' Filed Apr. 27,1956, Ser. No. 581,230 4 Claims. or. 214-317 This invention relates toimprovements in receptacles for the efiicient and expeditious loading and dumping of loose materials, either wet or dry, or a mixture of the same. The improved receptacle is adapted for use with available loading, hauling and dumping equipment, including cranes, hoisting vehicles or other equipment for tilting and dumping the receptacle.

The primary object of this invention is the provision of an improved receptacle or bucket adapted to meet the needs of the current and increasing collection of refuse around such establishments as super markets, retail stores, hospitals, housing units, eating places, etc. Generally, this refuse is in the form of garbage, vegetable waste, sweepings, factory wastes, disposable packaging and other loose materials. Such materials accumulate quickly, and it'has been an increasing problem to efficiently and economically handle them; The improved receptacle of the present invention includes an arrangement of parts which enables the quick loading and mass accumulation of materials therein from docks, platforms and other locations. It has discharge closure means such as Will enable the expeditious dumping of the materials therefrom without the necessity of manual intervention and manipulation of the closure means.

A further object of this invention is the provision of an improved receptacle construction, adapted for the'collection and dumping of loose materials, which can be manufactured and sold at comparatively low cost consistent with the strength and durability and interchangeability of parts. Since the materials to be handled in many cases are socially objectionable; the improved receptacle construction includes an improved closure means to prevent escape of objectionable odors, and access of insects and drainage water to the receptacle chamber. Its construction enables the satisfactory handling of materials from a sanitation and good housekeeping standpoint, even over considerable periods of time, in all sorts of weather. The chamber of thereceptacle may be readily disinfected and cleaned. A further object of this invention is the provision of a loading and dumping receptacle adapted to be used with vehicleshaving hoisting equipment for manipulation of the receptacle wherein means is provided for the automatic opening and shutting of discharge closures as an incident of manipulation of the receptacle into and return from dumpingpo'sitions. r i i Receptaclesof the nature of this invention when placed below platforms and particularly at manufacturing establishments where resilient bundles of paper or other materials are packed by tamping such, at the rear end of the chamber, has-atendencyto form "a rather solid 'column at the discharge closure. When the receptacle is tilted into Patented July. 5 195K) ice into dumping position will freely discharge the contents from the receptacle; thus breaking the compacting effect of the tightly packed material to be discharged.

A further object of this invention is the provision of a heavy and ruggedly constructed receptacle for the purposes above described which is provided with a discharge opening and closure means therefrom constructed in such a mannerthat when it is tilted for dumping from a comparatively high vehicle all parts of the closure will be at a reasonably good distance from the ground or sanitary land fill, and therefore unlikely to be damaged by contacting objects on the fill, dump or ground. 7

A further object of this invention is the provision of an improved loading and dumping receptacle having rear discharge closure means so arranged that the chamber of the receptacle provides a sort of sump into which objectionable and odorous draining fluids may collect; the receptacle still being provided with a discharge opening which is of such rear and top area as to facilitate efficient and quick dumping of the contents from the receptacle no matter how tightly such may be packed. i

A further and important object of this invention is the provision of a receptacle construction for the purposes herein described having an articulated combination top and rear end closure construction for a discharge opening which when the receptacle is in dumping position is of greater cross sectional area than the transverse cross secdumping position this solid mass acts as a slug to keep the contents'frorndischarging. It is therefore an importantobject of this inventionto so arrangethe closure tional area of the chamber of the receptacle, whereby to enable instant and free unobstructed dumping of a load.

A further object of this invention is the provision of an improved receptacle construction adapted for use with equipment as herein set forth including a novel collapsible discharge top and end closure construction, the top closure portion of which is provided with charging closures. l

A further object of this invention is the provision of improved, operating means for automatically manipulating closure constructions of dumping receptacles.

Other objects and advantages of this invention will be apparent during the course of the following detailed escription.

