I, ALEXANDER MELVILLE CLARK; of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN BILLIARD MARKERS" a communication to me from abroad by Thomas Clarke
Jenkins of Wellington, New Zealand, Accountant, to be as follows:―
This Invention relates to a combined marker and register of the number of
games played at billiards.
The invention consists in a box provided with a hinged or sliding cover having
two longitudinal slots, behind each of which a roller bearing a series of rows of
numerals is journalled each. roller being provided with a shaft and a handle for
revolving. the roller the distance of one row of numerals as the number of points
made increases, so that the rows of numerals shall successively show in the slots in.
the cover.
5-
The invention further consists in mechanism for releasing the rollers and
permitting springs connected with the same to throw them back so that the first
rows of numerals will show through the slots.
The invention further consists in three counting discs provided with mechanism
for operating them from the two rollers above mentioned, which counting discs are
arranged behind a slot in the cover.
I will describe the apparatus with reference to the accompanying drawings.
A is the box or case having the door or cover B in which are two longitudinal
slots C and C and two grooves c and c¹ in which tenons which are secured to the
pointers D and D¹ are received the points of said pointers projecting over the
and lower edges-of-the-slots C and C₁ respectively.
пррег
There is at one end of the cover a solid part E having a slot covered with glass,
and through which the game register shows. F F¹ are the rollers which bear five
rows of numerals from 0 to 99 inclusive, the first row containing the numerals from
0 to 19, the second from 20 to 39, the third, from 40 to 59, the fourth, from 60 to 79,
and the fifth, from 80 to 99 inclusive, and in the middle of the third row the
numeral 50 is located, which is made of a different color from the rest or is arranged
in such a manner that it can easily be distinguished from the other numerals. The
rollers F and F¹ are each provided on their outer end with an aperture into which
short shafts respectively pass; while shafts also pass into the opposite ends of said
rollers F, F. The first shafts are journalled in a frame projecting from the inner
surface of the bottom or back of the box and are furnished at their outer ends with
crank handles g and g¹ for turning the said shafts and are surrounded by springs
for throwing them back after they have been turned. To each shaft an arm is

page_text: .
-
attached on the outer end of which is pivoted a pawl which is pressed by a spring
against a ratchet wheel mounted on the end of each of the rollers whereby said
rollers will be revolved the distance of one tooth of the ratchet wheel by turning
the corresponding shaft. The pawls also rest on cams loosely mounted on the shafts
between the arms and the ratchet wheels on the rollers. Each cam has a notch and
is provided with a spring pressed.pawl. The cams on the two shafts are connected
at their lower ends by a bar from which a pin passes through a slot in the lower
end of an arm formed on the end of a shaft also journalled in the end of the box
and which shaft is provided at its outer end with a handle. L'. This shaft is
thrown back after it has been turned by means of a spring and is prevented by stop
pins from turning back too far.
If the player makes a certain number of points between 1 and 10 he moves his
pointer opposite the proper number on the roller For F. If this number exceeds 20
he pulls down the crank handle g.or g¹ and moves the pointer to the number of
units above 20 on the roller. Every time the crank handle g or g¹ is turned the
corresponding pawl engages with the teeth of the ratchet wheel and turns the roller
the distance of one tooth. If the handle is released the spring throws the handle
back and the pawl slides back over the teeth of the ratchet wheel, and so on.
Every time 20 units have been made, the roller is turned to expose a new line of
figures in the slots. A game can be played to fifty or to one hundred points or to
thirty or sixty, as may be customary, and the numbers in the rows on the rollers
can be arranged in different manners according to the way of playing and marking.
After a game has been played, and all the points counted, it is necessary to throw
the rollers back again so that the first row of numbers will show. This is
accomplished by means of springs M held in circular projections on the opposite
ends of the rollers which springs have one end secured on the inner surface of the
circular projections and the outer end secured on the shafts H or H¹ of the rollers,
but in order to permit the springs to throw back the rollers the pawls must be
disengaged by lifting the bar connecting the cams whereby the cams will be moved
in such a manner as to raise the pawls and disengage them from the ratchet
wheels.
