Abstract
Two spaced support members support a shaft horizontal in partial lower bearing journal surfaces. A retractable pin is positioned above the shaft at each support member to retain the shaft in the journal surfaces. A shelf at each journal surface in front of the pins provides for loading and unloading of the shaft. A flat locking surface fixed to rotate with the shaft and a mating engagable locking member prevent rotation of the shaft.
Claims15
A shaft restraining device comprising
- two spaced support members each having a substantially horizontal journal surface for rotatably supporting the shaft on a lower surface thereof,
- a retractable pin positioned extending over the shaft at each support member to restrain removal of the shaft from each of said journal surface, and
- a shelf on each of said support members extending from said journal surfaces in front of each of said retractable pins.
A shaft rotational locking device comprising
- a member for rotatably supporting the shaft,
- a flat locking surface rotationally associated with the shaft, said flat locking surface substantially parallel to a tangent to the shaft, and
- a locking member for engagement with said locking surface to prevent rotation of the shaft, said locking surface being rotatable with said shaft, and said locking member extending adjacent said flat locking surface to engage said flat locking surface to prevent the shaft from rotating.
A shaft restraining device comprising
- two spaced support members each having a substantially horizontal journal surface for rotatably supporting the shaft on a lower surface thereof,
- a retractable pin positioned to extend over the shaft at each support member to restrain removal of the shaft from each of said journal surface, and
- a shelf on each of said support members extending from said journal surfaces in front of each of said retractable pins, the pin having a surface for engaging the shaft, said surface being normally spaced apart from the shaft during shaft rotation.
A shaft restraining device comprising
- two spaced support members each having a substantially horizontal journal surface for rotatably supporting the shaft on a lower surface thereof,
- a retractable pin positioned to extend over the shaft at each support member to retrain removal of the shaft from each of said journal surface, the pin having a surface for restrainingly engaging the shaft, said surface being spaced apart from the shaft during normal shaft rotation,
- a shelf on each of said support members extending from said journal surfaces in front of each of said retractable pins, said shelf being spaced below a lower surface of said retractable pin to permit lateral sliding of the shaft on said shelf, said retractable pin being retractable sufficient for entry of said shaft into said journal surface,
- a flat locking surface fixed for rotation with the shaft, said surface being substantially parallel to a tangent to the shaft, and
- a locking member for engaging said flat locking surface to prevent rotation of the shaft.
