ما
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ENOCH
CHAMBERS, of the City of Melbourne, in the Colony of Victoria, Engineer
and Ironfounder, send greeting.
WHEREAS I am desirous of obtaining Royal Letters Patent for securing
unto me Her Majesty's special license that I, my executors, administrators,
and assigns, and such others as I or they shall at any time agree with, and
no others, shall and lawfully may, from time to time, and at all times during
the term of fourteen years (to be computed from the day on which this instru-
ment shall be filed in the Great Seal Patent Office), make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and the Isle of Man, an Invention of "THE USE OF HYDRAULIC POWER
FOR THE BREAKING, CRUSHING, OR PULVERIZING OF QUARTZ, BLUESTONE, OR OTHER
STONE OR MINERAL OF ANY DESCRIPTION, AND THE USE OF A WROUGHT-IRON LEVER
OR JAW IN MACHINES FOR CRUSHING QUARTZ OR ANY OTHER MINERAL, AND THE

page_text: USE OF STEEL TEETH AND STEEL SHIELD PIECES FOR THE LEVERS OR JAWS IN SUCH
MACHINES," and in order to obtain the said Letters Patent I must by an
instrument in writing under my hand and seal particularly describe and
ascertain the nature of the said Invention, and in what manner the same is
to be performed.
NOW KNOW YE, that the nature of the said Invention, and the manner
in which the same may be performed, is particularly described and ascertained
in and by the following statement, that is to say:-
As a means of gaining power, I propose to apply a hydraulic machine, as
shewn in Drawing (Figure 1), with the rams acting direct on a compound
lever or jaw, and to attach to the frame of the machine a cylinder (to be
worked either by steam, water, or other agent,) with the plunger rod of an
hydraulic ram continued as shewn in Drawings of cylinder (Figure 1),
whereby the machine is not incumbered with any revolving shafts or gearing
of any description, and therefore friction is done away with, as also the
expense of gearing and bearings, &c., which always entail much wear and
.tear.

it allows the material
I do not confine myself to any particular mode of fixing the rams, or.
connecting them with the machinery, but the mode shewn in the Drawings
is a practicable mode, and I consider it a good one,
to be broken, crushed, or pulverised to fall of its own gravity from one
point to the other, and then into the receptacle underneath the machine;
neither do I confine myself to two or any other number of rams.
may be so
claim as a
The movable lever or jaw I propose to make of wrought iron, and I claim
as part of my Invention the making it of this material, but it may also be
made of any other material that may be found suitable, and it
made (if required) as to allow angular pieces made of steel (and I
part of my Invention the making them of steel), or of iron with a portion of
steel or of other metal or metals that may be found adapted to fit into it, so
that the angular pieces can at any time be removed for repairs or renewal,
should such be found necessary. The lever or jaw, made and placed as shewn
in Drawing (Figure 1), will allow the larger portions of materials to be taken
in at the top, which, when being crushed, broken, or pulverised, will fall by
their own gravity down to the lower part of the lever or jaw, and it can be
easily seen, by the inspection of the Drawing (Figure 1), that the lever or
jaw acts both ways, that is, both upper and lower portions work backwards
and forwards, and by this means the inconvenient weight required in other
machines is saved.
For the purpose of reducing extra large pieces of materials, I propose to

page_text: make the stationary back plate of the machine of wrought iron, but it may
also be made of any other material that may be found suitable, and it may
be so constructed (if required) as to allow the fitting in of pieces of different
shapes made of steel, or of other metal or metals that may be found adapted,
as shewn in Drawing (Figure 4), so that on the upper portion of the moveable
or compound lever or jaw coarser or larger pieces can be fitted, and smaller
pieces on the lower portion, to suit the materials requiring to be broken or
crushed, according as it is required to break, crush, or pulverise the materials
more or more finely. The space at the bottom of the lever or jaw may be
reduced to a smaller guage by admitting water into the lower water chamber,
and discharging the same quantity from the upper one; this can be accom-
plished by opening the safety valve on the top of the upper chamber, which
will permit the water to run through the waste pipe, and by allowing the
suction pipe of the lower chamber to do its duty, which it will do if the
machine is put into a slow motion. When the space has been sufficiently
reduced the safety valve can be replaced, and the machine set to its proper
work. For the enlargement of the space at the bottom of the lever or jaw
just the reverse operation must be performed. The suction pipes of the
water chambers will serve to keep up a supply of water should there be any
waste through leakage, condensation, or from other causes.
.
Figure 2 in the Drawings shows another method in which a cylinder
worked by steam, water, or other agent may be connected with the hydraulic
ram.
Figure 3 shows how certain other agents may be employed to work the
cylinder.
Figure 4 shows several forms of jaws and back plates to correspond, which
may be used particularly for more finely breaking up or pulverizing the
materials. Teeth may be used when required, but it is in many cases not
necessary to use them; in other cases shield pieces may be used.
Figures 5 and 6 shew cross sections of lever or jaw and back plate
respectively with teeth.
What I claim as my Invention is,-
First, the application of hydraulic power, whether made to act in such a
machine as that described in the Specification and Drawing, or any other
machine in which hydraulic power can be used for the purpose, to the
breaking, crushing, and pulverizing of quartz, bluestone, and other minerals
(including metals) of every description.
And also the use, for the purpose of breaking, crushing, or pulverizing
such minerals as aforesaid, of a machine in which the adoption of steam,

page_text: water, hand power, or other agents by which a machine can be worked.
is combined with the adoption of hydraulic power as a means of gaining.
force.
And also the use of wrought iron for the construction of any such levers or
jaws as aforesaid, or any similar lever or jaw, either simple or compound, to
be used in any machine for the purpose of breaking, crushing, or pulverizing
any such minerals as aforesaid.
And also the use of steel for the construction of teeth and of shield pieces,
to be fitted in or on any such levers or jaws as aforesaid, either single or
compound, and of whatever metal made, to be used for the purposes aforesaid,
or to be fitted in or on such back plate as aforesaid.
I do not, however, bind myself to any particular form or shape of lever or.
jaw, as it can be either straight, angular, half-round, or in two pieces, with
joint in centre, or any other shape or form that may be found better adapted;
neither do I bind myself to corrugated, diamond-pointed, or smooth faces, or
partly smooth, as any shape or face can be used, so as to break or crush the
materials, to suit any particular work, as, for instance, cubing stones for
road, metal, &c., or crushing them into small particles, or for pulverizing for
the extraction of gold or other metals; neither do I bind myself to any
particular mode of fitting or placing the teeth or shield pieces.
In witness whereof, I, the said Enoch Chambers, have hereunto set my
hand and seal, this Twenty-fourth day of August, One thousand eight
hundred and sixty-one.

above-named Enoch Chambers, in
