SELF-PLAYING ORGAN AND PNEUMATiCU-'A'CTION THEREFOR.

Application filed July 7.1902.l

SPECIFICATION forming part ofl Letters Patent No.i733,917, dated July 14, 1903.

'Serial No.` 114,557. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH 1E. -PRANTIL a citizen ot' the United States, residing at'Chillicothe, in the county of Ross and State of rangement, and combination of the partsv v thereof.

Afurther object of the invention is to provide-improved means for separating the wind-l chest into individual chest with back and front compartments, whereby the bass and treble chests are made separate and distinct, and to provide such connections between'the compartments and the pneumatics that anautomatic operation is effected.

Astill furtherobject of the invention is to ,provide novel means for adjusting the pipevalves whereby they admit air direct to the pipes, an automatic pneumatic valve -lift having a dust-receptacle, and an improved tracker-board having downwardly-projectin g dust-receiving cells.

Various other special features in the actuating mechanism are employed to produce manyimproved results, which will be more particularly set forth in the specification and vpointed out in theclaims to follow.

In the accompanying drawings, forming part of this application, Figure 1 is a crosssection without the casing with the pipes re' moved. Fig. 2 is a rear view of the several bellows and air connections to the windchests. Fig. 3 is a section on the rim X X, Fig. 1, partly broken away. Fig. 4 is a lgngtudinal section of one of the air-chambers or individual wind chests, partly broken away and showing only part ofthe cell-valves. Fig. 5 is a'n' inverted planview of the windchests, partly broken away. Fig. 6 is a detail vert' cal section of cneof the pneumatics.

Fig. 7 is a perspective view of one of the bellcrank levers with its rods in position, partly broken away.- Fig. Sis a detail cross-section of one of the air-cells and its valves'. Fig. 9 is a perspective view of one ofthe pneumatic dust-chambers. f

The same numeral references denote the same parts throughout the several views of the drawings.

The general appearance of my organ is substantially the same as those of ordinary make when viewed from ,the exterior, the casing and ornamentation may be of any desired effect, and the pipes are ofthe usual The music-paper rolls or cylinders are of the usual type and location, and the size, shape, and material of the several parts may be such 'as are most suitable for producing 'the best results. The bass wind-chest 1 and the treble wind-chest 2 are separated by a'n intervallvor space 3, in which. space are operated bellcrank levers 4, pivoted or fulcrumed at 5.

The bass and treble wind-chests 1 and 2, respectively, are, divided'by partitions 1 and 2% into a series of air-chambers G, which are supplied with air from boxes 8, the latter being connected to the feed-bellows 9 by airlues 10. Air is admitted to the chambers ,6 by independent valves 11 of the boxes 8. Aircells 12 lead the air from the chambers 6 by way of throats 13 in the partitions 1 and 2 to the music-pipes. The air to these cells is controlled byvalves 15 and 16, having closing-springs 17 and pendants 1S. Each set or line of the treble-valves 15 is connected and operated together by tracker rods or wires 19, and the bass-valves 16 are likewise connected-and operated together by similar trackers 20. These trackers 19 andj 2O extend through and are secured to the pendants 18 and to the bell-crank levers by adjustingbuttons 21.

The pneumaticaction, of which there is of the latter, vand all being alike only one will be herein described in detail. It consists of a casing having a back 22, a front 23, having air-ducts 2 4 and 24, and hollow air-stem 25,

construction and connection to the air-cells.

one for each air-chamber, located at the rear.

supporting and communicating with a bellows 36 and 37, working in said separate air-chambers `to open and close ,valveways 38 and 39, and a bellows 40, connected to and operating the valve stem or rod 33. Secured within the pneumatic-casing and upon the bottom thereof is a block 41, having communication with the bellows 40 through a d ust receptacle or chamber 42, having a bottom opening 43 in communication with the discharge-aperture 28, and an air-channel 44, reaching from the chamber 42 to the air-duct 24. An air-pipe 43ck carries airtoa vacuum-bellows 44a through an opening 45 in the back 22 of the casing from the cylinder 32 to operate the bellows 40 and bellows 26. l

rlhe connection between the pneumatic-action and the valve-traekers consists of bellcrank levers 4, pivoted or fulcrumed at 5, and through one arm of which is adjustably attached trackers 19 and 2O by the buttons 2l. To the other lever-arm is secured a connectingrod 48, attached to the bellows 26, so that the latter works one line of each of the set of valves 15 and 16.

The tracker-board 49 has air-ducts 50, to which are connected air-pipes 51 in communication with the airducts 24 of the pneumatics,and the tracker-board is provided with dust-cells 52 below the rpoint of connection between said pipes and the board to collect dust or foreignmatter instead of having it enter the said pipes. Should-such mattei' escape in to the pipes, the same will be collected in -the dust-chambcr 42, whence it is removedthrough the valves 29. The perforated music-paper 53 is operated in the usual manner over the tracker-board by the rollers 54 and 55.

The operation is as follows: Supposing all the tracker-board ducts to be closed by the non-perforated portion of the'paper and all` the bellows 40 are closed, which closes valves 37 and opens valves 36 and bellows 26,when

a perforation of the music-paper passes over a duct in the tracker-hoard the air passes through a pipe 51, opening a bellows 40, which lifts the valve-stern and opens valves 37, simultaneously closing valve This action closes the bellows 26 and pulls the conneot- :ing-rods 48 downwardly and operates the bell.- cranlr levers to work the trackers and open the ' valves 15 and 16. y

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. rlhe combination,y with a pneumatic for organs having a casing, of a block secured in the casing in communications/ith the pneumatic andhaving a dustchamber, an airchannel extending from the chamber through the block, and a dust-discharge opening from ythe bottom of the chamber.

2. The combination, with the pneumatic having a casing, ay hollowstem projecting from the casing, a pneumatic secured on the vsaid stem in communication with the latter,

and a spring-valve hinged to the bottom of the casing, of a block secured within the cas- 'ing and having a dust-chamber discharging through the valve, and an air-channel leading from said chamber through the casing, a

pneumatic secured on the block in comlnuv nication with the dust-chamber, and the rod having valves and attached to the latter pneul matic.

3. The combination, with the wind-chests divided intoa series of air-chambers and separated by an interval or space, bell-crank levers fulcrumed to the chest-casings and operated in said .,space, the partitions of said chambers having a cell and a throat leading therefrom, spring-controlled valves hinged to the partitions, and tracker-rods connecting the valves with the .bell-crank levers, of the pneumatics having hollow stem projections bellows held by the projections and in coming the bellows with the bell-crank levers.

In witness whereof I hereunto set my hand in the presence of two Witnesses.
