Application m Deceiiiber 3,1906. Serial No. 346,181.
To all, whom it 77mg concern:
STRONG, of Avonmore, in the county of Stormont, Province of Ontario, Canada, farmer, have invented certain new and useful Improvements in Plows, of which the following is a specification.
My invention relates to improvements in plows, and the objects of my invention are to devise a plow particularly adaptable for use on rough or unbroken'ground which will make a cut of constant depth independent of any unevenness in the ground and which when striking a stone or other obstacle will tilt and thus lessen the force of the blow, further objects being to provide means for adjusting the supporting and guiding wheels whereby any permanent unevenness in the ground may be counterbalanced; and it consists essentially of the improved construction hereinafter more particularly described and specifically set forth in the accompanying claims.
v Figure 1 is an elevation of my plow. Fig. 2 is a plan view of the same. Fig. 3 is a detail of the means for adjusting the wheel on the crank end of the axle bar. Fig. 4 is an enlarged perspective detail of the connection between the plow beam and the axle bar- In the drawings like letters of reference indicate corresponding parts in each figure.
A is a plow beam of usual construction and B is the plow which downwardly extends from the rear of the. plow beam. The plow beam has a handle asecured to the rear thereof for convenience in tilting the same as hereinafter explained.
C is the axle bar which is connected to the beam substantially at the center thereof whereby both sides thereof will be evenly balanced. The connection between the beam and axle bar as shown in detail in Fig. 4, consists of a vertically extending which bears on a portion of the bracket c.
An arm f is secured to or formed integral with the ring and outwardly extends therefrom, the said arm being connected by a rod 9 to a lever h pivoted to the plow beam in a convenient position to be operated from the position by a latch 11 engaging an are 3'. Thus by movement of the lever h the ring (1 may be revolved about its pivoting point which will raise or lower the beam relative to the axle bar.
with the crank it at one end thereof.
In accordance with my invention each of the wheels D and E is adjustably secured. to the axle. This connection is slightly different for each wheel. For the wheel E it comprises a lever Z which journals the end of the axle intermediate of its length and has secured at its extremity a stub shaft m on which the wheel E is supported. The lever is held in any adjusted position by means of a latch n engaging an are 0 secured to the axle. By this means the wheel m may be tilted forwardly or rearwardly below the axle without raising or lowering the plow appreciably. This adjustment I find to be of advantage when stones or other obstacles are encountered as the wheel may be raised over them. I
The connection between the axle and the wheel D as shown in detail in Fig. 3 consists of a lever p, the end of which journals the axle'which has an off-set or crank g at substantially right angles thereto in the end of which a stub shaft 1" is secured which supports the wheel D. As before the lever is held in any adjusted position by the latch s co-acting with the are 25 secured to the axle. The wheel D is therefore adjustable vertically. This adjustment will be found extremely useful when plowing near the end of a field or along a continuous ridge where one side should be higher than the other. As usual the tongue or pole F is connected to the axle b by a bracket a.
It will thus be seen that in my plow the point of the plow lies substantially under the point at which the beam is pivoted causing it to very readily tilt when encountering obstacles. The depth of out taken by the plow is always constant since it is the difference in depth between the beam of the wheels and the point of the plow. The supporting wheels accommodate themselves to any irregularities in the ground causing the plow to do likewise. The depth of cut may be regulated by the adjustment of distance provided for between the plow beam and the axle bar.
I- have found that a plow such as I have j rear of the plow and held at any adjusted- Be it known that 1, ROBERT ALVEN ARM- The axle bar C is of the usual construction have described with great particularity of detail one specific embodiment of my invention yet certain changes might be made therein within the scope of the appended claims without departing from the spirit oi. my invention.
What I claim as my invention is:
1. In a plow the combination with the plow beam and the plow downwardly exaXle bar, wheels on the same, of a ring pivoted to the beam and connected to the axle bar, means for revolving the ring and means for connecting the beam to the axle bar with freedom of vertical movement as and for the purpose specified.
2. In a plow the combinatimi with the plow beam and plow downwardly extending from the rear end 01 the same, the axle bar and wheels thereon of a ring pivoted to the beam and connected to the axle bar, ilneans for tilting the ring, vertical extending standards secured to the axle bar and extending through a hole in the beam as and for the purpose speei lied.
3. In a plow, the combination with the plow beam and the plow, the axle bar and the wheels thereon, of an adjustable eonnee tion between the plow beam and the axle bar, a lever pivoted to the rear 01 the plow beam, and means operated by the tilting ol l the lever for raising and lowering the plow beam with relerenee to the axle bar, as and I for the purpose specified. tending from the rear end of the same, the
