page_text: We ROBERT JOSEPH RASTRICK of Southsea manufacturer and GEORGE HUGHES
of Titchfield Carpenter both in the. County of Hants do hereby declare the nature
of our invention to be as follows:-
Our invention consists of a machine for cutting mitres of any desired size and
is equally applicable for cutting other angles.
According to this invention we fit on to a table capable of extension as hereafter
described an adjustable set square that is to say we pivot at one end two flat pieces
of wood, metal or other suitable material on to the said table the other ends being
fitted with thumb screws working in a slotted quadrant piece also fixed on said
table so that the said pieces which form the sides of the set square may be set to
any desired angle. To the back part of the aforesaid table we fit two uprights
suitably grooved so that a blade or cutter may work vertically between same, this
blade or cutter we prefer to work by means of a screw fitted in a cross piece
connecting the aforesaid uprights at or near the top. We make the aforesaid table
with sliding top actuated preferably by a screw so as to adapt it according to the
size of the material on which the mitre or other angle is to be cut. In order to
cut a mitre or other angle with a machine constructed as above it is simply
necessary to adjust the set square to the desired angle, tighten up the thumb
screws in order to fix same firmly and then place the straight edge of the wood
or other material to be cut against the set square and screw down the blade or
cutter when the desired mitre or other angle will be clearly cut.
We may graduate the aforesaid quadrant piece so that the desired angle may be
Bet with facility.
The above may be worked by hand or power.

We ROBERT JOSEPH RASTRICK of Southsea manufacturer and GEORGE HUGHES
of Titchfield Carpenter both in the County of Hants, do hereby declare the nature
of our invention and in what manner the same is to be performed to be parti-
cularly described and ascertained in and by the following statement:-
According to this invention we fit on to a tablo capable of extension as hereafter
described an adjustable set square that is to say we pivot at one end two pieces of
wood, metal or other suitable material on to the said table these, being fitted with
thumb screws working in a slotted quadrant piece also fixed on said table so
that the said pieces which form the sides of the set square may be set to any
desired angle.
To the back part of the aforesaid table we fit two uprights suitably grooved so
that a blade or cutter may work vertically between same this blade or cutter we
prefer to work by means of a screw fitted in a cross piece connecting the aforesaid
uprights at or near the top.. We make the aforesaid table with sliding top actuated
preferably by a screw so as to adapt it according to the size of the material on
which the mitre or other angle is to be cut. In order to cut a mitre or other
angle with a machine constructed as above it is simply necessary to adjust the set
square.to the desired angle tighten up the thumb screws in order to fix same firmly
and then place the straight edge or the wood or other material to be cut against
the set square and screw down the blade or cutter when the desired mitre or other
angle will be cleanly cut.
We may graduate the aforesaid quadrant piece so that the desired angle may be
set. with facility.

And in order to explain our said invention more fully we will refer to the sheet
of drawings accompanying this specification in which figure 1 shews perspective
view of a machine constructed according to our said invention and fig. 2 is a plan
of table and bed portion of same drawn to a smaller scale. The same letters are
employed in both figures to denote the same parts A shews the table sliding in
grooves e so as to extend it when necessary by means of the screw F.; B. B. shew
the adjustable pieces forming the set square fixed by means of nuts and screws C.-C.
D is the slotted quadrant piece. E is the bed of machine. G is the knife fixed to
the piece H working in the vertical slots formed in the uprights J. J. I is the
screw to actuate the knife G this screw works through the cross piece Jand is
operated by means of the handle i. In order to cut a mitre or other angle with
a machine constructed as above the material K to be cut is set against the pieces B
as shewn in figure 2 these pieces having first been fixed at the desired angle the
knife G being then brought down by means of the screw I cuts the desired angle
on the piece (or pieces K if the two are to be cut at once).
By the above described machine mitres and other angles may be accurately and
cleanly cut. The machine may be constructed so as to be worked by power.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
A machine for cutting mitres and other angles of the adjustable set pieces B. B.
quadrant piece D, knife G, and sliding table A all substantially as and for the
purposes set forth.
