MECHANICAL MUSJCAL- INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 321,738, dated July 7, 1885.

Application filed November 27, 1883.

To all whom it may concern:

Be it known that I, JOHN MoTAnMANY, a citizen of the United States, residing at WVorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Automatic Musical Instruments; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

15, This invention relates to automatic musical instruments which are operated by perforated music-sheets, and is an improvement on the instrument shown in my Patent No. 290,697, granted December 25, 1883, the application for which was filed March 6, 1879. In that patent two treadles are shown, one of which operates the bellows, while the other winds, by pawl and ratchet, a spring which gives rotary motion to the winding-roll for the musicsheet. In the present improvement I still use two treadles, as well as the other parts above mentioned; but both of them operate the bellows and both of them wind the spring which rotates the winding-roll, the said treadles acting alternately, whereby an approximatelycontinuous action is produced.

My present invention consists partly in the combination, with the aforesaid devices, of two disks on the shaft of the winding-roll, and

having a pawl-and-ratchet connection therewith, and a drum arranged to engage with and turn said winding-roll, said spring being attached at one end to the shaft and at the other to the said drum, each cord being carried over 0 one of said disks and then down to one of said feeder or pump bellows, in order that the operation may be as stated.

The said invention also consists in a winding music-roll having a radial stud or projec- 5 tion, in combination with a spring-operated drum and a bar or plate, which is carried by said drum, and adjustable at will to extend beyond the periphery thereof for the purpose of engaging with said stud.

The said invention also consists in a wind.-

ing-roll at one end of an automatic musical instrument, in combination with a disk of larger diameter, having a radial stud, in combination with a spring-operated drum provided on its periphery with a slotted bar or plate, which is movable longitudinally, so that it may be in or out of position for contact with said stud.

The said invention also consists in an automatic musical instrument having a rewinding roll-shaft in two sections, one of said sections being fixed in a frame and the other being attached to the rewindingroll, said sections being provided at their proximate ends with disks, which are united to one another by a 6" tongue-and-groove joint, whereby the rewinding-roll and the shaftsection attached thereto are left free to be removed.

It also consists of a rack, which is provided with two upper feed-rolls or pressure-rolls, which bear against the lower feed-roll or feedroll proper, in addition to the pressure-roll which holds the sheet in proximity to the reedducts.

It also consists in the combination of the lower feedroll with two upper feed-rolls, one of which is in the same vertical plane with the axis of the rack which carries it and the other is in advance of that plane, these posi tions being held when the rack and the rolls attached thereto are in position for the ma chine to operate.

The invention also consists in additional improvements hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a vertical section from front to rear, taken through an instrument embodying my invention at the side where the operatinggearing is located, some of the supports and gearing being removed and the wind-chest being shown in section to more clearly illustrate the interior construction of the instrument. Fig. 2 represents a front View of the same with the front of the case removed. Fig. 5 3 represents a plan view of the machine with the top of the case removed. Fig. 4 represents a detail view of the interior of the drum and the spring contained therein. Fig. 5 represents a detail view of the shaft of the re- 10o winding-roll Fig. 6 represents a detail perspective view, taken from below, of the rack and the rolls attached thereto. Fig. 7 represents a vertical section through the rack, the rolls attached thereto, and the lower feed-roll. Fig. 8 represents a detail view of the bearings for the pivot or gudgeon on one side of the rack and the bracket which supports them.

A designates the case of the instrument, in the lower part of which the usual reservoirbellows, B,and the two feeder or pump bellows, B B are located. These feeder-bellows are operated alternately by means of cords O C", which are attached at one end to each of said bellows, respective] y, and at the other end to two treadles, 0, one cord to each treadle. These trcadles extend through the front of the case at the bottom thereof, and are arranged side by side, as usual, so that the feet of the performer will operate alternately with convenience. Each cord passes up and over a pulley, D, which is loose on the shaftof the wind ing-roll, each end of said winding-roll being provided with one of said pulleys; thence said cord passes down through an opening, 0,

in a horizontal partition, E, and around a guide-pulley, F, which turns in bearings attached to the under side of said partition,and thence to its fe der-bellows, as stated. Each cord, its pulh and the opening through which it passes are the counterparts of the corresponding contrivanees at the other side of the instrument. The partition E divides the instrument into an upper and a lower part. On said partition is supported the wind-chest F, which has communication by means of an opening, f, in said partition with the reservoirbellows B, and communicatesthrough an opening or openings,f, (indicated by dotted lines in Fig. 1,) with the reed-ducts in the reed-board G above said wind-chest. Over the top of this reed-board the music-sheet H passes from right to left. As the openings in said musicsheet allow the passage of air through the reeds under the draft or impulsion of the bellows in the usual and well-known manner, the production of music by said instrument is controlled by said music-sheet. Each pulley D carries a pawl, d, which is arranged to engage a ratchet-wheel, I, fast on the shaft of the winding-roll, when said pulley D is turned forward. The two ratchet-wheels 1, arranged, respectively, beside said pulleys, are fast upon the winding-roll shalt J, on which the winding-roll K is loosely sleeved. This roll has at each end a disk, 70, and in contact with the outer face of one of said disks is arranged a hollow drum, L, having a detachable attachment to said disk-01, more exactly, contact devices-hcreinafter to be described,whereby, when said devices are in proper position the forward rotary motion of said drum is communicated to said disk and winding roll. lVithin said drum is a clock-spring, M, hav- 3 ing one end attached to said shaft and the other end to the interior of the drum.

