Letters Patent No. 105,972, dated August 2, 1870.

IMPROVEMENT IN MUSIGAL BOXES.

The Schedule referred to in these Letters Patent and making part of the sameA I, AMDE PAILLARD, of St. Groix, Gant-on de- Vaud, Switzerland, have invented certain new and usctnl Improvementsln Musical Instruments, of which the following is a specification.

Nature and Objects of the Invention.

My invention relates to that class of instruments commonly known as music-boxes, in which the melodies arc produced by a cylinder or barrel rotated by means of a coil spring, and studded upon its circumferencel with pins, so arranged in relation toa metallic comb that the pins will strike against the graduated Description of the Drawing.

Figure is a front elevation of the frameof au instrument, removed from the box in which it is usually inclosed, showing theI arrangement of theparts comcomposing my invention.

Figure 2 is a plan or top view of the same.

Figure 3 is a vertical transverse section through the plane z y, tig. 1.

Figure 4 is a similar sect-ion, taken in a plane immediately. behind and parallel with the bevel-gear M.

Figure 5 is an en'd view taken from the right hand end of iig. l.

General Description.

The rectangular frame A supports the vvvarious operative parts of the instrument, and has secured to it at either end two journal-boxes, a. a, in which the shaft O has its bearings. l

The two disks, B B, secured upon this shaft, furnish the bearings for the journals of the cylinders or barrels D, which are arranged between the disks at equal distances apart.

Each cylinder has a disk, E, secured upon the cnil of one journal, provided with a wrist-pin, f, and so arranged that it will revolve with the slotted disk e, when it is in such position that the wrist-pin is held in the upper part of the curved slot, as illustrated in the sectional view, fig 3.

lhe disk c is operated by the toothed'wheel d, gs. 2 and 5, which is keyed to its shaft c, and which is driven by the train owheels and coil spring, that are generally employed in these instruments to give motion to the cylinder.

The cylinders that are not in position to be rotated hy the disk e are held at rest in proper position, and prevented from turning accidentally by the spring detents p screwed upon the disk B, each dctent having a tooth, r, which catches into a hole in the face-plate upon the end of .the cylinder.

Each detent is withdrawn and held back from the cylinder, at thc proper4 time, by the stop P, secured upon the frame, so that the cylinder thus released is free to rotate with the disk e, with which it is in cooperative relation; the end of cach spring p projects beyond the cylinder a sufficient distance to insure of its striking against and being hcld by the cam-surface of the stop.

The main shaft O, which supports the cylinders,is revolved by means of the vertical shaft K, supported in the frame L.

The pinion k upon this shaft gears with the bevelwheel M, secured upon the end of the main shaft, and is made of such proportion that it makes .three revolutions tonne of the bevel-wheel M.

A second pinion, n, upon -the shaft K, drives the gear m, upon which the dial-plate N is secured, and makes three revolutions, also, to one of the wheel nt, so that the revolutions of the two gears, M and N, driven by the vertical shaft, are identical.

l*I he surface of the dial N is markedl at regular intervals with numerals, commencing with number one, to designate the number of cylinders in the instrument, and an index, o` secured above the dial, upon a stud which'passes through the gear 1n, and serves as a pivot for' the saine, is so adjusted that it-designates upon the dial the number of the cylinder that is in operation. l

llhe cover of the case in which the instrument is inclosed is provided with a list descriptive of the melodies performed by the instrument, and showing also what particular airs are performed by each cylinder, so that, by referring to the dial, the number oil the cylinder in play, and the tunes performed by it, can be quickly ascertained; and, also, any desired airs of those performed by the instrument may be produced at pleasure by turning the handle O forward until the index o indicates'upon the dial-plate.. the number of that cylinderupon which the required airs are arranged.

A. spring, F, secured to the frame A, g. 2, is so al ranged that its end presses aga-inst the circumference of the disk B, and catches into the notches b, for the purpose of holding the main shaft C rmly in the proper position to prevent the cylinder in operation from moving accidentally. out of place, with reference to the disk e and comb X.

This spring is released from the disk by pressing the handle Q, upon the lever H, down sudiciently to permit; the end i of the weighted elbowdever I to drop under and hold up the arm G, secured to and projecting from the side of the spring F.

By turning the handle O forward, while the leverI is holding up the spring, the shaft O may he turned to bring the next cylinder in play; the disks B B' will 'then revolve, carrying the cylinders until the next notch b conies under the end of the spring F, when one of the pins, g, upon the inner face of the bevelwheel M, strikes against the lower end of the elbowlever I and raises it high enough to withdraw the end i from beneath the arm G, and allow the spring F to drop into the notch b.

The pins g, fig. l, upon the face -oi the bevel-wheel M, are arranged in acirele tangent to the end of the elbow-lever I, and are so adjusted that they will trip the lever and releasethc spring F at the proper time, the number of pins employed being equal to the unmber of cylinders in the instrument, and, consequently, to the number ci' tunes it is required to trip the lever I and release the spring F.

The spring lever S is provided with a tooth, t, and is so arranged upon the ii'ame with relation tothe disk v T, fast upon the main shaft C, that it holds and prevents the shaft froml turning except when the slotted disk e is in proper position for the pin f of the next cylinder to enter the slot. At this moment the end ot' the lever S is raised by the pin u upon the circumference ofthe disk e, and thedisk T is free to revolve, so that the shaft O can only be rotated when thn disk c is in the position shown in iig. 5.

As the wristfpin fcannot bereleased from the curved slot in the disk e until the latter has made one entire revolution, und the cylinder is in the same position in which it was at the time the wrist-pin f entered the slot, and the tooth r of the spring p was drawn back by the action of the stop P, it follows that, when the spring p is released from the stop, the hole it the faceplate upon the end of the cylinder will be in position to allow the tooth r to readily enter it. l

'lhe vertical shai't K is prevented from being turned in the wrong direction by the ratchet-wheel g and a spring pawl pivoted to the frame L.

The cylinders D are shifted laterally between their bearings, to eect the change of tunes, in the manner and by the means that are commonly employed in constructing these instruments.

Claims.

What I claim as myinvention isf- 1. A series ot' cylinders arranged upon a rotating shaft, in combination with the comb X, so that euch cylinder in turn may be brought into co-operation with the comb, thereby making the instrument capable of producing a variety of tunes or melodies, substantially as described and specified.

2. Operating the series of cylinders by means oi' .the wrist-pins f and slotted di'sk e, substantially as described and specified.

3. The coinbinatiomt'vith the cylinders, of the spring detente to lock the'cylinders in proper position for the wrist-pins f to enter the slotted disk e, as the cylin'ders are rotated upon the shaft C, substantially as described and specified.

4. The cam-stop P, for liberating the detentsp from the cylinders, substantially as describedand specified.

5. The combination and arrangement of the lever H, 'weighted lever l, arm G, and pins g, for operating the spring-catch F, substantiallv as described and speciiied.

(i. The mechanism for rotating the cylinders around the shaft O, consisting of' the vertical shaft K, pinion la, and bevel-wheel M, in combination with the gear.

-m and pinion n, for operating the dial-plate, inthe manner substantially as described and specified.

7. 'lhe indicating mechanism N o, constructed suhsftantially as and for the purpose described and speciied.

8. The combination, with with the disk 'l upon the main shaft G, ofthe spring lever and cam-pin u, arranged and operating in the manner' substantially as described and specified.
