Improvements in Mangling, Calendering, or Finishing Machines.
We, WILLIAM BRUCE MAIR, and JOSEPH LINDSAY, of Blackness 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 has for its object to improve the construction of mangling,
calendering or finishing machines, and to improve, simplify, and expedite the
operations of such machines.
Our invention consists according to one modification in employing two upper
rollers in combination with one lower roller, the latter being pressed upwards by
two hydraulic cylinders acting one on each end or by a single hydraulic cylinder
acting through levers or by weighted levers. The cloth to be operated on is wound
on a roller or beam which when in action is situated in the grip of the three rollers,
and is at each revolution, acted on considerably more than in ordinary machines,
whilst fewer reversals of the motion are required.
The constructive details of the machine are susceptible of considerable variation;
but the following particulars of an example may be given. The gables, housings,
or end frames of the machine are massive castings connected by girders, andiare
made with bearings for the three rollers, the bearing block for the bottom roller,
being fitted to slide vertically in guides, so as to be moved by the hydraulic
cylinders or cylinder and to allow of the cloth beam being entered into and removed
out of position. The cloth beams are carried by a pair of rings as in some existing
machines, the rings being constructed to hold three beams, namely one in action,
one being filled at one side, and one being emptied at the other side. A roller
held by levers is, preferably, arranged to lie on the top of the beam being filled,
to ensure tightness and evenness.
The bolts by which the bearing covers of the upper rollers are secured have their
inner ends screwed into steel nut blocks inserted in sockets formed for them in the
gables, one nut block in each housing receiving the two inner bolts of the upper
bearings, and two nut blocks which receive the other bolts of the upper bearings,
also receiving the upper ends of vertical bolts which secure the hydraulic cylinder
to the bottom of the gable. This arrangement of bolts and nut blocks by taking
up the strains to a large extent will correspondingly relieve the gables.
Instead of the two rollers being uppermost they may be below or to one side of
the third roller.
We by preference make the machine self-contained and so as to receive power
from a single driving belt or pair of belts, the gearing for giving the different
movements required in the machine being arranged in immediate connection, here-
with. The two upper rollers are driven by means of a pinion gearing with spur
wheels on their shafts; and the bottom roller may also be similarly driven .if
thought desirable.
Any of the rollers may be arranged to be heated internally by means of steam or
gas or heated air.
Dated this Twenty-sixth day of December 1895.

We, WILLIAM BRUCE MAIR, and JOSEPH LINDSAY, of Blackness 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 has for its object to improve the construction of mangling,
calendering, or finishing machines, and' to improve, simplify, and expedite the
operations of such machines.
Our invention comprises generally an improved construction and arrangement of
the parts of a mangling, calendering, or finishing machine, but it chiefly consists in
employing, for the mangling or like operation, two rollers in combination with
another roller, the latter being pressed towards the former, either by two hydraulic
cylinders acting one on each end, or by a single hydraulic cylinder acting through
'levers, or by weighted levers. The cloth to be operated on is wound on a roller
or beam which when in action is situated in the grip of the three rollers, and is
at each revolution acted on considerably more than in ordinary machines, whilst
fewer reversals of the motion are required.
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 by way of example, a machine as made
with our improvements.
Figures, 1, and 2, of the drawings are respectively a side and an end elevation of
the machine.
In these drawings the same reference letters and numerals are used to mark the
'same or like parts wherever they are repeated.
The constructive details of the machine are susceptible of considerable variation.
In the machine shown, by way of example, in the drawings, however, the gables,
housings, or end frames, A, are massive castings connected by girders, B, and are
made with bearings, C, for the three rollers, D, D, and F. The blocks, E, holding
'the bearings, C, for the bottom roller, F, are fitted to slide vertically in guides, G,
'formed in the gables, A, so as to he moved by the hydraulic cylinders, H, and to
allow of the cloth beam being entered into and removed out of position.
cloth beams, J, are carried by a pair of rings, K, as in some existing machines, the
rings being constructed to hold three beams, namely one in action, one being
filled at one side, and one being emptied at the other side. A roller, L, held
by levers, not shown, is preferably arranged to lie on the top of the beam, J, being
filled to ensure tightness and evenness.
The
The bolts by which the bearing covers, N, of the upper rollers, D, are secured
'have their inner ends screwed into steel nut blocks, P, and Q, inserted in sockets
formed for them in the gables, A. One nut block, P, in each housing receives the
two inner bolts, R, of the upper bearings, C, while two nut blocks, Q, receive the
other bolts, S, of the upper bearings, and also the upper ends of vertical holts, T,
which secure the hydraulic cylinder, H, to the bottom of the gable. This arrange-
ment of bolts, R, S, T, and nut blocks, P, and Q, by taking up the strains to a large
extent will correspondingly relieve the gables, A.
Instead of the two rollers, D, being uppermost they may be below or to one side
of the third roller.
We, by preference, make the machine self-contained and so as to receive power
from a single driving belt or pair of belts, the gearing for giving the different
movements required in the machine being arranged in iminediate connection there-
with.

page_text: The two upper rollers, D, are driven by means of a pinion, U, gearing with
spur wheels, V, on their shafts, V 1, the pinion, U, being on a shaft, V 2,
carried in bearings, V 3, on the gable tops and having on it a spur wheel, V 4,
gearing with a pinion, V 5, on a first-motion shaft, V 6. When it is desired to
also drive the bottom roller, F, directly, a spur wheel, W, on its shaft, W 1, is
driven by a spur wheel W 2, on a shaft, W 3, carried in bearings, W 4, on the
gable ends, and gearing with one of the spur wheels, V.
Any of the rollers, D, and E, may be arranged to be heated internally by means
of steam or gas or heated air.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. The construction, arrangement, and combination of parts constituting the
improved mangling, calendering, or finishing machine substantially as herein before
described.
2. In a mangling, calendering, or finishing machine, combining three rollers
suitably driven by gearing, and arranged so that one can be pressed towards the
other two by hydraulic machinery substantially as and for the purposes hereinbefore
described.
3. The arrangement of the bolts (R, S, T) and nut blocks (P, Q) substantially
as and for the purposes hereinbefore described.
