Improvements in Pulping and Slicing Machines.
We, LYMAN MELVIN JONES, Manufacturer, WILLIAM F. JOHNSTON, Manufac
turer, and WILLIAM JOHN CLOKEY, Pattern Maker, all of 915 King Street, West,
in the City of Toronto, in the County of York, in the Province of Ontario, Canada,
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 :-
Our invention relates to improvements in pulping and slicing machines and the
object of the invention is to provide an improved form of pulping and slicing-
machine in which there will be no possibility of the roots choking on their passage
to the knives and in which such roots may be very finely and rapidly cut or pulped as
required and readily discharged from the machine and it consists essentially of a
pulping and slicing machine having a wheel with the pulping or slicing knives.
extending through slots in its periphery, the rim being broad V-shaped in cross
section and an enlarged concavo-convex throat being provided the lower edge of
which extends preferably beneath the centre of the wheel and in proximity to it
and is in cross section reversely shaped to the rim of the wheel so that the lower
edge fits closely to the broad V-shaped rim, the bottom of the throat being
stiffened and the machine being otherwise constructed as hereinafter more particu-
larly explained.
Fig. 1, is a perspective view showing the side of the machine broken away to
exhibit the construction of the wheel and throat.
Fig. 2, is a longitudinal vertical section through the machine.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A, is the hopper at the bottom of which is suitably journalled in bearings, A¹, the
shaft, B, upon which is secured the pulping wheel, C. The end of the shaft, B,
has secured to it a hand or fly wheel, D.
or
The rim of the pulping wheel, C, is broad V-shaped in cross section and has a
central web, C. Each side, C2, of the broad V-shaped rim is provided with
slots, C³, C3, which extend from edge to edge of the rim. There are a series of
the slots, C³, C³, around the rim and each is provided with a reversible pulping
slicing knife, E, the pulping edge being in this instance_shown as extending
obliquely through the rim. The pulping and slicing knives, E, are secured under-
neath the rim to raised projections, E, by suitable bolts, e. G, is the chute upon
which the roots are feed to the wheel, C, of the machine. H, is a concavo convex
throat formed at the opposite end of the machine to that at which the roots are
fed in, being in cross section broad V-shaped reversed, so that the lower edge, h,
comes in proximity with the broad V-shaped surface of the rim. The lower edge, h,
is also preferably situated beneath the centre of the shaft and is stiffened by a
bolt, I. The bolt, I, extends through a lip, h¹, formed below the bottom edge of
the throat, H, and extending obliquely away from the rim of the wheel, and passes
through a cross bar, J, extending between the legs of the frame. The outside of
the throat is provided with flanges, H', which are provided with a number of bolt
holes through which extend bolts, h².
To place the throat in position the bolts are passed through the holes in the
flanges, which fit the bolts loosely and the bolt, I, is passed through the lower lip, h¹,.
and cross bar, J. The lower edge h, is then adjusted to the proper relative position.

page_text: to the rim and the nuts, i, i, on the bolt, I, are then jammed up to each side of the
cross bar; the bolts 2, then may have their nuts screwed home upon them, so as
to securely hold the upper portion of the throat firm.
The throat constructed as above described serves to prevent the choking of the
roots as they pass down towards the wheel as the broadest portion of the throat is
opposite the top of the wheel and consequently the roots will more readily drop from
the narrow portion into the broad portion. We are also enabled to have two sets
of pulping or slicing knives operating upon the roots at the same time and as such
lower edge of the throat is below the centre of the shaft of the wheel it will be
seen that the knives operate upon the roots at a point where they act with the
most advantage.
In order to provide a means for ejecting the roots after they have passed into the
interior of the wheel we provide a scraper, K, at each end which is bolted at the
top to each bearing bracket, A, and has an inwardly and obliquely shaped blade
formed on its end extending inwardly substantially parallel to each side of the
broad V-shaped rim but of sufficient distance away from the rim to clear the
knives. In the drawing one bearing bracket and scraper only is shown the side of
the machine being broken away but it will of course be understood that at the
opposite side of the machine a scraper similarly formed and located is provided.
On account of the shape of the rim of the wheel with the outer edges of greater
diameter than the centre it will also be seen that the roots will more readily be
ejected from the machine.
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. In a pulping and slicing machine the combination with the wheel having the
rim broad V-shaped in cross section extending across and suitably journalled at the
bottom part of the hopper and provided with slots extending across the rim and
knives extending obliquely through the slots and bolted underneath the rim, of
the concavo-convex throat reverse broad-V-shaped in cross section and having
the lower edge extending below the centre of the wheel and located in proximity
to the rim as and for the purpose specified.
2. In a pulping and slicing machine the combination with the wheel having the
rim broad-V-shaped in cross section extending across and suitably journalled at the
bottom part of the hopper and provided with slots extending across the rim and
knives extending obliquely through the slots and bolted underneath the rim, of the
concavo-convex throat, H, formed as specified and having its lower edge located in
proximity to the wheel, the lip extending downwardly from the lower edge, a bolt
extending through such lip and a cross bar of the machine and provided with
suitable jam-nuts, flanges H¹, formed at the outside of the throat and bolts, h³,
extending through holes in such flanges as and for the purpose specified.
3. In a pulping and slicing machine the combination with the wheel having the
rim broad-V-shaped in cross section extending across and suitably journalled at the
bottom part of the hopper and provided with slots extending across the rim and knives
extending obliquely through the slots and bolted underneath the rim, of scrapers
having the blade extending obliquely into the interior of the wheel from each side
as and for the purpose specified.
