Soil penetration and sampling system
First Claim
1. An apparatus for conducting penetration testing of soils within a bore hole, comprising:
- casing means positionable within the bore hole;
anvil means slidably received within said casing means;
penetration means carried by said anvil means;
hammer means slidably received within said casing means and movable relative to said anvil means; and
means to move said hammer means within said casing means a preselected distance selectively to impart a driving force to said anvil means.

Abstract
A soil penetration testing system for testing soils within a bore hole. The system including a drive-weightassembly (11) positionable with the bore hole (B). The drive-weight assembly (11) has a casing (20) containing an anvil (23), a hammer (33) movable relative to the anvil (23) and a hammer lifter (50) to move the hammer (33) a preselected distance selectively to impact against the anvil (23). A penetration member (26) is carried on the anvil (23) in such fashion to penetrate the soil. A winch line (12) and winch (13) are provided to position the drive-weight assembly (11) within the bore hole (B); and a cathead line (15) also is provided to actuate the drive-weight assembly (11) when positioned within the bore hole (B).

15. An apparatus for conducting penetration testing of soils within a bore hole, comprising:
-
casing means positionable within the bore hole; anvil means slidably received within said casing means; penetration means camed by said anvil means; hammer means slidably received within said casing means and movable relative to said anvil means; lifter means slidably received within said casing means; pivotal latch means selectively to couple said hammer means with said lifter means, said latch means having trip lever means; and trigger means at a predetermined distance from said anvil means within said casing means, said hammer means movable between said anvil means and said trigger means; said trip lever means being engageable with said trigger means selectively to disengage said hammer means from said lifter means, whereby said hammer means imparts a driving force to said anvil means.

16. A soil penetration testing system for testing soils within a bore hole, comprising:
-
a drive-weight assembly positionable within the bore hole, said drive-weight assembly having anvil means, hammer means movable relative to said anvil means, and lifter means to move said hammer means a preselected distance selectively to impart a driving force to said anvil means; penetration means carried by said anvil means for penetrating the soil; first line means secured at one end to said lifter means and the other end being operatively connected to winch means to position said drive-weight assembly within the bore hole; and means for actuating said drive-weight assembly within the bore hole. - View Dependent Claims (17, 18)
