Machines, of which the following is a speciication."v

The present'ii'ivention relates to machines for renovating films for picture machines,

and is designed especially fonthe purpose of alo ` Fig. 7 is an edge view thereof.

washing, oiling and renewing moving picture iilms that have become soiled, strealred or oily from usage. 1

The invention consists in certain novel combinations and arrangements for accomplishing the above purpose involving 1wipers which clean and polish the film on bothiits sides as it is passed through the machine; in a particularly novel means for drawing the .film throuli the machine which accom' plishes its function without danger of breaking or injuring the film while under tension as it is being drawn through the machine; and in certain other features ris will be here inafter more fully pointed out.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invent-ion-con structcd according, to the best mode I have so far devised for the practical'applicationl of the principles of my invention.

Figure l is a front elevation of a machine complete involving the novel features of my invention. Fig. 2 is a side elevation as seen from'the right in Fig. 1. Fig. 3 is a rear elevation view. Fig. 4 is an'enlarged detail front View of one lof the film wiping devices. Fig. 5 is an edge ,view thereof.- an enlarged view of one of the fixed wipers. Fig. 8 is a sectional view of a film washing box: Fig. 9 is a sectional view of connections on the coun-- tershaft at the left in Fig. 1. Fig. 1li is a plan-view of onelof the winding tape reels with a spring brake. lFig 1.1 is a plaAn view of one of the tapefreels with its iatchet drive.

The film to be `renovated is fed trom one standard reel to a second winding reel of 'standard type', the movement of the iilm be ing a continuousone through the machine,

` wiper or rubbing tape which is operated in a step by step manner in order to present a continuously changing surface to the film. In the drawings the film is represented by a dotted line 1 which is unwound from the standard feed reel 2 and wound upon the Awinding reel 3.

The machine is coinpactly arranged, a post or standard 4:with a base 5 and supporting bracket arms 6, 6, 6, the latter eX- tending horizontally from the standard at convenient positions for supporting the different parts of the machine.

In describing the machine and its opera'- tion, the course of the iilm will be followed starting with the lilin reel 1. After leaving Patented Dec. 7, 1215.

the reel the film is preferably fed through them. The brushes are supplied with a suit- `able cleaning liquid from the respective res-A feed the liquid, which may be oil, through the box walls to the brushes as they revolve in contact with the ilm, one at the top and one at the bottom of the film and thoroughly cleanse and oil the film as it passes through the box.

The inlet and outlet of the box are provided with cushions, preferably of felt as 15 which guide the film as it enters the box and leaves it. The iilm passes from the box, and after being renovated as will be described, is. wound upon the winding reel 3. This Winding is accomplished by means of the conveyer belt 1G which is an endless belt as shown passing over the pulleys 17, 18, 19,' 20 and Apassing around the two end pulleys 17 and 19 as shown. The top pulley 1S is adjustably supported in the slot 21 (Fig. 3) so that the tension of thefbelt may be increased or diminished as desired. In Fig. 1 it is plainly seen that the film,l is held securely on the perimeter of the idler pulley 2O by tlle conveyer belt, and as the contact between 'the belt film and pulley extends throughout nearly one half the circumference of the pulley, it will be evident that the action of the belt and pulley will draw up the film., but without'strain. Thus as the underlap 'of the belt passes over the idler pulley between the two end ones, the film is drawn steadily up at one side of the idler andreleased at the other side, by frictional latter beinglixed to the lower end of averv tically arranged metallic bar 25 attached to Sfr and parallel withpost t. Above the two guide rolls 22, 23 are arranged a pair of jaws 26, 27, the former fixed and the latter -pivoted at 28 to the bracket arm. These jaws are faced with a soft material as felt, indicated at 29, and as the lm passes'between'the jaws, the pivoted one is pulled toward the iXed oneby a spring 30, and by this means, both sides of the film are rubbed by frictional contact with the felt pieces 29 and excess oil removed.

Above the stationary wiper or rubbing device just described, there are arranged two reciprocating rubbers indicated as a whole bythe numbers 3l and 32, the lower one (31) cleaning and polishing the right side ofthe ilm, and the upper one (32) cleaning and polishing the left side of the ilm. Both these devices are adapted to slide vertically upon the metallic bar 25 iixed on the post 4, and inasmuch as the construction of each isthe same as the other a description of one will suffice yfor the other. Referring particularly to Figs. 4 and 5 which show the rubbers orwipers on an enlarged scale. Each rubber includes a metallic plate 33 'formed with a right angular flange 3e which is covered with tape or other soft material at 35,

