4 Claims.

The subject of this invention is a new article of manufacture in so far as essentially it provides the novel and valuable combination of (a) a music works of the kind which when set into operation emits a tinkle-melody tune, such works commonly referred to as a Swiss type music box, (2)) a main support therefor and on which the music Works and the means for manually setting the same into operation are permanently carried, the salient characteristic of which support is that it is a component part of a piece of juvenile furniture or a component part of a seating piece of furniture, for example a rocking chair, and (c) an improved means for manually setting the music works into operation and which means is particularly adapted for easy use in setting the music box into operation when permanently carried as just stated.

7 A subsidiary feature of the invention is, therefore, the provision of a novel and valuable such operating means per se.

The scope of the invention, in its broader and first explained aspect, is not to be limited to any particular manner of permanently mounting the music box on any specific type of juvenile furniture, as the piece of such furniture used may be, for instance, a corner post or some other part of a play-pen or crib, the liftable tray or some other part of a high-chair, or a hood-adjacent framing member or some other part of the body of a perambulator. For example, such permanent mounting may be efiected by the aid of utilization of a cavity or recess provided in a member ordinarily componental of any piece of -furniture of any of the kinds above indicated, all of which herein will be referred to and included in the designation piece of juvenile furniture, or said permanent mounting may be carried out by suitably securing the music box in a can, box or container of any kind or shape and then suitably permanently attaching such container or the like to the selected member of the selected piece of juvenile furniture, as against an otherwise exposed plane surface of said memher. But always the placement of the device of the invention then to be inbuilt, as it were, on said member, will be such as to present a manually graspable actuator for the music-works-opcrating means Within convenient hand reach of the child.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a fragmentary perspective View, looking down on a position of a piece of juvenile furniture, and showing the new combination in one possible embodiment thereof, and one, for example, including one possible kind and shape of can, box or container.

Fig 2 is a bottom plan view of Fig. 1.

Fig. 3 is an enlarged partial longitudinal sectional View taken on the line 3-3 of Fig. 1.

Fig. i is a bottom plan View of the sound emitting device, per se.

5 is a top plan view of Fig. 4.

Fig. 6 is a side elevational View of Fig. 5.

Fig. 7 is a horizontal sectional View taken on the line L-l of Fig. 6.

8 is an enlarged partial vertical sectional View taken on the line 8-8 of Fig. 7.

Fig. 8a is an elevation of the ratchet mechanism.

Fig. 9 is fragmentary bottom plan view of the sound emitting device, per se, and constructed in accordance with a modification of the present invention.

Referring to the drawings more in detail, and first to Figs. 1 to 8, the furniture member I B may, for instance, be assumed to be the outer end portion of the arm of an iniants high-chair; or, if. this Fig. 1 be viewed as though rotated through 510", said member may be assumed to be, say, a corner post or other upstanding part of the framework of a play-pen, crib or the like.

The can, box or container illustrated as included in the embodiment of the new combina" tion herein sh wn, may be such a container as that which is as a whole marked H. This container, as already stated, may be conveniently and inexpensively drawn and/or drawn and spun from a thin sheet metal; and as shown the same has basal annular flange l2 and a main hollow body i i. As this container also is illustrated, it is circular in basal outline and has generally a substantially spherical formation at its said main hollow body. However, as will be understood, the can, box or container, if present, can be made to any outline and to any shape and of any suitable material and in any way. The flange l2 or equivalent is conveniently present, to permit permanent securement of the container, as screws i 5a, see Fig. 2, passed through screw holes I5, to the selected furniture member.

With the main body of the container circular in cross section, there is suitably secured there- 'in, as by screws or the like it, a disc or other Referring particularly to Figs. 7 and 8, the music work [8 further includes the usual reed comb 2|] and the usual pin carrying cylinder 21. A larger gear 22' and an alongside smaller gear 23 are integral with a shaft 24 integral with said cylinder. A long length of the shaft 24 is telescoped into the sleeve portion of a long fixed shaft or bearing rod 25 having an end secured to a post portion 26 of the base casting H! by; a screw 21. A casing- 28 is secured to the base I 9 as by screws 29 sent down through two apertured ears offset from the open bottom of said casing. The casing 28 has an inturned neck portion: 311. for journalling therein the shaft 24' and beyond said neck portion said shaft 24' hasabevel. pinion 3i suitably fixed thereon. Largely in the casing 28 is a vertical shaft 31, collared near its upper end as at 33, and this shaft has fixed thereon a bevel pinion 34 for meshing withthe pinion 3i which is disposed at one end of the shaft 24. The other: end of. the shaft- 2L4: carries a: ratchet member 2% which: engages the: ratchetgear 23.

