Improvements in Wood Working Machinery or Apparatus.
I, LEON MILTIADES MESSINESI, of Eastcheap Buildings, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows;-
This invention relates to that class of apparatus for sawing, planing, drilling,
turning and otherwise working wood and other materials described in the Speci-
fication of my former Patent No. 14400 of 1897. The object of the invention
is to simplify the construction and increase the utility and efficiency of the
apparatus.
in constructing a machine according to the present invention I provide the
usual support or frame carrying a table which can be adjusted to any suitable
elevation, for example through the medium of a rack and pinion operated by
worm gear, and which can be also adjusted in the horizontal plane by being moved
in guides through the medium, for example, of rotatable screwed rods which may
be actuated by mitre wheels.
The work table proper, which is provided with the usual undercut grooves, is
arranged to slide upon a plate or frame hinged at its centre to the sliding
portion of the table so that it can be adjusted to any desired inclination. To
effect this adjustment I provide one side of the said table with a toothed sector
with which engages a worm mounted upon a spindle adapted to be operated by
hand as desired, the centre of the sector coinciding with the axis around which
the table swings. With this arrangement it will be obvious that by turning the
worm spindle the sector is rotated thereby also turning the table to the desired
position. To enable the table to be clamped in any position to which it may be
adjusted I slot the toothed sector and pass through the slot a rod which extends
through the apparatus to the other side of the table and through a slot in a
similar but untoothed sector attached to the other side of the table. One end
of the rod is provided with a head and the other end is screw-threaded so as to
receive a screwed nut or handle which, when tightened upon the screw-threaded
end, securely holds the table in the position to which it may be adjusted.
The upper part of the frame is provided with a horizontal support or bearing
having a spindle adapted to carry tools, for example a saw and drills, at the nose
of the spindle, the said frame or support being also provided at its upper part
with a work table placed so that it can present work to the upper part of the saw,
This table is arranged so that it can be slid out of operation to make place for
other tools, for example a router or a fixed chisel. which said tools are mounted
in frames adapted to be secured to the arm or support by being inserted into a
lateral guide upon the said support.
I also provide a hanging bracket which can be fitted to the under part of above
mentioned horizontal support and is adapted to receive one end of a spindle
the other end of which is carried in the end of a short shaft adapted to be
rotated as hereinafter described. This spindle is arranged to receive suitable
tools, such as beading tools, routing cutters, chisels or drills set in a horizontal
position.

page_text: The apparatus is driven by a shaft arranged at its lower part and actuated from
any suitable source, the said shaft being provided with a pulley for driving the
upper and lower spindles and the tools by means of belts, any one of which can
be placed in position according as it is required to drive the upper or lower spindle
or the tools; by this means I obviate the disadvantage of having more than one
belt in the machine at a time.
The driving shaft is provided with a friction pulley with which a second
friction pulley mounted upon a fretsaw shaft can be brought into contact by
means of pedal gear, the said fretsaw shaft having a crank adapted, when rotated,
to reciprocate a flexible fretsaw which passes over suitable guide pulleys.
The pivoted table may be provided with a circular rotary work table and means
whereby the said rotary table can be turned intermittently through any desired
predetermined angle.
To simplify the construction of the device for setting out angles described in
my above named former patent I dispense with the strip t¹ and the bisecting bar
or rod w and clamp the two graduated strips t in the desired position by a clamping
screw arranged at the joint. In this case it will obviously be unnecessary to
slot the strips t.
I, LEON MILTIADES MESSINESI, of Eastcheap Buildings, in the City of London,
Merchant. 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 that class of apparatus for sawing, planing, drilling,
turning and otherwise working wood and other materials described in the Speci-
fication of my former Patent No. 14400 of 1897. The object of the invention
is to simplify the construction and increase the utility and efficiency of the
apparatus.
In the accompanying drawings:-
Figure 1 is a side elevation of apparatus made according to the invention:
Figure 2 is a front view thereof:
Figure 3 is a sectional plan of the apparatus:
Figure 4 is a vertical section through the lower part of the apparatus:
Figures 5 and 6 are a rear view and a side view respectively of a portion of the
apparatus illustrating a modified construction:
Figure 7 is a side elevation of a device designed for setting the work at required
angles; and
Figure 8 is an end view thereof.
Referring first to Figures 1 to 4, a is the frame or support of the apparatus, the
said frame being provided with an upper horizontal arm . The lower or main
portion of the frame carries a table consisting of the F-shaped frame bon
which slides the frame b¹, of the part e which is pivoted at to the frame b
so as to swing in a vertical plane and of the table proper which is adapted
to slide horizontally, in a direction at right angles to that in which the frame b
slides in the part . The frame is adjusted in height by means of the rack 12

