Improvements in Set Squares.
HUON ARTHUR MATEAR 6, Stanley Street Liverpool in the County of
Lancaster Architect do hereby declare the nature of this invention to be as
follows:-
This invention is for improvements in set squares as used by architects and
others, and is for the purpose of setting off any angle-acute or obtuse—that may
be required. In practice I cause to be attached a movable limb to a right angle
set square-hereinafter called the "rectangle "-having slots in the perpendicular
limb and also in the horizontal limb of the said "rectangle."
"
The movable limb aforesaid is secured by runners fitting and sliding easily in the
slots of the perpendicular and the horizontal limbs of the "rectangle so that
any angle required can be set off by simply putting the movable limb in the
required position.
On the horizontal limb of the "rectangle," a scale of the various degrees may be
marked.
The whole may be made in any suitable wood, ivory, bone, metal, alloy, or
composite material.
The sides of the slots and the runners previously mentioned may be made in
silver, brass, or aluminium, or of any desirable material.
