76 MOTOGRAPHY Vol. VI, No. 2. No. 988,392. Mutoscope. Barrett Smith, Boston, Mass. The invention relates to mutoscopes, or "book of leaves" motion picture devices, and more especially to devices of that character which may be used for purposes of advertising. The object of the invention is to provide a mutoscope of simplest design and easily operated to show its motion picture, and such in design that advertising matter may be carried by the casing if not embodied in the motion picture itself. In the particular embodiment of the invention shown in the drawing, which is copied to accompany 988,392. this review, the inventor shows the same in the form of a paper weight, suitable for use upon a desk in the ordinary manner of use of a paper weight, although the invention is not so limited at all times. In the figure, F is a casing having the shape of a triangular prism, of such size and construction as to adapt the same for use as a paper weight. A mutoscope pad A, consisting of a number of picture cards showing successive views of an object, scene, etc., is secured in a suitable holder B. The rod D is pivoted in the casing and the holder B secured thereto. When the rod D is rotated, as by bringing the handle I upward to the position shown, the picture pad will pass over and above the check G and will be held in the position shown in full lines. As the rod D is rotated by moving the handle / downwardly, the pictures printed on the upper sides of the picture cards will be successively moved past the edge of the check, which preferably extends from one side wall of the casing to the other, and be exhibited to the observer looking through the opening in the front wall of the casing in the general direction of the arrow X until the pad has the position shown in dotted lines at A' in line with the horizontal shelf H. The walls of the casing may be provided with advertising matter or with one or more brackets such as shown at L for holding a calendar or advertising matter. The picture pads will preferably be illustrative of the business of the advertiser. The claims are eight in number, of which the following three are selected as typical : 1. An article of manufacture comprising a casing provided with an opening in one of its faces, a rod pivoted therein, a pad consisting of a series of picture cards secured to said rod, a check pivoted to said casing and arranged to permit said pad to pass upwardly and over the same, a lip on said check normally bearing against the casing whereby said check will hold said pad in position above said opening, and means whereby said rod may be rotated for successively bringing said pictures below said opening. 6. An article of manufacture comprising a casing provided with an opening in one of its faces, a rod pivoted therein, a pad consisting of a series of picture cards, a holder for said pad, a rod pivoted to said casing, means eccentrically securing said rod to said holder, a check pivoted to said casing and arranged to permit the pad to pass upwardly over the same, a lip on said check normally bearing against the casing whereby said check will hold said pad in position above said opening, and means whereby said rod may be rotated for successively bringing said pictures below said opening. 8. As an article of manufacture, a paperweight provided with an opening in one of its walls, a pad consisting of a series of picture cards pivoted to the walls of said paperweight, means for successively exhibiting said pictures at said opening, and means whereby the movement of the lower-most picture cards is rendered slower than that of the uppermost cards. No. 988,473. Film Feeding Mechanism. Maximilian Klaiber, New York, N. Y., assignor to American Bioscope Company, Brooklyn, N. Y. The object of the invention is to provide a means for feeding unperforated film, either in the camera or in the projecting machine. The patent discloses a complete motion head, for projecting motion picture films, but the principal improvement, both as disclosed in the description and as covered by the claims, is found in the film driving mechanism. This mechanism is illustrated in the accompanying illustration. The principal feature of the film feeding apparatus itself is the pair of chains. A set of chain-gear sprocket wheels carry the chains, proper gearing being provided that all chains may travel at the same speed. Upon selected links of the chains, every third link being selected as the device is shown in the illustration, are grippers for gripping the motion picture film. These grippers, marked pj and P4 in the illustration, approach each other when the chains are nearest each other, and catch and hold the picture film marked io between them. During that portion of the chain travel when the film is held between the pairs of grippers of the chains, the chain links move straight downward, and with an even tension toward 9SS.473. each other, gripping the film tightly and drawing it positively with the movement of the chains. Suitable driving apparatus of any type may be provided for the chains, driving them either intermittently or continuously; some projecting machines require the latter provision. Of the sixteen claims of the patent, the following four are selected as typical, and as further serving to outline and limit the invention of the patent:
