7 Claims. (Cl. 172-252) 'Matter enclosed in heavy brackets original patent but forms cation; matter printed in made by reissue.

The present invention generally relates to a device for shaping and forming plant beds and more particularly to such a device for forming and shaping a raised plant bed of various sizes and for composting the sides of the beds so that precise furrows are provided between raised bed rows with the furrows acting as means for conducting irrigation water between rows adjacent to the plant roots, the device being normally drawn behind a Wheeled tractor of the type conventionally employed on farms and `which 1s usually provided with a hydraulic power system, a power take-oit and a power lift mechanism, the Shaper being somewhat in the nature of a Sled drag which not only shapes the seed bed rows and compacts the sides of t/ze beds, but also Shapes the furrow for providing a uniform size of seed bed and uniform size of furrow between the adjacent rows of seed bed.

Another object of the present invention is to provide a seed bed forming and shaping device in the form of a drag sled adapted to be pulled by a tractor which will not only form a seed `bed with a smooth top surface, but also a raised seed bed with a peak therein commonly known as a salt ridge.

A further important object of the present invention is to provide a plant bed Shaper incorporating conventional structural component parts which will not only accurately form the slope side `walls or side surfaces of a plant bed but which `will also accurately and positively form the top surface thereof for receiving the seed or Seedlings.

Yet another feature oi the present invention is to provide a plant `bed Shaper in accordance with the preceding objects `which is simple in construction, provided with a minimum of moving parts, adaptable `for use in forming different sizes and shapes of seed `beds and generally inexpensive to manufacture and maintain.

These together with other objects and advantages 'whic 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 iilte parts throughout, and in which:

FIGURE 8 is a longitudinal, vertical sectional view taken substantially upon a plane passing along section line 8-8 of FlGUiE 4 illustrating the details of construction of the Shaper and illustrating the removable plate for forming either the llat type raised plant bed or the peak type raised plant bed; and

appears in the no part of this reissue speciliitahcs indicates the additions FIGURE 9 is a transverse, sectional view taken substantially upon a plane passing along section line 9-9 of FIGURE 4 illustrating the structure of the plant bed shaper and particularly the means for adjusting the width oi the plant bed.

Referring now particularly to the drawings, the numeral lil generally designates the plant bed Shaper of the present invention which is illustrated as being drawn by a tractor 12 of conventional construction and of the wheel type. Fthe shapcr it] iS provided for forming a raised seed bed Ll having inclined or sloping side surfaces 16 and a ilat top surface 18 for receiving two rows of seedlings 20 or seed from `which the seedlings will sprout. Between the plant beds 1d is `a llat bottom furrow 22 which will receive irrigation water for providing water adjacent the roots of die plants or seedlings 2i). In FIGURE 6, there is illustrated a different type of plant bed which is designated by the numeral 2-4 which includes the saine sloped side surfaces 26 and a flat top surface 28 but with the iiat top surface 28 having a peak or ridge 30 therein which is commonly referred to as a salt ridge. Other than this salt ridge Si), the plant bed 24 is the same as the plant bed lvl.

Referring now specifically to FIGURES 4-9 of the drawings, `it will be Seen that each plant bed 14 or 24 is formed by a Separate plant bed Shaper generally designated `by the numeral 32 and it is pointed out that several of these plant bed Shapers may be connected together in an aS- sembly `lil such as that illustrated in FIGURES 1 and 2.

Each shapcr 32 includes a generally laterally extending top plate 34 having a moin section which inclines upwardly and forwardly. |The forward edge of the moin section of top plate 34 is turned upwardly and the upturned front fedge] portion is designated by the numeral 36. The front `{edge} portion 36 is inclined in relation to the horizontal and is in acute angular relation to the horizontal surface formed by the Shaper. The rear edge of the main section of t/ze plate 3-i is also turned upwardly, this edge being designated by the numeral 38 and generally extending in a perpendicular manner to the moin section of the top plate 34.

Disposed centrally in the moin section of the top plate 34 is an inverted V-shaped ridge generally designated by the numeral 4t) and defined by a pair of upwardly inclined plates 42 and 44 joined along the ridge 46. The ridge 46 extends in a downwardly sloping relation from the front to the rear of the main section of the plate 34, the front edge thereof being generally coincidental with the top edge of the upturned edge of portion 36 and the rear edge thereof being disposed below the top edge of the upturned rear edge 38. The upturned rear edge 38 is also provided with an inverted V-shaped notch 4S corresponding to the opening of the rear edge of the ridge 40 and the upturned {plate} portion 36 is also provided with an opening Sil corresponding to the front edge of the opening delined by the ridge 40 where it intersects the plate 34.

Forming a closure for the bottom of the ridge 40 which bottom opening is dencd by thc reference numeral 52 is a plate 54 of the same size and conguration as the opening 52 in the main section of plate 34 and also the opening 50 in the upturned [edge] portion 36. The plate 54 is provided with a pair of bolts 56 welded or otherwise rigidly secured thereto, the bolts 56 extending upwardly through the ridge 46 and being provided with nuts 58 on the upper end thereof for detachably securing the closure plate 54 in position. When the closure plate 54 is in position, the undcrsurface of the upturned [edge] portion 36 and the undersurface of the main section of top plate 34 are smooth as illustrated in FIGURE 7 thus forming the smooth top ridge 14. However, when the nuts 58 are loosened and the plate 54 is removed, the shaper will then form the seed bed with the ribs 30 3 therein, this seed bed being illustrated in FIGURE 6 with the peak or ridge 30 being formed by the inverted V-shaped recess or ridge 40. Thus by placing the plate 54 in position or removing the same, the shaper may be used to form either the at top seed bed 14 or the ridge or peak type seed bed 24.

