Austin Combination-Action and Control-System History

Austin Organs, Inc.’s own console page is the source for the present-day answer, and it is a marketing description rather than a specification. It names fully solid-state control, data cabling by CAT-5 or fiber optic, MIDI compatibility allowing the addition of digital voices, and the usual accessory set of transposer, piston sequencer, record and playback, and multiple memory levels. It names no supplier. That silence matters: the general description does not say whether the control is built in house, bought in, or specified project by project, and the page carries no date or copyright year, so nothing on the page itself fixes how current the description is.

Named suppliers appear only in project reports. In its Christmas 2012 newsletter Austin Organs, Inc. reported a solid-state multiplexed control system by Solid State Organ Systems at Old Saint Mary’s Church, Cincinnati, and a control system by Virtuoso at Trinity College, Hartford, two different third-party suppliers in the same season. A Diapason cover feature of May 31, 2013 on Opus 2795 at First Baptist Church, Washington, D.C. describes a Virtuoso system custom-designed in collaboration with Austin vice-president Raymond Albright, connecting the console to the chamber by fiber-optic cable and offering a virtually unlimited number of memory levels for the combination action. The newsletter does not say why one supplier was chosen over the other, and neither report says which system is used in current production.

The Virtuoso maker’s name is printed three different ways. The 2013 Diapason feature gives Atlanta-based International Organ Technologies; an Associated Pipe Organ Builders of America member listing, last modified September 2023, gives Integrated Organ Technologies, Inc. of Alpharetta, Georgia; and the supplier’s own product page, read September 1, 2026, styles the firm IOTI, Integrated Organ Technology, Inc. Each name is reported as its own source prints it, and none of the three is a correction of the others.

Across the Austin Organ Company’s patented combination actions from 1913 to 1935 the mechanism lives in the console stop action. The combination action acts on traces that carry actuators; the actuators engage the rollers of the stop action; and the traces are moved from console pistons and, in the 1935 design, from a foot pedal as well. There is no separate remote combination machine in these designs. The one exception in the series is the electrical design of 1913, which stores its combinations on a perforated carrier sheet rather than on trace actuators. No single patent states this; it is what the descriptions have in common, and it says where the mechanism sat on paper, not where it sat in any built instrument.

Austin’s chest literature is plentiful and its console-control literature is thin, and the two must not be used to fill each other’s gaps. The brochure for the Austin Universal Air Chest describes 12-volt DC console contacts energizing chest magnets, with steel discs acting as air valves. That is chest-side action evidence. It says nothing about console relays, switching, or how combinations are stored and recalled, and a description of the chest magnets cannot be read as evidence about the combination architecture.

The console stop action itself is a solenoid arrangement in current replacement parts. Austin Organs, Inc.’s 2012 product catalog states that its drawknobs insert into electric solenoid actions, and it distinguishes mechanical stopkeys, whose tabs are riveted to a brass hinge plate, from electric stopkeys “drilled and milled to fit Peterson or Syndyne SAMs.” Replacement Austin stop controls are therefore supplied for both a mechanical and a third-party solenoid stop-action world. The catalog is dated 2012, describes replacement parts, and does not say which Austin instruments carry which arrangement or from what date.

The series opens with two patents granted on the same day, November 11, 1913, both assigned to the Austin Organ Company, and they take opposite approaches. US Patent 1,078,078, filed November 14, 1912 and granted to John T. Austin, is entirely electric. Combinations are stored as rows of perforations in a removable sheet of insulating material lying flat against a conducting metal carrier table. An electromagnet-driven pawl and rack advances the table one step at a time; at each step, spring contact fingers project through the perforations to close the circuits of the stop magnets, so each row of holes gives a different registration. Combinations are changed by exchanging or re-punching the sheet, not by setting anything from the console, and the number of rows, and so of combinations, is not stated.

