Abstract: A hand brake mechanism of the quick-release type having locking structure preventing accidental brake release includes a clutch collar interconnecting a drive member mounted on a shaft for rotation therewith and a pinion mounted on the shaft for rotation relative thereto and for being operatively connected in a power train to the car brakes. The collar is shiftable on the shaft between a drive position making the aforesaid interconnection, and a brake-release position wherein the connection is broken and the pinion is freely rotatable on the shaft. A pivotally mounted shift lever has collar-engaging members for shifting the collar between such positions. A cam shaft is provided with a cam which, when the cam shaft is rotated in one direction, engages the shift lever to shift the collar into the brake-release position.

Abstract: A break-away tank tee fitting for connecting a well water storage tank to the supply or service line. The tank tee fitting has a unique disconnect arrangement for connecting the service line to either a bottom or side inlet tank. This arrangement allows the tank to be removed and replaced without cutting any pipes or wires. The tank tee fitting also provides a unique arrangement designed to easily accommodate in less space the pump switch and pressure gauge normally found in systems where the fitting is used.
