Specification formin art: Letters Patent No. 174,207, dated February 29, 1876; application filed v a October-29,1875.

Toall tohom it mag concern Be] it known that I, 'ARVID DAY'roN, of. Wolcottville, in' the county ofLitchfield and p j State of Connecticut, have invented certain Improvements in" Bellows forReed-Organs, of

a "which the following is a specification This inventionrelates' to the springs for collapsing thexfpumpers. and expanding the exhauster'of the bellowsfas ordinarily constructed for reed-organs; and itjconsists in the application of torsion-rods or wires of spring metal to the same, in such a manner that any force tending to expand the pumpe s (asby the action otQthe foot on the pedal in the usual manner) or to collapse the .exhauster will. twist :the said rods, as clearly shown. It also consists in the novel construction and arrangement of the parts, as wil -lbe hereinafter described.

In the drawings, Figure 1 is a front view, on a small scale, showing'the application of my device to the pumpers of an organ bellows. Fig. 2 is a plan of'an organ-bellows supplied with my improved form of spring. Fig. 3 is an endview of; the same.

A represents the fixed partition between the exhauster B and-the pumpers O (J. The former is hinged to the mortised strip vD, which communicates with he wind-chest of the organ. The latter are hinged at the bottom, and are operated by pedals in the usual manner. The normal position of the exhauster is that of expansion, and the normal position of the pumpers is that of collapse, as illustrated in Fig. 3, when the instrument is in repose. They are retained in this position by the tension of springs.

All the parts of the bellows above described are common to many instruments, and therefore form no part of my presentinvention.

now describe.

To hold the exhauster in itsnormal expanded position, I provide rods a a, of spring meal, with their ends b b b b bent nearly at right angles to the main stem, and at a proper angle with each other. One end, b, of each The parts constituting my invention I will rod is inserted in a block, 0, secured to th partition A, and the other 'endfli, slipped into asuitable bearing, 01, secured to the back of When'the ends-0t the rods pumpers O O is precisely the same as that t'orthe exhauster, and I have used the same lettersof reference for both; but the latter must be so arranged as to retain the pumpers in a collapsed normal'condition.

The advantages of this spring over the old hind, inclosed within the bellows, are obvious.

My spring is cheap and simple. It is outside of-th'e bellows, and easily reached for repair or removal. It at any time it should be necessary to release the bellows from the action of the springs, thisis readily done by slipping the ends 11 b from their bearings. The elasticity of the rods readily permits this, and also their replacement. v

I do not claim torsion-rods'broadly as my invention, and I am aware that they have been used as springs for valves of reed-organs, as shown in the patent of J. 1. Packard, of July 26, 1870; but

'What I do claim is- 1. The combination of the spring torsionrods 01. or, constructed and attached substantially as shown, with the bellows ot' a reed instrument, when the said rods are situated outside of the bellows, and one end of each is made;

readily releasable, as shown and specified.

2. The combination of the spring-rods a at, having bent ends b b b b, with'the bearings d d, and the bellows of a reed instrument, the whole being constructed and arranged substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
