W. LOCKHART RECEPTACL Feb. 15, 1938.
E AND CLOSURE Filed May 2, 1935 2 Sheets-Sheet 1 Q, ATTORNEY-Q Patented Feb. 15, 1938 UNITED STATES PATENT OFFICE RE CEP'IACLE AND CLOSURE William Lockhart, Cleveland, Ohio, assignor to Cornell Securities Corporation, Cleveland,
7 Claims.
My invention is an improvement in metallic receptacles and closures therefor and relates more particularly to a device for removably clamping the cover or closure on the receptacle in fluid tight sealed relation.
One of the objects of my invention is the provision of a split clamping ring having means for expanding or contracting the ring, the said means including a link and lever mechanism connecting the ends of the ring whereby the ring may-be contracted to exert a closing pressure on the cover to fix it in place on the receptacle and subsequently to seal the cover by additional pressure in fluid tight sealed. relation to the receptacle.
Another object is a ring closing mechanism including a compound link and lever connection between the ends of thering to apply successive closing and clamping pressures to the cover.
A further object is to increase the ease of operating such devices by providing a primary operating lever and link connection between the ring ends, and a supplemental operating lever pivoted to the primary lever and having a driving connection with said link to further contract the ring to press the cover into fluid tight sealed relation with the open end of the receptacle.
A still further object is to construct a device of the above named character economically.
Other objects and advantages of my invention will become more apparent from the following description of two embodiments of the invention, reference being made to the accompanying drawings in which like reference characters are employed to designate like parts throughout the same.

Figure 12 shows the positions of the links and levers when the ring is expanded.
I will refer first to Figures 1 to '7 inclusive, which are illustrative of one embodiment of my invention. The receptacle or container such as a metal barrel, shipping drum or the like is indicated at l. The upper open end of the container is formed with a peripheral bead 2. A cover 3 comprising a cupped or depressed head, having a peripheral upwardly and outwardly extending flange 4, is supported by the bead 2 in such a manner that the cupped portion of the head or cover may be telescoped for a short distance 30 within the open end of the drum, as illustrated in Figure 2. It will be noted that a portion of the flange 4 is of substantially arcuate cross section to conform with the approximate curvature of the upper surface of the bead. A packing 5 35 consisting of an annulus of any suitable packing material, such as flexible rubber tubing or cork, is interposed between the flange 4 and the bead 2.
According to the present invention, I have provided an improved means for removably securing the cover on the drum or receptacle to effect a fluid tight seal therebetween by exerting a substantially uniform and firm pressure along the cover flange and bead in a direction substantially parallel to the longitudinal axis of the drum.
Such means preferably includes a transversely split, channeled clamping ring 6 of substantially U-shaped cross section and which is capable of being expanded and contracted by suitable means. In the form illustrated the upper and lower flange 50 and bead engaging walls respectively of the ring converge slightly toward the outer diameter of the ring and engage the cover flange and bead of the container to press the same together tightly when the ring is contracted. However, it is to be understood that the ring and receptacle open end may be so designed that the cover will be pressed into a tight seal with a shoulder formed at the receptacle open end when the ring is expanded. That is, instead of the receptacle being formed with a rolled bead 2, the open end may be formed with an annular shoulder and an annular channel for receiving an expander type ring, a packing ring and the cover.
By contracting the type of clamping ring herein illustrated, the cover flange will be pressed tightly against the packing 5 and the supporting bead 2 under a substantially vertical pressure.
In further carrying out my invention I have provided means connecting the ends of the split ring for contracting and/or expanding the ring as in locking the cover in place or in removing the same. Such means includes a link and lever connection and in describing first one embodiment thereof I will refer to- Figures 1 to 7 inclusive of the drawings.
The ends of the ring defining the split are provided with a lug or bracket 1 and 8 extending inwardly of the ring, and welded thereto. These lugs also provide reinforcement for the ring ends since it will be seen in Figure 5 that they extend also transversely around the channel as at 9.
