To all whom it may eminem:

Be i't known that il, SAMUEL C. BOND', resid". ing et Wilmingtom in the eounty of New# castle End State of Del-(tirare, a eitizen of the United States, have invented or discovered cert-ein new und usefulA lmprrrvements in Metalheping Tools, of which improvements the followingl is siiieoitiozrtion.

The invention described herein relates to* certainv improvements in tools for e'lieoting e shaping or oonifinnling` notion on :i )lastic materiel, the tool being especially applicable tfor use in. eeeuringg metiii oeps on hotties.

In general terms th(l invention 'consists of o,

wings as in the coiled Wire, the Wings may be formed of o series of thm plates round or oblong in contour es shown in Fig. 3, 4 and 5.

Inthe ermstruction shown in Fig. 5. the Outer ends of the wings bear against a stationary abutment having suitable seats' therefor. These wings are so Constructed, i. e. with e slight ceinber, that when sulojeoted toend thrust the wings will buckle Or bend. Or shown in Fig. 3 end-fl the wings may he mede rigid. and being arranged aten angle lese tha-n e right angle to the abutment,

`they will when subjected to end thrust tend to shift the el) uti nent which is movable lbut yielding'ly hold ne against movementby springs 3,

l/Vhen, the abutment 2 is shifted around against the springe lj, by pressure on the inner ends; of the wings l., the Outer ends of the wings Vwill move with abutment thereby so ehnngingthe angular position Oi. the Wings 'tiret the inner ends een move rediell'in- :creasing the internal perimeter of the opening 'tormedhy the Winge. As will he see-n by reference to lfig- 25 the lower end. ol" the plunger then the oxterrml dimneter Ol' the cap to be aprilie-1d. The tool consisting of the abutment and rinliitlly :wronged rings, is held within the heu-d by in annular block 4 hn'vingnr n llnriingr internal opening, the sides Oi' Said oiienixrsr` serving` :1.5 guides in applying the een. A czt'nprossing plunger 5 slightly conical und having a diinneter nt its lower end n little greoter thon that oi the oop, isA nrrnngorl inthe houd with its :1.x is in line witl'i tl .i :wie ol1 tho tool. The plunger is lno'ved to open tho tool, when the een ieto he [winced therein lielforo lit-.ing nppliod to the bottle, by?

plunger :1nd within the tubulin extension S oi" the houd. yThe movonwnt ot the plunger into the tool to operv tho sinne is regulated hy my suitnhlo menne, :is `lior exmnplo Yhy n nut t?, screwing on to the stom nud having n hour ing on the tuhulsnj oxtoneion. As the lower' end ol the plunger is conical, the opening of the ,tool can be adjusted according to' thelV diameter of'the cap to 4be applied.

Inorder to su port thecap Within the tool until it is place on the4 bottle, one or more 5 notches a areformed in the side of the plun ger, of a Width approximately equal to the thickness oi-the operative ends of the'wings.' When the plunger is forced into the. tool to spread the same the Wing or Wings opposite. t ese notches orgr/nnves a will notbe orced' out as far as the otlrer'wings and Will'thereiore serve to grip theffcap and; hold it in position in the tool.g i I y Q f In theforin of tool shown in Figs. 1 and-2 the Wings .of the tool are formed by a spirally 1 coiled Wire bentto annular` form. The coils or Wings are caused to assume a position at an angle to the radii of ay circle Whose,center coincides with the axis of the annulus, byforcing a mandrel into. the annulus and then giving it a partialturn, 'thereby giving the coils or Wings aset atanangle to true radial planes. When the tool is openedlby the plunger or a cap on a bottle7 the force exerted v onvthe operative inner portions or ends of thyvings Will tend to cause the coils or Wings td lassume a more' angular position, or a po' sition more nearly tangentialto the perimeter of the cap or plunger. 'This shifting of the coils or Wings places the Wire under torsional strain) which will be'suiiicient to cause theop-v` .erative'portion ofwng or coil to have an effective shaping pressure on the flange of the .ca v
