ABSTRACT:
In the business of supplying bushings as tool guides for machine operations a minimum of two types of bushings need to be stocked. One type is a headless press fit sleeve. The other type is a slip fit sleeve with a head at one end. The headed slip fit type is desirable but greatly more costly. Such a great number of different sizes need to to stocked by the supplier that the cost of maintaining two complete inventories, one of each type, often becomes prohibitively expensive. The invention here involved makes use of only one complete inventory of bushings of the less costly and simpler press fit type and a partial inventory of separate heads which can be fitted on the press fit sleeve, modified to only a minor degree, and in this way to supply an order for the normally more costly headed slip fit bushing.
