Abstract: 358,071. Billiards markers. ROSENSTENGEL, B. L., 143, Queen Street, Brisbane, Australia. May 26, 1930, No. 16138. [Class 132 (ii).] In a marker for billiards, snooker, pool, and other games of the type in which pointers M, Fig. 1, are slidable in front of rollers B each rotatable to display individual rows of markings thereon, manually adjustable cam mechanism adapted to be set in predetermined positions is provided for varying the amplitude of the rotary movement allowed to the rollers in order to impose a variable limit upon the number of points scorable in games of different denomination. The rollers are manually rotated against the action of return springs by knobs frictionally connected to the rollers. The forward rotation of the rollers is limited bv the co-operation of pawls C<2>, Fig. 5, with stepped discs C carried by the rollers. Backward rotation of the rollers is normally prevented by pawls C3 engaging teeth on the discs. The pawls C<2> are set to control the extent of play by studs D carried by a slide E, that is positioned by a cam E<2> rotatable by an operator's key E<4>, Fig. 1, inserted through a hole E<8>. The setting of the control cam is displayed by a drum indicator E<6>. At the end of a game, the operator's key is inserted in a slot H<7> and a cam shaft H, Fig. 4, is set to release one of a series of bars G<1> corresponding to the kind of game concluded. The released bar is moved downwardly by depressing its key G<4> thus actuating the corresponding counter J<2>, ringing a bell P, and through projections G, Fig. 4, and F<1>, Fig. 5, on the slide E disabling the pawls C<3> to reset the rollers. The kind of game last played is indicated by a flap K, that is rotated into displaying position by the depressed bar G<1> and is then held by a stop L<2> controlled by the slide E. A device for printing a player's marking sheet may be provided, such device comprising a rotatably adjustable stamp Q<1>, Fig. 14, against which the sheet is pressed by a platen Q<2> actuated upon the depression of a release bar G<1>. An ink-ribbon Q<4> carried by rolls Q<6> passes between the stamp and sheet. In a modified form of printing device, the platen is fixed and the stamp is carried by the release bar. In a marker for use by three or four players, two slides E are controlled by the manually set cam to allow either the top roller or both rollers to be released for rotation. In a modified form of the apparatus, Fig. 21, the release bars become operative upon the insertion of tokens to zeroize the rollers and to position the control cam E<2>. A token T inserted into a slot U<1> corresponding to the kind of game to be played, serves to connect the upper parts of one of the release bars to its actuating lower part S<1> by compression of the coin between a fork S<5> and a pin S<3> on the upper and lower parts of the bar respectively. As the bar is moved downwardly, projections W<2>, W<3> thereon engage arms W, W<1> to position the control cam E<2>, Upon the return movement of the bar, a lever V is tripped by a stop V<1> to eject the coin into one of a number of trays X.
