Year: 1857

page_text: LETTERS PATENT to Isidore Charles Clöet, of Ghent, in the Kingdom of
Belgium, and of the Office for Patents, 77, Chancery Lane, in the
County of Middlesex, Engineer, for the Invention of "AN IMPROVED
RICE AND BARLEY MILL."
PROVISIONAL SPECIFICATION left by the said Isidore Charles Clöet at
the Office of the Commissioners of Patents, with his Petition, on the
30th June 1857.
I, ISIDORE CHARLES CLOET, of Ghent, in the Kingdom of Belgium, and of
the Oflice for Patents, 77, Chancery Lane, in the County of Middlesex,
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVED
RICE AND BARLEY MILL," to be as follows (that is to say) :-
My Invention, which has reference to a mill for cleaning or removing the
husk from rice or barley, consists in enclosing within a case or jacket a circular
stone, mounted (through the medium of a shaft and bearings) so as to revolve
in opposite directions and admit of the rice or barley being carried round and
worked between the periphery of the stone and case, by steam or otherwise,
the said rice or barley during the rotatory action of the apparatus being uni-
formly fed and discharged without personal attendance as at present, by means
of suitable valves or openings in connection with tooth and pinion gearing,
whereby the valves are actuated and regulated as required during the operation
of the apparatus.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Isidore Charles Clöet in the Great Seal Patent Office on
the 30th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISIDORE
CHARLES CLOET, of Ghent, in the Kingdom of Belgium, and of the Office
for Patents, 77, Chancery Lane, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of June, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her beirs and successors, give and grant unto me,
the said Isidore Charles Clöet, Her special licence that I, the said Isidore
Charles Clöct, my executors, administrators, and assigns, or such others
as I, the said Isidore Charles Clöet, 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 "AN IMPROVED RICE AND BARLEY MILL," upon the condition
(amongst others) that I, the said Isidore Charles Clöet, my exccutors 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
nionths next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Isidore Charles Clöct, do hereby
declare the nature of my said Invention, and in what manner the sanie is
to be performed, to be particularly described and ascertained in and by the
following statement and the Drawings therein referred to (that is to say):-
My Invention, which has reference to a mill for cleaning or removing the
husk from rice or barley, consists in enclosing within a case or jacket a circular
stone, mounted (through the medium of a shaft and bearings) so as to revolve
in opposite directions, and admit of the rice or barley being carried round and
worked between them by steam or otherwise, the said rice or barley during
the rotatory action of the apparatus being uniformly fed and discharged, without
personal attendance as at present, by means of suitable valves or openings in
connection with tooth and pinion gearing, whereby the valves are actuated and
regulated as required during the operation of the apparatus.

page_text: But in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say):
Fig. 1 represents a sectional side elevation of my improved rice and barley
mill, showing the passage through which the apparatus is supplied from the
hopper; Fig. 2, a transverse vertical section taken through the dotted line in
Fig. 1; Fig. 3, a side view of the apparatus complete; and Fig. 4, a top or
plan view of the same. In each Figure the same letters of reference denote
similar corresponding parts.
A, A, the millstone; B, B, cylindrical case or jacket; C, C, intervening
space or passage in which the rice is operated upon during the rotatory
action of the apparatus; D, D, millstone shaft; E, E, plumber block bear-
ings, in which the said shaft revolves; F, F, standard side frames; G, G,
transverse tie rods for connecting the same; H, HI, longitudinal bearing stays
attached thereto; I, I, plumber block bearings, in which the trunnions J, J,
of the case or jacket revolve; K, K, driving rigger keyed upon the shaft, for
giving motion to the same through the medium of steam machinery or
other motive power; L, L, strap wheel firmly keyed to the trunnions, for
giving motion to the case or jacket in a contrary direction to the stone;
M, M, self-supplying and feeding hopper, for communicating through the
intervention of the hollow trunnions to the space between the case and
stone; N,N, valve for supplying the hopper; 0, 0, valve for regulating the
supply of the rice or otherwise to be operated upon; P, P, fixed hollow tube
or trunk in connection with the hopper, by which the grain is convoyed
through the trunnions; Q, Q, fixed bracket, for supporting the same by means
of nuts and bolts R, R; S, S, the rice or barley; T, T, intermediate pulley
keyed upon the shaft, for giving motion to the coupling wheel T¹ through the
medium of the strap T2, so as to actuate the hopper valves through the inter-
vention of the multiplying wheels U, V, W, X, Y, and Z, and cam action Z',
in gear with the valve levers a, a, as represented, by which the requisite
alternating movement of the valves is obtained; b, b, discharge valve, worked
by means of a cam c, c, lever d, d, and link-slot motion e, e, motion being com-
municated to the same by means of the train of wheels f, g, h, i, j, and k,
5 which revolve in a stud plate or crown bearing 1, 7, in connection with the casc
or jacket; m, m, concentric slot bearings, in which different sized pinions may
be made to revolve, and changed as required, for the purpose of regulating the
time the rice or barley is under operation, by altering the speed of the cams;
,, tube or spout, for supplying the hopper from a loft or otherwise; o, o,

page_text: hand wheel and slide, for regulating the descent of the grain proportionately
to the required supply.
With reference to the action of the apparatus, it may be necessary to
observe, that on the valve N being opened a quantity of rice regulated by the
hand wheel and slide o, proportionately to the quality desired, is supplied to
the hopper and carried through the hollow trunnions (on the valve O being
opened) to the space between the stone and jacket to be operated upon; the
said rice being discharged through the valve or slide opening 6 by the action of
the cam c, lover d, and link-slot motion e, upon the said valve being brought
to the lower portion of the apparatus by the slow rotatory movement of the
case or jacket.
b
In conclusion to the foregoing description I would here briefly note, that
the driving strap for communicating motion to the case or jacket may run on
the periphery thereof, instead of on the strap wheel, as represented at L, L,
and that any suitable multiplying apparatus, placed and worked in any con-
venient manner by steam machinery or other motive power, may be employed
for the purpose of actuating the feed and discharge valves; and I would
further note, that rice dressed by my improved mill is less liable to be broken
or injured than by those at present in use, whereby the commercial value
thereof is greatly increased, and that a considerable saving of time is effected
in dressing rice or barley compared with the means hitherto employed for the
same purposc.
Having now fully described the nature of this my said Invention, and the
manner in which the same is to be performed, I would have it clearly under-
stood that I do not intend to confine myself to the precise details herein-before
described, as the same may be varied without departing from the general
principle of these my said improvements; but that which I do claim as new
and of my said Invention is, the employment of self-acting feed and discharge
valves actuated through the medium of multiplying gear in connection with
the revolving millstone and case, in the manner and for the purposes hercin-
before set forth and described.
In witness whereof, I, the said Isidore Charles Clöct, have hereunto set
my hand and seal, this Twenty-third day of December, in the year of
our Lord One thousand eight hundred and fifty-seven.
ISIDORE CHARLES CLOET, Ingr. (L.S.)
