Abstract
Abstract An earth core sampler comprises an elongated body with an elongated sampling member eccentrically mounted therein and movable by a handle against a spring between an open position in which a scraping edge projects from the sampler and a closed position; an earth sampling groove is provided in the sampling member immediately adjacent the scraping edge; the device is driven into the ground by any suitable means, as for example by a vibratory hammer attached to one end, and the sampling member opened while the sampler is rotated to scrape earth from the bore wall and form a sample in the groove; the sampling member is then closed and the sampler withdrawn from the bore. The elongated sample that is obtained is representative of the whole length of the bore.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
An earth core sampler comprising an elongated body having a longitudinal axis adapted to be driven into the earth in the direction of the longitudinal axis to form therein an earth sample bore, the body having an elongated groove therein extending parallel to the said longitudinal axis, an elongated sampling member rotatably mounted by the body in the elongated groove for movement between open and closed positions, the sampler providing in said open position of the sampling member a scraping edge protruding therefrom to engage with the wall of the bore upon rotation of the sampler in the bore and to gather an elongated earth sample from said bore wall, and the body and the sampling member cooperating in said closed position to provide a closed sample chamber within which the gathered elongated soil sample is enclosed for intact withdrawal of the sample from the bore.
Claim 2
Dependent Claim
146 words
An earth core sampler comprising an elongated body having a longitudinal axis adapted to be driven into the earth in the direction of the longitudinal axis to form therein an earth sample bore, the body having an elongated groove therein extending parallel to the said longitudinal axis, an elongated sampling member rotatably mounted by the body in the elongated groove for movement between open and closed positions, the sampler providing in said open position of the sampling member a scraping edge protruding therefrom to engage with the wall of the bore upon rotation of the sampler in the bore and to gather an elongated earth sample from said bore wall, and the body and the sampling member cooperating in said closed position to provide a closed sample chamber within which the gathered elongated soil sample is enclosed for intact withdrawal of the sample from the bore.
Claim 3
Dependent Claim
81 words
A sampler as claimed in claim 1, wherein the said elongated body is of crescent transverse cross section, and the sampling member is mounted for rotation about a longitudinal axis parallel to and transversely displaced from the longitudinal axis of the elongated body, the sampling member in said closed position lying within a circular extension of the external arc-shaped circumference of said crescent cross section for ease of insertion of the sampler into the said bore and its subsequent withdrawal therefrom.
Claim 4
Dependent Claim
38 words
A sampler as claimed in claim 2, wherein the said scraping edge is provided by the sampling member and the sample chamber is constituted by an elongated groove provided in the sampling member immediately adjacent the scraping edge.
Claim 5
Dependent Claim
30 words
A sampler as claimed in claim 3, and comprising spring means connected between the body and the sampling member and operative to urge the sampling member to the closed position.
Claim 6
Dependent Claim
38 words
A sampler as claimed in claim 1, wherein the said scraping edge is provided by the sampling member and the sample chamber is constituted by an elongated groove provided in the sampling member immediately adjacent the scraping edge.
Claim 7
Dependent Claim
30 words
A sampler as claimed in claim 1, and comprising spring means connected between the body and the sampling member and operative to urge the sampling member to the closed posiTion.
Claim 8
Dependent Claim
31 words
A sampler as claimed in claim 1, in combination with a vibrating hammer connected to the upper end thereof for driving the sampler into the earth and for its removal therefrom.
