SUMP-TYPE CONTAINERS FOR TRANSPORTlNG AND DUMPING EQUIPMENT Harry W. Jones, Knoxville, Tenn., assignor toDempster Brothers, Inc., Knoxville, Tenn., a corporation of Tennessee Application December29,:19 52, serial No. 328,310
4 ;,15 Claims. Cl. 298-30) invention relates to improvements in sump-type containers, and more particularly to the type of containers .used for trash, garbage, and other refuse.
\ if It has been customary to handle refuse containers with transporting and dumping equipment of the types set forth in the patents of George R. Dempster, No. 2,281,183, April 28, 1942, and No. 2,369,722, February 20, 1945,
Such containers customarily are filled while sitting on the ground or on the floor, street, etc., and thereafter may be picked up by the transporting and dumping equipment on a motor vehicle, on which the container may be transported to the point of dumping, thecontents discharged, and returned or hauled to the point of reuse. Frequently, a
considerable quantity of liquid may be received in the tainer is raised and tilted forward on the transporting equipment in itscarrying position, the liquid is retained in the container without danger of leaking out.- 7
A further object of the invention is to provide in a drop. bottomfcontainer the provision of a sump at or adjacent. the'point of connection of the ,drop bottom door Patented Dec. 4, 1956 the container in open position; and
Fig. Sis a similar view with the door in closed position. The invention is shown as applied to transporting and dumping equipment of the character generally represented in the Dempster Patent No. 2,369,722, February 20, 1945, merely as an example of the type of equipment in connection with which it may be used.
This transporting and dumping equipment includes a motor vehicle chassis generally designated by the numeral 1, upon which is mounted a hoisting unit, comprising a sub-frame 2 having a container rest generally indicated at 3 mounted thereon and inclined forwardly of the motor vehicle. Boom arms are shown at 4, pivotally mounted at 5 at their forward ends, to the sub-frame 2 and adapted to'be raised and lowered by hydraulic V hoists 6.
A skid frame is shown at 7 mounted on the sub-frame 2 for bodily movement lengthwise relative thereto be- Suitable means is provided for moving the skid frame 7 tween the position shown in Fig. l and a forward position in which the container may be lowered onto the rest 3.
forward and rearward of the chassis, as described more with therbody of the container which will receive and enclose the liquid contents thereof and prevent leakage through the crack between the door and container when the container is tilted in carrying position. 7
Still another object of the invention is to provide for the sealing of the crack between a drop bottom door and 'the body. of a container on which it is used againstthe leakage of the contents therefrom when the container is tilted 'incarrying position.
. These objects maybe accomplished according to one i embodiment of the invention by constructinga drop bottom 'containerwith a sump therein which normally contains liquid. This sump includes a receptacleprovided on the drop bottom door adjacent'the point of the body Of the container which willtrapthe liquid. in ithe containeragainst leakage when the container is tilted in its carrying position on the vehicle. This provides a,
'lakproof sump with a receptacle of substantial, quantity .that will allow the container to tip forward to a considerable degreewithout leakage through the crack between the doj or and the body of the container. Provision may be 'rnadeffor sealing the crack and shedding the contents of the container when the door is opened, as by pivotal connection between the edge of the .doorfand t the ,provision of a sealing gasket or flap which overlies are crack therebetween and thus insures proper shedding fully in the Dempster patents referred to above. The free ends of the boom arms'..4 support the container by flexible devices such as chains 8, attached to the boom arms at 9 to raise and lower the container to and from generally asdescribed above, is set forth and disclosed more fully in the Dempster patents referred to, particularly No. 2,369,722. r
The container illustrated asf an embodiment of this invention, for use with thetransporting and dumping equipment is shown in Figs. -1 and 2, and more fully in Figs. 3 to 5 'This container is constructed preferably of sheet metal of relatively heavy gauge, according to the size and capacity of the container and the material to. be contained therein,,but is substantially of rigid unitary structure. End walls are shown at 10; front and back walls at 11 and 12; and a bottom at 13, all being formed ofsuitable steel plates or the like, rigidly con-. nected, together as by welding, or other fastening means.
The bottom '13 is provided withupturned end portions 14 formed rigidlyftherewith in positions to fit into cutout notches 15 provided in the end walls, 10 of the container, and may be made as usual by notching out the end plates,- using the cutout portions to form the end sections 14, of the bottom 13. T a
The bottom 13 is also provided with upwardlyinclined forward and rearward'edgeportions 16 and", respectively, which cooperatewith the end sections 14 to provide a sump in' the drop bottom 13 for containing liquid therein.
i The drop bottom 13 is hinged to the forward wall 11 the contents of the container.
The hing'ed corine'ction'between the drop bottom 13 tween at the hinge edge of-Tthe drop bottom door 13. I have provided a deflector plate 19 overlapping this crack inbrdftdshd the contents of the contatnefover the front wall ltand may be held inplac'e, as shown,'by a 4 14 to strengthen the latter at the points where the lift- "in'g'force is applied. This adds materialrigidityto the brace 20 interposed'between' the raw-er edgeiportion ofv "the p'la'te 19* and the "plate of "the front wall 1"1.
, This shedding action 'may be increasedby' 'the pro- 'isealing means'is provided by a resilient ornubber flap 21 "wliich'is attached at-oneedgeto the lower edge of the plate 19 in positionito be engaged by the adjacent portion of'the drop bottom door'13'when the latter is closed. The resilient sealing means may be connected also with the door, 'if' desired, and be in the form of a bellows or other 'yie ldable connection therebetween that will effectively seal" the crack.
