Year: 1871

page_text: LETTERS PATENT to William Snowdon, of Rochdale, in the County
of Lancaster, for the Invention of "IMPROVED CUTTER BLOCKS FOR
HOLDING CUTTERS OR CHISELS USED IN WOOD CUTTING AND ALL MOULDING
MACHINES."
Scaled the 19th September 1871, and dated the 20th March 1871.
PROVISIONAL SPÉCIFICATION left by the said William Snowdon at
the Office of the Commissioners of Patents, with his Petition, on
the 20th March 1871.
I, WILLIAM SNOWDON, of Rochdale, in the County of Lancaster,
5 do hereby declare the nature of the said Invention for "IMPROVED CUTTER
BLOCKS FOR HOLDING CUTTERS OR CHISELS USED IN WOOD CUTTING AND ALL
MOULDING MACHINES" (to be as follows):
This Invention relates to cutters having their cutting edges of various
shapes according to the forms of the mouldings or other work required,
and consists in making the cutter blocks in such a manner that cutters
made of bar. steel can be so held that the wood or material to be moulded

page_text: or worked can be pushed when required close up to the spindle to which
the cutter block is fixed.
In one arrangement the cutter block is made of three or more pieces,
the central piece being fixed to the cutter spindle of the machine, and
between these pieces the cutters are held when the pieces are screwed or 5
bolted together.
In another arrangement I form the cutter block of one piece tapering
downwards, and to the sides or periphery of the block the cutters are
fixed by screws or bolts and plates.
And in another arrangement I form the cutter block with a number 1
of arms projecting from a central boss fixed to the cutter spindle, and
to these arms the cutters are screwed or bolted at any required angle,
and in all these arrangements the cutters can be close to or at any
required distance from the circumference of the cutter spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Snowdon in the Great Seal Patent Office
on the 20th September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SNOWDON, of Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of March, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Snowdon, Her special license that I,
the said William Snowdon, my executors, administrators, and assigns, or
such others as I, the said William Snowdon, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during 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 "IMPROVED CUTTER BLOCKS FOR HOLDING CUTTERS OR
CHISELS USED IN WOOD CUTTING AND ALL MOULDING MACHINES," upon the con-
dition, amongst others, that I, the said William Snowdon, by an instru-
ment in writing under my hand and seal, should particularly describe and

page_text: 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 William Snowdon, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the figures on the
accompanying Sheet of Drawings, and to the letters of referenco marked
thereon, that is to say :-
This Invention relates to cutters having their cutting edges of various
shapes according to the forms of the mouldings or other work required,
and consists in making the cutter blocks in such a manner that cutters
made of bar steel can be so held that the wood or material to be moulded
or worked can be pushed when required close up to the spindle to which
the cutter block is fixed.
In one arrangement the cutter block is made of three or more pieces
of metal, the central piece being fixed to the cutter spindle of the
machine, and between these pieces the cutters are held when the picces
are screwed or bolted together.
In another arrangement I form the cutter block of one piece tapering
downwards, and to the sides or periphery of the block the cutters are
fixed. by screws and plates.
And in another arrangement I form the cutter block with a number
of arms projecting from a central boss fixed to the cutter spindle, and
to these arms the cutters are screwed or bolted at any required angle,
and in all these arrangements the cutters can be close to or at any
required distance from the cutter spindle.
On the accompanying Sheet of Drawings Figs. 1 and 2 are side and
end views, Fig. 3 a transverse section, and Fig. 4 a view of the under
side of the first arrangement of my improved cutter blocks; Figs. 5, 6,
and 7 are views of the second, and Figs. 9 and 10 are side and top views
of the third.
The cutter block shewn in Figs. 1, 2, 3, and 4 is formed of five plates
or pieces a, b, c, d, e, and in spaces between are placed the cutters ƒ, I,
and in the central plate or piece c there is a hole into which is placed
and fastened the spindle h. The two cutters f are first held between

page_text: the plates b, c, d, by the screws ½ in. order that they can be adjusted as
required, and then the outer cutters are placed between the plates a, b,
and d, e, and slightly held for adjustment by the screws 7, and when
the adjustments are complete the screws are tightly screwed up and
the cutters and plates are held firmly together.
The cutter block is shewn in Figs. 5, 6, and 7 consists of a central
piece of metal tapering downwards to the spindle o, to which it is fixed,
and the cutters are held firmly in any required position by the
'screws q and plates r, the cutting edges of the cutters being near the
spindle in Fig. 5 and at a distance from it in Figs. 6 and 7.
In Figs. 9 and 10 the cutter block consists of arms ț projecting from
the central boss u having a hole for enabling it to be fixed to the
spindle v, and the cutters w are held firmly to the arms t by the screws
and plates y, and it will be seen that in all the arrangements cutters
made of bar steel can be used close to the spindle or in any other
required position.
Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to
be understood that I claim the improved cutter blocks for holding
cutters or chisels used in wood cutting and all moulding machines, as
herein described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said William Snowdon, have hereunto set
my hand and seal, this Nineteenth day of September, in the year
of our Lord One thousand eight hundred and seventy-one.
'Signed, sealed, and delivered by the
within-named William Snowdon in
the presence of
