Abstract: 9035. Gilmore, D. April 22. Targets.-Relates to disappearing targets and includes means for transmitting to the marksman the result of his shot. Figs. 1, 2, 3, and 9 show the transmitter, and Fig. 7 the target. The transmitter consists (1) of a horizontal frame B, pivoted to the sides of the box, and having a bellows connected to it, and (2) of a pin I which is vibrated horizontally, as the bellows is inflated, by the wires shown in Figs. 1 and 2. The front of the frame Band the bellows with it are raised by the pedal 9, Fig. 9, which engages with a lever 13 protruding through the front of the box. As the front of the frame B rises, the curved piece H comes in contact with the vibrating wires K<1>, and thus the pin I raises one of the pieces Y, Fig. 3, attached to the rods X, which are pivoted on the underside of the cover of the box. By this means, the corresponding wire Z, Figs. 3 and 7, is made to raise one of the figures O, O<1>. The figure O<1> slides in guides m, m<1>, like the figure 0, but, instead of being fixed to the plate n<1>, it is pivoted on the pin w, and a loop is passed round the pin v to prevent it from turning when struck. As one of the pieces Y, Fig. 3, is raised, the latching-bar C moves to the right, but when a certain point is reached, the small curved piece falls under the piece Y and thus the corresponding wire Z is kept strained, but, when the wire Z<1>, Fig. 1, is pulled by the hitting of the target, as explained below, the upper part of the strip e, Fig. 1, is moved to the right, bearing against the end of the latching-bar C, and unlatching the rod X, which has been held up. If the pin I, Fig. 1, and its attached wires J, K, J<1>, K<1> are made to vibrate too much, one of the hanging rods N is struck, so that the pin 0 comes in contact with and raises it and the lever M, Figs. 1 and 9, whereby one of the wires Z<2>, Z<3>, Figs. 1 and 7, is pulled. The wire Z<2> pulls down the pivoted arm y, Fig. 7, connected with a dashpot D', and the wire Z<3> operates the long pivoted arm 5, and thus one of the figures O<2>, O<3> is brought into view. The metal rail 2 prevents sagging of the wire U'. For recording the result of the shot, when the mark 0, Fig. 7, is struck, the pin t<1> is pulled forward, the bar S is rotated and the wire Z' is pulled. This wire causes a hammer h, Figs. 1 and 9, to strike a bell. When the figures O<2>, O<3> are hit, they strike the wires 7, 7<1>, and the pins 8, 8<1> operate the bell shown in Fig. 7. The apparatus shown in Fig. 9, for raising the frame B, Fig. 1, consists of two levers 9, 9<1>. The latter is bent at right-angles, one arm being parallel to the lever 9, and the shorter arm at right-angles to it. The short arm carries a catch, which engages with the arm 13, Fig. 1. On pressing down the pedal, the lever 9 rises in the slot 10, and the frame B, Fig. 1, reaches its highest point before the lever 9 reaches the wider part of the slot. When this part is reached, the catch on the short bent arm is released from the arm 13, Fig. 1, and thus the frame B is free to fall, even though the marksman keeps his foot on the pedal.
