18 Claims. (Cl. 294-69) This invention relates to a container and more particularly relates to a large metal container for shipping and handling drilling mud, Portland cement, and similar'dryv pulverulent materials. i

In oil eld operations it is necessary to ship and handle large volumes of drilling mud quickly, economically, and without contamination of the mud with water or other materials. The containers used for this purpose must be sturdy, as light as possible, and susceptible of easy handlng and storage. emptied in a short period of time and there should be no tendency for the mud to stick within the container upon emptying.

According to this invention there is provided a light weight, rugged mud container which may be easily and quickly filled and emptied and sealed in a water tight condition. The container is so constructed that it may be readily and quickly stacked upon other similar containers by conventional container handling equipment without the necessity for accurately aligning `the/upper and lower containers. Quick opening upper and lower access openings are provided and each is'so constructed as to substantially eliminate water seepage into the container. A lsingle lever actuated lock is provided for the emptying door and Vprovision 4is made for latching the lock in a locking position. The bottom door is of an extremely rugged construction and contains bracing members which cooperate with the door lock. A drip lip is provided around the'lower door to prevent water or other uid seeping up into the'contaiuer.

It is accordingly a primary object of the present invention to provide an improved container for shipping and handling dry pulverulent materials in general and drilling mud in particular.

lt is another object of the invention to provide au improved metal container having quick opening upper and lower access openings with provisionsvfor substantially eliminating water seepage into the container.

It isanother Vobject of the invention to provide improved'metal containers which may be easily stacked with-v out the necessity of containers. p

-It is another object of the invention to provide an improved metal container for dry pulverulent materials which is so constructed as to prevent caking and packing of the pulverulent material and to promote rapid emptying.

lt is another object of the invention to provide an improved metal container for handling dry pulverulent ruaterials havinga self-latching lock on the bottom access opening.

lt is Vanother object of thev invention to provide an improved metal container for handling dry pulverulent materials having a quick opening lower access openinghaving a light weight sturdy closure door.

Figure 8 is a vertical section ofthe lower closure taken on line 8-8 of Figure 7; and

Figure9 isa vertical elevation showing details of the latch construction on the lower closure.

Referring to Figures l, 2 and 3 there is seen a container which consists of a rectangular'upper portion 6 and a wedge shaped lower portion 8. The upper portion 6 is comprised of side walls 10 and 12 which are joined to end walls 14 and 16. The end walls 14 and 16 extend straight down to form parallel walls of the lower portion 8, while the side walls 10 and 12 are bent inwardly approximately 30 degrees to form sloping walls 18 and 20 defining the wedge shaped lower portion 8.

The upperends of the side and end walls are provided with inwardly directed auges 24, 26, 28 and 30 which are diagonally cut at the edges and welded together along seams 32, 34, 36 and 38. A square lid deck 40 having curvate depending flanges 42 is lwelded to -the wall anges 2430 to seal the container top. A pair of lifting lugs 44 and 46 pass through apertures in the flanges 28 and 30 and are welded to the inside ofv end walls 14 and 16, to the wall anges 28 and 30 to the flanges 42 of the lid deck 40.

Referring to Figure 4, the lid deck is provided with a centrally located aperture deined by a vertically upstanding flange member 52 which may either be formed as an integralk part of the lid deck or as a separate member welded to the lid deck as shown at 54. The opening formed by the upstanding flange 52 is closed by means of a lid 56 having a depending angeSS and a square end 60 and semi-circular end 62. A heavy pipe 64 is welded Iat 66 and 68 within the square end of the lid 56, as is best seen in Figure 5, and matching` apertures are provided in the depending flange 58 adjacent the ends of the pipe 64. A pair of L-shaped brackets 70 and 72 are mounted on the lid deck 40 adjacent these apertures and the lid is hinged to the deck by means of a bar 74 which passes through the brackets 70 and 72 and the pipe 64. A pair of cotter pins 76 and 78 secure the bar 74 in position. A gasket 80 is mounted within the lid 56 and sealed against the upstanding ange 52.

