PORTABLE MOVING-PICTURE MACHINE.

Specification of Letters Patent.

Patented Oct. 8, 1918.

To all whom it may concern:

Be it known that I, FREDERICK C. TAY- LOR, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Portable Moving- Picture Machines, of whichthe following is a specification.

My invention relates in a moving picture machine to a circuit breaker to automatically cut out the motor and shut off the illumination of the machine for repairing broken film.

The nature and scope of my invention will be better understood from the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1, is a side elevational view of the portable fire-proof cabinet in an open position, showing internal mechanical and elec trical equipment, in a preferred form, and the circuit breaker of my resent invention in application and in whic the film traveling in contact therewith through the machine in case of breaking of such film of instantly the motor being stopped and the lamp extinguished; and

Fig. 2, is an enlarged view, partly in central longitudinal section and artly in elevation, of said circuit breaker evice.

Referring .to the drawings a, is a rectangular-shaped asbestos or other fire-proof material cabinet or holder for the following instrumentalities :-A feed reel 5, is operated by an electric motor 9, located in one corner of the cabinet, as shown in Fig. 1, and which will be presently more fully described. Beneath the take-up reel 6 is arranged a sprocket-wheel b Alongside this wheel and in a position adjacent thereto is arranged a friction guide-roll 5 The sprocket-wheel b and the roll 6 are supported in position above the projector-lens 0, extending from the housing 0 in which is preferably mounted a pivoted intermittently operating sprocket c and supported from said housing are respectively, a friction guide-roll 0 and opposite the same is arranged a. sprocket 0, both supported from the housing. A lamp-house d, is preferably located centrally of the cabinet a, in rear of the aperture-plate 0 carried by the projector-lens housing 0 The lamphouse (I, is provided with an incandescent or other type of electric lamp (1. arranged in the circuits 10 and 11, looped into the main line circuits 12-13 from a source of energy. not shown, and in which circuits the electric motor 1. is included. The lamphouse (I, is provided with condensing lenses (Z Below the lan'ip-house (Z. as shown in Fig. 1. considered with respect to one corher of the said house (I. is located a guide roll 0. Above the lamp-house (Z. and at the left hand corner of the cabinet a, is located the said take-up reel 5-".

The circuit breaker ll, of my invention comprises a housing [1. the roof whereof. is provided with guide-rolls 72 and k arranged at different elevations with respect to each other. The housing k carries a swinging-arm it, having a weighted roll it. at the free extremity thereof and which roll as well as the guide rolls b and b is normally in bearing contact with the traveling film 2', as clearly shown in Fig. In the housing iii. are provided binding posts it and It. in engagement with the insulating base of the housing If, and re movably secured thereto. The line wires 14. and 15 from the source of energv and in which the motor 9, and are or incandescent lamps (l of the machine are included. are connected with the posts it and h'". respectively. These posts are perforated about midway in their length, as clearly shown in Fig. 2 and through which a longitudinal circuit breaking rod If, is afforded play therein. The rod it is provided with a shoulder h and a collar iv and it carries thereon an insulating sleeve 11 A leaf spring it, projects vertically from the binding post it", and surrounds the insulating sleeve it. and bears normally against the collar 7L9. when the rod 72 is held in a slantinglv in clined position under the compression of the coiled spring it, carried on the lower end of rod 71-8 by the engagement of the shoulder 71 with the binding post 11. This spring is in bearing contact at one end against the support h. and at the opposite end against the cap it. romovablv secured to the lower extremity of said rod it lvhen a film ibreaks. the weighted swinging-arm 7:. falls contacting with the rod k which owing to its weight depresses the rod, thereby disengaging its shoulder h from the binding post h, when the sprmg It will move the said rod to the left, as shown in dotted lines in Fig. 2. This movement of the rod h disengages its collar h from the leaf spring h lVhen the rod it occupies the middle position in the openin s of the binding posts It and h, the circuits lat and 15, are broken and thereby the motor g, stopped and the lamp d cut out of the said circuits. This condition thus permits an attendant to readily repair the broken film in order to again be able to quickly manipulate the machine for its designed purpose, after restoring the weighted swinging-arm h, to the position it previously occupied, as illustrated, for example, in Fig. 2, in engaging contact with the uper surface of the film i, and with the rolls 2 and it respectively, in bearing contact with the under surface thereof.

The foregoing instrumentalities and their arrangement having been defined and described, I will now proceed to explain briefly the coursing of the non-intla1nmable or other type of film 2', from the feed reel 12, downward in a taut straight vertical inclined course around the guide roll a, then between the. switching device IL, around the sprocket c, and between it and the guide-roll 0 then between the guide-roll 0, and sprocket c and fed verti ally in front of the apertureplate 0 into a loop between the guide roll 2 and around the sprocket b and thence vertically to the take-up reel 5 whereon the non-inflammable or other type of film 2',

is wound for use again or removal from the same.

Between the respective reels 1) and b the cut-out switching device 71., automatically acts in case of the breaking down of the film 2', in its coursing to instantly stop the motor and cut oil the illumination of the machine in the manner hereinbefore explained as well as feed of the film, until the same is repaired.

The defined coursing of the said film is automatic from the feed reel 1), through the machine to the take-up reel 12 This is particularly desirable as such type of portable machine is generally operated by inexperienced persons so that in case of the breaking or tearing of the film it can be instantly repaired with the least time, trouble or expense attending the work.

Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters Patent is 1. A circuit breaker device having a base with perforated posts supported therefrom, certain of said posts constituting terminals for an electric circuit, one of said terminals provided with a leaf-spring, a rod arranged in the perforation of said posts and having means normally engaging one of said posts and carrying a spring normally held under compression, said rod having an insulating sleeve and metal collar. the latter normally contacting with said leaf-spring, a weighted movable arm normally in engaging contact with a traveling film and means in engaging contact and along which is guided said film, said weighted arm being adapted when the film breaks to drop, depressing said rod to release said spring and to disengage the collar from said leaf-spring. substantially as and for the purposes described.

2. In a circuit breaker device. an insulating base, three perforated posts supported thereon, two of which posts constitute terminals for an electric circuit, one of said terminals being provided with a leaf spring, a rod engaging said supports and passing through the perforations thereof, said rod having a shoulder normally engaging one of said posts and carrying a spring normally held under compression, said rod also having an insulating sleeve and metal collar. the latter normally contacting with said leaf-spring, and a weighted swinging-arm normally in engagingcontact with a traveling film and rolls in engaging contact and along which said film is guided, said weighted arm being adapted when the film breaks to drop, depressing said rod to release said spring and to disengage the said collar from the said leaf-spring, substantially as and for the purpose described.

In witness whereof I have hereunto set my signature in the presence of the two subscribing witnesses.

FREDERICK C. TAYLOR.