The hinged edge portion of the drop bottom door 13 "is'provided also with a receptacle 22 therein adjacent 'the'hinge 18. This receptacle 22 is formed'by. an'upwardly inclined wall portion 23 in cooperation with the "inclined'edge portion'16 of the'door 13, which portion 23 extends throughout the length of the container and has a forwardly turned top portion 24. These receptacle portions 23 and'24 may be provided by plates extending between the upturned portions 14 'on the drop bottom door and Welded or otheryvise secured thereto'in "sealing relation therewith so as'to form a closed receptacle in the hinge edge of-the drop bottom door. Braces may be provide'datintervals along'the' length of the receptacle 22'as 'indicated' at 25. The top wall portion 24 is in position to engage or "be connected with the sealingrnember 21when the door isin its closed position as shown'in Fig. 5, whereby to seal thecrack therebetween, as well door is'open, as il1ustrated in Figs. 2 and 4. p v 'Lifting pins areprovidedat26 on the end sections 14 of the do'or13for detachably engaging the free'endsof as to insure of proper shedding of the contents when the drop bottom door at thesepoints.
The container may be open at its top or provided with any suitable closure or doors therefor as desired, according to the material to be handled therein and the desirability for enclosing such material.
The container is adapted to be loaded, transported and dumped substantially as set forth more fully'in'the Dempster patents referred to above, particularly No. 2,369,722. When the container is sitting in its .level position on the ground-during filling, as illustrated in Fig. 3, the sump provided in the door 13 will contain a 'considerable quantity 'of liquid therein, having a liquidlevel whichis at the height of theupper edges of the inclined portions 16 and 17, as indicated atAin Fig. 3. For one size of container, this liquid level will hold 110 gallons of liquid.
Whenthe same container is lifted from its level position, shown, in Fig. 3, to a 'positi on in which it'rests against, the'skid frame 7,' as shown in'Fig. 1, it will be noted'that the body of the container tilts forward of the tion.
the chains 3 to lift the container fromritsfilling position "on the ground or other surface onto thes'kidframe 7 V and tohold the 'container in'durnping position, as well as for handling the container gerierally/ The chains'S extend from'the lifting pins 26 over boom restsi27 secured to the end walls'10 of the container at points above the lifting pins '26 and'adjacent the front wall 11 'soasto insure of proper support of the container by the chains. 7
As set forth more in detail in"theabove-'mentioned Dernpster patents,;"theskid'frame 7 is'jprovided'with one ormore dumping hooks thereon for engaging 'theibo'dy of the co11tainer'for"dumping. .The front wall "11 is shown as providedwith'a'n' indentation therein, generally indicated at 28, within'whichis' located across bail'f29 adapted to be 'engagedby the'hook. (not sHe-wnyon the a *skid' frame 7 to hold the body of the container elevated,
as illustrated inFig. 2, for dumpingofthejeonterits upon 'fl ring of'the drop bottoml3."
The wal ls' of 'the'c'ontainer are"secu r'ely reinforced as forcing bars are shown also at 30 on the drop bottorn bottom, designated :31, has "upturned fiefii'ds32 "intermediate the width offfthe"door' inimediatelfbnea'th the --lift ing"pins 2'6aiid welded securelydo the end"se'ctions usual by ribsor reinforcing membersj'there'on' and'l extending circumferentially around the"coritainer'. 'lRinvehicle through atleast 15 /2 degrees in its carrying posi- Inasmuch, as a crack is formed at the point of the hinged connection between the drop bottom door 13 and thebody of the container along the front wall 11, the liquid contents would spill out of the container almost entirely in tilting the container to the position shown in Fig.1, with only a very small quantity of the liquid remaining therein, as-diagrammaticallyillustrated by the dotted line B in Fig. 3. However, by the provision of the receptacle 22 along the hinge edge of the drop bottom door 13, this liquid carrying capacity in the tilted position of the container is raised to the liquid level generally indicated by the dotted line C in Fig. 3. In the example given above as a representative size of container, the liquid level at the point C is gallons capacity, which therefore exceeds the liquid capacity when resting flat on the ground and thereby 'will retain in the container all of the liquid contents that would be retained when the container is flat in' its fillingposition without spillage of any of the liquid contents in tilting of the container to its carrying position. Thus the receptacle "provided on the drop bottom door is more than sufiicient incapacity to contain intact all of the liquid that has been retained in the sump portion of the container during filling; *Thus, an effective leakproof sump bottom' container is provided that will retain the liquid contents, event when the container is tilted to its carrying position. The construction provided herein would leave a crack and possibly a ledge at the upper'edge of the door in open'position, as shown in Figs. 2 and '4. I'have provided'shedding and sealing meansalong thisjportion of the hinge edge of the drop bottom door by'a deflector plate -19-and sealing means 21 that overlie the crack of the receptacle 22 to insure of proper shedding of the contents of the container over the open door as the latter hangs down in its open position, substantially as shown in Fig. 2. The rubber, flexibleor resilient flap 21 need'not' necessarily'be connected with the'receptacle walls 23 and 24, although'it may be connected therewith if desiredpand thus fold .up "or' telescope 'in'the manner 'of-agbellows during the closing action ofthe' drop bottom'door. p f In this "way I have .provided an fetfectiveleakproof ;surnp that will're'tain'all of the liquidjcontents .of the container evienj during transporting of "thellatter inan in- 'clined orwt'ilted position which is highlydesirable with containersof"thisjtype. v
'While the'invention has been illustrated and described in one -embodirnent,"it is, recognized thatvariations and changes may. be "madeithereiri without departing from the invention set' forthfin' the claims. 7
