Managing Director of The Universal Inventors and Patentees Financial
Company Limited, 30 Finsbury Pavement London E.C. for an Invention of
"A NEW OR IMPROVED APPARATUS FOR WASHING CLAY AND OTHER SIMILAR
SUBSTANCES communicated to him from abroad by Lorentz Ramberg,
a person resident at Helsingborg, in the Kingdom of Sweden.
"
PROVISIONAL SPECIFICATION left by the said Lorentz Albert Groth at
the Office of the Commissioners of Patents on the 10th January 1883.
LORENTZ ALBERT GROTH K.G.V Civil Engineer and Managing Director of The
Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. "A NEW OR IMPROVED APPARATUS FOR WASHING CLAY
AND OTHER SIMILAR SUBSTANCES" A communication to me from abroad by
Lorentz Ramberg, a person resident at Helsingborg in the Kingdom of Sweden,
The object of this invention is to effect the washing of clay and other similar
substances not only thoroughly, but at a working expense of about one fifth
of what is the usual cost when accomplished with the washing appliances
hitherto used.
The apparatus consists of an axle which rests on two trestles in plumber blocks
made of beech or any other suitable kind of wood, metal plumber blocks have
been found loss serviceable
The said axle is joined by means of supports to a pyramidical drum of hard
wood and if requisite lined on the inside with sheet iron.
Inside this drum is what I call the spiral which is made of sheet iron together
with a number of knives The parts of the spiral are screwed fast to elbows of
cast iron fastened on the sides of the drum and the knives together with the elbows
forming one piece.
A support furnished with a flange and to which the wooden side of the drum is
fixed with screws, forms one of the bottoms of the drum.
This bottom which is joined by means of arms to a centre which is placed on

page_text: and united with the axle and has in the middle of it an orifico round which the
concave orifice of the apparatus is fastened
The edge or mouth of this orifice is so constructed as to receive a suitable funnel
for feeding, the other end of the funnel being secured to or resting on the feeding
table.
The movement of the apparatus is obtained by means of an endless strap or cord
working in a groove provided for that purpose
A second support for the spiral or working part of the machine is provided
consisting of a ring of cast iron or the like which by means of arms join the axle
of the drum.
A third support resembling the first in appearance but on one side furnished
with Banges for the fixing of the wooden side and having a flange to which the
ends of a number of iron arms are screwed.
The other ends of these iron arms are fixed to a fourth support which is furnished
with a groove for the application of an endless strap in case an elevator should be
used for removing the waste from the washing
In flanges on the above named iron arms rest gratings of cast iron finely
pierced
The fourth support is likewise pierced and also furnished with a progecting
funnel shaped mouth forming the outlet of the apparatus.
When the apparatus is used the matter or substance to be washed is introduced
into the funnel at the feeding end of the apparatus whilst the drum is rotating
and water simultaneously flowing in.
The mass is worked forwards by the spiral and at the same time is divided or
cut asunder by the knives, when the washed mass then falls down through the
gratings into a gutter or trough placed underneath the apparatus and leading to
an evaporating basin, whilst the stones, gravel &c intermixed with the mass falls
down through the orifice in the fourth support into a trough and are removed
therefrom by means of trollies, carts or in any other suitable manner.
The extension or pitch of the spiral as well as the number of the knives depends
upon the nature of the substance intended to bo worked but to 20 worms of the
spiral are generally reckoned 480 knives.
The apparatus may be driven either by steam, water, wind or horse power
and is capable of working up when regularly fed about 250 or 300 cubic feet of clay
per hour.

by the said Lorentz Albert Groth in the Great Seal Patent Office on the
10th July 1883.
LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director of The
Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. A NEW OR IMPROVED APPARATUS FOR WASHING CLAY
AND OTHER SIMILAR SUBSTANCES a communication to me from abroad by Lorentz
Ramberg, a person resident at Helsingborg in the Kingdom of Sweden
The object of this invention is to effect the washing of clay and other similar
substances not only thoroughly but at a working expense of about one fifth
of what is the usual cost when accomplished with the washing appliances
hitherto used
The apparatus consists of an axle A which rests on two trestles G. G. Fig 1 in
plumber blocks made of beech or any other suitable kind of wood, metal plumber
blocks having been found less serviceable
This axle A is joined by means of supports B' B B B to a pyramidical drum X
of hard wood and if requisite lined on the inside with sheet iron
Inside this drum is what I call the spiral Y Fig 1. & 5 which is made of sheet
iron together with a number of Knives Z Figs 4 & 5.
The parts of the spiral Y are screwed fast to elbows of cast iron fastened
on the sides of the drum and the Knives Z together with the elbows forming
one piece
A support B, Fig 1 & 3, furnished with a flange a, to which the wooden side p
of the drum is fixed with screws, forms one of the bottoms of the drum
This bottom which is joined by means of arms r fig 1 and 3, to a centre r¹ which
is placed on and united with the axle A and has in the middle of it an aperture
to which the concave orifice is fastened
The edge or mouth of said orifice is so constructed as to receive a suitable
funnel F for feeding, the other end of the funnel being secured to or resting on the
feeding table m
The movement of the apparatus is obtained by means of an endless strap or cord
working in a groove 6 provided for that purpose.
b
A second support B² for the spiral or working part of the machine is provided
consisting of a ring of cast iron or the like which by means of arms join the axle A
to the drum.
A third support B³ Figs 1 & 2 resembling the first in appearance but on
one side is furnished with flanges C for the fixing of the wooden side of the
drum and also having a flange d Fig 1. to which the ends of a number of iron.
arms are screwed
The other ends of these iron arms C' Figs 1.6.7 are fixed to a fourth support B
Figs 1 &7 which is furnished with a groove g for the application of an endless
strap in case an elevator should be used for removing the waste from the
washing
In flanges C on the above named iron arms C₁ rest gratings D made of cast iron
finely pierced
The fourth support B' is likewise pierced and provided with a projecting funnel
shaped mouth or outlet of Fig 1.
When the apparatus is used the matter or substance to be washed is introduced
into the funnel at the feeding end of the apparatus whilst the drum X is rotating
and water simultaneously flowing in

page_text: The mass is worked forwards by the spiral Y and at the same time is divided
or cut asunder by the Knives Z upon which the washed mass falls, then passing
down through the gratings D into a gutter or trough W placed underneath
the apparatus and leading to an evaporating basin whilst the stones gravel &c
intermixed with the mass falls down through the orifices in the fourth support
into the gutter H and are removed therefrom by trollies carts or any suitable
mechanical means
The extension or pitch of the spiral X as well as the number of the Knives Z
depends upon the nature of the substances intended to be worked but to 20 worms
of the spiral might generally be reckoned 480 Knives
The apparatus may be driven either by steam, water, wind, or horse power
and is capable of working when regularly fed about 250 to 300 cubic feet of clay
per hour.
Having now described the nature of the said invention and the manner in which
the same is to or may be carried into effect I would have it understood that what
I claim to be secured by the within in part recited Letters Patent is.
An apparatus for washing clay and other similar substances consisting of a
conical drum X in the inside of which the frame work in spiral form Y is placed
to which are attached Knives Z, orifices being provided through which pass the
stones, gravel, &c, substantially as herein described and set forth
In witness whereof I the said Lorentz Albert Groth have hereunto set my
hand seal [sic] this ninth day of July in the year of Our Lord One thousand eight
hundred and eighty three.
