MUSICAL BOX.

SPECIFICATION forming part of Letters Patent No. 661,005, dated October 30, 1900,

Application filed SeptemherZZ, 1899. serial No. 731,281. (No model.)

To ctZZ whom, it may concern.-

Be itkn own that we, GEORGE VARRELMAN, a resident of the city of New York, borough of Brooklyn, county of Kings, and CHARLES M. EELS, a resident of the city of New York, borough of Manhattan, county of New York, State of New York, citizens of the United States, have invented certain new and useful Improvements in Musical Boxes, of which the following is a specification.

This invention relates to improvements in music-boxes; and the object of our invention is to provide a new and improved music-box which is so constructed that the note-disks used for operating the music-producing mechanism are automatically brought into playing position and after having been played are automatically removed.

In the accompanying drawings, forming a part of this specification, and in which like letters of reference indicate like parts in all the views, Figure lis a plan view of our improved musical box, the cover being raised in position for playing. Fig. 2 is an enlarged vertical sectional view of parts of the same, showing the construction of the retainingbar and its locking mechanism. Figs. 3 and 4 are enlarged detail views of the trigger for releasing the note-disks. Fig. 5 is a vertical transverse sectional view of the improved musical box, showing its rear end opened. Fig. 6 is a detail view showing a modification of the mechanism for raising the swing-frame. Fig. 7 is an enlarged detail side View of the mechanism for shifting the motorwheel. Fig. 8 is a plan view of the same. Fig. 9 is a front elevation of a similar instrument having the music-combs arranged vertically.

The music-box mechanism is of the wellknown construction, with one or two combs A secured on a base-plate A and combined with star-wheels, which pick the teeth of the comb or combs and which star-wheels are operated by a rotating metal disk provided on its under side with teeth or provided with slots for operating the star-wheels. The entire mechanism is contained in a casing A from the inner surfaces of the side walls of which two studs B project and on which studs a- U-shaped frame B is pivoted in such a manner that said frame can swing from the normal horizontal position over the base-plate A" into a vertical position, as shown in dotted lines in Fig. 5. This frame B is provided at the end of one leg with an extension B to which a helical spring B is attached, which is also attached to the bottom of the casing A, so as to counterbalance the said swingframe B.

The swing-frame B is provided at or near its center with a cross-bar 0, having at or near its center an arm 0, inclined downward and toward the rear for guiding the disks downward and toward the rear.

he size of the swing-frame B is such that a note-disk D fits within the rounded part of said swing-frame, as shown in dotted lines in Fig. 1, and thisframe B is so mounted, constructed, and arranged that.- when a notedisk rests on the same and the frame and disk D are in horizontal position the central hole D of the note-disk will register with the central pin E of the music-box mechanism, around which pin said disk is to rotate while playing. The central pin E is provided with a support E and secured thereto and upon which support the disk D rests while rotating to operate the music-producing mechanism.

The swing-frame B is provided at its closed end with a cross-bar F, having an aperture F, through which a pin F can pass, which is attached to one end of a lever F pivoted friction-tight at F to a bracket F of said cross-bar and which lever F extends beyond the frame B, so that it can strike against a pin G, projecting from the inner surface of the front of the box or casing A and can also strike against a bracket G, projecting from the inner surface of the hinged cover A of the box when said cover is in vertical posi tion, said bracket G being so located, as appears from Fig. l, as to be in substantially the same vertical plane of the projecting end on the lever F An inclined pin H projects from the inner side of the cover A near the swinging edge of the same and about at the center between the sides. Vertically above said pin a bracket J projects from the under side of said cover, and to one side of said bracket, at the free end thereof, a trigger K is pivoted, which is pressed downward by a spring K acting on it. The trigger is provided at its free end with a rectangular, tapering, slightly-rounded, and pointed nose K and from the side of the trigger a downwardly-curved arm K extends to within a short distance from the inner edge of the nose li at the end of said nose. A lever L, having a nose L like the nose K 'of the trigger K and slightly in advance of the same, is pivoted at L to the bracket J in such a manner that the trigger K overlaps said lever L, and

the rear end of said lever L is pivoted at L to the trigger K.

A series of note-disks D are suspended from the inclined rod H, said rod passing through the driving-holes Z) in the rim part of the disks, which disks are held from sliding off the pin H by the above-described trigger, as shown in Figs. and 4:.

