Abstract

Abstract A storage and dispensing tank for granular material including upper and lower portions. The lower portion of the tank includes a first pair of opposite side wall portions which are downwardly convergent to a central elongated bottom wall structure extending between and along the lower edges of the side wall portions. The lower portion also includes a second pair of opposite front and rear walls extending between and connecting the side wall portions. The front and rear walls are only slightly downwardly convergent and the bottom wall structure includes a plurality of longitudinally spaced valved gravity discharge openings. Also, an upright partition extends between and is secured to the side wall portions between each pair of adjacent gravity discharge openings and the lower end of each partition includes inclined baffles extending to the adjacent ends of the adjacent discharge openings.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 284 words
A storage and dispensing tank for granular material including upper and lower portions, said lower portion including a first pair of downwardly convergent opposite side wall portions spaced apart at their lower ends, an elongated bottom wall structure extending between and along the lower portions of said side wall portions, said bottom wall structure including a plurality of longitudinally spaced gravity discharge outlet openings, valve means operatively associated with said outlet openings for selectively opening and closing the latter, said lower portion including a second pair of opposite front and rear walls extending between said side wall portions and to whose lower ends the opposite ends of said bottom wall structure are secured, said upper portion including substantially vertical opposite side and front and rear panels projecting upwardly from the upper marginal edges of said lower portion, four horizontally spaced apart standards, the lower and upper corner portions of said upper and lower tank portions, respectively, being supported between and from the upper end portions of said standards with said lower portion in elevated position relative to the lower ends of said standards, a generally inverted V-shaped brace secured between each pair of adjacent standards and to said tank, the apices of said braces being attached to the horizontal midportions of the lower marginal edge portions of said opposite side and front and rear panels and the free ends of the legs of said braces being secured to the corresponding standards, and a horizontal elongated brace member extending and secured between adjacent standards of said tank at an elevation at least substantially coinciding with the areas of securement of the free ends of the legs of the corresponding inverted V-shaped brace with the standards.
Claim 2
Dependent Claim 284 words
A storage and dispensing tank for granular material including upper and lower portions, said lower portion including a first pair of downwardly convergent opposite side wall portions spaced apart at their lower ends, an elongated bottom wall structure extending between and along the lower portions of said side wall portions, said bottom wall structure including a plurality of longitudinally spaced gravity discharge outlet openings, valve means operatively associated with said outlet openings for selectively opening and closing the latter, said lower portion including a second pair of opposite front and rear walls extending between said side wall portions and to whose lower ends the opposite ends of said bottom wall structure are secured, said upper portion including substantially vertical opposite side and front and rear panels projecting upwardly from the upper marginal edges of said lower portion, four horizontally spaced apart standards, the lower and upper corner portions of said upper and lower tank portions, respectively, being supported between and from the upper end portions of said standards with said lower portion in elevated position relative to the lower ends of said standards, a generally inverted V-shaped brace secured between each pair of adjacent standards and to said tank, the apices of said braces being attached to the horizontal midportions of the lower marginal edge portions of said opposite side and front and rear panels and the free ends of the legs of said braces being secured to the corresponding standards, and a horizontal elongated brace member extending and secured between adjacent standards of said tank at an elevation at least substantially coinciding with the areas of securement of the free ends of the legs of the corresponding inverted V-shaped brace with the standards.
Claim 3
Dependent Claim 88 words
The combination of claim 1 wherein said outlet openings are defined by depending outlet neck portions whose lower ends are defined by lower edge portions disposed in and conforming to an upwardly opening partial cylindrical path, said valve means comprising partial cylindrical gate members oscillatably supported from said outlet neck portions for swinging about their axes of curvature and against whose upper surfaces said lower edge portions conform and seal when said gate members are disposed in vertical registry with the lower ends of said outlet neck portions.
Claim 4
Dependent Claim 24 words
The combination of claim 2 including means connecting said gate members together for equal and simultaneous swinging movement relative to said outlet neck portions.
Claim 5
Dependent Claim 29 words
The combination of claim 1 wherein said lower portion includes a plurality of upstanding partitions secured between said opposite side wall portions between pairs of adjacent discharge outlet openings.
Claim 6
Dependent Claim 36 words
The combination of claim 4 wherein the Lower ends of said partitions include inverted V-shaped baffle means extending downwardly and outwardly from the lower marginal edge portions of said partitions toward the adjacent discharge outlet openings.
