ORGAN.

SPECIFICATION forming part of Letters Patent N 0. 464,270, dated December 1, 1891.

Application filed Tanuary 12, 1891. Serial lie. 377,422. (No model.)

To all whom it may concern:

Beit known that I, Moses D. VAN WINKLE, a citizen of the United States, residing at Bloomfield, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Organs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an action which shall not be deleteriously affected by changes which take place in respect to the humidity and temperature of the at; mosphere, but which shall work freely and promptly, regardless of those conditions, and to secure other advantages hereinafter specified.

The invention consists in the improved organ-action and in the combination and arrangement of the several parts thereof, as herein set forth, and finally pointed out in the claims.

Referring to the accompanying drawings, in which similar characters or letters of reference indicate corresponding parts in each of the several figures where they occur, Figure 1 represents in front elevation a parlororgan, the keys and the action being exposed, embodying my improvement; and Fig. 2 is a horizontal transverse section taken through line x of the same. Fig. 3 is a vertical transverse section taken through line 3 of Fig. 2.

In said drawings, a indicates the reedboards; I) the ports therein, which communicate with the reeds and through which the air escapes when the keys are being manipulated.

0 indicates the pallets, which are hinged or fulcrumed at or near the back edge of the reed-boards.

(1 indicates the lifting-rods arranged in front of the reed-boards and carrying lifters e, which connect with said pallets, and f indicates cushioned or lined covers, which are hinged to the reed-boards and cover the openings g, through which the reeds are inserted and removed when necessary. When this operation is being performed, the covers are opened, as

indicated by dotted lines in Fig 3, and when it is completed and the covers released they close automatically by a spring action, as will be understood. The said cushions or linings intervening between the covers and the reedboards may or may not be fastened to said covers and may work either with or ind ependent of them, as may be preferred.

The ports or air-escapes Z; are made in the top of the reed-boards instead of in the front thereof, as heretofore, and are covered by the pallets c, which are each provided with a cushioned or flexible valve h, which is considerably larger diametrically than the said ports and extends beyond the limits thereof, whereby any expansion or contraction which may take place in the pallets or reed-boards, owing to the varying conditions of the atmosphere, will not cause the valves to leak by the uncovering of the ports I), as is frequently the case with ordinary organs.

The pallets c,owing to the relative location of the ports, lie directly upon the top of the latter, which are thereby kept closed by the force of gravitation upon the pallets, as well as by the action of a spring 1', secured to the organ-case and engaging with said liftingrods, as shown in Fig. 3. The pallets being hinged or fulcrumed at or near the back edge of the reed-board, as stated, are, owing also to their length and to the location of the lifters, easily lifted, as will be obvious. The said lifters e are adjustable upon the lifting-rod (Z, and are held in position thereon by means of set-screws e, and engage with the pallets by means of a cushioned tenon e which enters a corresponding slot or groove in the end of said pallets, as will be understood upon reference to Figs. 2 and By means of these improvements I am enabled to effect a considerable saving in the cost of manufacture as well as in the expense of repairing, which are greatly reduced in consequence thereof.

Having thus described my invention, what I claim as new, and desire to have secured by Letters Patent of the United States, is

1. Au organ-action combining therein a reed-board having the air-escape ports Z) in the top thereof, pallets 0, provided with cushioned or elastic valves diametrically larger than said ports, a lifting-rod carrying adj ustable li'l'ters which connect with said pallets,

a spring engaging with said lifting-rod, the

normal tendency of which is to press the pallets upon the reed-board, and a hinged cover 5 to close the openings in the front of the reedboards, substantially as and for the purposes set forth.

2. In an organ-action, the combination, with pallets hinged or fulcruined atthe back edge [0 of the reed-board, of lifting-rods arranged in front of the reedboards, adjustable lifters carried by said lifting-rods and engaging with said pallets, and springs secured to the organcase and engaging with the liftingrods afore- 1' 5 said, as described, for the purposes set forth.

3. In an organ-action, the combination, with the reed-board having the ports I) in the top and the openings g in the front thereof, of the pallets 0, covering said ports I), and the hinged eoversficovcring saidopenings ,as described, for the purposes set forth.

4-. 111 an organ-action, the combination of a reed-board having the openings in the front thereof to admit of the insertion and withdrawal of the reeds, and the hinged eoversf, arranged to operate in connection therewith, as described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this filth day of October, 1890.

MOSES D. VAN WlNKLE.
