Improvements in Machinery for Pressing and Finishing Woven and
Felted Fabrics.
I, THOMAS CORSTANTINE FAWCETT, of Whitehouse Engineering Works, Hunslet
Road, Leeds, in the County of York, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to a prior application for patent made by me on the
16th of February A.D. 1888, No 2339, which invention consisted in the employ-
ment of toggle jointed levers for lifting one pressing plate against another, and my
improvements consist,
Firstly, in arranging the toggle jointed levers which are placed in front of each
other, so that the knees or joints of the levers advance towards each other and also
recede from each other, whereby the strain upon the several parts is distributed and
equalized.
Secondly, my invention relates to means to be employed for drawing the pressed
fabric from between the pressing plates by one or more pairs of reciprocating jaws,
preferably arranged for the upper jaw to be the one which opens and closes. These
jaws are capable of sliding backwards and forwards upon stationary horizontal rods,
the movement of the jaws being effected by means of rods and levers actuated by
The upper
cams or other means from any convenient rotary part of the machine.
nipping jaw is made to open and close at the proper time for the purpose of seizing
hold of the fabric and releasing its hold, by a pair of small toggle jointed levers.
Underneath the reciprocating nipping jaws is an endless apron upon which the newly
pressed length of fabric rests.
Thirdly, my invention relates to means to be employed for measuring the fabric
which passes between the pressing plates, and this I propose to do by means of the
reciprocating jaws which draw a given length of fabric from between the pressing
plates at each forward movement, such jaws actuating any convenient arrangement
of ratchets and pawls and wheels, which in their turn indicate upon a dial plate the
length of fabric operated upon or about to be operated upon. Instead of employing
the reciprocatory jaws for measuring the fabric, such fabric may pass around a roller
of a given diameter, the rotary motion of which roller operates other wheels so as to
indicate upon a dial the length of fabric.
Fourthly, my invention relates to means to be employed to "cuttle" the said
fabric after it has been pressed, but my said improvements in cuttling only apply
when more than one piece of fabric is being pressed at the same time.
In carrying out this part of my invention, if three pieces of fabric are being
pressed, rollers are arranged to divide the three fabrics, carried by a suitable frame-
work, such rollers all being geared by wheels, consequently when one or more lengths
of fabric have been drawn by the jaws from between the pressing plates, rotary
motion is given to the first cuttling roller, and through the intervention of gear
wheels to the remainder.
To
Lastly. My invention relates to the feeding end of the machine, at which in practice
I find that the fabric enters the machine on the twist or in an uneven manner.
prevent this I employ a number of bars placed at an angle, the fabric passing
between the said bars, which is thereby straightened out and prevented from
twisting, by which means the said fabric enters the machine in an open or
distended state.

Improvements in Machinery for Pressing and Finishing Woven and
Felted Fabrics.
I, THOMAS CONSTANTINE FAWCETT, of Whitehouse Engineering Works, Hunslet
Road, Leens, in the County of York, Engineer, 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 has referenco to a prior application for Patent made by me on
the 16th of February A.D. 1888 No 2389, which invention consisted in the employ-
ment of toggle jointed levers for lifting one pressing plate against another, and my
present improvements consists,
Firstly, in arranging the toggle jointed levers which are placed in front of each
other, so that the knees or joints of the levers advance towards each other and also
recede from each other, whereby the strain upon the several parts is distributed and
equalized.
In order that my invention may be better understood, I will now make reference
to the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is front
elevation of my improved cloth pressing machine and Fig. 2 is end view of the
delivery end of the machine. A and B are the pressing plates between which the
facric Ċ passes for the purpose of being pressed, which operation is performed inter-
mittently. The lower pressing plate B is caused to rise and fall for the purpose of
pressing the cloth, by means of toggle-jointed levers D and E actuated by crank F
and connecting rods G, but instead of the joints of the toggle jointed levers D and E
moving in the same direction at the same time, I arrange the joints as shown in
Fig. 1 where the said knees recede from each other and advance towards each other,
whereby the pressure and strain upon the said levers is equalized.
Secondly, my invention relates to means to be employed for drawing the pressed
fabric from between the pressing plates by one or more pairs of reciprocating jaws,
preferably arranged for the upper jaw to be the one which opens and closes.
These
jaws are capable of sliding backwards and forwards upon horizontal stationary
rods, the movement of the jaws being effected by means of rods and levers actuated
by caus or other means from any convenient, rotary part of the machine.
upper nipping jaw is made to open and close at the proper time for the purpose of
seizing hold of the fabric and releasing its hold, by a pair of small toggle-jointed
levers. Underneath the reciprocating nipping jaws is an endless apron upon which
the newly pressed length of fabric rests.
The
This part of my invention is shown in Fig. 1, where H represents a stationary
rod projecting from the upper pressing plate A, a corresponding rod being on the
opposite side of the machine. Upon the rod H is a boss or tube I capable of sliding
backwards and forwards on the said rod. A transverse bar J is employed, carried
by the boss 1, but its connection there with is not shown, for the sake of clearness,
but the said transverse bar and boss move backward and forward together horizontally
by means of the connecting rods K and I actuated by another connecting rod M
connected to the face of the wheel N so that as the said wheel revolves the said
boss and transverse bar are made to reciprocate. For the purpose of seizing hold
of the cloth every time a length has been pressed between the plates, another
transverse bar or jaw O is employed, caused to open and close upon the cloth,
and upon the bar J by means of the small toggle-jointed levers P which are closed
by the levers K and I just when they commence to slide the hoss 1 upon the bar H,
but the said jaws open and release their hold of the cloth when they comunence to
return upon the bar H, by which means, at every forward movement, the jaws
close, seizing hold of the cloth and drawing out from between the pressing plates the
length which has been pressed, at the same time drawing between the plates a
length of cloth unpressed, so that when the pressing plates close again, another length
of cloth is operated upon, and this goes on intermittently so long as the machine is

page_text: at work. Q represents an endless travelling apron for the purpse of receiving the
newly pressed length of cloth as it leaves the pressing plates, such apron being made
to travel with the cloth every time the nipping jaws advance, as the cloth and the
upper portion of the endless apron lie between the nipping jaws, and are gripped
thereby and made to travel along with the cloth.
Thirdly, my invention relates to the feeding end of the machine, at which in
practice I find that the fabric enters the machine on the twist or in an uneven manner.
To prevent this I employ a number of bars placed at an angle, the fabric passing
between the said bars, which is thereby straightened out and prevented from twisting,
by which means the said fabric enters the machine in an open or distended state.
This part of my invention is shewn more plainly in Fig. 2, where R represents
three transverse bars or rollers placed at an angle attached to vertical side pieces S.
Through and between these diagonal transverse bars the fabric is made to travel as
shewn in Fig. 1, which bars prevent the open travelling fabric getting twisted or
out of parallel with the plates, consequently the fabric enters the machine in a straight
and open condition.
Having now particularly described the nature of my said invention, and in
what manner the same is to be performed, I declare that what I claim is :-
Firstly. In cloth pressing machines, the arrangement of toggle jointed levers inade
to advance towards each other and recede from each other as described and shewn
in Fig. 1.
Secondly. In cloth pressing machines, the employment of reciprocating nipping
jaws J and O made to open and close by toggle jointed levers as described and shewn
in Fig. 1.
Thirdly. In cloth pressing machines, the arrangement of diagonal bars or rollers R
placed at the feeding end of the machine, for the purpose of opening out and
straightening the travelling fabric as herein described and illustrated.
