Improvements in Wood-working Machinery for Planing, Moulding,
and the like.
We, WILLIAM ILLINGWORTH, of 76 Wellington Street, of the Firm of
Illingworth, Ingham & Co., Timber Importers, of Leeds, in the County of York,
and JOSEPH WILLIAM HAYWOOD, of 82 Burley Lodge Road, Leeds aforesaid,
Saw Mill Manager, do hereby declare the nature of this invention to be as
follows:-
It refers
(1.) In the first place, to a mode of regulating the weight on the feed-rollers, to
any degree of nicety, by mechanism which may be promptly operated and altered.
whilst running; the object in view being to save the time now occupied by the
present mode of weighting. The present mode of weighting, by hand, leads to the
bad practice of keeping a maximum weight on the rollers, whereby light sections
of material are often unduly crushed in being passed through the machine.
(2.) In the second place, to a mode of regulating the speed of the feed-rollers, by
mechanisin which may be altered whilst running; with a view to allow the attendant
to slow down the feed, temporarily, whilst the cutters are passing over a hard or
otherwise bad place, and afterwards to promptly put the speed up again.
(3.) In the third place, to a mode of mounting the bottom cutter-head, so as to allow
it to be used on the square when working mouldings, or on the slant when a
"shear cut is desired for planing, etc.
22
(4.). In the fourth place, to a mode of arranging the side-cutters and their fences,.
etc., so as to give greater rigidity to the material operated on; a self-adjusting
dead-weight fence forming a portion of the scheme.
We carry out our invention thus :-(referring to the foregoing heads),
;
Firstly from the feed-rollers, rods are extended down to a lower platform which
is raised and depressed by a bell-crank-lever, and screw, as usual. The shaft of
the above mentioned bell-crank-lever has a long cross lever affixed to it (in a
position approximately horizontal) on which a sliding weight may be travelled by
a screw. When this overhangs on the platform side its weight is added to that of
the platform, and an increased weight is thrown on the rollers; but when moved
towards the other end a gradual decrease of weight results.
;
Secondly a friction wheel is so mounted, with its edge working against the flat
front of a plate wheel, that different speeds are given off according to the different
positions of the said wheels one to another. Screw-worked mechanism is used for
moving the first mentioned wheel to and from the axis of the plate wheel.
Thirdly by mounting this cutter-head and its bearings on an independent plate
(say in a horizontal plane), pivoted at one end, and secured at the other by bolts,
for the reception of which quadrant slots are provided in the said plate. A special
arrangement of belting is provided to meet the slanted positions of the drum
mounted on the cutter-head. In addition to this a dead-weight pressure-block, with
a lead-lined face, is mounted above the cutter-head, in order to deaden vibrations.
Fourthly by the following arrangement; exactly opposite the first side-cutter-
head is mounted the self-adjusting dead-weight fence before mentioned, whilst the :
second side-cutter-head has a fixed dead fence opposing it. Both these fences are
faced with lead for deadening vibrations. The self-adjusting fence is so arranged
that its face is moved in and out by a screwed shaft which is used for setting it to
the various widths of material, whilst the dead weights act on this same screwed
shaft, and thereby allow it to adjust itself to the minor variations required when
:

page_text: work is in progress. The second side-cutter-head is fitted with a pressure-block
such as that described in Patent No. 8552 of 1885. The top cutter-head is arranged
at the end of the machine, and this also has its pressure-block arranged in the
manner set out in the Patent last enumerated.

Improvements in Wood-working Machinery for Planing, Moulding,
and the like.
We, WILLIAM ILLINGWORTH, of 76 Wellington Street, of the Firm of
Illingworth, Ingham, & Co., Timber Importers, of Leeds, in the County of York,
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:-
This invention refers in the first place to a mode of regulating the weight on the
feed-rollers, to any degree of nicety, by mechanism which may be promptly
operated and altered whilst running; the object in view being to save the time now
occupied by the present mode of weighting. The present mode of weighting, by
hand, leads to the bad practice of keeping a maximum weight on the rollers
whereby light sections of material are often unduly crushed in being passed
through the machine.
