Chainsaw Mount Device
20170165827 · 2017-06-15 ·

A counterbalanced chainsaw mount is provided that includes a pin joint, a suspended counterweight, and a counterweight support assembly between the pin joint and counterweight. The chainsaw mount assists cutting a work piece with a chainsaw, controlling the cutting motion and counterbalancing the chainsaw to prevent kickback. The pin joint is secured to a work table or alternative support, whereby the support assembly secures at one end to the guide bar of the chain saw. Along an opposite end, the support assembly supports the counterweight. The support assembly comprises an intermediate member extending along the chainsaw guide bar and an upstanding member supporting the counterweight. The counterweight is positioned an offset distance away from the distal end of the chainsaw guide bar such that the intermediate member is biased to rotate about the pin joint and therefore elevate the proximal end of the chainsaw guide bar while attached thereto.

A control system automates operations of a chainsaw mill. The chainsaw mill has at least one powerhead, and at least one travel motor that mechanically engages with a drive belt to drive the at least one powerhead along a guide track. A tension sensor measures tension on the drive belt, and a powerhead sensor produces a revolutions per minute (RPM) measurement of the at least one powerhead. A powerhead controller is responsive to the RPM measurement for controlling the powerhead's throttle to keep the RPM near a predetermined RPM setpoint. A travel motor controller is responsive to the tension measurement for controlling the at least one powerhead's transit speed along the guide track to maintain drive-belt tension near a predetermined tension setpoint.
