PROVISIONAL SPECIFICATION.
An Improved Lawn Tennis Court Marker.
I, EDWARD BARNARD of Bird Street, Lichfield, in the County of Stafford,
Ironmonger, do hereby declare the nature of this invention to be as follows
--
This invention relates to the small hand-barrow employed for marking the
dimensions of the tennis courts on a lawn. My improved marker consists of a box
or pan with a wheel or wheels in front for conveying the apparatus from place to
place when not marking. It has also legs in rear for standing still.
The special feature in my marker is that it has the marking wheel immediately
under the pan which contains the fluid chalk or lime. This wheel projects partly

into the pan being enclosed in a recess or channel constructed for it.
channel or enclosure is a valve, which when opened allows the chalk mixture to fall
on the wheel. The opening of this valve is effected by a vertical rod or chain,
attached to the driving handle of the marker. This driving handle is so hinged or
pivotally attached to the pan that it can rise or fall a short space and when allowed
to fall it closes the valve. When lifted to its full height the valve is fully open.
The valve can thus at the option of the person using the marker be held open or
shut, or in any intermediate position, whereby the flow of the chalk can be regulated
as desired. This facility for regulating the supply of chalk or lime to the wheel,
is a peculiarity of my marker to which I attach much importance.
If preferred the driving handle can be fixed and the valve be operated by a
chain and lever with a rack attached to the handle, or in any other suitable way.
When the marker is being conveyed from place to place, the pan is lifted by the
driving handle, so that the marking wheel does not touch the ground, the valve rod
being detached from its pin on the handle if necessary, or the pan itself being held
up by a separate hook provided for this purpose, so that the valve shall be kept
closed.

COMPLETE SPECIFICATION.
An Improved Lawn Tennis Court Marker.
1, EDWARD BARNARD of Bird Street, Lichfield, in the County of Stafford,
Ironmonger, 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 is designed to supply a lawn tennis marker of simple construction
which will be efficient and inexpensive. It refers to the small hand barrow
employed to mark the dimensions of the tennis courts on a lawn.
My improved marker consists of a box or pan for holding the fluid whiting, and
which is mounted on a wheel or wheels for ready conveyance from place to place.
It has also the marking wheel placed at one end of the pan, and a handle by which
its movements are directed. The marking wheel has by preference a slightly
hollowed periphery, into which the whiting or fluid chalk is introduced.
This wheel projects partly into the pan, and the projecting part of the wheel is
covered or enclosed by a recessed channel formed in the bottom of the pan to
receive it. In or near this recess placed a small valve which when opened allows

page_text: the fluid to fall upon the wheel. The opening of this valve is effected by a vertical
rod or chain attached to the driving handle of the marker.
I will now describe the implement with reference to the accompanying drawing
in which
Fig. 1 shows an elevation in perspective of my improved marker with the valve
open.
Fig. 2 shows a sectional elevation of the article with the valve closed.
Fig. 3 shows a similar section with the valve open.
a, is the pan, b, the handle, c, a crossbar to which the valve chain or rod d, is
attached.
It will be seen that when the handle is lifted a sufficient distance, the valve is
opened, and the amount of opening can be thus adjusted, so that the flow of the
fluid chalk can be regulated as desired.
The handle is so hinged or pivotally attached to the pan, that it can rise or fall
a short space, and when allowed to fall it closes the valve. This method of
regulating the flow of chalk to the wheel is a special feature of my marker to which
I attach much importance. If preferred the handle can be fixed and the valve be
operated by a chain with lever and rack attached to the handle or in any other
suitable way.
Referring again to the drawing, e, is the valve in the bottom of the pan. is the
recess in which the wheel runs. 7, is the marking wheel with a hollowed periphery.
h, h, are the two edges or flanges on the face of the wheel. i, is one of the travelling
wheels on which the marker runs.
When the marker is being conveyed from place to place, the pan can be lifted
by the driving handle, so that the marking wheel does not touch the ground. To
prevent the valve opening, the valve rod or chain d, may be made detachable from
the crossbar, and another resting place may be provided for it lower down on the
handle.
Or, the pan itself may be held up by a separate hook or chain provided for the
purpose, so that the valve shall be kept closed.
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 :-
1. In a lawn tennis marker the general arrangement and combination of parts,
as herein described and set forth.

2. In a lawn tennis marker the regulable valve e, and the marking wheel with
recessed periphery, as herein described and set forth.
3. In a lawn tenuis marker the method of opening and closing the valve by
lifting or lowering the handle, as herein described and set forth.
