MOVING-PICTURE APPARATUS.

Application filed August 18, 1915.

To all whom it may concern:

Be it known that 1, Con STAN'IINE J. Go'r'rr, a citizen of the United States, residing at Jelferson Place, Tuckahoe, \Vestchester county, and State of New York, have invented new and useful Improvements in Moving- Picture Apparatus, of which the following is a specification.

This invention relates to moving picture apparatus, and in particular to an adjustable support for the picture machine proper and to film winding mechanism therefor.

It has been the practice heretofore, when supplying reels of picture films to theaters or other places where moving pictures are displayed, to furnish an extra empty reel with each full reel, the film being run during projection of the pictures from the full reel on to the empty reel and both reels being returned after being used. It has then been necessary to rewind each film from the receiving reel on to the original reel at a later time by the use of a special rewinding machine. This method of distribution entails the very considerable expense in the trade of duplicate reels, as well as the cost and labor of transporting double sets of reels and of rewinding films in the manner mentioned by the use of a separate and special machine.

It is my chief object to improve upon these conditions by providing a rewinding attachment for each moving picture machine which attachment is of such a nature that it permits the film to be run from a single original reel on to a receiving reel forming part of the attachment and then back on to the original reel, with great economy of time and labor, particularly when the play or picture exhibited is distributed on a plurality of reels.

A further object of the invention is to provide a support for the rewinding device which is adapted also to support the picture machine in a readily adjustable and yet secure manner.

To these ends, the invention consists in the combination and arrangement of parts fully set forth in the following specification and claims, and which is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a moving picture apparatus including a rewinding device constructed in accordance with the invention for accommodating six reels and Specification of Letters Patent.

Fig. 5 is a front elevation of one of the receiving reels, showing in detail the device for securing the end of a picture film thereto;

F ig. 6 is a detail perspective view of one of the extension attaching members, showing the same connected with the end of afilm, the latter being broken away; and,

Fig. 7 is a sectional view through the rewinding mechanism alone, showing the directions of movement of the different parts.

Referring to the drawings, wherein like reference numerals indicate like parts throughout, 1 and 2 respectively designate the supporting standards for the picture machine and rewinding attachment. These standards rise from the floor or other supporting surface to which each is attached by means of a base member 3. It is obvious that the upper end of the standards may be secured in like manner to theceiling in order to insure even greater stability, but this is not essential and is not illustrated in the drawings. The standard 1 consists of three sections, including a short lower section 4;, an intermediate short section 5, and a long upper section 6. A lower bearing 7, in which one end of a horizontal rewinding shaft 8 is journaled, is mounted between the adjacent ends of sections i and 5 of this stz'indard to connect the same together. Between the adjacent ends of standard sections 5 and 6, an upper bearing 9 for one end of the horizontal winding shaft 10 is mounted in like manner to interconnect these sections.

These bearings are constructed comparatively long so as to be capable of supporting and journaling the said shafts effectively even without the assistance of other bearings. Auxiliary bearings 11 and 12, however, are mounted adjustably at the opposite ends of the respective shafts 8 and 10 upon the inner ends of adjusting screws 18 and 14, which extend through threaded bushings 15 and 16 mounted in receiving openings in the standard 2. The corresponding ends of the shafts S and 10 are pointed as shown for engagement with the respective auxiliary hearings to form needle bearings. Operated handles 17 and 18 are provided upon. the outer ends of the screws 13 and 14, whereby they may be adjusted to withdraw the auxiliary bearings from the shaft ends to afford spaces therebetween for the application to or removal from the shafts of certain parts which will be described more fully hereinafter.

A supporting table 19 for the moving picture machine 20, which latter is conventionally illustrated in the drawings, is mounted horizontally upon the standards 1 and 2 above the winding shaft 10. This table extends between the standards and is provided with a vertical opening 21 for the reception of each. A securing sleeve 22 is mounted upon each standard beneath the table 19 and is secured in adjusted position upon the standard by means of a set screw 23. It is to be understood that the picture machine 20 may be mounted directly upon the table, but to permit horizontal and vertical adjustment of the same, it is preferably mounted directly upon a supporting plate 24 which is situated above the table proper and is connected therewith by means of a universal or gimbal joint 25. A vertically adjustable hand screw 26 extends through the table 19 in rear of the joint 25 and is engaged at its upper end beneath the plate 24-, whereby the plate and the machine mounted thereon may be adjusted manually.

