TIME undersigned has purchased the hlght OF
l. the State of Missouri, of o. S. Woodcock's
Improved Mode of Hanging Reciprocating Saws,
Patented Sept. IL, 1855, No. 1884.
The nature Of the improvement consists IN at
tachinE the lower end OF the saw directly 10 the
upper end of the pitman--thc pin of the saw
forming Joint, and the ptman working on SUIT
able fulcrum below the tug-pin. represents the
saw sash in about the middle OF the downward
motion or cut Of the saw. " will be perceived the
lower end of the saw is thrown a 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 traverse
section Of sash mill, giving full view Of the pit
man and hiding the lower end Of the stiles. The
pitman is fastened permanently TO the lower rail
| by the strrup coming down on the pitman and
bolted securely. The lower ends Of the STILES are
connected by journal Joint TO the upper edge of
/ the rail Gin any of the usual ways OF forming
working iolnt.) The tug-pin will be a few inch
! es above the Joints at the stiles. The upper stir
rup will be in the usual form. The low er stirrup
| should have set screws to keep the saw in line
The bottom of the saw should vibrate about one
and half inch SO to clear the cut without Civ
ing the saw any rake. (The saw being plumb,
when tine crank is on the upper or lower centre
When the saw is in motion it makes an epicyclodial
curve at evei revolution CT the crank. Any prac-
teal sawyer will readily see the advantages of it,
It commences cutting soon as the crank passes
the upper centre and increases lis cut until 1t
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-
ately Tectdes from the cut, leaving ample room
FIR 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. The log 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 log.
on the mill, as it is termed,) particularly if the
log is very long. In WoodCock's Patent, that
dsagreeable bouncing motion of the log, is almost
entirely done away with. in large logs it l:
scarcely necessary to dog the legs on the carriage
: at all. 1t is a well known fact to sawyers, tha
in using the reel proeating saw with rake, on the
e old plan, that there is great difficulty in making
the dogs hold fast, How often have they seen thu
saw lit the end of the log clear of the carrag,
2 blocks. and by that mears break valuable saw o.
= some other part of the machinery? The advan
s tage in cutting with Woodcocli's Patent. is this
il will cut one half more in large timber, and or
fourth in ANAL timber, or il is as east 70 Ri
through the cetre OF Il log feet IN diameter. ds
log feet, in saws hung the old plan. 1t has an
other advantage, Wis as all the saw dust passes in
to the pit BY the cut of the saw, leaves the foo
of the mill Glenn is also the top of the log willis
:, saving.
1t works IN Mullry Saw Mill as well as
q sash; all that is required is TO have fulcrum 70
a the pitman, equivalent to the journal joints of tn
u stiles, or by placing the pitman cross head FEY
4 inches below the top the pitman just far cnoug
y to make the top of the pitman or bottom of tn
saw vibrate about enc and half inch The prop
. err distance for the fulcrum from the top of IN
: ptman will be found, by drafting the length c
II pitman with the length of crank, or half the Vi
:, bration of the lower end OF the pitman,
. The Improvement is durable and economical
II not liable to get ont of order. Amy Mulley c
" sash saw mill can be changed at the cost Of FEY
. 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 pitman irons, regulated b
a set screws, or by uSihgthe usual clamp or pendan
~ The above Improvements are being made at a
the principal machine ships in ST. Louis.
Persons wishing TO make the change can hay
irons manufactured TO suit the situation OF tn
=, mill in which they are TO be used.
