Patent number: 5038869Abstract: The fatigue-resistant spindle end of the invention is an elongated body having an axis of rotation. The spindle end comprises a drive engaging portion at one end, a male tool engaging tang at the other end, and a torque transfer section disposed therebetween. The torque transfer section includes a cylindrical journal portion and a frustoconical transition portion. The transition portion retains the geometric characteristics of both the tang and the cylindrical journal portion and blends those geometric characteristics so as to eliminate sharp discontinuities which may function as stress concentrators. In one embodiment of the invention, a stop barrel is also included to prevent a socket or other tool from engaging the transition portion.Type: GrantFiled: July 24, 1989Date of Patent: August 13, 1991Assignee: Snap-on Tools CorporationInventor: Gene E.

Patent number: 4794828Abstract: The mechanism, used in a ratchet wrench, includes a body carrying an integral stud. A bore extends axially into both and an actuator rod is reciprocally mounted therein. A transverse bore in the stud slidably holds a pin which is linked to the rod. A socket is applied to the mechanism by pushing the socket against a camming surface on the pin to enable the socket to be snapped onto the pin without operating the actuator. The socket is removed by depressing the actuator.Type: GrantFiled: December 19, 1983Date of Patent: January 3, 1989Assignee: Snap-on Tools CorporationInventor: Gene E. Olson

Patent number: 4441021Abstract: The probe includes a tubular housing having a first portion and a second portion. The first portion is adapted to be mounted in place of the glow plug of a selected engine cylinder. A light pipe within the first portion directs light from the combustion zone to a phototransistor within the second portion. The front of the first portion has a reduced size aperture defined by an internal shoulder against which the front of the light pipe is seated. The rear of the first portion carries resilient sealing means which is deformed when the second portion is telescoped thereon so as to provide a detachable, frictional, light-tight thermally insulated connection therebetween. A phototransistor is mounted within the second portion to convert light passing through the light pipe into electrical signals. A cable carries these electrical signals to processing equipment. A base resistor is located in the second portion between the base of the phototransistor and the cable.Type: GrantFiled: July 23, 1981Date of Patent: April 3, 1984Assignee: Snap-on Tools CorporationInventors: Gene E.

Patent number: 4402222Abstract: A first signal at a first frequency which is a selected harmonic of the resonant frequency of a bolt in a first loaded condition is determined. Then there is determined a second signal at a second frequency being the same harmonic of the resonant frequency of the bolt in a second loaded condition. Both frequencies are multiplied by a factor M. The up input of a counter receives one of the signals for a predetermined duration, and the down input receives the other signal for the same duration. The number of pulses remaining in the counter is representative of the difference in load between the first and second loaded conditions.Type: GrantFiled: January 26, 1982Date of Patent: September 6, 1983Assignee: Snap-on Tools CorporationInventors: Gene E.
