MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 567,079, dated September 1, 1896. Application filed November 23, 1895. Serial No. 569,927. (No model.)

and State of New York, have invented a new and Improved Musical Instrument, of which the following is a full, clear, and exact description. V v

This invention relates to certain improvements in musical instruments, and especially that class of such instruments as are adapted for automatic playing, being actuated by a strip of paper fed over a barrel and provided with perforations adapted to coincide with ducts formed in. the barrel, so as to bring into operation the different reeds; and the object of the invention is to provide a device of this character of a simple and inexpensive nature which shall be adapted for repeating airs or portions thereof indefinitely, and provided with means for feeding the perforated paper sheet in a substantially uniform and continuous manner.

The invention consists, in part, in a musical instrument of this character having a barrel provided with two sets or series of ducts leadin g to a common series or set of reeds or equivalent devices for playing, a valve for placing one or the other of said series of ducts out of action while the other series or set is in use, a musicsheet having two series of apertures, mechanism to move the music-sheet in opposite directions, and means actuated from the music-sheet-moving mechanism for reversing the piston of the valve when the movement of the music-sheet is reversed, and, in part, in certain improvements in the strip of paper employed for actuating the reeds or equivalent devices, whereby one side or one half of said strip is provided with perforations adapted to control one series or set of ducts in the barrel and the other side or half of said sheet is provided with similar perforations arranged to control the other set or series of ducts in the barrel.

The invention also contemplates certain novel features of the construction, combination, and arrangement of the various parts of the improved musical instrument, whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use than various other similar devices heretofore employed, all as will be hereinafter set forth. The novel features of the invention will be carefully defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters 'of reference indicate corresponding parts in all the views.

Figure 1 is an end view of the instrument, the casing being removed, so as to show the various operating parts. Fig. 2 is a similar view of the opposite end of the instrument. Fig. 3 is a sectional view taken longitudinally through the barrel of the instrument in the plane indicated by the lineooosin Fig. 6. Fig. 4 is a somewhat similar view taken in the plane indicated by the lineyy in Fig. 6. Fig. 5 is a fragmentary detail view showing certain of the operating parts of the instrument to be hereinafter referred to. Fig. 6 is a section taken transversely through theinstrument in the plane indicated by the line zzin Fig. 7. Fig; 7 is a fragmentary plan view showing one end of the barrel of the instrument, the face-plate thereof being broken away to show the construction of the underlying parts; and Fig. 8 is a view drawn to a small scale and showing a fragment or section of the m usic-sheet.

In the views, 1 indicates the base of the instrument, wherein is mounted a bellows (not shown) in the usual way, and on said base, at one end of the same, is arranged a standard 2, in the upper end of which is journaled a short shaft 3, provided with a crank 4, adapted to be turned by the hand in playing, and said shaft is also provided with a spur-wheel 5, meshing with a pinion 6, also journaled on a stud 7 on the standard 2, and meshing with a large spur-wheel 8, mounted on a shaft 9, extending longitudinally on the base 1, along one side thereof, being journaled at its ends in standards 10, as clearly seen in the drawings. On the extremity of the shaft 9, adjacent to the spur-gear 8, is fixed a pulley 11, over which passes a belt 12, crossed at its central portion and arranged to pass around a similar pulley 13, fixed on the end of a shaft 14, extending longitudinally along the opposite side of the base 1 and journaled at its ends in standards 15 on said base.

IOO

On. the respective shafts 9 and 1% are mounted pinions 16 and 17, arranged to mesh with spur-

wheels

18 and 19, mounted, respectively, on

shafts

20 and 21, journaled in the lower ends of vertical arms 22, formed on opposite extremities of the end bars of a frame 23, secured by means of screws 21 to a rockin g frame comprising end pieces 25, connected by side bars 25, extending longitudinally of the base, said rocking frame being provided at opposite ends with short pivots or trunnions 26, mounted to turn in bearings in the upper ends of standards 27 at opposite ends of the central portion of the base 1.

At the upper ends of the arms 22 of the frame 23 are journaled

reels

28 and 29, respectively, extending longitudinally of the instrument and adapted to receive upon them the music-sheet 30, consisting of a strip of paper having its opposite ends secured in any way to said reels and adapted to be wound upon one and simultaneously wound off the other, the central portion of the said strip between said reels being carried down, as seen in the sectional view Fig. 6, around

rollers

31 and 32, fixed on. the

shafts

20 and 21, respeetively, and also extending longitudinally of the instrument, between which rollers the said music-sheet is carried up, as seen in Fig. 6, over a face-plate of the barrel 33 of the instrument, which face-plate is provided at opposite ends with raised shoulders 3%, forming guides to prevent movement of said music-sheet laterally or endwise of said barrel.

