Improvements in or connected with Cotton, Jute, and other similar
Presses.
We, HENRY SHIELD, of 17, York Street, Liverpool, in the County of Lancaster,
Engineer, and JAMES ANDERSON, of Craiginnan Lodge, Dollar, Clackmannanshire,
N.B., Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference, more particularly, to hydraulic presses, for
pressing materials, such as cotton, jute, hemp, and other materials, to enable
them to be packed in a compressed or closely packed form for transit; and it
has, primarily, for its object to provide improvements in connection with certain
kinds of presses, as the kind generally called a grid press," by which the bales
made or pressed in the machine, shall, under all circumstances, be substantially
truly rectangular in cross section; or in other words, by which it-the machine
shall not be liable to produce or turn out bales of a form with one side deeper
or greater than another, as frequently happens with the kind of press referred to,
as at present constructed and used.
The desirability of turning out or producing bales of substantially truly rect-
angular form, chiefly arises out of the question of close stowage of bales for
transit: as, obviously, if the bales are substantially rectangular, they will stow
closely and neatly; whereas if they are irregular, in the directions referred to,
greater space is occupied for a given number, and the cost of transit is larger
in consequence.
According to the present invention, in its application to the presses of the kind
referred to,i.c., a press in which the cotton or material is first pressed into a
box, and then held up by a grid, and the finishing is effected by an upper set
of finishing rams and follower, with the main doors of the box open-the finishing
ram follower is guided at its sides in its descent, and is prevented from moving
er canting laterally out of the desired vertical direction or position during the
act of pressing and baling; this being effected by means of slides and guides
or constractions as hereafter described, by which side movement or cant of the
follower is absolutely prevented while the finishing, pressing, and baling opera-
tions are going on; and the production of deformed bales is entirely obviated.
The invention is applicable alike to existing, presses of the kind referred to,
and to new presses; that is to say, it can be applied as an attachment to existing
presses, whilst in the case of new presses, the press would, in some points, be
preferably modified, or specially constructed, with the improvements applied;
and in these different cases, the means or constructions adopted will differ
materially as to form. However, it is not absolutely necessary that old presses
should be fitted with the attachment referred to, as they could, if desired, be
modified and be provided with the improved construction which would be normally
used in the case of the application of the invention to new presses, as referred
to or vice versu

For convenience of description, the invention will be first described as applied
to existing presses of the kind referred to; that is, as an attachment.
follower of the finishing rams is a comparatively deep body of a size and form
corresponding with the size of the box in which the bale is formed; and at its
upper part it is generally formed with heavy overhanging flanges at each side.
To the lower part or body of this follower, and at each end of it, special brackets
are fitted, which act as slides; and onto the outside of the corner columns of
the press, there are attached stout bars, which act as guides to the slides; these
bars being disposed opposite the lower part of the follower. The inside surfaces
of these bars are a greater distance apart than the over all width of the over-
hanging flanges of the follower; and the brackets are carried out to project
beyond these overhanging flanges, and bear upon the bars. The relative positions
of the bars in relation to the follower, laterally, is employed in order to enable
the follower to be lowered right down, and the overhanging parts to pass between
the guide bars, for the purpose of enabling the cup leathers of the finishing rams
to be exposed, and new ones placed in, without having to move any of the parts.
These guide bars are conveniently held or attached to the columns of the press
by bolts, which pass through them, and on each side of the column, clamping
them on.
In connection with this construction, and application of the invention, we
employ, in some cases, an automatically controlling device, which acts upon the
hydraulic service or pressure water in such a manner, that the finishing rams
can not be pressed down or brought into action so long as either of the main
doors of the press box is not fully open; and the control is effected by operating
or controlling a valve connected with the finishing ram cylinders, through the
main doors of the press. In one arrangement, this action is effected by a lever
or levers, operated by the doors and so arranged and adapted to act, that while
either door is not fully opened, and thus in a position which will allow the
brackets on the follower to come in contact with it, the valve referred to is not
actuated, i.e., remains open, and the finishing rams cannot be operated. In order
that this action may be dependent upon both doors, there is provided for each
door, and operated by it a mechanism, so adapted, that, until both these mechan-
isms are operated, the valve referred to cannot operate, or is kept locked. One
form of such device consists of a lever or slide actuated from each door, and
provided with a niche or recess (or projections) operating in connection with a
valve rod; and so arranged, that until this valve rod moves into or engages
with the niches (or is operated by the projections) of both slides, the valve is not
actuated; and thus both doors must be completely open and clear of the path
of the brackets on the follower, before it the follower-can descend.
As a modification of the automatic means above described, by which the descent
of the follower is automatically prevented from taking place until the main
doors are completely open, and clearly out of the path of the brackets on the
follower, there is employed in connection with the valve controlling the supply
of pressure water to the rams, a brake mechanism, controlled by the position
and action of the doors, in such a manner, that unless both the doors are wide
open, the brake mechanism will be " on," and the valve "locked shut." When,
however, the doors are completely open, the brake is automatically taken "off
by the action of the doors.
"
One form of this automatic controlling mechanism consists in having upon,
or geared with, the pressure water valve actuating spindle, a brake friction disc,
standing, say, above the head of the press, horizontally, and supported by a
bracket; while in connection with it, there are two separate brake blocks or
shoes, and sets of levers and rods, with tappets, which are actuated by a part
of the doors, or provision thereon, when fully open. One of these sets of parts
acts in connection with one door, and the other set with the other door. The
brake blocks or shoes are guided by the brake pulley supporting bracket, and
each block is worked by a separate bell crank, supported from the opposite

