This firm patented and sold the Woodbury Air Engine. The engine was manufactured under contract by the Taunton Locomotive Works, Taunton, MA.

      "The inventors, however, are deserving of the greatest credit for perfecting the machine to its present point. They have expended $150,000 in money, and 12 years of time upon their invention, and they deserve to reap good profits from it. They have incorporated a company under the laws of New Hampshire with a capital stock of $1,000,000, and propose as soon as sufficient capital is secured to fill orders for the engine which are already in their hands. The engines are to be made, we are informed, by the Taunton Locomotive Works. The offices of the company, whose official title is “The Woodbury, Merrill, Patten & Woodbury Air Engine Co.,” are at 8 Exchange Place, Boston, and at Nashua, N. H. We acknowledge the courtesies of Messrs. WM. H. Billings, Treasurer of the Taunton Locomotive Works, and Joshua A. Merrill, one of the inventors of the engine, for information received. In an early issue we hope to make some further comments on this new motor and on the chances which it seems to open up for replacing that most wasteful motor, the steam engine, with a more economical prime mover." (Quote from 1889.)
