Claim 1
Independent Claim
214 words
In lawn grooming equipment in which lawn grooming means are mounted within a main body adapted to be moved over the surface to be groomed, which grooming means are driven to generate a flow of refuse material picked up from the lawn into a compacting device connected to said main body, said compacting device comprising a conveyor which rotates within a housing to convey the refuse material from a material inlet end to a material outlet end therein, the improvement comprising: (a) a conveyor housing surrounding a solid type compacting screw conveyor rotating therein to convey the refuse material while compressing it progressively therein as it is advanced through said housing from said material inlet to said material outlet end; (b) perforations in the wall of said conveyor housing for evacuating accompanying air and moisture from the refuse material during the compression step; and (c) a tubular casing extensibly connected to the outlet opening of said conveyor housing for receiving the initially compacted refuse material and allowing it to expand against the tubular wall thereof to plug one end thereof and thus cause the casing and the enclosed compacted refuse material to advance like a sausage from said outlet end under the force of the continuous advancement of refuse material from said conveyor housing.

In lawn grooming equipment in which lawn grooming means are mounted within a main body adapted to be moved over the surface to be groomed, which grooming means are driven to generate a flow of refuse material picked up from the lawn into a compacting device connected to said main body, said compacting device comprising a conveyor which rotates within a housing to convey the refuse material from a material inlet end to a material outlet end therein, the improvement comprising: (a) a conveyor housing surrounding a solid type compacting screw conveyor rotating therein to convey the refuse material while compressing it progressively therein as it is advanced through said housing from said material inlet to said material outlet end; (b) perforations in the wall of said conveyor housing for evacuating accompanying air and moisture from the refuse material during the compression step; and (c) a tubular casing extensibly connected to the outlet opening of said conveyor housing for receiving the initially compacted refuse material and allowing it to expand against the tubular wall thereof to plug one end thereof and thus cause the casing and the enclosed compacted refuse material to advance like a sausage from said outlet end under the force of the continuous advancement of refuse material from said conveyor housing.
Claim 3
Dependent Claim
29 words
Lawn grooming equipment according to claim 1, further comprising means for guiding a length of said sausage along a track on the main body of the lawn grooming equipment.
Claim 4
Dependent Claim
33 words
Lawn grooming equipment according to claim 1, in which said conveyor housing and said compacting screw conveyor are tapered so as to compress the refuse material in a ratio between 1:5 and 1:10.
Claim 5
Dependent Claim
40 words
Lawn grooming equipment according to claim 1, in which the inlet portion of the compacting housing is connected to a suction device to create an air stream whereby refuse material is drawn from the lawn in to the compacting conveyor.
Claim 6
Dependent Claim
30 words
Lawn grooming equipment according to claim 1, in which said conveyor housing and said screw conveyor are cylindrical and extend from the material inlet end to the material outlet end.
Claim 7
Dependent Claim
35 words
Lawn grooming equipment according to claim 1, in which said conveyor housing and said compacting screw conveyor comprise a cylindrical portion at the inlet end merging with a conical portion tapering towards the outlet end.
Claim 8
Dependent Claim
61 words
Lawn grooming equipment according to claim 1, further comprising a sprocket wheel having teeth contoured to conform to the flights of said compacting conveyor screw mounted in a slot defined in the wall of said conveyor housing to rotatably engage said screw flights to thereby prevent the refuse material from turning with the conveyor screw during the advancement and compression thereof.
Claim 9
Dependent Claim
27 words
Lawn grooming equipment according to claim 1, comprising a stud connected to said material outlet for further compression of collected refuse and for supporting said tubular casing.
Claim 10
Dependent Claim
16 words
Lawn grooming equipment according to claim 8, in which said stud has an outwardly flaring bore.
Claim 11
Dependent Claim
38 words
Lawn grooming equipment according to claim 1, further comprising a bore defined in said conveyor housing and in said compacting conveyor screw for transporting a fluid into a region proximate to the outlet end of the conveyor housing.
Claim 12
Dependent Claim
24 words
Lawn grooming equipment according to claim 9, wherein said fluid comprises a chemical substance adapted to react with the refuse material to form compost.
Claim 13
Dependent Claim
17 words
Lawn grooming equipment according to claim 10, further comprising means for supplying said fluid to said bore.
