Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
In an automatic grain sampling device including a paddle wheel in a housing and a continuously moving conveyor belt advancing a continuous stream of grain, the paddle wheel being so positioned relative to the grain stream such that the paddles engage the grain stream to drive or rotate the wheel, the improvement comprising a receptacle carried by the wheel operative to retrieve periodically and automatically a sample of grain from said moving stream; hopper means cooperating with the receptacle and into which the receptacle automatically dumps the grain, and means for controlling the size of sample dumped cooperating with the receptacle and attached to said housing.
Claim 2
Dependent Claim
106 words
In an automatic grain sampling device including a paddle wheel in a housing and a continuously moving conveyor belt advancing a continuous stream of grain, the paddle wheel being so positioned relative to the grain stream such that the paddles engage the grain stream to drive or rotate the wheel, the improvement comprising a receptacle carried by the wheel operative to retrieve periodically and automatically a sample of grain from said moving stream; hopper means cooperating with the receptacle and into which the receptacle automatically dumps the grain, and means for controlling the size of sample dumped cooperating with the receptacle and attached to said housing.
Claim 3
Dependent Claim
10 words
The device of claim 1 wherein said receptacle is cup-like.
Claim 4
Dependent Claim
10 words
The device of claim 1 wherein said receptacle is box-like.
Claim 5
Dependent Claim
38 words
The device of claim 1 wherein the control means comprises a slide having an aperture, said slide being movable relative to said hopper means effective to change the size of the aperture to effectively control the sample size.
Claim 6
Dependent Claim
25 words
The device of claim 4 in which the control means includes an overflow spout operative to direct excessive grain sample back to the grain stream.
Claim 7
Dependent Claim
29 words
The device of claim 5 wherein said hopper means comprises a conduit in communication with said aperture, and a sample container attached to and in communication with said conduit.
Claim 8
Dependent Claim
34 words
The device of claim 4 additionally including a proportioner means cooperating with said control means to direct the sized sample to said hopper means and to direct excess grain back to the grain stream.
Claim 9
Dependent Claim
65 words
In a grain sampler of the type utilizing a paddle wheel including a grain receptacle, all driven by an advancing grain stream, the improvement comprising a proportioner means operative to receive the sample and to size the sample, and control means cooperating with the proportioner means to direct the sized sample to a sample hopper and to direct excess grain back to the grain stream.
Claim 10
Dependent Claim
65 words
In a grain sampler of the type utilizing a paddle wheel including a grain receptacle, all driven by an advancing grain stream, the improvement comprising a proportioner means operative to receive the sample and to size the sample, and control means cooperating with the proportioner means to direct the sized sample to a sample hopper and to direct excess grain back to the grain stream.
Claim 11
Dependent Claim
26 words
The device of claim 8 wherein said proportioner means comprising an adjustable baffle means to retard the flow of excess grain back to the grain stream.
Claim 12
Dependent Claim
24 words
The device of claim 9 wherein said baffle means comprises a plurality of cooperating webs movable from one fixed position to another fixed position.
Claim 13
Dependent Claim
66 words
The device of claim 10 wherein said plurality of cooperating webs comprises a pair of webs connecting and pivoting about a common point, a third web pivoting at another point and cooperating with one of said pair of webs, the other of said pair of webs is operative to engage said grain to retard the flow of same to encourage the sampling of the correct amount.
