PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting or Slicing Roots.
1, WILLIAM BLOOMFIELD BRETT, of Mundesley Road, North Walsham,
Norfolk, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to that class of machines for cutting or slicing roots known
as" Gardner's 30 Knife Machine." In these machines, each knife has hitherto been
made in a separate piece; the knives have been bolted to wrought-iron plates, and
the plates riveted to the barrel. In practice it is found that spaces are worn
between the knives and plates, which spaces fill with rubbish and interfere with the
clean and efficient operation of the machine.
The object of my invention is to remedy this defect, and this I accomplish by
making the knives and plates in the same piece of metal, instead of separately.
The barrel of the machine is made in two sections; the cutters and plates are made
in four sections, each of these four sections being cut and shaped from one piece of
steel, and attached to the barrel in any suitable way.
་
The machine could be made to cut different sized pieces, by varying the space
between the cutters, or the number of notches in each section.

1, WILLIAM BLOOMFIELD BRETT, of Mundesley Road, North Walsham,
Norfolk, 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 :-
The object of my invention is to simplify the construction of root-cutting
machines such as that known as "Gardiner's Turnip Cutter," which have hitherto
been made with each knife separate and forming a distinct piece; each knife being
attached to a cast-iron barrel with one bolt, wrought iron plates are then fitted up
to the same and secured with rivets.
I will now describe the invention with reference to the accompanying drawings in
which
Fig. 1 shows a side elevation in section of the machine with end view of barrel
mounted on the usual frame and fed with roots from the top through the usual
hopper.
Fig. 2 represents a plan of the interior, part of the barrel being covered by the lip
of the hopper.
Fig. 3 shows a side elevation of one of the curved plates or sections *, out
of which the cutters a, are formed. One of these plates is shewn in position on the

page_text: shell, of the barrel, the cutters a, being held in position on the shell through their
lower or bent ends, by the wedges or rivets h.
Fig. 4 shows a plan of the curved plate or section .r, and also shows the shell f, of
the barrel in position, the wedges h, being shewn in dotted lines.
Fig. 5 shows the front or end plate of hopper which holds the roots, with holes k,
to receive the base of each of the pointed cutters b.
Fig. 6 is an end elevation of part of the barrel c.
Fig. 7 is a plan of same with holes or slits to receive the bent ends of the
cutters a.
Fig. 8 shows in detail enlarged views of the wedges h and ¹.
The
Fig. 9 shows a plan view of one of the sections a, before being curved and
exhibits the stepped angular ends which form the cutters a, when bent over.
dotted lines y, show where the bending of the cutter occurs.
Fig. 10 shows a perspective view of the curved plate or section r, when curved
to fit the barrel, and also shows the cutters a, bent ready for fastening to the barrel
and for cutting the roots.
a, a, are the knives formed out of curved sections a, Figs. 9 and 10.
b, b, are cutting points for cutting the last piece of the root.
c, c, are the two halves of the barrel bolted together around the spindle d, by the
bolts . d, is the square spindle. e is the outlet for the cut material. f, Figs. 3, 4
and 7 is the curved plate forming part of the shell of the barrel into which the
cutters a, are fastened. x, is the curved plates or sections.
9, 9, are holes in the knives for insertion of wedges h.
, is the wedge for fastening the knives in position.
are wedges for keeping the pointed cutters & in position.
k, k, are the holes in the hopper to receive the cutters b.
1, 1, are bolts which connect the two parts of the barrel.
m, m, are slits in the plate f, to receive the knives a, a.
The first part of my invention applies to the barrel which is made in two parts
and bolted together at the boss as shewn, preferably on a square spindle. This
barrel is shewn in Fig. 1.
In the outer shell, of the said barrel are formed slits m, m, to admit the lower
ends of cutters a, as shewn in Figs. 3 and 7.
These knives extend step-fashion as shewn, across from one part of barrel to the
other, and the curved section out of which they are formed or fastened and held
securely with bolts n, Fig. 1 to the barrel shell f.
The second part of my invention relates to the cutters a, of which there are four
sets, each set being formed out of a steel section x. (Figs. 9 and 10) and curved to
fit the shell of the barrel f. The cutters a, when bent over are held by means of
wedges, in the slots m, which are formed to receive them. The said angular ends
are shouldered to stand out the required distance on the rim of the barrel, holes g
Fig. 3 being punched in their lower ends and secured with wood or metal wedges,
as shown by dotted lines in Fig. 4, and the ends of which are shewn at h, in
Figure 3.
My combined plate and knife could also be adapted to the ordinary pattern
barrels.
The third part of my invention relates to apparatus for cutting the last piece,
which is attained by forming in the front or end part of the hopper, a series of slots
or oblong shaped holes k, Fig. 5 in which are inserted steel points or knives b,
Figs. 1 and 2 and which are secured with wood or metal wedges, projecting through
the plate about half an inch and opposite the angular part of the cutters.
The last pieces that do not pass through the barrel are cut by the projecting
kuives or points and fall into the shoot as shown in Fig. 5.
The Specification and drawings refer to a thirty-knife machine, but other sizes
such as a fourteen aud ten-knife machine could be made on the same principle by
varying the number of notches on the angular ends.

page_text: 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.) In a root-cutting machine the special construction of barrel as herein
described and set forth.
2.) In a root-cutting machine the special construction and arrangement of
combined plates and cutters as herein described and set forth.
3.) In a root-cutting machine the method and arrangement of parts for cutting
the last piece, in combination with the special construction of barrel and combined
plates and cutters, as herein described and set forth.
Dated this 11th day of December 1894.
