' Claims. (cram-116) I This invention relates to an apparatus especially suitable and useful for the disposal of refuse or the like and for the loading of the refuse into transporting vehicles such as trucks, or trailers or the like. It is quite generally appreciated that the maintenance of alleys or back drives or easements in a proper clean and sanitary condition isa problem of immense proportions. Even though the refuse be placed in proper receptacles or cans they are liable to be turned over so as to spill the refuse over the alley. Moreover, it requires a considerable crew of men to pick up the refuse and load the same into transporting vehicles as the receptacles, even assuming that the refuse is properly contained in the receptacles, have to be picked up and dumped into a vehicle body, the height of which may be in excess of six feet from the ground. One way this is accomplished is for the driver of the vehicle to drive down the middle of the alley while several men walk along each side of the alley to pick up the receptacles and dump the same into the vehicle.

The present invention aims to provide an improved receptacle and a lifting and dumping mechanism therefor. The receptacle is firmly held in position on a suitable base so that it is not liable to be turned over orotherwise mishandled so that the refuse will spill in the alley, and the structure involves a mechanism, which by a simple operation, makes it feasible for one Workman to operate so that the receptacle is elevated into a position overlying the vehicle and then tipped to discharge the contents thereof into the vehicle body. This reduces the number of men required and promotes discharge of the entire contents into the vehicle.

In accordance with the invention, the receptacle is mounted on a base structure which supports the elevating mechanism and. in the operation of this structure the receptacle is not only elevated but is moved angularly so as to overlie a vehicle stationed alongside of the receptacle. When the receptacle is properly elevated it is turned or swung to discharge the contents thereof. The receptacle may be used for any and all kinds of refuse or waste material whether it be ashes or food refuse or the like.

A structure made in accordance with the invention is diclosed in the accompanying drawings:

Fig. 1 shows the apparatus withthe receptacle in a positionabout to be actuated to discharge its contents into the vehicle body.

. l l 2 I r Fig. 2 is a side elevational view with the receptacle in its normal position.

Fig. 3 is an elevational view taken in a direction of line 33 of Fig. 2.

Fig. 4 is a view illustrating the construction for holding and manipulating the cover of the receptacle.

Fig. 5 is a somewhat diagrammatic view illus- The receptacle is illustrated at 4 having a cover 5 pivoted to the receptacle as at 6.

Associated with the receptacle is an elevating mechanism which, as shown in Figs. 1 and 2,, comprises a series of levers pivoted together at their intermediate portion and at their ends in such a manner that bya simple movement there is an extending action. This structure is commonly known as a lazy-tong structure and it will be referred to as such herein. As shown in Figs. 2 and 3 there are two sets of lazy-tongs, one on each side of the receptacle and they are generally illustrated at l0 and I I. Suitably mounted in the 4 base is a cross shaft [2 constituting the fixed end of the lazy-tong structure. As illustrated in Fig. 1 the lazy-tong structure I!) is comprised of a series of levers l3 and I4 pivoted together at their intermediate portions as at I5 and at their ends as at IS. The pivot points l5, however, are located so that some of the lever arms are longer than others. For example, the arms I! of the levers are longer than the arms l8 so that when the lazy-tong structure is extended the movement given to the can is upwardly and angularly. Thus, the receptacle is moved laterally, so that it may overlie a vehicle body. The lazy-tong structure II on the opposite side of the receptacle is constructed in the same manner. l

The mechanism for controlling the movement of the lazy-tong structure is housed in the covering 3 and is shown in Figs. 6 and 7. There is a worm 20 with an exposed end in the form of a nut or the like 2| adapted to receive a suitable tuming tool or wrench 22. The worm structure :meshes with the teeth of a worm gear 23 for turning s a main shaft 24 through the means of

gears

25 and 26. On this main shaft is a gear 21 and a gear 28 and the teeth of these gears mesh with gears or

pinions

29 and 36. The axial extent of gear 29 and, 3B exceed that of

gears

21 and 28 as shown in Fig. 6. The two lowermost lever arms I! and it have, as shown in Fig. 7, extending

segments

35 and 36. The Segment 35 joins with arm is and its teeth mesh with those of gear 29. The segment 36 joins with lever arm I! and its teeth mesh with the gear 2?. In this manner the dithe receptacle approaches its lowermost position rection of oscillation of the levers is made to be clockwise as Fig. 7 is viewed, the arm H is rocked counter-clockwise. At the same time the gear 29 is rotated counter-clockwise and the segment and arm is are rocked clockwise. This gear arrangement is duplicated for the gears 28 and 3t and the 'lazy' ton'g set i 5. So it will be seen that by applying the turning tool to the operating piece 2| that the lazy-tong structure may be'extended or retracted. A modified form of operator is shown in Fig. 3. In this form a lever 40 is operable on the shaft is and the lazy-tong structure advanced or retracted by swinging of the lever. This modified arrangement may be suitable for smaller installations. However, the worm-type of mechanism is irreversible so that the structure, when extended, will remain in extended position.

