17 Claims.

This invention relates to a ,closure for barrels and more particularly to closure means associated with the removable heads of steel drums such as are used in shipping various materials. Steel drums, such as those to which the present invention relates, are used but once for shipping materials andcannot be used a second time. It is therefore apparent that" one of the principal objects .in inventions of this character is to reduce the cost of the barrel, head and closure means to a minimum.

A further object is to provide-a barrel which is adapted for the transportation of materials which are injured by moisture. It is therefore another object of the present invention to provide a reliable and effective seal between the barrel head and the barrel which insures both against leakage of material from the barrel and also against the entrance of moisture or other contaminating agents.

- A further object is to provide sucha barrel and closure which is strong and durable and which will withstand the rough handling to which barreled goods are subjected in transit.

Another object isto provide a closure for a barrel which can be quickly and easily applied. to a barrel and sealed and latched in position after the barrel is filled and ready for transit and can be as quickly released and the closure opened when the barrel arrives at its destination and its contents are to be emptied. C

A further objeetis to provide a closure which insures that the barrel head is firmly heldi'n engagement with the barrel throughout its diameter so that there is no'side at which .leakage is liable to occur.

Another purpose is to provide means for sealing the barrel closure by means of the usual fering or adulterating of the contents of the barrel it is immediately detectable and the car-.

rier is enabled to immediately determine the exact place at which the pilfering occurred, thereby increasing the chances of apprehendingthe parties guilty of the pilfering. Y

Another object is to provide-a split'ring closure for securing the head on the barrel in which the ends of thesplit ring are drawn together. about the. barrel and its head by a link which provides a powerful leverage in contracting'the ring. i Another aim of the present invention is to provide, in combination with such linkage, means for locking the linkage in its closed position and to provide, in combination with such locking I wire and lead seals so that, if there is any pll- 'means, a seal for preventing unlocking of the locking means without breaking the seal.

Another object -of the present invention is to provide, in combination with such a toggle linkage, a lock therefor which is adapted to be sealed by a lead and wire seal, the wire of the seal passing through the lock in such manner that there is no danger of accidentally shearing the wire and destroying the seal.

Fig. 16. a Referring to Figs. 1-5, the numeral 20 represents the usual steel drum or barrel, such as are .used in transporting materials and which are generally provided with a, permanent closure or head (not shown) at one end while their upper projectinwardly from the split ring 26.

ends are left open to receive the contents with which they are packed, this open end being subsequently closed by a removable barrel head 2E. The open upper end of the barrel is specially formed to receive the removable head 2i and for this purpose is beaded outwardly as indicated at 22. The removable barrel head is also made of sheet metal and is formed at its edge with an upstanding rim 23. The upper edge of this rim 23 is flanged outwardly, as indicated at 2 and this flange 2 1 is rounded to fit over the bead of the barrel. Between this flange 2d of the barrel head and the bead 22 of the barrel a gasket or seal 25 of rubber or other material is placed so that a moisture-proof and dirt-proof seal is provided between the barrel and head during shipping.

In order to fasten the barrel head in its closed position and in order to press the barrel head firmly against the bead 22 of the barrel and effect a reliable seal, a split ring 26 is placed around the flange and bead of the barrel head and barrel and the ends of this split ring are drawn tightly into engagement with the barrel and head by means of a toggle linkage, indicated generally at 27. The split ring 26 is of inwardly opening channel form and is rounded in cross section, the upper rim of this split ring wedging against the upper face of the flange 25 of the barrel'head and the lower rim of this split ring wedging against the under face of the bead 22 of the barrel.

It has been found that where a tight and'perfeet seal is required between the barrel and the head it is desirable to have means for drawing the split ring into firm engagement with the barrel and the head in addition to the toggle linkage 21.. Thus, regardless of how much force may be exerted in drawing the ends of the split ring 26 together the side of the split ring opposite from the split cannot be drawn into the same tight engagement with the barrel and the head as the ends of the ring and this opposite side will be loose to a greater or less degree. This is due to the fact that the friction between the split ring and the barrel shell and head is so great that the split ring cannot be drawn into uniformly tight engagement with the shell and cover its entire extent through pressure exerted at one point only.

To provide a uniformly tight shell at all points around the periphery of the ring two additional tightening levers 36 are pivoted to ears 3! which These levers 3B are arranged equi-distant from one another and also equi-distant from the ends of the split ring and each of these levers is provided with a cam extension-32, this cam extension engaging a stationary abutment 33 welded or otherwise secured to the top of the barrel head. This abutment is preferably in the form of an L- shaped piece of metal, as best shown in Fig. 6,

- and each abutment is arranged on the side of the lever 3!? remote from the ends of the ring so that upon drawing the levers 38 toward the ends of the ring the cam portion 32 thereof wedges against the abutment 33 and draws the corresponding side of the ring in the direction toward its ends.

Each of the levers 36' is also provided with a hole 34 which is adapted to register with a corresponding hole 35 ofanother ear 36 of the split ring 26 so that when the levers are in latched .position the holes 3% and register and can receive a sealing wire 38, which is threaded through these holes and has its ends joined by the usual lead seal 38.

The toggle linkage 27 comprises a long lever 46 which is pivoted as at M at one end to one of the ends of the split ring 26 and at its center is connected to the other end of the split ring 26 by a link :12. This lever to is of channel form so as to fit around the channel shaped ring 26 and its free end is provided with a downward extension 43 having a hole 64 adapted to receive a sealing wire 38 and lead seal 39. On the upper side of the free end of the lever 89 is also pivoted an L-shaped lock 45, the pivotal connection 46 for this lock extending through the upper leg of this lock and securing it to the upper side of the lever 49. This lock 45 cooperates with a catch 4? which is permanently secured to that end of the split ring 26 to which the ring 52 is connected. This catch comprises a rounding portion 48 which is fitted and secured to the outside of the split ring 26 and an upwardly offset catch portion 69 under which the lock 45 is adapted to swing.

