Abstract
Abstract An apparatus for removing newspapers from a container in a newspaper live storage buffer having an indexing unit for moving the containers individually from the buffer's conveying device to an unloading position. In the unloading position a pneumatically controlled paddle is raised to engage the newspapers within the container and at approximately the same time a gate forming the bottom of the container is unlatched to permit it to swing to an open position. The paddle is then lowered and is effective in guiding the newspapers into an arcuated channel from which they are delivered for further processing downstream of the buffer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
Apparatus for transporting a stack of newspaper signatures from a first position inside a storage container having a pivotally mounted bottom to a second position spaced from said container for forming an imbricated stream, said apparatus comprising: (a) supporting framework; (b) a signature directing arcuate chute configured to receive signatures in a vertical direction and direct them in an arcuate path toward a horizontal path of travel; said chute having an elongated slot formed in one arcuate wall thereof; (c) an elongated extensible support arm pivotally mounted on said frame so that the outer end thereof can be extended into said signature directing chute and moved through the arcuate length thereof; (d) means to extend said extensible support arm into said arcuate chute to receive and change the position of said stack and to withdraw said outer end of said arm after said stack has been moved; and (e) means to pivot said extensible support arm to change the position of said stack and to return said arm to said first position.
