Patent number: 8540171Abstract: In a preferred embodiment of the present invention a sprinkler is provided, having a first shaft coupled to a drive mechanism and a grooved deflector. A second shaft is disposed within the first shaft, coupled to a water flow adjustment mechanism and an adjustment region on the top of the deflector. The first shaft transfers rotational movement from the drive mechanism to a grooved deflector on the top of the sprinkler. The second shaft rotates with the first shaft during normal operation due to a friction clutch within the sprinkler. When the user desires to adjust the water flow (i.e., the radius of the water), the friction of the clutch can be overcome by rotating the second shaft, increasing openings of flow passages within the sprinkler body. In this respect, flow adjustments can be made from the top of the sprinkler while the deflector rotates.Type: GrantFiled: August 30, 2011Date of Patent: September 24, 2013Assignee: The Toro CompanyInventors: Steven C. Renquist, Peter Janku, Richard C. McClure, Saroj Manandhar

Patent number: 6081938Abstract: A flush valve is adapted to be mounted in the tank of a toilet and includes a selector assembly and a flush valve. The selector assembly is accessible from outside the toilet and provides for initiation of the flushing operation and an alternative choice between a larger flush water volume and a smaller flush water volume. A support structure provides for both axial and radial movement of the selector assembly relative to the flush valve in order to facilitate mounting and alignment of the flush valve assembly. A slide mechanism provides for variation of at least the smaller flush water volume.Type: GrantFiled: September 14, 1998Date of Patent: July 4, 2000Assignee: FluidMaster, Inc.Inventors: Richard C. McClure, John C. McKay, Miguel C. Garcia

Patent number: 5797538Abstract: Apparatus for applying a plurality of surgical fasteners to body tissue includes an elongated body extending from a handle assembly. A fastener cartridge housing pivotably connected to a distal portion of the elongated body receives a fastener cartridge containing a plurality of surgical fasteners. A fastener driving mechanism actuatable from the handle assembly ejects fasteners from the fastener cartridge to form them against an anvil mounted adjacent the cartridge housing. The fastener cartridge is pivotably movable from a position in alignment with a longitudinal axis of the elongated body to a position out of alignment with the elongated body. Visual indication of the relative position of the fastener cartridge is provided by a control lever which is movable toward and away from the handle assembly to correspond with movement of the fastener cartridge. A clamp mechanism is also provided to move the anvil relative to the cartridge housing to clamp tissue therebetween.Type: GrantFiled: March 13, 1997Date of Patent: August 25, 1998Assignee: United States Surgical CorporationInventors: Lisa W. Heaton, Mitchell J. Palmer, Keith L. Milliman, Richard C. McClure

Patent number: 5699563Abstract: A dual flush valve that can be operated in a partial flush mode to release only about half of the tank water to the toilet bowl, or in a full flush mode to release almost all of the tank water, is of simple and reliable construction. For a partial flushing a chain device (64, FIG. 2) connected to the outer end of the flush member, is pulled to raise the flush member only a small amount (to 14C), and a release mechanism (90) is connected to a separate location on the flush member to keep it up until a float (110) senses that about half of the tank water has been released. The float pivots an arm (102) to disengage a latch 94 on the arm from a catch (96) on the yoke of the flush member to release it. The float slides along the refill/overflow tube (26).Type: GrantFiled: July 3, 1996Date of Patent: December 23, 1997Assignee: Fluidmaster, Inc.Inventor: Richard C. McClure
