COMPLETE SPECIFICATION.
Improvements in connection with Lawn Tennis Court Markers.
I, JAMES LUCAS Croxteth Drive Sefton Park Liverpool Gardener 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:-
This invention relates to lawn markers & consists of an airtight vessel so
constructed as to allow it to be filled by unfastening an air tight fitting cap,
when filled a valve at the bottom of vessel is opened and the marking material
allowed to flow out into the box of lawn tennis marker, to the required level
which level is maintained by self action, when the level is slightly lowered by
using the lawn tennis court marker, the vacuum of the air tight vessel is slightly
released and replaces the material in the lawn tennis court marker box at the
same rate as it is being used in marking lawn tennis court.
Referring to the annexed drawings.
Figure 1 is a plan of my invention.
Figure 2 side elevation of same.
a frame carrying the tank or reservoir à containing the marking material such as
white paint which is supplied to the extension or tray c. by means of the valve d.
when the rod e is depressed the valve d pivoted at f. is withdrawn from the
aperture 9. & may be retained in that position by the ring or catch piece h. The
marking material will thus maintain a constant levél until the contents of the
tank 6 are exhausted. is a drum or wheel supported up inclined planes j. by
means of spindle & bearing against the wheel. This drum i revolves in the
tray c & thus supplies the marking substance to the wheel which when the
apparatus is caused to travel, transfers the marking substance to the ground or
grass. m handle n air tight cap for filling the reservoir.
It will be seen that when the level of the marking substance in the tray c, falls
below the end of the tube 9, air will enter the reservoir & a fresh supply of
marking substance will flow from the tank into the reservoir c.
