Abstract
Abstract Apparatus for conveying and feeding pieces of wood or bulky items such as paper and cardboard boxes or the like to a cutting and punching type reduction device comprises a generally horizontal lower wide belt unit and a plurality of narrow upper belt units converging inwardly from a feed opening into that device. The belts define respective upper and lower sides of a feed passage moving in the same direction at the same speed. The narrow upper belt units are freely rockable about a common axis and all rest at their inner ends on the end of the wide belt adjacent the cutting and punching device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
Apparatus for feeding pieces of wood, paper or like material into a reduction device comprising upper and lower belt means converging inwardly from an inlet opening, said upper belt means comprising a plurality of side by side separate relatively narrow belt units and said lower belt means comprising a wide belt unit at least as wide as a plurality of said upper belt units, and means individually pivotally mounting said upper belt units (being individually pivoted) to rock independently about transverse axes at their uppermost ends at said inlet opening, and said upper belt units being distributed transversely of said lower belt unit and being adapted to permit said upper belt means to substantially conform to a contour of material on said lower belt unit.
Claim 2
Dependent Claim
125 words
Apparatus for feeding pieces of wood, paper or like material into a reduction device comprising upper and lower belt means converging inwardly from an inlet opening, said upper belt means comprising a plurality of side by side separate relatively narrow belt units and said lower belt means comprising a wide belt unit at least as wide as a plurality of said upper belt units, and means individually pivotally mounting said upper belt units (being individually pivoted) to rock independently about transverse axes at their uppermost ends at said inlet opening, and said upper belt units being distributed transversely of said lower belt unit and being adapted to permit said upper belt means to substantially conform to a contour of material on said lower belt unit.
Claim 3
Dependent Claim
125 words
Apparatus for feeding pieces of wood, paper or like material into a reduction device comprising upper and lower belt means converging inwardly from an inlet opening, said upper belt means comprising a plurality of side by side separate relatively narrow belt units and said lower belt means comprising a wide belt unit at least as wide as a plurality of said upper belt units, and means individually pivotally mounting said upper belt units (being individually pivoted) to rock independently about transverse axes at their uppermost ends at said inlet opening, and said upper belt units being distributed transversely of said lower belt unit and being adapted to permit said upper belt means to substantially conform to a contour of material on said lower belt unit.
Claim 4
Dependent Claim
125 words
Apparatus for feeding pieces of wood, paper or like material into a reduction device comprising upper and lower belt means converging inwardly from an inlet opening, said upper belt means comprising a plurality of side by side separate relatively narrow belt units and said lower belt means comprising a wide belt unit at least as wide as a plurality of said upper belt units, and means individually pivotally mounting said upper belt units (being individually pivoted) to rock independently about transverse axes at their uppermost ends at said inlet opening, and said upper belt units being distributed transversely of said lower belt unit and being adapted to permit said upper belt means to substantially conform to a contour of material on said lower belt unit.
Claim 5
Dependent Claim
45 words
Apparatus as defined in claim 1, wherein means is provided for driving both said belt means so that the lower flights of the upper belts move in the same direction and at about the same speed as the upper flight of said wide lower belt.
Claim 6
Dependent Claim
19 words
Apparatus as defined in claim 1, each of said upper belt units being swingablY mounted on a common axis.
Claim 7
Dependent Claim
34 words
Apparatus as defined in claim 3, said lower belt means comprising a single wide belt unit having a width substantially as great as the combined width of all of said upper narrow belt units.
Claim 8
Dependent Claim
32 words
Apparatus as defined in claim 4, wherein all of said narrow upper units may rest at their inner lower ends on said wide lower belt unit when there is no material therebetween
Claim 9
Dependent Claim
88 words
In the apparatus defined in claim 1, a common drive shaft upon which each of said upper belt units is pivoted, a plurality of spaced pulleys along said shaft one for each upper belt unit, each upper belt unit comprising a longitudinal member mounted for free rocking about the axis of said shaft and rotatably mounting a pulley on a transverse axis at the lowermost end of said member and an endless belt between each pulley on the shaft and the pulley on an associated upper belt unit.
Claim 10
Dependent Claim
24 words
In the apparatus defined in claim 6, means for adjusting the angularity of the transverse axis of the pulley on each of said members.
