j UNITED STATES ATE NT "OFFICE This invention relates to reels, and its general object is to provide a reel that is primarily designed for use with moving picture 'film, or other Q strip-material such as tape or the'like, andwhich includes means for attaching the end of, the film 1 to the hub of the reel in a manner whereby the 'A further object is to providea reel including a film holding device which makes it p'ossibleto attach the film to the hub instantly, and? without r: bending the end of the film as is necessaryv in the filmwill be held against casual removal or.,dis

placement while winding yet will become automatically released when unwound and without breakage to the film.

use of ordinary reels of this character, therefore breaking or otherwise damaging the film when being. applied or becoming detached from my reel is practically impossible.

"Another object is to provide a film holding-fle vice that can be applied to reels now in general 'use without any material change to the structure thereof, or the die set-up of stamping machines or the like used in manufacturing the same.

A still further object is to provide a reel in cluding a holding device of the character set forth,

that is simple in construction, inexpensive to manufacture, and extremely efiicient in operation, use, and service. v

This invention also consists in certain other features of construction and in'the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accom- ,panying drawing and specifically pointed out in the appended claims. u

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a sectional view taken approxi-, mately online l,-| of Figure 2, looking in the direction of the arrows.

Figure 2 is a sectional view taken approximately on linev 2-7. of Figure 1, looking in the direction of the arrows. 1 I

Figure 3 is a fragmentary vertical sectional view illustrating the film attached to the reel and the position assumed by the holding device immediately upon movement of the reelfor winding the film thereon. j 1

Figure 4 is a sectional view taken approximately on line 44 of Figure 3, looking in the direction of the arrows. v

Figure 5 is aperspective view of'a modified form of my holding device.

Referring to the drawing in detail, thereerin,fextending throughout'its width for the purtherein. I

*ture of my reel lies in the film holding device ence numeral 1 indicates the side plates or disks 'of the, reel and which .are, secured together in reel formation by a hollowcylindrical hub 2 having a relatively wide axially arranged slot 3 therepose of receiving the end of "the strip material therein, such as the film A as shown, the film being provided with the usual perforations B Fromv the foregoing, it will be apparent that m the reel structure is substantially identical to that of reels now in general use, with the single exceptionfithat the slot 3 is'wider than the usual film receiving slots. However, the important feawhich isin the form of a toggle including a flat leveri preferably of a width substantiallyco-exa tensive. with that of the hub'and one edge portion of thefllever is rolled uponitself about, a pivot pin 5 to. provide trunnions mounted in bearing open q ings in' the disks'l, for rocking movement of the device from one side edge of the-slot to the oppo-' site side'edge as will be apparent upon inspection of. Figures 2 and 3;

Secured to the opposite or outer edge portion of the lever dis a wing member 6 that includes a central arcuate portion merging into outwardly flared curved wings I, the "wing member'being fixedto the lever 4 midway its ends as shown, and

the arcuateportion is provided with openings for 30 the passage of perforation receiving studs 8 formed on the outer edge of the lever which is of a length so that the studs project 'a suitable distance beyond the slot 3 for disposal in the-path 1 of the perforations B when the end of the film' is inserted in the slot, as shown in Figure 3.

In the :use of my reel for moving picture film,

it will. be obvious that the-reel is applied to the engagement with oneedge ofthe slot, asshown in Figure 3, from which it will be readily seen that thestuds hold the :film'against casual re 50 moval or displacement from the holding means, but when thefilm is unwound, it will be instantly released from'the studs and without possibility of breakage or damage to the film.

While I have illustrated a holding device that 5 number may be employed, it depending of course upon the character of the material for which the reel, is to be used, that is the number of perforations in the material. Again, the wings may be of a length to engage the inner surface of the hub so as to clamp the material between the edges of the Wings, and the hub, as will be apparent. That feature is important, in the event the material is very thin and unperforated.

In Figure 5 I have illustrated a modified'form of my device that is made from a single blank of material shaped to provide a wing member having arms 9 formed on' and extending centrally at right angles from the sides of the arcuate portion in for disposal in parallelism with each other between the wings H, and extending through the outer ends of the arms 9 is a pivot pin l2 to be mounted in the side plates or disks I of the reel for positioning this form of the device with respect to the slot 3 in the same manner as that of the form of Figures 1 to 4. The perforation receiving studs of the form of Figure 5 are struck from the arcuate portion thereof as shown, and are indicated by the reference. numeral i3.

It will be obvious that the form of Figure 5 is capable of performing all the functions of the other form, but will make is possible to manuiacture the device by a simplified and inexpensive method, as the blanks can be stamped from a invention will be readily apparent.

It is to be understood that changesmay be made in the construction and in, the combination and arrangement. of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is I l. A reel comprising sides, a hub secured to said sides and having a slot therein for the pasincludes a pair of studs, only one stud or any sage of one end of perforated material to be wound upon the reel, means pivotally mounted within the hub and including studs projecting through said slot to be received in the perforations of the material for releasably attaching said end of the material with respect to the hub.

2. A reel comprising sides, a hub secured to said sides and having a slot therein for the passage of an end of perforated material to be wound upon the reel, a lever pivotally mounted within the hub, a winged member secured to the lever to be carried thereby for movement across the slot and having the wings thereof arranged in the path of said end of the material, and studs on said winged member and receivable in the perforations of said material.

3. A reel comprising sides, a hub secured to said sides and having a slot therein for the passage of an end of perforated material to be Wound upon the reel, a lever pivotally mounted within the hub, a winged member including an arcuate central portion secured to the lever to be carried thereby for movement across the slot and the wings thereof being outwardly flared in curved formation from the arcuate portion for disposal in the path of said end of the material and studs on said arcuate portion and extending through the slot to be received in the perforations of said material.

4. A reel comprising sides, a hub secured to.

said sides and having a'slot therein for the passage of an end of perforated material to be wound upon the reel, means'pivotally mounted in the hub for releasably attaching said end of the material with respect to the hub and being formed from a single blank of material shaped to provide a winged member, arms formed on the sides of the winged member, a pivot pin extending.
