Feb. 9; 1965 C. A. UNCAPHER ETAL COMBINATION DRUM AND FASTENING LUG Filed June 26, 1962 A FJIL 73% I. 'IIIIIIIIIIIIIIIIII CHAELS.

INVENTOR A .UNCHPHEFZ 2 HA V E. LESHEZ United States Patent York Filed June 26, 1962, Ser. No. 265,448 12 Claims. (Cl. 229--47) This invention relates to fiber drums and to novel means by which covers or closure members may be held closed on such drums.

The invention more particularly deals with a novel fastening lug structure which is attached to the chime of a fiber drum and serves by a snap over engagement to hold a cover or closure member in closed position over a drum end.

The completed drums of the present invention are particularly adapted for the storage and shipment of lard, vegetable shortening and the like. The drum bodies preferably are made from fiber tubing composed of several plies or windings of paperboard. The interior surfaces of the drum bodies are further provided with a lining or coating so as to prevent the absorption of the lard or comparable fill and this not only prevents the drums from taking on an undesirable appearance, but further tends to prevent the lard from oxidizing and becoming rancid.

Drums of this type are provided with a closure member at one end thereof which may be opened for access to the material therein, and later again closed. In holding such a closure or cover on the end of a drum of this type, it has been known to provide swingable members which are fastened to the drum side Wall and which engage the closure member by snap-fit engagement, or the like so as to retain the cover in tight relationship on the end of the drum over which the closure is applied. These fastening lugs of prior art devices have, however, been attached directly through the side wall of the drum and therefore have necessitated a puncturing of the body side Wall. In those cases where lining is already provided on the inner surfaces of the drum body, the direct mounting thereon of a fastening lug which pierces the lining would necessitate a patching of the pierced portions. Also, in those cases where the lining or coating is applied to the inner surfaces of the drum after these lugs have been attached thereto, those areas pierced by the mounting of the fastening lugs must be covered or patched so as to present a smooth surface for either the coating or the lining.

It is, therefore, an object of the invention to provide a fiber drum of the type referred to having a closure member attached at one end thereof, the closure member being held in tight engagement on the drum by means of fastening lugs which are pivotally mounted on the drum side wall Without resort to side wall piercing, thereby avoiding a defacing or weakening of the drum side walls by piercing thereof.

Another object of the invention is to provide a drum having a chime on which are pivotally mounted a plurality of closure fastening lugs each secured in place by a pair of spaced beads having interior recesses for engagement with ears projecting from an end of each lug.

A further object of the invention is to provide a drum having a metal chime turned over one end of the drum and extending part way along a side thereof, pairs of outwardly extending spaced beads being formed from portions of the chime and spaced about its periphery, and each lug being pivotally secured at one end to the outer surface of the drum by a pair of said beads.

A still further object of the invention is to provide a drum having a metal chime turned 0 er one end thereof and extending part way along the side thereof, pairs of outwardly extending spaced beads being formed from portions of the chime and spaced about its periphery, each pair of beads having opposed edges defining openings into interior recesses formed by the beads, a plurality of fastening lugs each being pivotally secured at one end to the outer surface of the drum by engagement with the individual pairs of beads, each lug being of generally strap-lilte configuration and provided with an ear projecting from each side at the pivotally secured end thereof, said projecting ears being engaged in the bead recesses whereby the lug may be swingingly moved to a position overlying a closure member engaged with one end of the drum for snap-fit securing engagement therewith.

Another object of the invention is to provide a cover lug securing arrangement of the character stated wherein the chime is provided with a slot between each cooperating pair of beads and merging at each side thereof with the interior recesses formed by said heads, the lug being pivotally mountable by insertion through said slot.

It is another object of the invention to provide a fastening lug for use with a drum having a metal chime turned over one end thereof, the fastening lug having a generally strap-like configuration, one end of the lug having an ear projecting from each side thereof for engagement with beads formed along the surface of the metal chime, and the other end being provided with a curved snap over closure engagement portion.

It is a still further object of the invention to provide a fastening lug for use with a drum having a metal chime turned over one end thereof, the lug having a generally strap-like configuration, one end of the lug having an ear projecting from each side thereof for engagement with beads formed along the surface of the metal chime, a generally straight lower portion forming a base from which the ears project, which lower portion is connected to an upper generally straight portion and forms an obtuse angle therewith, said lower portion having a reduced lateral extent and being partially bent in ii-section about a centrally disposed longitudinal fold line to contract said ears in lateral spacing so that they will be readily receivable between the beads of a cooperating pair.

