A smaller dial on
one division by the revolution of two handles outside the dial.
the face of the other indicates the number of games of 50 (or more) played and
by a suitable mechanical device each game of 50 (or more) is recorded when either
hand first reaches the 50 mark, but the movement of the other hand to the starting
place does not affect the record which remains until another 50 (or more) points
have been scored. Further by another device an error to the extent of not more
than 5 points can be corrected by moving either hand backwards. Thus alterations
are prevented and the whole works being under lock and key a check is kept on
the number of games played. A bell sounds after each game and other dials mark
the whole number of points scored in a long match.

COMPLETE SPECIFICATION..
An Improved Billiard Counter or Marker.
I, WILLIAM TAYLOR, of 12 Union Street, Coupar Angus, in the County of
Perth, N.B. Watchmaker and Jeweller, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
A. dial, having two hands coloured differently and pivoted at its centre, is divided
into fifty or more parts, each part being duly numbered. The hands are respectively
A
moved through one division by the revolution of two handles outside the dial.
smaller dial on the face of the other indicates the number of games of fifty or more
played, and by a suitable mechanical device each game of fifty or more is recorded
when either hand reaches the fifty mark, but the movement of the other hand to
the starting place does not affect the record which remains until another fifty or
more points have been scored.
Further, by another device an error to the extent of not more than five points
can be corrected by moving either hand backwards, thus alterations are prevented,
the whole works being under lock and key. A check is kept of the number of
games played. A bell sounds after each game, and the other dials mark the whole
number of maints scored in a long match.

The dial 10. is divided into say fifty parts, each part being duly numbered.
The two hands 11. and 12. are coloured differently and pivoted at the centre.
These hands are respectively moved one division by the revolution of handles 13.
and 14. Smaller dials 15. 16. and 17. on the face of the other indicate the number
of games of fifty or more played; as shewn these dials would register a thousand
games of fifty each. The handle 13. when rotated actuates the hand 11. by means
of the left hand worm 20. and worm wheel 21, and similarly the handle 14. actuates
the hand 12. by means of the right hand worm 18. and worm wheel 19. The
direction of motion of each hand is prevented from being reversed to the extent of
more than five points by means of the device more fully shown in Figures 8. and 9.
The arrow in Figure 9. shows the normal direction of rotation of the spindles 22.
24. is a nut on the spindle so adjusted that on the handle making five
revolutions reverse to its normal direction it is traversed along the screw on such
spindle until it is jammed against and upon the pin 25. So long as the spindle
rotates normally the nut freely passes the pawl 26. whose recoil is rendered
noiseless by means of the rubber pad 27. Figures 5. 6. and 7. more fully illustrate
the method of communicating the motion of each hand 11. and 12. to the pointer 28.
The hand 11. and the wheel 21. are both fixed upon the spindle 29. their motion
being communicated to the pinion 30. by means of the pawl 31. Similarly the
wheel 19. and the hand 12. move together, but independent of the spindle 29, a
pawl 32. communicating their motion to the pinion 30. From this it will be seen
that only the motion of one hand can be communicated to the pointer 28. at one
time, the rotation of the other hand causing the projections 33. or 34. to advance.
from their particular pawl, in which case the pointer 28. will not move until the
pawl again comes in contact. The bell 35. is made to sound when the pin 36, that
is to say the hand 11. makes one complete revolution, by releasing the hammer 37.
38. is the clip gear for preventing the handles being tampered with.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
(1) In a billiard counter or marker, the improved combination of parts herein-
before described and shewn in the accompanying drawings.
(2) The herein before described combination of parts for communicating the
motion of the hands 11. and 12. to the dials 15. 16. and 17. as described.
(3) The combination of parts for limiting the backward travel of the hands, as
described.
