Year: 1884

page_text: I, WILLIAM GEORGE STRYPE, of The Wicklow Chemical Works, The Murrough,
Wicklow, Ireland seek leave to amend the Specification of Letters Patent, No. 787"
of 1884, as shown in red ink in the copy of the original Specification hereunto
annexed:-
My reasons for making this amendment are as follows:-
That there are doubts whether the use of sulphate of iron in the manner
described in the said Specification is of any commercial value, and that the words
"other analogous materials" used in the said Specification may possibly be held to
be too vague and indefinite and it is doubtful whether the claim to the use of such
analogous materials can be supported.
That there are clerical errors in the said Specification which I am desirous of
correcting.
That the other alterations are rendered necessary or convenient by the proposed
Amendment,
Dated this 28th day of July 1884.
In the matter of Strype's application for leave to amend the Specification to
Letters Patent No 787 of 1884.
I hereby grant leave to the said William George Strype to amend the said
Specification in the manner proposed.

page_text: I WILLIAM GEORGE STRYPE of Wicklow Ireland Do hereby declare the nature
of my said Invention for "IMPROVEMENTS IN THE TREATMENT OF BLOOD TO
PREPARE IT FOR USE AS A MANURE OR FOR OTHER PURPOSES to be as
follows:-
"
My Invention relative to improvements in the treatment of the Blood of
Animals so as to abate the nuisance and also to facilitate the process of preparing
it for use as a manure or for other purposes where it is important to arrest
decomposition and preserve it.
Sulphate of Alumina, Alum, Sulphate of Iron or other analogous materials
which are known to have the power of abating the nuisance attending the process
of drying Blood have not hitherto been successfully employed owing to the
difficulty in properly associating such materials and the blood together. According
to my Invention I form either any or all of the said materials into a solution and
add such solution to the Blood as soon as conveniently may be after the blood is
obtained and I thoroughly incorporate them together. This I am able to effect in
a satisfactory way owing to the materials being previously prepared in solution
which permits of its being readily incorporated with the blood thus abating the
nuisance which has hitherto arisen from the preparation of blood and allowing the
drying to be proceeded with unattended by objectionable inconvenience.
A proportion of about one part of Sulphate or analogous material to fifty parts
of blood fresh from Animals will be found suitable but I do not bind myself to
that proportion.
The mixture may be allowed to stand together in tanks when the material can
act more completely upon the Blood and subsequently the said mixture may be
dried either naturally. or artificially to prepare it for use.

page_text: I WILLIAM GEORGE STRYPE of the Wicklow Chemical Works, The Murrough
Wicklow Ireland Manufacturing Chemist do hereby declare the nature of said
invention for "IMPROVEMENTS IN THE TREATMENT OF BLOOD TO PREPARE IT FOR
USE AS A MANURE OR FOR OTHER PURPOSES" 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 relative to improvements in the treatment of the Blood of
Animals so as to abate the nuisance and also to facilitate the process of preparing
it for use as a manure or for other purposes where it is important to arrest
decomposition and preserve it.
Sulphate of Alumina, and Alum, Sulphate-of Iron-or-other-analogous materials
which are known to have the power of abating the nuisance attending the process
of drying Blood have not hitherto been successfully employed owing to the
difficulty in properly associating such materials and the Blood together. According
to my Invention I forin Sulphate of Alumina or Alum either-any-or-all-of-the-
said materials into a solution and add such solution to the Blood as soon as
conveniently may be after the Blood is obtained and I thoroughly incorporate
them together. This I am able to effect in a satisfactory way owing to the
materials being previously prepared in a solution which permits of its being readily
incorporated with the blood thus abating the nuisance which has hitherto arisen
from the preparation of blood and allowing the drying to be proceeded with
unattended by objectionable inconvenience.
A proportion of about one part of sulphate of alumina or alum or analogous
material to fifty parts of blood fresh from animals will be found suitable but I do
not bind myself to that proportion.
The solution may be prepared with one or more parts of water to one part of
the sulphate of alumina or alum but the best proportions can easily be settled to
suit the circumstances of each case. If warm water be employed the sulphate
of alumina or alum will be dissolved more readily.
The prepared solution is added in any convenient way and stirred up with the
blood in collecting Tanks made of timber or other suitable material.
It will be found a useful practice to flush the floors or conduits leading from the
slaughter room to the collecting tanks with the necessary quantity of the prepared
solution which will thus keep any blood adhering to the floors and conduits free
from decomposing.
The mixture may be allowed to stand together in the tanks when the material
can act more completely upon the blood and subsequently the said mixture may be
dried either naturally or artificially to prepare it for use.
The blood when dried after the treatment with the solution may be washed
with water to get rid of excessive Sulphate but it should be immediately re-dried
if washed in this manner.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
Treating blood by means of a solution of Sulphate of Alumina or Alum, Sulphate
of-Iron-or-analogous-materials substantially as herein before described.
Dated this Seventh day of February 1884.
