Roller entry guide
First Claim
1. A roller entry guide to guide material along a longitudinal axis, said guide having a body, a pair of generally parallel roller assemblies moveably mounted on said body, each of the roller assemblies being located on an opposite side of said longitudinal axis to define a passageway for material moving along said axis, each of said roller assemblies including an arm and a roller rotatably mounted on said arm for engagement with material passing through said passageway, adjustment means acting between said roller assemblies and said body to induce relative movement therebetween and guide means comprising co-operating slides including a passageway inclined to said longitudinal axis, said slides acting between said roller assemblies and said body to guide said roller assemblies at an angle toward and away from said longitudinal axis, and inhibit rotation of said arms relative to said body, said slides maintaining said roller assemblies in a predetermined disposition relative to said longitudinal axis upon movement induced by said adjusting means to displace said roller assemblies relative to said longitudinal axis.

Abstract
A roller entry guide comprises a body with a pair of roller assemblies mounted on the body. The spacing between the assemblies is adjustable by a gear mechanism that induces relative longitudinal displacement between the body and the assemblies. Slides acting between the body and the assemblies produces a lateral component of movement to move the assemblies toward or away from each other while maintaining them parallel.
