PROVISIONAL SPECIFICATION.
Improvements in Cloth-pressing Machines.
I, ERNST GESSNER of Aue in the Kingdom of Saxony, Machine Builder, do
hereby declare the nature of this invention to be as follows:-
In
These improvements relate to cloth-pressing machines, such as those for which
Letters Patent were granted to me dated December 27th 1877, No. 4913.
the machines described in the Specification of the aforesaid Patent, the cloth is
pressed between a revolving cylinder and two presser-boxes or plates mounted
upon pairs of upwardly-extending pivoted arms oppositely arranged at the two
sides of the cylinder and connected by a spring provided with screw-threads and
nuts upon its outer ends for the purpose of moving the presser plates to or from
the cylinder to exert or relax the pressure. Some of the modifications described
in the said Patent comprise a combination of three presser-plates arranged around
one cylinder. The operation of the presser-plates by means of screws is difficult
and slow, and my present invention has for its object to provide means whereby
to enable the presser plates to be moved to or from the cylinder almost instan-
taneously by a single movement of a hand lever or by a winch-handle.
In the accompanying drawings, forming part of this Specification,
Figures 1 to 10 are elevations of pressing machines with two presser-plates
mounted in pairs of upwardly-extending pivoted arms oppositely arranged at the
two sides of the cylinder.
Figures 11 to 15 shew elevations of pressing machines having three presser-
plates arranged around the cylinder, two of the said presser-plates being mounted
upon pivoted arms.
In all these various arrangements, the mechanism for moving the presser-plates
to and from the cylinder is such that it acts in the manner of a toggle-joint.
In all the figures, except Figures 8 and 11, the presser-plates are shewn in position
for pressing.
In Figure 1, B and B are the two presser-plates arranged at opposite sides of
the cylinder A, each being provided with journals mounted in pairs of arms C
and pivoted at their lower ends. The mechanism for moving the presser-
plates B B to or from the cylinder, which is described with reference to one end
only of the machine, consists of a connecting-rod F pivoted to the upper end of
arm C coupled by a link E to a hand lever G pivoted to the other arm C, the
connecting-rod F being provided with a stud and friction roller f working in a
curved slot S in the arm C, so that on raising or lowering the hand lever the roller
is forced along in the slot which acts as an inclined plane whereby the arms C C¹
are caused to be drawn apart or forced towards the cylinder the outward motion of
the arms being limited by chains k k connected to them and to the frame N. The
connecting rod F is provided with a right and left screw-coupling whereby to
adjust the length of the connecting-rod as required and it may be formed with a
loop, as shewn in dotted lines, so as to act as a spring for applying a yielding
pressure. The arm C is pivoted to the end frame N whilst the arm is pivoted
to the upwardly-projecting short arm of a weighted elbow-lever J fulcrumed in the
foot of the frame and acting so as to apply a yielding pressure and allow the
presser-plates to yield somewhat when the thickness of the cloth increases or in
the event of any obstruction entering between the cylinder and the presser-plates.
M is a screw-stop, for the lever J to rest upon.

