Patented Feb. 3, 1931 UNITED STATES @if WALTER ANDERSON, or KILLINGLY, coniiacrrcur,v Assicr'Noie ,To ANDERSON viuI'IQIJfv SUPPLY COMPANY, or xrLLrNGLY, co,NNncrrcunr,yk A coRPonA'rroN. yorV coN- NEGTICUT .Y Application inedv :nine s, 1e2s""'ssr i1 Nbieeavs'es." 'I l i This invention relates to lug straps such as are used in connection with the picker sticks of weaving looms for throwing the shuttle from end to end of the hatten, and has more particular reference to lug straps of that classhaving an integral reinforcing cushion of the fulcrum or roller type. l

Lug straps of this class areordinarily constructed of less width Vat and adjacent the bend than at the ends, the intermediate portion` of the strap being upset or compressed edgewise to so reduce the-width and to force the surplus material inwardly to form a reinforcing cushion havingia curved .surface adapted to give a roller motion whenin con- A The cushions of these conventional lug straps, or the curved fulcrum surfaces thereof, extend from edge to edge of the straps' at the bend. Experience has proven thatr in lug straps thus formed-a weak place is hadat eachside of the strap where the narrow intermediate portion merges with the wider end portions.

Thisweakness is objectionable especially lin f slightly less width than the strap and of J view of thev fact that the cushion ,extends to the edges of the strap at the bend, causing the picker stickto come into constant active contact with 'the edges of the cushion so as to mutilate them and soon destroy the usefulness of the strap.

The primary object of the present invention, therefore, is to provide an improved lug strapV of the class mentioned by means of which the vabove* objections are effectively overcome without the aid of objectionable separate pads or facings, thereby insuring better results and longer life of the strap as compared with the straps of conventional form. I preferably accomplish this object by forming the lug strap of uniform width throughout, and by providing the same with an integral internal fulcrum cushion of such depth that the picker stick may not contact or pound the edges of thevstrap at the bend.

The bearing or. impact surface of thc cushion 6 is of the usual convex orcurved` be provided for connecting the supporting loop 12 to the lugstrap for holding the latter in proper relation to the picker stick. v

I iind in practice that the present lug strap gives better results and lasts longer than straps having the bend of less width than the ends and having the cushion ofl the same width as the strap at the bend, as now com-f' j monlymade. y
