(Cl. 46-175) tuating device for said mechanism, and means oper- .atively connecting said device to the mechanism whereby operation of the said device effects actuation of the mechanism and operation of the sound emitting device.

The connecting means may take the form of a mechanical connection such as for example a. link mechanism, a cord and pulley arrangement, or a Bowden cable. It may also comprise pneumatic or electromagnetic means. The actuating device may be mounted upon any convenient part of the toy such as for examplethe handle of a push chair or the base of a dolls chair or cradle; or it may be connected thereto by flexible means such as for example a Bowden cable, electric cable or pneumatic tubing.

Conveniently the sound emitting device may comprise a weight loaded bellows of the type known as a crier in which rotation of the bellowsabout a horizontal axis transversely thereof causes an intermittentsound to be emitted which sound may bemade to simulate the human voice.

The invention may be incorporated into the construction of a toy such as for example a pushchair, perambulator, a cradle'or bed, or a .dolls chair; or it may comattached to such The invention will now be described with reference to thetaccompanying drawings showing various embodiments thereof.

Referring to Figures 1 and 2 ofthe drawings, a push chair according to the invention comprises a seat 1 and a foot rest 2 supported on a pairof side frames 3, formed of lengths of tubular metal, which are in turn supported upon Wheels 4 rotatably mounted thereon by spindles 5. A handle indicated generally at 6 of substantially inverted ,.U shape supports a hollow back rest 7 which is secured thereto as by Welding for example, the legs of the handle being secured in sleeves 8 secured to the side frames 3. The spindles 5 are screw threaded to receive nuts 9 whereby the spindles. serve to secure the footrest 2 and the sleeves 8 to the side frames. The sleeves are formed at their upper ends with projections itl adapted to engage in apertures 11 in the Walls of the tubular side frames thus positioning the handle with respect to the frames. V

A crier 12 (Figure 3) is mounted within the hollow back rest 7 and is actuated by a member 13 pivotally mounted upon the handle by means of a pin -14 and operatively connected to the crier in a manner to be hereinafter described whereby rocking of the member '13 about its pivot efiects actuation of the crier.

Referring now more specifically to Figures 3, and 4, the hollow back rest 7 comprises a cover '15 secured to a base 16 joined along its side edges as by welding for example to tubular members 17 forming the legs of the handle 6. Pivotally mounted upon the base "16 by means of a stud 18 is a member 19 having at its upper end an arcuate rack 20. The rack 20 engages a pinion 21 secured to a spindle 22 journalled at one end in a boss 23 formed in the base 16, and having secured thereto at its other end the crier 12,

Thus rocking of the member 19, about its pivot ,18

"rotates the pinion 21 and spindle 22 by means of the bar 25 is pivotally connected at its other end to one arm of a bell crank lever 28 pivoted as at 29 upon the base 19. The other arm of the bell crank lever extendsthrough an aperture 30 in'the cover 15 and'is adapted to receive one end of a rod 31 extending upwardly through the tubular member 17, the rod being bent as at 32 to pass through an aperture33in the bell crank lever.

The upper end 34 of the rod 31'is pivotally attached as at 34a to the member 13 adjacent the end thereof, said member being of hollow box like form adapted to cover and enclosethe upper ends of the tubular members 17 and being pivotally mounted by means of the pin 14 'upon a channel section stretcher 35 extending between 'of the member 19 which by reason of the rack 20 and pinion 21 causes rotation of the crier 12.

1 In an alternative construction shown in Figure 4a, the 'rod 31 and bell crank lever 28 are respectively replaced by a flexible cord or wire 36 and grooved pulleys 37 and 38'. 'The pulley 37 is mounted upona spindle 39 extending diametrically across the sleeve 8, the diameter of the pulley being such'as topermit the cord 36 to pass freely throu gh'the tubular member 17. The cord 36 is secured at its upper end to the handle member 13 (not shown) and after passing over the pulley 37 passes through an aperture 40 in the back rest cover 15, over the pulley 38 rotatably-mounted upon the base 16, and is secured to the: endofthe link 25. The cord or wire 36 is tightly tensioned and may if desired include tensioning means such as for example a helical spring It will be apparent that rocking of'the member 13 alternatively effects a pull on the cord 36 thereby causing oscillatory movement of :the link 25 which in this modified construction is spring loaded as at 25a.

