Total Claims: 4
Claim 1
Independent Claim
180 words
Loading and sorting device for sawn timber, consisting of a conveyor from which are suspended hooklike members, on the support of which transportation of the pieces of timber is carried out and which are found on the conveyor in at least two parallel sequences separated by a distance, transportation of the pieces of timber taking place in transversal position with reference to the direction of travel of the conveyor characterized in that the hooklike member includes a shaft means part, against which the piece of timber (6) to be transported rests with one side of its cross section, and a movable retainer means provided beneath said shaft part, on the support of which the piece of timber to be transported rests with another side of its cross section and which has been arranged, when delivery of the piece of timber is made to occur, to move and withdraw to the opposite side of the shaft part, whereby support of the piece of timber is abolished and the piece of timber will be caused to fall down along the shaft part.
