Abstract
Abstract Coal, and the like, contained in a truck is sampled by initially removing a core sample from the load, crushing the sample, dividing out an unwanted portion of the crushed sample, and returning the unwanted portion back to the load while the sample portion is delivered to a predetermined receptacle associated with a vender of the coal or other material forming the load. An auger mounted for reciprocation in a substantially vertical path and having a cutting head at the lower end is provided for cutting through the lumps of coal in order to obtain a representative sample.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
173 words
A system for sampling a load of bulk material disposed on a stationary carrier, comprising, in combination: (A) a supporting frame; (B) core removal means vertically, reciprocally mounted on the frame for gathering samples from a bulk material disposed below the core removal means; and (C) processing means mounted on the frame for receiving samples from the core removal means and processing the samples for analysis of the quality of the material constituting the load; wherein the core removal means includes, in combination: (1) sample tube means mounted on the frame for reciprocating movement along a substantially vertical path of travel toward and away from a load of bulk material to be sampled; and (2) conveyor means mounted on the frame for reciprocating movement in a substantially horizontal plane between a position extending from beneath the sample tube to the processing means, and a position to one side of the vertical path of travel of the sample tube so as to permit the sample tube to travel downwardly toward the load being sampled.
Claim 2
Independent Claim
173 words
A system for sampling a load of bulk material disposed on a stationary carrier, comprising, in combination: (A) a supporting frame; (B) core removal means vertically, reciprocally mounted on the frame for gathering samples from a bulk material disposed below the core removal means; and (C) processing means mounted on the frame for receiving samples from the core removal means and processing the samples for analysis of the quality of the material constituting the load; wherein the core removal means includes, in combination: (1) sample tube means mounted on the frame for reciprocating movement along a substantially vertical path of travel toward and away from a load of bulk material to be sampled; and (2) conveyor means mounted on the frame for reciprocating movement in a substantially horizontal plane between a position extending from beneath the sample tube to the processing means, and a position to one side of the vertical path of travel of the sample tube so as to permit the sample tube to travel downwardly toward the load being sampled.
Claim 3
Dependent Claim
67 words
A structure as defined in claim 1, wherein the sample tube means comprises, in combination: (a) a longitudinally extending casing hollow at a lower end thereof and reciprocatively mounted on the frame; (b) an auger rotatably mounted within the casing and extending substantially the entire length of the casing; and (c) a cutting head connected to the auger and disposed in the open end of the casing.
Claim 4
Dependent Claim
61 words
A structure as defined in claim 2, wherein the sample tube means further includes support means comprising a tower mounted on the framework, a linear fluid motor connected to the framework and disposed within the tower, and a sheave assembly connected to the motor and to the casing for moving the casing as a function of the movement of the motor.
Claim 5
Dependent Claim
66 words
A structure as defined in claim 3, wherein the processing means comprises, in combination: (3) crusher means for receiving a sample from the core removal means and crushing the sample; (4) secondary sample means connected to the crusher means for separating out a predetermined portion of the crushed sample; and (5) collector means for receiving the predetermined portion of the sample and retaining same for analysis.
Claim 6
Dependent Claim
95 words
A structure as defined in claim 4, wherein the collector means includes indexing means comprising a container connected to the secondary sampler means for receiving the predetermined portion of crushed sample, which container has an inlet and outlet; a plurality of receptacles disposed in circular arrangement beneath the container, the indexing means including a turntable on which the receptacles are disposed for being rotated in a substantially circular orbit; and conduit means including a plurality of chutes connected to the receptacles and extending toward the container for selectively registering with the outlet of the container.
Claim 7
Dependent Claim
46 words
A structure as defined in claim 5, wherein the processing means further comprises: (6) material return means connected to the secondary sampler means for returning to the load from which the sample was taken the sample less the predetermined portion of the sample retained for analysis.
Claim 8
Dependent Claim
72 words
A structure as defined in claim 6, wherein the material return means includes elevator means connected to the secondary sampler means for receiving the portion of the sample to be returned to the load from which it was taken, and elevating the portion of sample being returned, and a discharge chute arranged connected to the elevator means at an elevated discharge portion thereof for directing the material to the load being sampled.
Claim 9
Dependent Claim
61 words
A structure as defined in claim 2, wherein the sample tube means further includes support means comprising a tower mounted on the framework, a linear fluid motor connected to the framework and disposed within the tower, and a sheave assembly connected to the motor and to the casing for moving the casing as a function of the movement of the motor.
Claim 10
Dependent Claim
66 words
A structure as defined in claim 8, wherein the processing means comprises, in combination: (7) crusher means for receiving a sample from the core removal means and crushing the sample; (8) secondary sample means connected to the crusher means for separating out a predetermined portion of the crushed sample; and (9) collector means for receiving the predetermined portion of the sample and retaining same for analysis.
Claim 11
Dependent Claim
95 words
A structure as defined in claim 5, wherein the collector means includes indexing means comprising a container connected to the secondary sampler means for receiving the predetermined portion of crushed sample, which container has an inlet and outlet; a plurality of receptacle disposed in circular arrangement beneath the container, the indexing means including a turntable on which the receptacles are disposed for being rotated in a substantially circular orbit; and conduit means including a plurality of chutes connected to the receptacles and extending toward the container for selectively registering with the outlet of the container.
Claim 12
Dependent Claim
47 words
A structure as defined in claim 10, wherein the processing means further comprises: (10) material and return means connected to the secondary sampler means for returning to the load from which the sample was taken the sample less the predetermined portion of the sample retained for analysis.
Claim 13
Dependent Claim
162 words
A sample tube for obtaining a substantially vertical core sample of a stationary load which may include large pieces of hard material, comprising, in combination: (a) a longitudinally extending casing open at a lower end thereof and mounted for reciprocal movement along a substantially vertical path; (b) an auger rotatably mounted within the casing and extending substantially entirely the extent of the casing; and (c) a cutting head connected to the auger and disposed in the open end of the casing for cutting through the hard material prior to carrying of the material into the casing by rotation of the auger to which the cutting head is affixed; wherein the sample tube means further includes support means comprising a tower mounted on the framework, a linear fluid motor connected to the framework and disposed within the tower, and a sheave assembly connected to the motor and to the casing for moving the casing as a function of the movement of the motor.
