Abstract
Abstract A vibratory evacuator has a base with coil springs on which a vibratory element is mounted so that its upper surface is arranged below an outlet for material to be evacuated. The vibratory element includes a motor mounted beneath the upper surface and having a vertical shaft turning an upper eccentric above the motor and a lower eccentric below the motor. The upper eccentric impresses an orbital and generally horizontal vibration on the element, and the lower eccentric impresses successive tilting motions on the element. At least one discharge passageway leads from the upper surface radially outward from the region of the motor for evacuating the material that is fluidized by the vibration motion.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
232 words
A vibratory evacuator comprising: a. a fixed storage chamber for holding a large quantity of nonfree-flowing material; b. said chamber having a bottom outlet for said material; c. a base supported under said quantity of material; d. coil springs mounted on said base; e. a vibratory element mounted on said springs; f. said vibratory element having an upper surface; g. a vertically oriented, rotatable shaft mounted on said vibratory element beneath said upper surface; h. an upper eccentric secured to an upper region oF said shaft to impress an orbital and generally horizontal vibration on said upper surface; i. a lower eccentric secured to a lower region of said shaft to impress tilting vibrations on said upper surface; j. said upper surface being arranged at the bottom of said quantity of material in substantial registry with said outlet to vibrationally evacuate said material from said chamber; k. a discharge region for said material moving from said upper surface, said discharge region being radially outward from the region of said shaft; l. the space in said chamber vertically above the peripheral region of said upper surface being substantially unobstructed so that said tilting vibration of said upper surface is transmitted directly to a substantial depth of said material in said space; and m. means for rotating said shaft to turn said eccentrics simultaneously to drive said upper surface in both of said motions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
16 words
The evacuator of claim 1 wherein said upper surface is generally dome-shaped with a high center.
Claim 4
Dependent Claim
16 words
The evacuator of claim 1 wherein said upper surface is generally conical with a high center.
Claim 5
Dependent Claim
19 words
The evacuator of claim 1 including an agitator extending above said upper surface and moving with said upper surface.
Claim 6
Dependent Claim
20 words
The evacuator of claim 1 including a flexible sleeve connecting said chamber and a peripheral portion of said vibratory element.
Claim 7
Dependent Claim
20 words

Claim 8
Dependent Claim
22 words
The evacuator of claim 1 wherein said discharge region comprises a spout extending outward from the peripheral edge of said upper surface.
Claim 9
Dependent Claim
21 words
The evacuator of claim 7 including a plurality of said discharge spouts angularly spaced around said periphery of said upper surface.
Claim 10
Dependent Claim
18 words
The evacuator of claim 1 wherein at least one of said eccentrics is angularly adjustable on said shaft.
Claim 11
Dependent Claim
28 words
The evacuator of claim 1 including legs supporting said base and said chamber, and a flexible sleeve connecting said chamber and a peripheral portion of said vibratory element.
Claim 12
Dependent Claim
21 words

Claim 13
Independent Claim
143 words
A method of evacuating a non-free-flowing material from a fixed storage chamber having a bottom outlet through which said material does not normally flow, said method comprising: a. arranging a vibratory surface in the region of said outlet so that a substantial and unobstructed depth of said material is not flowing; b. providing an open discharge region for said material passing through said outlet to flow off said vibratory surface; c. moving said vibratory surface simultaneously in two vibrational modes when flow of said material is desired from said chamber through said discharge region; d. one of said vibrational modes comprising an orbital and generally horizontal vibration of said surface; and e. the other of said vibrational modes comprising tilting vibrations of said surface to transmit shear forces directly to said substantial depth of said material above the periphery of said vibratory surface.
