BRUSH-PLOW.

Specification of Letters Patent. Pattgntd Maty 3Q, 1916.

Application led July 7, 1915. Serial No. 38,412.

To all whom t may concern Be it known that I, MORGAN C. FRENCH, a citizen of the United States, residing at Craig, in the county of Moffat and State of Colorado, have invented certain new and useful Improvements in Brush-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in brush plows, and is more articularly an improvement over my former atent No. 1,153,213, issued September 1%, 1915, and my Object is to provide suitable disintegrating disks in Connection with the plow and means to rotate the same.

A further object is to provide means for clearing a path for the main' driving wheel. And a further obj ect is to provide means for regulating the operation of the mold board.

Other objects and advantages will be hereinafter set forth and more particularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application, the gure is a perspective view of parts of a brush plow, showing my improved attachment applied thereto.

In the drawings 1 indicates a beam of any preferred construction, depending from which are standards 2 and 3, the lower ends of said standards carrying a land side Ll, the forward end of the land side being tapered downwardly to a point and carrying a mold board 5.

Extending rearwardly from the rear edge of the mold board 5 are a plurality of ngers 6 which are adapted to carry portions of the soil and roots, brush and the like,

loosened by the mold board into the path ofv a plurality of cutting disks 7, which disks are adapted to disintegrate the solid particles of the soil and to out into short lengths roots, brush and the like comingin contact with the disks.

The disks are mounted upon a shaft 8, which extendstransversely of the path of the mold board, and there is preferably a disk positioned between each pair of fingers, theshaft 8 being mounted in a suitable supof the section 14 having a universal oint 19 which connects the section 14 to a socket member 20. The section 21 of the tumbling shaft 12 also extends through a bearing 22 on the standard 3 in additionto extending through the bearing 13, the end of the section 21 having a universal joint 23 which connects the same to a section 24, said section 24; having a squared portion 25 which connects with the square opening of the socket member 20 and isadjustable therewith so that the raising and lowering of the mold board andy parts carried thereby will not interfere with the Operation of the tumbling shaft.

Rotatably mounted in the rear end of the.

auxiliary beam 18 is a drive wheel 26 which has attached thereto a cog wheel 27 which meshes with a cog wheel 28 attached' to the shaft 29 carrying the driving gear 17,r

and it will be readily seen that as the plow travels forwardly, the driving wheel will impart rotating motion to the disks 7 through the various gears and tumbling shaft as described.

The operation of the various gears is controlled through the medium of a gear shifting lever 30 which may be constructed in any preferred manner for shifting one'of the gears out of mesh with its cooperating gear to stop the operation of the disks 7. y

'Ihe forward end of the auxiliary beam 18 is pivotally attached to the beam 1 adjacent the forward end thereof, said auxiliary beam extending through a link 3l carried at the rear end of the beam 1, the lower end of said link having an arm 32 to which is attached one end of a coil spring 33, the opposite end of said spring being attached to a hanger 34E carried by the auxiliary beam 1, the tension of said spring being such as to normally hold themold board at a proper level and provide yielding movement of the soV mold board with respect to the auxiliary beam, so .that when an obstruction is en' countered, the mold'board may arise or descend without affectingthe rear end of the auxiliary beam.

Y In order to.V positively board to disengage the same from the soil, a lever y35 is pivotally attached to' the auxiliarybeam 18, one end of said lever being attached to the arm 32 of the link 31 by means of a rod 36, oneY end of which is'pivotally attached to the end of the lever and the opposite end pivotally attached to the arm 32, and it.` will be readily seen that when the free end of the lever isthrown downwardly, the rear end of the beam 1 and the. mold board carried thereby .willV be elevated. f 1

, In orderftopiovide a solid foundation for thetravel ofthe drive wheel 26, a sub mold board37 is attached to the .land 4side 4 adj acentfthe rear end thereof, saidsub mold board Vtraveling inthe rear of themold `board 5l so Y as to encounter the soil loosened by the mold boardV to 'move the'soil out of the path of the f Vdriving wheel, the sub mold board having a rearwardly extending shank 38 between whichand theouterfe'nd of the subA mold board is extended a brace 39.

To insure that noiforeign particles, such as brush,'trash, and the`like',will come inengagement with Y the drive wheel 26 or Vthe gearcarried thereby,1a shield 40 is placed fsa .forwardly of the p ydrive wheelV and at an angleV tothe path ofthe plow, the upper end lof Ythe Vshield'being attached to the auxiliary beamV 18, while `thelower isjattached toV theY shankr38: l

The colter is also provided with a pair of wings 49 which extend rearwardly and outwardly from the colter and are adapted to separate the brush or other obstructions and move the same out of the line of the path of the cutting bar or colter 50 attached to the land side and beam adjacent the forward edge of the mold board,

thus preventing any foreign particles from coming in contact with and collecting againstrthe cutting bar or standards.

`This form of plow is adapted primarily for use in loosening soil having growing lbrush and shrubbery thereon, and in operation .the free end of the lever 35 is thrown' upwardly, thus lowering the mold board 5 in position to enter the soil. The plow is then moved forwardly through any suitable source, the colter 41 severing the roots and brush in advance of the mold board, and moving Vparticles thereof above the soil to one side of the path of the cuttingbar and standards of the plow, while the mold board loosens the soil to the `width of the mold board, the forward travel of the plow causing'the soil, so loosened, to travel over the lingers 6xand into engagement with the plurality of disks 7 mounted therebetween. As

the sub mold board 37 andthe shield 40 andV removed .to one side of the path of the drive wheel 26 so that said drive wheel will rest upon the solid bottom of the furrow, thus causing the wheel tov positively rotate as the plow is moved forwardly. K

When the plow is to be-moved from place ltoV place, the lever 35 is thrown downwardly Vuntil the'plow is movedtoa point above the soil, and said lever may be secured in itslowered position inl any suitable manner,

thereby Vholding the plow out of engagement with the soil until the lever is again elevated. Y' Y v Having thus fully described my invention what I yclaim asl newV and desire to secure by Let-ters Patent of the United States is 1; In vaplow of the class described, the

combination with a mold board, cutting disks ooperating with said mold board, a driving wheel, and means eoperating with the driving wheel and disks to rotate said disks, of a sub-mold board in the path of the first mold board adapted to remove the soil loosened by the first mold board from the path of the driving wheel.

2. In a brush plow, the combination with a beam and a mold board carried thereby, of an auxiliary beam pivoted at one end to said first beam and adjacent the forward end thereof, a driving wheel carried by the auxiliary beam, a link carried by the rst beam through which said auxiliary beam extends, a resilient connection betweensaid link and the auxiliary beam, and a lever for elevating the first beam and the mold board carried thereby. t

3. In a brush plow, the combination with a mold board and a driving wheel in the path of said mold board, of a sub mold board between said driving wheel and first mold board, and a shield forwardly of the driving wheel adapted to remove rubbish women of thm patent may be obtained for and the like from the path of the driving wheel.

4;. Inl a brush plow, the combination with a beam and a mold board carried thereby, of an auxiliary beam pivotally secured at its forward end to the forward portion ofV the first beam, a driving wheel Carried by the auxiliary beam, a link attached to the rear end portion of the rst beam through which said auxiliary beam extends, an arm at the lower end of the link, a hanger on said auxiliary beam, a spring connecting said hanger and arm to resiliently support the rear end of the beam, and a lever connected to said arm and pivoted to the auxiliary beam to raise said first beam and the mold board carried thereby.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
