Patented Dec. 10, 1935 UNETED STATES rANT orgies MOVABLE WEIR Application June so, 1932, seria1N0.`62o,240 In Germany March 24, 1932 3 Claims. (Cl. 61-28) The present invention relates to an improvement in and relating to the movable weir with triangular cross section according to my previous application ile No. 592,103, and has the object of applying the idea of the original invention to weirs in which the principal weir supports or supporting members are situated at the upstream side of the damming wall. Such a construction may be required when, for any given reason, the arranging of the supporting construction of the Weir body is not possible on the side of the lower water level. This also occurs, for instance, on the lower weir bodies of subdivided weirs, in which the upper body extends towards the downstream side and the lower body towards the upstream side or vice versa. According to the present invention triangular weir bodies having their supporting members at the upstream side of the damming wall are used either for single Weir bodies or for divided weirs having an upper and a lower body which are movable to each other. In the latter case a body having its supporting members at the upstream side of the damming wall may be combined with a body having its supporting members at the downstream side of the damming wall.
In the said weir bodies the supporting members are connected at their one end with the damming kwall and at their other end with one another and are inclined relative tol one another and to the damming wall so as to form a triangle. At the connection of the supporting members with the damming wall two separate girders are arranged while at the connection of the supporting members with one another a single and common girder is arranged. 'I'he said separate girders act as tension girders when they and the supporting members are arranged at the upstream side of the damming wall while the common girder acts as a compression girder when it and the supporting members are arranged at the upstream side of the damming wall and vice versa when the girders are arranged at the downstream side. This construction makes the advantageous damming characteristic of the triangular cross section available also for the damming members which are in the surface water. Besides this, the advantages of this Weir cross section fro-m a hydraulic point of View are also utilized, in that theprincipal support which points upstream and the common girder are placed outside the zone where the current is swiftest.
Figs. 1 to 3 illustrate the present invention by way of an example. Fig. 1 shows a sluice weir in two parts, in which the lower sluice is on the upper water level, in cross section.
Figs. 2 and 3 show a weir in two sections in which the upper sluice lies on the upper water level, in cross section; Fig. 2 shows the upper sluice partly raised, and Fig. 3 the same in partly lowered position.
In all the illustrations the same parts are given the same numbers and I is the upper principal support or supporting member, 2 the lower principal support and 3 the damming wall of the sliuce gate which is on the upper water level; in Fig. l, 4 and 5 are the two separate girders in the form of chords which are on the damming wall and 6 is the single and common girder in the form of a chord for the two principal supports and which is subjected to pressure stress. In Figs. 2 and 3, 'l and 8 are the upper and lower principal supports and 8 is the 20 damming Wall of the sluice lying towards the lower water level. The girders of the principal supports which are arranged on the damming wall are marked l0 and Il and the common girder in the form of a chord l2. The latter is subject to the pressure stress.
It is obvious that the static and hydrodynamic advantages of the sluice with triangular cross section according to my previous application are also obtained for sluices the common girder of which is subjected to pressure stress.
What I claim and desire to secure by Letters Patent is:-
l. Movable weir comprising in combination an upper and a lower body, the said bodies having a triangular cross section and each consisting substantially of a damming wall, two supporting members connected at their one end with the damming wall and at their other end with one another and inclined to one another and the damming wall, the supporting members of the upper body being arranged at the downstream side of its damming wall while the supporting members of the lower body are arranged at the upstream side of its damming wall, two separate girders at the connection of the damming wall with the said supporting members, and a single girder at the connection of the supporting members with one another, the said upper body being arranged at the downstream side of the said lower body and movable with its damming wall on the damming wall of the lower body.
2. r,Movable Weir comprising in combination an upper and a lower body, the said bodies having a triangular cross section and each consisting substantially of a damming wall, two supporting members connected at their one end with the damming wall and at their other end with one another and inclined to one another and the damming wall, the supporting members of the upper body being arranged at the upstream side of its damming wall Awhile the supporting members of the lower body are arranged at the downstream side of its damming wall, two separate girders at the connection of the damming wall with the said supporting members, and a single girder at the connection of the supporting members with one another, the said upper body being arranged at the upstream side of the said lower body and movable with its damming wall on the damming wall of the lower body.
3. Movable Weir including two bodies operatively connected with one another, one of which lies above the other, each of the said bodies consisting of a damming wall, the damming walls of the bodies facing each other, two supporting members which are inclined to one another and connected at their one end with the damming Wall and at their other end with one another, the supporting members of one of the bodies being arranged on the upstream side of the darnming wall and the supporting members of the other body being arranged on the downstream side of the damming wall, two chords at the connection of the supporting members with the damming wall of 'each body, and a third chord at the connection of the supporting members of 15 another.
