of our said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF MANURE

"
In carrying out this Invention we cast a "mould or blank of
crucible cast steel with the required number of "tines or prongs" in
a much shorter and thicker form than the finished prong, and so spread
out that each separated prong may be easily brought under the action of
a steam hammer or other suitable forging appliance to be drawn out and 5
finished in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis George Pearson and James Grinold in the
Great Seal Patent Office on the 2nd June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, FRANCIS

license, that we, the said Francis George 'Pearson and James Grinold,
our exccutors, administrators, and assigns, or such others as we, the
said Francis George Pearson and James Grinold, our executors, admini-

time to time and at all times thereafter 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,

OF MANURE AND OTHER SIMILAR FORKS," upon the condition (amongst others)
that we, the said Francis George Pearson and James Grinold, our execu-

page_text: NOW KNOW YE, that we, the said Francis George Pearson and James
Grinold, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the accompanying Drawings and to the letters and figures marked
thereon, that is to say :-
This Invention consists in casting in crucible cast steel the "mould"
or blank of a manure or other like fork instead of forging the same as
heretofore.
In carrying out this Invention we cast a "mould" or blank of crucible
cast steel with the required number of "tines or prongs in a much
shorter and thicker form than the finished prong, and so spread out that
each separated prong may be easily brought under the action of a steam
hammer or other suitable forging appliance, to be drawn out and finished
in the usual manner.
And in order that our said Invention may be fully understood we
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts in
all the Figures.
Figure 1 represents the blank or form in which according to our
Invention the tines or prongs a, a, for a four-pronged manure or other
similar fork are first molded and cast in crucible cast steel, the said
tines or prongs being much shorter and thicker than the same when
finished, and they are spread out, as shewn, so as to subject them
respectively to the action of a steam hammer, or other forging appliance,
or pressure, whereby each tine or prong a is drawn out into the shape
seen in Figure 2, the whole being finally bent and worked into the
finished state as seen in Figure 3.
Hitherto manure and other similar forks have been made and finished
of forged steel which is an expensive process. By this Invention the
cost of their construction is considerably lessened.
Having now described and particularly ascertained the nature of our
said Invention and the manner in which the same is or may be used
or carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured

page_text: to us by the herein-before in part recited Letters Patent is, manu-
facturing manure and other similar forks of "crucible cast steel,"
substantially as and for the purpose herein-before described and illustrated
by our Drawings.
In witness whereof, we, the said Francis George Pearson and James
Grinold, have to this our Specification set our hands and seals,
this First day of June; One thousand eight hundred and seventy-
four...
