TO ALL WHOM l MAY CONCERN:

Be it known thet S. A. JEWETT, of Cleveland, in the county of Cuyahoga, end Stets ci' Ohio, have invented certain new and usefui improvements in Melodeons and rgens; end do hereby declare that the following is n full and com plete description thereof, reference being had to the eccomps'nying drawings, making e. part e? this specification, in which- Figure 1 is s tcp view of the organ end bellows with the cover removed.

Figure 2 is e front view. v

Figure 3 is a' top view with the bellows and keys detached.

Figure 4 is :ibook view. y

Like letters of reference refer to like parts in the different views.

The general construction and arrangement of this organ is the seme es that common tc sli cabinet end cottage organs now in general use, the arrangement of the key-board, the reeds, bellows, and pedal being the seme, es will be seen. I

A, tig. l, being the benk of keys, C, gs. 3 and 4, the reeds, D the tubes in which the reeds ere placed, E the bellows, of which` l" is the exhaust veive.

My invention consists of the introduction of a. system of snb-eenuels or independent manuals, for the purpose of producing remote octave or intermediate tones, thereby adding volume end variety of tone to the organ, melodcon, or pieno-forte, producing substantially the seme eiiects es they pedal sub-hess in ergens, and for which purpose they are designed, which iseecomplished in rtheqoliowing manner: "1, iig. 3, ere levers placed diegonally across the. body of the instrument, below the key-board, end which are e. part of en octave in number; they are so arranged, in relation to the first or lower oct-eve, that the extreme end coincides with the keys by which the reeds of said octave are operated. rhese levers ere piveted te the under side of the piece et the points z, and the short arms of which are connected to the keys A by the rods Hf, iig. li, by passing the ends of them' through the holes a in the end of the levers7 and the upper end through corresponding holes in the ends of the keys, which arelengthened out by the extension pieces provided for that purpose. ilie washers b secure the rods in position, and .also prevent any undue noise arising from the action of thelevers and. reds while being used. The longarm of the lever extends to the front oi' the instrument, end the position et whieh,.in relation to the keys, coincides with the second octave :is the short arm coincides with the first octeve as above stated. It will be seen by this that any number of levers may be introduced, according to the size or capacity of the instrument. These levers are operated by the rods J, to which they ere connected by passing them through the ends of the levers, as ere the rods et the'opposite end, end ere secured by the nuts c, one above end one belenr the lever. These rods and connections ere shown in tig. 2., e. section of the cese being brel-:en away in order that they muy be seen. These connecting-rods project np through the side of the cese, end the projecting ends provided with the tnppet-s K, which ere arranged in double rows immediately in front of the keys along the edge of.the case, as shown in iig. 3, the dii-rk tnppets being the seminotes, end the white the whole tones, thus reletively corresponding vwith the manuels of the boord. Y

Having thus described thc construction and eirangementof the invention, and are celled independent manuels, I-now proceed to show the operation of the same, which is es t'ollows: it will be seen. arrangenient of levers, end the wey in which they are connected to the keys, thot on depressing the long erm of tint' same, by means of the teppets tojvhich they ere connected by the rod Hf, that the roer ends of the levers or, thereby reised up, and in consequence the keys ore pressed down bythe reverse ectienof the lever exerted against the extension pieces I, the ei'iect upon the keys being the seme es though they had been pressed down by the fingers, hence the reed-valves are opened es reedilyend with es much fsciii by the tappeti; es by the keys. These tappets ere intended to be manipulated by the little nger of the lei't hand; the other three fingers und thumb can then lill in or play the harmony, thus leaving the right hand free for additional harmony or solo playino. In the cabinet organ especially this is of great velue, for with two feet only no player een use the pedal, key-board, supply the air, and operate the swell all at one time, but with the independent manuels in place of the pedal keys, and foru-'hichthey ere substituted, ell the effects can bc produced, thus dispensing with the aid of on essistent, andputting the whole capacity of the instrument under the control of the player, which a great iles'idcrstum in producing artistic effector expressionin musie Also, in the larger size of the cabinet organ, orchestral effect may be finely rendered byintrod ucng tones or strains in vmusic of di'erent power, quality, und pitch from the accompaniment; audso also in-the parlor organ equally pleasing effect may be given suitable for the drawxngfwom -or home circle. lftV is obvious that by the introduction of 4the independentmanuals, the player is enabled .to reach or produce. remote or intermediate tones-without the necessity of his hand traversing the board for that purpose in playing the second or third octaves. Notes in the first are reached by'striking the tappets withequal certainty of effect and much less labor than could he donc bythe hand upon the keys,

and in less time. for the tappets being immediately in front o'f the key,.-and under the hand, no appreciabley time is required to strike them, es would be in passing the hand over the keys and back in order to clfect the ssnieresult. lAnd es a scale of independent manuals mcy be introduced for each octave,'the exertion of the player is in consequence very much reduced, without the leest interferenccwith the skill and accomplishment of' the performer. The independent manuals, as above described, operate the reeds or pellets through the introlduction of levers so arranged for that purpose.- But an immediate or direct connection may he made so :1s to produce the same effect, if so desired, withoutcompromising the general results.

What I claim as my invention, and desire to secure by Letters Patent, is y The tappets or independent manuals K, rods J, levers G, and rods H, incombinnticn with the keys A and 'reeds C, in the manner and for the purpose set forth.
