Improvements in Water Wheels.
I, HENRY JONES, of Colwood, in the County of Victoria, Province of British
Columbia, Canada, Mill-wright, 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:-
1
My invention relates to improvements in water wheels.
The object of my invention is to provide a device of this character in which
the water will be passed to the vanes in such manner as will exert a maximum
amount of power. A further object is to provide a water wheel which will be
durable in construction; which is operated with absolute precision, and which
can be manufactured at a moderate cost.
To these ends my invention consists in the improved construction and com-
bination of parts hereinafter fully described and particularly pointed out in the
claims.
In the drawings, in which similar letters of reference indicate similar parts in
all of the figures:-
Figure 1 is a vertical sectional view of my improved water wheel shown in
position for use,
Figure 2 is a sectional view of one of the nozzles.
Figure 3-is a sectional view showing the arrangement of the vanes.
A designates a cylindrical pen-stock, having the sides a, top a¹ and bottom a².
A suitable opening a communicates with the head-race, the entrance of the water
being regulated by means of a suitable gate a¹. A central tube a5 is secured in
the top and bottom within which the shaft of the wheel proper is located. The
bottom a is provided with openings a arranged near its outer edge, within
which are placed nozzles a', having their peripheries screw-threaded and adapted
to be screwed into collars as mounted in said openings a. When less pressure
is desired, the number of the openings are reduced by removing the nozzle a and
inserting a plug into the collars. If desired, a stop may be formed on the
nozzle, as shown in dotted lines in Figure 2. The pen-stock is secured on suit-
able supports a, by means of supporting flanges a¹0 The pen-stock is also pro-
vided with suitable man-holes a" and suitable air-cocks and pressure gauges, the
latter not being shown, they not forming any particular of my invention, and
may be of any preferred construction.
B designates a base, formed of suitable material, and having a reinforcing
top b, within which is mounted, if desired, a ball bearing race-way b¹ or if pre-
ferred roller bearings may be substituted.
C designates my improved wheel, having its central portion formed of suitable
material, and having on its outer face vanes c formed preferably as shown in the
drawings, although I do not limit myself to this precise construction. These
vanes are adapted to be secured to the outer face of the wheel C and to a supple-
mental ring or rim c¹, and are arranged at an angle to the axis of the wheel,
the position being such that water falling through the nozzles descend on the
central portion of the vanes. As shown, the vanes are preferably formed with a

page_text: pointed upper edge to prevent the water from splashing, etc.
The shaft c, pre-
ferably mounted on a ball pivot, and extending upward through tube a".
D designates a draft tube, adapted to extend below the level of the tail water
and be secured to the pen-stock outside of said wheel.
The operation is obvious, inasmuch as when the water is passed downward
through the nozzles, it drops on to the vanes, causing them to be carried backward
and thus rotate the wheel. The power is regulated by the number of nozzles
remaining open.
By this construction the entire amount of water used exerts its full power to
rotate the wheel, there being no tendency to cause back pressure of any kind.
Suitable oil ducts are provided for the oiling of the various bearings.
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:
-
1. The combination with a pen-stock, having controllable ports; of a wheel,
located below said pen-stock, said wheel being provided with vanes arranged to
receive the impact of the water passed through said ports.
2. The combination with a pen-stock, having controllable ports; of a wheel,
located below said pen-stock, said wheel being provided at its outer edge, with
angularly secured vanes, arranged to receive the impact of the water passed
through said ports.
3. The combination with a pen-stock, having controllable ports; of a wheel,
located below said pen-stock, said wheel being provided with vanes arranged to
receive the impact of the water passed through said ports, and a draft tube adapted
to be secured outside of said vanes.
4. The combination with a pen-stock; of a water wheel arranged thereunder ;
a support for said wheel; and anti-friction devices located between said wheel and
said support.
