UNITED STATES AUGUST LllUFE-R, OF VIENNA, AUSTRIA.
WHIRLPOOL FILLING AND PARRYING- PLANT.
Application filed December 1921. Serial No. 521,492.
To all whom it may concern:
Be it known that I, AUGUST LAUFER, a citizen of Austria, and residing at Vienna, Austria, have invented certain new and useful Improvements in Whirlpool Filling and Parrying Plants, of which the following is a specification.
This invention relates to a whirlpool filling and parrying plant designed to prevent damages caused by the whirlpool behind a construction such as a weir, in the water.
According to the present invention a suction channel is provided, which terminates in front of a protecting plate, in order to utilize the power of the water falling over the weir for sucking off the water below the protecting plate for preventing any considerable drifting of broken stones or ballast in the whirlpool towards the weir and a consequent excavation of the bottom of the stream or tailraice just below the dam.
A few modes of carrying out the present invention are shown, by way of example, in the accompanying drawing in which Figs. 1 and 2 illustrate in longitudinal section and plan view respectively a plant attached to a fixed weir.
Fig. 3 shows a modified construction of a weir with the end of the suction channel terminating in the rarefied space.
Fig. 4 illustrates the attachment of the plant to a sluice weir. v
The plant comprises a protecting apron or plate to deflect the falling water stream from the bottom of the whirlpool and transforin it into a harmless wavy stream.
The root of the protecting plate a is not fitted directly to the weir, but begins some distance away from the steep back portion of the brickwork of the weir, so that the space thus formed between the said back portion and the root of the plate may act as a suction channel for sucking in the water into the whirlpool e or the upper mouth of the suction channel may terminate in the rarefied space f below the falling stream.
The characteristic feature of the plant according to the present invention consists in that the elfect of suction of the falling stream is utilized to produce a current along the under side of the plate a and at the bottom ofthe whirlpool e which is directed towards the weir d, the said current causing a considerable drift of broken stones or ballast towards the weir and suck the broken stones or ballast, which pass over the protecting plate, into the whirlpool. By this action the power of the falling stream will be diminished and consequently its damaging properties reduced. In order to adapt the deflection and transformation of the falling stream to local conditions and at the same time to facilitate the sucking effect, the protection plate a may be of straight or curved formation and movable or immovable. This plate is spaced away slightly from the base of the weir, leaving a narrow space I). The necessary inclination of the protecting plate with respect to the falling stream may be adjusted by raising or loweringthe same by means of suitable arrangements, or the said plate may be raised or lowered automatically by means of the floating moment of the protecting plate. in any desired material, for instance in concrete, iron or wood constructions and so forth.
I claim:
1. In combination, a weir, and a protecting plate having one edge hingedly connected to the down stream side of the weir to revolve on a horizontalaxis, said hinge connection being fixedly positioned below the crest and above the base of the weir,
said plate being connected directly to the hinge connection.
2. The combination with a weir and side channel walls; of a protecting plate having its upstream edge hinged to the weir above the channel bottom, said plate filling the space between the side channel walls the hinge of the plate being arranged to hold the hinged edge close to the weir and immovable with respect thereto.
3. A whirlpool filling and parrying plant comprising in combination, a weir and a curved protecting plate hinged adjacent the rear face of said weir, said plate having its hinge connection fixed in spaced relation to the down stream end of the weir to provide a suction channel between the plate and weir, said plate having its hinged edge immovable with respect to the weir.
In testimony whereof I affix my signature in presence of two witnesses.
ING. AUGUST LAUFER.
Witnesses:
Ing. 0. Gem, GUILLERMO BECKER.
