Improvements in Rolls for Rolling Carriage Axles and Railway
Buffer Shanks.
We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford, Manu-
facturers, do hereby declare the nature of this invention to be as follows:--
Our invention has reference to rolls for rolling carriage axles and railway buffer
shanks of the kind commonly called sectional or back action rolls, that is, a pair of
rolls having recesses or cut away parts made in their peripheries between which
cut away parts the bar to be fashioned is introduced, a stop limiting the distance
to which the bar is inserted between the rolls, the bar being fashioned by the back
action of the rolls and returned to the workman at the front of the rolls.
Our improvements are especially applicable to the rolls described and represented
in the Specifications of Letters Patents No. 13123 year 1889 and No. 12797 year 1892,
but our improvements are applicable to segmental or back action rolls for rolling
carriage axles and railway buffer shanks generally.
Our invention consists of the following improvements in the gearing of the said
rolls. The two rolls are ordinarily geared together by gearing external to the necks
and bearings of the rolls. According to our invention we use in addition to the
ordinary driving gearing, supplementary gearing of the kind hereinafter described,
whereby the rolls are so engaged or locked together that all tendency in the rolls
to slip or advance one on the other is counteracted and the rolls consequently
rotate in perfect unison and the production of waste bars or articles reduced to a
minimum.
In carrying our invention into effect we place on one end or on both ends of the
barrel of each roll, that is, at the part between the neck and the acting or grooved
part of the roll, a toothed wheel, the said toothed wheels being either keyed on the
barrels or made solid or in one piece with the barrels.
The said toothed wheels on the barrels of the rolls gear together and by their
engagement so lock or secure the two rolls together that their slipping is prevented.
In place of or in addition to the toothed wheels at the end or ends of the barrels
of the segmental rolls, toothed wheels may be cast or fixed at the middles of the
segmental rolls.
The toothed wheels on the barrels and middles of the rolls may be used for directly
driving the rolls instead of being used in conjunction with the ordinary driving
gearing.
The locking or driving toothed wheels on the barrels of the rolls may either be
used with rolls three high, or with a pair of rolls.

We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford, Manu-
facturers, 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 has reference to rolls for rolling carriage axles and railway buffer
shanks of the kind commonly called sectional or back action rolls, that is, a pair
of rolls having recesses or cut away parts made in their peripheries between which
cut away parts the bar to be fashioned is introduced, a stop limiting the distance
to which the bar is inserted between the rolls, the bar being fashioned by the back
action of the rolls and returned to the workman at the front of the rolls."
Our improvements are especially applicable to the rolls described and represented
in the Specifications of Letters Patents No. 13123 year 1889 and No. 12797 year 1892,
but our improvements are applicable to segmental or back action rolls for rolling
carriage axles and railway buffer shanks generally.
Our invention consists of the following improvements in the gearing of the said
rolls. The two rolls are ordinarily geared together by gearing external to the necks
and bearings of the rolls. According to our invention we use in addition to the
ordinary driving gearing, supplementary gearing of the kind hereinafter described,
whereby the rolls are so engaged or locked together that all tendency in the rolls to
slip or advance one on the other is counteracted and the rolls consequently rotate
in perfect unison and the production of waste bars or articles reduced to a minimum.
In carrying our invention into effect we place on one end or on both ends of the
barrel of each roll, that is, at the part between the neck and the acting or grooved
part of the roll, a toothed wheel, the said toothed wheels being either keyed on the
barrels or made solid or in one piece with the barrels.
The said toothed wheels on the barrels of the rolls gear together and by their
engagement so lock or secure the two rolls together that their slipping is prevented.
In place of or in addition to the toothed wheels at the end or ends of the barrels
of the segmental rolls, toothed wheels may be cast or fixed at the middles of the
segmental rolls.
The toothed wheels on the end or ends of the barrels or middles of the barrels of
the rolls, may be used for directly driving the rolls instead of being used in con-
junction with the ordinary driving gearing.
Figure 1 of the accompanying drawings represents in elevation, partly in longi-
tudinal section and Figure 2 in cross section, through the gearing at one end of the
rolls, a pair of sectional or back action grooved rolls for shaping or fashioning
carriage axles, the said back action rolls being geared together according to our
invention. The said back action rolls Figures 1 and 2 have recesses or cut away
parts made in their peripheries (indicated in dotted lines in Figure 2) between
which cut away parts the bar to be fashioned is introduced, a stop limiting the
distance to which the bar is inserted between the rolls, the bar being fashioned by
the back action of the rolls and returned to the workman at the front of the rolls as
is particularly described in the Complete Specification of Letters Patent No. 12797
year 1892 before referred to; Figure 5 represents an elevation of a finished carriage
axle which has been fashioned by the operation of the back action rolls.
a, 6 are the back action grooved rolls and c, d are the stop plates at the back of
the cut away parts e, f of the rolls. The two rolls a, b are geared together at each
end of the barrels by the pair of gearing or toothed wheels g, h; the said wheels

page_text: being made solid to or cast in one piece with the roll. The said gearing or toothed
wheels g, h; g, h are situated within the housings i, i of the rolls and by their use,
the said rolls are so engaged or locked together that all tendency in them to slip
or advance upon one another is counteracted and great accuracy in the rolling
secured and the production of waste articles reduced to a minimum.
Instead of making the gearing wheels solid to the barrels of the rolls as
represented in Figures 1 and 2 they may be made separately and keyed on the
necks of the rolls within the housings i as illustrated in Figures 3 and 4, where
the separate gearing wheels are marked g², g² and the keys of the same are
marked k, k.
Figure 6 represents in elevation, partly in longitudinal section, and Figure 7 in
cross section, through the gearing wheels, a pair of back action grooved rolls for
rolling or fashioning railway buffer shanks, the said rolls being geared together
according to our invention, the gearing wheels at each end of the barrels of the
rolls being made solid to or cast with the said barrels of the rolls.
Figures 8 and 9 represent a pair of back action grooved rolls for fashioning rail-
way buffer shanks in which rolls the gearing wheels are made separate and keyed
to the necks of the rolls adjacent to the barrels.
Figure 10 represents a railway buffer shank which has been fashioned by the
operation of the rolls as described in the Complete Specification of Letters Patent
No. 13123 year 1889.
The parts of the buffer shank rolls Figures 6, 7, 8 and 9 are marked with the
same letters of reference as corresponding parts of the axle rolls Figures 1, 2, 3 and 4.
Although we have represented the back action rolls as geared together by gearing
wheels at each end of the barrels of the rolls, yet gearing wheels at one end of each
barrel or at the middle of each barrel may be employed, and the gearing wheels
described and represented may either be used for directly driving the rolls or be
used in conjunction with the ordinary driving gearing.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that we
claim as our invention:-
The improvements in sectional or back action grooved rolls for rolling carriage
axles and railway buffer shanks hereinbefore described and illustrated in the
accompanying drawings, that is to say, gearing and locking together the barrels of
a pair of back action grooved rolls for the purposes described by means of toothed
gearing or gearing wheels applied to one end or to both ends or to the middle of
each of the barrels of the rolls the said gearing and locking wheels being situated
within the housings of the rolls and being made either solid with or keyed on the
barrels of the rolls substantially as described and illustrated.
