2 Claims. (Cl. 214-2) This invention relates to a garbage packing box or receptacle and more particularly to a garbage and trash collecting box to collect, pack and discharge refuse or garbage speedily and efficiently with great ease and controlled automatically by the operator of the device.

An object of this invention is to provide a garbage packing box of this kind which may be mounted on a truck or other mobile unit for transporting the box from one piace to another for collecting the refuse and for transporting the box and refuse therein to a place where the refuse may be emptied from the box.

Another object of this invention is to provide a garbage packing box of the kind to be more particularly described hereinafter which is hydraulically actuated for removing the refuse from the box when it is desired to do so and in a selected area.

Other and further objects and advantages of the invention will be hereinafter described and the novel features thereof defined in the appended claims.

Fig. 12 is a diagrammatic view of the cylinder, piston, pusher blade and blade actuating cables.

Referring more particularly to the drawings the numeral 15 designates generally a refuse collecting and automati cally discharging truck constructed and arranged according to an embodiment of my invention. The truck 15 is used for collecting garbage or other refuse about a city and discharging such refuse at a selected location where it would be customary to pile up the refuse and further dispose of it.

The refuse collecting and automatically dumping truck 15 is provided with a box or body 16 which is securely mounted on the rear end of a truck 17 so that the collecting and discharging truck may be readily moved from one place to another.

2,753,057 Patented July 3, 1956 The truck body 16 is mounted on the rear end of the truck frame 18 rearwardly of the truck cab 19.

By this disposition of the truck body or box 15 on the truck 17 the body 16 is provided with a sliding panel 2t) at the forward end thereof which may be opened to receive therethrough the refuse which is placed within the body 16 at the time that it is collected. Handles 21 are secured on each of the sliding panels 2G for the proper manipulation thereof.

Interiorly of the box or body 16 there is provided a movable wall or pusher blade 22 which is movable along the length of the body by the hydraulic means to be hereinafter described. The lower end of the wall or pusher blade 22 is curved rearwardly as clearly noted in the drawings and designated by thefnumeral 24. ln order to provide for the smooth and proper movement of the pusher blade or wall 22 wheels 25 are rotatably mounted at the lower ends thereof for engagement on the upper surface of the bottom of the body 16, the wheels 25 being rotatably carried by a wheel bracket 26 which is secured to the lower end of the movable wall 22.

The movable wall or pusher blade 22 is moved forwardly of the body 16 by a cable 27 which is secured to the front side of the pusher blade, the cable 27 being trained about the periphery of a sheave 28 rotatably supported on the forward end of the box 16. A somewhat similar cable 29 is secured at one end to the rear side of the pusher blade 22 for pulling the pusher blade toward the rear end of the box 16.

Two such cables 29 are employed as ordinarily the force for moving the blades 22 rearwardly in the body is greater than the force necessary for moving the blade toward the front end of the body. By so positioning and locating the cables 29 on the pusher blade 22 an even tension may be employed for pulling the pusher blade in a balanced condition toward the rear of the body and moving with the pusher blade all of the material disposed within the body.

Sheaves 30 are rotatably supported on the outer side of the box over which the

cables

27 and 29 may be separately and individually trained.

ln order to automatically and hydraulically move the blade 22 longitudinally of the body 16 there is provided a cylinder 31 which is fixed on the outer side of the body 16 having a piston 32 therein which is slidable in two directions in the cylinder 31 for moving the blade 22 tothe front and rear end thereof.

The piston 32 has a longitudinally extending piston rod 34 secured thereon and the outer end of the piston rod 34 is provided with a cross shaft 35 exteriorly of the cylinder 31. The piston rod 34 engages the cross shaft 35 inten mediate the length thereof and sheaves 36 are rotatably secured to each outer end of the cross shaft for disposing these sheaves transversely of the piston rod 34.

As the

cables

27 and 29 are trained about the sheaves 36 and are secured at one end to the pusher blade, the other end of each of the cables is anchored by way of a spring 37 to the cylinder adjacent the end thereof opposite to the end from which the piston rod 34 extends.

