Abstract
Abstract A machine for continuously conveying slabs of meat, such as bacon, to a revolving blade and slicing same into accurate, weight controlled groupings, preferably by control of the conveying system. The machine has a plurality of longitudinally spaced, generally transversely extending rollers and a plurality of finger means mounted on the front roller that is adjacent to the blade, but rearward of the front roller, to apply downward and rearward forces to the conveyor supported slab to positively control the slab travel to, and particularly adjacent, the blade.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A slicing machine comprising: (a) a support frame: (b) a slicer blade mounted for rotation on said frame; (c) an anvil mounted on said frame adjacent said blade; (d) an endless conveyor mounted on said frame for feeding a slab of material forwardly over said anvil into the path of rotation of said blade; (e) a plurality of longitudinally spaced, generally transversely extending rollers pivotally mounted on said frame above said conveyor and generally coextensive with said conveyor for applying downward and rearward forces to the slab; (f) a plurality of finger means slidably mounted on the front roller adjacent said blade, but rearwardly of said front roller for movement therewith, said finger means extending forwardly of said front roller toward said blade to contact the slab; and (g) means for biasing said rollers and therefore said finger means toward the slab to control slab travel to said knife.
Claim 2
Dependent Claim
149 words
A slicing machine comprising: (a) a support frame: (b) a slicer blade mounted for rotation on said frame; (c) an anvil mounted on said frame adjacent said blade; (d) an endless conveyor mounted on said frame for feeding a slab of material forwardly over said anvil into the path of rotation of said blade; (e) a plurality of longitudinally spaced, generally transversely extending rollers pivotally mounted on said frame above said conveyor and generally coextensive with said conveyor for applying downward and rearward forces to the slab; (f) a plurality of finger means slidably mounted on the front roller adjacent said blade, but rearwardly of said front roller for movement therewith, said finger means extending forwardly of said front roller toward said blade to contact the slab; and (g) means for biasing said rollers and therefore said finger means toward the slab to control slab travel to said knife.
Claim 3
Dependent Claim
22 words
The slicing machine of claim 1 further comprising guide means for restricting travel of said finger means to substantially a vertical plane.
Claim 4
Dependent Claim
52 words
The slicing machine of claim 2 in which the pivotal mounting of said first roller comprises a first pair of spaced links and a second pair of rearwardly mounted links, each pair of links being connected by a pair of shafts and said plurality of finger means are mounted on said shafts.
Claim 5
Dependent Claim
29 words
The slicing machine of claim 3 in which each of said plurality of finger means are aligned generally transversely of said conveyor and are individually biased toward the slab.
Claim 6
Dependent Claim
28 words
The slicing machine of claim 4 in which said first roller comprises a plurality of spaced roller portions and each of said finger means extends between said portions.
Claim 7
Dependent Claim
50 words
The slicing machine of claim 5 further comprising a side guide means and in which each of said rollers is tapered and has its smallest diameter adjacent said side guide means and said conveyor is mounted parallel to said rollers for movement of the slab toward said side guide means.
Claim 8
Dependent Claim
23 words
The slicing machine of claim 6 in which said means for biasing said rollers is a single acting air cylinder for each roller.
