I, THOMAS CONSTANTINE FAWOETT, of Whitehouse Engineering Works, Hunslet,
Leeds, in the County of York, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
My invention consists in a new arrangement and combination of parts to be
employed for pressing and finishing woven and felted fabrics.
In carrrying out iny invention I employ any suitable form of foundation plate,
through which pass vertically long rods or bolts, to the upper ends of which is
attached a strong metal plate, partially hollow for the reception of steam or other
heating media, and on the top of this hollow plate or steam chest are a number of
strong spiral or other form of springs employed as hereinafter explained. Under-
neath the hollow plate above mentioned is another hollow plate, which is also supplied
with steam or other heating media; the faces of the said plates being opposed to each
other for the purpose of pressing the fabric placed between them. The lower hollow
heated plate is connected to three or other suitable number of toggle jointed levers,
the whole of which sets of levers are connected to one horizontal link, such link
by means of a lever arm being connected to a crank so that on the motion of the said
crank the toggle jointed levers are actuated in such a manner as to cause the lower
steam plate to be raised, in doing which the fabric resting between the two plates is
pressed, and by making the connecting rod or the length of the crank arm sufficiently
long to throw the joints of the toggle jointed levers past a vertical line, the bottom
pressing plate gives to the fabric a double squeeze for one revolution of the crank
haft, and in order to maintain the pressure of the plates upon the cloth, the bottom
pressing plate is lifted sufficiently to cause the upper pressing plate to rise some little
distance against the action of the strong spiral springs at the top thereof previously
mentioned, so that when the bottom pressing plate begins to descend the action of
he strong springs will be sufficient to force the upper pressing plate down into contact
with the bottom pressing plate, consequently instead of the pressure being relieved from

page_text: between the two plates immediately upon the bottom pressing plate commencing to
descend, the spiral springs by forcing the upper plate down lengthens or increases the
duration of the pressure upon the cloth; therefore for one revolution of the crank shaft
I obtain considerable "dwell"
or pressure upon the cloth.
This machine works intermittently and the cloth under operation is caused to travel 5
the length of the plate each moment the plates are separated by the action of the
toggle jointed levers, the intermittent motion of the cloth being imparted by any well-
known mechanical appliances for giving intermittent motion to the roller, over which
the cloth passes, or by means of an oscillatory. lever arm, the length of stroke being
equal to the length of the pressing plates so that each time the pressure of the plates 1
is removed the oscillatory lever is timed to operate and draw the newly pressed cloth
from between the pressing plates at the same time introducing a fresh length to be
operated upon, and this goes on so long as the machine is in operation.

A New or Improved Machine for Pressing and Finishing Woven
and Felted Fabrics.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works, Hunslet,
Leeds, in the County of York, Engineer, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention consists in a new arrangement and construction of apparatus to be
employed in pressing and finishing woven and felted fabrics.
In carrying out my invention I employ any suitable form of foundation plate,
through which pass vertically long rods or bolts, near the upper end of which rods are
placed two strong metal plates, the upper one resting upon collars on the said rods,
whilst the lower plate is supported by and connected to toggle jointed levers, operated
by crank and connecting rod, by which the lower plate is made to move slightly up
and down. The fabric to be pressed is placed between two plates, both of which may
be hollow for the reception of steam or other heating media. On the upper end of the
long vertical bolts or rods are strong spiral springs employed to force the upper plate
against the lower one, and also for the purpose of yielding when the bottom pressing
plate is at its highest point. A crank and rod for operating a pawl and ratchet
wheel is also employed for the purpose of removing from the pressing plates a given
length of cloth, and also for introducing another length of cloth to be pressed.
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying sheets
of Drawings, wherein Fig. 1 is side elevation of a machine for pressing fabrics, con-
structed and arranged according to my invention. Fig. 2 is plan view thereof, and
Fig. 3 is end view partly in section. A représents the foundation plate of the machine,
B the upper pressing plate, and C the lower pressing plate. The two pressing plates
are guided and kept in position by means of six rods or bolts D passing vertically
through the foundation plate A and through both pressing plates, as the drawing
illustrates, whilst on the upper end of each bolt is a strong spiral spring E, which are
adjusted by nuts F. The upper pressing plate B rests upon collars a formed on the
long bolts D, as shown in Fig. 3, whilst the lower pressing plate C is connected to and
caused to be raised and lowered by toggle jointed levers & connected together by side
links H, one end of which is attached by pin b to connecting rods I carried by
crank J, operated by strong gearing K and L, which receive their rotary motion from the
main driving shaft M also carrying driving pulleys N. The connecting rods I, or the
crank J, are of such a length as to throw the toggle jointed levers beyond a vertical
line so that as the crank revolves the lower pressing plate is lifted up against the
upper pressing plate, pressing the fabric lying between the two plates, but in conse-
quence of the toggle jointed levers going past or beyond a vertical line, the bottom
pressing plate will give the fabric a squeeze both when the connecting rods I advance
and on their return motion, consequently the fabric receives a double squeeze for one
revolution of the crank shaft; and in order to maintain the pressure of the plates

