and Son, Patent Agents, 123, Chancery Lane, London, for the
Invention of "IMPROVEMENTS IN MEANS AND APPARATUS FOR DRESSING,
MOULDING, AND POLISHING STONE, MARBLE, AND OTHER SIMILAR SUBSTANCES."
-A. communication from abroad by François Bertrand, of Boulogne,
in the Empire of France, Mechanic.
Sealed the 25th May 1869, and dated the 26th November 1868.
PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition, on
the 26th November 1868.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent
5.Agents, 123, Chancery Lane, London, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MEANS AND APPARATUS FOR
DRESSING, MOULDING, AND POLISHING STONE, MARBLE, AND OTHER

page_text: SUBSTANCES," a communication to me from abroad by François Bertrand,
of Boulogne, in the Empire of France, Mechanic, to be as follows:-
This Invention relates to means and apparatus for dressing, moulding,
and polishing stone, marble, and other similar substances, and consists
in placing the stone or other substance on a moveable platform or turn-
table, and causing a suitable tool to revolve against the edge or surface
required to be dressed.
A frame constructed of wood or other suitable material and mounted
on wheels so that it can be transported easily from one place to another
carries the mechanism both for supporting and operating upon the stone
or other substance, and is composed of two main parts, which are held
together at the top by transverse bars or stays, and supports in suitable
bearings on either side two endless screws, on which work the screwed
bearings of a horizontal slide carrying the vertical tool holder. The said
tool holder consists of a shaft supported in bearings and having at its lower
end the socket or boss to which the rotary cutting tools are fixed, and at
its upper end a fly wheel, while between the bearings or on any other
suitable part of the shaft is a pinion or worm wheel gearing into other
pinions or worms receiving rotary motion from a pulley, to which power
is imparted in any known manner. The said tool holder is caused to
slide on its horizontal bars or slides by means of a worm and worm wheel
actuated by a hand wheel or other suitable device, and its vertical
motion is imparted to it by means of a scries of bevil and cog wheels
and pinions placed both on the said vertical screws and on a transverse
shaft operated by a hand wheel or other suitable device. On the lower
part of the frame is a strong platform having rails, on which run the
wheels supporting the truck for holding the stone or other substance.
The said truck, which may be moved backwards and forwards by means
of a screw or other suitable means, carries at one end a moveable
platform working at one end on a hinge or pivot, while the other end
may be raised and lowered as required by means of a lever, one end of
which works on a screw operated by hand or otherwise, and the other
end presses against the under side of the said platform, so that the
nearer the lower end of the lever approaches the movable end of
the platform the greater is the angle of the said lever with reference
to the screw, and in proportion therewith the upper end of the said lever
rises, carrying with it the movable end of the platform, so that the stone
or other substance placed thereon may receive any inclination in relation

page_text: to the vertical shaft carrying the cutting tool. At the other end of the
said truck is a turntable, rotated by means of a worm gearing into teeth
placed around its periphery, so that the stone or other substance may
present any or all of its sides or surfaces to the action of the rotary
cutting tool or tools, and the said turntable may be enclosed in any
suitable manner, so as to preserve the working parts from dust or other
injurious matter.
With this improved mechanism all kinds of dressing, moulding, and
polishing can be accomplished with the greatest ease and. exactitude,
thus saving much time and manual labour.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent
Office on the 25th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Edward Thomas Hughes, Her special licence
that I, the said Edward Thomas Hughes, my executors, administrators,
and assigns, or such others as I, the said Edward Thomas Hughes, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great. Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MEANS AND APPARATUS FOR DRESSING, MOULDING, AND POLISHING STONE,
MARBLE, AND OTHER SIMILAR SUBSTANCES," a communication to me from
abroad by François Bertrand, of Boulogne, in the Empire of France,
Mechanic, upon the condition (amongst others) that I, the said Edward
Thomas Hughes, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should