Figure 5 is a sectional elevation of a back rest embodying a modification of the actuating mechanism of Figures 3 and'4.

Inthe construction shown in Figure 5 a crank member 41 .journa1led at its lower end in a boss 42 formed in the base 16 and adapted to be rocked about its lower end, is bentat its upper end as at 43 to engage in a slot 44 in an arm 45 pivoted at its lower end as at 46 to a supporting bracket 47 secured to the base 16. The arm 45 7 supports at its upper end the crier 12 secured thereto by means of a clamp 48 so that the longitudinal axis of the crier lies substantially at right angles to that of the arm. The length of the arm 45 and the slot 44, and the positionof the pivot 46 are made such that when the crank member is at one extreme angular position, the arm 45 occupies a substantially horizontal position, and movement of the crank member to its other extreme angular position rotates the arm 45 through 180 thereby inverting the crierand effecting operation thereof.

Rocking ofthe crank member 41 is effected by a trans verse bar 49 journalled intermediate its length upon the crank member and connected at its ends to the bell crank levers 28 which levers are actuated, as in the construction shown in Figures 3 and 4 by rods passing through the tubular'members 17. Alternatively the bar 49 may be actuated by a cord and pulley arrangement similar to that shown in Figure 4a.

Referring now to Figures 6 and 7, a unit adapted to be attached to a toy comprises a base 50 and a cover 51 secured thereto. A crier 52 is secured upon one end of a spindle 53 by means of a support 54, the other end of the spindle being journalled in a boss 55 formed in j the cover 51, the said spindle having mounted thereon a pinion 56. The pinion 56 is adapted to engage a rack 57 formed on a transversely extending member 58 slid- .ably supported in brackets 59 secured to the cover 51 whereby oscillatory movement of the member 58 causes loscillation of the spindle 53 about its axis and actuation of the crier 52. i The member 58 is spring loaded in one direction by a spring 60 secured to one end thereof and to the cover 51'and has connected at its other end the wire 61 of a Bowden cable 62 secured to the cover as at 63 and provided at its free end with a suitable operating device (not shown) such as for example the known type of hand grip. Thus repeated operation of the Bowden cableoperating device eifects movement of the member 58 first in one direction and then in the other thereby imparting oscillatory movement to'the spindle 5'3 and actuation of the cr1er. a

Spring clips 64 are secured to the base 50 and serve for detachably securing the unit to a toy. Other suitable attachment means such as for example suction pads may be employed, or the unit may be adapted to be secured ber 19 is actuated by pneumatic means.

arcane by screws or nuts and'bolts when it is intended as a permanent attachment to an existing toy.

In the further modified construction diagrammatically shown in Figure 8, operation of the crier actuating mechanism is effected by electro magnetic means. In this construction the pivoted member 19 of Figures 3 and 4 is rocked from side to side by means of a transverse member slidably supported in a bracket 66 and pivotally secured at one end to the member 19. The other end of the transverse member is formed with a stop 67. adapted to be engaged by one arm of a bell crank lever 68. The other arm of the bell crank lever is slotted as at 69 to receive one end of a plunger 70 of magnetic material and slidably supported at its other end in a solenoid 71.

By alternately energising the solenoid, the bell crank lever 68 is rocked about its pivot by the plunger 70 thereby imparting oscillatory motion to the transverse member 65 to cause rocking of the pivoted member 19 and actuation of the crier, the member 19 being spring loaded by a spring 72 against the pull exerted by energisation of the solenoid 71. l

The electric power for energising the solenoid 71 is supplied by a battery shown diagrammatically at 73 which battery may be conveniently accommodated in the toy as for instance beneath the seat of the push chair shown in Figures 1 and 2. A switch 74 is connected by means of wires 75 to the solenoid and to the battery and it will be appreciated that intermittent operation of the switch will cause the solenoid to be intermittently energised thus oscillating the transverse member 65 and thereby rocking the pivoted member 19 to effect actuation of the crier in the manner hereinbefore described with reference to 1 Figures 3 and 4.

