' I. I. TUBBS INFLATED BALL Get. 1, 1929.

Filed Sept. 22, 1924 "Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE IRA m1. TUIBBS, on summon, WISCONSIN, ASSIGNOR on ONE-HALF T GEORGE n. MILLER, 0F MENOMINEE, WISCONSIN INFLATED BALL Application filed September 22, 1924. 'Serial No. 739,127.

My invention relates to inflatable playing or sport balls of the type provided with a cover of leather or other flexible material j which is inflatable and defiatable through the medium of a bladder positioned within the cover. Balls of this type may be used for playing basket ball, football, water polo and many other games, and may also be used as punching bags. The invention isconcerned with improvements appertaining to the bladder inflation instrumentalities of such balls.

An object of the invention is to provide improved means for mounting the bladder with-- in the cover with the air inlet of the bladder communicating with an opening in the cover so that the bladder can be inflated or air letout .or more air applied,all from the outside of the ball without it being necessary to interfere in any way with the opening through which the bladder is inserted within the cover. I

Another object of this invention is to provide a ball which will be regular in form and elasticity so that pressure applied to any part will produce exactly the same reaction.

The present invention provides a ball so constructed and arranged that its bladder may be inflated by a suitable pump such as a bicycle p'ump applied to and through the ball cover at a point preferably spaced from the bladder-insertion opening of the cover; the bladder being provided with a stem through which it is inflated, this stem being readily attachable to and detachable from a covercarried holding-device when the bladder is deflated, but being securely retained in cooperating relationship with the holding-device when the bladder is inflated. The holding-device, its construction, its relationship to the cover, and its relationship to and cooperation with the stem of the bladder are salient features of the present invention.

The ball shown in the accompanying drawings also includes a novel lacing for closing the bladder-insertion opening of the cover, a lacing which may or may not be employed in balls provided with the improvements herein claimed. Such lacing is described and claimed in my Patent No. 1,664,336, dated March 27, 1928.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of, a ball look ing at the side having the inlet opening formed therein.

Figure 2' is a sectional view taken along the line 2-2 of Fig 1.

Figure 3 is a view similar to Fig. 1 showing the ball with the bladder deflated and the inlet opening spread for insertion or removal of such bladder. i

Figure 4 is a transverse sectional view taken alongthe line 4-4 of Fig. 3.

Figure 5 is a fragmentary sectional view taken along the line 55 of Fig. 1 with the bladder in place but not inflated.

My improved playing ball is provided with a cover 1 formed of leather or any other suitable material and if desired formed in a number of sections stitched together after the manner usually employed in constructing basket balls, punching bags, foot "balls or other balls of similar construction. This cover is' provided with a bladder insertion opening 2 in the form of an elongated slit which when in the closed position will appear as shown in Fig. 1, but which may be spread to an open position as shown in Fig. 3. A small aperture 3 is formed in the cover to one side of the opening-2 and registers with the internally threaded neck 4 of the socket plate 5 at the inner face of the cover. This plate 5 is provided with a covering 6 formed of any suitablamaterial such as thin leather or a suitable fabric, the covering 6 serving to prevent chafing of a bladderplaced within the cover. A cushion 5' preferably. of rubber, may be inserted between the socket plate and the cover. The purpose of this cushion is to absorb the jar when the part of the cover directly at the outside of the socket plate comes in contact with the floor or other surface. Were the leather cover of the ball directly in contact with the socket plate, there would be more of a shock and a greater sound and the ball would not bounce as well.- The bladder 7 is inserted within the cover through the ladder insertion Opening 2 and is provided with a threaded valve stem 8 which may be screwed up into the neck4 as shown in Fig. 5. The detail of the interior construction of the valved stem is not shown since this is similar to, the construction of a valve-controlled inlet used in connection with an inner tube of a tire.

