| 86 | Auger cleaner | US474981 | 1995-06-07 | US5655610A | 1997-08-12 | Todd M. Skinner |
| An apparatus is provided for cleaning dirt and debris from the stem and flighting of an earth boring auger. The auger cleaner apparatus has an opposed pair of blade assemblies which are brought into mechanical engagement with the stem and flighting of the auger. Once the auger cleaner is engaged about the auger, the user of the apparatus then need only rotate the auger cleaner about the auger to strip off dirt and debris. The auger cleaner has handles which provide mechanical advantage to the user for causing the device to rotate about the auger. The device may be provided with selectively exchangeable blade assemblies for adapting the auger cleaner for use on augers of different sizes and of different manufacturers. | ||||||
| 87 | Cleaning device for earth augers | US848352 | 1992-03-09 | US5242027A | 1993-09-07 | Kenneth J. Blum |
| Apparatus (30) is disclosed for preventing accumulation of debris such as clay, dirt or stones in the flighting (28) of an elongated earth auger (12) so that when the auger is removed from a bore hole while continuing to rotate, accumulated debris is not left in the flights which could fall on adjacent workmen or equipment. The apparatus includes a fan-shaped flight cleaning device (76) having a rotatable hub (80) which carries a series of radially extending, co-planar petal elements (82) adapted to successively extend into the auger flighting to dislodge debris tending to accumulate in the flights. As the auger rotates, the flighting engages the edges of the petal elements to cause the cleaning device to rotate and successively bring the petal elements into the area between adjacent flight sections for dislodgement of debris tending to accumulate in such areas. Pivotal mounting means (60, 84) for the flight cleaning device (58) allows the device to be deflectable as necessary to clear cylindrical connector collars of the auger, or to swing out of the way when a debris dislodgement element encounters debris wedged in the auger flighting that could damage the cleaning device. | ||||||

| 93 | Cylinder type soil-sampling auger | US3760893D | 1972-04-03 | US3760893A | 1973-09-25 | MEEKER R |
| A soil-sampling auger of cylindrical tubular form with a leading open end in the form of an auger bit. The tubular auger consists of two substantially semicylindrical sections pivoted together at the trailing or closed end so that the sections can be swung apart to expose or remove the soil sample after the auger has been turned into the ground and then pulled out of the ground with the entrapped soil sample. The pivot arrangement between the sections is so designed that turning the auger into the ground exerts a force which keeps the sections closed.

| 94 | Gage scraper | US3674314D | 1970-01-07 | US3674314A | 1972-07-04 | SCARAVILLI JOSEPH V |
| A tunneling machine is disclosed which includes a support frame, a rotatable cutter head, and inside roller cutters and gage roller cutters for cutting or crushing the end face of a tunnel. Each gage cutter is provided with a gage scraper which includes a first scraper portion for engaging the tunnel end face and a second scraper portion for engaging the cylindrical tunnel wall to clear protruding formation particles from the path of the gage cutter. A resilient mounting means resiliently biases the first and second scraper portions against their respective tunnel surfaces to provide substantially continuous contact therewith as the scraper portions become worn, and to permit retraction of the scraper portions if they encounter a formation particle which they cannot remove. A guide plate prevents movement of the resiliently mounted scraper portions toward the gage cutters in the direction of travel of the gage cutters around the tunnel end face to permit mounting the scraper portions on gage saddles immediately adjacent the gage cutters. Intersecting edge portions of the guide plate form fixed scrapers for further protection of the gage cutters.
