Abstract: A limiter torque wrench and method having a handle and a jaw pivotally connected together along an axis and for pivoting of the handle upon applying a quantifiable torque. A cam and spring-loaded follower are interconnected between the handle and the jaw. A ratchet is connected to the cam for return of the cam to a starting position and with minimal torque and after application of the limited torque. There is a second ratchet engagable with a workpiece and a pawl engages the second ratchet and a pusher engages the pawl offset from the axis for optimum engagement force on the engaged pawl.
Abstract: A torque-limiting driver. The driver comprises a handle having a housing, a drive assembly located the housing. The drive assembly comprises a drive, a drive clutch member supported by the drive shaft and secured to the housing, a camming clutch member supported by the drive shaft and interacting with and biased against the drive clutch member. The camming clutch member is coupled to the drive shaft. The housing has a first open end and a second open end. The drive assembly is locked or secured together at the first open end, and the drive assembly is connected to a tool at the second opening.
Abstract: A holder for replaceable tools, including a body with an axial opening extending along an axis and for releasably receiving the tools and having two radial openings with balls therein extending into the axial opening. Two ramps are movable on the body and they engage the balls for forcing the balls onto the tool being held in the body and thereby radially and axially stabilize the tool in the body. Two separate springs engage the ramps for movement of the ramps separate from each other.
Abstract: A torque limiting and ratcheting driver having a housing and a torque limiting assembly located within the housing. The torque limiting assembly includes a cam member, a plunger, and a roller supported by the plunger that interacts with the cam member. The ratcheting assembly is located interiorly of the cam member.
Abstract: A clutch assembly for use with a torque limiting driver. The clutch assembly comprises two relatively roatable clutch plates, a driving plate and a camming plate, that face one another, with a plurality of rolling members housed between the two members. When the rolling members are in the override position, the recesses form individual housings for the rolling members that include a gap located between the rolling members and a respective curvilinear base area of the drive plate. The clutch assembly is secured to a drive shaft by a pin, which is supported by a pair of wheels located on opposing sides of the pin.
Abstract: An adjustable, torque-limiting driver for a tool having a radially extending handle that houses a cam member and a pair of plungers. The plungers are biased against the housing and provide variable resistance for the cam member. The arrangement of the cam member and the plungers reduces the wear on the various parts of the driver and extends the life of the driver.

Abstract: A method for assembling a torque-limiting driver, and the resulting drive. The method comprises the steps of providing a handle having a housing, drive assembly, and a testing assembly. The drive assembly is assembled, inserted into the testing assembly and calibrated. The drive assembly is then removed and inserted into the housing of the handle and secured to the handle.
