1, WILLIAM HENRY GOODWIN, of No 120, Victoria Street, in the City of
Toronto, in the County of York and Province of Ontario, Dominion of Canada,
Chart Compiler, do hereby declare the nature of this invention to be as follows:-
This invention is particularly adapted for the production of chionological
charts.
The invention may be briefly described as consisting of a quadrantal chart
blank having one or more scales at one or both of the edges radiating from one
corner thereof and a graduated are extending from one of said radial edges to
the other
The chart blank is preferably of rectangular form and has a scale at two of
the adjoining side edges
An eye is located at the corner of the chart from which the scales converge,
or radiate, and a graduated arc, divided into a number of equal parts, is marked
upon the chart and extends concentrically of the eye from one scale to the
other
Each of these radial time scales is divided into four parts having sub-divisions
further subdivided into fifths, of preferably two and one half inches measure-
ment, and off-set from one another to emphasize the divisional parts and each
of said parts 18 subdivided into twenty parts of preferably one eighth inch
measurement.
Each off-set main divisional part comprises one hundred sub-divisions.
In sing my chait blank to chronologically depict the history of a country,
biography of an individual, institution, or other subject, I find the best results
are attained by constituting each off-set divisional part of the scales, a century
when the history of a country is to be depicted, or, say, a decade when a
biography is to be depicted
In order to make clear the use for which my chart is intended, I will explain
its use in depicting the history of a country, each off-set divisional parts of the
time scales constituting a century
The student being furnished with the historical events, draws an arc on the
chait, making off the period of each event from, say for example, the begining
of the fifteenth to the completion of the nineteenth century. Radial lines can
then be drawn, under the guidance of the arc, to prevent the delimitation of the
extent of proportional area covered by the event, and the chart can then be
written up and colored if desired

Improvements in Ohart Blanks.
I, WILLIAM HENRY GOODWIN, of No. 120, Victoria Street, in the City of
Toronto, County of York, Province of Ontario, Dominion of Canada, Chart
Compiler, 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 is particularly adapted for the production of chronological
charts.
The invention may be briefly described as consisting of a quadrantal chart-
blank having one or more radial scales at the radial edge or edges thereof; but
for full comprehension of same reference should be had to the annexed draw-
ings, forming a part of this specification, and in which-
Fig. 1 is a plan view of the chait-blank, and Fig. 2 an enlarged detail plan
view of a portion of one of the time-scales of the blank
The chart-blank 18 preferably of rectangular form and has a scale w at two of
the adjoining side edges, as shown An eye t is located at the corner of the chart
from which the scales converge, and a graduated aic u, divided into a number of
equal parts, 18 marked upon the chart and extends concentrically of the eyc t
from one scale to the other Each of these radial time-scales w is divided into
four parts g, having subdivisions x, further subdivided into fifths, of preferably
two, and one-half inches measurement, and offset from one another, as at h to
emphasize the divisional parts, and each of said parts is subdivided, as at 2, into
twenty parts of preferably one-eight-inch measurement
It will be observed by referring to Fig 2 that by the subdivisions of the time-
scales each offset main divisional part comprises one hundred subdivisions.
In using my chart-blank to chronologically depict the history of a country,
biography of an individual, or the like I find the best results are attained by
constituting each offset divisional part of the scales a century when the history
of a country is to be depicted or, say, a decade when a biography 18 to be
depicted.
In order to make clear the use fo: which my chart is intended, I will
explain its use in depicting the history of a country, each offset divisional part
of the time-scales constituting a century The student being furnished with the
historical events draws an arc on the chart, marking off the period of each event
from, say, for example, the beginning of the fifteenth to the completion of the
nineteenth century. Radial lines can then be drawn under the guidance of the
graduated ac u to. present the delimitation of the extent of proportional area
covered by the event, and the chart can then be witten up and colored, if
desired
Having now particularly described and ascertained the nature of the saíd
invention and in what manner the same is to be performed I declare that what
I claim 18.—
1 A quadrantal chart-blank having one or more radial scales at the radial
edge or edges thereof substantially as described and for the purpose set forth
2 A quadrantal chart-blank having one or more radial scales at the radial
edge or edges thereof and a graduated aic substantially as described and for the
purpose set forth
