PROVISIONAL SPECIFICATION.
Improvements in or connected with Hydraulio Packing Presses.
We, HENRY SHIELD and WILLIAM CRITOHLEY, both of 17, York Street,
Liverpool; in the County of Lancastor, Engineers, do hereby declare the nature of
this invention to be as follows :-
This invontion has reference to hydraulic presses for compressing loose cotton
and other fibres, and other goods; and has mainly for its object to provide in
connection with the packing of goods, which are pressed and bound, means by
which the cutting of the goods in the press, which frequently occurs in presses
employing grooved "lashing plates," due to the great pressures used, shall be
obviated.
Under this invention, the lashing plates are so constructed, or arrangements or
provisions are mado, by which the pressing surfaces of the upper and lower
"lashing plates" of the press are even or smooth, or practically so, during tho time
the material is being pressed; the construction and arrangement being at the same
time such that the hoops or bands can be passed outside round the bale when the
compression is completed, or in some cases, during compression.
In one arrangement for effecting this end, we employ in the press top and bottom
lashing plates with a series of channels through them, in which work bars which
are alternately moved up to the surface of the plate, rendering such surface even,
and away from it, rendering it of grooved form. Through the grooves, the hoops
or bands may be passed after the goods are compressed. These bars we call
Gilling-bars." At the back of these "filling-bars," are bars which are adapted to
be moved to and fro and which actuate the aforesaid "filling-bars." In the upper
lashing plate the "filling-bara" and lashing plate itself are provided with cross hars
or bolts, between which the actuating bars work, and such bars being provided
with inclines or inolined parts, and acting ou said cross bars or bolts, will, when said
actuating bars are moved to and fro, cause the "filling-bars" to be lifted out of the
grooves, and lowered into same. The cross bars or bolts by which the raising of
the actuating bars is effected, are fixed in the lashing plate, the others being fixed
in the "filling-bars."
Between the actuating bars and the filling-bars we employ other bars with
inclined edges, acting in connection with inclines in the lashing plate and the
actuating bar, by which the filling-bars are rigidly locked when filling the grooves
in the lashing plate, and rendering it even in surface, but which are moved, through
such inclines, into the recesses in the lashing plate, in which the netuating bars
work, when the surface bars are raised.
In the lower lashing plate, the actuating bars are provided with inclined parts at
each end, and work in connection with the inalined surfaces at each side of the
lashing plate. All the parts are disposed within the planes in which the outer sides
and ends of the lashing plate lie, so that it can be moved up into the baling, filling,
or other boxes without hindrance. These bars are locked by a locking device, such
as a locking bar running transversely to their direction of length. To lower the
filling-bars" out of the lashing plate grooves, they are pulled out by a hook, or
other tool, singly or in multiple. This tool may be adapted to pass in under said
bars, and catch a toe on the end thereof, or similar or equivalent provisions may be
provided for this purpose. By moving the actuating bar inwards, the filling-bara
are raised, and the surface of the lashing plate rendered even, this action may be
done by hand.

As an alternative arrangement for carrying out this invention, we may use
grooved lashing plates, the grooves in this case, however, being covered, and the

