Year: 1865

page_text: LETTERS PATENT to George Henry Goodman, of the London Road, in the
County of Surrey, Engineer, and Edward Bow, of Maidstone, in the
County of Kent, Artificial Stone Manufacturer, for the Invention of
"IMPROVEMENTS IN MACHINERY FOR CRUSHING OR REDUCING STONE, QUARTZ,
AND CRUED MINERAL SUBSTANCES"
Sealed the 8th May 1866, and dated the 13th November 1865.
PROVISIONAL SPECIFICATION left by the said George Henry Goodman
and Edward Bow at the Office of the Commissioners of Patents,
with their Petition, on the 13th November 1865.
We, GEORGE HENRY GOODMAN, of the London Road, in the County of
Surrey, Engineer, and EDWARD Bow, of Maidstone, in the County of Kent,
Artificial Stone Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR CRUSHING OR REDUCING STONE,
QUARTZ, EMERY, AND OTHER MINERAL SUBSTANCES," to be as follows:-
Our Invention consists in the employment of machinery for crushing stones,
quartz, emery, and other mineral substances as follows:-We mount loosely
upon axles and opposite to one another blocks or lumps of metal, the surface
or surfaces of which at one part meet or nearly meet, the distance being
regulated according to the size to which it is desired to reduce the quartz or

page_text: other material. The jaws of these blocks radiate from the points at which
they nearly meet, and somewhat assume the form of a letter ), being curved
or rather rounded at the parts where the two surfaces nearest approach each
other. The space between the upper surfaces forms a sort of hopper for the
reception of the material to be crushed, and the space between the lower
allows the material to escape freely to the ground or suitable receptacle
provided for the same; or in some cases we place below the lumps or blocks
rollers to receive the material after being crushed by the lumps; the crushed
material then passes between the rollers and becomes further reduced. The
distance the rollers are apart is regulated according to the degree of fineness
to which the material is to be reduced. The blocks are formed with arms or
tails extending in contrary directions below the outer ends, of which we mount
excentric cranked shafts on which the arms of the blocks rest. The same shafts
carry toothed wheels in gear with one another, which are also in gear with
pinions, the shafts of which carry fast and loose pulleys, and round which
We do not,
straps pass for communicating motion from any prime mover.
however, confine ourselves to the employment of driving pulleys on each shaft,
as in some cases one set will be sufficient. Sometimes we insert in the
working face or faces of the blocks metal teeth, made by preference of steel
or chilled iron, in order to facilitate the crushing action. The whole machine
may be mounted on wheels to render it portable, and in some cases we attach
a steam engine to the frame for driving the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Henry Goodman and Edward Bow in the Great
Seal Patent Office on the 12th May 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HENRY GOODMAN, of the London Road, in the County of Surrey, Engineer,
and EDWARD Bow, of Maidstone, in the County of Kent, Artificial Stone
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Henry Goodman and Edward Bow, Her special licence
that we, the said George Henry Goodman and Edward Bow, our executors,
administrators, and assigns, or such others as we, the said George Henry

page_text: Goodman and Edward Bow, our 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
5 Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN MACHINERY FOR CRUSHING OR REDUCING STONE, QUARTZ,
EMERY, AND OTHER MINERAL SUBSTANCES," upon the condition (amongst others)
that we, the said George Henry Goodman and Edward Bow, our or one of our
executors or administrators, by an instrument in writing under our, or their,
or one of their bands 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 we, the said George Henry Goodman and
Edward Bow, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, reference being had
to the accompanying Drawings, that is to say:-
Our Invention consists in the employment of machinery for crushing
stone, quartz, emery, and other mineral substances, as follows:-We mount
loosely upon axles and opposite to one another blocks or lumps of metal, the
surface or surfaces of which at one part meet or nearly meet, the distance
being regulated according to the size to which it is desired to reduce the
quartz or other material. The jaws of these blocks radiate from the points at
which they nearly meet, and somewhat assume the form of a letter )(, being
curved or rather rounded at the parts where the two surfaces nearest approach
each other. The space between the upper surfaces forms a sort of hopper for
the reception of the material to be crushed, and the space between the lower
allows the material to escape freely to the ground or suitable receptacle
provided for the same; or in some cases we place below the lumps or blocks
rollers to receive the material after being crushed by the lumps; the crushed
material then passes between the rollers and becomes further reduced. Some-
times we place a seive below the rollers, or we use a seive instead of the
rollers. The distance the rollers are apart is regulated according to the
degree of fineness to which the material is to be reduced. The blocks are
formed with arms or tails extending in contrary directions, below the outer
ends of which we mount excentric cranked shafts on which the. arms of the
.L

page_text: blocks rest. The same shafts carry toothed wheels in gear with one another,
which are also in gear with pinions, the shafts of which carry fast and loose
pulleys, and round which straps pass for communicating motion from any
prime mover. We do not, however, confine ourselves to the employment of
driving pulleys on each shaft, as in some cases one set will be sufficient.
Sometimes we insert in the working face or faces of the blocks metal_teeth,
made by preference of steel or chilled iron, in order to facilitate the
crushing action. The whole machine may be mounted on wheels to render
it portable, and in some cases we attach a steam engine to the frame for
driving the machine.
The accompanying Drawings illustrate how the Invention may be carried
into effect.
Figure 1 is a view in side elevation of a machine constructed according to
our Invention; Figure 2 is a side view on a larger scale of the blocks or
lumps; Figure 3 is a detached view of one of the shafts carrying the
eccentric cranks, showing the tail of one of the jaws and the bearing on
which it slides; Figure 4 is a vertical section of the chief parts of the
machine taken between the lumps or blocks. Similar letters of reference
refer to like parts in all the Figures.
a, a, are the lumps or blocks of metal mounted on axles or shafts b, b.
The faces of these blocks are by preference fitted with teeth, as shown most
clearly at Figure 2, but we do not limit ourselves to the use of teeth, as
for many purposes a plain surface is sufficient. The lumps or blocks are
mounted loosely on the axles b, b, which rest in bearings formed in fulcrum
blocks supported in the frame c of the machine, so that these axles form a
fulcrum about which the said blocks are free to move. The tails d, d, of
these blocks a, a, rest at their outer ends on bearings e, e, which are them-
selves supported by shafts f, f, free to revolve in bearings in the frame c
of the machine, and to slide in grooves under the tails of the jaws. These
shafts ff, carry eccentric cranks 9, 9, as in Figure 3, or eccentrics as in
Figure 2, set beneath the tails d, d, of the blocks; thus at every revolution
of the shafts f, f, the tails d, d, are raised and lowered, and a corresponding
oscillating motion is thus communicated to the jaws formed by the lumps a, a.
The shafts f, f, carry toothed wheels h, h, in gear with one another, whereby
motion is communicated to both shafts at one and the same time and at
equal speed; one of these wheels h is in gear with a pinion i on a shaft k,
carrying a pulley o, round which a strap passes from any prime mover; lis
fly wheel for regulating the motion; m is a hopper for receiving the material
to be crushed.

page_text: And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim the employ-
ment in machines for crushing or reducing stone, quartz, emery, and other
mineral substances of lumps or blocks of metal, between which the material
to be crushed is passed, the said blocks being constructed and caused to work
substantially in the manner herein-before described and illustrated in the
accompanying Drawings.
In witness whereof, we, the said George Henry Goodman and Edward
Bow, have hereunto set our hands and seals, this Tenth day of May,
in the year of our Lord One thousand eight hundred and sixty-six.
GEORGE HENRY GOODMAN. (L.S.)
EDWARD BOW.
