Abstract: A torque control shutoff clutch (110) for power tools is provided with a torque recovery camming device which assists in decoupling the applied power of the clutch (110) along with the shutting off of the motor (106) driving the power tool. The clutch permits automatic reset of the device upon release of the throttle trigger and further throttles air flow to the power source just prior to shutoff thereby minimizing operator shutoff torque reaction.

Abstract: A device (3) and method for removing debris from a drillhole (1), includes positioning a separator adjacent to a down-the-hole percussive drillhead, for removing water and other matter from the percussive fluid prior to the percussive fluid entering the drillhead. The water and other matter are ejected into the drillhole to remove the debris, and backflow of debris and water into the separator and drillhead is prevented, during periods when the percussive fluid flow ceases.

Abstract: An apparatus (10) has a nozzle (12) including a nozzle orifice (14). There is a first chamber (22) adjacent and immediately downstream of the nozzle orifice (14). A first fluid supply (20) which supplies a first fluid is applied to the nozzle assembly wherein the first fluid passes through the orifice which exits downstream into the first chamber (22). A second fluid supply (28) supplies a second fluid, and is located downstream of said first fluid supply (20) in fluid communication with the first fluid supply (20). A flow limiter limits flow of the second fluid supply to the first chamber (22). The flow limiter may be a third fluid supply (32) applied to the first chamber, located intermediate said first and second fluid supplies. The flow limiter may alternatively be a throat formed (38) in a member, which a fluid jet applied by the first fluid supply passes through.

Abstract: A clutch assembly (16) transmits rotary motion in a percussive apparatus (10) to a drill steel. The clutch assembly (16) includes a first hub (18) having a first cylindrical surface (24) formed thereon. A second hub (20) which is substantially rotationally coupled to the drill steel, has a second cylindrical surface (26) formed thereon. The second cylindrical surface (26) is coaxial with the first cylindrical surface (24). A wrap spring (17) engages a portion of both the first cylindrical surface (24) and the second cylindrical surface (26), wherein relative rotary motion between the first hub (18) and the second hub (20) is permitted in a first direction and restricted in a second direction. The wrap spring clutch (16) transmits motion supplied from a rifle bar assembly as well as a plunger bar arrangement.

Abstract: An oil scavenger system for a face seal (16, 18) including a lubricant scavenger system for retrieving lubricant which has escaped from a first side (14) to a second side (26) of a seal which seals a rotary shaft (10). The rotary shaft (10) is used on a compressor, pump, or any other machine which involves a lubricant seal about a rotary shaft. A cover (24) encases the second side of the seal, producing a first space (26) therebetween. A first pressure is maintained in the first space (26). A second space (14) is interconnected to the first space (26) whereby the lubricant may freely pass therebetween. The interconnection may be mounted exterior or interior of the machine. A second pressure is maintained in the second space (14) than in said first space (26). The second space (14) may actually be in communication with the first side of the seal. The second pressure is less than the first pressure.

Abstract: A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.
