K K are cups riveted to the ends of the shafts A A D D.

K is a spring on one end of the shaft A.

K are lock-nuts.

K is a pinin the cup K for turning the tube roller E.

The operation is as follows: The springmotor being wound up in the usual way, the pin-cylinder is raised up out of operative position relative to the spur-wheels B by lifting the lever G, Fig. l-i. The musie-roller is placed in position on the cup K by drawing the thumb-nut D back against the spring K. The end of the sheet D with the arrow to the left, is passed over and under the pres sure-roller A", the roller being raised by the lever A". The first holes in the marginal lines of the feed-holes in the sheet commencing at the bottom are indicated by letter a. By placing these holes a on the feed-pins I) in the cylinder A, and allowing the pressurerollerA to rest upon the sheet, all the other holes in the marginal lines marked a will be brought on the feed-pins in the cylinder marked If, by reason of the equal distance apart of the marginal holes a and the pins The lever d is now raised, the arm I) is lifted out of engagement with the pin I) in the wheel B. By lifting the lever (Z the cylinder is turned by the motor and the sheet passes around the cylinder, being guarded by the guides A until it arrives under the roller 17. The deflecting-guide A will cause the sheet to pass between it and the roller 17. It is then secured to the take-up roller, which is placed in position the same as the musicsheet roller, the end of the sheet being inserted in the longitudinal slot and turned around once or twice.

The end of the music-sheet for some distance has only marginal feed holes, the part of the sheet between the feed-holes be ing left blank or without music-holes until the sheet is fully placed. in the instrument.

The instrument is now ready to be set in operation. The lever (Z being raised, a hole Z) in the sheet D will permit the passage of a movable pin Z), which will move the spurwheel Bone tooth; the cam 13*, being fixed to the spur-wheel B, moves with it, moving the arm 0 and will bring a blank part of the cam B opposite the end of the arm b against which it will rest, thus raising the arm 11" out of engagement with the pin Z) in the wheel B and permitting the movement to go on to the end of the sheet, when another hole I), on the same line in rear end of the sheet, will permit the passage of a pin l), which will again move the spur-wheel B and cam B and bring a notch b opposite the end of the arm U, into which it drops, and engaging the arm b with the pin b in the wheel and stopping the movement. One of the pieces of music is now played to the end and the inStrument automatically stopped. The cylinder is again raised out of operative relation 7 with the spur-wheels B by the lever G. The

lever d is lifted and held up, the pin (1 raising (1 and its connection d disengaging the arm 19 from the pin 1)". The movement again commences unwinding the remainder of the music-sheet from the music-roll to the takeup roll. The perforated music-sheet is now wholly on the take-up roll, and is taken out and placed between the flanges A A, with the arrow to the left, when it is again passed around the cylinder, as before. The first of the marginal holes now on the end of the sheet are marked 12, and these holes I; placed on the feed-pins being also equidistant with the feed-pins b will cause another and different set of music-holes in the sheet to register with the movable pins in the cylinder. These holes may play the same tune, or they may represent another musical composition.

It will be noticed that the distance between the marginal holes a and b in the sheet is just one-half the distance between any two holes a a or b b, and as the movable musicpins in the cylinder are in line with the fixed feed-pins, and as the music-holes in the sheet are also in line with the marginal feed-holes a or b,it will result that only the piece of music represented on the sheet which will be played is the piece whose holes are in line with the marginal feed-holes then on the fixed feed-pins b in the cylinder. By this arrangement two important results are obtained. The space between the marginal feed-holes across the sheet is utilized to duplicate the music or for a different composition, and the necessity of unwinding the perforated sheet in order to play from the beginning of a piece is avoided.

As each composition commences at the ends, there will always be a piece ready to play from either end of the sheet without rewinding.

Should it become necessary to rewind, a rewinding mechanism is provided in the gear A and the pinion A. By moving the gear A out of mesh with the pinion A and into mesh with the pinion A rewinding may be done.

Should it be deemed desirable to stop the instrument before the end of the sheet is reached, the lever (Z is moved downward, bringing the spur (Z and the stop-pin d in the wheel B in engagement, thereby stopping the instrument, the slot d in the cross-piece (Z (l permitting this movement of the lever d.

As music is written to be played quickly or slowly, in an automatic instrument intended to play all kinds. of music it is important to automatically regulate the speed of the instrument so as to play the musical composition in about the same time in which it is written, without requiring any skill to regulate the time on the part of the user of the instrument. To this end I have provided devices shown in Fig. l, in which a cam-wheel O causes a lever C C to which a very light spring 0 is fixed, to move against a wheel B with varying degrees of force, thereby retarding the speed of the instrument to the requisite degree.

In the music-sheet, Fig. 12, a special set of holes 0 c c c is provided that permits the passage of movable pins 1), which come in contact with a spur-wheel B, to which the cam-wheel O is fixed, causing the spur-wheel to move one or more teeth, and moving the cam-wheel against the lever C C and the spring C against the wheel B with such force as the varying degrees of eccentricity 2 3 4: shown on the cam O, 1 being the normal or greatest speed and 4 the slowest, by reason of its greater eccentricity pressing the spring 0 with greater force against the wheel The line of holes 0 c c c are placed, one, a, at the front end of the sheet. This hole a, permitting the passage of a pin which actuates the cam O, leaves the regulating-spring C out of contact with the wheel B permitting the highest requisite speed. When the sheet reaches its end in the course of playing, the three other holes 0 c 0 permit the passage of three pins acting successively on the spur-wheel B, and will bring the cam-wheel O to the position of normal or 1 again. If the piece to be played is to be played slower that is, when the music is written in slow timethen two holes 0 and c are placed at the front end of the sheet, causing the cam C to move the spring 0 against the wheel B regulating the speed to the point 2 the desired speed. Then there will be only two holes on the same line at the rear end of the sheet, which will permit the passage of two pins actuating the spur-wheel and bringing the spring-regulator C to 1 again, or the normal speed. If it is desired to move at the slowest speed, there will be three holes at the front end of the sheet, as shown, when the marginal holes I) are on the feed-pins b and only one at the rear end, which will permit the passage of a pin to bring the speed to highest or normal. If it is desired to provide more than three changes of speed, the cam can be divided into as many degrees of eccentricity as desired.

