I, WILLIAM MOLEAN of Grafton Street, Goulburn in the Colony of New South
Wales, Miner do hereby declare the nature of this invention to be as follows:―
This invention relates to that kind of quartz crushing machines in which
stampers are lifted by cams or inclined planes upon a circular frame or wheel and
it has been devised so that the amount of lift of such stampers may be adjusted
and so that the stampers will be arranged closely together in a small box-The
adjustable cams or inclined planes may of course be used for any purpose where a
reciprocating motion is required.
My improvements consist first in hinging the cams or inclined planes to the
periphery of the wheel or frame at their lowest point and supporting their upper
ends by standards from said periphery the length of which standards is adjustable
and my second improvement consists in arranging the stampers close to one
another so that a line through their centres will be part of the circumference of a
circle and placing them in a box of a segmental form in plan.
But in order that my invention may be clearly understood reference will now be
made to the drawings herewith in which Figure 1 is a plan of a quartz crushing
machine having my improvements attached-Figure 2 shows elevation of a some-
what similar arrangement to that of Figure 1 save that the machinery actuated
takes the form of a pump-Figure 3 is a side elevation of part of Figure 1 showing
part of the circular frame or main wheel and a cam or inclined plane-Figure 4 is
a front elevation of the same and Figure 5 a plan of the stamps and stamper box
while Figure 6 is a partial inside elevation of the main wheel to show the
construction of the cams or inclined planes.
The parts of such a machine are constructed and it is worked as well understood
and I will refer only to such parts necessary to illustrate my invention.
A is the main wheel or frame and B the cams or inclined planes-C are the
stampers and D the stamper box-B¹ is the hinge or pin on which inclined
planes B are adjusted-B B* are supports or standards B³ stay whose length is
adjusted by means of bolt B-B aliding wedges-B binding plate-B' set
screws To alter the amount of lift it is only necessary to loosen set screws B' and
bolt B and adjust the inclined plane B upon the pin B¹ to the angle which will

page_text: give the required height-The wedges B are then placed tightly under the
supports B and the bolt B tightened as also the screws B' which latter fasten
the standards B³ wedge B and binding plate B on to the periphery of the
wheel A.
It will be seen that stampers C are arranged closely together in box D and that
they are so arranged that their centres are equally distant from the centre of the
main wheel A-The box D is constructed of a segmental form in plan as shown
and is fed under the wheel from trough D¹ through opening D' which may be
regulated by sliding door D³-The arrangement of the stampers as shewn will
allow of combining the whole in a small space.
I have found that this construction makes a handy and convenient machine for
the purpose described and for pumping and having thus particularly described
and ascertained the nature of my invention I would have it understood that I am
aware that such class of machines are now in use and I do not claim to have
invented them but what I believe to be new I will hereafter claim as my
improvements in quartz crushing machines parts of which are applicable to other
purposes.

I, WILLIAM MOLEAN of Grafton Street, Gouburn in the Colony of New South
Wales, Miner, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to that kind of quartz crushing machines in which
stampers are lifted by cams or inclined planes upon a circular frame or wheel and
it has been devised so that the amount of lift of such stampers may be adjusted,
and so that the stampers will be arranged closely together in a small box. The
adjustable cams or inclined planes may of course be used for any purpose where a
reciprocating motion is required.
My improvements consist first in hinging the cams or inclined planes to the
periphery of the wheel or frame at their lowest point and supporting their upper
ends by standards from said periphery the length of which standards is adjustable
and my second improvement consists in arranging the stampers close to one
another so that a line through their centres will be part of the circumference of
a circle and placing them in a box of a segmental form in plan..
But in order that my invention may be clearly understood reference will now be
made to the drawings herewith in which Figure 1 is a plan of a quartz crushing
machine having my improvements attached Figure 2 shows elevation of a some-
what similar arrangement to that of figure 1 save that the machinery actuated
takes the form of a pump. Figure 3 is a side elevation of part of figure 1 showing
part of the circular frame or main wheel and a cam or inclined plane. Figure 4 is
a front elevation of the same and Figure 5 a plan of the stamps and stamper box
while Figure 6 is a partial inside elevation of the main wheel to show the
construction of the cams or inclined planes.
The parts of such a machine are constructed and it is worked as well understood
and I will refer only to such parts necessary to illustrate my invention.
. A is the main wheel or frame and B the cams or inclined planes C are the
stampers and D the stamper box-B¹ is the hinge or pin on which inclined
planes B are adjusted-B B are supports or standards-B³ stay whose length is
adjusted by means of bolt B-B' sliding wedges Be binding plate-B7 set screws.
To alter the amount of lift it is only necessary to loosen set screws B' and bolt B*
and adjust the inclined plane B upon the pin B₁ to the angle which will give the
required height. The wedges B³ are then placed tightly under the supports B²
and the bolt B' tightened as also the screws B' which latter fasten the standards B
wedge B and binding plate B onto the periphery of the wheel A.
It will be seen that stampers C are arranged closely together in box D and that
they are so arranged that their centres are equally distant from the centre of the
main wheel A. The box D is constructed of a segmental form in plan as shown.
and is fed under the wheel from trough D' through opening D' which may be

allow of combining the whole in a small space.
I have found that this construction makes a handy and convenient machine for
the purpose described and for pumping and I would have it understood that I am
aware that such class of machines are now in use and I do not claim to have
invented them but
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. The combination and arrangement with a circular frame or main wheel of
adjustable cams or inclined planes the height and inclination of which may be
varied substantially as herein described and explained.
Second. The particular combination and arrangement of parts marked A. B.
B¹ B³ B³ Bª and B' with or without the parts marked B³ and B*, substantially as
herein described and explained and as illustrated in the drawings.
Third. The particular arrangement of stampers C arranged upon the circumference
of a circle closely together in a segmental box D substantially as herein described
and explained and as illustrated in the drawings.
