Abstract: Apparatus for permitting exercise by a bedridden patient includes a patient bed having guard rails extending generally along one side and with a bracket supported by the rails. A motor is carried by the bracket, the motor having a drive shaft extending generally normal to the rails and toward the bed. A crank arm is fixed at one end to the drive shaft and dimensioned substantially shorter than the distance between the drive shaft and the surface of the bed, with a handle or footstrap at the other end of the crank arm for permitting a hand or foot of the patient to be coupled to the crank arm so that the patient may exercise by rotation of the crank arm and the drive shaft.

Abstract: A fire extinguishing system is automatically actuated in response to flames from a fire on the upper surface of a stove having a vent hood. A pressurized fire extinguisher includes a lever actuated valve spring biased to the open position and contains a supply of fire extinguishing material. A discharge manifold extends between the valve of the fire extinguisher and a plurality of nozzles which are positioned within the vent hood to distribute the fire extinguishing material over the upper surface of the stove when the valve is released into the open position. A fusible link secures a strut which maintains the valve in a closed position. A fuse extends from an area above the upper surface of the stove to a capsule of gun powder which surrounds the fusible link. A fire in the stove top area ignites the exposed end of the fuse which controllably transfers fire to the capsule of gun powder.
