Abstract
Abstract A method and apparatus is described for the handling of waste material, refuse and the like. Such waste material is normally deposited in large sized trash cans each of which are provided with an opening located near the closed bottom end thereof. A mobile unit is provided with suction generating means coupled to a flexible elongated hose of relatively large diameter. The flexible elongated hose, preferably of a corrugated type, has an outwardly directed flange spaced inwardly from its free end and adapted to be seated upon the upper circular edge of a trash can with the marginal portion of the free end of the hose protruding slightly into the interior of the can. Energization of the suction generating means enables the contents of the refuse container to be easily and rapidly removed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
254 words
A flexible hose for use in a vacuum type refuse collection system comprising: a tubular carcass portion and a flange portion spaced inwardly from one end of said carcass portion, said one end terminating in a cylindrical shaped section extending away from said flange; said carcass portion comprising a rubber body with reenforcing fabric embedded therein, said flange portion comprising molded resilient rubber and reenforcing means embedded therein, said flange portion comprising a rear flat annular surface portion extending radially outward relative to the axis of said hose, a circumferential portion extending parallel to the axis of said hose and an annular front surface portion extending at an angle to the axis of said hose, said reenforcing means comprising an annular metal member of right angle cross-section, one arm of said member extending parallel to the inner surface portion of said flange portion and extending beyond said annular front surface and into said cylindrical shaped section, the other arm of said member being concentric with the axis of said hose with the free end thereof extending toward the front surface portion of said flange portion; a first annular filler of concentric layers of fabric being wrapped about the outer surface of said other arm of said annular metal member; a second filler of annular shaped layers of fabric positioned so that said first layers and the free end of said other arm lies to one side of said second filler and said front surface portion lies on the opposite side of said second filler.
Claim 2
Dependent Claim
254 words
A flexible hose for use in a vacuum type refuse collection system comprising: a tubular carcass portion and a flange portion spaced inwardly from one end of said carcass portion, said one end terminating in a cylindrical shaped section extending away from said flange; said carcass portion comprising a rubber body with reenforcing fabric embedded therein, said flange portion comprising molded resilient rubber and reenforcing means embedded therein, said flange portion comprising a rear flat annular surface portion extending radially outward relative to the axis of said hose, a circumferential portion extending parallel to the axis of said hose and an annular front surface portion extending at an angle to the axis of said hose, said reenforcing means comprising an annular metal member of right angle cross-section, one arm of said member extending parallel to the inner surface portion of said flange portion and extending beyond said annular front surface and into said cylindrical shaped section, the other arm of said member being concentric with the axis of said hose with the free end thereof extending toward the front surface portion of said flange portion; a first annular filler of concentric layers of fabric being wrapped about the outer surface of said other arm of said annular metal member; a second filler of annular shaped layers of fabric positioned so that said first layers and the free end of said other arm lies to one side of said second filler and said front surface portion lies on the opposite side of said second filler.
Claim 3
Dependent Claim
40 words
A hose as in claim 1 wherein said reenforcing means further includes reenforcing cord fabric having end portions thereof embedded in said carcass portion and an intermediate portion encircling said annular metal member, to said first and second annular fillers.
Claim 4
Dependent Claim
37 words
A hose as in claim 1 wherein the free end of the second mentioned arm of said annular metal members extends to a position intermediate the annular edges of said front surface portion of the flange portion.
Claim 5
Dependent Claim
33 words
A hose as in claim 2 further comprising a wire helix embedded in said carcass portion between the inner and outer surfaces thereof and being wrapped around said reenforcing cord fabric end portions.
Claim 6
Dependent Claim
23 words
The hose of claim 1 wherein the layers of said first and second annular fillers are disposed at right angles to one another.
Claim 7
Dependent Claim
14 words
The hose of claim 1 wherein the major portion of said carcass is corrugated.
Claim 8
Dependent Claim
24 words
The hose of claim 6 further comprising helical reenforcing means extending along the entire corrugated portion of said hose and embedded in said carcass.
Claim 9
Dependent Claim
244 words
A flexible flanged hose construction comprising a tubular carcass portion including an elastomeric body and fabric reenforcing embedded therein, and a flanged portion spaced inwardly from one end of said tubular carcass portion, said one end terminating in a cylindrical shaped section extending away from said flange; said flange portion comprising an inner end surface disposed at right angles to the axis of said hose, a circumferentially extending outer surface disposed parallel to the axis of said hose, and an outer end having a surface extending at an angle to the axis of said hose, and reenforcing means embedded in said flange portion, said reenforcing means comprising a ring-shaped member of angular cross-section, one arm of said ring-shaped member being disposed adjacent the inner end surface of said flange portion, the other arm of said ring-shaped member being parallel to the axis of said hose and extending beyond said flange substantially along the entire length of said cylindrical shaped section, the free annular edge of said other arm of the ring-shaped member extending toward the outer surface portion of said flange portion, an annular filler of rubberized fabric disposed between the arms of said ring-shaped member, and cord fabric embedded in said carcass and flange portions, said cord fabric including first and second portions disposed adjacent one another and lying near the inner surface of said tubular carcass portion and an intermediate portion encircling said annular filler and the arms of said ring-shaped member.
Claim 10
Dependent Claim
