PEDAL REED-ORGAN ATTACHMENT FOR ORGANS OR PlANOS.

SPECIFICATION forming part of Letters Patent No. 390,051, dated September 25, 1888.

Application filed June 5, 1888. Serial No. 276,100. (No m del.)

To c ZZ whom, it may concern.-

Be it known that l, ALoIs ALLMU'rn', of the city, county, and State of New York, have invented certain new and useful Improvements in Pedal Beed-Grgan Attachments for Pianos and Organs, of which the following is a specification.

This invention relates to an improved pedal reed-organ attachment for pianos and organs, which is to be conveniently used by organists and students of the organ in connection with a piano or reed-organ, either for practicing at home or for combining the effects of the piano with the bass tones of an organ; and the invention consists of a pedal reed-organ attachment for pianos and organs in which the bellows and reed-case are arranged in a seatframe, the bellows being worked by a handlever or other suitable power, while the reedvalves are operated by fuleruined levers, while intermediate pedal-levers provided with slidepieces having abutments and wedgepieces serve to operate the stop of said reeds, so as to open or close either set or both sets of reeds, as desired.

In the accompanying drawings, Figure 1 represents a side elevation with a part broken away, showing my improved pedal reed organ attachment in position for use with an upright piano. Fig. 2 is a plan of the attachment, partly in horizontal section on line m, Fig. 1, of the seat-frame of the attachment, showing the pedals and mode of operating the same; and Fig. 3 is a vertical longitudinal section of the seat-frame on line 31y, Fig. 1, showing the bellows, reedcase, and stop- Fig. 4 is a vertical transverse section of the attachment on linez .2", Fig. 2; and Fig. 5 is a vertical transverse section on line it 7;, Fig. 2, showing one of the pedallevers for operating the stops of the reeds.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the base-frame of my improved pedal reed-organ attachment for pianos and organs. At the front part of the base-frame A are arranged a number of pedals, B B, which are fulcrumed to a common pivotrod, 1), supported in lugs b of the base-frame A. To the rear end of the base-frame A is applied the seat-franie G, at the interior of which are located the reed-case D, wind-chest D, bellows E E, and thewindregulating bel lows F, as shown in Figs. 3 and 4'.

The pedals B B engage short intermediate levers, B, which are fulcrumed to a common. pivot-rod, d, that is supported by lugs (Z of the base frame A. the rear ends of the fill crumed levers B engaging the front ends of the hinged and spring-actuated reed-valves D as shown clearly in Fig. 4. By depressing the pedals B the reed-valves D are opened and the reeds sounded.

The bellows E E are arranged, respectively, above and below a horizontal partition, 0, of the seat-frame O, the movable side walls of the bellows being connected by a pivot-rod, e, which passes through an opening, 0, in the partition 0, so that when the bellows E are operated by a hand-lever, E or by a suitable motor connected to the lever, the bellows E and E are alternately expanded or contracted, so as to alternately supply compressed air through the channels c to the wind-chest D ofthe reedcase D,the surplus ofairbeing taken up by the regulating-bellows F, which are arranged on top of the wind-chest D and acted upon by spiral springs f, which are interposed between the movable side wall of the bellows F and the partition 0, as shown in Fig. 3.

The regulating-bellows F are stopped by a stop,f, when expanded to their full extent, and serve for the purpose of keeping up the regular and continuous supply of air to the reed-valves when playing the organ attachment. The operating-lever E of the bellows E E is guided in a suitable manner and extended through a slotted opening, 6, in the end wall of the seat-frame C to the outside of the same, so that it may be worked either by hand or by a treadle, or by a motor whenever the reed-organ attachment is desired to be used.

If the bellows are to be operated by a motor, the latter is arranged at one end of the seatframe 0, and connected by a pitnian in the usual manner to the lever E so as to produce the proper working of the bellows.

Intermediately between the pedals Bare arranged pedal-levers P P, which are pivoted at their front ends, and which serve for the purpose of opening or closing the stops of the reeds, of which, preferably, two are arranged-an eight and a sixteen foot stop. The eightfoot stop is opened or closed by the pedal-levers P P at one side of the attachment, while the sixteen-foot stop is operated by the pedal-levers I? at the other side of the same. The pedal-levers P P are each pro vided with a slide-plate, p, which is guided on the pedal-levers and provided with an abutment, p, and with a wedge-piece, 1, back of said abutment, the tapering end of which extends under a fixed yoke-piecap of the baseframe A,so that when the slide-platep is pushed backward by the pressure of the foot on the abutment 11* the thinner end of the wedgepiecep is moved under the fixed piece p and the pedal-lever thereby retained in lowered position.

The pedal-levers I or P are connected by rods 17* with stop-Valves p in the wind-chest, so that either the eight or sixteen foot stop can be opened, or both,when both levers P 1? are depressed. On depressing the pedals B the reeds are sounded as the necessary wind is admitted from the wind-chest to the reed-case. On releasing the wedge-piece p from the fixed piece p the stop-valve is closed again. In this manner either one or both stops may be opened or closed as required by the player.

The attachment is independent of and not connected with the piano or organ with which it is to be used, so that it can be removedafter use and put aside, or moved up to the piano or organ when required for use. As the reedcase and bellows are arranged in the seatframe, no eXtra space is taken up by the same, while they are also out of sight.

The attachment can be used with any style of piano or organ, and forms a comparatively cheap and convenient device, by which not only the organist and students of the organ can practice at home, but by which also the effects ofapiano or reed-organ can beblended with the bass tones of an organ in a very effective and attractive manner. It can also be used for accompanying orchestral instruments, as it supplies the full bass tones for the same, it being portable and readily taken to the place where it is to be used.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination, in a pedal reed-organ attachment for pianos and organs, of a series of pedals,reed-valves operated thereby, areedcase, a wind-chest for said reed-case, pedal-levers located between the pedals and provided with setting devices, stop-valves in said windchest, and connecting-rods between said pedallevers and stop-valves, substantially as set forth.

2. The combination of a series of fulcrumed pedals, intermediate levers, reed-valves operated by said levers, a reed-case containing the reeds, a windchest above the reed-case, intermediate pedal-levers provided with slideplates and wedge-pieces, valves in said windchest, and connecting-rods between the pedallevers and valves, substantially as set forth.

3. In apedal reed -organ attachment for pianos and organs, the combination, with the pedal -levers P, provided with slide plates 10, having projecting abutments 11* and wedgepieces 1), of yoke-shaped pieces 19 located at the rear of the wedgepieces, stop-valves 19", located in the wind-chest, and pivot-rods connecting the pedal-levers and stop-valves, substantially as set forth.

4. In a pedal reed organ attachment for pianos and organs, the combination of a sup porting base-frame, a series of pedals pivoted to said frame, a seat-frame supported on said base-frame, reed-valves operated by the pedals, a reed-case, ind-chest and bellowslocated in the seat-frame, stop-valves in the windchest, pedal-levers provided with setting devices, and connecting-rods between the pedallevers and stop valves, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ALOIS ALLMUTH.
