An Improved Construction of Musical Hoop.
PETER PERRY, 8 Blacklion Lane Hammersmith County of Middlesex, Engineer,
do hereby declare the nature of this invention to be as follows:-
This Invention has for its object the adaptation to childrens hoops of musical
appliances such as gingles reeds or the like which will emit musical sounds when
acted upon by the revolving motion of the hoop.
When carrying out this Invention in its simplest form I attach either to the inner
surface of the hoop or io rods passing from one side of the hoop to the other gingles
or metal dises which as the hoop revolves will vibrate and emit musical sounds bu
when adapting my improvements to that class of childs hoop which is provided with
a forked handle I cause the hoop to revolve on a fixed axle, and to the fixed hub of
the wheel I fix expanding spring reed boxes so placed that as the wheels revolve, wires
placed across the inner surface of the wheel or hoop will in succession act upon the
said reed boxes in a manner which will cause them to emit musical and harmonious
sounds.

An Improved Construction of Musical Hoop.
I, PETER PERRY of S Black Lion Lane, Hammersmith in the county of Middlesex,
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 :-
This invention has for its object the adaption to childrens' hoops of musical
appliances, such as gingles, reeds, or the like, which will emit musical sounds when
acted upon by the revolving motion of the hoop. When carrying out this invention
in its simplest form, I attach either to the inner surface of the hoop, or to rods passing
from one side of the hoop to the other, gingles, or metal dises, which as the hoop
revolves will vibrate, and emit musical sounds, but when adapting my improvements
to that class of child's hoop, which is provided with a forked handle, I cause the hoop
to revolve on a fixed axle, and to the said axle I fix expanding spring reed-boxes, so
placed that as the wheels revolve, a wire, or wires, placed across the inner surface of
the wheel or hoop will in succession act upon the said reed-boxes in a manner which
will cause them to emit a succession of musical sounds.
In the accompanying sheet of drawings, Fig. 1 represents a side elevation of a
musical hoop having a forked handle and fitted with reed boxes in accordance with
my invention, and Fig. 2 is a side elevation of a similar hoop of somewhat modified
arrangement.
Similar letters of reference refer to similar parts in both figures.
In Fig. 1A is the rim of the hoop provided with eight wire spokes B, four of the
said spokes being fixed into a hub C on one side and the alternate four spokes into a
similar hub on the other side. I do not however confine myself to the use of any
particular number of spokes.
The hubs and the wheel rotate upon an axle D fixed in the end of the forked handle E.
A reed-hox F is fixed on the axle D between the hubs and is provided with four
bellows H, H, H2, H3. There are eight reeds, giving different notes, in the box F,
two to each bellows, so arranged that the closing of a bellows will sound one reed
while the opening will sound the other. The bellows are closed in succession by the
bent wire J fixed in the rim, as the hoop is rotated, and are opened by suitable springs
fixed within them. The dotted lines shew a bellows fully compressed by the wire J.
A hoop of this construction can only be rotated in the direction of the arrow, as in
attempting to rotate in the opposite direction the wire J will come in contact with
the next bellows and lock the wheel.
In the modified arrangement shewn in Fig. 2 the boop can be rotated in either
direction. The general construction is the same as that of Fig. 1 with the exception
that in place of the wire J an eccentric K is fixed on the axle D on each side of the
reed-box F, a hoop I, with an arm M, pivotted to an eye N works the bellows H both
in and out, and a hoop L' with an arm M' works the bellows H', while similar hoops
and arms on the other eccentric work the bellows H2 H³. In this case no internal

page_text: spring is required to open the bellows. I should be explained that in Fig. 2 part of
the handle is broken away and the spokes and hub on one side removed in order to
shew the eccentric clearly. Although I have shewn and described the hoops as
provided with four sets of bellows and eight reeds, it is obvious that I may have a
smaller or larger number as desired, and that the rotation of the hoop may be caused
to play a tune, or to sound the notes in any other desired succession.
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). A child's hoop emitting musical sounds when rotated, constructed with a fixed
reed-box and bellows, actuated by a wire or wires fixed within the rim of the hoop,
substantially as herein described and shewn with reference to fig. 1 of the accompany-
ing drawings.
(2). A child's hoop emitting musical sounds when rotated in either direction,
constructed with a fixed reed-box and bellows, actuated by eccentrics on the axle,
substantially as herein described and shewn with reference to Fig. 2 of the accom-
panying drawings.
