The shafts are large with 20″ water cooled boxes. Steam is applied to operate the top guides and adjust the top shaft when desired. A 24-inch double belt is necessary to drive it.
PACIFIC COAST, 9 FOOT SINGLE AND DOUBLE CUTTING BAND MILL
PACIFIC COAST, 10 FOOT BAND MILL
In every respect these mills are splendid creations and exhibit a vast stride in advance of the earlier mills described herein.
All of these mills are provided with a surrounding base, a powered upper guide, quick opening lower guide (as shown on page [45]), live roller, means for maintaining alignments and adjusting the upper wheel when changing saws, the latter being done either by hand or power as required; and the upper wheel in all of these mills when raised to the maximum point admit of the use of a long saw for sawing occasional large logs, a saw two feet shorter being in use normally for medium sizes of logs which are mostly cut. And these mills in combination with a Prescott carriage constitute an equipment absolutely unrivaled by any other productions in the world.
Rack and pinion head blocks, every piece of which is an open hearth steel casting, are furnished in sizes varying from 36 inches to 72 inches, being the distance the knees recede from the saw line; and these with frames proportionate in dimensions and composed of well seasoned southern pine timber, well ironed and braced, comprise great strength and durability.
For mechanically exact setting, all racks, pinions, taper sets and ratchet wheels are cut from solid blanks in a gear cutter. The knees are operated either by hand lever and quadrant, the familiar way, or by a Prescott Steam Setting Machine, which advances them for 4-inch lumber or any thickness less, varying by 1-64th of an inch to every click of a pawl on the ratchet wheel, and that too with a single rearward and return stroke of the piston, so that great speed and accuracy are the characteristics of this machine; and with it an increase of cut is obtained by reason of the fact that the setter does not get tired, and no sawyer will have to wait for him. And more, with them a mill man can keep a good setter who otherwise might be on the hunt for an easier job.
These carriages are also supplied with Friction, Spring or Steam Receders, which latter can be employed in all cases where Steam Sets are used for which steam is delivered to the moving carriage. The value of steam receders consists in the ability to advance or recede the knees at any time whether the carriage is moving or at rest, and for receding the knees of large blocks sawing short logs only.
