Year: 1875

page_text: ETTERS PATENT to William Morgan-Brown, of the Firm of Brandon
and Morgan-Brown, Engineers and Patent Agents, of 38, South-
ampton Buildings, London, and 13, Rue Gaillon, Paris, for the
Invention of "A NEW COMPOSITION OF INGREDIENTS FOR DESTROYING
INSECTS, WORMS, AND SLUGS ATTACKING SHRUBS, TREES, OR PLANTS."-A
communication from abroad by George Washington Davis, of
Boston, Massachusetts, United States of America.
Sealed the 3rd August 1875, and dated the 4th June 1875.
PROVISIONAL SPECIFICATION left by the said William Morgan-
Brown at the Office of the Commissioners of Patents, with his
Petition, on the 4th June 1875.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38, Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of
the said Invention for "A NEW COMPOSITION OF INGREDIENTS FOR DESTROYING
INSECTS, WORMS, AND SLUGS ATTACKING SHRUBS, TREES, OR PLANTS," to be as
follows:-
This Invention of a new composition of ingredients for destroving

page_text: insects, worms, and slugs attacking shrubs, trees, or plants, consists in
the admixture of carbonate of lime, carbonate of magnesia, and iron
pyrites (sulphurets) with an alkali, in such a manner that when the
composition is exposed to the influence of atmospheric changes, the
compound material is gradually decomposed and the carbonic acid gas
released, which is fatal to and will destroy such insect life as may come
within its scope of action.
My compound consists of crude potash, iron pyrites (sulphurets)
dolomite, or a double carbonate of lime and magnesia, carrying about
seventy-five per cent of these carbonates.
I take dolomite to the amount of
and iron pyrites (sulphurets)

To prepare my compound the dolomite and iron pyrites are reduced to
a fine powder by any suitable method. The crude potash is then
dissolved in a sufficient quantity of water, so that on adding the pul-
verized iron pyrites and dolomite, the whole mass will assume the con-
sistency of mortar when in condition to work. This mixture is then
partially calcined in an oven or on a drying furnace until it has become
as hard as chalk, after which it is reduced to an impalpable powder by
any suitable means. This powder is applied about the roots and to
foliage of plants, vines, fruit trees, and shrubs infested by noxious
insects in greater or less quantities as the occasion demands.
By this
application the insects and their eggs on the plants to which the com-
position has been applied are destroyed, and other insects are prevented
from attacking, probably by an evolution of carbonic acid gas under
atmospheric influences; and this powder also has stimulating or
invigorating properties on account of its potash, lime, magnesia, and
carbonic acid gas, and does not injure but assists and promotes the
growth of the plants and vines to which it is applied.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Morgan-Brown in the Great Seal Patent
Office on the 3rd December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13, Rue
Gaillon, Paris, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Morgan-Brown
Her special license that I, the said William Morgan-Brown, my
executors, administrators, and assigns, or such others as I, the said
William Morgan-Brown, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time
and at all times thercafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "A NEW COMPOSITION OF INGREDIENTS FOR DESTROYING
INSECTS, WORMS, AND SLUGS ATTACKING SHRUBS, TREES, OR PLANTS," a commu-
nication to me from abroad by George Washington Davis, of Boston,
Massachusetts, United States of America, upon the condition (amongst
others) that I, the said William Morgan-Brown, my executors or admini-
strators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Morgan-Brown, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
The nature of my Invention consists in the admixture of carbonate of
lime, carbonate of magnesia, protoxide of iron and sulphur with an

page_text: These proportions may be slightly varied without departing from the
spirit of the Invention, but in practice I have found these proportions
to be effectual.
To prepare the compound the dolomite and iron pyrites are reduced to
a fine powder by any suitable method. The crude potash is then
dissolved in a sufficient quantity of water, so that on adding the pul-
verized dolomite and iron pyrites, the whole mass assumes the con-
sistency of "mortar" when in condition to work. The mixture is then
partially calcined in an oven or on a drying furnace until it has become
as hard as chalk, after which it is reduced to an impalpable power by
any suitable means. This powder is applied about the roots and to foliage
of plants, vines, fruit trees, and shrubs infested by worms, grubs, or
noxious insects in greater or less quantities as the occasion demands.
By this application the worms, grubs, and insects, and their eggs at the
roots or on the plants, to which the composition has been applied, are
destroyed, and other insects are prevented from attacking, probably by
an evolution of carbonic acid gas under atmospheric influences, and this
powder has also stimulating or invigorating properties on account of its
potash, lime, magnesia, and carbonic acid gas, and does not injure, but
assists and promotes the growth of the plants, vines, trees, and shrubs,
to which it is applied.

page_text: Although the mixture of dolomite with the other ingredients is a
convenient and economical way of preparing this composition, it may be
made by incorporating oxides of iron with sulphur in powder, and then
mixing in the carbonates of lime and magnesia, adding the potash or
alkali as described.
Having now described and particularly set forth the nature of the
said Invention, and the manner of carrying the same into effect, I
would have it understood that what I claim is,―
First. The composition of matter above set forth as an insect, worm,
and grub destroyer and fertilizer, substantially as set forth.
Second. Mixtures of the carbonates of the alkali, sulphur, and iron
for the purpose set forth, substantially as set forth.
In witness whereof, I, the said William Morgan-Brown, have here-
unto set my hand and seal, this Third day of December, in
the year of our Lord One thousand eight hundred and seventy-
five.
