Application April 24, 1952, Serial No. 284,024

17 Claims. (Cl. 16-114) This invention relates to toys and more particularly to push toys of the type propelled by a stick.

An object of the invention is to provide a push toy affording a spectacular sight, accompanied by acertain degree of sound. Another object is to provide a push toy of rugged construction commensurate with cost.

In general my invention comprises a cage in which a plurality of balls are carried. the balls being free to carom and bounce about at random. Means actuated by the wheels is utilized to strike the balls and bounce them about in the cage.

A detailed description will now be givenin conjunction with the appended drawing, in which Figure l is a front view in elevation of one form of the invention;

Figure 2 is a side view in section through 22 of Figure 1;

Figure 3 is a side view in section of another form of the invention;

Figure 4 is a side view in section of a further form of the invention;

Figure 5 is a perspective of the actuating means used in the form shown in Figure 4;

Figure 6 is a side view in section of a still further form:

Figure 7 is a front view of an element of Figure 6;

Figure 8 is an elevation in section of an additional form of the invention; and

Figure 9 is a front view of a portion of Figure 8.

Referring to Figures 1 and 2, the invention comprises acage having sides 2 and dowel spacers 4, holding aplurality of balls 6- which may be wood, rubber or of the Ping-pong type.

Blocks 8' and" 10 are secured between sides 2'; the former receiving apush stick 1 2 and the latter securing and supporting a pair of leaf springs 14, which may be of wood and which can be fastened in slot'16 in any suitable manner, preferably radial with axle 18 The cage is mounted on an axle 18 supported on and rotated by wheels 20. A pair of square cams. 22 are carried on and keyed to the axle, revolving therewith: as indicated by the arrow.

The arrangement is such that the balls.- gravitate tothe bottom of the cage; when the device. is pushed the: cam corners flex and snap the free ends of the springs repeatedly; the springs striking the balls. The balls are thus propelled in a random and rapid fashion, bouncing off the dowels and effecting an unusual combination of sight and sound. Ordinarily the stick is tilted at about a 45 angle when being pushed, which assures the balls being engaged by the springs. The cams may be offset 45 rotationally with respect to each other to reduce the torsional axle stress, thus making the axle easier to rotate and hence reducing the size of the wheels required.

In Figure 3 a simplified combination is shown wherein a cage generally designated as 28 holds a plurality of balls which gravitate toward the bottom and ride directly on a cam 30. The cam is of transverse width sufficient to prevent the balls from escaping downwardly; or a series ICC of spaced cams, olfset rotationally 45 with respect to each other can be used. In revolving, the cam corners protrude sufficiently into the cage to engage the balls and thus act as an impeller. The spacing between the uppermost dowels 32 is such that a child can remove and replace the balls, or other objects, such as spherical bells, blocks, etc. thus affording additional play value. The spacing between the lowermost dowels may be such as to accommodate a single transverse row of balls or a double row as shown.

In Figure 4 is illustrated a simplified version wherein the axle 34 carries a plurality of looped wire springs 36, which may be a continuous bent wire as shown in Figure 5, keyed by staples 38 to axle 34 or crimped thereon. The springs are preferably radial with axle 34 and are repeatedly flexed and snapped, as the axle rot-ates, against the dowel 40' which in this instance is shown as the only dowel in the rotational path of the free ends of the springs. This gives a snapping action only when the toy is pushed forward. The spacing between dowel 40 and the next adjacent dowel 42 is such that the balls are permitted to protrude downwardly a sufiicient degree to be engaged by the snapping springs and thus propelled about in the cage.

If a series of cams are used angularly offset with respect to each other so as to effect a plurality of spaced support points 360- about the axle, the wheels may be eliminated and the toy rolled on the cam combination, which is in effect, like a spiked roller as shown in Figure 6. The cams should be keyed tothe axle 44 to maintain their angular relationship and to keep the toy balanced particularly if square, rectangular or triangular cams 46, as shown, are used. If, however, pentagonal cams or cams having more than five sides are used they may be permitted to rotate on the axle at random, although they will ordinarily roll in unison.

The relationships described above are very general and, of course, proper operability depends on cam dimensions and coefficients of friction as well as the sharpness of the edges of the cams as they engage a floor.

What has been said above with respect to elimination of the wheels in Figure 6, also'holds with respect to Fig ure 1, wherein the toy can roll on a plurality of cams which also trip the springs, or on a single elongated cam preferably of five or more sides. The more the sides, the greater the tendency to roll rather than to slide.

It will be apparent that the form of carns illustrated could be replaced with an axle having a plurality of dowel pegs radiating from it spaced longitudinally and circumferentially so as toprovide engagement with the balls, while at the same time supporting the axle as it rotates.

Figure 8-shows a further modification comprising a conventional type of revolving: cage 50 andthe usual bracket 52. In this instance an axle 54 fixed to the bracket passes through the cage and a series of leaf springs. 56,. which may be severalin number (two being illustrated) are suitably secured in slots in the axle, radially extending. The. free ends of the springs extend into the spacings between dowel bars 58. They are preferably spaced circumferentially so that as the cage revolves, the springs are tripped one at a time by the bars to minimize the effort required to push the toy. Suitable longitudinal spring spacing is provided to achieve frequent striking of the balls wherever they may be in the length of the cage. The balls are thrown against the springs by the rotation of the cage, and the springs serve to snap in directions opposite to that effected by the rolling cage.

I am aware that many variations of my invention are possible and accordingly do not seek to be limited to the forms illustrated except as set forth in the appended claims.
