Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
Apparatus for promoting the flow of material from a bin having a bottom opening, said apparatus comprising, a. a concave material-receiving member terminating in a discharge opening and positioned to receive material from the bin, said member having an inlet opening corresponding to the bottom opening of the bin, b. a first inverted conical baffle secured to the materialreceiving member and having a central opening formed therein, the peripheral surface of said baffle being spaced from the inner wall of the material-receiving member, c. a second inverted conical baffle secured to and axially spaced from the said first baffle, said second baffle having a diameter smaller than that of said first baffle and being positioned above the inlet opening of the material recieving member, d. means for vibrating the material-receiving member, and means suspending the material-receiving member from the bin.
Claim 2
Dependent Claim
140 words
Apparatus for promoting the flow of material from a bin having a bottom opening, said apparatus comprising, a. a concave material-receiving member terminating in a discharge opening and positioned to receive material from the bin, said member having an inlet opening corresponding to the bottom opening of the bin, b. a first inverted conical baffle secured to the materialreceiving member and having a central opening formed therein, the peripheral surface of said baffle being spaced from the inner wall of the material-receiving member, c. a second inverted conical baffle secured to and axially spaced from the said first baffle, said second baffle having a diameter smaller than that of said first baffle and being positioned above the inlet opening of the material recieving member, d. means for vibrating the material-receiving member, and means suspending the material-receiving member from the bin.
Claim 3
Dependent Claim
21 words
The invention as recited in claim 1, wherein the said second baffle is secured to the first baffle by spaced struts.
Claim 4
Dependent Claim
22 words
The invention as recited in claim 1, wherein the said second baffle is positioned above the inlet opening of the material-receiving member.
Claim 5
Dependent Claim
27 words
The invention as recited in claim 1, wherein the said second baffle has a diameter larger than that of the central opening in the said first baffle.
Claim 6
Dependent Claim
81 words
Apparatus for promoting the flow of material from a bin having a bottom opening, said apparatus comprising, a. a concave member terminating in a central opening, b. a pair of axially-spaced, inverted conical baffles carried by the concave member, one of the baffles having a central opening formed therein, and the other baffle being of a smaller diameter and supported by the first baffle by means forming passageways communicating with said opening, and c. vibrator means carried by said concave member.
Claim 7
Dependent Claim
81 words
