I ELIZABETH HARRIOTT HUTCHINSON, 30 Wolsey Road, Mildmay Park, London,
Gentlewoman, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to compress sea salt, or it may be partly sea salt,
and partly common or other salt or chemicals having the same properties which may
or may not be ground, refined, dried, or in a moist or dry state. Compressed or
consolidated by Hydraulic or other pressure with or without moulds to any required
shape or form, which may or may not be solid, such as Rolls, Blocks, Cylinders,
Tablets, Plates, Balls, Pyramids, Spirals, or Helices, or any other desired shape or
form which can be fluted, corrugated, perforated or plain which may or may not be
mado porous during compression or after compression by drilling holes therein or
otherwise by inserting in the compressed material such as wires, gauze wires, wood
perforated, plain or cylindrical, which may or may not be withdrawn from the com-
pressed material, or any other suitable device may be employed which gives a large
amount of surface to the water which may enter the Rolls, Blocks, or Cylinders, in
the centre, forming a spray through the holes thereof, or over the outside in the caso
where the rolls or Blocks are solid. The said Rolls, Blocks, Balls, Pyramids, Plates,
Helices, or other forms can be fitted to cisterns, baths, filters or other devices or in
connection with pipes leading to or therefrom in such a manner that the various
strengths of the impregnated water can be readily adjusted, and the compressed
material easily replaced, which may be held in cages or frames or any suitable device
with, or without bearings, so that the compressed material may or may not revolve
therein.

page_text: I, ELIZABETH HARRIOTT HUTCHINSON, of 40 Queen Margaret's Grove, Mildmay
Park, Middlesex, Gentlewoman, 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 the preparation or production of a compressed body of
any desired form said body being composed chiefly of sea salt or common salt or a
combination or of a chemical having salt properties and in a raw state or so treated
that the particles by compression adhere and constitute a block of any desired
shape (solid or hollow) so that when applied for the purpose of impregnating
water which may be caused to flow over it or the block be reduced for immersion
it can be used by itself for the water of a tap to flow over it or it may be enclosed in
a casing to be applied to a tap or otherwise used according to requirements.
The annexed drawings show several forms to which I compress salt or salty
compound.
Figures 1 and 2 represent a block A in cylindrical form compressed with a
spindle B through its interior with projecting ends for dropping into slots of
brackets C attached to a wall or to the side of a bath as at Figure 3, the block
being within range of a tap D as at Figure 1 or a rose E as at Figure 3 so that
the water flowing therefrom may trickle over and from it and dissolve the same so
that the water is impregnated thereby.
In Figures 1 and 2 I show the cylinder as solid but at Figure 4 I show it with
radial openings so that the water flowing from the tap D may spread over a larger
surface by passing into the radial slots and be kept in contact with the salt block A
for a longer period than is possible by the block shown in Figures 1 and 2.
Instead of my compressed salt block being round as indicated, it may be of any
other shape and in lieu of affixing it horizontally it may be of pyramidal or other
shape and be set on end and supported by a single bracket and the block may be
hollow and provided with apertures or passages at intervals as at Figure 5 through
which the water may flow from the interior after leaving the tap D and thus be
partly impregnated by contact with the interior of the compressed block of salt and
impregnated to a greater extent by being broken into fine streams in passing through
the apertures to the outside of the block.
Instead of the block being in one piece as represented in the foregoing Figures
it may be compressed in tablets as at Figure 6 or washer form and a number of
these can be piled up or put contiguous to one another to be used as above described
or if desired one or more of these cakes or washers of compressed salt may be simply
thrown into the water to dissolve themselves.

page_text: When salt alone is of such a nature that it cannot be compressed without the
addition of a plastic or adhesive material I make a kind of paste with which I mix
the salt and then compress the compound into block, cake, or other form according
to the particular use for which it is intended.
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 :-
Solidifying salt or salty compounds by pressure in a solid or hollow form of any
requisite shape and the application or employment of such blocks for the purpose of
impregnating water in baths as hereinbefore described, the forms or shape of the
blocks being substantially as shown in the annexed drawings.
