785,205 flame-shield 40. it is supported in any suitable manner, as b.y the screws 41, from any portion of the apparatus. Like the similar shield 30, it may be of any desired shape and 5 any non-inflammable material provided it presents a proper obstacle to the upward passage of the flames between the shutter 15 and the support 10. When these shields SO and 40 have been put in position and the heat-rays from the io lantern are permitted to impinge upon the film 20, the latter catches on lire and the flames spread upward to the front and rear; but their passage is checked by the shields and the fire dies out. It is impossible for it to follow the 15 Him upward between the shutter 15 and the diaphragm back of it for lack of air, and of course it cannot retreat downward. The result is that a hole is merely burned in the film, and the machine being again put into motion 20 the exhibition can be continued uninterruptedly, the film itself can subsequently be pieced, and the burned spot cut out. If there existed a danger -spot similar to that at the lightaperture, it could be similarly protected by 25 one or more flame-shields. Having described my invention, what I claim as new is — 1. A moving-picture apparatus or the like, provided with a flame-shield comprisi ng a sub 30 stantially horizontal plate extending at an angle with the film and provided with one or more depending flanges, the whole placed above the danger-point and in close proximity thereto. 2. The combination with a kinetoscope comprising a film-propelling mechanism of a plurality of flame-shields placed in close proximity to the path of the film and extending o u tward ly there from . 3. The combination with a kinetoscone comprising a film-propelling mechanism of a plurality of flame-shields placed in close proximity to the path of the film and extending outwardly therefrom, one of said shields being provided with depending flanges. 45 4. A moving -picture apparatus provided with a plurality of flame-shields, arranged at opposite sides of the path traversed by the film in its passage across the light-aperture and in proximity to the latter and extending at an 50 angle to the film and out of contact therewith throughout their length, said flame -shields comprising non-inflammable plates adapted to prevent the spread of the flame from the portion of the film in front of said aperture to 55 that above the same. Witness my hand this 29th day of March, 1904, at the city. of New. York, in the county and State of New, York. WILLIAM ELL WOOD Witnesses: Alan Charles McDonnell, William R. Baird.