From the foregoing it is apparent that after the levers 30 have been moved to draw the center of the split ring into engagement with the barrel and its head the ends of the split ring are drawn together by swinging the lever l!) downwardly,

this downward movement of the lever forcing the link 42 toward the, pivot M When the lever 30 is forced downwardly to its latched position, shown in Fig. 3, it embraces and conceals the link 412 and the ends of the split ring 26. When the lever 46 is in its closed position, the L-shaped lock 35 can be swung to its locked position under the catch portion 49 of the catch 37. In this position a hole 56; in the lock 45 registers with the hole M in the lever to and a sealing wire 38 can be drawn through these registering holes and the ends of the wire 38 sealed with a lead seal 39 in the usual manner.

In the form'of the invention shown in Figs. 8-15 a difierent form of toggle linkage 21a is provided for drawing the ends of the split ring together and instead of the levers 31) a screw tightening means are provided for drawing the side of the split ring opposite to its ends into firm en agement with the barrel and head. Two of these screw tighteners, indicated generally at 52, are provided, these being equidistant from one another and from the toggle linkage 27a. Each of the tighteners 52 consists of an ear 54 welded or otherwise secured to the ring 26a and projecting inwardly therefrom. A bolt 55 passes through this ear and also through an ear 56 which is welded or otherwise suitably secured to the top? of the barrel head. The ear 5B of each of the auxiliary tighteners 52 is arranged on the side of the ear E l nearest the ends of the ring so that tightening the bolt 55 draws the adjacent part of the ring toward its ends.

The modified form of toggle linkage 210., shown in Figs. 8-15, comprises a lever 51 pivotally secured, as indicated at 58, to one end of the split ring 26a and being formed in cross section to swing down over and to fit around that end of the split ring to which it is secured. A link 59 connects the center portion of the lever 57 with the opposite end of the split ring 28a and this link is formed to fit around and cover the ends of the split ring 26a when the lever 51 is forced down into its latched position. The free end of the lever 5! is provided with a downward extension 6i) having an opening Bl adapted to receive a sealing wire. This lever 5i, at its free end, also carries a lock 62 which is pivoted to the upper side of the lever 51, as indicated at 63,'so that the lock swings horizontally. The free end'of the lock 62, as best shown in Figs. 8, l and 11 is of channel form in cross section and is adapted to. embrace the corresponding part of the split ring 26a. Between this channel shaped end of the lock 62 and its pivotal mounting, this look is pro-.-' vided with a downward extension having a hole 64 which is adapted to register with the hole Si in the lever 51. A sealing wire -38 with a lead seal 39 can be passed through these holes.

It is apparent that with this form of the invention the ends of the locking ring are drawn.

and latched together by swinging the lever 51 downwardly and then swinging the lock 62 horizontally so as to embrace the split ring 26a so as to prevent an accidental return upward movement of the lever 51. The downward movement of the lever, of course, through its toggle link 59 exerts a powerful force in drawing the ends of the split ring 260, together. a

In the form of the invention shown in" Figs. 16-19 a further modified form is shown of the toggle linkage for drawing the ends of the split ring together and latching the ring in its contracted condition about the barrel head and barrel.

As there shown, a lever I0 is pivoted at "H to one end of the splint ring 26b so as to swing horizontally inward. This lever is of L-shaped form in cross section and when swung outwardly fits over the ends of the split ring 26b; At its ex-, treme end this lever is provided with an inwardly projecting ear 12 having a hole 13 adapted to receive the sealing .wire 38. The central portion of this lever 18 is connected by a link M withthe opposite end of-the split ring 26b and to this apposite end is also secured a lock 15. This lock is pivotally secured as at 16 so as to swing verticelly and this lock is of channel form in cross section so that when it is swung down it embraces both the free end of the lever'lO and the split ring 26b so as to prevent an accidental return inward movement of the lever .10. On its inner side this lock is provided with an ear 1! having a hole 18 and this ear is adapted to fit against that side of the ear 12 on the lever Ill which faces the pivot II. The sealing wire 38 passing through the ho es 13 and 18, of course, seals the linkage in its locked condition.

With the form of the invent'on shown in Figs. 16-19 it is apparent that upon swinging the lever Ill outwardly its toggle link 14 is moved so that the'ends of the split ring 261) are drawn together.

When the lever I0 has been drawn to its position in which it s arranged against the side of the split 'ring,'as shown in Fig. 16, the lock 15 can be swung downwardly so as to embrace the free end of the lever 10 and the split ring 26b and prevent the return movement of the lever 10. The sealing wire 38 can then be passed through the registering' openingsin the ears I2 and I1 and the toggle linkage sealed, against pilfering.

From the foregoing it is apparent that the present invention provides a very simple and inexpensive b'arrel head construction in which latch-- ing means between the head and barrel are provided at at least three places, these latching means insuring that the head is tightly pressed against the barrel at all places around its periphery, thereby avoiding leakage of the contents or'contamination of the contents. The invention also provides a construction which is extremely easy to set up and also permits the cover to be quckly and easily removed when it is desired to remove the easily and quickly sealed to render pilfering of the contents of the barrel instantly detectable.
