PROVISIONAL SPECIFICATION.
Improvements in Tops.
I, GEORG FISCHER of Nuremberg in the Kingdom of Bavaria, German Empire,
manufacturer do hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in spinning tops and is such that the top
whilst spinning is caused to strike one or more gongs in rotation.
In order to make my invention more clear, I refer to the accompanying drawings,
in which similar letters denote similar parts throughout the several views.
Fig. 1 is a vertical section through my improved top.
Fig. 2 is a sectional plan on line a ẞ in fig. 1.
Fig. 3 shows a section of a modification of the top.
i is the spindle of the top, to which the roller m round which the string is wound, is
firmly fixed, and also the body h of the top. The spindle i has further a projection ¹
and has its bearings in the top and bottom screws d and d', which are adjustable in the
frame a.
The frame a consists of two or four wires a a fixed at the top in plate 6 and at the
bottom in 61 and has the two wings e and e¹. It has further, fixed to it at j'and 'the
rods g and g', to which are fixed the hammers r and ¹ for the two gongs g² g². The
gongs are fixed to the lower screw d¹ and held in place by nut y. A card or other
disc having various colours may be laid on to the body of the top, or having a ring
of figures round its circumference and a pointer ' fixed to frame a when the top may
also be used as a teetotum.
The top works in the following manner :
It is wound up and rotated in the usual manner and on being set in motion, the
frame a on account of its wings e e¹ will not rotate so quickly as the spindle i, and
body of the top h. In consequence of this difference in the speed of the top and top
frame, the projection will be continually brought against the ends of rods g and g¹
successively, will push the same back, which then on account of their elasticity will
spring forwards on being released and strike the gongs...
Of course I can, as shown in fig. 3, reverse the principle and make the frame a¹ of
the top carrying the hammers G G₁ of the gongs, revolve more quickly than the
spindle I (fig. 3) in which case the ends of the hammers are brought against the
projection on the spindle, the spindle having wings E E preventing it from revolving at
the same speed as the frame a¹. The frame a¹ inust have holes oo to allow the air to
act on the wings E E. The string is in this case wound round the upper part M of
the frame a¹ and the handle N may be removed when the top has been set up. The
frame a¹ has ring a² in order to give it weight enough to revolve well..

COMPLETE SPECIFICATION.
Improvements in Tops.
I, GEORG FISCHER, manufacturer of Nuremberg, in the Kingdom of Barvaria,
German Empire, do bereby 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 :-
My invention relates to an Improvement in spinning tops, and is such, that the top
whilst spinning is caused to strike one or more gongs in rotation.
In order to make my invention more clear, refer to the drawings sent in with

page_text: provisional Specification, and in which similar letters denote similar parts throughout
the several views.
Fig. 1 is a vertical section through my improved top.
Fig. 2 is a sectional plan on line a ẞ in Fig. 1.
Fig. 3 is a section of a modification of the top.
i is the spindle of the top, to which the roller m round which the string is wound, is
firmly fixed, and also the body / of the top.
The spindle has further a projection
and has its bearings in the top and bottom
screws d and d¹, which are adjustable in the frame.
The frame a consists of two or four wires a a fixed at the top in plate b and at the
bottom in 6, and has the two wings e and e¹. It has further fixed to it at j and 1.
the rods g and g', to which are fixed the hammers and ¹ for the two gongs g² 9³.
The gongs are fixed to the lower screw d¹ and held in place by nut y.
A card or
other diser having various colours, may be laid on to the body of the top or having a
ring of figures round its circumference and a pointer fixed to frame a when the top
may also be used as a teetotum.
The top works in the following manner:
It is wound up and rotated in the usual manner and on being set in motion, the
frame a on account of its wings e e¹ will not rotate so quickly as the spindle i, and
body of the top h. In consequence of this difference in the speed of the top and top
fraine, the projection will be continually brought against the ends of rods g and gl
successively, will push the same back, which then on account of their elasticity will
spring forwards on being released and strike the gongs.
Of course I can, as shown in Fig. 3, reverse the principle and make the frame or
body a of the top carrying the hammers of the gongs, revolve more quickly than the
spindle I (Fig. 3) in which case the ends of the hammers are brought against the
projection on the spindle, the spindle having wings E E preventing it from revolving
at the same speed as the body a¹. The body a' must have holes o o to allow the air to
act on the wings E E. The string is in this case wound round the upper part M of
the frame a¹ and the handle N may be removed when the top has been set up. The
frame a¹ has ring a² in order to give it weight enough to revolve well.
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 :
In tops:
1. A top having one or more gongs adapted to strike alternately on rotating
the top.
2. The combination of one or more gongs attached in a frame a in which the top
spindle runs, the frame having further hammers elastically attached to it by rods g g²,
having one of their ends attached to the frame and the other projecting towards the top
spindle and adapted to be operated by a projection on said spindle, said frame a having
retarding wings ee causing it to revolve more slowly than top spindle i, whereby
projection on the latter is brought against hammer wires thus striking the gongs
alternately, in the manner substantially as described.
3. A top having a body provided with holes and inside said body a spindle running
independently of the body and provided with retarding wings and having a projection
adapted to strike the gong hammers attached to the body owing to the difference in
speeds of said spindle and body, in the manner described.
4. A top consisting of the combination of body a¹ having holes o o, ring a²,
gongs g²² and hammers and handle N, spindle I having retarding wings E E,
and projection i, in the manner substantially as described.
