Abstract
Abstract A feeding device for feeding goods or materials of the kind having several layers and/or having a tendency to separate into layers into a processing machine in a direction generally parallel with those layers, for example, for feeding pulp bales into a disintegrating machine comprising a roller conveyor for displaceably supporting the goods and a driving device to engage the goods and displace those goods along the roller conveyor in order to force the goods into the processing machine wherein the driving device includes a pusher drivable along the roller conveyor which pusher is adapted to engage with substantially the entire rear or trailing surface of the goods for forcing the goods into the processing machine while substantially uniformly acting on all of the layers of the goods. The pusher is mounted on a carriage which is connected to a drive chain by means of a pin. As the portion of the chain engaged by the pin passes about the sprocket at the end of the conveying run, the teeth of the sprocket push the pin out of the chain thereby disengaging the carriage drive.

Claim 1
Independent Claim
173 words
Apparatus for feeding goods of the type having a tendency to separate into layers into a processing machine in a direction generally parallel with the layers comprising: a roller conveyor for movably supporting the goods, a pair of channel beams positioned on each side of said roller conveyor, a carriage positioned between each pair of said channel beams, each said carriage having a pair of rollers on each side thereof, said pairs of rollers being disposed respectively within said channels so as to guide said carriages, a gate adapted to engage the goods supported on said roller conveyor, a pair of vertical rods connected respectively to said carriages and positioned to engage said gate, a pair of chains engaged by driven sprockets, said chains having link shafts separated by spaces, and vertically movable pin means received in each said carriage, said pin means having lower ends in engagement respectively with said chains in the spaces between said link shafts and adapted to be released from said chains by the teeth of said sprockets.

Claim 3
Dependent Claim
124 words
In a machine for pressing goods into a processing machine, the combination of: a conveyor for the goods, channel beams parallel to said conveyor, a carriage having rollers guided by and rolling in said channel beams, pusher means connected to said carriage and extending over said conveyor to push the goods forward, a chain running over at least one driven sprocket, said chain having a plurality of link shafts and spaces therebetween, movable pin means received in said carriage and having a lower end for releasably engaging said chain by being inserted into the spaces of said chain, said sprocket including means in the form of teeth for engaging said pin means to thereby release the same from said chain and disengage said carriage.
Claim 4
Dependent Claim
124 words
In a machine for pressing goods into a processing machine, the combination of: a conveyor for the goods, channel beams parallel to said conveyor, a carriage having rollers guided by and rolling in said channel beams, pusher means connected to said carriage and extending over said conveyor to push the goods forward, a chain running over at least one driven sprocket, said chain having a plurality of link shafts and spaces therebetween, movable pin means received in said carriage and having a lower end for releasably engaging said chain by being inserted into the spaces of said chain, said sprocket including means in the form of teeth for engaging said pin means to thereby release the same from said chain and disengage said carriage.
Claim 5
Dependent Claim
175 words
A feeding device for feeding goods of the kind having a tendency to separate into layers into a processing machine in a direction generally parallel with the layers comprising: a roller conveyor for movably supporting the goods, pusher means for engaging generally the entire rear surface of the goods for feeding the goods into the processing machine, a drive chain, carriage means for guiding said pusher means along said roller conveyor, said carriage means being guided in at least one track extending parallel with said roller conveyor, said carriage including engagement means for engaging said drive chain in order to establish a driving connection between said carriage and said drive chain, said pusher means being connected to and supported by said carriage, said chain extending over a sprocket at the end of said roller conveyor, said engagement means being adapted to be released from said chain by the teeth of said sprocket at the end of said roller conveyor initiating the return of said carriage means and said pusher means to the feeding start position.
