IMPROVEMENT IN 'TREMOLOS FOR WIND-INSTRUMENTS.

the Schedule referred to in these LetterfPatentgnd-'rnaking" 'part of the sama W yf: '2:' *Y

To all whom it may concern:

Be it known that I, ROBERT W. PAIN, ofthe city and State of New York, haveinvented and made a certain new and useful Improvement in Melodeons, and similar instruments;y and I do hereby declare the following to be a full, clear, and exact descliptiou of the said invention, reference being had to the annexed drawing, making part of this spccioatiou, wherein- Figure 1 is a cross-section of said improved melodeon ;A

Figure 2 is a sectional plan at the line a; x; and

Figure 3 is a sectional plan below the line y y, showing the treadle, and part-s that opexate'the valves.

Similar marks of reference denote the same parts.

Melodeons have heretofore been made with atremoloattachment, consisting of' a hinged valve, placed in the air-passages, so as to produce a vibration and tremulousaction in the wind. in musical instruments, are conversant with the fact that the tremolo-att-aclnnent is frequently ont of repair, and that this arises mainly from the valve being hinged.

The nature ofmy said invention consists in atremoloattachment, formed of'a valve that is held to its place over aseat, without the use of a hinge, so that the Aair can escape all around the valve with uniformity, or nearly so, said valve being either globular, and confined by a cage, or set upon a spring, so. that there is -no hinge to wear out by the rapid vibration, or become obstructed by dust or othermatter floating in the air.

Manufacturers, and dealersI Beneath the treadle o is a lever, q, having a stud that passes through a slot in the treadle, so that it can be operated by the foot while playing, and act upon the lever -r, rod s, bent lever t, and rod u, or similar connections to the lever p, that acts to close the valve c upon the passage-way k, so that the air shall pass through the tremolo instead of through the opening k, as is the case when thefvalve over the opening k is ina normal position.

VIn'tbe chamber l is a valve, n, over an opening in the bottoni of said chamber. This valve should be a ball or disk, of su'icient weight to be moved by the pressure of the air, and it is confined to a limited amount of vibration by a cage over it, or by a spring, u, to which it is connected, so that when the valve lv closes the opening k, the air will be' drawn from the vreeds up beneath the valve n, thence to the bellows e.

The weight of' the valve 'n causes it to fall upon its seat with a Iapid, tremulous motion, as the air escapes through beneath it. Hence, the sound produced by the reeds will be tremulous, and, by the instant opening or closing of the valve c, (at k,) so the tremolo will be stopped or brought into action.

By this construction, the air escapes all around the valve n with uniformity, keeping the seat free and clear. The valve lifts bodily oil" the. seat, and is parallel, or .nearly so, to the same, and there is no hinge to become injured or obstructed. Hence, my valve is not as liable to injury as the swinging valves.

What I claim, and desire to secure by Letters Patent, is-

Avalve for the tremolo-attachment of a melodeon, or similar instrument, formed in the manner specified, so that when the valve opens, the air can escape freely all around said valve, for the' purposes specified.

In witness whereof, I have hereunto set my signaf ture, this 27th day of June, A. D. 1868.
