2 Claims. (01. 46-39) This invention relates to toy vehicles and is more especially concerned with a toy mowing device. j

A primary object of the invention is the provision of a toy mowing device having a laterally extending cutter blade assembly including a reciprocator cutter blade adapted for automatic actuation by the propulsion of the device.

A further object of the invention is the provision of a toy mowing device of the character indicated wherein reciprocatory motion is imparted to the cutter blade through the instrumentality of cam means fixed to and rotatable with the wheel'shaft of the device.

Another object of the invention is the pro vision of a toy mowing device wherein the cutter blade assembly may be elevated to inoperative vertical position in realistic simulation of an actual mowing device.

An additional object of the invention is the provision of a toy mowing device of the character indicated which may be fabricated inexpensively from a minimum number of parts which may be readily molded from any suitable synthetic plastic material.

The foregoing objects as well as additional objects and advantages of the invention will be readily apparent in the course of the following detailed description taken in connection with the accompanying drawings which illustrate a preferred embodiment of the invention, and where- Fig. 1 is a top plan view of the toy mowing device;

Fig. 2 is a sectional view taken on line 22 of Fig. 1;

Fig. 3 is a bottom plan view;

Fig. 4 is a view, partly in section and partly in elevation, taken along line 44 of Fig. l; and

Fig. 5 is a sectional detail view taken along line 53 of Fig. 3;

Fig. 6 is a fragmental side view showing the cutter blade assembly locked in its inoperative position.

Referring now to the drawings in greater detail, the toy mowing device includes a frame It which is preferably molded as a unitary structure comprising an elevated seat .II, a footrest I2, a pair of shaft bearings I3, and a forwardly extending tongue portion I4, terminating in a coupling I la, by means of which the device may be drawn along a supporting surface.

A shaft I5 is rotatably mounted in bearings I3 of frame In and wheels I6 are fixed to the ends of said shaft. Fixed to shaft I5 intermediate its ends is a cam wheel I! defining a plurality of 2 fluted or sinusoidal cam surfaces I'Ia for imparting oscillating motion to a connecting lever I8 pivoted at I 9 to the underside of frame I0 and engaging cam wheel H by means of a pair of lugs 20. Lever I8 may be further supported by .IBb in order to impart reciprocatory motion to the sliding cutter blade of the device in a manner to be fully described hereinbelow.

The device is provided with a cutter blade assembly,- generally designated by reference numeral 2-3, which is preferably affixed to frame III in such a manner as to be swingable from an operative horizontal position to an inoperative vertical position. In the illustrated preferred embodiment the cutter blade assembly 23 comprises a fixed blade 24, having projections 25 in simulation of teeth, which supports the slidable; reciprocatory blade 25 havin tooth projections 21. Fixed blade 24 is preferably provided along its rear edge with an upstanding guide rail 28 and is formed adjacent its free end with a transverse U-shaped guide member 29 slidably' retaining the outer end of reciprocatory blade 26. A depending leg 30 is preferably formed integrally with blade 24 for supporting the cutter blade assembly 23 on the ground surface in the operative position of Figs. 1 and 2.

Fixed blade 24 is formed adjacent frame I0 with an inclined wall portion 3| terminating in a bearing portion 32 by means of which cutter blade assembly 23 may be swingably mounted on a longitudinal pivot shaft 33 preferably formed integrally with frame Hi. As clearly shown in Fig. 2, a securing member 34 may be fixed adhesively or in any other desired manner at the open end of bearing portion 32 to complete the mounting of cutter-blade assembly 23 on pivot shaft 33, thereby preventing separation of said assembly from the frame I0.

Inclined wall portion 3| is provided adjacent fixed blade. 24 with a transverse guide slot 35 slidably retaining the inner end of reciprocatory blade 25. Said reciprocatory blade '26 carries an arm 36 having a rearwardly extending pin 36a, engageable between the depending legs Iflb of bifurcated portion I80, of the cam-actuated oscillating lever 58 for imparting reciprocatory motion to said blade.

Thus, as the device is drawn along the ground, cam wheel I! rotates with wheel shaft II5 to oscillate connecting lever I8. The oscillation of said connecting lever is accompanied by the reciprocation of slidable blade 26 as a result of the operative connection between said connecting lever and said slidable blade in the horizontal operative position of the cutter blade assembly 23 illustrated in Figs. 1 and 2.

When it is desiredwto swingmcutterlblade .as-. sembly 23 to vertical inoperativeiposition, a han r; dle knob extension 31 fixed to guide member 29 may be employed. In order to limit the rotation. .10

of cutter blade assembly 23 about its pivot 33" a stop-projection 38 is formed on inclinedawall 1F," 3|, said stop-projectionbeing received, in the vertical position of the cutterblade assembly; between a pair of suitably disposed projecting l5 lugs 39 provided on frame i B. Bifurcated portion l8a of oscillating lever i3 is preferably provided with an arcuate guiding arm 46 against. :which pin 35a of slidable blade 26 abuts in order to locate said pin in proper alignment between. de-.. pending" legs 815" when theputter blade assembly 231's dropped from its inoperative vertical posi-"- tion to its operative horizontal "position;

The device is preferably provided with lock ing means of any suitable conventiona'l'construc- '25 tion for releasably engaging cutter blade assembly 23-inits inoperative vertical position. 1

As-slidable cutter blade 26 reciprocates its teeth: 21 Inove into and out of registration with the:

teeth of fixed blade 24 "thereby simulating. 30

thecutting action of an actual mowing'machine with startlingverisimilitude." The registering position" of slidable blade 26*and teeth 21' is indicated in full lines in Fig; 2 while the broken" line position illustratesthe limiting non-register ing position of said'slidable blade and teeth.

Since certain modifications may be made in thetoydevice of the invention without depart-'- ing' from the scope thereofyit is intended that all-matter'contained in the foregoing specifica- 4-) tion and shown in the accompanying drawing be interpreted=mere1y as illustrative and not in a limiting sense.

What is claimed is:

1. A toy mowing device comprising a vehicle frame having a longitudinal axis, a shaft rotatably mounted on said frame, supporting Wheels fixed to said shaft, a cutter blade assembly swingably mounted on said frame for rotation from an operativehorizontal position to an inoperative vertical position, cam mean'slfixed to and rotatable With said shaft, said'cutter blade assembly comprising a fixed toothed bar and a slidable toothed bar supported thereupon, an oscillating leveryameans pivotally securing said lever to said frame,.. coupling. means. coupling one end of said lever to said..cam..means, the other end of said lever beingsbifurcated and having a pair of depending leg portions, said slidable cutter bar having an' 'exten'sion 'releasably engageable between the.-.bifurcated leg portions of said oscillating lever, whereby to impart reciprocatory motion to -.said slidable cutter .bar in theoperative position- .of;said;cutter1.blade assembly upon propul-..
