Harwood & Sons, Inc., Natick, Mass., a corporation Y of Massachusetts Application March 14, 1933, serial No. 660,684' 21 claims. (o1. 11e-262)* j This invention pertains to ,playing balls,-par `ticularly to baseballs foroutdoor or vindoor use, and relates more especially to an improved coverseam for such balls. In accordance with usual methods baseballs are provided with covers con-` sisting of two independent pieces which are sewn together with their edges in abutting relation. The `most common practice is to employ two sewing threads and to form a substantially :datseam in which each thread extends diagonally first in one direction land then in the other in uniting the cover members.

During use, a baseball is subjected to heavy blows, moisture, grit, harsh friction, etc., and While the cover material itself may withstand such hard usage for a reasonable length of time, the seams soon loosen and tend to open, and the sewing threads fray and break before the body of the ball `shows any substantial sign of deterioration. As noted, the usual baseball seam consists whollyof stitches extending diagonally across `the line of union of the cover parts. Apparently this diagonal arrangement of thestitches is in part responsible for the loosening of the seam after short use, it being evidentV that the line of pull of such a diagonal stitch is not the most effective for holding the edges of the cover parts in close contact, since the pull exerted by such a `diagonal stitch has a component extending lengthwiseof the seam. Thus any creep of vone coverpart relative to the other tends to openthe seam, while if such a diagonal stitch be drawn veryv tight, it tends to pucker the material of the cover so that the stitch tension itself has a tendency to open the seam at points between the stitches.,

In accordance with the present invention the parts of the cover are united by a seam which, at intervals at least, comprises thread runs extending perpendicularly to the length of the seam so as to exert a direct pull having nolongitudinal component. Thus, when such runs are drawn tightly, the only tendency is `to pull the edges of the cover material into firm engagement and as' the length of thread now extending from cover member to cover member is a minimum, relative creep of the cover parts increasesthe stitch'tension, while the loosening effect of stretch inthe thread becomes less apparent than when diagonal runs are depended upon to unite the parts.

Preferably a perpendicular run of one thread is always associated with a similarV run of the other thread, thus affording a connection having double the vfull strength ofl a` single thread, and in certain embodimentsrof .theinvention all of the perpendicular runs Vare disposed within the cover where they are protected from injury.

In certain Ypreferred embodiments of the invention the uniting threads are so disposed as to forma row of stitches extending longitudinally of the line of union of thecover parts at each side of `such lline of union, and these longitudinally extending stitches reinforce the cover VInaterial adjacent to its edge, thereby tending to prevent stretch of the cover and so assisting in maintaining a tight and close joint.

In certain embodiments of 'the invention, runs of the threads extend across the'line of union of the cover -parts at the` outer or exposed side of the seam, Vor at least as far as the line of union, and across the margin of one cover part, thereby holding vthe marginal portion of the cover part closely against the ball body; moreover, in certain instances, transverse runs of the threads may extend through the thickness Vof the marginal portions of the cover material so as to hold the latter down without exposing the runsgof thread.

Certain embodiments of the invention produce a somewhat prominent seam projecting slightly above the general surface of the ball as compared with the so-.called iiat seam in common use, but not projecting so prominently as the welt or so-called fout-seam sometimes employed in baseballs, particularly playground balls, and which is objectionable by reason of its great prominence and tendency to injure the player. In certain embodiments A,wherein this slight elevation of the seam material ispresent, the crossing runs at the exposed surface of the ballmay be drawn so tightly asv to sink partially into the material of the cover, thus causing the marginal portions of the cover parts to `protrude between successive crossings of the thread, forming in effect a series of prominences bounded in whole or in part by exposed runs of the thread.

Referring to the vdrawings, and particularly to Figs. 1, 2,"3 and 4, theball comprises two cover members 1 and 2 shaped in the ywell known manner so that when their cut or raw edges'y are in abutting relation they form a complete cover for the spherical bodyv Bof the ball. In' accordance with the preferred construction illustrated in Figs. 2 and 3, the seam which unites the cover members l and 2 is formed from two independent threads so disposed as to provide substantially parallel stitch rows 4 and 5, respectively, at opposite sides of the line of contact 3 of the abutting cut or raw edges of the cover members 1 and 2.

In forming this seam, one of the threads'is arranged to form a stitch 10 of therow 4 directly opposite a stitch 20 of the other thread forming a part of the row 5. The thread forming the stitch 10 passes inwardly through an opening 6 in the cover member v2, thence across beneath the marginal portion M2 of thecover member 2 to form the run 11 which extends as far as the line 3 at which the cover members abut.v This thread then passes out between'the edges of the -cover members to form the run 12 overlying the'margin M1 of the cover member 1. The same thread then passes inwardly through the opening 7 of cover member 1 and extends transversely across beneath both margins M1 and"M2, that is to say, between the cover material and the body of the ball, forming a run 13 extending substantially perpendicular to the line of abutment 3 ofthe cover members and emerging again through the opening 6 in the cover member2. This thread then forms a second-stitchh14` of the row 4, passes in through the opening 8 and beneath both margins M? and M1 of the cover materiaLform ing the run 15 extending substantially perpendicular tothe linel of abutment 3 of the edges of the cover, and then emerges through the open` ing 9 in the cover member 1V Vto form a stitch'16 of the row 5V. The thread which forms the stitch 20 passes through a similar 'courseprovlding for example, the run 22 at the exposed side of the material overlying the margin lVI2 and then passing beneath the margin M1 at the line of abutment of the cover members, where'it crosses the first thread at that'point where the run 12 of the latter emerges from behind the margin M2, and

