Improvements in the Construction or Building Up of the Bars for
the Manufacture of Hoop Iron.,
I, HENRY JONES, of the South Yorkshire Hoop Iron Works, Rotherham in
the County of York, Manufacturer, do hereby declare the nature of my invention
to be as follows:-
This invention has for its object to improve the quality and finish of hoop iron,
and to accomplish this by a novel construction or building up of the constituent
parts of the bar.
I propose therefore to proceed as follows:-I preferably construct the pile in
three sections, the two outside sections being of best iron, and the inner one of soft
steel, or best scrap iron, this combination resulting in a tougher and more fibrous
quality of hoops.
I prefer to roll the inner section of an irregular hexagonal or octagonal form in
its cross section, by I may also employ an oval form, or other variations of such
forms. The outer sections are rectangular outwardly with an interior, shaped so
that when the two are put together they will enclose the inner section. These
sections are put together or "piled," then brought to a suitable welding heat and
rolled down to hoop iron.

COMPLETE SPECIFICATION.
Improvements in the Construction or Building Up of the Bars for
the Manufacture of Hoop Iron.
I HENRY JONES of the South Yorkshire Hoop Iron Works Rotherham, in the
County of York Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has for its object to improve the quality and strength of hoop
iron, and this result is accomplished by a novel arrangement or what is called
building up of the bar or "pile."
I have illustrated this improved and special method of building up the pile in
the annexed sheet of drawings which show the ends of such piles, and they would
also represent transverse sections of such piles.
In carrying out my invention, I construct a pile preferably such as is shown in
Fig. 1. consisting of three sections of material marked A, B, C ; the two outside
sections B, and C, being of best iron rolled to the section shown, and the inner
one A, of soft steel, or best scrap iron rolled down to an irregular hexagonal form
as I find this form gives the best result.
I roll the parts B, and C, with a groove or channel to receive the hexagonal
bar A, and so that it will be entirely enclosed as seen in the drawings, and when so
put together they will not require tying or binding as such piles usually do.
They are then brought to a welding beat in any suitable furnace, and rolled
down into hoop iron, during which process the improved method of piling holds the
P27

page_text: three sections together, causing them to be more perfectly welded and consolidated,
and producing a practically unbreakable hoop iron.
I do not confine myself to the sectional form of the bars A, B, and C, as for
example I may use the sections shown in Figures 2 and 3 of the drawings, or
variations of these, but in all cases I arrange that the inside bar shall be enclosed
by the two outer bars, and preferably that the inner bar shall be reduced at
its edges.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim isį:
1. The improved method of building up the "piles" for rolling into hoop iron
substantially as hereinbefore described and shown in the drawings.
.2. Constructing a pile for the manufacture of hoop iron, in three sections or bars
the two outer bars being of such a shape as to enclose the centre bar which is of
steel or best scrap iron, as hereinbefore described, and substantially as illustrated.
