` 'llurning to Fig.` l', the sling is seen tocon- `'tl'aii'i broadly the elements oit a body and the swlnglrng-fcords orl thongs of thef ordinary r sling. j 'In use the'b'all l2 held by the body is 4retained by centrifugal force as the'device `is 'swung until one of the'cords, as 10,l is released,

when'the ball isdischarged.

Q"A"fminor feature of improvement shown Fi-glffl'lis in the loop device at the tree end fof Cord or thong 11. There is a soft elon-` gated flexible element 50, leather in my practice, apertnred at 51 to receive loosely the cord or'thongllwhieh is made fast to the oppofsiteend'otthe'element 5,0, as by apertnring ythemember 50 at 52 and applying a button or knot 58 lat the tree endotthe cord.fk `This censtruetion'lenables the operator to 'slip say his thirdinger into the space marked 54 and then passing the cord over the seeoncllinger 4of the same hand so that'when the cord 10^ is yheld between the lirstinger andthe thumb oithathand both of the cordsgl() and 11 are 'definitely under the control of the operators iingers and thumb iny making the-threw.V

The act of applying the'vcord llfirmlyand securelyto the` hand is thusrenderedsimple fand 'convenient,-tand` there are advantages,

Iftoo", inthe better sense `ofl teel andcontrol provided.

It will be observed that in the preferred form ot Figs. Lto 4 the` basey marked 7as a 95 VwholeB is substantially Lflatadjacent tothe ball, andin this respect, so .far asIknow, it distinguishes from` all other slings of Vthis f 1j charact'en 'l f f1 Thefyariousbases illustrated are shown as vwliic" entitledbyi the strengthy and `skill Tot fthethrowen` L *In drawings Figa-re f isa" perspective ot mynoyel" fslingcompletafexcept that the Fig(y EZYisfa4 itragmentaryftop fv'iew of the bodyilaid ont vstraight .with one" end extension `br''o'kei1;u,ifay;n.-" v w '1 n .showsithey deVice'ot/Figs: 1 rand 'EZ '59 fchieflyfin medial vertical'section y'but with being substantially fiat asa Whole, but this shape is to be understood as resulting from i Yhelrinds of material used Vin a construction which maires for convenience 1n manufacture, lightness and the desired strength.

The principal feature sought to be expresse-d Vin the fiat construction is the freedom .of the l bodylas a Whole from a.'pocket'-likeforma-l Y tion; adjacent to `Where the ball is seated.V

Note lin Fig. 3 that there are vlarge yopen spaces marked S between-the 'body and the ball.' In the old type of sling the .-ballisl hugged tightly, or `in the discharge areasL will be contacted by, the leather lat the ball, l areas facing these spaces S. Y I desire to 'avoid' all suchcontacts. rvThe'flat construction yillustrated and asis hereinafter more particu- Y ,y tionsvin constructicnnmay be made While still providing the `desir-ed free-dom ofthe `ball from such laterally contacting or. impinging' areason the bodyof the sling.v I f Y v .f Other characteristics of the base'vBare' that Lity vissosubstantially strong andv sti-fil that. it',` maintains its'desired shape,1especially as to .f

Turning to Fig?) thebody c-omprisesthe may be terinedthe Aends, of thebase. s These end yextensions should `beof some such strong and flexible. material as leather. Theyform mean-sf for securing Athesivinging elements as 10' aindllv to the body., an'd,a`s )shown "in Fig-ftlie upper'portions of the extensions Gland D are folded arounditheicords l0 and ll'at? lli and 15 and windings kofcordor Wire 16, and Ubind the'cords r1O-and 11 tightly.

rlhe vbasev part 22, being of. soft leather, would Y not maintain its desired shape. I therefore provide a fs'econd base element 23, which is' shownin the form cfa plate-like piece of strong, `stiff and quite rrigid material. Sole leathernis' suitable'for thepurp'ose.'` It is stitchedy at 24 'to the base elementf22, vand these two laminations kcombined form a rigid yetv springy' structure Vadapted to maintain the desired shape for sometime, but that' construction alone is not deemed by me sufficient bei', or Veven metal.

to provide thev v*desired rigidity for long life and service'. The part 23 could be of stiffer material vthan leather, for example hard rub- On theftop surface of base member 22 I provide tvvoguide members 25 and 26, which in .my practice are also of leather lstrongly stitched at 27 to the base ymember 22; These elements 25 and 26 further strengthen ther construction' tomaintain a' substantially: fiat condition of atleast these parts 25 and 26.A

Figs. 2 and 4 show that the guides 25 and 26 are spaced apart and are provided with downwardlyandfinwardly slanting surfaces V25a and 26a, against which the ball l2 rests.