page_text: In Figure 2 the movement of the presser plates is effected by means of an
eccentric E and hand lever G secured to shaft H mounted in the upper end of the
arm C and passing freely through a longitudinal slot in the connecting-rod F, the
eccentric working between and against two rollers D D' attached to the connecting
rod F, so that by turning the eccentric to right or left the arms C C' are moved
to or from the cylinder. The connecting rod F is made in two parts connected by
jam-nuts to vary its length at will, and is jointed to the upper end of arm C¹ which
is pivoted on a weighted elbow-lever J to allow a yielding pressure, as in Figure 1,
bolts K K limiting the outward movement of the arms instead of chains.
In Figure 3 the arms C and C¹ are connected by the rod F one end of which
forms the strap of an eccentric E fixed to the shaft H mounted in the arm C and
provided with a hand lever G, the other end of the connecting rod F passing
through a socket f1 pivoted to the arm C' so as to accommodate itself to the angular
movement of the rod F. The end of the rod F is screw-threaded and provided
with a nut m at the inner side of the socket /¹ and with a hand-wheel R at the
outer end, a spiral spring D being interposed between the hand-wheel and the
socket and compressed more or less by the hand wheel to permit of a more or less
yielding pressure. A second rod F' pivoted to the eccentric connects the latter
with an arm or stay on the end frame N, thus giving a positive point of resistance
whereby to ensure the simultaneous and equal motion of the presser plates.
In Figure 4 the ends of the connecting rod F are reversely screw-threaded and
work in nuts ff pivoted to the upper ends of the two arms C C₁ so as to
accommodate themselves to the angular motions of the arms.
By means of bevel
wheels W, shaft H, and winch handle R, the rod F can be rotated in either
direction, to move the presser plates to or from the cylinder. The arm C¹ is
pivoted to a weighted elbow-lever J whereby a yielding pressure of the presser-
plates is obtained and in order to actuate the presser-plates for the purpose of
releasing the pressure instantaneously a treadle lever G is employed to lift the
weighted lever J. B2 is a third presser-plate located below the cylinder and
pressed against the same independently of the other two, by means of a supporting-
screw, a spring D being interposed to admit of a yielding pressure.
In Figure 5 the connecting-rod F is pivoted to the arm C¹ and to the short
arm E of an elbow-lever E G fulcrumed on the arm C' and held in position for
applying pressure by a rod F' connected with a weighted lever J, the said rod F¹
being adjustable as to its length by means of a right and left screw coupling and
connected to the hand lever G by a hook so as to admit of being unhooked to
release the presser-plates. A treadle lever G¹ serves for lifting the weighted
lever J to relieve the pressure and facilitate releasing the lever G.
In Figure 6 the connecting rod F is jointed to the bend of the elbow-lever E G
which is pivoted by its short arm E to the arm C a second rod 9 being pivoted to
an arm on the boss of the lever arm E and to the frame N to ensure uniformity of
movement of the two arms C C', the arms C₁ being pivoted to the weighted lever J,
as before, for the purpose of giving a yielding quality to the pressure.
presser plate B³ may be arranged below the cylinder, as shewn in dotted lines,
and be pressed against the cylinder independently of the other two, by means of a
weighted lever J₁ K.
A third
In Figure 7 the upper ends of the two arms C C¹ are connected by a rod F
made in two parts coupled by right and left screw threads and a nut for adjusting
its length, a worm wheel r¹ in one with the nut being in gear with a worm ŕ turned
by a hand wheel. The stud c at the lower end of the arm C is supported in a slot
in the foot of the frame N and is connected by a toggle-joint E E with the hand
lever G fast upon shaft H by turning which the toggle may be straightened and
brought into position to exert pressure. The shaft H extends from end to end of
the machine and is journaled in the short arm of the weighted elbow-lever J
whereby a yielding pressure is obtained.
In Figure 8 the connecting rod F is jointed at one end to an elbow E formed
with a toothed segment with which gears a pinion upon the shaft H which is
"

