Abstract
Abstract A linear vibratory feeder is disclosed in which an action mass is positioned above a reaction mass, both of which are secured to a base by means of leaf type springs. Side plates are secured to the upper or action mass to which the coil is attached. The armature is secured to the underneath portion of the reaction mass, and the coil also mounted beneath the reaction mass to render the centers of gravity of the action and reaction masses substantially coincidental. Means are provided to adjust the gap between the armature and coil, and the action mass center of gravity is ideally located slightly below the center of gravity of the reaction mass to accommodate a track which is mounted atop the action mass.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
204 words
In an inline linear vibratory feeder having an action mass for supporting a linear track, a reaction mass for dynamic balance with the action mass, driving means for imparting opposed forces to the action and reaction masses, a base, yieldable means for securing the action and reaction masses to the base with the action mass above the reaction mass, and a pair of side plates secured in parallel flanking relationships to a portion of driving means and one of said masses; the improvement of an organization and proportion of elements to render the centers of gravity of the total action and reaction masses substantially coincident, comprising: driving means beneath said action and reaction masses, means for fixedly securing a portion of the driving means to each side plate for positioning beneath the action and reaction masses, and means for fixedly securing the side plates to the action mass, thereby coupling the mass of the side plates and a portion of the driving means to the action mass with the entire driving means beneath the action and reaction masses to effect a lowering of the action mass center of gravity to a point substantially coincident with the center of the gravity of the reaction mass.
Claim 2
Dependent Claim
204 words
In an inline linear vibratory feeder having an action mass for supporting a linear track, a reaction mass for dynamic balance with the action mass, driving means for imparting opposed forces to the action and reaction masses, a base, yieldable means for securing the action and reaction masses to the base with the action mass above the reaction mass, and a pair of side plates secured in parallel flanking relationships to a portion of driving means and one of said masses; the improvement of an organization and proportion of elements to render the centers of gravity of the total action and reaction masses substantially coincident, comprising: driving means beneath said action and reaction masses, means for fixedly securing a portion of the driving means to each side plate for positioning beneath the action and reaction masses, and means for fixedly securing the side plates to the action mass, thereby coupling the mass of the side plates and a portion of the driving means to the action mass with the entire driving means beneath the action and reaction masses to effect a lowering of the action mass center of gravity to a point substantially coincident with the center of the gravity of the reaction mass.
Claim 3
Dependent Claim
18 words
In the inline feeder of claim 1, means for adjustably securing the side plates to the action mass.
Claim 4
Dependent Claim
34 words
In the inline feeder of claim 1, said driving means comprising an armature secured to the side plates and beneath the reaction mass, and a coil secured to the reaction mass and there beneath.
Claim 5
Dependent Claim
33 words
In the inline feeder of claim 1, said driving means comprising a coil secured to the side plates and beneath the reaction mass, and an armature secured to the reaction mass and therebeneath.
Claim 6
Dependent Claim
44 words
In the inline feeder of claim 3, said means for securing the side plates to the action mass comprising elongate slots whereby the gap between the coil and the armature may be adjusted by shifting the side plate-coil assembly relative to the action mass.
Claim 7
Dependent Claim
44 words
In the inline feeder of claim 4, said means for securing the side plates to the action mass comprising elongate slots whereby the gap between the armature and the coil may be adjusted by shifting the side plate-coil assembly relative to the action mass.
Claim 8
Dependent Claim
34 words
In the inline feeder of claim 3 said reaction mass having a pair of depending opposed members defining a coil clearance area, one of said depending members serving as one support for the armature.
Claim 9
Dependent Claim
34 words
In the inline feeder of claim 4 said reaction mass having a pair of depending opposed members defining a coil clearance area, one of said depending members serving as one support for the coil.
Claim 10
Dependent Claim
44 words
In the inline feeder of claim 1, said reaction mass center of gravity being above the center of gravity of the action mass by an amount to offset the raising of the action mass center of gravity by the addition of a feeder track.