page_text: corners of the press head; and these bell cranks are operated from the two doors
independently, through tappets supported on shafts on the columns, and levers
and vertical weighted connecting rods. The action is, that when the doors, or
either of them, are in any other position than full open, the tappets are free, and
the weights pull down the upper bell cranks, and press the brake shoes or blocks
into the brake pulley; and so long as either of these blocks or slides is "on,"
the pressure water valve actuating wheel or handle cannot be operated; that
is, the valve is "locked shut." When the doors are both fully open, they act
upon the tappets, as stated, and release the brake mechanism, and so enable the
valve to be opened.
In the case of a new press, constructed according to this invention, or pro-
vided with these improvements, guides, in the form of brackets, would be fixed
on the columns (which would have special provisions formed upon them to receive
and carry the brackets); while the follower would have on its sides at each end,
vertical facings, which would bear upon, and slide over the ends of the brackets.
Or, in other cases, these guides or brackets would be in the form of horns or pro-
jections constructed on, and forming a part of, the columns of the press.
In some cases, where at the upper part of the follower, there is an overhanging
drain saucer, and where it is desired to occasionally bring the follower down
past the guide brackets, so as to obtain access to the cup leathers of the rams
for renewal etc.. the brackets would be provided with moveable facing blocks,
the back faces of which would project or stand at a point outside the path of the
follower drain saucers referred to; so that by moving these blocks out of the way,
the follower could be lowered past the brackets, as referred to; otherwise, it
could not be so lowered, as normally a part of the brackets would lie in the path
of the saucers, when the rams were lowered for the special purpose referred to.
One mode of arranging and constructing these moveable face blocks is by
mounting them on hinges or pins at the top of the brackets, and adapting them to
revolve about these hinges in the plane of their own faces and the facings of the
followers. When they are moved up, and thrown back about their hinge sup-
ports, they will be clear of any part of the follower and on the other hand, when
they are down, they fill the space between the brackets proper and follower
facings; and they rest upon the upper edge of the brackets by a flange or pro-
jection on them. Lock bolts are provided in the brackets to hold the moveable
facing blocks in position; and through bolts, connecting and staying together,
the pairs of brackets at the two ends of the press, are provided.
In this case there are no projecting parts on the follower to come in contact
with the main press doors, whether closed or open; and therefore the automatic
controlling valve and arrangement above specified is not required.

