PROVISIONAL SPECIFICATION.
Improvements in Presses for Baling Hay, Straw, and other Materials.
We, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford,
Engineer, and GEOFFREY HOWARD of Britannia Works Bedford aforesaid
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to baling presses of the kind described in the Specifications
of Letters Patent No. 5207 of 1879 and No. 1104 of 1881 in which a piston or
ram is moved to and fro in a compressing chamber having an opening through
which the materials to be baled are fed the said piston or ram then compressing
the same.
In carrying out our invention we construct the main frame and the compressing
chamber, by preference, of iron or steel. The top and bottom beams of the frame
are formed of bars of angle or ribbed metal, shaped or cranked in one part of their
length in such a manner that the rear part of the frame is expanded so that the
lower beams rest on the axle of the travelling wheels or on a foundation or the like
and the rear parts of the upper beams are at the proper height to form seatings for
the bearings of the driving shaft. By this arrangement the forward part of the
lower beams are at such a height that relatively large fore travelling wheels may
be employed without raising the general height of the press.
The compressing chamber is formed by rivetting or bolting plates to the beams
of the frame. The discharge end of the press is hinged or pivotted to the other
part so as to admit of being folded or turned up when not in use or when travelling.
The stud axles which support the main driving spur wheels are advantageously
cast with suitable flanges for bolting them to the expanded part of the frame and
made hollow so that oil chambers with syphons can be formed therein and
approached from the outside.

COMPLETE SPECIFICATION.
Improvements in Presses for Baling Hay, Straw, and other Materials.
We, EDWARD TENNEY BOUSFIELD, of Bedford, in the County of Bedford,
Engineer, and GEOFFREY HOWARD, of Britannia Works, Bedford aforesaid,
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 :---
This invention relates to baling presses of the kind described in the Specifica-
tions of Letters Patent No. 5207 of 1879 and No. 1104 of 1881 in which a piston
or ram is moved to and fro in a compressing chamber having an opening through
which the materials to be baled are fed the said piston or ram then compressing
the same.
To enable our invention to be fully understood we will describe how it can be
carried into practice by reference to the accompanying drawing, in which,
Figure 1 is a side elevation of a baling press constructed according to our
invention.
Figure 2 is a section on the line x, x of Figure 1.
Figures 3, 4, 5 and 6 are views of details which are fully described hereinafter.
Similar reference letters indicate the same parts throughout the drawings.

page_text: In carrying out our invention we construct the main frame and the compressing
chamber, by preference, of iron or steel. The top and bottom beams of the frame
are formed of bars of ang'e or ribbed metal a, a and b, b and are shaped or cranked
in one part of their length as shewn at c in such a manner that the rear part of
the frame is expanded so that the lower beams b, b rest on the axle d of the rear
travelling wheels e (or they may rest on a foundation or the like) and the rear
parts of the upper beams are at the proper height to form seatings for the
bearings of the driving shaft. By this arrangement the forward part of the
lower beams are (as shewn in Figure 1) at such a height that relatively large
fore travelling wheels can be employed without raising the general height of
the press.
The compressing chamber of the press is formed by rivetting or bolting plates i
to the beams a and b of the frame as clearly shewn in Figure 2.
The discharge end j of the press is hinged or pivotted to the other part so as to
admit of being folded or turned up when not in use or when travelling.
In Figure 1 of the drawing the upper platen k is shewn hinged at 7 and the
lower platen m at n the dotted lines shewing the position into which the platens
can be moved.
Figures 3 and 4 are respectively a side elevation and plan illustrating the con-
struction of one side of the hinge 7 of the platen k.
It will be seen that the flanged sides of the platens coincide with the sides of
the compressing chamber i and form part of the joint Figure 3. The flanged
sides of the platen being of the same thickness as the sides of the compressing
chamber, there is no projection or break in the continuity of the surfaces.
As the platens k and m have to be lifted either by hand or by mechanical means
into the positions shewn by the dotted lines, it is important to reduce their weight
and length as much as possible, and this we sometimes accomplish by corrugating
the platens across their working surfaces, whereby the required retarding friction
on the bale is obtained with platens of less than the usual length.
The stud axles o which support the main driving spur wheels o are illus-
trated in vertical section and elevation respectively by Figures 5 and 6 and are
advantageously cast with suitable flanges p for bolting them to the expanded
part of the frame and they are made hollow at 9 so that oil chambers with
syphons can be formed therein and approached from the outside by simply opening
the lid r.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. Constructing the main frame and the frame of the compressing chambers of
baling presses of shaped or cranked, angled or ribbed iron, substantially in the
manner and for the purposes hereinbefore described and illustrated in Figures 1 and 2
of the accompanying drawing.
2. Hinging or pivotting the discharge ends of baling presses of the kind described
in the manner and for the purposes hereinbefore described and illustrated in
Figures 1, 3 and 4 of the accompanying drawing.
3. Forming the stud axles of the main driving wheels of baling presses hollow
and with flanges as and for the purposes described and illustrated in Figures 5 and 6
of the accompanying drawing.
4. The manufacture and use of the improved baling press hereinbefore described
and illustrated in the several figures of the accompanying drawing.