On the ends of the

respective shafts

20 and 21 opposite to the end of the instrument at which-the

pulleys

11 and 13 are located are fixed small pulleys and 36, and on the ad jaeent ends of the spindles or shafts of the

reels

28 and 29 are fixed similar pulleys 37 and 38, respectively, and over the said pulleys, at the upper and lower ends of the respective vertical arms 22 of the frame 23, are arranged to pass

belts

39 and 40.

On the respective shafts 9 and 11 are mounted

rollers

31 and 32", arranged under the

respective rollers

31 and 32 on the frame 23, and the respective rollers 31 31 and 32 32 at opposite sides of the instrument are adapted to engage opposite sides of the music-sheet when the frame 23 is rocked, so as to feed said sheet from one reel to the other, the pinions 16 and 18 being in engagement to wind the sheet from the reel 29 onto the reel 28 when the said frame 23 is rocked or tilted to the position seen in the drawings, the pinions 17 and 19 being at this time out of engagement, and these last-named pinions 17 and 19 are adapted to be engaged when the frame 23 is rocked in the opposite direction, so as to wind the sheet of paper off the reel 28 and 011 the reel 29.

On the ends of the

respective shafts

20 and 21, at the lower ends of the arms 22 of the frame 23, are fixed pulleys 41 and i2, respectivel y, over which pulleys passes an endless belt or band 43, connecting said pulleys, so that the

shafts

20 and 21 are caused to turn in unison, whereby it will be seen that when. the gear-wheels 1G and 18 are engaged to drive the shaft 20 from the shaft 9 the shaft 21 is also driven, and when the gear-wheels 17 and 19 are engaged so as to drive the shaft 21 from the shaft 11 the shaft 20 will be driven, but in a direction opposite to that in which it was before driven.

At the end of the instrument opposite to the crank i is arranged a crank 11-, adapted to be operated by hand, and having a square socket fitting the squared end 15 of a screw 46, collared in the standard 27 at one end of the instrument, as clearly indicated in Fig. 3, and engaging a nut 47 in the adjacent end piece 48 of a slide comprising two side bars 4.9, mounted in guides 50, arranged on opposite sides of the barrel of the instrument, the construction being such that when said screw v 4.6 is turned by means of the crank it said side bars 19 are caused to move longitudinally of the barrel, which barrel extends alon the central portion of the instrument, as clearly seen in Figs. 1. and 2, wherein said barrel is indicated by the reference-charaeter 33*. On the end bar 1-8 of the slide is mounted an up right linger 51, to which is pivoted at 52, as clearly seen in Fig. 7, one arm of an elbowlever 53, fulcrumed at 5t on the bracket 27 and arranged to play in a horizontal plane, the opposite end of said lever being arranged to engage a recess at the central part of a slide-bar 56, having slots formed in it and engaged by guide-pins 57 on one end of the frame 23, as clearly seen in Fig. At its opposite ends the slide bar 50 is provided with clutch shoes or surfaces and 58, projecting from it and arranged, respectively, between the opposite strands of the respective bands or belts 39 and -10, and said slide-bar also carries, adjacent to its opposite ends, rollers or

pulleys

59 and 59, arranged, as seen in Fig. 2, upon the sides of the inner strands of the respective bands 39 and 49,011- posite to the clutch shoes or surfaces 58 and 58. The ends of the frame 23 are also provided with clutch shoes or surfaces 60 and (50, projecting from them above the rollers or

pulleys

59 and 59. By this construction it will be seen that when the slide-bar 56 is moved to the left, as indicated in Fig. 2, the pulley or roller 59 will be caused to engage the band or belt 39, so as to tighten the same about the pulleys 37 and 35 and prevent slipping of the band, and at the same time the band -I-() is engaged between the clutch-shoes 58 and 60 at the opposite end of the frame 23 and securely held against movement, whereby it will be seen that the shaft 9, the gear 19 on which is at this time in engagement with the gear 18 on the shaft 20 in the position of the parts shown, will communicate its movement to the reel 28, so as to wind the music-sheet thereon, the reel 29, from, which the music sheet is being unwound, being at this time held against too free movement.

