ABSTRACT:
A cam-lock water gate designed to control water flow from a pond, lake, field, canal or the like. A primary body member is provided with an aperture therethrough and a short section of pipe stub integral with the main body member and opening into said aperture. An adjustable gate plate is mounted on said main body member and constrained between parallel guide channels to permit the gate to be adjusted for completely opening the aperture, partially opening the aperture, or completely closing the aperture. A regular duty embodiment employs a simple handle and rod control for both adjusting the gate plate as well as locking the cam-lock mechanism to positively retain the gate plate in the set position once adjusted. Another heavy duty embodiment employs heavier materials and heavier construction of the device and also incorporates a security lock bar that enables the gate plate to be locked to prevent unauthorized adjustment thereof. Another embodiment employs a threaded rod with adjusting nut operated by a wheel type control. A modified cam-lock mechanism is also incorporated for locking the gate plate in adjusted position. Rustproof and corrosion resistant materials are used for construction throughout all of the embodiments. Because of the lightweight construction employed all of the devices may be installed without the use of heavy equipment for most installations.
