Improvements in Wood-working Machinery.
We, SAMUEL INGHAM, WILLIAM ILLINGWORTH, and HENRY OXLEY
INGHAM, Members of the Firm of Illingworth, Ingham & Co., of 76 Wellington
Street, Leeds, in the County of York, Timber Importers, and JOSEPH WILLIAM
HAYWOOD, of 82 Buriey Lodge Road, Leeds, aforesaid, Saw Mill Manager, do
hereby declare the nature of this invention to be as follows:-
The invention has reference to the class of planing and moulding machinery in
which all surfaces (top, bottom, and sides) of the scantling, as it passes through
such machinery, are operated on.
The object of the invention is to produce an effect on the strip of wood passed
through the machine which may be described as equivalent to operating on (at
least) eight sides at one journey.
In this way mouldings, matched boardings, facia moulds, and the like, when
required in large quantities, may be produced as multiple mouldings, which are
completed, and sub-divided, in one journey through the machine.
We accomplish our object as follows:-Taking for an example a moulding which
lends itself to be produced in a double (back to back) form; we arrange: top and
bottom cutters to produce the required mouldings, whilst the two side cutters are
engaged with the work requisite on the sides; all this may be done in a machine
arranged more or less as usual. After the scantling has passed these cutters it is
carefully guided and made to impinge on a high speed circular cutter or saw, so
mounted, on a vertical axis, that it divides the scantling in two pieces, the top
forming one moulding, and the bottom piece (which is upside down) the other.
The nearly finished work, as it approaches the dividing cutter or saw, is as much
deeper as the width of that cutting edge demands, so that the mouldings are
reduced to the depth required.
We so mount our dividing cutters or saws, that they may be raised, lowered, or
traversed into any desired position to suit different scantlings.
Further, there may be one or more dividing cutters or saws, and of these, one
or more may be mounted vertically (on horizontal axes) to further sub-divide the
work already divided; thus by taking a scantling, and arranging the necessary
forming cutters, of double width, four complete mouldings may be produced in one
passage through the machine.
In specifying the first mentioned dividing cutters or saws as working horizontally,
this must be accepted as a relative term, as they (or the others) may sometimes be
angled to suit special requirements.
From what appears here it is evident that the invention is applicable to
numerous requirements where mouldings, and the like, lend themselves to multiple
production, and sub-division, during a single journey through the machine.
Dated this 20th day of February 1895.

page_text: We, SAMUEL INGHAM, WILLIAM ILLINGWORTH, and HENRY OXLEY
INGHAM, Members of the Firm of Illingworth, Ingham & Co., of 76 Wellington
Street, Leeds, in the County of York, Timber Importers, and JOSEPH WILLIAM
HAYWOOD, of 82 Burley Lodge Road, Leeds, aforesaid, Saw Mill Manager, 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 :-
The invention has reference to the class of planing and moulding machinery in
which all surfaces (top, bottom, and sides) of the scantling, as it passes through
such machinery, are operated on.
The object of the invention is to produce an effect on the strip of wood passed
through the machine which may be described as equivalent to operating on (at
least) eight sides at one journey.
In this way mouldings, matched boardings, facia moulds, and the like, when
required in large quantities, may be produced as multiple mouldings, which are
completed, and sub-divided in one journey through the machine.
In order to describe our meaning we have annexed two sheets of drawings on
which
Fig. 1 is a side elevation, and Fig. 2 a plan, of our improvements.together with
such parts of a moulding machine as are necessary to a full understanding of the
invention.
Figs. 3, 4 and 5 are diagrammatic cross-sections of work done.
The other figs. we refer to as we proceed. The same letters refer to the same
parts in all the figures.
We accomplish our object as follows:-Taking for an example a moulding
which lends itself to be produced in a double (back to back) form; we arrange
top and bottom cutters D and A to produce the required mouldings, above and
below, whilst the two side cutters, B and C, are engaged with the work (moulding
or otherwise) requisite on the sides; all this may be done in a machine. having
four cutter blocks arranged more or less as usual, although the details shown are
based on
an arrangement for which Letters Patent were granted in 1893,
No. 10,916. After the scantling has passed these cutters it is carefully guided by
a fence or fences at e¹, and made to impinge on a high speed circular cutter or
saw E, so mounted, on a vertical axis, E, that it divides the scantling in two
pieces, the top forming one moulding, and the bottom piece (which is upside down)
the other. The nearly 'finished work, as it approaches the dividing cutter or saw,
is as much deeper as the width of that cutting edge demands, so that the mouldings
are reduced to the depth required, as shown in Fig. 3, where X, .X, iis the
saw cut.
We so mount our dividing cutters or saws, that they may be raised, lowered, or
traversed into any desired position to suit different scantlings. In Fig. 11, E2 is a
slide allowing the saw to be raised or lowered, and E³ is a cross slide for moving
it sideways.
Further, there may be one or more dividing cutters or saws, and of these, one
or more, see F, may be mounted vertically (on horizontal axes) to either divide
the work vertically as in Fig. 4, or to further sub-divide the work already divided,
as in Fig. 5 (X, X, again representing the saw cuts), thus by taking a scantling,
and arranging the necessary forming cutters, of double width, four complete
mouldings may be produced in one passage through the machine.
The vertical saw F is mounted on the spindle F¹ so that it may be raised and
lowered by a vertical slide F2 and travelled across by the slide F³. Its driving

