This invention relates to a transportation attachment for offset discs, harrows, and other farm equipment.

An object of this invention is to obviate the 5 costly loading and unloading of equipment on a trailer or truck.

Another object of the invention is the con,- struction of an attachment of the class hereinafter specifically described which can not only l be used on the offset disc, but also on any piece of equipment which one wishes to move.

The attachment is particularly advantageous to city or private lot cleaning concerns as the mechanism can travel over streets, curbs and sidewalks without injury to same.

A still further object of the invention is the provision of manually operated units near the corners of a frame, whereby a mechanism can be quickly adjusted for operation on a lot or field,

20 or, when desired, the mechanism can be adjusted to place the same in an inoperative position, whereby wheels are placed in position for conveying the mechanism over surfaces, without injury to such surfaces.

With the foregoing and other objects in View, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more par- 30 ticularly pointed out in the appended claims.

In the drawings:

Figure 1 is a View in side elevation of a mechanism constructed in accordance with the present invention; while Figure 2 is a top plan view of the same.

Figure 3 is a View in side elevation, showing the wheels raised to an inoperative position, and the disc in an operative position.

Figure 4 is a view in end elevation, showing the 40 wheels engaging the ground, with the disc in an inoperative position.

Figure 5 is an enlarged View of one of the crank-axle units, partly shown in elevation and partly in section.

Figure 6 is a sectional view, taken on line 6 5, Figure 5, and looking in the direction of the arrows.

Figure 7 is a perspective view of one of the four crank-axle units.

Figure 8 is a View in elevation of one of the four crank-axles, provided with an integral handle, while Figure 9 is a sectional View taken on line 9 9, Figure 8, and looking in the direction of the arrows.

Figure 10 is a view in elevation of one of the four auxiliary hooks.

Figure 1l is a fragmentary view, partly in elevation and partly in section, of another embodiment of the crank-axle units, while Figure 12- is an enlarged sectional View, taken on line I2-I2, Figure 11, and looking in the direction of the arrows.

Referring to the drawings by numerals, I designates a frame which comprises the front section 2 and the rear section 3. Each section includes parallel longitudinally-extending beams 4 to which are secured parallel transverse beams 5. The sections of the frame are suitably connected together, as the connection is not a part of this invention, nor are the discs, since my transportation structure may be applied to frames of different farm equipment.

In the drawings I have preferably shown four sets of wheel-carrying crank-axle units of similar construction, all attached to a frame, preferably near the corners of the sectional frame. Therefore, as these crank-axle units are duplicates it will only be necesary to specifically describe one. The crank-axle unit, near each corner of the frame I, comprises a pair of parallel substantially U-shape inverted suspension brackets 6. Each suspension bracket 6 includes a horizontal body portion l integral with parallel depending legs 8; each leg terminates at its lower end in an outwardly-extending horizontal foot 9. The feet 9 of each bracket 6 are preferably secured by bolts I0 to the same longitudinally-extending beam 4.

A crank-axle is employed comprising a horizontal portion II integral at its outer end with an inclined vertical portion l2, and this portion I2 terminates at its outer end in a spindle portion I3; to the spindle portion I3 is fixedly secured a spindle I4 upon which wheel I5 is mounted. All of the wheels I5 are preferably provided with pneumatic tires. Integral with the central portion of the horizontal portion II is a handle I6. This handle I5 includes an inner portion I'I, a central portion I8 and an outer portion I9 (Figs.

7 to 9). The portions Il and I9 are preferably formed in parallel planes. The horizontal portion II of the crank-axle is placed under the horizontal bodies 'I of suspension brackets 6, and U-shaped bolts are placed around this portion of the axle, with the bolts extending through bodies 'I, and nuts 2I are on said bolts 20, whereby the axle is revolvably mounted upon brackets 6. Against the outer edge of each bracket 6 and mounted on portion II of the crank-axle are locking collars 22; these collars are xedly secured to portion Il by any suitable means, such as a set screw, not shown. These collars 22 keep the crank-axle in correct position upon brackets 6, preventing any lateral movement or play. When the wheels are in engagement with the surface over which the mechanism is to pass, the outer portion I9 of the handle of the axle unit will be under the primary lock hook 23 (Fig. 7). When the wheels are raised to the inoperative position, as clearly shown in Fig. 3, with the discs in engagement with the ground, then the handles are hooked under the comparatively long auxiliary lock hooks 24.

In Figures y11 and 12 I have shown a modification designed particularly for orchard work, so that the wheels and the portions of the axles which stick up can be removed with very little effort, thus giving a disc that can be used for close work. In this embodiment the vertical inclined portion I2a is made of two sections, and on the abutting ends of these sections I place an annular clamp or sleeve 25 which has parallel lips 2B. Fastening bolts 2l extend through these lips 26, with-nuts thereon, whereby the sleeve can be securely clamped upon the ends of the portion l2a. A spline or key 28 is in the abutting ends of the axle section as well as in sleeve 25, preventing rotation of said sleeve on the axle. By this means the wheels can be quickly removed from the apparatus, and likewise can be quickly replaced after removal.

In carrying out my invention it will, therefore, be seen that I have preferably shown a frame provided with parallel longitudinally-extending beams upon which the suspension brackets are specically mounted for supporting the crankaxles.

In operation when the crank-axle units are in the position shown in Figures 1 and 2, the wheels l5 will be in engagement with the surface, and the handles of the crank-axle units will be hooked under the primary locking hooks 23. When the operator desires to p-lace the mechanism in position for the harrows to operate, all he has to do is to slightly move each handle to one side, to disengage it from hook 2S, or as hook 23 is pivotally mounted on the frame at 23a the hook itself can be moved to easily release the handle, whereupon the operator can swing the handle in a half circle, so as to bring it in engagement with the auxiliary locking hook 2Q, as clearly shown in Figure 8. Then the discs will be in position to operate.

It is also to be understood that the novel crank-axle units may be attached in like manner to frames of other equipment than a disc harrow.

While I have described the preferred embodiments of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacttue oi the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