page_text: turned by a hand wheel G for moving the arms ('C' to or from the cylinder. The
connecting rod F is jointed at its other end to an elbow lever g pivoted to the
arm C¹ and connected with the weighted lever J through a rod F¹ whereby a
yielding pressure is obtained. Two set-screws kk' mounted in bracket arms M M¹
on the end frame N limit the outward motion of the arms C C¹.
In Figure 9 the connecting rod F is jointed at one end to arms C' and at the
other to the hand lever G having an elbow E connected with the arm C through
the interposition of a weighted elbow lever T fast upon the shaft H mounted in
arm C for the purpose of giving a yielding quality to the pressure.
Instead of mounting both presser-plates in pivoted arms one of them B may
slide in a guide way P, as in Figure 10, while the other B₁ is arranged in the
usual manner in the lever arm C₁ the two being connected by a rod F and arm E
which is fast upon the shaft H. The rod F is arranged in the middle of the
machine below the cylinder and is curved so as to act as a spring and give
a yielding pressure.
In Figure 11 a pressing machine is shewn with three presser plates, two B B₁
being arranged on opposite sides of the cylinder A mounted in pivoted arms and
adjusted in the manner shewn in Figure 6. The third presser plate B2 is placed
below the cylinder and its journal slides in guide-ways P and being formed with a
projection f against which a toggle-joint E¹ E' acts so as to cause the presser-
plate to move up or down within the guide-way. F¹ is a rod connecting the
middle joint of the toggle with the lower extremity of the arm C so that any
motion of the said arm will be communicated to the third presser plate whereby all
three presser plates will be moved simultaneously to or from the cylinder. In
order to obtain a yielding pressure the arm C is pivoted to a weighted lever .1
fulcrumed in the frame N, a second weighted lever J' being connected with the
toggle-joint E' E. In case it should be required to operate the lower presser-
plate independently of the other two, the connecting rod F' may be attached to a
hand lever G¹, as shewn in dotted lines.
Figure 12 ehews three presser plates, the two opposite ones B B' being journaled
in the arms C C' and the third mounted in an arm C2 pivoted to the frame N
and placed below the cylinder. The arms C C¹ are connected by rods F FI
and elbow-lever E G, an O-shaped loop or hanger E¹ being connected to the
middle joint of the rods F F and to the journal of the presser plate B' whereby the
latter is suspended and brought into connection with the other two. By raising
the hand-lever G the presser plate B' is free to descend by its own weight until it
rests on the stop M whereupon the vertical arms are drawn back from the cylinder,
so that all three presser-plates are actuated by one movement of the hand lever.
In Figures 13, 14, and 15, the third presser plate B2 is stationary while the
cylinder A is pressed upon it, being journaled in bearings S sliding in guides P of
the end frame N.
In Figure 13 a toggle joint E El is connected to the bearing of the cylinder and
to the middle joint of the rods F F which are pivoted to the arms C C and
formed each with a loop for allowing of a yielding pressure. The lower link E' of
the toggle-joint has a hand lever G for operating it. By straightening the toggle-
joint the cylinder is forced down on to the lower presser plate B2 and the arms C C'
are drawn towards the cylinder. By the reverse movement the arms C C are
drawn back from the cylinder until they bear against the screw-stop k in bracket
arms M M' whereupon further flexure of the toggle causes the cylinder to be
raised from the lower presser-plate.

united by a right and left screw-coupling is pivoted at the
bearing of the cylinder A and at the upper end to the middle joint of the
rods FF connecting the arms C C' and formed with loops to afford a yielding
pressure, the rod F terminating in a strap embracing an eccentric E fast upon the

page_text: shaft H. When the eccentric is turned in one direction by the movement of the
hand-lever G fast on shaft H the arm C is drawn back first until it bears on
the stop K, then the other arm C' is moved away from the cylinder until it bears
against the stop K¹, and lastly the cylinder is raised from the third presser-
plate B. Conversely when pressure is to be exerted the cylinder goes down first
owing to its weight and the arms CC then move inwards to press their plates
against the cylinder.
Figure 15 shews a double-armed lever E' E2 fast upon the shaft H to the
opposite ends of which the arms C C¹ are connected by the yielding rods F F¹ the
connections being between the swinging arms C C and the lever arms E E¹
respectively as shewn. The shaft H is mounted in the frame N and is operated
by a hand lever G, and carries an eccentric E which is connected with the
bearing of the cylinder A through the rod F2 so that by turning the hand-lever G
the presser-plates B B' are drawn back from the cylinder and the cylinder is
raised by means of the eccentric. The presser plates B B' are arranged somewhat
above the level of the axis of the cylinder so as to be pressed obliquely downwards
against the cylinder whereby to increase the pressure of the cylinder against the
lower plate.
For the purpose of giving a yielding quality to the pressure, each arm C and C₁
may be connected with a weighted lever J as before described. In these pressing
machines a sheet metal jacket to be applied between the presser-plates, and the
cylinder, and it is to be understood that all the presser-plates of a machine may be
connected by one jacket only, or each may have a separate jacket, or the sheet-
metal jacket may be omitted entirely.

two sides of the cylinder.
Figures 11 to 15 shew elevations of pressing machines having three presser-plates

