the County of York, Timber Merchants, for the Invention of "IM-
PROVEMENTS IN SAW FRAMES OR MACHINERY FOR CUTTING TILE, SLATE, AND
OTHER LATHS, BOARDS, DEALS, BATTENS, AND OTHER WOODS AND MATERIALS
USUALLY CUT BY SAWS."
ealed the 19th November 1872, and dated the 25th June 1872.
PROVISIONAL SPECIFICATION left by the said Charles Caselton and
Henry Toogood at the Office of the Commissioners of Patents
with their Petition, on the 25th June 1872.
We, CHARLES CASELTON, Foreman, and HENRY TOOGOOD, Partner in
the Firm of Brown, Toogood, and Company, of Hull, in the County of
York, Timber Merchants, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN SAW FRAMES OR MACHINERY FOR CUtting Tile,
SLATE, AND OTHER LATHS, BOARDS, DEALS, BATTENS, AND OTHER WOODS AND
MATERIALS USUALLY CUT BY SAWS," to be as follows :-
This Invention relates to improvements in machinery for sawing tile,
slate, and other laths, boards, deals, battens, and other woods and

page_text: materials usually cut by saws, and our Invention has for its object
improvements in the general arrangement, construction, and combination
of parts, particularly the method of mounting a series of rotary saws
The saws are set
upon a spindle so as to prevent them from buckling.
upon the spindle or axis at such distances apart as to cut the laths to a
any desired size, say from half an inch thick and upwards.
The saw spindle or axis is of suitable length for the number of saws
and purpose required. Upon the saw spindle we first place one of the
series of saws, then a packing faced up to the thickness required, a
malleable iron bar (which slides in a V slot on the saw table top) is then
fixed in position, coming flush so as to present a perfectly smooth surface
and fill up the space between the saws. This arrangement of alternate
saws and bars is repeated until the requisite number of saws are mounted
for the width of board to be cut.
In order to prevent the saws from buckling and running, we fix a
the
piece of leather rivetted with copper pins at each side of every bar,
leather being just thick enough to admit of the saws clearing, and if the
saws should run or buckle they then come in contact with the leather
The saws are
and copper pin which will do them little or no injury.
then packed upon the leather (which forms a good shoulder, by pre-
ference about a quarter of an inch wide) with soft yarn or other suitable
material. By this means all the saws can be packed and set true to the
greatest nicety.
The packing and leather does not come past the teeth of the saws, but
commences about a quarter of an inch past the root of the saw tooth and
continues up to the shoulder of thickness plate upon the spindle.
'
By the above arrangement. we can run the saws perfectly true and
smooth without the least chattering.
The machine is fitted with self-feed motion, and the speed, which is
taken from the saw spindle, is so reduced by straps working upon other
pullies as to run the board between the feed rollers at a speed of from
15 feet per minute up to 24 feet per minute.
By means of a lever the feed rollers can be lifted so as to stop the
cutting instantly. We also raise and lower the saw spindle by means of
a screw, so that should the saws stand too high above the table we can
then at once lower them to the thickness required for cutting, thereby

page_text: saving power. The machine can be made portable without being taken
to pieces, having all the gearing arranged and adapted upon one frame,
and can be fed and attended by any ordinary workman.
A guard fence is set true and square with the saw spindle and can be
adjusted for thickness of lath. A spring guard roller is also arranged in
front of the board to be cut in order to keep it up to its work and enable
it to run true.
The accompanying Drawing shows the method of mounting and
arranging the saws, steadying bars, and packing, as previously described,
in accordance with our Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Oharles Caselton and Henry Toogood in the Great
Seal Patent Office on the 24th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
CASELTON, Foreman, and HENRY TOOGOOD, Partner in the Firm of
Brown, Toogood, and Company, of Hull, in the County of York, Timber
Merchants, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Charles Caselton and Henry Toogood,
Her special license that we, the said Charles Caselton and Henry
Toogood, our executors, administrators, and assigns, or such others
we, the said Charles Caselton and Henry Toogood, our
cutors, 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 "Iμ-
PROVEMENTS IN SAW FRAMES OR MACHINERY POR CUTTING TILE, SLATE, AND OTHER
LATHS, BOARDS, DEALS, BATTENS, AND OTHER WOODS AND MATERIALS USUALLY CUT
BY SAWS," upon the condition (amongst others) that we, the said Charles
Caselton and Henry Toogood, our executors or administrators, by an in-
strument in writing under our or their, or one of their hands and seals,

