Abstract
A spline coupling positionable within a gear housing for coupling a flyer to the spindle gear of a spindle has an integrally attached spindle washer for effecting a seal about the spline coupling and spindle gears. The spindle washer is attached to an uppermost portion of the spline coupling and serves to prevent oil, water and lint from reaching both the spindle gear and the base of a bobbin positionable over the spindle.
Claims8
A spline coupling and spindle washer device for roving frames, said device comprising:
- a spindle gear having gear teeth and mounted for rotation with a spindle;
- spline coupling means having gear teeth for engaging the gear teeth of said spindle gear associated with said spindle, the spline coupling means coupled to rotate a flyer and thereby to effect a driving connection between said spindle gear and said flyer;
- and
- spindle washer means positioned within a gear housing and being of unitary construction with said spline coupling means and being concavely upwardly sloped, said spindle washer means thus constructed and arranged for serving to prevent oil contamination of yarn on a bobbin positioned over said spindle and to prevent water and lint contamination in an area of engagement between said spindle gear and said spline coupling means.
In combination with a spindle, spindle gear, and flyer on a roving frame, a spline coupling meshing with the spindle gear and coupled to the flyer to provide a driving connection between said spindle gear and said flyer;
- a spindle washer positioned above the spindle gear and being of unitary construction with said spline coupling, the spindle washer having an inner edge closely surrounding the spindle below a bobbin on the spindle to prevent oil contamination of yarn on the bobbin positioned over said spindle and to prevent water and lint contamination in an area of engagement between said spindle gear and said spline coupling.
