CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CUTTING OR RASPING DYE WOODS
Year: 1856

page_text: LETTERS PATENT to John Roscow, of Radcliff, in the County of Lancaster,
Drysalter, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR CUTTING OR RASPING DYE WOODS."
Sealed the 7th April 1857, and dated the 13th October 1856.
PROVISIONAL SPECIFICATION left by the said John Roscow at the
Office of the Commissioners of Patents, with his Petition, on the
13th October 1856.
I, JOHN Roscow, of Radcliffe, in the County of Lancaster, Drysalter, do
hereby declare the nature of my said Invention for "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR CUTTING OR RASPING DYE WOODS," to be as
follows:-
My Invention relates to the plate or instrument used for cutting, chipping,
or rasping dye woods, and consists in the novel construction and conformation
of. such cutting apparatus. The plate in which the cutters are set has its face.
or front divided into three parts or divisions in circles, the two outside parts
being left plain, and the part between these being contrived to hold any
quantity of cutters required,' arranged round and radiating from the centre of
such plate. This disc or plate is "bevilled" from the inner edge of the
cutting division to the periphery, in a similar manner to a "bevil wheel," and
has motion imparted to it in a direction from right to left of its centre, or vice

page_text: versa, the wood being supplied to the cutters at the side about the level of the
axis of the disc. If a rotatory motion is now given to the disc and cutters,
and the wood to be cut be supplied, it will be evident that the wood will be
cut, rasped, or chipped (according to the formation of the cutters) at the point
of supply, and the cuttings &c. will be carried down by the cutters until
they arrive at the point perpendicularly beneath the centre of the disc, upon
which the cuttings will fall from the cutters perpendicularly into a receptacle
provided for them by reason of the angle or bevil of the cutters and disc, and
thus prevent the cutters becoming filled or clogged up by the cuttings.
A second advantage gained by the use of this machinery is, that small pieces
of wood may be cut as quickly. and with as much facility as the larger logs,
which has hitherto been impracticable.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Roscow in the Great Seal Patent Office on the
13th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
Roscow, of Radcliffe, in the County of Lancaster, Drysalter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of the reign
of for Herself, Her heirs and successors, give and grant unto me, the said
John Roscow, Her especial license that I, the said John Roscow, my execu-
tors, administrators, and assigns, or such others as I, the said John Roscow,
my executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter daring the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR CUTTING OR RASPING DYE WOODS,"" upon the condition, amongst
others, that I, the said John Roscow, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Roscow, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
:-
My Invention relates to the plate or instrument used for cutting, chipping,
or rasping dye woods, and consists in the novel construction and conformation
of such cutting apparatus. The plate in which the cutters are set has its plate
or front divided into three parts or divisions in circles, the two outside parts
being left plain, and the part between these being contrived to hold any
quantity of cutters required, arranged round and radiating from the centre of
such plate. This disc or plate is bevilled from the inner edge of the cutting
division to the periphary, in a similar manner to a "bevil wheel," and has
motion imparted to it in a direction from right to left of its centre, or vice
versâ, the wood being supplied to the cutters at the side, about the level of the
axis of the disc. If a rotary motion is given to the disc and cutters, and the
wood to be cut be supplied, it will be evident that the wood will be cut, rasped,
or chipped (according to the formation of the cutters) at the point of supply,
and the cuttings will be carried down until they arrive at the point per-
pendicularly beneath the centre of the disc, upon which the cuttings will fall
from the cutters perpendicularly into a receptacle provided for them, by reason
of the angle or bevil of the cutters and disc, and thus prevent the cutters
becoming filled or clogged up by the cuttings. A further advantage obtained
by the use of this machinery is, that small pieces of wood may be cut as
quickly and with as much facility at the larger loss, which has hitherto been
impracticable. In order that the Invention may be better understood and
explained in detail, I have hereunto attached a Sheet of Drawings, made about
one quarter the real size, and having similar letters of reference marked upon
corresponding parts of the apparatus throughout all the Figures.
Fig. 1 is an elevational view of the disc or plate shewing the slots in which
the rasps, cutters, or saws are secured; in this view only three serrated cutting
edges are shewn for sample. Fig. 2 is a plan view of the feeding trough,
shewing the disc or plate in section,, illustrating more clearly the method of
securing the cuttings.
In Figs. 1 and 2, a, a, is the plate or disc, and b, b, the slots, in which are
fixed the cutters c, c, by means of the bolts c, c', and by which they may be
adjusted; and d is the shaft upon which the disc rotates; and e is the trough
for supplying the wood to the cutters, which is placed at a suitable angle (as
shewn) to allow for the bevilled surface of the disc. It will be readily under-
stood that when a rotary motion is given to the disc and cutters, that the wood
presented to such cutters will become cut, chipped, or rasped by the action of
the cutters thereupon, and also that by the cutters being placed in a position

page_text: so as, to radiate from, the centre of a disc, or continuous action of the cutters.
upon the wood will be effected instead of one, cutter following the other, as,
when placed longitudinally across, a cylinder. I would here remark that the
cutters employed may be of any suitable form, whether having serrated,
roughened, or sharpened cutting or rasping edges.
Having now. described the nature of my said Invention, together with."the
manner of carrying the same, into effect, I wish it to be distinctly understood,
that I claim, first, the novel application and use. of a disc or plate. having slots
for the reception of the cutters formed therein, in lines radiating from the
centre of such disc, and having also the whole or part of its face or front
surface containing the cutters bevilled or angled, so as when thus combined to
effect a more continuous and steady action of the cutters upon the wood, as
herein-before, described, set forth, and fully illustrated in the accompanying.
Drawings..
In witness whereof, I, the said John Roscow; have hereuntó set my. hand
and seal, this Ninth day of April, in the year of our Lord One
thousand eight hundred and fifty-seven.
