UNITED STATES EDMOND JOHN ROY, OF NEW YORK, N. Y.

IOVIIl'G-PICTURE MACHINE.

Application filed June 10,

The present invention relates to improvements in-moving picture machines, and has reference more particularly to an improved projection apparatus.

One of the important objects of the present invention is to provide a projection apparatus, wherein the usual shutter mechanism is eliminated, means being provided for intermittently turning on and off the source of illumination which is associated with the projection apparatus.

Another important object of the invention is to provide a moving picture machine wherein a 'circuit maker and breaker is provided for periodically operating the source of illumination provided for the projection apparatus, the mounting for the circuit maker and breaker, being readily and easily attached on the projection apparatus without necessitating any material alterations.

A further object of the invention is to provide a moving picture projection apparatus of the above mentioned character, which is simple in construction, inexpensive, and furthermore adapted to the purposes for which the same is designed.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accom anying drawing forming part of this speclfication and in which like numerals are employed to designate like parts throu hout the same:

Figure 1 1s a side elevation of the circuit maker and breaker embodying my invention, showingthe same attached on a projection apparatus of a moving picture machine,

igure 2 is a top plan view thereofyand Figure 3 is a side elevation showin the supportingmeans for the source of i1 umination.

In the drawing, wherein for the purpose of illustration is shown the vpreferred embodiment of my invention, the numeral 1 designates generally the picture projection appaartus of a moving picture machine, the same being of the conventional construction,

' with the exception that the shutter and the supporting mechanism therefor is removed. The source of illumination which is associated with the picture projection apparatus, in the present instance, comprises an electric lamp 2,.which is supported in a suit- I able socket 3 and for the purpose of supporting the source of illumination directly in rear of the-usual lenses arranged within 1926. Serial No. 115,027.

the pro'ection apparatus, there is provideda pan- 0 supporting arms 4 and '5, respectlV8lV.' The arm 4 is secured at its upper end to the side of the cylindrical housing :6 provided for the lenses, not shown, the securing means bein shown at 7. The forward end of the horizontally disposed arm.

5 is secured to the lower end of the arm 4 as at 8, and. the rear end of the horizontally disposed supporting arm 5'is secured to the vertical portion of the angular bracket 9, which bracket is rigidly secured to the side of the socket 3 prov1ded for the electric lamp 2. This construction is more clearly illustrated in Figure 3 of the drawing. A fly wheel .10 is supported on the outer end of the shaft 11 which forms a art of the picture strip feed mechanism of the projection apparatus, and which shaft is ada ted to be actuated by the usual gearing esignated generally by the numeral 12 in the manner well known in the art. Carried on the outer face of the fly wheel 10 is the insulator disc 13, the same being preferably formed of fiber, although any other suitable insulated material may be employed. The outer face of the insulator disc 13 is cut out to accommodate the opposed segmental contact plates 14 and the outer faces of these contact plates lie flush with the outer face of the insulator disc 13 in the manner as clearly shown in Figure 2. The purpose of the segmental contacts 14 will be hereinafter more fully described. Y

Cooperating with the se ental contact plates 14 are the outer en s of a pair of brushes 15 and 16, respectively. These brushes are formed of spring metal, and the outer ends thereof are curved as clearly shown at 17, in Figure 2 so that the same may ride. freely over the outer face .of the insulator disc 13 and the segmental contact plates 14. The rear ends of the brushes 15 and 16 are secured to an insulated block18 and the securing means for the brushes provide terminals and are designated by the

numerals

19 and 20, respectively. One of the terminals is connected .to the source of supply 21, through the medium of the wire 22, while the other terminal is connected to the electric lamp socket by the wire 23in the manner well known in the art. Current is supplied from the'source 21 to the lamp 2,

through the medium of the wire 24.

The insulated block 18 which carries the spaced brushes 15 and 16 is secured on the forward lower end of a supporting arm 25. The opposite end of this arm is detachably supported on the outer end of the transversely extending bolt 26. The outer end of this bolt is theade'd and a pair of lock nuts 27 are threaded thereon and are arranged on opposite sides of the upper rear end of the arm 25 in the manner as clearly shown in Figure 2. The inner end of this bolt 26 extends through a longitudinally extending slot 28 formed in the elongated strip 29 and is adjustably secured in the slot 28 by means of a pair of lock nuts 30 which are arranged on opposite sides of the strip 29, it being understood, of course, that the inner end of the bolt is also threaded.

The lower end of the strip 29 is pivotally secured to the rear end of a similar strip 31 as at 32. This strip 31 is also provided with a longitudinally extending slot as at 33 and a pair of screw members 34 extend throu h the slot 33 into the side of the frame of t e projection apparatus 1. These screws 34 cooperate with the slot 33 in securing the horizontal strip 31 in any adjusted position. The provision of a supporting means for the brush carrying block, permits the brushes to be adjusted to any desired position with respect to the disc 13 and the segmental contact plates 14 carried thereby.

The projection apparatus 1 is operated in the usual manner, and it is readily obvious that as the shaft 11 rotates, the fly wheel 10 will rotate therewith and also cause the simultaneous rotation of the disc 13. The

outer ends of the brushes 15 and 16 will co-v the moving picture strip which is fed through the machine will be in no way affected.

The simplicity in which my improved circuit maker and breaker is constructed enables the same to be readily and easily attached to the projection apparatus of machines of any well known construction without necessitating any material alterations of the parts of the machine with which the device is associated.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit and sacrificing any of the advantages of the appended claim.

Having thus described my invention, what I claim as new is:

In combination, a shutterless moving picture projection apparatus, a source of illumination associated therewith, means for intermittently turning on and off said source of illumination, said means comprising a rotatable insulator disc mounted on the projection apparatus, spaced contacts arranged in the outer face of the insulator disc, brushes engaging the outer face of the disc and said contacts, supporting means for said brushes, said supporting means comprising an insulated block on which the inner ends of the brushes are secured, an arm car ing said block, and additional means for ad ustablymounting the arm on the projection apparatus, the last mentioned means comprising a pair of members having theiradjacent ends pivotally secured, one of said members being secured on the projection apparatus, a bolt extending transversely from the other member, the outer end of said bolt extending through said arm.

In testimony whereof I aflix my signature.

EDMOND JOHN ROY.
