Figure 63. — 1870: The metallic version of the plow plane later produced by Stanley and 

 Company was patented by [Charles] G. Miller as a tool readily "convertible into a 

 grooving, rabbeting, or smoothing plane." In production this multipurpose plow gained 

 an elaborate decoration (fig. 51) nowhere suggested in Miller's specification. (Wash 

 drawing from U.S. Patent Office, June 28, 1870, Record Group 241, the National 

 Archives.)
