CROSS REFERENCE TO RELATED APPLICATION(S) 
       [0001]    This is a continuation in part, non-provisional patent application based on co-pending U.S. Non Provisional patent application Ser. No. 14/138,693 (Attorney Docket No. ARA-15-1) titled “Row Making Tool”, filed on Dec. 23, 2013, which claims priority to Provisional Application No. 61/716,972 filed on Oct. 22, 2012, the disclosure and contents of all cases, which is incorporated herein by reference in their entirety. 
     
    
     BACKGROUND 
     Field of the Invention 
       [0002]    The invention relates generally to hand tools designed to build straight, uniform, evenly spaced, and proportionally sized row furrows and mounds for planting seeds in a home garden plot. 
         [0003]    Prior to embodiments of the disclosed invention, making garden rows in home gardens was a difficult, labor intensive, and a slow process. There were no easy to use tools designed to quickly create straight, evenly spaced and ready to plant garden rows that would facilitate the seeding process. There have been many attempts to build a tool for such a purpose in the form of a hand operated cultivator. Cultivators however do not create rows as much as they merely till soil. In addition, there are numerous problems that make these types of tools inefficient for building garden rows. 
         [0004]    First, a cultivator is a tool designed to prepare the soil for planting by turning up the soil to remove weeds and grasses by the roots. And further, to remove weeds and grasses by the roots from in between rows of existing crops. To remove any vegetation by the roots implies that the ground must have received sufficient water and must have remained undisturbed for a period of time that was long enough for the grasses or weeds to grow root systems. Thus, the ground had to have become hardened or denser to some extent. To remove grasses and weeds from hardened soil with a hand operated cultivator, a user must possess enough personal strength and stamina in order to push or pull a multi-bladed tool with enough force so that the blades can break through a dense or hardened surface and sink themselves down into the ground while the tool is being pushed or pulled through the soil in a continuous effort. 
         [0005]    Cultivators with typical sharp plow-like blades that point downward like those found in U.S. Pat. No. 1,309,228 are designed to cut into the ground and will tend to snag on roots, rocks, or hard clumps of dirt, which will cause the tool to come to an abrupt stop if a tip snags, or if multiple tips grab the harder deeper soils and the resistance becomes greater than the strength of person pulling or pushing the tool. 
         [0006]    When a multi-bladed hand pulled tool that utilizes a straight handle such as U.S. Pat. No. 1,309,228, gets snagged and embedded in the ground, the tool cannot just be pushed back to free it. The user will have to jerk the tool to try and break the tips free from the obstruction, or, the user will have to manually lift the entire blade assembly out of the ground and then reposition it past the obstruction to continue cultivating. Thus, cultivators with blades such as those disclosed in U.S. Pat. No. 1,309,228 are impractical and ineffective for building multiple, uniform, evenly spaced rows of furrows in straight lines, as they were not specifically designed to do so. 
         [0007]    Second, hand cultivators of the art are not ergonomically designed. In order to get depth of row furrows in multiples, with a tool that has a straight, hoe-like handle like those found in U.S. Pat. Nos. 645,702A, 1,309,228, and 1,414,087 will require a constant downward push of the handle by the user, plus a pulling or tugging effort while the user walks backwards in a body posture that is bent forward and to one side. Repeated motions in this posture are not natural to the human body and will be hard on the nerves and muscles of the lower back, the spine and the arms. Accordingly, balancing and lifting a wide front heavy tool by a straight handle, to turn it to start on a new set of rows, will become difficult as the user will not be able to control the straight hoe like handle from rotating in his hands. 