A further object of the invention is to provide a novel method of joining a fastening lug to the metal chime of a drum, said method comprising providing the chime with outwardly projected beads presenting opposing recesses, providing the lug at one end with outwardly projecting mounting ears, and presenting the lug ears in pivotal engagement in the ear recesses.

Another object of the invention is the provision of a novel method of joining a fastening lug to the metal chime of av drum, the chime having spaced beads therein providing opposing recesses, and the lug having outwardly projecting mounting ears at one end thereof and being bent into V-shape intermediately of said ears, said method comprising placing the lug with its ears between the bead recesses and flattening the V-shaped lug portion to present the lug ears in pivotal engagement in said recesses.

A still further object of the invention is to provide a novel method of the character stated wherein the chime is provided with an open slot between the beads of each cooperating pair and the beads open through the back of the chime, the presentation of the lug ears in the bead re cesses being by way of insertion of a lug through a chime slot and engagement of the lug ears in the bead recesses through the open backs of the beads.

With the above and other objects in View, as will appear hereinafter, the nature of the invention will be more clearly understood by reference to the following detailed description and the accompanying drawing.

In the drawing:

FIGURE 1 is a fragmentary elevational View of the drum of the present invention with parts broken away for clarity and, in particular, showing one form of means for attaching the fastening lug to the metal chime of the drum.

FIGURE 2 is a fragmentary vertical sectional view of the embodiment shown in FIGURE 1, the section being taken on the line 2-2 of FIGURE 1.

FIGURE 3 is a view similar to FIGURE 1 with parts being broken away for purposes of clarity and showing another embodiment of the fastening lug of the present invention in an intermediate stage of its attachment to the metal chime of the fiber drum, the lug being shown as flattened out in dot and dash lines, with its ears in place in the bead recesses.

FIGURE 4 is a fragmentary vertical sectional View illustrating the embodiment shown in FIGURE 3 with the fastening lug embodiment of FIGURE 3 flattened in final secure pivoted attachment to the metal chime.

FIGURE 5 is a horizontal section taken on the line 5-5 of FIGURE 3.

Referring to the drawing in detail, there is therein shown a drum 5 having a side wall 6 made up of a tube of several plies or convolute windings of paperboard or the like. The interior surfaces of the drum 5 are preferably provided with a coating or lining 7 which is impervious to the products to be carried in the drum, thus to protect the side wall 6 from product absorption in cases where the drum is to be utilized in carrying lard, vegetable shortening, or like fill. Other products may, of course, be contained in the drum d, it being obvious that petroleum jelly, flaked or powdered chemicals and many other materials may be packaged therein.

A cut end edge 8 of the side wall s is covered by or enclosed in a metal chime 9 which is telescoped over the side wall 6, as by turning portions of the chime over the edge 8 and into compression therewith as shown in F1- URE 2. The metal chime 9 extends partially downward along the side wall 6 and forms a metal band around the top of the drum 5. Further associated with the drum 5 is a cover or closure member 10 held in place by a plurality of fastening lugs 11. The cover or closure member It? may be of conventional design normally provided with a strengthening depression or rib 12, an upwardly curved portion or channel 13 for engagement over the metal chime 9, and a downwardly extending side Wall or skirt portion 14 which embraces the upper portion of the chime and terminates in an upwardly turned hem or curl 15.

About the periphery of the chime 9 there are provided a plurality of pairs of spaced beads 16, the beads of each pair being placed in opposition one to another. Each head 16 is formed from an outwardly displaced or projected portion of the metal chime 9 and thus forms an interior recess 17, the recesses provided by each cooperab.

ing pair of the beads 16 opening in opposition one to the other through the opposed cut edges 1% of the beads. The beads 16 and the recesses 17' therein may be formed by a punching operation prior to the placement of the chime on the side wall 6 of the drum, or such beads may be formed along the chime after it has been attached to the drum 5 by cutting spaced longitudinal lines in the chime and outwardly projecting bead forming portions of the chime as by employment of suitable tool means such as a pair of tapered pliers.

