A Dot Marker for Teaching Sewing.
I, ARTHUR Edward Wright of 247 Bute Street Cardiff, in the County of
Glamorgan in South Wales, Engineer, do hereby declare the nature of this invention
to be as follows:-
.
My invention refers to a dot marker for teaching sewing; by means of which
dots are impressed upon pieces of calico in such directions & at such distances
apart as to indicate the length & kind of stitch which is required to be made, and
consists of a small bracket of wood, metal, or other suitable substance, one end of
which is forked in such a manner that a small wheel of rubber, wood, metal or
other suitable material may be made to freely revolve upon an axle between the
two arms of the fork. From the circumference of the wheel extend small pointed
projections at certain distances apart, so that when inked & the marker passed over
the calico, or other material, to be marked, the wheel will turn upon its axlė
between the forked ends of the bracket, and each projection will mark a dot upon
the calico. Various wheels are made having the projections so arranged upon
their circumference as to mark either single, double, or treble rows of dots, & with
either regular or irregular distances between the dots in each row, & any number
of dots to the linear inch as may be required, a separate wheel being required for
each system of dots.
Behind the wheel & also between the forks of the bracket is an inking pad, in
the form of a roller made of felt or of wood, metal or other substance covered with
felt, or other absorbing material, to which any coloured inking fluid may be
applied.
The inking roller turns freely upon an axle, & has its circumference in contact
with the points of the projections from the marking wheel, in such a manner that
when the marking wheel revolves it causes the inking roller to turn, by which
means the projections are constantly supplied with the ink, or marking fluid.
The bracket, carrying between its forked ends the marking wheel & inking
roller, is fixed in a turned wood handle for convenience of using in the hand.
A flat ruler of wood or metal may be used as a guide to enable the row or rows
of dots to be marked in a straight line.

1, ARTHUR EDWARD WRIGHT of 247 Bute Street Cardiff, in the County of
Glamorgan, Engineer 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 :—
My invention has for its object a dot marker for teaching sewing, by the use of

page_text: which calico or other fabrics may have small dots imprinted upon them in such
forms as to serve as a guide for teaching needlework in schools and other such
institutions.
My appliance consists of a small bracket, preferably of metal, but which may be
made of any other suitable material, which is fixed by one end into a handle of
wood or other substance and which has its other end extended to form two shafts
(Fig. I^) between which are carried a marking wheel and inking roller. The
marking wheel is preferably made in brass but may be of any other metal or
material which may be suitable, and is constructed of two or more round discs
placed face to face, each disc having, short pointed projections extending from its
circumference (Fig. II). The discs are fastened together by solder or other
cement in such positions that the points of the projections of one disc alternate
with those of the other; or may be placed so that the projections of either disc
come opposite those of the other, or in any other position which may be desired.
Any number of such discs may be in like manner fitted together. Any desired
distance between the discs is obtained by inserting between them washers of
suitable thicknesses.
The marking wheel thus constructed has a hole drilled through its centre for the
insertion of a small screw by which it is fixed between the arms of the bracket, and
which serves as an axle upon which it rotates.
When the points of the projections of the marking wheel thus mounted in the
bracket, before described, are moistened with an inking fluid & wheeled over the
calico or other fabric to be marked, each projection will imprint upon it a dot,
the projections being so arranged, as before set forth, that two or more parallel
rows of dots are marked, which may have any specified distances between them;
and the dots in each row may have either regular or irregular spaces between
them, and there may be any number of dots to the linear inch which may be
desired. The distance between the rows of dots is obtained as before set forth by
inserting a washer of requisite thickness between the discs of which the marking
wheel is constructed the distance apart of the dots in either row being determined
by the spaces between the projections which extend from the circumference of the
discs, a separate marking wheel being required for each system of dots. The
marking wheel is supplied with ink by a roller of rubber or other suitable substance,
which rotates on an axle between the shafts of the bracket, and behind the marking
wheel (Fig. IVA) in such a manner that its circumference is in contact with the
points of the projections of the marking wheel, and is turned on its axle when the
marking wheel rotates.
The inking fluid is contained in a small wad of absorbent material-as sponge or
cotton which is fixed by a cement between the shafts of the bracket, and is in
contact with the face of the roller, and to which any coloured marking fluid may
be supplied (Fig. IV³).
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. A marking wheel exactly as described, from the circumference of which
extend two or more rows of projections arranged in any and various forms and
distances apart.
2. A rotary inking pad to convey an inking fluid from a reservoir to the marking
wheel.
3. A bracket, in which is fixed the marking wheel, inking pad, and ink
reservoir, exactly as described forming together a self inking dot marker.