         [0008]    Third, in order to easily build uniform furrowed rows with proportionally sized mounds, a tool must have a correct balance of design and weight working in synergy, so that all of the blades can sink evenly into the ground while separating the soil in a steady, straight, moving momentum. It has been found that light weight hand tools with straight hoe like handles that are designed with blades made from flat or concaved sheet metal are too light to sink the blades evenly into the deeper soil and are difficult to keep moving in a straight line course. Too few blades will not have enough weight to provide the downward force needed to sink the blades into the soil. Too many blades will have too many points of contact with the soil, thus blades will need more weight for them to sink enough to create the desired effect. Too much weight can sink the blades too deep making them easy to snag while also creating a greater pull resistance which will make the tool harder to pull, harder to maneuver, and harder to lift to turn it around. 
         [0009]    Fourth, there is no hand tool that can uniformly and seamlessly join sets of completed rows in such a way, that when the plot is complete, all of the rows will be proportional in spacing, height, depth and uniformity accordingly making the rows appealing to the eye as well as functional. 
         [0010]    Fifth, existing tools do not incorporate a practical system that will build the types of rows that will provide a platform to the Gardner where after the rows are completed, he/she can visually plan where to best place his/her crop separations in order to separate different varieties of vegetables into groups of long rows, or into neat orderly uniform blocks. 
         [0011]    Last, the process of building rows requires hard manual work and is so time consuming with no easy way to improve or to fix imperfect or damaged rows that usually, in this situation, Gardner&#39;s will feel compelled to plant in the rows they ended up with, no matter how shallow, how crooked or how imperfect the rows turned out. 
         [0012]    U.S. Pat. No. 4,484,635 to Sidlo discloses a garden row making tool which has a pointed blade on one end and a shovel on the other end of a rail. The tool will not produce multiple uniform proportional rows of mounds and furrows for planting seeds. U.S. Pat. No. 5,372,205 to Velez discloses a furrow covering hoe for one-handed operation. Like U.S. Pat. No. 4,484,635, the tool described will not make rows of mounds and furrows. U.S. Pat. No. 3,332,376 to Saunoris et al discloses a row making device which includes lateral and longitudinal runners for forming rows in planting beds. This device is cumbersome and usable at best in small plots of soil. Troy Bilt Hiller Corporation and Brinley Corporation sell blades which attach to an apparatus that is pulled by a powered or motorized machine such as a tractor or tiller. These blades are not attachable to a known hand-operated tool that will assist a user to easily and quickly make multiple uniform rows of uniform mounds and furrows. 
         [0013]    A need continues to exist for a hand tool which can quickly and easily build uniform garden rows consisting of, straight rows of mounds and furrows which facilitate the many facets of planting a garden. Embodiments of the disclosed invention solve all of these aforementioned problems. 
       SUMMARY 
       [0014]    The tool and in particular, blades of the portable, hand pulled, garden row making tool herein described, are configured to rapidly, build sets of rows consisting of multiple, straight, evenly spaced furrows of proportional depth, in combination with corresponding rows of straight, evenly spaced, soil mounds of proportional height, and also, to seamlessly join all of the row sets that were created in such a manner where an observer will not be able to tell where one set of rows ends and the other set begins. The unique tool is designed to make rows that will facilitate the planning and planting of seeds in a garden plot where the soil has previously been machine tilled with a motorized garden tiller to a depth of four inches or greater. 
         [0015]    This practical tool is easy to operate and can used by an average skilled person of teen age years or greater and average strength, to build usable garden rows. To use, once the soil is tilled, a Gardner will place the tool where the first rows are preferred and pull, while walking backwards, the tool through the soil. If the rows created are damaged or are not acceptable for any reason, the rows can be easily fixed or completely re-made with very little time lost. Rows created by the inventive tool give the Gardner the option to plant on the tops of the row mounds or inside the row furrows. The channeled furrows will maximize conservation of available irrigation water by evenly saturating the soil around the seeds and seedlings. The furrows will continue to channel water to the roots systems of the plants during irrigation as they grow and until the plants are ready for harvest. 
         [0016]    Dividing or sectioning off rows created by this tool, into smaller blocks to accommodate different varieties of vegetable seeds is easy to do. The Gardner can plan a more realistic seed layout while actually looking at his plot after all of the rows have been built. 
