This Invention has for its object improvements in machinery for
breaking stone and ore, part of which improvements are applicable to
hammers and pile-driving machines and other machines in which
weights have to be raised and suddenly dropped.
The stamp or hammer or other weight to be operated on is arranged
so that it can rise and fall in guides, and it receives its motion from an
axis having upon it a friction wheel or pulley having by preference a
V form groove in its periphery. It revolves in contact with the stem of
the stamp or hammer or weight, which is of such a form as to fit into
the groove in the pulley. The frictional contact between the stem and
.the pulley causes the stamp or hammer or weight to be lifted. At
intervals apart in the circumference of the friction pulley are notches or
recesses, and when such a notch or recess comes opposite to the stem
immediately the stamp or, hammer or weight falls upon the stone or
ore or other substance placed beneath it and on which it is required to

varied and sometimes there may be but one. In place of grooving the
pulley a groove or grooves may be formed in the stem of the stamp,

act.
It is a peculiarity of this arrangement that the distance the stamp
hammer or weight is lifted is constant, and is the same whatever the
position it occupies when the lift commences.
For the purpose of breaking stone and ore I arrange a number of
stamps to work side by side, and under them is a girder supporting
beneath each stamp a bed of steel or chilled cast iron or other material.
The bed is formed with longitudinal and transverse ridges or edges
which serve to cleave the stone or ore and leave it free to fall away
when so broken. These cutting beds are keyed firmly to the supporting
girder. The material when broken falls away on both sides of the bed
on to a riddle underneath the girder. The face of the stamp may be
made of a form similar to that of the bed.

MACHINERY FOR BREAKING STONE AND ORE, PART OF WHICH IMPROVEMENTS ARE
APPLICABLE TO HAMMERS AND PILE-DRIVING MACHINES AND OTHER MACHINES IN
WHICH WEIGHTS HAVE TO BE RAISED AND SUDDENLY DROPPED," upon the
condition (amongst others) that we, the said Thomas Bevington, Sydney
Courtauld, and John Andrew Norberg, our executors or administrators,
by an instrument in writing under our or their hands and seals, or
under the hand and seal of one of us or them, 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 Sydney Courtauld, on behalf of
myself and the said Thomas Bevington and John Andrew Norberg,
do hereby declare the nature of the said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say:-
This Invention has for its object improvements in machinery for
breaking stone and ore, part of which improvements are applicable to
hammers and pile-driving machines, and other machines in which weights
have to be raised and suddenly dropped.
The stamp or hammer or other weight to be operated on is arranged
so that it can rise and fall in guides, and it receives its motion from an
axis having upon it a friction wheel or pulley having by preference a
V form groove in its periphery. It revolves in contact with the stem.
of the stamp or hammer or weight, which is of such a form as to fit into
the groove in the pulley. The frictional contact between the stem and
the pulley causes the stamp or hammer or weight to be lifted. At
intervals apart in the circumference of the friction pulley are notches
or recesses, and when such a notch or recess comes opposite to the stem
immediately the stamp or hammer or weight falls upon the stone or ore
or other substance placed beneath it and on which it is required to act.
The number of notches or recesses in the friction pulley may be varied
and sometimes there may be but one. In place of grooving the pulley a
groove or grooves may be formed in the stem of the stamp, hammer, or
weight and pulley adapted thereto.
It is a peculiarity of this arrangement that the distance the stamp
hammer or weight is lifted is constant, and is the same whatever the
position it occupies when the lift commences.
For the purpose of breaking stone and ore I arrange a number of
stamps to work side by side, and under them is a girder supporting
beneath each stamp a bed of steel or chilled cast iron or other
material. The bed is formed with longitudinal and transverse ridges or
edges, which serve to cleave the stone or ore and leave it free to fall
away when so broken.
These cutting beds are keyed firmly to the
standards and supporting guides of the machine. The material when
broken falls away on both sides of the bed on to a riddle underneath
the girder. The face of the stamp may be made of a form similar to
that of the bed.
In order that our said Invention may be most fully understood and
readily carried into effect, we will proceed to describe the Drawings
bereunto annexed.

