We JAMES MCHARDY Dollar North Britain Scientific Expert, and ROBERT BRAND
Hebron Bank, Canaan Lane Edinburgh, India Rubber Merchant, do hereby declare
the nature of this invention to be as follows:-
In carrying this Invention into practice we construct our Marker in such a manner
as that-
(a) The last drop of the marking liquid may be taken up.
(b) The marking liquid shall not be liable to spill.
(c) By driving the machine in one or other direction, thick or thin marking may be
accomplished, irrespective of the thickness of the marking liquid.
(d) The Well may be covered in by a lid, or the belt may be made to act as a lid:
or, the belt may be made to act as a lid, at one end, whilst a lid proper may be made
to cover up the other end of the Well.
(e) The belt shall be made of an absorbent material instead of India Rubber, but
this or any material may be used if preferred.
() When the marker is placed in a given direction no guiding will be necessary
to keep it in a straight line, whether upon even or uneven ground.
These conditions may be fulfilled, somewhat in the following manner.
(a) The Well shall be a deep one, instead of the shallow well of ordinary markers;
and, being tapered, longitudinally, from convenient dimensions at the top, to the apex
of a triangle, or to the arc of a circle at the apex of a triangular figure, at the bottom,
the belt, passing over a roller at the bottom of the said Well, shall use up the marking
liquid, to the last drop, notwithstanding any possible vibration of the machine in
passing over the ground.
(6) The Well being made narrow at the top (or throughout its dimensions) the belt
may become by the arrangement of rollers-(hereinafter mentioned) in itself a kind of
lid to prevent the spilling of the liquid; or, a lid or lids may be used for this purpose,
as we may find it convenient.
(c) By placing a roller at one of the upper ends of the Well, another at the bottom
of the Well, a third at any convenient point near the upper edge of the Well, and
using a large driving or marking wheel, the belt may be so arranged, that in working
the machine with the large wheel foremost, the belt shall pass directly from the Well
over the roller, at, or near the upper edge of the Well, out over the roller at the end,

page_text: (but not touching or interfering with this latter roller) thence to the large wheel and
the ground, without having had its more whitened surface disturbed between the time
of leaving the Well and coining to its work. In this way, a thick coat of colouring
liquid is laid down, and the belt then proceeds directly upwards and back to the liquid
in the Well, over the beforementioned roller at the end of the Well.
:
By working the machine with the large wheel behind, the opposite effect will be
produced for, the belt will, in that case, pass over the roller at the end of the Well,
which will wring out a portion of the marking liquid before allowing it to be fed upon
the marking wheel, and a lighter mark upon the ground will necessarily result.
The behaviour of the belf, in both of these cases, will be somewhat as follows
(d) The belt proceeding along the top of the Well, and in such a position that it
may touch the sides of the Well below the edges, practically forms a lid, and any
agitation of the liquid will be arrested by the underside of the belt.
We do not confine ourselves to the use of any particular position of the rollers, as it
is obvious that we may use any arrangement of these that will enable us, by means of
the belt, to prevent the spilling of the liquid. Accordingly, by the use of extra rollers
inside the Well, we may lead the belt in such a zigzag fashion, as that it shall keep up
a continual stirring of the liquid, and, at the same time, practically inclose the liquid
in so many little compartments that it shall be in no way likely to undulate or spill,
even if no lid be used.
On the other hand we may prefer to use a suitable lid or lids according to taste or
requirement.
(e) The Belt being made (preferably) of an absorbent material will do the work much
more efficiently in all cases, but especially upon smooth surfaces such as cement &c.
upon which India Rubber has been proved to be unsatisfactory.
(f) The Marker being provided with another wheel of any suitable shape or
dimensions, working in direct line with the beforementioned driving or marking wheel,
and at its other extreme end, will run upon two wheels only, and will in no way
require guiding to keep it in straight line: and, in order to suit the conditions herein-
before laid down the handle shall be hinged or similarly attached at a convenient point
on the machine, so that while it will retain the machine in the vertical position, it will be
flexible in the horizontal direction, and so allow the Marker to ride over inequalities
without vibration, or alteration in the position of the hand of the operator.
As a matter of course our belt is an endless one, and may be run upon wheels and
rollers in any combination provided that we can thereby cause it to fulfill the office of
a lid to the marking liquid.
Thus, we may double our roller gear at the top of the machine, and, leaving sufficient
space between the rollers for filling the Well, we can make the belt to run over two
large wheels instead of one, and so produce a machine that shall have the belt for a lid,
and, owing to the flexible or folding handle, shall be capable of working in either
direction.
We may attach fixed or automatic props which shall enable the operator to leave
the machine standing in a sufficiently upright position. Moreover, if found advisable,
we may groove our wheels and rollers so as not to wring out so much of the marking
liquid, from the belt, and we may add scrapers or other such devices as may prevent
any of the marking liquid from falling upon the ground where no mark is intended to
be made.
We propose to construct the machine in such parts, that the whole will come to
pieces or fit up by means of two bolts or screws, and we prefer to use glass for the
wheels and rollers, but we do not confine ourselves to any material; and, we may (if
expedient) construct our Marker as a casting (so far as it is possible) in which case we
should probably dispense with bolts and screws, as the only means of fixing the parts.

We JAMES MCHARDY Dollar North Britain Scientific Expert and ROBERT BRAND,
Hebron Bank Canaan Lane Edinburgh India Rubber Merchant do hereby declare the
nature of our invention for AN IMPROVED LAWN TENNIS MARKER and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :—
The well shall be a deep one instead of the shallow well of ordinary markers; and
being tapered longitudinally from convenient dimensions at the top, to the apex of a
triangle or to the are of a circle at the apex of a triangular figure, at the bottom, the
belt passing over a roller at the bottom of the said well, shall use up the marking liquid
to the last drop.
The well being made narrow at the top (or throughout its dimensions) the belt may
become, by the arrangement of rollers (hereinafter mentioned) in itself a kind of lid to
prevent the spilling of the liquid, or; a lid or lids may be used for this purpose
By placing a roller at one of the upper ends of the well, another at the bottom of the
well, a third at any convenient point near the upper edge of the well, and using a
large driving or marking wheel, the belt may be so arranged that in working the
machine with the large wheel foremost, the belt shall pass directly from the well over
the roller at or near the upper edge of the well, out over the roller at the end
(but not touching or interfering with this latter roller) thence to the large wheel and
the ground, without having had its more whitened surface disturbed, between the time
of its leaving the well and coming to its work.
By working the machine with the large wheel behind the opposite effect will be
produced.
The behaviour of the belt in both these cases will be somewhat as follows;
The belt proceeding along the top of the well and in such a position that it may
touch the sides of the well below the edges, practically forms a lid.
We do not confine ourselves to any particular position of the rollers, as it is obvious
that we may use any arrangement of these that will enable us by means of the belt to
prevent the spilling of the liquid.
The marker, being provided with another wheel of any suitable shape or dimensions
working in direct line with the beforementioned driving or marking wheel, and at its
other extreme end, will run upon two wheels only and will in no way require guiding
to keep it in straight line; and in order to suit the conditions, hereinbefore laid down,
the handle shall be hinged or similarly attached at a convenient point on the machine
so that while it will retain the machine in the vertical position it will be flexible in the
direction of the wheels.
We can also make the belt run over two large wheels instead of one and so produce a
machine that shall have the belt for a lid and, owing to the flexible or folding handle
shall be capable of working in either direction.
We may attach fixed or automatic props which shall enable the operator to leave the
machine standing in a sufficiently upright position.

marking liquid from the belt.
