PROVISIONAL SPECIFICATION.
Improvements in Stamp Batteries and Stamping Mills.
I, WATSON FOGGO, of 26 Queens Road, Erith, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved system of constructing stamp
batteries and stamp mills in order that a more compact arrangement may be made,
and an economy of space and material effected in the method of constructing and
erecting such mills and batteries, than is at present possible with the existing
systems of construction now in use.
In carrying my invention into effect I arrange my battery in the form of a
number of radial stamps mounted about or round a central driving shaft the stems
being made to move up and down in guides placed radially about the frame, so that
the mill which is produced is of a circular instead of a rectangular system having
any number of stamps arranged upon one mill, as for example ten forming one
battery or set to suit the particular requirement or demand for the special mill
which is to be constructed.
I give the reciprocating motion to each of the stems by means of a continuously
rotating horizontal disc or plate having a number of inclined paths or cam-like
surfaces arranged thereon which cause the tappets to move up and down upon
their inclined or rising and falling surfaces, and thus to produce the necessary blow
upon the shoe. I arrange my stamps to work in guide blocks mounted preferably
in the form of segments of wood or other suitable material carried in a casing or
framework at the upper end of the mill, and in a similar series of guides placed
near the lower end of the mill; and on each stem 1 place an adjustable tappet
which may be altered in position to suit the necessary stroke which may be
demanded for any particular stamping operation.
I reduce the friction upon my operating cam disc or central rotating path in one
convenient manner by means of a ring of live rollers or other anti-friction devices
upon which the disc rotates, and I give motion to this disc by means of gearing,
bevel or worm, or by other suitable well-known means driven in any ordinary
manner.
I arrange the feeding hopper in the central portion preferably of my framework,
and I provide a series of openings or shoots at the lower end of this hopper to
deliver the material to be operated upon to the anvil block or blocks arranged
about the bed or foundation of my mill. I strengthen the hopper by means of ribs
arranged in any suitable manner, and I form inclined shoots or delivery slides at
the base of the hopper for preventing choking of the material within the same.
I provide a number of doors for giving access to the mortar box and for enabling the
dies to be cleared, the doors being arranged in a cylindrical manner about the
cylindrical mortar box chamber or formed in any well known manner as at present
employed, but modified to suit the improved form of cylindrical mortar box and
bed which I employ.
I make my framework for carrying my mill of any suitable material or suitable
configuration, employing any well-known forms of tappets, stamp head, stems,
shoes, and dies as now employed in ordinary stamping mills and batteries, modified
only to the extent necessary to enable them to be mounted in a circular manner in

page_text: my improved mill and battery as hereinbefore described. I arrange around the
lower portion of my mortar box casting or frame a trough of any suitable
configuration into which the crushed material can be withdrawn and delivered into
any desired position from a mouth or mouths which may be formed therein.
I do not limit the application of my invention to a mill having any special
number of stems about one framework, or to a mill having any special form of shoe
or mortar, but I modify the same to suit the improved combination and method of
actuating the motions of each stem as hereinbefore described.

Improvements in Stamp Batteries and Stamping Mills.
I, WATSON FOGGO, (formerly of 26 Queens Road, Erith, in the County of
Kent), but now of Anna Valley, Andover, in the County of Hants Engineer 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 has reference to an improved system of constructing stamp
batteries and stamp mills in order that a more compact arrangement may be made,
and an economy of space and material effected in the method of constructing and
erecting such mills and batteries, than is at present possible with the existing
systems of construction now in use.
In the two accompanying sheets of explanatory drawings-
Figure 1 is a sectional elevation and
Figure 2 a sectional plan of one form of my improved battery.
Figure 3 is a side elevation of my complete stamp battery shown in connection
with a known feeding arrangement and
Figure 4 is a plan of the same.
Figure 5 is a sectional elevation of an alternative driving arrangement of my
stamps and
Figure 6 is a plan of the same.
In carrying my invention into effect I arrange my battery in the form of a
number of radial stamps A mounted about or round a central driving shaft B the
stems A being made to move up and down in guides C placed radially about
the frame D so that the mill which is produced is of a circular instead of a
rectangular system having any number of stamps arranged upon one mill, as for
example ten, as illustrated in Figures 1 to Figure 6 forming one battery or set to
suit the particular requirement or demand for the special mill which is to be
constructed.
I give the reciprocating motion to each of the stems A' by means of a con-
tinuously rotating horizontal disc or plate E having a number of inclined paths or
cam-like surfaces F arranged thereon which cause the tappets G to move up and
down upon their inclined or rising and falling surfaces, and thus to produce the
necessary blow upon the shoe H. I arrange ny stamps to work in guide blocks
mounted preferably in the form of segments of wood or other suitable material
carried in a casing or framework C at the upper end of the mill, and in a similar
series of guides carried in a casing or framework C' near the lower end of the
mill; and on each stem I place an adjustable tappet G which may be altered in

