Cutting fluid delivery controller for a sawmill, and methods and systems for controlling delivery of cutting fluid in a sawmill

A cutting fluid delivery controller for controlling a flow of a cutting fluid from a cutting fluid reservoir to a saw blade in a sawmill, said sawmill being of the type having a motor for driving the saw blade, said motor comprising a throttle lever for regulating an operating speed of the motor, the throttle lever being movable between an idle speed position and a cutting speed position, said controller comprising:

• a fluid valve having an inlet for receiving said cutting fluid, an outlet for discharging said cutting fluid for application to said saw blade, a fluid flow path between said inlet and said outlet, and a valve actuator having a first position which causes said fluid valve to block said fluid flow path, and a second position which causes said fluid valve to unblock said fluid flow path;
• a frame member for holding said fluid valve, said frame member having an attachment member for attaching said frame member to said sawmill;
• and
• an operator manipulable actuator for moving the throttle lever between said idle speed position and said cutting speed position;
• wherein when said cutting fluid delivery controller is operably attached to said sawmill, said valve actuator is directly, or indirectly moved from said first position to said second position by said throttle lever, when said throttle lever is moved to said cutting speed position, causing said fluid valve to allow said cutting fluid to flow from said inlet to said outlet toward said saw blade, and said valve actuator is moved back to said first position when said throttle lever is moved away from said cutting speed position, causing said fluid valve to prevent said cutting fluid from flowing from said inlet to said outlet toward said saw blade;
• and
• wherein said operator manipulable actuator is connected to said throttle lever by a throttle link, such that when an operator engages said operator manipulable actuator, said throttle link draws said throttle lever toward said valve actuator.