When the frame B is swung into vertical position, its outer edge part strikes the curved arm K of the trigger K and swings said trigger upward against the tension of the spring K, whereby the nose K of the trigger is moved upward and above the edge of the front disk D on the pin H and permits this disk to slide otif said pin and upon the frame B. At the same time the nose L of the lever L is moved downward by the upward movement of the trigger and passes in front of the second note-disk D on the rod H, as is shown in Fig. 4, thus preventing said second disk from sliding oiit the pin H. lVhen the frame B swings downward and the trigger is no longer held by the same in raised position, the spring K presses the trigger downward, whereby the lever L and its nose L are raised, and releases the second disk Don the pin H, permitting said disk to slide downward on the pin H; but at the same time that the nose L is moved upward the nose K ot' the trigger is moved downward and in front of this second note-disk D, which has taken the place of the one just removed and holds the same, as shown in Fig. 3, and so on. The retaining-bar M of the conventional construction and provided with rollers m in the usual manner is hinged to a plate M on the innersurtace of one side wall of the casing A and is pressed upward by a spring M acting on its hinged end. On the free end of the retaining-bar M a head M is secured, which is provided on its under side with a recess M for receiving the upper end of the central pin E and with a lateral recess M for receiving the hooked upper end ot a latch N, pivoted in a vertical slot in the central pin E at N. A helical spring 0 has one end attached to the lower end of the latch N and the other end to a pin 0" on the under side of the base-plate A, which spring tends to press the upper hooked end of the latch N int-o the lateral recess M in the head M so as to engage the apertured plate M secured to the under side of the head M The latch N is provided at its lower end with. an arm N which rests upon the arm 0 of a rock-shaft O, journaled beneath the baseplate A, and provided at the opposite end with an arm 0 extending in the direction opposite to that of the arm 0. A helical spring 0", attached to the arm 0 and to the under side of the base-plate A, pulls said arm upward.

The retaining-bar M is provided near its hinged end and on its under side with an t..- shaped arm P, which extends under an outwardly-extending plate P on the under side of the swing-frame B when both of the parts are in lowered position, as shown in Fig. 2.

The drivingwheel R for rotating the notedisk D by engaging holes Z) along the edges of the same is fixed on a shaft it, carrying a pinion R engaged by an intermediate cogwheel R which in turn is engaged with the cog-wheel R mounted to rotate on the stud R on the side plate A of the mechanism. The cog-wheel R has a central hub or neck R, provided with two opposite holes or recesses d and d, Fig. 7.

From the barrel S (shown in dotted lines) of a spring-motor of any well-known kind a cog-wheel S is driven, which wheel is centrally pivoted at S on the upper end of the central member S of an inverted-T-shaped lever V, pivoted at S" to the side plate A A cog-wheel T is mounted to turn on astud 'l", projecting from the side plate A and is provided with a hub or neck T having a hole T A link T is pivoted by the stud T to the side of the wheel '1, and its opposite end is pivoted to the end 01: an arm 3 of the swing-frame B. An arm Textends from the stud T to a point slightly beyond the periphery of the hub or neck T and from the free end of said arm T a pin '1 projects laterally under the arm 0 of the rock-shatt O.

A substantially U-shaped lever \V, having upwardly and outwardly inclined end arms XV and W is pivoted friction-tight to the side plate A at W, and its arms Wand W are connected by the helical springs W and XV with the opposite arms V and V respectively, of the lever V, which arms V and V are provided on the upper edges with the studs or teeth V and V, which can passinto the holes 01 and T of the hubs or necks R and T of the wheels lit and T, respectively. A straight: lever U is pivoted near its upper end and near the lower end of each inclined arm W and W of the lever \V to the side plate A and is located between the said arms W and \V and the side plate A. A curved arm U extends from the upper end of each lever U to the upper edge of the straight portion of the lever \V, but is not connected with said lever \V. A helical spring U is attached to the lower end of each pivoted lever 7 and to the side plate A and pulls the lower end of each of said levers U outward, so that the curved arms U U are pressed toward the upper edge of the lever \V. A pin U extends laterally from the lower end of each lever U through a recess U in the upper edge of the corresponding arm V or V of the lever V, and each recess has a shoulder or offset U in its outer side edge.