after passing beneath the margin M1 the second thread appears again through the hole 7 to form the stitch 24 of the row* 5. This thread then passes in through the opening 9,-transversely across the line y3, and out through the opening 8 to form the stitch 26 of the row 4.

It may be noted'that between the holes 6 and '7v runs of both threads extend completelyacross.

fromy one row 4 of stitchesto the other row 5, such runs being taut and substantially perpen- 10 .dicular to the abutting line 3 of the cover material, and that between the holes 8 and9 runs v of both threads likewise extend across from one row of stitches to the other row. Thus between each pair of opposite holes 6 and 7, and 8 and 9.

parallel runs of thread, such runs being perpendicular to the llength of the seam and being adapted to draw the` cover material into very rm and close engagement. At the same time,

at -'alternatepairszof holes,` as for .example'be-- tween the holes 6 and 7, each thread forms a run which extends firstl atfthe outside ofr the cover material f andwthenwat the inside thereof, thus binding the edge of the 'cover down firmly against thebody of the ball." Likewise the rows 4 and 51v of stitches spaced from the edge of the material Y reinforce the material andprevent its stretching 15v respectively, there lare two taut substantially.

When in the present description'and claims, y

reference is made to runs of thread' extending perpendicular Vto the'line of abutments of the cover parts, it is notl thereby intended to intimate any exact mathematical relation, since 'not' only may'the opposedholes' of a pair be slightly kout of alignment, but the threadsA tend totwist and in crossing to displace'each other, and thus the expression perpendicular run 'is' to beinterpreted as'meanin'g generally or substantially" perpendicular in Yeach case. 1 'Y Inr Fig. 2a a slightly modified constructionis shown wherein `the run 22e of one of the threads,

correspondingv to the vrun 22 of Fig. v2, 'passes through-the lthickness of the marginM2 instead' of across the exposed face of such margin, yand then passes downl between the abutting edgesy of the coverl members and beneath' thefmargin -Ml of the cover member 1 to form .therun'zlag Like- Wiserthe-V run 12a of the other threadiextends through the thickness of the ymargin Mland then down between the abutting edges and beneath.

the` margin :Mfto form the run 11e. v'I'his construction is preferred undersome circumstances,

since the threads are not exposed-transverselybf f theseam,A but it is s cmewhat'more diflicultfto make and rthus more expensive.r It may'be noted by reference Ato Figs. 1,l 4 and 2afthat the result ofthis methodof forming the seam is to cause the cover material to protrude or project 'slightly of theball above the general spherical surface between the'rows 4 and5 of stitches, but While the y seamis thus somewhat prominent, it is not nearly so prominentas y,the usual out'seam employed, for example, in playground balls, and while af-v fording a good grip, to the player as'is often `occasioned by the heavy out-seam commonly provided.' j Referring'Y to Figs. 5, 6` and 7, ainodiiied con` is not liable ,to cause injury structionfis illustrated in which theball comprises the cover members 1'a and 2a abutted at their edges Iand secu-red together by the seam construction shown in detail in Figs. 6 and 7. This seam is likewise formed from two threads and these threads form parallel ro-ws 4a and 5a of stitches spaced from the 'abutment line f3'EL of the cover members. One of the threads, for example, may form the stitchl30 of the row 4a, then pass inwardly through the opening 6a andbeneath both of the margins M2 and M1 of the cover, 'and thence out through the opening 7a, it being noted that this run of thread extends substantially per-- pendicular to the line 3a. The thread then extends along the surface of the cover member 2a to form the stitch 32 of the row 5er-then passes in through the opening 9a transversely across and beneath both margins 'to ormthe run 33, and thence o-ut through the opening 8 `where it forms the exposed stitch 34 oi 'the row 4a. The other thread forms the stitch-4'() `of the row 5a, opposite the stitch 30, then passes in through the opening T12-across in a run 41 to the opening Sar-then forms a stitch in the row 4a, then passes across perpendicular to the line 3a andl out through the opening 9a. y

In this construction, 'as in thatpreviously de-` scribed, a pair of thread substantially perpendicular to the line of abutment of the two cover members, extends across between each pair of opposite openings in the cover parts, thus very firmly uniting the covers to each other with a minimum possibility ofloosening by stretching of the threads and without any tendency to pull the cover parts longitudinally of the seam relative to each other. 'It may be noted that in this construction a stitch 30 of one thread alternates with a stitch of the other Vthread in each ofthe rows 4.a and 5a;

