Improvements in Water and like Wheels.
I, HENRY ARTHUR MAURER, of No. 110, West 75th Street, in the City of New
York, County and State of New York, U.S.A.. 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:—
The primary object of the present invention is to provide a water wheel of the
kind described which shall be simple and inexpensive in construction and by
the use of which in connection with a jet or jets of water or other fluid projected
on one side or the other of the wheel, the latter may be revolved with equal
speed and force in either direction. A further object of the invention is to
provide a simple and easily applied means for connecting a wheel rigidly to a
shaft and for disconnecting it therefrom when desired.
With these objects in view the invention consists of a water wheel having con-
nected to the periphery thereof two series of buckets or vanes having cups for
receiving the impact of water under pressure, the cups of the buckets of the
respective series being oppositely arranged so that water projected against the
buckets or vanes of one series will result in turning the wheel in the opposite
direction to that in which it will be turned it projected against the buckets or
vanes of the other series. Further the invention consists of a water wheel having
a double or bifurcated periphery, each portion of the periphery being provided
with a series of buckets or vanes, the openings for the reception of water pro-
jected against the buckets being oppositely arranged in the respective series.
Further the invention consists of a water wheel having a recess in the inner
face of its hub, a shaft having a corresponding recess, a key arranged in the
recesses, whereby the wheel is removably secured on the shaft.
The invention is illustrated in the accompanying drawings, in which :-
Figure 1 is a side view of a water wheel constructed in accordance with my
invention:
Figure is an end view thereof:
Figure is a central vertical sectional view, showing the means for securing
the wheel on the shaft and
Figure 4 is a similar view of a modification.
In Figs. 1, 2 and 3 of these drawings 1 represents the water wheel, the main
portion of which is preferably of one piece of metal.
On the periphery of the wheel are arranged two series of buckets or vanes 2,
having indentations or cups 3 therein for the reception of the impact of water
from suitable nozzles by which the water, under pressure, is directed against the
buckets or vanes.
The buckets or vanes are preferably constructed as shown, each being divided
with a central rib or projection 4. against which the water is discharbed and by
which the streams of water are divided and directed into the cups.
The outer
edges of the cups are somewhat lower than the rib or projection 4, so that water
projected into the cups will be discharged from the outer edges thereof free from
the buckets, in order to offer no obstruction by contact with them, to the free
revolution of the wheel.

page_text: In order that there may be a space on each side of each series of buckets or
vanes 2, the periphery of the wheel is bifurcated as shown in Figures 3 & 4
of the drawing, forming two circumferential ribs 5, 5, to which the two series
of buckets or vanes are respectively attached. This connection allows the free
and unobstructed discharge of water from the inner as well as the outer faces of
the buckets, and thus the water used to propel the wheel, while under pressure,
will not come in contact with any part of the wheel except the buckets and any
impinging of the water while under pressure against any part of the wheel which
might result in retarding the revolution of the latter is obviated.
The preferred means for attaching the water wheel 1 to its shaft 6, is clearly
shown in the sectional view, Figure 3. The hub 7 of the wheel is cast on the
wheel and is chambered as shown at S. and that portion of the shaft 6 which
comes opposite a chamber is provided with a corresponding indentation 9.
Arranged in the spaces thus formed when the wheel is in place on the shaft are
keys 10, adapted to lie partially in the chamber in the hub and partially in the
indentation in the shaft. Each of the chambers in the hub is of a size capable
of entirely receiving its key, to allow the latter to be placed in the chamber
when the wheel is slipped on and off the shaft. The key is moved to and retained
in proper position in the spare formed for its reception to connect the wheel to
the shaft by the screws 11. 11. These screws extend through screw-threaded
openings in the hub and bear at their inner ends against the edge of the key. A
serew 12 passes through an unthreaded opening in the hub 7 and into a threaded
hole in each of the keys 10, and is employed for the purpose of withdrawing the
key from its indentation in the shaft back into its chamber in the hub.
In arranging the wheel on the shaft the key is placed in the chamber in the
hub and the shaft is introduced through an opening in the hub. The chamber in
the hub and the indentation in the shaft are brought opposite each other, and
then the screws II are moved in. forcing the key to a position partially in each.
the hub and the shaft. By tightening the screws the key will be firmly
seated and as a result the wheel is rigidly secured to the shaft. When the
screws 11 have been loosened and the serew 12 is turned, the key is drawn
back into the hub, allowing the removal of the wheel.
In Figure 4 is shown a modified arrangement for removably securing the
wheel to its shaft. In this figure the hub 13 is formed in two halves and separate
from the wheel 1S. This wheel has the bifurcations and the two series of
buckets 2 shown in the other figures of the drawings and already described. The
two halves of the hub 13 are secured to the wheel and on each side thereof by the
bolts 14. The hub is provided with one or more chambers which come opposite
corresponding indentations in the shaft, and keys 15 fit in the chambers of the
hub and in the corresponding indentations of the shaft. The outer edges of these
keys also fit into notches formed in the body of the wheel. In mounting the
wheel on its shaft the keys 15 are first put into their proper indentations in the
shaft, the wheel is then slipped into place over the keys, the keys fitting into
the notches of the wheel. The two halves of the hub are then brought up
against the sides of the wheel, the chambers of the hub fitting over the keys.
The bolts 14 are then fastened through the two portions of the hub and the wheel
body, as shown in this figure, thus locking the wheel securely in its place on the
hub.
Water or other fluid under pressure from a pump or pumps or other suitable
source is projected from nozzles 16 or 17 upon one or the other of the series of
buckets or vanes 2 according to the direction in which the wheel is to be revolved.
The nozzles, of which any desired number may he employed, are arranged
at suitable angles to cause the water to be directed by each to the buckets at angles
which will most effectively drive the wheel, and each nozzle is so located as to
strike the rib or projection of each bucket of the series against which is directed.
The buckets or vanes employed are all of the same size, so that the water
from both sets of nozzles being under the same pressure and delivered in the

page_text: same quantity from each, the wheel may be revolved in either direction with equal
power and speed. This feature of my invention has especial advantages in the
uses to which the wheel may be be placed, particularly when it is employed on a
vessel when quick reversal of the direction of movement and rapid attainment of
full speed in either direction is essential.
Having now particularly described and ascertained the nature of my said
invention, and in what matter the same is to be performed, I declare that what
I claim is:-
1. A water wheel having on its periphery two or more series of buckets or
vanes oppositely arranged, substantially as described.
2. A water wheel having on its periphery two series of buckets or vanes
oppositely arranged, there being a space on each side of each bucket allowing
the free discharge of water therefrom, substantially as described.
3. A water wheel having its periphery formed by two ribs, each rib being
provided with a series of buckets, the buckets of the respective series being
oppositely arranged, substantially as described.
4. A water wheel having a bifurcated periphery, each portion being provided
with a series of buckets or vanes, substantially as described.
5. A water wheel having its hub provided with one or more chambers, a
shaft having indentations corresponding to the chambers in the hub, a key
arranged in each chamber and indentation, and screws for adjusting the key and
retaining it in position, substantially as described.
6. A water wheel having a hub formed separate therefrom and in two halves,
bolts for fastening the two parts of the hub to the wheel on each side thereof,
