Abstract:
My invention relates to shaping-machines, and has for its objects to provide a construction especially adapted to resist strain and prevent springing of the ram and toolhead;
to provide for the quick and accurate adjustment of the shifting mechanism for a short or long stroke of the ram; to render the adjustment of the feeding movement of the table ready and certain while the machine is running, and to generally simplify the construction with a view to making the machine effective and durable and to secure quick and easy action in adjusting the parts. My invention consists in a special arrangement of the ram and its housing, whereby the housing projects over the worktable and holds the ram against springing under the strain of the work in all positions. It consists of a series of gravity-dogs of special form disposed along and carried by the rain and arranged to correspond to the different lengths of strokes and to be thrown into line with the lever connected with the shifting mechanism. The invention also includes the mechanism for driving the feed-table and for limiting the amount of movement of said mechanism to vary the feed.
Claim:
In combination, the ram, the housing extending over the worktable and beyond the inner limit of the rain's movement to positively support the same in its different positions, and the worktable adjustable toward and from the overhanging housing. |
