Complete Accepted, 1st Apr., 1887.
We, EDWARD FOSTER SANDON, and DINELY FOWLER TONGE, both of the City
of Lincoln, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the construction of machines for hulling
or shelling maize, that is to say, for removing the corn from the cobs without
damaging or breaking them.
The machine consists of a cylinder or cage of a number of bars, of steel or other
suitable material, which bars are retained at proper intervals by a number of metallic
rings. Within the said cylinder is arranged a beater consisting of a central boss
provided with longitudinal wings or blades, which are wormed or screwed for a certain
distance at the feeding end of the drum or cage, for the purpose of driving the maize
cobs forward into the cylinder, as they are fed. Suitable openings are provided at
the respective ends of the cylinder or cage for the feed of the maize and the
subsequent escape of the cobs, the corn passing through the space between the bars.
In constructing machines as herein before described it is important that the size and
arrangement of the various parts are accurate, and in order that these points may be
clearly understood we will now give the requisite particulars for a machine of a given
size, the necessary variations for applying this invention to machines of larger or
smaller capacity will be readily understood by persons conversant with machines of a
similar nature.
In constructing a machine the cylinder or cage of which is about 5 feet in length
and 1 foot 2 inches inner diameter, the hars should be about g of an inch in diameter
and they should be spaced at a distance of about to inch from one another. The
rings for retaining the bars in position should be about 8 inches apart and the inner
edges thereof should project about half an inch above the inner surfaces of the bars.
The diameter of the beater at the outer edges of the blades should be about 10 inches,
and the said blades are wormed or screwed for about one third of their lengths, in
which distance they make about a quarter twist. The said beater is caused to rotate
at about the rate of 700 to 800 revolutions per minute.
Dated this 2nd day of June 1886.

An Improved Machine for Hulling or Shelling Maize.
We, EDWARD FOSTER SANDON, and DINELY FOWLER TONGE, both of the City of
Lincoln, Engineers, do hereby declare the nature of this invention, being a communi-
cation to us from abroad by Louis Pfaff, of Chivilcoy, in the Argentine Republic,
Engineer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our said invention relates to improvements in the construction of machines for
hulling or shelling maize, that is to say, for removing the corn from the cobs, in a
simple and expeditious manner, without damaging or breaking thein and without
injuring the grain.
"The machine consists of a cylinder or cage of a number of bars, of steel or other
suitable material, which bars are retained at proper intervals by a number of metallic
rings. Within the said cylinder is arranged a beater consisting of a central boss
provided with longitudinal wings or blades, by preference, two, which are wormed or
screwed for a certain distance at the feeding end of the cylinder or cage, for the
purpose of driving the maize cobs forward, as they are fed. Suitable openings are
provided at the respective ends of the cylinder or cage for the feed of the maize and
the subsequent escape of the cobs, the corn passing through the spaces between the
bars. The ends of the cage or cylinder are either opened or closed. When desired,
the closing of the same may be readily effected by discs, or, the sides of the frame
may be arranged to effect the desired object. The nature of the invention will be
more clearly understood from the following description of the accompanying drawings
in which the same letters indicate like parts in all the Figures. Figure 1. is an
elevation of the cylinder or cage. Figures 2. and 3. are sectional views of the
respective ends of the same through the lines ... and y. y. Figure 1. Figures 4.
and 5. are elevations of the beater in two positions, one at right angles to the other.
a. are the bars which together with the rings b. and stay bolts a constitute the
cylinder or cage, c. is the opening at one end thereof for the feed, and c¹ is the
opening at the opposite end for the delivery of the cobs. d. is the boss of the beater,
and d d are the wings or blades thereon hereinbefore referred to. The said wings
or blades are wormed or screwed at that end which is situated near the feed hole of
the cylinder or cage.
In constructing machines as hereinbefore described it is important that the size
and arrangement of the various parts are accurate, and in order that these points may
be clearly understood we will now give the requisite particulars for a machine of a
given size, the necessary variations for applying this invention to machines of larger
or smaller capacity will be readily understood by persons. conversant with machines
of a similar nature.
In constructing a machine the cylinder or cage of which is about 5 feet in length
and 1 foot 2 inches inner diameter, the bars should be about of an inch in diameter
and they should be spaced at a distance of about to inch from one another. The

page_text: rings for retaining the bars in position should be about 8 inches apart and the inner
edges thereof should project about half an inch above the inner surfaces of the bars.
The diameter of the beater at the outer edges of the blades should be about 10 inches,
and the said blades are wormed or screwed for about one third of their lengths, in
which distance they make about a quartor twist. The said beater is caused to rotate
at about the rate of 700 to 800 revolutions per minute.
It will be readily understood that machines constructed as herein before described
are suitable for employment in connection with appliances for husking or removing
the outer covering of leaves from the maize cobs, for dressing, cleaning and sacking
the finished corn and elevating and sacking the shelled cobs, they can also be combined
with ordinary thrashing machines.
We are aware that machines for hulling or shelling maize consisting principally of
a winged heater working within a cylindrical cage have been known before the date
of this application, but they have never been constructed in such a manner as to
work successfully.
We are also aware that Louis Pfaff the communicant of the invention is a man of
very large experience in machines of a similar nature and that he is thoroughly
acquainted with what is required of such machines, and we are informed that as the
result of a number of experiments and aided by his experience and knowledge the
said Louis Pfaff discovered that machines of the nature constituting the subject of
this invention to operate successfully must have all parts of the proportional
dimensions herein before stated and such parts must be arranged in the manner
hereinbefore described.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
In machines for hulling or shelling maize, the combination of the cylinder or cage
and the beater, the whole of the parts thereof being constructed of the sizes and
arranged in the manner substantially herein before described.
