PROVISIONAL SPECIFICATION.
Improvements in or relating to Bar-bells and Indian Clubs.
I, ALEXANDER STURROCK, of The High School, Dundee, in the County of
Forfar, Scotland, Gymnastic Instructor, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in or relating to bar-bells and Indian
clubs, the object being to show, mark, or indicate if the pupils are in correct
position at certain periods, during their exercises.
In carrying out my invention according to one modification, as applied to bar-
bells, I mount upon the bar an index ball or ring so arranged as to slide backwards
and forwards upon same, according as the one or the other extremity of such
bar-bell is elevated or depressed; its travel being limited to the central portion of
the bar by means of two fixed rings. Each extremity of the bar-bell is provided
with suitable bells. The object of the index ball is to indicate by sight or sound
that each pupil is in the correct position and is keeping the correct time.
In a second modification may employ two index balls, one at each extremity
of the bar-bell and mounted to slide between fixed points as in my first
modification.
In a third modification, as applied to Indian clubs, the index ball is mounted near
the outer extremity of the club, and is free to slide to and fro between two fixed
points as the club is elevated or depressed, thus indicating if correct time or
position is being kept.
As the index ball when it comes against one or other stop makes a distinct
sound, it is obvious that a number of pupils may be exercised and time kept without
the aid of music.

COMPLETE SPECIFICATION.
Improvements in or relating to Bar-bells and Indian Clubs.
I, ALEXANDER STURROCK, of The High School, Dundee, in the County of
Forfar; Scotland, Gymnastic Instructor, 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 or relating to bar-bells and Indian
clubs, the object being to show, mark, or indicate if the pupils are in correct
position at certain periods, during their exercises.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended two explanatory sheets of drawings in which the same reference numerals
are used to indicate corresponding parts in all the figures where shown.
Figure 1. (Sheet 1.) illustrates a bar-bell provided with an index ball;
Figure 2. a musical bar-bell;
Figure 3a har-hell with index ball and bolls and
.

page_text: Figure 4. another modification of bar-bell provided with two index balls.
Figure 5. (Sheet 2.) illustrates an Indian club provided with an index ball;
Figure 6. an Indian club with an index ball and bell;
Figure 7. illustrating the type of bell preferably used in combination with the
bar-bells or Indian clubs.
In carrying out my invention according to one modification, as applied to bar-
bells, sec Figures 1. 2. and 3, I mount upon the bar 10. an index ball or ring 11. so
arranged as to slide backwards and forwards upon same, according as the one or
the other extremity of such bar-bell is elevated or depressed; its travel being
limited to the central portion of the bar by means of two fixed rings 12.
Each extremity of the bar-bell is provided with suitable balls or bells 13. The
object of the index ball is to indicate by sight or sound that each pupil is in correct
position and is keeping correct time, that is to say if such pupil elevates or depresses
the bar-bell sufficiently and at the right time.
In a second modification, see Figure 4, I may employ two index balls 11, one at
each extremity of the bar-hell and mounted to slide between fixed points 12. and 13.
as in my first modification. It is obvious that bells may be combined with this
modified bar-bell, as previously described and illustrated.
In a third modification, as applied to Indian clubs, see Figure 5, the index
ball 11. is mounted near the outer extremity of the club, and is free to slide to and
fro between two fixed points 14. and 15. as the club is elevated or depressed, thus
indicating if correct time or position is being kept. I need scarcely say that when
the club is swung round rapidly the index ball will not slide to and fro, but will
remain at its greatest distance from the centre of rotation. As the index ball,
when it comes against one or other stop makes a distinct sound, it is obvious that a
number of pupils may be exercised, in a manner well known to any gymnastic
instructor, and time kept without the aid of music.
n
I wish it to be particularly understood, that I do not limit myself to the precise
details of construction herein before described and illustrated on the annexed
drawings, but that I hold myself free to make such changes and alterations as
conform with the disposition and scope of my invention.
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
--
(1.) The combination with a bar-bell of an index ball substantially as described
und for the purposes set forth.
(2.) The combination with a bar-bell of an index ball and bells, substantially as
described and for the purposes set forth.
(3.) The combination of a bar-bell with two index balls, substantially as described
and for the purposes set forth.
(4.) The combination of a bar-bell with two index balls and bells, substantially as
described and for the purposes set forth.
the
(5.) The combination with an Indian club of an index ball, substantially as and for
purposes set forth.
(6.) The combination with an Indian club of an index ball and bell, substantially as
and for the purposes set forth.
(7.) The combination of a bar-bell with the type of bell illustrated by Figure 7,
as described.
(8.) The combination of an Indian club with the type of bell illustrated by Figure 7,
as described.
