PROVISIONAL SPECIFICATION.
Improvements in Stamp Batteries.
We, JOHN FREDERICK WEBB, of 83, Bridge Road, Battersea, in the County of
Surrey, Engineeer, JOSEPH EDWARD LILLEY, of The Chestnuts, Wealdstone, in the
County of Middlesex, Gentleman, and JOHN CHAPMAN, of 81, St. Mary's Road,
Ealing, in the County of Middlesex, Gentleman, do hereby declare the nature of
this invention to be as follows:-
This invention relates to stamp batteries, and has for its object the arrangement
and subdivision of the mortar box of a multi-stamp battery, so that the efficiency of
the machine is greatly increased. Less slimes are made than is usually the case,
and further the important advantage is obtained, that one or more stamping heads
can be put out of operation for repairs or other purposes, without stopping the whole
machine.
In order to carry this invention into effect we surround each stamp with an
enclosing screen, the lower end of the screen being adapted to be supported in the
bottom of the mortar box.
These screens are so arranged that a space is left between adjacent screens,
so that the delivery of the material from the stamps takes place on all four
sides.
If necessary the screens may be divided from top to bottom, and jointed by any
suitable means to allow of the said screens being placed in position around the stamp
heads; and detachably attached to the mortar box on its frame.
In order to keep the screens clean I arrange around the top edge of the same, a
water pipe having slits or holes therein, so arranged as to project a stream of water
down the face or faces of the screen and thus wash down any material that may be
adhering thereto.
The great advantage of the sub-division of the mortar-box into independent com-
partments for each stamp head is that in a battery made according to this invention :
the material under one stamphead is not driven outwards under the next stamp-
head, or under other stamp-heads, and consequently very much less slime is
made.
We are aware that a mortar-box has been fitted with a screen around its sides, and
enclosing the whole of the stamps, in one compartment formed by the screens, and
we would have it understood that this invention does not consist of this arrangement,
but of the subdivision of the mortar box into separate compartments by enclosing
screens, so as to allow the discharge from the stamps to take place at every side of
the screens.

We, JOHN FREDERICK WEBB, of 83, Bridge Road, Battersea, in the County of
Surrey, Engineer, JOSEPH EDWARD LILLEY, of The Chestnuts, Wealdstone, in the
County of Middlesex, Gentleman, and JOHN CHAPMAN, of 81, St. Mary's Road, Ealing,
in the County of Middlesex, Gentleman, 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 stamp batteries, and has for its object the arrangement
and subdivision of the mortar box of a multi-stamp battery, so that the efficiency of
the machine is greatly increased, less slimes are made than is usually the case, and
further the important advantage is obtained, that one or more stamping heads can be
put out of operation for repairs or other purposes without stopping the whole
machine.
In order that our invention may be the better understood we will now describe it
in relation to the accompanying drawings, reference being had to the letters and
figures marked thereon. Like letters refer to like parts in the figures.
Figure 1 is a side elevation of a stamp battery according to my invention.
Figure 2 is a front elevation of the same.
Figure 3 is a plan of the mortar box and screens.
To carry out our invention we surround each stamp A with an enclosing screen B, the
lower end of which engages with and is supported by the bottom of the mortar box C..
The several screens B are so arranged relatively to one another that a space is left
between adjacent screens so that the delivery of the material from the stamps takes
place on all four sides.
The screens B are divided from top to bottom and are jointed by means of a split
tube engaging over the adjacent edges which are bent to form an engagement.
This allows the screens to be readily attached to and detached from the mortar box
for the purposes of renewal. We arrange water pipes if necessary to wash the surfaces
of the screens and stamp heads.
The great advantage of the subdivision of the mortar box into independent
compartments for each stamp-head is that in a battery made according to this
invention the material under one stamp-head is not driven outwards under the next
stamp-head or under other stamp-heads but is delivered through the screen to the
outside thereof, consequently very much less slime is made than under ordinary
circumstances.
In order to provide for the wear and tear of the stamps we provide movable packing
pieces D. The other features of construction of the battery are similar to those in
general use and need not be further described.
We are aware that a mortar box of a multi stamp battery has been fitted with a
screen around its sides and enclosing the whole of the stamps in one compartment
formed by the screens, and we would have it understood that this invention does
not consist of this arrangement but of the subdivision of the mortar box into separate
compartments by enclosing screens, so as to allow the discharge from the stamps to
take place at every side of the screens.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In a multi stamp battery. the arrangement of an independent screen around each

page_text: stamp, adapted to allow of the lateral discharge of material all round the said stamp
through the same but to prevent its passage under the adjacent or other stamps of the
series, substantially as described.
