Abstract: 469,659. Kinematograph apparatus. BEAUMONT. G. R. Jan. 24, 1936, No. 2263. [Class 97 (i)] [Also in Group XV] Apparatus for enabling a race game to be played comprises four cards arranged at rightangles around an axis and carrying images of competing animals in varying successive order, the rotation of the axis and cards being stated to give a kinematographic effect of motion so that the competitors appear in succession to take the lead. Such an arrangement being. drawn on a wheeled carriage past a fixed background or screen depicting a race course, for example, with a winning post is stated to give observers the equivalent of a race. The cards may be formed of a pair of double size cards h<1>, h<3>, h<2>, h<4>, Fig. 2, slotted to fit together on a turntable F of a gramophone, a centre projection b<1> being provided to take a disc, on top of the cards, with sound record appropriate to the race. Such a device may be arranged between the condenser and projection lenses of a projection lantern enabling the moving competitors to be shown on a screen with sound record accompaniment and the lantern may be mounted on a pivoted or moving carriage to allow the apparent runners to traverse a background on a screen and a second lantern may project letterpesss suitable to the race. The axis supporting the cards may be horizontal instead of vertical and may be driven by hand or a motor M, Fig. 4, the upper half of the cards only being exposed to view. An air or water propeller may be carried on a continuation of the axis or an air current may impinge on the exposed top cards to drive the device. This form of the device may also be mounted wholly in a cabinet c<1>, Fig. 6, illuminated by daylight through a window g<1> above or by lamps L and viewed in mirrors m, m<1> below through openings o in the sides of the cabinet. When the axis is horizontal, the images may be borne upon a pair of opposite cards as shown in Fig. 8, which also shows the device mounted on a wheeled carriage adapted to be drawn along by pulling a cord off a shaped pulley G which also rotates the cards. For race game purposes a number of competitors are provided with winding-on drums A<2>, by turning the handles of which the carriages are pulled along towards them, the race being won by the competitor whose carriage brings its kinematographically moving animal first in line with a winning post on the background as seen by observers viewing athwart the course. The course may be on a flat surface or rails, or the devices may be mounted on boats, rafts or other buoyant means for pulling along a water course. In another arrangement a pair of devices with the axis vertical may be connected by a cord c<2>, Fig. 7, wound on drums K, J, the former being driven by a motor. With this apparatus a hunt hay be seen by the observers, that one of the hunters over the drum K, for example, that appears nearest the hunted, when the cord is fully wound and stops, being adjudged the winner. The images may be on opaque cards or out out as silhouettes or may be on transparent cards, and may be suitably coloured to distinguish them.
