Attention is nowdirected t the contour of the fingers, particularly those portions extending forwardly' from the arm I3. As illustrated'in Figs; 1 and 2,; the forwardlyprojectedportionsv of the fingersvgradually reduce in'thicknes's to forward edges 60, vwhich are almost knife-like, the under surfaces of each finger lying in a common horizontal plane, as indicated at El, to

in a plane at right angles to the article upon which it is to'be disposed.

j Attention is further movement of the washer. to the groove26 in the rticle, wherethe resiliency of the washerwill cause it to lie snugly in'thelgroove.

It'is, therefore, apparet that with this as- T sembling tool split'washers may bejeadily and accurately assembled on-articles [with little eflort,

the assembling tool ,requir ingtw main movements on the part of the operator to accomplish this result, one being" the gripping of the tool to bring about movementrofthe arm' I3 relative,

I r to the body to remove the. first washer from the: supply and thenmoye the tool while'in this conmaintain each Washer, while being assembled, I v

latter movement including the movement of the tooli'nto'lregistration with the article and the con- ,ti'nued movement ofithe body-l0, the arm l3 directed to the fact that the inner or adjacent ends of'the fingers are cut away, as at 62, to more easily straddle the magazine rod l1. As

described, the fingers are movable outwardly away: from each other, but springs 64 mounted upon the sides of the armus engagethe'o'uter ends-{ct the fingers toqnorrnally urge them toward each other. I r t 1 -Th'e'tool is conditioned for operation fby -filling the magazin'erod with'a supply of the washers I8, this being made possible by loosening the'set chamberISQand freeof the support 3lM-fIhe washers may be readily disposed on the rod ;|1 over the pointed end 21 thereof, they beingprevented from dropping oif the opposite end'of'th'edition with the first'washer 'already selected, this and the fingers S Z ,whilejthe magazine rod l1 stops with its 'n agement'with the article. causingiunctioning of the fingers to move the selected washer-over the; tapered or enlarging surfacesv 20 'an'd22 hffthe rdd, conditioningthe washer to be'moved" onto the article and continuing this movement until tlie washer'dropsinto theffgroove 5 rod due to'the outwardly flared contour (20 123 thereof; Themagazine rod may again bein serted in place and; there held by the set screw,

During this movement the edges of the fingers will passbetwe'en'the bottom washer, l8 and the remaining washrs on the magazine, 'locating'the washer to be assembled beneath the surfaces 6 l-' of the fingersL Atthis timeg-assumingthat the magazine rod lTis' disposed in engagement with the end of the fuicrum pi n 23and that the fulcrum pin ismounted against mdvemeritfthe" I operatormay'move the body l0 and all other parts movable'therewith, including, the "arm' I3 and 'the' fingers 52, toward the article, causing relative movement ofuthe fingersrand the megazine rod tojmove-the first washer l8 over' the portion IZILftli'e portion 22 and'onto'the article, Duringthis movement ofzthe fingers'v52theywill becaused tohug the rod l1 throughthecombined force 'of the springs" 64; maintaining engagement with theselected .wa'sherIand moving"outwardly dueto the-varying contoursof the portions 20=and- 22; while'xthe split washer is en-' larged equal to or slightly greater than the diameteriofithe article'so as to pass readily thereonas'itileaves the portion 22.