v The lid 56 is locked by means of a latch 82 shown in detail in Figure 6. A bifurcated bracket 84 is Welded to the lid deck 40 adjacent the semi-circular end of the lid 56 and a bar 86 is pivotally carried by the bifurcated bracket 84. The bar 86 has an upstanding arm 88 secured thereto between the arms of the bifurcated bracket 84 and this arm passes through a slot 90 in a slotted bar 92 which is welded to the lid 56.

stops for the hook to prevent its slipping oifftheedge of the bar 166 when the loaded container isdropped on one ccnjner.v Since the containeris relatively flexible and, is

ysubjectedito very severe handlingthis featurehas been found desirable to prevent inadvertent unlocking-with a resultinggspillage of thecontainer. contents.v

p Referring to `Figlres l and 2 itiwill be seenthat the 1 `container body is provided with angle .iron support mem-il bers 184,186 and 188. at the. fourcorners thereof andi.

these l are weldedto the body just above -the slopingpor-A vertical walls 102 and 104 of Ythelower portion vof the container body. The lowermost edges 196.. and 198 of A the braces 192 and 194 are below the lowermostA portion of the. bottom door 124 so that;ifthe container is setiL upon Va support whichjisnarrowerthan the spacing be-V tween the horizontal angle `irons 190 and. :191.the .door

is prot ected from damage. The edges 196 andf198 form convenient engaging surfaces fortheforksoffa conven "tional rfork lift to permit easy handling ofthe container'.V

without dama ge tol its lower door.

The transverse vspacing between the horizontalangles 19,0 an'd 191 isY such that oneptcontainer may be. stackedabove the other withpthe .roundedanges 42;.of thelid t jdeck 40 guiding the legs into position. In order;to.stack r the containers a fork lift'truck is driven against thecontainer body'with thel tines of the forkenga-ging the lower edges 196 and 198 of plates 192 and 194.; The container is then lifted to a suicient heights and is deposited uponV *the top of asimilar `container with the rounded edges 42 of the lid `deck 40 lguiding the horizontal bars 190 .and

191 into position. l A seat for the stacking legsis .thus provided at'moderate cost without objectionable projecf. tions `and does not interfere withthe tines of the forklift truck during stacking. It is a simple matter for a single operator to position one container upon another. since it is not necessary to exactly locate the upper containerinv vertical Aalignment with the lower. Due to the Weight of a loaded container, Vusually around'several tons, it is not feasible to stack the containers whenthey are loaded, y.

and since empty containers are returned on the same type barges that deliver the filled containers, there is no necessity to stack the containers in transit. It is, however, important to be able to stack the empty containers to conserve yard space. Since the containers only have to stacked in an empty condition it has been found unnecessary to prevent slippage except from side to side and the same lid deck which accomplishes this function also guides the uppercontainer into position as a means of speeding and stacking operation.

The particular shape of the lower portion of the container body, viz. the two vertical side walls and two sloping sides inclined at an angle of no more than approximately 60 with respect to one another, forms an important feature of the invention. It has been found that where the bottom of a container is conical or pyramidal in shape a wedging action occurs which causes arching of the material so that it is very ditlcult to empty the container contents. The action is often so pronounced that the material directly above the discharge opening falls out making a hole through the material from bottom to top but leaving compacted material all around forming vertical walls. The problem is elfectively solved through the use of the two straight sides in conjunction with the sloping sides. With this construction as the bottom door opens the portion of the material above the opening falls out and there are thereafter two separated and unsupported portions of the material above the sloping sides which continue to fall free. It has been found that in order to obtain this action the angle between the sloping walls 18- and 20 should not exceed approximately 60.

-lIvt will be -apparent from the foregoing that containers constructed vaccording to this invention are sturdy, rela- -tively light in weight and capable of quick filling and emptying by means of quick opening closures. The containers are capable of ready stacking and may be handled by a single operator with a conventional fork lift truck. The container is shaped -to prevent sticking and packing of its contents and is provided with an emptying door which is mounted to prevent seepage into the containers.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
