PROVISIONAL SPECIFICATION.
Improvements in Dividers.
I ADALBERT GOERINGER of Maximiliansplatz 17, Munchen in the Empire of
Germany, Medical Practitioner do hereby declare the nature of this invention to
be as follows:-
:-
This invention consists in an improved divider or compasses having three points
so contrived, that these points always lie in relation to each other at certain
proportional distances, namely such that the distance from the one outer point to
the middle point bears the same proportion to the distance between the middle
point and the other outer point, that the latter distance does to the total distance
between the two outer points.
It will thus appear that this divider if the two outer points are placed at the
two extremities of a given finite straight line A. C. will with its middle point so
divide that line at B that the proportion A. B: BC:: BC: A C.
This divider consists of two main legs pivoted together and of two subsidiary
legs which bear the necessary proportions one to the other and to the main legs
as regards their length, these legs are pivoted respectively to the two main legs
to lie parallel each to the other of the main legs; while they are also pivoted
together at or near their points to form the middle point, which the dividers are
intended to find on the line divided.

COMPLETE SPECIFICATION.
Improvements in Dividers.
I, ADALBERT GOERINGER, of Theresienstrasse 82 Munich, in the Empire of
Germany, Medical Practitioner, 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 consists in an improved divider or compasses having three points
so contrived that these points always lie in relation to each other at certain
proportional distances, namely such that the distance from the one outer point to
the middle point bears the same proportion to the distance between the middle
point and the other outer point, that the latter distance does to the total distance
between the two outer points.
The accompanying drawing illustrates this divider which consists of two main
legs X Y pivoted together and of two subsidiary legs l m which bear the necessary
proportions one to the other and to the main legs as regards their length, these legs
are pivoted respectively to the two main legs X Y to lie parallel each to the other
of the main legs, while they are also pivoted together at or near their points Z
to form the middle point which the dividers are intended to find on the line
divided.
It will thus appear that this divider if the two outer points are placed at the
two extremities of a given finite straight line A. C will with its middle point Z so
divide that line at B that the proportion A B: B C:: BC: A C.
The proportion of the effective lengths of the legs and m is as A B to B C.
In place of the subsidiary legs 1 m, an elastic cord with a bead threaded on it may
join the extremities of the legs X Y at A C, the bead marking the point B.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
A divider or compasses having the two main legs X Y pivoted together with
two subsidiary legs I'm or equivalent device between them adapted to divide in
the proportion AB: BC:: BC: A C.
