Specification of Letters Patent.

Patented Feb. 12, 1918.

Application filed December 1 2, 1816. Serial No. 186,479.

To all whom it may concern:

Be it known that I, LANGDON MoCoRMrox, a citizen of the United States, residing at New York in the county of New York and State of Ilew York, have invented certain new and useful Improvements in Moving- Picture Apparatus, of which the following is a specification.

This invention relates to improvements in means for automatically controlling the lamps located to show light where actual light is or is intended to be shown in a picture on a screen on which moving pictures are produced.

In my allowed applications for patents, Serial Numbers 831,015, filed AprillO, 1914, 58,896. filed October 30, 1915; and 95,039, filed May 3, 1916, I have shown and described means for showing light in pictures appearing on a screen, where the representation of light is shown, My present invention has for its object to provide special means, controlled by the moving picture film for automatically and electrically controlling the lamps or other devices to cooperate with the pictures produced.

A further object ofthe invention is to utilize the feeding perforations in the film as a means for receivin the contacts to make and break circuits or controlling the lights, the contacts also serving as a means for strengthening the film edges.

A further ob ect of the invention is to provide means controlled by contacts on the moving picturefilm to openand close various battery circuits, and operate relays etc. to automatically and intermittently move a contact cylinder for throwing in selected lights or devices to be used in rendering the pictures on the screen more realistic.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims. 7

- In the drawings 1 Figure 1 is a conventional View of a moving picture machine and ascreen, to illustrate the application of my invention.-

Fig. 2 is a diagrammatic view to illustrate the various circuits.

Fig. 3 is a detail cross section of the film to illustrate one of the eyelets.

1 indicates a moving picture apparatus, 2 the moving picture film, 3 a translucent screen, and 4 a casing screen and in which the various devices operated in connection with the pictures being reproduced are located.

The usual openings 5 in the film are employed to receive the various contacts for controlling the circuits, to light the lamps and to extinguish same. Near one edge of the film and in the. openings 5 are inserted metal eyelets 6, to throw in a battery circuit to actuate a magnet, so as to light the lamps. To insure perfect contact, the eyelets are preferably arranged in groups, as shown, each group 6 of the series employed to light the lam s being arranged on opposite sides of the lm and marked reset, this term being employed in connection with these particular eyelets, as the latter in this series are used to close a circuit to reset other mechanism to be described.

Located to bear on the opposite faces of the film, and just previous to the entering of the film through the condenser, and in the path and movement of the reset eyelets 6, are curved resilient contacts 7 and 8 fixed to the frame of the moving picture apparatus as shown conventionally in dotted lines in Fig. 1. Connected to the fixed contact 7 is a wire 9, and branching therefrom is a bat tery 'Wire 10, attached to a battery 11, and from the battery extends a Wire 12, and branching therefrom is a wire 13, connected to a magnet 14, and extending from the latter is a wire 15, leading to the fixed contact 8. v I

Near the opposite edge of the film the eyelocated back of the" lets are arranged in groups 6", and are indiother to properly actuate the magnets, as

will presently appear. The eyelets extend through the openings in the film to the opposite surfaces or faces thereof to engageand coiiperate with the fixed contacts 7-8 and 1718.

Attached to the fixed contact 17, is a wire the return wire 15, to an impulse lamp 27,

wired to a switch 28, adapted to cooperate with the contact 24. The switch 28 is arranged to be used when it is desired to bring the impulse lamp 27 into' use. When the current passes through the magnet 14, the lamp is arranged to light by 9. art of the current, the other part passing t rough the magnet, it being necessary of course tov throw the switch 28 against the contact 24 when it is desired to utilize the lamp in connection with the picture produced on the screen.

The cores 14 and 21, of the magnets are spaced apart, and operating between them is a pivotally mounted armature 30, the lower end of which is divided by insula tion, indicated at 31, to form a contact surface 32. Extending from the contact surface is a battery wire 33, connected to a battery 34, and branching from the wire on the opposite side of the battery is a branch wire 35, connected to a magnet 36, and connected to a contact 37, adjacent the contact surface 32, by a return wire 38. On the opposite side of the contact surface 32, is a contact 39, connected by a wire 40, leading to a magnet 41, which is connected by a branch wire 42, with the branch wire 35 and battery 34.

The magnets 36 and 41, are spaced apart,

and operating between same is a pivoted armature 43 provided on its lower end with a pawl 44. Suitably mounted on a shaft 45 is a cylinder 46, of insulated material provided at one end with a ratchet wheel 47, with which the pawl 44 engages. The contact cylinder is provided on its periphery with properly disposed contacts 48, connected by branch' wires 49, with a battery wire 50,- and battery 51. Supported adjacent the contact cylinder on the periphery thereof are spring contacts 53, and extending from each contact is a wire 54, which leads to various devices, such as lamps, signals, etc., to be used in connection with the picture being produced on the screen. Connected to one of these wires 54 is a wire 56 connected to a magnet 57. A second magnet 58 is wired to the magnet 57 and a wire 59 extends therefrom and is connected to a return wire 60, attached to the battery wire 51.

