Abstract: The present invention provides a clutch bleeder tool assembly to force air bubbles from a clutch hydraulic control assembly of a standard vehicle transmission. The clutch bleeder tool assembly includes an adaptor cap to replace the factory cap on the hydraulic fluid reservoir of the clutch assembly. The adaptor cap has a hose attached at one end to the adaptor cap. The other end of the hose is attached to a bulb pump having a check valve. When the bulb pump is operated a positive pressure is maintained in the fluid reservoir. The hydraulically closed clutch hydraulic control assembly is opened at the slave cylinder to allow air bubbles to be forced out, so that proper operation of the clutch hydraulic control assembly is maintained when the hydraulic fluid reservoir is filled and the factory cap is reinstalled.

Abstract: The ratchet wrench of this invention includes a jaw adjustment assembly connected with a jaw and gear assembly carried by a wrench head. Components of the jaw adjustment assembly include a scroll plate inside a cap operated by a jaw adjustment disk located above the cap. The jaw adjuster disk is connected with the scroll plate using a snap ring. Components of the jaw and gear assembly include a pair of jaws supported and guided inside a gear unit with the aid of parallel support rails. The support rails connect the rear unit with the jaws and support the jaw and gear assembly from a wrench head and handle. The two assemblies are pressed and held together by a splined inner surface of the cap interfacing with a splined outer surface of the gear unit. A typical pawl assembly provides the ratchet operation of the ratchet wrench.

Abstract: A fan unit being suspended from a building floor structure within a crawl space. The fan unit includes a fan, a fan motor, an inlet grill, a discharge plenum and an outlet grill. A timer connected in the power supply activates the fan motor at periodic predetermined time intervals to move the crawl space air through the fan unit. The fan unit is located and orientated to create a negative pressure to pull air into the crawl space through wall inlet grills and to also create a positive pressure to force air out of the crawl space through wall outlet grills. An outside humidity sensor can be used to insure the outside air has a lower percent humidity than that desired in the crawl space and an inside humidity sensor is used to turn the fan unit off if the crawl space humidity is below an acceptable limit.
