,3 Claims. (01. 220-61) The invention relates to means for securing in position the split ring or band arranged to retain the cover in sealed or other position over the opening in metal receptacles.
An object of the invention is to provide a means for fastening the ring in position, which will both provide for retaining the ring in tight engagement with the cover and receptacle so as to insure an effective seal therebetween and afford a locking of the ring in position in amanner preventing release of the ring without detection.
Another object of the invention is to provide a closure ring with fastening means, which will have no bulges or other protrusions interfering with the compact storing of the closed receptacles or the ready rolling of the receptacles on their sides.
A further object of the invention is to utilize for clamping the ends of the ring, a means which does not require any special constructionof the such ends. 7
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which'is illustrated in the drawing accompanying and forming part' of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forthin the claims.
Referring to said drawing: Fi ure 1 is a plan view of a steel drum and cove'r sealed and secured together with the clamping ring of my invention.
Figure 2 is an enlargedfragmentary view similar to Figure 1.
Figure 3 is a fragmentary side'view of the parts shown in Figure 2.
Figure 4 is a sectional view of the parts taken 'on theline 4-4 of Figure 3.
Figure 5 is a side view similar to Figure 3, but showing a modified form of the ring. Figure 6 is a vertical sectional view taken on the line 6--'6 of Figure 5.
Figure 7 is a view similar to Fig. 5,'but showing a stillfurther modification.
The ring 2 of my inventionis of the metal type arranged for use as here shown with a drum or other metal receptacle 3 having an out-turned rolled edge or head 4 at, the rim of its opening 6 and with which is associated a cover I having a flanged periphery 8 arranged to fit over the head 4. There is usually provided within the flanged periphery of the cover, a gasket 9,
and the retention of the flange on the bead, so as to secure the cover to the receptacle and at the same time form a sealed joint therebetween,
is effected by drawing the ring tightly about the flange and bead, the ring as will be clear being formed concave at its inner side and arranged to simultaneously engage the complementary shaped portions of the flange and bead so that on contraction of the ring the flange and head will be drawn together.
The ring as here illustrated is of the split type and provided with ends I2 and I3 which are arranged to overlap each other when the ring is operatively disposed about the receptacle. ,Preferably the ring ends are reduced in width at opposite sides and formed flat in contrast to the curved cross section of the main body portion of the ring. For securing the ends together in overlapping relation when the ring is tightly contracted about the cover-flange and receptacle- 'bead, I use a channel shaped clamp M which is positioned over theends with the closed side outwardly. To hold the clamp in placeand lock the ends together, the former is crimped at the top and bottom after being positioned on the ring and while the ring is contracted. Preferably the indentures l6 formed in the clamp by the crimping aforesaid are of such depth as to produce relatively deep corresponding depressions H in each of the opposite side edges of both ring ends.
In order to permit the application of the clamp to the ring including the forming of the indentures l6 therein, without interference with the adjacent surface of the cover and receptacle, there is formed preferably on'the cover flange 8, a pair of bosses l8 spaced apart so as to permit the clamp to be positioned well in between them. The bosses are arranged to be engaged.
by the diiferent ring ends, and thereby serve at all times to keep such ends as well as the clamp in spaced relation to the adjacent portion of the cover-flange and receptacle.
It will be seen from Figure 1 that the portion of the ring comprising the overlapping ends thereof constitute but a relatively small segment of the ring, and therefore when the ring is in operative position it will serve to force the flange and bead together at practically all points of in,- terengagement thereof. In this connection it should also be noted that since the ring bears forcefully against the bosses, even at this area the ring acts to press the cover-flange against thebead.
Y is a band or wire 34 whose An important advantage derived from the use of the type or clamping means shown is that while release thereof may be readily accomplished when purposely efiected, replacement of the clamping member cannot ordinarily fected without such tampering being readily evident on subsequent inspection. The application of the ring and clamp requires special tools and therefore unless a person e fiecting such re-' moval and replacement is in possession of such tools he cannot replace the parts in a manner leaving the owner in ignorance of the unauthorized removal of the ring and the possible tampering with the receptacle contents.
In Figures and 6 I have shown a somewhat modified form of the means for keeping the ring in contracted state about the cover and receptacle. As here shown the ring 215 formed along the under edge thereof with an extension 3! which provides a groove 32 opening outwardly or in other words disposed reversely of the concavity defined by the flange and bead engaging portion 33 of the ring. The groove '32 is substantially coextensive peripherally with the ring portion 33 and is positioned so as to underlie the receptacle bead when the ring is applied thereto. Arranged to seat within the groove 32 v ends 36 may be twisted or otherwise put together hold the ring in contracted form. Preferably the twisted or free ends of the wire are arranged for positioning at the free and somewhat reduced ends 31 of the ring.
In Figure '7- a clamping member 38 is used to secure the ends of the wire 34' in a manner simibe efin order to draw and m to that m which the clamp it engages the ends I! and I3 of the first embodiment.
I claim:
1. A. clamping ring for securing together a receptacle and a cover therefor, comprising an annularbody 'portion having a concave inner side for simultaneously engaging the periphery of said cover and the rim of said receptacle and provided with free end portions arranged to overlap one another, a clamping member embracing the overlapping erids of said ring and arranged to lock said ends against relative movement, and lugs on said cover engageable with said ends at opposite ends of said clamping member to hold the latter spaced from said cover.
2. A clamping ring for securing together a receptacle and a cover therefor, comprising an annular body portion having a concave inner side for simultaneously engaging the periphery of said cover and the rim or said receptacle and provided with free end portions arranged to overlap one another, a clamping member embracing the overlapping ends of said ring. and arranged to' lock said ends against relative movement, and a protuberance formed integral with said cover engageable with said ends to retain same in spaced relation to said cover and receptacle.
3. The combination of a receptacle, a cover therefore, a ring extending around said receptacle and cover for clamping the same together and having end portions extendable into opposed connected position for securing the ring in place, said cover being formed to space said ring end portions transversely from said receptacle and cover.
