UnitedStates Patent Tenn.; said Herpich assignor to. Dempster Brothers, luc., Knoxville, Tenu., a corporation-of Tennessee Application September 24, 195.7, Serial No. 685,8*56

11 Claims. (Cl. 214-302) This invention relates to improvements in containers of the character normally used with front end loaders such, for example, as set forth in our prior application Serial No. 657,782, filed May 8, 1957,v of which this application is a continuation-in-part.

Containers of the type referred to usually are placed in accessible positions as, for example, near stores or places of business, to be filled with trash and refuse, and frequently garbage and other disposable materials. Such containers are adapted to be picked up by a hoisting unit mounted on a motor vehicle, either for dumping of the contents into the body of the vehicle, or for transportation from place to place during additional filling, or for dumping at a remote point. It is desirable that the containers be separable from the motor vehicleand hoisting unit, but provision should be made not only for detachable engagement with the containers without requiring an attendant, but also for the secure retaining ofthe containers in place on the vehicle during transportation and during dumping. 1

One object of this invention is to provide for the ready and secure connection of a detachable container with a front end loader which will be effective not only to hold the container in place on the loader, but also to provide for attachment to and disconnection from the loader of a separable container. i'

Another object of the invention is to provide a container with means for engagement by a loader to permit the ready and separable connection of the container with the loader without requiring an attendant to make positive connection therewith and disconnection therefrom.

side thereof be partially open to enable the refuse to be placed or dumped into the container, and a bafe is used on the open side which may be turned into overlapping relation with the refuse, not only to retain it in place during transportation and during dumping, but also to prevent the wind from blowing the refuse out of the coutainer and for directing it into a hopper of the body during dumping. l

According to another embodiment of the invention, the container may be provided with supporting wheels to enable the same to be rolled through narrow passageways or along surfaces where the container may be moved, and to move the same into proper engaging connection vwith the lifting frames of a front end loader when the latter is standing ready to receive the container.

These embodiments of the invention are illustrated 1n the accompanying drawings, in which:

Still another lobject of the invention is to provide a container which has substantial capacity, whichmay be filled as it is carried on the loader above a street or road surface, and yet will retain the refuse material'therein during transportation andv during dumping of the'contents.

A still further object of the invention isito improve the construction of a container for a front end loader to permit the container to be moved through narrow passageways by a rolling motion withv adequate and secure control, and which will enable the container to be moved into engaging relation withfaloader manually, without with. Y

movement of the loader for'pick-up connection there- These objects may be accomplished according to certain embodiments of the invention by constructing acontainer with an upright enclosure -or body portion, which preferably is elongated and has liftingchannels on opposite ends-thereof forming pockets for detachable engagement by aY front end loader to pick up the container for transportationor for dumping. yIt is preferable lto use elongated channels in forming such pockets, because 'f these are capable of receiving the arms'preferablyused The channels may betur'nedeither inwardly or outwardly according to the characterand manner of use of the container. l f

The invention is adapted for use more particularly with afront end loader such, for example, as set forth in our prior application, Serial No. 657,782,`filed May 8, 1957.

Suchra loader is usually mounted on a motor-vehicle, a portion o f which is indicated by the numeral 1 in Fig. 11,--and such vehicle may be provided with a compaction body as shown at 2 in Fig. 16, all as described in more detail in our aforesaid application.

* The front end loader set forth in said patent application includes -a pair of lifting arms 3 mounted on opposite sides of the motor vehicle and operated by power means as described therein, for raising and lowering the arms, or for transporting a container, or dumping the contents thereof into the compaction body 2. through a hopper or opening generally indicated at 4 in the top of the compaction body. V The'forward free ends of the arms 3 are provided with a torque tube 5 connecting said free Yends together, and which torque tube carries a pair of lifting 'forks 46, as illustrated inFigs. 1l to 14. VThese lifting forks Vare adapted for ydetachable engagement with the container, for transporting or handling Ythe same. r

One form of container adapted for the purpose as an embodiment of this invention is illustrated in Figs. l to 6. This form of container includes an upright enclosure for receiving refuse, or the like. The enclosure is Vformed with front and back walls 7 and 8, respectively, anda Ice Patented May 17, r1796()y 3 closed bottom 9, extending therebetween. AThecontainer is elongated and has opposite ends forming closed walls. The length of the container should correspond substantially with the width ofthe vehicle and ,to beV received between the forks 6 on the front end loader. These parts may be `formed of steel plates adequately secured together in rigid relation as, for example, by welding. Risers k11 may be used on the bottom 9, if desired, for holding the container spaced above the iloor, street or other surface, or these risers may be omitted if not required.

