MOVING-PICTURE MACHINE.

Application filed January 15, 1912.

To all whom it may concern: 7

Be it known that I, TOMAS Pnoc'ron HALL, of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Moving-Picture Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an apparatus for projecting moving pictures without the objectionable flickering action and has for its object to provide a simple and improved construction for machines of this type as will be seen from thefollowing description and claims.

For full comprehension, however, reference must be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate the-same parts and wherein:

Figure 1 is a plan view partly in horizontal section, of my improved apparatus, Fig. 2 is a vertical section taken on line 2-2 Fig. 1; F i gs. 3 and 4 are enlarged detail views taken a't'right angles to each other and illustrating the construction of the refleeting device included in my. invention;

and Fig. 5. is a diagrammatic perspective view ofa portion ofmdy apparatus.

My apparatus inclu es a reflecting device of particular arrangement and form where- .by the image is reflected from the film directly to the screen upon which the pictures are being projected, thereby eliminating in machines of this type, the retracting substances heretofore placed intermediate of the reflecting surface and the screen.

Referring now to the drawings the housihg is indicated at b and incloses the reels 0 and d upon which the film is wound, passing over rolls f and g mounted on opposite sides of the front aperture lb of" the housing, the

the perforations in the film and bein operative engagement with the drivin wheel i by gear wheel. 7'. The driving wheel is preferably rotated by a crank is extending outside the housing, a sprocket and chain connection Z being provided between the driying wheel and the receiving wheel d, to move the film in the usual manner.

The film is illuminated from a point -outside the housing, the light passing through the film c and double convex lens m to a reflecting device in line with the film Specification of Letters Patent.

and preferably comprising a series of mirrors n adapted to move in unison with the film when the 'achine is operating. The mirrors which a1 substantially the same size as the image upon the film are set at an angle to their carrier and together form a reflecting surface the transverse axis of which is at an angle tothe transverse axis of the film so that when they assumeia posi tion opposite the portion of the film being illuminated they are inclined away from the film with their surface disposed to defleet the illuminated image from the film to the screen at a point to one side of the film, through a second aperture 3 in the front of the housing at the side of and in a straight line with the aperture I). (see Fig. 1). The lens m may be supported in a frame 2 secu'redto one side wall of the housing and is inclined to assume a position parallel with the mirror then in line with the image being illuminated.

To insure the surface of the mirrors (which in the present instance are plane but may be convex to form mirror lenses) coming into proper position relatively to the film that is with the side lines of the mirrors parallel with the side lines of the film, I have placed each one at a slight angle to the adjoining ones as indicated in Figs. 2 and 3.

The mirrors are mounted on a wheel 0 r0- tatably supported in the center line of the apertures between the side walls of the housing and presenting near its periphery a circular angularly disposed'fiange p to which is secured a ring 9 of channel-cross-section and facing outwardly within which the mirrors are located, being held in position by lugs 1* upon the ring a and by set screws 8.

In the utilization of the wheel 0 as the carrier for the mirrors the desired inclination of the latter is obtained by inclining them inwardly in the longitudinal axial line of the wheel such position being rigidly maintained by any preferable means as by extending the base of the ring 9 and placing a packing member a between the back of the mirrors and the wall of the ring.

The radius of the Wheel 0 is preferably twice the distance between the film and the lens and the periphery of the Wheel is provided with teeth u which engage with the i the idler 9 being on the opposite side-of the wheel 2'- to that of the wheel 0.

The operation of my apparatus is as follows: The light from a: passes through the film and lens thus projecting the image from the film'to one of the inclined mirrors n the image being then deflected to one side of the film again through the lens m and through the aperture 3 to the screen, the reels, etc, 10 beingso arranged that they do not interfere with the rays, as will be clearly seen in unison with the film the movement of the former is compensated for by the movement of the latter thus when an image is projected by one of the mirrors, the image is stationary until it is gradually displaced and replaced by the image of the next portion of the film coming into the focus of the next mirror and so deflected upon the screen. Thus two partial images deflected from two adjacent mirrors combine to form a complete image upon the continuously illuminated screen.

Althou h I have described my invention as applied to a projecting apparatus it will be apparent that it may be utilized to advantage -in photographing moving objects by closing vthe aperture h, the mirrors n then reflecting the object from the exterior of the housing to a. sensitized film.

What I claim is as follows 1. In a moving picture machine, the combination with a housing, an aperture therein, and a, film adapted to pass across the aperture, of a reflecting device situated Within the housing and presenting a reflecting surface, opposite to and moving in unison with the portion of the film oppositeto the aperture, the transverse axis of. the said reflecting surface being at an angle to the trans verse axis of the film and adapted to deflect an image from the film to one side of the line of travelof the latter, and a lens between the film and the reflecting device, and adapted to be traversed by the incident and reflected rays. I I

2. In a moving picture machine, the com bination with a housing having an apertur e therein, and a film adapted to pass" across the said aperture, of a single reflectin surface comprising a revolving series 0 mirrors all similarly inclined in the longitudinal line of a common axis and adapted to deflect an image from the film to one side of the said aperture, and a lens between the film and the mirrors.
