PROVISIONAL SPECIFICATION.
Improvements in Drawing Boards.
We JAMES ASHFORD, of 179 Aston Road, in the City of Birmingham,
Photographic Apparatus Manufacturer, and WILLIAM TYLAR, of 57 High
Street, Aston New Town, near the City of Birmingham, Manufacturer, and
DRUID GRAYL, Hatfield, Erdington, Warwickshire, Lyric Author, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in drawing boards, and chiefly intended
for such boards that are used for scholastic or educational purposes, but which
may be also applied to drawing boards used for more advanced use.
It consists in the combination with the edge or edges (or near thereto) of the
boards, a detachable or non-detachable marked rule, scale, or other divided
measurements, lines or divisions, wherefrom distances, measurements, or angular
lines may be made, without the use of a separate rule or protractor &c.
These measurements or lines or figures &c., may be impressed direct upon the
board itself, or they may be made upon a separate strip, the said strip being
afterwards attached thereto; as for instance, by inlaying, or by means of a
metallic edge being screwed thereon, or being made to clip or bind such edge; or,
a removable strip may be thus affixed by pins or screws, which may be readily
removed and others substituted therefor when required; or in other cases a
marked paper strip may be gummed thereon; or if preferred, we may make saw
cuts in the said edges, at given distances apart, into which may be glued dissimilar
coloured pieces of wood &c., which would thus form the divisional lines required.

COMPLETE SPECIFICATION.
Improvements in Drawing Boards.
We JAMES ASHFORD, of 179 Aston Road, in the City of Birmingham,
Photographic Apparatus Manufacturer, and WILLIAM TYLAR, of 57 High
Street, Aston New Town, near the City of Birmingham, Manufacturer, and
DRUID GRAYL, Hatfield, Erdington, Warwickshire, Lyric Author, 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 improvements in drawing boards, and chiefly intended
for such boards that are used for scholastic or educational purposes, but which may
be also applied to drawing boards for more advanced use.
It consists in the combination with the edge or edges (or near thereto) of the
boards, a detachable or nondetachable marked rule, scale, or other divided
measurements, lines or divisions, wherefrom distances, measurements, or angular
lines may be made, without the use of a separate rule or protractor &c.
It
In order to explain more clearly this our invention, we have appended hereunto
an illustrative drawing showing how the edges of the board may be marked.
will nevertheless be readily seen that the particular character and disposition of
such marks may be varied.
As shown Along the edges of the board A, is marked the measurement

page_text: scale B, B1, B2 & B3, of inches, which are further subdivided similar to an ordinary
rule;
or such marking may be that of proportionate scale measurements.
At C, C, and C2, is marked angular measurements protracted from the centre D,
while similar measurements are again shown at E, E and E², which are protracted
from the centre 'F, so that such angles may be measured from the side G, or
⚫end H.
These measurements or lines or figures &c., may be impressed direct upon the
board itself, or they may be made upon a separate strip, the said strip being
afterwards attached thereto; as for instance, by inlaying, or by means of a
metallic edge being screwed thereon, or being made to clip or bind such edge; or,
a removable strip may be thus affixed by pins or screws, which may be readily
removed and others substituted therefor when required; or in other cases a
marked paper strip may be gummed thereon; or if preferred, we may make saw
cuts in the said edges, at a given distances apart, into which may be glued
dissimilar coloured pieces of wood &c., which would thus form the divisional lines
required.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In drawing boards, the combination' therewith of its edges being marked with
measurements, scales, or angles &c., in the manner set forth and for the purposes
specified.
