IMPROVEMENTS IN THE MANUFACTURE OF HOES ADZES PROVISIONAL SPECIFICATION
Year: 1882

page_text: LETTERS PATENT to Robert Perks Yates of the firm of John Yates and
Company of Birmingham in the County of Warwick Edge Tool Manufacturers
for an invention of "IMPROVEMENTS IN THE MANUFACTURE OF HOES ADZES
PROVISIONAL SPECIFICATION left by the said Robert Perks Yates at the
Office of the Commissioners of Patents on the 22nd April 1882.
ROBERT PERKS YATES of the Firm of John Yates and Company of Birmingham
in the County of Warwick Edge Tool Manufacturers "IMPROVEMENTS IN THE
MANUFACTURE OF HOES ADZES AND MATTOCKS."
In the ordinary method of manufacturing hoes adzes and mattocks a blank or
"mould" of iron is "steeled " and the eye that is the tubular part of the hoe adze
or mattock into which the handle is fixed is first formed either by hand forging or
by dies and pressure from the unsteeled end of the mould. The other part of the
mould is then plated or spread out by percussion and formed into the body of the
hoe adze or mattock By this, the ordinary method of manufacture, the shape of
the eye is injured more or less during the plating out of the body.
In manufacturing hoes adzes and mattocks according to my invention I proceed
as follows. I take the steeled mould and after having heated it to redness I subject
it to pressure in dies so as to form a depression around that part from which the
eye is to be made and at the same time form the rib proceeding from the eye to
the front of the body, or 1 form the said depression and rib by stamping or rolling.
I then plate or spread out the steeled part of the mould so as to form the body of
the hoe adze or mattock and I afterwards raise the part of the mould from which
the eye is to be formed to a welding heat and by dies and pressure or stamping or
rolling form the eye of the hoe adze or mattock.
The eyes of the hoes adzes and mattocks made by the method of manufacture
constituting my invention have a precision and uniformity of size and shape
unattainable in hoes adzes and mattocks manufactured in the ordinary way.

the said Robert Perks Yates in the Great Seal Patent Office on the
14th October 1882.
ROBERT PERKS YATES of the firm of John Yates and Company of Birmingham
in the County of Warwick Edge Tool Manufacturers "IMPROVEMENTS IN THE
MANUFACTURE OF HOES ADZES AND MATTOCKS."
In the ordinary method of manufacturing hoes, adzes and mattocks, a blank or
"mould" of iron is "steeled " and the eye, that is, the tubular part of the hoe,
adze or mattock into which the handle is fixed, is first formed either by hand
forging or by dies and pressure from the unsteeled end of the mould. The other
part of the mould is then plated or spread out by percussion and formed into the
body of the hoe, adze or mattock. By this, the ordinary, method of manufacturo,
the shape of the eye is injured more or less during the plating out of the body.
cyc
In manufacturing hoes, adzes and mattocks according to my Invention I proceed
as follows: I take the steeled mould and after having heated it to redness I subject
it to pressure in dies so as to form a depression between that part from which the
is to be made and the part from which the body is to be made and at the same
time form the rib proceeding from the eye to the front of the body. Or Iform
the said depression or rib by stamping or rolling. I then plate or spread out the
steeled part of the mould so as to form the body of the hoe, adze or mattock and I
afterwards raise the part of the mould from which the oye is to be formed to n
welding heat and by dies and pressure or by stamping or rolling form the eye of
the hoe, ndze or mattock.
The eyes of hoes, adzes and mattocks made by the method of manufacturo
constituting my invention have a precision and uniformity of size and shape
unattainable in hoes adzes and mattocks manufactured in the ordinary way.
Iwill now proceed to describe with reference to the accompanying Drawing-the-
manufacture of a hoe according to my invention.
I take a steeled blank or "mould" of the ordinary kind used in the manufacture
of hoes and having heated it to redness I operate upon it so as to form on one of :
its faces a depression a and at the same time formn the rib b proceeding from the
eye in the finished hoe as represented in front clevation in Figure 1; longitudinal
section in Figure 2 and cross section in Figure 3. The said depression a and
ribb may be produced either by pressure in dies or by stamping or rolling. The
depression a is situated between the unsteeled part c from which the eye is to be a
made and the steeled part d from which the blade or body is to be made. Having
operated upon the blank or "mould" in the manner represented in Figures 1. 2
and 3 I plate or spread out in the ordinary way the steeled part d of the mould so
as to form the body or plate of the hoe and at the same time elongate the rib b. The
partly made hoe after it has been operated upon as last described is represented in
front elevation in Figure 4 and vertical section in Figure 5, the plated or body
part being marked d. I take the plated hoo Figures 4 and 5, and raise tho
unsteeled part c to a welding heat and operate upon it by dies and pressure or by
stamping or rolling so as to form the eye of the hoe as represented in Figure 6,
where the eye of the hoe made from the part c is marked e. The plate & having
been trimmed, the hoe is finished in the ordinary way. Figure 7 represents in
front elevation; Figure 8 in side elevation and Figure 9 in vertical section a
finished hoe made by the method described.
As the eye of the hoe is formed after the plating out of the body there is nothing
in the subsequent operations to interfere with or injure the shape of the eye and
hence the advantages of my method of manufacture hereinbefore pointed out, are
obtained.

page_text: In manufacturing adzes and mattocks according to my invention I adopt in all
essential respects the method of manufacture described with reference to a hoo;
that is, I plate or draw out the body of the article prior to the formation of
the eye.
Having now described the nature of my invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my invention.―
The improvements in the manufacture of hoes, adzes and mattocks herein before
described and illustrated in the accompanying Drawing; that is to say, making a
depression in the blank or "mould "between that part from which the eye is to bo
made and that part from which the body is to be made and at the same time
forming the rib which joins the eye; next plating or drawing out the steeled part
of the mould to form the body and afterwards forming the eye from the unstecled
part of the mould substantially as and for the purpose described and illustrated.
In witness whereof I the said Robert Perks Yates have hereunto set my
hand and seal this Twelfth day of October in the year of our Lord
one thousand eight hundred and eighty two.
Witness,
RICHARD SKERRETT,

Birmingham.