$
(2.) In the second place to a mode of regulating the speed of the feed-rollers by
mechanism which may be altered whilst running; with a view to allow the
attendant to slow down the feed temporarily whilst the cutters are passing over a
hard or otherwise bad place, and afterwards to promptly put the speed up again.
(3.) In the third place, to a mode of mounting the bottom cutterhead, so as to allow
it to be used on the square when working mouldings, or on the slant when a
"shear" cut is desired for planing, etc.
(4.) In the fourth place, to a mode of arranging the side-cutters and their fences,
etc., so as to give greater rigidity to the material operated on; a self-adjusting
dead-weight fence forming a portion of the scheme.
We carry out our invention as follows:-Referring to the foregoing heads; and
also to the three sheets of drawings; Fig. 1 is a side elevation, and Fig. 2 is a plan
of the machine (slightly curtailed for want of space on the left hand margin, but
omitting nothing of importance). Fig. 3 is an end elevation; Fig. 4 a transverse
section on the line W, X, in Fig. 2; and Fig. 5 a longitudinal section on the
line Y, Z, in Fig. 2, through a portion of the "feed" gear. On these drawings the
pitch lines of all spur wheels are drawn by alternate short lines and dots, in front
view; and in side view diagonal lines connect their extremities. Arrows denote
direction of movement.
Firstly from the arms of the top feed rollers F³ and G³ (whose gearing is
described below) rods J extend down to a lower platform which is raised and
depressed by a bell crank lever J, J', and screw J* as usual. The shaft J of this
bell crank lever has a long cross lever K affixed and keyed to it in a position
approximately horizontal, on which a sliding weight K' is travelled backwards and
forwards by a screw K2 engaging in a uut K³. When this weight overhangs ou the
platform side, its weight is added to that of the platform, and an increased weight
is thrown on the feed rollers; but when moved towards the other end (that is,
towards the right hand position shown in the drawings) a gradual decrease of weight
on the feed rollers results.

page_text: Secondly; a friction wheel A. is so mounted with its edge working against the
flat front of a plate wheel B that different speeds are given off according to the
different positions of the said wheels one to another. As the mode of regulating
the weight on the top feed rollers is partly carried out by the manner of driving
them, it should be noted that the gear is so arranged that the driving force tends
to keep them to their work, and not to lift one off as it usually does. The plate
wheel B, mounted on the shaft B', is driven by a belt, inside the framing, running
over the pulley B'. This shaft is thrust against the friction wheel A whenever the
weighted lever B³, which is mounted on a steeply-pitched screw B, is brought over
into action. A stopping and starting arrangement is thus handy for the attendant's
A, on its shaft A, on which is also mounted a bevelled pinion A², gears with
the lower shaft A³ through the bevelled wheel A', whilst a pinion A³ gears into an
overhead wheel C on the upper shaft C. On this same shaft a pinion, C³, which
is centrally situated, gears into the two wheels D and E mounted on the shafts D'
and E' carrying the lower feed rollers D2 and E2. On these latter shafts are also
mounted, inside the frames the wheels D and E³, gearing into idle wheels D
and E, and so forward to F, and G, mounted on the fulcrum shafts F1 and G¹.
These in their turn gear into F2 and G2 mounted on the shafts of the top feed
rollers F3 and G³. These wheels cause the rollers to turn in the requisite direction
and in so doing the driving pressure tends to keep them down to their work, as
use.
before mentioned.
.
The friction wheel A has a recess and collar A into which studs H H, mounted
on a bar H', are introduced; the opposite end of this bar is fitted with a toothed
rack, H2, in which a small wheel H³, mounted on a shaft. H', gears; on this
shaft His further mounted a worm-wheel H', into which a worm mounted on the
end of a revolving rod is fitted; the worm and rod, which latter is brought up to
a handy height for the attendant, are not shown. By these means the attendant
has only to revolve the worm-rod, in the required direction to cause the friction
wheel A to move into any desired position between the axis and the periphery of
the plate wheel B, and thus the speed of the feed rollers is proportionally
regulated, slower or faster.
"
Thirdly; we mount the bottom cutter head L and its bearings, etc., on an
independent plate L', in a horizontal plane, (for position &c., see Fig. 1) and we
pivot the driving pulley end of the said plate on pin at L2, and provide a..
quadrant slot with the necessary fixing bolt at the other end L³, in such a way
that the whole may be twisted to an angle when a "shear cut is wanted. The
plate L is shown in a slanting position in Fig. 2, which see. As this slant throws
the driving pulley L, mounted on the cutter head, out of square, the driving belt
is led round two pulleys L' and L, which are shown as to their position in Figs. I
and 2. A dead-weight pressure block M with a lead-lined face M' is mounted over
the cutter head, as shown in Fig. 1, to deaden vibrations.
Fourthly; opposite the first side-cutter-head N we mount the self-adjusting dead-
weight fence before mentioned (the general arrangement of which is shown in the
section Fig. 4, and in plan in Fig. 2) whilst the second side-cutter-head O, has a
fixed dead fence O' opposing it. The self adjusting fence is so arranged that its
face N¹ is moved in and out by a screwed shaft or rod N2 which passes through
the screwed nut N³ attached to the body of N'. The dead weight N', acting
through a bell crank lever whose fulcrum is at No, presses continuously against a
collar N on the screwed rod and so keeps the fence to its work, whilst minor
inequalities in working cause it to yield. The fence is set in or out by revolving
the screwed rod for which purpose a squared end is left at N'. The body of the
feuce works in guides N8 as shown in Fig. 2. Both these fences N' and O' are
faced with lead at N° and O2 for deadening vibrations.
The second cutter head O is fitted with a pressure-block such as that described
in Patent No. 8552 of 1885, and made as shown at 03 Fig. 2 (that is, concentrically
hinged on the spindle O) a weight hung on a cord over the pulley N keeping it
against its work. The revolving top cutter head at P Fig. 1, is arranged at the

page_text: end of the machine as shown, and this also has its pressure block (not shown)
concentrically hinged on the spindle centre as under the Patent last enumerated.
Q is an ordinary dead weight fence desirable for holding down the work passing
between the cutter heads.
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 mode of regulating the pressure on the feed rollers, by a weight K¹
movable along an arm K, after the manner described and shown, with the object
and for the purpose set forth.
2. The mode of gearing feed rollers through wheels arranged as at F & F2
and G & G (F and G being mounted on the fulcrum shafts) substantially as
described and shown, with the object and for the purpose set forth.
3. The combination of the mechanism referred to in Claims 1 and 2, with the
object and for the purpose set forth.
4. The mode of varying the speed of the feed rollers by means of a friction
wheel A and a plate wheel B, together with the gear for altering their relative
positions, substantially as described and shown, with the object and for the purpose
set forth.
5. The mode of throwing the plate wheel B in and out of gear with the friction
wheel A, by means of a pressure screw B', substantially as described and shown,
with the object and for the purpose set forth.
6. The combination of the mechanism referred to in Claims 4 and 5, with the
object and for the purpose set forth.
7. The mode of mounting the bottom cutter-head on a horizontal bed plate
pivotting at the end near the driving pulley, together with the arrangement of
pullies for leading the belt off and on, substantially as described and shown, with
the object and for the purpose set forth.
8. The arrangement of a dead-weight fence adjustable by hand for different
widths of material, and self-adjusting for minor variations, substantially as described
and shown, with the object and for the purpose set forth.
9. The arrangement of the two side cutter heads N and O, their fences N¹
and O', (with or without lead-lined faces), and the concentrically hinged pressure-
block O³, substantially as described and shown, with the object and for the purpose
set forth.
10. The general arrangement of the whole of the enumerated parts of the
machine, substantially as described and shown, with the object and for the purpose
set forth.
