PROVISIONAL SPECIFICATION.
Improvements in Machines for Mangling, Calendering, or Finishing
Woven Fabrics.
We, WILLIAM ROBERTSON, and JAMES GUTHRIE ORCHAR, of Wallace
Foundry, Dundee, in the County of Forfar, North Britain, Engineers, do hereby
declare the nature of this invention to be as follows, that is to say: -
Our said invention relates to mangling, calendering, or finishing machines of the
class designed for applying considerable pressare to the woven fabrics which are
submitted to the action of the rollers of the machines; and it comprises improved
arrangements for applying the pressure.
The bearings of the rollers of a machine of the kind to which the improvements
are applicable, are fitted to work in vertical guides in the housings, gables, or
main frames of the machine, and in carrying out the present invention the bearings
of the uppermost roller are acted upon by short rods, the rod of each bearing
being jointed between a pair of plates forming a lever one end of which is
centered on an upward extension of the housing at one side of the bearing. The
other end of each lever has jointed to it a rod extending vertically downwards
through a passage formed in the housing at the other side of the bearing. The
two rods jointed at their upper ends to the bearing levers, are at their lower ends
jointed to levers at or near the opposite ends of a horizontal rocking shaft, carried
in bearings fixed under the bases of the two housings; and on this rocking shaft a
lever or pair of levers fixed at the middle of its length or equidistantly on each
side of the middle is connected to the ram of an hydraulic cylinder by means of
which the pressure is applied. The pressure is communicated from the single
cylinder, through the rocking shaft and vertical rods to the bearing levers, and is
equally applied to the bearings at the opposite ends of the roller, a uniform
pressure on the fabric being thereby secured throughout the extent of the roller
in contact with the fabric.
The hydraulic cylinder may be conveniently placed horizontally in a box or
support fixed to the bases of the housings; or the cylinder may be placed vertically
or in any other suitable position. The rocking shaft may be solid or tubular; it
is by preference made of such material and dimensions as to possess some torsional
resiliency, in order that the pressure on the roller bearings may act with some
elasticity.

Improvements in Machines for Mangling, Calendering, or Finishing
Woven Fabrics.
We, WILLIAM ROBERTSON, and JAMES GUTHRIE ORCHAR, of Wallace
Foundry, Dundee, in the County of Forfar, North Britain, Engineers, 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, that is to say :-
Our said invention relates to mangling, calendering, or finishing machines of

page_text: the class designed for applying considerable pressure to the woven fabrics which
are submitted to the action of the rollers of the machines; and it comprises
improved arrangements for applying the pressure.
The bearings of the rollers of a machine of the kind to which the improvements
are applicable, are fitted to work in vertical guides in the housings, gables, or
main frames of the machine, and in carrying out the present invention the
bearings of the uppermost roller are acted upon by hydraulic apparatus through
short rods and intermediate parts hereinafter described.
And in order that our said invention and the manner of performing the same
may be properly understood we hereunto append two sheets of explanatory
drawings, to be hereinafter referred to, and showing a machine as made according
to the invention.
Figure, 1, on Sheet, 1, of the drawings is a front elevation, and Figure, 2, on
Sheet, 2, is a transverse vertical section.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
As shown in the drawings the bearings, A, of the uppermost roller, B, are acted
upon by short rods, C, the rod of each bearing being jointed between a pair of
plates forming a lever, D, one end of which is centered on an upward. extension, E,
of the housing, G, at one side of the bearing. The other end of each lever, D,
has jointed to it a rod, H, extending vertically downwards through a passage
formed in the housing, G, at the other side of the bearing, A. The two rods, H,
jointed at their upper ends to the bearing levers, D, are at their lower ends
jointed to levers, J, at or near the opposite ends of a horizontal rocking shaft, K,
carried in bearings, L, fixed under the bases of the two housings, G; and on this
rocking shaft, K, a pair of levers, M, fixed equidistantly on each side of the
middle is connected by rods, F, to the ram, N, of an hydraulic cylinder, P, by
means of which the pressure is applied. The pressure is communicated from the
single cylinder, P, through the rocking shaft, K, and vertical rods, H, to the
bearing levers, D, and is equally applied to the bearings, A, at the opposite ends
of the roller, B, a uniform pressure on the fabric being thereby secured throughout
the extent of the roller in contact with the fabric.
The hydraulic cylinder, P, is placed horizontally in a box or support, Q, fixed
to the bases of the housings, G. The cylinder, P, however may be placed
vertically or in any other suitable position. The rocking shaft, K, may be solid
or tubular; it is by preference made of such material and dimensions as to possess
some torsional resiliency, in order that the pressure on the roller bearings, A, may
act with some elasticity.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In a machine of the kind herein before described, applying pressure to the
bearings of the uppermost roller by means of rods actuated through levers and
other rods by a rocking shaft having on it levers connected by rods to the ram of
an hydraulic cylinder, substantially as and for the purposes herein before described
and as shown in the accompanying drawings.
