LEONARD S. BALUTA, OF BERWIOK, PENNSYLVANIA.

REEL.

' 7 Application filed July 19,

To all whom it may concern:

Be it known that I, LEONARD S. BALUTA, a citizen of the United States, residing at Berwick, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Reels, of which the following is a specification.

This invention relates to motion picture film reels and attachments therefor, and is an improvement of my Letters Patent #1,232,753 issued to me July 10, 1917, and on of the prime objects of the present invention is to provide an improved reel embodying a novel type of hub and flanges, whereby the film can be readily and quickly irrespective of the posi- Another pri e object of the invention is to provide an proved means of forming the hub for recei ing and holding the flexible element carry'i g the film clasp whereby the same will be against displacement and eliminate the necessity of providing any extraneous means for attaching the flexible element to the hub.

A further prime object of the invention is to provide a reel including side flanges having relatively large symmetrically arranged openings stamped therein for permitting the easy insertion of the operators hand in the reel, and to lighten the weight of the reel to permit the easy handling and shipping thereof, and a novel hub structure formed from a pair of sections, which can be struck with a single stamping operation from the portions of the metal struck from the flanges to form the openings therein.

A further object of the invention is to pro vide a novel two part reel hub having means formed thereon for spacing the parts or sec. tions to form a pair of diametrically opposed key ways, the meeting faces of the sections having struck out tongues for engaging the flexible clamp carrying element to hold the same in position, the sections also having openings for receiving the tongues so as to prevent the slipping of the flexible element from off of the tongues.

A further object of the invention is to provide an improved means for forming the hub sections so as to permit the film clasp to lie flush with the periphery thereof, and thus eliminate all projecting portions on the hub which would tend to bulge the various convolutions of the film. I

A further object of the invention is to ifectively held in position v 1920. Serial No. 397,294.

i provide an improved means for attaching the film to the reel, which means permits the use of a relatively short flexible element carrying the spring clasp which eliminates the necessity of coiling the flexible element around the hub a number of times.

A still further object of the invention is to provide an improved moving picture film reel of the above character, which is durable and eflicient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, forming a part of this specification, in which drawings:

Figure l is a side elevation of the improved reel.

Figure 2 is a diametric section through the same showing the method pursued in attaching the film end to the film clamp car ried by the flexible element.

Figure 3 is an enlarged vertical section through the reel and hub illustrating the means for attaching'the flexible element carrying the film clamp to the hub.

Figure 4 is a simllar view of the flexible element and film coiled around the hub and illustrating the position'of the film receiving clasp when the same is in operative position. .t

Figure 5 is an enlarged sectional view through the improved clasp usedin connection withthe reel.

Figure 6 is an enlarged transverse sectional view through the clasp.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved reel, which includes the side flanges B and the hub C, and D designates the attaching means for the film E.

The reel flanges B are of disc like configuration and are preferably; formed of sheet metal and are provided on opposite sides of the axial center thereof with diametrically opposed relatively large openings 10. The

openings 10 are of substantially rectangular to permit the easy handlin thereof. The metal taken ings 10 is utilized to form the hub C w ich will be hereinafter more fully described. It thus can be seen that all of the metal is utilized thereby eliminating all waste of material. The side flanges B are otherwise formed similar to the usual flanges of a motion picture reel.

The hub C of the reel A is preferably formed of two companion sections 11 and 12 which as stated, are formed from the metal taken from the openings 10. This metal is stamped to provide a body portion 13 and arcuately curved flanges 14. The terminals of the flanges 14 are bent inwardly toward each other as at 15. This provides a space 16 intermediate the flanges the purpose of which will be hereinafter more fully described. The body portions 13 of the hub? sections 11 and-12 are adapted to be posi-f tioned in arallel relation to each other and are provided with pairs of struck in tits 1'? which space the body portions 13 soas to provide diametrically opposed keyways 18 on the opposite sides of the semi-cylindrical barrels 19 which provides the 0 ening for receiving the supporting shaft Fnqt shown). The opposite ends of the body portions 13 are provided with outwardly extending lugs 20 which are adapted to fit in T-shaped openings 21 formed in the side flanges B at the axial center thereof. If so desired these lugs may be upset, so as to hold the hub sections and guide flanges in correct relation. However, the arcuate flanges 14 are also provided with outwardly extending bendable tongues 22 which are inserted through openings 23 formed in the side flanges. After the tongues 22 have been inserted in the openings 23 the same are bent over as clearly shown in Figures 1 and 2 of the drawings.

The hub sections 11 and 12 are adapted to 1 receive between the body portions 13 thereof the flexible strip or tape 25 which 'formsa portion of the film holding member D which will be hereinafter more fully described. To hold the inner end of the flexible tape or strip-25 between the body portion 13 of the hub sections 11 and 12, the hub sections are provided with struck out right angularly extending pointed penetrating tongues 26 which are adapted to extend through the flexible tape or strip 25. The body portion 13 of the hub section which is not provided with the struck out prongs is provided with openings 27, which are adapted to receive the tongues so as to prevent displacement of the flexible strip or tape therefrom.

The film. holding device D is similar to the device shown in my prior patent with the exception that the flexible tape 25 is formed shorter so that the ing the same around the hub a number of and shipping om the 0 en-.

necessity of coilthe film clasp 29 is drawn through one of the openings 10 with the inner end of the film E as clearly shown in Figure 2 of the drawings. -This permits the convenient at- Q taching of the inner end of the film to the clasp. The clasp is also of novel construction and as shown is of S-shaped configuration and includes the body portion 30 and the folded spring tongues 31 and 32. The spring tongues 31 and 32 engage the opposite faces of the body plate 30 and are formed by bending the opposite. end of the plate=back upon itself. The free terminals of the spring tongues 31 and 32 are bent outwardly. as'at 33 and provided with a plurality of equi-distantly spaced prongs 34 which are adaptedto engage in the usual openings formed in the side of the film. The

prongs 34 formed one of the gripping mem-- bers for the film. The body portion 30 of the clasp is provided with a longitudinally extending slot 35 and each of the spring tongues 31 and 32 are provided with struck in longitudinally extending ears 36 which are adapted to lie within the slot. ne of the longitudinal erlges'of the. body plate 30 is provided with a pair of outwardly extending prongs 36' which-form the second means for engagingthe film to prevent the displacement thereof. These prongs 36' are also adapted to engage in the film open ing. The opposite 'edge of the body plate 30 isprovided with an extension 37 which is provided with an opening 38 and this slot is adapted to receive the folded end *39 of the flexible strip or ribbon 25. The folded end of the flexible strip or ribbon is sewed or otherwise. secured together. the end of the film in position on the clasp. one end of the same is slid between one of In placing the flexible wings or tongues 31 and 32 and and thus form a third means for preventing the disengagement of the film end from "the clamp. The clasp 29 is formed alike on opposite sides and thus the same is reversible and permits the film to be wound in either direction upon the hub. The space 16 between the wings 15 is adapted to re ceive the clasp 29 so that the same can lie flush with the periphery of the hub. This is an important feature, as all protruding parts on the hub are eliminated and the film is permitted to be evenly wound on the hub without any bulges therein.

The film reel is adapted to be placed upon the market with the film attaching member D secured thereto and it can be seen that the convenient means of attaching the film end thereto will readily appeal to moving picture machine operators as considerable time and labor will be saved in attaching the film thereto. The cheapness of construction of the reel will also appeal to a manufacturer as the same can be placed upon the market at a slight cost and still leave a good margin of profit.
