To all wiwi/b t may coo-ern:

Be it known that I, ALBERT S. HOWELL, a citizen of the United States, and resident of Chicago, in the county of Cook and State` i of Illinois, have invented certain new and useful Improvements in Apparatus for Perforating Cinematographic Films, of which the following is aspecification. u

My invention' relates to apparatus for perforating the margins of cinematographic film, and more particularly4 to an apparatus of `this character that is capable of feeding the film, for perforating1 the same, and for discharging and* rewin ing the film after the perforating operation.

One of the objects of my invention is the provision of a machine of this character that is adapted td Aperform all of itsY functions in an automatic manner in order that the attention of the operator is un- Further objects of my invention comprise the construction of a perforating machine `for 'motion picture film that is compact 1n construction and efficient in its operation in handling and operating'upon the film, and also the provision of means whereby the movement of the ram, which carries the perforators, may be adjusted. And a further object of my invention isthe provision of`a`?" holder and stripper-that is adapted to retain the film during the punching operathe removal of the same from the dies immediately thereafter. I have also provided a novel shuttlel mechanism and pilots that are together adapted to accurately move the film 'longitudinally and position the same immediately prior to the/ punching operation.v Further objects of my invention will be obvious after an understanding of my in- A vention is had from the vfollowing description. I prefer to accomplish the divers objects of my invention in substantially the manner and by substantially the means hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying `drawings forming a part of this specification, in which- Figure 1 is a longitudinal front elevation of my perforating machine for cinematographic film. l Fig. 2 is a vertical transverse section on line 2-'2 of Fig. 1 looking in the direction of the arrows, the lower portion of the ram and the discharge'end of thecarriage or bed being illustrated in end elevation.

Fig. 3 is an enlarged fragmentary view of the shuttle and stripper mechanism, to-

gether with'the operating levers, the upper fportion of the apparatus being removed for clearness.

Fig. 4 is a top plan of the bed or carriage, including the guides through which the cinematographic film is adapted to move. Fig. 5 is a fragmentary view of a portion of the mechanism shown in Fig 2 and'in enlarged detail.

Fig. 6 is a perspective view of the shuttle for moving the film.

Fig. 7 is a perspective detail of the V-block employed in conjunction with the shuttle (Fig. 6) for longitudinally reciprocating the latter.

Figs. 8 and 9 are, respectively, yplan and side views ofthe stripper plate. l Fig. 10 is an enlarged longitudinal section of the stripper plate.

Fig. 11 is a vertical longitudinal section of the means for actuating the film spools.

Fig. 12 is a rear elevation of the ram and Referring to the drawings, it will be obl' served that my invention preferably comprises a suitable standard A, upon the upper end whereof is mounted a table D that is adapted to support-the bed or carriage and theguideways for the film and `said table isl providedbwith a segmental upright arm C. The upper end of the arm C terminates in' a rectangularly shaped slideway or housing D in which the ramis adapted to reciprocate, and intermediate this housing D said 'arm is provided with bearings for ldivers elements of the mechanismfas will hereinafter more fully appear,

gg 4 'i A 1,291,524

Mountedupon opposite sides of the housing D, adjacent the lower end thereof, are laterally disposed tubular brackets 20, 21, the outer ends of which are preferably pro- 5 vided with upright brackets 22 and 23, re-

spectively. Suitable bearings are provided in the upper ends of brackets 22 and 23, and` arbors 24 and 25, respectively,vare mounted therein soas to journal' film spools thereon and the usual retaining disks 26 are secured thereon to guidel and keep the film on'the film spools in compact form.

