Abstract
Abstract The gate pivot is formed by a rotatably mounted tubular beam on which the frame is mounted by means of bearing members which are provided on the frame and engage peripheral surface portions of the tubular beam spaced apart at a sufficient angle, and which members are locked in such engagement by bolts that are secured to the frame and extend therefrom and into securement with the tubular beam along lines located between radial lines through such surface portions. A tank for the sector float of the gate is supported at one end by the walls of the water course and at its other end by rollers engaging the peripheral surface of the tubular beam.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
286 words
A water gate comprising a frame, means for supporting said frame for pivotal movement about a fixed axis, a sector-shaped gate apron mounted on the upstream end of said frame, and a sector float mounted on said frame and disposed downstream of said pivotal axis and rotatable about the same, said supporting means comprising a beam extending transversely of said frame, and means rotatably supporting said beam, and means detachably securing said frame to said beam including seating means fixed to said frame and seated on one portion of the exterior surface of said beam subjected to a line of force that is predominately of the weight of the frame and seated on another portion of said surface subjected to a line of force that is predominately of the hydraulic thrust on the apron, the force acting on the beam through said seating means due to the weight of the frame acting on a line which extends vertically from the pivotal axis, with the hydraulic thrust force acting therethrough acting on a line passing through the pivotal axis and positioned 90* from the vertical on the upstream side of the beam, first connecting means secured to said beam, and second connecting means including a member detachably connected to said frame and connected to said first connecting means, said first and second connecting means being constructed and arranged to press said seating means on the exterior surface of said beam and maintain the same seated thereon and to exert an anchoring force securing said frame to said beam and acting along a line extending through the pivotal axis of the beam and dividing the angle formed by said two force lines of predominant weight and hydraulic thrust.
Claim 2
Dependent Claim
286 words
A water gate comprising a frame, means for supporting said frame for pivotal movement about a fixed axis, a sector-shaped gate apron mounted on the upstream end of said frame, and a sector float mounted on said frame and disposed downstream of said pivotal axis and rotatable about the same, said supporting means comprising a beam extending transversely of said frame, and means rotatably supporting said beam, and means detachably securing said frame to said beam including seating means fixed to said frame and seated on one portion of the exterior surface of said beam subjected to a line of force that is predominately of the weight of the frame and seated on another portion of said surface subjected to a line of force that is predominately of the hydraulic thrust on the apron, the force acting on the beam through said seating means due to the weight of the frame acting on a line which extends vertically from the pivotal axis, with the hydraulic thrust force acting therethrough acting on a line passing through the pivotal axis and positioned 90* from the vertical on the upstream side of the beam, first connecting means secured to said beam, and second connecting means including a member detachably connected to said frame and connected to said first connecting means, said first and second connecting means being constructed and arranged to press said seating means on the exterior surface of said beam and maintain the same seated thereon and to exert an anchoring force securing said frame to said beam and acting along a line extending through the pivotal axis of the beam and dividing the angle formed by said two force lines of predominant weight and hydraulic thrust.
