A New or Improved Guide for Guiding Rods of Metal in Rolling
Mills or Machinery.
We JOHN WILLIAMS, Junior of Rogerstone Bassaley, in the County of
Monmouth, Steel Works Manager and Enoou PURSALL of Rogerstone aforesaid,
Roll-Turner do heroby declare the nature of this invention to be as follows :-
Our invention consists of a guide for automatically guiding a rod of metal from
the groove in one pair of rolls into the groove in which it has next to be operated
in another pair of rolls, the parts of which guide are constructed and combined and
operate in the manner hereinafter described.
The said guide is especially suited for use in rolling machinery employed in the
rolling of heated bars of iron and steel into hoops and into rods for the manufacture
of nails and screw blanks but may also be applied to rolls for rolling rods of other
metals and alloys.
Guides made according to our invention may be used in connection with
three-high rolls or with pairs of rolls or in connection with three-high and a
pair of rolls.
The guide constituting our invention consists of an iron or steel tube having the
figure of the letter U; that is, it consists of two parallel branches connected by B
semi-circular part. One end of the guide is expanded and the other end is
contracted. The rod under treatment is delivered from the grooved rolls by which
it has been operated upon into the wide or expanded end of the guide, the other
contracted end of the guide accurately directing the rod into the groove of the rolls
by which it has next to be operated upon..
The parallel branches or portions of the guide are simple tubes but the semi-
circular part is not simply tubular; it consists of a curved piece having the figure
of an inverted trough, which inverted trough is hinged to the ends of the parallel
branches and in its normal position rests on a fixed plate in the same plane as the
lower surfaces of the parallel branches thus constituting a continuation of the
tubular branches. The object of making the upper part of the curved portion of
the guide capable of turning on hinges and of rising out of the plane of the other
part of the guide, is to permit of the lengthening of the rod under operation
without affecting the action of the guide. The rod lengthens as it is reduced
in diameter and the bow formed between its exit from one groove and its entrance
into another gradually increasing in size it is necessary that the upper part of
the curved part of the guide should rise so as to allow of the lengthening of the
loop which is supported on the fixed plate. In order that the upper portion
of the curved part of the guide may be raised automatically as the loop lengthens
the outer side of the inverted trough is inclined and the lengthening loop pressing
against or under the inclined side the trough shaped part of the guide is raised.
When the rod has

left the first groove the loop contracts and the raised part of the guide falls by
its own weight.
We employ the improved guide described principally to guide the rod operated
upon from the groove in one pair of rolls to a groove at a lower level in
another pair of rolls in which case the guide is inclined into a plane passing through
the two grooves but we do not limit ourselves to any particular method of using
the guide.

A New or Improved Guide for Guiding Rods of Metal in Rolling
Mills or Machinery.
We, JOHN WILLIAMS Junior of Rogerstone, Bassaley in the County of
Monmouth, Steel Works Manager, and ENOCH PURSALL, of Rogerstone, aforesaid,
Roll Turner, do hereby declare the nature of our invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
Our invention consists of a guide for automatically guiding a rod of metal from
the groove in one pair of rolls into the groove in which it has next to be operated
in another pair of rolls, the parts of which guide are constructed and combined and
operate in the manner hereinafter described.
The said guide is especially suited for use in rolling machinery employed in the
rolling of heated bars of iron and steel into hoops and into rods for the manufacture
of nails and screw blanks but may also be applied to rolls for rolling rods of other
metals and alloys.
Guides made according to our invention may be used in connection with
three-high rolls or with pairs of rolls or in connection with three-high and a
pair of rolls.
'
The guide constituting our invention consists of an iron or steel tube having the
figure of the letter U; that is, it consists of two parallel branches connected by a
semi-circular part. One end of the guide is expanded and the other end is
contracted. The rod under treatment is delivered from the grooved rolls by which
it has been operated upon into the wide or expanded end of the guide, the other
contracted end of the guide accurately directing the rod into the groove of the
rolls by which it has next to be operated upon.
The parallel branches or portions of the guide are simple tubes but the semi-
circular part is not simply tubular; it consists of a curved piece having the figure
of an inverted trough which inverted trough is hinged to the ends of the parallel
branches and in its normal position rests on a fixed plate in the same plane as the
lower surfaces of the parallel branches, thus constituting a continuation of the
tubular branches. The object of making the upper part of the curved portion of
the guide capable of turning on hinges and of rising out of the plane of the other
part of the guide, is to permit of the lengthening of the rod under operation
without affecting the action of the guide. The rod lengthens as it is reduced
in diameter and the how formed between its exit from one groove and its entrance
into another gradually increasing in size it is necessary that the upper part of
the curved part of the guide should rise so as to allow of the lengthening of the
loop which is supported on the fixed plate. In order that the upper portion
of the curved part of the guide may be raised automatically as the loop lengthens
the outer side of the inverted trough is inclined and the lengthening loop pressing
against or under the inclined side the trough shaped part of the guide is raised
and permits the loop to lengthen itself without obstruction. When the rod has
left the first groove the loop contracts and the raised part of the guide falls by
its own weight.
'
We employ the improved guide described principally to guide the rod operated
upon from the groove in one pair of rolls to a groove at a lower level in
another pair of rolls in which case the guide is inclined into a plane passing through
the two grooves; but we do not limit ourselves to any particular method of using
the guide.
We will now describe with reference to the accompanying drawings the manner
in which our invention is to be performed.
Figure 1 represents in side elevation, Figure 2 in end elevation and Figure 3 in

