IMPROVED GRASS MARKER TO BE USED IN LAWN-TENNIS & OTHER SIMILAR GAMES
Year: 1884

page_text: I ALEXANDER GOWANS Junior of Viewforth Edinburgh in the County of
Midlothian Scotland Assistant to India Rubber Manufacturers do hereby declare
the nature of my invention for AN IMPROVED GRASS MARKER TO BE USED IN
LAWN-TENNIS & OTHER SIMILAR GAMES to be as follows:-
The purpose for which the Machine is to be used is the marking of a white or
other distinctive line on grass, Lawn or other surface, to space out the courts
required in the Game of Lawn Tennis, or for any similar purpose.
According to my Invention the above object is effected in a much more simple
manner than by any machine at present in use The various parts are less likely to
get out of Order while the working of the Machine is so easy that a child may use
it-It is so constructed as to be portable, the various parts being easily separated
while its remarkable cheapness brings it within reach of all.
The Drawing explains clearly the manner of Working and the construction of the
Machine.
DESCRIPTION OF THE DRAWING.
Fig. 1 is an elevation shewing the Machine resting (when not in operation) on
the end of the handle and on the two legs and Wheel. The dotted level line a. b.
across the supply box shews the whitening or other marking liquid-The Spout c. is
so placed that the long handle may be raised to a convenient height for propelling the
Machine without discharging the contents of the supply box on to the Wheel. The
Wheel is of Wood covered on the Rim with an india rubber tire marked d. on
drawing-The Supply Box is of tin or other suitable metal and has three lugs
projecting from the bottom through which it is screwed to the frame.
Fig. 2. Shews the handle raised to the required height for discharging the liquid
through the spout c. on to the india rubber tire d. of the Wheel, down to the surface
which it is desired to mark-As the box is emptied the handle must be raised as
required.

page_text: Fig 3. is a plan looking down on top of frame and wheel but without the supply
box The handle e. is dovetailed into the frame at f and fixed by a brass thumb
screw the head of which is seen at g the nut being below. The dotted lines at h. h.
shew the screws fixed into wooden axle of wheel and bearing on rings ii attached
to the frame. The dotted circles at kk shew the position of the wooden rest legs.
Fig. 4. is a vertical section through supply box and handle shewing the frame
wheel and other parts in elevation-The shaded portion of supply box indicates
the liquid. The Nut of the thumb screw is seen in elevation at e--The screws h. h.
and bearing rings ii are also partly seen in elevation.
Fig 5. is a perspective sketch shewing the Machine in operation leaving the white
line on the grass.

page_text: I ALEXANDER GOWANS Junior of Viewforth Edinburgh in the County of
Midlothian Scotland Assistant to India Rubber Manufacturers do hereby declare
the nature of my invention for AN IMPROVED GRASS MARKER TO BE USED IN
LAWN TENNIS AND OTHER SIMILAR GAMES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The purpose for which the Machine is to be used is the marking of a white or
other distinctive line on grass lawn or other surface to space out the courts
required in the Game of Lawn Tennis or for any similar purpose.
The Drawings attached to my Provisional Specification N° 8173 dated the 26th
day of May 1884 are sufficient to fully describe and ascertain the nature of my
Invention.
The following is a description of the Drawings of the Machine.
Figure I is an elevation shewing the Machine resting when not in operation on
the end of the handle and on the two legs and Wheel-The dotted level line a. b.
across the supply box shews the whitening or other marking liquid-The spout c is so
placed that the long handle may be raised to a convenient height for propelling the.
Machine without discharging the contents of the supply box on to the Wheel-The
Wheel is of Wood covered on the rim with an india rubber tyre marked d on
drawing The supply box is of tin or other suitable metal and has three lugs
projecting from the bottom through which it is screwed to the frame.
Figure II shews the handle raised to the required height for discharging the
liquid through the Spout c on to the india rubber tyre d of the wheel down to the
surface which it is desired to mark. As the box is emptied the handle must be
raised as required.
Figure III is a plan looking down on top of frame and wheel but without the
Supply box-The handle e is dove-tailed into the frame at fand fixed by a brass
thumb screw the head of which is seen at g the nut being below. The dotted
lines at h h shew the Screws fixed into Wooden axle of wheel and bearing on rings i i
attached to the frame The dotted Circles at . k. shew the position of the Wooden
rest legs.
Figure IV is a vertical Section through Supply box and handle shewing the
frame, Wheel and other parts in elevation-The shaded portion of Supply box
indicates the liquid-The Nut of the thumb screw is seen in elevation at e-The
Screws h h and bearing rings i i are also partly seen in elevation.
Figure V. is a perspective Sketch shewing the machine in operation leaving the
white or other line on the grass.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st "The India Rubber Tyre" which is fixed on the bearing or carrying and
marking wheel is claimed as a feature of novelty in such marking Machines.
2nd The "handle is detachable "-this is claimed as a feature of novelty in such
marking machines.
13
3rd The "Frame as described and shewn comprises a cross bar and two bars
fixed at right angles into the said cross bar also two rest legs fixed into the said
cross bar which "Frame" is claimed as a feature of novelty.

page_text: 4th The Box which is attached on the top of the frame and lower end of the
handle has a Spout' "fixed on the end nearest the bearing or carrying and
marking Wheel which "Spout" is claimed as a feature of novelty.
5th The Mode of Construction and Method of Action of the machine as already
particularly described are claimed as features of novelty.
