The Scotch Clevis. or chain is attached ; and thus a level gauge is obtained for the plow at any required depth. The rear of the clevis terminates in a T form, with various holes for the reception of the back bolt. There are three holes in the plow-beam through which the back bolt may pass; and the changes which they aftbrd, together with tho^ obtained by the various holes in the termi- nus of the clevis, give to or take from the plow any amount of land desired. Eleven changes are attainable by the use of this clevis. The means of making them may be readily seen by a reference to Fig. 95. The Half Scotch Clevis, also of malleable iron, is represent- ed by Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Mapes, Charles Victor, 1836-1916.