its ends being bent over'the ends of the flange and secured by screws 36 which also attach the upper and lower roller brackets 37 and 38 to the iange. Each of these brackets carries a pair of guide rollers 39, 40, adapted to guide the rubbing ta e 41, or42 as the case may be, so that it wil pass freely over the fixed tape 35' on the flange 34. rllhe tapes 4l and 42 are designed to rub the iilm, and to hold, the iilm in position so that it may be rubbed, l employ a series of rollers 43," 4A, e5, each journaled in a bracket arm 4:6 that is pivoted at 4:7 to the plate 33 and pulled toward the rubbing tape by their individual springs LlS-that are attached at 49 to the Hangs 34. ln Fig. 5 it will be noted that the roller 44C is somewhat the shape of a barrel or convened, and this construction is provided to insure that the central portion lti are each provided with a slotted head 50 adapted to slide upon the bar 25, and a crank 51 on the shaft 52 (Fig. 2) has two crank arms and links 53 and 5ft connected to the studs' of the heads, so that the rotary movement of the crank shaft is converted into reciprocatory movement of the two wipers or rubbers. The rubbing tapes 41 and are wound upon similar drums or reels 56, 57 from unwinding reels r53, 59, the two latter reels being provided with'springs 60 for frictional engagement to act as brakes to prevent excessive revolution of the reel and to keep the tape taut between its reel and the rubber.

The winding tape reels 56 and 57, each has a lwinding ratchet wheel 61, a lever 62 and pawl 63 engaging the ratchet wheel, and the two levers are pivotally connected by the link 64. A second. link or rod 65 is connected to the slotted arm 66 ot the pulley 67 on the countershaft 67 so that as the shaft revolves the ratchet wheels are moved through the connection with the pawls so that the rubbing tapes are wound upon their winding reels 5G and 57, thus continually presenting fresh rubbing surfaces to the lilm. Pulley 67 is moved from shaft 52 by pulley 68 and belt 69a. Above the reciproeating rubbers a second set of auxiliary brushes 68 and 69 are provided, being revolved from the Pulley 70 and belt 7l on the shaft 72 which is revolved from the conveyer belt 16, and crossed belt 68a.

The winding reel 3 is revolved by belt 72 and pulley 73 from pulley 7i on the crank shaft 52, and this provides for winding the film after it has passed over the idler pulley 20. The crank shaft is revolved from the motor 75 through 4the pulleys 76, 77, and belt 78, and the brushes in the washing box are revolved from the crank /shaft through pulley 79, belt 80, pulley 8l, shaft 82, the latter being the upperbrush shaft, and the lower brush shaft 83 is revolved from shaft 82 by pulleys 8i, 86 and belt 85. The speed oftr'avel the rubbing ta es eil and l2 may be adji'isaed to' suit conditions, and for irstance the nlm. is in a bad condition. the 'travel of the rubbing tape may be increased. This adiustmes change in the crank motion increases or .de

creases the travel ci? the ratchets 31 to drive the tape reels 56 57.

The ilin moves slowly, .in aisubstantiallv-` straight line, but the reciprocating rubbers move swiftly, in opposite directions'as de scribed- .'lhe auxiliary bur'mg wheels or brushes 6869 remove any lint, dust or other foreign matter from the ilni before it is finally wound in clean condition ou tite winding reel 3. A' cut out for the counter shaft is shown in 5l, where the ceci* bined belt pulley 19 and hand Wheel 19', at this point may be disconnected by the pin 20 between the crank arm 2l and wheel 19. This allows hand operation of the conveyer belt sov that the film can be drawn through the machine if necessary, leaving the remainder of the machine idle, and this arrangement lalso facilitates threading of the film through the machine. rlhe wiping or rubbing tapes are readily removable and'replaceable when desired, and when worn on one side they may be rev versed and the other side used as will be understood.. The continually moving rubbing tape presents at all times a fresh rubbing surface to the film, and it will be unders'tood that the travel ofthe tape may be varied as before described.

I claim 1. The combination with means for continuously moving a. film, of a exible rubbing tape in frictional contact with the film at one side, and resiliently supported means at. the other side of the film for guiding lthe film in contact with the tape.

2. The combination with means for continuously moving a film, of an intermittently moving flexible rubbing device at one side of the film, and resilient guide means for" holding the film in contact with said device.l

3. The combination with means for con tinuously moving a iilm, of a reciprocating device carrying anv intermittently moving flexible rubbing tape at one side of the film, and resilient guide' means at the other side of the film for holding itin contact with the tape.

4. The combination with means -for continnously moving a lm, of a bodily reciprocable device carrying a flexible rubbing tape at one side of the film, resiliently supported guide rolls at the other side of the film, and a cushion belt passed around said rollers.

5. The combination with means for continuously moving a film, of a bodily reciprocable device carrying a rubbing tape at one side'of the film, and aseries of resiliently supported guide rolls at the other side of the film, one 0f said rolls being provided with a convex periphery.'

6. The combination with means for continuously moving a. film-, a pair of rubbing devices one in frictional Contact at each side of the film, and means for synchronously .reciprocating said devices in, alternately opposite directions.

In testilnony whereof I aflix my signature in presence of two witnesses.
