ABSTRACT:
A device for feeding workstock to a saw blade. The device includes a friction drive adapted to engage a surface of the workstock to propel the same. The drive is mounted for a range of movement in a direction to accommodate workstock with varying dimensions. A gas spring holds the drive in any selected position within the range of movement and resiliently biases the same against movement away from that position. The gas spring includes a valve system which is operable at least to reduce the bias to facilitate selected adjustment of the drive and closable to hold the drive in a substantially fixed orientation throughout the range of movement.
