gate is quadrant type and comprises a wall casting, gate body and
gate shutter. The iron wall casting is belled at its inflow
to approximate the contraction of the jet of the stream. To
the wall casting is attached the gate body, and this is provided
with trunnions at its side. The gate shutter swings on these
trunnions through radial hinge arms. The gate shutter and
body companion surfaces are bronze. These surfaces are made
exactly concentric permitting minimum clearance between these parts
and insuring minimum water leakage.
unit comprises float, float guides and travel limits. The
float is a one piece iron casting with a small cover plate to which
a transmission chain is attached. Float guides are stainless
steel and wall mounted. Travel limits are rotatable fingers
mounted on the transmission shaft.
unit comprises shaft, chain wheels and chain, counterweights, pillow
blocks, roller bearings, and the beams and wall brackets to support
this assembly. The transmission shaft extends from the gate
compartment to the float compartment. The chain
wheels are mounted on the shaft ends and carry the chains to the
float and to the gate. Each chain is provided with a means
of adjustment. One of the chains is arranged to carry sectional
counterweights to assist in placing the equipment in proper balance.
The transmission shaft is carried in moisture-proof roller bearings.
given to the design and the use of quality components provides a
rugged, accurate control that will provide maximum service with
minimum maintenance costs. The experience of over fifty years
of service is being combined with modern materials and manufacturing
methods to produce the reliability demanded by the sewage environment.