Improvements in or connected with Cotton, Jute, and other similar
Presses.
We, HENRY SHIELD, of 17, York Street, Liverpool, in the County of Lancaster,
Engineer, and JAMES ANDERSON, of Craiginnan Lodge, Dollar, Clackmannanshire,
N. B., Engineer, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This invention has reference, more particularly, to hydraulic presses, for

referred to, i.e., a press in which the cotton or material is first pressed into a

of finishing rams and follower, with the main doors of the box open-the finishing
ram follower is guided at its sides in its descent, and is prevented from moving
or canting laterally out of the desired vertical direction or position during the

or constructions, as hereafter described, by which side movement or cant of the
follower is absolutely prevented while the finishing, pressing, and baling opera-
tions are going on; and the production of deformed bales is entirely obviated.

should be fitted with the attachment referred to, as they could, if desired, be
modified, and be provided with the improved construction which would be normally
used in the case of the application of the invention to new presses, as referred
to or vice versa.
For convenience of description, the invention will be first described as applied
to existing presses of the kind referred to; that is, as an attachment. The
follower of the finishing rams is a comparatively deep body of a size and form
corresponding with the size of the box in which the bale is formed; and at its
upper part it is generally formed with heavy overhanging flanges at each side.
To the lower part or body of this follower, and at each end of it, special brackets
are fitted, which act as slides; and onto the outside of the corner columns of
the press, there are attached stout bars, which act as guides to the slides; these
bars being disposed opposite the lower part of the follower. The inside surfaces
of these bars are a greater distance apart than the over all width of the over-
hanging flanges of the follower; and the brackets are carried out to project
beyond these overhanging flanges, and bear upon the bars. The position
of the bars in relation to the follower, laterally, is employed in order to enable
the follower to be lowered right down, and the overhanging parts to pass between
the guide bars, for the purpose of enabling the cup leathers of the finishing rams
to be exposed, and new ones placed in. These guide bars are conveniently held

As a modification of the automatic means above described, by which the descent
of the follower is automatically prevented from taking place until the main
doors are completely open, and clearly out of the path of the brackets on the
follower, there is employed in connection with the valve controlling the supply
of pressure water to the rams, a brake mechanism, controlled by the position
and action of the doors, in such a manner, that unless both the doors are wide

In the case of a new press, constructed according to this invention, or pro-
vided with these improvements, guides, in the form of brackets, would be fixed
on the columns (which would have special provisions formed upon them to receive
and carry the brackets); while the follower would have on its sides at each end,
vertical facings, which would bear upon, and slide over the ends of the brackets.
Or, in other cases, these guides or brackets would be in the form of horns or pro-
jections constructed on, and forming a part of, the columns of the press.
In some cases, where at the rpper part of the follower there is an overhanging
drain saucer, and where it is desired to occasionally bring the follower down
past the guide brackets, so as to obtain access to the cup leathers of the rams

