Head—block.

1. (Saw-mill.) a. The block on which the head — or forward end — of a log rests in the ordinary saw-mill; the other end is the tail-block, and they are parts of the carriage on which the log is moved to the saw and gigged back.

Head-block for saw-mills.

b. One of the pieces forming the log-bed in a circular or veneer saw mill. (See circular saw.) In the example the sliding knees d form abutments for the log which rests on the head-blocks b, and are [1085] moved by screws in the head-blocks. On the ends of the screws are the wheels a, which are moved simultaneously by the lever e, rod m, and racks s s.

2. (Vehicle.) A piece of wood attached below to the upper ring of the fifth wheel and above to the front spring, also having the front end of the perch mortised through its middle.