page_text: position to suit the necessary stroke which may be demanded for any particular
stamping operation.
I reduce the friction upon my operating cam disc or central rotating path E.
in one convenient manner by means of a ring of rollers K or other anti-friction
devices upon which the disc rotates, and I give motion to this disc by means of
gearing e el bevel or worm or by other suitable well-known means driven in any
ordinary manner.
When providing for a clear and uninterrupted entrance to the central feeding
trough from above I make my driving disc or plate as shown in Figures 5 and 6.
An annular bevel ring E' formed upon or attached to the disc driving ring carrying
the cam ring F being set in motion by a short spindle or shaft B' and the bevel
pinion . I vary the method of driving the disc or cam ring to suit the form of
mill and number of stamps to be provided for.
I arrange the feeding hopper L (Fig. 1) in the central portion preferably of my
framework, and I provide a series of openings or shoots at the lower end of this
hopper to deliver the material to be operated upon to the anvil block or blocks M
arranged about the bed or foundation of my mill. I strengthen the hopper by
means of ribs arranged in any suitable mauner, and I form inclined shoots or
delivery slides at the base of the hopper for preventing choking of the material
within the same. I provide a number of doors N for giving access to the mortar
box M and for enabling the dies to be cleared, the doors being arranged in a
cylindrical manner about the cylindrical mortar chamber or formed in any well
known manner as present employed, but modified to suit the improved form of
cylindrical mortar box and bed which I employ.
I make my framework for carrying my mill of any suitable material or of any
suitable configuration, employing any well-known form of tappets, stamp head,.
stems, shoes, and dies as now employed in ordinary stamping mills and batteries,
modified only to the extent necessary to enable them to be mounted in a circular
manner in my improved mill and battery as herein before described. I arrange
around the lower portion of my mortar box casting or frame a trough M2 of any
suitable configuration into which the crushed material can be withdrawn and
delivered into any desired position from a mouth M³ or mouths which may be
forined therein.
I do not limit the application of my invention to a mill having any special
number of stems about one framework, or to a mill having any special form of shoe
or mortar, but I modify the same to suit the improved combination and method of
actuating the motions of each stem as hereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The improvements in constructing and arranging stamp batteries or stamping
mills substantially as and for the purposes hereinbefore described aud as illustrated
in the accompanying drawings.
2. In a stamp battery or stamp mill the arrangement of circular or segmental
guide in connection with or upon the mill for permitting the stamp stems to be
mounted and placed in a circular or radial manner substantially as hereinbefore
described and as illustrated in the accompanying drawings.
3. In stamp batteries the arrangement of a circular mortar box having a number
of anvils arranged in a circular or radial path therein substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
4. In a stamp battery or mill a series or set of tappet stamps arranged in a
radial or circular manner and having the stems working through guides carried
upon the framework of the battery or mill, each stamp being raised by a cam plate
or plates driven by a disc plate or ring revolving upon anti-friction or other
bearings substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.

page_text: 5. In stamp batteries the improved methods and arrangements for actuating the
motion of each stem or stamp substantially as hereinbefore described and as
illustrated in the accompanying drawings.
