r ti n FOR" SPOUT CLOSURES william udnllebus, Chicago,1ll., assignor to The .-Protectseal Gompany, Chicago, 111., a. corpo- 'A plicat o neith r-23, 1947, Serial No. 781,545 ,.,s.o1aim s.- (01.222473) a This invention relates to operating mechanism for spout closures of cans, andits principal object is .to provide a spring actuated-closure for the spout, of which the spring tightlyseats the clo- "sure on the spout, but its force is overcome somewhat when the closure operating means has been 'fcombination of parts hereinafter fully described and more definitely :claims. l.

The invention is clearly illustrated hr the accompanying drawing, in'whichp v Fig. 1 is a plan of a can equippediwith a spout pointed .out in the appended closure operating mechanismembodyinga simple I 5 dorm of. the present invention; r f Fig. 2 is a side elevation thereof with thepan Jpartly :broken' away andipartly brokeniout to show :a flame. arrester that is located'within the can; i .Fig. .3 is a cross section taken on the line3'-3 :aof Fig. 2; and 1 V s-...:Fig. 4 is axdetail section-taken on .line "4-1 of Fig.2. U V Referring to said drawing which is merely'illus- 'trative of one embodiment of :the iinventiom the referencecharacter 5 designates a canof .conventional form having a dome-shaped'top- '6, from which projects a spout 1, through which the can may be filled, and from which the contents may be poured out. The spout is welded orotherwise secured to the can top 6, and fromithe lower end of the spout leads 'aiifiame arr'ester 8, as is customary for cans handling hazardous liquids.

Riveted, welded or otherwise secured to the "can top is the base 9of a handleJfl whicheomprises the base, and two upright 'legsijl'l: connected at their upper ends by a handle grip l2. Lugs l3 projecttoward the spout from the legs H and support a closure operating lever ll'ip'ivotally connected to the lugs "ll-as by rivets l li or --their equivalents. The ends =-or the arms l lb -of "the lever-are connected by a 'bar 16, fofin'edinte- ,Pivotally mounted on a pair of ears [9, weldd orotherwise secured to the spout, is a closure carrying member zfl which carriesthe closure .2 I. If: desired, the closure carrying member may he inthe form of a metal stamping, or it may be constructed of cast metal. The closure carrying -me'mber is of L-shape and is generally U-shaped in cross:section. .Itslonger arm 22 has a domeshaped end23, in which is .pivotally mounted, as by aicotter pin 24, a stud 25 to which the closure 21 1 is secured. The closure may comprise a Ilangeddisc-like backing 26, in which is held a :gas treated washer 27, a disc 29 which bears against the washer and. a screw 28 which extends through the disc and washer and is threaded in the stud and seats the washer'on the backing 26.

The other arms 22a of the closure carrying member are pivotally mounted upon the ears 19 as by a headed pin 30, which extends through the arms 22a. and through the cars 19. A spring 31 having two coils that surround the pin 30 and terminate in arms 33, 33a. that bear respectively against the side of the spout and against the lower edge of the wall 20 of the closure carrying member functions to tightly hold the closure in its closed position on the spout.

A pair of links 34 connect the lugs H of the lever M with the closure carrying member 20 as at 35. The closure actuating lever is in the nature of the lever of the first order with the links 34 connected to the shorter arms lb of the lever.

' The lever I4 and links providea toggle joint, andwhen the lever is moved to the position seen in Fig. 3, the pivot connections between the lugs Fl -oi the lever and the links 34 approach'the dead "center between the pivot l5 of the lever and'the pivot connections 35 between the links and closure carrying member, giving the lever an enormous mechanical advantage against the spring. Toactuate the closure operating mechanism,
