United States Patent 3,491,904 DRILL TRANSPORT Albert C. Field, Minot, N. Dak., assignor of forty-nine percent to Dale 0. Backen, Minot, N. Dak. Filed July 5, 1968, Ser. No. 742,858 Int. Cl. B66c 1/00; B62d 21/00 U.S. Cl. 21486 Claims ABSTRACT OF THE DISCLOSURE A pair of transversely spaced apart and generally parallel support arms including engaging means on one pair of corresponding ends adapted to engage and be secured to an article to be supported against downward movement relative to the article, the other pair of ends of the support arms being suitably interconnected and having support wheel assemblies suported therefrom for vertical adjustment relative thereto and the support arms including portions thereof disposed intermediate a support wheel means and the article engaging means adapted to have portions of the article being carried bear down thereupon and be supported against downward movement relative thereto.

The transport of the instant invention has been specifically designed to provide a means whereby seed drills may be more readily transported from one location to another. The transport attaches to the frame of a drill and is operative to raise the rear end of the drill off the ground and to support the weight of the rear portion of the drill on the rubber tires of the transport. In this manner, transporting a seed drill from one location to another can be accomplished in less time and the extra wear and tear which would be incurred by the seed drill if it were not raised ofi the ground is saved.

The drill transport includes two I-beams which are generally parallel and aproximately seven feet long with a downturned lip at their forward ends. The forward ends of the I-beam are slipped between the press wheels from the back of the drill and the downturned lips are placed over transverse frame portions of the drill disposed forward of the press wheels. Then, the support wheel assemblies carried by the rear ends of the beams are lowered so as to raise the rear ends of the beams relative to the ground and the intermediate portions of the beams disposed between their front and rear ends are raised up into engagement with so as to raise, upon further elevation of the rear ends of the I-beams, a pipe previously passed through the spoked press wheels of the transport thereby insuring that the press wheels of the transport will be lifted clear of the ground. The main object of this invention is to provide a drill transport which may be conveniently used to transport a seed drill from one location to another.

Another object of this invention is to provide a transport assembly for transporting seed drills and which includes basic components which may be readily modified so as to adapt the transport for supporting and transporting substantially all types of seed drills.

Still another object of this invention is to provide a seed drill transport which may be readily operatively engaged with an associated seed drill and utilized to lift the rear end of the seed drill from the ground while the seed drill is maintained stationary against horizontal movement.

Another improtant object of this invention is to provide a drill transport which may be readily attached to and utilized for lifting an associated drill transport by a single workman.

ice

A final object of this invention to be specifically enumerated herein is to provide a drill transport in accordance with the preceding objects which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully 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 1 is a top plan view of a conventional form of seed drill with the drill transport of the instant invention operatively associated therewith;

FIGURE 2 is a rear elevational view of the assemblage illustrated in FIGURE 1;

FIGURE 3 is an enlarged fragmentary vertical sectional view taken substantially upon the plane indicated by section line 33 of FIGURE 2 and with alternate positions of the drill transport and seed drill illustrated in phantom lines;

FIGURE 4 is a fragmentary perspective view of one end of the drill transport illustrating more clearly some of the structural details thereof;

FIGURE 5 is a fragmentary vertical sectional view similar to the left hand portion of FIGURE 3 but illustrating the support pipe for the press wheels of the seed drill supported from a riser mountable longitudinally of the corresponding support beam of the transport; and

FIGURE 6 is a fragmentary enlarged vertical sectional view taken substantially upon the plane indicated by the section line 6-6 of FIGURE 1.

Referring now more specifically to the drawings, the numeral 10 generally designates a seed drill which includes a frame generally referred to by reference numeral 12 from which forward ground engaging support wheels 14 and 16 are journalled. The frame 12 includes a transverse member 18 and a plurality of rear press wheels 19 journalled on a rear transverse shaft 20.

The transport of the instant invention is generally referred to by the reference numeral 22 and includes a pair of elongated and generally parallel I- beams 24 and 26 including upper and lower flange portions 28 and 30 interconnected by means of upstanding web portions 32.

Each of the I- beams 24 and 26 has a riser member 34 slidably mounted thereon including an upper support flange 36, a longitudinal and upstanding web 38 which depends downwardly from the support flange 36 and a longitudinally extending lower flange structure 40 secured to the lower marginal edge portion of the web 38 and which defines a longitudinally extending channel member in which the upper flange portion 28 of the corresponding I-beam is slidingly received. Accordingly, each of the riser members 34 is shiftable longitudinally of the corresponding I-beam and it may be seen from FIGURE 3 of the drawings that each of the I-beams has a cross-bar 42 welded to the upper flange portion 28 thereof to prevent the corresponding riser member 34 from sliding off the rear end of the beam and that the support flange 36 of each riser member 34 has a pair of longitudinally spaced and transversely extending cross-bars 44 welded thereto for a purpose to be hereinafter more fully set forth.

The rear end of each support beam includes a vertically disposed support member 46 which is generally T-shaped in cross-section and has the upper end of its flange 48 welded to the rear end of the corresponding beam. The cross flange 50 of each support member 46 extends transversely of the transport 22 and has a pair of horizontally aligned and transversely spaced apertured mounting lugs 52 and 54 secured therethrough. In addition, the lower end of each flange 48 is apertured as at 56.

The transport 22 includes right and left hand tubular axle sections 58 and 60 whose left and right ends, respectively, are telescopingly engaged and the remote ends of the axle sections 58 and 60 include tubular socket members 62 and 64 which have one set of corresponding base ends secured to the sections 58 and 60 in any convenient manner such as by welding and whose other set of corresponding free ends project generally radially outwardly of the sections 58 and 60. Further, each of the sections 58 and 60 includes primary and secondary lever arms 66 and 68 which extend generally radially outwardly from the sections 58 and 60 and are secured thereto in any convenient manner such as by welding. The free ends of the lever arms 66 are pivotally secured between each pair of corresponding mounting lugs 52 and 54 by means of a pivot fastener 70 secured through both corresponding mounting lugs 52 and 54 and the corresponding lever arm 66. In addition, the free ends of the secondary lever arms 68 are apertured as at 72 and are registrable with the apertures 56 formed in the flanges 48 when the lever arms 66 and 68 are positioned as illustrated in FIGURE 3 of the drawings. A removable fastener 74 is provided for each secondary lever arm 68 and may be utilized to secure the free end of each lever arm 68 to the lower end of the corresponding flange 48 in a manner which is believed obvious.

A long support pipe 76 is provided and may be threaded through the spoked press wheels 19 in the manner illustrated in FIGURES 1-3. The support pipe 76 is of a length to extend through all of the press wheels 19 and to bridge the distance between the I- beams 24 and 26 whose forward ends are tapered in vertical height and are hooked as at 78.

In operation, when it is desired to lift the rear ends of the seed drill from the ground, the forward ends of the beams 24 and 26 are advanced forwardly between the press wheels 19 and engaged over the transverse member 18 of the frame 12 with the hooked ends of the beams 24 and 26 limiting rearward displacement of the beams 24 and 26 relative to the transverse member 18. Then, the support pipe 76 is threaded through the press wheels 19 above the beams 24 and 26 and a short length of the pipe 80 may have one end removably engaged in one of the socket members 62 and 64. Thereafter, the pipe 80 may be pulled from the vertically disposed phantom line position in FIGURE 3 of the drawings rearwardly and downwardly to the horizontal phantom line position thereof in order to rotate the axle section 58 one-quarter turn. This will of course swing the support wheel 82 journalled from the axle section 58 downwardly relative to the rear end of the beam 24 and thereby cause the latter to be elevated relative to the ground 86 from which the wheel 82 is supported. This in turn will of course cause the press wheels 19 on the right side of the seed drill 10 to be elevated from the phantom line position illustrated in FIGURE 3 of the drawings to the solid line position of FIGURE 3. Then, the fastener 74 may be passed through the free end of the secondary lever arm 68 and the lower end of the flange 48 supported from the beam 24. Thereafter, the short lever arm or pipe 80 may be removed from the socket member 62 and engaged in the socket member 64 of the axle section 60 whereupon the latter may also be rotated one-quarter turn in a similar manner and secured in adjusted rotated position to elevate the lefthand side of the seed drill 10.

If the transport 22 is to be utilized to support the rear end of a seed drill 10 including press wheels which are larger in diameter than the press wheels 19, the riser members 34 may be shifted to the desired position and the support pipe 76 may be cradled between the crossbars 44 secured to the support flanges 36 of the riser 4 members 34 in the manner illustrated in FIGURE 5 of the drawings.

From the foregoing, it may be readily appreciated that the transport 22 may be handled by a minimum number of workmen and that it may be readily operatively connected to an associated seed drill and actuated so as to elevate the rear press wheels 19 of the seed drill relative to the ground.
