ABSTRACT:
A linkage controlled spring powered feed system for maintaining a virtually constant force against a linearly movable member such as the feed member of a honing machine or other device, the system including a lever member having one end which bears against the linearly movable member and an opposite end, the lever member being pivotally mounted at a location between the opposite ends thereof on the machine frame, a linkage assembly bearing against the opposite end of the lever member in a direction to apply force against the linearly movable feed member, the linkage assembly including a first expandable link member having a compression spring for exerting force against the lever member and a second link member for adjusting the position where the linkage assembly engages the lever member as the lever member moves about the pivotal support to change the effectiveness of the compression spring in applying force to the linearly movable member. The present system can optionally include an additional linkage enabling selectively adjusting the level of constant force to be applied against the linearly movable member, and one or more cam members and spring members enabling speed control, counteracting and otherwise affecting the force applied against the linearly movable member.
