SPECIFICATION forming part of Letters Patent No. 304,576, dated September 2, 1884.

Application filed October 3, 1883. (No model.)

To all whom it may concern/.-

Be it known that I, JOHN W. STEERE, a

citizen of the United States, residing at Springfield, in the county of Harnpden and State of 5 Massachusetts, have invented new and useful.

Improvements in Pipe-Organs, of which the following is a specification.

This invention relates to improvements in churchorgans; and it consists in a novel arrangement of the pipes thereof, whereby a portion of the great-organ pipes are located in the swell-box and supplied with wind from the swell-chest, and in an improved auxiliary key-action, whereby said pipes or great-organ stops, which are located on the swell-chest, are played by the great-organ manuals, the object being to produce a modified effect from certain great-organ stops, and to provide for playing them by the great-organ manuals independently of those belonging to the swellorgan.

The drawing forming part of this specification is a side elevation, partly in section, of such parts of a church-organ as illustrate the above-nanied improvements embodying my invention.

In the drawing, A indicates parts of the frame of an organ. 6 isone of the swe1l-organ manuals, and 'v is one of the greatorgan manuals. b is the wind-chest of the great organ, and c is the swell-organ wind-chest. h is a part of the swell-box, partly broken away to show pipes withinit. a is one of the pipes of the great organ, located in the swell. 0 is one of the swell-organ pipes. 3 indicates the line of action-connections from the great-organ manual 2) to the wind-chest b. m is a pipe on the latter. 2 indicates the line of the actionconnections from the swell-manual e to the swell wind-chest c. n is a block secured on one of the vertical trackers of the great-organ action-connections 8. 5 6 7 8 9 1O 11 12 indicate the parts of the auxiliary action connecting the great-organ manuals with the swell wind-chest 0.

Certain ones of the stops of pipes usually located on the great-organ wind-chestsuch as the trumpet and other stops of similar character-are found to have their quality of tone much improved by locating them within the swell-box of the organ, instead of, as is usually done, placing them in the open and exposed position which they occupy on the great-organ wind-chest; and my improvements provide for so locating said stops in the swell and for playing them by the great-organ manuals, by interposing an auxiliary action-connection between the great-organ manuals and the swell wind-chest, as hereinafter described.

The action-connections 2, leading from the swell-manual e to the swell wind-chest 0, are of the usual description, as also are those designated by 3, leading from the manual 0 to the great-organ wind-chest 1), except that the lastnamed connections are provided with means whereby their movements are communicated to the below-described auxiliary swell-chest connections To communicate the action of the manual 2) to the swell-chest independent, of the regular swell-action, the action-connections, denoted by figures 5 to 12, inclusive, which constitute the aforesaid auxiliary action, are interposed between the action of the great organ and the wind-chest 0. When the manual 1) is pressed down, acting as ordinary keys do, the vertical tracker 3 moves downward to open the valve in the wind-chest b. A block, n, is secured on said tracker 3, and the latter is carried through a slot in the horizontal arm of the bell-crank lever 5, so that when said tracker moves downward said lever is given a vibratory motion. The connection of said lever 5 with the wind-chest c by means of the bellcrank levers 7, 9, and 11, and the trackers 6, 8, 10, and 12, and with the tracker 3 of the great-organ action, enables the player to utilize the great-organ stops in the swell by means of the manual 1; without the intervention of any other mechanism, and said auxiliary connections are no inconvenience in playing the great organ in the usual manner.

\Vhat I claim as my invention is 1. In a pipe-organ, the swell-chest provided with its swell key-action, the great wind-chest provided with its great key-action, as described, the latter having its tracker 3 provided with a stop, a, affixed thereto, in combination with a slotted bell-crank lever, 5, through which the tracker 3 passes, and its auxiliary action for connection with a greatorga-n pipe in the swell wind-chest, all operat ing substantially as described.

2. The swell wind-chest and its swell-organ pipes 0, in combination with one or more greatorgan pipes located in the swell-chest,

a swell-organ key-action, and an auxiliary great key-action connecting the great pipe in IO the swell with the key-action of the great 01'- 'an.