         [0017]    The disclosed tool is comprised of a wide pull handle assembly that is elongated to over 5 feet in length. The long handle configuration is attached to the center of a rail that holds symmetrical blades. Preferably, there is no center blade located in the middle of the tool. Each blade is designed to work in conjunction with the adjacent blade so that each blade will create one furrow while raising the displaced tilled soil into a proportionally sized mound that will form in between the two blades as the tool is pulled. 
         [0018]    The tool as designed has a preferred weight of about 18 pounds. This is sufficient to build rows in a tilled plot without any added weight, but an alternate feature of the tool provides for support of two weight disks, of up to 10 pounds each, that will be evenly distributed to both sides of the tool blade assembly.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0035]    The inventive tool is portable and can be assembled and dissembled for transport or storage by hand without any additional tools. The tool will make and seamlessly join rows of sets of furrows and mounds that will facilitate the planting of seeds in a plot where the soil has been machine tilled to a depth of four inches or greater. Each blade works in conjunction with the adjacent blade to each create one furrow while raising the displaced tilled soil into a proportionally sized mound of soil that forms in between the two blades as the tool is pulled. 
         [0036]    Referring to  FIG. 1 , a blade  22  is preferably not attached to the center of this tool. The tool comprises detachable T shaped pull handle  10  coupled to shaft extension  12  with wire lock pin  30 . Shaft extension  12  is coupled to rail shaft  14  with wire lock pin  30 . Rail shaft  14  is fixedly attached to rail support bracket  16 . The bracket can be attached by any means known in the act but welded has been found most suitable to fixedly attach to the support. Rail support bracket  16  is attached to rail  18  with hand turn screw  34  that is routed thru a hole in center of rail  18  to nut  36  as shown in  FIG. 5 . In another embodiment, a plurality of nut  36  can be secured such as per welding, on to rail  18  to permit a plurality of blades  22  to be attached onto rail  18  with a plurality of hand turn screws  34 . 
         [0037]    As shown in  FIG. 2 , the complete assemblage of blade  22  is comprised of a channeled L shaped slide bracket  20  that is centered, and fixed to the back of blade  22 , wherein the two pieces are joined and together may be referred only as blade  22 . 
         [0038]    Referring to  FIGS. 2, 3 and 4 , blade  22  can be fabricated from ⅛″ thick steel plate that is cut to a shape of an irregular pentagon and further bent in half at its center to about a 90° angle. The shape of the blade is transformed to a first and second section. The first and second sections are quadrilateral shaped with no equal sides and no parallel sides, and when combined with their respective smoothly rounded common edge CE form an acute angle. That common edge CE of the two sections of blade  22  is angled back to a slant of about 135 to 140°, as measured with a protractor and the blade is placed on a flat surface and measured upward, from the lead point (LP). The slant will pull the blade downward into tilled soil TS to form a furrow F, while dividing and lifting the soil to form two proportionally sized mounds M on each side of the furrow F as shown in  FIGS. 6, 8 and 14 . The two sections at the base of the blade, at their lowest edges, form a hollow triad with an angle of about 65°, and trail outward from the leading point LP to end as the blades two trailing points TP. Those two edges of the triad become the blade skids SK. 
         [0039]    Referring to  FIG. 5 , the channel bracket  20  slides over the angled iron that makes up rail  18  and is secured with wire lock pins  32 . The channel can also be secured with screws or other type mechanism allowing the bracket to be loose or tight. It is preferred that bracket  20  remain slightly loose fitting. This loose fit gives each blade  22  an independent ability to move slightly or jiggle. As shown in  FIG. 7 , as the skids and the two trailing points TP slide over the contours of the lower harder untilled dirt, this slight independent wiggle in plurality causes a vibration in the tool which assists the blades to break through or skip over minor soil obstructions. The vibration will also help to prevent any single blade from snagging or turning the straight line movement direction of the tool. If desired by user, the blades can also be secured tightly with a screw or other means to keep the blade from moving. 