As the piston 32 is hydraulically actuated there is provided a hydraulic tank 46 on the truck 17 for hydraulic fluid and a pump 41 is mounted adjacent to the hydraulic tank 40 and communicated therewith with a pump inline 42 so that the pump may take the fluid from the tank to the cylinder 31 where it is to be used for actuating the piston 32 in either a forward or rearward direction. The direction of the movement of the piston 32 is controlled by a valve 44 having a rotatable core 45 therein, the core 45 being provided with a pair of outwardly opening passages or openings 47 therein so that the pressure Vline 46 from the pump to the Valve will always be actuated regardless of the position of the core 45.

A tube 48 is connected between the valve 44 Vand the front end of the cylinder rwhile a similar tube 49 is connected between the rearv end of the cylinder and the valve 44fso that the direction ofk movement of `the piston 32 depends` upon thev particular `position of the core 45 in the valve 44.

An arm 50v isxedly secured to one end of the core 45 for properly rotating the core to theposition selected andy the actuating arm 50 is drawn in one direction by a spring 51 so that the pusherblade 22 will be moved to the front end of the body 16 by themovement `of the piston in the cylinder which will actuate the

cables

27 and 29.

A control valve 52 is communicated with the valve 44 havingv a pressure cylinder'53 with a 4piston 54 slidable therein. The piston 54 has a piston rod 55 secured thereto and a` spring 56 will urge the piston 54 downwardly in the cylinder 53.

An arm 57 is pivotally connected at one end thereof to the arm 50, intermediate the length of the arm 50 and spaced from the valve 44. The arm 57 has a notched latch 58 therein which `includes a notch` 58 which is releaseably engageable with akeeper `59 which is secured to the body 16 adjacent to the valve 44. The keeper 59 is provided with an opening 60 therethrough through which the arm 57 is freely slidable.

An elongated rod 61 is pivotally connected to the upper or outer end of the control arm 50 for manually moving the control arm t) and the core 45 to a position where the hydraulic pressure developed in the pump is employed` for moving the movable wall 22 toward the forward end of the body 16.

A rear door 62 is mounted at the rear end of the body 16 for closing a discharge opening at the rear end of the box. The door 62 is secured .in its closed position by a lock 63 which is carried by the door and will keep any material from being loosely scattered from the rear end of the truck.

A clutch 64 is used for holding the pump in action or out of action and this vclutch is heldin: action by a spring 65 which presses together the clutch plate thereof and the clutch plate may be disengaged when the pusher blade 22 is at the front end of the body 16 and no further movement is desired for the movable wall 22.

When the clutch 64 is disengaged the liquid is free for movement both in the pump inline 42 and in the discharge pipe 66 which is connected between the tank 40 andthe valve 44. The discharge pipe 66 may also be utilized at the time when the pump 41 is pumping pressurized fluid in the pump inline 42 and the valve 44 is turned to a position where it is not necessary to further move the piston 32 in the .cylinder 31.

In the use and operation ofthe refuse collecting and automatic discharge truck the pusher blade will be moved to the forward end of the empty truck and the refuse collected may be inserted into the body of the truck through the openings. adjacent to the front end whereupon by rearward movement of the pusher blade toward the rear of the body the material contained within thebody will be packed between the front and rear walls thereof. When sutiicient pressure has been built up to discharge the material through the rear opening closed bythe rear door 62, the rod 61 is pulled rearwardly to locate the arm-50 and thus` position the core of the valve 44 so' that the pressure developed by the pump 41 will be led to the rear end of the cylinder 31. When suflicient pressure hasbeen developed in the line 46, passage 47 and in the cylinder 53 the piston 54 will be urged upwardly for rocking the arm 57 upwardly to disengage the notch 58 from its keeper 59. At this time the spring will turn the valve core 45 to a position for reversing the movement of the movable wall or pusher blade 22 to the forward end of the truck. In this way the movable wall will be automatically hydraulically operated to the forward end of the tank after the material within the body has been fully packed or discharged out of the opening closed by the rear door.

While the specific details of one embodiment of this invention have been herein shown and described, the invention is not confined thereto aschanges and alterations may be made without departing from the spirit and scope thereof as defined in the appended claims.
