EARTH-ANCHOR.

{5pcclilcatien of letters Batent.

racemes-ma nesia.

a lication cleaner-cue, 191a. serial no, crime.

To all whom it may concern:

Be it known that ii, Jasrnn Moravian, a citizen of the United States, and resident of Kirkwood, St. Louis county, Missouri, have invented certain new and usefpl improvements in Earth-Anchors, or which the following is a specification containing a full,

clear, and exact description, reference being .out in the claims and illustrated by the accompanying drawings, in which- Figure l is a plan of one out my improvd anchors; Fig. 2 is a transverse sectional elevation taken on the line 2-2 of Fig. 1; and Fig. 3 is a view on a reduped scale showing my improved anchor as in use.

Referring by numerals to the accompanying drawings: 5 designates the base or body portion or the anchor which is approxinately disk-shape. Formed on the upper face of the body 5 and preferably can ntegral-therewith is a sleeve 6, and leading radially from the sleeve is a lurality of outwardly and downwardly inc ined ribs 7, the inner margins 0t which connect with and term a part of the sleeve 6, and the lower margins or which connect with the body portion 5. Each of these ribs extends to a point slightly removed from the margin of the body 5. Formed in the top1 face of the body 5 adjacent the margin t erect is an annular channel 8.

9 designates a plurality of ribs which are formed integral with the body 5 between each of the ribs 7. These ribs 9 are of less length than the ribs 7 and at their inner ends extend in planes slightly above the upper margins oi the ribs 7';

l0 designates theugual' anchor rod which portion tbereo forms no part of my invention and which is secured to the anchor by meansof a nut 11;

In practice this anchor is placed in a bore in the earth usually formed at an incline, as shown. The anchor rod having been previously secured to the anchor, the anchor rests in the bottom of the bore and, by reason of the flat'bottomed base or body portion, there is no space left for water to collect and stand, which is objectionable for well known reasons. After being positioned as just described broken stone is placed upon the anchor and tamped, the inclined ribs serving to deflect the, stone and cause it to embed in the earth to increase the holding power of the anchor. After the broken stone has been tamped and embedded in the walls of the bore in the earth and there is an upward strain upon the anchor it is obvious that, by reason of the projecting polnts of the intermediate ribs 9 and the annular channel 8, the anchor will hold to the broken stone which, being a mass having a part embedded in the earth surrounding the anchor, adords maximum of boldmg power.

t 15 to be understood that after the anchor has been set in position the entire opening or here is filled in an ordinary manner.

ll claim:

1. in an anchor of the class described, a base, spaced apart ribs on its upper face whose upper margins incline downwardly and outwardly, and ribs, onthe upper taco of the base intermediate the-first mentioned ribs, whose upper mar'have at least a lying in planes above the upper margins of the first mentioned ribs.

2. In an anchor of the class described, a base, spaced apart ribs on the base whose upper margins incline downwardly and out? wardly, intermediate ribs whose upper margins have at least a" portion thereof i 'ng in planes above the upper margins o the first mentioned ribs, and there being a continuous channel formed in the upper face of the base adjacent the outer ends of said ribs.

3. As a new article of manufacture, an earth anchor, comprising a disk-shaped base, a sleeve formed integral with the base, a plurality of outwardly and downwardly inclined ribs extended from said sleeve to a point; adjacent the margin of the base, a

I plurality of ribs arrangefi between the first In testimony whereof 1 have signefl my mentioned ribs, the said last mentioned ribs name to tins spooificntaon, in prosonco of having at least a portion of their upper .two subscnbmg witnesses.

mnrgins lying in planes above the margins JASPER BLACTUEN, 5 of the first mentioned ribs, and there being Witnesses:
