' MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 245,238, dated August 2, 1881. Application filed April 22, 1581. (No model.)

To all whom it may concern:

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

My present invention relates to certain improvements in the construction and arrangement of the action devices in that class of mechanical musical instruments wherein the valves are operated by means of vibrating fingers actuatedfrom or controlled by a suitablyprepared music-sheet passed in contact with their ends; the objects of my invention being, first, to provide a finger device which will run with light touch and without injuring the perforated music-sheet; second, to provide avalve mechanism sensitive, quick, and easy of operation; third, to afford facilities for raising the fingers when reversing the movement of the music-sheet; fourth, to afford a simple and convenient means for relieving and raising the presser-roll from the music-sheet; fifth, the improvement of the bellows and feeder mechanism, and their arrangement within the instrument with constructive convenience and efficiency. I attain these objects by the mechanism herein illustrated and described, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure l is a rear view of a mechanical musical instrument embracing my improvements. Fig. 2 is a part front, part sectional, view of the same. Fig. 3 is a vertical sectional view at line a: m, Fig. 1. Fig. 4 is a part top plan, part horizontal, section at line y y, Fi 3. Figs. 5, (3, and 7 are detail sectional views on larger scale, showing the parts in different positions of their action; and Fig. 8 is a bottom view of one of the fingerlevers and its spring.

The outside casings and devices for rolling up the music-sheet are not herein shown. Such parts may be of ordinary or any suitable construction.

A denotes the end frames, with air-passages a; and B indicates the wind-chest, its inner chamber communicating with said passages.

0 indicates the reed-cells, provided with reeds G and with inlet-openings 0, all of which may be substantially as heretofore constructed.

1) indicates the raceway or table for supporting and guiding the perforated musicsheet M as it passes through the instrument. Said table D is located at a short distance below the wind-chest B, and is rigidly held in position between the side frames, A, its ends being let into grooves formed horizontally across the inner sides of the end frames, A.

E indicates the fecd-roller for moving forward the music-sheet, said roll being arranged at the rear edge of the table 1D for operation in the usual manner.

F denotes the presserroll, for holding the music-sheet in contact with the fecd-roll E. This presser-roll F is mounted in bearings F, which are arranged to slide up and down in the guides or brackets G, said bearings being connected with each other by a bar, F, the central part of which is suspended or supported at a fixed position by means of a strap, bracket, or other suitable device, as at f, and at a height sufficient to raise the roll F clear from the sheet M when the depressing force is removed from the bearings F.

H denotes the pressure-levers, for forcing the roll F against the feed-roll. Said lovers are formed of wire or other suitable material, fulcrumed or pivoted through the coil or angle at h, with their lower arms resting upon the bearings F, while their upper arms engage with the crank-arms J on a rocker-shaft, J,

arranged across the upper part of instrument,

as illustrated. When said arms J are turned down, as in Fig. 3, thelevers H will press down the bearings F, springing the bar I, so as to setthe roll Ffirmly down upon the music-sheet M, for assisting the feed-roll E in moving it forward, and when the arms J are turned up, as in Fig. 7, the strain on levers His removed, and the spring-action of the bar F relieves the pressure on the roll F and raises said roll clear of the music-sheet, as indicated in Fig.7, and by dotted lines in Fig. 1.

I indicates the vibrating fingers or levers, for operating the valves K, which admit air to the reeds. Said levers I are made in the form shown, and consist of a foot-piece, I, pivoted at or near the heel, as at l, to the support-bar L, and the upward-projeetin g arm or wire 1 fixed in the rear end of said foot-piece I, and forming therewith an an gle-lever. The front end of the part I is made with an under rounded curve, i, and offset 0, forming a hook orrider, m, which runs on the m usic-sheet and drops through the perforations thereof as they pass beneath it. The fingers or levers I are arranged with their rider ends on forward of their pivots Z, or standing in the direction from which the music-sheetis drawn, and arein full clear view in front of wind-chest, instead of heneath it.

