OLIVER H. ARNO, OF \VILMINGTON, ASSIGNOR TO AMERICAN AUTOMATIC ORGAN COMPANY, OF BOSTON, MASSACHUSETTS.

MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 233,721, dated October 26, 1880.

" Application filed June 18, 1880. (No model.) Patented in England May 26, 1880.

To all whom it may concern Be it known that I, OLIVER H. ARNO, of Wilmington, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Mechanical Musical Instruments, of which the following is a full, clear, and exact description.

This invention pertains to that class of me chanical musical instruments arranged by the 1o passage of a perforated paper strip to secure the automatic playing of the instrument in accordance with the disposition of the perforated aud unperforated portions of the paper strip in relation to each other, and to the I 5 mechanism for opening and closing the reedvalve, &c.

In a patentgranted to me May 18,1880, and numbered 227,714, the perforated strip is provided with two lines of perforations, the

perforations of one line being for opening, and the perforations of the other line being for closing, a sliding valve through the medium of two separate levers.

The object of my present invention is to dispense with the line of perforations for closing the sliding valve, and also to open or close said valve by means of a single lever.

The invention consists of a reed-valve arranged to slide to open and close the reed, and

0 of a lever connected to the valve, and constructed and otherwise arranged and disposed in such relation thereto and to the rows of perforations in the paper strip which correspond to such reed that in thepassage of 5 the perforated and unperforated portions of the perforated strip by a given point the lever opens the valve at the passage of each perforated portion, and so keeps it open for the length ofsuch perforation, and closes the valve at the passage of such unperforated portion, and so keeps it closed for the length of such unperfora-ted portion, all substantially as hereinafter described.

In the accompanying plate of drawings my 5 invention is illustrated, Figures 1 and 2 being vertical sections in the line of travel of the perforated strip, the one showing the valve as closed and the other as opened.

In the drawings, A represents a horizontal bed or raceway. Along this bed and under a cross-block, B, the perforated strip of paper 0 passes, suitable mechanism-such as feedrolls-bei n g employed to secure the continuous passage of the paper strip.

The paper strip 0 is provided with a series ofparallel rows of perforations, and each row runs in the line of travel of the strip through the raceway. In line with each row of perforations there is an opening, 0,.iu the raceway, and block B and a horizontal lever, D, below the raceway A.

Each horizontal lever D, at its one end, 6, is hung to a fulcrum-pin, a, and near its other end,f, it has on its upper side a wedge-piece,

b, suitably located to enter the opening 0 in the raceway and block in line with it.

E is a bent spring placed below each lever. This spring at one end is fastened to a block, (I, and at the other end it presses upwardly against the under side of its lever.

F is a vertical arm attached to each lever, and at its lower end hinged to a reed-valve, G, arranged to slide horizontally over the face of the reed-chamber H. When this valve is slid in one direction the reed-valve is opened, and when it is slid in the other direction the valve is closed, and the arrangement of each valve and its lever-connection described is such that the downward swing of the lever closes, and the upward swing of the lever opens, the valve.

The opening of the valve is against the pressure of the spring, and its closing is with such pressure.

As each lever is arranged in the travel of the perforated strip 0 through the raceway, it opens its valve and holds it open, when a perforated portion of the paper strip is passiug by its wedge-piece b, and it closes its valve and holds it closed when an unperforated por- 0 tion of the paper strip is passing by its wedgepiece 11, all as is plain without further description.

Having thus described my invention, what I claim, and desire to secure by Letters Pat- 5 cut, is-

In a mechanical musical instrument in which a perforated strip, 0, is employed, the combination of slide-valve G with the single lever 1), arranged and connected together, and in relation to the perforated and nnperforated portions of the strip 0, substantially in the manner described, whereby the said slide-valve is both opened and closed by the single lever D, as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

OLIVER H. ARNO.