A pin h projects from the inner side of the wheel T to act on the bottom edge of the inclined arm W of the lever W, and a pin g projects from the inner side of the wheel R to act on the bottom edge of the inclined arm W of the lever W. The stopping and starting lever Y is pivoted at Y to the side plate A and a spring Y is attached to the said lever Y and to the side plate A and serves for pressing the tooth Y on the lower end of said lever Y upon the periphery of the hub or neck R of the wheel R A bracket I, slightly inclined, is attached to the inner surface of the rear wall of the box or casing A and this rear wall is provided with an opening I, which can be closed bya door t', hinged at t" to open downward and outward and when held in open position by the brace 11 to form an outer continuation of the bracket I and with the latter a support for the discharged note-disks D, as shown in dotted lines in Fig. 5. The door thas two stops t.

In place of the mechanism shown and described for swinging up the frame B the construction shown in Fig. 6 may be used, and the same consists of a cam e on the shaft of the wheel S, which cam acts on a lever e, fulcrumed at one end, as at 6 and havingits opposite end connected by a pivoted link 6 with the arm B of the swing-frame B.

In the construction shown in Fig. 9 the disks D at all times are held vertically, the combs A are mounted in a vertical plane, and the retaining-bar M is mounted to swing outward horizontally. The wheels S, R, and T are mounted in the manner previously described and as shown in Figs. 7 and 8, with the difference that in the construction shown in Fig. 9 the wheel T is fixed on a shaft m, extending entirely across the casing and carrying an eccentric m, which operates a rod m for tripping the trigger mechanism K described in substantially the same manner as the swing-frame B does it. The retainingbar M has the hook P, previously described; but in this construction an arm 7t of the shaft 0 passes over said hook. A shelf 7 is se cured on an inclined shaft 1", mounted at one end in a step-bearing r on a side wall of the casing A and on the other end in a bracket r on the otherside wall, and the latter end of the shaft 1" is connected by a universal joint 0* with a short horizontal shaft r having a crank r, which is engaged with the swinging end of a lever s, pivoted at its upper end 3 to the casing A and pressed by a spring .9 against a cam-disk s on the shaft 772, which cam-disk s has a shoulder or offset 5 in its rim. A guide-rod textends longitudinally over the bottom part of one comb-A and has its free end '6' bent outward, so as to guide the note-disks D to the combs, the disks being held between said guide-rod t and the combs.