US Patent 1,078,079, filed January 17, 1913, is purely mechanical, and its stated object is to let combinations “be readily and quickly made to conform to the particular music to be played.” The organist depresses the wanted stop keys and pushes a piston. The piston moves a trace horizontally; the trace shifts pivoted actuators, each held in place by a rounded head engaging a cavity in its neighbor, into positions that thereafter move those stop rollers whenever that piston is used.

The mechanical design is the one the later filings build on. US Patent 1,131,814, filed October 30, 1913 and granted March 16, 1915, expressly cross-references “my patent for combination organ stop action, of November 11, 1913, No. 1,078,079,” and adds a two-stage cancel bar to the same trace-and-roller architecture: the bar first energizes a magnet that advances a trace whose actuators return engaged stop rollers to off, then engages all the stop keys directly to move them on. The cross-reference shows the company treating these patents as one developing system. That later patents refer to 1,078,079 rather than to the perforated-sheet design suggests the roller-and-stop-key arrangement was the one carried forward, though the patents do not say so directly.

By 1915 the designs let the player reset combinations at the console. US Patent 1,199,959, filed June 8, 1915 and granted October 3, 1916, claims an actuator adjustable to project from either side of its carrying member or to sit wholly between its edges, a three-position device giving stop-on, stop-off, and neutral. An application filed November 18, 1915 describes a combination made by moving in a plunger and then depressing the necessary keys, “the combinations being settable at will,” with the plungers advanced electromagnetically and a pawl and rack giving step-by-step movement. Settable at will means player adjustment. It does not mean the later capture principle in which the action reads the stop positions electrically, and it does not date any instrument: the instrument record and the patent record are different kinds of evidence, and neither dates the other.

Through the 1920s the trace drive became electrical. The combination action patented between 1920 and 1923 uses a two-magnet arrangement: a button switch closes a circuit energizing both a solenoid and an electromagnet, the electromagnet tilts a cylindrical armature seated in a notch on the trace, the solenoid draws forward an impeller rod whose angular operating piece then advances that trace, and springs return everything when the circuit opens. The stop action of US Patent 1,640,307, filed February 3, 1925 and granted August 23, 1927, pairs primary and secondary follower traces with independent movement and their own operating magnets, so that successive positions of a single piston can operate different divisions such as pedal, great, and choir without extra controls or space. An organist would experience that as a multi-touch piston; the patent does not use the term.

The densest year is 1932, when the company filed at least four combination or stop-action inventions: US 1,899,381 by Basil G. Austin on April 9, US 1,901,622 and US 1,901,623 on May 7, and US 1,905,880 on May 20, all granted in 1933. US Patent 1,901,622, assigned to the Austin Organ Company of Hartford, Connecticut, names the problem it solves: earlier combination systems required the organist to hold a piston depressed for several seconds while the stop-pulling action completed. It claims “means for automatically continuing the operation of said actuating means initially started by said manually controlled means after the latter has been released,” including a pneumatic that keeps the solenoid energized, so that it is “only necessary for the organist to momentarily actuate the piston and then release it.” That framing is the company’s own; it is not independent evidence that earlier Austin actions failed in that way.

US Patent 1,905,880, granted April 25, 1933, gives the organist a selective pedal coupling, so that “the pedal stop actions may, at will, either be associated with the combination stop actions of the manual or may be entirely divorced from the manual stop actions.” A trace bar carries a permanently effective set of actuators for the manual stops and a loosely pivoted, normally ineffective set for the pedal stops; a locking bar with U-shaped spring members, thrown by a lever cam, decides whether the pedal actuators respond. The coupling itself is purely mechanical. The patent headings also record a change of corporate domicile mid-series: filings from 1905 to 1916 name the assignee as Austin Organ Company, “a corporation of Maine,” while filings from 1925 to 1935 name The Austin Organ Company, “a corporation of Connecticut.” None of them gives the year of reincorporation.