The number of games played is automatically registered by means of three rollers
or discs N', N³, N³, mounted loosely on a shaft N, next the inner ends of the
rollers F, F. The discs are each provided on their peripheries with the numbers 0 to 9
inclusive. Each disc is provided on its outer surface with a ratchet wheel O and
a short distance from the ratchet wheel on the disc Na disc.P is held rigidly on
shaft N on the outer surface of which disc is pivoted a pawl P' having at one end
a pin adapted to pass into the notches between the teeth of the ratchet wheel O,
the disc P being provided with a notch P³ into which the pin Ps can pass, so that
it will not project beyond the edge of the disc P Between the ratchet wheel O and
the corresponding disc P, a lever Q is loosely mounted on the shaft N which lever
is provided at one end with a pawl (not shown) which is pressed against the teeth
of the ratchet wheel by a spring. The opposite end of the lever is forked, and into
the fork passes a pin projecting from a bar connecting two rocking arms or levers
pivoted on a suitable frame on the front surface of the back of the box, which arms
are pressed toward the bottom of the box by springs Cams S on the end of the
rollers F and F¹ are adapted to act on the arms and thus move the bar upward.
On the inner surface of each diso N¹, and N' a disc T is secured, on which a pawl
lever T¹ acted on by a spring is pivoted which pawl lever is provided at its free
end with a pin T adapted to engage with the teeth of the ratchet wheel O of the
adjoining disc which pin T' also passes into a notch t in the edge of the adjoining
disc P. On the outer surface of the disc N₁ the lever Q is arranged between the
disc P and the ratchet wheel O; but in the remaining discs N' and N, the disc-P
and the ratchet wheel O adjoin each other. Each disc P is provided with a pawl
lever as described, with a notch t, and the pin T' on the lever T¹ pivoted on the
disc T on the inner surface of the first disc N, passes into the notch t and engages
with the ratchet teeth of the wheel O on the second disc N', and likewise the pin T
1

page_text: on the pawl lever T2 pivoted on the disc T of the second disc N' passes through its
notch and engages with the teeth of the ratchet wheel O of the third disc N³.
As has been previously described one of the crank handles g or-g' must be turned
as soon as twenty points have been made, or as soon as the number of points has
been made, that is on one of the rows of numbers on the roller F or F', but as soon
as one of the rollers is turned the distance of one row of numbers the cam S on the
corresponding roller begins to act.on the arm and moves the same upward, thereby
moving the forked end of the lever Qin the same direction and thus causing the
pawl on the opposite end of the lever to revolve the ratchet wheel O on the first
number disc N¹ the distance of one tooth. The cams S are so constructed and
arranged that if the roller is revolved, to show successively the five rows of figures
on the same, the cams will by means of arms cause the lever Q to move the ratchet
wheel O the distance of two teeth; that is, when the roller is turned to remove the
first row of numerals from under the slot, the disc N¹ is moved the distance of one
number; when the roller is turned to move the second row of numerals from under
the slot, the disc N¹ is not moved; if the roller is turned the third time, removing
the third row of numerals from under the slot the disc N' is again moved one
number, and when the roller is turned the fourth time the disc N¹ is not moved.
If then, the handle L' is turned it releases the roller and permits it to fly back, the
rods and the connecting bar are moved downward ready for another registration.
After the disc N¹ has made nine-tenths of a revolution, the pin T on the pawl
lever T¹ of the disc T on the inner surface of the disc N' engages with a tooth of
the wheel O of the second disc N2 and revolves the same the distance of one tooth.
