Improvements in Kibbling Mills for Splitting Beans, Peas, and
the like.
I, JAMES GADSBY RICHMOND, of the Firm of Richmond and Chandler, of
Globe Works, Southall Street, Strangeways, Manchester, in the County of
Lancaster, Agricultural Engineers, do hereby declare the nature of this invention
and in what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to the construction of kibbling mills for splitting beans,
peas, indian corn, oats and other grain, and the object of my invention is to prevent
the kibbling roller or box of the machine from being broken when any hard foreign
substance is fed into the machine, and this I effect by making a special kibbling
plate or a part in connection therewith so constructed and designed that it will
break under any undue shock or pressure before serious injury is caused to
the kibbling roller or box of the machine.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying five sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a sectional side view of sufficient of a kibbling mill to illustrate my
invention.
Fig. 2 is a transverse section on the line A B, Fig. 1.
Figs. 3 and 4 and Figs. 5 and 6 are similar views to Figs. 1 and 2 respectively
illustrating slightly modified shapes of kibbling plates, of which a variety could be
made according to my invention.
Figs. 7 and 9 are similar views to Fig. 1 and Figs. 8 and 10 are front views
of two alternative arrangements, according to my invention, in each of which a
special easily breakable part is employed in connection with the kibbling plate.
Referring first to Figs. 1 to 6 of the drawings,-(a) designates part of the
roller box, (b) the kibbling roller, (c) the kibbling plate provided with a nib or
projection (el) and fitted upon a stud (d) carried in the ends of the roller box (a),
and (e) an adjustable stud or bolt against which the nib or projection (c¹) rests;
all the other parts of the mill are made in the usual or any convenient manner.
When the mill is in operation the beans or grain are kibbled or split between the
roller (b) and kibbling plate (e) as usual. The kibbling plate (c) according to my
invention is made of cast iron or some other brittle metal so proportioned that the
plate is the weakest part of the mill and consequently should any hard foreign
substance enter the machine of too large a size to pass between the roller and plate
the latter will be broken across the junction between the nib or projection. (c¹) and
the kibbling plate.
The parts are grooved or otherwise shaped to allow the nib or projection (e¹) to
be broken off and thus allow the main portion of the plate (c) to move back and
release the hard substance whereby both it and the piece (c¹) can fall out of the
machine without causing serious injury to the roller (b).
A new kibbling plate can be readily placed upon the stud (d) to make the mill
again ready for its work.
I wish it to be clearly understood that I do not bind myself to make the nib or
projection (e) the weakest part or breaking point of the kibbling plate although I
have shown and described it so for the purpose of conveniently illustrating the
nature and object of my invention.
Referring now to the alternative arrangements illustrated by Figs. 7 to 10.
In Figs. 7 and 8 the kibbling plate (c) has no nib or projection (el) but bears
against a stud (e) fitted to slide through a hole in the box (a); the end of this

page_text: stud (e) abuts against one of the nibs or wings of a star wheel (which is threaded
on a screw (g) which screws into the frame (a). The star wheel (f) is kept from
turning by means of a pivoted catch (h) and its nibs or wings are partly cut through
or otherwise prepared so as to readily break off when subjected to any undue strain
although strong enough to resist any ordinary pressure.
In Figs. 9 and 10 the stud (e) is fitted to slide in a sleeve (i) which screws into
the frame (a) and has fixed upon it a star wheel (j). The kibbling plate (c) bears
against one end of the stud (e) the other end of which abuts against one of the
nibs or wings of a small star wheel (f) which is fixed adjustably to the larger star
wheel (1) by means of a screw (y).
In operation when any hard foreign substance is introduced and forces back the
kibbling plate (c) and sliding stud (e) the latter breaks off a nib from the star
wheel (f) and allows such substance to pass without doing any serious damage to
the roller (b).
The kibbling plate (c) can be re-set by simply slackening the screw (9) and
turning the star wheel (f) sufficiently to bring a fresh nib or wing in position
against the end of the stud (e).
Again I wish it to be clearly understood that I do not bind myself to the arrange-
ment of a star wheel with nibs or wings prepared to break as instead of a star
wheel a thin metal or other suitable plate or part could be employed if arranged
as an abutment to receive and resist the ordinary working pressure and to break and
yield when subjected to any undue strain.
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 kibbling mill for splitting beans, peas and the like-
1. A kibbling plate provided with a nib or projection arranged so that the
plate will break and yield before serious injury is done to the roller or frame by
the passage of a hard foreign substance through the mill substantially as herein
described with reference to Figures 1 to 6.
2. The combination with a kibbling plate, of a star wheel with nibs or a thin
metal or other plate or part arranged as an abutment to support the kibbling
plate under normal conditions and to break and yield under undue pressure
substantially as and for the purposes herein described with reference to Figures 7
to 10.
