3 Claims.

The object of this invention is to make a new and improved form of shuttlecock for use in the game of badminton, or battledore and shuttlecock.

Another object of the invention is to provide in the shuttlecock a reservoir of oil or grease which can be taken up by the feathers, with the result that the feathers will be kept in a flexible or elastic condition, rather than a stiff, brittle condition. This makes it possible to use ordinary goose feathers in the shuttlecock and give them a much longer life than they would otherwise ordinarily have.

Another object of the invention is to provide the base of the shuttlecock with a groove, in which is wrapped a wick suitably impregnated with oil, such as olive oil, that will be readily absorbed by the quills of the feathers and will travel through the feathers by capillary attraction.

Another object of the invention is to increase the weight of the cork base of the shuttlecock by the oil, so that any other loading of the shuttlecock would be unnecessary.

Another object is to make the feathers moistureproof by adding oil thereto in the manner above described.

These and other objects of the invention will be illustrated in the drawing, described in the specification and pointed out in the claims at the end thereof.

In the drawing:

Figure 1 is a side elevation of my improved shuttlecock.

Figure 2 is a vertical section through the shuttlecock on the line 2(B-2ZB of Figure l, the shuttlecock being shown on a large scale.

Figure 3 is a side elevation of the cork base of the shuttlecock shown in Figure 1.

Figure 4 is a vertical section through the cork base of the shuttlecock, showing a different type of construction.

Figure 5 is a top plan view of the plug shown in Figure 4.

In the drawing like reference numerals indicate like parts.

In the drawing reference numeral I indicates the cork base of my improved shuttlecock. This base is preferably made of a single piece of cork, which is rounded on the end to a ball or spherical shape as indicated at 2. The upper portion 3 is preferably cylindrical in shape. Between the lower portion 2 and the upper portion 3, the base is cut away to form a groove 4. Into this groove is wound a piece of cotton wicking 5, which is long enough to go twice around the groove and is thick enough to substantially fill it. The weight of the wick used in the groove is substantially equal to the amount of cork that is displaced thereby. The weight of the wick is increased by adding thereto about eight to ten 5 grains of oil, preferably olive oil or any oil that will be drawn through the quills and feathers by capillary attraction and make them flexible, or reduce their brittleness.

This cork base is perforated with suitable openings, in which are inserted the quills 6 of feathers 'I. These quills are long enough so that the ends of them are embedded in the inner layer of the oiled wicking. Before the quills are inserted, the top of the cork base is covered with a layer of leather 8, through which the quills are inserted.

On the outside of the cork base is applied a layer of material, such as kid leather, indicated by the reference numeral 9. This covers the spherical and cylindrical surface of the base completely and conceals the groove 4 and the packing therein. Over this leather covering is placed a tape l0, which is preferably of a different color from the cover 9 and gives to the base an ornamental appearance.

With the quills embedded in the cotton wicking, the oil in the wicking is absorbed by the quills and travels along the quills and impregnates the quills and the feathers, making the feathers and quills less brittle and more elastic, in consequence of which they do not tend to split up or break so quickly.

Furthermore, the extra weight that is given to the base of the shuttlecock by the presence of the oil makes it unnecessary to add any other weight or load to the base, such as has heretofore been customary.

It also makes the feathers moistureproof, so that they remain of uniform weight, and their weight does not vary with the humidity of the air.

In Figure 4 I have shown another type of construction of the shuttlecock in which the cork base I5 is not cut away on the side with a groove 4, such as is shown in Figure 2, but is cut away on 45 the top with a cone-shaped socket indicated by the reference numeral Hi. In the socket is fitted a cone-shaped plug or cork H, the sides of which are channeled, as indicated at l8, l8. Into each of these channels is placed the quills of the goose feathers, and this plug with the quills of the goose feathers nested in the channels is inserted in the socket, and completely fills the socket except at the bottom, where a disc-shaped opening I9 is left in which the wicking, impregnated with oil, 55

is contained. This wicking is in contact with the ends of the quills, so that the oil is absorbed therefrom and will travel along the quills with the same result as above described.

The walls of the channel 4, the walls of the socket l6 and of the plug I! are preferably coated so that they will not absorb the oil. This will make all of the oil available to the feathers and quills only, where it is needed. The plug I! will be cemented or fastened in any suitable manner in the socket, so as to be securely held therein and hold the feathers in place.

I claim:

1. A shuttlecock having a base, feathers having quills inserted into said base, a supply of oil held in the base in contact with the quills of said feathers, from which the oil can travel through the quills and feathers.

2. A shuttlecock having a base, feathers having quills inserted into said base, an annular groove around said base into which the quills of the feathers extend, wicking impregnated with oil held in said groove in Contact with the quills of said feathers.

3. A shuttlecock having a base, feathers having quills inserted in said base, a recess in said base, a supply of oil held in said recess in contact with the quills of said feathers, said oil being adapted to be absorbed by the quills and feathers.
