ABSTRACT:
A scrag saw mill provided with a pair of dogging carriages each carrying a pair of dogs located at opposite sides of the log to be sawed. The dogs are operated by thrust rods from hydraulic cylinders to force the dogs into clamping positions on opposite sides of the log. Means are provided for causing either of said cylinders to exert a predominant force on the log to jog it into place and to equalize the forces to clamp it in place. The log is driven through the mill by an independently driven dog and the carriages are released from the log before they reach the saws. The carriages are returned to predetermine positions as the log proceeds through the final stages of its sawing process.
