Abstract: A snubber for interpositioning between a substantially vertical surface on a transporting vehicle and an end member of a transported vehicle carried by the transporting vehicle comprises two elements, viz,: a first element for being secured to said substantially vertical surface on the transporting vehicle, and a second element mounted on the first element for cushioned vertical movements relative thereto, the second element having a substantially vertical surface engageable by the end member of a transported vehicle. Relative vertical movements between the transporting vehicle and the transported vehicle are accompanied by vertical movement of the transported vehicle end member substantially in unison with said second element, thus preventing undue rubbing of the end member on the snubber.

Abstract: This disclosure relates to a device for centering a V-block relative to a tool which is to perform a machining operation on a workpiece to be mounted in the V-block. The center finder is in the form of a block contoured to seat in the V-block and having formed in the upper surface thereof grooves of a width corresponding to various machine tool widths so as to effect the centering of the center finder block relative to the tool which, in turn, automatically centers the V-block relative to the tool.