Figure 9 is a side view of another modified form of receptacle,-shorwing an improved charging closure con struction. i

In the drawings, wherein for the purpose of illustration are shown preferred and modified forms of the invention, the letter A may generally designate a loading and dumping receptacle having the general characteristics of the loading and dumping receptacles set forth in my copending applications Serial No. 463,646, filed October 21, 1954; Serial No. 536,649, filed September 26, 1955, and Serial No. 579,030, filed April 18, 1956; the same having improved charging and discharging closure means and means for automatically actuating them.

The receptacle A is adaptedto be used in connection with a vehicle or truck body -B having hoisting equipment C thereon. a

The receptacle A is further provided with improved discharge closure construction D having an improved automatic operating structure E therefor.

The receptacle A is the general type set forth in the objects of this invention and may be hoisted and dumped either by means of equipment located upon the vehicle, or by other means. If a vehicle B having hoisting equipment C is used for handling the receptacle A, such may include a chassis 25 having running wheels 26. The hoist means C includes a pair of lift arms 27 pivoted at 28 at the rear of the frame 29 located upon the chassis 25, at each side thereof, and operated by hydraulic means 30. Such type of vehicle for manipulating loading and dumping receptacle is shown in Patents 2,200,020; 2,313,514 and 2,069,697 and need not be further enlarged upon in this application. The vehicle B includes a dump hook 31 pivoted upon the rear of the frame 29, collapsible into a slot 32 or extensible therefrom for assisting in tilting the receptacle into dumping position; this dump hook 31 being operable by control means located in the cab of the vehicle as is well understood by those skilled in the art to which this invention relates.

The boom arms 27 are each supplied with a pair of flexible chains 35 and 36 having key plates 37 at the lower ends thereof for releasable attachment to dumping lugs 38, located in spaced relation upon each-side'of the vehicle.

'Other means may be provided for manipulating the bucket, such as a crane or other free swinging hoist means.

Referring to the construction of the receptacle A, the

same may include a bottom wall 40, side walls 41, a top wall 42 and a rear rigid wall structure 43. The top and bottom walls may be in parallel relation. A front wall structure 45 includes as is shown in Fig. 4 an upper wall portion 45 positioned at right angles to the top and bottom walls, an intermediate wall portion 45* which is slightly angled downwardly to the rear, and a bottom or more acutely rearwardly angled portion 45. The rear wall 43 is diagonally sloped at an acute angle to the vertical, upwardly and to the rear. All of the walls are welded or otherwise securely connected together. It is necessary to provide a rear sloping wall 43, which in this case is rather high, in order that the bottom of the chamber of receptacle A forms a sump for collection of liquids. The wall 43 enables easy tilting of the bucket to a dumping position off the rear apron 46 of the vehicle and facilitates easy sliding discharge of the receptacle contents.

The rigid part of top wall 42 of the receptacle is rather small in area. It is preferably provided with forward charging closures 47 which are hingedly connected at 48 upon'a longitudinal center portion of the top wall. Springs 49 are provided for each closure 47, normally assisting in opening of the s'aid'charging closures. Hasp or latching construction 50 may be provided therefor, which normally cooperates with side charging closures 51 opening at the top wall, which is shown in Figure 3.

hinged at 52 on vertical axes for forward swinging; the said side charging doors having hasp or latch locking or holding means 53. The charging

closure

47 and 51 when opened provide unobstructed top and side closure openings for filling the receptacle A.

In the previously described objects of this invention mention has been made that the materials to be loaded and dumped with respect to conventional receptacles sometimes have a tendency to form a rather solid column at the discharge opening. Thus, when such a receptacle is tilted into dumping position this solid mass acts as a slug to prevent efiicient discharge of the contents. It is therefore a principal object of this invention to provide a discharge closure construction D which operates over a closure opening and extends not only along part of the top of the receptacle but also is located at the rear end thereof. It has a maximum plane cross sectional area designated at y in Figure 4 of the drawings which is greater than the vertical cross sectional area x of the chamber 46. The receptacle A is of uniform width from end to end. It therefore can readily be understood that any mass packing of materials will readily slide over the wall 43 when the receptacle or bucket is in discharging position, as shown in either Figure 2 or 3 of the drawings, and will pass freely through the discharge opening represented by the cross sectional area designated at y in Figure 4.

