GUY ANCHOR.

Application filed March 22, 1923. Serial No. 626,754.

My invention. relates to expansible sectional anchors connectedto guy wires for anchoring poles smoke stacks, derricks or other objects.

The objects of my invention are to provide highly efficient fastening means for guy wires; to provide an anchor which will withstand a very high strain and at the same time one that can be installed in a comparatively small opening in the earth; to provide an anchor ofeconomical construction and of comparatively small size which maintains its anchoring position without theuse of stones or other similar objects placed thereon; and to provide an anchor which will not creep upwardly through the soft earth due to the effects of water coming from heavy rains" percolating down through the earth above the anchor by providing a large draining Well underneath the anchor and apertures in the anchor through which this water can enter this drainage well; to provide an anchor of sectional construction adapted to enter the hole 7 broken away;

in compact for-1n and permit the sections to spread and embed themselves in the solid walls of the hole when subjected to upward pressure from the guy wires, the entire pull of the anchor being brought to bear against the sides of the hole whichare solid undisturbed earth. p

My invention consists in the construction, combination andarrangement of parts as herein setforth and claimed.

In the embodiment of my invention as illustrated and which shows a preferred construction I provide an anchor 1 comprising a shell formed of a plurality of expansible holding sections2, 3 and 1,- each section pref-- erably having vertical side walls which taper inwardly at their upper ends and each section being preferably transversely corrugated on its surface to form alternate'holding ridges and furrows. Each holding section is provided on its innerside with spaced apart strengthening and holding ribs 5 and 6 havingbearings 7. The upper end of each holding section is'flared' outwardly to form a holding flange 8. A hollow coupling 9 having ears 10 provided with bearings 11 is pivotally connected to the expansible sections by links12. Said coupling is preferably provided with an angular recess 13 on its lower side to partly receive and hold from turning therein nut 14: on anchor rod 15 for the: purpose of salvaging said anchor rodwhen it is desired to discontinue the use of anchor'l. "Spacing sleeve 16 is preferably mounted on anchor rod 15 between coupling 9 and the upper end of anchor 1 and is provided on its upper end with a projecting flange 17 its upper end forming a truncated; cone. Said spacing sleeve serves to limit the upward movement of the coupling and inner ends of the links when the anchor has reached its limit of expansion, thereby preventing the anchor from collapsing.

The anchor is assembled ready for shipment by pivotally connecting links 12 to sections 2; 3 and 4, then spreading the lower ends of said sections and bringing the flanged ends thereof together and placing pivotally connecting links 12 to coupling 9. The anchor is then brought to the contracted position shown in Figs. 1 and 5 and breakable wire 19 is secured around the sections preferable in the groove or furrow shown. The spacing sleeve 16 may then be suitably wired within the parts thus assembled when it is ready for shipment. To install in anchoring position bore a hole 25 such as illustrated in Fig. 9, insert anchor rod 15 through the top of anchor 1, through spacing sleeve 16, through hollow coupling 9 and nut'l lseated in recess 13, place the anchor in hole 25 to the position shown in Fig. 9, then tamp the earth 20 in above anchor 1, then apply upward tension on the rod whereupon the holding sections 2, 3 and 4 will spread outwardly against the side wall 21 of hole 25, thereby securely wedging itself into holding position as shown in Figs. 10 and 14. The guy wire 22 is connected to eye 23 of anchor rod 15 and is suitably connected to pole 24 or other object which it is desired to anchor.

By the expansion feature I secure the advantage of large anchor although it can be installed in a comparatively small hole.

The expansion of the anchor is in direct proportion to the amount of strain placed on the guy wire and will continue to expand until this strain is equalized bv the outside pressure of the earth. The anchor will hold its position securely without the use of stones or other equivalent material placed over or around it and further will hold its position even though the hole is refilled carelesslv without tampinrr. Under certain soil conditions it is practically impossible to dig a hole with an ordinary post hole digger and keep the holeto proper size. as for instance, when boring a hole in gravel by the time the hole is six or seven feet deep it will probably be eighteen to twenty-four inches in diameter on account of the sand and gravel caving in. By placing this anchor .in a hole much larger 'in diameter than the anchor itself this diificulty can be overcome by thor oughly tamping the earth around the an chor and still have the full surface of the anchor and. the holdingarea of the anchor increases by the upward pull it will be held in place on account of the large ma s of earth directly above it. In this anchor all the strain which is applied to the guy wire is transmitted through the mechanism ot the anchor directly against the sides of the hole, thereby wedging any filled or loose earth between the anchor and. the walls of the hole.

It will be understood. that my invention is capable of considerable modification without departure from the scope or spirit thereof as d-efinedin the claims, as for instance, the sectional shell may have a. plain smooth surface or it may be tapered from bottom to top, as desired.