page_text: pulley should be taken to that side of the machine where there isimost; room for
its driving belt (or driving rope).
In specifying the first mentioned dividing cutters or saws as working horizontally,.
this must be accepted as a relative term, as they (or the others) may sometimes be
angled to suit special requirements; suitable swivelling provision being added to
meet these movements when required, such as at E and F*.
From what appears here it is evident that the inventionis applicable to numerous
requirements where mouldings, and the like, lend themselves to multiple production,
and sub-division, during a single journey through the machine.
When quadruple sections, such as Fig. 5, are being worked, the scantling, after
being divided horizontally by the saw E, travels forward as two members. The
bottom one continues to move forward say on the bed of the machine, and is
suitably guided so as to impinge truly on the saw F, by side guides at fl,,see
Fig. 7, which is a cross section of parts of the apparatus immediately over the
saw spindle F. As the top member moves forward immediate advantage is taken
of the gap, left by the saw E, for introducing the somewhat sharpened uose of the
separating table 12. Over this separating or false table the top member is caused
to travel in such a way as to impinge truly on the saw F by side guides at ƒ³-
which are practically similar to those at f¹ below. Both the upper and lower side-
guides, or fences, are arranged to stand openmouthed at 4 to receive any incoming
member that may be out of line. The lower guides support the false table, whilst
the upper ones are bolted thereto with a view of stiffening and holding all securely.
The false table, which may gradually increase in rearward thickness (in order to
relieve the front saw E from side friction; for the same reason the bed of.the
lower table may be arranged to fall away somewhat to the rear), is pierced by
the saw, and cuts the upper member on the false table as truly as it does the lower
one on the real table.
The top member is pressed down by the block f which is also pierced for the
saw F, the sides of the pressure block at f being guided by a raised portion of the
guide plates or fences f³ to secure accuracy. The pressure block, which has its
fulcra at d', is reproduced in plan in Fig. 6 for explanatory purposes, and may be
weighted as shown in dotted lines at 7.
A vertical separating blade (not shown) may be fixed at 18 at the rear of the
saw F, to give it the same relief that the saw E gets from the separating table f².
Such a blade is beneficial behind either of the saws when used. singly.
The modus operandi is as follows:-The scantlings are fed to the machine one.
behind another, as usual, and are pushed forward by the feed rollers G. (We would
here observe that as a great amount of work is thrown on the feed rollers the
pressure of all fences, guide blocks, etc., must be kept as light as possible.) After
this they are moulded by the bottom cutter A which must have a pressure block a¹
above it. In some cases a simple arrangement of hinged block to swing back out
of the way (for prompt access to the moulding cutters below) preferable to any
other. The next moulding knives met with are those on the side cutter heads;
these heads may be arranged in the same line (on the same cross slide below) with
suitable fences; or the special arrangement shown may be resorted to, as described
in our Patent herein before mentioned; here b¹ is a dead weight adjustable fence (a
side view of its lever being shown in Fig. 2A) and c¹ is a fixed fence meeting our
specially arranged cutter head and pressure block at C. A downward pressure
block is also arranged at c².
The next cutter head met is the top one at D, here both in front and behind,.
at d and d², are thrust blocks (that shown on the drawing at d¹ being patented
under No. 8552 of 1885). The block d² may be actuated by having its fulcrum
keyed to a shaft which is weighted at d. The fence or fences at el are now passed
and a pressure block e² keeps the scantling down to the nose of the saw E. This
block must be arranged with as little pressure on the saw as possible, but at the
same time it must keep down the end of the scantling last sawn and so keep up.
the continuity of the forward thrust from the feed rollers. After passing the saw E,.

page_text: "
the separating table and the guides and 3 and pressure blocks f³ lead the
divided members past the saw F, afterwards, as before mentioned, another separating
blade at may be arranged to relieve the saw F from side friction.
In most cases it will be necessary to carry away the dust from the saw E by an
exhausting air tube in order to keep all in free working order.
Where the saw F is used alone for double work, (Fig. 4) the arrangements are the
same excepting that there is no need for the separating or false table...
The face of the table of the machine from the bottom cutter A to, or near to, the
delivery end, should be.. arranged to take different forms of supporting paths,
especially where the bottom moulding has no average flats such as would otherwise
travel on the top face of the bed; in other words, when the bottom mouldings
require them, corresponding, supporting faces must be prepared for bearing up the
work as it passes through the machine, and under the saw or saws especially. All
movable fences are made adjustable by slots or the like.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvements in wood-moulding machinery substantially as described
herein and shown on the drawings, by which adjustments and operations may be made
on eight or more faces, and all work on the scantling finished at one passage through
such machine.
{
2. In a wood-moulding machine the combination of cutters A, B, C and D, with
their guides, fences, and pressure blocks (these latter being arranged preferably as
shown) working in conjunction with an horizontal saw or cutter E, suitably mounted
for adjustments and provided with guides, fences, pressure block, and separating blade,
for producing work diagrammatically shown in Fig. 3 at one passage, substantially
as described and shown.
3. In a wood-moulding machine the combination of cutters A, B, C and D,
preferably with guides and pressure. blocks as shown, working in conjunction
with a vertical saw or cutter F suitably mounted for adjustments, and provided
with guides, fences, pressure block, and separating blade, producing work
diagrammatically shown in Fig. 4 at one passage, substantially as described and
shown.
4. In a wood-moulding machine the combination of cutters A, B, C, D, with
adjustable saws or cutters E and F with their surroundings, producing quadruply
worked sections, such as that diagrammatically shown in Fig. 5, substantially as
described and shown.