`The roll of film is placed upon arbor 24 and threaded around an idle roller or spool 27 journaled upon "the end of arm 2() and i thence passes over a larger flanged roller 28 mounted upon a spindle 29, upon the adjacent end of arm 20, and is retained thereon throughout a major portion of the circumference ofI said roller 28 by a presser roller 30. The roller 30 is journaled in the movable end of a spring pressed arm'31 pivoted upon a lateral bracket 32 projecting from the adjacent end ofthe arm 20. Upon leaving the spoolv 28 and roller 30, the film is looped and 'passes over -a guide roller 30a and into the receiving end of the bed or carriage of the machine, illustrated in detail in Fig. 4 of the drawings. v The bed ol carriage is of such construction that the film will travel therethrough in a manner so that the emulsion surface thereof which is uppermost will not be engaged or 'come in contact. with any of the elements of 35 the carriage at the portions that afterward 'receive the pictures, and thusl avoids the liability' of spoiling or marring the sensitized surface. The specific details of the bed Vand 'carriage form the basis of a co-pending application executed by me even dateherewith 'and filed March. 2nd, 1917, Serial No. 152,010, and, therefore, does not require a detailed description. kHowever, it will be observed that the bed or carriage comprises longitudinally disposed parallel" blocks 33 that are secured to the' upper surface of an adjustable wing B 1 of the table B, and are provided with a plurality of 'small rollers 34. There are preferably three rows o-f these rollers`,a center row which supports the central portion of the film and two outer rows that carry the marginal edges of the film, the latter or outer rows being so disposed that 'they' will engage the film at or outside the line or part in which the perforations'are to be made. Above the base blocks 33, at one side of the film path, is removably mounted a guide plate 35 that has a row of e.

rollers 36 journaled adjacent the edge, there- 00 of and is adapted to guide and position the -ffilm with respectto the perforating dies. The rollers 36 register with and are above the-adjacent row of rollers 34. A-removable yielding guide plate 37 is mounted upon the t5 opposite side of the bed or carriage and likewise is provided with a row of rollers 38 that register with the rollers inthe base plates immediately below the same. The spring 39 normally keeps said plat-e l37 pressed toward the film in a yielding manner and is adapted in this way to take care of any unevenness in the adjacent edge of the film due to transverse shrinkage of the emulsion. It willbe seen that all these rollers co-act to present the film to the punches in a horizontal plane and flat and even. Arms 40 and 41 project, respectively, from the ends of guide plates 35 and 37 and eX- tend upon opposite sides of the lower perforating die to form a. film channel across the same and guide the edge of the film while adjacent the dies. The guideway for. the discharging end of the table is constructed similarly to that. just described and coinprises base blocks 42 having rollers 43 jour- 85 naled between the same and are secured upon a wing B2 of the table. A removable skeleton plate 44 is adapted to be slid into suitable guide passages above the base blocks and is' provided with marginalrollers 45 90 that engage the upper surface of the edge of the film after it has passed from the punches. A latch 46 is adapted to removably loclrthis skeleton plate 44 in its guideway and the rollers of said skeleton plate register with 9 the marginal rollers journaled between the outer base blocks 42. It will thus be seen that a continuous guide is provided for the film from the receiving end past the' dies and out the discharge end of the table.

After the film has passed from the discharging end of the table it is loopeddown slightly over a guide roller 45L and then drawn upwardly through a suitable film cleaning device E, the details of which are fully set forth in an application executed by me November 16, 1916, and filed November 27, 1916, Serial No. 133,768, for a device for cleaning film. The cleaning device is carried upon pendant ymember 47 projecting 110 downwardly from the outer end of the arm 21. The film is thoroughly cleaned of any foreign matter by the cleaning device E and thence passes upwardly overa sprocket 48, around an idle roller 49, and is rewound upon the spool carrie-d byA arborA 25. A

presser roller 50 keeps the film firmly pressed upon the sprocket 48 and is similar in construction tothe presser roller 30 upon the opposite end of themachine. The spool upon arbor 25 is driven by means of a drive pulley 51 journaled upon the end of arm 21 and a belt 52 that connects said pulley 51 with a pulley 53 upon the spool on arbor 25.

Intermediate its ends the arm C of the table is transversely bored at 54 and in its opposite ends said bore is provided with `anti-frictional ball bearings 55 and 56 for journaling the main drive shaft 56. The outer end of shaft 56 extends beyondvits 130 l lower end engages the pin 79 and locks the bearings and has a drive pulley 58 secured 1fthereonwthat vderives its motion. from a suit- "ablevamotorby means 'of a belt or otherwise.

-zontally disposed transmission shafts 61 and 62, respectively. The outer ends of these shafts are respectively provided with spiral gears 63 and 64 that mesh with spiral gears 65 and 66 carried upon the spindles X and l29, respectively. It will be seen that the rotation of the drive shaft 57 transmits its motion to a spiral gear 67 connecting the shafts 61 and 62, which in turn transmit the motion to the spiral gears upon the ends of the respective transmission shafts and drive the respective pulleys for feeding the film to the carriage and withdrawing it therefrom.

