He invented the first practical "taking" camera and evoked the enthusiastic cooperation of George Eastman in the production of this tape-like film, and the modern motion picture was born. The projecting machine was substantially like the "taking" camera and was so used.
But whereas travelers, hitherto, had carried that up a sleeve or in a breast-pocket, it would have its journal in its cone-shaped head; the little openwork box, five inches square, with the tape-like paper winding from one to another of the wheels within and the tiny pencil making shorthand markings, curve or dash, as the air pressed upon it, until it got beyond the air-belt altogether out into that bitter void of space, where pressure there was none.
For many nights he had had but little sleep, and that made hideous by dreams filled with the unceasing whir and click, click, click of the ticker. At times he had dreamed that a tape-like snake with endless coils was twining itself about him.
Edison's work in this direction comprised the invention not only of a special form of camera for making original photographic exposures from a single point of view with very great rapidity, and of a machine adapted to effect the reproduction of such pictures in somewhat similar manner but also of the conception and invention of a continuous uniform, and evenly spaced tape-like film, so absolutely essential for both the above objects.
This method was obviously too slow and too expensive. Edison with his keen mind approached the difficulty and after a prolonged series of experiments arrived at the decision that a continuous tape-like film would be necessary.
It reads as follows: "An unbroken transparent or translucent tape-like photographic film having thereon uniform, sharply defined, equidistant photographs of successive positions of an object in motion as observed from a single point of view at rapidly recurring intervals of time, such photographs being arranged in a continuous straight-line sequence, unlimited in number save by the length of the film, and sufficient in number to represent the movements of the object throughout an extended period of time."
In this diagram, A represents an outer light-tight box containing a lens, C, and the other necessary mechanism for making the photographic exposures, H<1S> and H<2S> being cases for holding reels of film before and after exposure, F the long, tape-like film, G a sprocket whose teeth engage in perforations on the edges of the film, such sprocket being adapted to be revolved with an intermittent or step-by-step movement by hand or by motor, and B a revolving shutter having an opening and connected by gears with G, and arranged to expose the film during the periods of rest.
Angry with himself he tried to hide his face from their eyes by gazing down sideways into the shallow swirling water under the bridge but he still saw a reflection therein of their top-heavy silk hats and humble tape-like collars and loosely-hanging clerical clothes. Brother Hickey. Brother Quaid. Brother MacArdle. Brother Keogh.
The tape-like surface of the road diminished in his rear as far as he could see, and as he gazed a moving spot intruded on the white vacuity of its perspective. It was a human figure running. Clare waited, with a dim sense that somebody was trying to overtake him.
It probably arises from the horn being in the line of vision, for the variety named kuabaoba, which has a straight horn directed downward away from that line, possesses acute eyesight, and is much more wary. All the wild animals are subject to intestinal worms besides. I have observed bunches of a tape-like thread and short worms of enlarged sizes in the rhinoceros.
