Garbage compacting apparatus

Claim 2

Garbage compacting apparatus for compacting garbage within a receptacle, comprising a frame including an external sleeve, a slideable sleeve slideably mounted on said frame within said external sleeve, operating means operatively connected to said slideable sleeve for advancing and retracting said slideable sleeve respectively toward and from a wall of the receptacle, means for delivering garbage to within said slideable sleeve including access openings communicating with each of said external and slideable sleeves, and compaction means operatively associated with said slideable sleeve for compacting garbage within said slideable sleeve against said wall of the receptacle, said access opening in said slideable sleeve communicating with said access opening in said external sleeve when said slideable sleeve is in an advanced position, said slideable sleeve closing said access opening in said external sleeve when said slideable sleeve is in a retracted position.

Claim 3

Garbage compacting apparatus as claimed in claim 1 wherein said compaction means includes a piston slidably mounted within said slidable sleeve and power means for moving said piston along the longitudinal axis of said slidable sleeve.

Claim 4

Garbage compacting apparatus as claimed in claim 1 wherein said slidable and external sleeves have their longitudinal axis vertically oriented and said means for delivering garbage includes a horizontal sleeve having its longitudinal axis horizontally oriented, one end of said horizontal sleeve communicating with said access opening in said external sleeve.

Claim 5

Garbage compacting apparatus as claimed in claim 3 wherein said access openings in said slidable and external sleeves extend through the sidewalls thereof, said horizontal sleeve having an end thereof joined to said external sleeve surrounding said access opening in said external sleeve.

Claim 6

Garbage compacting apparatus as claimed in claim 4 wherein said means for delivering garbage includes a second piston slidably mounted in said horizontal sleeve and power means for moving said second piston along the longitudinal axis of said horizontal sleeve.

Claim 7

Garbage compacting apparatus as claimed in claim 5 wherein said means for delivering garbage includes a chute communicating with said horizontal sleeve through an access opening through the sidewall thereof, said second piston including a skirt overlying at least a portion of the internal wall of said horizontal cylinder whereby to close off said access opening through said horizontal cylinder when said second piston is in an advanced position.

Claim 8

Garbage compacting apparatus as claimed in claim 5 wherein the size and configuration of the surface of said second piston is substantially that of the size and configuration of said access opening in said external sleeve whereby to close said access opening in said external sleeve when said second piston is in an advanced position.

Claim 9

Garbage compacting apparatus for compacting garbage within a receptacle comprising a frame, an external sleeve mounted on said frame, a first access opening in the sidewall of said external sleeve, a slidable sleeve slidably mounted in said external sleeve, a second access opening in the sidewall of said slidable sleeve, said sidewall of said slidable sleeve overlying said first access opening to close off same when said slidable sleeve is in a retracted position, said second access opening communicating with said first access opening when said slidable sleeve is in an advanced position, operating means acting between said frame and said slidable sleeve for effecting advancement and retraction of said slidable sleeve with respect to said external sleeve, a piston movably mounted within said slidable sleeve, power means cooperating between said piston and said frame for moving said piston, and means for delivering garbage to within said slidable sleeve through said first and second access openings.

Claim 10

Garbage compacting apparatus for compacting garbage within a receptacle comprising a frame, an external sleeve mounted on said frame, a first access opening in the sidewall of said external sleeve, a slidable sleeve slidably mounted in said external sleeve, a second access opening in the sidewall of said slidable sleeve, said sidewall of said slidable sleeve overlying said first access opening to close off same when said slidable sleeve is in a retracted position, said second access opening communicating with said first access opening when said slidable sleeve is in an advanced position, operating means acting between said frame and said slidable sleeve for effecting advancement and retraction of said slidable sleeve with respect to said external sleeve, a piston movably mounted within said slidable sleeve, power means cooperating between said piston and said frame for moving said piston, and means for delivering garbage to within said slidable sleeve through said first and second access openings.

Claim 11

Garbage compacting apparatus as claimed in claim 8 wherein said last named means includes a fixed sleeve having an end thereof joined to said external sleeve, a third access opening in the sidewall of said fixed sleeve, a second piston movably mounted within said fixed sleeve, and second power means cooperating between said fixed sleeve and said second piston for moving said piston toward and from said first access opening.

Claim 12

Garbage compacting apparatus as claimed in claim 9 wherein said second piston includes a skirt extending in a direction away from said first access opening, said skirt overlying said third access opening when said second piston is moved toward said first access opening.

Claim 13

Garbage compacting apparatus as claimed in claim 9 wherein the size and configuration of the surface of said second piston is substantially that of the size and configuration of said first access opening.

Claim 14

Garbage compacting apparatus as claimed in claim 9 wherein the longitudinal axes of said external and slidable sleeves are substantially vertically oriented and the longitudinal axis of said fixed sleeve is substantially horizontally oriented.
