Description: |
| "My invention relates to that class of hoop-machines in which the hoop is cut from the edge of a plank by a reciprocating knife."In the manufacture of this kind of hoops as heretofore practiced the hoop-splint has been cut from the plank in one machine, and the splints have been then passed in turn through a number of other machines, in which the splint was lapped, tapered, and pointed, the process requiring many successive handlings and producing a large percentage of 'culls.'"My invention has for its object the production of a machine in which hoops are cut from the lumber and lapped, tapered, and pointed at one operation by automatic machinery, without the necessity of rehandling, the hoops being delivered from the machine ready to be placed on the barrel, with the exception of planing the outer surface for the purpose of rounding the corners, which may be practiced, if desired; and my invention consists in combining with a reciprocating dividing-knife automatically-operating lapping or tapering and pointing knives, all as hereinafter more fully set forth." |
