Abstract

29,296. Gadelha, J. da C. March 28, [Convention date]. Cutting-appliances.-A hatchet-like implement for tapping rubber and like trees comprises two symmetrical converging blades 2, 3, pivotally mounted in the recesses 4, 5 of the head or stock 1. The blades are pressed apart by a spring 18, the movement being limited by the edges 8<1> of the recesses 8 and the edges 14, 15 of the plate 16. The blades approach each other as they penetrate the bark, and a wedge-shaped incision is produced, the depth of which depends on the normal distance between the blades.