After the second disc 'N' has made nine-tenths of a revolution the third disc N' is
moved in a like manner, and so on. The disc Nis successively moved the distance
of ten teeth, and during that time, the pin T* on the disc T on the inner surface of
the disc N rests on the edge of the disc P on the disc N*; but after the disc N¹ has
been revolved the distance of nine teeth, the pin T of the disc T¹ drops into the
notch t of the disk P on the disc N thus permitting the pin T to engage with the
teeth of the ratchet wheel O on the second disc N³, thus revolving the said disc
the distance of one tooth, but as soon as the said movement has been made, by the
disc N', the pin T2 of the disc N¹ slides up on the spring to on the end of the pawl
lever P¹ of the disc P, opposite the one provided with the pin P2, as the end provided
with the pin P³ is pressed outward by a tooth of the ratchet wheel O of the disc N
the spring is pressed down to prevent the pin T' to pass on it. As soon as the
disc N has been revolved the distance of one tooth, the pin P' on the end of the
lever P¹ of the disc P on the disc N' snaps back into the notch P³, thereby raising
the spring and pin T on the lever T¹ of the disc N₁, thus enabling the said pin Tí
to travel on the edge of the disc P of the adjoining disc N°.
In order to understand the above operation, it must be kept in mind that the.
discs P are all rigidly mounted on the shaft N, the ratchet wheels O are connected
with the discs N₁, N and N³ on one side, and the discs T on the opposite side; the
discs N, N and N³, the ratchet wheels O and the discs T being loosely mounted on
the shaft N. -
=
One of the special features of this apparatus is that, as soon as one of the
shafts For F is turned, the disc N¹ is moved the distance of one number, thus
making it impossible for a person to play more than twenty points without
registering a game, for a person might well make twenty points and then run out
on a single run without requiring any further registering of points, then no game
would be registered if the cams S were not so constructed as to move the number
discs at the first movement of the roller F or Ft.

53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
BILLIARD MARKERS" (a communication to me from abroad by Thomas Clarke
Jenkins of Wellington, New Zealand Accountant,) and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention relates to a combined marker and register of the number of
games played at billiards.
The invention consists-in-a-box-provided with a hinged or sliding cover having.
two longitudinal slots behind each of which a roller bearing a series of rows of=
numerals is journalled, each roller being provided with a shaft having a handle for
revolving the roller the distance of one row of numerals, as the number of points
made increases, so that the rows of numerals shall successively show in the slots in
the cover.
:
The invention further consists in mechanism for releasing the rollers and
permitting springs connected with the same to throw them back so that the first
rows of numerals will show through the slots.
The invention further consists in three counting discs provided with mechanism
for operating them from the two rollers above mentioned, which counting discs are
arranged behind a slot in the cover.
The invention also consists in various parts and details and numerous com-
binations of the same, as will be fully described and set forth hereinafter.
.

The box A is provided in its front with a hinged or sliding door or cover B
provided with two longitudinal slots C and C¹ and with two grooves c and c¹, in
which grooves tenons pass which are secured on pointers D and D¹, the points of
which project over the upper and lower edges of the slots C and C₁ respectively,
the pointers being held to slide on the outer surface of the cover B. The slots C
and C¹ do not extend from one end of the cover to the other, but at one end of the

page_text: cover, there is a solid part E having a slot E¹ covered with glass and through
which the game register shows. Beneath each slot C and C¹ a roller For F¹ is
journalled, parallel with the said slot, on which rollers five rows of numerals,
from 0 to 99 inclusive, are arranged, the first row containing the numerals 0 to 19,
the second from 20 to 39, the third from 40 to 59, the fourth, from 60 to 79, and
the fifth, from 80 to 99, inclusive, and in the middle of the third row the
numeral 50 is located, which is made of a different color from the rest, or is
arranged in such a manner that it can easily be distinguished from the other
numerals. The rollers F and F are each provided on their outer end with an
aperture into which short shafts G and G¹ respectively pass; that is the shaft G
passes into the end of the roller F and the shaft. G¹ into the end of the roller F¹.
Shafts Hand H pass into the opposite ends of the rollers F F¹. The shafts G, G¹
are journalled in a frame I projecting from the inner surface of the bottom or back
of the box, and are provided at their outer ends with crank handles g and g¹ for
turning the said shafts. The shafts are surrounded by springs 98 and 9³ for
throwing them back after they have been turned. On each shaft G and G¹, an
arm G is attached, on the outer end of which a pawl G³ is pivoted, which is
pressed by a spring G against a ratchet wheel J mounted on the end of a roller F
or F, whereby the roller will be revolved the distance of one tooth of the ratchet
wheel J, by turning the corresponding shaft. The pawls G³ also rest on cams K
loosely mounted on the shafts G and G¹, between the arms G' and the ratchet
wheels J on the rollers. Each cam has a notch K¹ and against each cam a pawl J¹
rests, which is acted upon by a spring, to press it against the edge of the cam.