page_text: surface of such plates rendered practically even, aufficient to prevent cutting of the
goods when being pressed, by the employment of pieces or strips of iron or steel
covering the grooves. When binding, these pieces or strips of iron or steel are
caught between binding hoops or wires which is or are passed through the grooves.
To illustrate the nature of our invention, examples of one construction thereunder,
and as above specified, are given in the accompanying drawings.
In the drawings:
Figure 1 is a section shewing the bars of the upper lashing plate in longitudinal
elevation, such bars being down; Figure 2 is a cross section of same;
Figure 3 is a similar view to Figure 1, shewing the bars moved up; Figure 4 is
a cross section of same;
Figure 5 is a plan of Figure 1;
Figure 6 is a section showing the filling bars of the lower lashing plato in
longitudinal elevation, in their upper position; Figure 7 is a cross section; and
Figure 8 an outside elevation of same.
Figure 9 is a section shewing the filling bars of the lower lashing plate in
longitudinal elevation, said filling bars being shewn in their lower position.
Figures 10 and 11 are respectively cross section and outside end view of same.
Referring to Figures 1, 2, and 3, a is the base or body of the lashing plate.
The face or surface of the base consists of plates b attached thereto by screws or
other means. care the channels in the base a. d are the filling-bars, which are
Tshaped in section, the web filling the grooves or spaces between the sides of the
plates b, when in their lowered position. It will be observed that the lashing-plate
surface plates 6 are very wide, relatively with the filling-bars d, or the parts
thereof which fill the spaces between them. The lashing plates or bases thereof
are, as will be seen, made solid or in one piece. e are the notuating bars the under
surface of which is bevelled. are the locking bars, which are bevelled at their
upper surface in two directions, the inner bevels working in connection with
the bevel on the underside of the actuating bars e, whilst the outer bevels work in
connection with the bovels in the lashing plate channels or recesses c.
9 are lifting bolts or bars, they being fixed in extended parts on the lashing
plate, and on which the inclined parts e of the actuating bars e act; and are
bolts or pins fixed in the upwardly projecting parts d' of the filling-bars d, and in
contact with which the back of the actuating bars e comes when they are pulled
out, and whereby the filling-bars d are lifted up ont of the spaces between the
plates b, and grooves formed in the lashing plate.
In action, when the filling-bars d fill the spaces between the plates b, they are
held in position by the actuating bar e, which holds the looking bars f, in the
position shewn in Figures 1 and 2. In this position, when pressure comes upon the
bar d, in pressing goods, it is transmitted to the lashing plate a through the bars f,
which are prevented from moving inwards by the bar e When, however, the
filling-bars d are moved into their upper position, for the purpose of allowing
hoops to be passed round the bale, after the goods have been compressed, the barse
are pulled out-singly or in multiple-by a suitable tool ', or by hand; by which
action through the inclined planes or parts e' at each end, acting on or in connection
with the bars or bolts g, the bars e are raised, and through the pins & of the filling
bars & being in turn acted upon by the upper side of the bars e, said filling-bars d
are raised. This lifting action, first moves the bare from between the bars f,
before d lifts, but when e is a certain height up, the bar d is raised, and the inclined
surfaces of the bars f, coming in contact with the inclined surfaces of the lashing
plate a, they are pressed inwards and take the position shewn in Figure 4.
In the lower lashing plate shewn in Figures 6 to 11 the filling-bars d do not
require positive action when being moved out of the spaces between the plates b,
but only require positive motion when being moved into said spaces. The actuating
bars e in this case have inclined planes e' at each end, which work on inclined planes
formed in the bottom of the recesses c; and as they are moved in one direction or
the other, they are raised or fall; and through the bars f, in a like manner as set

page_text: forth with reference to the upper lashing plate, they move the filling-bars & into
the spaces between the plates b, and out of same. A toe is formed at one end of
the actuating bars e, under which a tool, such as ' shewn in Figure 6, may be
introduced, and by which the bars are drawn out before passing the bands or hoops
under the bale.
A locking dovice is used in connection with the bars e in this case. A suitable
locking device for this purpose may consist of a bar i, having gaps therein, and so
arranged, that by turning it or otherwise moving it, the barse are free to move
outwards and downwards. As will be seen in the drawing, this bar lies partly in
the inclines e, aud partly in the inclined parts at the bottom of the channels c of
the lower lashing plate a.
Plates are provided in connection with the lashing plates to hold the bars d
audin position endwise, and by which, by romoval, access to the internal parts
can be had.
It will be seen by removing the plates b, all the bars within the channels o can
be easily removed, and, vice versa, introduced.
The surface of the lashing plates a may be straight or flat as shewn in the
drawings, or curved, if desired.
It is to be understood that the invention with respect to the employment of
movable bars, alternately rendoring lashing plates of hydraulic presses even or
smooth and grooved, as set forth above, it is not restricted to the precise forms or
constructions of parts set forth with reference to and shewn in the drawings, since
these may be varied or modified without departing from the legitimate scope of this
invention.

