To all whom it may concern: y

Be it known that LIUCHARD D. HANIsi-i, a

citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for Renovating Picture-Films, of which ing is a specification.

The present invention relates to improvements in machines for renovating picture films, and is especially applicable for cleaning, polishing and renewing the films of moving picture machines.

he provision of machine to be used in connectio-n with an oiling, washing and cleaning process, in order used films by removing scratched and worn, rough or cracked surfaces due to'wear upon the films after they have been used for a considerable time. New films may also be treated and polished by this machine in order to produce thereon a better surface and to lengthen the life of the Vnew film by rendering liability of wear less likely.

In the accompanying drawings I have `illustrated one complete leXample `of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

rIhe invention consists yessentially in a machineembodying meansV whereby a lm,

which has been previously oiled or not as desired, may be unwound from one spool or reel to a second spool and reel, and during the interval of transmission, means are ac tuated for polishing one or both sides of the film as it moves. Certain other combinations of parts are embodied inthe machine such as means for retarding excessive feed of thev film from the unwinding reel, and for compensating. for increased diameter of the winding reel as the film is wound thereon at the opposite end of the machine. Y

` In the preferred embodiment of my invention I. have shown the operating parts of the machine mounted upon a frame 1, and in the frame are illustrated four large polishing wheels or drums 2, 3, 4, 5, preferably constructed after the manner shown in my Patent No. 1,071,519, issued August 26, 1913, the direction of the arrows, in pairs, through their shafts 6, 7, 8, 9 which are journaled in the frame 1. The shafts are all driven from the .driving pulley 10 and pairs of gears 11 and 12, the shafts 6 and 7 Y being rotated in the same direction through the wheels 13 and 14 and belt or chain 15. The shafts 8 and'9 are rotated in the same direction through the wheel 16, chain 17, counterwheel 18 on a short shaft 19 in the frame, and the two gears 20 and 21, the former on the shaft 19-and the latter on shaft 8 and the sprocket wheels 61 and 60 on shafts 8 and 9 respectively and chain 62. It will thus he seen that the two drums 2 and 3 are simultaneously revolved anti-clockwise, and the two drums 4C and 5 are similarly revolved clockwise. These drums are covered with suitable polishing material and are adapted to polish the film by frictional contact therewith, two drums acting on the upper surface of the lm F, shown on Fig.

kthe process of cleaning 3 and shown in dotted lines in Fig. l, and two drums acting on the lower surface as the film passes through the machine. The drums are of considerable width, and in the drawings they are wide enough to polish three films simultaneously, although of course this number may be varied and a larger or smaller number of films may be cleaned at one time, depending upon the width of the drums.

The films pass from left to right in the machine, and as the mechanism for transmitting the film is the same in each case,

one iilm will be described herein as applicable to all the films and mechanism therefor.

The winding reels arc indicated by the numerals 22 and the unwinding reels by the number 23, and these reels are of the usual standard construction for picture films, although of course other reels may be used on the machine with equal facility. These reels are adjustably supported, as will be presently described, to bring the films into contact with different portions of the cleaner structure, so that when one portion is soiled, the film may be readily shifted to a cleaner surface.

In Figs. 4, 5, and 6 the unwinding reels are illustrated in enlarged detail, and it. will be seen that they are supported upon two cross bars 24 by means of the movable and adjustable bracket or frame 25 which has perforated ears 26 to slide on the bars and at least one set screw 27 to secure the frame in adjusted position on the bars. The frame is provided with a plurality of uprights or bearing brackets arranged in pairs as 28 and 2.9, integral with the frame and projecting vertically therefrom. The bracket 28 of the frame is recessed or formed with an open perforation at its upper end to receive the trunnion or journal 3() of the reel, and it is also provided with au arm 31 extending to the front and an arm 32 extending to the rear of the reel. The arm 32 is bent as shown and provided with a perfoi-ated ear at its end to form part of a hinged joint 33 by means of which the hinged arm 34 is connected to the arm This hinged arm 34 also has an open perforation as 35 for the trunnion or journal 30, and a spring held catch 36 which cooperates therewith to hold the journal in the recess as will be understood. The two arms 3l and 34 and the front arm 32 embrace one end and the two sides of the reel, and at the front, the perforated ends of the arms 31 and 34 are connected by a bolt 37. l'lhe ends of the arms are spaced apart by means of the spring 33 coiled about the bolt and located between the arms, but the arm 34 may be moved toward the reel on its pivot 33 and there held by means of a wing nut 39 on the threaded end of the bolt 37 ln this manner it will be understood that the pivoted arm 34 may be made to swing on its hinge 33 toward or away from the reel, and when swung toward the reel, by turning the nut 39, the arm is made to frictionally engage the reel to retard or brake its movement. To facilitate the movement, the upper end o f the bracket 29 has a dovetail slot 40 for the tongue 4l of the arm 34 to slide in, and in this manner the excessive move ment of the reel and consequent unwinding of the filmv is prevented. lt will be understood that the frictional engagement of the arms with the reel may be adjusted to suit circumstances by means of the wingv nut 39, and the unwinding of the film from the reel regulated, and by means of the slidably movable frame 25, the position of the unwinding reels may be laterallyV adjusted to feed the films to the cleaning or polishing rolls.

