I JOHN THOMSON KING of 4 Clayton Square Liverpool in the county of Lancaster,
Patent Agent, 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 :-
In rolling metal rods as now commonly practised, it is customary to employ a series
of trains of rolls set with their axis in line with each other and to pass the metal back
and forth between them.
As the metal is reduced in diameter and increases in length, it elongates in the
form of loops extending from the delivery side of one pair of rolls to the receiving
side of the next succeeding pair of the series, and as the loops elongate there is always
difficulty in controlling them and preventing their kinking, especially so when it is
attempted to roll more than one rod at once in a single mill. For this purpose, it has
been usual to employ boys who stand with hooks opposite to the rolls and guide the
loop with a view to prevent it from kinking or injuring the workmen. The work of
these boys is very dangerous and requires the closest attention, while the wages paid
to them are high. The least neglect on their part is apt to cause the kinking of the
rod, and when this happens, the delay in its passage through the mill chills the metal
and unfits it for use, necessitating the cutting of it into pieces for scrap. In order to
diminish these evils and to guide the metal loop as it emerges, I have devised my
present invention. It consists in a guide trough or channel extending from the
delivery side of a pair of two trains of rolls, and in a direction transverse to their
axis, the trough or channel being open at the side or top, so that as the loop elongates,
that branch of it which is next to the first pair of rolls shall travel within the trough
or channel, and shall be guided thereby and shall thus be prevented from spreading
over the floor of the mill. Two or more loops may be successfully guided at once by
the trough, and the mill may be operated with little labour and with great security to
the workmen.

page_text: My invention is illustrated in the accompanying drawings in which fig. 1 is a plan
view of two adjacent pairs of rolls, and the guide trough extending transversely to one
pair, and fig. 2 is a sectional cross section on the line a --- of fig. 1.
In the drawing, a and bare the rolls, c is the guide trough, and d is the clongating
metal loop which travels in the direction of the arrow.
The guide trough is made tubular in cross section with an opening at the side for
the passage of the wire loop, but I do not limit my invention thereto, since it may
be made in the form of a trough open at the top or of any other convenient
shape.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
In a rod mill, wherein the rod emerges from one pair of rolls and passes to the
next pair in a reflexed course forming a loop, an open guide extending from the rolls,
and guiding a branch of the loop substantially as described.
Dated this 16th day of May 1888.
