This offset s around the margin of the hole relative to the relation is indicated in the diagram' F18. 4 which 45 hinge 'or integral connection or the nrst tab, for shows the tab ,l in dotted lines larger than the instance, et the right of the opening, end if there tab la. Each tab is an integral part or its parwere three layers the flap for the third layer will ticular layer of balloon cloth and is strengthened,

In other words, these therefore the completed ball will be free from aps are inr displaced or staggered relationv to any protuberant portion or unevenne'ss at the '.g Sach other in respect tothe points where vthey point where the closing-of the opening in the 5 textile foundation takes place, so` that the ball may be of true spherical form.
A coat or layer of rubber may be applied to the exterior of the foundation of textile material as built up according to the foregoing description, and a veneer of leather panels L may form the outside covering for the ball.
The wax form may be coated with a thin lm of rubber or similar gum before-applying the fabric thereto. Each textile'fabric layer may be in a plurality of pieces to t the spherical' shape of the form of wax. 'Ihe leather veneer may be formed of a plurality of pieces shaped like the pieces of a base ball cover, having abutting edges without stitching, said cover being cemented to the outer layer of the ball and having its abutting edges cemented together.
Any desired form of lling valve may be employed indicated generally at 6, having capacity to c lose automatically when the lling nozzle is withdrawn, and access to the valve may be had through an opening in the closure tabs' and cover, or this valve may be located at any point removed from the tabs.
The ball before the leather veneer is applied may be placed in a mold and all parts bonded together under pressure and moderate heat. After the carcass isl completely bonded the leather veneer is applied through the medium of a vulcanizing cement which requires only relatively light pressure and very little heat, so that injury to and uneven shrinkage of the leather is avoided. Instead of a wax form a sectional form of metal, or other material, may be used, the sections being held together by suitable locking means, which lwhen properly operated will release the sections so that they may be removed one by one from wthin'the textile foundation through the open; ing 2 as described above.`
Where a wax form is used it may be meltedout by a steam nozzle.
Where the hinged end of one of the closure tabs overlies the free edge of another tab the latter will be reinforced, strengthened and rheld in its iiush position'relative to the fabric layer to which it belongs. M
n outer coating or layer of rubber may be applied -to the fabric by using two sectionsof hemispherical shape, or otherwise.
instance, a solid walledfcore or form la initially may be employed i. e. a hollow ball of wax without any pre-formed opening in its wall. 'I'he rst layer of foundation textile fabric is laid on this 55 -hollow ball and the outline of the hole or opening later to be cut therein and in the wax form is marked or-stamped on this layer. A thin piece of metal 'l of approximately the size of the hole to b eformd is placed on this fabriclayer within' thestamped or marked area where it will be held (i by the adhesive surface of thelfabrlc. The next layer of 'fabric is Ithen put on and rolled down' to unite with the first layer. Another metal piece la is 'placed on this layer of fabricsubstantially in registration with the first piece of metal.- Each succeeding `fabric layer is rolled down upon the preeding layer andis provided .with one-of the metalv pieces. All thec layers of fabric now will .have been cemented, one to `the other,l throughout their surfaces, excepting -where the 'metal' separators lie. Asan alternative .tlese areas may be coveredwith talc powder toA prevent adhesion ofY laminations during Vthe ,frlctional `rolling process, the talc, bypreventing cohesion acting.
75 as separators to permit the cutting of the` tabs 'I'he method may be modied'as in Fig.'6. For r j Under the method employed .by me the textile in the same manner as-prescribed for the metal separators. A tab is now cut out of the upper layer of fabric, the metal separator acting as a stop or shield to prevent the blade of the knife cutting through to the second layer. The tab 5 thus formed and connected integrally at one point with its own body layer is folded outwardly and the metal piece is removed. The next layer of fabric is cut in a manner `ust described, but in displaced relation to the rst cut so that its hinge or integral connection will be displaced relative to the integral connection of the first tab. Its tab is folded outwardly and its metal piece removed, and if more than two layers are provided the operation just described is repeated for each layer, until the wax or other form is exposed. Ahole is next cut throughl the exposed part'of the wax form so that a steam nozzle may be intrpduced for melting out the wax, or taking its pieces out if the wax form is broken up instead of .being melted.
