1. A semi-automated refuse vehicle, having a refuse receptacle, which vehicle comprises;

  • a. a wheeled frame, b. a substantially closed refuse body mounted on said wheeled frame, c. a source of fluid under pressure, d. a boom pivotally mounted on a side of said wheeled frame and being adapted to extend along a side of said frame, when in one position, which boom is mounted to move about a transverse axis, which axis is angularly inclined less than 90 degrees relative to the horizontal, so as said boom moves outwardly, the outer end thereof will be moved downwardly to engage a refuse container and, as the outer end of the boom moves inwardly, the outer end thereof will be moved upwardly to enable refuse to be discharged from the refuse container into a refuse receiving receptacle at a higher elevation, 1. a first fluid actuated cylinder-plunger assembly connected to said boom and to said frame to move said boom relative thereto, 2. conduit means leading from said source of fluid under pressure to the cylinder of said first fluid actuated cylinder-plunger assembly, 3. valve means within said conduit to seLectively direct fluid under pressure to one end of said first fluid actuated cylinder, when said valve is in one position, to move the plunger thereof in one direction and to direct fluid to the opposite end of said cylinder to move the plunger thereof in the opposite direction, when said valve is in another position, so as to move said boom selectively outwardly and inwardly, e. a pair of refuse container engaging arms on said boom near the outer end thereof, f. a second fluid actuated cylinder-plunger assembly mounted near the outer end of said boom and having one end thereof connected to said boom, the other end of said second fluid actuated cylinder-plunger assembly being connected to at least one of said arms to cause relative movement therebetween to grip the refuse container, 4. valve means, which, when in one position, directs fluid into one end of said second fluid actuated cylinder and directs fluid outward from the opposite end thereof to move at least one of said arms relative to said boom to engage the refuse container and said valve means, when moved to another position, directs fluid into the opposite end of said second fluid actuated cylinder, and out through the other end thereof to disengage said arms from the refuse container, g. tipping means associated with said boom to move said arms about the longitudinal axis of said boom to invert the refuse container, when said boom is in the inner-most position.
