AN IMPROVED HORSE MILL OR GEAR
Year: 1858

page_text: LETTERS PATENT to Joseph Constant Boisneau, of Chatellerault, in the
French Empire, Engineer, for the Invention of "AN IMPROVED HORSE
MILL OR GEAR."
Sealed the 12th May 1859, and dated the 16th November 1858.
PROVISIONAL SPECIFICATION left by the said Joseph Constant Boisneau
at the Office of the Commissioners of Patents, with his Petition, on the
16th November 1858.
I, JOSEPH CONSTANT BOISNEAU, of Chatellerault, in the French Empire,
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED HORSE MILL OR GEAR," to be as follows:-
In this mill or gear the power of the horse or other animal is applied to
cause the rotation of a driving wheel or drum fitted at the end of a shaft
round the wheelwork of the machine. The wheel being fixed on the shaft
causes the rotation thereof, as also that of a vertical bevel wheel, which in
turn gears into and drives a horizontal bevelled pinion formed or fitted on the
crown of a large mitre wheel, the teeth of which are inverted, and drive a
vertical pinion on the shaft from which the power is to be taken or applied.
By proportioning the various wheels in the train to the speed required, any
desired number of revolutions can be communicated to this latter shaft. In.
some cases the main driving wheel may be toothed, and made to run in a
circular rack.

page_text: In order to insure the grip of the driving wheel, the end of the beam which
carries the driving wheel shaft may be weighted, and a fly wheel will in some
cases be advantageous on the driving wheel shaft.
Although I have only described one main driving wheel and
SPECIFICATION in pursuance of the conditions of the Letters Patent, file
by the said Joseph Constant Boisneau in the Great Seal Patent Offic
on the 16th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
CONSTANT BOISNEAU, of Chatellerault, in the French Empire, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Iler reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Joseph Constant Boisneau, IIer special licence that I, the
said Joseph Constant Boisneau, my executors, administrators, and assigns, or
such others as I, the said Joseph Constant Boisneau, my executors, adminis
trators, 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 "AN IMPROVED HORSE MILL OR GEAR," upon the condition
(amongst others) that I, the said Joseph Constant Boisneau, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should 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 Joseph Constant Boisneau, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
ollowing statement thereof, reference being had to the Drawings hereunto
nnexed, that is to say:-
In this mill or gear the power of the horse or other animal is applied to

page_text: cause the rotation of a driving wheel or drum fitted at the end of a shaft
round the wheelwork of the machine. The wheel being fixed on the shaft
causes the rotation thereof, as also that of a vertical bevil wheel which in
turn gears into and drives a horizontal bevilled pinion formed or fitted on the
crown of a large mitre wheel, the teeth of which are inverted, and drive a
vertical pinion on the shaft from which the power is to be taken or applied.
By proportioning the various wheels in the train to the speed required, any
desired number of revolutions can be communicated to this latter shaft. In
some cases the main driving wheel may be toothed, and made to run in a
circular rack.
In order to insure the grip of the driving wheel, the end of the beam which
carries the driving wheel shaft may be weighted, and a fly wheel will in some
cases be advantageous on the driving wheel shaft.
Although I have only described one main driving wheel and shaft, two or
more may be employed to set the same train of wheels in motion.
Figure 1 of the accompanying Drawings is a view in side elevation, and
Figure 2 a plan of a horse mill or gear constructed according to my Invention.
6 is a wheel or drum on the shaft c, which has rotary motion communicated to
it through a horse or other animal being harnessed to the whipple-tree a.
The shaft is held by supports d fixed to a lever or arm e, and to which the
whipple-tree is hooked. The shaft c has keyed on it, at the opposite extremity
to that of the wheel or drum b, a toothed wheel f, which transmits motion to a
pinion g fixed on a vertical shaft h, held in any suitable manner in a frame of
wood or metal i, and turning at its lower part in a socket joint. On the vertical
shaft ha toothed wheel k is keyed of a larger diameter than the pinion g, and
this wheel communicates motion to a pinion on the shaft m, which gives the
required rotary motion to any apparatus that may be attached to it. This
shaft m is composed of several parts jointed together, and carries a pulley (not
shewn in the Drawing), the diameter of which can be regulated according to
the circumstances, as also that of the wheel 6 according to the speed at which
the
gear is required to move. For two or more horses to work the apparatus I
joint the lever or arm e at p, and connect it to the vertical shaft h by arms q, q,
which are prolonged to receive a second arm shown in red ink lines. If the
gearing is to be a fixture, I form a brickwork or masonry bed, on which a
rack is placed, as indicated in red lines x. In this case the wheel 6 must be
replaced by the pinion 6', shewn in red lines; s is a plate or platform for
loading or weighting the gear as circumstances may require. I sometimes
employ a fly wheel on the shaft c to regulate the motion, as indicated by the
red lines z.

page_text: And having now described the nature of my said Invention, and in what
manner the same is to be performed; I declare that I claim the improved
horse mill or gear herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said Joseph Constant Boisneau, have hereunto
set my hand and seal, this Twelfth day of May, One thousand eight
hundred and fifty-nine.
