17 Claims.

My 'invention relates to inflatable balls such as basket balls, foot balls, andthe like, comprising an outer casing, usually of leather, and

an inner bladder, usually of rubber. My present 5 invention is preferably embodied in casing constructions having a bladder `inflation aperture spaced away from the customary laced bladder insertion slit or opening. l

The object of my present invention is to improve the anchorage whereby the bladder with its inflation valve is held against the inside of the cover in association with the inflation aperture. Among the outstanding advantages of my invention are the provision of: a quick detachable anchorage `tor the purpose described; an anchorage'which does not require the time nor the awkwardness of turning the bladder within the cover as in the usual screw type anchorage; a quick detachable anchorage which will still permit of relative rotation of the bladder and cover prior to complete inflation so that the bladder may adjust itself without straining the bladder at the region of the valve; an anchorage requiring a minimum dimension in a direction radially of the ball so that the bladder, even at the Vregion of the valve stem may lie close to the cover; and an anchorage which, while being quickly detachable, will hold the valve of the bladder in position relative to the casing and lagainst any ordinary lateralfor inward movement occasioned by the attachment or detachment of the usual air pump. Another feature of my invention is the simplification of the stitching necessary to the assembly of the anchorage members.

These together with other objects, features and advantages of my 'invention are set forth in the following description of a specific emin the attached drawings, wherein v Fig. vl is a perspective View o f `a basket ball embodying my invention, a portion of the cover being broken away to reveal the anchorage;

Fig. 2 is a plan View of the inside of the ball showing the cover-carried anchorage member;

Fig. 3 is a perspective detail of the covercarried anchorage member illustrating how the bladder-carried button member is inserted therein;

Fig. e is an enlarged transverse section taken on the line 4-4 of Fig. 2 but showing the bladder-carried anchorage member positioned 'in the cover-carried anchorage member;

Fig. 5 is an exploded'perspective of the several pieces of the cover-carried anchorage member of Figs. 2 and 3; and 1 Fig. 6 is a section somewhat similar to Fig.

4, but showing only the bladder-carried members, and illustrating a modication wherein the head of the stem is Vformed by ajnut'threaded on to the end of the stem. j

vThe basket ball shown in Fig. 1 has a leather cover 10 with the usual laced opening or slit 11 through whichv the rubber bladder 12 is inserted. Y

The bladder 12 carries an innation, check valve 13, preferably of the Schrader type, yhoused in avalve sternV 14, the major portion ofV which extends inwardly through the Wall of the bladder. A-minor length of the valve 'stem extends outwardly beyond the wall of the bladder and carries an enlarged disc-shaped button 15. The button is spaced outwardly a short distance from the wall of the bladder. The bore of the 7.5' Valvestem, which also passes through the button vportion '15, is preferably internally threaded to receive the coupling of an air pump, and the bore of the stem constitutes the air passage for the ination of the bladder. 1

Access to the valveY stem from the exterior of the cover is had through a small linflation aperture 16 through the casing, the aperture being preferably about the same diameter as the valve stem so as to accommodate the coupling member of the usual air pump. This inflation aperture is preferably spaced from thellaced bladder insertion opening 11 and, for the purpose of balance, is preferably spaced about' 180 degrees away from the opening 11.A

The cover-carried anchorage member which cooperates with the kvalve stem button l5 to hold the valve stem in proper relation to the inflation aperture 16 comprises a set of three superposed disc-like layers: 95'

The first of theseyll, is a cushioning or buffery layer laid directly against the inside of the cover (or, if the cover has a'lining 10', then directly against the inside of the lining). yThe, cushioning member has a central aperture 17 registering with the aperture 16 of the cover, and preierably of substantially the same diameter. "A

The second disc, 18, is substantially the same thickness as the button 15 of the valve stem and has av central aperture but slightly larger than 105 the diameter of the button.

