Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
234 words
A device for evenly distributing the liquid contents of sealed packets containing liquid saturated towels or the like comprising a first endless conveyor, a plurality of flat support block members fixed to said conveyor, anti-friction means disposed in the path of said support blocks for aligning the upper surfaces of the blocks traversing said means in a predetermined horizontal plane, a second endless conveyor having a lower flight in parallel spaced relation to the upper flight of said conveyor, a plurality of compression blocks carried by said second conveyor, drive means for moving said conveyors in a converging path toward said anti-friction means, said conveyors being advanced in timed relation whereby the support and compression blocks are in registry at said anti-friction means, and adjustment means yieldably urging said compression blocks toward said anti-friction means with a selected force, said adjustment means including a rotatable cross shaft disposed in parallel spaced relation to said anti-friction means, said cross shaft including an eccentric member shiftable toward and away from said anti-friction means responsive to rotation of said cross shaft, roller means positioned to engage said compression blocks as the same traverse said anti-friction means and spring means compressed between said rollers and said eccentric member, the degree of compression of said spring means being varied responsive to the rotated position of said cross shaft, said compression blocks being tiltably mounted relative to said antifriction means.
Claim 2
Independent Claim
234 words
A device for evenly distributing the liquid contents of sealed packets containing liquid saturated towels or the like comprising a first endless conveyor, a plurality of flat support block members fixed to said conveyor, anti-friction means disposed in the path of said support blocks for aligning the upper surfaces of the blocks traversing said means in a predetermined horizontal plane, a second endless conveyor having a lower flight in parallel spaced relation to the upper flight of said conveyor, a plurality of compression blocks carried by said second conveyor, drive means for moving said conveyors in a converging path toward said anti-friction means, said conveyors being advanced in timed relation whereby the support and compression blocks are in registry at said anti-friction means, and adjustment means yieldably urging said compression blocks toward said anti-friction means with a selected force, said adjustment means including a rotatable cross shaft disposed in parallel spaced relation to said anti-friction means, said cross shaft including an eccentric member shiftable toward and away from said anti-friction means responsive to rotation of said cross shaft, roller means positioned to engage said compression blocks as the same traverse said anti-friction means and spring means compressed between said rollers and said eccentric member, the degree of compression of said spring means being varied responsive to the rotated position of said cross shaft, said compression blocks being tiltably mounted relative to said antifriction means.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 and including an adjustment lever mounted to said cross shaft, and indexing means operably connected to said adjustment lever for securing said indexing means in a selected one of a plurality of indexed positions.
