FILM PROTECTOR.

Application filed Sveutember 12, 1921. Serial No. 500,092.

To all whom it may concern:

Be it known that we, HARRY T. BROWNE and FRANoIs L. Diano, citizens of the United States, residing at Mobile, in the county of Mobile and State .of Alabama, have invented certain new and useful Improvements in Film Protectors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved protector and one object of the invention is to provide a protector lwhich may be applied to the edge portion of a. strip of moving picture film and will serve to strengthen the film and prevent its being torn while being passed through a projectingl machine or while being rewound. It very often happens that a film will be broken while being used or rewound and this causes damage to the film.

Another object of the invention is to provide a protector having a construction which will permit of its being used as a binding for the side edge portions of the strip of film and to further provide a very efficient means for connecting adjoining ends of strips of binding. l

Another object of the invention is to provide a reinforcing binding for the strip of film which is so constructed that it will not materially add to the thickness of the film and will therefore permit it to pass easily through the projecting machine.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view showing the reinforcing and protecting strip placed fiat.

Figure 2 is a plain view showing the reinforcing strip applied to a strip of film.

Figure 3 is a longitudinal sectional view taken along the line 3 3 of Fig. 2.

Figure 4 is a transverse sectional view taken along the line 4--4 of Fig. 2.

This improved reinforcing means is for use in connection with a strip of moving picture film 1 and will be in the form of binding to be applied to the side'edge portions of the strip of film.' The binding' will be formed of very light metal or any other suitable material. This binding which is indicated in general by the numeral 2 is to be folded longitudinally upon the dotted lines 3 thus providing sections 4 and 5 for extending upon opposite faces of the strip of film 1 as shown in Fig. 4 and as shown in Fig. 3. It should also be noted that this binder strip has its side portions provided with openings 6 and 7 and that the portions of the strip about the openings 7 are struck in to provide flanges 8 which will extend through the openings usually formed in the side port-ions of the film 1. The teeth of the feeding wheel `of a projecting machine can thus engage the film in the usual manner to properly feed the film through the projecting machine. The outer side portion of the binder strip 2 is elongated to provide the tongue extension 9 which terminates in a fastener .tongue 10 which is similar to the fastener tongue l1 provided at the end of the inner portion of this binder strip. At the opposite end, the

binder strip has its inner side portion provided with a tongue extension 12 which is of a length equal to that of the tongue extension 9 and this tongue extension and the end of the other side portion will be perforated as shown at 13 and 14 thus-providing slots to receive the fastener tongues l0fand 1l. It will. therefore be seen that if it is found that it is necessary to use more than on length of binder in order to bind an entire strip of film, the adjoining end portions of the two strips of binder may be spliced with the tongue extensions 9 andl 12 extending in overlapping relation and the tongues 10 and 11 extending through the slots 13 and 14 and bent over to a clamping position as shown in" Figs. 2 and 3.

This binder strip may be su lied either flat or in a folded condition. Vgiien applied to a strip of film, the binder strip is to be applied to each side of the strip of film with the openings of the film registering with the openings in the inner side portion 5 and the fianges 8 extending through `the openings in the film. When it is necessary to add additional binding strips as would be the case where the binding strips are not of the same length as the strip of film, the two sections of binding strip will be connected as previously explained. It will thus be seen that there has been rovided a de- -vice for binding and stren ening a strip of moving picture film wlnch will serve to prevent the film from being broken While being fedvthrough the projecting machine or while being rewound upon a drum.

We claim: A

1;-The combination with a strip of-moving picture film having side openings. for receiving prongs of a feeding Wheel, of binding strips .for the side portions of the film doubled longitudinally for extending upon opposite faces ofthe film and having the portions overlapping the film pro-vided With openings registering with the openings in the film, the portion of the binding stripi extending acrossone face of the picture film provided with struck-in portions forming flanges about its openings, said flanges extending through the registering openings of the film and engaging the portion of the binding fitting against the second face. of the film.

` 2. A'binding 'of the character described comprising a strip foldable longitudinally to provide side portions having openings formed therein. to register when the strip is folded, one side portion being extended be- Mimet yond the second side portion at one end and terminating in a penetrating prong, the

.binding at the opposite end having the the extended ends of connected binder strips may be ositioned inoverlapping relation and the fastener prongs passed through the slots and bent to a locking position.

3. A binder strip. for a strip of moving picture film, said binder strip being doubled longitudinally to provide side sections having openings for registering with side openings formed in a strip of picture film, one side portion being provided with flange extensions about its openings for extending through openings in a strip of picture film and engaging the second side portion of the binder strip.

lfn testimony whereof We have hereunto set our hands.
