JOHN HAGEDORN, OF SALEM, MISSOURI.

SPRING-CULTIVATOR.

Specification of Letters Patent.

Patented Dec. s, 1908.

Application filed September t, 1907. Serial No. 391,371.

To all whom it may concern:

Be it known that i, Jenn l-laenoonn, a citizen of the United States, residing at Salem, in the county of Dent and State of Missouri, have invented a new and useful Spring-Cultivator, of which the following is a specification.

The invention relates to improvements in cultivators.

The object of the present invention is to improve the construction of cultivators, and to provide a simple and comparatively inexpensive one of great strength and durability, designed particularly for use on rocky and stumpy ground, and having resilient cultivating devices, which will not be broken should they come in contact with a rock or stump.

A further object of the invention is to provide a cultivator of this character, capable of lateral movement and adapted to be easily shifted from one side to the other for dodging corn, or a stump, and also for moving it upward when cultivating a hillside,-whereby the cultivator is prevented from slipping down the same.

It is also the object of the invention to provide a cultivator, which, should any of its parts become broken, may be readily repaired by an ordinary blacksmith, so as to avoid the inconvenience and expense of shipping the cultivator, or any portion thereof back to the factory for repair.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the.

scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation of a cultivator, constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a plan view of the cultivator. Fig. 4 is a rear elevation of the same. Fig. 5 is a detail sectional view, illustrating the manner of mounting the spring cultivating devices. Fig. 6 is an enlarged detail perspective view of one side of the main frame, illustrating the construction and arrangement of the caster wheel for supporting the same. Fig. 7 is a side elevation of the cultivator, the trans verse supporting bar being interposed between the caster wheel frames and the main frame to interlock the same and to support the cultivating devices above the ground. Fig. 8 is a rear elevation, partly in section.

Like numerals of reference designate corresponding parts in all the figures of the draw mgs.

The main frame of the machine, which is preferably constructed of a combination of wood and metal, is provided with front and rear continuous top

transverse bars

1 and 2 and front and rear bottom

transverse bars

3 and 4, arranged in pairs and located at opposite sides of the center of the cultivator, and connected with the top transverse bars by means of front and

rear arches

5 and 6. The top transverse bars, which extend entirely across the cultivator, are connected at their terminals by longitudinal end bars 7, and the bottom transverse bars are also connected at their outer ends by longitudinal end bars 8. The transverse bars and the said end bars are preferably constructed of wood, such as well seasoned oak, or other suitable material, and the top transverse bars are connected by contrally arranged diagonal braces 9 and metallic longitudinal bars 10, located adjacent to the wooden end bars 7, as clearly illustrated in Fig. 3 of the drawings. The diagonally arranged braces, which are crossed beneath the rear portion of a centrally arranged draft beam or tongue 11, are secured at their terminalsto the lower faces of the top transverse bars, and they prevent the top of the main frame from sagging.

The front and rear arches, which are constructed of metal, have upwardly and inwardly inclined sides and side connecting top portions, which are secured to the lower faces of the top transverse bars by the

bolts

12 and 13, or other suitable fastening devices, which also secure the rear portion of the draft beam or tongue to the top transverse bars. The draft beam or tongue is recessed at its lower face to receive the top transverse bars, and it assists in bracing the top of the main frame. The arches are provided at the lower ends of their sides with outwardly extending transverse portions or arms 14 and 15, arranged at the upper faces of the bottom transverse bars and reinforcing the same, as clearly illustrated in Fig. 7 of the drawings. The top and bottom transverse bars are connected at the sides of the cultivator by means of front and rear vertical bars or

members

16 and 17, 1 and it permits the front end of the main lonhaving their upper and lower terminals bent at right angles and secured to the top and bottom transverse bars. The bottom transverse bars are connected adjacent to the end bar 8 by metallic braces 18, which correspond in arrangement to the upper metallic bars or braces 10. The metallic portions of the main frame are designed to be constructed of malleable metal, or other suitable material and they may be varied in size to provide a frame of the desired strength. Also they are adapted to be readily replaced by an ordinary blacksmith, should any of the parts become broken.

