Definitions

  • ABSTRACT A knife component for push-pull type earth coring includes a central shaft and a surrounding shroud or shell held concentrically to the shaft by a plurality of cutter blades or webs.
  • the shroud or shell tapers from the front to the back to compress the cut core slightly and the rear side of the cutter blades are provided with offset teeth to thrustably engage the core during the core pushing or extruding phase;
  • This invention overcomes these disadvantages by providing a knife cutter assembly which can be used with apparatus and methods described in the above patents, under circumstances of heavy suction and relatively loose or porous soil.
  • the principal object and essence of the invention is to provide a knife cutter for such earth coring which, as the core is formed and segmented by the cutter, compresses the core considerably thus reducing the suction and increasing the adhesion of the earth forming the core, and which furthermore includes means to thrust against'the face of the core during the extruding action and reduces the tendency of the cutter to embed within the core during this action.
  • Another object of the invention is to provide a device of the character herewithin described,-in conjunction with the foregoing object which includes offset thrust teeth formed on the rear side of the cutter blades which engage the face of the core during the thrusting or extruding action.
  • a yet further object of the invention is to provide a device of the character herewithin described which enables the device and processes described in the above patents, .to be used on soils of relative porosity and/or heavy suction.
  • a yet further object of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture,
  • the present invention consists of the inventive concept which is comprised, embodied, embraced, or included in the means, method, process, product, construction, composition, arrangement of parts, or new use of any of the foregoing, herein exemplified in one or more specific embodiments of such concept, reference being had to the accompanying drawings in which:
  • FIG. 1 is an isometric view of the cutter knife component.
  • FIG. 2 is a vertical section of FIG. 1.
  • FIG. 3 is a view substantially along the lines 3-3 of FIG. 2.
  • reference character 10 illustrates a central shaft being threaded at either end 11 and 12 by which means it may be connected along the run of push-pull types or the like nonnally used in this form of earth coring. Inasmuch as these connections are illustrated and described in the above mentioned patents, it is not believed necessary to show same in the present application.
  • a shroud or a shell 13 Concentrically surrounding the shaft 10 is a shroud or a shell 13 which is in the form of a substantially truncated cone having a larger diameter end 14 adjacent one end 11 of the shaft 10 and a narrower diameter end 15 adjacent the other end 12 of the shaft 10 as clearly shown in the drawings.
  • the shell or shroud 13 is maintained in concentric relationship spaced from the shaft 10, by means of a plurality of cutter knives or means collectively designated 16 and these are in the form of substantially rectangular flat plates secured by one end to the exterior of shaft 10 and by the other ends thereof to the interior 17 of the shell or shroud 13, once again as clearly shown.
  • edges l9are edge sharpened as at 21 and edges 20 are provided with a plurality of oppositely offset thrust teeth 22 as clearly shown in FIGS. 1 and 3.
  • the narrower diameter end 15 of .the shell 13 inclines inwardly slightly and is provided with serrated teeth 23 which forms striations on the earth core formed by the I cutter knife.
  • the cutter knife is first drawn through a pilot hole, in the earth, in the direction of arrow 24 as illustrated and described in the above mentioned patents, so that the larger diameter edge I4, which is edge sharpened as at 24, forms a core and the cutter blades 18 segment this core.
  • the narrower diameter end 15in conjunction with the serrated teeth 23 compresses this core as it is formed and forms striations on the outer surface both of which reduce the suction between the core and the surrounding earth, as the core is formed.
  • a cutter knife for push-pull type earth coring comprising in combination a central shaft for attaching the cutter knife to associated driving rods, a surrounding shell, and knife means extending between said shaft and said shell to maintain said shell concentrically spaced from said shaft, said shell being in the form of a truncated cone, with the narrower diameter in adjacent one end of said shaft and the wider diameter in adjacent the other end of said shaft, said knife means being edge sharpened on the edge adjacent said wider diameter end.
  • said knife means takes the form of a plurality of flat plate members secured by the ends thereof to the interior of said shell and to the exterior of said shaft, said plate members being aligned with one edge adjacent said wider diameter end of said shell and the other edge adjacent said narrower diameter end of said shell, said edge adjacent said wider diameter end of said shell being edge sharpened, said edge adjacent said narrower diameter end of said shell being provided with offset thrust teeth formed on said edge to facilitate thrusting engagement of said cutter knife against the core of soil cut thereby.
  • said knife means takes the form of a plurality of flat plate members secured by the ends thereof to the interior of said shell and to the exterior of said shaft, said plate members being aligned with one edge adjacent said wider diameter end of said shell and the other edge adjacent said narrower diameter end of said shell, said edge adjacent said wider diameter end of said shell being edge sharpened, said edge adjacent said narrower diameter end of said shell being provided with offset thrust teeth formed on said edge to facilitate thrusting engagement of said outer knife against the core of soil cut thereby.
  • said knife means takes the form of a plurality of flat plate members secured by the ends thereof to the interior of said shell and to the exterior of said shaft, said plate members being aligned with one edge adjacent said wider diameter end of said shell and the other edge adjacent said narrower diameter end of said shell, said edge adjacent said wider diameter end of said shell being edge sharpened, said edge adjacent said narrower diameter end of said shell being provided with offset thrust teeth fonned on said edge to facilitate thrusting engagement of said outer knife against the core of soil cut-thereby.
