Patent number: 10337782Abstract: Disclosed is a fan gun snowmaker that utilizes an external nucleation device to create atomized water mist that is broken apart and frozen by a transverse air jet to create frozen nuclei, or snow seed. Further, flat spray nozzles that are normally used for spray washing and power washing are used that create a flat fan spray at the opening of the fan gun, rather than typical cone-shaped sprayers. The fan spray better disperses the water molecules into the cold, ambient air, which then combine with the frozen nuclei to create snowflakes. The fan gun is portable and lightweight and has anchors at each end that also function as jacks.Type: GrantFiled: April 13, 2017Date of Patent: July 2, 2019Assignee: Snow Realm Holdings, LLCInventor: Tad Beaulac

Patent number: 6408962Abstract: A convertible sled can be dragged silently into the woods by the hunter. Once the hunter has bagged his game, he converts the sled into a track-driven and battery-powered cart. The sled portion is at the bottommost part of the assembly on the way into the woods. In this “sledding” mode, the battery pack, the tracks and the frame are situated above the sled. In the “carting” or “track-driving” mode, the sled is detached from the assembly and is remounted above the frame, tracks and battery pack. In this mode, the sled forms a platform upon which the game can be secured. In the carting mode, the hunter activates the track-driven cart to assist with extraction of the game. Activation of the track-driven cart is by means of a handle which extends to the front of the assembly. An alternative embodiment includes a pair of removable wheels mounted to a pair of adjustable wheel supports, which wheels may be used to roll the convertible sled as well.Type: GrantFiled: April 21, 2000Date of Patent: June 25, 2002Inventor: Jason Ryckman
