Year: 1882

page_text: LETTERS PATENT to Patrick Mara, of 100 Disraeli Road, Putney, in the
county of Surrey and Joseph Winson, of 211 Liverpool Road, in the county
of Middlesex for an invention of "AN IMPROVED BILLIARD MARKING AND
CHECKING APPARATUS
PROVISIONAL SPECIFICATION left by the said Patrick Mara & Joseph
Winson at the Office of the Commissioners of Patents on the 13th April
1882.
PATRICK MARA of 100 Disraeli Road, Putney, in the county of Surrey, and
JOSEPH WINSON of 211 Liverpool Road in the county of Middlesex "AN IMPROVED
BILLIARD MARKING AND CHECKING APPARATUS
"
This invention relates to the construction of an improved billiard marking and
checking apparatus whereby the marking the points scored automatically registers
or records the number of games played.
A suitable method of carrying out our invention consists in providing a suitable
case baving a number of dials, faces or indices, each dial or the like is provided
with a hand or other indicator suitably connected with a combination of toothed
wheels so arrauged and combined that as the hands or their equivalents are moved
or operated to record the scores or number of points made, the hand or other
indicator of the dial serving to record or register the number of games played, is
also moved and the number of games played is thereby automatically recorded.
Suitable means, such as a ratchet wheel or other arrangement, are provided to
prevent the hands or other indicators being moved backwards.

by the said Patrick Mara & Joseph Winson in the Great Seal Patent Office
on the 13th October 1882.
PATRICK MARA, of 100 Disraeli Road, Putney, in the County of Surrey, and
JOSEPH WINSON, of 211, Liverpool Road, in the county of Middlesex "AN IMPROVED
BILLIARD MARKING AND CHECKING APPARATUS
"
This invention relates to the construction of an improved billiard marking and
checking apparatus whereby the number of games played is automatically
registered by operating a finger or pointer which is used to mark the points as
they are scored.
In carrying out our invention we provide-a-suitable-face-having-two-dials-or-
faces marked with divisions and having a hand for indicating on the said dial the
number of games played; the said hand is operated as hereinafter described.
In the front of the said case are two slots (one for each dial); in each of the said
slots slides the pointer constructed as hereinafter described and corresponding with
__cach_slot_is_an_index of the ordinary description on which are marked, written or
painted the figures representing the points of the game.
The pointers consist of a finger on the end of a square slide which slides in the
herein before described slot in the case of the apparatus; on the said slide is a
rectangular shaped-plate-which-bears-against-the-back-of-the-herein before described-
slot and with the finger, which is in front of the slot, guides the slide in the slot.
Through the said square slide (which extends a certain distance beyond the herein-
before described rectangular plate) is drilled a hole in which is fitted a spindle
provided at its front end with a knob and at the other end behind the rectangular
plate the said spindle carries a small plate which we term the reversible plate.
The said reversible plate is provided with a spring or click, the said spring or click
taking into or gearing with the teeth of a rack at the back of the slot in the case
of the apparatus. From the back of the said guide plate project two pins which
act as stops and prevent the reversible plate being turned more than half a rovo-
lution. At each end of the rack is fitted a turn table having ears or flanges into
which the reversible plate and click slide when at the ends of the slot. The turn-
table at the right hand end of the slot and between it and the dial, is connected
with a train of toothed wheels so that if the reversible plate be turned half a
revolution by means of the knob in front of the pointer, the turntable will be
operated and thereby move the said wheels so as to operate the hand of the
corresponding dial and cause the hand to move over one division of the dial.
From this construction of apparatus it will be evident that if the pointer be at
the left hand end of its slot it can be moved forward to mark on the index the
progress of the game the rack allowing the catch and therefore the pointer to be
moved from left to right but not in the reverse direction:
Upon reaching the end of the slot and the rack, the knob is turned half a revo-
lution thereby turning the reversible plate and turntable as hereinbefore described
and causing the hand on the dial to score one game (or the number of points
on the index); the reversible plate in being turned carries with it the spring or
click which being thus reversed will allow the pointer and reversible plate to be
moved back to the other or starting end of the slot and the knob being then turned
a half revolution in the opposite direction to that hereinbefore described the
pointer will be again in the position to bo moved forward to score as before,
and so on.

page_text: Having thus described our invention and the manner of performing the same
what we claim is :-
Firstly. The improved billiard marking and scoring apparatus constructed and
operating as hereinbefore described.
Secondly. In a billiard marking and scoring apparatus the use of a pointer
having a reversible plate and spring or click constructed and operating in the
manner and for the purposes hereinbefore described.
In Witness whereof We the said Patrick Mara and Joseph Winson have hereto
set our hands and seals this thirteenth day of October in the year of our
Lord one thousand eight hundred and eighty two.
