PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing and Stoning Grain.
I, JOSEPH SENIOR, of Bridge Street, Wakefield, in the County of York,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of apparatus for washing and stoning
grain in which two cylinders each having an internal spiral groove are arranged
in oblique position and revolve either intermittently or continuously and through
which cylinders the grain travels with a suitable flow of water during the time
the stone or other heavier ingredient deposits into the said spiral grooves and
travels out at one end of each cylinder while the grain travels out at the other.
These cylinders have hitherto been made of copper with the internal spiral groove
in the form of a channel brazed thereto and have consequently been both
expensive of material and elaborate of construction the object therefore of my
present invention is to construct said cylinders of a cheaper and more suitable
material and also to simplify their construction which I attain by forming each
cylinder in one solid piece of earthenware having the internal spiral groove
formed therein and made in one with said cylinder or where found convenient
each said cylinder could be made of glass or other similar substance with the
internal spiral groove formed in the said substance and each cylinder could be in
two or more sections cemented together or where preferred each cylinder may
have an iron or other metal casing lined with earthenware glass or other similar
material in which lining the spiral groove may be forined as will be well
understood. By the use of my present invention the manufacture of each cylinder
is not only considerably cheapened but the usual expansion and contraction
experienced in cylinders of ordinary construction is obviated and each cylinder
is free from corrosion.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Washing and Stoning Grain.
I, JOSEPH SENIOR, of Bridge Street, Wakefield, in the County of York,
Manufacturer, 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:-
This invention relates to that class of apparatus for washing and stoning grain
in which two or more cylinders each having an internal spiral groove are
arranged in oblique position, and revolve either intermittently, oscillatory, or
continuously, and through which cylinders the grain travels with a suitable flow
of water during the time the stones or other heavier ingredients deposit into the
said internal spiral groove or grooves, and travel out at one end of each cylinder,
during the time the grain may be travelling out at the opposite end of each said
cylinder. These cylinders have bitherto been made generally of copper or metallic
substance with the internal spiral groove in the form of a channel brazed thereto,
and they have in consequence been both expensive in material, and manufacture,
and complicated in construction, the object therefore of my present invention is to
construct cylinders used for the purpose specified of a cheaper and more suitable

page_text: material, and also to simplify their construction and manufacture; to attain which
I employ cylinders and manufacture the same in manner set forth in the
accompanying sheet of drawings in which
Fig. 1 is a longitudinal sectional elevation taken on line aa of Fig. 2, which
latter is an end elevation of a washing and stoning machine constructed with my
improved cylinders.
Fig. 3 is a back view of ordinary gearing which I preferably employ for driving
said cylinders so as to obtain an oscillatory rotating motion.
Fig. 4 is a side elevation partly in section of an apparatus I employ in the
manufacture of my improved cylinders, and Fig. 5 is a sectional plan taken on
line of same,
Fig. 6 is an elevation of my improved cylinder when finished ready for being
fitted to the remaining part of the stoning and washing machine.
Similar letters of reference denote corresponding parts in each view.
Each cylinder C is formed of earthenware and preferably in one piece, having
the internal spiral groove c¹ formed therein, and made in one with said cylinder.
I find it convenient to manufacture each earthenware cylinder C in the following
manner: I press by the aid of an ordinary sanitary pipe making machine, a plain
cylinder with its external diameter of size to suit required size of cylinder C, and
its internal diameter of size to suit internal diameter of thread or spiral groove c¹.
I allow this clay cylinder to become well dried, when I subsequently place it in the
apparatus shown at Figs. 4 and 5 which has a vertical stand D on which is mounted
a spindle E having a spiral thread e¹ corresponding to pitch of screw thread c¹ in
cylinder C, and working in the head d. To the top of spindle E is fixed a hand
wheel G, and at the lower end is fixed an adjustable cutter H having its cutting
edge made to form to suit required shape of the threaded groove c', which I prefer
to make straight at the rising side of thread, and tapered at the descending side as
shown. To the stand D is mounted a hinged cylindrical case F, within which I
place as aforesaid the dried clay cylinder C, I then turn the hand wheel G when
the spindle E causes the cutter H to cut away the clay, so forming the thread c¹ as
represented at Figs. 1 and 6. A small oblong opening is cut through the cylinder C
at, and the thread e¹ finishes up to the same, and the internal part of the upper
end of cylinder C is cut away preferably by the rectangular cutter fl shown
attached to the spindle E. The internal part of the lower end of cylinder C is
also cut away and has three lugs et formed in it as shown at Fig. 5. The improved
cylinder C is then burnt and salt glazed in a similar manner to a salt glazed sanitary
pipe, it is then ready to be fitted to the apparatus. One end of said cylinder C fits
into the box ; which bears on the divided feed pipe K, the latter being fixed to the
stand 1, the other end is fitted to a box or flange m, the boss of which is fixed to
and carried upon a shaft p to which is fitted the toothed wheel q. Each toothed
wheel q is driven by a cam wheel mounted upon a shaft s, to which is fitted a fast
and loose pulley. The divided branch pipe K has a feed branch k¹ and a water
branch, which latter communicates with the receiver T. The grain is fed in
at and the water at 2. As the cylinders revolve and oscillate the stone or heavy
ingredients deposit into the threaded groove c', and are carried upward and fall out
of the hole c², and out of the hopper e, and at the same time the grain is carried by
the flow of water down the cylinder C, and is delivered at the lower end into the
hopper w. It will be obvious that any suitable kind of clay can be used for the
manufacture of my improved cylinder, and where preferred the cylinder may be
encased with iron or other metal. Although I show an apparatus for forming the
thread in the cylinder C, I would have it understood that the said thread could
be formed by a metallic core.
I do not lay claim to the combined apparatus as illustrated, as the machine as a
whole is well known and I only illustrate and describe the machine in order that it
may be fully understood as to what kind of apparatus my present invention is
applicable, therefore

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. The use in apparatus for washing and stoning grain, of an earthenware
cylinder C, constructed and arranged substantially as described and illustrated.
