PLOW.
SPECIFICATION forming part of Letters Patent No. 443,861, dated December 30,1890.
Application filed July l2, 1890.
To a/ZZ whom t may concern.-
Be it known that I, CYRUS MARSH, of Wash- 1ngton, in the county of Adams and State of Mississippi, have invented certain new and useful Improvements in lPlows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawing, whiclrforms part of this specification.
My invention relates to an improvement in plows; and it consists in the combination of a plow of any suitable construction, an arm or standard which is secured at its upper end to the rear end of the beam and pivoted at its lower end as near to the bottom of the plow-bar as is practical, and a bolt which passes through a slot in the arm or standard to further secure it to the plow, as will be more fully described hereinafter.
The object of my invention is to pivot the beam to the plow through the arm or standard, whereby the' plow can be made to run deep or shallow by using the handles as 1evers, whereby the plowman can change the running of his plow instantly from shallow to deep plowing without stopping to adjust any part, and to connect the standard at the bottom of the plow, so that the draft will be at that point instead of at the top.
The accompanying drawing represents a slide elevation of a plow to which my invention 1s applied, the beamand standard being shown in one position in solid lines and in another position in dotted lines.
A represents a plow of any suitable shape, size, form, or description that may be preferred, and to which the handles B are rigidly secured. The standard C, which may be of any desired construction and is set inside of theplow,sothat there willbenofrictionagainst it upon the land side, is rigidly secured at its upper end to the rear end of the beam and is pivoted at its lower end inside of the plow as near the bottom of the plow-bar as is practical. 'Ihrough this standard at any suitable point is made a curved slot D, through which loosely passes a bolt G, which has its ends Serial No. 358,563. (No model.)
secured in any suitable manner to or near the upper edge of the plow, and which bolt plays freely back and forth in the slot as the plow is adjusted by means of the handles. This bolt-passes through this slot for the purpose of holding the beam of the plow in its proper position and allows the beam to move up and down at its front end, as shown by dotted lines. If so desired, a band can be carried around the arm or standard and used instead of thel holt. By means of the construction here shown the point can be made to run nearly straight into the ground and thus made self-sharpening to a great degree, instead of running at an angle which causes more or less friction,destroys the edge of the plow, and causes bad work to be done, with increased labor on both man and beast. Nearly all of the plows now made enter the ground by suction-t'. e., the cutting-edge is below the plow-bar. This creates friction on the bar, and it soon loses its edge and has to be sharpened. By the construction here shown the plow-point is set on the line with the bar. Consequently the friction across the edge is avoided and is made self-sharpening to a great extent. The handles form the lcverby which the plowman controls his plow independently of the ground or suction of the plow, and hence he can plow shallow or deep at will and save a large percentage in draft and fully double the wear of the plow-point. The importance of this construction will be readily perceived by the plow man. In nearly every field one part of the soil is harder than the other, and hence the plowing with the ordinary plowis never uniform. W'here aslight movement of the handles changes the plowing at the will of the operator the most difficult plowing can be done with accuracy and ease. This leverage of the handles enables the plow to be held easily and steadily at any required depth and enables grasses and weeds, which cannot be plowed to advantage by ordinary plows unless very sharp, to be dug up by the roots with perfect ease.
Having thus described my invention, I claim- In a plow, the combination, with the plow having the handles rigidly connected thereto, In testimony whereof Imix my Signature in of a standard having its lower end curved presence of Twowituesses. forward and pivoted to the lower forward end T Y' 1 i i r S of the plow, ii slot 1n thestandardorplow, and C 3 R1' u Il 5 o bolt which passes through the slot and lim- \\'ituesses:
