Patent number: 5987698Abstract: An apparatus for preventing the slinging of the slop, or slurry, which results from the use of liquids such as water during cutting, coring, or drilling operations on concrete and other strata. A shield fits around the cutting element and is positioned closely enough to a vacuum ring to effectively close off the area around the strata which is being cut or cored so as to contain the slop that is flung about by the cutting element. The vacuum ring is coupled to a wet/dry vacuum so that when a vacuum is applied into the area which is closed off around the strata which is being cut, the slop is suctioned into the vacuum ring and on through a hose into the vacuum.Type: GrantFiled: February 7, 1997Date of Patent: November 23, 1999Assignee: MDI Labs, Inc.Inventors: Arthur S. Koenig, Victor Y. Gonzales

Patent number: 5839522Abstract: A slurry diverter for use in well drilling of the type in which a drill shaft is rotated to drill a bore into the ground includes a housing having a top end with an upper surface and a first aperture within the top end of the housing. The housing also has a second aperture which permits entry of slurry from the drilling bore into the housing. The first and second housing apertures are aligned with the bore during use and permit the drill shaft to pass through the housing. The housing also has an exit port which permits slurry to exit the housing so that the slurry can be diverted away from the drilling site. The slurry diverter further comprises at least one flexible wiper positioned above the upper surface of the top end of the housing. The wiper has a central aperture which is coaxially disposed with the first housing aperture. The wiper seals with the drill shaft such that substantially none of the slurry entering the housing can pass through the first housing aperture.Type: GrantFiled: September 16, 1997Date of Patent: November 24, 1998Inventors: John F. Allyn, Walter G. Allyn

Patent number: 5660240Abstract: A water and dust collector for the bit of a wet core drilling operation. The device comprises a dome-shaped element with a hole in its top to receive the core bit with relatively close clearance, and an annular planar bottom edge adapted to rest upon the surface being drilled, about the drilling site. The device has an outlet tube assembly near its bottom edge for connection to a wet-dry vacuum system, and at least one air inlet formed in the annular bottom surface substantially opposite the outlet tube assembly.Type: GrantFiled: June 7, 1995Date of Patent: August 26, 1997Inventors: Gregory W. Harms, Keith W. Harms

Patent number: 5655610Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: August 12, 1997Inventor: Todd M. Skinner

Patent number: 5647444Abstract: A rotating blowout preventor having at least two rotating stripper rubber seals which provide a continuous seal about a drilling string having drilling string components of varying diameter. A stationary bowl is designed to support a blowout preventor bearing assembly and receives a swivel ball that cooperates with the bowl to self-align the blowout preventor bearing assembly and the swivel ball with respect to the fixed bowl. Chilled water is circulated through the seal boxes of the blowout preventor bearing assembly and liquid such as water is pumped into the bearing assembly annulus between the stripper rubbers to offset well pressure on the stripper rubbers. Lubricant is pumped into shaft bearings and serves to prolong the life of shaft. pressure seals by offsetting well pressure against the shaft pressure seals and clamp mechanisms are used to tighten the stripper rubbers on the respective mounting elements in the bearing assembly and swivel ball.Type: GrantFiled: August 23, 1996Date of Patent: July 15, 1997Inventor: John R.

Patent number: 5348107Abstract: A system for maintaining an optimum pressure balance within an inner chamber of a drilling head for improved seal life and integrity. The system maintains a pressure differential across the seals thereby preventing well fluids from contaminating the seals and improving their useful life. The drive ring of a drilling head is rotatably supported by a series of bearings disposed within a bearing chamber. The secondary chamber of the drilling head is sealed to prevent contaminants from entering the chamber and fouling the seals. The seals withstand the borehole well pressures to prevent the introduction of contaminants, by maintaining a pressure differential across the seals. The present system compensates for variations in the borehole pressure. A pressure compensator is in communication with the borehole to activate a lubricant pump for increasing lubricant pressure within the inner chamber in response to increased borehole pressures.Type: GrantFiled: February 26, 1993Date of Patent: September 20, 1994Assignee: Smith International, Inc.Inventors: Thomas F. Bailey, Larry F. Moeller, John E. Campbell
