COMPLETE SPECIFICATION.
A Tool for Cutting Wood to Mitre or other Angles.
I, JOHN REAP, of No. 147 Chadwick Road, Camberwell, in the County of
Surrey, 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:-
:-
My invention relates to a tool which may be placed or fixed on a carpenter's
bench for cutting wood, such for instance as the ends of bars to constitute framings,
to mitre or other angles. The tool according to my invention is constructed as I
shall describe referring to the accompanying drawings.
Fig. 1 is a side view,
Fig. 2 is an end view and
Fig. 3 is a part sectional plau.
On a table A on which may be fixed dogs for holding or guiding the bars of
wood operated on, I pivot at one side by a horizontal bolt B a segment C which
can be moved in a vertical plane in face of a stationary slotted segment D, and can
be clamped thereto by a thumb screw E. The circumference of either or both the
segments C and D is graduated so that C can be set to any angle within a certain
range, relatively to D.
From the segment C projects a plate F on which is pivotted at H a slotted
plate G carrying a round edged knife K. There is also pivotted on the plate F
at L a slotted lever M engaging in its slot a stud N projecting from G.
The tool is worked in the following manner.
The segment C being set relatively to D and clamped to the angle to which the
end of the wood is to be cut, the wood is placed on suitable bearers on the table A,
held by or guided between dogs which may be fixed so as to guide the bar at any
angle relatively to the edge of the table A, but which should hold the wood at
such a level that its lower side is in the plane of the axis of the pivot B.
The operator then moving up and down the lever M which may be of greater or
less length according as more or less power is required, causes the knife K as it
descends passing the edge of the table A to cut the wood to the angle determined
by the position of C relatively to D and by the position of the dogs or guides on
the table A. It is often convenient to give a circular shape to the end of a bar
of wood cutting the end either perpendicularly or obliquely to the face of the
wood.
In order to effect this operation I provide a slide P which can slide between
guides Q fixed on the table A and can be clamped where required by a bolt
passing through a slot of the slide. On this slide there is a sharp stud R on which
as on a centre a bar of wood can turn, presenting its edge to the knife which cuts
it in circular form (as indicated by the dotted edge lines S) to a radius determined
by the distance at which the stud R is set back from the edge of the table A. As
it is necessary that the meeting faces of the parts F G and M should work against
each other without shake or looseness, I make the pivot pins H and L with conical
heads fitting in coned holes in G and M respectively, and with screw threaded
shanks which screw into F so as to press the working faces of the parts more or
less closely together, and, having thus adjusted the parts, I secure the pivot pins in
position by lock nuts.

tion and in what manner the same is to be performed, I declare that what I
claim is :-
A tool for cutting wood to mitre or other angles, substantially as described and
illustrated by the accompanying drawings.
