Patent Offices, 8, Rue de la Chaussée d'Antin, Paris, France, and 90, Cannon
Street, in the City of London, Patent Agent, for an Invention of "A NEW
OR IMPROVED MACHINE FOR CUTTING AND BORING THE EARTH FOR MINING
PURPOSES." A cominunication from Guillaume Dubois, of Maubeuge. Belgium.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville.at
the Office of the Commissioners of Patents on the 17th March 1882.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 8, Rue
de la Chaussée d'Antin, Paris, France, and 90, Cannon Street, in the City of
London. "A NEW OR IMPROVED MACHINE FOR CUTTING AND BORING THE EARTH
FOR MINING PURPOSES." A communication by Guillaume Dubois, of Maubeuge,
Belgium, Colliery Manager, and Joseph François, of Seraing, Belgium, Builder.
The Invention relates to bringing down coal in mines and to the boring galleries
of rock or other material without blasting, and consists of a machine by which
grooves or cuts may be made to any depth, and holes of large diameter drilled to
the same depth, the said machine being easily modified in such manner that the
drilling and cutting apparatus may be transformed into a mechanical hammer for
striking wedges consisting of three parts, that is to say, two fish plates and the
wedge so called introduced into the holes thus drilled so as to bring down the
mass of earth.
The said machine
represented in the accompanying Drawings, in which Fig. 1
is a longitudinal elevation; Fig. 2, a top plan view; Fig. 3, a section through the
axis; Fig. 4, a front view of the fore part; and Figs. 5, 6, 7, 8 & 9 views of
boring and other tools.
The same letters of reference indicate corresponding parts in the different
Figures.

page_text: A is the cutting or drilling apparatus; B, bars supporting the said apparatus;
C, pivot of bearing bars; D, counter-weights for steadying the apparatus; E,
support of the pivot C; F, frame with iron rod supporting the machine; G, back
driving wheels; H, fore part consisting of four linked wheels allowing the machine
to move in curves of a small radius; J, back adjusting screw; K, cross piece
binding the fore part; L, adjusting screw which, acting in combination with the
endless screws M and N, acting upon the segments O and P, enable the machine to
be brought rapidly into any required [position for cutting and drilling the holes ;
S, fish plates to be introduced in the holes drilled for the purpose, and between
which is placed the wedge T upon which the apparatus transformed into a
mechanical hammer strikes in order to bring down the coal or rock; U, U, hammer
head to be fixed upon the perforator to force the wedge T; Z, cutting tool; Y, tool
drilling holes for wedge T.
Having thus described the said Invention and the manner of carrying the same
into effect, I would have it understood that I do not confine myself to the precise
details above enumerated, as these may obviously be modified without departing
from the Invention, but what I claim and desire to secure by the said Royal
Letters Patent is the combination of the different parts of the machine constructed
and arranged, substantially as above described and represented in the different
Figures of the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereto set
my hand and seal, this Sixteenth day of March, in the year of our Lord
One thousand eight hundred and eighty two.
