A shaft alignment wherein a pair of substantially identical clamping members are mounted on the shafts which are to be aligned, with each clamping member having a peripheral reading surface which is generally flat. Each clamping member has a support rod adjustably positioned thereon and projecting generally axially in a skewed relationship relative to the axial direction of the shaft. Each support rod mounts a gauge assembly adjustably positioned for cooperation with the flat reading surface on the other clamping member. The clamping members are mounted on the shafts so as to be generally axially aligned, whereupon the skewed relationship of the support rods permits them to be positioned in generally parallel relationship with one another, with the respective gauge assemblies being adjustably positioned to cooperate with the reading surface on the opposed clamping member.

Shaft alignment device

A mechanical seal construction employing a one-piece plastics packing ring of relatively rigid material for creating a sealed relationship between the nonrotatable seal ring and the stuffing box or gland. The packing ring has a main substantially rectangular body portion which defines an inner annular surface of substantial axial extent, which inner surface has a light interference fit with an opposed surface on the nonrotatable seal ring. A thin ringlike rib is integral with and externally surrounds the main body portion and projects radially outwardly therefrom, which rib is disposed in the axially central plane of the main body portion. This rib has the radially outer end or edge surface thereof maintained in a light interference fit with an opposed surrounding surface as defined on the gland or stuffing box. The seal areas are defined adjacent the axial end surfaces of the main body portion, one of which engages an opposed surface on the nonrotatable seal ring, and the other of which engages an opposed surface on either the gland or stuffing box.
