The eyes in this stylehave been of cast-iron heretofore, and consequently provedweak. This anchor when used with a rod made of a scrappiece of strand, it is claimed, is as durable as the rod has the added advantage of enabling the builder of pole linesto use up his short pieces of strand, which otherwise would bewaste material. Fig. 4 is an ingenious method of clearly showing the mannerin which the lines of force operate. At first glance those whohave never used Stombaugh guy anchors are apt to considerthe holding power of the device as only so great as if a hole,the diameter of the helix, were dug and the anchor placed in itand the hole filled and tamped. In reality the lines of force are. FIG. 4.—APPLICATION OF GUY ANCHOR Building, St. Louis, will gladly answer any inquiries and givedetailed information. GRINDING ATTACHMENT FOR NEW YANKEE DRILLGRINDERS The accompanying illustration shows a grinding attachmentthe Wilmarth & Morman Company, of Grand Rapids, Mich.,has recently designed for its well-known new Yankee drillgrinders. As will be seen, the arrangement is similar to that used in thenow familiar disc grinders, and consists of a table and its sup-ports, capable of oscillating on a stud, and counterbalanced tokeep it right-side tables are fur-nished—a flat onewith a ridge at oneside to square workup against, and V-shaped table forround and similarwork. These tablesare quickly inter-changeable withoutthe use of a wrenchand are adjustable forangle in all directionsas well as up anddown, and cutters,chasers, punches,dies, gibs, nuts, keysand a multitude ofsmall parts that would otherwise be planed, milled or filed may readily
