Triple roller entry guide
First Claim
1. A roller entry guide to guide material along a longitudinal axis, said guide comprising:
- a hollow housing having multiple pivot means incorporated therein for pivotally mounting at least three roller assemblies thereon at equally spaced angles about said longitudinal axis,said pivot means being located in a common plane transverse to said longitudinal axis, a roller assembly mounted on each pivot means comprising a lever having a roller mounted in a first end of said lever and an adjustment means mounted at the second end of said lever,mounting means associated with each lever for mounting each lever on each pivot means of said housing at a point intermediate said first and second ends,motion inducing means mounted on said housing for forcibly causing said roller assemblies to pivot in concert in a radial direction to move said rollers inwardly toward said longitudinal axis of said housing.

Abstract
An entry guide device comprising a funnel shaped inlet member in close proximity to three adjustable rollers mounted at 120° around the axis of work moving through the entry guide device. The adjustable rollers are actuated to move in concert so as to be able to accommodate a work product of difference diameters, whilst preserving the concentricity of the three rollers. The funnel shaped inlet member is replaceable to accommodate for wear and provision is made to calibrate the position of the three movable rollers with a calibration device which may be conveniently inserted into the device to check and calibrate the three rollers for concentricity. This entry guide device is ideally suited for guiding a work produce having circular, triangular or hexagonal cross-sections.

7. A roller entry guide for a guiding a steel rod along a longitudinal axis comprising:
-
a hollow metallic housing having a funnel shaped cavity extending therethrough along said axis, said funnel shaped cavity being substantially co-axial with said longitudinal axis so as to define an entrance aperture and a substantially smaller exit aperture, said housing having threaded boss means surrounding said entrance aperture, cone means threaded on said threaded boss means and being rotatable to move axially along said longitudinal axis, three pivoting lever members each having a roller mounted in one end thereof, mounted at 120°
spaced intervals about said longitudinal axis on said housing so that the three rollers carried by said levers have a common confluence at a point adjacent to and spaced from said exit aperture,each lever also having a set screw adjusting means at each end opposite said roller for engagement with said cone means, to move said rollers inwardly toward said longitudinal axis. - View Dependent Claims (8, 9, 10)