page_text: Figure 1 is a vertical section of apparatus constructed according to
our Invention for breaking stones or minerals. a is one of the end
standards of the machine; b and c are horizontal bearers connecting it
with the standard on the other side of the machine; and d is a cap
piece also extending from one standard to the other; e is one of a
number of stamps with which the machine is provided; it is capable of
rising and falling in guides. f, f¹, are portions of one pair of guides; in
this Figure the guides are not fully shown. is one of the notched or
recessed friction wheels or pulleys; in this arrangement one notch or
recess only is shown. The axis h of the pulleys g is carried in bearings
on the standards a, a, and it has a spur wheel upon it gearing with a
pinion on the axis i, similarly mounted and carrying a belt pulley to
receive the driving strap and a fly wheel. is a friction wheel bearing
against the back of the stamp e (there is one for each stamp), and
keeping it against the pulley g (except where it is cut away) with
sufficient pressure to enable the pulley in its rotation to lift the stamp.
'The friction wheel is carried in a casting ¹, which is fitted so as to
be able to slide horizontally between the guides f, and is set up to give
the pressure required on the back of the stamp by a wedge k³ acting ou
another wedge 3 clipping the casting at the back. k4 is a screw
with a hand wheel upon it for adjusting the wedge ; this screw is
carried by a bridge piece extending from one guide f to the next. The
stamps e are of wrought iron; they have keyed to them at their lower
ends heads c¹ of cast iron chilled on the working faces.
At their upper
ends the stamps are continued through the cap piece d, and are provided
with vulcanized india-rubber buffer springs e to check their descent
and prevent them falling dead on to the bed or anvil at m. The bottom
plate of the spring descends on to a plank of timber fixed on the top
of the cap piece d; n is a table on which the stone or material to be
broken is fed and pushed down on to the bed or anvil. One pair of the
guides f, f, for the stamps is shown in side view in Figure 2, and the
cap piece d is here seen in section; Figure 3 is a plan of a portion of
the cap piece d with the timber upon it, and the stamps are shown in
section; Figure 4 is a horizontal section of a portion of the machine,
the section is taken through the axis h and through the outer stamp of
the series; Figure 5 is a horizontal section taken at the level of the
line A, B, Figure 1, through two of the intermediate stamps with their

page_text: guides; this Figure also shows one of the guides fin section taken at
the line C, D, Figure 2; Figure 6 is a back view of a portion of the
machine with some of the parts removed and other parts in section;
Figure 7 is a transverse section of the lower part of the machine with
the anvil or bed and side guards complete; Figure 8 is a horizontal
section of a portion of the machine showing the anvil or bed and side
guards in plan; Figure 9 is a front view of a part of the anvil or bed and
of the standard a on which it rests at its ends; Figure 10 is an end view
of this part; and Figure 11 is a front view of part of one of the side
guards and of a portion of the standard supporting it. The anvil or bed
consists of a strong beam o supported at its ends on the standards a, and
on this beam are keyed the blocks o¹ of chilled cast iron or steel. These
blocks are formed with longitudinal and transverse cutting edges, as the
Drawings show. p, p, are the side guards; they are bolted to the cross
beams, 2, fixed to brackets on the standards a, a, and connecting the
standards together. The side guards are formed with inclined fingers pl
at such a distance apart as to prevent the stone or material passing
between them until it is broken as small as is desired. The stone or
material is placed on the table n, and it slides down with little or no
assistance from the workman until it gets under the stamps, and then
when sufficiently broken it falls away between the fingers p¹. If it be
required that the broken material should be sifted it may fall upon a
riddle mounted underneath the anvil or bed, but in the Drawings no
riddle is shown.
Hammers may be constructed in the manner above described, the
anvil being then of the ordinary description, and usually only one striker
or stamp will be required. In pile-driving apparatus the pile takes the
place of the anvil, and the length of the stamp may advantageously be
increased to admit of the stamp following the pile in its descent, so that
frequent re-adjustment of the machine may not be necessary.
Having thus described the nature of our said Invention, and the
manner of performing the same, we would have it understood that what
we claim is, the constructing machinery for breaking stone and ore,
hammers, pile-driving machines, and other machines in which weights
have to be raised and suddenly dropped in such manner that the stamp
or hammer or weight may be lifted by the friction against it of a friction
wheel or pulley continuously revolving and with a notch or notches in
it, which as they come round release the stamp or hammer or weight,

page_text: and allow it to fall on the ore, mineral, or other substance or instrument
to be operated on.
We also claim the constructing machinery for breaking stone and ore,
substantially as herein described.
In witness whereof, I, the said Sydney Courtauld, have hereunto set
my hand and seal, this Twenty-second day of April, in the year
of our Lord One thousand eight hundred and seventy.
