An Improved Wringing and Mangling Machine.
We, WILLIAM MCLEAN and JOHN MCLEAN, Engineers, both of 22, Grosvenor
Street, Belfast, do hereby declare the nature of this invention to bo as follows;-
―
This invention relates to wringing and mangling machines for pressing and
finishing textile fabrics of all kinds and it has for its object mainly to construct
a simple and eflicient machine which will minimize the risk of accident.
The main feature of the invention is that, although revolving rollers are
employed as in similar machines heretofore in use, the operator stands on the
opposite side of the machine to that on which the work is taken in by the
revolving rollers.
Two rollers are, by preference, used and the goods to be operated upon are
placed on the top of the upper roller and are carried forward and downward by
said roller, being guided in their descent by means of a curved guard or its
equivalent secured to the machine, and are fed in between the upper roller and
the lower roller and delivered out, at the front, on a board or table. The guard
forms in combination also a guide and feeder to the "take" of the rollers.
The guard is preferably adjustable and it is or may be also provided with
hinged and adjustable pressure levers or weights so as to allow for any irregularity
in the thickness of the goods.
The bottom roller is preferably made larger in diameter than the top roller and
the centre of the axles of the rollers are not in direct perpendicular line with cach
other but the axle of the top roller is placed in advance of the perpendicular line
of the centre of the bottom roller to an extent equal to the differences of the
diameter of the rollers. With this arrangement the front edge of the rollers is
in a direct perpendicular line whilst the bottom roller extends backwards from the
perpendicular line, beyond the top roller, to an extent equal to its extra diameter
and thereby performs a lifting action when rotating.
If desired the rollers may be made of equal, or of different diameters, and the
line of the axle centres be placed at any angle from the perpendicular to the
horizontal so as suit the requirements in the treatment of various classes of
goods.
For certain classes of goods we adopt a series of small rollers which take the
place and do the work of the guard aforesaid. But in any and all cases the
operator stands at the opposite side of the machine from that which the goods
are taken in between pressure rollers and places the goods on top of the pressure
rollers and not between them as heretofore.
The pressure applied to the top roller is derived from two large adjustable
spiral or helical springs which act direct on the two bearing bushes of the top roller,
said roller being supported by means of adjustable wedge bars or screws so as to
prevent the rollers coming in contact with each other, thus reducing friction and
strain when the rollers are not in actual work.

page_text: The frame of the machine is composed of two cast iron ends united by means
of a cast iron stay-trough.
The bolt fork handle is so arranged as to form a lock to the guard so that
it cannot be lifted until the belt is lifted on to the loose pulley; and the belt
cannot be brought back on to the fast pulley until the guard is shut down into t
its proper position.

An improved Wringing and Mangling Machine.
We, WILLIAM MOLEAN and JOHN MOLEAN, Engineers, both of 22, Grosvenor
Street, Belfast, 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:-
This invention relates to wringing and mangling machines for pressing and
finishing textile fabrics of all kinds and it has for its object mainly to construct
a simple and efficient machine which will minimise the risk of accident.
The main feature of the invention is that, although revolving rollers are
employed as in similar machines horetofore in use, the operator stands on the
opposite side of the machine to that on which the work is taken in by the
revolving rollers.
Two rollers are, by preference, used and the goods to be operated upon are
placed on the top of the upper roller and are carried forward and downward by
said roller, being guided in their descent by means of a curved guard or its
equivalent secured to the machine, and aro fed in between the upper roller and
the lower roller and delivered out, at the front, on a board or table. The guard
forms in combination also a guide and feeder to the take" of the rollers.
The guard is preferably adjustable and it is or may be also provided with
hinged and adjustable pressure levers or weights so as to allow for any irregularity
in the thickness of the goods.
The bottom roller is preferably made larger in diameter than the top roller and
the centre of the axles of the rollers are not in direct perpendicular line with each
other but the axle of the top roller is placed in advance of the perpendicular line
of the centre of the bottom roller to an extent equal to the differences of the
diameters of the rollers. With this arrangement the front edge of the rollers is
in a direct perpendicular line whilst the bottom roller extends backwards from the
perpendicular line beyond the top roller, to an extent equal to its extra diameter
and thereby performs a lifting action when rotating.
If desired the rollers may be made of equal, or of different diameters and the
line of the axle centres be placed at any angle from the perpendicular to the
horizontul so as to suit the requirements in the treatment of various classes of
goods.
For certain classes of goods we adopt a series of small rollers which take the
place and do the work of the guard aforesaid. But in any and all cases the 4
operator stands at the opposite side of the machine from that which the goods
are taken in between the pressure rollers and places the goods on top of the pressure
rollers and not between them as heretofore.
The pressure applied to the top rollor is derived from two large adjustable

page_text: spiral or helical springs which act direct on the bearing bushes of the top roller,
said roller being supported by means of adjustable wedge bars or screws so as to
prevent the rollers coming in contact with each other, thus reducing friction and
strain when the rollers are not in actual work.
The frame of the machine is composed of two cast iron ends united by means
of a cast iron stay-trough.
The belt fork handle may be so arranged as to form a lock to the guard so that
it cannot be lifted until the belt is lifted on to the loose pulley; and the belt
cannot be brought back on to the fast pulley until the guard is shut down into
its proper position.
And in order that our said invention may be properly understood, we have
hereunto appended an explanatory sheet of drawings, whereon,
.
Fig. 1 is a side view and Fig. 2 a plan of the wringing and mangling machine
Fig. 3 is a vortical section to an enlarged scale of the same.
Fig. 4 is a perspective view.
Fig. 5 is a detail view.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.

The machine consists of two cast iron side frames or ends a, a, which are joined
together by means of a cast iron stay-trough b which latter is made with lugs b
through which the bolts c are passed. d, e, are the two rollers the top one of
which may, as shown, be smaller than the other and whose axle may be in advance
of a perpendicular line drawn through the centre of the bottom roller
extent equal to the differences of the diameters of the rollers.
The bearing bushes f, g, of the rollers work in the guides of
the frame. Pressure is applied to the top roller by means of spiral pressure
springs,, which bear directly upon the bushes of the top roller at their lower
ends and against bridges i, j, at their upper ends. Long screw bolts pass
through these bridges and are secured at their upper ands by means of nuts m
and at their lower ends by means of nuts n. By screwing up or slackening the
nuts the tension of the springs can be adjusted. To prevent the top roller
coming in contact with the lower one its bearing bushes are supported on wedge
These wedge bars can be adjusted vertically in the slots p of the
frame. The curved guard 7 is hinged at g', q', to a cross bar r which is supported
at each end in the lugs s of the casings for the springs.

is the delivery table, the usual driving gear and to the belt.
The main feature of this invention is the fact that as already explained the
operator stands on the opposite side of the machine to that in which the work
is taken in by the revolving rollers. He places the goods upon the top of the
upper roller and between it and the guard, as shown at A, the goods being
carried forward and downward by the upper roller and then passing between
the rollers to the delivery table or board. The guard 9, as shown at Fig. 3,
forms a guide and feeder to the " take" of the rollers.
The curved guard is preferably provided with one or more adjustable pressure
lovers and weights y.
As hereinbefore stated instead of having a sheet metal guard 7 a number of
rollera or equivalent may be used.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to bo performed, we declare that what
we consider novel and desire to claim is:-
1. A wringing and mangling machine having a guard or its equivalent so
arranged that the operator can stand and feed the material to the rollers at the
opposite side of the machine to that at which tho work is taken in between the
rollers substantially as set forth.
2. The construction or arrangement and combination of parts of the wringing

the drawings annexed.
