Abstract
Abstract Continuous automatic feeding apparatus for bulk material is provided. The device has a vibratory feeder for moving the material to be fed, the feeder having a centrally disposed narrow spoon extending therefrom which provides a relatively small rate of material feed. A pair of hoppers are located under the composite feeder, and the material supplied to each controlled by a pair of displaceable deflectors. Each deflector has three positions: a first position in which the deflector prevents any flow into its associated hopper and deflects the flow into the other hopper; a second position in which the flow from the feeder is deflected to the other hopper but the flow from the spoon is permitted to enter its associated hopper; and a third position in which the flow from both the vibratory feeder and the spoon enters the associated hopper. Each hopper has a weigh cell and control apparatus associated therewith to operate the deflectors and empty the hoppers when a predetermined weight has been attained.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
Automatic continuous feeding apparatus for fluent material comprising; (a) first and second hopper means; (b) means for determining the weight of said first and second hopper means; (c) means for discharging said first and second hopper means when said hopper first and second hopper means reach a predetermined weight; (d) feeder means discharging said material into said hopper means, said feeder means coincidently discharging said material at first and second discharge rates; (e) first and second deflector means associated with said first and second hopper means, each of said deflector means having first, second and third positions, at said first position said deflector means preventing any discharge of said feeder means into said associated hopper, but deflecting said discharge into the other of said hoppers; at said second position said deflector permitting said material discharging at said first discharge rate to enter its associated hopper and deflecting said material flowing at said second discharge rate into the other of said hoppers; at said third position said deflectors permitting all of said material to be discharged into their associated hoppers; and (f) means for displacing said first and second deflector means into said first, second and third positions.

Claim 3
Dependent Claim
48 words
Apparatus as claimed in claim 1, wherein said first and second hopper means include at least one moveable wall being displaceable from a first position in which said material is held in place to a second position in which said material is displaced by gravity from said hopper.
Claim 4
Dependent Claim
38 words
Apparatus as claimed in claim 2, wherein said first and second hopper means further include at least two-fixed parallel walls, an axis normal to said to said parallel walls, said moveable wall being rotatably mounted about said axis.
Claim 5
Dependent Claim
51 words
Apparatus as claimed in claim 3, said first and second hopper means further including four radially extending moveable walls, each of said moveable walls being located at a 90° angle with respect to each other and latter means engaging one of said radially extending walls for holding said walls in place.
Claim 6
Dependent Claim
42 words
Apparatus as claimed in claim 1, wherein said feeder means comprise a vibratory feeder tray, said tray including a forward edge, said tray being reciprocated along its longitudinal axis to displace said material over said forward edge at said first discharge rate.
Claim 7
Dependent Claim
36 words
Apparatus as claimed in claim 5, wherein said vibratory feeder tray further includes a vibratory feeder spoon extending from said forward edge of said tray, said spoon discharging said material at a said second discharge rate.
Claim 8
Dependent Claim
63 words
Apparatus as claimed in claim 6, wherein said deflector means are displaceable parallel to the longitudinal axis of said tray, said deflector means having said first position extending beyond the said vibratory feeder spoon, said second position between said vibratory feeder spoon and said forward edge of said vibratory feeder and said third position within said forward edge of said vibratory feeder spoon.
Claim 9
Dependent Claim
63 words
Apparatus as claimed in claim 1, wherein said feeder means are located above said hopper means and said material flows into said hopper means by means of gravity, said deflector means being located between said feeder means and said hopper means, said deflector means being displaceable in and out of said flow of said material between said feeder means and said hopper means.
Claim 10
Dependent Claim
127 words
In combination material supplying means including feeder means having a discharge area and spoon means extending beyond said feeder discharge area, first and second adjacent hoppers each disposed beneath a portion of said feeder means and a portion of said spoon means, first and second deflectors means respectively disposed between said first and second hoppers and said material supplying means for selectively deflecting material supplied by said material supplying means to the other of said hoppers and means for selectively disposing each said deflector means in a first position and a third position for full communication and full isolation between said material supplying means and said hopper associated with said deflector means, and a second, intermediate position permitting communication between said spoon means and said associated hopper.
Claim 11
Dependent Claim
127 words
In combination material supplying means including feeder means having a discharge area and spoon means extending beyond said feeder discharge area, first and second adjacent hoppers each disposed beneath a portion of said feeder means and a portion of said spoon means, first and second deflectors means respectively disposed between said first and second hoppers and said material supplying means for selectively deflecting material supplied by said material supplying means to the other of said hoppers and means for selectively disposing each said deflector means in a first position and a third position for full communication and full isolation between said material supplying means and said hopper associated with said deflector means, and a second, intermediate position permitting communication between said spoon means and said associated hopper.
