page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVEMENTS IN DISINTEGRATING AND PULVERIZING
MACHINERY."-A communication from abroad by Jerome Josiah
Webster, of Magog, St. Francis, Trader, and John H. Hall, of
Montreal, Gentleman, both in Canada.
Sealed the 7th June 1872, and dated the 11th December 1871.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 11th December 1871.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN DISINTEGRATING AND
PULVERIZING MACHINERY," a communication, to be as follows:-
C
:―
ants in machines used for

page_text: stones, quartz, and other mineral products, and manufactured articles
requiring to be levigated for market, such as litharge, colours, and other
chemical compounds, and reducing to flour any of the various grains
for the purpose of producing a simpler and cheaper machine than those
at present employed, and at the same time one capable of doing the
work equally well or in a superior manner.
The framework of the machine is of any ordinary and suitable con-
struction, and is erected on a strong bed. On the upper rails of the frame-
work are situated two plummer blocks, secured to or made in one with it.
In the space existing between the two sides of the framework a casing is
situated, consisting of two dises with a short cylinder interposed between
them. In the centre of the discs a hole is bored for the shaft. The
edges of the cylinder are made parallel, so that when they are together
the faces of the aforesaid discs may also be parallel. The whole casing
is then placed concentrically with the centre line of the two plummer
blocks and at a right angle horizontally and vertically with it, equally
distant from both plummer blocks, with the bottom edges resting upon
the bed, and the whole being held in place by a strap secured to the
frame by bolts. The aforesaid cylinder and discs are secured together,
or if preferred the cylinder may be made in a piece with one of the
discs. The shaft is extended to one end through the plummer block,
and on this extension is placed the driving pulley or a suitable gear
wheel. On the part of the shaft within the casing, or between the
ends of the cylinder, is placed and secured a wheel which is not a true
circle, but on its periphery has tangential ares with their ends terminated
in superficies to act as hammers; these superficies are extended beyond
the thickness of the wheel by attaching supplementary pieces thereto,
but I prefer to form them in one piece with the wheel; thus if the
wheel be made of wrought iron or steel the projections may be ".
"jumped "
on, if of cast iron they can be moulded in the sand and run in one
piece at the time of casting the wheel. In the aforesaid discs openings are
made for the introduction of feed pipes for conveying the material to be
acted upon by the machine, and depositing it upon the hub of the afore-
said peculiarly formed revolving wheel.
In addition to the supplementary pieces above described others of a
similar character may be added on the sides of the said wheel; these
if used will be so situated that they pass round when revolving in a
circle just without the opening of the converging pipes through the discs.

page_text: The faces of these projections as well as of those first mentioned are
radial to the centre of the shaft.
If desired on the inside of the discs other projections may be attached
or made in one with them. These are of a similar character to those
above described, and are so situated that as the wheel revolves the
projections first mentioned will revolve without them while the second
projections revolve within them; a suitable amount of clearance must be
allowed in each case. The faces of these projections will be set at an
angle, so that particles struck by some of the projections and striking
against others will diverge at a proper angle.
In some cases I prefer to corrugate the inner surfaces of the discs.
Discharge pipes are provided, whose number and size may be varied
as required. A shield is placed over the inner end of these discharge
pipes for the purpose of preventing the passage of large pieces of
material.
When used for grain the shield may be made of gauze. A door is
arranged to permit an examination of the inside without taking the
machine apart.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 10th June 1872.
о
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Robert Lake, Her special licence
that I, the said William Robert Lake, my executors, administrators,
and assigns, or such others as I, the said William Robert Lake, 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

page_text: 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 DISINTEGRATING AND PULVERIZING MACHINERY," a communication to me from
abroad by Jerome Josiah Webster, of Magog, St. Francis, Trader, and John 5
H. Hall, of Montreal, Gentleman, both in Canada, upon the condition
(amongst others) that I, the said William Robert Lake, 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 1
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 William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same 1
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification:-
This Invention has reference to improvements in machines used for
disintegrating or reducing to powder various substances, such as earths, 2
stones, quartz, and other natural products and manufactured articles
requiring to be levigated for market, such as litharge, colours, and other
chemical compounds, and reducing to flour any of the various grains for
the purpose of producing a simpler and cheaper machine than those at
present employed, and at the same time one capable of doing the work 2
equally well or in a superior manner.
Figure 1 is a side elevation of one of the said improved machines;
Figure 2 is a longitudinal vertical section; Figure 3 an end elevation,
and Figure 4 a transverse section of the said machine; Figures 5, 6, 7,
and 8 show detached portions of the same. Like letters indicate tho
samo parts throughout the Drawing.

The framework a of the machine is of any ordinary and suitablo
construction, it may be of wood or iron; b is the bed on which the
framework a is raised. On the upper rails of the said framework aro 3
situated two plummer blocks c of any ordinary construction, secured to

page_text: or made in one with it. In the space existing between the two sides of
the framework a a casing.is situated, consisting of two dises & with a
short cylinder e interposed between them. In the centre of the discs
a hole is bored for the shaft f. The edges of the said cylinder e are made
parallel, so that when they are together the faces of the aforesaid discs d
may also be parallel. The whole casing is then placed concentrically
with the centre line of the two plummer blocks c and at right angles
horizontally and vertically with it; it is equally distant from both
plummer blocks, with the bottom edges resting upon or in the bed b, the
whole being held in place by a strap 7 secured to the frame by suitable
bolts. The aforesaid cylinder e and discs d are secured together in the
ordinary manner, or if preferred the cylinder may be made in one with
one of the discs. The shaft f is extended to one end through the
plummer block, and on this extension is placed the driving pulley h
on a suitable gear wheel. On the part of tho shaft within the casing or
between the ends d of the cylinder is placed and secured a wheel i of
the configuration shewn in Figures 2 and 4. The said wheel is not
a true circle but on its periphery has tangential arcs with their ends
terminated in superficies h³ to act as hammers. These superficies may
be extended laterally beyond the wheel i by attaching supplementary
pieces thereto, but I prefer to form them in one piece with the wheel.
Thus if the wheel is made of wrought iron or steel the projections /
may be "jumped" on, if of cast iron they can be moulded in the sand
and cast on the said wheel. In the aforesaid discs d openings are made
for the introduction of feed pipes for conveying the material to be
acted upon by the machine, and depositing it upon the hub of the
revolving wheel i.
In addition to the supplementary picces k above described others of a
similar character may be added to the sides of the wheel i; they will be
situated as shewn at m, so that they pass round when revolving in a
circle outside the opening of the pipes through the discs. The faces
of these projections as well as those of the pieces are radial to the
centre of the shaft f.
i
Furthermore on the inside of the discs d projections n may be attached
or made in one with them. These projections are of a similar character
to the pieces l, m, and are so situated that as the wheel i revolves tho
pieces will revolve outside of them, while the pieces m revolve within
them; in each case a suitable clearance must be allowed. The faces of

page_text: me by my foreign correspondents, and the manner of performing the
same, I wish it understood that I claim,―
First. The novel combination of the frame a, bed b, plummer blocks c,
discs d, cylinder e, shaft f, strap 9, pulley h, superficies ', wheel,
supplements /, fced pipes 2, discharge pipes o, and door'p, with or without
the projections m and n, all working together in the manner and for the
purpose described.
Second. The novel combination of the discs d, cylinder e, shaft f
wheel i, superficies ', supplements k, pipes and o, with or without the
projections m and n, all working together and with other parts of the
machine as and for the purpose described.

In witness whereof, I, the said William Robert Lake, have hereunto
my hand and seal, this Eighth day of June, in the year of our
Lord One thousand eight hundred and seventy-two.