In Figure 1, B and B are the two presser-plates arranged at opposite sides of
the cylinder A, each being provided with journals mounted in pairs of arms C
and C pivoted at their lower ends. The mechanism for moving the presser-
plates B B' to or from the cylinder, (which mechanism is described with reference
to one end only of the machine), consists of a connecting-rod F pivoted to the upper
end of arm C coupled by a link E to a hand lever G pivoted to the other arm C,.
the connecting-rod F being provided with a stud and friction roller f working in a

the arms
In Figure 2 the movement of the presser plates is effected by means of an
eccentric E and hand lever G secured to shaft H mounted in the upper end of the
arm C and passing freely through a longitudinal slot in the connecting-rod F, the
eccentric working between and against two rollers D D' attached to the connecting
rod F, so that by turning the eccentric to right or left the arms C C¹ are moved to
or from the cylinder. The connecting rod F is made in two parts the one screw-
threaded and connected to the other by jam-nuts whereby to vary its length at will,
and is jointed to the upper end of arm C' which is pivoted on a weighted elbow-
lever to allow a yielding pressure, as in Figure 1, stops K K' limiting the
outward movement of the arms instead of chains.
In Figure 3 the arms C and C' are connected as before by the rod F one end of
which forms the strap of an eccentric E fixed to the shaft H mounted in the arm C
and provided with a hand lever G, the other end of the connecting rod F passing
through a socket "pivoted to the arm C¹ so as to accommodate itself to the
angular movement of the rod F. The end of the rod F is screw-threaded and
provided with a nut m at the inner side of the socket f¹ and with a hand-wheel R
at the outer end, a spiral spring D being interposed between the hand-wheel and
the socket and compressed more or less by the hand wheel to permit of a more or
less yielding pressure.
A second rod F pivoted to the eccentric connects the
latter with an arm or stay on the end frame N, thus giving a positive point of
resistance whereby to ensure the simultaneous and equal motion of the presser
plates.
In Figure 4 the ends of the connecting rod F are reversely screw-threaded and
work in nuts ff pivoted to the upper ends of the two arms C C¹ so as to
accommodate themselves to the angular motions of the arms. By means of bevel
wheels W, shaft H, and winch handle R, the rod F can be rotated in either

In Figure 5 the connecting-rod F is pivoted to the arm (" and to the short
arm E of an elbow-lever E G fulcrumed on the arm C and held in position for
applying pressure by a rod F¹ connected with a weighted lever J, the said rod FI
being adjustable as to its length by means of a right and left screw coupling and
connected to the hand lever G by a hook so as to admit of being unhooked to

presser plate B² may be arranged below the cylinder, as shewn in dotted lines, and
be pressed against the cylinder independently of the other two, by means of a
weighted lever J' K.
A third
In Figure 7 the upper ends of the two arms C Care connected by a rod F made
in two parts coupled by right and left screw threads and a nut for adjusting its
length, a worm wheel in one with the nut being in gear with a worm turned by
a hand wheel. The stud c at the lower end of the arm C is supported in a slot in
the foot of the frame N and is connected by a toggle-joint E E' with the hand
lever G fast upon shaft H by turning which the toggle may be straightened and
brought into position to exert pressure. The shaft H extends from end to end of
the machine and is journaled in the short arm of the weighted elbow-lever J
hereby a yielding pressure is obtained.
In Figure 8 the connecting rod F is jointed at one end to an elbow E formed
with a toothed segment with which gears a pinion r upon the shaft H which is
turned by a hand wheel G for moving the arms C C to or from the cylinder. The
connecting rod F is jointed at its other end to an elbow lever g pivoted to the
arm C and connected with the weighted lever J through a rod F¹ whereby a
yielding pressure is obtained. Two screw stops k k¹ in bracket arms M M¹ on the
end frame N limit the outward motion of the arms C C¹.
In Figure 9 the connecting rod F is jointed at one end to arm C¹ and at the
other to the hand lever G having an elbow E connected with the arm C through
the interposition of a weighted elbow lever T fast upon the shaft H mounted in
arm C for the purpose of giving a yielding quality to the pressure.
Instead of mounting both presser-plates in pivoted arms one of them B may
slide in a guide way P, as in Figure 10, while the other B¹ is arranged in the usual
manner in the lever arm C the two being connected by a rod F and arm E which
is fast upon the shaft H. The rod F is arranged in the middle of the machine
below the cylinder and is curved so as to act as a spring and give a yielding
pressure.

