A finger and hand exerciser includes a housing defining four chambers arranged side-by-side in parallel with one another. Each chamber receives a tension adjustment member, a plunger that is reciprocatingly slidable in the chamber, and a helically wound compression spring extending between the plunger and the tension adjustment member. Each tension adjustment member includes a knurled wheel which the user of the finger and hand exerciser may turn to decrease or increase the force the spring exerts on the plunger.

Finger and hand exerciser with tension adjuster

A hot water shut off valve for use for domestic household water shower use which shuts off excessively hot water. The valve generally includes an water inlet source opening to an inner chamber. The inner chamber has an outlet source at the base of said chamber, a sealing means communicating with said outlet sources for alternately turning on or off the flow of water from said inlet sources through said outlet sources. The sealing means is urged against the base of said mixing chamber by means of a paraffin power element communicating with a spring. In the preferred embodiment, a reset member is provided to reset the flow of warm water from the inlet source to the outlet source.
