PROVISIONAL SPECIFICATION.
Improvements in Frames for Chaff Cutters and other Machines.
SAMUEL BRASSINGTON BAMFORD of the firm of Henry Bamford & Sons
Agricultural Engineers, Uttoxeter, Staffordshire, do hereby declare the nature of
this invention to be as follows:-
My invention consists of a new method of making the framework or stands for
chaff cutters or other machines when lightness and rigidity are required.
The legs of the framework I roll in wrought iron or steel of angular shape and
the cross stays flat but all the rolled bars have a fillet or raised rib on each
edge as seen from the outside when the framework is put together.
I usually connect the ends of the flat or cross stays to the legs with cast or
wrought plates of suitable design. The plates are shaped to fit the ends of the
stays and also the sides of the legs. The whole can be then rivetted or bolted
together in a rigid and substantial manner.
I sometimes dispense with the use of the plates and rivet or bolt the ends of
the stays on the angular legs.

Improvements in Frames for Chaff Cutters and other Machines.
I, SAMUEL BRASSINGTON BAMFORD, of the firm of Henry Bamford & Sons,
Agricultural Engineers, Uttoxeter, in the County of Stafford, 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 :-
My invention relates to a new construction of stand or framing for a chaff-
cutter or other machines in which lightness and rigidity are required.
According to my invention I make the legs of the framework of wrought iron
or steel of angular section with ribs or fillets on the outside edges and I brace the
legs together by means of cross stays of a rectangular section and also having ribs
or fillets on the outside edges. The stays may be connected to the legs by means
of suitable plates or brackets or they may be connected directly to the legs.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which-
Figure 1 is a perspective view of my improved construction of stand or framing
for a chaff-cutter; and,
Figure 2 is a section drawn to an enlarged scale on the line 2-2 Figure 1:
Figure 3 shews the section of the angular bars forming the legs; and,
Figure 4 the section of the cross stays or braces :
Figures 5 and 6 are a face and edge view respectively of the plate or bracket
which I sometimes employ for connecting the stays to the legs.
a is the bed or table of the chaff-cutter, and b, b are the legs, which legs are as
herein before stated made of angle iron or steel of the shape shewn in Figure 3
and having ribs or fillets c, c on the outside edges. As represented in the drawing
these legs are bolted at their upper ends to the bed a and have bolted to their
lower ends feet d, d.
e, e are the cross stays which are metal bars having ribs or fillets c, c at their
edges, as shewn in Figure 4, and f,fare the brackets which are used in connecting
the said cross stays or braces to the legs. The construction of these brackets will

page_text: be understood by reference to Figures 2, 5 and 6, which shew one of the brackets
drawn to a larger scale than in Figure 1. Each of these brackets has on its front
face a rabbet or recess to fit the angle iron leg as shewn in Figure 2 and on the
back two grooves g, g to receive the ribs c, c of the stays e, the said stays being
bolted or rivetted to the brackets at and the brackets to the legs at i, i.
As hereinbefore stated the brackets f, fmay be dispensed with, the stays or
braces being bolted to the legs.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A framing or stand for a chaff-cutter or other machine, the legs of which are
formed of angle iron or steel of the form shewn in Figure 3 of the drawing with
ribs or fillets upon the edges, the said legs being braced or tied together by ribbed
stays of the section shewn in Figure 4, and the said stays being connected to the
legs with or without the intervention of plates or brackets such as f, substantially
as herein before described.
2. The manufacture and use of frames or stands for chaff-cutters and other
machines, substantially as herein before described and illustrated in the accompanying
drawing.
