282 MOTOGRAPHY Vol. VI, No. 6. shaft connected to the carriage and extending out through the said slot, and means for locking the shaft in the slot. 4. In a lamp, a casing having a horizontal slot therein, a carriage located in the casing and having oscillatory movement, a light-emitting device supported by said carriage, a shaft connected to the carriage and extending out through the said slot, a guard plate carried by the shaft, and a setscrew to engage the guard-plate and lock the shaft in the slot. No. 1,001,098. Film Winding Mechanism for Moving Picture Machines. Charles R. Uebelmesser, New York, N. Y., assignor to American Moving Picture Machine Company, New York, N. Y. The object is an improved winding mechanism for 1,001,098. the take-up reel by which the film will be wound evenly without being subjected to too great a strain, as sometimes occurs when the friction driving devices of the takeup are set too tight, or for any reason fail to operate properly. The take-up reel is driven by a friction roller upon the film itself. The drawing shows the film slack between the lower steady feed sprocket and the take-up reel. The two claims are themselves brief descriptions of the invention, and may be read in connection with the accompanying figure : 1. In combination with a moving picture machine having a film-driving mechanism, a winding mechanism comprising a rotatable hub upon which a film may be wound into a coil, a stationary spindle upon which .said hub is loosely mounted; an arm pivoted near one of its ends, a driving roller at the other end thereof, and mechanism arranged to transmit the movement of the film-driving mechanism to the driving roller, said driving roller being arranged to engage the outer layer of film upon the hub. 2. In combination with a moving picture machine having a film-driving mechanism, a winding mechanism comprising a rotatable hub upon which a film may be wound into coil, a stationary spindle upon which said hub is loosely mounted; an arm pivoted near one of its ends, a sprocketwheel at the pivoted end thereof, said sprocket-wheel being connected with the film-driving mechanism, a driving roller at the other end of said arm, said roller being arranged to engage the outer layer of film upon said hub, a sprocketwheel connected with the driving roller, and a sprocketchain connecting the two sprocket-wheels. No. 1,001,534. Dissolving View Apparatus. Hugo Krieger, New York, N. Y. The object is to provide an apparatus for exhibiting dissolving views and using but one lamp. The illustration herewith is a top view, or table-top plan, of a double projector having but one arc lamp. In this illustration, a motion head is not shown, but may be fitted in such position that the lamp house may slide to it. Two projecting lenses for the two dissolving slides are shown. One of these receives the light directly, while the other receives it through a reflecting prism, the light having a condenser in either case. In the figure, C is the arc lamp in its house, / is a reflecting prism. Two sets of condensers, D and D are provided, for the two lenses H and H. A dissolving shutter K operates in the same manner as with a dissolving apparatus having two lamps. The little milled head 7-5 enables the operator to turn the prism J slightly to bring his light into center in both his lenses at the same time. The claims are nine in number, and cover very broadly the use of the condenser and prism arrangement, and also the adjustable feature for moving the prism to center the light in the second lens. The first three are as follows : 1. A dissolving view apparatus, provided with a lamp casing, condensers mounted on the said lamo casing, and having their axes arranged parallel one to the other, a source of light in the lamp casing opposite one of the said condensers, and a prism interposed between the other condenser and the said source of light. 2. A dissolving view apparatus provided with a lamp casing, a source of light therein, a pair of condensers mounted on the said main casing and having their axes arranged parallel one to the other, one of the condensers being in front of the said source of light, and a prism adjacent the said source of light and opposite the other condenser. 3.
