Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "AN
IMPROVED MACHINE FOR CUTTING, DRILLING, AND SHAPING WOOD AND METALS."
-A communication from abroad by Dominique Jules Bouchot,
of Void (Meuse), France.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition,
on the 13th November 1869.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN IM-
PROVED MACHINE FOR CUTTING, DRILLING, AND SHAPING WOOD AND METALS," a
communication to mo from abroad by Dominique Jules Bouchot, of
Void (Meuse), France, to be as follows:-
The machine for cutting wood and metal, the subject of this Invention,
is of incontestable usefulness and unites in its construction exceptional

page_text: advantages. It is graceful in form, is very light in proportion to its
size and its mechanism is of great simplicity. It further presents the
inappreciable advantage that it can be instantly transformed by a simple
successive transposition of the driving belt and of the tools which it is
desired to set at work.
By reason of the special arrangements given to the setting or stocks
of the said tools as well as to the framing of the machine a single
workman may obtain at will according to requirement and without
difficulty or fatigue an alternate sweep saw, a drilling machine, a circular
saw for all purposes, the particular arrangements of which is defined in a
subsequent paragraph, a lathe for curved mouldings, and an endless saw,
in fact, experience alone will determine all the tools which may be fitted
to this machine and which would be successively actuated as well as the
preceding by the same mechanism.
The frame A (Fig. 1 Sheet 1 of the accompanying Sheets of Drawing)
which receives the mechanism, the tools, and the pieces of wood or
metal to be operated upon is of cast iron in order however to lessen its
entire weight, the large lateral cross beams are replaced by pieces of
wood B of sufficient thickness to ensure the requisite strength; this
substitution is however optional.
The frame carries the following pieces:-A curved cast iron support C
with its base upon the aforesaid frame; its shape is such that its summit
terminates at the proper distance for receiving a wooden beam D or
upper balance beam; this latter in addition to its inherent functions is
further utilized in two ways. In the first place it supports a lever and
its pivot E as well as a graduated upright, the whole of wood. In the
second place it receives in consequence of the arrangement given to its
forward end a steel plate G ending in a piece of the same metal and
constituting one of the branches of the stock of the sweep saw. This
plate is moveable and is fixed by the aid of a wooden wedge H, and a
metal staple set on the thickness of the hooked end of said balance beam.
For this purpose it is slid into this staple to the extent necessary for the
tension of the saw, and is there fixed by a screw placed exactly in the
middle of the thickness of the head of the balance beam and at the
height of the aforesaid staple. This screw is inserted in the orbicular
holes made for this purpose in the body of the plate. To do away with
the oscillations produced by the vibration and prevent the plate escaping
from the screw use is made of the wooden wedge above mentioned.
It is

page_text: placed between the plate and the front cross piece of the staple and firmly
pressed down so as to completely press the blade against the end of the.
beam. The drilling or boring machine is also fixed to the curved support
C, of which it occupies the right side; it is composed like all others
of a horizontal fly wheel I driven by a crank acting on a bevel wheel or
a toothed segment according to circumstances. It may be constructed
so that the bit descends on to the picce to be operated upon, or on.
the contrary so that this piece meets it, which is the case in the present
instance, the picce rests on a wooden table fixed to an iron rod J,
descending along the right side of the machine and abutting against a
strap (K, Fig. 2,) on which it rests. This strap rises along the lateral
cross piece of the framing, passes over a small moveable drum L set in
the actual thickness of the cross piece, it then redescends and is fixed to
a small treadle M, which by the pressure of the foot communicates an
ascending motion to the rod, and consequently to the table N and the
piece to be drilled. In order that this piece may rise and lower squarely
it has at one of its angles a small rod passing into an opening made for
this purpose in the framing. The upper balance beam is carried on an
axle fixed to the curved support C; it rests on a bearing O fitted in the
centre of the beam. The lever, its support, and the graduated upright
which it upholds serve to give the requisite tension to the band or cord,
and that by the aid of the teeth in the lever and on the aforesaid upright.
The tension cord or band comes on to the lower balance beam P arranged.
like the preceding, and also receiving one of the branches of the stock
of the saw, but fixed in a permanent manner at the point where the
tension cord ends, there is a connecting rod R communicating with an
eccentric S receiving motion from the driving belt T which passes
over its grooved pulley and the main driving wheel U of the fly,
which also has two grooves, of which the usc will be herein-after
explained. A treadle V placed on the right side serves to give motion
to the fly which transmits it to the eccentric and so on. The frame
carries on the same side and at the upper angle of the back a vice with
eccentric intended for setting and giving the direction to the saws. This
vice is a fixture and its use is very easy. On the opposite side there is
an endless chain X passing over a small toothed wheel Y fixed to the
driving shaft, and over a second wheel Z of larger diameter occupying
the angle opposite to the vice and communicating rotation by the aid
of its crank. The object of this application is to increase the power
and facilitate operating on large pieces of wood or metal.

