JAMES EDWARD GAR'VIN, OF ALBANY, NEW YORK.
Specification of Letters Patent.
Patented Dec. d, 1917..
Application filed February 17, 1916. Serial No. 78,888.
To all whom t may concern.'
Be it known that I, JAMES E. GARVIN, a citizen of the United States, and a resident of Albany, in the county of Albany and State of New York, have invented a new and improved Anchor, `of which the following is a full,clear, and exact description.
My invention relates `to means for` anchoring the guy rods of telephone poles or the like, and it has for an object to provide an anchor that may be employed as a substitute for the wood and metal anchors now generally used.
A further object of the invention is to` provide an anchor that may be formed of burned clay and be given a design that will afford a large working surface or area in contact with the sides of the anchor hole and still keepwell within the cost of other forms of anchors.
Another object of the invention is t0 provide an anchor eleinentthat may be utilized for the effective anchoring of a rod where the hole in the earth is cylindrical or where the nature of the soil requires the making of an irregular hole to receive the anchor means. Y
The invention also has for an object to provide an anchor of a character whereby to eli'ect the anchoring of a rod with convenience and despatch and at a cost below that incident to the use of wood or metal anchors.
The invention will be particularly explained in the specific description following.
Reference is to be had to the accompanying drawings forming part of this specificay tion in which similar reference characters indicate corresponding parts in all the views.
Figure 1 1s a perspective view of an anchoring element formed in accordance with my invention;
Fig. 2 is a side elevation of the said element in use on a rod;
Fig. 3 is a view similar to Fig. 2v showing the employment of two of the elements shown in Fig. 1;
Fig. l is a view similar to Fig. 3 showing another manner of employing` two of the anchoring elements;
Fig. 5 is a View similar to Figs. 2 to 4, but showing a modified form of the anchoring element. v
AIn carrying outmy invention 1n the form shown in Figs. 1 and 2,1 produce an anchoring element 10, in the form of a plug adapted to be inserted in a hole in the ground. ln the preferred forni this element is formed of earthenware, that is, burned clay, which may advantageously he vitrilied, or` hard burned terra-cotta.
The element 10 is cut away at one side to present a lateral plane orsurface oblique to the axis of the plug. ThebaselQ of the element 10 is cylindrical and the oblique plane 11 extends from the outer end 13 to the base 12, that is to say, short of the inner end of the plug.
Also, it is to be observed the said plane presents for its major portion a broad lat surface extending continuously and unbroken from side to side of the anchoring element to afford au ample wedging surface. The cylindrical base serves to center the plug in the hole and with the relatively large area at the opposite side bearing against the wall of the hole, the individual element resists a tendency to be tilted.
A longitudinal through-bore 14.i is produced in the plug at one side of the center, that is to say, adjacent to one side of the plug, and thus eccentrically positioned for receiving a rod A to be anchored, said rod being of known form and adapted to receive a nut B on the end thereof after the placing of an element, or elements, 10, as hereinafter explained. The upper terminal of the oblique face 11 is preferably inward from the adjacent side of the plug so that the bore 14rextends through the flat outer end 13. In the preferred form, the plug 10 has a longitudinal groove 15 extending through the cylindrical base 12 from the lower end of the plug to the lower end of the oblique plane 1l and the through-bore 14 is at the opposite side, that is, diametrically in line transversely with the said groove l5. The eccentric position of the rod A develops in the latter the maximum resistance when subjected to strain.
\ In installing the element 10, the same may be used singly as in Fig. 2. As usual an oblique hole is formed in the ground and the said element is passed on to the rod A and held thereon by the nut B. The space formed between the oblique plane 11 and the opposite side wall of the hole may be lilled with broken stone as indicated at 16, Fig. 2, and the stone firmly tamped into place. This way of employing the invention is particularly adapted for anchoring the rod in holes where the soil does not permit of the hole being bored with an earth auger but necessitates the forming of a hole with irregular walls.
It is to be observed that the lateral surface of the plug other. than that of the oblique plane 11, forms part of the saine cylindrical surface with the base .vhereby a broad contact surface is presented to the walls of the liole,- and this formation, employed with the tan'iping of the broken stonek into the space between the oblique surface and the opposed wall' of the hole, serves toA iir-inly hold the anchorin position.
