PROVIDIONAL DIECIFICATION.
Improvements in Ore and like Stamps.
WATSON FOGGO Engineer 26 Queens Road Erith County of Kent do hereby
declare the nature of this invention to be as follows:-
In carying my invention into effect I have the bored taper seat for stem situated
close to bottom of head where shoe is fixed and above the said bored seat the hole
for stem is enlarged so as to be clear of same. At the top of the head I have a
seat prepared in which I put wood, indiarubber or other soft or cushioning material
round the stem, by which means it is relieved from shock due to drop of stamp.
In this stamphead I have only one drift hole which serves both for stem & shoe,
and a hole is cast or drilled at bottom of enlarged hole to allow water to escape.
By the afore described arrangement any length of stamphead can be used without
increasing the amount of leverage which is the case when stem is fixed immediately
at top of stamphead.

I, WATSON FOGGO, of 26 Queens Road, Erith, in the County of-Kent, 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 :-
My invention relates to improvements in the connecting heads for the stamps of
batteries for the crushing of ore and other material, and has for its object to
prevent the premature breaking of the stems and at the same time to facilitate the
detachment of the shoe from the head and the head from the stem.
Referring to the accompanying sheets of explanatory drawings ;-
Figure 1 represents an axial section section of my connecting head showing the
stem of the stamp in position, while,
Figure 2 is a section on the line X Y, Figure 1.
In carrying my invention into effect I provide the connecting head A of
cylindrical form and provide a tapered central seat a within the lower part thereof
for the reception of the correspondingly tapered extremity of the stem B. Upon
the lower extremity of the connecting head is provided an upwardly tapered
seat al for the reception of the shoe, such sent being in line with that of the stem
and a circular recess C1 being provided intermediate of such adjacent seats. On
the placing of the head upon the extremity of the stem and the shoe within the
head, the mere dropping of the stamp fixes the stem and shoe firmly upon their
respective seats, while for detaching the shoe from the head and the head from the
stem a drift hole C is provided, through which a tool may be introduced for this
purpose.
Above the seat of the stem I provide an annular recess D through which at the
upper end of the head I introduce wood, india-rubber or other soft or cushioning

page_text: material E upon a seat provided for the purpose so that the stem may be relieved
from shock on the dropping of the stamp. I provide an outlet a* to allow any
water that may enter such annular space to pass away.
By such construction the stem and the shoe are fixed at closely adjacent positions
so that an extensive leverage and the consequent bending strains which materially
affect the life of the stem, are entirely avoided, while at the same time the shoe and
the head are readily and easily detached when necessary.
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. In stamps for ore batteries and the like a connecting head in which a tapered
seat is provided in the lower portion thereof for the reception of the extremity of
the stamp stem, immediately above and in line with the tapered seat provided
therein for the reception of the shauk of the shoe, and in which an annular seat is
provided at the upper end thereof around the stem for the reception of wood or
other resilient material substantially as and for the purposes herein before
.described.
2. In stamps for ore batteries and the like a connecting head in which a tapered
seat is provided for the reception of the extremity of the stamp stem immediately
above and in line with the tapered seat of the shank of the shoe, and in which a
transverse drift hole is provided through which the extremities of the stem and
shoe protrude substantially as and for the purposes hereinbefore described.
3. In stamps for ore batteries and the like a connecting head substantially as
and for the purposes hereinbefore described and illustrated in the accompanying
drawings.
