PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Hammered Scythes and
similar Articles.
We, WILLIAM JAMES BINGHAM of Norton Woodseats near Sheffield in the
County of Derby Manufacturer, and THOMAS DODDS of Clough Works, Leadmill
Road Sheffield in the County of York Forgeman do hereby declare the nature of
this invention to be as follows:-
:―
Our invention relates to improvements in the forging of scythes, hay knives and
o: her similar articles. In the manufacture of scythes and hay knives the mode of
manufacture at present in common use consists of the following:-Two pieces
of flat iron are cut into required lengths; these are then drawn out separately
under a hammer driven by water or steam or other power to form a bevelled shape.
A piece of steel is then taken & likewise drawn out to form a bevelled shape. The
piece of shaped steel is then placed between the two pieces of iron and heated in a
furnace and then welded together forming what is known as a mould which is
afterwards plated out to the shape and size required.
By our improved method we propose to obviate the necessity for separately
drawing the pieces of iron and steel and forming the mould, by taking a long bar
composed of iron and steel which has been previously rolled or hammered preferably
to a bevelled section but it may also be used flat. The steel is rolled or hammered
on to either side of the bar or it can be rolled or hammered to form a thin layer
running up the centre of the bar. We then cut the bar of iron and steel so
prepared into such lengths as may be required, these lengths taking the place of
the moulds formed by the method as at present in common use and we then plate
them out under a hammer driven by water or steam or other power in the manner
as at present in common use, to the shape and size required.
Dated this Twenty-fourth day of February 1894.

Improvements in the Manufacture of Hammered Scythes and
similar Articles.
We WILLIAM JAMES BINGHAM of Norton Woodseats near Sheffield in the
County of Derby Manufacturer and THOMAS DODDS of Clough Works Leadmill
Road Sheffield in the County of York Forgeman do hereby declare the nature of
this iuvention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to the manufacture of hammered scythes and similar
articles and consists particularly in the manner of constructing the composite steel
and iron bars from which these articles are made.
The ordinary manner of producing these bars is as follows:-Two pieces of the
requisite length of flat iron are hammered out so as to take a bevelled or wedge
shape in transverse section and between these is placed a suitably shaped bar of

page_text: steel, the three being welded together so as to form what is known as a "mould'
and subsequently rolled pressed or hammered to the desired shape.
"
By our invention we make each of the bars of one piece of iron and one piece of
steel only.
The invention will be best understood by reference to the accompanying
drawings in which :-
Figures 1, 2 and 3 are sections showing three different ways of forming the
composite steel and iron bars and
Figures 4 and 5 show respectively a scythe and a hay-knife which may be
manufactured from bars such as shown in Figures 1, 2 and 3.
Like letters indicate like parts throughout the drawings.
The arrangement shown in Figure 1 comprises an iron bar A one side of which
is rabbetted as at A¹ for receiving the steel bar B the two being subsequently
welded together to form a single bar which may be fashioned into any desired
blade or tool.
In Figure 2 the iron bar A instead of being formed with a rectangular rabbet as
in Figure 1 is bevelled at one of its corners or faces, and the steel bar B, bevelled
to correspond, is welded to the bar A at this part.
In Figure 3 the iron bar A is formed with a tapering recess A' into which is
fitted and subsequently welded a correspondingly tapered steel bar B. If desired
the recess A' and steel bar B instead of being taper as shown in Figure 3 may be
of rectangular or other form.
The composite steel and iron bars produced as before described though specially.
applicable to the manufacture of scythes, hay knives or the like may also be used
for other purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A composite bar of iron and steel formed of only one bar of iron and one bar
of steel welded together substantially as described and illustrated in Figure 1,
Figure 2 or Figure 3 of the accompanying drawings.
2. A scythe hay knife or similar article manufactured from a composite bar of
iron and steel formed of only one bar of iron and one bar of steel welded together
substantially as described and illustrated in the accompanying drawings.
Dated this 19th day of February 1895.
