This invention relates to a device which a j child can draw or'push around.

The principal objects of the invention are to provide a simulation of an interestlng object, as an aeroplane, which can be lifted or moved from one position to another on the device itself; to provide means whereby upon movingit into a more noticeable position a propeller or the like will be set into motion;

. to provide means whereby when it is being operated a sound will be produced to imitate the hum of a motor to provide means operable from the handle for moving the body of the imitation aeroplane orthe like back into lowered position which also will rotate the propeller automatically; to provide means whereby it can be made to rest on the floor right side up and in positionfor immediate operation, and to provide a simple and convenient construction of the various parts which involves very little mechanism not easily injured in operation.

Other objects and advantages of the invention will appear hereinafter.

. This invention relates to that class of childrens toys which can be drawn around the floor or sidewalk and can be operated to 5 produce effects,-while in motion, pleasing to children. n v v v I i The device comprises a 'Inain frame lO preferably made of two pieces of strip metal spaced apart and secured together by acrosspiece 11 to constitute aframe of skeleton form. At one end the strips of metal are bent downwardly and brought somewhat close together to furnish arms 13 having bearings for. the shaft of a wheel 12 on which 00 the device can be wheeled around or if wheels are not used, the same device is supported by these arms l3 which will support runners.

At the other end of the frame are two opposite projections 14. extendingdownwardly '65 at an angle to constituterests for supporting it right side up on the floor when not. in use. The extreme ends of these projections are brought up under a collar 15, which is "fixed to the bottom of the handle 16 which may be a wooden rod. On the shaftof the wheel 12 is mounteda toothed wheel :17.

The handle is provided with an operating rod or flexible wire 20 adapted to bemanipulated by a trigger 21 pivoted on the handle; shown as pivoted on the top of it and passing through a slot extending throughthe handle. Thisrod extends through the handle or outside it to the extreme end of the frameIO where it" is largely concealed by this'framei This rod is pivotally. connected with a pivot frame 22 of U-sha-ped construction. I This pivot frame is .pivotally mounted on the frame 10 and is provided with astop 28 for engaging this frame and preventing the swinging of the frame 22 beyond a certain limit. It is also provided with a fixed operating bar 2% having a transverse end, the purpose of which will be described.

The pivot frame 22 is duplicated by a frame 99 alle'l motion is provided as will appear.

25 alsopivoted to the frame anda par- This pivot frame 25 is provided with asteel spring 26 which, under certain circumstances, comes down into contact with the wheel 17 but in the position shown in Fig. 1, it is drawn up into the body of the article between the two strips constituting the frame 10. The frame also has a projection 27 with a hole through it through which the wire passes so as to keep this wire from swinging around. There is also anotherflguide 28 for this w1're:20. This guide '28 is fixed on the cross bar 11 which is used to make the frame 10' rigid.

Theframes 22 and constitute means for holding the strips 10 in place.

r The two pivoted frames22 and 25ers piv otally connected with the body 30 of the toy aeroplane. The pivots at both ends of the frames 22 and 25 are arranged in a parallelogram so that the motion secured is a parallel motion. The body 30, preferably of sheet .metal, is of a general' U-shaped construction from the body 3O near the end.

At the end of the aeroplane inside the thereof is a block of wood, metal or the on which is fixed a propeller 37 at one end and a toothed wheel 38 at the other end.

In the operation of the device the child wheels or draws the device around the floor or sidewalk by the use of the handle, of course. As it moves along he can operate the trigger 21 to pull the wire 20 and elevate the body I of the aeroplane by the parallel motion de scribed. In the process of elevating it, the projection 24: engages the toothed wheel 38 duringthefirst part of the ascent of the aero- "pla ne' body and gives it ,a turn. which Wlll spin the propeller. The same action occurs when the body is moved back. The body is heavy enough so that it does not remain elevated except as the trigger 21 is "held.

When this is released thebody will move back to the position shown in Fig. 1 spinning the propeller. Of course, during the motionof the device along the floor the spring 26 will engage the wheel 17 if the aeroplane body is elevated and make a noise imitative of the 7 noise of an engine but when the body is in its retracted position, as shownin Fig. 1, this springg26 is elevated and although the toy can bewheeled around the floor, the noise will not then be present and the propeller will not spin. 7 V i This toy'is very attractive to'children, par-' ticularly boys and introduces several features imitating'the action of an aeroplane. "It is prising a 'wh'eelsupporting itiat one 'end, a

As an article'of manufacture, a toy comframe carried by the wheel, :a handle at the other end of the frame for use in manipulate ing .the toy, a body representing an aeroplane, two parallel pivoted levers between the frame and aeroplane, and hand-operated means carried by the handle for raising said aeroplane. 1 7 v 2. In a mechanical toy, the combination of a frame adaptedto be moved from place to place, a wheel for supporting it, a pair of -pivots on the frame, a pair of links mounted on said pivots, a body above the frame, means for pivoting the two links to said body at points just as far apart as said pivots to constitute a parallel motiommeans on the handle for manually swinging one of said links about its pivot whereby said body can be elevated, a freely rotatable member on said body above the wheel, and means'car-ried by one of said links for turning said freely roe a t-atable member as the body is raised.