The latest combination-related patent indexed to the Austin Organ Company is US 2,021,126, filed January 15, 1935 and granted November 19, 1935, an improved trace arrangement “characterized by the convenience and readiness with which the actuators of the traces may be set to record any desired combination.” Setting uses two controls. A foot pedal energizes a solenoid and rock shaft that withdraws a locking bar; the organist then pushes a thumb piston to advance the trace so that the actuators take up the roller positions, held for the moment by slight friction between cams and studs; releasing the pedal lets a spring re-engage the locking bar, which locks the actuators positively for playing. The stored registration is held by friction and a lock, physical means rather than a stored charge, and that retention belongs to this design and should not be generalized to mechanical combination actions at large.

The filing date matters as much as the mechanism. Austin Organs, Inc.’s own history records that the Austin Organ Company ceased organ production by 1935 and that the successor company officially became successors to it in 1937, so this patent was filed in the year production stopped, and it is uncertain how many instruments, if any, received it. It is the latest Austin-assigned stop-action patent in those indexes, and it does not close the period from 1935 to solid state.

Instrument-level records put the patents in the player’s hands, one instrument at a time. For Opus 22 of 1898 in Hartford, a 1998 centennial program quoted in the Organ Historical Society’s Pipe Organ Database lists “adjustable combination pistons” among the Austin firsts embodied in the instrument, and the database console record codes its combination action as “‘Hold and Set’ Pneumatic/Mechanical” and its control system as “Austin mechanical.” The firsts claim comes from a celebration program rather than a factory record, and the console fields are contributed by database editors.

For Opus 337 of 1905 at First Universalist Church, Riverside, California, the practitioner Robert Scarborough recorded three all-mechanical combination pistons, serving as generals, set in the swell keyjamb and operated by wood dowels, which would work only if the humidity was right. He was recalling an instrument he played in the 1960s, in a database note of 2014. The database codes that console as “Fixed Mechanical” and the 1928 Opus 1650 console as “Hold and Set” Pneumatic/Mechanical, with the separate control-system field reading “Unknown or N/A” on both. A tertiary encyclopedia account of Opus 252 of 1910 at the Hotel Astor adds that the main console contained an early form of combination pistons and that three four-manual consoles could each control both organs, two of them movable.

The manufacturer’s timeline gives dates without mechanisms: an all-electric console developed in 1905, the modern Austin console designed in 1913, console refinements in 1919, with chest refinements listed separately in 1921 and 1932. Each entry is a single line with no source and no opus range. The silence on combination action is a feature of the timeline, not evidence that Austin consoles lacked one, and these dates cannot fix the console of a particular instrument without inspection.

A practitioner account describes Austin organs as using a “tripper” combination action, in which combinations were stored by positioning the stops while holding the desired piston in, with no separate setter interface, and calls the method rudimentary but fairly reliable. That account is a single, unattributed forum post with no date range, and nothing in the manufacturer’s material corroborates it: as of September 2, 2026, Austin Organs, Inc.’s history page presents the Austin Universal Air Chest as the firm’s signature invention and describes neither its combination action nor any piston-held setting method. A short corporate history would not be expected to, so the silence is weak evidence either way.

The method itself is well documented; the Austin attribution is not. An Organ Historical Society console overview by James H. Cook (1998) describes adjustable setting in three classes, holding the desired piston while the stops are set, using a separate setter piston, and using switch or setter boards, and notes that non-adjustable preset pistons were common in the early twentieth century; it names no builder for any method. The hold-the-piston class also appears in a granted United States patent of the 1920s, US 1,664,053 of 1928, but under Edmond Verlinden of Milwaukee as an individual inventor with no corporate assignee. The Austin patents themselves describe other sequences: stops first and then the piston in 1913, plunger first and then the keys in 1915, pedal and then piston in 1935.

