Office of the Commissioners of Patents, with his Petition, on the 30th
July 1862. A communication from abroad by Joseph Bouton, of
Brussels, Mechanic.
I, FERDINAND CHARLES WARLICE, of 10, Alma Terrace, New Cross, in the
County of Kent, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY FOR DRESSING AND SHAPING STONE," being a
communication to me from abroad by Joseph Bouton, Mechanic, of Brussels,
to be as follows:-
My Invention consists in the more speedy and accurate dressing and shaping
of any description or quality of stone or marble used for building or other
purposes; it is not confined to the more efficient production of plain or flat
surfaces, but is equally adapted for the creation of complicated mouldings,
embracing any description of curve. I place the block of stone which is to be
shaped by means of my improved machinery, and which is marked A on the
annexed Diagram, on a turntable B. This turntable is placed on a movable
platform C. If the intention be merely to obtain flat or rectangular surfaces,
the turntable is made stationary, and on it is fixed the stone to be operated
upon, and when by a steady progressive movement imparted to the machine one
side of the stone has been subjected to the action of the tools D, which move
with the machine, the position of the turntable is changed so to allow the tools
to dress evenly the block of stone on another side. Besides this horizontal
movement of the machine, a movement which it possesses in common with

page_text: many other machines (an ordinary lathe, for instance) the tools may be
so regulated as to act in a vertical direction. Reference to the Diagram will
make this more intelligible.
E represents the elevation of an iron framing, the plan form of which is
circular; F is another iron framing, which is made to slide telescopically
within the aforesaid frame E; this sliding movement of the inner frame F is
effected by means of a screw G, which is fixed to the said frame. A wheel
and pinion marked respectively H and I, are adjusted on the outer frame E,.
which has only a horizontal movement, the screw G passing through the centre
of the wheel H. This wheel is made to raise or lower the screw, and with it
the inner frame F, to which it is fixed as above described. The tools D, which
are attached to the lower part of the sliding frame F are thus enabled to travel
and work vertically.
For circular dressing the rotary movement of the turntable provides. In
order to give the tools a proper inclination for forming curved mouldings or
ornaments, the upper part of the framing K which holds the tools D is adjusted
in a narrow circular slot or groove L cut in a segment or disk M. Thus the
'tools by moving in the circular groove may be inclined and operate at any
angle up to 45 degrees on either side of a perpendicular line imagined through
the points of the tools, these points being regarded as the centre of radiation.
The circular motion, which by means of the screw G may be given to the inner
framing F, to the lower part of which the tools are attached, permits the said
tools to assume a horizontal inclination; by these means the tools have free
play from one up to ninety degrees in all directions, the position of their points
with regard to the machine being invariable. The head of the tools is struck
by a hammer, the rapidity and force of the strokes. being regulated according
to the fineness contemplated in the work to be done or to the quality of the
stone to be operated upon.
