" DUPLEX-MUSlC-BOX;

SPECIPICATION forming part of Letters Patent No .356,25 l, dated-Fanuary 18,1887.

Application filed January 8, 1886.

To all whom it 7700/1] concern:

Be it knownthat I, ALFRED JUNOD, of Ste. Croix, Canton of Vaud; in the Republic of Switzerland, have invented a new and Improved Duplex Music-Box, of which the fol lowing is a full, clear, and exact description. The object of my invention is to provide a new and improved musical box which is' so constructed that the same melody can. be played by two independent cylinders on two independent combs, or a melody can be played by one cylinder on one' comb and the accom paniment by the other and independent cyl inder on the other comb, or that eachcylinder can play a melody alone, the other cylinder and'comb being out of operation-that is, re-' moved from the box. The invention consists in a music-box 'pro-- vided with two independent cylinders and two independent combs or groups of combs, 0ne comb or group of combs being provided for each cylinder, all as will be fully described and set forth hereinafter, andthen pointed out in the claims. v

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference. indicate corresponding parts in all the figures.

Figure l is a plan view of my improved music-box, the cover being removed. Fig. 2 is a cross-sectional view of the same on the line mm, Fig. 1. Fig. 3 is a crosssectional view of the same on the line y y, Fig. 1. Fig. 4 is alongitudinal sectional view of a cylinder mounted on its shaft. Fig. 5 is a detail view of part of the shifting mechanism. e

The musical box is provided with the usual. base-plate, A, on which the works are secured, and saidv plate is provided with the two longitudinal slots 13 B, into which the lower parts of the two pin-cylinders O O are passed,

and at the edges of the said slots the combs D D, or groups of combs, are secured on the base-plate A, one comb or group being provided for each slot.

Each pin-cylinder G or O' is mounted to slide on and turn with a shaft, E, provided at one end with a handle-knob, F, and at'the other end with a collar or shoulder, G, between which and the endof the cylinder a spiral Serial No. 187,950. (No model.)

cylinder in the direction toward the knob F.

On the endof each shaft E, and beyond the collar G,.a disk, J, is mounted, and from the edge of the said disk the handle-pieceor wing J projects, and from theother side of each disk J a pin,- K, projects. J

The cylinder-bearings L,.of, which there is one ateach end ofeach slot'B B, are pro-' vided with the latches M, .which are pivoted on the bearings and serve to lock the cylinder-shafts E in the bearings, the said latches being swung over the endpartsmf .the said shafts in the bearings. The cylinders can thus be removed from their bearings and replaced by others when it is desirable to play other melodies. y

The interchangeable cylinders are well known and are not to be elaimed'in this application, and are only described .to fully illusbox.

with the cog-wheel N, which engages with and revolves the pinion O on the shaft 1?, carrying the cog -wheel R, which engages vith and drives the cog-wheel R, mounted .on the shaft P, which shafts P and P are journaled in bearings on the base-plate A, parallel with the same.

The driving-spring is contained in the drum -M, mounted in suitable bearings and provided The shaft P .is also provided with the cog- I wheel Q, which drives the flier S.

On the outer surfaces of the wheels R and R the flat disks T are formed, which are provided in their rims with the notches U for ,re-

.ceiving thepins K, projecting from the sides of the disks J, whereby the cylinders are revolved. The driving-springis wound by means of the leverV in the usual manner or by means of a key.

On one end of the base-plateAthe two'parallel levers a are pivoted, to swing toward and from each other, and at their inner ends are pressed from each other by the spring 12, interposed between thern, and between the outer ends of the said levers the wedge-shaped piece 9 is provided, which is formed on the lower end of. a vertically-sliding rod, h, provided at its upper end with the handle-k nob m. From. the outer edges of the said levers a the arms I00 7o trate the character of my mproved music f R andR engage.

der. plays a melody-and the other-cylinder plays the accompaniment. In case on'ly one cylinder is to play at the time the othercylinder is removed. It is not necessary that the pins of both cylinders act on the teeth of combs, as the pinso't' one cylinder can act on' the ends of levers which operate orplay bells, drums, tambourines, :or reed instruments, such as are usually employed inlarge music-boxes.

If desired, the cylinders can beso constructed that they cannot be removed from. the box.

When it is desired to adjust the cylinders in such a manner that they are shifted length- -Wise after each revolution, the sliding bark is pushed down, so as to 'permit the spring d to press the endsof the leversla from'each other, so that the arms p can act on'thecams on theeylinders in the usual manner hen the cylinders are to be so adjustedthat they are not shifted lengthwise after teach revolution, the bark is raised, and then the wedge shaped piece 9 presses the outer, ends of the levers a from each other, thus preventingthe inner ends from being pressed apart by the spring (1. In some cases it is desirable that the two cylinders shall play one continuous tune, which requiresa series of revolutions of each cylinder-that is, the cylinders must be shifted lengthwise while playing said tune.

1 If both cylinders were shifted at the same time, a break would occur in the time, and to avoid this the shifting devices of the cylindersare so arranged that one cylinder is shifted at the time that the other is still playing. For instance, one cylinder plays a melody and is accompanied by the other; but before the first cylinder has completed its revolution the second one is shifted and continues playing, and ashort time after the second has been shiftedthe first completesits revolution and continues playing, and so on, the teeth or pins on the combs being so set that the melodyis not interrupted during the time that one cylinder plays alone, and also so arranged that at the time when the two cylinders play together again the teeth of each cylinder will play its proper part of the melody. To play a melody requiring a vconsiderable time,a pin-' cylinder having an extraordinarily large diameter is required in ordinary music-boxes, and to avoid these cumbersome, bulky, and expensive cylinders I have provided the double cylinders with shifting devices for the purpose of shifting them at different times.-

The cylinders can have any suitable diameter,

, BEST LABLE one and can be made any suitable length, as circumstances may require, and the combs may be composed of a series of sections.

The mechanism is contained in a box in the usual manner.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- 1. A music-box provided with two independent pin-cy1inders side by side and two independent combs or groups of combs, substantially as herein shown and described.

2. The combination, with two pin-cylinders, of an independent shaft for each cylinder, one drivi'ng'spring for revolving both shafts, and of an independent comb for each cylinder, substantially as herein shown and described.

3 The combination, with two pin-cylinders, of a comb for. each, cylinder, two separate shafts'for driving the cylinder-shafts, a cog- ,wheel on each driving-shaft,the cog-wheels engaging with each other, and of a spring for revolving the driving-shafts, substantially as hereinlshown and, described."- 7

j. 4.' In a music-box, the combination, with two cylinders, 'of' a shaft in each cylinder, a

disk provided with a laterally-'prbjecting pin on one end ofeach of said shafts, and of wheels having notches for receiving the said pins, substantially as herein shown and described.

5. In a music-box, the combination, with two cylinders, of shafts E in the cylinders, the disks Jon the ends of said shafts, 'the pins K on the said disks J, the cog-wheels R R on the shafts P P, the disks T on the cog-wheels,
