Improvements in Combination Woodworking Machines for Planing
Thicknessing, Moulding and Tenoning, and Variety Wood
Working.
I, EDWARD GEORGE 33 Westgate Road in the City of Newcastle-upon-Tyne,
Estate Agent, do hereby declare the nature of this invention to be as follows:-
The invention relates to certain improvements in a combined thicknessing,
planing and moulding band and circular sawing and tenoning machine for variety
5 woodworking, including surface planing, jointing thicknessing, beveling, stop
chamfering, tonguing, grooving, rabbeting, sawing, tenoning, cutting and scribing
shoulders, boring, moulding, and variety wood working, straight, circular or
irregular tracery and trenching.
The improvements consist in the first instance in fitting three spindles in
bearings, two horizontal (marked AAA and B B on No. 1 Sheet) and one
vertical (marked CC on Nos. 1 and 2 Sheets) running in vertical slides round
rods or screws (marked DD and EE on Sheet No. 1) which rise and fall by the
action of a single or double screw geared to a handwheel (marked F on Sheet 1);
with this arrangement the spindle carrying the usual moveable planing, tenoning or
moulding blocks (marked M M on Sheet 2) saw cutter and tenoning blocks or boring
tools can be raised or lowered and adjusted horizontally, thus converting the
machine into a thicknessing planing, sawing, moulding and tenoning machine
without complication or loss of time in changing to suit various kinds of work
required as is usual in present combination machines.
The feed rollers (marked K K on No. 2 Sheet) which are fixed in sockets with
spiral spring are driven by an endless chain connected to a worm and cogged
wheel fixed in a slide (marked G on Sheet 1) arranged to rise and fall to the
required thickness which is driven by ordinary belt from countershaft, by this
arrangement the cutter blocks may be raised or lowered and adjusted, as shewn
by handwheel (marked Fon Sheet No. 1) converting the machine at once into a
complete power feed, thicknessing and moulding machine with adjustable feed and
delivery rollers of indiarubber or iron (marked KK on No. 2 Sheet) which are
raised or lowered by the same handwheel (marked F on No. I Sheet) that raises
and lowers the spindle (marked B B on Sheet No. 1) and these rollers are divided
nto four the outside pair can be taken off when not required or the whole can
e worked together.
The splinter bar attached to thicknessing cutter block is so arranged on a
entre that it will revolve round the cutter block without any adjustment (marked
IH on No. 1 Sheet) which prevents its coming in contact with the cutter block
nives thus obviating all danger of injury to the machine or the operator.
The vertical spindle attached to the end of the machine (marked CC on
and 2 Sheets) for tenoning scribing can also be used for irregular moulding,
enching, tracery, and can also be used as a side cutter in connection with the
at or inside cutter block for straight or irregular mouldings by power or hand
ed. If required two vertical spindles can be attached.
The surface planer (marked L on No. 1 Sheet) when attached to the machine
e tables can be raised lowered or drawn back by means of handwheels (marked J
No. 1 Sheet) at the front of the machine acting on a wedge shaped bracket
ding on an inclined plane without having to remove saw except when tenoning.
The machine can be made any size either with or without a surface planer or

intended for sawing tenoning thicknessing moulding by power feed which this
Patent is intended to cover.

Improvements in Combination Woodworking Machines for Planing,
Thicknessing, Moulding and Tenoning. and Variety Wood
Working.
I, EDWARD GEORGE, of 33 Westgate Road, in the City and County of
Newcastle-upon-Tyne, Estate Agent, do hereby declare the nature of said inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The invention relates to certain improvements in a combined thicknessing,
planing, moulding, sawing and tenoning machine, for variety wood-working;
including surface planing, jointing, thicknessing, beveling stop champhering,
tongueing, grooving, rabbiting, sawing, tenoning cutting and scribing shoulders,
boring, moulding, straight circular or irregular tracing or tracery work and
trenching.
Referring to 4 sheets of drawings herewith which are supplementary to and
may he taken as superseding those filed with my Provisional Specification, as
representing a machine made according to my invention in its matured form;
Fig. 1. Sheet 1. is an elevation of one end of a machine;
Fig. 2. Sheet 2. is a side elevation of Fig. 1. looking from right hand in the
direction of the arrow.
Fig. 3. Sheet 3. is a side elevation of Fig. 1. looking from left hand side in the
direction of the dotted arrow and
Fig. 4. Sheet 4. is a plan of the machine.
The same letters of reference apply to similar parts on all the figs. where such
parts are shewn.
There are 3 horizontal driving spindles, A B and D, and one vertical
spindle C which carry the tools required for the various processes performed by
the machine.
The horizontal spindle B carries the thicknessing cutter block H and, when
required, the moulding cutter block M shewn on plan Fig. 4 and also carries the
splinter bar S B which is radially adjustable so as to cover and protect the cutters
of block H. The spindle B with the tools which it carries and the splinter bar,
as also the feed rollers K K are adjustable vertically for thicknessing or moulding
(as the case may be) in a sliding head SH working in a frame, bolted to the table
of the machine, by the screw hand wheel W.
The splinter bar SB around the thicknessing cutter block H H is so arranged on
a centre that it can be turned round the cutter block to cover the same more or less
and can be fixed in position, the distance of the block from the splinter bar being
such as to prevent the splinter bar being accidentally brought in contact with
the cutter block knives thus obviating all risk of injury to the machine or the
operator.
To allow for the different thicknesses of wood it is necessary to provide an
adjustable driving power for the feed rollers K K which is effected by an endless
chain EC passing over chain pullies P on roller spindles and driven by worm
gearing WG in the case G, which is arranged to slide in guides and kept tight by
springs S so as to adjust the chain to the varying thicknesses of wood, a distance
bar D B keeping the centres fixed when adjusted. This mechanism is shewn on
left hand side of Fig. 1. Sheet 1 and, more clearly, on Fig. 3. Sheet 3. Springs
by which the feed rollers K K are pressed into frictional contact with the timber

