Knight's American mechanical dictionary : a description of tools, instruments, machines, processes and engineering, history of inventions, general technological vocabulary ; and digest of mechanical appliances in science and the arts . ng rived lioops to make them tracta-ble in jilacing them around casks. Hoop-rivingMa-chine. {Coop-ering.\ A machine in which the barof wood to be rived is sawed out ofa proper width for the hoop refjuired,and the end checked by a gang ofcircular saws. Tlie end is then placedbetween the guiding friction wheelsand advanced to the groove of thewheel, where it is seized by the biteof the upper pressure disk, and pass-ing along is deflected upwards byanother wheel emerging from be-tween the latter wheel and the- itp-per disk in a riven condition. Hoop-sawing Ma-chine.(Coopering.) a. A niacldne in whichgaged stuff is fed to a gang of cir-cular saws and reduced to dimensionsfor making hoops. In the example,the saw-shaft has journal bearingeither above or below the guiile-roU-ers. The guide-rollers are kept in their journals bypins traversing the upwardly projecting sides of thesaid journals. b. A machine which removes, by .successive ac-tions, a thin strip for the edge of a board. Fig. Hoop-Sawing Machine. c. A machine which saws hoops from a log, whichis rotated between each cut, the thickness of a hoopplus the kerf; Hoop-Riving Machine. the saw cuttingdown into thelog the widthof a hoop, anda second saw ora cutter remov-ing the hoop socut.
