(Cl. 97-170) This invention relates to farm machinery in general, and has reference in particular to du plex or twin straddle-row structure character- ~ ized by a plurality of systematically arranged knives and foot-type plows. In carrying out the principles of the inven tion, I have adopted an open-type, multiple beam, horizontal framework, this supported on longitudinally spaced straddle-row sled-like car » 2 l and 2v observing same in the direction from either right to left or left to right. Figures 5 and 6 are detail sections on the planes of the lines 5-5 and 6-45, respectively, of Figure 2. 7 ~ Figure 7 is a perspective view of one of the carriages per se. , Reference being had to the drawings by dis riages, said carriages supporting the framework, 10 tinguishing _ reference numerals, and generally observing the structure, it will be seen that (see said framework embodying a plurality of de pending supports for two distinguishable gangs of plows, a main gang along the rear trailing edge of the frame structure, and an intermediate or Fig. 4 for example) each carriage is denoted ‘by the numeral 8. The superposed open Work frame structure is indicated generally at 9. The plows intervening gang trailing the carriages and rear 15 forming the rear trailing gang are denoted by the numerals'l? and those forming the intermediate wardly diverging pulverizing knives mounted on or central gang are distinguished by the refer the frontal end portions of said carriages. Although appearing structurally complicated, the overall structural assemblage is in reality comparatively simple in that, generally speaking, two carriage units support the frame and the frame directly and indirectly supports the sys tematically organized rear and intermediate rows of plows forming the rear and intermediate gangs, all of the ground working implements being on the same horizontal plane. : ence numerals ll. As shown in Figure '7, each carriage comprises a pair of spaced parallel ground-riding runners 52 whose forward ends are beveled, as at I 3, to readily traversev the surface and to ride over weeds and rough ground. Spaced inwardly fromv the frontal ends and rising vertically are uprights Ill having their upper end portions l5 laterally di rected and secured together against the spacing attaching elements l6. Thus, we have arches, Novelty is predicated upon the horizontal and these arches are bolted together at I? and . framework characterized by a plurality of par suitably secured to the under side of the frame allel angle‘ irons connected together by trans verse horizontal bracing members, certain of said 30 structure. The inner or rear ends of .the runners are directed upwardly to provide additional up bracing members constituting supports for the rights [8 braced by an intervening bolt l9. I-lor plows in the so-called rear trailing gang. izontal adapter braces 20 are secured to the up Further novelty is predicated upon the car rights It and i8 and have‘their rear end por riage units themselves, each characterized by runners with appropriately braced means for 35 tions diverging and?aring outwardly, as at 25.. The runners l2 serve to support a pairof com attaching same beneath the main frame struc ture, vand each including rearwardly ?aring brace arms serving at their rear ends as anchors or supports for the smaller plows forming the in termediate or central gang. Other features and advantages will become more readily apparent from the following de scription and the accompanying illustrative drawings. . In the drawings, wherein like numerals are employed to designate like parts throughout the same: Figure 1 is a front elevation of a cultivator and ground-working machine constructed in accord panion rearwardly diverging, suitably propor tioned and shaped knives or cutting blades 22. These are horizontal and terminate at their rear vends at the approximate longitudinal center of ' the machine. The aforementioned plow units II are mounted cnthe rear diverging end por tions of the adapter braces 20, as indicated at the point 21. . . . Considering now the frame structure 9, this comprises, essentially, three horizontally disposed angle irons 23, 24 and 25, respectively. All of these are disposed in the same horizontal plane. The two angle irons 24 and 23 are of the same length, and the rear one 25 is longer and has its ance with the principles of the present invention. 50 end portions extending equal distances beyond Figure 2 is a top plan View of the same. the corresponding ends of the irons 23 and 24. Figure 3 is a horizontal section taken on the The frame structure also includes transverse sta plane of the line 3—3 of Figure 1 looking in the bilizing and assembling plates 26, these being direction of the arrows. Figure 4 is an end elevational view of Figures 55 bolted at their forward ends to the angle iron 23, as shown to advantage in Figure 2. These plates 2,405,796 e, have their rear end, portions bifurcated and the furcations are differentiated by the numerals 21 and 28, respectively. The short furcations 2'! connect or bolt to the angle iron 24. The longer furcations 28 bolt to the intermediate portion of the rear or trailing angle iron 25. I next call attention to the rods 29 and 30-30 (see Fig. 2), the rod 29 extending transversely across the cen tral part of the frame and being bolted thereto, the rods 30 being at the ends of the angle irons 23, 24 and 25, and secured in any suitable manner, 4 the series of three rods 29 and 30, is another phase of the invention worthy of consideration. A careful consideration of the foregoing de scription in conjunction with the invention as il lustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suffi cient to clarify the construction of the invention as hereinafter claimed. Minor changes in shape, size,- materials and re ‘ arrangement of parts may be resorted to in actual practice so long as no departure is made from the rear end portions 3| of said rods being di- ‘ " the invention as claimed. rected laterally outward and bolted to the ex treme outer ends of the angle iron 25. The plow feet 32‘ (of which there are three) form the so-called rear trailing gang, They are detachably bolted to the lower ends of 'the'rela-' tively tall shanks 33, these being secured by, ap I claim: »l.

On the other hand, the smaller plows 35 2.