The operation of the treadles, pulleys, pawls,

and ratchet-wheels above described is to continuously wind this spring, which exerts at its outer end a corresponding regular action in rotating the drum and winding-roll. Each pulley, pawl, and cord is replaced after each pressure on the treadle by the action of a spring, V, on its bellows B or B. To make this action still more regular I provide a regulatingfan, N, which is operated from a gearwheel, 0, carried by said drum, through the medium of gear-wheels 0 O on a supplemental shaft and pinion, a, on the shaft of said fan. The latter acts as a fly-wheel, regulating by its momentum the rotation of the windingroll. After the music-sheet has been entirely wound upon the said roll the operation of rewinding to withdraw it therefrom and wind it on the rewinding-roll ordinarily becomes necessary. This requires the winding-roll to turn freely backward. To provide for such backward rotation I have made use of the contact devices hereinbefore referred to, which con sist of a stud, 7o, projecting radially from one of the disks 7c, and a slotted bar or plate, L, which is secured to said drum L by screws passing through the slot in said bar, which allow the latter to be moved laterally in or out, as desired. \Vhen said bar is in its extreme position in one direction, it will come into contact with said stud 7a and turn the disk k and the winding-roll, as stated; but when said bar is withdrawn so as not to come into contact with the said stud the rotation of shaft J will not be communicated to said winding roll, and, further, the latter will be quite free to be turned backward, allowing the musicsheet to be drawn rapidly and without strain from said roll.

K designates the rewinding-roll on which the music-sheet is wound under the circumstances last stated, and from which it is drawn by the winding-roll K during the normal operation of the instrument. This rewindingroll receives its rewinding motion from the winding-roll through the gear-wheels O O 0*, before mentioned, a pulley, 0, carried by O", and an endless belt or chain, 1 which passes around said pulley, and also around a pulley, q, on the shaft of said rewinding-roll. This latter pulley is normally loose on said shaft, leaving the rewinding-roll K free to be drawn forward by the draft of the winding-roll on the musicsheet; but when rewinding is to take place the said pulley q is locked to said rewinding-roll shaft by a clutch, 1, which is splined on said shaft and adapted to be moved into engagement with a suitably-formed drum, q, 011 which said pulley is formed, or to which it is permanently attached.

The rewinding-roll shaft aforesaid consists of two sections, one (which carries said clutch and pulley) being stationary and journaledin bearings supported on the partition E. The other section is short and directly connected to the rewinding-roll. The contiguous ends of these sections are provided with disks Q. Q", one of which has a tenon or rib, r", ex-

llO

tending diametrically across its face, while the other has a groove or mortise, (f, of corresponding shape and arrangement. By reason of the engagement of this tenon or rib and this mortise or groove the two sections of the shaft rotate together; but the rewindingroll K may readily be withdrawn from the machine by turning its shaft until said rib and groove are vertical, and then lifting said rewinding-roll. This removal is often convenient for the substitution of one musicsheet for another. As the top of the reedboard is higher than the winding and rewinding rolls the draft of the winding-roll upon the musicsheet and the inevitable slight frictional resistance of the rewinding-roll will usually keep the music-sheet against the mouths of the reed-ducts, and no additional holding or feeding devices are absolutely required. I have, however, found it best in some instances to use additional feeding and holding devices of the following construction:

R designates the lower feed-roll or feed-roll proper, which turns in bearings attached to the reedboard, and is driven by gear-wheel O and a gear-wheel, r, meshing therewith, on the shaft of said lower feed-roll.

S designates the rack, which is pivoted by gudgeons s to the case of the machine or bearings attached to said case. The forward part of this rack is provided on its under side with brackets s, that serve as bearings for the pressure-roll S, that bears against the forward edge of the reed-board and holds the musicsheet against the same. The rear part of said rack is provided with two flexible bearingplates, S, attached to the under side thereof, which serve as bearings for two parallel upper feed-rolls, T T, springs i being interposed between these plates, respectively, and the under face of said rack, and serving to hold these latter rolls in place against the music-sheet 011 each side of the center of the lower feed-roll. Then in position for the instrument to operate, the axial line of the rear roll, T, as shown in Fig. 1, is directly under (that is,in the same vertical plane with) the axial line of the rack, which passes through gudgeous s, aforesaid. As the music sheet is drawn forward between the lower feed-roll and this smaller roll T, arranged obliquely above it and behind it, as shown in Fig. 1, the oblique upward and backward strain of said music-sheet on the lastnamed roll will tend to turn said rack forward and downward on its axis, thus holding the pressure-roll S against the forward edge of the reed-board or any other convenient part thereof. The springs t have no effect in bringing this result about. The roll T, parallel to T, holds the music-sheet against the lower feed-roll on the other side of the center thereof, and insures accuracy of operation. The oblique upward and backward strain above re ferred to is caused by the upward and forward travel of the music-sheet in an inclined path, as shown in Fig. 1, and by the position of the rear roll, T, obliquely above and behind the feed-roll It. As the sheet moves between said rolls It and T the motion of said sheet inevitably exerts an upward and rearward pressure against said roll T in the direction of a line drawn from the point of contact to the axis of said roll-that is to say, very nearly in a line drawn from the axis of roll R to the axis of roll T. \Vhen the musiesheet is drawn backward, as in rewinding, it tends to raise the rack by its backward and upward draft on the roll T, so that there will be no obstruction to rewinding and no injury to the paper.

The bearings for the pivots of the rack are formed by plates arranged in pairs, the upper plate, 1 in each instance, having a curved end, which is raised to allow the pivot or gudgeon to be inserted below the curvature, while the lower plate, Z, is a spring, and bears upward to close the neck of the latter. By raising the rack to a vertical position, Fig. 8, and then pressing it down so that the pintles, pivots, or gudgeons will force the said lower spring-plate away from the upper plate, Iam enabled to easily remove the rack.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
