Abstract: Some embodiments include an axial flow pump for a activity pool. An axial flow pump, for example, may include a water reservoir and a pump body disposed within the water reservoir. The pump body may include a shaft seal, a water flow intake, and a water flow output. The axial flow pump, for example, may also include an impeller disposed within the pump body between the water flow intake and the water flow output; an electric motor disposed external to the pump body and external to the water reservoir and a shaft that is coupled with the electric motor, extends into the pump body through the shaft seal and is coupled with the impeller such that the electric motor rotates the impeller causing water to flow into the pump body through the water flow intake and forcing the water to exit the pump body through the water flow output.

Abstract: Some embodiments include an activity pool comprising: a pool and an axial flow pump. The pool may comprise an activity pool reservoir comprising a top opening and a depth; and a water reservoir comprising a depth greater than the usable pool depth. The axial flow pump may be disposed within the water reservoir. The axial flow pump may comprise: a water intake disposed near or at the bottom of the axial flow pump; a water flow channel fluidically connected with the water intake; a motor; an impeller disposed at least partially between the water intake and the water flow channel; an impeller shaft coupled with the motor and the impeller, the impeller shaft extending from the motor to the impeller though the water flow channel; and an output disposed between the motor and the water flow channel, the output fluidically connected with the water flow channel and the usable pool.

Abstract: Some embodiments include an activity pool comprising a pool volume having a top opening and a depth; and an activity deck disposed within the pool volume, the activity deck is moveable in a vertical direction between at least two configurations, the activity deck comprises a composite material; and a plurality of screw jacks coupled with the activity deck, the plurality of screw jacks move the activity deck between the at least two configurations, the plurality of screw jacks being coupled together with a one or more motor that engages each of the plurality of screw jacks via one or more worm gears.

Abstract: Some embodiments may include an activity pool comprising a pool, an activity deck, a plurality of screw jacks, and an axial flow pump. In some embodiments, the activity deck may be disposed within the activity pool reservoir and may be moveable in a vertical direction between at least two configurations. In some embodiments, the plurality of screw jacks may be coupled with a bottom side of the activity deck, the plurality of screw jacks may move the activity deck between the at least two configurations. In some embodiments, the axial flow pump may be disposed within a water reservoir and may force water through the axial flow pump and into a usable pool.

Abstract: A bobbin winder which can be mounted in the flyer bearings and can be driven by the belt of the spinning wheel and upon which a bobbin spool may be mounted so as to wind thread or yarn by using the drive of the spinning wheel.

Abstract: A campfire griddle or grill which is designed for convenience and cooking over a campfire. A metal support in the form of a stake is driven into the ground by stepping on a foot pad and the griddle handle is then placed over the stake and lowered to the desired height. The handle can be adjusted to different heights by depressing the safety latch while lowering and the griddle can be swung away from the fire as desired. The griddle itself can easily be attached or removed from the handle. It can also be used alone on a camp stove if desired. A charcoal pan can also be attached to the stake under the griddle so that charcoal can be placed in such charcoal pan to heat the griddle or grill after it has been placed on the supporting stand.
