PROVIDIUNAL SPECIFICATION.
An Improved Paper Ruler.
I, ARTHUR ALEXANDER GOVAN, of -15 Renfield Street, Glasgow, North
Britain, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved paper ruler, and consists of a hollow
tube of glass or other material of a transparent character, said tube being closed
or capped at either or both ends either permanently or removably by stoppers or
caps of cork, wood, gutta-percha, or other like material. The ruler is intended to
hold and expose to view a calendar, architect's scale, multiplication table or other
document for reference as occasion arises. The end caps may be made either in
line with the surface of the ruler; or may project somewhat beyond the surface, so
as to raise the ruler from the surface of the paper.

QUMI UMIE DI MULTIVATION.
An Improved Paper Ruler.
1, Arthur ALEXANDER GOVAN, of 15 Renfield Street, Glasgow, Merchant, 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 relates to an improved paper ruler, and consists of a hollow
tube of glass or other material of a transparent character, said tube being closed
or capped at either or both ends either permanently or removably by stoppers or
caps of cork, wood, gutta-percha, or other like material. The ruler is intended to
hold and expose to view a calendar, architect's scale, multiplication table, advertise-
ment, or other document for reference as occasion arises. The end caps may be
made either in line with the surface of the ruler or may project somewhat beyond
the surface so as to raise the ruler from the surface of the paper.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one explanatory sheet of drawing of which
A is the hollow tube; B B the stoppers or caps, which preferably have their ends of
a greater diameter than the tube A so as to raise the ruler from the surface of
the paper, as well as to make it less liable to be broken in laying it down after use,
or in the event of its falling. C is the calendar, which is placed inside the hollow
tube A, and is exposed to view through the glass or other transparent material of
which the ruler is made.
Of course in place of a calendar, as already explained, an architect's scale,
multiplication table, advertisement, or other document for reference may be placed
inside the tube.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A paper ruler constructed substantially as and for the purposes hereinbefore
described and shown on the drawing hereunto annexed.
Dated this 28th day of September 1891.
