Letters Patent No 77,661, dated May 5, 1868.

maovsitrnr m REED-ORGAN renews. v

Be it known that I, Joins SCH/W250i NewI-Inven, in the county of New Haven, and Stateof Connecticut,

have invented a new Improvement in Reed-Organ Bellows; and I do hereby declare the following, when taken in connection with theuccompsnyin'g drawings, and the letters of reference marked thereon, to be a full, clear,

end exact description 05 the same, and which said drawings constitutepnrt of this specification, and represent, in'-- Figure 1, an end view, Figure 2 a top view, andin Figure 3 a transverse section. p y p r. This invention relates to an improvement in thatcluss of bellowssuch as are now commonly used in-reedinstruments, and draw or suck the air through-the reed, instead of forcing'it, and the invention consists in the arrangement of collapsing-chambers in combination with the operating-bellows, so that the said chambers combined form a large chamber or reservoir, acting in connection with the bellows, so that the amountojf power applied to drawing the air is very greatly increascd,.and thereby a moreregular draught kept up, and enables the performer to operate the bellows regularly and steadily. v p

In order to the clear understanding of my in s'emtion,- I will proceed to describe the same, as illustrated in the accompanying drawings. a v i A is the connection with the air-chamber, with which said air-chainber the rc eds'are in connectionlin tho usual mannetw Below the passage A is a fixed partition, B, and ionthe front, hingedat the top, is another .parti'tio'n, (I, attached to the partition B by'flexibl'e onclosing-sides,-D, and-withinthe bellows a proper spring,

E, is arranged, to support the partition 0 at the full extent of the flexible covering no'm the partition B. On the said partition 0 the two bellows F and G are arranged, as seen in fig. 3, so as to be operated by thetreadles, each indepcnd'entof the other, in tho usual manner: Valves, d, on the bellows open as the bellows 'oredepressed, to permit the. exit of the-air from the bellows; then,- when drawn forward, a vacuum is'formed in the bellows G,

. (by closing the'villvcs d,),which vacuum is supplied from the cha'rnbcr H, between the two partitions Band C,

the-air within the chamber passing'through valves into the bellows, thus exhausting the air from the chamhcr H. The partition 0 is depressed, the bellows again pressed forward, the air inthebcllows-passingout as before, and, so continuing, the air will be entirely exhausted, or nearly so, from both bellows, and the chamber- H being in connection with the air-chamber through the passage A when the valves are open, the oxternaluinrushes through'the valve and reed to supply the vacuum-formed as aforesaid.

Thus for the arrangement is common andwell known, and by this arrangement a ditiiculty occurs, inthat when -the air has been entirely'exhau'st'ed in the chamber H" and the' bcllows, thcperi'ormer is obliged, to zest upon the treudlcs, andthe draught comes so strong at such times as to materially detract from the soundot' the reeds, as the stronger the drought the stronger the sound; therefore grcat'care is required by the performer in operating the bellows. To overcome: this diiliculty, andregulato more perfectly the operation, I arrange upon the back of the partition 13 two other chambers, I and K, similar in construction to the chamber H, as

seen infig.. 3, the chamber I communicating through the passage A to the air ciiiiiiiber-in-tlre some manner as the chamber- I-I; and-through th'e partitioti B, I .form'openings, s, cover-ed upon the bellows sideby yalves, It, and an opening, it, through the partition L, between the chambers I and K. By this constructiom'when the bellows is expanded, 'air is drawn alike from both chambers, I and H, through tbeirrespectivo'valves, fond h,'bu't when the -bellows is fully expanded, then the two chambers, I and H, have been alike contracted, and ihe'bcllows is returned and the valves fond 7; closed. The'opening between the chambers Ian'd K is left'free',

and air passes through the opening from the chamber K until the three chambers, 11, I, and K, are equalised; therefore the operator-{keeping up a constunt'and steady blowing, the three chambers, equalized in thoniunnor described, maintain a constnntand-stead'y draught from the air-chamber, and the irregular blasts" often board in thomeIodeo'n, as commonly constructed, are by thisv arrangement entirely avoided.

Having thus fully Jesribed uiy ini'qntion what Iciuim as new nmi usefui, and desire to securi: ByLetters The arrangement 'offihe two chamb'ers I and K, or either of them, hp'on-on side of m fixed partition, B,

in combination with the chamber 11 and bellows F and G upon the other side of the said partition, and ail of the'aaid partitions connecting-with the passage A, and bonatructed a6 as to opeqate togati rer, in the manner and for the purpose herein set fox-tin. JOEN SCHATZ.
