up onthe rotary d1es,andto assure that the strip will be retained out of the path of the rotating punches and their carrying members'13. is shown pivotally carried by. arm 30 pivoted at 31 on bracket-32 carried by frame 1, (Fig.1), a spring 32 normally pressing said arm and roller toward strip 7. The rollers 26 and'27 are shown on the same'side of and below the punching devicesso that the members-13 may be-timed for rocking movements without undue speed and to al-- low ample time for the punchingoperations.

material 7 a single annularly disposed row of punches and corresponding holes-5 may be provided around the rotative headet. If two or'moreparallel rows of perforations or indentations are'to'be made in a strip the rows of holes may be appropriately located in the die plate 5 and the punches 6' may have corresponding spacedpunching pro ect1ons or pins for said holes. In the example illustrated have shown two=annular series ofblocks 8, side by side, on head The roller 29 4, each block having a rock-able member- 18' provided with punches; 6 and each block;

having a female die plate 5 for the-correspending punches, The opposing members 13-approach and recede during rotationwith' head't and their arms 18 extend outwardly in opposite directions to be actuated-- by corresponding-cams 16, shown disposed at opposite sides of the machine, (Fig;

The cam-member 22 has the previously describedcam. surfaces'on oppositesidestocooperate with the projections or rolls 23 0f the corresponding annularseriesof punches, 7.

whereby the punches will operatesubstan tiallysimultaneously'at a definite portion of sired spaced relation.

In accordance w-i'tlrtheexample illustrated, when strip-7 is inpositionon dies-5' and the head 4 is rotated some of the' memhere 13 will be in position over the stripend other ofsaid-members Will 'be away from said strip-more or less. Normallyon when i not punching the punches-wilhbe iir-tlie outer or retracted position, away from strip 7. When the, proj ections 23 ct the punches so 7 strip 7, along-opposites-ides thereof, in de approach and engage cam- ,surface' 22 the punches will be pushed toward strip-7 to perforate itand the arcuate-surfaces23' g and 23 -w1llreta1n said punches insuch-position;-

during travel of the punches with headfl, until the projeetions23 engage canr surface 22 whereupon the punches will be re tracted from i the dies and- "strip, being successively moved outwardly. Following the operation of one of the members-13 and; it's punches, let it be-assumed that-during its' rotation with head tall of itspunches have been retracted=from its: die 5 and-strip 7 3 itsdisk 17 having traveled through-the arcuate' portion 16 of cam 16, Fig: 4. Said dis-la next encounters the receding portion 16 of" cam 16 which will cause the disk to" approachshaft 2, thereby causin-g=member 13 to rockon its pivot 15 to carry'its punches;

outwardly to-one side-of theqplane of the adjacent edge-of strip 7 so that thepuncheswill be free to becarried around with head 4 without engaging thestrip. The lower curved portion 16"0f'cam 16 will retainmember-r13 and its punches retracted from strip 7, as head 4 is rotated, until the Where a single row of perforations or" indentations isto be produced in a strip of punches have passed to a positionwhere theywill not encounter theup-passing'ponover its die and over the unpu-nched' adjacent part of the strip on the die: Continued rotation of'head 4 will cause the projections r 23 ofthepunches of said member 13 to'sucF' cessively engage cam surface 22 to push the punches inwardly 'to puncture ofindent thestrip onthe die-5 said punches being're m0 tained in engagement with the holes in the strip to feed it by and with the punches while the said projections 23 travel between the arcuate cam surfaces 22 and 22 When the said projections 23 again encounter the eccentric or lateral cam surface 22 the punches will be withdrawn from strip 7, as before described. Corresponding operations, as above described, occur with each succeeding member 13 and its punches with respect to the cam member during rotation of head 4., whereby the strip is continuously punched or indented and fed as required. Since, in the example illustrated, the mem bers 13 are arranged in pairs the cam members 16 and 22 are correspondingly oppositely disposed so that the members 13 of each pair will approach and recede from one anotherv from opposite sides of strip 7 to cause the punches of each pair of said members to simultaneously punch or indent opposite sides of said strip, whereby the strip will be accurately held by the punches as fed thereby. The construction enables the holes to be punched in the strip always in positive spaced relation without danger of variation, which is particularly advantageous for moving picture films. Although the punches rotate bodily with head 4L the punching. operation is rectilinear, so that the punches enter the strip and recede from it in a right line so as not to distort the strip nor the edge of its holes 7 Having now described my invention, what I claimis:
