Improvements in Wood-working Machines.
I, EDWARD YOUELL, Joiner and Machinist, 53 Trafalgar Road, Old 'Kent
'Road, Surrey, do hereby declare the nature of 'this invention to be as follows:-
My invention relates to wood-working machines and is chiefly designed to provide
an improved machine for the production of straight, circular or curvilinear
douldings or for moulding wreaths and ramps or moulding on surface to any sweep
or given line.
An important feature of my said invention is the provision which I make for
moving the rotary cutter or cutters towards and away from the work whilst the
machine is in 'motion, for the purpose of producing stopped mouldings and for other
purposes.
I accomplish this result by mounting the cutter-spindle in suitable bearings
which are so arranged that, whilst the said spindle is being driven at the desired
velocity, the said bearings and the spindle carried thereby can be moved up and
down, by means of a treadle or otherwise, relatively to the bed or table on which
the work is supported.
My said invention also comprises improvements whereby I am enabled to make
circular or segmental mouldings of any desired radius. And my said invention
further comprises other improvements hereinafter mentioned.
In the accompanying drawing I have shown, by way of example, one form of
my improved machine.
The cutter or cutters A are mounted on a horizontal steel spindle B, being
secured thereto by means of V-washers C and locking nuts and a screw-thread cut
on the spindle.
The spindle B runs in two gun-metal bearings D, D, attached to a double
slide E¹, E.
The bearings are fixed directly to the front slide E', which works on a back
slide E' in splayed runners. The front slide E' is lowered by means of a treadle
and chain F and is raised by means of strong spiral springs P. The back slide E
works in splayed runners fitted on the standard of the machine. This part of the
double slide is raised or lowered by means of a hand-wheel and screw G.
The screw and wheel G raises or lowers the whole of the double slide together,
i.e., the frout and back slide, whilst the treadle and chain act on the front slide
only The two slides can be fastened as one by a locking handle when stopped
moulding is not required.
The bearings D, D are fixed one at the extreme back and the other about the
centre of the slide E as shewn on the drawings, the one bearing being right outside
the table whilst the other passes up through a gap in the table as shewn.
The pulley H is between the bearings but beyond the table top. The fence is
hewn at K.
Attached to the side of the table and underneath it is a bar M in which is a
series of holes. To this bar a plate N can be screwed in order that circular
mouldings can be worked to any radius.
The machine is used as follows:-Should it be required to work a straight
moulding to any section, the cutters are fixed between the V-washers between the

page_text: bearings. The fence is then placed in the position required by the size of the
moulding. The cutters are then brought down to the required position by means
of the hand-wheel G. The wood to be moulded is then passed along the table in
the usual way, the machine being used as an underhand cutter.
Should it be required to work a circular or segmental moulding, the cutters are
fixed on the spindle by the V-washers outside the bearings. The cutters are then
brought down to the required position by means of the hand-wheel G. The
material to be moulded is then placed on the plate N which is fixed to suit the
required radius and the plate is worked round on its centre.
If it is a stopped moulding that is required, then the cutters are brought down
to the required position by means of the treadle F, and, when the treadle is
released, the spindle rises again, being forced up by means of the spiral springs P.
Should it be required to mould ramps or wreaths, a false top is placed over the
cutters and the material to be worked is passed over the top (the machine in this
case being used as an overhand cutter) and is guided by the workman to a fence or
pin as the case may be.
A circular saw can, if desired, be used on the aforesaid spindle, and likewise a
square planing or moulding block for bevelling, ploughing or the like.

1, EDWARD YOUELL, Joiner and Machinist, 53 Trafalgar Road, Old Kent Road,
Surrey, 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:―
My invention relates to wood-working machines and is chiefly designed to provide.
an improved machine for the production of irregular, straight, circular or
curvilinear mouldings or for moulding wreaths and ramps or moulding on surfaces
to any sweep or given line..
An important feature of my said invention is the provision of suitable means for
moving the rotary cutter-shaft towards and away from the work whilst the machine
is in motion, for the purpose of producing stopped mouldings and for other purposes
hereinafter explained.
I accomplish this result by mounting the cutter-shaft or spindle in suitable
bearings which are so arranged that, whilst the said shaft or spindle is being driven
at the desired velocity, the said bearings and the shaft or spindle carried thereby
can be moved up and down, by means of a treadle or otherwise, relatively to the bed
or table on which the work is supported.
My said invention also comprises improvements whereby I am enabled to make
circular or segmental mouldings of any desired radius. And my said invention
further comprises other improvements hereinafter mentioned.
In the accompanying drawing I have shown, by way of example, one form of my
improved machine.
Figure 1 is an end elevation of the said machine.
Figure 2 is a vertical section on the line a, a, Figure 1.
Figure 3 is a horizontal section on the line y, y, Figure 1.

Figure 5. a section on the line. a,, Figure 4, showing means for facilitating.
the production of circular, or segmental mouldings..
Figure 6 is.a plan, and
Figure 7 a section on the line x, x², Figure 6, showing, means for adapting the
machine for use with a circular saw.
Like letters indicate corresponding parts throughout the drawing.
In the machine shown in the drawing, the cutters A, A¹ are mounted on a
horizontal steel shaft or spindle B, being secured thereto by means of notched.
rings or V-washers C and of locking nuts a, b, fitted on screw-threaded parts of the
said shaft or spindle.
The shaft or spindle B is supported and rotates in two gun-metal or other suitable
bearings D, D¹, attached to a double slide E', E'.
The said bearings D, D' are attached directly to the front slide E¹, which works
on a back slide E in suitable guides or splayed runners.
The front slide E¹ is, so,
arranged that it can be pulled downward, by means of a foot-lever or treadle F
pivoted at F and connected with the slide by a chain F, and, when the treadle is,
released, the said slide will be raised by means of the spiral springs P. The back
slide E' works in suitable guides or splayed runners on the standard or frame Q of
the machine. This part of the double slide is so arranged that it can be raised or.
lowered by means of a screw G provided with a hand-wheel G'
The turning of the screw G by means of the wheel G' raises or lowers the whole..
of the double slide together, i.e. the front and back slides E¹, E', whilst the
treadle F and chain Fact on the frout slide only. The two slides are adapted
to be fastened together by a locking handle or bolt c so as to be movable or
adjustable by means of the hand wheel G¹like a single slide when stopped moulding
is not required.
The bearings D, D₁ are arranged one at the extreme back, and the other about.
the centre of the machine, the bearing D' being outside the table R whilst the
support of the bearing. D passes up through a gap in the table as shewn.
K is an

adjustable stop or più of suitable form secured to the table R for the
purpose of facilitating the production of curved mouldings of any radius or of
mouldings of irregular form by holding the wood to be worked against the said stop
or pin during the operation of producing the moulding. K' is an adjustable guard
plate or fence also secured to the table R by means of suitable bolts and which can
be used outside the bearings in place of the stop or pin K for the purpose of
producing straight mouldings.
The machine is used as follows:-
-
Should it be required to work an irregular, curvilinear or segmental moulding,
the cutters are fixed as at A between two of the V-washers in front of the
bearing D and the adjustable stop or pin K is fixed in the required position.
The cutter-shaft B is then adjusted to the required position by means of the
hand-wheel G' and screw G, and I am thus enabled to make irregularly curved
mouldings either on the top or bottom surface or on the outside and inside edges of the
material being worked whether the same be of regular thickness throughout or not.
To adapt the machine for working with facility circular or segmental mouldings
a device, such as that shown in Figures 4 and 5 is provided, comprising a bar M.
which is to be attached to the underside of the table R so that it extends in front
thereof. In this bar M is a series of holes M', in either of which a pivot-pin N
can be secured according to the radius of the desired circular or segmental
moulding. On the said pivot-pin N is fitted a frame S designed to be secured
to the piece d to be moulded or to a plate for carrying the said piece. The
material to be moulded is either placed on the said plate or secured to the
frame S which is secured by the pivot-pin N in a position to suit the required.
radius and the said frame is worked round on its centre or pivot-pin N..
:

page_text: Should it be required to work a straight moulding to any section, the cutters are
fixed as at A¹ between two of the V-washers situated between the bearings D.
The fence K is then secured in the position required by the size of the moulding.
The cutter-shaft B is then brought down to the required position by means of the
hand-wheel G and screw G. "The wood to be moulded is then passed. along
the table at any required angle in the usual way, such for example as by. means.of.
rollers mounted on springs or by springs only, the machine being used as an
underhand cutter although if desired it may be arranged to be used as an overhand
cutter.
If the wood to be moulded is too large to go under the spindle a false top can
be placed over the cutters and the work passed over the top using the machine
as an overhand cutter. The cuiters A can also be used for planing wood, "if
desired.
If in either of the above cases, a stopped moulding is required the slide E² is
adjusted to a suitable position by means of the screw G, the slide E' is unlocked
from the slide E2 and the cutters are brought down to the required position by
means of the treadle F. When the said treadle is released the cutters again rise,
the cutter-shaft being forced upward by means of the spiral springs P.
Should it be required to mould ramps or wreaths a false top is placed over the
cutters and the material to be worked is passed over the top (the machine in this
case being used as an overhand cutter) and is guided by the workman to a fence
or pin as the case may be.
A circular saw can, if desired, be used on the aforesaid spindle and likewise
a square planing or moulding block for bevelling, ploughing or the like.
adapt the machine for use with a circular saw, I find it advantageous to
secure, preferably on the front part of the table R a false-top, T, Figures 6 and 7,
having a slot T through which projects the circular saw V, the latter being secured
on the cutter-shaft B in place of the cutter A. A guard-plate or fence K³ is
secured on a rock-shaft K at one end of the false-top T so that it can be adjusted
towards or away from the saw V and so that it can be turned over away from and
below the level of the said false-top.
I sometimes form in the false-top T a groove T2 parallel with the saw V and
mount on the said table-top a slide W provided with a rib or projection fitting
in the said groove, so that a piece of wood to be sawn can, when placed on the said
slide, be very easily fed and guided in the proper manner to the saw.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
First. A wood-working machine in which a rotary cutter-shaft is movable or
adjustable towards and away from the work, substantially as hereinbefore
described, for the purpose of producing stop-mouldings.
Second. The combination, with the cutter-shaft. of the double slide, one
part of which carries the bearings for the said shaft and is adjustable relatively
to the other, the entire double slide being also adjustable relatively to the table of
the machine, substantially as, and for the purposes, set forth.
.
Third. The combination, with an overhung horizontal rotary cutter-shaft of an
adjustable pin secured to the table for the purpose of facilitating the production of
ramps and other irregular or curvilinear mouldings, substantially as herein before
described.
Fourth. The combination with a wood-working machine, of means, substantially
as herein before described, for facilitating the production of circular, or segmental
mouldings.
Fifth. The combination, with a wood-working machine, of means, substantially
as hereinbefore described, whereby the same is adapted for use with 8
circular saw.

page_text: Sixth. The improved wood-working machine constructed substantially as
described with reference to the accompanying drawing and operating as and for
the purposes above specified.
