PROVISIONAL SPECIFICATION.
Improvements in Certain Machines for Splitting Beans, Peas,
and the like.
I, JAMES GADSBY RICHMOND, of the Firm of Richmond and Chandler, of
Southall Street, Manchester, in the County of Lancaster, Agricultural Implement
Makers, do hereby declare the nature of this invention to be as follows :-
My invention relates particularly to what are known as "Biddell's Bean Splitting
Machines" and the object of my invention is to protect the crushing cylinder or
kibbler barrel from breakage or injury in the event of any hard substance such as
iron or stone entering the space between the crushing cylinder and grinding plate
whilst the machine is in notion.
To effect this object I hinge or pivot a plate or plates in the frame or box of the
machine; the front edge of this plate rests normally along the face of the crushing
cylinder at a suitable distance to allow the beans etc. to be split or crushed to the
required size and at the back of this plate a strong spiral or other suitable spring
or weight and lever arrangement is placed.
So long as the beans to be crushed pass through the machine the plate has little
or no movement; but in case of a piece of metal or stone getting on to the cylinder
and between the cutters and the plate the spring will yield or the weight will lift
sufficiently to allow the same to pass without injury to the cylinder after which the
plate will be at once restored to its working position by the spring or lever.
Means are provided for adjusting the spring or weight and lever and plate
relatively to the crushing cylinder so that the material can be split or kibbled finer
or coarser as may be required.

COMPLETE SPECIFICATION.
Improvements in Certain Machines for Splitting Beans, Peas,
and the like.
I, JAMES GADSBY RICHMOND, of the Firm of Richmond and Chandler, of
Southall Street, Manchester, in the County of Lancaster, Agricultural Implement
Makers, 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 particularly to what are known as "Biddell's Bean Splitting.
Machines" and the object of my invention is to protect the crushing cylinder or
kibbler barrel from breakage or injury in the event of any hard substance such as
iron or stone entering the space between the crushing cylinder and grinding plate
whilst the machine is in motion.
To effect this object I hinge or pivot a plate or plates in the frame of the box
of the machine; the front edge of this plate rests normally along the face of the
crushing cylinder at a suitable distance to allow the beans etc., to be split or crushed
to the required size and at the back of this plate a strong spiral or other spring is
placed.
Means are provided for adjusting the spring and plate relatively to the crushing
cylinder so that the material can be split or kibbled finer or coarser as may be
required

page_text: And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Figures 1, 2 and 3 are sectional elevations of three arrangements according to
my invention.
In Figure 1-a designates the crushing cylinder or kibbling barrel, & the
kibbler box or frame, and c the grinding plate which is pivoted at d to the box b.
To the kibbler box b is secured or cast a box e into which is screwed a bolt fon
which is fixed a hand wheel g so that by turning the wheel g and screwing the
bolt the head of the latter can be adjusted relatively to the cylinder or kibbling
barrel a the bolt f being then locked by the lock-nut h. On the bolt f is fitted
loosely a washer or flanged boss k between which and an adjustably fixed washer i
is a compressed spiral spring the tension of which can be regulated by screwing
the washer i upon the bolt f. The pivoted plate c bears against the loose washer k
and so long as the beans etc. to be crushed pass through the machine the plate c
has little or no movement; but in case of a piece of metal or stone getting on to
the cylinder and between the cutters and the plate, the spring will yield
sufficiently to allow the same to pass without injury to the cylinder a after which
the plate c will be at once restored to its working position by the spring j.
In this arrangement the plate c can be adjusted relatively to the cylinder or
barrel'a by releasing the lock nut and turning the hand wheel g so as to screw the
bolt up or back.
In Figure 2 the grinding plate c bears against a stud / which screws into a flanged
bush m and when adjusted is fixed in position by a pin n. The spiral spring is
compressed between the bush m and a button or flanged stud o which is kept in
position by the screwed bolt f.
The action of the parts is substantially the same as in Figure 1 the spring j
yielding to allow any hard substance to pass the plate c without injury to the
cylinder or barrel a.
In Figure 3 the spring box e is secured to or cast in one piece with the kibbler
box or frame b and in it is fitted a bolt f the shank of which is squared for a short
distance near its head and on this squared portion is fitted loosely a washer k a
projection k¹ on which enters a groove e' in the spring box e to prevent the washer k
from turning round. The spiral spring is compressed between the washer k and
the end of the spring box e and the tension is regulated and the position of the
plate c adjusted by turning the hand wheel g which is then locked in its position' by
means of the pivoted catch

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:
+
In a Biddell's bean splitting machine →
1. The combination with a pivoted grinding plate, of a spring support arranged
to yield and allow any hard foreign substance to pass between the said plate and the
crushing cylinder without injury to the latter.
"
2. The several combinations and arrangements of parts substantially as herein
shown and described, for the purpose specified.
