METHOD OF MOTION-PICTURE PROJECTION AND APPARATUS THEREFOR.
- Original No. 1,461,133, dated July 10, 1923, Serial 1%. 558,916, filed Kiwi 1922. Application for reissue filed December 24, 1923. Serial- No. 682,539.
To all whom it may concern:
Be it known that I, THOMAS HENRY MAR- TEN, a subject of and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada,-have invented a certain new and useful Method of Motion-Picture Projection and Apparatus Therefor, described in the following specification andillustrated in the accompanying drawings, that form part of the same.
The principal object of the invention is to devise a method and apparatus which will enable the projection of a secondary picture about the main picture for the purpose of creating and maintaining a, flexible focal adjustment in the eye of the observer, such projection being accomplished in definite co-operation' with the main projector.
The principal feature of the apparatus consists in the arrangement of a pair of projecting machines and in operating both projectors from the same source of light, means being interposed in the path of the light tothe main projector adapted to periodically intercept and deflect the'rays of light and providing means for directing such deflected rays to the secondary projector and effecting the alternation of the light from a common source to project two pictures alternately on the screen. That is to say, between the intermittent projections of the 'main picture there is thrown upon the screen, by intermittent projection, a secondary picture bounding the area of the main picture %Il1ld e main picture is projected upon the screen, is thrown off by a shutter, and the secondary and framing picture is thrown on, to be followed by the main picture. By this method a condition is created by which the eye, of the observer constantly changes its focus, which is its normal function, inducing the physical sensation of depth or distance in the picture' In the drawings, Figure matic plan of a projector device arranged according to this invention.
Figure 2 is an elevational view from therear of Figure 1. In my co-pending application, Serial No. 682,538, filed December 24, 1923, I have described a method of producing an effect of the King of Great Britain,
1 is a diagram-.
visual depth in projected pictures which is accompllshed by locating upon the screen and about the main picture a secondary icture and this secondary picture creates an maintains a'flexible focal adjustment in the; eye of the observer so that'it automaticallyadjusts itself to the varying conditions of depth or distance represented in the combmed pictures and to accomplish such result requires special apparatus as two 'projections are needed and it is an important feature in connection with the projection that the operation be simplified so that there will be no need of any special skill on the part of the operator to accomplish the .desired result and so that there will be no appreciable variation that would be objectionable to the public viewing the pictures.
In the diagram illustrated in the drawings a pair of projectors 1 and 2 are arranged close together on a suitable base 3 and the axes of the lenses are aligned to project to a central point on the screen 4.
The projector 2 is shown adjustable to accommodate any slight variations and it is arranged on' a pivot 5 located centrally between the lenses of the two machines.
The source of light 6 is suitably located in Y line with the lenses of'the' projector 1, the beam preferably passing through the lenses 7 to suitably project the rays through the projector machine. I
All projecting machines are provided with On the present apparatus I provide a revolving shutter to be located between the. projector and the light source and this shutter 8 is in the form of a large disk mounted on a shaft'supported in a standard 9, the shutter being located at an angle of 45 degrees, to the axis of the beam'of light and having one side-intercepting the beam.
The shutter is formed with the openings 10 preferably three in number and between these are the blank spaces 11. The shutter is operatively connected by suitable gearing 12 to the operatlng mechanism of the projector 1 and revolves in unison with the projector recting it through the secondary projector is that the light which is otherwise inoperative in producing a picture is utilized in the secondary'machine and consequently the secondary machine being operatively connected with the main pro ector is arranged to project its picture in the alternat-' ing eriod'of the main projector.
Tl e picture used in the secondarymachine. creates more or less sub-conscious focal activity, by intermittently diverting the focus of the eye laterally ofthe main picture, the secondary picture bordering the main picture.- This secondary projection also has the effect of maintaining a practically constant lighting efl'ect on the screen, that is to say, there will: be light transmitted to the screen by either one projector or the other; In other words, when the light is cut oil from one machine it is instantaneously projected by the other though upon different areas.
In the diagram the main picture is represented on the screen tasj extending between the points 11 and the secondary'picture is a border,v picture extending from 1 to 2 and its width is variable.
It may be found desirable to utilize a secondary picture but the efl'ect of a lighted area outside.
