Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
An in-line vibratory feeder comprising, in combination, an action mass having track-mounting means thereon; a reaction mass; a coil; an armature for actuation by the coil; a base member having spaced spring-mounting means thereon; a pair of action mass elongate springs secured to the base and action mass; a pair of reaction mass elongate springs secured to the base and the reaction mass; said reaction mass having a coil yoke member relief portion to provide coil clearance and secured at its ends to the reaction mass springs; means for mounting the armature to one of said masses; and a pair of coil-mounting plates having securing means thereon to flankingly engage the coil and secure the same to the plates, and second securing means to secure the plates to the other said mass, one of said securing means being adjustable thereby permitting an adjustment of the gap between the coil and the armature.
Claim 2
Dependent Claim
152 words
An in-line vibratory feeder comprising, in combination, an action mass having track-mounting means thereon; a reaction mass; a coil; an armature for actuation by the coil; a base member having spaced spring-mounting means thereon; a pair of action mass elongate springs secured to the base and action mass; a pair of reaction mass elongate springs secured to the base and the reaction mass; said reaction mass having a coil yoke member relief portion to provide coil clearance and secured at its ends to the reaction mass springs; means for mounting the armature to one of said masses; and a pair of coil-mounting plates having securing means thereon to flankingly engage the coil and secure the same to the plates, and second securing means to secure the plates to the other said mass, one of said securing means being adjustable thereby permitting an adjustment of the gap between the coil and the armature.
Claim 3
Dependent Claim
27 words
In the in-line vibratory feeder of claim 1, wherein said armature is mounted to said action mass, and said coil-mounting plates are secured to said reaction mass.
Claim 4
Dependent Claim
27 words
In the in-line vibratory feeder of claim 1, wherein said armature is mounted to said reaction mass and said coil-mounting plates are secured to said action mass.
Claim 5
Dependent Claim
24 words
In the in-line feeder of claim 1, the action and reaction mass springs being parallel pairs, and each pair having equal effective unsupported lengths.
Claim 6
Dependent Claim
26 words
In the in-line feeder of claim 4, said armature and coil being mounted with the coil magnetic axis perpendicular to the action and reaction mass springs.
Claim 7
Dependent Claim
36 words
In the in-line feeder of claim 5, an L-shaped armature secured beneath the action mass track base, one leg of the L secured to the track base, the other leg perpendicular to the coil magnetic axis.
Claim 8
Dependent Claim
12 words
In the in-line feeder of claim 1, equal action and reaction masses.
Claim 9
Dependent Claim
26 words
In the in-line feeder of claim 1, means defining a porthole in the sideplates thereby permitting visual observation of the gap between the coil and armature.
Claim 10
Dependent Claim
121 words
In the in-line feeder of claim 1, means defining slots in the sideplate opposite the coil yoke, means for securing the sideplates and coil to the yoke whereby the coil gap may be adjusted by moving the sideplates and coil along the axis of the slots, the action and reaction springs being parallel pairs, each pair having equal effective lengths, said armature and coil being mounted with the coil magnetic axis perpendicular to the action and reaction mass springs, an L-shaped armature secured beneath the action mass track base, one leg of the L secured to the track base, the other leg perpendicular to the coil magnetic axis, the whole proportioned to equalize the mass of the action and reaction masses.
