Specification of Letters Patent.

Patented May 25, 1909.

, [Application led February 10, 1908. Serial No. 415,078.

De it rvknown that I, SWAN TEvANDER, a clti'zen of theL United States, residing in Toledo, inthe countyof Lucas and State of y Ohio,`have invented ya new and useful Improvementin Bail-Ears, of which the follow- I ing is a specification;

My invention relates to improvements in lbail ears for sheet metal cans or vessels. i0

The object of my invention is to provide a bail'ear of a simpleand efiicient construction, which may be cheaply manufactured u' and readily applied and securely attached to the top,fbreasts or other parts of the sheet metal cans or vessels.

My invention consists in the means I employ to practically accomplish this object ork result asyherein shown and described.

In the accompanying drawing forming a part yof .this specification, Figure l is a side elevation of ka sheet kmetal can provided with my invention. Fig; 2 is an enlarged detail section on liney 2 2 of Fig. l. Fig. 3 is a section on lineS-Bof Fig; 2. Fig. 4 is a detail view ofthe bail ear. Fig. 5 is a detail plan view of one of the yattaching washers and Fig. 6 is adetailsection showing the parts l, after they are assembled but before they are forced vsnugly togetherv reparatory to the galvanizing, sweating, sodering or other opn erationl Fig. 7 illustrates a modification.

In the drawing, A represents a sheet metal canfor vessel having a dome shaped top or breast Bf furnished with slots b through Whichthe ybail ear is inserted, and C the bail. D D1 are washers, one tting inside and one `f outside the breast or other part of the can to which thebail ear is to be attached, and each furnished with a slot d through which the bail ear F is inserted. The bail ear F yhas at its inner end `shoulders f tok engage the 4inner washer,r and in order kto cause the bail ear f when inserted through the washers D D1 and thebreast ory part of the can to which it is to be a )plied to hold or clamp these parts snugly together so `that ythey may be all firinly united together y by the subsequent galvanizing operation,sweating operation or soldering'operation, as the case may be.

I'prefer to provide the upper washer with inclinedlips d1 adjacentto the slot d, which, when the parts are .snugly compressed together, are caused tofkpinch and forcibly grip the shankportionflof the bail ear and thus snugly and rigidly clamp it in close contact with the breast of the vessel and all the parts in close contact with' each other pending the soldering or galvanizing operation. These gripping lips d1 on the outer washer when the parts are firmly compressed together by the assembling dies tend to straighten out, as illustrated in Fig. 3, and thus in effect narrow the slot in the outer washer through which the shank of the bail ear extends.

The gripping and holding action of the inclined lips d1 on the fiat shank portion f1 of the washer D will be readily understood from Figs. 3, 5 and 6 of the drawing, Figs. 5 and 6 showing the inclined lips d1 before the parts are forcibly pressed together and the inclined lips d1 straightened out so as to pinch the flat shant f1 between them yby a kind of toggle action, as shown in Fig. 3, where all ofthe v arts are forcibly pressed together and the inc ined lips d1 straightened or partially straightened out.

In the modification illustrated in Fig. 7, the upper part of the flat shank f1 above the outside washer D is illustrated as being slightly upset so as to form shoulders at the narrow edges of said shank f1 to engage the outer washer D, and thus hold the parts D, D1, B and F all in close snug engagement with each other so that they will pro erly fusibly unite when subjected to the ga vaniZing, sweating or soldering operation, and thus form a liquid tight Closure at the bail ears. In this Fig. 7 modification, the inclined lips d 1 on the washerD may be omitted.

I claim:-

1. The combination with a sheet metal vessel having a breast'furnished with slots through the same, of slotted washers fitting inside and outside said breast, and bail ears having flat shank portions inserted through the slots of said breast and of said inside and outside washers, and having shoulders engaging the inside washers the outer washer having inclined gripping lips engaging the op osite fiat faces of said bail ear shanks to hold said parts in snug engagement with each other, said parts being all fusibly united together, substantially as specified.

2. The combination with a sheet metal vessel having a breast furnished with slots through the same, of slotted washers fitting the slots of said breast and oi' the inside and outside Washers, and having shoulders engaging the inside Washers, said parts being all fusibly united together, and the outer Washers having gripping devices engaging the at 'faces of the shank portions of the bail ears to hold the parts in assembled position, substantially as specified.

3. A bail ear furnished With a shoulder, and a flat shank portion adapted to be in serted through a slot of a vessel and inner and outer slotted Washers through which the shank of the bail ear passes said outer Washer and said flat shank having interengaging devices to hold said parts in snug engagement,

and said arts being all fusibly united together, su stantially as specified.

4. A bail ear having a flat shank, inner and outer Washers through which the shank of the bail ear is inserted7 said bail ear being provided with a shoulder engaging the inner Washer, and the outer Washer having gripping lips to engage the shank of the bail ear and clamp and hold the Washers in place substantially as specied.
