This is a division of application Serial No. 82,979, filed June 1, 1936.

The invention relates to improvements in fluidtight tension ring closures for metal packing vessels and has for its object to provide a simplified device of this character affording a reliably tight fit of the ends of the tension ring and the possibility of adjustment thereof.

In the accompanying drawings:

Fig. 10 is a transverse sectional view on the line I0l0 of Fig.7.

On the edge of the vessel a and enclosing the packing b, is located the cover 0 of the vessel, provided with a hollow edge, the tension ring d embracing the cover and edge of the vessel. On the ends of the tension ring are secured the closure parts 6, J.

On the closure part c, of one end of the ring, the tension lever h is pivotally mounted at point g with the extension I, which bears against the edge of the cover 0. The extension I .carries the tightening member 2, which is pivotally mounted at point I. The lever 71. is bent ofi to the thickness of the closure parts e, f, so that the tightening member 2 slides closely over the same. Towards the middle of the cover the tightening member is chamfered in a downward direction over the whole length and the chamfered edge bears tightly against the closure parts e, f. The engagement projection 3, which is provided at the freely projecting end of the-member ,2, and is also made by bending round or turning down the corner, engages selectively in the engaging slots 4 of the closure part 1 and at the same time, owing to its hook-like structure grips under the closure part I in such a way that any pressing downward is prevented. When engaging in the slot 4, selected in accordance with the desired degree of tension, the engaging projection 3 fits into the whole length of the slot. It is thus made difficult for the tightening member 2 to be swung down and thus the tension lever 71. is effectively secured against snapping back into the open position. The holes 5 are intended to receive a sealin wire, (Fig. 3). Fig. 3 also shows that in the case of both the largest as well as in the smallest tension position the axes of pull .ra: and z-z form an acute angle with the tangent y y 0n the side opposite the tension lever h. Fig. 4 shows a partial side view of the tightening member 2, to an enlarged scale, the said member being bent at the portion 6 disposed towards the center of the cover, in such a way that it also embraces the closure parts e, i, from below. As a result the stability of the closure is increased to a further extent.- Fig. 5 shows the tension ring closure according to the invention in the open condition. The surface of the tension member 2 is provided with advertising matter.

Inthe modification shown in Figs. 6 to 10, the

tensioning of the closure is effected by swinging the lever h towards the edge of the cover, in

which case through the bearing of the widened part I of the lever 71. against the edge of the cover, one end of the ring isdrawn toward the vessel edge. At the same time the closure part I isgripped by the tightening member 2 and the other end of the ring is also tightened. The axes of pull xx and ZZ, which correspond to the smallest and largest tension position of the tightening member 2, form an acute angle with the tangent 11-21. applied to the junction point of the ring, in the same manner as described previously, the apex of this angle lying opposite the tension lever.

The closure parts e and f are provided with the longitudinal eyes 1 and 8 arranged towards the middle of the cover and through which the securing pin 9 is inserted in the closed position. The longitudinal eye 8 of the closure part c is open at the side towards the edge of the cover,

so that when the lever 71. swings into the open position the limiting part III of the tension lever projects into the open side of the longitudinal eye 8 (Fig. 9). On the other hand, the part III, when the securing pin 9 is inserted, presses against the latter, so that it is not possible to open the closure (Fig. 10). The projecting end the sealing wire or the end, if the pin consists the ring is contracted, and means for contracting the ring, including a lugat each end of the ring, directed inwardly toward the center of the cover,

a lever pivoted to one lug, a projection on the 1 lever between the inner cover edge and the pivtotal point of the lever and adapted to bear against the cover edge so as to draw the end of the ring against the outer edge of the cover,

means pivoted to the lever and engaging with the second lug for enabling the two ends of t e ring to b drawn together by means of the lev r,

the axis of said means in the closed position intersecting the tangent to the ring at the ju tion point of its two ends in an acute angle on the side of the junction point removed from the -'lever, an eye on each of the lugs and a .pin adapted tobe passed through the eyes in the closed position, the eye on the lug which carries the lever having a recess and the lever having a flat edge which bears against the pin through the recess in the closed position and which can swing into the recess when the pin is withdrawn.
