"Vintage Machinery" entry for E. & B. Holmes
The nature of our invention consists in the combination of a guide-rest with a cutter-head carrying chamfering, croziug, and howeling cutters in such manner that the action of said cutters will be gauged from the exterior surface of the cask, and thereby a true and uniform chamfer, croze, and bowel obtained.

What we claim as our invention, and desire to secure by Letters Patent, is;.

The combination of the cutter-head H, supported by the swinging frame I, with the rest J, supported by the swinging frame K, oscillating upon a common axis with the cutter frame, when said frames K and I are provided with a locking mechanism by which the cutter-head may be held at a definite distance from the rest, and thereby made to follow the curvature of the cask, substantially in the manner and for the purpose set forth.
