Title: Improvements in coin-freed apparatus for playing a game simulating football
IPC: G07F17/38
Filed: 1927-05-25
Abstract: 275,937. Staar, G. T'. L. Aug. 14, 1926, [Convention date]. Table games.-Coin-freed apparatus for playing a game simulating football of the type in which the players manipulate model footballers having articulated legs, comprises a playing surface with a goal at each end, a model footballer before each goal adapted for lateral movement between the goal posts, each footballer being carried by a lever which is pivoted at one end to a fixed point the other end being movable from side to side and carrying means for operating the articulated leg of the footballer. The playing area or ground is enclosed in a glass cover and slopes from the centre to the goals 6, Fig. 2, in front of which are arranged the footballers 7. Each footballer is carried on a lever 39 pivoted beneath the centre of the ground and terminating outside the casing in an operating handle 41. By moving the handle laterally the footballer 7 may be moved across the front of his goal to intercept the ball. Guided upon the lever 39 is a spring- pressed slide 44, Fig. 8, carrying a vertical projection 51 situated immediately behind the pivoted leg 47 of the footballer. The slide may be drawn back by a trigger 46. When the operator releases the trigger the projection 51 imparts an impulse to the leg 47 and projects the ball, if in position, towards the opposite goal. A ball entering a goal passes down a conduit to a transverse channel 18, Fig. 4, where it is arrested by a curved stop 19 mounted on the pivot of a weighted lever 21. One end of the lever projects into the coin shoot 25 so that a coin inserted into a slot 3 displaces the lever 21 and allows the ball 15 to run down the channel 18 and enter a vertical conduit 28, Figs. 4 and 5. By turning an external knob 4, a lifting arm 34 actuated by a crank 38 and link 37 raises the hall up the conduit 28 and ejects it through a flap in the playing area whence it rolls towards one of the goals. If, after insertion of a coin, and consequent liberation of a ball, the lifting arm 34 is in its raised position a pivoted shutter 30 bearing on the lifting arm by means of a pin 33 obstructs the entrance 27 to the vertical conduit 28 and prevents the ball from entering until the knob 4 has been turned to restore the lifting arm to its lower position.
