Abstract: A laminated ratchet tool includes a laminated ratchet head defining an internal gear and a pawl mechanism carried by the ratchet head and including two laminated pawls arranged for ratcheting engagement with the gear teeth. Each of the laminated parts includes a plurality of plates arranged in a congruent stack and fixedly secured together, as by brazing. Each plate is formed by stamping and has plural orienting structures stamped therein, each such structure being a displaced portion which forms a recess at one side of the plate and a projection extending from the other side of the plate, so that the projections on one plate mate in the recesses of an adjacent plate to facilitate alignment of the plates. The ratchet head includes toothed inner plates which define the internal gear and untoothed outer plates which define bearing surfaces for the pawl mechanism.

Abstract: A cordless electric device has a main body portion extending along an axis and a handle portion extending at an obtuse angle with respect to the axis, the handle portion receiving therein along a second axis a battery pack. The device has a two-part housing, with the parts respectively defining the front and rear of the body and handle portions.

Abstract: An optical toe/track measurement system includes a pair of toe gauge assemblies respectively mountable on the two wheels at one end of a motor vehicle and a pair of track scale assemblies respectively mountable on the other two wheels of the vehicle. Each toe gauge assembly includes an elongated tubular housing having toe and track projection systems for respectively projecting toe and track light beams from the opposite ends of the housing, the track beam being projected coaxially with the housing onto the track scale on the same side of the vehicle, while the toe beam is projected perpendicular to the longitudinal axis of the housing onto a scale carried by the toe gauge assembly on the other side of the vehicle. Light is supplied respectively to the two toe gauge assemblies throught two fiber optic cables from a single remote light source.

Abstract: An over-center latch mechanism having a spring loaded link including a projecting rod. The rod having an "S" shaped bend on its free end which permits insertion and removal of said bend from an elongate slot only by actuation of the lever in the over-center mechanism.
