The Benton Dresser.*—The diamond dresser in P. P. Bentonspatent, No. 222,443, dated December 9, 1879, has a staff-bed, bearing aframe, which forms the ways upon which the carriage works. This frame isfastened at one end by the bolt permitting it to be inclined to the right forfurrowing. At the other end of the frame there is a bolt which passesthrough an eccentric in the bed, the working of which raises and allows the. Fig. 258. frame to cut deeper at the eye, and to adjust the cut of the diamond to thestaffing (Fig. 258). In the Uhlinger patent, No. 182,358, July 26, 1876, the upper surface ofthe end cross piece of the base-plate rise to a common central elevation, uponthe top of which are studs passing through slots in the cross-bars of the bed-plate proper, dividing the bed-plate centrally lengthwise. By grooved slottedstandards and screws the bed-plate is held rigidly at any desired angle. Tohold it perfectly level, there are wedge pieces which may be turned in. Tofurrow, the wedge pieces are turned out, the desired angle given to the bed-plate and the screws tightened. In the McFeely patent, 188,022, March 6, 1877, the carriage is upon aseparate frame having carriage guides. The carriage bed can be tilted toany angle corresponding to the furrow, and tightened by thumb-nuts. Thecarriage will travel crosswise up and down the incline of its bed, accordin