In Figure 11 a pressing machine is shewn with three presser plates, two B B¹ being
arranged on opposite sides of the cylinder A mounted in pivoted arms and adjusted
in the manner shewn in Figure 6. The third presser plate B2 is placed below the
cylinder and its journal slides in guide-ways P and being formed with a projection ƒ³
against which a toggle-joint E¹ E' acts so as to cause the presser-plate to move up
or down within the guide-way. F is a rod connecting the middle joint of the
toggle with the lower extremity of the arm C so that any motion of the said arm
will be communicated to the third presser plate whereby all three presser-plates
will be moved simultaneously to or from the cylinder. In order to obtain a
yielding pressure the arm C is pivoted to a weighted lever J' fulcrumed in the
frame N, a second weighted lever J' being connected with the toggle-joint E¹ E'.
In case it should be required to operate the lower presser-plate independently of
the other two, the connecting rod F' may be attached to a hand lever G¹, as shewn
in dotted lines.

page_text: Figure 12 shews three presser plates, the two opposite ones B B₁ being journaled
in the arms C C and the third mounted in an arm C2 pivoted to the frame N and
placed below the cylinder. The arms C C¹ are connected by rods F F and elbow-
lever EG, an O-shaped loop or hanger E' being connected to the middle joint of
the rods F F and to the journal of the presser plate 13' whereby the latter is
suspended and brought into connection with the other two. By raising the hand-
lever G the presser plate B' is free to descend by its own weight until it rests on
the stop M whereupon the vertical arms are drawn back from the cylinder, so
that all three presser-plates are actuated by one movement of the hand lever.
In Figures 13, 14, and 15, the third presser plate B is stationary while the
cylinder A is pressed upon it, being journaled in bearings S sliding in guides P of
the end frame N.
In Figure 13 a toggle joint E E' is connected to the bearing of the cylinder and
to the middle joint of the rods F F which are pivoted to the arms C C and formed
each with a loop for allowing of a yielding pressure. The lower link E' of the
toggle-joint has a hand lever G for operating it. By straightening the toggle-joint
the cylinder is forced down on to the lower presser plate B and the arms C C¹ are
drawn towards the cylinder. By the reverse movement the arms C C₁ are drawn
back from the cylinder until they bear against the screw-stops k in bracket
arms M M' whereupon further flexure of the toggle causes the cylinder to be raised
from the lower presser-plate.
In Figure 14 the movement of the presser-plates B B³ and the cylinder A is
similar, but the arms C C¹ in which the presser plates B B are journaled are
curved and pivoted upon a common axis. A connecting rod F' made in two parts
united by a right and left screw-coupling is pivoted at the lower end to the
bearing S of the cylinder A and at the upper end to the middle joint of the
rods FF connecting the arms C C¹ and formed with loops to afford a yielding
pressure, the rod F terminating in a strap embracing an eccentric E fast upon the
shaft H. When the eccentric is turned in one direction by the movement of the
hand-lever G fast on shaft H the arm C is drawn back first until it bears on
the stop k, then the other arm C is moved away from the cylinder until it bears
against the stop k', and lastly the cylinder is raised from the third presser-
plate B².
Conversely when pressure is to be exerted the cylinder goes down first
owing to its weight and the arms C¹C then move inwards to press their plates
against the cylinder.
Figure 15 shews a double-armed lever E' E' fast upon the shaft H to the
opposite ends of which the arms C C¹ are connected by the yielding rods F F¹, the
connections being between the swinging arms C C and the lever arms E' E'
respectively as shewn. The shaft H is mounted in the frame N and is operated by
a hand lever G, and carries an eccentric E which is connected with the bearing of
the cylinder A through the rod F2 so that by turning the hand-lever G the presser-
plates B B are drawn back from the cylinder and the cylinder is raised by means
of the eccentric. The presser plates B B are arranged somewhat above the
level of the axis of the cylinder so as to be pressed obliquely downwards against
the cylinder whereby to increase the pressure of the cylinder against the lower
plate.
For the purpose of giving a yielding quality to the pressure, each arm C and C¹
may be connected with a weighted lever J as before described. In these pressing
machines a sheet metal jacket is to be applied between the presser-plates and the
cylinder, and it is to be understood that all the presser-plates of a machine may be
connected by one jacket only, or each may have a separate jacket, or the sheet-
metal jacket may be omitted entirely.