The valve K, I arrange to operate in the manner indicated, the valve being hinged at a to swing upward, as shown, and to act as a clapper over the aperture 0. The top of the valve-block is connected with the end of the vibrating finger or lever I by means of a flexible attachment, K, which is of such length that it can loop or buckle when the valve K is closed, the movement of the lever I being slightly greater than the swing of the valve K, so that the straightening of the flexible attachment will snap or jerk the valve from its seat with a quick rolling action, thereby overcoming any tendency to stick down by reason of the suction of the bellows, and rendering the action easy, sharp, and positive, while the touch of the fingers I on the music-sheet is light and sensitive.

Figs. 3 and 5 show the valve K closed, and Fig. 6 shows the valve as drawn open by the dropping of the finger I. In Figs. 1 and 2 Valves are shown open at K". In the present instance the valve K is of triangular form, and is connected by a strap to an angle-lever, I. I do not desire, however, to confine myself to those particular forms, as other forms may be used without departure from the nature of my invention, the essential features of which are a rolling or hinged valve, an actuating-lever or its equivalent, and a flexible connection capable of buckling or having slaekness when the valve is closed.

The levers I and valve K are arranged in regular series, as indicated, the levers being pivoted in slots formed in the supporting-bar L, which extends across the lower front part of the wind-eh est B, and also forms a top guide for the music-sheet, causing it to run close to the surface of the table D. Depressions d are formed in said surface to permit action of the finger ends m.

Small springs P are arranged in connection with the fingers I for pressing them down and actuating the valves. Said springs are arranged to act on the heels of the levers, (see Figs. 5 to 8,) and can be made very light, as the construction and arrangement of the valves and levers are such that they operate with ease and require but little assistance from the springs. The proportional balance between the spring and rider-point m is such that said point bears very lightly on the perforated music-sheet, and thus avoids the liability of tearin g out the paper between the perforations.

t indicates a swinging bar for raising all of the fingers I from off the paper when reversing or rewinding the musie'sheet M. Said bar has its ends It extending upward and forward near the side frames, A, so as to work in connection with the crank-arms J of the rockshaft J, and said parts R are so pivoted or fulcrumed at R that when the arms J are turned upward the bar It will swing forward, as illus trated in Fig. 7, and raise all of the levers I in the manner shown. The bar It and the levers II are both operated sin'mltaneously for relieving the presser-roll F and raising the fingers I by turning the shaft J by its thumbpiece J which may be located at the exterior of the casing.

S indicates the feeder-board or bellows-feed ers support. Said board is fixed in horizontal position between the side frames, A, and is provided with air-passages S, leading from the side passages, to, to the bellows T, which are arranged in upright position at the front part of the instrument, and with passages S", leading back from the bellows into the board, and cominunieatin g through suitable valved openings, 8, with the feeders V, that are arranged upon the top and bottom of the feeder-board S, in the manner shown. The upper and lower feeders are connected to operatein unison by a rod, V, so that one is filling while the other is exhausting, and both receive their motion from the crank-shaft W by pitmen W, in the manner indicated, said crank-shaft IV being geared to the music-feed shaft IQ, and operated in the ordinary manner by the crank E, orin any other suitable way. The feeders V are provided with valves 4;, arranged as indicated, and act to exhaust the airin the bellows T, which draws the air from the wind-chest B by way of the passages a and a, the course being indicated by the arrows. This peculiar construction oi the feeder-board S, and the arrangement therewith of the bellows T and feeders V, in the manner shown, forms a very compact, simple, and efficient apparatus, giving great windpower with economy of space, ease of operation, and cheapness of manufacture.

L indicates a buffer-strip, of wood and felt, let into the support-bar L to serve as a stop to the forward throw of the valve-actuating levers l.

Thedirectionin which themusic-sheet passes through the instrument when playing is indi cated by the arrows in Fi 3.
