Improvements in Enclosed Waterwheels and the like.
I, HENRY SIDEBOTTOM, of 6A, George Street, Manchester, in the County of
Lancaster, Hydraulic Engineer, do hereby declare the nature of this invention
to be as follows:-
My object is to form an enclosed waterwheel which shall give better results
from a high or low pressure volume of water than have hitherto been obtained.
I accomplish this (referring to the drawings sent herewith) by forming the
periphery a of the wheel with two side rims b of suitable height so as to form
with the periphery itself an annular trough or groove within which are placed
dashers or plates c at a right angle to the radii of the wheel, so as to form a
series of cups or pockets d with an aperture or outlet e at the bottom of each.
This wheel runs within a suitable casing f which closes in the top of the annular
trough or groove for about one half of its circumference.

Improvements in Enclosed Waterwheels and the like.
I, HENRY SIDEBOTTOM, of 6A, George Street, Manchester, in the County of
Lancaster, Hydraulic 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: —
My object is to form an enclosed waterwheel which shall give better results
from a high or low pressure volume of water than has hitherto been obtained.
I accomplish this by forming the periphery of the wheel with two side rims
of suitable height so as to form with the periphery itself an annular trough
or groove within which are placed dashers or plates at a right angle to the radii of
the wheel; so as to form a series of cups or pockets with an aperture or outlet
at the bottom of each.
This wheel runs within a suitable casing which closes in the open side of the
annular trough or groove for about one half of its circumference.
In most cases, especially when the supply of water is limited and the pressure
low, the best result is obtained by keeping the casing close fitting to the sides
of the annular trough of the wheel, but in some cases when there is an abundant
FD 077

page_text: supply of water at a high pressure I find it advantageous to allow more room
for the escape of the surplus water from the cups or pockets of the waterwheel.
I wish it to be understood also that I do not confine myself to placing the
dashers or plates at an exact right angle to the radius of the wheel, although I
find this the best in nearly all cases, but may slightly vary the angle in some
cases.
Referring to the drawings sent herewith, Fig. 1 shows a side elevation of one
form of my improved waterwheel, partly in section.
a indicates the periphery of the wheel with two side rims b forming an annular
trough in which dashers or plates e form a series of cups or pockets d having
each an aperture or outlet e at its lower end.
The wheel runs within casing f into which water is admitted by inlet pipe g
and after passing half round the wheel finds it's outlet at h.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
".

1st. The combined apparatus, substantially as described and shown herein before
and in the accompanying drawings, for the purpose set forth.
2nd. In enclosed waterwheels and the like, forming the cups or pockets of the
same with an aperture or outlet at the lower end, substantially as described and
shown hereinbefore and in the accompanying drawing.
