Updated by Steven Bartley, naming this as the source of information: The American Architect and Building News. Jan 20, 1877 pg 27. Article as it appeared in the *The American Architect and Building News*: The New Organ for Trinity Church, Boston. - The new organ built by Mr. Hilborne L. Roosevelt of New York, for Trinity Church, Boston, stands in an organ-chamber in the church, on one side of the chancel , one set of front pipe being on the chancel and another in the transept. The organist plays in the transept on the same level as the gallery, which is there. The organ may be said to be five stories high. The first is in the basement of the church, and contains the hydraulic engines and lever which supply the compressed air. The second contains two large bellows and regulator (which steadies the wind), also a portion of the pedal organ. The third contains the great and swell organs and the rest of the pedal organ. The fourth contains the choir organ. The fifth contains the echo organ, which is situated over the ceiling of the church, and is connected with the body of the organ by electricity. This device was first used in the Roosevelt organ in Chickering Hall, New York. The Vox Humana was copied from the celebrated one in Freiburg. The construction of the wind chests is novel, each pipe having a separate valve which is controlled to a great extent by compressed air in place of mechanical action. This facilitates the voicing and tuning and avoids any striking or "cyphering". The combinations on the pedals can be changed at any time, as the organist can set from one stop to full organ on any pedal. The reeds and mixtures of the great organ are placed in the swell box, thereby greatly adding to the crescendo effects. The greatest feature in the instrument is the voicing, and upon this depends it main success. Mr. Roosevelt has aimed at combining in this organ the English Diapasons, the German flutes, and gambas, the French reed, and some of the effects produced in Swell organs. The wind chests of the pedal organ are the invention of Mr. Thomas Winans of Baltimore. Thomas Winans was a Baltimore inventor and engineer, having made his fortune designing and building rail roads with his father, most notably for the Russians. He invented several pipe organ related action devices, and had more than two organs, some of his design in his houses in Baltimore and Newport, RI. He worked with A. Pomplitz on a large outdoor organ and with Roosevelt on several organ projects.