The control system in an Austin organ today usually dates to a project, and the documented projects say so directly. In 2008 Austin Organs, Inc. reported fitting the Solid State Organ Systems MultiSystem to Opus 2352, a 1961 instrument at Kansas State University, and to Opus 2442-R, a 1965 instrument at Highland Presbyterian Church, Louisville, each with MIDI and a 100-level combination action. At St. Paul Church, Lansing, Michigan, the 1949 Opus 2169 had its keyboards, stop controls, pedalboard, toe studs, music rack, and combination action all replaced in a console rebuild, with a new MultiSystem giving 100 memory levels. These are three projects from one newsletter; they show what was done, not what the original combination actions were or what is done generally.

Other instruments carry the same pattern from other sources. The Curtis Organ, Austin Organ Company Opus 1416 of 1926 in Irvine Auditorium at the University of Pennsylvania, received a customized MIDI interface in the late 1980s or early 1990s and, in a complete mechanical restoration by Austin in 2002, a new console and relay system. A tertiary listing for Opus 2180, built in 1952 for Third Presbyterian Church, Rochester, New York, records a multi-level SSL combination action with piston sequencer, 40 generals per level plus five divisionals per division, without saying when it was installed. And a congregation’s project page for Opus 1515 of 1929, described as in completely original condition including the console, records that Austin is retaining the original console, making it movable, and fitting it with solid-state combination action, with installation expected in early 2026. That page describes work in progress rather than a completed installation.

An installed control system dates to its project, not to the builder’s name or the instrument’s year. Within the cited project set, every named control system on an Austin instrument is documented as later retrofit work rather than original equipment, and the 1952 instrument above carries a modern combination action with no stated installation date at all. The sample is bounded; it supports the dating rule, not a claim about how often Austin consoles have been re-equipped. Console traffic runs in both directions as well: a tertiary listing records a 2004 Rogers console on Opus 1267, a 1983 Schantz console on Opus 1019, and a 2002 Allen addition on Opus 2616, so neither an Austin nameplate on a console nor a third-party system inside one establishes what the instrument left the factory with.

The patent series is continuous in kind from 1912 to 1935, carrier, trace, roller, and actuator mechanisms operated electrically and pneumatically, and it contains no patent for an electronic or memory-based capture system. Google Patents indexes about fifty patents under Austin Organ Company, the latest granted March 9, 1937, and none at all under Austin Organs, Inc., so no patent is indexed to the successor firm after the 1937 reorganization. So the patent route documents the mechanical and early electric era and contributes nothing to the period from the late 1930s to solid state. That endpoint belongs to the index rather than to the company: the index’s own filing-date range runs on into 1935 to 1938, and a patent can sit under an individual inventor’s name or under an unindexed spelling of the assignee. The patent record dates designs; it does not date the control system in any particular instrument today.

The successor firm’s publications add claims but not a chronology. In a 2007 Diapason cover feature, Austin president Michael Brian Fazio stated that more than four dozen patents had been granted to the company over the years, enumerating none beyond reed-pipe construction, and the firm’s console page states that over 50 patents have been applied to Austin console components and that an Austin console guided the American Guild of Organists in 1932 in developing its console-dimension standard. The 2007 feature names individual consoles by date, a five-manual drawknob console of 2000 for Opus 323, a black lacquer drawknob console of 1963 for Opus 500, and a mahogany four-manual console completed in about 2006, but identifies none of them as a pneumatic setterboard, capture, early electronic, or solid-state system and offers no sequence of combination-action generations. That is what one article shows, read September 2, 2026; the journal’s new-organ listings from 1950 to 1990 are not searchable, so a chronology may still sit in print without being findable.

Three things, then, are documented: the patented designs of the Austin Organ Company to 1935, the solid-state consoles Austin Organs, Inc. describes today, and a set of named projects in which third-party systems were fitted to Austin instruments. Between the first and the second, the builder-side sources named on this page are silent, and that silence is not proof that no record exists. For a particular console, the answer to which generation stands in it comes from inspecting that console and reading its project documents, not from the name on the nameplate or the year on the opus list.
