Bars and other kinds of Taper Bars and articles of Iron or Steel.
We, JABEZ LONES and EDWARD HOLDEN trading as LONES, VERNON and HOLDEN of
Sandwell Iron and Axle Works, Smethwick in the County of Stafford, Manufacturers
do hereby declare the nature of this Invention to be as follows:—
The rolls ordinarily employed for rolling taper bars, spoke bars, knee bars and other
kinds of taper bars and articles of iron or steel are driven by the usual gearing
external to the necks and wobblers of the rolls. By this method of gearing together
the two rolls, they have a tendency to slip or to advance one on the other thereby
producing imperfect bars or articles.
The object of our invention is to effectually prevent the slipping of the rolls by.
using in addition to the ordinary driving gearing supplementary gearing of the kind
hereinafter described, whereby the said rolls are so engaged or locked together that
they can only rotate in perfect unison and the production of waste bars or articles
thereby reduced to a minimum.
According to our invention we place on the barrel of each roll, that is, the part
between one of the necks of the roll and the acting or grooved part of the roll, a
toothed wheel having preferably square or flat teeth, the said toothed wheel being
keyed on or made solid or in one piece with the roll. The said supplementary
toothed wheels on the barrels of the two rolls gear together and by their engagement
so lock or secure the two rolls together that their rotation is perfectly uniform and
their slipping prevented.
The additional locking toothed wheels may be on either side of the barrel parts of
the rolls or the said locking toothed wheels may be employed on each side of the
barrel parts of the rolls.
Our improvements may be applied to three high rolls as well as to a pair of rolls.
Improvements in Rolls for Rolling Taper Bars, Spoke Bars, Knee
Bars and other kinds of Taper Bars and articles of Iron or Steel.
We, JABEZ LONES and EDWARD HOLDEN, trading as LONES, VERNON and HOLDEN,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford
Manufacturers, do hereby declare the nature of our invention and in what manner

page_text: the same is to be performed to be particularly described and ascertained in and by
the following statement ;-
The rolls ordinarily employed for rolling taper bars, spoke bars, knee bars and
other kinds of taper bars and bars of irregular sections and articles of iron or steel
are driven by the usual gearing external to the necks and wobblers of the rolls. By
this method of gearing together the two rolls, they have a tendency to slip or advance
one on the other, thereby producing imperfect bars or articles.
The object of our invention is to effectually prevent the slipping of the rolls by
using in addition to the ordinary driving gearing, supplementary gearing of the kind
hereinafter described, whereby the said rolls are so engaged or locked together that
they can only rotate in perfect unison and the production of waste bars or articles
thereby reduced to a minimum.
According to our invention we, place on the barrel of each roll, that is, the part
between one of the necks of the roll and the acting or grooved part of the roll, a
toothed wheel having either square or flat teeth or V shaped or oblique teeth, the
said toothed wheel being keyed on or made solid or in one piece with the roll. The
said supplementary toothed wheels on the barrels of the two rolls gear together and
by their engagement so lock or secure the two rolls together that their rotation is
perfectly uniform and their slipping prevented.
The additional locking toothed wheels may be on either side of the barrel parts of
the rolls or the said locking toothed wheels may be employed on each side of the
barrel parts of the rolls, or in the middle of the barrels of the rolls.
Our improvements may be applied to three high rolls as well as to a pair of rolls.
Figure 1 of the accompanying Drawings represents in elevation partly in
longitudinal section a pair of grooved rolls to which supplementary toothed gearing,
according to our invention, is applied, and Figure 2 is a cross section of the rolls
taken through the said supplementary toothed gearing.
a, b are the barrels containing the acting grooves of the pair of rolls and c, d are
supplementary toothed wheels or gearing made solid or in one piece with the
barrels a, b; the said toothed wheels c, d gearing together and so locking the two
rolls a, b together that their slipping is effectually prevented during the operation of
the rolls. By thus locking together the barrels of the rolls the acting faces of the
grooves of one roll are made to work exactly opposite or are brought coincident with
the acting faces of the corresponding grooves in the other roll and the production of
waste bars or articles thereby prevented. The housings in which the necks of the
rolls work are indicated in dotted lines and are marked e, f in Figure 1, the toothed
wheels c, d being situated inside the housing f as represented.
Figure 3 represents in elevation partly in longitudinal section a pair of grooved
rolls in which supplementary gearing or toothed wheels are situated at both ends of
the barrels of the rolls instead of at one end only as represented in Figures 1 and 2.
The gearing toothed wheels at one end of the rolls are marked g, h and those at the
other end of the rolls are marked i,k. The pairs of toothed wheels g, h and i, k are
made solid or in one piece with the barrels of the rolls a, b and are situated within
the housings e, f in which the necks of the rolls work.
Instead of making the supplementary gearing or toothed locking wheels either at
one or at both ends of the barrels of the rolls solid with the barrels of the said rolls,
the said toothed wheels may be made separate from and keyed on the barrels as
illustrated in longitudinal section in Figure 4 and cross section in Figure 5 where the
separate toothed wheel keyed on the barrel a is marked l. The neck of the roll is
marked a².
Figure 6 represents in elevation three high grooved rolls to which supplementary
toothed or locking wheels at both ends of the rolls and situated within the
housings e, f of the rolls, are applied. The three high grooved rolls are marked m, n, p
and the gearing and locking wheels at one end of the barrels of the rolls are
marked m², n², p2 and the gearing or locking wheels at the other end of the barrels
of the rolls are marked m³, n³, p³ the said toothed wheels m², n², p² and m³ n³ p³
being made solid with or keyed on the barrels of the rolls,

page_text: Although we prefer to apply the gearing or locking wheels either to one end or to
both ends of the barrels of the rolls, yet the gearing or locking wheels may be applied
to the middle of the barrels of the rolls.
We make the grooves and the acting parts of the rolls either when using a pair, or
three high rolls, of the shapes proper to effect the rolling or fashioning of taper bars,
spoke bars, knee bars and other kinds of taper bars and bars of irregular sections and
other articles of iron or steel operated upon by the said rolls.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that we claim as our
invention
The improvements in rolls for rolling taper bars, spoke bars, knee bars and other
kinds of taper bars and bars of irregular sections and articles of iron or steel
hereinbefore described and illustrated in the accompanying Drawings, that is to say,
gearing and locking together the barrels of pairs of grooved rolls or three high
grooved rolls by means of supplementary toothed gearing or gearing wheels applied
to one end or to both ends or to the middle of the barrels of the rolls and gearing the
said rolls together, the said supplementary gearing or locking toothed wheels being
situated within the housings of the rolls and either made solid with or keyed on the
said barrels for the purposes and substantially as described and illustrated.
