M. CARO BALL FOR PLAYING GAMES Filed Jan. l0, 1934 2 Sheets-Shea?l 2 1111114111114Inv/111111111 Patented Aug. 27, 1935 PATENT OFFICE BALL FOR PLAYING GAMES Martin Caro, Brussels, Belgium Application January 10, 1934, Serial No. 706,102 In Belgium January 12, 1933 This invention relates to balls for playing games such as football or the like and comprises a casing having an opening for the insertion of a valved bladder and an infiation opening diametrically positioned relative to the first opening.

The invention also provides that the said bladder be removably connected to the casing by means of its neck.

According to the invention, the connection between the bladder and casing is obtained by means of an arrow-shaped member formed of iiexible material. This arrow-shaped member is united with the portion of the casing provided with the ination opening and the sharp ends of this arrow-shaped member are adapted to be inserted through holes of a member united with the neck of the bladder.

According to another form of the invention, the connection between the bladder and casing is effected by means of a plate, for example made of steel, united to the neck of the bladder and inserted in a recess provided in the portion of the casing having the inflation opening.

The annexed drawings show, by way of example and in a non-limiting manner, several embodiments of the invention:

Figure 1 is a fragmentary section through the ball, according to the invention.

Fig. 2 is a fragmentary plan view showing the details of the connection between the bladder and the casing.

Fig. 3 is a fragmentary perspective view of the bladder and the connecting device.

Fig. 4 is a section through the ball.

Fig. 5 is a plan View of the closing flap of the ball.

Fig. 6 is a fragmentary sectional view of a modified form of the invention.

Figs. 7 and 8 are fragmentary plan and sectional views of another modication of the ball, according to the invention.

According to Figs. 1 and 2, the valved bladder 2 is inserted, neck forward, into the casing 3 through a hole 4, the dimensions of which are large enough to avoid deformation and easily allow the insertion and withdrawal of the bladder. The neck of the said bladder is provided at its upper part with a piece 5, made of indiarubber, upon which a metallic plate 6, for example of steel, is attached by means of rivets.

When the bladder is pushed into the casing, the said plate 6 is inserted into a recess I positioned diametrically opposite the hole 4 in the portion 8 of the casing. This recess 'I is obtained by the cooperation of the portion 8 of the CaS- ing and a piece of leather 9 sewed thereto. The said piece of leather is provided with a hole I having a shape similar to that of the metallic plate and is positioned in front of another hole II provided in the portion 8 of the casing for the inflation of the bladder. The plate 8 is inserted through hole Ill into the recess and is then turned perpendicularly to the first position, in order to take the position illustrated in Fig. 2. Since plate B is made of elastic steel, it takes the shape of the casing.

According to Fig. 6, a rigid, short and threaded pipe I6, made of Bakelite for instance, is united to the portion 8 of the casing and positioned axially of the hole II. In order to obtain the connection between the bladder 2 and the casing, the said pipe is screwed into hole Il of the neck of the bladder. This latter hole is internally threaded and may be metallically lined. The screwing of the pipe I6 into the hole of the neck may be effected from the exterior of the ball.

When the ball is iniiated a stopper I 8, the head of which is hidden under a piece of leather, is screwed into the pipe I6 until its leather comes into the plane of the leather of the casing. The screwing of said stopper is obtained by means of a tool which enters into holes such as I9 provided into the head of the said stopper. In proportion as the said bladder inates, the casing is automatically closed without tools by means of the flap I 3 being of leather (Figs. 4 and 5) and which is sewed in the proximity of the hole 4. This fiap is provided upon its interior side with a plate I4, made of mica, covered with a piece of leather sewed to the said flap. The dimensions of this plate I4 are greater than those of the hole 4 and prevent the deformation of the ball under the pressure of the inflated bladder.

The stitching providing the connection between the piece 9 and the casing and equally the stitching in the closing flap I3 are similar to the stitching of an ordinary ball. Besides, due tothe fact that the recess 'I and the hole 4 are diametrically positioned, the ball is perfectly balanced.

According to Figs. 7 and 8, a kind of arrow-like member I8, made of flexible material and provided with a hole I9, is sewed to the portion 8 of the casing, so that its hole is axially aligned with the hole I I of the said casing. The neck of the bladder is provided at its upper part with a piece 2 I, made of exible material such as leather, provided with two holes 22 through which the sharp ends 23 of the arrow-like member I8 are inserted (see Fig. 8). VBy this means, the bladder is connected tothe portion 8 of the casing and is maintained in this position by means of barbs 24 of the arrow i3, which engage against the lower side of the piece 2E. When this connection is obtained, the bladder is iniiated.

What I claim is:-

1. A ball comprising a bladder, a casing provided with openings for the introduction of the bladder and for ination of the bladder, a piece of flexible non-metallic material axed to the interior of the casing adjacent the inflation opening and provided with two tongues, and a collar of iieXible non-metallic material afxed to the bladder and provided with apertures for the reception of said tongues for connecting the bladder to the casing.

2. A ball comprising a bladder, a casing provided with openings for the introduction of the bladder and for inflation of the bladder, a collar of flexible non-metallic material attached to the bladder and provided with apertures, a piece of exible non-metallic material attached to the interior of the casing adjacent the inflation opening and provided with arrowhead like tongues adapted to enter the apertures in the collar attached to the bladder, and barbs on said tongues adapted after being passed through the apertures in the collar to engage one face of the collar to avoid accidental removal of the tongues from said apertures.

3. A ball comprising a bladder, an outer casing provided with two diametrcally opposed openings, one of said openings serving for the introduction of the bladder and the other opening serving for inflation of the bladder, a flap positioned on the' interior of the casing and attached thereto adjacent the opening for the introduction of the bladder in the casing, a plate of ilexible semi-rigid material of dimension greater than that of the opening for the introduction of the bladder, and means for securing said plate to the internal face of the ap for closing the bladder 20 introducing opening.