It thus becomes apparent that by equipping the fastening lug members 11 with ears 19 which project from either side at one end 20 thereof, a suitable means by which the fastening lugs 11 may be pivotally mounted on the metal chime 9 is provided. In this manner, fastening lugs may be mounted on the chime so as to be swingable from an inactive position in which they do not engage the closure member 19 of the drum 5 to an active, cover securing position such as is illustrated in FIGURES 2 and 4 of the drawing.

It should be noted that the action between the fastening lugs 11 and the closure member 10 may be that of a snap over engagement, as shown in FIGURE 2, or it may be of a mere contact fit which is then later tightened or secured by a downward deformation of the lug end 21 of FIGURE 2 or the lug end 22 of FIGURE 4, it being apparent that either design of the fastening lug end is applicable for both snap-fit and deformation secured engagement over the drum cover. A ring-like deformation or pressing member (not shown) may be utilized in deforming the

ends

21 or 22 of the fastening lugs 11 downwardly into a more secure holding engagement over the closure member 1% when such an operation is to be simultaneously carried out upon the plurality of fastening lugs 111 with which a drum chime is equipped.

Referring now specifically to FIGURES 1 and 2 of the drawing, one embodiment of the present invention is therein disclosed. In this embodiment the metal chime is provided with a slot 23 between each cooperating pair of beads 19 and through which a fastening lug 11 may be threaded prior to the mounting of the metal chime 9 over the end 8 of the fiber side wall 6. Each slot 23 is generally rectangular in form, as shown in FIGURE 1, and extends entirely across between the spaced beads of a cooperating pair, from one cut edge 18 to the opposing cut edge 18. In this manner, the recesses 17 which are formed in the outwardly projected beads 16 merge with or open into the slot 23. This, in effect, forms a continuous opening (17, 23, 1'7) through the metal chime 9.

As was above indicated, the fastening lug 11 is placed or mounted with its end 21 being initially presented through the slot 23 until the ears 19 engage in the bead recesses 17 as shown in FIGURE 1. The chime is then mounted on the side wall 6 of the drum 5. It will be apparent that in this manner the fastening lugs 11 become pivotally secured to the drum in a position along its side wall 6 whereby said lugs can be swung upwardly to engage over and secure a closure member 10 on the drum in the manner previously described. It should be noted further that each fastening lug 11 includes a curved upper portion 24 which conforms to and makes contact with the upwardly curved portion or channel 13 of the closure member 10, a generally straight upper portion 25 downwardly extending therefrom, and a lower portion 26 of generally straight configuration which is dependent from the upper portion 25 and forms an obtuse angle therewith. The

lug portions

25 and 26 may however, form a more or less smooth curve which is outwardly spaced from the side wall 6 if desired. 5

It should be further noted in the embodiments specifically shown in FIGURES 1 and 2 of the drawing that the cars 19 project from either side of the lower portion 20 of each fastening lug 11 and that the general configuration of the fastening lug 11 is strap-like and of equal width along its longitudinal extent except for the projection of the ears 19 as above mentioned.

Referring now to FIGURES 3 and 4 of the drawing, there is therein shown a modified form of fastening lug 11a and in conjunction therewith, another procedure for attaching the fastening lug to the metal chime 9. The fastening lug 11a is constructed similarly to the previously described fastening lug 11 with the exception that its lower generally straight portion 25a which corresponds to portion 26 of fastening lug 11 is of a lesser width. The portion 26a is defined by sides which converge from the full width at section 25a downwardly toward a lower terminus from each side of which an ear 19 projects. The lower lug portion 26a is also folded or bent to a V-section about a median fold line 28 as shown in FIG- URE 3 whereby the lateral spacing of the cars 19 is contracted so that the ears may be readily placed between the recesses 17 of the beads 16 as shown in FIGURES 3 and 5. Thus, when the V-bent portion 26a is flattened or restored to its initial condition as shown in FIGURE 4 of the drawings, the cars 19 will be projected laterally into the recesses 17 thus to secure the fastening lug 11a in its desired pivotal mounting on the metal chime 9. This may be accomplished by hammering the lower portion 26a of the fastening lug 11a in the vicinity of the fold line 28, flattening said lower portion and thus, in effect, driving the ears 19 laterally into the receiving recesses 17.

It will be apparent from the foregoing that there has been provided novel fastening lug means and a novel combination of a fiber drum having a metal chime on one end thereof in conjunction with the fastening lugs. Furthermore, alternate novel methods by which the fastening lugs of the present invention may be secured to the metal chime of the fiber drum have been presented.