The shafts 8 and 10 are provided at their left hand ends (Figs. 1 and 3) with power transmission means, such as for instance, the pulleys 27 and 28 and the connecting belt 29 shown in the drawings. It is obvious that any other convenient and practical means may be employed for connecting up these shafts, provided that it will cause them to rotate in the same direction at equal speeds. The lowermost driven shaft 8 is connected at its left hand end by means of a detachable joint 30 or in any other suitable manner, with the armature shaft 31 of an electric motor 32, this motor may be controlled for the purpose of starting and stopping the mechanism of the picture machine or for the regulation of speed by any suitable means (not shown). It is to be understood also, that I do not limit myself to this particular form of prime mover.

The winding shaft 10 is reduced as at at its right hand end (see Fig. 4) and is screw threaded throughout a short extent adjacent to its pointed end. A plurality of relatively movable spindles 3%, corresponding in number to the original reels 0f the picture exhibited, are mounted frictionally upon this reduced portion of the shaft and abut each other. The inner end of the innermost spindle is in frictional engagement with the shoulder provided at the juncture between the enlarged and reduced shaft portions, whereas a. friction collar 35 is provided upon the reduced shaft portion for engagement with the outer end of the outermost spindle. A tensioning nut 36 is threaded upon the extreme end of the shaft and a helical spring 37 is mounted upon the shaft in interposed relation to the said collar and nut. By adjusting the nut 86, the tension upon the spring may be regulated so as to vary the degree of friction between spindles. Tn thn instance there are six spindles, and for each spindle there is a receiving reel 38, which latter, inclusive of its integrally formed sleeve 39 is equal in length to each spindle. The receii 'ing reels are adapted to he slid on to the shaft 10 when the auxiliary bearing 12 has been removed from the shaft end to a considerable extent by means of the adjusting screw let. Owingto the fact that the outer peripheries of the spindles 84: are flush with the periphery of the enlarged shaft portion. the receiving reels may be moved along the shaft throughout the dis' tance between bearings. A set screw 39 is provided upon the sleeve 39 of each reel for use in securing the same fixedly to either the enlarged port on of the shaft of the proper spindle 34:. When the Elm pass ng from the corresponding original, reel of the picture machine is being wound upon a receiving reel, the latter will be fixedly secured to the enlarged shaft portion in alinement with the said originalv reel. On the other hand, when. the receiving reel is used for rewinding purposes, it will be secured fixedly upon the corresponding friction spindle. These receiving reels are ordinarily retained permanently upon the winding shaft and are merely adjusted in position thereon from time to time during the intervals between successive operations of the machine.

The film in the use will thus be driven positively from its original reel on to the correspond ing receiving reel. Each origii'ial reel after it has been emptied will be removed from the shaft- 41 above the machine 20 and will be inserted upon the rewinding shaft 8, upon hood.

form is mounted fixedly between the standadjustment-of the auxiliary bearing llto permit application ofthe reel to this shaft.

. That portion :of the rewinding shaft which is coextensive with the friction spindle 34 of the-winding shaft must thus be equal in diameter to the said shaft 41. T heremaining portion ofthe rewinding shaft may be constructed larger than-the first mentioned "portion, if this is found necessary to tween the winding and rewinding shafts in needle bearings 44 carried by the supporting' standards 1 and 2. Upon this shaft 43 aplurality of idlers 45aremounted. These idlers' correspond in number and'position to thefriction spindles 34 of the winding shaft,

whereby,"-when films are being rewound on 'l30'011g111fll reels'carried by the shaft 8 from the corresponding receiving reels upon the said spindles of the winding shaft-these films will pass over the respective idlers.