The cams on the two shafts are connected at their lower ends by a bar K' from
which a pink passes through a slot in the lower end of an arm L formed on the
end of a shaft L' also journaled in the end of the box in the same manner as the
shafts G and G¹, which shaft L is provided at its outer end with a handle L³.
A spring g' acts on the shaft L' and throws it back after it has been-turned...
If the player makes a certain number of points between 1 and 19, he moves his
pointer D or D¹ opposite the proper number on the roller F or F¹. If this number
exceeds 20, he pulls down the crank handle g or g¹ and moves the pointer to the
number of units above 20 on the roller. Every time the crank handle g or g¹ is
turned, the corresponding pawl G³ engages with the teeth of the corresponding
ratchet wheel J and turns the corresponding roller, the distance of one tooth. If
the handle is released, the spring g or g³ throws the handle back, and the pawl G³
slides back over the teeth of the ratchet wheel, and so on. Every time 20 units
have been made, the roller is turned to expose a new line of figures in the slots C
or C. A game can be played to fifty or to one hundred points, or to thirty or
sixty, as may be customary, and the numbers in the rows on the rollers can be
arranged in different manners according to the way of playing and marking.
After a game has been played, and all the points counted, it is necessary to throw
the rollers back again, so that the first row of numbers will show in the slot C
or C. This is accomplished by means of springs M, held in circular projections M
on those ends of the rollers opposite the ones provided with the ratchet wheels J,
which springs have one end secured on the inner surface of the circular projections
and the outer end secured on the shafts H or H' of the rollers; but in order to
permit the springs to throw back the rollers, the pawls G³ must be disengaged by
turning the shaft L' to lift the bar K' connecting the cams K whereby the cams K
will be moved in such a manner as to raise the pawls G and disengage them from
the ratchet wheels J. The handle L' is prevented from swinging back too far by
suitable stop pins.
The number of games played is automatically registered by means of three
rollers or discs N¹, N³, No, mounted loosely on a shaft N, next the inner ends of
the rollers F, F, that is, at the ends of these rollers. opposite the ones on which the
ratchet wheels J are mounted. The discs N1, N2 and N³ are each provided on their
peripheries with the numbers 0 to 9 inclusive. Each disc is provided on its outer
surface with a ratchet wheel 0 and. a short distance from the ratchet wheel on the

page_text: disc N¹, a disc P is held rigidly on shaft N, on the outer surface of which disc a
pawl P¹ is pivoted having at one end a pin P2 adapted to pass into the notches
between the teeth of the ratchet wheel O, the disc P being provided with a notch Ps
into which the pin P2 can pass, so that it will not project beyond the edge of the
disc P. Between the ratchet wheel and the corresponding disc P a lever Q is
loosely mounted on the shaft N, which lever is provided at one end with a pawl Q'
which is pressed against the teeth of the ratchet wheel by a spring Q. The
opposite end of the lever Q is forked and into the fork passes a pin R projecting
from the bar R¹ connecting two rocking arms or levers R³ pivoted on a suitable
frame on the front surface of the back of the box, which arms are pressed towards
the bottom of the box by springs R. Cams S on the end of the rollers F and F¹
are adapted to act on pins S' on the arms R³ and thus move the bar R¹ upward."
