Improved Wood-working Machine, Combining Circular Saw,
Band Saw, Boring Mill, and Lathe.
I, CHARLES WILLIAM FERGUSON, of 16, Eastburn Place, Langside, Glasgow,
North Britain, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved machine suitable for joiners, carpenters,
wheelwrights and such like; and has for its object a combination of parts, which
consist of circular saw, band saw horizontal boring mill and lathe combined, on
one portable machine.
The frame of this improved machine, consists of a table supported on end-
uprights bound together by longitudinal beams, which support the table longi-
tudinally. Underneath the table about half way from each end, I suspend a
shaft, which may be driven by motive power, by hand or by the foot, by means
of a crank and treadle. Loose on this shaft, I put two double arms, which can
be moved independent of each other, concentric to the shaft; but when in work-
ing position are fixed diametrically opposite. The one carries a spindle to which
a circular saw boring-bar or lathe chuck can be attached; and the other a spindle,
to which the bottom pulley for band saw is attached. On this shaft between
the inner and outer members of the double arms, I fix a pulley-fly-wheel, which
carries two bands gearing on pullies, one of which drives the spindle, on which
a circular saw boring bar or lathe chuck is fitted; and the other the band saw
spindle.
By means of a screw, attached to end of framing and secured by nuts to a
crosshead on double arm carrying circular saw, boring or lathe spindle, I adjust
this spindle relatively to table; and by the same means, I tighten the band saw,
but to give elasticity to the saw, I put spiral springs between the nuts and the
crosshead.
The top pulley for band saw is carried by a bracket atfached to top or side
of framing.
I make the pulley, which drives the circular saw boring or lathe spindle, with
long boss, having a sunk journal, which is carried in a bearing block attached
to end of double arm. The spindle fits inside of this boss and is carried at its
other end by a block, which is also attached to end of arm, and can be moved
laterally: I engage the spindle with pulley by means of a long feather on spindle
fitting into groove in boss of pulley; and by preference I move it laterally by
means of levers & screw: or other suitable method.
I may sometimes attach a lathe bed to this machine, for turning shafts & such
like, and will set it at right angles to framing in line with lathe spindle.

I, CHARLES WILLIAM FERGUSON, of 16, Eastburn Place, Langside,, Glasgow,
North Britain, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to an improved machine suitable for joiners, carpenters
wheel-wrights and such like, and has for its object a combination of parts, which
consists of circular-saw, band-saw, horizontal-boring-mill and lathe combined in
one portable machine.
And in order that my said invention, and the manner of performing the same
may be properly understood, I hereunto append two sheets of explanatory draw-
ings to be hereinafter referred to in describing my improvements.
Figure 1 on Sheet 1, of the accompanying drawings, is a side-elevation of
my improved machine and Figure 2 on Sheet 2, an end-elevation looking from
the band-saw end. The same reference letters are used to denote the same parts
in different views.
In carrying out my invention I provide a table A supported on end uprights B,
which are bound together by the longitudinal beams C which also support
the table A longitudinally, and have bearings 1 to carry the shaft E, which
may be driven by motive power through the pulley F, or by hand by means of
a suitable handle-not shewn--or by the foot by means of a crank H connected
by a link to treadle 2. On shaft E I fix a pulley-fly-wheel I which drives
the pullies O and S by means of bands J and J. Loose on shaft E I place two
double arms K and L which can be moved independent of each other concen-
tric to the shaft E, but when in working position they are fixed diametrically
opposite. The double arm K is fixed and adjusted by a screw and nuts a
and ; and the double arm L by a screw and nuts 12 and 13 having spiral
springs and placed between the nuts and crosshead 76 which connects the two
members of the arm L. My object in placing the springs as shewn is to give
elasticity to the band saw T.
In the bearings and, attached to the arm K, I put a spindle M, which
carries the circular saw N used for cross cutting or ripping purposes; but this
saw can be removed and a boring bar attached to spindle M for boring pur-
poses, or a lathe chuck for turning shafts wheel centres and such like.
I make the pulley which drives the spindle M, with a long boss in which
is formed a sunk journal, which is carried in the bearing attached to end of
arm K. The spindle M fits inside of this boss on pulley O, and it is carried at
its other end in bearing, also attached to end of arm K; and the spindle M
can be moved laterally through these bearings. engage the spindle M with
pully by means of a long feather fitted in spindle and fitting into grove in
boss of pulley 0; and by preference I move the spindle M laterally, when used
for boring & such like purposes by means of a screw P and levers p1 and p2 on
shaft p3, but it may also be wrought by a hand lever and link or other suitable
means.
The adjustable table p carries the subject to be operated upon by the boring
or mortising tools.
For actuating the band-saw T. the spindle R, to which are attached the pulley S
and bottom-band-saw pulley . is carried in the bearings 18 and 77 on arm L:
and the top-band-saw pulley 1 revolves on a stud 3 carried by the bracket t.

page_text: The band-saw-table 5 is attached to an arm 6, which forms a ball and socket
joint at t with beam C by this means the table can be set to any angle required,
and fixed in position by nut to. The guard is hung from bracket t, and can
be adjusted in height to suit different thicknesses of wood.
When required, I attach a lathe bed to this machine for the purpose of turn-
ing shafts wheel centres and such like; it is placed at right angles to the longi-
tudinal beam C, and fixed there to in line with, but under, the spindle M.
It will thus be seen that I accomplish the object of my invention by means
of a device that is simple in construction & operation, and well adapted to
accomplish the results for which it is intended, and it will be apparent that
changes in and modifications of the construction herein described may be made
without departing from the spirit of my invention or sacrificing its advantages.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved wood-working machine combining circular-saw, band-saw,
boring-mill and lathe, substantially as described and illustrated herein, and for
the purposes set forth.
2. In machines for working-wood of the class herein described, the arrange-
ment and combination of parts for adjusting and fixing the position of a circular
saw, relative to its table and for tightening band saws; substantially as described
and illustrated herein, and for the purpose set forth.
