This mid-sized maker of mid-sized industrial woodworking machinery was founded by Laurence C. Power of Philadelphia. We are uncertain exactly when the company began; they claimed 1867 but that date may be the date some acquired company was established. The earliest confirmed sighting of the "L. Power & Co." name is 1879. They survived until about 1960.
Some products of L. Power & Co.—probably later ones—were marked simply as "Power".

Laurence C. Power and Colladay Machine Works
By 1919, Mr. Power, who was by that time no longer with the company bearing his name, purchased Jos. O. Colladay Co., Inc., and renamed it Colladay Machine Works. That company survived past 1920, but at some point their production machinery was relocated to York, PA, and became B. M. Root Co., which was eventually acquired by G. M. Diehl Machine Works, Inc.
