Definitions

• This invention is related to the field of storage drums.
• the present invention is embodied in a storage drum having multiple storage compartments which allow at least two dissimilar materials (e.g. liquids, particulate solid materials, slurries or the like) to be stored separately of one another in respective ones of the compartments but be readily available for collective use (e.g., as a mixture of such materials) .
• dissimilar materials e.g. liquids, particulate solid materials, slurries or the like
• pourable dissim ⁇ ilar materials e.g., liquids, particulate solids and the like
• dissimilar materials e.g., liquids, particulate solids and the like
• agricultural chemicals are desirably applied to crops as an ad- mixture so as to improve application efficiency and/or chemical efficancy.
• each drum segment will be formed by a pair of semicircular end panels which are joined to, and spaced-apart by, a side wall having a hemi-cylindrical wall section and a substan ⁇ tially rectangular planar wall section.
• the planar wall section of one drum segment (the female drum segment) will, moreover, de- fine a longitudinally oriented re-entrant groove which unites with a longitudinally oriented tongue protruding from the planar wall section of the other drum segment (the male drum segment) . Therefore, when the tongue and groove are united with one another, an overall cylindrical drum structure will result.
• each drum segment establish a diametrical parting plane when the tongue and groove are united with one another.
• the hemicylindrical wall segments are provided with longitudinally spaced-apart and outwardly pro- truding pairs of roll stops close to this parting plane.
• the up ⁇ per semicircular end panels are each provided with a bunghole formed in relationship to the roll stops such that, when the drum structure is turned on its side and prevented from rolling by one set of roll stops, the bungholes will be substantially vertically oriented with respect to one another.
• the con- tents within the hemi-cylindrical drum segments can selectively be dispensed by positioning that segment's bunghole in the lower vertical position relative to the other bunghole.

• FIGURE 7 is a perspective view similar to FIGURE I, but partly in section;
• FIGURE 8 is a perspective view illustrating the manner in which 5 the drum contents may be dispensed.
• FIGURES 1-7 depict a particularly preferred em ⁇ bodiment of the multi-compartment drum 1 according to the present invention.
• the drum I essentially includes sepa-
• Each of the drum segments 12, 14 is comprised of a pair of semicircular upper and lower end panels 12a, 12b and l 4 a, 14b, joined to and separated by a side wall comprised of a hemicylindrical exterior wall section 12c and
• the lower end panels 12b, 14b are preferably provided with arcu ⁇ ate recesses 12b' , 14b' (or ribs, if desired) for structural 20 strength (see FIGURE 3) .
• the side wall sections 12c, 14c are preferably provided with recessed handles 12c' , 14c', respectively, to facilitate handling of the drum 10.
• the male drum 25 segment 12 includes a tongue 12e outwardly protruding from the inner wall section 12d, while the female drum section 14 includes a re-entrant groove 14e defined by the inner wall section 14d.
• the tongue 12e and groove 14e are conformably shaped so that when united, a relatively tight interference fit is achieved.
• the tongue 12e includes an arcuate head portion 12e' and a neck portion 12e" of narrower dimension. The head portion 12e' will thus fit conformably into the arcuate receiving channel I 4e of the groove 14e, while the entranceway 14e" of the groove is dimensioned so as to closely fit the neck 35 portion 12e".
• This interlocking arrangement of the tongue 12e/ groove 14e prevents the drum segments 12/14, respectively, from readily separating from one another.
• the longitudinal dimensions of 40 the tongue 12e and groove 14e are each less than the overall lon ⁇ gitudinal dimension of drum 10. This feature of the present in ⁇ vention will thus ensure that the two segments 12 and 14 are only united to one another in the intended orientation — i.e., mating of the drum segments in a reverse orientation to that shown in 45 the drawing FIGURES is prevented.
• the lower ends of the tongue 12e and groove 14e are shown in the drawing FIGURES as extending to the end (bottom) wall panels 12b and 14b, respectively, they each could terminate in a manner similar to their upper ends (i.e., each spaced from the bottom wall panels 12b, 14b, respectively) .
• the side walls 12c, 14c of the drum segments be provided with circum ⁇ ferential band-receiving channels 12f, 14f (see FIGURE 6) which receive a suitable restraining band 16 (see FIGURE 1) therein.
• the restraining bands 16 thereby serve to prevent relative longi ⁇ tudinal slippage between the drum segments 12 and 1 4 and may be used regardless of the particular configuration of the tongue 12e and groove 14e so as to improve the structural integrity of the drum 10 when the drum segments 12, 14 are united to one another.
• each of the roll stops I2g is circumferentially opposite to a respective one of roll stops 14g while each of the roll stops 12h is circumferen- tially opposite to a respective one of the roll stops 14h.
• each of the roll stops 12g, 12h and 14g, 14h will de ⁇ fine a convexly arcuate (e.g., hemispherical) surface.
• the upper end panels 12a and 1 4a are each provided with respec ⁇ tive bungholes 12i, 14i (see FIGURE 8) and caps 12j, 14j, respec- tively.
• the bungholes 12i, 14i thus.provide access to the inte ⁇ rior compartments 12k, 14k (see FIGURE 7) of the segments 12, 14, respectively, so that the compartments 12k, 14k may be filled with a respective volume of dissimilar pourable material, and to allow a respective dissimilar pourable material contained therein to be dispensed when desired.
• the asymmetrical orientation of the circumferentially paired roll stops 12g/14g and 12h/14h and the placement of the bungholes 12i and 1 4i near the paired roll stops 12g/14g and 12h/14h, respectively, allows the bungholes 12i and 14i to be vertically oriented with one another when the drum 10 is turned on its side and rests upon the paired roll stops 12g/14g or 12h/14h.
• the vertical orienta ⁇ tion of the bungholes 12i and 14i may be reversed by simply rol- ling the drum 10 along its circumferential side surface (arrow A_ in FIGURE 8) until it translates a distance (arrow A 2 in FIGURE 8) which is substantially equivalent one- half the circumferential dimension of drum 10, and rests upon the other set of paired roll stops 12h/14h.
• the respective contents within the compartments 12k and 1 4k may be dispensed separately from the drum 10 through bungholes 12i and 14i, respectively.
