PROVISIONAL SPECIFICATION.
An Improved Machine with Rotating Tool for Working Wood,
Marble, Metals, and other Materials.
We, PIERRE JURY Fils, Machine Sawyer, of 70 Rue d'Avron and EDOUARD
ANGER, Mechanic, of 197 Boulevard Voltaire, both of Paris in the Republic of
France, do hereby declare the nature of this invention to be as follows:-
In the working of wood, for example, when using a somewhat heavy or
cumbersome piece, such piece cannot be shaped by the machines in ordinary use
which are fixtures; that is the case with a staircase string board or with an arm
chair.
The invention forming the subject of the present application for patent relates
to an arrangement of rotary tool, essentially movable, operated by a mechanical
motor, conducted and directed by the workman, and having no bearing point other
than the material to be worked.
A method of carrying our invention into effect is illustrated in the accompanying
drawings in which
Fig. 1 is a front elevation of a complete apparatus constructed according to our
invention as applied to the working of wood.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a transverse section drawn on the line 1. 2 of Fig. 1.
Fig. 4 shows separately a longitudinal section of the details of the tool carrying
shaft receiving the cutter or tool carrier.
Fig. 5 shows separately the key for rotating the shaft upon which the tool
carrier is screwed.
In the various figures similar letters of reference indicate like parts.
As will be seen in the drawing, this apparatus consists of a framing a furnished
at its ends with handles b; this framing a comprises a slide c upon which the
carriages d can be moved by means of the regulating screws e.
Each of the
carriages d carries a slidef capable of transverse regulation by means of a regulating
screw and in this slide fis placed a contact guide h, furnished at its upper part
with a spring i.
The framing a carries two blocks k whose bearings receive the tool carrying
shaft . This shaft carries the pulley m and is hollow throughout its entire
length.
One part of its bore is cylindrical to receive the shaft n which has at one of its
ends a screw threaded part o screwing into one end of the tool carrier p.
The other part of the hore of the tool carrying shaft is conical and serves to
receive the corresponding part of the tool carrier p, which receives the tool or
cutter q, properly so called, which is fixed thereto by means of a screw r.
The key s has a small square part fitting a corresponding space t formed in the
outer end of the shaft n.
Rotary motion of the tool carrier is obtained by cord or strap or by means of
one or several transmitting gearings fixed to the apparatus itself or in the
neighbourhood of the piece to be worked.
It may also be obtained directly by a motor operated by electricity, compressed
air, or steam or by a turbine or other motor fixed to the apparatus itself in any
convenient manner.

page_text: From the foregoing, it will be understood that the apparatus being held in the
hands by the handles b and the tool g being rotated, the material to be worked
will be placed between the contact guides h which will have been regulated by
means of the screws e and g, so that the faces of the contact guides will follow
the outlines of the piece to be worked.
In order to prevent the tool g when working from penetrating too suddenly into
the material, the contact guides h give way transversely thus compressing the
springs and the action of these springs in tending to extend balances the weight of
the apparatus.
To change the tool, the tool carrier p is unscrewed by turning the shaft n by
means of the key 8.
The tool carrier may receive either a milling tool, a grinding wheel, a brush or
other tools appropriate to the kind of work to be produced and to the nature of the
material to be worked.
We would have it understood that the forms, arrangements, (shaft vertical
horizontal or inclinable in any direction) dimensions, details, accessories and
materials employed for the construction of our apparatus may be varied without
departing from the peculiar character of our invention.

An Improved Machine with Rotating Tool for Working Wood,
Marble, Metals, and other Materials.
We, PIERRE JURY Fils, Machine Sawyer, of 70 Rue d'Avron, and EDOUARD
ANGER, Mechanic, of 197 Boulevard Voltaire, both of Paris, in the Republic of
France, 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:-
In the working of wood, for example, when using a somewhat heavy or
cumbersome piece, such piece cannot be shaped by the machines in ordinary use,
which are fixtures; that is the case with a staircase string-board or with an
arm-chair.
The invention forming the subject of the present application for patent relates
to an arrangement of rotary tool, essentially movable, operated by a mechanical
motor, conducted and directed by the workman, and having no bearing point other
than the material to be worked.
A method of carrying our invention into effect is illustrated in the drawings
accompanying our Provisional Specification, in which :-
Fig. 1 is a front elevation of a complete apparatus constructed according to our
invention as applied to the working of wood.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a transverse section drawn on the line 1-2 of Fig. 1.
Fig. 4 shows separately a longitudinal section of the details of the tool-carrying
shaft receiving the cutter or tool-carrier.
Fig. 5 shows separately the key for rotating the shaft upon which the tool-
carrier is screwed.
In the various figures similar letters of reference indicate like parts.
As will be seen in the drawings, this apparatus consists of a framing a furnished
at its ends with handles b; this framing a comprises a slide c upon which the
carriages d can be moved by means of the regulating screws e.
Each of the

page_text: carriages d carries a slide ƒ capable of transverse regulation by means of a
regulating screw g, and in this slide fis placed a contact guide h furnished at its
upper part with a spring i.
The framing a carries two blocks whose bearings receive the tool-carrying
shaft. . This shaft carries the pulley m and is hollow throughout its entire
length.
One part of its bore is cylindrical to receive the shaft n, which has at one of its
ends a screw-threaded part o screwing into one end of the tool-carrier p.
The other part of the bore of the tool-carrying shaft is conical and serves to
receive the corresponding part of the tool-carrier p, which receives the tool or
cutter g, properly so called, which is fixed thereto by means of a screw r.
The key s has a small square part fitting a corresponding space t formed in the
outer end of the shaft n.
Rotary motion of the tool-carrier is obtained by cord or strap, or by means of
one or several transmitting gearings fixed to the apparatus itself or in the
neighbourhood of the piece to be worked. It may also be obtained directly by a
motor operated by electricity, compressed air or steam, or by a turbine or other
motor fixed to the apparatus itself in any couvenient manner.
From the foregoing it will be understood that the apparatus being held in the
hands by the handles b, and the tool g being rotated, the material to be worked
will be placed between the contact guides h, which will have been regulated by
means of the screws e and g, so that the faces of the contact guides h will follow
the outlines of the piece to be worked.
In order to prevent the tool q, when working, from penetrating too suddenly
into the material, the contact guides h give way transversely, thus compressing the
springs, and the action of these springs in tending to extend balances the weight of
the apparatus.
To change the tool, the tool-carrier p is unscrewed by turning the shaft n by
means of the key s.
The tool-carrier may receive either a milling tool, a grinding wheel, a brush or
other tools appropriate to the kind of work to be produced and to the nature of the
material to be worked.
We would have it understood that the forms, arrangements, (shaft vertical,
horizontal or inclinable in any direction) dimensions, details, accessories and
materials employed for the construction of our apparatus, may be varied without
departing from the peculiar character of our invention.
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 :-
and
1. In an arrangement of rotary tool for working wood, marble, metals, and other
materials, the combination of a framing a furnished with handles b, a slide
carriages d mounted on such slide and capable of adjustment thereon by means of
