Abstract: For feeding logs to a sawing machine, two parallel horizontal I-beams, at a level above the sawing machine, guidingly support an inner and an outer feed carriage. From each carriage pincers-like log supporting jaws extend obliquely downwardly and in the feed direction. The I-beams provide an inner track that has its rails between the rails of an outer track. The inner carriage is wholly between the rails of the inner track and rides thereon. The outer carriage bridges over both tracks and rides on the outer one, and its jaw operating mechanism has portions above the level of the inner track and other portions extending down from said level that are laterally outside the outer track. The carriages can therefore pass one another and exchange leading/trailing relationship for each successive log. Mechanism is disclosed for causing carriage jaws to close on a positioned log without shifting it but by which the closed jaws can be laterally shifted as desired.