The cultivator is provided at each side with a plurality of spring cultivating devices, which are adapted to yield to prevent injury to them should they strike a stump or rock. In the accompanying drawings, the cultivator is equipped with two of these cultivating devices at each side of the main frame, but three or more may be employed, as will be readily understood. The inner cultivat ing devices 19 carry shovels 20, which are arranged in advance of the shovels 21 of the outer cultivating devices 22, but the cultivating devices may be reversed as they are detachable and adjustable, as hereinafter more fully explained. Each spring cultivating device consists of a main longitudinal spring 23 and a rear bracing spring 24, as 0 early illustrated in Fig. 6 of the drawings. The main longitudinal spring has its front portion 25 curved upwardly, and its rear portion 26 is curved downwardly, the intermediate connecting portion 27 being approximately straight. The front end of the longitudinal spring 23 is bent at an angle, and is secured to the lower face of the front bottom transverse bar 3 by a bolt 28, but the front end of the spring 23 is adapted to be arranged at either the upper or lower face of the bar 3 to adjust the rear end of the cultivating device. The rear spring 24 is pro vided with a substantially semi-circular front portion 29, extending upwardly from the main longitudinal spring at a point near the center thereof and secured at its upper end to the lower face of the rear transverse bottom bar 4 by a bolt 31. The rear spring is also provided with a straight intermediate portion 32 and a downwardly curved rear portion 33, which fits the straight rear portion 27 and the downwardly curved portion 26 of the main longitudinal spring 23 to re inforce the same and to provide a resilient cultivating device of great strength and durability. The resiliency of the cultivating device, however, may be increased by omitting the straight portion 32 and the downwardly curved rear portion 33 of the rear spring. The rear spring 24 forms a yieldable connection between the main longitudinal spring and the rear transverse bottom bar,

I gitudinal spring to be arranged on either the upper or lower face of the front transverse bottom bar 3. By transferring the front end of the main longitudinal spring 23 from the bottom to the top of the bar 3, the rear end ofthe cultivating device is thrown downward in the direction of the ground, and a reverse movement of the front end of the main longitudinal portion 23 operates to raise the rear end of the cultivating device. The cultivating devices may be equipped with any preferred form of soil-engaging device, and the blades or shovels may be arranged to throw the soil in either direction. The bottom transverse bars and the laterally extending arms or portions of the front and rear arches are provided at intervals with

perforations

34 and 35, to permit the cultivating devices to be adjusted toward and from each other, and to be arranged either in parallelism with the tongue or at an angle to the same. l/Vhen the cultivating devices are arranged in parallelism with the beam, as illustrated in Fig. 3 of the drawings, corn can be cultivated without ridging the ground, which will be left level. The blades or shovels are detachably secured to the rear ends of the cultivating devices, and are adapted to be readily removed to sharpen 5 them or for any other purpose.

The sets of cultivating devices are connected by transverse and

diagonal braces

36 and 37, secured to the cultivating devices at the intermediate straight portions of the springs by bolts, or other suitable fastening devices and provided with a plurality of perforations to permit the lateral adjustment of the cultivating devices. The diagonal braces 37 extend rearwardly and laterally from the inner ends of the transverse braces 36 to the outer cultivating devices, and their rear ends are secured to the same at the rear terminals of the straight portions of the springs thereof.

The cultivator is provided at opposite sides of the center with fender blades 38, arranged in spaced relation, as clearly illustrated in Figs. 3 and 4 of the drawings, and adapted to prevent the cultivator from throwing the soil upon and injuring the young plants. The fenders are provided at their front ends with arms 29, having laterally extending top portions 40, which are adjustably secured to the front transverse bottom bars 3, suitable perforations being provided for securing the front ends of the longitudinal springs to the said bars 3. This construction permits the fender blades to be arranged the desired distance apart.

The main frame of the cultivator is supported by caster wheels 41, mounted on suitable aXles 42 of approximately triangular frames 43, consisting of a longitudinal top bar 44, depending rear arms 45 and inclined braces 46, extending upwardly from the lower ends of the rear arms 15 to the front end of The front end of the top bar l the top bar 4a. or is provided with a perforation through which passes a vertically adjustable rod 47. The vertically adjustable rod 47, which is mounted in openings of the top and bottom end bars of the main frame of the cultivator, forms a pivot for the triangular frame of the caster wheels. The triangular frame is shiftable transversely of the main frame, and it is provided at its back with an upwardly extending arm or post elS, having its upper end bifurcated and receiving an anti-friction wheel The an frietion wheel is mounted on a suitable axle er spindle 50, and it engages an arcuate track or guide 51, secured to the bottom end bar 8 of the main frame and extending from opposite sides thereof. The anti-friction wheel -19 is adapted to run on the curved track when the triangular frame is shifted in either direction, and it constitutes a fulcrum or bearing for the main frame to enable the latter to be tilted backwardly or forwardly, and it sustains the weight of the cultivator and releases the necks of the draft animals. The terminals of the curved tracks or guides are bent downwardly to form depending steps 51, which are arranged in the path of the anti-friction wheels 50 to limit the relative lateral movement of the caster wheels and to prevent the anti-friction device from leaving the tracks or guides. These curved tracks or guides may be of any desired length, and they may be braced at the terminals by inclined rods or bars, extending upwardly from the guides or tracks to the main frame, or they may be strengthened or reinforced in any other preferred manner.

