AN IMPROVED NORIA OR BUCKET- MECHANISM FOR RAISING LIQUIDS
Year: 1884

page_text: I, JASPER WETTER, Engineer, of 67, Strand, in the City of Westminster, do
hereby declare the nature of said Invention for AN IMPROVED NORIA OR BUCKET-
MECHANISM FOR RAISING LIQUIDS, to be as follows:-
The improved noria or bucket mechanism chiefly comprises a bucket-chain'
dipping into the liquid to be raised and passing at the top over a specially shaped
wheel adapted to set the chain in motion and to receive the contents of the
buckets.
The said wheel has a number of spiral blades similar to those of a centrifugal
pump, which blades are placed between a pair of star-shaped flanges walls or discs
so as to form compartments adapted to receive liquid at the circumference and to
convey it towards the axle of the wheel, on which is mounted a conical tube
serving as outlet for the liquid.
The buckets are triangular and pivoted between the links of the chain the pitch
of the bucket being equal to the length of the link.
When a full bucket reaches the wheel it rests on the edge of one of the spiral
compartments formed in the wheel, and on the further turning of the wheel, the
bucket loses its equilibrium so as to discharge its contents into the circumferential
opening of the spiral compartment. During the motion of the wheel a bolt or
pivot of the chain comes in contact with a lever mounted on a shaft of another
lever, which then meets an arm of the bucket and causes the latter to turn when it
is in a favourable position for discharging its contents.
After the buckets have been emptied they descend on the other side of the
wheel into the water, and are there prevented from turning too far by a blade
projecting from the bottom of each triangular bucket, which blade offers a certain
resistance in the water. The horizontal bolts, which connect the two parallel
halves of the bucket chain and serve as pivots for the buckets, have their bearings
in the forked or looped ends of the links, and to each of the latter is attached a

page_text: short plate serving as a stop or abutment for the contiguous link so as to prevent
the latter from turning beyond a given angle, when passing through its lowest
position.
The inner corners of the star-shaped circumforence of the wheel are provided
with short flanges projecting perpendicularly to the plane of the wheel and serving
as points of support for the flanges at the forked ends of the chain links, so that
the triangular portions of the star-shaped circumference of the wheel pass through
the openings formed between the two halves of the bucket chain.

page_text: I, JASPER WETTER, Engineer, 67, Strand, Westminster, do hereby declare the
nature of said Invention for "AN IMPROVED NORIA OR BUCKET MECHANISM
FOR RAISING LIQUIDS," 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 norias or bucket mechanism for raising liquids, and is
described by the said J. B. Estublier, as follows:
In the accompanying Drawing, Fig. 1 is a front clevation of a contrifugal noria
with 8 spiral blades.
Fig. 2 a side view showing the length of the buckets.
Fig. 3 is a plan of a system of parachute employed if the liquid is to be raised
from a great depth.
Fig. 4 is a front view, a side view and a plan of a bucket.
Fig. 6 is a front elevation of a modified form of noria.
Fig. 7 shows how the links of the chain are put together.
Fig. 8 is a detail of chain with long bands.
Fig. 9 is a detail of chain with knots, applied for great depths.
The improved system of noria or bucket mechanism (Figs. 1 and 2) comprises a
wheel a with 8 spiral blades b. In the interior of the wheel a there is a conc d
which serves as a light supporting core, and forces the water to escape through the
mouth e.
A small tooth-wheelf with pawl serves to hold the noria in position.
The circumference of the wheel a is provided with recesses
adapted to receive
the collars or ends of the bolts h of the chain with long bands i.
The parachute (Figs. 1, 2 and 3), comprises a wooden frame k, preferably made
of oak, a plate cast in one piece with two fixed breaks m, a plate n, a movable
brake o baving 4 hinge joints, two hinged forks s and two brackets, furthermore a
plate q, two fixed brakes r, and two frame supports.
The two forks 8 rub against
the chain with the parts t, (Figs. 1 and 2) while the ends of the forks & cone in
contact with the spindles or bolts h of the chain i.
The forks 8 are attached to the frame u by connecting rods p (Figs. 1 and 3).
To reduce the friction, these forks are very light. Should the chain break, the
forks & would also be broken, if they were not oscillating.
8
If the chain breaks, the spindles or bolts h of the chain fall between the forks,
follow their circumference and draw along the frame u; at the same time the
supports of the four movable brakes are disengaged from the frame and are placed
in front of the fixed brakes r, so as to hold the chain and arrest its fall.
The buckets (Fig. 4) are provided with small hooks x hinged to the same, and
on arriving at the centrifugal noria, they engage in a notch y.
As the chain passes over the wheel and draws the buckets, the small books of
the latter rest against the notch y, causing the buckets to pivot so as to discharge
the liquid. The wheel continues to turn, the hooks remain engaged at
which
now serves to hold the buckets during their descent.
When the chain leaves the wheel, the hooks are disengaged, and the buckets turn
without any shock. In the interior of each bucket there are three cross-bars z
(Fig. 4) serving to retain the ice-blocks which may be formed in the buckets
during cold weather, while the apparatus is at rest; otherwise, on the apparatus
resuming work, the ice-blocks would fall on the noria which not being adapted to
retain the same, would throw them back into the well or pit and might thus
damage the buckets; by means of the bars z, however, the ice-blocks are retained

page_text: in the buckets and redescend to the botton of the well, where they melt after several
turns of the apparatus.
Fig. 6 represents a noria with centrifugal wheel a provided with 6 spiral
blades b, 6 supports c and a conical core.
The full buckets reaching the wheel a aro placed in front of the spirals b, and
turned towards the mouth of the spiral compartment.
The bolts or rings f of the chain (Fig. 7) come in contact with the lever h which
communicates through its shaft i with the lever j, comes in contact with the arm k
of the buckets and turns the same into the proper position for discharging the
liquid.
The spring serves to weaken the shock of the buckets against the blades b.
The empty buckets descend in the same manner as they ascended when full.
The blade m in entering the water, offers sufficient resistance to prevent the
upsetting of the buckets.
:
When full, the buckets are in a somewhat inclined position and follow the
motion of the chain.
The links n (Fig. 7) are provided with plates o serving as a stop or abutment for
the contiguous link, so as to prevent the latter from turning beyond a given angle,
when passing through its lowest position, thereby giving the chain when passing
the bottom of the well, the same form which it takes on the spiral wheel.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :
1. The spiral wheel, with its modifications.
2. The arrangement_of_the_buckets_and_their_connection with the chain or chains,
The whole substantially as described and illustrated.
Dated this 15th day of July 1884.
