Abstract

A work stand for rotably mounting an engine thereon during the initial construction of the engine, or for repair of the engine, includes two concentric rings which are disposed in upstanding relationship and are mounted on a base. The inner ring is rotably mounted within the outer ring and includes a plurality of axially extending arms which engage the engine. The latter is mounted in a generally horizontal disposition and is rotable with the inner ring whereby access to the engine is unobstructed from either the top or bottom of the engine, as well as along the entire length of the engine. A locking mechanism is provided between the inner and outer rings of the work stand for maintaining the engine at the desired angular attitude, and the engine is mounted such that its center of gravity is disposed adjacent the upstanding planes of the concentric rings.

Dependent claims

A build stand for rotatably mounting an engine thereon comprising:

a base;
an outer structural ring fixed to and supported by the base, in a substantially vertical plane, said ring being constructed of a rolled channel member, having a U-shaped cross section including base portion and arm portions;
bearing means secured to the outer ring and disposed on the radially inward surface of said outer ring;
an inner structural ring concentrically mounted within the outer ring for rotation on said bearings, said ring being constructed of a rolled channel member having a U-shaped cross section including a base portion and arm portions, said base portion positioned radially inward of said arm portion;
a plurality of axially extending support arms fixed to said inner ring and having means to receive and secure the engine in a generally horizontal disposition such that its longitudinal axis is generally aligned with the longitudinal axis of the concentric rings, and the center of gravity of the engine is disposed substantially within the plane of said rings.
