PROVISIONAL SPECIFICATION.
Improvements relating to Combined Callipers and Compasses.
I, WALTHER GLITSCH of Geneva, Switzerland, do hereby declare the nature of this
invention to be as follows:-
This invention relates to combined callipers and compasses which I term "The
universal compass
for engineers, foremen of workmen in manufactories and
the like.
"
The improved compasses which are of very simple and strong construction may be
used for the following purposes.
To draw circles on wood, iron and the like.
To measure the diameter of a cylindrical or spherical object.
To measure the diameter of a hole.
To determine the antipode of a point.
To find the centre of a hole.
To find the centre of a solid cylinder.
To engrave lines on wood or metals and
To measure angles.
The compass answering to all these purposes comprises two main arms which are
connected by a hinged joint and each provided respectively with two branch arms the
whole being combined so as to be folded up into a small space.
One of the main arms is provided around the hinged joint with a graduated disc
and the other with a hand or indicator, the latter being intended to indicate upon
the said disc the angle formed by the said arms.
The improved compass may be constructed in three different ways with regard to
the form of its branch arms and in view of answering the above specified purposes.
1st. Each of the main arms may be provided with two branch arms one having its
end formed with a point and the other having its end bent inward like the arm of a
pair of callipers.
2nd. The said four branch arins may be replaced by two, each provided with a
straight point and with a lateral projection at some distance therefrom.
3rd. The branch arms may be provided with straight points and combined with
removable ends or points which may be either screwed to the said straight points or
fixed to them in any way whatever.

COMPLETE SPECIFICATION.
Improvements relating to Combined Callipers and Compasses.
I, WALTHER GLITSCH, of Geneva, Switzerland, 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 :-
.
The invention relates to combined callipers and compasses which I term the
"universal compass" for engineers, foremen or workmen in manufactories and
the like.
The improved compasses which are of very simple and strong construction may be
used for a variety of different purposes as hereinafter mentioned.
In the accompanying drawing
Figure
shows the compass adapted for drawing circles on wood, iron and

page_text: Figure 2 shows the same applied to measure the diameter of a cylindrical or
spherical object.
Figure 3 shows the same arranged to measure the diameter of a hole.
Figure 4 shows the compass arranged for determining the antipode of a point.
Figure 5 shows the same arranged for finding the centre of a hole.
Figure 6 shows the same arranged for finding the centre of a solid cylinder.
Figure 7 shows the compass adapted to engrave lines on wood or metals, and
Figures 8 and 9 show the compass in its folded position.
Figure 10 shows the same arranged for measuring angles.
The compass answering to all these purposes is represented open in Figure 2 and
folded in the Figures 8 and 9 of the accompanying drawing.
Two arms A. B are connected by a hinged joint C, and each provided respectively
with two branch arms E D and G H the whole being combined so as to be folded
into a small space as shown in Figures 8 and 9.
One of the main arms B is provided around the hinged joint with a graduated
disc and the other A with a hand or indicator g the latter being intended to
indicate upon the said disc the angle formed by the said arms A and B as shown in
Figure 10.
The improved compass may be constructed in three different ways with regard
to the form of its branch arms and in view of answering the above specified
purposes.
1st. Each of the main arms may be provided with two branch arms D E or G H,
one E having its end formed with a point and the other D having its end bent inward
like the arm of a pair of callipers.
2ndly. The said four branch arms may be replaced by two, each provided with a
straight point d' and with a lateral projection d" at some distance therefrom.
3rdly. The branch arms D E G H may be provided with straight points and
combined with removable ends or points e, i ork which may be either screwed to the
said straight points or fixed to them in any other way.
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 :-
First A compass formed of the arms A and B hinged at C and provided with a
graduated segment and with an indicator 9, each of the arms A and B bearing
hinged thereto an arm as at D and having a point d' and a lateral prejection di
substantially as shown and for the purpose specified.
Second A compass formed of the arms A and B hinged at C and provided with
a graduated segment fand with an indicator g the said arms A and B having other
arms E and H pivoted thereto substantially as shown and for the purpose specified.
Third A compass formed of the arms A and B hinged at C and provided with a
graduated segment f and with an indicator g, the said arms A and B bearing other
arms pivoted thereto, one formed as at E with a sharp point, and one as at G, the latter
being arranged to be combined with the parts e, i or k substantially as shown and
described and for the purpose specified.
Fourth A compass formed of the arms A and B hinged at C and provided with a
graduated segment and with an indicator 9, the said arms A and B having hinged
to them one arm formed as at G and disposed so as to be combined either with a
sharp point k or with a bent point i or e fixed in any way whatever to said foot G
substantially as shown and for the purpose specified.