The lower end of the rod 117 passes through the front end of the top bar or member of the triangular frame, and it receives an eye of the lower end of a rod 53, which connects the front of the triangular frame with an adjusting lever 04. The adjusting lever 5%, which extends longitudinally of the culti vator, fulcrumed at an intermediate point on. bolt 55, which pierces the levcr and the front vertical bar or member 16. The rear vertical bar or member is equipped with a suitable ratchet 56, which is engaged by pawl or d og 57 of the adjusting lever, whereby the latter is secured in its adjustment. A coiled spring 58, which is disposed on the lower portion of the rod 47, is interposed be tween the front of the triangular frame and the lower face of the bottom end bar 8 to facilitate the adjustmentof the cultivator. By raising and lowering the rear end of the adjusting lever, the main frame of the cultivator is tilted backwardly or forwardly on the anti-friction device of the caster wheel frame. This will throw the shovels, or other soil-engaging devices into or out of the ground, and the adjustment may be effected while the cultivator is in operation and without stopping and resetting the cultivating devices. The rear end of the adjusting lever is shaped into a suitable handle 58, and the pawl or dog 57 is also provided with an operating arm or handle 59, arranged adjacent to the grip or handle of the adjusting lever. The front portion of the adjusting lever is provided with a slot 60, through which the vertically movable rod 1-7 passes. The caster wheel enables the cultivator to be shifted laterally for dodging corn or stumps, and also for moving it upwardly while cullivatin on a hillside, whereby the cultivator is prevented from slipping down the hill.

The cultivator is provided with a pair of adjustable handles lSl, mounted on and extending across the space between the top trans, crse bars 1 and 2. The front ends of the handles are secured to the front transverse bar 1 by means of bolts, or other suitable fastening devices, and the intermediate portions of the handles are adjust-ably connectcd with the rear transverse bar 2 by means of angle plates or brackcts 62, secured to the upper face of the said bar 2 and having upwardly extending arms provided with a plurality of perforations 63 for the reception of bolts 64, or other suitable fastening devices By thls construction the handles may be ra Ell or lowered to arrange them to suit either a boy or a man. By pressing down on the handles the cultivator may be tilted on the castcrwhcels to force the cultivating devices into the ground.

The draft animals are hitched to swingletrees 65, which are secured to the lower ends of the approximately vertical levers 66, connected at their upper ends to and depending from an equalizing bar or member (37. The depending levers (56 are connected at an intermediate point with the front vertical bars or members .6 of the main frame by links 6?. The equalizing bar or member is pivoted to the lower face of the draft beam or tongue by a bolt 69, and it is supported by a transverse bar 70, connected with the top of the main frame by a short central brace Tl and with the bottom of the main frame by side braces 72. The :eide braces 72, which are disposed longitudinally of the cultivator, extend across the space between the front and rear bottom transverse bars and are suitably sccurcd to the same to brace the depending sidc portions of the main frame. The front portions of the ln'accs 72 extend upwardly and are secured to the terminals of the supporting bar at the lower face thereof. The equalizing (lOvlCP enables the draft animals, when drawing the cultivator, to move backwardly and forwardly with relation to each other without twisting the (ailtivator.

When it is desired to transfer the cultivator from. one field or place to another, the

cultivating devices are elevated above the ground and the caster wheels are held against lateral movement relative to the main frame. This is effected by means of a transversely disposed supporting bar or bolster 73, designed to be cons JIUOlZGCl of any suitable ma terial and adapted to be interposed between the top of the caster Wheel frames and the bottom of the main frame. The transverse bar or bolster 73 provided at its ends with upwardly and downwardly projecting arms or portions 7e and 75, and they are fitted against the upwardly extending posts or arms 48 of the caster wheel frames. The upwardly extending arms or portions 7 l of the transverse bar or bolster 73 fit against the lower faces of the end bar 8 of the main frame, and they are provided at the outer edges of the latter with upwardly projecting lugs 76. The upwardly extending arms are also provided with projecting studs or pins 77, which fit in perforations 78 of the lower end bar 8, whereby the transverse bar or bolster 73 is detachably interlocked with the main frame. The lower or downwardly extending arms or portions 75 are provided with recesses 79, forming forks or portions, which straddle the lon gitudinal top bar of the caster wheel frames, whereby the latter are interlocked with the supporting bar or bolster 73. The supporting bar or bolster is adapted to hold the cultivating devices above the ground, as clearly illustrated in Figs. 8 and 9 of the drawings, and the caster wheel frames are rigidly connected with the main frame. The supporting bar or bolster is detachably secured to the upwardly extending arms or posts 48 of the caster wheel frames by means of hooks 80, secured to the bar or bolster 73 and engaging lugs or projections 81, located at the outer side faces of the posts or arms 48, but any other preferred fastening means may be em ployed for detachably securing the bar or bolster 73 in its interlocked relation with the main frame and the caster wheel frames.

The cultivator may be equipped with a seat for the accommodation of the driver, and instead of employing the blades 21, other forms of cultivating devices may be used. Also the machine may be equipped with a central cultivating device for use when the fenders are not employed.