page_text: It is needless to describe the circular plate as it is of the same shape at
those hitherto used, it is however set so as to admit of ready removal and
replacing. The plate is furnished with a circular scale and has a nut
serving to give it more or less inclination. To obtain the developement
of power required for large pieces a return pulley is placed against the
inside of the left lateral side of the frame; it is fixed on a grooved iron
plate sliding against a rod fixed to the frame; a nut on the outside serves
to fix the position of this pulley according to requirement. By dis-
placing the sweep saw and its plate the frame may receive the circular
saw, of which the following is a description:-This piece specially
arranged and one of the distinctive characteristics of this innovation is
composed of a wooden framing having its two sides raised higher than the
cross pieces J (Fig. 4) which form the two other faces, a third cross
piece is placed between these two latter and supports the pulley of the
axle of the saw. The upper plate M' opens or closes like a lid which is
the motive for diminishing the height of the cross pieces as the above
mentioned pulley must be shut up within it. The horizontal shaft
driven by this pulley in placed in the direction of the breadth of the
frame, beyond which the end carrying the saw passes, the other end
abutting against the inside of the frame, where owing to its conical shape
at this point it pivots in a steel socket riveted to the frame. To set this
novel saw at work it is necessary to alter the arrangement of the driving
belt, firstly, it must be removed from the pulley of the eccentric and
from the smallest of the grooves of the driving wheel to be replaced on
the largest and on the pulley of the horizontal shaft of the circular saw.
These arrangements made the return pulley will be so placed that it
brings great tension upon the cord by pressing upon that part of it
nearest to the front of the frame. This action must be reversed
when using the lathe for curved mouldings, the same band is used
for driving the endless saw. The upper plate is composed of two pieces
at a distance apart regulated by the plane of the saw and united by
hinges, an arrangement explained by the succeeding paragraph. This
plate receives two guides and their accessaries and is supported from the
inside when uplifted by a shifting wooden block close to the inner cross
piece. Finally, the entire piece is secured to the framing by two pins
placed on the sides towards the front, one on the right the other on the
left, in grooves made in the framing for this purpose.
The apparatus being set up, and ready for working, attention will
first be drawn to the edge of the saw, which is more or less displayed

page_text: accordingly as the upper plate or table is more or less raised to the guide
on the right made in four pieces, the large groove of copper or iron
serving to direct the right hand guide and its graduated plate, the object
of which is to give various positions to the guide, its stop nut, which
fixes the position of this latter, and lastly to the guide itself set on a.
pivot towards its right end so that it can describe a semicircle..
There will next be observed a second guide placed on the left; this left
guide serves for working pieces of an equal breadth; it is as regards the
first a parallel guide; its object is to facilitate the working of stronger
pieces and to obtain broader pieces. Its position on edge gives it greater
resistance without increasing its weight, and its easy displacement by
means of the groove A' (Fig. 3) in which it plays secures. important
advantages. Further the groove in question forms the fourth side of an
iron square the corresponding side of which B', is fixed on the plate, and
the two lateral sides formed by connecting rods C and D¹; the arrange-
ment of which permits the guide in question to be brought nearer to or
moved further from the saw. It is easy to comprehend the movement
produced by these connecting rods, the side opposite the guide being that
which receives the moveable guide fixed to the aforesaid connecting, rods,
it follows that if an oblique position be given to these latter they
necessarily cause the guide to recede from the saw to the extent of the
difference produced in relation to the perpendicular by the new position
of the connecting rods, in the same way that the more these are raised
in bringing them back to their primitive position the nearer they come
to the guide, and the more perpendicular the position they assume.
the guide notwithstanding its displacement constantly maintains a
position parallel to the saw it always gives a regular bearing. The stop
is formed by a winged nut along which slides a groove in the form of
an arc starting from the left connecting rod and ending at the piece
opposite the guide. A second are or segment is also placed on the right
of the table like the preceding; it is furnished with a groove G¹ (Fig. 5),
and a stop nut; it permits more or less inclination to be given to this.
moveable part of the table in order to obtain bevels of different degrees..
Lastly, a forked rod also provided with a stop nut and fitted under and
on the front part of the upper table slides along the screw placed
outside, it serves to raise the upper plate when required, and in such a
manner as to progressively lessen the cut of the saw, which being fixed
beneath the plate it is evident that the more the plate is raised less is
As

