Title: New or improved apparatus for playing games of the snooker or billiards type
IPC: A63D15/00
Filed: 1936-10-24
Abstract: 471,832. Coin - freed table games. HILL, G., and HILL, F. J. Oct. 24, 1936, No. 28923. [Class 132 (ii)] [Also in Group XVIII] Billiards, tables for.-In apparatus for playing games of the snooker or billiards type, a table with spaced pockets leading into inclined guides or runways which conduct pocketed balls to a common central runway, is provided with means actuated by the balls whereby they are selected in accordance with their diameters and with the order in which they reach the central runway and are distributed to different points where certain balls may be trapped while others may return to the player. In the embodiment shown, adapted to the game of snooker, the balls are of different sizes ; for example, the cue-ball A, Fig. 1, is smaller than the red object balls B so that, on reaching the central runway 10, it falls through a slot therein and is returned to the player through the runway 12. The red balls pass along the runway 10 to a wider portion 13 where they fall through into a runway 14, Fig. 4, and are trapped by a shutter 15. The other coloured balls C are again larger in diameter so that, on entering the central runway they pass right along to the section 20; here, according to the arrangement of a device 19, they are either trapped or returned to the player. In the latter case, the ball, in rolling off the end of the runway, moves a trigger 22 which, being linked to a lever 18, lifts another trigger 16 and the stop 19. If a red ball is now pocketed, it moves the trigger 16 &c., back into the position shown. If, however, another coloured ball follows instead of a red ball, it is trapped by the stop 19, a bridge-piece 23 preventing it from jumping over. A convenient coin-freed mechanism comprises a slide 25, Fig. 7, with spaced openings 29 and 30 to receive two coins which are laid flat and are supported on the lower of a pair of cast guide members 31. Two spring- pressed pawls 32 prevent the slide from being pushed right in without the necessary coins, while a wedge-shaped member 33 serves to discharge the coins. A full-stroke ratchet and pawl at the edge of the slide 25 prevent the slide from being withdrawn before it has been pushed fully home. The slide 25, Fig. 1, is connected to a cam and, on being pressed home, raises the shutter 15, Fig. 4, to release the red balls B. The raising of the shutter 15, lifts the trigger 22, so that when the slide 25 is pulled out again the coloured balls C are released. A cam rod 28, Fig. 1, projects into the runway to prevent the red balls from being repeatedly used while the slide 25 is pushed in. In a modification, the cue ball is the largest and runs along an upper runway, while the red and coloured balls fall through to lower runways as described.
