6 Claims.
My inventionrelates to metallic receptacles and closures therefor. The general object of the invention is to provide simple means for securely but detachably clamping the cover of a metallic receptacle or drum to the rim or circumferential bead with fluid tight eifect.
Other and further objects and advantages of the invention will be understood from the following description considered in connection with the accompanying drawing, in which: 7
Figure 1 is a top plan view of the invention, showing the cover on the receptacle tightly sealed; 7
Figure 2 is a top plan view showing in dotted l lines the position assumed by the clamping link preliminary to clamping operations;
Figure 3 is a fragmentary view of the clamping ring;
Figure 4is a section taken on line fl--t of Figure 1;
Figure 5 is a detail view of the link and cam member; and
Figure 6 is a fragmentary sectional viewtaken on the line 6-6 of Figure 2.
Referring more particularly to the drawing 5 denotes a barrel or drum such as commonly employed for shipping grease, oils and the like. The upper open end of drum 5 is rolled outwardly and downwardly and thence inwardly to provide l a reinforcing bead t for supporting a cover I. This cover is centrally depressed or cupped to seat snugly within the open end of the drum, and is formed with an outwardly and downwardly curved peripheral flange portion 8 partially con- 3 forming to the curvature of and adapted to seat upon the upper portion of head 6. If desirable any suitable form of packing ring, not shown, may be inserted between the bead 6 and flange 0 of the drum'and cover respectively.
l The cover which is readily removable for filling or other purposes is clamped in place by means of a split contractible clamping ring 9 of substantially U-shaped cross section which embraces the head 6 and flange 0 and exerts a uniform clamping pressure thereagainst when contracted. The upper flange engaging wall and the lower bead engaging wall of the ring are This split ring 9 is formed at opposite ends with in- 50 wardly extending lugs l0 and l I, either integrally downwardly at 12 and thence inwardly as at IS in a horizontal plane parallel to but approximately midway between the horizontal planes of the cover I and lug l0.
A lever l4 pivotally connected at its inner end to lug ID by means ofpivot pin I5 is adapted to be sealed against accidental or unauthorized movement when swung to locked position beneath an apertured ear l6 projecting inwardly from the top wall of ring 9, the outer end of the lever'being apertured at H for this purpose. A collar 23 maintains the, lever in slightly spaced relation with respect to the lug N]. A link l8 pivotally connected at one end to the top face of lever It, adjacent the pivotal connection E5 of the latter, by means of a pin l0, carries a pin 20 at its other end which pin 20 is adapted to line position. When pin 20 is seated in the notch 2i, and lever it is moved in a clockwise direction about pivot pin it, to Figure 1 position, the
ends ofclamping ring 9 will be drawn towards each other and the ring will exert a substantially uniform pressure on the flange B and head it in a direction substantially parallel to the axis of the drum ii.
It'will be noted that when the lever it is moved to force the pivot pins 85 and 20 toward each other, there will be a slight tendency to spring the adjacent ends of the ring outwardly due to the leverage or spacing of these pins away from the ends of the ring. Such outward projection of the ends of the ring is somewhat objectionable and in order to draw these ends in more closely to the cover, a cam member or plate 22 is provided for engagement with the inner face of the vertical wall of cover 7, during clamping or closure operations. -This cam plate is pivotally mounted at one end on the lower end of pivot pin it and at its other end is connected to link It by bolt or pin 20, a. spacing collar 24 being employed to provide ample space 25 between the link it and plate 22 for reception and free relative movement of lever it.
The notched end of lug I l is offset as previously explained, to lie in the same horizontal plane occupied by the space 25 between the link and cam member 22 so that pin 20 of link I 8' can be hooked over said notched end and lodged in the notch 2|, as indicated by dotted lines in Figure 2.
. When pin 20 has been completely seated in notch 2| by appropriate manipulation of lever ll, the outer end of curved edge 26 of member 22 contacts the wall of cover 1 adjacent the lug I l, and as the lever is moved to Figure 1 position the entire edge .26 is forced with cam eifect against said wall, thus exerting considerable outward pressure against the cover and serving to draw the endsof the contracting clamping ring inwardly against the flange and bead. The cam member 22 which is approximately the same length as link II, is of suflicient length to substantially span the entire area occupied by the two lugs II and II and also is of such size and shape as to exert considerable lateral pressure against the side wall of the cover, throughout this area, and to cause the ring to be tightly clamped about the beadand flange when lever I4 is moved in a clockwise direction to locked or sealing position.
It will be noted that the link II and cam member 22 are connected through the lever ll, with but one end of the ring a and that the ring can; therefore be readily applied to and as easily removed from the drum, without disturbing the lever connection with the ring. c
Having thus described my invention, what I claim is:
1. The combination with a metallic receptacle having a bead rolled about its open end, and a removable cover for said receptacle having a marginal flange fitting over the said bead, of a split contractible channeled clamping ring having walls engageable'with the flange and bead for pressing the same together when the ring is contracted, inwardly extending lugs adjacent the ends of said ring, a lever for contracting said ring pivoted to one of said lugs, the other of said lugs having a notch therein, a link pivoted to the lever and carrying a pin at its other end for engagement with said notch, and means carried by said link which engages with the adjacent sur-' engages with the adjacent surface of the side.
