In 1886 Frank J. Bergquest made a jointer with a patented three-head carriage. One example has surfaced but it appears to be a standard jointer without the patented feature.

  A New Jointer
  In its "Exposition Notes" in its September issue, Wood and Iron, of Minneapolis, Minn, has the following: A wood jointer that is attracting the attention of the wood-workers and others interested in machinery, is to be seen in the space occupied by J. H. Kerrick. Mr. Frank J. Bergquest, the patentee, is a practical mechanic and wood-worker, who has made this business a life-long study, and can readily convince all who are interested that he has produced a machine that possess more points of real merit than any in the market. It is simple in construction and perfect in adjustment. Instead of one head, or cylinder, as other machines are constructed, it has three, so attached to a revolving carriage or cylinder that it can be changed from one to the other almost instantaneously. The great advantage of this is at once apparent, combining, as it does, three machines or tools in one. Each of the three heads is arranged for straight or moulding knives, so that by simply turning the carriage, which is stationary when in operation, any one of the heads can be brought into use. By this arrangement there is a great saving of time and labor. All practical wood-workers who have examined and seen its working pronounce it the best machine of the kind on the market, and say it must soon come into general use, on account of its economy of labor and cost.
