Dated and marked A. Klock, this .American follows precisely those detailed in Sheffield pattern books. (Smithso- nian photo 49794-C.) .*^* :%%: this is not a reliable guide, however, since similar moldings are retained throughout the century. Fi- nally, the plane is equipped with a fence controlled by slide-arms, fixed with wedges and not by adjustable screw arms. After 1830, tools of high quality, such as Wiiite's, invariably have the screw arms. The rabbet plane, made by Carpenter, is traceable via another route, the Patent Office records. Carpenter, self-designated "toolmaker of Lancaster," submitted patents for the improvement of wood planes between 1831 and 1849. Examples of Carpenter's work, always stamped as shown in figure 27, survive, both dated and undated. There are several of his planes in the collections of the Bucks County Historical Society, and dated pieces are known in private collections. Iniicrent in the bench planes is a feeling of motion, particularly in the plow and the rabbet where basic design alone conveys the idea that they were meant to move over surfaces. Of the three examples, only the brass tippings and setscrew of the plow plane suggest any enrichment, and of course these were not intended for decoration; in later years, however, box- wo
