PROVISIONAL DIMITIVATION,
Improvements in Fixed and Portable Electrically Driven Circular
Sawing, Moulding, Rebating, Planing, and Surfacing Machinery.
GEORGE CAMERON, Foreman Saw Miller, 13, Hayburn Street, Partick, Glasgow,
do hereby declare the nature of this invention to be as follows:-
A fixed base of cast iron or other suitable material with circular flange or race
at top.
An ordinary trolley on castors, road wheels or rail wheels, upon which is secured
a base of cast iron or other suitable material, with circular flange or race at top.
Carried on the flange or race at top of fixed, or top of trolley base, is a frame or
distance piece of cast iron or other suitable material, in one or more parts, turned
at bottom to suit, and slotted radially to allow a movement of 90°, the object
being that in a confined space, cross cut or rip sawing, moulding, rebating,
planing and surfacing may be executed by radiating the frame or distance piece
to the required angle. Provided on the flange or race are two stud screws, quick
pitch thread, passing through radial slots on bottom of frame or distance piece,
thereby acting as guides in the process of radiation; these stud screws having
handle nuts for securing frame or distance piece after radiation, such radiation
to be obtained by hand, or by worm and worm quadrant conveniently fixed.
The frame or distance piece is prepared for the reception of work table or bench,
and also for carrying the saw or other tool spindles or heads.
On and in the confines of frame or distance piece is seated or suspended an
electric motor acting directly on saw or other tool spindles or heads, the electric
current being obtained by means of an ordinary peg switch or other device in
connection with constant cable.
This invention consists of the radial movement and in the portable radiating
form is especially adaptable in extensive wood works, shipyards, public buildings
and the like, wherever sufficient electric force is obtainable, and in the fixed
radiating form for working machines at various angles at will.

I, GEORGE CAMERON, late of 13, Hayburn Street, but now of 673, Dumbarton
Road, Partick, in the County of the City of Glasgow, North Britain, do hereby
declare the nature of this invention and in what manner the same is to be per-
DQ17

page_text: formed
to be particularly described and ascertained in and by the following
statement:-
This invention relates to a fixed base of cast iron or other suitable material
with circular flange or race top.
In order that my invention may be properly understood and readily carried
into effect, I have hereunto appended one sheet of drawings, of which,
Figure 1 is a front elevation of my improved sawing machinery.
Figure 2 is an end view, and
Figure 3 is a plan corresponding to Figure 1.
A, represents an ordinary trolley on castors, road wheels, or rail wheels, upon
which is secured a base B of cast iron or other suitable material with circular
flange or race Cat top, Figure 3. Carried on the flange or race C at top of
fixed base or top of trolley base, is a frame or distance piece D of cast iron or
other suitable material in one or more parts turned at bottom to suit and slotted
radially or concentrically by the circular grooves E to allow a movement of 90°,
the object being that in a confined space, cross-cut or rip sawing, moulding,
rebating, planing, and surfacing may be executed by revolving or moving the
frame or distance piece to the required angle.
Provided on the flange or race are two stud screws F and G, quick pitch
thread, passing through radial or concentric slots or grooves E on bottom of
frame or distance piece D, thereby acting as guides in the process of radiation,
these studs and G having handle nuts H and I for securing frame or distance
piece D after radiation, such radiation to be obtained by hand, or by worm and
worm quadrant conveniently fixed. The frame or distance piece D is prepared
for the reception of work table or bench, and also for carrying the saw or other
tool spindles or heads. On and in the confines of frame or distance piece D
is seated or suspended an electric motor acting directly on saw or other tool
spindles or heads, the electric current being obtained by means of an ordinary
peg switch or other device in connection with constant current, but which forms
no part of my present invention. This invention in the portable form is
especially adaptable in extensive wood works, shipyards, public buildings and
the like, wherever sufficient electric force is obtainable.
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;
-
In fixed and portable circular sawing, moulding, rebating, planing and surfac-
ing machinery the arrangement of a base plate mounted on a trolley or otherwise
rigidly fixed to the ground in combination with a movable frame slidably sup-
ported on said base plate and capable of being turned through and clamped to
any angle up to ninety degrees by means of screw studs fixed to the base plate
and working in radial or concentric grooves formed in the movable frame, sub-
stantially as described and shown on the accompanying drawings.
