Abstract
A vertically extending framework having a hydraulic ram subassembly mounted in the framework for pivotation about a horizontal axis, and spaced from the lower end of the framework to accommodate a refuse receptacle within the framework under the ram. A disinfectant injection pump is mounted in the hydraulic ram for automatically discharging a disinfectant into refuse compressed by the ram. The ram is double acting, and valve means is provided for automatically retracting the ram when a predetermined force opposes the outward extension of the piston of the ram.
Claims18
A refuse compacting apparatus comprising:
- a fluid powered ram including a cylindrical housing and piston means extensible from the housing;
- means for supporting the ram in a vertically elevated position to facilitate compaction of refuse positioned therebelow;
- an injection pump including:
- an injection pump sleeve connected to said piston means and movable therewith relative to said cylindrical housing;
- and
- an elongated tube projecting concentrically into said sleeve and connected to said cylindrical housing for retention in a fixed position as said sleeve moves relative to said housing;
- and
- a body of sanitizing additive liquid retained in said housing and communicating with the interior of said elongated tube.

A refuse compacting apparatus comprising:
- supporting means;
- a fluid powered ram supported on said supporting means in a vertically elevated position to facilitate compaction of refuse positioned therebelow, said fluid powered ram including:
- a cylindrical housing pivotally mounted on said supporting means for pivotation about a horizontal axis;
- a stationary partition plate in said cylindrical housing and partitioning said housing by extension thereacross;
- a centrally apertured end plate positioned in said housing and extending parallel to, and spaced from, said stationary partition plate;
- an internal piston plate reciprocably mounted in said cylindrical housing and positioned between said partition plate and end plate;
- a piston rod connected to, and movable with, said piston plate and projecting through the central aperture in the end plate and from said cylindrical housing;
- and
- a compacting piston plate secured to the end of said piston rod outside said housing;
- and

8 more elements
A refuse compacting apparatus comprising:
- a double acting hydraulic ram including an internal piston;
- frame means for supporting the ram in a vertically elevated position to facilitate compaction of refuse positioned therebelow;
- valve means for alternately charging a hydraulic fluid to opposite sides of said internal piston to actuate said ram and reverse the stroke of said internal piston, said valve means including shiftable piston means;
- an air accumulator connected to said valve means and defining a space adjacent the piston means of said valve means in one position of said valve means;
- and
- conduit means for receiving hydraulic fluid from said valve means when said valve means is in said one position and for delivering hydraulic fluid to said space to compress air in said space.
