I, HUGH JORWERTH ROBERTS, M.I. Mech. E., of Messrs. Burn & Company,
Engineers, Howrah, residing at No. 33, Telkul Ghat Road, Howrah, in the
Presidency of Bengal, British India, do hereby declare the nature of this invention
to be as follows:-
My invention consists in an improved press for baling jute, cotton, hay, grass
or any other materials and which can also be used for extracting oil from seeds
or for other pressing purposes.
Its object is to press any bulky material into bales of a convenient size by hand
steam or other power by a direct motion from a winch using the leverage gained
by long levers and toggle arms of such a form and arrangement that when the
pressing has been accomplished the follower will quickly fall back to its original
position by its own weight.
To attain this object I employ two long levers the upper ends of which are
attached to the follower fixed to the bottom of the press, the lower ends having
pulley wheels. At about the middle of these levers are attached toggle arms
whose other ends are pivotted on a seat fixed on the bed of my machine. On this
seat is fulcrummed a lever (weighted at one end) the ends of which are attached
A chain or rope is
to rods connecting it with the bottom of the long levers.
attached at one end to the seat and passing around both the pulley wheels at
foot of the long levers has the other end attached to the drum of a winch or the
like. On this chain being wound in on the drum the ends of the long levers
(which are guided by means of rollers placed on their lower ends on the bed of
my machine) are drawn together evenly, causing the upper end to rise pushing
up the follower into the box of the baling press. On the chain being released
the follower subsides into its original position by its own weight.

I, HUGH JORWERTH ROBERTS, M.I. Mech. E., of Messrs. Burn & Company,
Engineers, Howrah, residing at No. 33, Telkul Ghat Road, Howrah, in the
Presidency of Bengal, British India, do hereby declare the nature of this invention

page_text: 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 of an improved press for baling jute, cotton, hay, grass
or any other material and which can also be used for extracting oil from seeds
or for other pressing purposes.
Its object is to press any bulky material into bales of a convenient size by hand,
steam or other power by a direct motion from a winch using the leverage gained
by long levers and toggle arms of such a form and arrangement that when the
pressing has been accomplished the follower will quickly fall back to its original
position by its own weight.
I attain this object by the devices illustrated in the accompanying drawings in
which similar letters of reference designate like parts throughout and in which;
Figure 1 shows a side elevation of the press and
Figure 2 a cross section of same.
―
Referring to such drawings N is the head piece composed of rolled beams
supported on columus. M is the jute box which can be run in and out of the
press on trolly wheels and lines. A is the follower. BB are two long side
levers attached to the bottom of the follower at one end, to the toggle armis CC
at or near the centre and at the other end being fitted with guide rollers E E
and chain or rope wheels FF. These arms can be made in one or more pieces
as may be most convenient and of any material. The guide rollers EE run over
the top of the bed J but without touching it and only come into play when the
follower has a tendency to cant on one side or the other, the whole strain being
taken by the toggle arms C, C. RR are guide pulleys for supporting the chain
or rope.
D is the seat attached to bed J on which the toggle arms CC work and
to which also the rocking levers G are fulcrumed. H, H, are connecting rods
attached at one end to the spindles of the long levers B B and at the other end
to the rocking lever G. P is a chain or rope which passes over the chain or
rope wheels FF from one lever to the other, one end being attached to the seat D
and the other to the barrel of an ordinary hand or steam winch. J is the bed of
iron and projects beyond the columns at both ends. To this bed are attached
the columns supporting the heads as also the seat D and guide pulleys R as
described. The top of this bed is straight and is used as a guide for the rollers E E
to run on.
The rocking lever G may be weighted at the end which rises when the bale
is being pressed to assist the follower to descend.
The modus operandi is as follows; -
The box M having been filled with jute, cotton or other material to be pressed
is run into the press into the position shewn in the drawings. The chain or
rope P is then wound in by an ordinary winch which draws in the lower ends
of the long levers towards the centre of the press, the guide pulleys E E, running
over the top of the bed J, keeping the levers steady. The drawing in of the lower
ends of the long levers BB causes them to rise into a vertical position and being
fixed to the bottom of the follower A, force up same into the box M, compressing
the material therein, the pressure being taken by the upper ends of the long
levers BB and the toggle arms C,C. The levers H, H, attached to the rocking
lever G at one end and at the other to the pin at the lower end of the levers B B
prevent one lever B being drawn nearer to the centre of the press than the other
and causes both levers to move inwards at the same time and to the same extent,
any extra strain on one lever being communicated to the other through the
rocking lever G and connected rods H, H. After the bale has been lashed in the
usual manner the chain or rope P attached to the barrel of the winch is allowed to
run out by the brake when the follower subsides by its own weight and the
parts resume the position shewn in the drawings and is ready for another bale.
I do not confine myself to the particular arrangement I have described and illus-
trated but claim to vary same without departing from the essence of my invention.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In presses the use of long levers attached to the follower at one end to a
toggle arm at or near the centre and having rope or chain wheels and guide
wheels attached to the other end substantially as described and illustrated.
2. In presses the use of guide pulleys attached to the end of a long lever as
described and illustrated.
3. In presses the use of a long bed arranged to form a guide for the ends
of the long levers.
4. In presses the use of a rocking lever or disc with connecting rods as
described and illustrated for the purposes aforesaid.
5. The arrangement and combination of the various parts substantially as
described and illustrated for the purposes aforesaid.
