PROVISIONAL SPECIFICATION.
Improvements in Dials for Recording the Progress of Lawn Tennis
and other Games.
1 WILLIAM COLBORNE BUTLIN of Leonard Stanley Stonehouse Gloucester, Engineer
do hereby declare the nature of this invention to be as follows:-
I make the face of the Dial of wood brass or other suitable material and so divide
the same that the upper portion of the Dial is a Record for one party or side playing
and the lower portion for the other party or side. 1 fix two fingers on revolving
centres and each of these centres comes close to but does not touch the centre of the
Dial the one being a little above and the other a little below the latter. Each finger
has a movement of a semi circle and points to figures or letters to mark the
game.
I make some of the said Dials large enough to serve as indicators to all the
players and for that purpose I adjust each of them upon a suitable stand or pole of a
suitable height, on the other hand I make some of the Dials very small and attach
them to the Racquet handles.

COMPLETE SPECIFICATION.
Improvements in Dials for Recording the Progress of Lawn Tennis
and other Games.
I, WILLIAM COLBORNE BUTLIN of Leonard Stanley, Stonehouse Gloucestershire,
Engineer, 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 :-
In making a Dial according to my invention I make the face thereof of brass, tin,
wood or other suitable material and I divide the same into two parts upper and lower
by painting staining or otherwise marking the surface of the dial. The upper and
lower portions may thus be used by the two parties to the game. On each portion
aforesaid I arrange a moveable finger. The axis of each finger I arrange upon the
dial the one a little above and the other a little below the centre of the dial. Each
finger has a movement of a little more than half a circle and the ends of the fingers
point to letters and figures as required to mark the game.
I make the said dial either for the purpose of fixing upon the handle of a
Tennis Racquet for example in which case the diameter is about 1 inch, or I make
the same on a larger scale in which case I affix a suitable stand for same and when
desired 1 place the same upon the lawn or other place where the game is being played
and so that the players may from time to time see the state of the game one person
recording the same by moving the fingers as desired.
To prevent the fingers moving round too freely I arrange a suitable washer to each
and when I affix a dial upon a racquet handle I make the dial of a convex and
concave shape the convex side being, then the outer one I am able by means of a
screw in the centre to fasten the dial more securely to the handle and to prevent its
moving round. The said washers may be of india rubber or other suitable material.
In the annexed drawings Fig. 1 shews a front view of the Dial with fingers A
and and centre screw B. The figures and letters marked thereon also shew the
usual scores for Tennis. Fig. 2 shews a sectional view of the dial as fixed to racquet
or post H. X is the dial cut from E to F fig. 1.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
The construction of a dial with upper and lower fingers thereon secured to a Tennis
racquet or post substantially as herein before described and set forth.
