"IMPROVE-
MENTS IN ROLLING-MILLS OR APPARATUS FOR ROLLING METALLIC RODS OR
BARS."
This Invention relates to rolling mills or apparatus for rolling metallic rods or
bars.
In rolling-mills of ordinary construction the blooms or billets are passed forwards
and backwards through a train of rolls, consisting of several pairs or sets of rolla
until the said blooms or billets are reduced to the required shape and size, cach
pair or set of rolls working in housings fixed in a bed plate common to each, one
pair or set of rolls working the pair or set of rolls next to it on the same bed plate
by means of coupling boxes and spindles, or other ordinary connections.
By the above arrangement the roughing-down or bolting rolls are driven at the
same speed as the intermediate and finishing rolls. In a rolling mill to which my
improvements are applied, the roughing-down or bolting rolls, or the roughing-
down and one or more pairs or sets of intermediate rolls will be in advance of the
intermediate and finishing rolls on a seperate or the same bed plate, and may thus
be driven at a speed differing from the speed of the second set or intermediate and
finishing rolls; and a hollow box, trough, or pipe of novel construction will be
employed to convey the billet from the first pair or set of rolls to the second pair or
set of rolls, or to any number of pairs or sets of rolls beyond the second pair or set
of rolls, as may be desired or required.
Pipes or troughs of ordinary construction have been employed to conduct the
billet from the back to the front, or from the front to the back of a train of rolls,
the said billet being presented to the next "gate" in the rolls by manual labor, the
said billet having to be turned one fourth part of a revolution by the operator
before being presented to the next "gate" in the rolls; but by my improvements

page_text: the billet is conveyed from one pair of rolls to a second pair of rolls, in advance
thereof and parallel thereto by my improved pipe or trough, and is thereby turned
one fourth part of a revolution during transmission, and fed automatically into the
gate in the second pair of rolls, thus dispensing with hand labor.
The improved hollow box, trough, or pipe is twisted one fourth part of a
revolution, or it has a twisted or rifled groove through it equal to one fourth part
of a revolution, and the opening through it is of the same sectional area throughout,
so that the billet in passing through it is turned one fourth part of a revolution.
In carrying my improvements, into effect, the improved trough is fixed to the
back of the first pair of rolls and to the front of the second pair of rolls, and billets
only are operated upon which are long enough to reach from the first to the second
set of rolls. The heated billet being passed between the first pair of rolls will be
reduced in sectional area thereby and extended in length, and the said rolls will
deliver it into the improved pipe and force it through it, thereby turning it one
fourth part of a revolution, and will deliver it to the second set of rolls.

ALBERT BERRY, of Tinsley, near Rotherham, in the County of York. "IMPROVE-
MENTS IN ROLLING MILLS OR APPARATUS FOR ROLLING METALLIC RODS OR
BARS."
This Invention relates to rolling-mills or apparatus for rolling metallic rods or
bars.
In rolling mills of ordinary construction the blooms or billets are passed forwards
and backwards through a train of rolls, consisting of several pairs or sets of rolls
until the said blooms or billets are reduced to the required shape and size, each pair
or set of rolls working in housings fixed in a bed plate common to each, one pair
or set of rolls working the pair or set of rolls next to it on the saine bed plate by
means of coupling boxes and spindles, or other ordinary connections. By the above
arrangement the roughing-down or bolting rolls are driven at the same speed as
the intermediate and finishing rolls.
In a rolling mill to which my improvements are applied the roughing-down or
bolting rolls, or the roughing-down and one or more pairs or sets of intermediate
rolls will be in advance of the intermediate and finishing rolls, on a separate or the
same bed plate, and may thus be driven at a speed differing from the speed of the
second set or intermediate and finishing rolls, and a hollow box, trough, or pipe of
novel construction will be employed to convey the billet from the first pair or set
of rolls to the second pair or set of rolls, or to any number of pairs or sots of rolls
beyond the second pair or set of rolls, as may be desired or required.
Pipes or troughs of ordinary construction have been employed to conduct the
billet from the back to the front, or from the front to the back of a train of rolls,
the said billet being presented to the next "gate" or groove in the rolls by manual
labor, the said billet having to be turned laterally one fourth part of a revolution
by the operator before being presented to the next "gate" or groove in the rolls:
but by my improvements the billet is conveyed from one pair of rolls to a second pair
of rolls, in advance thereof and parallel thereto by my improved pipe or trough, and
is thereby turned one fourth part of a revolution during transmission, and fed
automatically into the "gate" or groove in the second pair of rolls, thus dispensing
with manual labour.
The improved hollow box, trough, or pipe is twisted one fourth part of a
revolution, or it has a twisted or rifled groove through it equal to one fourth part
of a revolution, and the opening through it is of the saine sectional area throughout,
so that the billet in passing through it is turned laterally one fourth part of a
revolution.
In carrying my improvements into effect, the improved trough is fixed to the
back of the first pair of rolls and to the front of the second pair of rolls, and billets
only are operated upon which are long enough to reach from the first to the second
set of rolls. The heated billet being passed between the first pair of rolls will be
reduced in sectional area thereby and extended in length, and the said rolls will
deliver it into the improved pipe and force it through it, thereby turning it one
fourth part of a revolution, and will deliver it to the second set of rolls auto-
matically, so that it will pass through the second set of rolls which will operate
upon it and deliver it therefrom.
In the accompanying Drawings Fig. 1 is a side view in elevation, and Fig. 2 is a
plan of my improved apparatus applied to two pairs of rolls, and Figs. 3 to 12 show
the details thereof.
A and A' is the first pair of rolls which delivers the billet to the improved pipe,