It will be noticed that there are two lines of space in the music-sheet which have a like number of holes. The line on which I) and b are located and the line on which 0 c c c are located and when the sheet is reversed paper sheet do not come on the same line with the teed-holes in both cases; bntthe movable pins in the cylinder are located to register with them.

In automatic musical instruments hereto tore constructed the speed-regulatin devices consisted of adjustable fans or ilaps which are moved in. or out from the center of rotation nntnually, so as to suit the speed olf the instrinnent to any given. time of the music; but in such instruments the power is generally from a coiled spring, which when wound up tullygives out more power than when nearly run. down. Therefore it is necessary to manually change the position ot the fans frequently in order to secure the speed required for quick or slow music.

in my improved. speed-regulator I combine with the tans or I laps a pair of balls or weights [ixed to ilexible tlat springs centrally oi. their length, which when the speed is increased move out from the center ol. motion, similarly to jointed bars, by centrifugal. force, being opposed. by the torce ot' the springs, and. the fans blades, being lived to the balls, are also carried out from the center with the balls, thus presentil'ig a greater leverage to the action. of the air and. thereby automatically con serving the energy of the spring-power by preventing acceleration of speed, while the springs cause the return of the fans as acceleration of speed is checked, retarding the speed.

Should there he too great a speed or a too sudden increase of speed, the centrifugal force of the balls tlying from the center of motion will move the wheel. 13* upward, coming in contact with the spring b, which will. be an additional check on the speed; but it still too great to be checked by the spring 1) and the increased leverage of the fans, then the pin I) in the wheel B will come in contact with the bracket I) and stop the instrument.

In automatic musical. instruments of the kind to which my i1n )rovements relate a dznnper to arrest the vibration. of the sounding devices before they come in contact with the picker is anecessity. lliy improved. damper consists of a disk of thin sheet metal, having wings or wojections 71. pressed out of its periphery at g, forming the dampm-springs 71 (Shown in Fig. 8.) The disk is slightly greater .in diameter than the spur-wheel, the springs 7L2 are placed behind and between the spurs on. the spur-wheels. The disk and spur-wheel are 'iixed together so that the rotating movement of the spur-wheel is imparted to the daniper-wheel. The action of this damper in performing its functionv is seen by reference to Fig. n]. 111/ are vibrating reeds. The damper and s nnf-wheel rotate on shaft ii in the direction of the arrow, .liig. 7. So soon. as a spur-wheel sets the reed in vibration, having an intermittent motion, it ceases to move, the reed continuing its vibrations until. the spur-wheel commences its motion a ain carr in with it the dam. )er-whecl D 7 i b D, the bent wing 71?, which forms a spring,

coming in contact with the vibrating read and pressing it sidewise, arrests its motion. before the spmr-wheel touches the reed to again set it in motion.

Since the cylinder A has a fixed diameter, and the take-up has a constantly-increasing diameter due to the winding of the sheet upon it, the sheet would tend to break it a com- )ensati1'1g device was not provided to imidity the varying surlace speed of the take-up roller, and make it the same as the speed of the cylinder A. The wheel A mounted on the cylinder-shali't rotates the pinion A uni iornil y. To cause the speed of the periphery of the take-up roller to correspond with the speed ot the cylinder the flange F is mounted loosely on the spindle A. Its surl'acc has a leather washer .l and it is kept pressed. against the 'llange A", by the spring ii with sufficient force to be rotated by frictional contact with the flange A"; the nuts K serving to adjust the pressure to the requisite degree. 'Whcn the speed of the periphery of the take-up roller becomes greater than the speed. of. the cylinder the flange i will slip enough to bring the speed of. the roller to equal. that of the cylinder. The roller is shown in Fig. .l i. 'In its center is a longitudinal slot. The end of the sheet is made stit'f by additional thickness of material and placedin. the slot in the usual manner. The roller is given a rotation. or two and the paper sheet is secured. There are short slots in the ends of the tube-roller, which fit onto a pin K in the cup K. The roller is hollow, as shown, and is placedv in the instrument by pulling the thumb-nut KY backward against the spring K and placing the ends of the roller on the cup K. The springs K are intendedv to give only sul'licient force to bring the flanges to the ends of the rollers without exerting any pressure against them, the iillllll'Ib-lllltS K coming in contact with the bearings, as shown in Fig. 10.

I have shown a specific way of carrying out my inventimi; but I do not limit myself thereto,as various modifications and changes may be made within the scope of my invention, such as using the time-changing mechanism. in the middle of a tune as well as at the beginning 0t. one, or the time-changing mechanism may be applied to automatic instruments other than instruments having a perforated sheet.

It is also evident that the tan-blades may be made adjustable-inward and outward and that they may be made of such thickness to be of suilicient weight as to utilize the centril'fu gal :l:orcc,thus perli'm'nring both iu notions of weights and fan-blades.
