Abstract
20,483. Rayne, H. Sept. 2. Cutting-appliances.-Relates to a knife for tapping rubber trees and particularly trees yielding Ceara and similar rubber. On the handle A is mounted a cap B which is drilled to receive a pair of clamping-jaws C, D controlled by a set-screw E and holding between them a blade F. The cap is cut away at the ends of the blade as shown at G, Fig. 1, shoulders K being left to ensure that the incisions are perpendicular to the bark of the tree. The blade may be made adjustable in the cap, or blades of different lengths may be provided without means of adjustment. The shoulders of the cap limit the depth of penetration of the knife. The handle A may be mounted as shown on a rod J, which may be of adjustable length in order to reach high parts of a tree. The screw E may be made inaccessible except when a special tool is used.