Referring to the details of the closure construction D and its operating means E, I may provide a top and rear closure construction of rigid formation such as shown in my application Serial No. 579,030, filed April 18, 1956. However, I prefer to provide a collapsible hinge or articulated discharge closure construction consisting of a top closure portion and a rear end complementary closure portion 61.

The top closure construction is preferably hinged at 62 upon the top wall 42. It covers the discharge The free marginal portion of the closure 60 extends beyond the sloping rear edges of the side walls 41 for a cooperative action with the complementary rear closure 61 in a manner to be subsequently described. The discharge closure 60 may be provided with openings therein over which charging closures 64 operate, hinged at 65 along the longitudinal central portion of the closure 60. If desired, springs 66, such as set forth in my above identified application may be provided, normally tending to open the closures 64. Suitable top hasps 68 may be provided for each of the closures 64. Other side hasps 68 may also be provided, the complementary staples 68 therefore being located upon the side walls 41 of the receptacle.

The operating means E is not only an operating means for the rear end closure portion 61 but it directly supports it. The closure 61 is intended to cover the rear end wall discharge opening beyond the margin of the top closure 60. It is provided with rollers 72 along the top margin thereof which slide beneath the surface of the top wall discharge closure 60, in engagement therewith, for opening of the discharge closure portions. These rollers normally rest in notches 74 provided in the side walls 41, as shown in Figure 3, in position below the overhanging margin of the closure 60 in order that when the means E is brought into action they will lift the closure 61 and slide beneath it with the closures in substantial parallelism.

The means E preferably consists of closure supporting and operating levers 80. They are preferably welded to the side margins of the closure 61, and overlie each side wall 41 of the receptacle. These levers or arms extend in planes at right angles to the closure 61. The levers are pivoted short of their lower ends upon the shanks 82 of the rearmost lift lugs 38 or independent pins may be provided therefor. As shown in the drawings the arms or levers 80 may be provided with detachable bearing plates 85, held in place .by bolts 86 in order to pivot them upon the shanks of the lifit lugs or other pins provided therefor.

As has been described in my copending application Serial No. 579,030, filed April 18, 1956, a dump bar crank type construction has been provided to assist in initial opening of the discharge closures and for latch type operation. In the present application it is preferred to provide a dump bar 90 pivoted upon brackets 91 secured to the lower part of the rear wall 43 of the receptacle. This dump bar 90 intermediate its ends is provided with a rearwardly offset crank which includes'a dump rod portion 93 located in position to be engaged by thetrip hook 31 of the vehicle B or a trip hook similar thereto, as indicated at 31, located upon a plat form or dock 94. seee Figure 2 and also shown in the modified forms of Figures 7 and 8.

At the ends of the dump bar 90 along the outer side walls of the receptacle are located operating levers 95. They are rigidly connected to the dump her 90 and extend in closeproximity to the outer sides of walls 41 for appreciable distances upwardly therealong. At their upper ends they are pivotally connected at 97 to operating links 98. In turn the links 98 are pivoted at 99 to the lower ends of the supporting arms, standards or levers which form a rigid part of the closure.61. These connections 99 are disposed at the lower ends of the levers 80 at the opposite side of the pivotaxesof the shanks 82 with respect to the closure 61.