'f he winding reels 22 are supportedon cross bars 42, and adjustable frame 43 with its ears 44, may be held in adjusted position by means of the set screw 45,` as in the case of the unwindiug reels, but the frame is equipped with brackets 46 arranged in pairs and having open upper bearings 47 closed by pins 48. These bearings furnish the support for a specially made, sectional shaft which revolves with the winding reels. The shaft is made up of a plurality of sections 49 upon which reel is held to rotate by a spline or key 50. it its ends each section is formed with a tongue 5l and slot 52, and in Fig. 3 it will be plainly seen that the tongue and slot connections or joints rest in the open bearings 4'( at the upper ends of the brackets 46, and the supported joints thus form a continuous shaft with which the reels, that are keyed thereto, move or revolve, to wind the films from the unwinding reels.

lhe winding reel shaft which designate as a whole in Fig. 2, as 53 carries a wheel 54 that is revolved from the drinn shaft 8 through the medium of the chain 55 and wheel 56, and the clutch 57 operated by handle 53 is employed to connect or disconnect the shaft 53 with its driving means. As

the film winds on the winding reel the diameter of the roll on which it is wound increases as will be readily understood and consequently its rate of linear travel is correspondingly increased, while the speed of these films should desirably be kept constant. To compensate for this difference and variation the sprocket wheel 55 is held to revolve with its shaft 9 by a wing nut 59 bearing against spring 59a which .is adapted for frictional Contact with the wheel, and by means of the nut the spring may be adjusted so that it will allow slipping and .lost motion ofthe wheel 53 as the diameter of the hn on the winding reel increases.

" between the roll and reels,l they are supported thus permitted to have 25 f The shaft 9 is revolved from the shaft 8 .through the sprocket wheels 60, 61 and chain62. As the films pass through the machine from the unwinding 4reels to the winding adjacent the polishing rolls or drums by resiliently suspended seen that the films pass under rolls 63 and 66 and over rolls' 64 and 65 and that the respective polishing drums are in position for frictional Contact with the films as they pass over the rolls, to polish both sides of the lms.

lReferring to the rolls 63 and 66 under which the film passes in Figs. 1 and 27 it will be seen that these rolls are supported each from its respective suspending arm 67, 68, and that the arms are formed with hubs 69 that are rotatable on the cross bars or rods 70. By means of a spring 71 the arm 67 is resiliently suspended over the drum 2 and the film as it passes under the roll 63 is a light contact with the polishing drum. Each arm carries guide rollers 72 that are relatively fixed on the arm, and an adjustable guide roller 7 3 that is journaled in a pivoted bracket 74 which is urged toward the roll by Vmeans of a spring pressed pawl 75, or rather held in position adjacent the roll by said pawl, but a spring 76 tends to pull the roller from the roll. This arrangement is provided so that when the film is being threaded through the machine the pawl 75 may be disengagedV and the roller pulled away from the roll b spring 7 6 to facilitate the passage of the iilm roller. There are, of course, three of these suspending arnis for each drum, the arms 67 and 68 and their accessories, being identical except that they areV arranged to operate on the right and left hand end of the machine respectively, while somewhat similar arms '77 and 8 are arranged in sets to carry the rollers 64- and 65 respectively. A description of the arm 77 in Figs. 9 and 10 will be suflicient to distinguish and identify these devices. The arm is formed with the hub 69 revoluble on the bar 70 and is supended fromthe frame by a spring 7 9 which tends to pull the roller 64 toward the polishing drum 3. Flanged guide rollers 80 and 81 are located at the sides of the roll 64 and these rollers are journaled on the respective brackets 82 and 83 which are pivoted on the arm 77 and oonneoted by a spring 84 which tends to draw the rolls from the roller. The rollers are held in position adjacent the roll however,

by means of duplicate pawls 85 which are spring pressed and have hooks 86 to engage in a recess 87 formed in each of brackets.

-en the film is to be threaded on the machine the hooks 86 are disconnected, and the In F 1 it will be degree spring 84 draws the brackets so that the rollers are withdrawn from the roll and the film may be passed under the rollers and over the roll with facility. It is desirable, although not always necessary that the films be coated with oil before being polished on the machine, and for this purpose an oiling device is positioned at the side ci thc machine and forms a part thereof. This oiling device comprises an unwinding reel 88 and a winding reel 89, and the unwinding reel is provided with a brake or retarding device to prevent excessive unwinding of the film therefrom. To this end one of the supporting brackets of the reel, as shown in Fig. 11 is provided with a pivoted arm 90 positioned between the forked bracket 91, and the spring 92 between the lower end of the arm and the opposing bracket or post of the reel support tends to urge this lower end outwardly and the upper or journaled end 93 is urged into frictional contact with the reel. By means of a winged screw 94 the of pressure of the spring may be regulated as will be understood.