An upper, semi-cylin dri cal hood'46 is provided axially with respect to its outer curved wall 47 with outwardly projecting trunnions 48 upon its quadrant-shaped end walls 49,

and these trunnions are engaged within bearing recesses provided in the standards 1 and 2 above the winding shaft 10. The uppermost edge of the hood wall 47 is secured to the front edge of the table 19 by means of the hooks 50 and eyes 51 to prevent the hood from swinging normally upon its trunnions as pivots. The said hood is provided in itswall '47 with an axial slot 52 through which the film running from the original reel of the picture machine maypass to the corresponding receiving reel, which, with the other receiving reels and the shaft 10, are partially inclosed and protected by the A second, lower hood 53 of similar ards 1 and 2 adjacent to the rewinding shaft -8 to shield the same. and is provided upon each end wall with a plurality of projections 54 which are engaged within recesses in the said standards. The lower portion of its curved outerwall is hingedto the'remaining portion as at 55 in order that it may be swung upwardly into inoperative position to permit ready access to the rewinding shaft and the reels thereon from the front of the machine. A plurality of axially extending and alining-slots 56 are provided in the up per immovable portions of the said outer wall of the hood and are adapted to have the'films which are'being rewound from the fullreceiving reels on to the empty original reels upon the rewindingshaft Passed therethrough. (See Fig. 3.)

Re'ferring-to-Fig. '5 in particular, it will bexseen that a spring clip '57 is provided -&POI 1- the -hub o'f-"ea'ch receivingreel 38 for great.

the attachment of film ends "thereto. The end of afilm may bewedged betweenthe clip and the hub conveniently and will be retained effectively therebetween under nor- .mal conditions. \Vhen, however, during unwinding of a film from the receiving reel on to .a reel carried by the rewinding shaft, the said film end will bevwithdrawn from engagement with the clip automatically at the end of the rewinding operation when the tension upon the film has become sufiiciently In Fig. 5, a'film end is not shown directly connected with the clip, but an extension member 58 which is preferaltily in the form of a comparatively thin strip of leather or other soft andpliable material, is connected at one end with the film end as at 59 and has its opposite end connected directly with the clip. This extension member is to be used in easeof an emergency. as for instance when a film has become broken and is unduly short. As shown particularly in Fig. 6, this end 590 i the extension member is provided preferably with a pair of superimposed rubber lips 60 between which the film end is adapted to be engaged. Snap fasteners 61 are provided upon the lips at opposite sides of the space for the film end and when fastened, will secure the film effectively to the said member. A number of these extension members of different lengths maybe kept with each machine for use when necessary.

The operation of the apparatus will now be described. During rotation of the shafts 8 and '10. in clock-wise direction for in stance (Fig. the films from the original reels will be wound successively from the picture machine on to the respective receiv- 111g reels carried by shaft 10. Each receiving reel is secured fixedly to the shaft 10 inahnement with the operative original reel priorto running the film from the latter After through the projecting apparatus.

each receiving reel has been filled, the set screw which secures the same to the winding shaft is released and the reel is shifted to the right (Fig. '1) and is secured by means of the said set screw to the corresponding friction spindle Until all but the last film has been run the rewinding shaft 8,

between spindles and between the latter and the supporting shaft.

Now, when all-but-thelast original reel "have been emptied, and just beforethe last one is to'bea'un, the empty original reels are apphedto the 'rewinding shaft 8 so as to aline with the-*respective receiving reels now carried by the friction spindles therefor. The outer ends of the films carried by said receiving reels are then secured to the reels upon. shaft 8 in. the manner shown particularly in Fig. '7. During the running of the last film, which now follows, the winding and rewinding shafts will rotate in colinter-clock-wise direction (Fig. 7), whereas the receiving reels will rotate with their spindles in counter clock-wise direc tions. This is due to the fact that the original reels upon the rewinding shaft are fixed with respect thereto and that the spindles for the receiving reels upon the winding shaft are free to slip upon the last named shaft. The friction will however prevent the spindles from slipping too freely and thus prevent slack from occurring in the lilms being rewound upon the original reels.

The receiving reel for the last him alone will have to be emptied. on to the original. reel, after it has been run, by special operation of the rewinding mechanism. The rewinding of this last film will be conducted in the same manner that in which the other films were rewound, after the newly wound original reels have been removed from the rewinding shaft, or said. last film may be rewound when. ti o first film of the same or succeeding picture is being eshibited.
