Abstract
Abstract A portable and collapsible hand tool is disclosed wherein successive small samples of suspected contaminated earth soil may be directly deposited in a sampler bottle, following selective penetrations and extractions of the soil. The sampler is characterized by a substantial balanced mass which is vertically disposed above the sampler tool head, the head having in extension thereof a soil probe column which forms a tube of reverse draft, the same being interconnected to an inverted sampler bottle which is retained within the head where it is shock protected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
An earth soil sampler for the probing extraction and containment of multiple samples of soil, comprising: (A) a rigid shaft which is of substantial mass, relative to the overall sampler; (B) an elongated bottle retainer secured to one end of the shaft, said retainer mounting (B 1 ) shock-resistant bottle securing means intermediate ends of the retainer and (B 2 ) a hollow probe in extension of the lower end of the retainer, said probe having interconnection with the retainer interior of the retainer; (C) a removable sampler bottle held in shock-resistant inverted containment by the retainer and in coactive in-feed relationship to the hollow probe.
Claim 2
Dependent Claim
106 words
An earth soil sampler for the probing extraction and containment of multiple samples of soil, comprising: (A) a rigid shaft which is of substantial mass, relative to the overall sampler; (B) an elongated bottle retainer secured to one end of the shaft, said retainer mounting (B 1 ) shock-resistant bottle securing means intermediate ends of the retainer and (B 2 ) a hollow probe in extension of the lower end of the retainer, said probe having interconnection with the retainer interior of the retainer; (C) a removable sampler bottle held in shock-resistant inverted containment by the retainer and in coactive in-feed relationship to the hollow probe.
Claim 3
Dependent Claim
68 words
The earth soil sampler according to claim 1 wherein the bottle securing means comprises an expansible collar secured inside the top of the retainer to engage by compression the bottom portion of the inverted bottle and a pad with circular projection mounted to the bottom interior of the retainer to engage the bottle mouth and throat interior, thus aligning the bottle in sealed relationship to the hollow probe.
Claim 4
Dependent Claim
34 words
The earth soil sampler according to claim 2, wherein the hollow probe defines an interior column of reverse draft, the upper annulus of the probe being of increased diameter relative to the lower annulus.
Claim 5
Dependent Claim
40 words
The earth soil sampler according to claim 3, wherein the rigid shaft comprises plural sections, each of which may be removably joined to another, and wherein means in the retainer secure the respective sections for portability of the disassembled sampler.
Claim 6
Dependent Claim
40 words
The earth soil sampler according to claim 2, wherein the rigid shaft comprises plural sections, each of which may be removably joined to another, and wherein means in the retainer secure the respective sections for portability of the disassembled sampler.
Claim 7
Dependent Claim
34 words
The earth soil sampler according to claim 1 wherein the hollow probe defines an interior column of reverse draft, the upper annulus of the probe being of increased diameter relative to the lower annulus.
Claim 8
Dependent Claim
40 words
The earth soil sampler according to claim 6, wherein the rigid shaft comprises plural sections, each of which may be removably joined to another, and wherein means in the retainer secure the respective sections for portability of the disassembled sampler.
Claim 9
Dependent Claim
40 words
The earth soil sampler according to claim 1, wherein the rigid shaft comprises plural sections, each of which may be removably joined to another, and wherein means in the retainer secure the respective sections for portability of the disassembled sampler.
