PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Crushing Seeds and Kernels.
We, JAMES DOWNS and JOHN CAMPBELL THOMPSON, both of The Old Foundry,
Hull, in the County of the same, Engineers, do hereby declare the nature of this
invention to be as follows :—
Seeds, such as linseed and the like, have been frequently crushed by passing them
through between a succession of rolls which are conveniently arranged in a framing,
one above another, and all adjusted simultaneously by setting screws. In this
arrangement of apparatus the rolls are very close together so that they do not readily
admit between them kernels such as those of palm or cotton.
In order that these bodies, which are larger than seeds, may be fed to the upper
pair or pairs of rolls, we place between the bearings of these rolls blocking pieces
adjustable by set screws with lock nuts, so that the upper pair or pairs of rolls,
while their bearings are subject to the same pressure as those of the lower rolls, are
kept sufficiently far apart to admit the kernels between them. We also helically flute
these rolls, and make the flutings finer and finer as the rolls are lower, the lowest
pair or pairs being smooth.
The helical flutings being all to one hand, those which present themselves on the lower
side of each roll cross those which present themselves on the upper side, and thus
the seeds or kernels are subjected to a kind of grinding action.
In order still farther to produce this grinding action, we drive the uppermost roll
at a greater surface speed than the next roll in order below it, and in some cases we
employ this differential speeding for several of the tiers of rolls.

Improvements in Apparatus for Crushing Seeds and Kernels.
We, JAMES DOWNS and JOHN CAMPBELL THOMPSON, both of The Old Foundry,
Hull, in the County of the same, Engineers, 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:-
Seeds, such as linseed and the like, have been frequently crushed by passing them
through between a succession of rolls, which are conveniently arranged in a framing,
one above another, and all adjusted simultaneously by setting screws. In this
arrangement of apparatus the rolls are very close together so that they do not

The belical flutings being all to one hand, those which present themselves on the

Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In apparatus for crushing seeds and kernels, consisting of a series of rolls
arranged above one another and pressed towards each other, the use of adjustable
blocking pieces between the bearings of the successive rolls, substantially as and for
the purpose set forth.
2. In apparatus such as is above referred to the use of smooth rolls at the bottom
and of rolls above them helically fluted to one hand, with flutes finer the lower the
rolls, substantially as described."
