An Improved Angle or Square.
I, PETER KNOBEL of Flums, Switzerland, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to an improved angle or square made of bar metal
as for example iron formed at opposite sides or edges with two longitudinal beadings
channels or ridges which enable the square to be made of comparatively small
weight, but considerable stiffness, thereby rendering it very suitable for various
purposes. When employed as a measuring or set-square by workmen such as
carpenters, bricklayers, stone-masons, and joiners its legs will not bend even when
they are made of considerable length and are not supported at their ends. This
property, which results equally from the small weight and the great stiffness of the
square, ensures accurate setting-off, measuring or aligning, whilst its small weight
allows of its being easily manipulated with one hand.
The squares heretofore ordinarily employed are of considerable weight in
consequence of the full rectangular cross section of their legs, and when the legs
are long the weight causes the same to bend and spring in such a manner as to
render the manipulation of the squares very inconvenient.
Another application of angles or squares according to this invention consists in
its employment as a fillet or beading, as for example, in shop-fittings or furniture,
and in general as an angle for connecting or stiffening two pieces of wood, or
boards or fillets forming together an angle or corner, the stiffness of the angle
ensuring rigidity of connection of the pieces of wood thus connected together.
The legs of the angle need not in all cases be at right angles to each other, but
may be at any other desired angle to each other.
In the accompanying drawings,
Figs. 1 and 2 show respectively a plan and a cross section, of an angle or square
constructed according to this invention.
The two beaded raised or channelled edges a which impart the aforesaid stiffness
to the legs of the angle or square, have two inclined edge-surfaces which may be
divided according to any desired scale when the square is to be employed as a
measuring or setting off square. The strip or portion b of metal situated between
the two beaded, or raised edges may be provided with a divided scale which is
protected by the said beaded or raised edges from rubbing against rough surfaces,
such as stones and the like. A measuring angle or square of the kind described
may be made, of one piece of metal as illustrated; or the two legs may be connected
together on the diagonal line x-x, in which case the joint at the apex of the angle
may be fished or scarved by means of a small angle of similar cross-section.
When the angle is intended for use as a beading, fillet or furniture, it is preferably
made of one piece of metal.

page_text: 1, PETER KNOBEL of Flums, Switzerland, Manufacturer 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 has reference to an improved angle or square made of bar metal
as for example iron formed at opposite sides or edges with two longitudinal beadings,
channels or ridges which enable the square to be made of comparatively small
weight, but considérable stiffness thereby rendering it very suitable for various
purposes. When employed as a measuring or set square by workmen such as
carpenters, bricklayers, stone-masons and joiners its legs will not bend' even when
they are made of considerable length and are not supported at their ends. This
property, which results equally from the small weight and the great stiffness of the
square, ensures accurate setting-off, measuring or aligning, whilst its small weight
allows of its being easily manipulated with one hand.
The squares heretofore ordinarily employed are of considerable weight in
consequence of the full rectangular cross section of their legs being retained and
when the legs are long, the weight causes the same to bend and spring in such a
manner as to render the manipulation of the squares very inconvenient.
Another application of angles or squares according to this invention consists in
its employment as a fillet or beading, as for example, in shop-fittings or furniture,
and in general as an angle for connecting or stiffening two pieces of wood; or boards
or fillets forming together an angle or corner, the stiffness of the angle ensuring
rigidity of connection of the pieces of wood thus connected together. The legs of
the angle need not in all cases be at right angles to each other, but may be at any
other desired angle.
Referring to the drawings filed with my Provisional Specification,
Figs. 1 and 2 show respectively in plan and cross section, an angle or 'square
constructed according to this invention.
.:
The two beaded raised or channelled edges a which impart the aforesaid stiffness to
the legs of the angle or square, have two inclined edge-surfaces which may be
divided according to any desired scale when the square is to be employed as a
measuring or setting-off square. The strip or portion of metal situated between
the two beaded, or raised edges may be provided with a divided scale which is
protected by the said beaded or raised edges from rubbing against rough surfaces,
such as stones and the like.
A measuring angle or square of the kind described, may be made of one piece of
metal as illustrated; or the two legs may be connected together on the diagonal
line x-x, in which case the joint at the apex of the angle may be fished or scarved
by means of a small angle of similar cross section.
When the angle is intended for use as a beading, fillet or furniture, it is preferably
made of one piece of metal.
Having now, particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
An angle or square composed of metal bar the form of which in cross section is

page_text: that of undulating or corrugated prominences which rise obliquely from the
longitudinal edges, substantially as described and shown.