Where the container is of substantial height for large capacity, access openings and doors may be provided therein, as found desirable, and according to the practice in the manufacture of such containers. In the embodiment shown in Figs. l and 2, the container is provided with an access opening, generally indicated at 12, in the front thereof, above the front wall 7, and extending continuously between the end walls 10 and downwardly from the top of the container to the upper edge of the front wall 7. This enlarged opening 12 permits the refuse to be dumped into the container as, for example, from garbage and trash cans, and other smaller containers as usually provided in individual households.

Extending along the upper edge ofthe wall 7, below the opening 12, is a support bar 13 which also serves to reinforce the upper edge of the wall 7. This bar 13 may be in the form of an angle bar as shown, and preferably extends throughout the length of the front wall 7. The front wall 7 is also reinforced by plates 14, secured to the oulter face thereof at the ends, as shown in Figs. 1, 2 and 5.

The front wall 7 is provided with sleeves 15 secured upon the upper edge thereof, as by welding, and to the reinforcing bar 13 and plates 14. These sleeves 15 Vare set just inside the end walls 10, and have their inner ends open. They form journal bearings and may Abe provided with lubricant fittings 16.

A hinge member is indicated at 17 in the form of a rod or pipe, rthat extends transversely of the opening 12 along the upper edge of the front wall 7, in bridging relation between the sleeves 15. The opposite ends of the hinge member 17 are jonrnaled in these sleeves 15 for freedom of turning movement with respect thereto. The hinge member 17 may be supported intermediate its length, if desired, as by arcuate bearing members 18, welded or otherwise secured, upon the bar 13, at one or more points, as shown in Figs. 1 and 6.

A baffle plate is indicated at 19, welded or otherwise secured along its upper edge to the hinge member 17, -and extending downwardly therefrom. This bafle platte 119 should be provided with slots therein, to receive the bearing members 18 so as to permit of freedom of turning movement of the baie with v.respect to the body of the container. The lower edge of the batlie19 is shown ,as provided with an offset flange 21 for reinforcement, and normally yto hold the baiile plate spaced outward, somewhat away from the front wall 7.

The container is adapted to be picked up by the hoistking unit on the Vehicle, by engagement of the lifting forks 6 with the container after the latter is filled, either for transportation or for dumping. The container preferably is of `a length substantially to be accommodated between the forks 6, as indicated in Figs. 11 to 14, and suitable means should be provided on the container for detachable engagement by the lifting forks.. Preferably, such means comprises pockets or passages secured to the end walls 10.

In the form shown in Figs. 1 and 2, these lifting pockets areformed of channelsV generally indicated at 22. The lifting channels or passages 22 are open at their opposite ends to receive the lifting forks 6 through the channels from end-to-end thereof, as will be apparent from Fig. y14. The open side ofthe channel 22 is turned toward the adjacent end wall 10, and is welded or otherwise securely fixed thereto. Suitable bracing plates may be provided,

if desired, as indicated `at 23, and .shown as abutting l l Y againstthe upper and lower sides of each channel at the ends thereof. l

The container may be filled with refuse, seated on the ground, street, or other surface, separate and apart from the loading device, as indicated in Figs. 1 and 2, or while `supported on the loader. The .container can be filled through the opening 12 in the front thereof, either by throwing the refuse into the `container or by dumping it in from cans or other smaller receptacles, with the bale 19 in the open position, as shown in Figs. 1 and 2.

