Abstract
Abstract A device for distributing pieces of wood to the feed chutes of a plurality of consecutively placed wood shredders from a hauling track composed of a plurality of consecutively arranged belt, chain or rope conveyors, upon which the pieces of wood have been arranged, in transverse position, to be transferred from one conveyor to another for distribution to the feed chutes through intervals of the conveyors, which are continuously open and filled with wood. According to the invention the conveyors have, moreover, been arranged to start automatically at predetermined intervals in a direction opposite to the wood feeding direction for a period which is shorter than the running time in the feeding direction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
An arrangement for distributing pieces of wood into feed chutes of a plurality of consecutively located wood processing stations comprising, in combination, a plurality of conveyors spaced from each other by predetermined gaps and carrying pieces of wood transferred from one conveyor to the neighboring conveyor in sequence; feed chute means in said gaps between said conveyors for receiving pieces of wood from said conveyors; wood processing means at the ends of said feed chute means and fed with wood from said chute means, the quantity of wood in said chute means decreasing during operation of said processing means for processing wood consumed from said chute means; means for operating said conveyors periodically for predetermined time intervals in a forward feeding direction to replace the wood consumed from said chute means by said processing means; and means for operating said conveyors periodically for predetermined time intervals in a reverse direction for substantially inhibiting accumulation of pile-ups of wood at said chute means feeding said processing means.
Claim 2
Dependent Claim
166 words
An arrangement for distributing pieces of wood into feed chutes of a plurality of consecutively located wood processing stations comprising, in combination, a plurality of conveyors spaced from each other by predetermined gaps and carrying pieces of wood transferred from one conveyor to the neighboring conveyor in sequence; feed chute means in said gaps between said conveyors for receiving pieces of wood from said conveyors; wood processing means at the ends of said feed chute means and fed with wood from said chute means, the quantity of wood in said chute means decreasing during operation of said processing means for processing wood consumed from said chute means; means for operating said conveyors periodically for predetermined time intervals in a forward feeding direction to replace the wood consumed from said chute means by said processing means; and means for operating said conveyors periodically for predetermined time intervals in a reverse direction for substantially inhibiting accumulation of pile-ups of wood at said chute means feeding said processing means.
Claim 3
Dependent Claim
34 words
The arrangement as defined in claim 1 wherein said predetermined time intervals when operating said conveyors in reverse direction are substantially shorter than said time intervals when operating said conveyors in forward feeding direction.
Claim 4
Dependent Claim
28 words
The arrangement as defined in claim 1 wherein each of said time intervals when operating said conveyors in forward feeding direction is of the order of several seconds.
Claim 5
Dependent Claim
26 words
The arrangement as defined in claim 1 wherein said conveyors are operated in reverse direction following each operation of said conveyors in The forward feeding direction.
Claim 6
Dependent Claim
22 words
The arrangement as defined in claim 1 wherein the travel of the conveyor in said reverse direction increases toward the end conveyor.
Claim 7
Dependent Claim
27 words
The arrangement as defined in claim 1 wherein said feed chute means comprises feed chutes having cross-sectional area increasing in magnitude in direction toward said processing means.
Claim 8
Dependent Claim
16 words
The arrangement as defined in claim 1 wherein said wood processing means comprises wood grinding means.
Claim 9
Dependent Claim
21 words
The arrangment as defined in claim 1 wherein said pieces of wood comprise logs of wood arranged transverse on said conveyors.
