AUTOMATIC MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 374,616, dated December 13, 1887.

Application filed January 21,1886. Serial No. 150.320. (No mcdcLl To all whom it may concern:

Be it known that I, JOHN MCTAMMANY, 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 a full, 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.

v This invention relates to automatic musical. instruments adapted to be operated by a perforated music-sheet either in the form of a strip attached at its ends to rolls, a fiat strip unattached, or of an endless belt.

The said invention consists, partly, in the combination of thewinding-roll which carries a. gear-wheel with an endwise-movable shaft carrying a pinion to engage with said wheel, partly in a spring for drawing said pinion into said engagement, and partly in a pivoted bar for holding said pinion out ofengagement, said devices allowing the instrument to be used with or without the winding-roll at will and to be rewound conveniently.

It also consists in the peculiar construction and arrangement of the instrument-case and sent-s a vertical longitudinal section on the line 00 a: of Fig. 1, the music-sheet and the rack being in place; and Fig. 3 represents a perspec tive detail view of the crank on the endwisemovable driving-shaft, and the pivoted bar for holding the latter in position.

A designates the casing of the instrument, within which all parts thereof are inclosed except the crank-handles and the pivoted stopbar. To the ends of this casing, at a a,are

pivoted two covers, A A, which meet in the middlewhen turned down,completely closing the top of the instrument. These covers are provided with handles A", for convenience in raising and lowering.

B designates the reed-board having reedduotsb,(lthedrivingshafthaving cranks c, and D the bcllows,operated by said shaft and cranks through pitmen d, all arranged and work ing substantially as in my Patent No. 248,943. This driving-shaft is provided with the usual detachable crank-handle,E,exterior to the easing, and with a pinion, F, which meshes with a gear-wheel, G, on the winding-roll H. Said shaft is also movable endwise to allow the engagement and disengagement of said pinion with and from said gear-wheel at will,and is provided at its inner end with a spring,which tends to hold it in such engagement. To relieve said shaft from such engagement, it is drawn outward against the resistance of said spring and held in this latter position by turning a pivoted bar between the crauk-handle E and the side of the casing. Said bar (marked I, )is attached to the exterior of the latter and recessed to fit the driving-shaft. \rVhen turned back,it of course leaves said shaft free.

The rewinding roll is designated by H. Heretofore these rolls, whichare removable from the instrument and commonly shipped by mail, have usually been provided with a crank at one end and ajournal-pin at the other. These appendages are of course injurious to other postal matter and the packages in which they are inclosed. This objection has been partly overcome by me, as described in a previous patent, by separating the crank from the body of the roll and interposing a sectional shaft, one part of which is connected to the former device and the other part to the latter, these two parts having a detachable mortiseand-tenon connection which allows the roll to be removed while the rewinding-crank remains attached to the casing. In the present draw ings the crank-shaft is marked J ,and the mor tise-and-tenon connection J. These turn, as

in said former patent, in a bearing having a spring-pressed cover, K. To more fully obviate the objections to the rewinding-roll hereinbefore stated, I have in the present instance substituted a smooth cylindrical extension, L,

of the roll itself for the journal-pin ordinarily used.

M designates the music-sheet, which is attached to the winding-roll at one end and to the rewinding-roll at the other. The movement of said sheet in playing is caused by the rotation of the driving-shaft transmitted to the winding-roll through the pinion and gearwheel before mentioned. When the sheet is to be rewound, the driving-shaft is drawn out and held out, as before described, and the operation of rewinding them meets with no impediment from the gearing.

N designates the rack, which is used only when an endless music-belt is to be substituted for the music-sheet before described. It is pivoted to the casing and constructed as shown in my Patent No. 321,738, having the usual pressure-r0ll,n,and upper feed-roll,n. The drivingshaft is covered with india rubber, n,to serve as a lower feed-roll. The rack being turned down,so as to bring rolls a a into position for use,and the driving-shaft drawn out,as before described, to free the pinion from the gearwheel, the instrument is readily operated in the usual manner.

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

1. The combination,in an automatic musical instrument, with the bellows-exhausters and a winding-roll havingagear attached tothe end thereof, of an endwise-movable driving-shaft provided with cranks and having a pinion mounted thereon that meshes directly with said gear-wheel on the winding-roll, pitmen connectingsaid driving-shaft cranks with the bellows-eXh-austers,arewinding-roll,and means for operating said rewinding-roll to withdraw the music sheet when the drivingshaft has been shifted endwise so as to slip its pinion out ofmesh with the gearof the winding-roll, substantially as set forth.

2. In an automatic musical instrument, the combination, substantially as described, ofthe music-sheetspool or rewi nding-roll,a winding roll having a gearfixed on its end,an endwisemovable driving-shafthaving mounted thereon a pinion which slides into and out of mesh with said gear, and a spring connected with said driving-shaft and acting to press it longitudinally in a direction to engage and retain said pinion in mesh with the gear of the winding-roll, for the purposes set forth.

3. In an automatic musical instrument, the combination,with a rewinding-roll,a windingroll having a gear-wheel attached thereto for operating it, and an endwise-movable drivingshaft carrying a pinion which engages said winding-roll gear and which can be disengaged therefrom by an endwise movement of the driving-shaft, of a movable stop-bar adapted to be moved into position to engage a hub or collar on said driving-shaft for retaining said shaft with its pinion out of engagement with the winding-roll gear, substantially as set forth.

4. In combination with a rack carrying an upper feedroll and a winding and rewinding roll journaled independently of said rack, a driving'shaft provided with a pinion for engaging a gear-wheel on said winding-roll and also adapted to act as a lower feed-roll, said driving-shaft being endwise movable in order that it may be used with either an endless music-belt or a music-sheet attached to a winding and rewinding roll, as set forth.

5. In combination with a rack,wiuding-roll, and rewinding-roll, an endwise-movable driving-shaft provided with gearing for operating said winding-roll at will, a spring for holding it in gear therewith, and astop-bar for holding it out of gear against the action ofsaid spring.

6. The pivoted recessed stopbaain combination with the endwise-movabledriving-shaft on which it fits and the crank between which and the casing said bar is interposed, substantially as and for the purpose set forth.

In testimony whereof I atfix my signature in presence of two witnesses.

JOHN MOTAMMANY.
