DISK TRUCK.

Specification of Letters Patent.

Patented July 11, 1922.

Application filed November 14, 1921. Serial No. 515,065.

To all whom it may concern:

Be it known that EDWARD E. JOHANNES and RICHARD D. DUNKnRToN, citizens of the United States, residing at Devon, in the county of Bourbon and Stateof Kansas, have invented certain new and useful Improvements in Disk Trucks, of which the following is a specification.

This invention has relation to certain new and useful improvements in a disk truck and has for its primary object the provision of a device of this character which will be constructed in such a manner that a direct pull may be obtained from the draft member to the disk and at the same time permitting the device to travel over the surface without danger of withdrawing the disk from the ground or interfering with the work thereof when the wheels of the truck pass over uneven or unlevel portions of the surface.

The invention has for another object the provision of a disk truck which will be of extremely simple construction and operation as well as highly efficient in use and in which the stub-tongue from the disk supporting frame may be connected with an upstanding bolt pivoted on the axle and connected with the single tree or other draft mechanism so as to permit raising or lowering of either end of the axle without tilting the standard.

carried by the axle or the stub-tongue extended from the disk frame structure.

The invention has for another object the provision of novel supporting and connecting members mounted on the axle in such a manner and connected with the stub-tongue as well as the draft mechanism of the truck so that the axle may he tilted independently of the members mounted thereon, without interfering with the line of draft or pull upon the stub-tongue of the disk supporting structure.

The invention has for a still further object the provision of a disk truck of the character stated which will he of inexpensive construction and may be employed for various agricultural implements without material alteration in construction and which will at the same time increase the efliciency of the implement bv making it possible to draw the same OX'GI the surface without side tilting of the implement and interference with the operation thereof.

With the foregoing and other objects in view as will appear as the description pro ceeds, the invention consists in the novel construction, combination and arrangement of cooperating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application and in which 1- Figure 1 is a front elevation of the truck, parts in sections.

Figure 2 is a side elevation thereof.

Figure 3 is a top plan view of the truck on a reduced scale.

Figure 4 is a detail view of the axle, removed.

Figure 5 is a detail sectional view on the plane of line 5-5 of Fig. 2, looking in the direction indicated by the arrows.

Figure 6 is a detail cross sectional view on the'plane of line 66 of Fig. 5.

Figure .7 is a slightly enlarged detail section on the plane of line 77 of Fig. 3, looking in the direction indicated by the arrows.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 indicates the axle of the truck having the central crank portion 2, as shown clearly in Figs. 1, 2 and 4 and provided with the ground wheels 3 at the opposite ends of the axle, these wheels 3 having their top portions 4 mounted on the end portions of the axle 1 in the usual manner as shown in Fig. 1 of the drawings. The hub portions 4 of the wheels 3 are prevented from moving inwardly on the axle 1 by the collars 5: engaged around the axle 1, these collars being formed in the ends of the arouate plate G by turning back these ends, as will be clearly understood by referring to Fig. 2. These collars 5 are loosely engaged around the axle 1. A standard 7 has its lower flat end pivotally mounted in the truck 8, which latter is loosely secured around the central crank portion 2 of the shaft 1. as shown at 9. This standard 7 is adapted to receive thereon the casting 10 or other members extending forwardly from the end of the stub-tongue ll projecting from the disc carrying structure. not shown. Downward movement of the stub tongue 11 on the standard 7 is limited by a stop collar 12 adapted to be adjusted longitudinally on the standard 7 and secured in adjusted position by a suitable set screw 13 or the like. Engaged on the upper end of the standard 7, above the casting 10 of the stub tongue 11 is the rearwardly extended end 14 of the inclined draft clevis carrying bar 15. This bar 15 also serves to retain the standard 7 in upright position and connect the same with the arcuate plate 6, the lower downwardly directed end 16 of the bar 15 being extended downwardly and connected with the forward central portion of the arcuate plate 6 by the connecting members 17 carried by the plate 6 and secured to the lower opening in said bar 15. This will be readily understood by referring to Fig. 2 of the drawings and by this figure as well as Figs. 1 and 3, it will be readily seen that the plate 6 extends forwardly in a horizontal direction from the shaft 1. The bar 15 has a plurality of suitably spaced clevis pin receiving openings 19 to receive the clevis pin 20 upon which the draft clevis 21 is carried and thereby serving to connect the draft apparatus, not shown, with the bar 15.

It is believed that the complete construction and operation of this device may now be readily understood without further detailed description. The operation may be briefly stated as follows, however. As the draft apparatus is connected with the bar 15 near the lower end thereof, and the stub tongue 11 connected with the disk carrying structure or other part of the implement to be drawn over the surface, a direct pull or draft will be exerted upon the tongue 11 and the standard 7 retained in vertical position, regardless of the unevenness of the surface over which the ground wheels 3 are passing, as the tilting of either end of the axle 1 will not affect the position of the standard 7 or the bar 15 and the stub tongue 11. The tilting of the ends of the axle 1 will simply serve to rock the horizontal arcuate plate 6 beneath the inclined bar 15, without any influence upon the latter, owing to the construction and mounting of the parts of the truck as heretofore clearly set forth. It may also be stated at this time that the stub tongue 11 may be adjusted vertically upon the standard 7 and the draft clevis pin 20 secured in the proper opening 19 of the bar 15 so as to obtain the best results. The construction of the clevis 21 may be readily seen by referring to Figs. 1, 2, 3 and T of the drawings in which this memher is shown as being of substantially U shaped construction with the natural bifurcated portion thereof mounted on the clevis pin 20 on opposite sides of the bar 15. It is believed that further description of this device is unnecessary.

While the preferred embodiment of the invention has been shown and described, it will be understood that minor changes in the details of construction and arrangement of parts may he resorted to within the scope of what claimed without departing from the spirit of the invention.

hat we claim is A disk truck comprising an axle having a crank portion, a standard having universal connection with said crank portion of the shaft at the lower'end of said standard, an arcuate member connected at its end portions with said shaft on opposite sides of the crank portion of the latter, said arcuate member being extended forwardly, an inclined member having a rearwardly turned end mounted on the upper portion of said standard. said standard beii'ig adapted to support a draft element carried by an agricultural implement, means adjustable on said standard, said draft element being limited in its downward movement on said standard by the last mentioned means, a forward draft element adjustably mounted on said inclined member, means for pivotally connecting the lower end of said inclined member with said arcuate member and ground wheels carried by said axle,

I In testimony whereof we aflix our signatures.
