FILM-PERFORATING MACHINE.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application led July 28, 1909. Serial No. 510,093.

City, in thecounty of Hudson and State of t' New Jersey, have invented certain new and y useful lmprovements inlidia-Performing Machines. of which the following is a full,

clear, and exact specification.

My invention relates to machines for perforating sheets, and while it may be used for a lvariety of purposes where such operations are required, it is designed with a view to use in perforating reinforcing strips secured to photographic films such as are used in moving-picture machines.

The object of the invention is to provide vmeans for manually controlling the spacing between perforations, thereby insuring uniformity inthe position of the perforations and the registry of the perforations in such reinforcingr strips with the perforations in the film; also permittingl an uneven spacingY in` the original perforation to he corrected and to. enable such adjustment to he effected while themachine is in operation. 'lhese and other objects which will appea as the description proceeds, I' accomplish hy the improved construction of machine hereinafter descrilied and illustrated in the accompanying drawings wherein-5 t Figure 1 is a front elevation of my improved machine. Fim-2 is an elevation taken fromthe left, aiidpartly in section, on

the line 2-2 of Fig'. l. Fig. 3 ,is a rear ele- A .vation; and Figi'. 4 a plan view. l

': The long' films as usually supplied for inovinir.-picti.1- "mairliines arc perforated in use, and such reinl'oreements when applied cover the pertorations in thc lilm. lt necessary, therefore, tol pcrl'orate such lhesc perforations must register exactly with the .pcrtorations ex isting in the film in eases where thel latter was correctly perforated, and should correct any uneven perforation in the lihn.

VMy invention is designed to form such perforations in the reinforcing strips in exact register `with the previous pertoratlons where they are right, orto pcrtorate the .and standards 3 4.

tilm evenly where the'original perforations were uneven.

The main shaft of my machine runs from front to rear and the punches are situated at what I designate as the front of the machine.

Upon a bed-plate l is mounted the :trame of the. machine, comprising a base-plate 2, The front standard 4 may, if desired, lie formed with a stitlening weh 5. The upper ends of the standards are lprovided with bearings G, 7, for the main shaft 8. Upon this shaft is loosely mounted the driving pulley 9, which is oper-- atively connected to the shaft through clutch wh'eels 10, 11, the first of which is fixed to the pulley and the second keyed upon the shaft by key 12, so as to slid and is controlled by clutch-operating lever 13, fixed to the frame at 14. u

A film-carrying table 15 is supported at the front of the machine upon posts, ot' which 1G, 17, only are seen, but ot which there may be anysuitable nnmhcr.V The table is also supported hy a lnace 154, which is holted to its receiving,l end on the. inneil side and is also attached to a box-like frame 19, which has rails 20, 2l, situated uien each side ol the table and a stripper-plate 22 passing over the talde and lilm and holding),A the latter in place when the punches rise.

At the lett: ofthe table a pair of revolving guide-rollers Q25, Q4, are supported upon side-brackets 25, Qt, attached to the rails 20, 2l, sulliciently near together to guide the lilm '27 between them. As the lihn emerges from the guide-rollers, it, )asses along the tahle under the stripper-plate and is held in close proximity to the tahle adjacent the punchthy a flat-spring 28 (seen in section in ["ig'. 1') lormed out o'l' the stripper-plate hy slitting' the s:\ine,':iiid which has a springpi'e.-:s|ue upon the upper surface ot' the tilm.

hardened die, inserted in the table, is perl'orattnl at 2S) (Fig. l), to permit the passage of the punches 30, of which there are two, one'on cach side of the film, as seen in Fis: 2. V The punches are adjustahly mount- .cdin'a head 3l, which iS attached to a slidpitman 3.3 connects the block' with a crankcentric cam 37 (Figf),

in 36, mounted eccentrically upon the end of the main-shaft 8, and turning 1n thenpy per bearing of the pitman, whereby the rotation of the main shaft is converted into a reci rocation of the punch. Tiie feeding device is actuated by an ecfixed upon the main shaft at the rear of the machine and which rocks the rocking-arm 38 of a rocking lever through roller 39. This rocking-arm is fixed upon a rock-shaft'40, extending from front to 'rear of the machine, and is retracted and operated by a coiled-spring 4l, attached at one end to the said arm and at the other end to a bracket 42, projecting to the right of the machine from therear standard 3. The motion of the rocking-lever is limited in one direction by the cam Y37, and in the other direction by a stop 43, which is upon a lower extended branch ofthe rocking-arm and encounters the lower end of an adjusting stopscrew 44, which is adjustable for a purpose presently to be described.