page_text: for renewal etcetera, the brackets would be provided with movable facing blocks,
the back faces of which would project or stand at a point outside the path of the
follower drain saucers referred to; so that by moving these blocks out of the way,
the follower could be lowered past the brackets, as referred to; otherwise, it
could not be so lowered, as, normally, part of the brackets would lie in the path
of the saucers, when the rams were lowered for the special purpose referred to.
One mode of arranging and constructing these movable face blocks is by
mounting them on hinges or pins at the top of the brackets, and adapting them to
revolve about these hinges in the plane of their own faces and the facings of the
followers. When they are moved up, and thrown back about their hinge sup-
ports, they will be clear of any part of the follower; and on the other hand, when
they are down, they fill the space between the brackets proper and follower
facings; and they rest upon the upper edge of the brackets by a flange or pro-
jection on them. Lock bolts are provided in the brackets to hold the movable
facing blocks in position; and through bolts, connecting and staying together,
the pairs of brackets at the two ends of the press, are provided.
In this case there are no projecting parts on the follower to come in contact
with the main press doors, whether closed or open; and therefore the automatic
controlling valve and arrangement above specified is not required.
The improvements under this invention are illustrated in the accompanying
drawings. In these drawings, Figure 1 is a side elevation; Figure 2 an end
elevation; and Figure 3 a plan in section of a grid provided with our improve-
ments.
Figures 4, 5, and 6, are, respectively, side elevation, plan, and end elevation,
illustrating in detail the slides and guide bars above referred to, and shewn also
in Figure 1.
Figures 7 and 8 are side elevation and plan illustrating our new or improved
guides or guiding devices for the follower, applied more particularly to a new
press.
Figures 9 and 10 are side elevation and plan, respectively, illustrating the
safety mechanism connected with the finishing rams and doors of the press.
Referring in the first instance to Figures 1 to 6, a is the box into which the
cotton or material is first pressed, b is the grid which is introduced under this
cotton, and by which it is held up when under the action of the finishing rams, c are
the two main closing doors, forming sides to the box a, d are the finishing rams,
and e a follower operated by these rams, f is the head of the press in which the
cylinders of the rams d are contained; and h are the columns connecting this
head with the base. is the lifting cylinder for the rams d and follower e, ¹ being
side rods connecting the plunger of this cylinder with the projecting or over-
hanging parts e¹ of the follower.
As will be seen, the body of the follower e is comparatively deep, and of a
form and size corresponding with those of the box a, in which the bale is formed;
while at its upper part, the overhanging flanges el exist.
According to this invention, the follower e is guided while it is pressing the
material in the box a, with the main door e open; and k are the guide bars, and
7 the slide brackets, by which this is effected. In the construction shewn in
the figures referred to, (which shew our improvement applied to an existing
press) the brackets are secured to the columns h by bolts k¹, by which these bars
are clamped onto the outside of the columns, and so that they are wider apart
than the width of the follower across the overhanging portions or upper part e¹.
This enables the follower to be dropped or pressed completely through and be-
tween these guides when desired. The brackets are secured-say by bolts-to
the sides of the follower e, below the upper overhanging portion; and their outer
faces (as well as the inside surface of the guide bars k) are tooled or faced. It
will be seen, these guides k, and slide brackets 1, will prevent the canting of the
follower e, when pressing the cotton with the side doors c open; and thereby the
press is caused to produce bales of truly rectangular form.

page_text: In the modification shewn in Figures 7 and 8, which illustrate the application
of our improvements to a new press, the guides are secured onto special in-
wardly projecting provisions h¹, formed on the columns h. In this case, the
guides bear directly on, and guide the followers e at the four corners of the sides,
which form the slides to the follower. To enable the follower e to pass com-
pletely past the guides k, for renewing the cup leathers, or other object, the
guides are provided on their inner faces with hinged movable faces hinged
at eccentrically to the centre of the slide. It will be seen by Figure 8, that
when the liners are in the position for use, the overhanging parts e (which are
the drain saucers to the ram) on the upper part of the follower lie above a por-
tion of these movable faces, and that therefore the follower cannot be moved
down while the faces are in the normal position, so that, to enable this to be done,
the faces have to be first swung up out of position, when the foot portion, which
lies in the path of the parts e² of the follower, is moved out of this path. When
the liners are in working position, they are fastened by a stud bolt k, which
passes through the brackets and is tapped into the faces. When the faces are to
be turned up, these tap bolts are withdrawn.
In the construction first described, the brackets on the follower might come
in contact with the main pressed doors if closed, or only partly open. To pre-
vent this, special arrangements connected with the fluid pressure system are pro-
vided; but in the construction last described, there are no projecting parts to
come in contact with the main press doors; and, therefore, the automatic arrange-
ments (hereafter described in connection with the former apparatus) are not
required.
Referring now to this automatic controlling mechanism, just referred to, which
is employed in connection with the construction set forth with reference to and
shewn in Figures 1 to 6, this is illustrated in Figures 1, 2, and 3; while a modifi-
cation of it is shewn in Figures 9 and 10. As stated, this mechanism is so
adapted that the finishing rams d cannot be pressed down or brought into action
so long as either of the main doors c of the press box a is not fully open; and so
that they are completely out of the path of the brackets or slides of the follower
thereof. This object and effect is obtained by the employment of a valve mon
the water service pipe m², conveying pressure water to the rams d, in connection
with other mechanisms of an automatic nature, hereafter described. The valve m
is so arranged that when opened, if one or other, or both of the doors e were not
fully open, any water that might be inadvertently turned on to the cylinders d,
would escape by the waste escape pipe m² of this valve, and not past the cylinders;
but that when this valve is closed, the waste escape is closed, and all water
admitted to the pipe m' and the valve, will pass to the finishing ram. The auto-
matic mechanism connected with the controlling of the valve m is as follows: -
The valve m is normally closed by a lever n, weighted by a weight n', acting
upon the spindle m³, and it is allowed to open by the lever n being pressed up
by a rod o, which is operated and controlled by two sliding bars p, each of which
is worked to and fro in a guide p¹, from one of the two main doors c, through a
lever on a shaft q' mounted in brackets ², another lever on the upper end
of the shaft ', and a connecting rod r¹ connecting r with one of the bars, at
each side. The rod o has a roller o on its lower end, and the two sliding bars P
-which together are equal in width to the roller o-have each a recess 72 in
their upper edges, at their outer ends, respectively; one bar being operated from
a door c and mechanism at one side, and the other, by the other door and mechan-
ism at the other side. Under any other condition than that in which the doors c
are fully open, the roller o will be riding on a part of the upper edge of one or
both of the slide bars p; and in consequence the rod o will be up and the valve m
open that is to say, in any other condition except that wherein the recesses of
both the bars are directly under roller o (in which condition the roller and rod
move down into them), the lever will be up, and the valve m open; but when

