  THE RAHN-LARMON CO.
  Engine, Turret and Gap Lathes.

  This business was established in 1897 by Mr. John Rahn, Jr., as The Rahn Lathe Company, afterwards being incorporated as The Rahn-Carpenter Company. Upon Mr. Carpenter's retirement, Mr. Arthur J. Larmon entered actively into the business, assuming the duties of Secretary and Treasurer, with Mr. John Rahn, Jr., as President and General Manager.

  The business of manufacturing Engine, Turret and Gap Lathes was started in a very small and modest way at 216 West Pearl street, in a room 20 ft. x 80 ft. dimensions, and at a time when there was a serious business depression, with a small capital and original force of five men, and an output of about two lathes a month. With steady and determined application the business grew until today about one hundred and seventy-five men are employed with an output of about three lathes per day, and a market established in all civilized communities, both here and abroad.