62 indicates'an armature disposed above the magnets 57 and 58, and connected to one end is a wire 63, leading to a high tension lamp 64. Extending from the lamp is a wire 65, leading to a battery 66, from which a wire leads to a. contact 67, disposed adjacent the free end. of the armature 62. This lamp circuit is only brought into play when an exceedingly high power light is required, the battery of course being of sufiicicnt voltage to produce the desired result.

It is not deemed necessary to show all the other wires 54 connected up with devices, as they all have branches, and the return circuit asses through wire 60. It may be stated, iowevcr, that the wires 54 may be connected to motors, or other actuating de- VICQSLEIS shown in Fig. 2. For instance, a lamp circuit 70, and branches 71 are connected to one of wires 54 and the wire 60, in exactly the same manner previously described. This circuit controls a movable lamp 72, WhlCh may be moved by a motor, and drum, and cables 73, actuated by a circuit 74, controlled by a circuit through branch wires 75 and one of the wires 54. This lamp maybe revolved to give a lighthouse effect, to represent the raising or low ermg of the moon, or to give cloud eflects, fire, lightning, and such things where synchronizing with the picture is not essential.

In operation, a film is provided with as many groups of reset eyelets as it is desired to produce lights in the picture to be produced. These eyelets are of course disposed at points where the lights are necessar according to the pictures on the film, an of course the corresponding group of.

move eyelets are arranged on the films at points necessary to extinguish the lights. It may also be stated that the contacts on the insulated contact cylinder are arranged at the proper places to make the necessary circuits to light the lamps or actuate the other devices to cotiperate with the pictures being produced on the screen.

For instance, as shown in Fig. 2, but one contact is shown to engage the resilient contact 53, hence in one revolution of the contact cylinder the lamp will be lighted but once. However, if the picture bein pro duced requires the use of this light for more than one occasion other contacts will be provided. But one is shown in the drawing, and it is to be understood that this is merely illustrative, as it is evident that as many more contacts as may be necessary can grim readily supplied to suit any particular In the position shown in the diagram (Fig. 2) a group of move eyelets are shown as passing between the fixed contacts- 17 and 18, which throws in the battery 11, and energizes the magnet 21. The circuit passes through the battery wires 10, 12, to the magnet 21, and thence through the return wire 23 to the fixed contact 18. This circuit is closed just previous to the film entering the light rays of the condenser of the moving picture apparatus, with the result wire 33, connected to the armature 30.

When the magnet 36 is energized, the armature 43 is attracted, and the movement pulls on the awl 43, the contact cylinder is turned, whic of course shifts the position of the various contacts 48. In the instance shown, one of the resilient contacts 53 is positioned to be in circuit with a contact 48. v

The circuits just described are for the purpose of changing the light or lights behind the screen, as will be understood.

Now let it be assumed that the reset eyelets 6" come between the fixed contacts 7 and 8. The circuit is closed through wires 9 and 10, battery 11, wires 12 and 13, to magnet 14, and returns through wire 15. The magnet 14 is thus energized, and the armature 30 is attracted, this circuit is closed through the same battery 11, used in closing the circuit previously described.

Immediately the armature 30 engages the contact 39, a circuit is established through wire 33, battery 34, branch wire 42, magnet 41, and return wire 40, with the result that the magnet is energized and the armature 43 is attracted. This movement of the armature causes the pawl 44 to ride over the ratchet wheel 47, to a new position for a subsequent operation, hence the reset eyelet contacts reset the contact cylinder operating means, and establish a circuit to cause the circuit to lamp 64, to be established, and of course any other lamp or devices connected to the wires 54 to be lighted or operated as the case may be.

When the contact cylinder is set as shown in the drawings, current is established through battery 51, wire 50, contacts 48 and 53, wires 54and 56, magnets 57 and 58, wires 59 and 60. When the magnets 57 and 58 are energized the armature 62 is attracted, and it engages contact 67, and through battery 66, lights the lamp 64, located immediately behind the screen to register with some feature in the picture requiring actual light, as described in my before mentioned application. (lf course if the lamps are to be wired to move with the successive pictures, a motor or other means will be actuated by the closing of a circuit through one of the wires 54. I

The battery: 66 is much stronger than battery 51, to produce a light of sufiicient candle power to accomplish the desired result, each battery being of the proper size to operate the 'lamp or other device to be brought into use.

position until a. eyelets interrupt the cir- The parts remain in this group of move cuit.

During the period that the reset eyelets are in circuit, and every time one of sad eyelets passes between the contacts, and switch 28 is properly set, the current imparts an impulse current through the wires 24 and 26, and the impulse lamp 27 flickers, this being due to the fact that this lamp is connected in parallel with the reset circuit. T hls, of course, is only an illustration of the possibilities of the application of the invention, this lamp being used in connectlon with a moving picture machine where it s necessary to produce actual light or a series of actual lights on a screen. The

lamps may be arranged behind the screenin groups, or placed in accordance with'the spots on the picture where light or lights are to appear, and the contacts and the wires 54 can be so arranged to obtain, absolute registration with the pictures.

The eyelets, in addition to being employed as contacts, are eflective in strengthening the edges of the film, and since the feed wheels engage them, it is obvious a magnets with an armature between, one
