WOOD-WORKING MACHINERY.
In illustrating different machinery
in the Wiscoxss LumBERmAN it is our
endeavor to produce accurate repre-
sentations of first-class machines
only, and refer our patrons to first-
class houses. The machines illustra-
ted in this article may best be secur-
ed through the house of 0. L. Pack-
ard, 103 West Water street, Milwau-
kee. The first representation is of a
surface planer, made in several sizes,
to plane from 18 to 30 inches in width
and from 4 to 8 inches in thickness,
either single or double surface. The
peculiar merits of this machine may
be mentined in the facts that it has
weighted pressure rolls, three knife
soLID sTEEL cYLINDER, with self-oiling
cylinder boxes, and AqusTs TmCKNESS
By PowE. Its speed in planing is
from72,000 to 4,000 feet per hour.
The*,second illustration represents
EVABTs SHINGLE A"D HEADING MACHINE
This is the original Evarts Patent
Shingle Machine with improved taper
works. As now made it is regarded
as the very best One Block Hand-
Feed Shingle Machine in use. It
has a self-tilting table, so the opera-
tor need not use his left hand, save
to move the carriage. Any desired
thickness of shingle can be made,
both butt and top, and the taper or
thickness can be adjusted in one
niinute's time. The saw is adjusted
by means of set screws at top and
bottom boxes. It has an adva~ntage
over other Machines in its adaptation
to the sawing of Tight Barrel Head-
ings Thick at the Sap Edge and
Thin at the Heart.
The working capacity of this ma-
chine is 30,000 to 40,000 shingles per
day from green logs of white pine or
cypress, and in yellow pine 12,000 to
15,000 per day, depending on the
skill of the operator. Variations
from these figures may occur from at-
tendant circumstances, and not due
to the Machine, which has had the
