UNITED STATES PATENT OFFICE.

SEWABD 1B. MERRY, OF BERKELEY, CALIFORNIA ASSIGNOR TO THE REPUBLIC STEEL PAGKAGE COMPANY, OF RICHMOND, CALIFORNIA, A CORPORATION OF CALIFOR- STEEL-BARREL TOP AND COVER THEREFOR.

Application filed November 8, 1925. Serial No. 66,488.

My invention relates to barrels or other containers, and it has special reference to tops and covers for barrels made of sheet steel or other strong sheet material adapted 6 to withstand the rough usage to which such barrels are subjected in service and shipment. I

, For steel-barrels, in which various materials are shipped, it is customary to provide covers that are secured to the tops of the barrels, with a number of bolts, but, sincea considerable amount of time is consumed by this method both, in sealing the containers for shipment and in opening them, cov- 16 ers have been provided/for the purpose of guick application and removal. It has been ound in practice, however, that, as a result of the bumps and hard knocks the containers receive in transportation, the tops of the containers become so dented that, when the covers are reapplied, a satisfactory seal cannot be effected, and that therefore the containers must go through a renewing process in order to be usable, or otherwise be entirely discarded.

The principal object of. my invention is to construct a top and a cover therefor so that the cover, when it has been placed in position and is partially turned on the top, will effect a perfect seal therewith, irrespeetive of'the dents that may be in the top.

Another object is to make it possible for the barreland its topto be made of light and consequently cheaper sheet material than heretofore used, as the stiff cover of my invention can have sufiicient power applied thereto so as to draw the thinner barrel top to it.

Another object is to construct a top and a cover therefor so that a turning movement in one direction of the cover, unless positively causing a tight junction between the top and the cover, will first be possible without further tightening and,,1f continued, will release the cover from the top in order to make the 0 orator aware of the need of a thicker gas st for efiecting the seal.

In the drawings, which illustrate my invention,

Figure 1 is a fragmental mid-sectional elevation of a barrel, with the cover and the gasket in the barrel top partly in section;

'18 of the flanges 1 Fig. 2 is a side elevation of the cover and a part of the top, as viewed from the right in Fig. 1, the top being in section;

Fig. 3'is a'broken bottom plan of the barrel top of Fig. 1 with the cover therein placed in the initial position for turning to secure it to the barrel top, part of the cover and part of the handle for the cover bein broken awa in order to show clearly the anges and t e slots at the opening in the top;

Fig. 4 is a fragmental, sectional elevation of the barrel top of'Fig. l with the cover removed;

Fig. 5 is a top plan of part of the barrel top with the cover therein and turned to securing position, part of the cover' being broken away to clearly show the slots and spaced flanges at the edge of the openings; an a h Fig. 6 is' a side elevation of Fig. 5, showingto advantage the depending flanges in engagement with the rejections on the cylindricalportion of t e cover.

In the preferred embodiment of my invention, a barrel or container 10, which is preferably made of steel or some other suitable, sheet material, has a top 11 joined thereto as by plies 12, and has therein a circular opening 15. In the edge of the opening are slots 16 spaced equidistantly from one another, and integral with the said top are flanges 17 each of which extends between two successive slots and into the barrel. Each of the flanges 17 has a sloping edge 18, which terminates uninterruptedly in a portion 19 virtually parallel with the plane ofthe top 11.

' For the top '11, I provide a cover 20 preferably of stronger material than the said top, and which cover has a cylindrical portion 21 adapted to slip within the opening 15, and an annular flange 22 integral with the cylindrical portion and adapted to bear on the top when secured-thereto. Formedintegral with the cylindrical ortion 21 are projections 23, which pre erably have slightly sloping sides corresponding with the edges The projections are s aced apart corresponding with the spaced s ots 16 and the flanges 17, so that they are adapted to be inserted through the slots for An annular depression 26 in the flange, anda corresponding annular depression 27 in the top may be formed for drawing the gasket thereinto to seal the joint. By means of a handle 28, secured in any suitable manner to the cover, the attachment thereof to the barrcl top, or the detachment therefrom is easily accomplished.

The projections 23 ride unrestrictedly upon the flanges 17, so that the operator is always aware \vhen'a tight joint is effected. If the gasket 25 is of insufficient thickness to assure a tight 'joint, the projections simply ride fromv the sloping edges 18 onto the straight edges 19 and off, thereby warning the operator that a further tightening cannot be effected and a thicker gasket mustbe provided to assure a perfect seal.

It is thus seen that my invention has a decided advantage over covers provided with lugs which are adapted to ride in grooves, which limit the rotation of the cover to the length of the grooves, and in the useof such covers it is thus often impossible to determine whether a tight seal is effected or not.

A further disadvantage 'in the use of such covers is that, if the container tops have dents or bulges therein, the lugs are thereby prevented from entering the rooves, thus making the containers unusua le for shipment until difiicult repairs are made.

Having thus illustrated and described the preferred embodiment of my invention, I wish it understood that slight-changes may be made, when practice suggests, that come within the spirit and scope of the appended claim.

I claim:

In a barrel, of the like, formed of sheet material and'havin an opening in its top; a plurality of flanges spaced apart from one another and extending into the barrel at said opening; each of said flanges having a sloping edge terminating uninterruptedly in a portion virtually parallel with the plane of said top; a cover having a cylindrical portion adapted 'to fit within said opening, and an annular flange integral with the cylindrical portion and adapted to bear on the top of said barrel; and inclined projections integral with the cylindrical portion. and adapted to be inserted between said spaced flanges and to ride upon the sloping edges thereof for fastening the cover to the barrel by a partial turn of said cover.

In testimony whereof I affix my signature.

SEWARD B. MERRY.
