2 Claims. (01. 97-35) The present invention relates to new and useful improvements in plows, particularly of the tractor drawn gang type, and has for its primary object to provide, in a manner as hereinafter set forth, an implementof this character comprising means for removing excess straw, stubble, et cetera, from the path of the plows and depositing it in a position to be covered by said plows, thus preventing choking, while at the same time leaving suflicient straw, et cetera, on top of the soil to prevent erosion.

Another very important object of the invention is to provide a plow of the aforementioned character which may be expeditiously adjusted as desired to meet various conditions.

Other objects of the invention are to provide a plow of the character set forth which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manutured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is atop plan view of a plow embodying the present invention.

Figure 2 is a view in side elevation of the implement.

Figure 3 is a fragmentary view in rearelevation, showing the drive means for the forks.

Figure 4 is a view in side elevation of one of the forks and the supporting means therefor, portions of the latter being shown in transverse section.

Figure 5 is a perspective view of an intermediate portion of the crank shaft.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a plurality of beams I having mounted thereon plows 2. The forward portions of the beams I are rigidly connected, as illustrated to advantage in Figure 1 of the drawings. Suitable means 3 is provided for connecting the beams I to a tractor or other suitable source of power.

portion constituting a spindle I' on which a ground wheel 8' is journaled. 7

Fixed horizontally on theupper, front portion of the plate 4 is a tubular-housing 91 A shaft I0 is journaled in the housing 9. The shaft I0 is driven from the wheel 8 through a chain and sprocket connection I I. A suitable tightener I2 is provided for the chain of the drive II.

Mounted on the beams I is a metallic frame structure I3 comprising a horizontal rod I4 and angular members I5. The members I5 terminate in upturned rear end portions on which a horizontal shaft I 6 is mounted. Vertical tubular guides I! are journaled at spaced points on the shaft I6.

Bearings I8 are mounted on the members I 5 at the angles thereof. A horizontal crankshaft I9, which parallels the shaft I6 in spaced relation thereto, is journaled in the bearings I8. Clamps 20 are journaled on the throws of the crankshaft I9. Forks 2I are adjustably secured in the clamps 20. The forks 2I include tines or heads 22 on the lower ends of shafts 23. The shafts 23 are adjustably secured in the clamps 20 with their upper end portions slidably engaged in the guides A suitable universal joint 24 connects the crankshaft I9 to the shaft II] for actuation thereby. The rod I4 is fixed at one end to the tubular housing 9 to function as a brace therefor.

It is thought that the operation of the invention will be readily apparent from a considera- Fixed vertically on the rear portion of the tion of the foregoing. Briefly, the ground wheel 8 is adjusted as desired on the plate 4 by loosening the clamps 6 to permit the plows 2 to function at the desired depth. Proper tension on the chain drive II is maintained by the tightener I2. As the implement is pulled forwardly with the plows 2 in the ground, the wheel 8 travels on the surface of the ground and is, of course, rotated thereby. Thus, the chain and sprocket connection II rotates the shaft III which, in turn, drives the crankshaft I9. forks 2|, or rather the heads 22 thereof, are caused to described a circular path, the construction and arrangement being such that said forks sweep excess straw, stubble, et cetera, away from in front of the plows 2 to a position where said straw, stubble, et cetera, willbe covered by said plows. The clamps 20 permit vertical adjustment of the forks 2I on the crankshaft I9. The shaft I6, on which the forks 2I slide and oscillate, may also be adjusted vertically, if desired, on the members I5 for adjusting or regulating the stroke of said forks.

In this manner the It is believed that the many advantages of a plow constructed in accordance With the present invention will be readily understood, and although a preferred embodiment of the implement is as illustrated and described, it is to be understood that changes in the details of construction and. in the combination and. arrangement of parts may be resorted to which will fall within the scope of the invention as claimed,

What is claimed is: I I I 1 1. A plow comprising a plurality of beams,

plows mounted on said beams, a frame structure, mounted on the beams, a stationary shaft mount ed horizontally on the frame structure, a crank;,j= ,:j

shaft journaled horizontally on theframe structure below the horizontal plane of the stationar shaft, a plurality of forks slidably and rockably' connected to the stationars shaft, means c'onnecting said forks to the crankshaft for actuation,
