Abstract
Abstract A material handling apparatus for handling silage, for example, and blowing it upwardly into the top of a silo. The apparatus includes a vertically disposed blower having a single rotor which, with the casing of the blower, defines two separate compartments, each of which are fed separately from opposite sides of the blower. The rotor of the blower has paddles for each of the compartments, the paddles for one of the compartments being staggered circumferentially in respect to the paddles in the other compartment. The apparatus also includes novel feeding means for the blower which comprises a pair of whirling horizontal rotors that evenly distribute the material to opposite sides of the blower.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
A material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite sides each of which having a feed inlet therein, and a rotatable central member located in said housing for rotation about a Generally horizontal axis, said central member being located generally centrally between said opposite sides to thereby define with said housing two separate compartments, said member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially staggered with respect to the paddles located in the other compartment, thereby evenly loading said rotatable plate member.
Claim 2
Dependent Claim
117 words
A material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite sides each of which having a feed inlet therein, and a rotatable central member located in said housing for rotation about a Generally horizontal axis, said central member being located generally centrally between said opposite sides to thereby define with said housing two separate compartments, said member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially staggered with respect to the paddles located in the other compartment, thereby evenly loading said rotatable plate member.
Claim 3
Dependent Claim
23 words
The device as defined in claim 1 further characterized in that said housing has feed means for feeding material to each side thereof.
Claim 4
Dependent Claim
66 words
The device as defined in claim 2 further characterized in that said feed means includes a pair of generally horizontal rotors rotatable about generally vertical axes, one of said rotors being provided for each of the said compartments, said rotors being mounted in a feed inlet housing for conveying material to said blower housing compartments, and a central feed inlet for said rotors located generally therebetween.
Claim 5
Dependent Claim
39 words
The apparatus set forth in claim 3 further characterized in that said rotors are located adjacent one another and rotating in opposite directions, the adjacent sides of said rotors moving in a common direction away from said blower housing.
Claim 6
Dependent Claim
169 words
Material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite flat sides each of which having a feed inlet therein, a plate member located in said housing and rotatable about a generally horizontal axis, said plate member being located centrally between said opposite flat sides to thereby define with said housing two separate compartments, said plate member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially spaced with respect to the paddles located in the other compartment; a pair of horizontal rotors rotatable about generally vertical axes, one of said rotors being provided for each of the said compartments, said rotors being mounted in a feed inlet housing, said feed inlet housing being in communication with said compartments and for conducting material thereto, and a central common feed inlet in said feed inlet housing for said rotors.
Claim 7
Dependent Claim
169 words
Material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite flat sides each of which having a feed inlet therein, a plate member located in said housing and rotatable about a generally horizontal axis, said plate member being located centrally between said opposite flat sides to thereby define with said housing two separate compartments, said plate member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially spaced with respect to the paddles located in the other compartment; a pair of horizontal rotors rotatable about generally vertical axes, one of said rotors being provided for each of the said compartments, said rotors being mounted in a feed inlet housing, said feed inlet housing being in communication with said compartments and for conducting material thereto, and a central common feed inlet in said feed inlet housing for said rotors.
Claim 8
Dependent Claim
39 words
The apparatus set forth in claim 5 further characterized in that said rotors are located adjacent one another and rotating in opposite directions, the adjacent sides of said rotors moving in a common direction away from said blower housing.
Claim 9
Dependent Claim
158 words
A material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite sides each of which having a feed inlet therein, and a rotatable plate member located in said housing for rotation about a generally horizontal axis, said plate member being located generally centrally between said opposite sides to thereby define with said housing two separate compartments, said plate member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially staggered with respect to the paddles located in the other compartment, thereby evenly loading said rotatable plate member, a feed inlet housing for conveying material to said blower housing compartments, and a pair of horizontal rotors in said inlet housing and rotatable about generally vertical axes, one of said rotors being provided for each of the said compartments.
Claim 10
Dependent Claim
158 words
A material handling apparatus having a vertically positioned blower housing of generally circular shape which has a generally tangential discharge conduit extending therefrom, said housing having opposite sides each of which having a feed inlet therein, and a rotatable plate member located in said housing for rotation about a generally horizontal axis, said plate member being located generally centrally between said opposite sides to thereby define with said housing two separate compartments, said plate member having paddles secured circumferentially therearound and on opposite sides thereof for conveying material in each of said compartments, said paddles in one compartment being circumferentially staggered with respect to the paddles located in the other compartment, thereby evenly loading said rotatable plate member, a feed inlet housing for conveying material to said blower housing compartments, and a pair of horizontal rotors in said inlet housing and rotatable about generally vertical axes, one of said rotors being provided for each of the said compartments.