page_text: the scope for the action of the saw upon the piece being operated upon.
By this means it is casy to cut sheets more or less thick and very fine
hollow mouldings. The right hand guide is of unquestionable usefulness;
it multiplics itself by simply shifting, and offers many different cuts.
It must not be forgotton that this guide varies circularly on its
graduation plate by reason of the circular groove made for this purpose,
that this plate itself slides at will in the vertical groove, and finally that
its stoppage is effected with that of the guide by the same nut.
Now if the workman desires to make a straight cut it is only
necessary to leave the guide in its habitual position, in other words, that
it should be fixed perpendicularly to the large groove. To make chamfers
the free end of the guide must be directed more or less obliquely forward
or backward according to the direction required, care being had to secure
it in its new position by the aid of the nut. An incalculable number
of different angles may be thus obtained. By the aid of these various
positions and of the inclination more or less great of the table supporting
the work bevels may be obtained of any degree of inclination. The
frame may also receive on the circular saw being removed a lathe for
making curved mouldings, the form of which lathe is too well known
to need describing here, it is, however, important to observe that it is
actuated by the same mechanism by simply placing the driving belt as
described in a preceding paragraph.
Finally, in lieu of this latter apparatus the mechanism may receive an
endless saw the stock of which is attached to the base of the frame of
the main machine by means of four key bolts, this being effected very
quickly on the spot. A wooden table J (Fig. 8, Sheet II,) is then
placed, this table being divided into two parts for the passage of the saw
.blade, the same belt which drives the alternating saw, the circular saw,
and the moulding lathe also serves for working this saw. A wooden
shutter or guard is placed before the saw to prevent accidents. To file
the saw the vice carried by the framing is dismounted and bolted at the
spot G, so that the blade of the saw is in the jaw of the vice. If it is
preferred to file the saw in a horizontal position the keys are removed,
the stock is set on the frame, and the saw is then as high as the vice,
.which remains in its usual position.

Y, Z, F, G, the functions of which are above set forth.
The frame A (Figure 1) which receives the mechanism, thic tools, and
the pieces of wood or metal to be operated upon is of cast iron; in order
however, to lessen its entire weight the large lateral cross beams are
replaced by pieces of wood B of suflicient thickness to ensure the

page_text: requisite strength; this substitution is however optional. The frame
carries the following pieces:-A curved cast-iron support C with its
base upon the aforesaid frame. Its shape is such that its summit
terminates at the proper distance for receiving a wooden beam D or
upper balance beam. This latter, in addition to its inherent functions,
is further utilized in two ways: in the first place it supports a lover
and its pivot E as well as a graduated upright, the whole of wood; in
the second place it receives in consequence of the arrangement given to
its forward end a steel plate G ending in a piece of the same metal, and
constituting one of the branches of the stock of the sweep saw; this plate
is moveable and is fixed by the aid of a wooden wedge H and a metal
staple set on the thickness of the hooked end of said balance beam.
For this purpose it is slid into this staple to the extent necessary for the
tension of the saw, and is then fixed by a screw placed exactly in the
middle of the thickness of the head of the balance beam and at the
height of the aforesaid staple. This screw is inserted in the orbicular
holes made for this purpose in the body of the plate. To do away with
the oscillations produced by the vibration and prevent the plate escaping
from the screw use is made of the wooden wedge above mentioned;
it is placed between the plate and the front cross piece of the staple
and firmly pressed down so as to completely press the blade against the
end of the beam. The drilling or boring machine is also fixed to the
curved support C of which it occupies the right side; it is composed
like all others of a horizontal fly wheel I driven by a crank acting on
a bevel wheel or a toothed segment according to circumstances. It may
be constructed so that the bit descends on to the piece to be operated
upon or on the contrary, so that this piece meets it, which is the case
in the present instance. The picce rests on a wooden table fixed to au
iron rod J, descending along the right side of the machine and abutting
against a strap (K, Figure 2,) on which it rests; this strap rises along
the lateral cross piece of the framing, passes over a small moveable
drum L set in the actual thickness of the cross piece; it then redescends
and is fixed to a small treadle M, which by the pressure of the foot
communicates an ascending motion to the rod and consequently to the
table N and the picce to be drilled. In order that this piece may rise
and lower squarely it has at one of its angles a small rod passing into an
opening made for this purpose in the framing. The upper balance beam
is carried on an axle fixed to the curved support C; it rests on a bearing
O fitted in the centre of the beam. The lever, its support, and the