         [0040]    The contact edges of the triad skids SK along with the two trailing points TP will slide nearly flat over the lower harder untilled dirt and serve to prevent the tips of blades  22  from burring and locking themselves into the deeper ground. Small granules of loose soil are forced under the blades and provide lubrication to lessen the drag resistance of blade  22  which allow the tool to be pulled easily. This interaction of blade  22  with the soil makes this tool produce rows extremely fast. In tilled soil a Gardner of average cardiovascular health and of teenage years of age or older can build continuous straight rows of furrows and mounds at an average speed of about 1½ feet to 2 feet per second. 
         [0041]    In an alternate embodiment, a third blade  22  and a fourth blade  22  are connected to rail  18 . First and second blades  22  create two furrows of proportional depth with a joined mound in between them. Second and third blades  22  create two furrows of proportional depth with a joined mound in between them. Third and fourth blades  22  create two furrows of proportional depth with a joined mound in between them. This embodiment having four blades on rail  18 , will create one set of rows consisting of four furrows of proportional depth and three mounds of soil of proportional height. 
         [0042]    To work the inventive tool in soil that is badly cultivated either by hand tools, or by a machine that leaves large clumps of broken dirt, a downward force is needed to form the rows. The downward force upon Blades  22  can be adjusted by adding weight  40  to two support rods  28 . Support rods  28  can be routed thru holes in rail  18  and secured or screwed into nuts  36  as shown in  FIG. 5 , wherein weight  40  can be attached onto weight support rod  28 . 
         [0043]    Weight support rods  28  are configured to each accommodate a weight disk  40  that can weigh up to 10 pounds. The amount of weight added to the tool is dependent on how well the soil has been tilled. In addition, the respective working angle of the leading point of blade  22  can be changed by lifting or lowering the T-pull handle  10 , wherein the two trailing points TP will serve as fulcrums to lift the tips of blade  22  upwards while supporting the added weight. 
         [0044]    Referring to  FIG. 1 , the ergonomic T-handle  10  is constructed of 1 inch steel tubing that can be at a length from 20 to 22 inches to be equally divided on each side from the tools center shaft. The T handle is secured to handle support shaft  12  for example by welding, and further secured with corner supports fabricated from 2 inch flat stock. While steel is the preferred material for the tool and in particular the handle, other materials can be used for making the tool. For example, other metals such as galvanized pipe, aluminum, sturdy plastic, fiberglass, wood, and combinations thereof. The handle can be the same or a different material than the rail and blades without limiting the utility of the invention. It is recommended, but not mandatory, that the material chosen be of a rust-resistant nature. 
         [0045]    T-handle  10  is perforated with a lower handle shaft hole. Shaft extension  12  comprises an upper shaft hole. Wire lock pin  30  can be inserted through the lower T-handle shaft hole, and the upper shaft extension  12  hole to join and secure the two shafts together. 
         [0046]    Shaft extension  12  further comprises a lower shaft hole. Similarly, rail shaft  14  comprises an upper rail shaft hole. Wire lock pin  30  can be inserted through the lower shaft extension  12  hole and the through the upper rail shaft  14  hole to join and secure the two shafts together. Alternatively, the shaft can be of a telescoping design with standard lock mechanism known to those of skill in the art. 
         [0047]    In considering fatigue or injury to the users lower back, T-handle  10  is configured to comfortably divide the pull effort equally to both hands and arms so that the user pulls with a straight body posture thus shifting the hardest work effort to the leg muscles which will provide most of the strength required to work the tool. The two wide point grip position of the user&#39;s hands as demonstrated in  FIG. 8 , together with the wide set ground contact of the plurality of blades  22  stabilize the tool, giving the user a safe, steady handle to hold with both hands as he/she builds garden rows. The handle can be optionally cushioned with grips for increased comfort during use. It can also have a non-slip grip type of covering on the handle. 