On the side bars 4L9 are arranged wedgeshaped cams or

projections

61 and 61, respectively, the inclined faces of which are oppositely directed and are adapted to engage spring-dogs 62 and 62, pivotally mounted in

brackets

63 and 63" on opposite sides .of the barrel 33 of the instrument and normally held in an upwardly-pressed position, as will be readily understood, by means of

springs

64 and 64, connected to them and engaging the lower portions of said brackets, the heads of said dogs 62 and 62 being arranged in position to engage the under sides of the depending lugs or projections 65 and 65, centrally located on the side bars 25 of the rocking frame 25 above mentioned. As shown in the drawings, the lug 65 is shorter than the lug 65, for the reason that the dog 62 is arranged upon the reed-board of the instrument, and consequently is higher up than the dog 62.

At the ends of the side bars 49, adjacent to the actuating-screw 46 thereof, are arranged upwardly-extending arms 66, the upper ends of which are connected to horizontal brackets 67, in the bent ends of which are pivoted the opposite ends of a shaft or pintle 68, to which is connected the end of the sliding valve 69 of the instrument, which, as will be clearly understood by inspection of Figs. 3, 6, and 7, plays longitudinally of the barrel 33, being arranged in a space 70, formed between the upper face of said barrel and the faceplate 33 thereof.

In the face-plate 33 of the barrel 33 are formed two sets of openings 71 and 71, alined with each other and extending along the central portion of said face-plate, one set being arranged at each end of said face-plate and occupying one-half of the length thereof, and the lower ends of alternate openings in the said series are carried in opposite directions, as clearly seen at 72 in dotted lines in Figs. 6 and 7, in a position to coincide with the openings formed in the sliding valve 69. The said openings in the sliding valve 69 are formed in two sets, one set being arranged at each end of the said valve, corresponding in position to the two series of openings 71 and 71 in the face-plate of the barrel, and each set of openings in the said valve 69 is formed in two rows, the set in the left-hand end in Figs. 3 and 4 being formed in rows 73 and 7 3, arranged along opposite sides of said valve, the openings 7 3 being between the openings 73 in position to coincide with the oppositely-directed lower ends 72 of the openings 71 at the left-hand end of the face-plate of the barrel 33, and the openings 74 at the right-hand end of said valve are similarly divided into two series correspondingly arranged with respect to the lower ends of the openings 71 at the right-hand end of the faceplate 33.

In the barrel 33 are formed ducts to communicate with the openings in the face-plate. These ducts are also divided into two sets, each set being divided into two rows, the

two rows of ducts at the left-hand end of the barrel, as shown in the drawings, being numbered 75 and 7 5, respectively,while the rows of ducts at the right-hand end of the barrel are numbered 76 and 7 6. The

respective rows

75, 75, 76, and 76 are arranged in different vertical planes, as clearly indicated in Fig. 6, the upper ends of the rows 75 and 76 being alined longitudinally of the barrel, to effect which the upper ends of the ducts 76 are bent somewhat laterally, as will be readily understood, so that the said ducts '75 and 76 are arranged to correspond with the rows of openings 73 and 74, extending along one side of the sliding valve 69. The rows 75 and 7 6 are similarly alined at their upper ends along the opposite side of the barrel 33 in position to coincide with the openings along the opposite side of said valve 69. The lower ends of these ducts communicate with openings formed in the upper parts of pneumatic keys 77, each of which is constructed in an elongated form, as seen in Fig. 6, with flexible side walls 78, the under sides of said keys bein g provided with vents 79, of less area thanthe openings through which the ducts communicate with the said keys, and each key is held normally in a collapsed condition by engagement of a pin or stud 80, held on a reedvalve 81, suitably located below the base 1 of the instrument, and normally pressed upward by means of a spring 82 in position to close the flow of air through the corresponding reed 83 in the reed-board.

The pneumatic keys and valves are ar ranged in the vacuum-chest of the instrument, and air is exhausted from said chest by means of the bellows, (not shown,) these being of the usual construction, and by this arrangement it will be seen that the bellows will exhaust the air from the pneumatic keys, but that when a perforation in the musicsheet registers with one of the ducts in the barrel which is not closed by the valve the air will be drawn through said duct into the key, so as to inflate the same and move the valve 81 against the force of its spring, so as to sound the reed. Whenthe crank 44 is turned, the screw 46 thereon will serve to slide the side bars 49 of the slide endwise, carrying with them the valve 69, the position of which willbe reversed, so as to open the series of ducts in the barrel which were before closed, and when the slide is moved endwise it will be seen that by reason of the engagement of the pin 52 with the elbow-lever 53 the slide-bar 56 will be moved endwise, so as Y to disengage the clutch members from one of the straps 39 40 and engage the other clutch members with the other of said straps 39 40. At the same time, the cams 61 61 being secured to the side bars 49 of the slide, it will be evident that one of said cams will be caused to ride up on one of the dogs 62 62, while the other cam will be moved in the opposite direction. In this way the rocking frame will be tilted, so that the position of IIO the gearing at opposite ends thereof will be reversed and the reel which was before actuated will not be driven and the reel which was not before actuated will bedriven, but in such a way as to cause the music-sheet to move in a direction opposite to that in which it moved before.

