I THOMAS TRUSSELL of number four Arrow Terrace Fisher Gate in the town
of Nottingham in the County of the same town, Mineral Surveyor do hereby
declare the nature of my invention for IMPROVEMENTS IN THE METHOD OF
MARKING & REGISTERING THE GAME OF BILLIARDS AND IN THE APPARATUS
CONNECTED THEREWITH, to be as follows, and is an improvement upon the inven-
tion described in my Provisional Specification number 5531/84 and by which the
score can be more easily and correctly marked :—
Upon a wood or suitable frame or similar contrivance is mounted an axle or
pivot upon which are placed two discs or dials capable of revolving upon the
aforesaid axle.
The front disc aforesaid is smaller in diameter than the back one, so that the
outer portion or edge of the back disc can be seen projecting beyond the circum-
ference of the smaller disc.
Along the circumference or outer portion of the aforesaid smaller discs at equal
distances are written the figures 1. 2. 3. 4. 5. 6. 7. 8. 9 & 0 and opposite each of
these figures and on the same disc is a small peg or projection making 10 in all,
along that portion of the larger disc that can be seen projecting beyond the
smaller disc, are written at equal distances, the figures 1. 2. 3. 4. then a space left
equal to the distance between two figures then the figures 1. 2. 3. 4 at the same
distance from each as the first figures.
Over the top of these discs is placed a cover perforated so that one figure
only on the same disc can be seen at the same time, the others being covered
over by it.
On this cover aforesaid and opposite each peg on the smaller disc aforesaid
is written the figures 1. 2. 3. 4. 5. 6. 7. 8. 9.0 one figure only being opposite
each peg.
A second set of discs exactly similar in all respects to the afore described discs
are used for the second or other plaver.

page_text: F is the Cover.
C is the small disc and D the larger disc as seen through the perforation in the
cover F.
0 & 1 are also figures seen on discs C & D through the same perforation
in cover F. the remaining figures are shewn dotted where covered by F. E are the
pegs on disc C. L is a counter shewing number of games played.
To mark game (it being shewn on plan as plain 10. spot 20) I proceed thus, suppose
plain scores 10. take hold of peg opposite 0. on cover, move it to left from right
to 0 again on cover, the 1 on dial D will pass on & the figure 2 will take its place
shewing 20 as score of plain, suppose plain again strikes 7, I take hold of peg
opposite 7 on cover and move it round to left from right to 0 on cover the score
will then shew 27 to plain, the smaller dial shews the units and the larger one tens,
and the unit dial always advances the tens dial 1 figure when it gets its 0.
opposite 0 on cover by means of wheels at back of dials or discs.
The apparatus above described is intended for marking 50 point games if 100
point games are required to be marked the dial D is figured 1 to 9 instead of 1 to 4
If higher games are required three or more dials are used for each player.

I, THOMAS TRUSSELL of Number four Arrow Terrace, Fisher Gate in the town
of Nottingham, in the County of the same Town, Mineral Surveyor, do hereby
declare the nature of my invention for IMPROVEMENTS IN THE METHOD OF
MARKING & REGISTERING THE GAME OF BILLIARDS, AND IN THE APPARATUS
CONNECTED THEREWITH and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Upon a frame or support A, is the Axle or pivot B and upon which is placed the
two discs or dials C & D, capable of revolving upon the axle B aforesaid.
The outer portion of these discs C & D are figured as shewn on figure 4 of the
accompanying drawings.
Opposite each of the figures 1. 2. 3. 4. 5. 6. 7. 8. 9. 0. on dial or disc C is a pin
or projection E there being 10 in all.
Over the top of the dials C & D is placed the cover F F. (fig. 2) a portion of
which is cut away, so that one figure only on each of the dials C & D can be seen at
the same time, the other figures on the dials being covered over by the said
cover F. F. it is also arranged that the small pins E. E. can revolve together with
the dial C. independent of the cover F. F which remains stationery and carries the
figures which are opposite each one of the pins E. E (or their equivalents) as shewn
on fig. 2 of the accompanying drawings.
Attached to the back of the dial C, is the toothed segment wheel I. (with say
10 teeth on the segment of the circle forming the wheel) and in such a manner
that at each revolution of the dial C, and when the figure 9 on dial C passes the
opening in Cover F. F. it comes into gear with the toothed wheel G. (which has
10 times the number of teeth on it that the wheel I has) and causes it to revolve
oné tenth of its circumference.
In gear with the wheel G. (which has the same number of teeth on it as the
wheel G.) is the wheel H which is attached or forms part of the dial D and when
the wheel G. is moved one tenth of its circumference, it causes the wheel H to
revolve th of its circumference and with it the dial D. now as the figures on
dial D are placed at a distance of one-tenth the circumference of the dial D from
each other it follows that at each revolution of the dial C. the dial D is advanced
one figure towards or past the opening in cover F. F.
Another set of dials exactly like the herein before described dials are used for
the second or other player, as shewn on accompanying drawing fig. 2.
To mark the game of Billiards with the herein before described apparatus, and
assuming that the present score is plain 10 spot 20. as shewn at figure 2 of the
accompanying drawings I proceed thus :-
Suppose plain scores 5 points, I take hold of peg E which is opposite the
figure 5 on the cover F. F. and move it to left from right as far as 0 on the

page_text: cover F. F. when the large 0 on dial C will move forward, and the figure 5 will
appear and take the place of the 0 at the opening in Cover F. F. and shew the
state of the game to be plain 15 and spot 20.
Suppose plain scores 4 points more I take hold of peg E which is opposite
figure 4 on Cover F. F. and move it to 0 on cover as before, when the figure 5 will
move forward and the figure take its place and shew the state of the game to
be 19, that is the figures seen through the opening in the cover F. F. are 1 on the
Dial D and 9 on the dial C.
When the figure 9 on dial C passes the opening in the cover F. F. which is at
every revolution of dial C the segment toothed wheel I. causes the tens dial D to
advance one figure, as herein before explained by reason of which the score is
calculated automatically. Suppose plain again makes 2 points (his score being
now 19) I take hold of peg E which is opposite figure 2 on cover F. F. and move
it round to 0 on cover F. F, as before, when the score will show 21 as the state of
the game for plain as seen through the opening in Cover.
The above appartus is only intended for marking games up to 50 points.
When 100 point games are required to be marked the dials are figured as shewn
at fig. 3 of the accompanying drawings.
When more than 100 point games are required to be marked three or more
dials are employed.
The small pin J (fig. 5) on dial D acts on a Counter L, or similar contrivance,
which gives the number of games played within the stated time.
In place of the wheels G. H & I to work the dial D. I prefer to have 10 pegs
or pins on the back of the dial D direct and acted upon by a spring catch or lever
fastened to the arbor of dial C.
Although this apparatus is described with reference to marking Billiards only it
is equally applicable for marking the score of other games.
Having now particulary described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
1st The employment of two dials or discs for each player, with their axles,
wheels, studs, pins and covers (or their equivalent) figured, combined, and arranged
so as to calculate the score automatically as substantially described and illustrated
on figs. 2, 4 & 5 of the accompanying drawings.
2nd The employment of two or more dials for each player with their axles,
wheels, studs, pins and covers figured, combined and arranged as substantially
described and illustrated by figs. 3, 5 & 1 of the accompanying drawings.
3rd The employment of 3 or more dials for each player, as substantially
described.