         [0048]    The connecting point between rail support bracket  16  and rail  18  becomes the tools&#39; center of balance. The total working length of the tool including T-handle  10 , the shaft extension  12  and the rail shaft extension  14  can be between 4.0 feet to 7 feet in length. The length can vary upon user&#39;s preference with a preferred length of 5.5 feet to 6 feet. 
         [0049]    A straight line pull is naturally achieved by the elongated shafts of the tool working in synergy with the resistance and the equilibrium effect of blades  22  as they are dragged (while user is walking backwards) thru the tilled soil TS. The result is that the tool will follow the user&#39;s desired direction. A shift of the T-handle  10  to the right or to the left will turn the direction of rail  18 , which gives the user an ability to make corrections to the straightness of the rows as he pulls the tool as shown in  FIGS. 6 and 8 . 
         [0050]    When working the tool in rough or course soils such as moist tilled clay, the slant angle of blade  22  can be adjusted to drive the tips of the blades further into the soil by lowering T-handle  10 . A lift and a twist of T-handle  10  can cause the blade  22  to turn upward and or to the side so that the tool can be maneuvered over or around obstructions without having to lift the entire blade assembly. 
         [0051]    The inventive tool is configured with an even number of blades  22  which are spaced evenly along the rail, with the center space left open or blank and is used to form the rows of mounds. The inventive tool does not have a blade  22  attached to the middle or central point of the rail. A first blade  22  and a second blade  22  are connected to the right and to the left of the center point of rail  18  and are configured to create furrows F to the right and to the left of center while simultaneously creating one mound M of soil that will be left raised and centered between the two furrows F at the middle point of the tool, as shown in  FIG. 6 . 
         [0052]    The placement of two blades  22  to the right and to the left from the center point of rail  18  is significant in that a user can re-work the tool over any rows to deepen furrows F, to heighten mounds M, or to correct damage or imperfections to the rows while naturally walking inside the two furrows F to the right and left of the tools center. Thus, the user will not step on the existing mound M that runs under the tools center point, as demonstrated in  FIG. 8 . If when completed, any of the rows are not acceptable for any reason, the rows can be fixed or improved without damaging existing mounds, or all rows can be completely re-made with very little time lost. 
         [0053]    While two blades  22  and four blades  22  are preferred for the tool described it is possible to incorporate an odd number of blades  22  into the tool; this is at user&#39;s discretion. There may be some adjustment of the pulling mechanism required of the tool with an odd number of blades on the rail. It is also recognized that more blades  22  can be added by adjusting the size of rail  18 . 
         [0054]    Another significant feature of inventive tool is found in the turning of the tool to face it in the opposite direction so as to build a new set of furrows and mounds after one set has been completed as shown in  FIGS. 6 and 9 . By using the leverage of the wide T-handle  10 , the user can easily twist and pivot the tool on either of the outer blades  22  in order to rotate it to the opposite direction. The tip of the pivot blade PB will support the heaviest weight of the tool as it is turned around, thus eliminating the need to manually lift the multiple bladed tool to turn it. As shown in  FIGS. 6 and 9 , as the tool is turned, the tip of pivot blade PB will spin inside the furrow that it created and will automatically align and center itself into a ready position when the turnaround is completed. The end blades in the rail serve to also be the pivot blades during use of the tool. 
         [0055]    The independent movement of each blade assists in pivot action for turnaround of the tool in the opposite direction. 
         [0056]    The user can start the next set of rows without having to re-position or re-align the blades. As the next set of furrows are started, the tip of the pivot blade PB will drag in a straight line inside the deepest part of the furrow that it created, which will serve as the straight line guide for the new set of rows. When the process is repeated, all sets of furrows and mounds will run parallel and uniform with each other and will be seamlessly joined in appearance, proportionality, and function as shown in  FIGS. 14 and 15 . 
         [0057]    This pivot turning feature makes this inventive row building tool extremely efficient. In tilled soil the average turnaround time for a Gardner in good health and of teenage age years or older, and of average strength is about 8 to 12 seconds per turn. 
