Application filed January 8, 1921.*I Serial No. 435,868.

To (/,ZZ @07mm z' may concern.'

Be it known that I, LIONEL ALFRED BEN- Nn'r'r HU'r'roN, a subject of the King of Great Britain, a resident of the city of Calgary, Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in Reenforced Anchors Made of Plastic and Semiplastic Material, of which the following is a specification.

This invention relates to improvements in reenforced anchors made of plastic and semplastic material, and the objects of the invention are to provide an anchor which will wedge against the material around it, to offer great resistance that is not liable to be easily overcome, to render the construction simple and not liable to go out of repair, and generally to adapt the same to better perform the functions required of it.

With the above and other objects in view, the invention consists essentially of the improved construction particularly described in the following specification and drawings forming part of the same.

In the drawings:

Figure 1 is a side elevation of the anchor and rod as seen inserted in the earth.

Figure 2 is a longitudinal section of the wedge shaped anchor of the same.

Figure 3 is a cross section on the line 3-3 of Figure 2.

Figure 4 is a longitudinal section of a modified form of anchor.

Figure 5 is a longitudinal section of a further modified form of anchor.

Like characters of reference indicate corresponding parts in all the figures.

Referring to the drawings; A represents an anchor consisting of a conical part 10 and a depending cylindrical portion 11 which is adapted to withstand the strain exerted against it. The anchor can be made of concrete or burned clay or other plastic material.

The anchor is provided in its central part with a hole 13 bored therethrough and having a sleeve 14 of sheet metal inserted therein.

A cross-shaped reinforcing member 16 is provided which is designed to be embedded in the'concrete casing 10 as approximately the bottom thereof. The reinforcing member 16 has arms 12, the ends of which are turned upwardlyv as at 17 so that the member 16 as a whole is solidly anchored within the concrete anchor 10.

A rod 15 extends within the sleeve and through the reinforcing member 16 bored for that purpose. rThe rod 15 which is screw threaded at its lower extremity is retained with the member 16 by means of a nut 18 threaded on the threaded portion of the rod, anda recess 19 in the bottom surface of the cylindrical portion 11 of the anchor affords room for the nut 18.

The rod 15 is terminated at its upper extremity with an eyelet 20 designed to recelve a wire holding the post that is to be anchored or supported.

When in use the anchor is placed in the hole bored in the earth and after the rod 15 has been connected to the anchor 10, a few shovelfuls of gravel or crushed rock are u thrown in on top of it and the hole is then filled with earth.

Figu're 4 illustrates a modification of the invention in which the anchor 10a is cast in a sheet iron mould 21, which mould is designed to remain thereon permanently and form part of the anchor. The anchor can b e 1cast of any plastic or semi-plastic materia The anchor is bored at 15a and has a sleeve 14a of sheet metal inserted in the hole thus provided. The rod 15 extends within the sleeve 14a and through the mould 21 bored therefor. The rod is fastened to the anchor by means of the nut 18 threaded to the lower portion of the rod.

A washer 22 is provided on the rods 15, between the nut 18 and the bottoms for the sheet iron mould.

Figure 5 shows another or simpler form of anchor in which the concrete anchor 10 is simply bored at 13 to receive the sleeve 14C adapted to engage the lower portion of the rod 15. A washer 22 is provided at the bottom surface of the anchor and a nut 18 is screwed on the threaded lower portion of the rod to retain the same to the anchor.

As the tension is exerted on the rod by the straightened post, the gravel is forced into the indisturbed earth by the wedge shaped anchor, thus offering great resistance.

As many changes could be made in the above construction and many widely different embodiments of my invention within the formed with a. depending cylindrical bese' end having' a hole bored dierethrough` e sleeve of sheet metal in the hole, i reinforcii g' member embedded Ain the `b21-see a recess termed in the Vbottom surface of the bese, e rod eXtending,v Within the sleeve through the reinforcing member, the rod beingscrevv threaded it its lower end and e, nut located. 7

in the recess formed in the bottom of the bese and retaining the rod to the reinforcing member'. l

2. in anchor comprisinge conical portion and a dependingI cylindrical base helving a Mesem hole therethrough, a sheet metal sleeve in 4'the hole7 e rod 'formed with en eyelet and extending Within the sleeve, e. cross-shaped member secured to the enchon and inea-ns securing the rod to the anchor and engaging the cross-shaped member.

3. A concrete anchor comprising e concrete block having a conical upper portion and e cylindrical lower portion, e crosssheped member formed with upturned outer ends embedded inthe cylindrical portion, end e rod passing through the block secured thereto at the lower end `end having an eyelet at the upper end.
