Patent number: 9049955Abstract: A smokeless stovetop grilling device includes a grilling surface, a catch tray a manifold and a pressurized fluid source. The grilling surface has a plurality of upward pointing V-shaped first members attached at first and second ends to a first supporting frame. The catch tray has a plurality of hollow core downward pointing V-shaped second members attached at first and second ends to a second supporting frame. Adjacent pairs of the side edges of the first and second members are spaced from one another by a first distance. The first supporting frame is located over the second supporting frame such that drippings from the grilling surface fall into the catch tray. The pressurized fluid source forces cooling fluid through the second members, preventing the catch tray from smoking. A heat conducting element has upward pointing third members extending upwardly between the second members to heat undersides of the first members.Type: GrantFiled: March 5, 2012Date of Patent: June 9, 2015Inventor: Stephen Coutts

Patent number: 8151699Abstract: A stovetop grilling device includes a catch tray that has a plurality of downward pointing V-shaped first members attached to a first frame and having parallel side edges spaced from one another by a first distance. A grilling surface has a plurality of upward pointing V-shaped second members attached to a second frame and having parallel side edges spaced from one another by the first distance. The second frame is located over the first frame with a mid-point between the parallel side edges of each of the first members centrally located between and below the parallel side edges of two adjacent second members and a mid-point between the parallel side edges of each of the second members centrally located between and above the parallel side edges of two adjacent first members. Heat follows an angled path upward to the grilling surface and food drippings flow downward to the catch tray.Type: GrantFiled: February 20, 2009Date of Patent: April 10, 2012Inventor: Stephen Coutts

Patent number: 7836619Abstract: An inflatable flag display includes a shaft having a hollow core and a sealed upper end. An aperture is located in the upper portion of the shaft and penetrates from an outer surface to the hollow core. A supporting base is connected to the shaft. A gas input connection is affixed to the shaft or the base and is in fluid communication with the core. An inflatable flag member is affixed to the shaft, formed of flexible material and has at least one inflatable chamber. The chamber is in fluid communication with the aperture and has an exhaust vent. A compressed gas source is in fluid communication with the gas input connection. A compressed gas modulator controls pressure or duration of gas flow, causing the flag to undulate. A variant includes means for rotating the shaft as the flag is inflated. Another variant includes an inflatable column replacing the shaft.Type: GrantFiled: November 11, 2008Date of Patent: November 23, 2010Inventor: Stephen Coutts

Patent number: 7430849Abstract: A conveyor chain pin remover includes a gear case with an attached handle, an actuating lever, a ratchet mechanism engaged by the actuating lever and first and second aligned passthrough openings. A retaining bar, is attached adjacent a first end to the gear case and has a chain retaining fixture located adjacent a second end. The chain retaining fixture has a barrier portion located orthogonally to the retaining bar and has a central aperture located in the barrier portion. A ram has a pin punch portion located at a first end and a rack portion extending substantially from a second end toward the pin punch portion. The rack portion fits slidably through the first and second aligned passthrough openings with teeth of the rack portion engaging the ratchet mechanism. The pin punch portion fits slidably through the central aperture and is smaller in diameter than pins of a roller chain.Type: GrantFiled: May 16, 2008Date of Patent: October 7, 2008Assignee: Practical Inventions, LLCInventors: Stephen Coutts, Sanford Fitelson
