SHUTTLECOCK Theodore Amphlett, Los Angeles, `Calif., assignorto A. G. Spalding & Bros. Ine., Chicopee, Mass., a corporation of Massachusetts Application March 20, 1947, Serial No. 736,007

The present invention relates to shuttlecocks for use in connection with the game of badminton or the like and particularly to a shuttlecock having means for removably and replace-1 According t the present invention the shuttlecock is provided with means for detaohably connecting the vane to the body so that it remains in position throughout normal use ofthe shuttlecock but which permits the vane to be removed and replaced when desired.

In the present preferred form of the invention this is accomplished by providing the shuttlecock body with a socket to receive the end of the vane and a guided plug for pinching they vane against the side wall of the socket to hold itin place.. The plug is held in place, against dislodgement during normal use, by friction and without the usevof adhesives or other permanent fastening means so that it may readily be removed and replaced whenever it is desired to change or replace the vane.

Preferably a portion of the surface of the socket is provided with a taper corresponding to the taper of the conical vane and a guide post. The n plug is slidably mounted on the guide post and is provided with a cooperating surface for clamping the end of the vane against said tapered portion.

The vane attaching means of the present invention is so constructed and arranged that it may or may not alter the weight, distribution or playing characteristics oi the shuttlecock as required.

Other features and advantages will be apparent from the specication and claims when considered in connection with the drawings in which:

Figure l shows a side elevation of a shuttlecock of the present invention.

Fig.V 2 is a longitudinal sectional view of on form of the invention.

Fig. 3 is an exploded view of Fig. 2.

Fig. 4 is a longitudinal sectional View partly broken away of another form of the invention.

Fig. 5 is a detailed section through the vane.

As shown in the drawings the bodyV l0 which Claims. (Cl. 273-406) may be made of cork or other suitable body material is provided at one end with a semispherical surface Il which is usually contacted by the racket or other implement used during the playing of the game of badminton or other similar games. The outer surface of the body may be covered With a protecting cover i2 of kid, rubber, lacquer or other protective material and the upper edge covered by a band I3 adhesively secured to or shrunk into place asis well known in the art. This band not only iinishes the cover but also reinforces the wall at the upper end of the body as will be described.

A vane M is connected to the body for the purpose of steadying the shuttlecock in flight. While the vane may be made up of quills or feathers, conically arranged, in the illustrated form of the invention, the vane is a cone formed from layers of stiflened. open mesh porous fabric lila with a layer of less porous material, such as paper or the like material ltb disposed about the apex of the cone between the layers Ma as shown in Figs. 3 and 5, and extending along the sides and shaped as required to vary the porosity of the vane and produce the desired ight characteristics of the shuttlecook.

The means for mounting the vane to the body according to the present invention comprises an annular Wall l5 preferably integral with the body andextending upwardly from said other end of the body producing a vane receiving socket i6 in the end thereof..

Acenter post I1 projects axially from the body within the socket and transforms the socket into an annular recess. While the center post may be of various materials, in the herein disclosed form 'of the invention it is made integral with the cork body.

The Walls of the socket are preferably tapered at I8 adjacent the outer end as shown in Fig. 2,`

so thatvthey have the same taper as the vane and will engage and support the end of the vane when the latter is inserted in the socket.

According to the present invention the vane .is detaohably clamped and held in the socket by means of a clamping plug I9 having a tapered surface ISa and a bore iilb extending therein to receive the center post which guides and supports the same. The clamping plug is preferably made of a resilient and slightly compressible material. rlhe presently preferred plug is made of cork, the same material as that of the body, in which case the weight and balance of the body is not substantially altered, with the plug in place, from a body of the same shape. However, the plug may be of lighter or heavier material to vary the center of gravity of the body if desired.

When the annular plug is pushed into the recess it pinches the vane against the tapered wall, and since it is guided and supported by the post and backed up by the post, it frictionally grips the v-ane and holds it in place during normal use of the shuttlecock. Should there be any tendency of the wall I5 to flex outwardly under pressure of the plug it will be resisted by the band I3.

If desired, the inner end of the recess may be made cylindrical as shown at in Fig. 3. This will enhance the gripping of the vane, for, as the plug is pushed in, it causes a slight bend at the vane at the joint between the cylindrical and tapered portions because the cylindrical Yvvalldoes not back up the vane and permits the vane to yield under pressure of the tapered plug. lThis effectively binds the vane to the joint between the two surfaces.

If the bore I'Sb extends through the plug, so Ias to transform the plug into an annulus, the upper end may be closed by a cover '-21 -of liber, paper or the like secured to and extending over the end of the plug.

In some instances it may be desired to increase the frictional hold on the vane by inserting friction means in the socket. While the friction means may take many forms, it is herein illustrated as comprising light sheet metal ngers 22 anchored to the body, the ngers having barbs or the like 23 projecting from their faces and against which the vane is forced by the plug as it is moved to clamping position.

When the vane becomes ydam-aged or it is desired to remove and replace 'the same it is merely necessary to remove the plug by overcoming the friction grip of the plug. One way of accomplishing this is by rocking the vane sideways and walking the plug out of the socket similar to the removal of a cork from ia bottle neck.

Thus it will be seen that the vane is Suiciently held in position during normal use by the vane and the plug may be forcibly removed, should it be desired to remove the same, without destroying the body of the shuttlecock or the plug. Y

Variations and modiiications may be made within the scope of this invention and portions of the improvements maybe used without others.