page_text: particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Edward Thomas Hughes, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Sheet of Drawings (that is to say) :-
This Invention relates to means and apparatus for dressing, moulding,
and polishing stone, marble, and other similar substances, and consists
in placing the stone or other substance on a movable platform or turn-
table and causing a suitable tool to revolve against the edge or surface
required to be dressed.
And in order that this Invention may be clearly understood I will
proceed to describe the same with reference to the accompanying Sheet
of Drawings, in which Fig. 1 is a front view of the machine; Fig. 2, a
side view; Fig. 3; a plan; and Fig. 4, a longitudinal section through
the carriage supporting the movable platform. The operating parts of
the machine consist of tools to which rotary motion is imparted, some
specimens of which are represented on a larger scale from Fig. 5 to
Fig. 13, inclusive.
A frame a, constructed of wood or other suitable material and
mounted on wheels 6 so that it can be transported easily from one
place to another, carries the mechanism both for supporting and
operating upon the stone or other substance, and is composed of two
main parts held together at the top by transverse bars or stays c,
and supports in suitable bearings d on either side two endless
screws e of a coarse pitch, on which work the screwed bearings f of
a horizontal slide g, carrying the vertical tool holder h. The said tool
holder h consists of a shaft i, supported in bearings, and having at its
lower end the socket or boss k, to which the rotary cutting tools are
fixed, and at its upper end a fly wheel m, while between the bearings j
or on any other suitable part of the shaft is a pinion nor worm
wheel, gearing into other pinions o, or worms receiving rotary motion
from a pulley p, to which power is imparted in any known manner.
The said tool holder is caused to slide on its horizontal bars or

page_text: slides g by means of a worm q and worm wheel actuated by a hand
wheel r or other suitable device, and its vertical motion is imparted by
means of a series of bevil and cog wheels and pinions & placed both on
the said vertical screws e and on a transverse shaft t operated by a hand
wheel or other suitable device. On the lower part of the frame is a
strong platform, having rails w, on which run the wheels supporting
the truck x for holding the stone or other substance. The said truck,
which may be moved backwards and forwards by means of a screw ý or
other suitable means, carries a movable platform z working at one end
on a hinge or pivot a', while the other end may be raised and lowered as
required by means of a lever 6', one end of which works on a screw c¹
operated by hand or otherwise, and the other end presses against the
under side of the said movable platform z, so that the nearer the lower
end of the lever approaches the movable end of the platform the greater
is the angle of the said lever with reference to the screw, and in pro-
portion therewith the upper end of the said lever rises, carrying with it
the movable end of the platform, so that the stone or other substance
placed thereon may receive any inclination in relation to the vertical
shaft carrying the cutting tool. At the other end of the said truck x is
a turntable d' rotated by means of a worm e¹ gearing into teeth placed
around its periphery, so that the stone or other substance may present
any or all of its sides or surfaces to the action of the rotary cutting tool
or tools; and the said turntable may he enclosed in any suitable manner,
so as to preserve the working parts from dust or other injurious matter.
With this improved mechanism all kinds of dressing, moulding, and
polishing can be accomplished with the greatest ease and exactitude,
thus saving much time and manual labour.
Having thus described the nature and particulars of this Invention,
I claim,-
First. The travelling or portable machine capable of being readily
removed from one place to another, as herein described and specified.
Second. The tools for effecting all kinds of moulding, dressing, and
polishing, as illustrated in the accompanying Sheet of Drawings.
Third. Fixing the stone or other substance upon a travelling carriage
having a movable platform and turntable capable of presenting the said
stone or other substance to the cutting tools in an inclined or any other
position.

page_text: Fourth. The means and apparatus for dressing, moulding, and
polishing stone, marble, and other similar substances, as herein
described and illustrated in the accompanying Drawings..
In witness whereof, I; the said Edward Thomas Hughes, have
hereunto set my hand and seal; this Twenty-fifth day of May,
in the year of our Lord 1869.
