PROVISIONAL SPECIFICATION.
An Improved Timing Apparatus for Games of Billiards.
We, ARNO MARTIN, Merchant, of 6, Augustusstrasse, Dresden, and WILHELM
GÜNZEL, Mechanical Engineer, of Trachau, near Dresden, in the Empire of Germany
do hereby declare the nature of this invention to be as follows:-
:-
The herein described billiard clock belongs to. that class in which the insertion
of the billiard balls in a case, connected or supplied with clockwork, stops the
clockwork while the withdrawal of the balls from the case sets the clockwork
again in motion the latter running until again stopped by the insertion of
the balls in the case.
According to the requirements of the game, the billiard clock is arranged to
receive either one or two sets of balls, in the latter case one set lying above
the other. In the following description it is assumed that two sets of balls
are to be used, although we do not confine ourselves to this number only. The
clockwork is arrested in its movement only when both sets of balls are in the
case, while it is set in motion again when only one set is removed; it making no
difference whether the upper or the under set is removed.
In carrying out this invention the clock case is provided with two sets of open-
ings of the exact size of a billiard-ball for the reception of the balls, and with
two tracks or ways one above the other on or in which the balls rest in the case.
Both tracks are hinged to the case and incline downwards towards the door,
so that the balls, when this door is opened can be taken hold of and removed
or will roll out by their own weight through the resulting opening. The upper
The
track is bent up on its front end in order that the balls may not fall out.
under or lower track is shorter than the upper, for the purpose of letting the
weight of only two balls set thereupon; because the halls which rest upon it,
and which are used for the game of pool are larger than those upon the other
track, which are used in cannon games.
The two tracks are united with each other by rods or similar connections.
A regulating screw with spring is provided underneath the lower track for
the purpose of raising and holding up the tracks should only one set of balls
be in the case. The weight of both sets of balls overcomes the resistance of the
spring and compresses it, and the tracks come into such a position that a rod,
hook, or latch, as the case may be and as is most convenient causes the stoppage
of the clock-work in the lower part of the case.
The withdrawal of the balls from the case can only be effected through the
door, which is furnished with a handle and lock.
As before mentioned, instead of two sets of balls, only one may be put into the
case; in which instance the upper track, as well as the connecting pieces between
the two tracks, as well as one of the insertion openings, can be dispensed with.

We, ARNO MARTIN, Merchant, of 6, Augustusstrasse, Dresden, and WILHELM
GÜNZEL, Mechanical Engineer, of Trachau, near Dresden, in the Empire of Germany
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:-
-
The herein described billiard-clock belongs to that class in which the in-
sertion of the billiard balls in a case, connected or supplied with clock-work,
stops the clock-work, while the withdrawal of the balls from the case sets the
clock-work again in motion, the latter running until again stopped by the
insertion of the balls in the case.
According to the requirements of the game, the billiard-clock is arranged to
receive either one or two sets of balls, in the latter case one set lying above the
other. In the following description it is assumed that two sets of balls are to be
used, although we do not confine ourselves to this number only.
The clock-work is arrested in its movement only when both sets of balls are
in the case, while it is set in motion again when only one set is removed; it
making no difference whether the upper or the under set is removed.
In carrying out this invention the clock case is provided with two sets of
openings of the exact size of a billiard ball, for the reception of the balls, and
with two tracks or ways, one above the other, on or in which the balls rest in
the case.
In the accompanying drawings Figs. 1 and 2 are sectional elevations at right
angles of a billiard-clock constructed according to this invention, and Fig. 3
a part front elevation of the same. In all the figures similar letters refer to
similar parts.
The two tracks a, b on which the balls rest, are connected to the case by
hinges d, and incline downwards towards the door e, so that the balls when
the door e is opened, can be taken hold of and removed, or will roll out by
their own weight through the resulting opening.
The upper track a is bent up on its front end, in order that the balls may
not fall out. The under or lower track b is shorter than the upper track, for
the purpose of letting the weight of only two balls rest thereupon; because the
balls which rest upon it, and which are used for the game of pool, are larger
than those upon the other track, which are used in common games.
The two tracks are united with each other by rods or similar connections f.
A regulating screw g, with spring his provided underneath the lower track
for the purpose of raising and holding up the tracks, should only one set of balls
be in the case. The weight of both sets of balls overcomes the resistance of the
spring and compresses it, and the tracks come into such a position that a rod i
hook or latch as the case may be, and as is most convenient, causes the stoppage
of the clock-work in the lower part of the case.
The openings for the insertion of the balls are on the sides of the case,
and their size is so determined that a ball will exactly pass through them,
and as the balls by reason of the downward inclination of the tracks roll
in the direction of the door, no one can remove the balls, or grasp them through
the openings.
The withdrawal of the balls from the case can only be effected through the
door, which is furnished with a handle m and lock n.
As before mentioned, instead of two sets of balls, only one may be put into

page_text: the case, in which instance the upper track, as well as the connecting pieces
between the two tracks, as well as one of the insertion openings can be dispensed
with.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
--
1. A billiard-clock, characterised by a casing provided at the side with inser-
tion openings ke of the size of the billiard balls, inclined tracks or ways a b
hinged in the casing and connected with each other, a spring support for the
tracks or ways adapted to be depressed by the weight of the balls, and a de-
pending piece fixed to the lower track and engaging the clock-work when the
track is depressed substantially as described.
2. The improved billiard-clock substantially as described with reference to
the drawings.
