Concerning projection, this manufacturer said: “Pictures cannot succeed without perfect projection, resulting in absolutely clear, flickerless pictures. The longer the period of rest of each picture on the screen, the better the detail and the clearer the picture. This I accomplished by means of an intermittent movement.

“You know that in projecting pictures the motion in the film is not continuous in front of the aperture of the machine head, each picture pausing long enough for proper projection on the screen. Through this intermittent movement I obtain a longer period of rest for each picture, which accomplishes perfect projection of pictures without flicker.

“A very annoying feature until recently has been the losing of the lower film loop, due to poor patching of the film, tearing of the perforations in the films, etc., causing the film to jump the lower sprocket, with the probable tearing and re-adjustment of the film. This I overcame with my loop-setter invention. To explain briefly—

“As the full movement at the upper and lower reel is continuous, while at the aperture it is intermittent, a loop is necessary as a feeder for the take-up or the lower sprocket. If this loop is lost, the film becomes taut, the machine stops and the film may break. The loop-setter instantly readjusts this loop automatically, keeping it always in force.”

The taking of pictures is, of course, one of the interesting phases of the business from a popular standpoint. Here we find not only large sums invested but the action, setting, plots—in fact, the entire order of pulsating life and convincing reality that give to motion pictures their remarkable hold upon the public. In vying with each other to make the most attractive films possible, the concerns in this end of the industry engage the most talented players, who are transported on long journeys so that the settings may be realistically satisfactory; while often the company includes not only two-footed actors, but horses, one or two clever dogs and sometimes a trained bear and other animals, besides all of which there is usually an array of “properties” that far exceeds in quantity and variety the list of such appurtenances carried by the average stock theatrical company or theater of the ordinary kind.

Then, too, there is the presentation of the pictures, where we find another vast outlay of money in land, buildings and equipment. And, remember, the matter of taking and presenting the pictures must not be considered only from the amusement standpoint. Motion pictures are being employed more and more every day for educational and industrial purposes.


The Story of Leather[70]

We all know that leather is the skins of animals, dressed and prepared for our use by tanning, or some other process, which preserves them from rotting and renders them pliable and tough.