page_text: plan our new or improved game in conjunction with a set of three:migh cylindrical
rolls for rolling hoops.
Figure 4 represents in end elevation; Figure 5 in plan and Figure 6 in side
elevation, partly in longitudinal section, the said guide without the rolls, drawn to
a larger scale; Figure 7 represents one of the guide tubes which is fitted in one of
the branches of our improved guide as hereinafter described.
The same letters of reference indicate the same parts in the several figures of the
drawings.
Our improved guide consists of an iron or steel tube having the general figure of
the letter U.
The principal parts of which the said U shaped guide are composed are
marked a b and c, the parts a and b consisting of parallel tubular branches connected
together by the semi-circular partc which is hinged at d, d to the ends of the
brauches a, b. The parallel branches a, b of the guide are simple tubes, but the
semi-circular hinged part chas the figure in cross section of an inverted trough
(see the enlarged view Figure 6) constituting a continuation of the tubular
branches a, b. The hinged semi-circular part c of the guide is weighted at e
and rests in ite normal position on the curved fixed plate situated in the same
plane as the lower surfaces of the parallel branches ab of the guide (see
Figures 5 and 6). The inner side of the hinged part of tho guide is inclined
for the purpose hereinafter described. In the expanded end of the branch a of
the shaped guide, a guide tube g is fitted (shown separately in Figure 7) the
nearly shaped end of the guide passing between the upper and middle rolls h, i.
for conducting the heated rod from the rolls to our improved guide, and a nearly
similar guide tube is fitted in the end of the other branch of the guide for
conducting the heated rod passed through our improved guide to the lower pair of
rolls i, k. The guide tube at the upper and lower faces of its V shaped end has
sliding dovetailed pieces g', g' which, should the guide tube be advanced too near
the rolls, are acted upon by the said rolls and the guide thereby prevented from
being drawn between the rolls.
When our improved guide is used with three high rolls, us represented in the
drawing, it is supported obliquely upon the inclined bracket or stay m at the back
of the rolls (see Figure 2) so that the upper branch a and its guide tube g are
situated opposite the groove between the upper pair of rolls h, i and the lower
branch and its guide tubo are situated opposite the groove between the
lower pair of rolls (see Figure 1). When the guide is used with pairs of rolls
on the same level it is situated horizontally, that is, is not inclined as represented
in Figure 2.
.
It will be seen by an examination of the drawing that the curved or semi-
circular hinged part c of the guide is capable of rising out of the plane of the
tubular parts or branches a, b the said semi-circular part when unsupported
falling into its normal position on the plate by its weight assisted by the
weighted arm e.
The inner edge of the hinged part c of the guide is furnished with a guard n to
prevent the heated rod slipping up to the rolls in case of buckling.
As the loop of the rod passing through the guide lengthens during the rolling
operation, the trough shaped hinged part is lifted automatically by the said
lengthened loop pressing against or under the inner inclined side of the said part o
thereby permitting of the loop to lengthen itself without obstruction the loop as it
lengthens passing outside the raised hinged part c of the guide and being supported
on the curved plate f. When the heated rod has left the upper pair of rolls h, i
the loop contracts and the raised hinged part c of the guide falls by its own weight.
As the edge of the hinged part c bears upon the loop of the heated rod; after the
said part c has been lifted, in order to prevent the scraping and consequent wear
and friction on the edge of the said part c we fix an anti-friction roller
part of the hinged portion of the guide which bears upon the loop. The scraping
and friction referred to are thereby prevented.
P at that

We will now describe the general action of the guide.
The heated rod passing from the top pair of rolls h, i is conducted to the lower
pair of rolls ik by the U shaped guide and its prolonged parallel branches.
Before the heated rod passes into the lower pair of rolls the loop formed by the
heated rod in passing through, the guide does not lift the weighted trough shaped
part of the guide, but on the heated rod passing between the lower pair of
rolls, its loop lengthens by the action of the rolls, and the said lengthened loop
by pressing against the inclined inner face of the curved part c. of the guide lifts it,
the gradually increasing loop being now supported on the plate f external to the
said lifted curved part c. On the rod leaving the top pair of rolls its loop contracts
and the raised part c of the guide falls on the plate as represented in the
drawing.
We use our improved guide in connection with a set of three high rolls and a
pair of rolls and with pairs of rolls for the purpose of conducting the heated rod
from one pair of rolls to another pair of rolls by which it is to be operated upon
substantially as herein before described and illustrated in the accompanying drawings
with respect to a set of three high rolls.
Having now particularly described and ascertained the nature of our inven-
tion and the manner of performing the same we declare that we claim as our
invention
The new or improved guide for automatically guiding a heated rod of metal
from the groove in or between one pair of rolls into the groove in or between
another pair of rolls in rolling mills or machinery, the said guide being constructed.
and used substantially as hereinbefore described and illustrated in the accompanying
drawings; that is to say a guide for the purpose described consisting essentially of
an iron or steel tube having the shape of the letter U, the curved or semi-circular
part of the guide baving the figure of an inverted trough supported upon a flat
plate under it and being hinged to the ends of the tubular parallel branches of the
guide, the said curved or semi-circular part of the guide being lifted out of
the plane of the other parts, by the pressure of the enlarging loop of the rod
upon the inclined interior of the hinged part of the guide substantially as described
and illustrated..
