Abstract
Abstract A fill pipe assembly adapted to be connected to a silo and extend from the top thereof to the lower portion for connection to a blower or the like by which the silo is filled with silage, etc. The upper end of the fill pipe has a laterally extending discharge structure and the invention primarily comprises the provision of suitable pivots and brackets which are axially aligned and intermediately spaced between the upper and lower ends of the conduit, whereby the conduit may be oscillated to move the lateral discharge extension in a to and fro pattern to move evenly distribute the discharged material in the silo than under circumstances where no pivoting of the fill pipe is possible.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
A fill pipe assembly adapted to be connected to a silo adjacent the exterior wall thereof and comprising in combination, an elongated tubular conduit having a laterally extending discharge end structure directed toward the axis of the top of said silo, upper pivot means adapted to be fixedly connected to the upper portion of a silo adjacent the wall thereof, uppermost bracket means connected to said pivot means and extending laterally therefrom to the upper end of said conduit and connected thereto, lowermost bracket means adapted to be fixedly connected at one end to said silo wall adjacent the lower end thereof and the opposite end having a bearing surrounding the lower portion of said conduit to support the same in substantially spaced relation to said silo wall, and additional bracket means spaced intermediately between said uppermost and lowermost bracket means and connectable at one end to said silo wall and the other end being fixedly connected to said conduit, said additional bracket means being articulated and having pivot means intermediate the ends thereof in axial alignment with the axes of said upper pivot means and the bearing of said lowermost bracket, whereby said conduit may be oscillated about said aligned axes to effect arcuate oscillation of the discharge end structure of said conduit to produce to and fro discharge of silage therefrom.
Claim 2
Dependent Claim
223 words
A fill pipe assembly adapted to be connected to a silo adjacent the exterior wall thereof and comprising in combination, an elongated tubular conduit having a laterally extending discharge end structure directed toward the axis of the top of said silo, upper pivot means adapted to be fixedly connected to the upper portion of a silo adjacent the wall thereof, uppermost bracket means connected to said pivot means and extending laterally therefrom to the upper end of said conduit and connected thereto, lowermost bracket means adapted to be fixedly connected at one end to said silo wall adjacent the lower end thereof and the opposite end having a bearing surrounding the lower portion of said conduit to support the same in substantially spaced relation to said silo wall, and additional bracket means spaced intermediately between said uppermost and lowermost bracket means and connectable at one end to said silo wall and the other end being fixedly connected to said conduit, said additional bracket means being articulated and having pivot means intermediate the ends thereof in axial alignment with the axes of said upper pivot means and the bearing of said lowermost bracket, whereby said conduit may be oscillated about said aligned axes to effect arcuate oscillation of the discharge end structure of said conduit to produce to and fro discharge of silage therefrom.
Claim 3
Dependent Claim
68 words
The fill Pipe assembly according to claim 1 in which said additional bracket means is provided with base means at one end attachable to the sidewall of the silo, clamping means at the outer end of said bracket means connected to said conduit, and arm means extending between said base means and clamping means and comprising two sections connected together by a pivot having a substantially vertical axis.
Claim 4
Dependent Claim
21 words
The fill pipe assembly according to claim 2 in which one of said sections of said arm means is longitudinally adjustable.
Claim 5
Dependent Claim
29 words
The pipe fill assembly according to claim 3 in which said longitudinally adjustable section is provided with telescoping portions and means to secure the same in longitudinally adjusted position.
Claim 6
Dependent Claim
33 words
The pipe fill assembly according to claim 2 in which the clamping means at the other end of said additional bracket means comprises a clamping band surrounding the conduit and tightly clamped thereto.
Claim 7
Dependent Claim
53 words
The fill pipe assembly according to claim 1 in which the lowermost bracket means is provided at one end with a base attachable fixedly to the exterior surface of a silo wall and the opposite end thereof having a ring bearing supported thereby, said ring bearing being coaxial with and surrounding said conduit.
Claim 8
Dependent Claim
40 words
The fill pipe assembly according to claim 6 in which said ring bearing is composite and comprises separable portions of a circular band, and an annular channel rotatably supported within said circular band, said channel being clamped to said conduit.
Claim 9
Dependent Claim
83 words
The fill pipe assembly according to claim 7 in which said annular channel comprises two similar sections having laterally extending annular flanges and one of said flanges being provided with ears extending perpendicularly to the plane of the flanges adjacent the ends of said sections, the ears of said sections being adapted to abut each other along planes extending perpendicularly to the axis of said conduit, and connecting means extending through said ears to securely clamp said annular channel sections to said conduit.
Claim 10
Dependent Claim
74 words
The fill pipe assembly according to claim 6 further including actuating means connected to and projecting radially from the lower end portion of said conduit and operable to effect oscillation of the conduit about the axes of the aligned pivot means and bearing interconnected to said conduit and thereby permit axial oscillation thereof about a straight line extending vertically between the upper and lower portions of a silo when said conduit is connected thereto.
Claim 11
Dependent Claim
56 words
The fill pipe assembly according to claim 9 in which said actuating means comprises an articulated band which surrounds and is clamped to the lower portion of said conduit, said band comprising a plurality of similar arcuate sections and one of said sections having a lateral projection extending therefrom for the application of oscillating force thereto.