page_text: and the pinion 63 mounted upon the spindle 64 and adapted to be operated by
the worm wheel 65 and worm 66 mounted upon the spindle 67 the latter having
a squared end to receive an operating handle.
To operate the frame b¹ a screw e is provided which is fixed in lugs e¹, e¹ on
the frame b and engages an internally screw-threaded bevel wheel of gearing
with a bevel wheel f¹ keyed upon a spindle 2 mounted in a bearing secured to the
frame b, the said bevel wheel f being retained in position by a lug 3 secured
to the frame b so that by rotating the spindle the bevel wheel f¹ rotates the
bevel wheel f thereby feeding the sliding table in either direction as desired.
To adjust the table to any desired inclination the following arrangement is made
use of, that is to say, one side of the said table has fitted to it a toothed sector c²
with which gears a worm mounted upon a spindle adapted to be operated
by hand through the medium of the bevel wheel upon the said spindle, which
bevel wheel gears with a second bevel wheel mounted upon a spindle sup-
ported in a bearing on the sliding frame and adapted to be rotated by a
suitable handle which can be fitted upon its squared end: the centre of the
sector coincides with the axis c¹ around which the table c swings. With this
arrangement it will be obvious that by turning the worm spindle the sector e³
is rotated, thereby turning the table proper to the desired position.
To enable the table to be clamped in any position to which it may be adjusted,
the toothed sector has a curved slot formed in it (the curve having the
pivot as a centro) and a rod g is passed through the said slot, the said rod g
extending through the apparatus to the other side of the table and through a slot
in a similar but untoothed sector gattached to the other side of the table.
The end projecting through the sector gl is provided with a head and the
other end is screw-threaded so as to receive a screw-threaded nut or handle g³
which, when tightened upon the said screw-thread, securely holds the table in
the position to which it may be adjusted.
The work-table proper dis provided with the usual undercut grooves d for the
guides and clamps and is adapted, as above mentioned, to slide horizontally upon
the pivoted table c, the adjustment being effected by the usual arrangement of
screw rod and nut.
The table may also be provided with grooves do, do as shewn or with edge grooves
to receive adjustable stops which project over the table and serve for establishing
the position upon the table of successive pieces of similar work to be similarly
treated.
The upper horizontal arm a² of the frame carries a spindle h which is adapted
to be rotated therein and to carry a tool at its front end, for example a saw
a drill, etc. The arm a¹ is also provided at its upper part with a work-table j
so placed that it can present work to the upper part of the saw i. The said
table is mounted on a guide on the upper part of the said arm a¹ in such a
manner that it can be slid back out of operation to make place for other tools,
for instance a router or a fixed chisel, these tools being mounted in frames or
brackets which can be secured to the arm a¹ by being passed into the lateral
guide on the said support.
A hanging bracket can also be provided for being fitted to the under part of
the arm a¹, the said hanging bracket being adapted to receive one end of a spindle
the other end of which is carried in one end of the short shaft 7, which is mounted
in bearings in the arm a¹ and is adapted to be rotated as hereinafter described.
This spindle is arranged to receive single tools such as beading tools, routing
cutters, chisels or drills set in a horizontal position.
With this arrangement of two tool spindles arranged one above the other it is
possible to submit work to two successive operations, such for example as sawing
and grooving, by first raising the work-table set at the required angle so that
the work is cut by the saw mounted upon the upper spindle and then simply
lowering the said table (without altering its angle) to enable the work to be
grooved (or otherwise treated) by the tool upon the lower spindle.

The apparatus is driven by a shaft m mounted in bearings m³ in the lower part
of the frame a, the said shaft being provided with fast and loose pulleys n, n¹
whereby it can be operated from any suitable source of power, and with a pulley
for driving the upper and lower spindles and respectively by means of belts,
either one of which can be placed in position according as it is required to drive
the upper or lower spindle through the medium of their pulleys n², n³; by
this means the disadvantage of having more than one belt on the machine at a
time is obviated.
The driving shaft is provided with friction wheel p with which a second
friction wheel mounted upon a shaft is brought into contact by means of
the counterweighted pedal which is pivoted at 2 and is provided with a
fork which engages a sleeve q' secured to the boss of the friction wheel pl
so that the rotation of the shaft m effects the rotation of the shaft g, the end of
which is provided with a crank r having a crank pin which, on the rotation
of the shaft, reciprocates a fret-saw slides through the medium of the connecting
rod 2. This slides is held in guides and has attached to its two ends a flexible
fret-saw which, when required to be used, is passed over pulleys u, u, u³
suitably secured to the apparatus. By depressing the pedal ' the friction wheels
are disengaged and the saw remains at rest. Slots ³, are formed in the
table proper for the passage of the saw at different inclinations of the table.
The pivoted table may be provided with a circular rotary work-table and means
whereby the said rotary table can be turned intermittently through any desired
predetermined angle.
In Figures 5 and 6 I have shewn a modified construction of table. In this
arrangement the horizontally sliding table is dispensed with and the pivoted
table is formed with transverse grooves d', d, by means of which the work
can be clamped in position, preferably through the medium of a slide working in
the grooves. Lateral grooves c°, c° are also provided to receive adjustable stops
for establishing the position of successive pieces of similar work which has
to be similarly treated.
In this machine also the sliding frame b' is operated by a rack r formed upon
it and with which gears a pinion adapted to be rotated by a hand wheel 23.
To simplify the construction of the device for setting out angles described in
my aforesaid patent I dispense with the basal graduated strip and the bisecting
bar or rod and I clamp the two graduated strips in the desired position by
suitable means such for example as by a clamping screw arranged at the joint;
in this case it will obviously be unnecessary to slot the strips. Or, I may
clamp the two graduated strips by an adjustable cross bai as shewn in Figures 7
and 8 of the accompanying drawing in which w represents the protractor to which
the pivoted graduated strips 1, 2 are applied. the said strips being held in the
position in which they are adjusted by means of the clamping bar r, one end of
which is attached to the strip by a screw and the other end of which is
provided with a screw w which works in an undercut slot in the strip and
has a nut by tightening which the clamping bar can be fixed to the graduated
strip 2.
ware dowels on the sector which engage holes in the strip w¹ for
holding the said strip in position.
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. In wood working machinery or apparatus of the kind described, the employ-
ment of a vertically adjustable frame carrying a horizontally sliding frame in its