Fig. 3 illustrates the use of two of the elements 10 when a regular hole can be bored with an earth auger. In employing the two anchoring elements as in Fig. 3,'the one element is secured the saine as shown in Fig. Q, and inserted in the hole to the bottom. A second element is then placed in position on the rod A, the latter being received in the longitudinal groove 15, whereby the 'said second element will ride on the rod,r the groove 15 serving to guide the said element to position and aiford clearance for the movement of the element in taking a seat on the firstv element with the opposed oblique planes 11 in contact. The hole is then back filled with earth'as indicated atI In Fig. ll, stilljanothermanner of employing the two elements 10 is shown. In this figure it will-be 'seen that two of the elements 10arc employed in corresponding positions instead'-ofbeing.reversed as in Iig. 3. In installing, the anchor the two elements are slipped onto the rod A and said rod inserted in the hole, the lower element 10 being loweredtoy the bottom ofthe hole and a filling 16b` of stone tamped in position, While the second-element will'be swung aroundon the rod and maintained'at the top of the ground until the first elenientpis tainped-in. The second element is then placed in position and a second stone filling 16b then applied.
Inl? ig. 5a modified form of'plug 1'0a is shown, which has a cylindrical base IMaand a longitudinal bore 14a extending axially in the, said plug to receive the anchor rodA. With this form of plug, oblique faces 11 are formed at opposite sides of the axial bore 14a, said oblique surfaces advantageously being somewhat curved. Desirably` the outer end la'ofrthe,plug'V 102L is fiat at the center between the oblique faces 11, that to say, ythe 'said oblique faces at their upperlendsdo n0t;cut into the bore 14a. With this form of the invention, broken stone 16c is tamped in the hole above the plug and in the spaces `between the oblique faces llaand tliewalls of the, hole.
In all forms the anchoring element, it Willbe observed, constitutes-a wedge coact-` and forming part ofthe same cylindricalsurface with the said base, the saidl plug furthermore, at-a side thereof, presenting a plane oblique to the `axis-ofthe plug.
Q. A rod aiichoringelement in theforin of an elongatedL plug having a longitudinal 85 adapted to be inserted in a holeV4 in the bore for receiving a rod to be anchored, and

surface extending to tleupper Aend thereof and forming part of'the saine cylindricalV surfacewith the said base, the saidV plug furthermore, at aside thereof; presenting-aplane oblique to the axisof the plug; said oblique plane extendingfrom the upper end of the plug and terminatingshortoflower end.
3. A rod anchoring'element Vin theA forni of a plug adapted to be inserted-ina hole in` the the ground, a side of saidelement-beingcutV Y away presenting anobli ue plane at' one side" extending *from the cylindrical base to the upper end, there being a longitudinal through-bore in saideleinent atone'side of the center, between the said' oblique plane and the opposite side-surface, saidoppositeside surface and the said'baseforiningrpart` of the same cylindrical surface, andthgere being a longitudinalslot in the base extending from the lower end ``tosaidobliopie pla-ne and diainetrically in line with the saidbore;
4; A rod` anchoring elementl in the' form of an elongated plug having a ,longitudinali bore for receiving a rod'tobe anchored, and-'1 adapted to be inserted in ahole in the ground, the base of the said lplug-being cylindrical, and :said plu-g presen-ting aside surface extending to the upperendth'ereoff` and forming part of the saine cylindrical surface with the saidbase, the said plugfurthermore, at aside thereof, presenting a plane oblique to the axis ofth'e plug, said oblique plane extending from the upper ely-idl of the plugand terminating shortl offthe lower end, there being a longitudinal-slot in the base extending from said' oblique plane to the lower end of the plug.`
5. A rod anchoring device in the form of a wedge, and having a longitudinal throughborei to receive, a rod to beancliored; said bore ranging `substantially parallel with `the axis of the wedge adjacent to one side thereof between said side and the center so that the anchored rod will cause the anchoring element to bear with increased pressure against the opposed wall of the hole in which the rod is to be anchored.
6. A rod anchoring device including a plug adapted to enter the hole in which the rod is to be anchored, and having means to receive the rod, said plug having a wedge formation at the upper portion and a nonwedging base portion below the wedge formation, presenting an external surface at all sides parallel with the axis of the plug, the said Wedge portion and the said base portion being co-terminous a distance above the bottom surface of the plug.
7. A rod anchoring element having a passage therethrough to slidably receive the rod to be anchored, said element being cut away at one side presenting a plane inclined to the axis of the element, said plane extending from the upper end and terminating short of the base end, and said element presenting'a lateral surface at the opposite side substantially parallel with the axis.