As shown in Fig.l2 the ball may roll .freely onthese guides toward theextensions V@and D While being retained against lateral movey yments. It will beobserved that'theseguide` Ways 25aandr26a do not form lin any sensela pocket, and thatespecially theydo, not form a pook-et in the direction of the extensions C i and Dfi' The more rigid element 23eXtends suiliciently toward the lextensions Gandv vD to 'maintain-the spaces as S.H i Il [In order to provideabase which VWillfnot vbecome distorted an-dforma pocket-like con# dition where leather or the, like is used I have Y added fa third reinforcing element in the .forni of a thinplate Y30 (fliigs. 3" and A4) of iloeigwhich? material isf not onlytiff buttit ls also splghk nietalplate couldbeused inthe-same position.' l

VThe parts arestitched together at 36, and thevplate'fl() between'the laminations may be of suchmaterial as to providethe desired strength and 2rigidity, :preferably coupled with the slight yspringiness hereinabove Vpointed out. j The construction of F ig. 7v is peculiarly 'strong andserviceable, the parts .taking the lprin'cipaljstrains being'of double thickness.

` .L'Iuriiingfto Fig.'y 5, apart corresponding in various vrespectsto element 25 is marked 40 fand .thesame is strongly stitchedto the base "22? corresponding in z all 'respects to, they base -partQQof Fig..A 3. Instead 'of having guides providing that thejball may roll freely in bothV directions-th'ereare stop-means at one fend; and, asfillustrated, the downwardly Cil 1 slanting guidewsurfaces 41 terminate in a curved?seat. at The-openend of the Y "guides 141 istoward lextensionr C, whichm as i kwill be seen froniFig. 1,.is associated with je v l .r cord-10,fnamely, the cord to be released; Ihe

ball maythereforel roll freely-away from the seat part42 at'theinstant'of'release. The y tendency of the slingbody is to grip the ball chiefly on the sidethereof ltofwhich the releasable `cord`10 is secured,vv and I desire 'particularlly to avoid all 'counteracting contacts on that side]` The inodificationof Fig. 5 there- Vfore providesfor the desired freedom in the release from'theV side of the body chiefly involved., Partsnot illustrated in Fig. .5 and not specifically described may be; considered to be in' accordance with the preferred form except as to the plate-like piece 40.

" Inv Fig. G tlie plate-like lpiece 45 has a'downwardlyandv inwardly slanting circular scat 46 and departs yonlyjdn 'this respect from the preferred forni." In'l the use ofthe device ,ofFig'j 6 it will befound thatan` indentation i fot'the'V leather 45 Lisv formed at 47,showing 'that-at'the in'stantfof release ath'e part at 47 is obstructive, andy this ison the side of releas-v 'a-blecord 10.5 In this respect the `device of Fig, 6 is not as satisfactory as those ofthe f other illustrations ;fbut a sling constructed iu "accordance with Fie". 6 would be greatly superior to one built along the old lines in which the ball is pocketed and contacted at areas facing the spaces S in Figs. 3 and 7. The

grip upon the ball at the small area 47, while I being. of the kind which I'desire to avoid, relatively slight, and even this may be avoided by a greater resiliency in the base than I v would -ordinarily employ in connection with the other devices shown.

Such slings are ordinarily used with a swinging overhead motion in 'a substantially :horizontal plane forbest directional effects `with good distance, with va sortl of diagonal "ball weighing from two to ve ounces is suitable for accurate throwing and good vdisi tance. vWhile'stones and other irregularobjects could be :thrown to advantagein the `present sling, my chief object is tofprovide an appropriate sling for use in a game'to beplayed over a ycourse or courses laid out in anopen field, and I therefore suggesta ball as'thefmost suitable missile, with the sling` body particularly adapted to the use of a spherical object. i
