TINE undersigned has purchased the Right of
l. the State Of Missouri, Of o. s. Woodcock's
Improved Mode of Hanging Reciprocating Saws,
Patented Sept. II, 1855, No. 1884.
The nature of the improvement consists IN at
taching the lower end Of the saw directly 10 the
upper end of the pitman--the tug pin of the saw
forming joint, and the pitman working on a suit
able fulcrum below the tug-pIn. A represents the
saw sash in about the middle of the downward
motion or cut of the saw. 1t will be perc eived the
lower end of the saw is thrown little forward
TO the cut of the log. represents the saw in the
act of ascending, about the centre of the upward
stroke. 1t will be seen that the lower end of the
saw stands slightly back from the cut. By that
means the saw dust has ample room for escape
during the upward movement of the saw and the
saw is prevented from being checked or clogged.
and will run lighter, and will bear more feed and
consequently cut more rapidly than saws hung in
the usual way. The above cuts are a traverse
section of sash mill, giving full view OF tie pit
man and hiding the lower end of the stiles. The
pitman is fastened permanently 10 the lower rail
by the stirrup coming down on the pitman and
boted securely. The lower ends of the stiles are
connected by Journal Joint 10 the upper edge Of
the rail in any of the usual ways of forming a
working iolnt) The tug-pin will be few inch
es above the JOINTS at the stiles. The upper stir
rup will be in the usual form. The low er strrup
should have set screws 10 keep the saw in line
The bottom of the saw should vibrate about one

When the saw is in motion it makes all epic yclodial

II commences cutting as soon as the crank passes
the upper centre and increases its cut until il
reaches the quarter centre. or half the cut OF The
saw. from that point the cut becomes lessened as
the crank approaches the lower centre. and leaves
the log before the cut is quite spent. and immedi-
atey recedeS from the cut, leaving ample room
for the saw dust 10 escape into the pit In fact
the motion Of the saw pitches every particle Of
the saw dust out of the cut as the teeth of
the saw becomes detached from the log, precisely
as grain leaves the top of an elevator, or water
from chain pump. Tie lcs will remain more
firm on the carriage, when cutting small logs, and
consequently will bear more feed. Every sawyer
has experienced the difficulty of holding small logs
on the MILL Gas il is tcrmed.) particularly Il the
log Is very long, In Woodcock's Patent, that
disagreeable bouncing motion OF the log. is almost
entirely done away with. In large logs it Is
scarcely necessary TO dog the logs the carriage
at all. 1t is a well known tact to sawyers, tina,
in using the recproeating saw with rake. on the
old plan, that there is great difficulty in making
the dogs hold fast, How often have they seen the
saw lit the end of the log clear oil the carriage
blocks, ald by that mears break valuable saw OF
some other part of the machinery? The advan-
tage in cutting with Woodcock's Patent, is this:
1T III Cut Out III re ana one
fourth more in ANAL timber. or it is as easy to rr
through the cetre of log feet in diameter, as
log feet, in saws hung the old plan. 1t has an
other advantage, viz: all The saw dust passes in
to the pit by the cut Of the saw it leaves the floor
of the mill clean, as is also the top of the log whilst
saving.
. 1t works IN Mulley Saw Mill as well as q
sash; all that is required is 10 have fucrum fol-
the pitman, equivalent TO the Journal joints of the
stiles, or by placing the pitman cross head few
inches belowthe top of the pitman Just far enough
to make the top of the ptman or bottom of The
saw yibrate about one and half inch. The prop
er distance for the fulcrum from the top of the
piman will be found, by drafting the length oil
ptman with the length Of crank, or half the vi
bration of the lower end of the pitman.
! The improvement is durable and economical
not liable to get out OF order. Any Mulley OIL
sash saw mill can be changed at the cost of a few
dollars. The extra amount cut IN two days. saw
ing will pay all expenses of the change.
In Mulley saw mills the saw can be attached t.
the upper end Of the pitlnan irons, regulated by
set screws, or by usingthe usual clamp or pendant
The above improvements are being made at al
the principal machine shops in st. Louis.
Persons wishing to make the change can hav
irons manufactured TO suit the situation of tht
mill in which they are to be used.
