STEPHEN D. NEEDHAM, OF RANTOUL, KANSAS.

TRANSPORT-TRUCK FOR DISK HARROWS.

To all whom it may concern:

Be it known that I, STEPHEN D. NEED- HAM, a citizen of the United States of America, residing at Rantoul, in the county of Franklin and State of Kansas, have in vented certain new and useful Improvements in Transport-Trucks for Disk Harrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The objects of the invention are: First, to provide a traveling relay for the elevation and transportation of movables in transit. Second, to provide a traveling support for such implements as disk harrows to and from the field, and third, to provide an auxiliary traveling support for any disabled conveyance.

The invention consists in the novel construction and combination of parts such as will be first fully described, and then specifically pointed out in the claims.

In the drawings: Figure '1 is a view in perspective of a disk harrow showing the novel transport in rear of the harrow, and in position for forward movement. Fig. 2 is a side view of the harrow and transport as seen in Fig. 1, showing their position before the elevation of the harrow in dotted lines. Fig. 3 is a plan view of the harrow and the transport as seen in Fig. 1.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

For the purpose of elevating the separate frames of the disk harrow as shown, I employ a longitudinal beam 32 of a suitable length. Portions 33 of the ends of beam 32 are bent at right angles, and extend downwardly a considerable distance forming fulcrum posts, and portions 34 of the lower ends of the fulcrum posts are bent at right angles and extended outwardly a short distance in opposite directions to form axle bearings, and upon said bearings are mounted the spoked wheels 35, which wheels are secured on the bearings by the split keys 36. Upon the longitudinal portion of beam 32, and extending the length thereof is a loosely arranged sleeve 37.

38 indicates the stretcher bars or arms of the stretcher of the transport which consist of angle bars, the inner ends of which Specification of Letters Patent. Application filed June 9, 1911.

Patented Mar. 5, 1912. Serial No. 632,279.

bars are mounted upon the upper surface of sleeve 37the vertical portions of the angle bars being cut away adjacent said sleevethe horizontal portion 39- bearin upon said sleeve. The portions 39 of the angle bars are secured adjustably to the sleeve by means of the U-shaped clamping bolts 40, the ends of which bolts are screw threaded at 41, and said ends extended past the sleeve 37, and through the plates 39, and upon said threaded ends of the bolts are secured the clamping nuts 42. From the horizontal port-ions 39 of the angle bars of the stretcher the said bars are bent at an angle and extended forwardly and downwardly a short distance to a point 43, and at said point the arms or bars are bent at a slight angle and extended forwardly, and inclined downwardly in a slight degree to a point or crotch 44. From said point or crotch 44, the remaining portions of the arms extend forwardly in an upwardly inclined plane terminating in an upwardly extended U shaped grasping portion 45, the vertical port-ion of the angle bars in the U shaped beam grasping portions of the bars being cut away at 45*, as seen in Fig. 1.

Extending around the lower portions of the fulcrum posts 33, are clasps 46, the free ends being secured by the clamping screws 46*. To the clamping screws 46*, between said free ends of the clasps are pivotally secured the inner ends of the brace rods 47, the forward ends of which rods extend forwardly approximately to a point in line transversely with the crotch 44 in the stretcher arms or bars 38 when said bars are operatively connected with the disk harrow. Upon said forward ends of rods 47 are hooks 48, the portions of the hooks extending upwardly from the rods being bent backwardly a slight distance as seen in Figs. 1 and 2, so as to resist a direct upward movement when engaged with the disk harrow without first imparting a forward pull on the fulcrum posts 33 of the transport to disengage them.

Upon the outer surface of the stretcher bar 38, on the right hand side of the transport a slight distance forward of the crotch 44 is secured an eye plate 47*.

50 indicates the elevating lever on the transport which is approximately of the same length as the longitudinal portion of the main beam 32a portion --51 of ously the requisite which lever is bent at right angles and inserted within a socket 52, secured to the rear surface of the fulcrum post 33, on the right hand side of the transport-said socket is secured to the fulcrum post by means of the U shaped bolt 53, having screw threaded end portions, which extend through the ends of the clamping plate 54, and upon said ends are the securing nuts 55. Upon the upper end portion of the fulcrum post 33 on the left hand side of the transport, is secured a spring catch plate 56, one end of which catch plate extends rearwardly a short distance, and is bent forwardly a slight distance upon the free end of the elevating lever 50, so as to retain said lever in a folded posit-ion parallel with the sleeve 37, on the longitudinal portion of beam 32. The forward portion of the catch plate 56 supports a clip 56*.

In operation the main beam 32 of the transport is moved forwardly and downwardly in position until the bent portions between the point 43, and the crotch, 44, rest upon the ground. The forward ends of the stretcher arms are then extended for-- wardly beneath the respective shafts 12 and 14 of the disk harrow until the crotches 44, in said arms, are directly beneath said shafts, in which position the U-shaped portions 45, of said arms are hooked over the upper surface of the main draw beam 24, of the disk harrow. The free end of the elevating lever 50, is released from the catch 56, and moved outwardly and rearwardly. Power being applied to said end of the lever, a leverage is obtained on the fulcrum post to move the wheels 35, of the transport-forwardly in the direction of the disk harrow, thereby elevating both shafts 12 and 14, carrying the disks 15 simultanedistance above the ground. The hooks 48, on the ends of the brace rods 47, are then hooked over the sleeves 16, on shafts 12, and 14, separating the disks from each other. The harrow may now be moved to and from the field, supported by the wheels of the transport.

In detaching the transport from the harrow, the hooks 48, are disengaged from the sleeve 16, and under controlling lever 50, the sections of the harrow are lowered until the disks 15, rest upon the ground. The grasping ends 45, of the stretcher arms are then released from the beam 24. The beam 32 is then elevated by lever 50, and the hook 48 on the rod 47 on the right hand side of the transport is engaged with the eye 47 on the adjacent stretcher bar, and the rod 47 on the left hand side of the transport is elevated in posit-ion, as seen in dotted line in Fig. 1, and is held in said posit-ion by the clip 56*.

The invention is applicable as relay for the transport of disabled vehicles whenever a tire or'axle may be grasped by the stretcher arms, or in many instances the transport may be utilized for the conveyance of movable commodities or bodies.

In the employment of the transport for disk harrows, its efiectiveness in the application of power to raise the disks will be at once apparent.

Such modifications of the invention may be employed as are within the scope of the appended claims.

Having fully described my invention, what I now claim as new and desire to secure by Letters Patent is.
