28,860. Samuel, E. Dec. 30. Scoring and marking.-A billiard marker is formed by adaptation, with certain additions, of the adding-mechanism described in Specification No. 26,520, A.D. 1903, [Abridgment Class Registering &c.]. Two similar sets of wheels b, Fig. 2, numbered to represent hundreds, tens, and units, are actuated by ladder-like chains passing around them and around similar wheels d freely mounted on shafts a5. The whole is enclosed in a casing provided with slots to enable the score to be seen and to enable the chains to be operated. The wheels bare freely mounted on shafts a3, and the units wheel is provided with a catch b5, Figs. 2 and 11, which at every revolution of the wheel is operated against the action of a spring by a camprojection b6, and is caused to engage a ratchet-wheel b2, fixed to the tens wheel b by means of springs which allow a lateral movement to the wheel b2. In a similar manner, motion is transferred from the tens to the hundreds wheel. The units wheel d is provided with ten studs d2, which are engaged by spring pawls e on a shaft e', to prevent the wheel from running back. Each time that 50 is scored, a projection d3 on the tens wheel d, Figs. 2 and 5, depresses a lever f and causes a shaft g to rotate, and this rotation is transferred to arms g4, g5, which respectively operate an arm j of a device for registering the total number of games scored, and the striker bar k2 of a bell k. The arms j, which operate a toothed wheel j2 forming part of a registering-device similar to a cyclometer, are so constructed that only alternate arms operate the wheel j2, to prevent the wheels from being operated when the second player reaches 50. At the end of a game, a rod m' is depressed, which acts on the arm g5 and so rings the bell, and also moves an arm j to bring an operative arm into position for the next game. The rod m2 also depresses a lever, which moves the spring pawl e, and so allows the marker to be re-set. Gear wheels, accessible by means of a locked cover, are used to re-set the registering- device. The movement of the operating-chain c, Fig. 8, is arrested by a slide o5, which is raised by the finger of the operator pressing its end o6, thus causing it to act on a cam portion o8 of a catch o', to bring the catch into position, as shown in Fig. 8, to stop the chain. The casing may be fitted with a clock.
