February. 1912. MOTOGRAPHY 79 Recent Patents in Motogfraphy By David S. Hulfish UNITED STATES Patent No. 1.001.:?S->. Moving Picture Toy. Ernest W. Davis, Chicago, 111. The invention comprises a card having pictures of an object in two positions, on the opposite sides of the card, together with a special means Eor alternately 1,004,382. presenting to view, at moments of rest, the opposite sides oi the card. A suitable card, labeled A, has the two pictures, here shown as a girl pulling a string of chewing gum. One side of the card bears the picture with the hand extended, while the other side of the card bears the picture with the hand less extended, as indicated in the dotted lines of the hand near the center of the card. The pictured card A is secured to a wire B having a handle D to be twisted between the ringers to rotate the card. The wire B passes through the holes G and G in the card F. and a band E in the wire B strikes the card F as the pictured card turns. The card F being held in one hand and the handle D being twirled with the fingers of the other hand, the angle E in striking the card F causes the pictured card to check momentarily in its revolution twice in each turning, thus showing the sides of the card alternately at moments of rest. The claims are based upon the feature of the card F and the angle E for the purposes of checking the card A as described. Xo. 1,005,935. Eight Shield for Moving Picture Projecting .Machines. James A. Cameron. New York, X. Y. According to the pre-ent invention, the film E protected effectually from the heat of the are lamp by inter •ig a large shield between the projector and the lamp house, and by providing a free air space between the fire shield and the projecting machine itself. The shield con of a large flat plate of metal, or of any non-inflammable material, -uch a a-besto-. which is supported between the lamp house and the projector, and is provided with a hole just large enough to permit to pass the cone of light which falls upon the picture film in the film window. All superflous light rays are intercepted before they reach the projecting machine, and the beam of light which passes through the opening in the shield max be made to correspond to the film window. The beam of light thus may be reduced to the proper size for the film window, passing through the film window to the film without striking the film gate about the film window and thus without heating the film gate and adjacent parts of the projector. The heat absorbed by the fire shield is prevented from reaching the projector by the free air space between the shield and the body of the projecting machine. The fire shield is so arranged that the motion head cannot be operated until the fire shield is in position. A shutter for the opening of the shield shuts the light 1,005,935. from the film when the picture E not being projected. The illustration accompanying shows the face view of the shield. The patent has fourteen claims. Xo. 1,005,936. Moving Picture Projecting Machine. James A. Cameron. New York, X. Y. In projecting machines there are provided usually an upper steady \\-v<\ sprocket for giving a continuous feeding movement to the film, a it is drawn from the feed magazine, and an intermittent sprocket for shifting the film in front of the film window. These t kets are so related a to maintain a degree of -lark in the film between tin steady sprocket and the film gate, One ob
