Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed October 9, 1917. Serial No; 195,632.

To all whom it may concern:

Be it known that I, JOHN P. BURNETT, a citizen of theUnited States, and a resident of the city of Oak Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Motion-Picture-Film Magazines, of which the following is a specification.

My invention relates to improvements in motion picture film magazines, and has for its object the production of a device of this character, designed for use especially in connection with an endless lnL A further object is the production of a mavazine as mentioned, in which the film will be so handled in the magazine that cracking or tearing of the film in the withdrawal of the same from the magazine will be positively precluded.

A further object is the roduction of a film magazine, as mentione which will be of durable and economical construction and efiicient in use.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed..

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and m which,4

Figure 1 is a front elevation of a film magazine embodying the invention, a portion of the door at the front side of the ma azine being broken away and a film defecting lmember carried thereby being shown in section,

Fig. 2, a vertical transverse section of the device, and

Fig. 3, a top slan view of the device.

The preferre form of construction as illustrated in the. drawings comprises a. circular housin 4 of an interior width equal substantie ly to or slightly greater than the width of the film A to be used in connection therewith. Said housing is verticall disposed, being secured by means of suita le fastening devices 5 and 6 to a suitable support 'i'.

The rearward side of housin 4 is open. Snugly fitting in said rearwar open side of the housing is a disk 8 which is mounted for free rotary movement about an axis 9 which is carried by the supporting member 7. In order to alleviate friction, rollers orv other suitable bearing devices 9 are preferably employed in connection with disk 8. Secured to the front side of disk 8is a plurality of spaced radially extending curved valles or blades 10 adapted, when the magnzine is in use, to engage with the film introduced into the magazine and effect shifting thereof in the magazine, as will be hereinafter more fully pointed out.

Provided at' the upper side of the housing 4 is a film entrance and exit openin 11. The front side of housing4 isx provided with a door 12 secured thereto b hinges 13, a suitable lock 14 being provi ed to hold the door in closed position.

At one side of the opening 11 are provided suitable film guiding rollers 15, between which the film A is adapted to pass inimediately before entering the magazine. Arranged directly below said rollers 15 is a wing or blade 16 adapted to direct the film entering the magazine to the right of the axis of rotation of disk 8. To assist in thus directing the film, the door 12 of the magazine housing is provided at its inner side with a blade 17 which. when the door is closed, forms a continuation of the member 16.-

Vith the constructionset forth it. will be seen that as the film enters the magazine it will of its own accord fold itself in position at the right hand side of the magazine, resting partially upon the blades 10, the outer portions of the folds or convolntions of the film being adapted to rest against the inner side of the eripheral wall of the housing. The film wil-Fbe carried around in the magazine and guided out through the opening 11 over a suitable roller 18, as clearly seen in Fig. 1. As the film is fed into the magazine at the right hand side thereof, the weight of the film upon the blades 10 at that side of the magazine will gradually increase and when the weightat that side of the axis of the member 8 reaches a certain point, the weight of the film will automatically, through gravity, cause rotative shifting of the disk 8. In this rotative shifting of the disk 8. the blades l0 at the left hand side of the axis of rotation of said disk, will cause the portions or convolutions of film engaged thereby, to be carried upwardly toward the upper side of the magazine. This being so it will be seen that. the film in being withdrawn from the magazine will always be removed from the outer side or top of the pile of convolutions or folds of film. at the left hand side of the magazine. Thisl being so,no resistance whatever will 'be offered to theiuifoldinfr' film in heiligwithdrawn, Since there will be no weight whatever upon the4 uppermost convolution which is alwaysfthe one which is being unfolded and Withdrawn. The film being constantly fed into the magazine, at the right. hand side thereof. the Weight upon the blades l0 or upon the disk S will always be. increasing at the right hand side of the axis of the disk. and the film beino alwa s withdrawn from the lefthand side of tfie magazine will result in the weight upon the blades 10 to the left of the ,axis of rotation, being constantly diminished, the result being that the disk S will gradually and constantly rotate by gravity. causing rotative shifting of the disk in the magazine. as just described. By curving the blades 10, as shown. that is so thatthe convex sides ther of will be uppermosty at the right hand side of the magazine and the concave sides thereof will he uppermost at thel left hand side of the magazine. said blades will tend to shiftA the convolution's of film at. the right hand or entry side ofthe machine outwardly toward the periphery of the magazine. and will tend to a certain extent to shift the convolutions toward the center of themagazine at the other or discharge. side thereof. This will of course tend to increase the levera of the film convolutions at the entry sideof the magazine and decrease the leverage of the film com-olutions aty the other side of the magazine. thereby aiding in effecting the desired rotative shifting of the disk 8 in a clockwise direction. A

While l have illustrated and described the preferred form of constructionfor carrying my invention into effect. this is capable of variation and modification without departing from the spirit of the invention. I, therefore4` do not wish to be limited' to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come Within the scope. of the appended claims.
