PROVISIONAL SPECIFICATION.
Improved Apparatus for Marking Out Lawn Tennis Courts or for
analogous purposes.
I WILLIAM JACKSON of Thorn Grove, Mannofield, Aberdeen, North Britain,
Engineer do hereby declare the nature of my invention to be as follows:--
My invention has for its object to provide a simple and efficient apparatus by
means of which dry granular or powdered material (such as sawdust grains, or
sand for instance) can be deposited in the required manner upon the ground 'to
mark out lawn tennis courts or to effect analogous markings. An apparatus
constructed according to my invention consists of a receptable for the sawdust or
the like beneath which is a passage or channel having an aperture or apertures
beneath for the outlet of the sawdust or the like. The said aperture or apertures
is or are provided with a trailing slide formed of cheek plates which slide upon
the ground and form guides and shields for depositing the sawdust or the like
in the required manner for facilitating the guiding of the apparatus in the requisite
direction and for protecting the sawdust or the like from the wind whilst being
deposited. The passage or channel through which the sawdust or the like passes
from the receptacle is provided with a stirrer or agitator and the apparatus is
provided with a wheel or wheels upon which it can be conveniently moved along
and from which by suitable gearing the stirrer or agitator is driven. The apparatus
may be provided with feet or lateral extensions to support it sideways.

Improved Apparatus for Marking Out Lawn Tennis Courts or for
analogous purposes.
I WILLIAM JACKSON of Thorn Grove, Mannofield, Aberdeen, North Britain,
Engineer, do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention has for its object to provide a simple and efficient apparatus by
means of which dry granular or powdered material (such as sawdust, grains, chalk,
lime, or sand for instance) can be deposited in the required manner upon the ground
to mark out lawn tennis courts or to effect analogous markings. An apparatus
constructed according to my invention consists of a receptable for the sawdust or
the like beneath which is a passage or channel having an aperture or apertures
beneath for the outlet of the sawdust or the like. The said aperture or apertures
is or are provided with a trailing slide formed of cheek plates which slide upon the
ground and form guides and shields for depositing the sawdust or the like in the
required manner for facilitating the guiding of the apparatus in the requisite
direction and for protecting the sawdust or the like from the wind whilst being

deposited. The passage or channel through which the sawdust or the like passes
from the receptacle is provided with a stirrer or agitator and the apparatus is
provided with a wheel or wheels upon which it can be conveniently moved along
and from which by, suitable gearing the stirrer or agitator is driven.
apparatus may be provided with feet or lateral extensions to support it sideways.
The accompanying drawings represent an apparatus constructed according to my
invention.
The
Fig. 1 is a front elevation. Fig. 2.is a side elevation. Fig. 3 is a plan and
Fig. 4 is a vertical section.
A is a receptacle containing the material to be deposited such as sawdust for
example. The said receptacle has an opening. at bottom a beneath which is fitted
the passage or channel B the lower end of which is preferably semi-circular and
has in it an opening E., The, said, passage or, channel is preferably somewhat
wider at bottom than at top to prevent the material from jamming therein. On to
the lower end of, the said passage or channel B are secured castings consisting of
portions G fitted to be bolted or otherwise secured to the said passage or channel B
and, cheek plates F forming the trailing slide which bears on the ground and forms a
means of defining the line made by the deposited material and prevents the said
material from being disturbed by the wind whilst, being deposited.
The said castings also have forward extensions f carrying the axle of the wheel J
and, the centre pink of the wheel K. D is a stirrer or agitator mounted in the
lower, part of the passage or channel B and consisting of prongs projecting, from
the.axis C which axis extends to outside and has fixed to it a spur pinion which
engages with the intermediate spur, wheel K driven by a spur wheel K2 on the axis
of the wheel J so that when the said wheel J. travels motion is imparted to the said
stirrer or agitator D: which causes the material to pass out from the opening E in a
continuous manner.
Hare lateral, extensions from the casting forming fect to assist in supporting
the apparatus.
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 :-
Apparatus for marking out lawn tennis courts or for analogous purposes the said
apparatus being arranged and constructed substantially as herein before described
and illustrated by the accompanying drawings.
