Improvements in or appertaining to Cotton or other Baling Presses..
A communication by JOHN FRANCIS ELSWORTH, of Alexandria, Egypt,
Engineer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham, in
the County of Warwick, and 31, High Holborn, in the County of Middlesex,
Civil Engineer, 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 :-
In the working of baling presses in which one or more boxes are revolved or
slid under a fixed bale chamber, so that their contents are added together to form
one bale, and receive a further or final compression, it is usual to make these
revolving or sliding boxes without a bottom, their contents being retained by a
smooth plate over which they slide.
When working in this manner it is necessary to support the material when forced
into the bale chamber, to prevent its expanding upon the withdrawal of the
compressor; so that other boxes containing the material may be presented to the
bale chamber to have their contents added to that already in. The usual means
adopted for attaining this, are bars, bolts or quadrant plates, projecting into the
interior of the bale chamber and are usually known as "fingers." These fingers
are actuated by mechanism to cause them to recede at the proper time to permit the-
passage of material into the chamber and to project under the material when the
compresser is being withdrawn.
Now according to this invention, each box is provided with the exception of the
last, with a loose bottom formed of a plate which may be called a grid, having
notches cut in its edges corresponding with the fingers of whatever kind, in the
sides or ends of the bale chamber, so that these fingers can in no way interfere with
the passage of the grid plate up or down in the bale chamber.
In the accompanying drawings:-
:-
Figure 1 is a plan and Figure 2 an edge view of a convenient form of grid plate
with notches, A, specially designed for a baling press having retaining devices or
fingers such as described and shown in a former Patent No. 13876 of 1894. The
said notches A are arranged to coincide with the fingers in the side or end of the
bale chamber, so that these fingers can in no way interfere with the passage of
the loose bottom or grid up or down in the bale chamber. The working of the
baling press remains substantially the same as before, but by the present invention,
the weight of the material in the boxes is sustained by these loose grids, thus
avoiding the friction caused by their sliding over the plate hitherto provided. The
upper surfaces of the grids may, if desired, be grooved for lashing the bales as
shown at B in the edge view, Figure 3, which grooves need not coincide with the
notches A so that the bale may be lashed whichever box is in the press. The
object of making this provision is that the same box or boxes may be passed any
number of times under the bale chamber to have their contents collected. It must
be distinctly understood that this invention is not confined to the exact form, size
or thickness of loose bottom shown on the drawing, as this may vary to suit
the particular form of fingers used, the main idea being to provide a bottom
for the boxes which shall pass up and down inside the bale chamber unobstructed.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, 1 declare that what I claim is :-
1. The improvement in or appertaining to presses for baling or compressing
cotton or other material, which consists in providing the baling boxes with a loose
bottom or grid, formed in such manner with notches or their equivalent, that when
the said baling boxes are presented to the bale chamber to have their contents
transferred thereto, for compression, the said grids will be enabled to pass any
fingers or retaining devices that may be provided in the sides or ends of the said
bale chamber for holding the material compressed, substantially as described.
.
2. In apparatus of the kind set forth, the use, in combination with sliding or
revolving baling boxes, of loose bottom plates or grids formed with notches, and
grooves, substantially as set forth, the former adapted to clear any retaining devices
that may be used for holding the material compressed in the bale chamber, whereby
these retaining devices will in no way obstruct the free passage of the grids, and
the latter adapted to facilitate the lashing of the bales.
3. The loose bottom plates or grids constructed and arranged substantially
as described and shown on the accompanying drawings, and for the purposes set
forth..