As shown in Figs. 3 and 4;, there are twenty of the pneumatic keys 77 in the instrument, and consequently there will be twenty reeds in the reed-board, one controlled by each key, although a greater or less number of reeds may be used, as will be apparent, and each set or series of ducts in the barrel and of openings in the sliding valve 69 and in the face-plate of the barrel comprises twenty ducts or openings, corresponding to the respective reeds and pneumatic keys. For example, referring to Fig. at, the pneumatic key 8 at the left-hand end of the barrel 33 communicates by way of a duct 75, as shown at c in said figure, with the first opening in the row of openings 7 3 at the left-hand end of the sliding valve 69 and with the corresponding perforation or opening 71 at the lefthand end of the face-plate of the barrel, and said key c also communicates with the lower end of the duct extending up, as indicated at c in Fig. 4:, and arranged to communicate with the first opening of the series of openings 74 at the right-hand end of the sliding valve 60 and with the corresponding opening 71 in the face-plate of the barrel.

The openings in the sliding valve 69 are so arranged that when said valve is slid in one direction, for example, so as to stand in the position shown in Fl 3 and 7, the set or series of ducts 7 5 and 7 5 at the left-hand end of the barrel will be placed in communication with the openings 71 at the left-hand end of the face-plate while the set or series of openings 7 (5 and 7 6 at the righthand end of the barrel may be cut off from communication with the openings 71 at the right-hand end of the face-plate, and the pneumatic keys 77, connected to said last-named series of ducts 7G and 76, will be prevented from operating, by reason of the supply of air through said ducts being cut off. Consequently only the ducts 75 and 7 5 will serve to convey air to said pneumatic keys to operate the reeds. When the sliding valve 69 is moved in the opposite direction, this condition is reversed, and the ducts 7 6 and 76 serve to convey air to said keys 7 7 while the supply of air to the ducts 75 and 75 is completely cut oil.

The strip of paper or music-sheet employed in connection with the instrument constructed as above described is shown in Fig. 8, and consists of a sheet having its opposite sides divided into longitudinal spaces corresponding to the several notes, each side being formed with a number of notes corresponding to the full number of notes in the reed-board of the instrument. As shown in said Fig. 8,

the strip 30 is made of a width corresponding to the length of the face-plate 33 of the barrel and is divided into two halves a a, one half corresponding to each set or series of openings 71 and 71 in the said face-platcg and to control the flow of air through the ducts in the barrel and the openings in the face-plate thereof said strip 30 is provided with perforations suitably arranged, as clearly shown. By this arrangement it will be seen that when either one of the perforations in the side a of the sheet 30 (premising that this side of said sheet is arranged to pass over the left-hand end of the face-plate 33, as seen in Fig. 3) comes to be over the corresponding opening in said face-plate, air will be drawn by the bellows (not shown) through the corresponding duct at the left-hand end of the barrel, thereby causing the pneumatic key to expand and open the corresponding reed S3 in the reed-board, so as to sound the same.

For convenience in repeating the airs or parts thereof contained on the music-sheet 30 I prefer to arrange one part of the air upon one side of said strip, for example, upon the side a, and the remaining portion thereof upon the other side, a, of the strip. When this arrangementis followed, the crank at will be turned so as to wind the strip 30 over the face-plate 33 in one direction, for example, as indicated by the arrow 6 in Fig. 8, until one-half of the air has been played, whereupon the crank at is manipulated so as to shift the driving mechanism of the strip 30, and simultaneouslyto shift the sliding valve 69, so as to bring the

ducts

76 and 76 at the opposite side of the barrel into operation, whereupon the strip 30 will move in the direction indicated by the arrow 6' in Fig. 8, and the perforations in the side a of the said strip will serve to control the flow of air to the said ducts 7 6 and 7 6, so as to play the remainder of the air. \Vhen the end of the tune has been reached, it will be evident that the crank 4* maybe manipulated so as to return the parts to their original positions, whereupon the first portion of the air will be again played, and this operation may be continued indefinitely.

By the construction of the device as above described it will be seen that the music-strip is fed evenly and uniformly through the instrument by being engaged between the respective rolls 31 31 and 32 32, and the music-sheet being made in the form of a strip may be of indefinite length, while at the same time any air or portion of an air may be conveniently repeated without changing said strip.

It will also be obvious from the above description that the device is susceptible of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the exact form of the device herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