The wind-up spring is, shown at 335, this having one end 35a, thereof hooked: into aperture in the sidewall of the casing 28, and.- its other end 351) booked in through an opening in and? extending transversely of the shaft 32.

An air-brake. is provided, to assist in slowing down. the rate of unwinding of the'spring 35 after the same has been. wound up and released for unwinding; this air brake being driven from the gear" 23:, by meshing of the latter with: a. gear: 36 fixed on the same axis. with a tiny pinion 3.1, which pinion. is fixed, on the same axis with a worm-gear 3B meshing with a tiny worm (not shown) fixed on a small vertical. shaft 39. This shaft carries a shaped. strip 4%] providing: at: its opposite end portions the two vanes of the airbrake. A stamping 4| is attached: as by the screws indicated in Fig; '7 to the cast base l9; which stamping includes a lazy-U formation 4,150 forproviding a journalling mounting for the shaft 39, and also various upset lugs or lips for providing journalling mountings for the shafts carrying respectivelythe elements 36 and 31-38.

The lowermost length 42' of the main vertical shaft 32 is square in cross-section, so as to be keyingly engaged with the already mentioned pulley, 43, beyond the disc or rigid member [1. Wound around and in the groove: of said pulley is an elongate flexible element, as; the already mentioned cord, 44, one end of which cord may connected to the pulley as indicated at: 45. In the side wall of the casing H is: an aperture attended by a metal, rubber or plastic grommet 4,6, and through. the opening thus provided the cord is extended. Fixed to an intermediate portion of the cord 45 there is a limit ball 41, this desirably secured to the cord at a point such that when the spring 35 is fully unwound the limit ball will be in engagement with. the grommet 46, as shown in Fig. 2. The ball 41 is limited against sliding movement on the cord 44 by knots 48 formed in the cord on opposite sides of the ball 41.,

The free end of the cord 44 is then, slidably projected through a passage 49, see Figs. 2 and 3, formed in the member and which leads to the; edge of the member. The free end of the cord 44 is then provided with a safety-pull 44a in the form of a ball, which is in contact with the edge of the member Hl atthe outer end of the passage- 49 when the limit ball. 41, isagainst the grommet 46-, as shownin Fig 2.

The operation of the device should by now be obvious. With the safety-pull 44a at the location just mentioned, the same may be manually felt for and grasped, and then, on pulling the same, the cord will be unwound from the pulley until the limit ball engages the member In at the inner end of the passage; thereby rotating the pulley 43 in the direction of the arrow 43a in Figs; l and '7; or in spring-wind-up direction, loading the spring 35. As such tension becomes relieved, this following release of the grasp on the safety-pull 4411, the cylinder 2| is rotated in theproper direction to play repeatedly the tune provided for by the placement of the pins on the a cylinder 2!, such rotation being very slow, due in part: to the drag action of the air-brake and in part to the, large. speed reduction ratio of the gear drive from the shaft 32 over the bevelled gears 34. and 3!, the shaft 24 the ratchet member 23', ratchet gear 23 to the cylinders shaft 24; the. pulley 43 now being rotated in the direction of the arrow- 43b in Figs. 4. and '7, so that, when the repeat-repertoire ofthe music works; is. ended the limit ball 41 is again against the grome met 46- and the, cord 44 is again wound. on, the pulley 43.

Referring to, the modification illustrated in Fig. 9, wherein the parts to which are. applied reference numerals with primes added correspond, respectively, to, the parts to which have been applied the same reference numerals without primes, thereis provided on the main vertical shaft32, in-lieuof thepulley 43, a sprocket wheel 50. This wheel is engaged by a chain 51 ofsuit able length, passed through both of the two grommets 46' and at each of its opposite. ends carrying; a handle 52, Idler rotary discs 53, 53 may also be provided to hold thev chain against accidental disconnection, from the sprocketteeth. The arrangement is desirably such. that when one of the handles 52 is in engagement with its grommet 45, the spring is operatively loaded, and when the other handle 52 is in engagement with its. grommet 46', the spring is nearly unwound; and the chain 5| is desirably: of such length that a manual. pull. on the appropriate one; of said handles (which handle desirably would be brightly colored or chequered-surface formeretactile ready identification) may-be con,- tinued until they spring has been given a large degree of tension, and so that, at the conclusion of this tensioning, the other handle reaches and is stopped by its grommet 46', thereby giving positive protection against anychance. that the spring may be injured or made inoperative by too tight winding.

While we have illustrated and described the preferred embodiments: of our invention, it is to be understood that we donot limit ourselves to the precise constructions herein disclosed and the rig-htis reserved toall changes and modifications coming within the scopeof the-invention as: defined in theappended claims.