page_text: upon the fabric, (even when the connecting rods I are receding) the toggles are
arranged to lift the bottom pressing plate sufficiently high to cause the upper pressing
plate to rise some little distance off the collars a against the downward action of the
strong spiral springs E, so that when the bottom pressing plate begins to descend by
the receding action of the connecting rods I, the action of the strong spiral springs E,
so that when the bottom pressing plate begins to descend by the receding action of
the connecting rods I, the action of the strong springs will be sufficient to cause
the upper pressing plate to follow the lower one, so as to maintain the pressure
or nip between the two plates, consequently, instead of the pressure between the two
plates being relieved immediately upon the bottom pressing plate commencing to
descend, the spiral spring, by forcing the upper plate down, lengthens or increases the
duration of the pressure on the fabric, therefore, for one revolution of the crank shaft
I obtain not only two squeezes, but a considerable "dwell" or pressure upon the
fabric.
Instead of the toggle jointed levers G being connected by a rod H and causing
both levers G to bend their knees both backward and forward together, the rod H
may be removed, and the toggle jointed levers G may be caused to bend towards and
from each other.
The pressing of the fabric in this machine is intermittent, and the fabric under
operation is made to travel the length of the pressing plate, each moment the
plates are separated by the action of the toggle jointed levers and crank. The
intermittent notion of the cloth, which is indicated by letter c, is imparted by means
of a crank placed on the end of the crank shaft J. The crank & carries a pin e
working in the slotted end of the rod f, which rod is also connected to the lever g
capable of oscillating upon fulcrum . On the lower end of this lever is a pawl
or catch taking into the teeth of the wheel h gearing into a pinion on the end of
the drawing-on roller P.
Therefore when the crank d revolves, and occupies the position indicated in the
Drawings, the rod f will have been pushed forward in the direction of the arrow m
to its furthest point outwards, but as the pressing operation is now going on, it is
necessary for the wheels and to remain stationary, to allow which the pin e will be
temporarily sliding in the slotted end of the rod f, but the crank d is so timed that
as soon as the pressing plates are open, the pin e will have travelled to the end
of the slot in rod f, and will commence to pull the rod in the opposite direction
to the arrow m. At the same time the pawl, which is in gear with the teeth of
wheel, will bring the wheel forward a given distance, imparting rotary motion to
the pinion, causing the drawing-on roller P to pull so much fabric from under
the plates as has been pressed, at the same time introducing between the plates the
same length of unpressed fabric to be operated upon in like manner, and this goes on
automatically so long as the machine is in operation, consequently the machine requires
very little attention.

In order to improve the finish given to the fabric, I insert "
the metal plate and the fabric, but the use of "press paper " forms no part of my
invention.
Instead of all the springs E being actuated by independent nuts F, they may
be adjusted by worms and wheels operated from one hand wheel, as will be
understood by mechanicians.
Steam or other heating media is admitted to the bottom pressing plate by means of
pipe n as shewn in Fig. 3.
Having now particularly described and ascertained the nature of my said inven-

other forms of toggle jointed levers than those herein shewn may be used, therefore
what I claim is :-