The bladder, if one'is used, now may be inserted-and blown up and the'tabs may be'foldekddown onto` this bladder as previously described.
-By either of the above methods the opening made in thevfondation layer or layers of textile fabric may be repaired while still preserving uniiormity in the thickness of the wall of the ball throughout its extent whether at'or aroundthe margins of the opening in the ball, or throughout all other portions thereof. Y
It will be observed that the closure member being integral with the layers of the foundation material and made up of tabs displaced in respect to their relative points o'i' connection with their 35 respective layers constitute jointly, in effect, an integral continuation of the wall overlyingl the wall of thebladd'er and resisting the internal pressure of said bladder to prevent bulging out of the Vbladder at this point/ so that the spherical 40 formation `will be preserved. i
If four tabs are used displacedninetydegrees from each other, as diagram Fig. 5 shows. there will be an intact connection around the entire; margin of the opening distributed throughout the composite tab or closure Imade up ofthe four individual tabs cemented o`r united together. These intact connections are indicated at af--b--cA and d in Fig. 5. Where two layers are employed their tabs preferably would ne displaced 180 so," from each other around the center of the openmg' o A The invention is not limited to lin'e of the `tabs disclosed herein.
'I'he wall of the ball may be air-tight and em- 55 ployed without a rubber bladder. lSuch a wall would be made up of layers each having a closing tab orap for the opening through which the form may be removed, the tabs thereafter being Y united `by inserting a rubber foundation patch inside the wall of the case of a larger area than the opening, the rubber patch becoming a foundathe precise outtion member to cement the first tab to in lieu of A the bladder, cementing them together and vcemenungthe 'jointe between `themd and me may t54 of the cloth. The ball may be blown up and the cover sections of leather then may be applied. In this form of ball the textile material employed would be inextensible like in the form first de-` scribed.
wall A is thoroughly; lasted down after it has been patterned by material. That is to say,
to an exact form,/ removing surplus in :laying the textile material onto theform where surplus accumulations occur in the form of pleats in the relatively inextensible fabric used by me these pleats are cut-out leaving the material thus patterned with abutting edges in various extents according to the degree that these pleats occur, no stretching or tensioning of the fabric taking place. The size and form of the fabric wall is pre-determined according to the size of theform on which the ball is made. The subsequent action in a mold is merely for uniting the parts.-
The invention is applicable to balls other than spherically shaped. l e By employing' textile fabric which is relatively inextenslble accuracy of the prescribed shaper of the ball may be attained.
In Fig. 8 is showna form of closure in which the tabs instead of remaining attached at one point to themain part of the layer oi.' fabric to which they belong are in the form of separate pieces which are applied in superposed relation, and each cemented to the one next below it, each being ilushwith its own layer, so that the composite closurel will be-iiush'with the outer and inner surfaces of the built up wall of fabric layers. `The innermost tabwill be cemented to the bladder, or if the bladder is not used, then f. this innerclosure member will be cemented to a innermost layer.
The reference character la in Fig'. 8 indicates this patch, orit may be considered as representing the portion of the bladder which underlies the innermost? fabric'` layer. The patch sections indicated at 4b may be of diiferent diameters frto fit in their respectiveopenings in the fabric layers, so that the margins will overlap and thus break joints. These independent patches are, as stated above, each flush with the fabric layer whose opening; it closes, making a flush joint therewith. A
They are cemented oneupon another, and make up abompos'ite closure.
Where'featuresof oneJ form can lie used with features of modified forms described herein, said features may be regarded as embodied in said forms, for convenience off-illustration.l
