Patent Number Date Title Name City Description
11,625 Aug. 29, 1854 Machine for cutting tenons Charles P. S. Wardwell Lake Village, NH The tenoning machine is intended for making square tenons on bedstead frames, etc.

13,735 Oct. 30, 1855 Machine for cutting double tenons Charles P. S. Wardwell Lake Village, NH
16,814 Mar. 10, 1857 Circular sawing machine Charles P. S. Wardwell Lake Village, NH This double-arbor tablesaw was a big commercial success, and the basic design remained popular for over 100 years until better combination blades made it less advantageous to have two different blades readily available. The Wardwell saw was sold by Wardwell himself from 1857-1863 (based on ads in Scientific American), then by James Goodrich & Co. (1867 ad), L. D. Fay of Worcester (1868-1869 ads in Scientific American), then by Rollstone Machine Works (1872-1883 ads in Manufacturer & Builder).
Wardwell applied for an extension to this patent. It appears that his request was denied.

34,174 Jan. 14, 1862 Improved planing-machine Charles P. S. Wardwell Lake Village, NH This designed was subsequently improved by the inventor in patent 160,372. An example is reported, labeled, 'CPS WARDWELLS PATENT JANUARY 14,1862'. We presume that it was manufactured by the inventor.
In his book "History of the Planing Mill', Charles Tompkins said of this clapboard planer, "The Wardwell machine planed one edge thinner, but it required the lumber to be sawed 5/8 of an inch thick, in order to make siding or clapboards 1/2-inch on the thick edge, and the labor and waste of stuff in planing the other edge down to 1/4 of an inch, was a serious objection to the machine, and probably one reason why it never came into general use, when a board 3/4 or 7/8 of an inch thick, after being planed both sides and both edges, could be sawn in two diagonally, and make two clapboards with only the waste of the saw kerf."