An operating lever I is pivotally connected at II with the lug I and is provided with an elongated slot I2 intermediate its ends for purposes which will be more fully described hereinafter. A link I3 which has pivotal connection at one end with the lug 8 as at I4 isconnected at its other end with the lever I 0 by means of a pinor stud I5 passing through and slidably operable in the slot I2. It will thus be seen that by means of the link and lever connection I3 and II) the ring may be contracted and expanded easily. When contracting the ring the lever is moved toward the ring circumference or to the left as shown in Figure 3. During such movement the pinI5 will move to the lower end of the slot I2 (Figure 6) and abut the end wall thereof to complete the driving connection. Such contraction of the ring, however, may be sufficient to clamp the cover in place upon the open end of the receptacle as in shipping the receptacles empty, but it may not be sufiicient to press the cover and receptacle end together tightly enough to provide a fluid tight seal therebetween. A tight seal of this character is highly desirable in shipping or storing receptacles containing food products, oil or other materials. By means of my invention it is possible to provide such a seal by contracting the ring beyond the degree determined by the link and lever I3 and II).
To this end I have provided a supplemental or take up connection comprising a supplemental lever I6 pivoted at I! to the lever Ill and having a driving connection with the link I3 by means of a short supplemental link I 8; The link I8 is pivotally connected with the lever, I6 at one end as at I9 and with the link I3 at its other end by means of the pin or rivet I5 operating in the slot I2.
Thus it will be seen that, by operating the supplemental lever I6 to the left in Figure 6 to the position in Figure 3 a further contraction of the ring takes place through the driving connection I6, I8 and I3, and the pin I5 will travel toward the upper or other end of the slot I2.
In expanding the ring to remove the cover 3 from the receptacle, the levers I8 and I6 may be oppositely swung independently of each other or simultaneously and when it is desired to fully expand the ring the lever I 8 may be swung further to the right than indicated in Figure 6. In such event the pin I5 will abut the wall defining the lower end of the slot.
I have provided a retainer 20 for the outer ends of the levers I I] and IE to hold them in ring contracted position as shown in Figures 3 and 4.
Referring now more particularly to Figures 8 to 12 inclusive, I have illustrated a second embodiment of my invention which is similar generally to that form described above, but which differs in its applicability in use.
In this present form, I have avoided the use of lugs on the ring ends by pivotally connecting an end of the lever 2I directly with the reinforced end of the ring on its upper surface at 22. The link 23 is pivotally connected with the other ring end at 24 and with the lever by means of the pin 25 operating in the slot 26 of the lever 2|. In this modification it will be noted the ring contracting and/or expanding means is disposed outside the inner circumference of the ring and lies and operates in a plane parallel to and slightly above the transverse plane through the uppermost portion of the ring. The operating levers may thus be swung outwardly of the ring as indicated in Figure 12. This arrangement is more convenient under some conditions and gives the operator more hand room in operating the same.
The link and lever 23 and 2! respectfully are employed to contract the ring initially and such degree of contraction may be sufficient in shipping the drums empty. But to' obtain an even greater degree of contraction, I have provided a supplemental link and lever 21 and 28 respectively similar to the corresponding parts I 6 and I8 shown in Figures 1 to 7 inclusive.
The operation of this form of the invention is similar to that of the form previously described, except that the levers swing outwardly of the ring circumference to contract and expand the ring. A suitable retainer 32 is provided to receive and hold the handle ends of the levers 2I and 28 when they are in the position shown in Figure 8.
In operating either form of the invention it will be understood that it is preferable to operate the primary lever I 0 or 2I first to initially contract the ring, and then subsequently operate the supplemental lever I6 or 28 increase the closing pressure on the cover. In this manner, a fluid tight seal is easily obtained with little effort on the part of the operator.
The devices may also be operated by swinging the respective levers I0 and E6 or 2| and 28 simultaneously and thereby fully contract the ring in one operation, but this method will require more effort and the closing forces will not be as uniformly distributed around the extent of the ring.
In allowing the ring to expand, as in removing the cover from the receptacle, it is most desirable to first release the lever IE or 28 and subsequently the lever II] or 2I.
It will be seen from the above description that I have invented a device for removably clamping covers on metallic receptacles in fluid tight sealed relation, which permits first a contraction of the ring to lock the cover in place on the receptacle and which is provided with supplemental means for effecting a further and final contraction of the ring to produce the desired seal.
I tracted, and means for contracting the ring in- While I have described the illustrated embodiments of my invention in some particularity, obviously many others will readily occur to those skilled in this art, and I do not, therefore, limit myself to the precise details shown and described but claim as my invention all embodiments, variations and modifications thereof coming Within the scope of the appended claims.