The receptacle'is pivotally mounted to the lazytong structure as at 4|. This mounting is advantageously a little bitabove the center of gravity. On one of the pintles attached to the receptacle is a spring retainer 42 for cooperation with a coil spring 43, oneend of which is attached tothe retainer at 4 and the other end of which isattached to the lazy-tong structure at one of the fulcrum points, for example, as illustrated at .45. The member $2 is rigid with the container and when the receptacle is in lowered position the spring is more or less wound around the retainer 42.

" Mounted on the receptacle is a channel 56, one

side of which near the bottom may be cut away as at 5|. Near the top of the channel is an opening 52. Adjacent the opening 52 is an angular guide 53. At one of the fulcrum points in the lazy-tong structure, for example, at the point 55 there is a projecting stud 56 designed to cooperate with the channel 5E The spring arrangement and the channel and stud arrangement cooperate to control the tipping action of the receptacle.

I The structure operates as follows: In the nor mal position of repose the receptacle may rest upon the base with the lazy-tong structure collapsed as shown in Figs.2 and 3. The spring 42 is wrapped upon the retainer; the stud 56 reposes in the upper part of the channel 59 substantially as illustrated in'Fig. 5. To elevate the container the operating piece 2| is rotated which may be done by means of a suitable handle or crank 22. This actuates the gearing as shown in Fig.7 and as previously described, and the lazy-tong structure is extended. 'As the container is elevated the pivot point 55 and the stud 55 move downwardly relative to the point of connection 4| with the receptacle and, therefore, the stud moves downwardly in thecha-nnel 55: At the same time, the spring 43 is'stressed. As will be appreciated by reference to Fig. 1, the spring retainer 42 acts as a lever, and

the spring; places the torque on the receptacle tending to turn it on its mountings 4| in a 'coun:

' tor-clockwise 'direction'asFig. 1 is viewed. However,--thi's'-cannot occur-because the" pin 56 lies in may gravitate back to its normal vertical position. When this is done the pin 56 is outside the channel 50 but below the angle guide 52. It may be that the receptacle, in gravitating to a vertical position, will cause the opening 52 to move over the pin. For safety purposes, however, and in the event this does not occur, the pin 56 will strike the angle guide 56 and thereby be forced into the channel- Thus, the parts are restored to the positions-shown .in Fig. 5.

The cover of the receptacle is preferably mounted so that theirece'ptacle is opened by the cover and tips to the dotted line positions shown in Fig. 1. To this end there is a cover operator pivotally secured to the cover. as at, 6i and piv: otaily connected at a relatively fixed point v$2.

The operator is a telescoping structure residing there is a sort of rocker arm having a part 10 and a part l2'pivotally mounted as at 73 on one of the lazy-tong levers. A link 15 is pivotally mounted asat'ifi on an opposite lazy-tong lever.

and the link 15 is pivoted to thepart 'EZfas 'at 17. Whenthe receptacle tips about its pivotal mounting ti the strut of thecover pivots about the point 62. Since point 62 is removed from the pivot point 4!, the hinge 6 of the cover and the point of connection 5i move about different arcs. The link structure tit-64 provides a strut action and causes the cover to swing intoan open posi-, tion shown by the dotted lines in Fig. 1. Due to the link structure 16-12, and '55, the point 62 remains relatively fixed as regards the pivot point ll. That is to say, the pivot point 62 remains at substantially the same radial distance from the pivot point. As the lazy-tong levers collapse, as shown by the dotted lines in Fig. 4, thereis a hinging action as at 71 between the parts l5'and 12 and this leversystem is worked out to maintain the point 62 at approximately a uniform distance from the center 4|. Accordingly, when the receptacleis lowered and gravitates toward normal position the cover will, by gravity, assume a closed position. 7 The cover may be lifted on its hinge with the telescoping parts 63 and 64 sliding relative to each other. The structure comprising the part 63 and 64 ma if desired, be arranged to hold the cover open when refuse is being placed in the con tainer. Such, structures. are known to those versed in the art oflids and decks and constitutes a refinement which may be made in a commercial structure but which needs no detail description herein.