page_text: box or trough D, and B, B', is the second pair of rolls to which the billet is
delivered by the pipe D, the said billet being turned one fourth part of a revolution
laterally by the said pipe D in its progress from the first pair of rolls A, A¹, to the
second pair of rolls B, B'. To the rolls A, A', is fitted a pipe C secured to the
cramp bar G by the eye bolt J; the front end of the said pipe is tapered, as shown
in Fig. 7, where it enters the improved pipe or trough D. The back end of the
improved pipe D has two wings or projections K, K, by which it is secured by
bolts to the cramp bar G. The improved pipe D is of the form shown in Figs. 1,
2, 3, and 4, and is inade of iron or steel, the parts being held together by set screws
and by the clip E, so that it can be easily taken to pieces; Fig. 5 is a transverso
sectional view of the pipe D as taken through the dotted line Y, Z, and Fig. 6 is a
similar view as taken through the dotted line W, X; Fig. 7 is a side view in
elevation; Fig. 8 is a plan, and Fig. 9 is a front end view of the pipe C.
Fig. 10 is a side view of the clip E; Fig. 11 is a side view in elevation, and
Fig. 12 is a plan of the hollow guard F which is curved at its front end to fit the
rolls B, B, and shaped at its back end to receive and retain the front end of the
improved pipe D. The hollow guard F has a flango L by which it is secured to
the cramp bar H by a bolt or nut.
As a modification of the trough D, as above described, the said trough can be
hinged, as shown at M in Fig. 13, so that it can be opened for the extraction of the
billet in the event of its choking the trough, as may sometimes occur when the
front end of the billet is split.
As a further modification the interior of the improved pipe or trough D can be
angular in cross section instead of rectangular, as shown at D'and D, Figs. 5 and 6.
The details of my Invention can be altered in practise without departing from the
essential features thereof. The improved trough D can be fitted to as many pairs
of rolls (in two trains of rolls) as is desired or required, and in rolling wire or other
forms of iron, steel, or other metals; the trough D will be of the required form in
cross section to suit the form of billet or rod delivered into it by the pair of
rolls, which said billet or rod it will turn laterally one fourth part of a revolution,
and deliver automatically to the pair of rolls in front thereof.
Having now clearly described and ascertained the nature and object of my said
Invention, and the manner in which the saine is or may be performed and carried into
effect, I would observo in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,-
Firstly. Improvements in rolling mills or apparatus for rolling metallic rods or
bars, the essential feature of which is the employment of one or more twisted or
rifled pipes, troughs, or boxes to convey the billet or bar from one pair or set of
rolis to a second pair or set of rolls, and turn the said billet or bar laterally one
fourth part of a revolution.
Secondly. The arrangement of detail parts to carry into practical effect, my
Invention as herein before specified and described in reference to Figs. 1 to 13 of
the accompanying Drawings.
In witness whereof, I, the said Albert Berry, have hereunto sot_my_hand
and seal, this Sixteenth day of October, in the year of our Lord One
thousand eight hundred and eighty.
