PROVISIONAL SPECIFICATION.
Improvements in Musical Tops and other Rapidly Revolving Toys.
I, EDWARD HALL of 1, Finkin Street Grantham, in the County of Lincoln,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to make tops or other rapidly revolving toys to
produce a loud musical sound.
The tops may be made of wood or any other suitable substance.
My improvements in an ordinary spiked top consists of a hollow formed in the
centre of the top, there are four holes formed at right angles to the above mentioned
hollow, and at right angles to each other, and passing through the greatest circum-
ference of the top, at the bottom of the hollow before mentioned is a sunken socket
into which the lower end of a whistle is forced, the upper end of the whistle being
on a level with the upper part of the top. A ring of any suitable substance is
fastened round the upper part of the whistle, and fits tightly into the neck of the
first mentioned hollow, holding the whistle firmly in its place in the centre of the
top, and prevents the air passing into the top except through the whistle.
The whistle can be made of metal or any other suitable material.

COMPLETE SPECIFICATION.
Improvements in Musical Tops and other Rapidly Revolving Toys.
I, EDWARD HALL, of 1, Finkin Street, Grantham, in the County of Lincoln,
Engineer, 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 object of my invention is to make tops or other rapidly revolving toys to
produce a loud musical sound.
The tops may be made of wood or any other suitable substance.
My improvements in an ordinary spiked top consists of a hole or hollow formed
in the centre of the upper part of the top. There are four holes formed at right
angles to the above mentioned hollow, and at right angles to each other, and pass
through the greatest circumference of the top. At the bottom of the hollow before
mentioned is a sunken socket into which the lower end of a whistle is forced, the
upper end of the whistle being level with the upper part of the top. A ring of any
suitable substance is fastened round the upper part of the whistle, and fits tightly
into the neck of the above mentioned hollow, holding the whistle firmly in its place
in the centre of the top, and prevents the air passing into the top except through
the whistle. The whistle can be made of metal or any other suitable material, and
is preferably of a tubular shane
DESCRIPTION OF THE DRAWINGS.
This invention will be clearly understood by referring to the figures and letters
0 on the accompanying sheet of drawings in which
Figure 1. is a vertical section of the top, with the whistle and ring placed
therein.
Figure 2. is the same with the whistle and ring removed.
Figure 3. is a plan of the ring or collar.

page_text: Figure 4. is a vertical section of the whistle.
Like letters refer to corresponding parts in the four figures.
A is the body of an ordinary spiked top, which may be made of any suitable material.
B is a hollow or hole formed in the centre of the upper part of the top, and passes
a short distance down into the top. The horizontal holes C, pass through the
greatest circumference of the top, and form passages in connection with the hole or
hollow B. D is the sunken socket into which is forced the lower end of the whistle.
E is the whistle, shown in Figures 1 and 4. F is a ring or collar which is placed
round the upper end of the whistle, and fits tightly into the neck of the above
mentioned hole or hollow. G is the spike on which the top revolves.
To spin the top and produce a musical sound, a string is wound round it in the
usual way, and thrown sharply to the ground. As it rapidly revolves the holes C
throw out the air from the centre of the top, causing a partial vacuum, which draws
the air through the whistle producing a musical sound.
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,
1st. A musical top formed by the whistle E being placed therein as described,
with suitable holes for the circulation of the air.
2nd. The ring or collar F which is placed round the upper part of the whistle E,
and fits tightly into the neck of the hollow B.
3rd. The sunken socket in which the lower end of the whistle is placed. All
herein described and for the purpose stated.
Dated this 7th day of January 1893.
