PHOTOGRAPHIC FILM REEL Feb. 28, 1933.

Patented Feb. 28, 1933 UNITED STATES PATENT; OFFICE 1 LEW W. LESSLEB, OF JOHNSON CITY, NEW YORK, ASST GNORQQQAGFA ANSCO CORPORA- TION, O1 BINGHAMTON, NEW YORK, A CORPORATIONOF. NEW YORK PHOTOGRAPHIC FILM REEL Application filed. March 12, 1931. Serial No. 522,008.

My invention relates to reels for motion picture films and the like.

Cine film reels such. as are used in motion picture cameras and projectors are usually provided with slotted cores, recessed portions in such cores with cross pins therein, or other contrivances adapted to secure one end of the film thereto for winding same thereupon. Such means of attachment necessitate the folding or creasing of the extreme end of the film prior to its introduction into the slot or its being folded over the cross pins etc. and this method of attachment is generally unsatisfactory in that it requires considerable time and is not always positive in action. In addition to this, after winding, or

unwinding the film on the reel several times the creased brittle end becomes cracked or torn thus requiring the user to fold over a new portion of the film. Such methods of attachment prove even more objectionable on the small 16 m. m. size reels now being extensively used by amateur movie enthusiasts, wherein the flanges of such reels are spaced so closely together asrto make it extremely difficult for the user to manipulate the folded end into the slot in the core or over the cross pin thereof.

- The primary object of my invention 1s to provide an attachin means on the core of the reel which will e ectually secure the film thereto and allow its easy and quick removal therefrom when desired, without'requiring the folding, bending or unnecessary handling of same and which facilitates and expedites such operations of attaching or detaching the film thereto or therefrom.

Another object of my invention lies in the provision of a reel comprised of few parts adapted to be easily assembled and economic of manufacture.

Other objects and advantages in details of construction'and arrangement of parts will be apparent as the description proceeds. reference now being had to the figures of the accompanying drawing, forming a part of this application and wherein like reference numerals indicate like parts.-

In the drawing:

Figure 1 is a side view of my improved film reel, certain parts being broken away for clearness.

Figure 2 is an edge view thereof.

Figure 3 is a detail side view of the core portion of a modified form of my invention.

Figure 4 is an edge view thereof.

Figure 5 is a side view of another modification ofmy invention.

Figure 6 is an edge view thereof.

The reference numeral 1 refers to a cylindrical core preferably formed of metal provided at spaced intervals along the edges thereof with outwardly extending lugs 2 adapted to be passed through suitable openings provided in disc flanges 3 and l disposed on either end of the core, and'headed over such openings as at 5 to thus rigidly secure the flanges 3 and 4 thereto and in parallel relation.

The flanges 3 and 4 are stamped or otherwise suitably formed of metal or other suitable material and. are preferably made with a plurality of holes or openings 6 therein to further lighten the weight thereof and are provided centrally thereof with square axial openings 7 for the purpose of mounting the reel on the shafts of the camera or projector in which it is to be used. The spacing between the flanges 3 and 4 is dictated by the width of the film to be used in connection therewith.

'It will be noted with particular reference to Figure 1 that the ends of the material of the cylindrical core 1 terminate with a slight space therebetween, the purpose of which, is to permit the ends of a strip of relatively thin metal stock 9 of a width substantially that of the core 9, to be snugly coiled about the core 1 and to be passed therethrough and 12. It will be observed with particular reference to Figure 2, that these lugs 11 and 12 are struck from the strip 9 precisely in alignment with the usual standard perforations 13 of the film 8 whereby same may be quickl easily and securely hooked thereon for win ing. The alternate direction of the hooks 11 and 12 serves to permit the film to be hooked in either direction so that the film may be reeled thereon in a clockwise or a counter clockwise direction, circumstances dictating such directions. It may be stated that there is an inherenttendency for film to curl slightly at the end thereof as shown in Figure l and it is an easy matter for the user to insert the end of the film between the flanges 3 and 4, and without attempting to guide it other than into contact withthe core 9, to draw it over the lugs 11 and 12 until one of the perforations thereof engages with one of the lugs 11 or 12. This, of course, secures the end to the core to permit winding the film thereon.

Referring now to Figure 3, the construction of the core 1 and flanges 3 and 4 is substantially the same as described in the foregoing, the change being in the substitution of two clip members herein indicated at 14 of m invention. I do not limit 111 self, there ore, to the exact form herein s own and described other than by the appended claims.

I claim:

1. A reel for motion picture film comprising a core havin spaced flanges secured thereto the ends 0 said core terminating in spaced relation to provide a single slot, and hooks provided on the ends of said core adjacent each of said flanges'and in alignment with the perforations in a film to be Wound on said core, the hooks on one end extending in one direction and those on the other end extending in the opposite direction.

2. A reel for'motion picture film comprising a cylindrical core of sheet metal having spaced flanges secured thereto, the ends of said core terminating in spaced relation, clip members adapted to be clipped over said ends, the extreme outer ends of said clip members being rovided each with a pair of spaced paral e1 angularly disposed upstanding lugs in alignment with the perforations of a. film to be wound on said core.

In testimony whereof, I afiix my signature.

LEW W. LESSLER.

and 15 for the strip 9 of the preferred em bodiment of my invention. These members 14 and 15 are preferably formed of relatively thin sheet material and are adapted to be secured to the core 1 as by securely clipping same in opposite directions over the spaced ends of such core. end of these members 1 1 and 15 are provided each with a pair of suitably spaced parallel angularly upstanding lugs 16 and 17 respectively. The purpose of such lugs of course, corresponds to that of the lugs 11 and 12 of the preferred form, the difference being, that in using this form of construction two perforations of the film will besimultaneously engaged within lugs 16 and 17 instead of one as in the first case.

The reel disclosed in Figures 5 and 6 is of a relatively much smaller size than the two previously described reels and therefore permits the use of relatively much lighter stock in the manufacturing of same. It is obvious, therefore, that the core la thereof may serve the additional purposeof providing the film engaging lugs 16a and 17a. These lugs 16a and 17a are stamped integrally with the ends of the core 1a and are adapted to be bent upwardly and back at an angle as clearly shown in Figure 5. The flanges 3a and 4a of this form of my invention are secured to the core 1a as by means of the ears 5a of said core passing through slots provided in said flanges therefor and bent outwardly thereover.

Of course changes may be made in details of construction and arrangement of parts without departing from the spirit and scope The outer and extreme
