1 Claim. (Cl. 55-81) This invention relates to a toy cultivator disk and more specifically provides a disk for attachment to a toy tractor or other simulated vehicle.

An object of this invention is to provide a toy cultivator disk made up of a plurality of detachable sections wherein a child may secure the toy disk behind a toy tractor and simulate cultivating the soil.

Another object of this invention is to provide a toy cultivator disk wherein the disk elements are mounted upon angularly adjustable axles.

A further object of this invention is to provide a toy cultivator disk having means thereon for adjusting the angular relationship of the disk elements.

A still further object of this invention is to provide a toy cultivator disk for attachment to toy tractors wherein a child may simulate the cultivation of the soil.

Yet another important object of this invention is to provide a toy cultivating disk which is simple and rugged in construction intriguing to a child, easy to attach to a toy tractor and constructed of readily obtainable materials, hereby assuring a reasonable sale price.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as morefully hereinafter described and claimed, reference being. had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a top plan view of the toy cultivator disk of this invention attached to a toy vehicle;

Figure 2 is a side elevational view of the construction of Figure 1;

Figure 3 is a detail side elevation showing the axle adjusting means for the forward section of the cultivator disk;

Figure 4 is a detailed side elevational view showing the angular adjustment of the rear section of the cultivator disk;

Figure 5 is a longitudinal, vertical section taken substantially along section line 5-5 of Figure 1 showing the details of the disk elements and their mounting axles; and

Figure 6 is a transverse sectional view on an enlarged scale, of the mechanism for holding the disk assembly in adjusted position.

Referring now to the drawings, it will be seen that the numeral 10 generally designates the toy disk cultivator of this invention secured to a toy tractor or other vehicle generally indicated by the numeral 12. The toy tractor 12 is provided with the usual ground engaging wheels 14, a rear axle 16, a transverse brace or frame member 18 and a rearwardly extending hitch member 20 on the brace member 18.

The toy cultivator disk includes a frame member generally indicated by the numeral 22 and the frame 22 includes an elongated member 24 having a pair of apertured ears 26 at its forward end portion straddling the 2,798,359v Patented July 9, 1957 apertured hitch member 20 and a removable pin 28 is positioned through the aligned apertures for retaining the elongated members 24 in attached relation to the hitch 20. The removable eye member 28 is retained on the elongated member 24by a suitable flexible chain 30. The other end of the elongated member 24 is provided with an enlarged tubular member 32 having a removable cap 34 screw threaded on each end, and it will be seen that the cap 34 is provided with an aperture 36. An axle 38 having an enlarged head 40 is secured to the tubular member 32 with the enlarged head'40 on the interior of the tubular member 32 and the axle 38 projecting to each side of the tubular member 32. A plurality of dish-shaped disks 42 are secured to the axle 38 in longitudinally spaced relation by the nuts 44 which are secured to the axle on each side of the disk elements 42 for orientating the disk elements along the longitudinal length of the axle. The forward tubular element 32 is provided with a rearwardly projecting member 46 having an aperture therein for a purpose described hereinafter. A sleeve 48 is rotatably received on the axle 38 between adjacent disk elements 42 and the sleeve 48 is provided with a projecting lug 50 which pivotally receives a link member 52. A second link member 54 is secured to the link member 52 and is pivotally secured to a slidable sleeve 56 mounted on the elongated rod-like member 24. It will be seen that the sleeve member 56 has oppositely projecting lugs 58 for receiving the respective links 54 which are positioned in opposition to each other and are connected to the respective links 52 which are in turn connected to the respective sleeves 48 wherein upon sliding movement of the sleeve 56, the angular relation of the axles 38 in relation to each other may be adjusted. 'Ihe axles 38 are smaller in diameter than the aperture 36 in the tubular member 32 wherein a certain amount of angular adjustment may be provided.

As shown in Figure 3, the elongated rod 24 has a pair of abutment members 60 in the form of rings therearound in longitudinal spaced relation and disposed on opposite sides of the sleeve 56. A coil spring 62 around the elongated rod 24 is positioned between one, of the stop members 60 and the end of the sleeve 56 for continuously urging the sleeve away from the toy tractor 12. The sleeve 56 is provided with an upstanding lug 64 in right angular relation to the lug 58 and a connecting link 66 is pivoted thereto at one end. An upstanding lug 68 is positioned on the elongated rod 24 forwardly of the forward stop ring 60, and a handle member 70 is pivotally secured to the upstanding lug 68 by a suitable pivot pin 72. The connecting link 66 is pivotally secured to the handle 70 by a pivot pin 74 which is in spaced relation to the pivot pin 72, wherein pivoting of the handle about its pivot pin 72 will cause the sleeve 68 to move longitudinally of the elongated rod 24. It will be seen that the sleeve 56 is moved against the spring 62 and compressing the spring 62 when the axles 38 are moved in angular relation to each other, as shown in phantom in Figure 1. An upstanding latch or catch 76 is provided on the elongated member 24 forwardly of the lug 68 wherein the handle will be engaged thereunder for retaining the handle in position and holding the spring 62 in a contracted position wherein the disk elements 42 and the axles 38 may be retained in their angular relationship.

The rearward disk frame indicated generally by the numeral 78 is substantially the same, with the exception of the elimination of the projecting lug on the tubular member 32. The lug 46 is apertured and receives the hitch means 26 and the pin 28 in the same manner as the elongated member 24. The elongated member 24 of the rear frame member is provided with a transverse upstanding lug 80 and a threaded connecting link 82 is connected to thetslidable sleeve 56 and a rotatable nut 84 having a handle 86 is rotatably threaded 'onto the threaded member 82 whereupon by rotation of the handle 86, the sleeve 56 will be moved longitudinally of the elongated rod 24, thereby adjusting the angular relationship of the axle members 38. The connecting member between the sleeve 48 and the lugs 58 on the slidable sleeve 56 comprises only a single link, as indicatedby the numeral 88. Obviously, any suitable links may be used, as long as the links miss the disk element 42;

From the foregoing construction, the operation of the device will be readily understood. The toy cultivator disk may be attached to the toy tractor 12 by the use of the connecting pin 28 in an obvious .mannen'and if desired, the rear section of the disk 78 may be attached to the projecting lug 46 by the use of the other connect-i ing pin 28 in an obvious manner. If it is desired to change the angular relationship of the disk element 42 and the axles 38, the forward section 22 may be changed by operating the handle 70 and sliding the sleeve 56 relative to the elongated member 24, and the rear section 78 may be adjusted by rotating the handle 86 and moving the threaded member 82 and the sleeve 56 along the elongated member 24. It will be'un'derstood that the various elements of this toy cultivator disk may be constructed of readily obtainable metals or other material wherein the sale price of the device will be retained at a minimum. The toy cultivator disk of this invention provides an intriguing toy and one which simulates the cultivation of the soil wherein a child may easily simulate the various conditions and learn valuable lessons while he is enjoying the toy. Obviously, the toy cultivator disk of this invention may be attached to other vehicles than the toy tractor as disclosed in the specific embodiment.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary; However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim. a