page_text: graduated upright which it upholds serve to give the requisite tension
to the band or cord, and that by the aid of the teeth in the lever and
on the aforesaid upright. The tension cord or band comes on to the
lower balance beam P arranged like the preceding, and also receiving
one of the branches of the stock of the saw, but fixed in a permanent
manner at the point where the tension cord ends there is a connecting
rod R communicating with an eccentric S, receiving motion from the
driving belt T which passes over its grooved pulley and the main driving
wheel U of the fly, which also has two grooves of which the use will be
hercin-after explained. A. treadle V placed on the right side serves
to give motion to the fly which transmits it to the eccentric, and so on.
The frame carries on the same side and at the upper angle of the back
a vice with eccentric intended for setting and giving the direction to
the saws; this vico is a fixture and its use is very casy. On the
opposite side there is an endless chain X passing over a small toothed
wheel Y fixed to the driving shaft, and over a second wheel Z of larger
diameter occupying the angle opposite to the vice, and communicating
rotation by the aid of its crank. The object of this application is to
increase the power and facilitate operating on large pieces of wood or
metal. It is needless to describe the circular plate as it is of the same
shape as those hitherto used; it is, however, set so as to admit of ready
removal and replacing. The plate is furnished with a circular scale
and has a nut serving to give it more or less inclination. To obtain the
developement of power required for large pieces a return pulley is placed
against the inside of the left lateral side of the frame; it is fixed on
a grooved iron plate sliding against a rod fixed to the frame; a nut on
the outside serves to fix the position of this pulley according to require-
ment. By displacing the sweep saw and its plate the frame may receive
the circular saw, of which the following is a description:-This piece
specially arranged and one of the distinctive characteristics of this
innovation is composed of a wooden framing having its two sides raised
higher than the cross pieces J (Figure 4) which form the two other
faces. A third cross piece is placed between these two latter and
supports the pulley of the axle of the saw. The upper plate M' opens
or closes like a lid which is the motive for diminishing the height of
the cross piece as the above mentioned pulley must be shut within
it. The horizontal shaft driven by this pulley is placed in the direction
of the breadth of the frame beyond which the end carrying the saw
passes, the other end abutting against the inside of the frame, where,
up

page_text: owing to its conical shape at this point it pivots in a steel socket riveted
to the frame. To set this novel saw at work it is necessary to alter the
arrangement of the driving belt. Firstly, it must be removed from the
pulley of the eccentric and from the smallest of the grooves of the
driving wheel to be replaced on the largest and on the pulley of the
horizontal shaft of the circular saw. These arrangements made, the return
pulley will be so placed that it brings great tension upon the cord by
pressing upon that part of it nearest to the front of the frame. This
action must be reversed when using the lathe for curved mouldings;
the same band is used for driving the endless saw. The upper plate is
composed of two pieces at a distance apart regulated by the plane of
the saw, and united by hinges, an arrangement explained by the suc-
ceeding paragraph. This plate receives two guides and their accessaries
and is supported from the inside when uplifted by a shifting wooden
block close to the inner cross piece. Finally, the entire piece is secured
to the framing by two pins placed on the sides towards the front onc
on the right, the other on the left, in grooves made in the framing for
this purpose.
The apparatus being set up and ready for working attention will first
be drawn to the edge of the saw, which is more or less displayed,
accordingly as the upper plate or table is more or less raised to the guide
made in four picces, the large groove of copper or iron serving to direct
the right hand guide and its graduated plate, the object of which is to give
various positions to the guide, its stop nut, which fixes the position of this
latter, and lastly to the guide itself set on a pivot towards its right end
so that it can describe a semicircle.
There will next be observed a second guide placed on the left. This
left guide serves for working pieces of an equal breadth; it is as
regards the first, a parallel guide; its object is to facilitate the working
of stronger pieces and to obtain broader pieces. Its position on edge
gives it greater resistance without increasing its weight and its casy
displacement by means of the groove A¹ (Figure 3) in which it plays
secures important advantages. Further, the groove in question forms the
fourth side of an iron square, the corresponding side of which B', is fixed
on the plate, and the two lateral sides formed by connecting rods C¹ and
D', the arrangement of which permits the guide in question to be brought
nearer to or moved further from the saw. It is easy to comprehend
the movement produced by these connecting rods, the side opposite