The operation is as follows: Referring to the construction shown in Figs. 1 to 5 and Figs. 7 and S, a number of note-disks Dsay from ten to fifteen or more-are placed upon the inclined pin Hin such a manner that the note projections on the disks are to the front, the cover A being raised, as shown in Fig. 5. To start the instrument, the starting and stopping lever Y, Fig. 7, is moved to the right, so as to withdraw the tooth Y on its lower end from the hole d in the hub or neck R of the wheel R", which wheel at once begins to rotate in the direction of its arrow, Fig. 7. When the wheel R has rotated but a very short distance, the hole d in the hub or neck R arrives at the tooth V of the lever V, and under the action of the spring W which is in greater tension than the spring VV the tooth V is forced into the hole (1, whereby the right-hand arm V of the lever V is swung upward and the central member S of the lever V is moved to the left, and thereby the wheel S is disengaged from the locked wheel R and engaged with the wheel T, which it rotates in the direction of its arrow. Thereby the arm B of the swing-frame B is pulled downward by means of the link T and the swing-frame B swung into vertical position. As the frame B swings up it also carries up with it the retaining-bar M, which has been unlocked from the central pin E. It will be observed that as the wheelT begins to rotate in the direction of its arrow the pin T begins to move from ,under the arm 0 of the rock-shaft O, permitting the spring 0 to pull upward the arm 0 of the rock-shaft O, which acting on the outer end of the arm N of the latch N presses the arm upward, thereby disengaging the hooked upper end of the latch N from the plate M on the head M The spring 0 holds the parts in this position until the wheel T has almost completed its revo1utio1'1-that is, until the pin T lifts the arm O by which time the frame B has been swung down, a note-disk brought into playing position, and the retaining-bar M swung down, as will appear shortly. YVhen the swing-frame B arrives at the vertical position, as indicated in dotted lines in Fig. 5, a disk D slides off the pin H in the manner already described upon the frame B, and at the same time the pin F on the lever F is passed through the hole a in the said disk as the outer end of the lever F strikes against the bracket G, whereby the other end, carrying the pin F is moved toward the inner side of the raised cover A and the pin passed through the hole ct. The swing-frame B is then swung down, and the pin F holds the notedisk just removed from the pin H in place on said frame. As the swing-frame descends the plate P on the same engages the hook P on the retaining-bar M and swings the latter down, and as by this time the pin T has raised the arm 0 and lowered the arm 0 of the rockshaft 0, and thereby released the catch N, the latter locks the retaining-bar M in place. By this time the pin h on the wheel T has arrived at the bottom edge of the arm W of the lever V and raised the same, whereby the spring W has been broughtin great-er tension, and as the opposite arm W has been swung down the tension of the spring VWis reduced, and when the hole T in the hub or neck T arrives at the tooth V on the arm V of the lever V the said tooth snaps into the hole T under the action of the spring W and thus the arm S of the lever V is swung to the right and the wheel 8 disengaged from the wheel T and engaged with the wheel Rflwhich begins to rotate and operates, by means of the intermediate gearing, the driving-wheel R, which rotates the disk D on the frame B, and thus the music-producing devices are operated. The tooth V is withdrawn from the hole d in the hub or neck R of the wheel R at the same time the tooth V snaps into the hole T After a short time the pin g on the wheel R strikes the bottom edge of the arm. W of the lever W and raises this arm and brings the spring TV in tension, at the same time slackening the spring W and so on the wheels R and T are rotated alternately to rotate a disk and operate the swing-frame B until the lever Y is adjusted to cause its tooth Y to snap into the hole (1 of the hub or neck R at the end of a tune, whereby the entire mechanism is stopped. When either end of the lever N is swung up, it permits the spring U of the opposite lever U to pull the lower end of said lever outward and to bring the pin U of said lever upon the shoulder U of the corresponding notch N, thus locking the lever V in place for the time be ing. For example, when the tooth V snaps into the hole cl of the hub or neck R on the wheel R the arm V swings downward and the pin U 011 the left-hand lever U is drawn by the spring U of said left-hand lever U upon the shoulder U on the arm V of the lever V, whereby said lever is temporarily locked in place. The other lever U is held in place by the raised part of the lever N, which bears against the arm U of said other lever U. Then the left-hand arm W of the lever W is raised by the pin it on the wheel T, the pin U on the left-hand lever U is withdrawn from the shoulder U on the arm V of the leverV and the right-hand leverU is released, so that when the tooth V snaps into the hole T in the hub T the right-hand pin U is drawn by its spring U upon the shoulder U on the arm V of the lever V. Fig. 7 shows the parts in intermediate position-that is, not locked by either pin U as the pins only lock the lever V when the mechanism is in operation and not when at rest, as shown in Fig. 7. Attention is called to the fact that the lock thus formed prevents the lever V from interfering with the wheel T or R that is rotated at the time being, and prevents accidental rotation of the other wheel. When the swing frame B swings down, the outer end of the lever F strikes against the pin G and is moved upward,

downward, and the pin F is thus withdrawn from the hole a in the disk D on the swingframe B, leaving said disk free to rotate. Then the swing-frame B rises, the disk D on the same and which has just completed a rotation slides off the rear part of said swingframe and upon the bracket I and the door t' or upon a disk previously deposited on said bracket.

Referring now to the modified construction shown in Fig. 9, the operation is as follows: When the mechanism is started and the wheel T rotated in the manner described, the pin 10 on the wheel T releases the arm 0 of the shaft 0 and the head of the retaining-bar M is unlocked from the central pin E in the manner previously described, and at the same time the retainingbar M is thrown outward slightly, but sufficiently to release the disk D, that has just been rotated, and at the same time the tooth or projection s of the lever .9 drops off the offsets of the cam'disk s and thereby the shelf 1' is tilted toward the rear and the disk D slides edgewise off the same to the bottom of the casing, as shown by one disk D in Fig. 0, and then the shelf 2 is immediately brought back into its original position. By that time the rod ta has tripped the latch K and one disk D is released from the pin II and drops edgewise upon the shelf 0', down which it rolls, and while so rolling is guided by the rod t, the fixed end of which forms a stop to hold the disk in the proper position. By this time the pin to on the wheel T moves outward the arm 0 of the rock-shaft O, and the arm n and O of this rock-shaft are moved inward. The arm 'n by acting on the L-shaped arm P of the retaiir ing-bar M. presses said arm against the disk, which retaining-bar is then looked in place by the latch N in the manner previously described. The wheel R is then rotated in the manner previously described and the disk D rotated around the central pin E, and so on.