The slideway or housing D is of rectangular shape and substantially U-shape in horizontal section, a facing plate or closer 68 being secured to the outer vertical edges of the horizontal or lateral members to provide a suitable guideway 69` wherein the reciprocable ram 70 is mounted. The rear surface of the ram, nearest the shaft 57, is preferably provided with a recess 71 of dumb-bell outline, in which the operating element is conveniently set. This element comprises a link 72, the ends whereof are lobe-shape or circular, so as to provide seats to receive anti-frictional roller bearings 73 and 74. A crank pin 75 mounted eccentrically upon and extended from the adjacent end of shaft 57 engages 'the link in its bearing at its lower end, and the upper end of the link is connected to the ram by an adjusting member76, having a .lateral eccentric stud 77 projecting from the end thereof adjacent the upper end of the link. This adjusting member 76 is preferably cylindrical in shape as shown in detail in Fig. 2 of the drawings, and is provided with a concentric recess or groove 78 into which the lower end of a pin 79 fits. A set screw 80 is tapped into the upper .end of the ram so that its same together with adjusting element 76 in divers positions and headed nut 81 is mounted upon the outer end of the element 76 and access is had to this nut by means of an."

aperture 82 in the facing plate 68. It will be observed that by releasing the set screw the adjusting element may be rotated by means of the nut-'81, thereby raising or lowering-the eccentric stud 77 0n the Oppo- (site end thereof which thus raises and low- `ers the ram with relation to the lower die members ofthe perforator and alters the inithe ram with.

suitable manner and is provided with' extensions 84 between which the said pilots and perforators are mounted.` Suitable retaining plates 85 are secured to the opposite sides of these extensions 84 to form a box or tool holder in which these pilots and perforatorgl are mounted. The pilots comprise a plurality of vertically disposed parallel pins 86, arranged four upon each side, for the purpose of engaging `the film adjacent the margins and are adapted to enter the perforations previously made by the punches. The punching members coniprise a plurality of blunt pins or entering die members 87 arranged in longitudinal alinement with the pilots 86, preferably four in number, for each margin of the film. Taken together the ,pilots and punches provide eight par allel members that are moved simultaneously downward toward and engage the film that has momentarily been stopped to be perforated. After the machine has been started the pilots will engage the four perforations made by the previous operation of the dies and are longer than the punches so that they will engage the film and position itwth accuracy when the punches which are simultaneously approaching` the film engage the latter and perforate the same in the correct position. Opposing the ram, and the pilots and punches, is the lower die member 88across which the film is adapted to be guided by the carriage and bed structure heretofore described, and which preferably comprises a rectangularly shaped plate (Fig. 4), the longitudinal and transverse edges whereof are fitted snugly between the guide plates and guide arms of said carriage. The longitudinal edges of this die 88 are provided with marginal rows of recesses or openings 8-9, preferably eight upon each side to receive the pilots` and the punches that coperate therewith Inord'er to strip`the film from the pilots and punches when the same are being withdrawn from the film, I have provided a suitable stripper plate 90, shown in detail in Figs. 8, 9 and 10 of the drawings. This plate, as will be observed, is of substantially rectangular shape and its outer portion is preferably .provided with longitudinal#rib.; 91, between which are two rows of apertures 92 through which the pilots and punches pass. The under surface of this stripper plate is preferably provided with transverse ridges 93 that are disposed in vvertical alinement with the rows of apertures above meutioned, so that the plate will engage the film only at its* ma-1'gins and adjacent the path of the perforations, so that it will not mar or injure the sensitized emulsified surface thereof. The Istripper plate is mounted upon the end of the irregularly shaped bellcrank lever journaled on a stud S34-projecting from one side of the upright segmental arm C.

The horizontalmember 95 of this bell crank projects forwardly in an oblique manner to- .ward the ram and isthen defiectedr slightly so that its end portion lies parallel with the' line of movement o f the film where it is proment 96 to the under surface whereof the vided with a. rectangularly shaped embossstripper plate 90 is secured. The upright member 97 of this bellvcrank extends upwardly slightly oblique to ay true vert-ical plane and is provided with a base 98 in its upper end that is bored horizontally to re*` ceive a suitable spindle 99 for a rollei 100 that is journaled on the end thereof. The