page_text: the guide being that which receives the moveable guide fixed to the
aforesaid connecting rods, it follows that if an oblique position be given
to these latter they necessarily cause the guide to recede from the saw
to the extent of the difference produced in relation to the perpendicular
by the new position of the connecting rods, in the same way that the
more these are raised in bringing them back to their primitive position
the nearer they come to the guide, and the more perpendicular the
position they assume. As the guide, notwithstanding its displacement,
constantly maintains a position parallel to the saw it always gives a
regular bearing. The stop is formed by a winged nut along which slides
a groove in the form of an are starting from the left connecting rod and
ending at the piece opposite the guide. A second arc or segment is
also placed on the right of the table like the preceding; it is furnished
with a groove G' and a stop nut; it permits more or less inclination to be
given to this moveable part of the table in order to obtain bevels of
different degrees. Lastly, a forked rod also provided with a stop nut
and fitted under and on the front part of the upper table slides along the
screw placed outside. It serves to raise the upper plate when required
and in such a manner as to progressively lessen the cut of the saw,
which being fixed beneath the plate it is evident that the more the plate
is raised less is the scope for the action of the saw upon the piece being
operated upon. By this means it is easy to cut sheets more or less thick
and very fine hollow mouldings. The right hand guide is of un-
questionable usefulness; it multiplies itself by simply shifting, and
offers many different cuts. It must not be forgotten that this guide
varics circularly on its graduation plate by reason of the circular groove
made for this purpose, that this plate itself slides at will in the vertical
groove, and finally that its stoppage is effected with that of the guide
by the same nut.
Now if the workman desires to make a straight cut it is only necessary
to leave the guide in its habitual position, in other words, that it should
be fixed perpendicularly to the large groove. To make chamfers the
free end of the guide must be directed more or less obliquely forward
or backward according to the direction required, care being had to
secure it in its new position by the aid of the nut. An incalculable
number of different angles may be thus obtained. By the aid of these
various positions and of the inclination more or less great of the table
supporting the work bevels may be obtained of any degree of inclination.

page_text: The frame may also receive on the circular saw being removed a lathe
for making curved mouldings, the form of which lathe is too well
known to need describing here; it is, however, important to observe
that it is actuated by the same mechanism by simply placing the driving
belt, as described in a preceding paragraph.
Finally, in lieu of this latter apparatus the machine may receive an
endless saw, the stock of which is attached to the base of the frame of
the main machine by means of 4 key bolts I', this being effected very
quickly on the spot. A wooden table J¹ (Figure 8) is then placed, this
table being divided into two parts for the passage of the saw blade; the
same belt which drives the alternating saw, the circular saw, and the
moulding lathe also serves for working this saw. The hinges K serve
for fixing a wooden shutter or guard before the saw to prevent accidents.
To file the saw the vice carried by the framing is dismounted and
bolted at the spot I, so that the blade of the saw is in the jaw of the
vice. If it is preferred to file the saw in a horizontal position the keys
are removed, the stock is set on the frame, and the saw is then as high
as the vicc, which remains in its usual position.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, I wish it to be understood that
I claim, the particular arrangement of the various parts of the machine
which permits it to comprise an alternate sweep saw, a drilling machine,
a vice for sharpening and setting the tools, and a crank or endless chain
movement if it is desired to dispense with the treadle, also the addition
to the same machine without modification and using the same fly wheel
and driving belt of a lathe, a circular saw, a small machine for curved
mouldings, and an endless saw, also of such other tools for cutting,
drilling, or shaping wood and metals as may be found applicable thereto,
the whole substantially as herein-before described and illustrated on the
accompanying Drawings.
In witness whereof, I, the said William Edward Gedge, have here-
unto set my hand and seal, this Eleventh day of May, in
the year of our Lord One thousand eight hundred and seventy.
