Abstract
Abstract A grinder-feeding system including a log aligning device comprising a log-feeding box adapted to receive logs, and a conveyor including at least two power-driven upwardly sloping chains carrying a plurality of transverse cross pieces for receiving the logs from the feeding box and aligning such logs as they are moved up the slope by the chains. A butting wall is mounted parallel to the chains and on one side of the conveyor, and spiral rolls synchronized with the chains are mounted between each pair of chains for pushing the logs against the butting wall.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
95 words
A grinder-feeding system including an aligning device comprising: a. a log-feeding box adapted to receive log; b. a conveyor including at least two power-driven upwardly sloping chains carrying a plurality of transverse crosspieces for receiving the logs from the feeding box and aligning said logs while they are moved up the slope by the chains; c. a butting wall mounted parallel to said chains and on one side of said conveyor; and d. a spiral roll synchronized with said chains and mounted between each pair of chains for pushing said logs against said butting wall.
Claim 2
Dependent Claim
95 words
A grinder-feeding system including an aligning device comprising: a. a log-feeding box adapted to receive log; b. a conveyor including at least two power-driven upwardly sloping chains carrying a plurality of transverse crosspieces for receiving the logs from the feeding box and aligning said logs while they are moved up the slope by the chains; c. a butting wall mounted parallel to said chains and on one side of said conveyor; and d. a spiral roll synchronized with said chains and mounted between each pair of chains for pushing said logs against said butting wall.
Claim 3
Dependent Claim
18 words
A grinder-feeding system as defined in claim 1, wherein said crosspieces are separate pieces attached to each chain.
Claim 4
Dependent Claim
23 words
A grinder-feeding system as defined in claim 1, wherein said crosspieces consist each of a single piece attached to each of the chains.
Claim 5
Dependent Claim
43 words
A grinder-feeding system as defined in claim 1, wherein the slope of the chains and the height of the crosspieces are related to the height of the maximum diameter of the logs in order to prevent rolling back of the large diameter logs.
Claim 6
Dependent Claim
17 words
A grinder-feeding system as defined in claim 1, wherein the crosspieces are made of structural angle plates.
Claim 7
Dependent Claim
18 words
A grinder-feeding system as defined in claim 1, wherein the crosspieces are made of inverted V-shaped formed plates.
Claim 8
Dependent Claim
64 words
A grinder-feeding system as defined in claim 1, wherein each spiral roll consists of a smooth roll protruding slightly above the chain level in order to take off the weight of the logs from the chains so that the logs can be moved sideways against the butting wall tHrough the revolving action of the rolls, and a spiral ridge welded to each smooth roll.
Claim 9
Dependent Claim
60 words
A grinder-feeding system as defined in claim 7, wherein the pitch of the spiral ridge is exactly the same as the distance between two adjacent crosspieces, and wherein the highest point of the spiral at the top of the roll center is slightly in front of the crosspieces for catching protruding knots in the logs to easily move such logs.
Claim 10
Dependent Claim
22 words
A grinder-feeding system as defined in claim 1, further comprising a spiked roll conveyor for feeding the logs to said feeding box.
Claim 11
Dependent Claim
68 words
A grinder-feeding system as defined in claim 1, further comprising a first log ejector located at the top of the chain conveyor on one side thereof, a first conveyor chute located on the other side of said chain conveyor, and means for detecting any logs which are longer than a predetermined value and for actuating said first ejector to direct the long logs to the first conveyor chute.
Claim 12
Dependent Claim
60 words
A grinder-feeding system as defined in claim 10, further comprising a belt conveyor located at the output of said chain conveyor, a second ejector located on one side of said belt conveyor, a grinder metering gate located on the other side of the belt conveyor, and means for energizing said second ejector to direct said logs toward said metering gates.
Claim 13
Dependent Claim
95 words
A grinder-feeding system as defined in claim 10, further comprising a spiral roll aligning conveyor located at the output of said chain conveyor for receiving the logs which have gone passed the first ejector, a second log ejector located on one side of said spiral roll aligning conveyor, a second conveyor chute located on the other side of said spiral roll aligning conveyor, and means for detecting any logs which are larger in diameter than a predetermined value and for actuating said second ejector to direct the large diameter logs to the second conveyor chute.
Claim 14
Dependent Claim
42 words
A grinder-feeding system as defined in claim 12, further comprising a feed conveyor located at the output of said spiral roll aligning conveyor, grinder magazines located underneath said feed conveyor, and means including metering gates for dropping logs in said grinder magazines.
