Fithian, Philadelphia. In the framework 6 is a hinged box 8, p r e f e ra b 1 y square, and having a drumhead 0. Upon the drumhead are a large number of large shot 14. A net 10 prevent the shot from escaping. A tapered box 11 is mounted above the drum, forming a sound-modifying chamber 12. The box may be shifted to shake the shot by use of the Fig. 1,060,717. The box may be shifted to shake the shot by use of the handle 16, the spring 21 tending to balance the weight of the drum. The drum head also may be beaten by the drumstick 23 and pedal 2j. The inventors state : Our invention relates to stage noise apparatus, that is to say, the apparatus for simulating noises for the purpose of rendering more realistic the scenic effects of dramatic productions and moving picture exhibitions. The principal object of our invention is to provide a simple and efficient apparatus for producing a variety of noises for imitating the sound of waves, escaping steam, locomotives, musketry, storms and other noises. No. 1,061,101. For an Improved Safety Attachment for Motion Picture Projecting Machines. Issued to Charles E. Morton, Edwardsville, 111. (Application filed March 26, 1910.) This invention provides means for automatically cutting off that portion of the film which is between the two spools during projection, so that if the film in the film gate becomes ignited all burning of the film at points beyond the feed mechanism will be prevented and the film in the magazines will be protected. The illustration shows a side view of a projecting head, having feed reel 1 and take-up reel 2 and inter Fig. 1,061,101. mittent mechanism at j not shown in detail. The film A passes through a slot 6 in a support 4. A shearing member is fixed at rj and a 14 is held by a cord ij passing over guide pulley 19 and connected to a fusible wire 21, the fusible wire being anchored at 20. A spring is arranged to draw the knife forward to cut the film A when the knife is released by the melting of the fusible wire, the fusible wire of course melting quickly from the heat of the flaming celluloid in case the film in the gate should catch fire. There is arranged also a knife jo between the film gate and the take up reel, a spring being arranged to draw the knife to cut the film and a cord being arranged to the fusible wire 21 to hold the knife from cutting except in the case of fire to melt the fuse. No. 1,062,081. For an Improved Heat Arresting Screen. Issued to Charles H. Converse and W. H. C. Rider, Chicago, 111. The improved heat screen is shown at E in the illustration. Coloring devices for tinting the picture are shown at H. Two of the descriptive paragraphs of the patent and one of the five claims, are quoted : One of the objects of our present invention is to provide an improved heat arresting or protecting screen between the light and the film of the picture apparatus, for the purpose of deflecting or absorbing the heat rays, or a sufficient amount of the heat from the light, as to prevent the temperature of the film from rising to a dangerous degree. We have discovered that by interposing a sheet or screen of celluloid between the arc light of the apparatus and the film, Fig. 1,062,081. certain heat rays which would otherwise affect the celluloid film, are absorbed or arrested by the celluloid screen, so that the film is protected and remains at a safe degree of temperature. According to one feature of our improvement, we interpose a sheet E, of transparent celluloid, cellulose, fibroid, or similar material, between the lamp and the film, thus absorbing the heat rays which affect such celluloid material, and rendering the use of the celluloid or similar film perfectly safe. This sheet of celluloid is preferably located near the point where the light emerges from the lens or shaping tube of the lamp house, at which point the circle of light is about three inches in diameter, covering an area of over six square inches, or many times greater than that at which the moving picture film is exposed. As the heat rays are thus spread over such a large area of the celluloid screen, the temperature of the screen at no time rises to a dangerous degree, even when exposed to the light continuously, consequently there is no danger of the screentaking fire, and the film which may be of the usual gelatin coated celluloid, or similar composition, is safely protected from the heat. In a picture projecting apparatus, the combination with a lamp, and a film of inflammable material, of a heat resisting screen composed of like material and interposed between the lamp and the film. No. 1,062, 324! For an Improved Device for Reproducing "Talking Pictures." Issued to Henry T. Crapo, New York, N. Y., assignor to George R. Webb, Baltimore, Md.