The third disc, 19, is of a thickness but slightly less than the distance by which the button 15 isspaced fromv the'wall of the bladder," and it 1 Ahas a central aperture but slightly larger than bladder is ofcourse wholly or at leastpartially When this is done the flaps of the disc 19 form the neck of the valve stem adjacent the button 'Ihis third disc 19 has a radial slot 20 extending from the central aperture 19 to the periphery, the width of the slot being substantially the same as the diameter of the neck of the stem, and preferably being outwardly iiared near the periphery of the disc to facilitate the entry of the Ynecktof the valvestem there-along. The side of the periphery of the innermost disc 19 adjacent the mouth of the slot 20 ispreferably truncated or cut away at 21. The three superposed discs 17, 18 and 19 are secured tov` gether and to the inner side of the wallvlO'by a circular stitching 22 passing through the cover and the three discs adjacent the periphery of the latter. Becausel of the cutting away 'at 21 of the periphery of the third disc 19, the edge of the disc adjacent the mouth'of the slot 20 falls radially Within the line of stitching and forms a pair of opposed naps which can be raised to` a" limited extent to permit the passage ofthe button' 15Y between' theN iiapsY and' the 'face' 'of the second disc 18. To preventy undue strain on the 'bladder wall by an abrupt step-down, the discs are preferably of progressively Vincreasing diameter'arid their edges 'are preferablyrtapered off a'sindicated at 23.

However, the periphery of the third disc 19, Whereit'istr'uncate'd at'21, is preferably trimmed so' that its edge tapers in opposite direction as indicated at 21 to facilitate the insertion of the button 15 -beloW the opposed flapsforming the's'lot'ZO. 'f 4 To anchor the bladderrto the inside of the cover with my improvedanchoragemeans, the

deflatedandinserted int the cover through the unlaced opening 11. The bladder is held in the handwith lthe fingers grasping'it at the region of the valve stem 14, and the button 15 iS brought into position, as shown in Fig. 3, in alignment with the slot 20 and with the rounded periphery o`f the button engaging the reversed tapered edge 21' of theA third disc 19. The lbutton is moved laterally toward the central Vaperture 19 with i the button itself moving'between the layer 19 and the layer 18 and the neck of the valve stem passing along the slot 20V V'until it reaches the aperture 19, when the button drops down into the 'central aperture 18 of the second disc 18.

ing the margin of the slot 20 again resume their normal position A'in Contact with the face of the second disc 18, and the button is snugly locked in the cavity formed bythe aperture 18.

This attachment is lvery quickly effected, it not being necessary to turn the bladder. Should the bladder-especially inthe instance of a footballnot be axially aligned with the cover, my anchorage permits of the bladder and the bladder stem turning in the cover-carried anchorage member properly to align the bladder. After the bladder insertion opening 11 in the cover is laced up', thecoupling of any air pump may be inserted from the exterior of the cover through 7 the'inflation aperture 16 and threaded into the bore of the 'valve-stem 14, and the bladder inl flated. The disc 19, during such attachment of the pump,'prevents the valve stem being pushed inwardly out of reach of the pump coupling or l out of registry with the opening 16 in the cover;

The discs 18 and 19 together prevent lateral movement of the valve stem out of registry with the opening 16 in the cover. After the bladder has been Vrfully iniiatedyitsinternal pressure Vmetal button 15 and also to provide additional resilience between the exterior of the cover and the metal valve to protect the valve and to provide s ucient resilience so as not to give any eccentricity to the rebound in the event of impact in thevicinity of the ination aperture 16.V

vIt will be noted that in addition to simplifying thevv operation of attachment and detachment with my improved anchorage means, and the elimination of the necessity for turning the bladder within the cover to effect the attachment, I have provided an anchorage means which is very simple and which includes no vinterengaging parts Which'are subject to wear 'or breakage as in the instance ofthreadedcouplings'or Vsnap type'couplings;v

If desired, my invention may be adapted to utilize' the presentv commercial design of 'bladders made for use With the'screw' type anchor-'- age, by more or less permanently threading upon the protruding externallyv threaded'valve stem lalsee Fig. 6) an internally threaded bushing 425 .comprising a neck portion 26 vand "a but# ton portion 27 corresponding tothe button 15 v01" Fig. 4.

Amaybe carriedv by 'the bladder andV that the metal`next to Vthe cover is minimized, as comi pared to 'a construction where the arrangement would be'reversed, that 'is,'where""th'e button member would becarri'ed by the cover and' the slot member. by the bladder.

I contemplate that other changes also may be made over the specific embodiments herein dis# closed without departing frorn' the spirit or scopeof my'invention.