Figure 9 shows a still further modified construction of the mechanism shown in Figures 3 and 4. In the modified construction shown in Figure 9 the pivoted mem- To this end a piston rod 76 of an'air operated piston 77 sliding in a cylinder 78 is connected to the member 19 by means of a link 79 having a pin 80 sliding in a slot in the member 19. The member is spring loaded in one direction by a spring 82 secured thereto and to a bracket 83 secured upon the base 16, movement of the member 19 in the other direction being effected by outward movement of the piston 77. The cylinder 78 is connected by means of a flexible tube 84, passing through an aperture in the back rest cover 15 and a slot 86 in the tubular member 17 and extending upwardly therethrough to connect with a bellows 87 interposed between one end of a pivoted handle member'88 and the upper end of the tubular members. The bellows 87 is spring loaded to the extended position, the handle member 88 being pivoted on a pair of upstanding lugs 89 formed upon a flat bracing member 90 uniting the upper ends of the tubular members 17. It will be apparent that rocking of the member 88 about its pivot will cause the bellows 87 to be alternately contracted and extended thereby alternately forcing air into the cylinder 78 and evacuating it therefrom to effect oscillatory movement of the piston 77. The member 19 is thereby rocked about its pivot by the piston rod 76 and link 79 to eifect actuation of the crier in the manner hereinbefore described.

Operation of the piston 77 may be eflfected by means other than the bellows 87. For example the tube 84 may be connected to a deflatable rubber globe adapted to be secured to any convenient part of the toy or con- The flexible tubing84 is connected to the said air chamber and it will be apparent that pressure upon the rubber tube portion of the handle member by the hand of the user of the toy will eflfect operation of the piston 77 and actuation of the crier.

Figures and 11 show a further embodiment of the invention in which a dolls chair is provided with means for actuating a sound emitting device or crier mounted thereon.

As will be seen from the figures, a dolls chair comprises a pair of side frames indicated generally at 91, of metal tube bent to the desired shape to provide leg portions 92 and horizontal seat supporting portions 93. The leg portions of each side member are connected by stretcher members 94 and the frames are connected in spaced parallel relation by a front stretcher 95'and a rear stretcher 96. A seat 97 is supported from the frame portions 93 by brackets 98 which embrace the said portions and are secured thereto as by rivets 99.

A hollow back rest 100 is supported upon a base 101 extending downwardly therefrom and secured along its side edges as by welding for example, to the rear leg portions 92 of the side frames 91. A crier is mounted within the back rest 100 upon the base 101 which base also supports the crier actuating mechanism shown in Figures 3 and 4, the said mechanism being operated in the case of the construction shown in Figures 10 and 11, by a.

bell crank lever 102 pivoted on the base 101, one arm of the said lever extending through an aperture 103 in the rear leg member. The said arm is connected by means of a downwardly extending rod 104 to a projection 105 formed at one end of a rockable member 106 which projection extends through a further aperture 107 in the rear leg member.

The rockable member 106 is pivoted upon the rear stretcher-V96 and is spring loaded in the anticlockwise direction as viewed in Figure 11 so that foot operation of the said member by intermittent pressure of the foot of the user of the toy upon the end of the member adjacent the projection 105 effects rocking of the bell crank lever 102 and actuation of the crier operating mechanism.

It will be appreciated that instead of the construction described with reference to Figures 10 and 11, any of the constructions shown in Figure 4a, 5, 6, 7, 8 or 9 may .be incorporated into the dolls chair and, in the case of the constructions shown in Figures 6, 7, 8 and 9, remote controlled operating means may be provided for operating the toy at a distance.

It will likewise be understood that the invention is not limited to the above described embodiments thereof and that it is applicable to toys other than those shown in the drawings such as for example a doll's cradle or bed; or in fact any toy adapted to removably support a doll or like toy figure.
