I Application filed December 9, 1910 Serial No. 596,492.

To all whom it may concern:

Be it known that I, Crmnnns V. Foorn, a citizen of the United States, residing at Nephi city, in the county of J uab and otate of Utah, have invented certain new and useful Improvements in Electric Signaling Devices for Moving-Picture Rewinding Mechanisms, of which the following is a speci fication.

This invention relates to film rewinding or reversing mechanism for moving picture machines, and particularly to signals therefor.

One object of the invention is to socon struct a mechanism of this character that the film may be rewound r reversed at the same time that another film is being exhib-' ited, and notice of the completion ofrcwinding given to the operator.

Other objects and advantages will be apparent from-the following description when taken in connection with'the accompanying drawings. y

In the drawings: Figure 1 is a side elevation showing the apparatus as used in connection with the usual motion picture machine. Fig. 2 is a front elevation of the rewinding mechanism. Fig. 3 is a vertical sectional view on the line 33 of Fig. 2,

and Fig. 4 is a vertical sectional view on the line 1-4 of Fig. 2.

Referring to the drawings, the numeral 1 designates 'a supporting table having mounted thereonthe usual apparatus for exhibiting motion pictures which, includes upper and lower film magazines 2 and 3, and a takeup shaft 4. Leading from a pulley (not shown) on the shaft 4 is a belt 7, said belt being trained around a pulley 8 mounted on the shaft 11 which is mounted in a casing 10. One-end of this shaft carries a reel 9 on which the film is rewound. This shaft is suitably supported in bearings 12 and 25 carried by the casing 10. Suitably mounted in thecasing 10and parallel with the shaft 11 is a stub shaft 22, said stub shaft carrying the reel 23 on which is wound the film-that has been previously exhibited and which is to be wound on the reel 9.

A guide-way 33 is formed in the top of the casing 10 directly over the shaft 11, and adapted to move vertically through this guide-way is a rod 34. To the lower end of this rod is secured a yoke 35 having journaled in its ends a shaft 36, and rotatably mounted on this shaft is a rubber roller 37,

the circuit closer will benioved 11px 1 ,rr

this roller bearing on the film of the reel 9, as the film 1S. being Wound thereon. Carried upon a portion of the yoke 35 is a preys-c tion 38, said projection being .for the our- 'cator or circuit closure is adapted to travel vertically when the film is being rewound or reversed until the said yolt'e 35 reaches such position that the projection 38'will move the contact 21 into engagement with the'contact 2G to complete an electric circuit, in whichis included a suitable filflffl'l. Ar ranged intermediate the

reels

9 and 23 are guide rollers 40 and 41, said rollers guiding the film from one'reel to the other.

In operation, the film having been wound by the exhibiting machine, this reel or liini is placed in the casing 10 upon the shaft 522. The end of the film is then passed over the roller 41 and under the roller 4G and cured to the hub of the reel 9 by a sui'tal clip. The proper clutch (not shown; he

thrown into locking position, and upon t operation of the usual projectin a nism, motion is imparted from the pulley, carried by the takeup shaft tl'irou i the belt, which in turns rotates the sin iii, thereby rewinding or reversing the same time that another film is sci hibited. As the film winds upon t-h 38 forces the oontdct 21 into engag, with the contact- 20. The circuit wili ti be closed and the signal sounded so that operator will know that the film reel has been transferred to the reel 9, whereupon he disengages the mechanism from the exhibiting machine.

What is claimed is:
