Standard 3-Block Carriage with 4-inch combined steam and
ratchet set works
A Revolving or Flat Scale always indicates the position of the knees. Dogs hold the logs. An Automatic Offset gives a clearance of the saw when on the gigg, and Steel Trucks and Steel Track necessarily go with such a carriage, composed either of heavy T Rail, or the lighter rolled track, according to the size and weight of the carriage.
For accuracy and speed these carriages have no equal, especially when handled by a Prescott Direct-acting Steam Feed.
PACIFIC COAST SCREW BLOCKS
Both the knees and bases of these blocks are composed of solid open hearth steel castings faced with heavy steel bars, presenting wide surfaces for the knees which are grooved to fit them. The knees are supplied with rolls, spud and extension hook dogs. The screws are 4-inch pitch and triple threaded. The gears are steel and cut in a gear cutter and are actuated in setting by hand levers and quadrant or by power in accordance with the wishes of a purchaser.
The Prescott Company furnishes these blocks in the following sizes, viz.: 72-inch, 84-inch and 96-inch; being the distance the knees recede from the saw line.
And in all other respects the equipment of the carriage is very heavy and fully up to date in every respect.
