FOOTBALL.

Application filed January 9, 1525. Serial No. 1,362.

P vide a football which is more durable than those of the prior art with which I am acquainted.

Another object of my invention is to secure the results sought in each and all of the aforesaid objects in a football which can be manufactured inexpensively and without the provision of special machinery therefor.

Other objects of my invention and the nature of the invention itself will become readily apparent as the description of the specific embodiments thereof progresses and lIlWlllCll description reference will be had to the accompanying drawings forming a part of this specification.

Referring to the drawings-Fig. 1 shows a side elevational View of an embodiment of my invention, a fragment thereof being shown as broken away so as to make a portion of the view in longitudinal, medial section for the purpose of disclosingthe structure of the inner parts.

Fig. 2 shows a transverse, medial section of the embodiment of Fig. 1.

method of making up the seams of the ball and the relative positioning of the different arts. i p Fig. 6 shows a view similar to that of Fig. 3 of a casing wall comprised inuanother embodiment of my invention. Fig. 7 showsa like view of a similar other casing wall of the ball of Fig. 6.

Fig. 8 shows a like view of third wall thereof.

Fig; 9 shows a view similar to that at Fig,

3 of a casing wall of a third embodiment of my invention.

Fig. 10 shows a like view of a similar other wall for the ball illustrated.

Fig. 11 shows a third wall of the ball of the Figs. 9 and 10.

Fig. 12 shows a wallet? a ball which is a fourth embodiment of my invention.

Referring now first to the embodiment of my invention illustrated in Figs. 1 to 5, inclusive, I preferably construct the ball of my invention by securingthe edges of four casing walls together, asby stitching the same with threads projected through adjoining edges of the walls, as illustrated at 2. i The walls of the football of my invention comprise, first, an outer layer 3 of leather which is soft and pliable as commonly employed for such purposes,- the outer casing being preferably, as is the custom, in foreign segments as illustrated in Figs. 1 to 5 at 4, 5, 6 and 7. On the inner surface of each said Well, I face the wall with a fabric covering such as coarsemuslin or like canvas, the same being stitched at its borders to the borders of the leather, by the stitching threads 2 illustrated at various places in the drawings.

So far as the description of this first embodiment of my invention has progressed, it is of the common form of foot ball now well known in the art. To the inner surface of the plurality of walls, such as the walls 4, 5, 6 and 7 of sucha football, I secure a rubber band or girdle Sextending from seam to scam of each ofthe walls on the interior surface thereof, the same being secured to the walls by stitching it together with the canvas lining therefor directly to the borders of the leather facing 3. I then consolidate the four walls of the football into the form of the plain ball by sewing the walls together at their edges as described and turning the ball inside out until it takes the form illustrated in Figs; 1 and 2.

The form taken by'such a ball previous to being turned inside out is that shown in Fig. 5, which represents theball which has been manufactured by consolidating the four walls into an integral ballcasing by stitching these walls together with their linings and the elastic band or girdle for each wall section shown at 8.

Such a ball casing constructed as ldescribed will haveanuelastic rubber'bladder 9 placed within the casing through the opening 10 provided in the casing and which opening may be closed by laces 11, such as commonly provided for the purpose, and the bladder inflated by pumping air into the same under pressure through a duct 12 and which duct may be closed thereafter by doubling the tubular wall thereof back upon itself and securely tying it as shown in Fig. 2 in the customary manner. Such a ball when inflated will become distended as shown in Fig. 1, the ball in all transverse cross sections. becoming approximately circular and in all longitudinal cross sections being oval, and the seams between the casing sections will be turned inwardly as illustrated at 13 in Figs. 1 and 2.

I find that a band of soft, relatively thin, pliable and flexible rubber stitched in this way at its ends to seams at opposite borders of the casing wall segments perform the function of weighting the ball, at the same time forming together with the other rubber band portions of the ball which altoget-her comprise a substantially c osed band of rubber encircling the ball, secures for the ball a degree of additional resiliency not had in plain balls without this rubber inner band, and that such weighting is balanced so that the ball will not, due to any unbalancing effect of the weight thereof, travel through the air after being kicked in a direction at variance to the behavior of a like ball with out the rubber material contained there, as described.

