COMPLETE SPECIFICATION.
Improvements in Rulers.
I, JOHN WILLIAM SMITH of Number 159, Main Street, Bingley in the County of
York, Hoisery 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, that is to say :-
It relates to improvements in rulers applicable for drawing lines and consists
of forming said rulers in such a manner that they may be cheaply produced
and yet be more efficient for the varied purposes to which they may be applied, than
those heretofore employed.
Such being the nature of my said invention in order that same may be readily
understood, I have hereunto appended a sheet of drawings illustrative thereof, fig. 1 of
which is a top or side view of my improved ruler and fig. 2 is end view thereof, while
fig. 3 shews same in perspective.
The object of this invention is attained by forming the rulers a somewhat semi-
circular in cross section or what may be termed half round, as is shewn by figs. 2
and 3.
The half-round or semicircular part (as at 6) is for contact with the paper or other
object upon which the lines have to be drawn, while the upper or flat surface c is for
contact with the fingers of the user, a rib or raised strip d being formed along one or
other of the outer edges of the flat part c so as to facilitate the holding of the ruler a
while in use, the said rib d lending a kind of leverage to the fingers of the user as
well as forming more ample hold for facilitating the movements of the ruler.
The upper surface c or any portion or part of the ruler may be graduated for
ineasuring purposes as is shown by fig. 1, or not as may be desired.
