TURNBUCKLE AND SWIVEL. Figs. 166 and 167 are two views of an ordinary turnbuckle, that by turning the turnbuckle in one direction that the rodswill be drawn toward each other, and if turned in the reversedirection they will separate. The student should draw theseand fig. 16S full size. The method of doing this will be evidentfrom the engraving wilhout other explanation. Fig. 16S represents a section, what is called a swivtl, whichis used for the same purpose as a turnbuckle.