I find that also due to the fact that the rubber material is of perceptible thickness the bladder 9 which by its contained air under pressure is forced into intimate contact with the inner surface of the rubber band 8 and the other inner casing wall portions which flow over the adjoining portions of the rubber material and the inner decrease in tensile stress at other points and will cause the weight to be unequally distributed, and in some cases causes the life of the bladder to be decreasd as well.

I have found that it is impracticable to secure the advantages of increased weight and resiliency hadwith a ball of my invention to merely increase the thickness of the wall of the bladder, since when this is done the bladder wi l not flow around the inwardly protruding seams between the casing wall sections to a degree which will cause a gripping between the bladder and such not as resilient as one constructed in accordance with the above description of an embodiment of my invention wherein the additional rubber material is applied to the inner wall of the casing sections and not to the bladder.

Another advantage of facing the inner wall of the casing with rubber material is that the rubber material of such casing inner wall will. adhere tightly to the rubber material of the bladder, since rubber against rubber has a high coefiicient of friction as compared to rubber against canvas and rub ber against leather, and like material, which might be employed in plain balls.

In Figs. 6 to 8, inclusive, I illustrate another form of my invention wherein the rubber bands are, as shown at 15, 16, 17 and 18, secured along the borders of each of the wall sections, being stitched at 19 along an edge of the rubber bands which are curved in form so that the stitching at a remote point 20 for a band 17 for instance, is at an opposite end and in line with the stresse set up in the band to a point 21 at the other end thereof, the same being true of the other bands 15. 16 and 18.

The band 22 isin two parts since the inner lining of leather 23 for the;throatjof the casing is stitched as shown at 24 to join the sections 22 and the rubbermaterial pro vided in the other bands is omitted between the 'two sections 22, since the additional leather facing 28 will give the weighting otherwise given by the omitted rubber portion.

The construction on the opposite side of the seam shown in the upper part of Fig. 7 is similar to that shown for the upper side of Fig. 8, except that as illustrated in Fig. 8 there is a flap 25 secured by stitching 26 to the wall of the casing, this flap having an aperture 27 adapted to be passed over the tubular duct such as illustrated in 2 at its 12 for thebladder and through which duct like the portions 22 of Fig. 7, separated but joined by the leather 23.

In this embodiment of my invention which is illustrated in Figs. 6 to 8 by views of the inner walls of the football casing," but with the football turned inside out to expose the inner construction and to illustrate as well the step in the manufacture of the casing prior to the turning of the casing inside out,

the rubber bands extend longitudinally of the ball instead of transversely, as in the case of the band 8 for the wall sections of the first embodiment of my invention described. The advantages, however, are like in kind though different indetail and I may employ either construction and secure such advantages,

Referring now to the embodiment. of my invention illustrated in Figs. 9, 10 and 11, in this embodiment I provide an inner lining of rubber for each of the sections of the rubber casing applied directly to the inner surface of the leather outer casing segments and stitched thereto at the border portions of the rubber and leather sheets, as shown at 2. In this embodiment of my invention the effect, substantially, is to pro vide an entire rubber lining for the ball outer casing, and reliance is placed upon the coefficient of friction as between two rubber surfaces, the material being soft rubber 01' like elastic material having a high coefficient of friction for adherence of the rubber bladder to the walls of the casing and without becoming displaced within the casing, in addition to the reliance placed upon the inwardly turned seams, faced with rubber at their sides for holding the inner bladder in place.

In the embodiment of Fig. 12. I stitch the rubber to the canvas only, at points closely adjacent the stitched seams joining the sections. By so securing the rubber to the inside ef the casing I find that the tendency of the seams to spread apart on the exterior of the completed and reversed ball is eliminated, and the same results secured as in the other embodiments. In the broadest as pects of my invention it is only important that the rubber girdle or band within the casing; be properly distributed within the casing and intermediate the casing and inflated bladder. In some embodiments of my invention I even propose to eliminate the stitching entirely, though for most purposes I prefer that the rubber be securely fastened to the interior of the casing.
