1 Claim.

together by a novel form of stitching that will be stronger, and much more durable and re sistant to Wear than the conventional V-shaped ball stitch hitherto employed, but which will not require more cover material, extra lining for the cover material, much more thread, or much more labor and expense than would be necessary lign 1tlhe manufacture of the conventional V-stitch Another object is to provide a style of cover stitching whose tactile characteristics aresuch as will enable the player to hold the ball much more firmly than hitherto, but without producing a sense of undue roughness.

Other objects, advantages, and desirable features of the invention will appear in the course of the following description of an illustrative embodiment of the spirit thereof.

In the accompanying drawing forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a perspective view of a ball made in accordance with this invention;

Figure 2 is a fragmentary enlargement view particularly showing the novel form of stitchins;

Figure 3 is a fragmentary View of the inside of the partly stitched cover; j

Figure 4 is a fragmentary section, taken on the line lt in Figure 2;

Figure 5 is a fragmentary section, taken on the line 55 in Figure 2; and

Figure 6 is a fragmentary section, taken on the line 6-6 in Figure 2.

The invention may be embodied in a ball having the usual wound-thread core i and the conventional cover sections 2 and 3, provided along their edges with the usual pre-formed perforations 4. The two threads 5 and 5 maybe of any through the next perforation 4 on that side of the edges 8 to the inside of the cover, and thence straight across, underneath, as at if], to the perforation l directly opposite the last-mentioned perforation 4, and thence therethrough to the outside of the cover. The thread 6 is then passed through the perforation 4, located directly opposite the aforesaid first-mentioned perforation, and thence, as at H, diagonally to the left and forwardly across the first lap Q of the thread 5, thence through the aforesaid thirdmentioned perforation to the underside of the cover, and thence coextensive, as at E2, with the last lap iii of the thread 5 and into and through the perforation directly opposite. The

repeated until the double course of stitching has been completed. It may then be continued to overlap a few of the initial; stitches, as shown at I3, Figure 1, and then the threads may be severed at the end of the last stitch, the over lapping beingsufficient to hold the ends securely.

It will be observed that the double courses of stitching 5 and 6 form a series of straight lines at right angles to the seam 8 on the underside or inside of the cover, and the outline of a series of contiguous rhombic or diamond shaped fig ures 14 on the outside of the cover. The thickness of the threads on the inside of the cover produces an elevation of the figures Hi, maintaining them in relief against their outlining threads, and so shields the threads to that exte'ntagainst abrasion. Furthermore, should one of the threads on the outside have one of its stitches cut or beaten through, the adjacent stitches of this thread will not become loose, because they are frictionally held secure by the stitches of the other thread. Furthermore, even arrangement, order, or use of parts, as it is evi,

dent that many minor changes may be made, therein without departing from the spirit of this invention or the scope of the following claim.

In a baseball, a core, a pair of cover sections having' opposing edges in abutting relation, a

pair of courses of stitching having their free ends formed into V-shaped configurations and embedded in the said core, the said pair of courses of stitching respectively extending from 5 one section to the other on the outside of the cover to form rhombic stitch patterns and further respectively extending from one section to the other in abutting parallel relation across said edges at right angles thereto on the inside of the cover to elevate the portions of the cover confined within the said patterns.
