IMPROVEMENT IN BELLOWS FOR REED-ORGANS.

To all persons to whom these presents may come:

Be it known that I, SAMUEL H. J oxns, of Boston, of the county of Suffolk,and the State of Massachusetts, have made a new and useful invention, having reference to the Bellows of Reed-Organs, or various other musical instruments of like nat-ure; andi do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figures l and 2 are side views, and,

Figure 3, a front view of a. reed-organ bellows provided with my invention.

In carrying out my said invention, I vcombine with the bellowsa mechanism for holding its lower' board stationary, at one end ,of it, at certaintimes, the same being in order to enable a player to accelerate the tremolo, so as to make it more expressive than it would be without such mechanism so applied.

My invention enables a better crescendo or diminuendo effect, or expression to be produced upon a single note. It therefore improves the quality as well as the toneof the instrument.

1n the drawings- A denotes au ordinary reed-organ bellows, of which' a is the stationary board, and b c, the movable top and bottom boards.

B is a stud extended from one end'of the bottom board, and to operate with a catch-lever, G, formed with a series of notches, (l d d, arranged init, in manner as represented.

This catch-lever, at its lower part, is to be pivoted to the frame I, of the instrument.

A connection-bar, D, jointed at one end to the catchlever, is at the other end jointed to a lever, E, arranged as represented, so as to turn ou a stationary pivot, e. l

Two springs, f f, are fastened at their lower parts to the opposite edges of the said lever E, and project above its upper end.

Between these springs the lower arm of a lever, F, extends, such leverhaving its fulcrum at g, and being formed and arranged, with respect to the leverE, in manner as represented.

The lower arm of the lever F is cam-shaped, as shown, thesame being to enable the lever, at either extreme of its movement, against either' of the spri n gs,

to hold the spring strained, in order that vthe latch may either catch upon, or be discharged from the stud at the proper time.

Vifhilc the bellows may be in operation, and when it may be desirable to arrest the movement of the end of the lower board thereof, it will be necessary for the performer to push the upper end ot the lever F forward. This will cause thelatch to be borne against the stud.

Should a notch of the latch be in a. correct position to receive the stud, the latch will atA once catch upon the stud, but should the stud not be in a. proper position to enter a notch of the latch, at the time ofthe said movement of the lever F, the spring against which such lever may be pressing, will effect the engagement of the latch and stud the instant ailier the stud and a notch of the latch may come into conjunction.

Thus it will be seen that the purpose ofthe springs, andthe upper, or cammed lever, is to enable the engagement, or disengagement of the latch and the stud to be effected without requiring the performer-to keep his hand ou the lever longer than may be necessary to effect a movement of it in either direction. The single lever, without the springs, and the other, or cammed lever, would answer to effect the movements ofthe latch, but in this case the time required to accomplish such, would often beadeterment to the playing of the performer.

Holding the bottom board stationary, at or near one end of it, does not prevent the board from having slight vibrations at its other end, such being productive of the eiects sought to-be produced by the im provement.

I claim, in combination with an organ-bellows, as represented, a mechanism for latching, or estopping the movement of the bottom board, at one end thereof, while the upper, or exhausting-board of the bellows may be in operation, the same being to produce. an effect, or effects, as set forth.

I also claim the combination of the springs ff, and the cammed lever' F, with the bellows A, and its latchiug-apparatus, consisting of the stud B, the leverlatch O, the connecting-bar l), and the lever E; the whole being substantially as described.
