My present invention relates to an improved method of making shuttlecocks or aerial missiles employed in games, such as badminton, in which the shuttlecock is passed or tossed back and Figure 4 is a sectional view of Figure 3, taken f along line 4 4.

inserted through the flat portion of the upper cover-section i8, and into the head for a suitable distance to anchor the feathers. Due to the resiliency of the material composing the head, the inserted ends of the shafts are grasped or clasped Y 5 tenaciously by the material and the feathers are firmly held in place.

To hold the individual feathers against spreading, and to preserve the uniform and symmetrical shape ofthe tail of the shuttlecock, a cord 2l is twisted and intertwined about the adjoining feathers, and this cord, which is located just below the webs of the feathers, extends entirely around the tail in contact with the shafts', to hold the feathers in their proper spaced relation.

` In the method of manufacture of my shuttlecock the steps are as follows:-The cork is first fashioned to form the head Ill of the shuttlecock and then the cover-sections i6 and i8 are glued or otherwise fastened to the head. The annular band I9 is then permanently attached covering Y the joint between the two cover-sections. The shafts 20 of the annular series of feathers are then inserted through the cover andinto the head in the manner described and the shafts are secured in xed relation by means of the twisted f cord 24.

Due to the nature of Vthe materials thus employed in Vthe manufacture of the shuttlecocks, as shown in Figure 2, they may vary from 10 to 15 grains in weight and therefore thefshuttlecocks cannot with precision be accurately standardized as to weight.

In the method of my invention, I now weigh veach assembled shuttlecock and determine the variations in weight between them and a predetermined'standard. We may assume in this instance that thepredetermined standard is, say, 77ers. 'Ihen the weight to be added must be equal to the difference between the weight of the 40 completed birds, and the predetermined standard of weight. Assuming that the shuttiecocks have been completed, and all under the weight stand- Y Yarci, weighing 68, 70, and 71 grs. respectively, then pellets or weightsof 9, 7, and 6 grs. respectively y must be added to bring the individual weights to' exactly 77 grs.

. A suitable tool is then inserted through the cover i3 and into the center of thev head, and then withdrawn, to form a passage 25, to facilitate the insertion of a weight.

A weight such as a pellet of lead 2l, equal to the difference'in weight between the assembled shuttlecock vand the predetermined standard as stated above is then inserted through the flat vtop of the cover i0 and into'the passage 25. As shown in the drawing, Figure 3, the pellet is inserted in the head well below the cover il, in order that the passage may be closed by the resiliency of the cork.

o It will be apparent that the pellet or weight will be retained in the desired position through the rough usage of `a game.

Obviously pellets of differentweightsare used in the respective shuttlecocksr accordingY to the variance of their weights. Y

The disk, as 2'l, is then glued or otherwise attached to the head entirely surrounding and covering the openingcaused by the insertion of the pellet.

The shuttlecocks are now completed and all of them manufactured and assembled according to my method will be of the exactsame weight thus j insuring a perfectset of playing missiles which will respond identically to the players stroke.

While I have shown and described the weightas being of spherical shape, it will be'understood that a weight of any desirable and suitable shape may i be employed. l
