Hydrostatic weir shutters usually require, owing` to the considerable lateral eX- tension of the flaps as compared with the vertical adjiistability of the shutter7 a very wide and costly substructure.
The object of the present invention is to produce a hydrostatic weir shutter wherein the lateral extension o't Jthe iiaps but little exceeds the vertical adjiistability of the shutter7 and the invention consi.V in the provision of two hingedly connected shutter plates supported like a root structure on two horizontally hinged 'flaps turned in opposite directions and located in hydrostatic chambers.
The accompanying drawing repipeeiits a Cross-section of the weii' and shows the shutter in fully extended position.
The substructure 8 is ioriiied 'with two hydrostatic chambers 7 and 7 which can each be connected through channels 9 and 9 respectively and by means of the usual controlling` devices, either with the high or with the low water. Pivoted horizontally at G and G to the substructure boia-seen the two chambers, are two flaps; 5 and frL which are preferably sector-shaped and buoyant and which are oscillated by iluctiiations in the water pressure. Two shutter plates 1 and 1, which are pivoted together at 3, are
- pivoted at 1 and 4e respectiveiy to tl e :tree
Cil
ends ot' `the ilaps 5 and 5 so as to form a roof-shaped structure which determines the level of the water head in the upper pooh munication with the lower pool, the flaps 5 will be lowered into the position shown by the dotted lines 5b, and the shutter plates will take up the position shown by the dotted lines 1" and 1.
still further To lower the shutters 'the communication of the chamber 7 is also changed trein the upper to the lower pool so as to allow the ilap 5 to drop into the position shown at 5, the shutter plates being then lowered to the positions 11 and le.
For raising the shutter,
the chambers are again set in communication with the upper pool either one at a time or simultaneously.
1n this arrangement the shutter plates 1, 1n are comparatively Short and the chainbere 7 and 7 very shallow.
The width ot l el aim 1. i hydrostatic weir shutter Comprising a substructure having two hydrostatic chambers arranged in juxtaposition, flaps arranged iii said chambers and adapted to swing in vertical planes ated at the adjacent sides of the chambers, and shutter plates hinged together and to the free ends of the iiaps so as to 'forni a roof-shaped structure which can be raised and collapsed by means of the flaps.
2. A structure as claimed in claim 1 wherein the iaps are sector-shaped and buoyant.
3. The structure claimed in claim 1 in combination with means for setting either chamber independently in communication either with the lower pool.
or with the upper FRANTISEK Juni/IAR.