Whenit is desired to dump the contents from the container, the loader is moved up to the closed rear wall 8 of the container, and the lifting forks 6 projected through the lifting channels 22. The lifting forks are so formed and spaced from each other/as to fit into the lifting channels, as well as to project through the latter from end to end for supporting the container on the forks and for holding it securely in place thereon. Thereafter, upon operation of the lifting arms 3 and the forks 6, the container is moved to an elevated position over the body of the vehicle as, for example, to dump the contents through the hopper opening 4 into the compaction body 2, as indicated in Fig. 16. It will be noted that the baie 19 swings loosely downward from its hinged connection with the body of the container and thereby prevents the wind from blowing the refuse out ofthe container as the latter is being turnedV upside down during the dumping operation. The baille also serves to guide the ow of the refuse into the hopper or body of the container, as will be apparent from Fig. 16.

Where the container is being iilled with loose, bulky materiahas for instance waste paper, and in any event, when the refuse may contain material that will blow out of the container, the baflie 19` can be turned back upon the refuse to hold it in place, as indicated diagrammatically in Fig. 15. This will be especially advantageous when waste paper and other light waste material is being loaded into the container, and will be securely packed and retained by the balile when the container is sitting in its filling position, as well as during dumping.

A modified form of thek container is illustrated in Figs. 7 to 10, wherein the container is shown as an enclosed receptacle, or body portion, generally indicated at 25, having surrounding walls and abottom adapted to receive and contain refuse. l

In thisforrn, the pockets or passages for receiving lthe lifting forks 6 are formed of outturned channels 26, secured to the opposite ends of the container and open at the outer sides so as `to receive the forks therethrough, as will be described hereinafter. Intermediate the length of the lifting channels 26 and extending transversely thereofinanupright direction are shields 27, to hold the forks 6 spacedfawayfrom the ends of the body portion 25.

In order to facilitate movement of the container and to roll it along the surface on which it is supported, sets of `casters are connected with the bottom thereof, as indicated at 28 and 29, respectively. It is preferred that the casters 28 be swivelled and that the casters 29 be fixed, or have means for fixing them in position, for better control over the movements of the container. In the embodiment illustrated in Figs. 7 to 14, the casters 29 at one end of the container are nxed, and the casters 28 at the opposite end are swivelled. This enables an operator not only to move the container about, but it can also be moved into the forks in the manner diagrammatically illustrated in Figs. -11 to 14. The open side of each of the lifting channels 26 enables vthe container to be pushed linto engaging relation with the forks 6, in the manner i the forks and take up for space between the ends of the container and the forks. They allow the container to .be

vshort enough to roll into vthe fork diagonally, without fequiring' unduly wide'pick-up channelsl 26'. It is desirabley to roll vinto the channels, in the manner illustrated.

Thecontainer may be provided with' a suitable or desirable closure means. shown at 30 in the bottom of the container. Filling openings may be provided in the top, or in the ends or sides thereof, and having the usual closure doors or lids therefor. We have shown the top as initially open and provided with closure lids 31, hinged at ,32 on a hinge rod that extends lengthwise of the bodyportion 25. The opposite ends of the hingerod 32 are supported in arms 33, secured to the opposite ends of the container.

The containers may be filled separate and apart from the hoisting `unit, or loader, according to theA several embodiments illustrated, and then either picked up by the loader or engaged therewith for dumping of the contents into the body of the vehicle. In the form shown in Figs. 1 to 6the container may be suspended by the loader several inches above the groundand carried thereby from place to place for dumping of refuse into the container as, for example, from house to house. When the container is :finally full, the swinging baffle 19 can be turned back against the refuse, -or this. may be done between-fillings. Then, when the container is filled, it may be lifted for dumping the'contents into the body. 1 1 The same practice may be followedfwith the form of container shown in Figs. 7 to l0, if the height of the container is such as will permit the material to be thrown into the container. However,}the latter is also capable of being moved into secure engagement with the forks 6 by rolling it between the -forks when the vehicle is stationary, after filling of the container, for dumping the contents into thebody of the vehicle. The swivelled rollers at one end of the container not only permit of adequate control for the movement of the container, but they enable the container to be moved into proper relation with forks, which latter engage the liftingchannels 26 through the open sides thereof. .n

While the invention has been illustrated and described in certain embodiments, it is recognized that other variations and changes may be made therein without departing from the invention as set forth in the claims.
