MECHANICAL MUSiCAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 326,172, dated September 15,1885.

A pplicalion filed April 1, 1882.

To aZZ whom it may concern.-

Be it known that I, FRANK STONE, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Mechanical Musical Instruments; and I declare the following to beadescription of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The objects of my present invention are, first, to provide an efficient automatically- 1 playing instrument adapted for performing music of extensive range, and for giving variety of expression to the music; second, to afford a convenient means for connecting the music-sheet to the winding spool or roller,

2 and obviate the necessity of threading it through the raceway or inserting its ends beneath the finger-rail; third, to provide a simple and convenient operating mechanism for winding and rewinding the music-sheet as desired; fourth, to perfect, locate, and adjust the several parts of the mechanism in such manner and form as will make a neat, serviceable, convenient, and desirable instrument adapted for cabinet-cases and for house- 0 hold or other purposes where a strong fulltoned instrument is required. These objects I. attain by mechanism constructed and organized for operation substantially as illustrated in the drawings and hereinafter described,

5 the particular subject-matter claimed being definitely specified.

In the drawings, Figure 1 is a plan view of my improved instrument without the case. Fig. 2 is abottom view of the sounding-board and stop-action devices. Fig. 3 is a vertical section through the case, showing an end View of the action mechanism. Fig. 4 is a sectional plan on larger scale, showing one end of the action mechanism, the upper por- 5 tions being shown as broken away to reveal parts beneath. Fig. 5 is a transverse vertical section through the action mechanism. Fig. 6 is a similar section of the race and fingerrail, showing the latter as in elevated posi- (No modrl.)

tion. Fig. 7 illustrates the manner of connecting the music-spool to its driving-gear.

In the reference to parts of the drawings, A denotes the action-bed or support-piece, which serves as a foundation for the various parts of the mechanism.

B indicates the bellows apparatus,connected with said action-bed and located within the lower part of the case 0, in a manner similar to an ordinary reed-organ bellows, the exhausters B being connected to foot-pedals B and the bellows operated for exhausting the air from the wind-chamber A by the depression of said pedals in the usual manner.

D indicates the sounding-board, forming the top of wind-chamber A, and supporting the tube-board E, which latter is constructed with a series of reed-sets arranged in overlying offset courses, with their downwardextending air-passages c, communicating with auxiliary chambers e, in which are located mutes or valves, F, for isolating or stopping off the several sets of reeds as desired. The front of the tube-board is made with an inclined face, the months or inlets being covered by a seat-piece, E, having air-ducts (1 formed through it and covering the whole front of the tube-board, as shown. Tip-up or rolling valves I are arranged for closing the air-ducts cl. Said valves I are independently hinged to the seat-piece and connected in series of two, three, or more to operatingbars I, and said bars are in turn connected by flexible straps I to the angle-levers G, located beneath. the raceway over which the music-sheet is made to travel.

The tubeboard E, reeds It, and valve devices I and F are constructed and arranged substantially as described and claimed in my application for separate Letters Patent of even date herewith, No. 56,996.

H indicates the table or race over which the perforated music-sheet M passes as it is drawn from the spool M to the winding-roll L. The race-bar H is formed of several pieces joined and arranged in the manner indicated. It has an open central space for the play of the levers G, and the top portion H is removable to allow access to thelevers G. lVing-pieces H extend from the ends of the raceway H to the sides of the case to fill the space and form a neat finish. The actuating-levers G have their fulcrum or pivot support on the racebar H, and said levers a-relocated atintervals along the width of the race corresponding with the lateral location of the valves l or the reedtnbes. The forward arms of said levers G are provided with heads G that extend upward through proper openings in the raceway and stand with their faces flush, or nearly so, with the top surface of the race-bar or in contact with the under side of the music sheet. Springs G are provided for retaining said levers with their ends G in elevated position. Said springs are in the present instance formed of wire, and are secured to a strip at tached along the back of the racebar H, with their ends arranged to press on the levers at a position just below the fulcrum-bearings, so

as to give a quick sensitive action. A rod, g, extends through the coils of the several springs for supporting and retaining them in proper relative position. A buffer-bar, G, is fixedin rear of thelowerends of thelevers G, having a suitable felt or cushioned surface against which said levers are stopped when the valves are opened and the movement of the valves, levers, and fingers thereby limited as required.

Immediately above the raceway and extending across the forward part of the instrument is a finger-bar, K, supporting a series of levers or fingers, J, corresponding in number with the levers G, and having their forward ends pivoted within said bar K in the manner shown. The fingers J have downward projecting rear ends,i,properly formed to run into and out of the openings of the musicsheet M, said points being in positions to engage with the heads G of the valve-actuating levers G when depression of the finger occurs. Springs J,arranged above the fingers J in the manner indicated, serve to press the ends 1' of said fingers J against the surfaces of the musicsheet, and to respectively depress the levers G and actuate the valves-connected therewith whenever a perforation or opening of the mtr sic-sheet M is brought beneath the end of the finger, so as to permit of its passing through and effecting action.

The finger-bar K is pivoted at its ends to suitable brackets or projections, K, fixed on the side pieces of the raceway H, the pivot,

- studs being near the forward edge of said bar to permit ofits rear edge swinging upward in the manner illustrated in Fig. 6, in order to raise the working ends 2' of the fingers J clear from the paper when rewinding the music sheet M. Flat springs K are arranged beneath the ends of the bar K for retaining it elevated, and itis held down when in horizontal position by suitable catches Z or equivalent locking devices.

My present instrument is made with a scale of thirty-two levers and series of valves, and the tube-board E has three sets of thirty-two 5 in connection with the actuating-bars I, this, i too, without materiallyincreasing the strain and wear of the parts or the pressure of the fingers upon the paper of the musicsheets.

Over the rear part of the race is arranged a suitable brace-board, O, and frame containing the stop-pulls P, provided with inclines P, for operating the rocker-wires Q, which extend to the ends of the action, where they engage the pitmen p p, which in turn actuate the levers 1 P, for transn'litting movement to the lower rocker-wires, F. These latter wires extend into the windchamber, and are provided with up ward-turned cndsf, that press against the faces of the mute valves 1* when the stops I are drawn out, and thereby raise the valves from their seats, thereby permitting the different sets of reeds R to sound according as the respective stops P are drawn. The tube-board is inclosed within a suitable compartment, of which the race-bar H forms the top, and at the front side thereof is arranged a hinged strip or swell, S, that is connected for action with the knee-lever S by the wire links and rods S S so arranged that the swell can be opened by kneepressu re when required. The movable valve-seat piece 13 is hinged to open or swing upward from the face of the tube-board E, and the swell-piecc S opens at a position in front of the same, with the removable strip t beneath it, so that by raising both the swell and the valve-seat piece and j removing the strip 25 and musicspool M convenient access may be had to any reed in the entire sets of reeds R from the front of the instrument without derangement of any other of its parts, thus permitting the ready with drawal and return of any reed that may become clogged with dust or from any cause fail to properly sound.

The winding spool or roll L is supported in suitable bearings at the back of the instrument, and said roll is provided with a thin flexible apron or connecting-piece, T, (see Fig. 1,) preferably of triangular shape, of suitable length when unwound from the roll to reach to the front of the raceway and finger-bar, and provided at its extremity with a flattened hook or stud, V, adapted to look into an opening, at, in the end of the music-sheet M, and thus establish connection between the spools M and L without the trouble or inconvenience of threading or inserting the end of the musicshect through the raceway beneath the fingers J and brace 0 every time the music is changed.

The rear edge of the apron or connectingpiece T is permanently attached to the spool L by any suitable means, and its form is such as to draw the music-sheet squarely through the race and onto the winding-spool when said spool is revolved. Said apron may be made of cloth, leather, rubber cloth, or other light gear, L, and in one of the bearings of the flexible fabric, and can, if desired, be shaped to suit the fancy or the requirements of any particular instrument.

The end of the music-sheet may he provided with a re-enforee and metal eyelet or ring at the opening m for the hook V.

"The shaft of spool L is fitted with a beveled pool is mounted asocket stud, in, carryin "beveled pinion, M This gear Land pinion M are respectively operated by means of the pinion IV and gear W fixed on the crank-shaft W, which is arranged in horizon tal position across the end of the instrument and mounted in bearings on a swinging support or frameJVipivoted in such mannerthat the shaft can be swung back and forth for meshing and unmeshing the respective gears and pinions for effecting the operation of either the music-spool M or the windingspool L. Fig. 4 shows the shaft V in position for operating the winding-spool, as when playing theinstrument, and Fig. 1 shows it in position for working the spool M, or for rewinding the music-sheet.

A suitable catch or locking device may be attached to the case or actionframe for retaining the shaft at either position of adjust ment.

The shaft V is provided with a hand-crank, X, by means of which the mechanism can be operated.

The axle-stud or journal at the right-hand end of the music-spool is made with a reduced end, 9', to fit into the socket-stud m of the driving-gear M (see Fig. 7,) where it is held from turning by a lug, n, and recess 12, so that the spool will be turned by the rotation of the gear-pinion M. The opposite journal of the spool is supported in the bearing Y, which is provided with a spring-latch, Y, that passes over the journal to hold it down to place, and with a guard, Y, for supporting thelongitudinal thrust and retaining the opposite end in the socket m. When insert ing and removing the spools M the guard Y is drawn back, allowing sufficient motion of the spool endwise to clear the reduced end 1' of axle-journal from the hollow stud m of the gear M In the operation of my improved instrument the operator sits in front of the case, places his feet on pedals B for actuating the bellows, with the right hand operates the crank X, and with the left hand manipulates the stops 1, as required. The music-spool is placed in its bearings Y, and the end of the sheet M hooked onto the flexible apron T. The shaft W is adjusted so that the pinion W and gear L intermesh with each other. Then by turning the crank the winding roll or spool L is operated to draw themusic-sheet over the raceway H, and as the perforations or openings pass beneath the ends of the fingers J said fingers are forced down by their springs J onto the heads G of the levers G, which latter are thereby actuated to open the valves I and admit air to the reeds It in accordance with the cut or perforation of the music-sheet. One or more of the sets of reeds can be made to act at a time, according as the stops are drawn for opening the mutes F, and these sets can be changed as desired while the instrument is in operation without affecting the operation of the valve meehanism. When the music-sheet is run through and wound onto the roll L, the shaft W is adjusted to intermesh the gear V with the pinion M, and the catches Z are released to raise the finger-bar K and fingers J clear of the paper. Then by turningthe crank the motion is imparted to the spool M in reverse direction, and the music-sheet is rapidly rewound upon said spool M. At the finish of the rewinding operation the end of the flexible apron or connectingband T follows through to the front, where it is in position to be detached from the present music-sheet and attached to another, the spools M" being interchanged for the various pieces as necessary.

The flexible apron T,attaehed to the winding-roll and adapted to pass through the race for attachment tothe music-sheet in a convenient manner at the front of the finger-bar or action mechanism, may be employed in mechanical musical instruments of other con struction from that herein shown with beneficial results.

I am aware that fingers working through the openings of the perforated music-sheet and engaging with devices arranged at the opposite side of the sheethave heretofore been employed in musical instruments for actuatinga valve mechanism, and I do not thereforeherein make claim, broadly, to such feature.

, hat I claim as of my invention, and desire to secure by Letters Patent, is-

1.
