PROVISIONAL SPECIFICATION.
Improvements in or relating to Shuttlecocks.
I, CALEB JOSIAH ALLEN, of Chadstone, Dam Street, Lichfield, in the County
of Staffordshire, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or relating to shuttlecocks, its object
being to cause the same to answer to the blows of the bat more readily and to take
flight on the slightest application of the same.
According to this invention I form the base or lower part of the shuttlecock
wholly or partly of india-rubber or other suitable elastic material and provide the
same with a hermetically sealed central cavity or air
space.
Where for reasons of economy india-rubber or other suitable elastic material
cannot be employed for the construction of the whole of this part of the shuttlecock,
I employ wood, cork, or other suitable light material for the upper part of the same
into which the feathers are inserted, the lower part surrounding the herein before
mentioned cavity being in every case formed of the elastic material such as india-
rubber, or the like.
It will be seen that this hollow elastic base forms and acts, as it were, as a
pneumatic cushion which greatly increases the rebound of the toy, thereby giving a
maximum of pleasure for a minimum of exertion.

COMPLETE SPECIFICATION.
Improvements in or relating to Shuttlecocks.
I, CALEB JOSIAH ALLEN, of Chadstone, Dain Street, Lichfield, in the County
of Staffordshire, Sculptor, 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 shuttlecocks, its object
being to cause the same to answer to the blows of the bat more readily and to take
flight on the slightest application of the same.
According to this invention I form the base or lower part of the shuttlecock
wholly or partly of india rubber or other suitable elastic material and provide the
same with a hermetically sealed central cavity or air space.
Where for reasons of economy india-rubber or other suitable elastic material
cannot be employed for the construction of the whole of this part of the shuttlecock,
I employ wood, cork, or other suitable light material for the upper part of the same
into which the feathers are inserted, the lower part surrounding the herein before
mentioned cavity being in every case formed of the elastic material such as india-
rubber, or the like.
It will be seen, that this hollow elastic base forms, and acts, as it were, as a
pneumatic cushion which greatly increases the rebound of the toy, thereby giving a
maximum of pleasure for a minimum of exertion. Besides this, vibration, and con-
sequent loss of feathers, is prevented.
And in order that my invention may be more readily understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
sheet of drawings, Figure 1 of which shows a shuttlecock constructed according to

page_text: this invention in which the base a is composed wholly of india-rubber or other
suitable elastic material having a hermetically sealed central cavity or air space h.
The feathers c are inserted in a number of openings provided for their reception in
the upper part of the base a.
cup
As shewn in Figure 2 the feathers are inserted in openings in a dise of wood
or other suitable material inserted in the open end of a thimble or cup of india-
rubber or other suitable elastic material a so as to enclose the hermetically sealed
air space or cavity in the interior of the same. As shewn in the drawing the
or thimble a is secured to the disc d by means of a wire or other band e which
draws the upper edges of the cup into a groove formed upon the periphery of the
disc d. If preferred the parts may be secured to one another by means of a suitable
cement; in some cases the cement may be employed in addition to the wire shewn
at Figure 2.
In some cases I insert a small bell, whistle or "jingle" or other suitable article
for the purpose of forming a musical attachment. Such device may be suspended
from the underside of the disc d, inserted therein or laid inside the cavity of the
cup a as the case may be.
Though I have only illustrated two methods of carrying my invention into effect
it is obvious that it may be modified in various ways without departing from the
principle of the same.
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
The formation of the base or lower part of a shuttlecock wholly, or partly, of any
suitable elastic material enclosing a hermetically scaled air space or cavity substan-
tially as and for the purpose herein set forth and described and illustrated by the
accompanying drawings.
