ORGAN-SWELL.

SPECIFICATION forming part of Letters Patent No. 244,351, dated July 12, 1881.

Application filed April 23, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMEs H. WHITE, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Organ-Swells; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters ofreferen ce marked thereon, to be a full, clear, and exact description of the same, and

[O which said drawings constitute part of this specification, and represent, in-

Figure 1, a front view; Fig. 2, section.

This invention relates to an improvement in swells for organs, with special reference to reed-organs.

In the usual construction the door or flap by which the swell is opened or closed is hinged at one edge, so asjto open at the opposite edge,

the inner face of the door closing against the edge of the chamber. A considerablemovement is therefore required, sufficient to give a clear or direct passage of sound therefrom.

The object of this invention is to improve 2 5 the opening, whereby a clearer passage is opened from the swell and it consists in the arrangement of the gate between the upper and lower sides of the chamber in an inclined position, so that the upper edge takes its bear- 0 ing upon the under surface of the upper side, and its lower edge takes its bearing upon the the upper surface of the under side, the hinging point being between the two edges of the door, so that in turning it opens both 5 above and below, and so that in closing the two edges are forced into close contact with corresponding surfaces in the chamber, as more fully hereinafter described.

A represents the lower side or floor, and "B 0 the upper side or top, of the chamber 0, from which the swell opens. D, the door or flap, is

a vertical arranged in a position inclined to the bottom and top A B, its upper and loweredgebeveled to correspond with the inner surfaceof the boty tom and top, as seen in Fig. 2. 4 5

Hinges E are applied to the chamber and to the flap so that the pivot 0 comes at apoint between the upperand lower edge of the flap; hence, when the flap is turned to open the swell, as in Fig. 2, the upper edge turns inward from the top and the lower edge outward from the bottom, making an opening above and below directly into the chamber, and without the circuitous passage in swells as usually constructed. The upper and lower edges of the flap are provided with packing, and because of its inclined position relative to the top and bottom it wedges between the two, when closed, by the action of the spring F or other applied force, so thatthe packingis made complete, and far more perfect than can be when the meeting surfaces come flat together, as in the usual construction.

Another advantage of this construction is that a direct opening, both at the top and hot tom, doubles the opening which occurs when the flap is hinged close to one edge, as in the usual construction; hence a less movement of the flap is necessary to produce the same result.

G represents the arm attached to the flap 7c as a means for opening it; but the arrangement for opening it differs in difl'erent organs.

I claim- The swell for reed-organs consisting of the flap D, arranged in a position inclined to the top and bottom ot'the chamber, with the hinges pivoted between the upper and lower edges of the flap, substantially as described.

J. H. WHITE.