Each side of the main Section of the top plate 34 is connected to a side member 60. Each side member includes a pair of [wings] wing sections 62 having inclined trailing portions 64 and outwardly flared forward portions 66, each of the outwardly flared forward portions 66 having a forwardly extending triangular portion 68 with an inclined forward edge 70. As illustrated in FIG- URE 7, the triangular portions 68 extend substantially in parallel relation and forwardly of the leading edge of the upturned [edge] portion 36 of the plate 34. The outwardly ared portions 66 are generally disposed vertically and flare outwardly in such a manner that they diverge from the side edges of the upturned edge 36, but the tlared portions 66 also include an upwardly inclined top edge 72 generally conforming to the contour of the upwardly flared or upturned front edge portion 36 thereby guiding and gathering the soil so that it will pass into the interior of the shaper. The main body portions of the [wings] wing sections `62 are also vertical and are angulated inwardly or in rearwardly converging relation. The trailing portions 64 are inclined upwardly and inwardly and extend under the main section of the plate 34. Each of the side members 60 is adjustably attached to the plate member 34 for varying the width of the seed bed to be formed.

The means for attaching the rear portion 64 of each side member 6i) to the iplate 34 is an Lehapcd bracket 74 rigidly secured to the outer surface of the trailing portion 64 with the horizontal leg thereof having a slot 76 for receiving a fastening bolt 73 therethrough. The fastening bolt 73 also extends through one of a series of laterally spaced openings 80 in the plate 34 thereby varying the position of the trailing portion 64 of the side member 69 in relation to the rear edge of the top plate 34.

For adjustably supporting the forward end of the wing [member] section 62 to the plate 34, the wing [member] scc-tion 62 is provided with an inwardly directed lug 82 which underlies the surface of the moin section of the top plate 34 and is secured thereto by a fastening bolt 84. The fastening bolt 84 extends through one of a series of laterally spaced openings 88 in the main section of the top plate 34 thereby forming means for adjustably securing the front of the side member to the plate 34. Thus, by adjusting the position of the bolts 73 and 84, the position of the side members 60 in relation to the top plate 34 may be adjusted. This adjustment provides the formation of plant beds of different widths with the shaper forming either of two aforementioned types of plant beds.

In operation, the forwardly diverging or outwardly' flared portion 66 as well as the portions 68 gather in the ridged soil which has been previously formed generally in cultivated ridges by a cultvator and plow for the same purpose. The Shaper gathers this material and partially packs and smooths off the plant bed. The converging relation of the [wings] wing sections 62 and the trailing portions 64 compacts the side surfaces of the plant bed while the downwardly inclined construction of the top wall 34 compacts the top surface thereof and forms either a flat top surface or a top surface with a salt ridge 30.

The upturned edge 3S is provided with a pair of apertured lugs 90 and a pair of opstanding attachment flanges 92 are provided intermediate the side edges of the plate 34 and the ridge 40 formed therein, the attachment angcs 92 extending upwardly and engaging the inner surface of the upturned edge 36 thus acting to rigidity the entire Shaper. Thus, a series of the Shapers 32 may be supported in an assembled relation and form a Shaper assembly for towing behind the tractor 12. For forming the assembly, there is a pair of transverse frame members 94 having a plurality of depending brackets 96 arranged in longitudinally spaced pairs for attachment to the flanges 92. The transverse members 94 are rigidly interconnected by a pair of longitudinal frame members 98 and the entire assembly is then attached to a conventional three point hitch mechanism generally designated by the numeral 10i).

Supported from the apertured lugs I are mounting plates 102 carrying a seed or fertilizer hopper 104 which includes a dispenser mechanism 106 with an operating shaft for dispensing seed or fertilizer through a discharge tube or tubes 168 into a planting shoe or chute 11i). The dispenser mechanism 106 is powered by a drive chain 112 driven from a lay shaft i114 supported on upstanding brackets 116 which are carried by a transverse frame member 118 supported on the lugs 9i). A ground engaging drive wheel 120 with projecting studs 122 thereon is supported between a pair of trailing arms 124 pivotally supported from the lay shaft 114 and the ground engaging drive wheel 112 drives the lay ishaft 114 through a sprocket chain 126 and suitable sprockets. Also, spring means may be provided for urging the arms 124 downwardly for engaging the drive wheel 120 with the ground. Thus, with the present invention, there is provided a plant bed Shaper adapted for single or gang use and adapted for ease of assembly into gang use whereby a multiplicity of plant beds may be simultaneously shaped and planted whether the bed to be formed is of the conventional iiat top type or of the type having a peak or salt ridge therein.

The particular structure and contour of the Shaper provides for the gathering and crowding of the loose soil into the device as it is drawn in the direction of travel, the soil being further compacted by the trailing wing [portions] sections with the size and shape of the bed being formed being capable of variation.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
