Abstract

11,183. Chipperfield, W., and Garforth, W. E. Nov. S, 1912. Cameras, reflex.-View-finding means for a kinematograph camera comprise a mirror N mounted on a sliding arm N<4> so that it may be interposed or withdrawn from a position for intercepting the image between the lens and the film Q to reflect it on to a ground-glass screen N', where it can be viewed through an aperture N<2> in the camera. The sliding arm N<4> is connected to one arm of a bell-crank lever P, the other arm of which operates a shutter N<3> for closing the aperture N<2> when the mirror is withdrawn from position.