,- roller 100 is adapted to ride in a peripheral cam slot l01 in t-he edge yof a cam disk 102d journaled upon thegextended end ofthe-drive shaft 57. The vcam slot 101 is `so constructed that the bell crank is adapted tovraise the stripper plate 90 the moment the film Vis moved by the shuttle mechanism and is lowered immediately the movement of the film is stopped. The cam slot, for convenience, is

made in the bottom of another cani slot 103,

. the purpose of whichwill hereinafter-appear. v

The means for moving the film strip after it has been perforated preferably comprises .a suitable reciprocable shuttle that 'is provided with means for engagingthe perforaially so that it may be mounted to lcate longitudinally upon an elongated stud 111 projecting from the adjacent end of a,

tions and withdrawing the film from the dies, after which' the shuttle is lowered out of engagement with the film and is returned to its initial position to engage the' next set of perforations. This film actuating member comprises a. shuttle that consists of an elongated sleeve 110, hthe details whereof are' illustrated in the perspective view (F ig. 6) ofthe drawings. The sleeve 110. is bored ax-" reciprobell crank and is disposed parallel to `the ,path of movement of the vfilm, and extends under the perforating dies into a suitable cylindrical chamber 112 made in the table below the b'ed. Intermediate `its ends this sleeve is provided with .an upstanding T- shaped bracket 113, from the upper surface of each of the arms whereof project a pluralit-y (preferably four) of picks or fingers 114. The T-shape member 113 is providedA \with a slot or guideway 115 extending transversely of the axis of the sleeve and open at the top andsides, and a suitable actuating guide block 116 is disposed therein. The

guide block just mentioned is provided with downwardly projectingv end extensions 117- that engage the flat vertical surfaces '118 of the shuttle so that said block may be raised yrocation of the shuttle -end of a bell crank stud 119'mounted upon the adjacent end of a vibratory crank arm 120. The crank arm 120 depends from the inner end of a rock shaft 121 that is disposed in horizontalbearings 122 in the arm C of the apparatus. The opposite or rear end of rock shaft 121 ex# tends beyond its bearing and has a4` suitable cam arm 123 secured thereto so that 'the up- .per end of the latter will be disposed adjacent the horizontal plane o-f the axis of drive shaft'57i A transverse or lateral spindle is mounted in the upper end of cam arm 123 and carries a. roller 124 upon its end nearest the cam disk 102 heretofore mentioned, and is adapted to ride in and be guided by the cam slot 125 made in the outer face of this cam disk. The cam slot. 125 is so plotted that the shaft 121 is rocked sufficiently to cause the crank ing the block 116 and moving the shuttle longitudinally upon the stud y111. This reciproc'ationis preferably of a length corresponding to the distances between four successive perforations in the film, it being customary to provide four perforations to each margin of a picture that is afterward developed upon the sensitized film, and' this movement is sufficient to shift the film so that the perforations that have just punches 87 will be'moved in position to receive the pilots 86 which position the -film for the neXt succeeding set of perforations. It will be observed that the horizontal recipis caused' by a somewhat segmental movement of the block 116 sliding vertically in the guideway 115 of the shuttle, but the upper edge of the block does not reach aplane which would rise above the 'path of the lm and interfere `with themofement of the latter. v

In order to impart to the film actuating shuttle an up or down movement at e'ach end of itshori'zontal reciprocation, the stud 111 is preferably carried upon the adjacent pivoted at its elbow upon a suitable stud 126 projecting from the side of arm C ofthe apparatus. tally disposed arm 127 of this bell crank carries the stud 111 while the vertical arm 128 extends obliguely upwardV and terminates in substantially the horizontal plane 120 to vibrate, thereby reciprocat- .i

been made by the The ,horizonv of the axis of drive shaft 57. A suitable roller 129 is mounted upon a lateral stud 130 in an embossment 131 at the upper end I 'of arm 128, and this roller 129 fits into the outer or wider slot 103 heretofore'mentioned, so that the arm 128 is vibrated laterally at. its upper end,` thereby imparting a vertical vibration to the outer end of its horizontal adapted to engage 121 and its associated members 120 and 123 are so synchronized or timed with respect to the movement of the stud 111 that the latter is raised at the innermost end of the move` punches and pilots are' started in their downward movement. Thel strlpper plate 90 is likewise timed to be elevated immediately the puncheshave been withdrawn and the fingers have begun theirengagement with the film and is lowered into engagement with the film immediately prior to the withdrawal of the shuttle fingers from the film so that at all times during the punching operation, (in other words, when the punches and pilots are moved down and up,) the stripper plate engages the film land simultaneously with the insertion of the shuttle fingers the stripper plate releases its hold upon the film and vice versa.
