To all 'whom t may concern:

Be it known that I, WILLIAM RICE, la citizen of the United States, and a resident of the cit of New York, borough of Brook- 1 n, in t e county of Kings and State of ew York, have invented a new and Improved Fireproof Film-Reel, of which the following is a full, clear, and exact description.

This invention relates to a film reel, and aims to provide a device of this nature which shall be entirely fireproof, so that no possibility of an explosion occuring in the operators booth will exist.

A further object'of this invention is the provision of a lm reel in which a may be transported and be guarded against any accident.

A still further object of the invention is the construction of a reel by means of which the end of the film may readily be attached to the securing means with which it is to be associated,

Another object of the invention is the rovision of structure incorporated in my reel which will make it possible to have free access to the interior of the reel at any time this becomes necessary. y

Reference -is'had to the accompanying drawings which illustrate one ractical embodiment of my invention, an in which- Figure 1 is a side view of my improved form of reel; Fig. 2 is a sectional view taken line 2 2 of Fig. 1; y

Fig. 3 is a sectional side view taken along line 3 3 of Fig. 4;

Fig. 4 is a plan view o the same; and Fig. 5 illustrates the core associated with my reel and the fastening means constructed in connection therewith.

In allthese `views like reference numerals designate similarvpartsfand the reference numeral 1 indicates an annular band which is provided with inward1y-extending side flanges 2. The innerfaces of the flanges 2 have associated with them guide rings '3 which are spaced therefrom andinto such spaces project the outer edges o f disks 4 forming side walls. Secured adjacent the inner edges of the disks 4 are shouldered members rinrturn conveniently secured at their outer ends to a hub 6 keyed, as indicated by the reference numeral 7, to a shaft V8.

A core, including an annular band 9 provided with suitable film-end securin means 10, is'mounted between the inner en s of the ldisks 4 and is secured in this position, serving to insurerigidity of the entire structure 'annular pocket shoulder construction of the member 5 and the shouldered lange member 11 andmay have convenientl associated with such lower ends a flat gulde ring 13 positioned within such pocket.

An openin is formed in one of the disks 4, convenient y intermediate the core member and the band 1, so that the interior of the'reel may be accessible for permitting the 'securing of the end of the film and the filmsecuring means 10. Obviously, it will be impractical to have this opening Auncovered during the operation of the machine, due to the fact that eat dan er of accidental i nition of the m woul exist and with `t is in view, I provide a pair of guides 14 between which there may be slidably mounted a door 15 provided with a finger projection 16 and a pin .17 adjacent its upper edge. A pivoted keeper 18 serves to engage the pin 17 and retain the door 15 in closed position when the same is lowered, but 1t will be noted that upon the doorbeing raised it will `be first necessary to move the keeper '18 outwardlyY so as to permit'of this operation. It will Vnow be understood that the disks 4 move with respectto the band 1, and by associating with one of the side flanges 2 a dependin lug 19, it will be obvious that I' the lug wou d strike the keeper 18, when .it ismoved outwardly so as to permitof the 1 raising and lowering of -the door 1 5, thus .preventing any movement of the shaft 8 and `its associated parts other thanV approximate] one revolution. This, ofcourse, wouldy preclude any possibility of the reel being rotated as would be necessary during the operation of a moving picture projector, and would immediately give notice to the operator of the projector that the door 15 was not closed, due to the fact that the reel tion,

would fail to operate alter making one revolution, due to the keeper engaging the lug 19.

A pair of guide strips 20, terminating at their upper ends adjacent an opening formed in the band l, are conveniently mounted within such opening on a pair of conventional film rollers 2l against which the film strip may bear without danger of mutilation. A similar pair of rollers 22 may be provided .beyond the ends of the stri-ps 20 for the sume purpose.

A second hand opening 22; is formed in the annularband l, and with a view of closing this opening. l associate, preferably with rthe upper half of my band l, a .guideway 24 in which there is sliclahlil mounted a curved strip 25 normally held, by means of u. spr-ing 26, from uncovering the hand opening 23, and a further movement of the strip 25 bcing prevented by means of a stop and pin 27 associated with the flange 2 and strip 25 respectively.

The strip 25 is provided withan opening which, when such strip isin its normal posialines `with .the opening 1in which the film rollers 21 are positioned. A .door .28 actednponfby any suitable means, such as o spring 29, serves to normally .close .the same, against whichaction, however, the door may beheld back by any means, such as a clip 30.

lt will he noted that I-may provide in the usual manner a resiliently held, oldable stop pin 31 with the outer end of thc shaft V8, which precludes any possibility of an accidental removal of the hub of such shaft; and, further, that cushions of rubber, such as'32, may 4be associated with the outer face of the flange 2 so that the same may frictionally eng vwe the inner face of a casing and thus insure against any rotational -movement .of-the ban 'It will now be seen in operation that a film may readily be inserted between the rollers .2l subsequent to the door 28 being clipped by mea-ns of the cli) 30 into itsopen position a ainst action of t ie spring 29, and thatrsuch iilm may extend between theiguide strips 20 and past the rollers 22. The .keeper 18 may now be moved back, permitting the door 15 to be raised and thus allowing the end ofthe film to be secured tothe film-engaging means 10 of the annular band 9 comprising the core.

.It will now be appreciated that thc film or reel-ma be operated by imparting power to the shaI t8, which will result. in the hub 6 and its associated disks 4, together with the Gore housed within the same, being rotated, resulting in a normal winding action. However, should the operator 'forget to close the door 15, the keeper 18 will be engaged bythe 'lug l9and operation of the machine will .be im "ossble.

hould it now occur, as is -of-ten the case, that theifilm breaks, the operator may cause burning Ti1 interior :i cessation of the power imparted t0 the shaft 8, which will result in the stopping of the rotation of the disks 4; and he may now slide the strip 25 within the guides 24 against thc action of the springr 26 so that the lowermost edge of the same will slide beyond and uncover the hand opening 23, permitting the broken ends of the film to be joined together. The action of the spring 26 will, of course, move .the strip 25 backrto its normal position, insuring afeornpletc covering'of-thc hand opening .23.

For the purpose :of shifting .the reels, it will now \be.appreciated that the film may be readily wound upon the core, and b y releasing the door 2S ffrom the clip 30 a `casing is xprovided -which will hold the film in its proper )osition at all times and prevent.any possibility of the destruction ofsuch film by accidental ignition. Also, it will be linderstood thatshould the .focus oftherays result in the ignitionofthe film duri operation, the spaced guide strips 20,v as we y .as thelm rollers 21:, will render it impossible .for 'the rt of directly .reach the the film `and that the will be smothered hy passing between the rollers 21Egudestrips-2O androllers22.

-Obvio any number of modilications may wellbe resortedto without in the least de rting from the sco .of the-claims.
