Improvements in and Connected with Pencilcases and Drawing
Instruments.
I, FRANCIS OBRÉ FERGUSON of Gothic Cottage Goldhawk Road Hammersmith
London Architect and Surveyor assisting in the Estate department of the London
and North Western Railway Company at Euston Station London do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to provide an ordinary pen and pencil and dividers
or a bow pencil, or a bow pen protected by a case of such a form as to permit of
portions of mathematical scales as used by Surveyors and such like being shewn and
provided on same in a portable and convenient form.
I do not confine myself to any particular form for the case.
I prefer to carry out my invention in the following manner
Within a hexagon shaped tubular case and telescopic by preference I provide a pair
of dividers, or a bow pen, or a bow pencil or a combination of either and which can
be easily taken out of the case when required for use and also an ordinary pencil or
a combination of an ordinary pen and pencil. I also provide and mark a portion of
a scale on each of the exterior sides of the case which is made of metal or other
suitable material so that if the case be a hexagon shape there will be six different
scales and if telescopic there will be twelve parts of various scales and multiplied
according to the number of tubes.
I now describe the practical use of my invention. Example. To take a dimension
between two separate points on a plan drawn to a scale and probably having no scale
shewn on it. Seek the same scale on the case as the plan is drawn to and detach the
dividers and open out the legs of saine to say ten feet of the given scale, then find
how many ten feet there are between the two points. Say there are five times ten
feet and a portion less. Reduce the legs to the less or remaining portion and apply
it to the scale. The five tens together with the remaining portion will give the
total length. By a similar process any given length or dimension can be applied to
a plan drawn to a scale.

I FRANCIS OBRÉ FERGUSON of Gothic Cottage Goldhawk Road Hammersmith in
the County of Middlesex London Architect assisting in the Estate department of
the London and North Western Railway Company at Euston Station London 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:
The object of my invention is to provide a pencil-case and a pair of dividers or
compasses and a number of scales used for drawing, purposes in a convenient form.
I prefer to carry out my invention in the following manner. Within an octagonal
shaped pencil-case I provide a pair of compasses which can be easily taken out when
required for use and also a pencil. I also provide and mark à scale on each of the
exterior sides of the case. I do not confine myself to any particular manner of
marking the scales which may be stamped printed or engraved. Nor to any particular
form for the case which may be hexagonal or circular and also telescopic and made
of any suitable metal or material such as gold silver aluminum nickel. Nor to any
particular compass. The case will require a long slot in the outer tube when made
telescopic and circular on sectional plan.
The compasses fit tightly into the case when not in use.
By means of the dividers and scales any plan or map may be measured if drawn
to a given scale and marked with the pencil.
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
1. In pencilcases having scales marked and provided on same the combination
and addition of drawing compasses operating as and for the purposes herein set
forth.
2. Pencilcases forming an exterior case and protection for drawing compasses.