head SH carrying the thicknessing cutter blocks H H the splinter bar SB,
The sliding
the feed rollers K K with the moulding cutter block M on its outer end, and the
feed rollers, required for certain processes performed by this portion of the improved
5 combination machine, forms an important feature in my invention, apart from the
general combination of mechanism constituting the machine. The adjustment of
the feed rollers KK is allowed for by the sliding upward or downward of the
chain sheaves which carry the lower loop of the endless chain, in the slide case G
the normal length of the chain being adjusted by the distance bar D B. The
0 spindles of the feed rollers K K are extended to receive feed rollers on their ends,
see Figs. 1 and 4, when moulding is required to be done.
The vertical spindle CC attached to the end of the machine for "tenoning,"
scribing, grooving &c. can also be used as a side cutter in connection with the
outside moulding or tenoning block M, or with the inside cutter block HH, for
straight or irregular moulding. If required another vertical spindle can be
attached to operate on the opposite side of the thicknessing table. This spindle CC
runs in bearings in the vertical slide frame DD which can be adjusted horizontally
in the frame by a screwed spindle working in a tapped nut by the hand wheel W
and vertically by a screwed spindle behind, by means of the hand wheel W³ shewn
below it. The spindle CC carries at top end the various cutting tools required
for different processes as grooving scribing &c. The horizontal spindle A (see
Fig. 2) carries the tenoning blocks T B and the circular saw CS and is carried in
blocks mounted on the screw threaded shafts EE by which the spindle can be
raised or lowered. The screw threaded shafts E are revolved together in either
direction by the bevel wheel B W and the hand wheel W+.
The surface planer L shewn by dotted lines Figs. 2, 3 & 4 is driven by the
horizontal shaft D. The adjustment of the sliding table T of the surface planer L
(shown in dotted lines as attachable to the machine frame) is necessary to regulate
the depth of cut of the planing knives and the raising and lowering is effected by
screws worked by hand wheels W secured in lugs on the bracket table T¹ and
working in threaded lugs in the sliding table. Thus the latter can be adjusted to
the required cut or when the planer is not in use, can be raised to protect the
planer from injury or accident.
The machine can be made any size either with or without a surface planer (as
will sometimes be preferred and as shewn as a separate portion) or vertical spindle
moulder, without interfering with the other parts of the machine intended for
sawing, tenoning, thicknessing, moulding; all which processes this invention is
intended to cover in the various combinations of the working parts.
The machine is fitted with all the usual and requisite fences, cramps and other
parts and with belt sheaves for driving not distinguished by letters. Grooving and
scribing or undercutting is done by suitable revolving tools carried in holders fixed
on the top end of the vertical spindle C (which is adjustable vertically as described)
he wood being operated upon being guided against the adjustable fence F'.
In producing tracing or tracery work revolving tools are employed in a similar
nanner, curved and other fancy shapes being cut by guiding the work by hand
gainst the tools.
Having now particularly described and ascertained the nature of my said inven-
ion and in what manner the same is to be performed I declare that what I
laim is : :-
1st. In combination wood working machines the application to the thicknessing,
oulding and tenoning portion of the machine of a sliding head in which, by the
peration of a hand wheel W', the shaft B carrying the thicknessing cutter
lock H H, the splinter bar S B and moulding or tenoning block M, together with
e feed rollers K K, are simultaneously adjusted to the thickness of the wood to
e operated upon, in combination with the endless chain and adjustable gearing in
e sliding case G, substantially as described and shewn.
