Lloyd Larson's 'Jackson Lumber Harvester' is shown
in the picture sawing lumber at the Lake Region Pioneer
Thresherman's Association Show at Dalton, Minnesota, on
September 18-20, 1959. The sawmill is powered by Johnson's
22H.P. Special Avery Under mounted Steamer, formerly owned and
rebuilt by Clinton D. Jackson, inventor and founder of the
world-famous 'Jackson Lumber Harvester'. Although the
'Lumber Harvester' is seemingly a small mill, it took all
the horse power any of these steam giants could 'dish out'
in stride, without the sign of a rattle or groan of any kind. It
converted this rip-tide of power into thousands of feet of
accurately cut lumber to the astonishment of many old-timer sawmill
men.
The unique feature of these Jackson mills is that the sawyer
rides the carriage and goes back and forth with the log as the
boards drop off in clock-like precision, maintaining quality,
accuracy and production in proportion to the power available ....
all this in a trailer sawmill! (One old timer remarked,
'It's jeweled like a watch and runs like a new sewing
machine.')
It has not only precision bearings on the mandrel, as many
up-to-date mills do, but a total of 74 ball and roller bearings.
The main frame is fabricated by the electric arc process into a
single homogeneous mass while it is being held in a steel jig
embedded in concrete. It is so held until entirely cooled. This,
together with the many precision bearings and the strategic design
used by Jackson, is the key to its remarkable success.
Some of the shows in 1959 at which this remarkable mill proved
its amazing performance were:
