Improved Method of Manufacturing Cloth Boards.
1, WILLIAM HERBERT MARCON, of 130-132 King Street, East, in the City of
Toronto, in the County of York, in the Province of Ontario, Canada, Manu-
facturer, 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 relates to an improved method of manufacturing cloth boards and
the object of the invention is to produce a much cheaper, thinner, lighter, stronger
and more perfect board than that commonly in use and such a board as will not need
to be covered in order to protect the fabric from injury and it consists essentially
in the method exhibited by the various steps hereinafter more particularly set
forth.
Figs. 1, 2, 3, 4, 5, and 6 exhibit the various steps of the method.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A are the logs of wood, which are cut any suitable length and placed in a
vat B (see Fig. 1) and boiled or steamed sufficiently soft when the bark may be
removed. A log A after undergoing the above treatment is placed in a veneering
machine as at C (see Fig. 2) and by revolving against a knife D the wood is sliced
off in a wavy length with the grain across as represented by a, such length being
of the required thickness. This wavy length of wood is then introduced into a
clipping machine (see Fig. 3), which provided with an adjustable stop E¹ and a
knife E by which the wood is cut cross ways into desired widths. The boards a¹
thus produced are preferably passed endwise through a series of pairs of
rollers F F (see Fig. 4) heated by steam and by this means the wavy or a series
of concavo-couvex forms in the board are taken out and the boards rendered flat,
and completely dried.
After being dried the boards are passed through a machine with cutters G
(see Fig. 5) so as to round off the edges of the boards, where upon the boards are
passed through a sand papering machine H (see Fig. 6) so as to finally finish it
and render its surface smooth and free from any knots, splinters or any inequalities
of surface, which could serve to injuriously effect the fabric when wound upon
the board.
Instead of the steam rollers shown in Fig. 4. other suitable means for
applying pressure to the boards and drying them may be employed, such as
Alat metal boxes or plates with heat applied to the same, and so arranged as to
exert a pressure upon the boards, so as to render them flat and completely dry
them.
When the boards are completed they may be kept under pressure in bundles
properly wired for convenience in handling.
It is my intention to make the board out of hard wood, so that it may take a
fine polish and be made lighter.
In a board produced by the method thus described there will be no necessity
for papering it as the wood undergoes a process of boiling which leaves no sap or
esinous matter in it which will injuriously effect or discolor the fabrics.
It may be also pointed out that the board may be produced very cheaply as
compared with other cloth boards and may be made any desired width required,
which on account of the scarcity of wide lumber it is difficult to do when made of
Prins e27

page_text: sawn lumber as the cost of wide lumber is very high. There is also no waste in
producing my board.
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. The method of producing cloth boards herein shown and described consisting
in first boiling or steaming the log out of which the boards are to be made and
passing such log through a suitable machine, so as to slice the wood from the
periphery of the log in a continuous wavy length of desired thickness then gauging
and cutting cross wise into strips of desired width the wavy length of wood and
finally subjecting each strip so separated from end to end to pressure and heat as
set forth.

gauging and cutting cross wise into strips of desired width the wavy length
of wood, then subjecting each strip so separated from end to end to pressure
and heat then applying suitable cutters to the edge of the board, so
round off the corners and finally sand papering the board as set forth.
