COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville

and Declaration, on the 10th September 1873, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,

page_text: Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the
County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "A NEW AND
IMPROVED REGULATOR OR GOVERNOR FOR ADJUSTING THE SPEED OR ROTARY MOTION
OF STEAM ENGINES," communicated to me by Ernst Schenck, Baronet,
and Wilhelm Maurer, two persons resident at Vienna, Austria, Admini-
strators of the Firm Dampfmaschinen, Regulator, Fabrick, Friedrich,
and Co., Vienna, and have petitioned Her Majesty grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and made solemn Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and
seal fully describes and ascertains the nature of the Invention, and
the manner in which the same is to be performed, reference being had
to the accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
This Invention consists in the direct action of the governor upon
the expansion, as well as in the principles of its arrangement in
general.
The fundamental principles of its construction will be found in the
particular and new application of an eccentric, which regulates its
stroke and the degrees of the angle of its action by the governor in
such a manner that at the highest expansion o, o, 1, a prolongation and
advancing of the stroke of the expansion valve takes place, whilst at
greater feeding (to 1, o) the contrary will be produced. The governor
may be mounted horizontally or vertically upon the flywheel shaft,
so that the number of revolutions of the governor corresponds to those
of the steam engine.
This Invention is illustrated in the accompanying Drawings, in which
Fig. I. represents the new and improved regulator connected with the
distributing slide valve, and Fig. II. is a sectional view of the same
by the line A, B, Fig. I.
The
Fig. I. shows the governor in its lowest position to the shaft.
plate F has two pins, on which the bolt eyes L serve as rotating centres
to the lenses. The lenses fare provided with a boss, upon which the

page_text: drawing rods K are pivoted. The said rods K are connected to the hard
brass piece G by arms pivoted on them, so that the said piece G moves
freely in its bearing by means of the motion of the plate F. If by the
action of the centrifugal force the lenses fly out the piece G is displaced
in its bearing conformabily with the angle of elevation of the lenses.
The piece G is provided with a pin or an eccentric g connected to the
valve rod, and changes its stroke at the least difference in the number
of revolutions; I are springs, which replace the flying out lenses to
their normal position. By more or less strain of these springs the
engine will move more or less rapidily.
To make the said Invention better understood a sketch of the
distributing slide valve is represented in the annexed Drawings. This
position shows that the distributing slide valve eccentric is cast together
with the governor, an arrangement which proves to be the cheapest,
the most solid, and therefore the most practical, which however does
not prevent the governor from being mounted separately from the
distributing slive valve eccentric.
Having thus described the nature of the said Invention, and the
manner of carrying it into effect, what I claim and desire to secure by
the said Royal Letters Patent is, the particular and new application of
an eccentric which regulates its stroke and the degrees of the angle
of its action by the governor of the steam engine in such a manner
that at the highest expansion a prolongation and advancing of the
stroke of the expansion valve takes place, whilst at greater feeding the
contrary will be produced, substantially as above described, and
represented in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereto
set my hand and seal, this Sixth day of September, in the year
of our Lord One thousand height hundred and seventy-three.
H. BONNEVILLE. (L.S.)
