Assignee:

Snap-On Incorporated - Kenosha WI

International Classification:

B25B 7/10
B25B 7/04

US Classification:

81416, 81411

Abstract:

There is disclosed herein an improved adjustable tool, such as a pair of pliers, having a first jaw portion and a second jaw portion, the first and second jaw portions being pivotably connected to one another by a pivot pin attached in any manner to one of the jaw portions and fitted within a channel defined within the other of the jaw portions. Preferably, the channel is formed by a plurality of pivot centers, including two non-adjacent terminal centers and at least one intermediate center, each center being connected to at least one other center by a slot to form a single pathway such that travel of the pivot pin between non-adjacent pivot centers requires travel through at least one intermediate pivot center, and the pivot pin has a positive tactile indication when properly seated in each pivot center.

Glenn A. Kaufman - Kenosha WI, US

International Classification:

B25B 13/06

US Classification:

811245, 81450

Abstract:

A swivel adapter comprising a first member having a longitudinal axis, a first recess at one end thereof and an outer surface, first and second apertures disposed at diametrically opposing locations on the first member and communicating with the first recess, a second member having a proximal end disposed within the first recess and a distal end, a first bore disposed substantially adjacent to the proximal end that extends transversely through the second member and is substantially coaxial with the first and second aperture, a pin having first and second ends axially disposed in the first aperture, second aperture and first bore, wherein the first and second members are adapted to pivot relative to each other about the pin, and a first weld fixedly attaching the first end of the pin to the outer surface of the first member adjacent to the first aperture.

G01L 524

US Classification:

7386223

Abstract:

A torque wrench having a torque plug integral with the back side of the torque wrench handle and with strain sensing elements mounted on the torque plug and connected to signal processing circuits supported by the handle which control a digital display unit mounted on the handle. The processing circuits include a peak hold detector enabling display of the peak torque value during a torquing operation, and a peak hold response delay insuring capture of the peak torque value.

International Classification:

A47B 5500

US Classification:

312263

Abstract:

A tool cabinet is formed without the use of fasteners or weldments by providing back and side panel sections in an integral unit having top and bottom flanges, and separate top and bottom panel sections having attachment flanges adapted to be interfitted with the flanges on the back and side panel unit to form an open-front housing. Three continuous loop frame members are spaced apart front-to-back inside the housing and are adhesively secured to the top, bottom and side panel sections and support drawer assemblies mounted in a front opening. A lock bar guide is adhesively secured to the back panel section and receives a lock bar which is inserted through a notch in the bottom panel section after the housing has been assembled. Adhesive or frictional interengagement may also be used to secure together the flanges of the panel sections. An internal framework comprising a single, wide loop frame member with spaced-apart ribs is also disclosed.

Glenn A. Kaufman - Kenosha WI

Assignee:

Snap-on Tools Corporation - Kenosha WI

International Classification:

G01M 1500

US Classification:

73119A

Abstract:

An engine timing apparatus includes a piezoelectric transducer and a device for mechanically coupling it to a fuel injector body of the engine. A 6-inch clamping-type pliers is clamped to the injector body. A metal housing is fastened to the pliers at the jaw pivot, the housing having a cylindrical side wall and a circular bottom wall in positive contact with the pliers. The transducer is supported in a recess in a rubber sleeve in the housing and cooperates with the housing to define a resonant chamber at substantially 40 Khz. The dimensions of the pliers are such that the ultrasonic acoustic emissions of the injector body induce in the pliers a standing wave at substantially 40 Khz or a harmonic thereof, the jaw pivot being disposed substantially at an antinode, or point of maximum displacement, of the standing wave. The housing above the transducer is filled with an acoustically insulating foam and covered with a plastic cap.

International Classification:

G01H 1300
G01N 2900

US Classification:

73579

Abstract:

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.
