Improvements in Means or Apparatus for use in Marking Courts for
the Game of Lawn Tennis, and for other like purposes.
We FREDERICK HENRY AYRES, of 111 Aldersgate Street, in the City of
London, Manufacturer and HARRY PITTS of 31 Wycombe Road, Coleraine Park,
Tottenham, in the County of Middlesex, Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to means or apparatus for use in marking courts for the
playing of the game of lawn tennis and for other like purpose wherein a liquid
generally chalk and water is used.
In most of the arrangements known to us the distribution of the marking matter
is effected either by a band stretched and covered with whitening matter which by
a jerk is deposited, or if delivered from a perambulatory cistern mounted on wheels
such delivery has been effected by causing a band to travel over and under wheels
which press it on and cause it to mark the ground whilst it is also caused to pass
through the liquid matter in the trough or cistern or the liquid matter has been
lifted by a wheel or wheels with or without a duct or channel onto a wheel which
marked the ground.
According to our improved construction we effect direct delivery by gravitation
from the cistern or trough itself onto the delivery wheel or roller below and so
avoid complication or cost by the intervention of any intermediate feed roll, band
or channel. In the bottom or adjacent part of the reservoir or trough we locate a
valve adapted to be raised from its seat by a chain or cord for exit of marking
matter and to fall back to its seat to close the passage by its own weight when
The valve
released, or it may be constantly borne to its seat by spring pressure.
should be provided with a tail piece passing through the valve passage so as
to aid in keeping such passage clear of the thicker marking matter and prevent
unequal delivery, or stoppage of flow. In proximity to this tail piece or below
the valve passage is suitably mounted a wheel, roller or equivalent supporting
part onto which the matter is delivered and pressed on to the ground or lawn so as
to mark it in the line of travel of such part.
A convenient construction constituted as described consists of a tank on two
larger leading wheels and a smaller middle following and marking wheel with a
convenient handle springing from the rear of the tank.

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:-

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a side view
Fig. 2 a rear view
Fig. 3 a plan view and Fig. 4 a separate view of the valve in elevation.
According to our improved construction we effect direct delivery by gravitation
from the cistern or trough a itself onto the delivery wheel or roller below and so
avoid complication or cost by the intervention of any intermediate feed roll band or
channel. In the bottom or adjacent part of the reservoir or trough a we locate a valve c
shewn enlarged at Fig. 4 adapted to be raised from its seat c by a chain or cord c²
for exit of marking matter and the said valve c being adapted to fall back to its
seat c' to close the passage by its own weight when released, or it may be constantly
borne to its seat by spring pressure. The valve should be provided with a tail
piece passing through the valve passage e so as to aid in keeping such passage
clear of the thicker marking matter and prevent unequal delivery, or stoppage
of flow. In proximity to this tail piece c³ or below the valve passage is suitably
mounted the wheel broller or equivalent supporting part onto which the matter is
delivered and pressed onto the ground or lawn so as to mark it in the line of travel
of such part.
A convenient construction constituted as described consists of a tank on two
larger leading wheels and a smaller middle following and marking wheel with a
convenient handle springing from the rear of the tank as shewn but the form of
the parts and other of the details may be varied.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In apparatus for use in marking courts for the game of lawn tennis and for other
like purposes the combination or arrangement and use of a tank reservoir_or
cistern for marking liquid, a delivery or marking wheel or its equivalent and a
valve and valve passage for controlling direct supply of said liquid from reservoir
to delivery roller, substantially as set forth.
