Abstract
Abstract Debris is picked up by equally angularly spaced brushes. Each brush is arranged in a helix for cooperation with a plurality of stripper bars. The helix causes the brush to engage the end of only one of the stripper bars at a time during rotation to reduce the shock load on the stripper. Each brush can have a row of tines adjacent thereto with the rows of tines being equally angularly spaced.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words
An apparatus for collecting debris including: a frame having wheels to support said frame; a housing supported by said frame; said housing having compression means to compress debris received by said housing; and debris pick-up means rotatably supported by said frame to pick up debris for supply to said housing for compression; said debris pick-up means including: support means for rotation about a substantially horizontal axis; means to rotate said support means; said support means having a plurality of brushes supported thereon and angularly spaced from each other about the axis of rotation; each of said brushes being formed in a helix; stripping means supported by said frame for cooperation with each of said brushes separately to strip debris therefrom just prior to the debris enterinG said compression means; and said stripping means having a plurality of spaced stripper bars, each of said stripper bars having its end engaged by one of said brushes separately, and each of said brushes engaging the ends of all of said stripper bars during rotation of said brushes prior to the next of said brushes engaging the end of any of said stripper bars.
Claim 2
Independent Claim
190 words
An apparatus for collecting debris including: a frame having wheels to support said frame; a housing supported by said frame; said housing having compression means to compress debris received by said housing; and debris pick-up means rotatably supported by said frame to pick up debris for supply to said housing for compression; said debris pick-up means including: support means for rotation about a substantially horizontal axis; means to rotate said support means; said support means having a plurality of brushes supported thereon and angularly spaced from each other about the axis of rotation; each of said brushes being formed in a helix; stripping means supported by said frame for cooperation with each of said brushes separately to strip debris therefrom just prior to the debris enterinG said compression means; and said stripping means having a plurality of spaced stripper bars, each of said stripper bars having its end engaged by one of said brushes separately, and each of said brushes engaging the ends of all of said stripper bars during rotation of said brushes prior to the next of said brushes engaging the end of any of said stripper bars.
Claim 3
Dependent Claim
93 words
The apparatus according to claim 1 in which: a plurality of rows of tines is mounted on said support means; each of said tines in each of said rows is disposed relative to said stripper bars so that each of said tines passes between adjacent of said stripper bars during rotation of said tines; each of said rows of said tines is disposed adjacent one of said brushes; and each of said rows of said tines is formed with the same helix as said brush to which said row of tines is adjacent.
Claim 4
Dependent Claim
28 words
The apparatus according to claim 2 in which each of said rows of said tines trails said adjacent brush in the direction of rotation of said support means.
Claim 5
Dependent Claim
33 words
The apparatus according to claim 3 in which said brushes are equally angularly spaced about the axis of rotation and said rows of tines are equally angularly spaced about the axis of rotation.
Claim 6
Dependent Claim
25 words
The apparatus according to claim 4 in which the tips of said tines and the tips of said brushes are in the same rotary path.
Claim 7
Dependent Claim
33 words
The apparatus according to claim 2 in which said brushes are equally angularly spaced about the axis of rotation and said rows of tines are equally angularly spaced about the axis of rotation.
Claim 8
Dependent Claim
78 words
The apparatus according to claim 1 in which: a plurality of rows of tines is mounted on said support means; each of said tines in each of said rows is disposed relative to said stripper bars so that each of said tines passes between adjacent of said stripper bars during rotation of said tines; and each of said rows of said tines is disposed between two of said brushes and is spaced angularly from each of said brushes.
Claim 9
Dependent Claim
33 words
The apparatus according to claim 7 in which said brushes are equally angularly spaced about the axis of rotation and said rows of tines are equally angularly spaced about the axis of rotation.
Claim 10
Dependent Claim
36 words
The apparatus according to claim 8 in which each of said rows of said tines is an equal angular distance from each of said brushes between which each of said rows of said tines is disposed.
Claim 11
Dependent Claim
19 words
The apparatus according to claim 1 in which said brushes are equally angularly spaced about the axis of rotation.
