Description
UNITED STATES PATENT QFFICE.o
GEORGE B. SMITH, OF SHOPIERE, WISCONSIN.
I IMPROVEMENT IN STUBBLE-TURNERS FOR PLOWS.
To all 'whom it may concern:
Be it known that I, GEORGE B. SMITH, of Shopiere, in the county of Rock and State of Wisconsin, have invented a new and Improved Plow Attachment for Turning under Stubble, Cornstalks, Svc.; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.
This invention relates to that class of plows which is provided with a rod or bar for turning under the stubble; and consists in the specific construction of the parts by means of which the rod or bar is firmly united to the beam in a simple and economical way.
In the drawing, Figure l represents a perspective view of a plow having my invention applied thereto; and Fig. 2, a front View of the same with the plow-beam in section.
To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and mode of operation.
A represents a bar or rod, of suitable length and thickness, one end of which is attached to the beam of the plow, as shown. It is then curved from the point of its connection with the plow-beam out over the share down to a point nearly in line with the lower edge of the share. Its extreme outer edge is attened and bent slightly back, as shown. The Xed end of the bar is attached to the beam, as follows: The inner end of the bar is bent to form an elbow, the corners of which correspond in length with the depth and width of the plow-beam. A strap, corresponding in length with the horizontal arm of the elbow, is then placed upon its vertical arm, and the two-that is, the strap and horizontal arm of the elbow-are united by a bolt upon the outside of the beam. By this means a rigid connection is made in an exceedingly simple manner.
The operation is as follows: The plow is used in the ordinary manner. As it passes through the ground, however, the bar A draws the stubble, cornstalks, Snc., into the line, and holds them beneath the folding rod or rail, by which means they are completely covered.
As the free end of the bar is ilattened and bent backward it is adapted to cut through earth that may be in its way, and it is also capable of passing any obstruction with which it may come in contact.
I am aware that astubble-turner which operates like mine is old; therefore, I do not claim it, broadly; but my particular construction of shank, and my manner of attaching the salne to the beam, is, I think, new, and possesses many advantages over the old method of securing' co1- ters and similar implements by means of a clevis.
Thus it will be readily seen that if the nut c should be loosened or even lost entirely the bar A cannot become detached from the beam, even though the free end of strap b should drop off from the end of bolt; whereas, with the ordinary clevis attachment, if the nuts become merely loose the bar A or colter is liable to drop out, and does sometimes do so, and get covered up in the furrow, being held only by friction.
Another advantage growing out of my particular construction is this: Neither the strap b nor the shank of the bar has a screw-thread upon it, the thread being only on the straight bolt c,- hence, if the thread is stripped or from any cause becomes impaired, the farmer can readily supply its place, as almost any bolt can be made to answer the purpose temporarily, (a bolt which is unich too long can be fitted by the use of washers whereas, ifa clevis is in use and is injured, the entire device is rendered worthless until a visit to the blacksmithshop can be made, which often consumes time enough to pay for my entire improvement.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In the herein-described stubble-turner A, the angular shank a a', in combination with the strap b and bolt c, the angular shank, together with the strap and bolt, forming the locking device whereby the bar is secured to the plow-beam.
This specification signed and witnessed this 2d day of May, 1871.
