Lawn Tennis Game Recorder or Marker.
WILLIAM POTTER Shop Fittings Manufacturer 160/1 Aldersgate Street
London do hereby declare the nature of this invention to be as follows:-
I take a piece of thin sheet metal about one & half inches square, and shape it
in circular form. A margin of a quarter inch of this circle I divide into fourteen
parts. On the upper half I engrave numerals 0, 1, 2, 3, 4, 5, 6 with the words.
Games Won, and on the lower half similar numerals with the words Games Lost.
Each numeral is then separately punched, embossed or raised up from the flat a
height of fully one quarter inch. The article is now in form of a clock dial with
fourteen protuberances. I now affix two moveable hands or pointers to the centre
of the plate or dial, these hands have flat pear shaped ends, I perforate these flat
ends with holes the exact size of the raised protuberances on which the numerals
are engraved, so that when either hand or pointer is moved to the right or left, it
automatically adjusts itself by dropping over the protuberance required, and
remains fixed until altered.
The lawn tennis marker thus finished enables players to keep a perfect record
of the game.
It may be rivetted to a band of leather and worn on the wrist, or
serewed to a racquet or carried loosely in the pocket.
Dated this 28th day of April 1894.

London 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 :-
I take a piece of thin sheet metal about one and a half inches square, and shape
it in circular form. A margin of a quarter of an inch of this circle I divide
into fourteen parts. On the upper half of circle I engrave numerals 0, 1, 2, 3, 4, 5, 6
with the words Games Won. On the lower half I engrave similar numerals with
the words Games Lost. Each numeral is then separately punched embossed or
raised up from the flat, a height of fully one quarter of an inch, (see Fig. 1 on
drawing). I now prepare two moveable hands or pointers (see Fig. 2) these
hands have flat pear shaped ends. I perforate these flat ends with holes the exact
size of the raised protuberances on which the numerals are engraved, (see Fig. 3).
I now affix the two moveable hands or pointers to the centre of the dial (see
Fig. 4) the bands or pointers readily move to the right or left automatically
adjusting themselves by dropping over the protuberance required, remaining fixed
and immoveable until altered. The lawn tennis marker thus finished enables
players to keep a perfect record of the game. It may be rivetted to a band of
feather and worn ou the wrist or waist, screwed to a racquet or carried in the
pocket.