page_text: or under the hand and seal of one of us or them, 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 we, the said Charles Caselton and Henry
Toogood, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to
say :-
This Invention relates to improvements in machinery for sawing tile,
slate, and other laths, boards, deals, battens, and other woods and
materials usually cut by saws, and our Invention has for its object im-
provements in the general arrangement, construction, and combination
of parts, particularly the method of mounting a series of rotary saws
upon a spindle so as to prevent them from buckling. The saws are set
upon the spindle or axis at such distances apart as to cut the laths to
any desired size, say from half an inch thick and upwards.
And in order that our Invention may be clearly understood and
readily carried into practice, we will proceed to describe the same,
reference being had to the Drawings hereunto annexed and to the figures
and letters marked thereon.

page_text: in a V slot on the saw table top d) is then fixed in position, coming flush
with the upper surface of the table so as to present a perfectly smoothi
surface, and thus fill or nearly fill up the space between the saws.
This
arrangement of alternate saws band bars c is repeated until the requisite
3 number of saws are mounted for the width of board to be cut up into
laths or other pieces.
In order to prevent the saws 6 from buckling, "running," or twisting,
we fix a piece of leather c³, rivetted with copper pins, at each side of
every bar c, the leather being just thick enough to admit of the saws
clearing, and if the saws should run, twist, or buckle, they then come in
contact with the leather and copper pins, which will do them little or no
injury. The saws are then packed upon the leather (which forms a good
shoulder, by preference about a quarter of an inch wide) with soft yarn
or other suitable material c². By this means all the saws can be packed
and set truc to the greatest nicety.
The packing and leather does not come beyond the teeth of the saws
but commences about a quarter of an inch beyond the root of the
saw tooth and continues up to the shoulder of thickness plate upon the
spindle, as clearly shown at Figures 4, 5, and 6, of the Drawings.
By the above arrangement the saws can be driven perfectly true and
smooth without the least chattering,
The machine is fitted with self-acting feed and delivery motion
rollers d, d, which are driven by a band 1 from the saw spindle, and the
speed is so reduced by the endless driving straps 1, 2, 3, 4, and 5,
(running upon suitable pullics and axes, as clearly shown in the Draw-
ings) as to carry the board between the feed rollers at a speed of from
15 feet per minute up to 24 feet per minute, or at any suitable speed as
may be desired. c, e, are rollers mounted upon weighted levers to keep
the board in position whilst being cut.
The feed rollers d, d, can be stopped by means of a lever to throw
the main strap from saw spindle upon a loose pulley so as to stop the
cutting instantly when required, thus enabling the saws to continue
running and thus clear themselves, and also get cool should they become
heated.
The saw spindle can be raised and lowered if required by means of
screws a¹, a¹, actuated by the shaft a and bevil wheels a³, a³, as shown

page_text: in Figure 3, so that should the saws stand too high above the table, they
can then be lowered to the thickness required for cutting, thereby saving
power.
A guard fence f is set truc and square with the saw spindle and can
be adjusted for thickness of lath.
A spring guard roller g is also
arranged in front of the board / to be cut, in order to keep it up to its
work, and thus enable it to run true.
The machine can be made portable without being taken to pieces,
having all the gearing arranged and adapted upon one frame, and can be
fed and attended by any ordinary workman. The framing may if
preferred be made of iron.
Having thus described the nature of our Invention, and the manner of
performing or carrying the same into practice, we would have it under-
stood that we do not confine ourselves to the exact details herein-before
described, but what we claim is,―
First. The improved method of mounting a series of saws & upon a
spindle a in combination with fixed steadying bars c and packing to
prevent the saws from buckling, "running," or twisting, arranged so as
to act substantially in the manner herein-before described, and shown in
the Drawings hereunto annexed.
Secondly. We claim the improved arrangement and combination of
saw frames or machinery for cutting tile, slate, and other laths, boards,
deals, battens, and other woods and materials usually cut by saws,
substantially in the manner herein described, and shewn in the accom-
panying Drawings.
In witness whereof, wc, the said Charles Caselton and Henry
Toogood, have hereunto set our hands and seals, this Twenty-
first day of December, in the year of our Lord One thousand eight