Upon the forward end of rock-shaft 40 are fixed rocking-arms 45, which give a reciprocating motion to film-feeding fingers 46,

' which are lloosely hinged upon an axle 47,

" finger.

. a perforation and are which has bearings 'on the rocking-arms 45. Attached tc each finger is a short bracket 48 extending inward and which provides an auxiliary bearing upon the axle 47 for'the The fingers 46 are maintained in position to engage .the film by springs 49, mounted upon a rod 50, connecting the outer ends of the rocking-levers (Fig. 4) and these fingers at their free ends terinlnate in downwardly-extending hooks 51, which are adapted to enter the perforations in the film formed by the punch and-have their outer ends beveled to ride freely out of the perfoV rations in their forward movements.

The operation of that the feeding fingers move forward toward the punch to engage a-fres'h part of the film when the punch is down, thereb aviding an :liability that the fingers wil move the fi m the wrong way.' `When the punch rises the fingers are in position over forced down bythe Arocking-lever is retracted,

springs and the art of the film'under the feeding a fresh punch.

It occasonally'ha pens that filmsare improperly perforate when made, and this must be corrected. It also 'happens that films, from vagrious causes, mayre uire to be perforated, o that perforatons o different spacings--may be required. .loA enable this to be successfully accomplished, I have providedf my machine feedin mechanism,

,which I regardas` the `most important .feature of my invention.` of this adjustment the feeding;

By means fingers may be made to feed more or less fihn under the punch at each feeding movey ment, and

, imits the feeding movement of the feedlng device.

the machine is so timed Aof perforat-ons, upon a across the top of tuo brackets 65, which are with finely-adjustable thereby the space between erforations may be varied as desired This device is capable of fine and exact adjust-ment is maintained as long These results Iaccqm- 44 rwhich and the adjustmentas desired when lset.

lish by the threaded stop-screw feeding-' fin ers Fig. 3); This-stop-screw takes into I aft rea ed bearing 52, carried upon a rec- - tangular bracket 53, 54, which is supported u on posts 55 56, fixed to the base-plate 2'.

e stop-screw 44 carries a locking-wheel 57, formed 4With a series of locking, serrated teeth 58 upon its upper face near the perimeter, and these teethare engaged by a lock mg 60, carried by a brace ar 61, which at its front end is attached to the under side of the table and at its rear end is attached to apost 62 upon arm .53, situated under locking-wheel 57.

A spring (33 is coiled abouta stop-screw 44, and presses at and at the other end against the whee and serves to take up any lost motion in the threadof the stop-screw. It will be perceived that the rocking-arm 38, shaft 40, and

rocking arm 45 constitute a rocking-lever, by which, in connection with the cam 37, the rotary motion 'of the shaft is converted into a horizontally-reciprocating motion of the feeding-hooks and that the length of this motion 1n the feeding direction is Varied as the stop-screw is raised or lowered.

J The pitch of the screw 44, and also the lserrated locking-teeth 58 may be made as fine as desired, and the finer these parts are, the renter the extent of adjustment for the Means are also provided for clearing the erforations b v removing any bur or punchlugs from the perfor-ations that lhave not been entiely removed fronrthe film. A burrenioving device is shown atI the right of the machine. and in the illustration comprises a pair of spring-fingers 63a. one for each row bar 64, extending attached to the table.- Thesefingers have their ends bentv downfor entering the perforations, and tend to push out any adhering punchings. 'lhe fingers in their clearing acton are shown coperating with moving members. A serrated roller 66 is shown below each finger 63. The rollers 66 are fixed upon a revolving in an arm 68, lnouuted upon a post 70 and arm 59. which ispjvoted" upon a post.

one end vagainst bearing 52` shaft 67, having bearings an arm 69 adjustably mounted on posi-,175.:1

for adjusting the wheels 66 toward and from the fingers v631. Shaft 67 also has fixedI `thereto a pulley 71, which is run by crossed belt. 72 froni pulley 73 on the main shaft. As the. main shaft revolves inthe of the arrow (Fig. 1)', the toothed w ieels 66 4 will turn, as indicatedby arrowsmd will lrection mi j brush awa y, as it were, any adhering punchings, the coi'iperating devices (3"`serving to force the adhering punched out portions into engagement ivith the wheels (36.

The usual spool may be employed to receive the perfo 'ated film. but this is omitted for cleal'ness and as it forn'is no part of my i u vent ion.
