Year: 1884

page_text: I GILBERT LEWIS, of the firm of W. Turner of the Adelphi Street Iron Works
Adelphi St Salford, in the County of Lancaster, Engineer, do hereby declaro the
nature of the said Invention for IMPROVEMENTS IN BALING PRESSES, to bo as
follows:-
=
The said Invention relates to the Presses employed in the baling or packing of
cotton jute hay and other materials or goods. To actuate the follower or part
which is pressed upon the materal being operated upon a combination of double
or jointed levers and of a fixed or oscillating bydraulic cylinder or of more than
one such cylinder is employed. The levers are arranged on the toggle-joint system
whereby the leverage increases as the follower advances, or is pressed down.
The press is provided either with revolving boxes or with a fixed box.
211
In the latter case the ends or end sides of the box are continued to the press
head and are formed by long plates which act as and take the places of the
ordinary columns.

I GILBERT LEWIS of the firm of W. Turner of the Adelphi Street Iron Works
Salford in the County of Lancaster, Engineer do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN BALING PRESSES" and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement and accompanying drawings :-
The said Invention relates to the presses employed in the baling or packing of
cotton, jute, hay and other materials or goods. To actuate the follower or part
which is pressed upon the material being operated upon, a combination of double
or jointed levers and of a fixed or oscillating bydraulic cylinder or of more than
one such cylinder is employed. The levers are arranged on the toggle-joint system
whereby the leverage increases as the follower advances or is pressed down.
The press is provided either with revolving boxes or with a fixed box. In
the latter case the ends or end sides of the box are continued to the press head
i and are formed by long plates which act as and take the place of the ordinary
i
columns.
In order that the invention may be fully and readily understood I have provided
three sheets of drawings to accompany this Specification and will proceed to describe
the Invention with reference to such drawings.
In Sheet 1. of the said drawings Fig: 1 represents a Side Elevation and Fig: 2
a Front Elevation of a cotton baling press formed with a fixed box. In the
said Figs: a is the follower b. c. are the toggle-joint levers and d. is the press head.
The said press head is connected with the strong casing e. which forms the press
bottom as is usual but in place of the columns ordinarily used the connection is
made by means of strong plates f. f. which extend from the press bottom to the
press head and are firmly secured to the parts. These plates f. f also constitute
the two ends of the box. The levers b. c. are acted upon by the piston or ram of a
hydraulic cylinder g. which is provided with trunnions h. which are mounted to
oscillate in the framing. The bydraulic piston rod i. is jointed to the upper lever
or combination of levers b. at a point which is intermediate between the connection
with the press head and with the lower lever c. or is otherwise so situated as
to be nearer to the centre of the joint b¹ than is the centre of the joint c¹. This
construction greatly shortens the bydraulic piston.
Sheet 2 illustrates the construction of a press provided with revolving boxes.
In this example the press head and the press bottom are connected by means of
columns as is usual. The two boxes k. k. are mounted to revolve upon the
column . which is made of great strength as it has to withstand the thrust of the
lever c.
The piston rod of the oscillating hydraulic cylinder g. is connected by
means of links m. with the lever b. the point of connection being situated between
the two jointed ends of the lever as in the previous example. This press differs
from the one first described in that the levers are below the boxes in place of
being above the box so that the follower is thrust upward. The press illustrated
by the drawing upon Sheet 3. is also provided with revolving boxes but it differs
from the example given in Sheet 2. in that a fixed hydraulic cylinder is used and

page_text: also that the connection with the levers b. c. is made at the connecting joint
between the two levers as is usual in toggle-joint lover presses. The hydraulic
piston rod or ram is attached to a cross head which slides in ways n. n. and the
said cross head is connected by means of side links o. o. with the lever b. c. The
press is provided with two boxes k. k. which revolve upon the column p.
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 a cotton baling press the box ends secured to the press head and press
press bottom so as to take the places of the ordinary columns in combination with
the toggle-joint levers and oscillating hydraulic cylinder substantially as set forth
and indicated.
2. In a cotton baling press the combination of the toggle joint levers the
bydraulic cylinder for operating upon the same and the revolving boxes substantially
as set forth and indicated.