I being Flaps 9 have been shown secured to the inner side of the cover 1 atopposite edges of the opening 2 and other flaps 9' are secured to said inner side of the cover in outwardly spaced relation with said flaps 9, all of the flaps extending toward the openin 2. Any

or all of these flaps may be formed y folding a strip of leatheror the like upon itself and stitching its edges to the cover 1, the flaps 9 shown of this form. while the flaps 9 are illustrated merely in the form of strips stitched at one edge of the cover. Strips or lacings 10. extend across the opening 2 and are slidably connected to the flaps 9 and 9". These strips or lacin s are of such length that when the bladder is inflated, the portions of the cover upon opposite sides of the opening will be; drawn toward each other and into edge contacts as shown in Figs. 1 and 2 to entirely close the opening 2 with the flaps and strips positioned in close contact with the inner face of the cover. Any irregularity in the length of the strips or lacings 10 will be equalized by sliding at the flap connection. In the construction shown,

the flaps 9 and 9' are formed with spaced eyelets and there are two lacingsfllO inter lacedwith these eyelets, each lacing connecting the flap 9 at one edge of the opening 2, with the flap 9' at the other edge of said opening.

When the ball is to be inflated, the threaded can be employed to inflate the bladder. When the bladder-is inflated, it is expanded and as it expands it will distend the cover and 'through engagement with the flaps 9' cause the strips orlacings 10vto be drawn upon, which in turn will draw upon the flaps 9 and draw-the cover to entirely close the opening 2. It will thus be seenthat the greater the air pressure, the greater will be the pull applied to the strips or lacings 10 and the tighter the openin will be held-in a closed position. s It will urther benoted that the covering 6 will prevent chafing vwhich might tend to wear the bladder and also that the air can be readily let out or the pressure regarded as a composite holding-device secured to the inner face of the cover for cooperation with the threaded stem of the bladden As shown in the drawings, this composite holding-device is of substantial thickness at its central portion. where it receives the bladder-stem 8; the thickness of the holdingdevice decreasing from its central portion toward its margins. It is desirable that the holding-device be of substantial thickness at its central portion so that the bladder stem may have adequate threaded engagement with the plate 5, while terminating a substantial distance short of the exterior of the ball cover. By having the thickness of the holding-device decrease from its central portion to its margins, I prevent undue'chafing of those parts of the bladder which must yield inwardly to accommodate the holding-device when the ball is 'inflated.

The screwsthread connection between the cover-carried holding-device and the stem of the bladder has a number of important advantages. The bladder stem may be very readily attached to and detached from the holding-device, when the ball is deflated, simply by inserting a hand through the slit 2 and turning the stem into or out of the neck 4 of the plate 5,an. operation which may be accomplished by the exercise of the sense of touch alone and without any necessity for seeing the bladder stem 8 orthe plate 5, which of course are concealed or substantially concealed by the cover andthe hand while being thus manipulated into or out of cooperating engagement. But when the bladder is inflated tightly into engagement with the inner surface of the coverthe stem 8 cannot turn to work itself out of threaded engagement with the plate 5. Nevertheless, due to their threaded engagement, the stem 8 and the plate 5 may turn slightly one within the other during inflation. This ability of the stem and holding-device to turn slightly one within the other is of value in that it prevents the bladder from being inflated with the bladder in abnormal twisted condition.

The screw-thread connection between the bladder stem and the cover-carried holdingdevice is also advantageous because very strong and at the same time occupying less space than-any other form of connection with which I am familiar. o The small inflation aperture 3 in the cover, 1t will be noted, is substantially the diameter more delicate valve mechanism should the ball in play strike a hard object, and to provide proper protection against injury to those handling the ball from either the valve stem'or its holding member 5. In fact, in practice and as shown, I prefer to make the diameter of the aperture 3 somewhat less than the outer diameter of the stem 8.

By mounting the nut member or internally threaded neck 4 ofthe socket plate fixedly on the inside of the cover proper, I secure a dependableanchorage for the stem 8. Thus, in inflating or re-inflating, it is unnecessary to reposition the stem by manipulation through the insertion openin 2 because the bladder stem, evenwhen the ladder is deflated, will retain its proper relation to the inflation aperture 3. ,Not only does the stem-holding device fixed on the inside of the cover retain the stem in registry with the inflation aperture through the cover, but it also holds the stem up against the cover and against inward movement, thereby facilitating the attachment of a-pump to the stem.