COMPLETE SPECIFICATION.
Improvements in or connected with Hydraulio Packing Presses.
Wo, HENRY SHIELD and WILLIAM CRITOHLEY, both of 17, York Street,
Liverpool, in the County of Lancaster, 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 :—
This invention has reference to hydraulic presses for compressing loose cotton
and other fibres, and other goods; and has mainly for its object to provide in
connection with the packing of goods, which are pressed and bound, means by
which the cutting of the goods in the press, which frequently occurs in presses
employing grooved "lasbing plates," due to the great pressure used, shall be
obviated.
Under this invention, the "lashing plates" are so constructed, or arrangements
or provisions are made, by which the pressing surfaces of the upper and lower
"lashing plates" of the press are even or smooth, or practically so, during the
time the material is being pressed; the construction and arrangement being at the
same time anch that the hoops or bands can be passed outside round the bale
when the compression is completed, or in some cases, during compression.
In one arrangement for effecting this end, we employ in the press top and
bottom lashing plates with a series of channels through them, in which work bars
which are alternately moved up to the surface of the plate, rendering such surface
even, and away from it, rendering it of grooved form. Through the grooves, the
hoops or bards may be passed after the goods are compressod. These bars we
call "filling bars." At the back of these "filling-bars," are bars which are
adapted to be moved to and fro and which actuate the aforesaid "Alling-bars."
In the upper "lashing plate" the "filling-bars" and "lashing plate" itself are·

page_text: provided with cross bars or bolts, between which the actuating bars work, and such
bars being provided with inclines or inclined parts, and acting on said cross bars
or bolts, will, whon said actuating bars are moved to and fro, cause the
"filling-bars" to be lifted out of the grooves, and lowered into same.
The cross
66
bars or bolts by which the raising of the actuating bars is effected, are fixed in
the "lashing plate," the others being fixed in the "filling-bara."
Between the actuating bars and the "filling-bars wo employ other bars with
inclined edges, acting in connection with inclines in the "lushing plato" and the
actuating bar, by which the "filling-bars" are rigidly locked when filling the
grooves in the lashing plate," and rendering it even in surface, but which are
moved, through Buoh inclines, into the recesses in the "lashing plate," in which
the actuating bars work, when the surface bara are raised.
In the lower "lashing plate," the actuating bars are provided with inclined
parts at each end, and work in connection with the inclined surfaces at each side
of the "lashing plate." All the parts aro disposed within the planes in which the
outer sides and ends of the "lashing plate" lie, so that it can be moved up into
the baling, filling, or other boxes without hindrance. These bars are locked by a
locking device, such as a locking bar running transversely to their direction of
length. To lower the "filling-bars" out of the "lashing plate" grooves, they are
pulled out by a hook, or other tool, singly or in multiple. This tool may be
adapted to pass in under said bars, and catch a toe on the end thereof, or similar
or equivalent provisious may be provided for this purpose. By moving the
actuating bar inwards, the "filling-bars are raised, and the surface of the
"lashing plate" rendered even, this action may be done by hand.
As an alternative arrangement for carrying out this invention, we may use
grooved "lashing plates," the grooves in this case, however, being covered, and the
surface of such plates rendered practically even, sufficient to prevent cutting of
the goods when being pressed, by the employment of pieces or strips of iron
or steel covering the grooves. When binding, these pieces or strips of iron or
steel are caught between binding hoops or wire which is or are passed through the
grooves.
To illustrate the nature of our invention, examples of one construction there-
under and as above specified are given in the accompanying drawings.
Figure 1 is a section shewing the bars of the upper lashing plate in longitudinal
elevation, such bars being down; Figure 2 is a cross section of same;
Figure 3 is a similar view to Figure 2, shewing the bars moved up ;
Figure 4 is a plan of Figure 1 ;
Figure 5 is a section shewing the filling bars of the lower lashing plato in
longitudinal elevation, said filling bars being shewn in their lower position.
Figures 6 and 7 are respectively cross section and outside end view of same.
Keterring to Figures 1, 2, and 3, a is the base or body of the "lashing plate."
The face or surface of the base consists of plates b attached thereto by screws or
other means. c are the channels in the base a. d are the "filling-bars," which are
Tshaped in section, the wab filling the grooves or spaces between the sides of
the plates b, when in their lowered position. It will be observed that the
"lashing plate" surface plates 6 are very wide, relatively with the "filling-bars" d
or the parts thereof which fill the spaces between them. The "lashing plates
or bases thereof are, as will be scen, made solid or in one piece. e are the actuating
bara, the under surfaces of which are bevelled. fare the locking bars, which are
bevelled at their upper surface in two directions, the inner bevels working in
connection with the bevel on the underside of the actuating bars e, whilst the
outer bevels work in connection with the bevels in the "lashing plate" channels
OT recesses o.
9 are lifting bolts or bars, they being fixed in extended parts on the
"lashing plate," and on which the inclined parts of the actuating bars e act;
and are bolts or pins fixed in the upwardly projecting parts d' of the
filling-bars” d, and in contact with which the back of the actuating bars e
86

