Letters Patent No. 97 ,803, dated December 14,1869.

IMPROVEAIENT m ORG-AN-BBLLO'WS.

The Schedule referred to in the Letters Patent and making part of the lame.

T 0 all whom it may concern.-

Be it known that I, J. R. PERRY, of Wilkesbarre, in the county of Luzerne, and State of Pennsylvania, have invented a new and useful Improvement in Orgain-Bellows; and I do hereby declare that the following is a full, clear, and exact description of the same, such as will enable any person skilled in the arts to construct and use it, reference being had to the-accompanying drawings, forming part of this specification.

This invention relates to a new method of constructing and operating organ-bellows, so as to avoid the unpleasant noise usually heard, when operating them in the ordinary way, occasioned by the suction of the air-valves or clappers against their seats.

It also consists in the position of the same, with reference to the reed-board, keys, and also foot-boards, by which a direct motion is obtained, thereby avoiding the use of pulleys and other devices, to produce the necessary motion on the exhaust-boards.

It consists also in saving the construction of a condrrctor or air-passage from the reeds to the receivingchamber, and avoiding the liability of splitting, by placing the bellows in a horizontal, instead of a vertical posit-ion.

It consists also in a double receiving-chamber, from which the air is drawn, thus avoiding the abrupt suction or force upon the reeds, as compared to other methods.

It consists also in a device for regulating the posi tion of the springs, which react against the exhaustboards.

Figure 1 represents an end-view, showing the positions of the boards, springs,.valves, air-chambers, exhausts, strap, and foot board; also, the device for adjusting the springs, to suit the action of the vibrating-board of bellows.

A represents a chamber on which the reed-board may be secured, air-tight.

B is an end view of the bellows-board, placed in a horizontal position, with an air-passage, O, which allows it to pass from the reeds into the air-chamber D, and

E is a stcclspring, one or more of which are used to expand the receiving-chamber when pumping.

F is a vibrating-board, the sides and end of which are covered with gum-cloth or leather, and attached to board B, forming an air-tight chamber.

It has an air-passage, G, admitting the air into the second chamber 1, through the valve H and its smaller chamber.

The valve H is hinged or glued to the board F at K, and is operated by drawing on the exhaustboard with the foot-board.

The passages at G and G require no valves.

At L there is an air-passage through the exhaustboards M, admitting the air into chamber N, which is formed with a valve, 0, and glued to the exhaustboards in a position so that while playing, its tendency is to remain closed, until forced open by the escaping air, which is driven out by the reacting spring I, which spring rests on the frame Q and adjustable boards R, which are secured to horizontal board B with a screw.

It will be seen that when the exhaust-boards are operated by the strap 8 or foot-boards, as in playing, the exhaust-boards will draw out of the chamber 1, and then through valve H, a quantity of air corresponding to their size, and the depth of stroke given; but as it is first taken from chamber I, the effect of pressure is more uniform upon the reeds than if drawn directly from the. first chamber D, and as there will always be a quantity of air in chamber I, it closes valve H without any perceptible noise.

At the end of chamber I and valve'H, the opening formed by the pieces used in constructing the chamher is closed by apiece of gum-cloth or leather, so as to compel the air to pass through the valve H.

By hlnging the exhaust-boards to the vibratingboard F, a direct connection with the foot-board is obtained, by the straps used in working them, and avoids the necessity of pnlleysto connect them, in obtaining the requisite movements; and by the use of the additional chamber I, and the position of the valves H and 0, they operate without the least perceptible noise. 7

The adjustable boards R of the spring-frame are to be fastened to the inside of the organmse, when their proper position is ascertained, which is found by exhausting chamber 1), and swinging the vibrating board F and the exhaust-board into their ex-, treme positions, which will determine the point to locate them, 7

Figure 2 represents a top view of chamber 1, airpassage G, (which may be holes bored 'or'a continuous slot,) valve H, and its fastening to bottom of vibrating-board F.

The opening over air-holes G must be closed.

Having thus fully described my invention,

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The additional chamber I, in combination with the chamber formed by the suspended valve H, in the manner and for the purpose set forth.

2. The chamber N, attached tothe exhaust-boards, as arranged and for the purpose specified.

3. Discla-iming the special arrangement of A. W. \Vilcox, patented April 28th, 1868, the combination of the valve-chamber H, recess I, and chamber N, in the manner and for the purpose specified.

4. The adjustable frame It, combined with the organ-case, for the support of the spring P, substantially as described.