page_text: valve m.
this condition exists, then the weight n is free to press, and presses the rod o and
roller o¹, and valve spindle m³, down and closes the escape opening from the
These relative positions will only take place when the doors chave
both been fully opened, in which action, that is the action of opening, these
doors will have pressed back with them the levers q, and so the rods p, to their
outer limit of stroke (ie. to the position when the recesses are under the
roller o, by the intervening mechanism. The return movement of the rods g
by the doors c is effected by a bar c¹ on the back of the door c, and a pin or
roller at 3 on the end of q, which works in a slot under c¹. Of course the back
of the door, or a rib thereon, acting upon the end of the lever 1, will press the
lever back when being opened.
In the modified mechanism or means shewn in Figures 9. and 10, by which
the control of the press actions, as regards the descent or operation of the finishing
rams d, is effected, the valve which controls the supply of pressure water to the
rams, or their operation, is governed by a brake mechanism controlled by the
position and action of the doors c. In this case, s is the valve controlling the sup-
ply of pressure water to the cylinders of the rams d, and s¹ the operating wheel
on its valve spindles, This spindle s is prolonged, and on the upper end of it,
there is a brake wheel t fixed, the spindle being supported at this end by a
bracket on the ram head f. In connection with this brake wheel t, there are
brake shoes or blocks u, one of which is operated from one door c, and the other
from the other. Each of these blocks is connected with its respective door by a
mechanism consisting of a rod u¹, bell crank lever v mounted in a bracket ¹, and
connected with the shorter end of this lever, a bell crank lever w mounted on one
of the columns h, and connected with by a rod 2 with a weight 3 upon it, and
a tappet or projection on the doors c. In action, so long as one or both of the
tappets of the doors c, are out of contact and not pressing upon the bell crank
levers w, neither of the brake shoes will be pressed onto the brake wheel by
the weight or weights 3, through the intervening mechanism; and the valve
operating wheel and spindle, s¹ s2, will be braked and cannot be moved.
when both of the doors c have been fully opened, as shewn in Figure 10, then
the levers w will both be pressed back by the tappets, and through the mechan-
ism described, both the brake blocks u will be withdrawn from the surface of
the wheel t, and this wheel and the valve unlocked or freed, so that it can be
operated, and pressure water admitted to the finishing ram cylinders.
But
As soon as the rams d have compressed the bale, the valve s and the doors being
open, with the brake blocks clear of the brake wheel t, the men proceed to lash
the bale; and while this is being done, the valve s is shut by the handle s¹. The
outlet valve of the press is then opened, and the rams d leave the bale, which is
then tumbled out.
The main doors c are now to be shut, and this shutting action releases the bell
crank levers w, and the brake blocks u press against the brake wheel and lock
the valve in its closed position, until both the doors c are again fully open.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, we declare that what
we claim is;-