page_text: "
comes when they are pulled out, and whereby the "filling-bars" d are lifted up
out of the spaces between the plates b, and grooves formed in the "lashing plate."
In action, when the "filling-bars" fill the spaces between the plates b, they
are held in position by the actuating bar e, which holds the locking bars f in the
position shewn in Figures 1 and 2. "In this position, when pressure coines upon the
bar d, in pressing goods, it is transmitted to the "lashing plate a through
the bars which are prevented from moving inwards by the bar e.
When,
however, the "filling-bars" d are moved into their upper position, for the purpose
of allowing hoops to be passed round the bale, after the goods have been
compressed, the bars e are pulled out-singly or in multiple--by a suitable tool h',
or by hand; by which action through the inclined planes or parts e' at each end,
acting on or in connection with the bars or bolts g, the bars e are raised, and
through the pins h of the "Alling bars" d being in turn acted upon by the upper
side of the bars e, said "filling-bara "d are raised. This lifting action first moves
the bar e from between the bara f, before d lifts, but when e is a certain height up,
the bar dis raised, and the inclined surfaces of the bars, coming in contact
with the inclined surfaces of the "lashing plate" a, they are pressed inwards and
tako the position shewn in Figure 3.
B
In the lower lashing plato shown in Figures 5, 6 and 7, the "filling-bars" d do
not require positive motion when being moved out of the spaces between the
plates 6, but only require positive motion when being moved into said spaces. The
actuating bars in this case have. inclined planes e' at each end, which work on
inclined planes formed on the bottom of the recesses o; and as they are moved in
ono direction or the other, they are raised or fall; and through the bars, in a like
manner as set forth with reference to the upper "lashing plate," they move the
filling-bars" d into the spaces between the plates b, and out of same. A too e' is
formed at one end of the actuating bars e, under which a tool, such as A! shown
in Figure 5, may be introduced, and by which the bars are drawn out before passing
the bands or hoops under the bale.
"
A locking device is used in connection with the bars e in this case. A suitable
locking device for this purpose may consist of a bar i, having gaps therein, and so
arranged, that by turning it or otherwise moving it, the barse are free to move
outwards and downwards. As will be seen in the drawing, this bar lies partly in
the inclines e', and partly in the inclined parts at the bottom of the chanuels c of
the lower "lashing plate" a.
Plates are provided in connection with the "lashing plates" to hold the bara d
and in position endwiso, and by which, by removal, access to the internal parts
can be had.
It will be seen by removing the plates b, all the bars within the channels o can bo
easily removed, and, vice versa, introduced.
The surfaces of the "lashing plates" a may be straight or flat, or curved, if
desired.
The chief advantages afforded by this invention, and its main novel features,
may be summarised as follows:-1. The surface of the plates, d, is made as narrow
as possible, consistent with the provision of sufficient space to enablo a substantial
hoop to be passed through; namely, they are much narrower than the fixed
strips, b, of the "lashing plates," theroby rendering the surface of plate, d, or bars
exposed to the bale and pressure small, and keeping the pressure on the working
parts small, enabling them to be easily operated, and rendering the wear small.
2. The fixed portions of the surface, of the "lashing plates" are made separable
from the bodies thereof, and are normally secured thereto by screw studs or the
like, whereby, as or when desired, access is quickly had to the interiors of the
grooves for examination, cleaning, repairs, or other object or end. 3. The "lashing
plate" bodies are each made in one piece, with grooves in them in which the
working parts lie; and upon the upper edges of the divisions or partitions the
plates, b, are fixed. 4. With regard to the lower plate, particularly, with its
operating parts, it is so constructed and arranged that no parts project beyond the

page_text: sides of the plate when ready for pressing goods, and thus it is adapted to be usod
for pressing goods within a baloing or filling box, enabling it to rise through such
box in the act of pressing.
It is to be understood that the invention with respect to the employment of
movablo bars, alternately rendering "lashing plates" of hydraulic presses even or
smooth and grooved, as set forth above, is not restricted to the preciso forms or
constructions of the parts shown in the drawings, since these may be varied
or modified without departing from the legitimate scope of this invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what mannor the same is to be performed, we declare that what we
claim is :-
The heroin described improvements in or connected with hydraulic packing
presses, that is to say, the improved constructions and arrangements of parts of
lashing plates" having movable bars for the purposes specified; substantially as
herein set forth.