         [0058]    To demonstrate the tools&#39; efficiency while building rows in a 40′ long×30′ wide garden plot, a Gardener in good health was able to build 33 rows in the tilled soil for the plot as follows: 
         [0059]    Female, 30 yrs, 5 minutes, 20 seconds; 
         [0060]    Male, 32 yrs, 4 minutes, 15 seconds; 
         [0061]    Male, 57 yrs, 4 minutes 22 seconds. 
         [0062]    To work the tool in limited spaces, an alternate embodiment is shown in  FIG. 12  where T handle  10  is directly connected to rail shaft  14 . It may be preferable to omit shaft extension  12  and connect T handle  10  directly to rail shaft  14  by inserting wire lock pin  30  through the lower T-handle  10  shaft hole and the upper rail shaft  14  hole to join and secure the two shafts together. 
         [0063]    While the handle has been described as a T handle, an alternate type of handle such as D handle  FIG. 11 a   , can be used with the inventive tool. It has been found that a D handle works well in conjunction with a two blade  22  configuration or for a smaller version of the tool for use in small gardens. This does not limit the tool with a D handle to only two blades. The D handle can be used with more than two blades on the rail  18 , but it may require more strength and dexterity to use the tool than. 
         [0064]    While the wire lock pin is described herein for making the tool easy to assemble, alternatively, the tool can have the T handle and shafts permanently secured if desired. 
         [0065]    While explained as a portable, hand-assemble-able tool, if desired, all parts of the tool can be permanently attached. 
         [0066]    As shown in  FIG. 13 , in a further alternate embodiment, blades  22  can be removed from rail  18  leaving only T handle  10 , shaft extension  12 , rail shaft  14 , and rail  18  with attached weight support rods  28 . By adding optional weight disks  40  to the weight support rods, the tool can function as wide soil drag to smooth out the tilled soil prior to building rows. 
         [0067]    As shown in  FIGS. 14 and 15 , after the rows have been completed, the rows of mounds and furrows are ready for immediate planting. The Gardner can divide the plot in halves or in quarters with a bow rake. The Gardner will have the option to plant in straight lines inside the rows of furrows or over the tops of the elevated soil mounds. He/she can neatly separate plant varieties with walk paths created by raking down one row between seed lines. Distance between plant rows can be uniformly increased by skipping one or two rows between lines of seeds. 
         [0068]    As described the preferred tool has the following dimensions: 
         [0000]    
       
                 
         
             
             
         
       
     
         [0069]    4-Blades spacing 10 inches apart on the rail with no center blade wherein the preferred blade comprises 
         [0070]    CE=5.5 inches 
         [0071]    TP to LP=4.5″ 
         [0072]    TP to TP=5.5″ 
         [0073]    TP towards support rod  20 =3.5″ 
         [0074]    TP to TP=5.5″ 
         [0075]    Angle at LP=about 65 degrees at lower rounded blunt edge 
         [0076]    Slant of CE=approx. 135-140 degrees 
         [0077]    This design has been found to be comfortable to handle and maneuver through tilled soil. However, it is recognized that the tool can be resized to become increased or reduced in a proportionate fashion. Likewise, as mentioned previously while 2-4 blades are preferred for making 2 or 4 rows of mounds and furrows, 6 blades may be used on a longer rail. A further alternate design involves the spacing between the blades. While a blade spacing of 10 inches on center is preferred, the spacing can be anywhere from 3 to 7″ so as to adjust the height and width of the mounds. The preferred tool will produce mounds and furrows having about a 10″ spacing from the center point mound to mound, before watering the soil. Thus one skilled in the art can see that placing the blade in a different position on the rail will alter the height and separation of the mounds. 
         [0078]    Persons of ordinary skill in the art may appreciate the standalone capabilities of the unique Garden row building tool placed isolated from others by its own merits, and enjoy the functional benefits of the inventive systems. Thus, given the embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