Springs 100 are provided, connected to the intermediate portions of the operating levers 95 and at their opposite ends at '101 to the side Walls 41. The springs 100 are tensioned to normally hold the levers in downward forward position to assist in pulling the closures to a shut position. A guide strap 105 may be provided, in welded position upon each-of the walls 41 to limit fore and aft positionsof the operating levers 95; the end pordons-105 of these brackets 'being shown in Figure 3 and acting as stops to etfect a motion limiting meansg J The normal position of, the operating means E and the closure. construction D is shown in Figures 1 and 4 of the drawings. The closure 60 may be provided with the improved latch construct-ions 110 as set forth in the copending applications above identified. When the receptacle is to be tilted for engagement of the crank por-' tion 93 with the trip hook 3 1 or 31 as the case may be; the hoist mechanism is brought into play in a well known manner for such tilting, to the rear, upon the trip hook 31 as a pivot. Due to the weight of the contents of the receptacle and due to change-in the positions of the discharge closure, as well as due to the weight of the receptacle and its contents acting upon the crank of the dumpibar and through the linkage and the levers 80, the closure portion 61 will slide along the under side of the top discharge closure portion 60, gradually clearing the discharge openings at the top and end of thereceptaclc. The final dumping position of the parts is shown in Figure 3. The crank effect of the operating construction E plus the weight of the contents to be discharged and the shifting in the position of the closures as the receptacle tilted may be solely relied upon for causing the discharge opening and closing of the closure construction D. Also a spring construction such as disclosed I and fully described in the above identified copending applications maybe used This may consist of a powerful spiral spring 120 connected at 121 at its rear end in a suitable closure box 122 provided upon the top wall structure 42. The fore end of the spring 120 may be connected at 122 with a controlling cable 123. The latter may be reeved around a sheave 124 and extended forwardly for connection at 125 with the top wall closure portion 60 intermediate the fore and aft ends thereof. I may provide a guard 126 for the pulley construction 124, and a suitable stop 127 may be provided to limit the action of'the spring in its opening movement of the closure 60. As shown in Figure 4 of the drawings, the line of the cable 123 may lie beneath the axis of the hinge 62, or as set forth in some of my copending appli' 62 as shown in Figure .4 the action of the spring is.

normally to maintain the closure 60 in a shut position.

In Figure 2 the receptacle A is shown as supported by means of a crane or other type of hoist chain 130 connected to the foremost of the lift pins 38. In this position the receptacle is shown dumping materials from a dock or platform and the relation of the discharge doors is clearly designated.

A different type of receptacle closure construction D may be provided as shown in Figures 7, 8 and 9, wherein the rear closure portion 60 is hinged at 62 It terminates short of the top discharge opening of the receptacle A. In this form of invention the rearmost discharge closure construction 61 may consist of a top wall closure portion and an end wall closure portion 136. They are rigidly connected together. The fore end of the top wall discharge closure portion 60* is upturned at 137 and beneath it lies a roller construction 138 attached at the fore end of the closure portion 135 of the rear closure 61". Another roller construction 139 is provided at the juncture of the

closure portions

135 and 136.

As the lever mechanism E is brought into play for moving the lever arms 80 which are rigidly welded or otherwise aflixed to the

door closure portions

135 and 136, as shown in Figures 7, 8 and 9, the rear roller 1 38 first rides beneath the top wall discharge closure 6% and as the closure constructions are further opened, during receptacle tilting, the rollers 138 take the position shown in Figures 7 and 8.

In all forms of the invention a spring 140 may be used ly tend to open the closure 60. As shown in Figure 8 all springs may be eliminated.

As shown in Figure 9 an 'endwise hinged charging door may be provided for the closure portion 60 shown at and hinged at 151. This charging door 150 swings upwardly and to the front and I may or may not use the spring arrangement normally tending to open the charging door 150 as it is shown in Figure 9 and indicated by the cable 123* therein shown. The spring arrangement is useful to help the operator open, the charging door 150 and hold it open until the door is manually closed prior to dumping of the container.

A hairpin type of spring 100 may be used as is shown in Figure 2 coiled around the shank of lift lug 38, one end of which is connected to the lever 80 and the other end welded to the receptacle. It actswith tension normally with tendency to open the discharge doors.

It will be apparent from the foregoing that an improved discharge closure construction for tilting types of loading, hauling and dumping receptacles has been provided in which a very wide and long discharge opening may be provided and in which the discharge closure arrangement is such as to give appreciably greater ground clearances than with present receptacles of this type. It will be noted that the pivot points of the leverage arms 80 and 81 are preferably above the half way height of the receptacle side walls.

' This permits the main weight of the receptacle and its .dump, bar crank diminishes but doe not entirely disappear until the receptacle is resting in its horizontal position. As a result the discharge doors normally remain opened until horizontal position is approximately reached. At that timethe weight of the closures, with diminishing forces acting thereon to hold them open, will cause them to move automatically to closed positions. 7 7

Various changes in the shape, size and arrangement of parts may be made to the forms of invention herein shown and described, without departing from the spirit of the invention or scope of the claims.
