This short-lived planer specialist was in business from late 1867 (and perhaps a bit earlier) until about May of the following year. At that time E. C. Tainter joined the firm and it became Power, Davis & Tainter. See the entry for that firm for more history on this series of companies.

The titular Power is believed to have been Laurence Power, who eventually went out on his own as L. Power & Co. The identity of Davis is not known.

• From ad in 1868-01-25 Scientific American: "WOOD-WORKING MACHINERY of superior quality manufactured corner 15th st. and Pennsylvania avenue, Philadelphia, Pa. Special attention given to building Woodworth Planers from new and improved patterns. POWER & DAVIS." This ad ran for some months. The 1868-09-09 issue has an ad that reads, "WOODWORTH PLANERS. Wood-working machinery generally, manufactured corner 15th and Penn avenue, Phila. POWER & DAVIS."
• The firm of L. Power & Co. claimed "Since 1867". That date presumably comes from the establishment of Power & Davis. Since the earliest ad we have found is the above-mentioned January 1868 ad, an 1867 date for the establishment of Power & Davis seems likely.
• The 1869-05-22 issues of Scientific American carried an ad: "NEW FIRM—Power, Davis & Tainter, 3003 Chestnut street, Philadelphia, Pa., Builders of Woodworking machinery. E. C. Tainter, successor to J. A. Fay & Co., is from this date one of the firm. Special attention given to Woodworth planers. Late Power & Davis, 1505 Penn Avenue, Phila., Pa."