On the inner surface of each disc N¹ and N, a disc F is secured, on which a pawl
lever T¹ acted on by a spring T is pivoted, which pawl lever is provided at its free
end with a pin T' adapted to engage with the teeth of the ratchet wheel O of the
adjoining disc, which pin T2 also passes into a notch t in the edge of the adjoining
disc P. On the outer surface of the disc N', the lever Q is arranged between the
disc P and the ratchet wheel O; but in the remaining discs N' and N³, the disc P
and the ratchet wheel O adjoin each other. Each disc P is provided with a pawl
lever P¹ as described, with a notch t, and the pin T' on the lever T¹ pivoted on the
disc T on the inner surface of the first disc N1, passes into the notch t and engages
with the ratchet teeth of the wheel O on the second disc N' and likewise the
pin T on the pawl lever T' pivoted on the disc T of the second disc N* passes
through its notch t and engages with the teeth of the ratchet wheel-O-of-the-third-
disc N³.
As has been previously described, one of the shafts G or G' must be turned as
soon as twenty points have been made, or as soon as the number of points has
been made, that is on one of the rows of numbers on the roller For F¹; but as
soon as one of the rollers is turned the, distance of one row of numbers, the cam S
on the corresponding roller begins to act on the pin S₁ of the corresponding arm R³
and begins to move the same upward, thereby moving the forked end of the
lever Q, Figure 5, in the same direction, and thus causing the pawl Q on the
opposite end of the lever Q to revolve the ratchet wheel O on the first number
disc N¹ the distance of one tooth-The cams S are so constructed and arranged
that if the roller is revolved to show successively the five rows of figures on
the same, the cams will by means of arms R$ and R¹ cause the lever Q to move
the ratchet wheel O the distance of two teeth; that is when the roller is turned to
remove the first row of numerals from under the slot, the disc N' is moved the
distance of one number; when the roller is turned to move the second row of
numerals from under the slot, the disc N¹ is not moved; if the roller is turned the
third time removing the third row of numerals from under the slot, the disc N¹ is
again moved one number, and when the roller is turned the fourth time the disc N'.
is not moved. If then, the handle L2 is turned, it releases the roller and permits
it to fly back, the springs R* throw the rods R¹ and the connecting bar downward,
ready for another registration. After the disc N¹ has made nine-tenths of a
revolution, the pin T2 on the pawl lever T of the disc T on the inner surface of the
disc N¹, engages with a tooth of the wheel O of the second disc N, and revolves
the same the distance of one tooth. After the second disc N' has made nine-tenths
of a revolution, the third disc N³ is moved in a like manner, and so on. The
disc N¹ is successively moved the distance of ten teeth, and during that time, the
pin T on the disc T on the inner surface of the disc N¹ rests on the edge of the
disc P on the disc N; but after the disc N¹ has been revolved the distance of nine
teeth, the pin T of the disc T¹ drops into the notch t of the disc P on the disc N,
thus permitting the pin T to engage with the teeth of the ratchet wheel O on the
second disc N*, thus revolving the said disc the distance of one tooth. But as soon
as the said movement has been made by the disc N2, the pin T* of the disc N'
slides up on the spring t³ on the end of the pawl lever P¹ of the disc P, opposite

page_text: the one provided with the pin P, as the end provided with the pin P' is pressed
outward by a tooth of the ratchet wheel O of the disc N³, the spring is pressed
down to prevent the pin T to pass on it. As soon as the disc N* has been révolved
the distance of one tooth, the pin P' on the end of the lever P¹ of the disc P on the
disc N snaps back into the notch P³, thereby raising the spring t³ and pin T on
the lever T¹ of the disc N¹, thus enabling the said pin T' to travel on the edge of
the disc P of the adjoining disc N³.
In order to understand the above operation, it must be kept in mind that the
discs P are all rigidly mounted on the shaft N, the ratchet wheels O are connected
with the discs N₁, N° and N' on one side, and the discs T on the opposite side; the
discs N1, N2 and N³, the ratchet wheels O and the discs T being loosely mounted
on the shaft N.
One of the special features of this apparatus is that, as soon as one of the
shafts G or G¹ is turned, the disc N¹ is moved the distance of one number, thus
making it impossible for a person to play more than twenty points without
registering a game, for a person might well make twenty points and then run out
on a single run without requiring any further registering of points, then no game
would be registered, if the cams S were not so constructed as to move the number
discs at the first movement of the roller F or F¹.