Referring to Figs. 8, 9 and 10, a further modification is illustrated in which the ball has the cover members 1`b and 2? abutting each other at their edges and held together by the seam construction shown in Adetail in Figs. 9 and 10. This seam structure is formed from two independent threads arranged so as to provide rows lband 5b, respectively, of stitches at opposite'sides of the junction line 3lD of the cover members. Thus, for example, one thread may form a stitch or" the row 4b exposed at the surface of the cover member 2b, while the `other thread forms a similar and oppositely arranged stitch v yof the rowb. The thread which forms the stitch 50 then passes in through the opening '6hforming the run 5lr beneath the margin M2. This thread then emerges between the abutting edges of the cover parts and forms the vexposed diagonal run 52 on the outer surface of the margin M1. This thread then passes in through the hole "lb" and forms the transverse run 53 (Fig. 1G) substantiallyY perpendicular to the line 3b,-t'hen'emerges through the opening 8b and forms the exposed stitch 54 of the row 4b. This thread then passes in through the opening 9b to `form a diagonal run behind the margin M2 similar to the run 51. In like manner the thread which forms the stitch 60 extends diagonally across,l forming the partially exposed run 62, then transversely from the hole 8b across to the hole 7b beneath the cover material,-then forms an exposed stitch of the row 5b, and then passes in behind the margin M1 to form another diagonal run.

This construction provides pairs of `runs or" thread substantially perpendicular to the line 3b, but at alternate pairs oi" holesinstead 'off at every pair of holes as in .the previous instances. However, these runs, extending perpendicular to the seam line 3b, draw the coverimembers firmly together, while the diagonal runs, which are partly inside and partly outside of thecover material, help to bind the `cover rmly against the body of the balli Thisseam, whilepossessing many of the desirable characteristics of that of Fig. 2, for example, is somewhat easier tomake and requires less material, and thus may be made more cheaply than that shown in Figs. l, 2 and 3.

Referring to Figs. 11,12 and `13, a still further arrangement is shown which Vprovides pairs of runs of thread extending perpendicular to the seam line at each pair of opposite openings, and

inaddition provides diagonal runs of thread at the exposed surface of the cover adapted to hold the cover nr-mlyagainst the ball body. This seam is'formed of two threads in the same way as the others, and one of these threads may form the stitch '10, for example, of the 'row 4c in the cover member 2C, such thread then passing in through the opening `6 and then transversely across and beneath both margins M2 andlVI1 and perpendicular to the seam line 3,-then merging through the opening 7c of the cover member 1G. This thread then passes in an vexposed diagonal run 72 across the seam line Bcf-then in through the opening 8,-across in a run 73 perpendicular to the seam line, and out through the opening 9c where it forms an exposed .stitch '74 ofthe row` 5C. In the same way the other thread, which forms the stitch 80 'opposite the stitch 70, extends in through the opening '7c forming the transverse run 81, the-n out through the opening 6c to form A the diagonal run 82, then in through the opening 9 and out through the opening 8cr where it forms the stitch 84 of the row 4C. It may be noted'that in this arrangement the exposed diagonal runs` 72 and 82 cross each other substantially on the seam line, both runs being on theoutside or the cover material and that in this arrangement alternate stitches of the rowslc and 5c are formed by the two respective threads.

In the arrangementshown in Figs. 14, 15 and 16, the ball comprises the cover members 1d and 2d and the seam vconsists ci two threads as in the previous instances. One of these threads may form the diagonal run 90, for example, exposed at the outside of the cover and which passes in v through the opening 6d,-then transversely across substantially perpendicular to the seam line 3d and out through the opening 'FR- then forming another exposed diagonal run 92 extending across the seam line. In the same way the other thread forms the diagonal run 100, crossing the seam line 3d beneath the run 90, then passing in through the opening 7d and transversely across in the yrun 101 substantially perpendicular to the seam line, thence out through the opening 6d to form the diagonal run 102 crossing beneath the run 92 of the other thread. I

While this seam structure possesses certain of the characteristics of those previously described, for example, the provision of pairs of runs of thread extending transversely across perpendicular to the seam line, such pairs extending across 'between each successive pair of openings, and also has diagonal crossing runs at the exposed surface of the ball adapted to hold the cover nrmly against the body of the ball, it may be noted that this arrangement does `not provide the longitudinal rows of stitches which, as above noted, add to the strengthdof the cover adjacent to itsmargins, thus helping to prevent .stretching of the cover and loosening ofthe seam. However, while the seam shown in Figs. 14 to 16 does not possess all of the desirable qualities of those previously described, it is easy to make, requires less material, vand is thus cheaper, and under some circumstances may be preferred.

While I have herein illustrated certain desirable features of the present invention by way of example, I wish it to be understood that the underlying principles of the invention are capable of embodiment in other specific constructions and that all such modifications as may be regarded as equivalents of the` construction herein disclosed are to be considered as falling within the scope of the present. invention as expressed f in the appended claims.
