Abstract
Abstract This application relates to a waste compressor particularly adapted for household or domestic usage which is powered by water pressure from a conventional water supply. The compressor incorporates a basket type frame in which a waste material carrying basket is slidably mounted, the basket forming the movable element for the compression motor and defining with the base of the casing, the expansion chamber for the compressor. A stationary die element removably connected to the top of the casing forms the cover such that as the basket is moved toward the die element waste material therebetween and in the basket is compressed.

Total Claims: 15
Claim 1
Independent Claim
363 words
A waste compressor comprising, an outer frame member having a thin curved upstanding wall section with a closed bottom section and an open top extremity with a uniform wall thickness and constant cross section intermediate the extent of the wall section, a basket member positioned in the outer frame member having a generally cup shaped configuration with an upper flange portion symmetrical with the inner cross section of the wall section of the frame member and with the remainder of the basket member having a reduced cross section from that of the upper flange portion thereof, said basket member having a recess open to the upper flange section with the basket member being slidably mounted in the outside frame member and defining an expansion chamber between the bottom of the basket member and the closed bottom section of the outside frame, seal means positioned on the upper flange portion of the basket member and bearing against the inner wall of the outer frame to provide a dynamic seal therebetween, a stationary die and cover member having a centrally located depending cup shaped die portion with a cross section symmetrical with the recess of the basket member, said stationary die and cover member having radially extending flange members adapted to fit into grooves in the upper edge of the outside frame member in suitable slots therein to secure the stationary die and cover member in said outside frame member and permit removal of the same, passage means positioned in the bottom of the outside frame and including valve means in the passage means, said passage means being adapted to be connected to a source of fluid under pressure with the valve means controlling flow of the fluid selectively into the expansion chamber to move said basket member within said outer frame member in a direction toward said stationary die and cover member to compact material positioned in the recess of the basket member, said valve means including means for providing a flow of fluid from said expansion chamber to an outside drain to permit the return of the basket member to a position in contact with the bottom section of the outside frame member.
Claim 2
Dependent Claim

A waste compressor comprising, an outer frame member having a thin curved upstanding wall section with a closed bottom section and an open top extremity with a uniform wall thickness and constant cross section intermediate the extent of the wall section, a basket member positioned in the outer frame member having a generally cup shaped configuration with an upper flange portion symmetrical with the inner cross section of the wall section of the frame member and with the remainder of the basket member having a reduced cross section from that of the upper flange portion thereof, said basket member having a recess open to the upper flange section with the basket member being slidably mounted in the outside frame member and defining an expansion chamber between the bottom of the basket member and the closed bottom section of the outside frame, seal means positioned on the upper flange portion of the basket member and bearing against the inner wall of the outer frame to provide a dynamic seal therebetween, a stationary die and cover member having a centrally located depending cup shaped die portion with a cross section symmetrical with the recess of the basket member, said stationary die and cover member having radially extending flange members adapted to fit into grooves in the upper edge of the outside frame member in suitable slots therein to secure the stationary die and cover member in said outside frame member and permit removal of the same, passage means positioned in the bottom of the outside frame and including valve means in the passage means, said passage means being adapted to be connected to a source of fluid under pressure with the valve means controlling flow of the fluid selectively into the expansion chamber to move said basket member within said outer frame member in a direction toward said stationary die and cover member to compact material positioned in the recess of the basket member, said valve means including means for providing a flow of fluid from said expansion chamber to an outside drain to permit the return of the basket member to a position in contact with the bottom section of the outside frame member.
Claim 3
Dependent Claim
40 words
The waste compressor of claim 1 in which the curved wall section of the outside frame member and the upper flange portion of the basket member are annular in cross section and the outside frame has a generally cylindrical configuration.
Claim 4
Dependent Claim
41 words
The waste compressor of claim 2 in which the valve means is a three-way valve having an input passage adapted to be connected to a source of water under pressure and an outlet passage adapted to be connected to a drain.
Claim 5
Dependent Claim
43 words
The waste compressor of claim 3 in which the seal means positioned on the upper flange member of the basket is an O-ring positioned in a groove therein and bearing against the inner wall surface of the outside frame member to seal therebetween.
Claim 6
Dependent Claim
22 words
The waste compressor of claim 1 in which the outside frame member and the basket member are made of a fiberglass material.
Claim 7
Dependent Claim
66 words
The waste compressor of claim 5 in which the recess in the basket member and a cup shaped depending portion of the stationary die and cover member are generally circular in cross section and inwardly tapered from top to bottom respectively to mate when the basket member is extended in the outeR cylindrical frame upwardly in near contacting relationship with the stationary die and cover member.
Claim 8
Dependent Claim
28 words
The waste compressor of claim 7 in which the stationary die and cover member includes handle means extending between flange members on the exposed surface of the same.
Claim 9
Dependent Claim
97 words
The waste compressor of claim 7 and including an additional passage in the bottom section of the outer frame member communicating with the expansion chamber and including a check valve means which is spring-biased to a closed position, said check valve means having a flexible connection to a movable element of the check valve means connected to the bottom of the basket member to open the check valve means as the basket member extends in the outside frame member to a predetermined upward position, said additional passage being connected through said valve means to the drain thereof.
Claim 10
Dependent Claim
19 words
The waste compressor of claim 8 and including plastic liner means positioned in the recess of the basket member.
Claim 11
Dependent Claim
54 words
The waste compressor of claim 9 in which the inner circular surface of the outer frame member adjacent the upper extremity thereof is recessed to permit escape of fluid from the expansion chamber with movement of the basket member into near contacting relationship with the flange members of the stationary die and cover member.
Claim 12
Dependent Claim
167 words
A waste compressor comprising, an outer cylindrical casing having a thin wall portion of uniform interior cross section and a closed bottom portion with an open top, a ram bucket positioned in the casing and having a guide flange near the open extremity of the same having a cross section similar to the interior cross section of the cylindrical casing to slidably mount the ram bucket therein and with a cylindrical recess extending from top to a closed bottom portion of the bucket, said flange section forming with the closed bottom portion of the casing an expansion chamber for moving the ram bucket, a cover and die section removably positioned in the upper portion of the casing and having a depending portion symmetrical with the recess in the ram bucket to compress material positioned in the ram bucket as the ram bucket moves upwardly in the casing, and a fluid inlet passage into the casing communicating with the expansion chamber and adapted to transmit expansion fluid thereto.