The iilni is moved from the unwinding reel to the winding' reel of the oiling device and passes between an oil-coating pair of rollers 95 and 96. The iilm is coated by the upper roller 96 which receives oil from the tank 9'? through the transfer rollers 98, 99, 100, the roller 98 being partially immersed in the oil while the roll 100 contacts with upper roll 96. .it is necessary to coat only one surfaf'e of the film, the upper surface, as it will be understood that when the film is 'wound upon the winding roller a coating` of oil will be transferred from the upper to the under surface of the winding film. The oiling device is operated from the shaft S through the medium of the clutch 1L01, wheel 102, chain 103 and wheel l04, as indicated in Fig. 2, and the winding .reel of the oiling device is rotated from shaft 105 of the wheel 104 through wheel 10i` and chain 107, and the wheel 108 on the reel shaft 109. A friction device 110 similar to the device 59 is also employed in connection with this winding reel. After the film has been coated with oil, or oiled in the oiling device and wound upon its reel, the reel with the film thereon is detached from the winding shaft 109 and is placed on the shaft 30, or rather the shaft 30 is passed through the bearing opening in the reel, and the reel is then suspended by its shaft in the journals as shown in Figs. 4 and After the films are in place on the unwinding reels and the reels located in proper position` the films are successively threaded through the guide rollers and rolls, as described and attached to Ithe winding reels. ylhe driving mechanism is then started, and the lilms are wound from the reels 23 to the reels 22 as shown by dotted i may lines and arrows in Fig. l. The films are designed to move slowly from left t0 right, alternately under and over the rollers 63, 64, 65, 66, while the large polishing drums 2, 3, Ll, 5, which polish opposite sides of the films, move at a relatively greater speed of rotation. The .interposition of the two gears 20, Q1 (Fig. i2) in the transmission mechanism serves to reverse the direction of the drums l and 5, as indicated by the arrows. By the utilization of the rolls on the yielding or resiliently supported arms, the films may be threaded through the machine with facility, and the films may be caused to engage the polishing drums with the proper degree of frictional contact to insure most efficient work, which degree of frictional contact may be ascertained by experiment, and the adjustment fixed as desired.

By the utilization of the specially constructed sectional winding shaft 53, l am enabled to remove a wound reel at will and substitute an empty reel, without disturbing the remaining reels, by disconnecting the section e9, removing the section and its reel from the shaft and then ren'ioving the reel from the section and replacing the section and a new reel on the shaft.

Guide rollers 95 may be employed in the oiling device to guide the film to the coating rollers, and it will be understood that the roller 99 which is in a pivoted bracket 99 be lifted for a time from contact with rollers 98 and 100, if it is found the oil is being fed excessively.

|The oiling rollers 98 99 l0() are revolved while in Contact by means of the train of gears indicated in Fig'Q at A, B, C.

The oil referred to which is applied to the film before it is cleaned or renovated may be of various characteristics, and may be changed to suit the conditions existing in the films. lt will be noted that the rotary movements of the pairs of drums are in reverse directions and that as a consequence the drums 2 and 3 draw the film to the right while the two drums 4c and 5 tend to retard the movement, thus equalizing the passage of the film through the machine.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is z- 1. A film renovating machine comprising a general framework, of at least double the width of a film and arranged to come into cleaning contact with a film, a rotatably mounted unwinding reel, a. rotatably mounted winding reel, and means for adjustably so that they may be adjusted laterally to bring the film into cleaning contact with different portions of said cleaner structure.

2. A film renovating machine comprising a general framework, a cleaning structurev of a Width to accommodate a plurality of films and arranged to come into cleaning Contact with said films, a plurality of rotatably mounted unwinding reels, a plurality of rotatably mounted winding reels, and means for adjustably supporting said unwinding and winding reels so they may be adjusted laterally to bring tie films into contact with different portions of said cleaner structure.

3. A film renovating machine comprising a general framework, a cleaning structure of width to accommodate a plurality of films and arranged to come into cleaning contact with such films, a plurality of rotatably mounted unwinding reels, regulable means for each unwinding reel to retard its free rotary movement, a plurality of rotatably mounted winding reels, means for imparting rotation to said Winding reels, and means for adjustably supporting said unwinding and winding reels so they may be adjusted'laterally to bring the film into contact with different portions of said cleaner structure.

In testimony whereof l affix my signature in presence of two witnesses.
