Projectoscope

Vitascope was an early film projector first demonstrated in 1895 by Charles Francis Jenkins and Thomas Armat. They had made modifications to Jenkins patented Phantoscope, which cast images via film and electric light onto a wall or screen. The Vitascope is a large electrically-powered projector that uses light to cast images. The images being cast are originally taken by a kinetoscope mechanism onto gelatin film. Using an intermittent mechanism, the film negatives produced up to fifty frames per second. The shutter opens and closes to reveal new images. This device can produce up to 3,000 negatives per minute. With the original Phantoscope and before he partnered with Armat, Jenkins displayed the earliest documented projection of a filmed motion picture in June 1894 in Richmond, Indiana.
