Improvements in Piling Iron and Steel Bars for Rolling.
I, PHILIP ROBINSON, of 158, Holly Lane, Smethwick, Staffordshire, Roll
Turner, do hereby declare the nature of this invention to be as follows:-
:-
This invention consists of the herein described improvements in piling iron and
steel bars for rolling. Heretofore the crop ends and scrap pieces of round square
and other bars of small section have been used in box piles, the sides top and
bottom of the pile being formed of puddle bars roiled to such a section that they
will engage together and enclose the short pieces of round square and other scrap
bars inside. These box piles however are not satisfactory as the small section bars
inside the pile being of smaller area than the outside bars are often burnt in the
furnace; and when the scrap bars are round there are certain open spaces
between the bars so that the pile is not solid and is crushed and distorted in
passing through the rolls and the finished bar often has many spilley places and
defects in it. My invention is particularly designed to utilise scrap pieces of iron
and steel of round section but can also be applied to using up scrap pieces of
bars of other sections such as half round squares and others.
In carrying out my invention I roll puddle bars of the same width as the
required pile and with longitudinal half round or other section grooves in one
or both faces of the puddle bar these grooves being of the proper size to receive
the scrap ends or pieces of round or other section bars which are to be used up.
in forming the pile the puddle bars are cut to the length of the pile and the
short scrap ends of the round or other section bars are laid in the grooves between
two of the puddle bars thus forming a practically solid bar and as many of these
are laid together on the top of each other as will form the required pile. It will
be seen that a pile formed as above described is practically solid and that there
are no spaces round the round bars along which the flames can play and therefore
the short round pieces of iron or steel cannot become burnt but the pile will be
uniformly heated throughout.

Improvements in Piling Iron and Steel Bars for Rolling:
I, PHILIP ROBINSON, of 158, Holly Lane, Smethwick, Staffordshire, Roll
Tuner, do hereby declare the nature of this invention and in what manner the
[Price 8d.]

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention consists of the herein described improvements in piling iron and
steel bars for rolling. Heretofore the crop ends and scrap pieces of round square
and other bars of small section have been used in box piles, the sides top and
bottom of the pile being formed of puddle bars rolled to such a section that they
will engage together and enclose the short pieces of round square and other scrap
bars inside. These box piles however are not satisfactory as the small section bars
inside the pile being of smaller area than the outside bars are often burnt in the
furnace; and when the scrap bars are round there are certain open spaces
between the bars so that the pile is not solid and is crushed and distorted in
passing through the rolls and the finished bar often has many spilley places and
defects in it. My invention. is particularly designed to utilise scrap pieces of iron
and steel of round section but can also be applied to using scrap pieces of
bars of other sections such as half round square and others.
I will describe my invention by referring to the accompanying drawing on which
Fig. 1 is a cross section of an iron pile or a composite iron and steel pile formed
in accordance with this invention; Fig. 2 shews separately in cross section the
puddle bars used in the pile represented by Fig. 1; and Figs. 3 and 4 are cross
sections of other piles formed in accordance with this invention.
In carrying out my invention I roll puddle bars of the same width as the
required pile and with longitudinal half round or other section grooves in one
or both faces of the puddle bar these grooves being of the proper size to receive
the scrap ends or pieces of round or other section bars which are to be used
up and which are placed in the grooves between the bars.
In the pile represented by Fig. 1 four puddle bars are used marked respec-
tively A A B 1. The bars A A² are both of the same section made with three
longitudinal grooves marked respectively a a² a in one face only. The bars B 13º
are also both of the same section each bar having three half round grooves 61 62 63
rolled on one face corresponding with the grooves a¹ a a³ in the ouside bars A¹A²
to receive the round scrap ends or pieces of iron or steel Û and also having two
half round grooves b b rolled in the other side of the bar to receive the round
scrap ends or pieces or iron or steel D). In forming the pile the puddle
bars A A B B12 are cut to the length of the pile and the short scrap ends or pieces
of round bars CD) are laid in the grooves between the puddle bars as in Fig. 1
thus forming a practically solid bar and as many of these puddle bars and scrap
ends or pieces are laid together on the top of each other as will form the required
pile. It will be seen that the pile formed as above described and illustrated in
Fig. 1 is practically solid and there are no spaces round the round bars CD along
which the flames can play and therefore the short pieces of iron or steel CD
cannot become burnt in the furnace but the pile will be uniformly heated through-
out.
Morcover by each of the short ends or pieces CD engaging with two puddle
bars the latter are prevented from twisting and, getting askew whilst the pile
is being placed in or removed from the furnace or whilst being turned over therein.
Fig. 3 shows a slightly modified arrangement of my invention formed of six
puddle bars marked respectively A' A² A³ A A5 A6 each having half round grooves
(or they may be other shaped grooves) rolled in only one side of the bar but this
arrangement is not so good as that herein before described and illustrated by Fig. 1
as owing to the grooves being only on one side of the puddle bars the proportion of
scrap ends or short pieces of round bars used up in the pile is smaller than in the
arrangement shewn by Figs. 1 and 2.
In the pile shewn in cross section by Fig. 4 the grooves in the puddle
bars A¹ A B¹ B2 are V-shaped so as to receive the scrap ends or short pieces of
square iron or steel bars C which lie in the said grooves.
It will be understood that the number of puddle bars in the pile and also the
number of grooves in the puddle bars to receive the scrap ends or short bars C

page_text: will be varied according to the size of the required pile and the scrap ends or short
bars C which are to be used up.
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:-
-
1. In the manufacture of rolled iron bars, forming the pile of layers of grooved
puddle bars with scrap ends or short pieces of iron bars lying between the puddle
bars and filling up the said grooves in the same substantially as set forth and
illustrated.
2. In the manufacture of rolled composite iron and steel bars, forming the pile
of layers of grooved puddle bars with scrap ends or short pieces of steel bars
lying between the puddle bars and filling up the said grooves in the same
substantially as set forth and illustrated.
Dated this 15th day of November 1899.
