ORGAN.

SPECIFICATION forming part of Letters Patent No. 570,200, dated October 27, 1896.

Application led December 31,1894. Renewed September 2,1896. Serial No. 604,674. (No model.)

To all whom/ t may concern: tions. The levers D near their roar ends are Be it known that I, JOSEPH H. CHASE, of guided by pins d2. the city of Meriden, county of New Haven, E designates the manual-keys. They may and State of Connecticut, have invented cerbe supported in the usual manner. On their 5 tain newand useful Improvements in Organs, under sides they are provided with projecof which the following is a specification. tions e, that coact with regulating-screws d3,

The pneumatic motors AG communicate 45 At their upper ends they impinge against leinternally with the wind-chest E under convers D. These levers D are fulcrumed at trol of valves A7. The valves A7 are shown v y their forward ends by pins d to brackets d. as pivoted at one end to pins a9 and guided i Springs B4, arranged within the chambers B2, near the other end by pins am.

Hence with each valve A7 there must be combined a valve AS. As here shown, the valves AS are connected by screws a with the valves AT, so that when a valve AT is opened the correspending` valve AS will be closed, and vice versa. XVhen one of the valves A7 is closed and the corresponding valve AS opened, the corresponding pneumatic motor A will be in communication with the atmosphere, and hence will be expanded. Vhen the position of the valves is reversed, communication will be established between the corresponding pneumatic motor and the wind-chest F. This will result in the collapsing' of said pneumatic motor and cause the speaking of the corresponding sound-producing` devices oi' the set A.

The valves A7 AS are controlled by pneumatic motors G, located within the windchest F. These pneumatic motors communicate with tubes or ducts G and the latter communicate with tubes or ducts G2 G3 G1. Preferably the ducts G' G4 will be made of iiexible rubber tubes. The ducts G'l communicate with ducts G5 in a block G, the ducts G5 being' controlled by valves G7, arranged upon levers GS, which are fulcrumed by pins g to brackets g', affixed to the forward side of the block GG. The block G is pivoted upon a pin or pins g2, and hence is free to rock.

Of course it will be understood that there is a duct G', a duet G2, a duct G3, and a duct G'l for each note that is to be produced by the sound-producing devices A.

The block GG is rocked into one or other of its extreme positions by the hand of the player operating, preferably through a lever or arm. rlhe levers Gsare held in a position to keep the valves G*` closed by means of springs gt, iitted in the block G.

lVhenever it is desired to play the soundproducing devices A by means of the manualkeys the block G is rocked into such position that the levers D may operate the levers GS to open the valves G7. Preferably the levers D will be provided with regulating-screws (Z5 at the ends where they are adapted to coact with the levers GS.

It will of course be understood that when the valve GT is opened the corresponding pneumatic motor G will be expanded and the corresponding` pneumatic motor AG will be collapsed, so as to cause the speaking of corresponding sound-producing devices A.

I will now turn to the means for playing' the instrument mechanically. The ducts G2 communicate with ducts H' in a tracker-board ll'. Over the open ends of the ducts II a perforated music-sheetImoves, as usual. Vhen playing` is to be done manually only, a cover J is moved over the open ends of the ducts il in the tracker-board H. rlhe cover J may be made of two side pieces j', fastened together by rods ff jl f5. Vithin the frame thus formed a pad of leather or similar material is made by taking a strip and forming it into a belt extending around the rods tjl The rod jg is at the end pivo tally connected to a cross-rodj. ArmsjS are pivotally connected to the latter. These armsjS extend across the sides of the tracker-board. rlhey are affixed to the rock-shaft j, which is journaled in the cheek-pieces at the sides of the tracker-board. A crank-arm jim, aliixed to the rock-shaft j, serves to oscillate the latter, and hence to slide the cover J, which normally rests upon the upper side of the tracker-board. lVhen pushed forward, it may move the music-sheet away from the end of the tracker-board and then drop down over the end of the trackerboard, so that its pad will close thc ends of the ducts IT. The music-sheet may be rewound while the cover is in' place at the end of the tracker-board. The reverse movement of the rock-shaft jfl will shift the cover to a position above the tracker-board, thus opening the ducts ll. The arm jm of rockshaft j maybe connected to the means which are employed for reversing the music-sheet, so that the cover will always close the ducts Il', except when the music-sheet is driven in the direction to play a tune.

It will be obvious that while the manualkeys E are not being used the valves GT will close the ducts G5 and keep them closed. If during such time air is admitted through perforations in the music-sheet to the ducts G3, the pneumatic motors G' will be operated in the. manner and with the result before dcscribed while explaining' the operation of the manual-keys.

The sound-producing devices S of the solo or subbass set are controlled by valves S, arranged in a chest S"3 and operated by pneumatic motors S3, which communicate with duets S, that are controlled by the valves A7 A8. Of course there willbe a valve S', pneumatic motor S3, and a duct S'l for each soundproducing device in the solo or subbass set.

The sound-producing devices of the subbass are indicated as being reeds, and the reed-cells communicate with a wind-chest S, leading' to the exhaust-bellows.

The chamber S2 communicates with the atmosphere under control of a valve SG, which is operated in any suitable manner, as, for instance, by an ordinary stop-rod. Only when this valve S is opened can the sound-producing devices of the subbass speak.

Obviously this instrument may be played not only manually or mechanically, but both manually and mechanically at the same time.

That I claim as my invention, and desire to secure by Letters Patent, is

1. In a mechanical musical instrument, the combination of sound-producing` devices, a tracker-board comprised in mechanism for controlling` said sound-producing devices, a music-sheet for traveling over the end oi' the tracker-board, mechanism for rewinding the music-sheet after playing, and a cover or stop for said tracker-board operated by said rc- IOO IIO

Winding mechanism independently of the music-sheet, substantially as specified.

2. In a mechanical musical instrument, the combination of sound-producing devices, a tracker-board comprised in mechanism for controlling said sound-producing devices, a music-sheet for traveling over the end of the tracker-board, means for propelling the music-sheet, in one direction for playing, and in another direction for reWinding, and a cover or stop shifted at the commencement of the rewinding of the music-sheet to close or stop air-ducts of the said tracker-board, the said cover or stop being constructed to slide adjacent to one side of the tracker-board and to drop over the end of the tracker-board, substantially as specified.

In an organ, the combination of manualkeys, sound-producing devices controlled by said keys, an independent set of sound-producing devices, valves for controlling the independent set of sound-producing devices, and a rocking bar provided with valve-seats and supporting the Valves for the independent set of sound-producing devices, substantially as described, whereby the independent set of sound-producing devices may be put out of or under control of the said keys.

In an organ, the combination of manualkeys, sound-producing devices controlled by .said keys, an independent set of sound-producing devices, valves for controlling the independent set of sound-producing devices, a rocking bar provided with valve-seats and supporting the valves for the independent set of sound-producing devices, substantially as described, and adjustable ducts leading from the valve-seats, and, by their adjustability, permitting the movement of the said rocking bar.

5. In an organ, the combination oi' manualkeys, sound-producing devices controlled by said keys, an independent set of sound-producing devices, valves for controlling the independent set of sound-producing devices, a rocking bar provided with valve-seats, and iieXible tubes communicating with the valveseats and extending from said rocking bar, substantially as specied.

6. In an organ the combination with a tracker-board and a cover comprising a frame resting upon one side of the tracker-board, rods for shifting said frame, arms for shiftin g said rods and their rock-shaft carrying the said arms, substantially as specified.
