First Claim
Patent Images
1. An improved pulley alignment tool useful for three dimensional axial alignment of the rotational axis of a wide driven pulley connected to a device to be powered, with the rotational axis of a driving pulley connected to a prime mover, including:
- a first bar having a first driving pulley engaging pad mounted on one end of the first bar and a second driving pulley engaging pad mounted on the other end of the first bar, the engaging pads being adapted to contact one face of the driving pulley, a first pulley engaging arm juxtaposed the first engaging pad and a second pulley engaging arm juxtaposed the second engaging pad, the pulley engaging arms being individually adjustable so as to pull the pulley engaging pads firmly into contact with the driving pulley face;
a second bar having one end rigidly attached to the first bar and extending perpendicularly from the first bar to form a T-shaped structure, the second bar having a third driving pulley engaging pad mounted at a location between the ends of the second bar, the second bar having a third driving pulley engaging arm juxtaposed the third driving pulley engaging pad, the pulley engaging arm being adjustable so as to pull the third driving pulley engaging pad firmly into contact with the driving pulley face, the three engaging pad faces being coplaner; and
an alignment plate mounted on the end of the second bar distal the first bar, the alignment plate having three locator pins mounted on its surface, the locator pins having coplaner faces defining the plane for locating the surface of the driven pulley, the alignment plate having means to position the driven pulley with respect to the locating pins until the driven pulley is securely fastened.
