Abstract
Abstract Pulpwood is fed from a vibratory table to a drum with grips which deposits the pulpwood onto a first guide in turn transferring the pulpwood to a conveyor which transports the pulpwood to a second guide, in turn transferring the pulpwood to a conveyor for charging defiber magazines. Both guides include displaceable members which are moved when pulpwood is present in the guides and these members act on respective switches which deactuate the drive of the preceding drum and conveyor respectively. Thus, when the first guide is loaded with pulpwood, the drum is at rest and when the second guide receives pulpwood from the first conveyor, the drive of the latter is terminated until the pulpwood has been transferred from the second guide to the conveyor for the defiber magazines.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
Apparatus for feeding pulpwood to a charging conveyor for the supply of pulpwood to defibre magazines, said apparatus comprising a vibratory table for pulpwood, conveyor means for feeding pulpwood from the table towards the charging conveyor, drive means for said conveyor means, displaceable guide means for receiving pulpwood from the conveyor means and moving to a displaced position under the weight of the pulpwood to transfer the pulpwood to the charging conveyor, and switch means positioned adjacent said guide means and coupled to said drive means to deactivate the drive means when the guide means is in said displaced position, said drive means comprising a ratchet gear with a pawl, and said switch means comprising s switch actuated by said guide means in the displaced position thereof and an electromagnet coupled to said switch and pawl to disengage the latter from the ratchet gear when the switch is actuated.
Claim 2
Dependent Claim
149 words
Apparatus for feeding pulpwood to a charging conveyor for the supply of pulpwood to defibre magazines, said apparatus comprising a vibratory table for pulpwood, conveyor means for feeding pulpwood from the table towards the charging conveyor, drive means for said conveyor means, displaceable guide means for receiving pulpwood from the conveyor means and moving to a displaced position under the weight of the pulpwood to transfer the pulpwood to the charging conveyor, and switch means positioned adjacent said guide means and coupled to said drive means to deactivate the drive means when the guide means is in said displaced position, said drive means comprising a ratchet gear with a pawl, and said switch means comprising s switch actuated by said guide means in the displaced position thereof and an electromagnet coupled to said switch and pawl to disengage the latter from the ratchet gear when the switch is actuated.
Claim 3
Dependent Claim
72 words
Apparatus as claimed in claim 1 comprising a drum with grips for the pulpwood placed between said table and said conveyor means, drive means for said drum, a second displaceable guide means between said drum and said conveyor means for transferring pulpwood therebetween, and second switch means adjacent the second guide means and coupled to the drive means for the drum to deactivate the latter when the second guide means is displaced.
