18 Claims. (Cl. 298-8) This invention relates to a bulk hauler.

An object of the invention is the provision of a bulk hauler, which is provided with unique individual dumping buckets used for the transportation of bulk fertilizers, lime, feed, and sand or other such bulk material.

Another object of the invention is the provision of means for allowing the operator to select the bucket to be dumped at will, merely by inserting a locking pin in the power shaft, as well as the bucket collar, thus temporarily locking the selected bucket to the shaft.

A further object of the invention is the provision of a mechanism that has a single permanentlyLpositoned hydraulic piston, the thrust of which is transmitted by means of a fulcrum arm to a power shaft which extends the length of the body of the mechanism.

A still further object of this invention is the provision of a power shaft and locking pins, whereby the mechanism aords a bulk transport that is speedy in operation and is of unusual versatility.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of vparts as will be hereinafter fully described, illustrated in the accompanying drawings, .and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in side elevation of an apparatus constructed in accordance with the present invention.

Figure 2 is an enlarged vertical sectional view taken on line 2 2, Figure 1, and looking in the direction of the arrows.

'Figure 3 is an enlarged sectional view taken on line 3 3, Figure l, looking in the direction of the arrows, and showing the bucket in a dumping position.

Figure 4 is a fragmentary enlarged top sectional view of the apparatus.

Figure 5 is an enlarged fragmentary view, partly shown in section, of the apparatus taken along line 5 5, Figure 4.

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

Figure 7 is an enlarged fragmentary top sectional view of a portion of the apparatus.

Figure 8 is an enlarged sectional view taken on line 8 8, Figure 2, and looking in the direction of the arrows.

Figure 9 is a fragmentary plan view of the chassis, showing the power pack units attached to the frame.

Figure l0 is a fragmentary view taken on line 10-10, Figure 2, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the frame of the apparatus upon which is preferably mounted four buckets 2 (Fig. l) that are provided to contain the material, irrespective of its nature, that is to be conveyed or hauled to the desired place of deposit.

Extending along, and to one side of the top portion L Patented Mar. 22, 1960 of each bucket 2 is a single hollow shaft 3 that is journalled in collars 4. These collars 4 are xedly supported upon the upper end of standards 5 (Fig. 1). Each standard 5 is fastened at its lower end preferably to the side of frame 1, additional angularly disposed standards 5A extend from each collar 4 to the opposite side of frame 1, as shown in Figure 1. In Figure 6 is shown the position of attachment of the collars 4 at the upper ends of the standards 5, and the relation of the shaft 3 to the buckets 2.

For each bucket 2 there are two collars 6 located on the single hollow shaft 3. Securing and reinforcing plates are secured to and extend between collars 6 and buckets 2. Two locking shafts 7 are provided for each bucket 2. The upper end of each shaft 7 is pro vided with a locking bolt-like pin 8 (Fig. 2) which is adapted to extend through registering apertures 6a and 3a in collars 6 and shaft 3, respectively (see Fig. 5). A fragmentary view of the bucket collar 6 is shown in Figure 5, as well as the locking pin 8 inserted through the bucket collar 6 and the shaft 3. When the bucketpin is thus inserted through the registering apertures 6a and 3a in the collars 6 and the shaft 3,'this particular bucket is locked to the shaft and ready to be dumped. The locking pins 8 inserted through the collars 6 are shown in Figure 7. The lower end of each locking shaft 7 is bent at right angles at 9, as shown in Figure l0. These ends 9 are placed in notched brackets 10, whereby the particular blucket 2 is locked against independent movement upon the rotatable hollow shaft 3. Each bucket unit is provided with this locking system, whereby any particular bucket can be operated for dumping, as the operator desires. When the locking means of each bucket is not in use, then the rotary shaft 2 may be turning idle until the operator locks one or more of the buckets to shaft 3.

To rotate the shaft 3 a hydraulic cylinder 11 is provided from which a piston 12 extends. The cylinder 11 is suitably pivotally supported at 13 (Fig. 3) upon the frame 1. The piston 12 is connected at its outer end 14 to the arm 15, which arm is welded or otherwise permanently secured to the hollow shaft 3. A hollow hydraulic supply pipe 16 supplies the cylinder 11 with the power when the cylinder 11 is operated at the central control 18 (Fig. 3) for swinging arm 15 and thereby dumping the contents of bucket 2. The enlarged top sectional View of this portion of the apparatus (Fig. 4) shows the cylinder 11 to be centrally located between the buckets 2. The central control 18 (Fig. 9) is in turn connected with the power pack units 19, such units to be affixed to the frame 1.

When the bucket 2 is dumped (Fig. 3) the hinged cover section 17 of fixed cover 17A, which is hinged at be dumped, the outwardly swinging section 17 of the top acting as a guide for the passing of the material out of the bucket. Handle members 17B are provided on section 17A to facilitate manual dumping of the buckets when necessary or desirable.

When the power is removed from the cylinder 11, the bucket 2 will swing backwardly intolposition as shown in Figures l and 2. A section along lines 8 8 (Fig. 2) shows that when the buckets 2 are at rest, their bottoms 2', being of curved section (Fig. 8) extend below the top ofthe frame 1, thus lending rigidity and strength to the whole unit.
