ANCHQRING POST Filed June 28, 1933 I i 2% VIII/[11% 11/ 27 Inventor Patented Apr. 17, 1934 UNITED STATES PATENT OFFIQE 2 Claims.

The present invention relates to improvements in anchoring post construction.

An important object of the invention is the provision of an anchoring post constructed so that it may be easily driven into the ground and firmly secured therein.

A further object of the invention is the provision of an anchoring post having a plurality of movable anchoring arms adapted to assume l0 retracted positions when the post is being driven into the ground and to be moved radially outward for fastening the post.

Another object of the invention is the provision of an anchoring post provided with a plurality of radially movable anchoring arms and a ring member which may be actuated to swing the arms outwardly from a retracted to outwardly projecting anchoring positions.

Still another object of the invention is the provision of an anchoring post of the above character which will be relatively simple and durable in construction and which will be firmly secured in the ground.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevational view of the preferred form of the post showing the arrangement of the anchoring arms during initial driving operation,

Figure 2 is a similar view showing the arrangement of the arms when the post is anchored,

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 1,

Figure 4 is a vertical sectional view showing the arms in extended anchoring positions,

Figure 5 is a transverse section taken on the line 55 of Figure 1,

Figure 6 is a side elevational view, partly in section, of a modified form of the post, and

Figure 7 is a vertical sectional View through the same in anchored position.

Referring to Figures 1 to 5 of the drawing, wherein is illustrated a preferred embodiment of the invention, the numeral 10 designates the main body section of the post which is in the form of an elongated cylindrical tube preferably formed of metal or other suitable material. To the upper end of the post body 10 is rigidly secured a cap plate 11.

To the lower end of the post section 10 is secured a bottom tip section, generally indicated at 13, embodying a tapered cone-shaped point 14 and an upwardly projecting shank 15. As shown to advantage at Figures 3 and 4 the upper enlarged part of the tip 14 is of greater diameter than the circular shank 15 and the tubular body section 10, the lower end of the tubular section being adapted to be tightly fitted over the shank. The body 10 and the tip section 13 are rigidly connected by means of a rivet 16 driven through the lower portion of the body section and the shank 15.

The shank 15 and the upper enlarged part of the tip 14 are grooved to accommodate a plurality of anchor arms 18. With this in mind, a plurality of longitudinally extending grooves 19 are formed in the shank in registration with radial grooves 20 formed in the upper enlarged part of the point. Each of the anchor arms 18 is formed to provide approximately U-shaped hook elements 21 at the lower ends. The outer end portion of each arm 18 is also bent outwardly to form a ground engaging fluke 22.

About the exterior of the post body section 10 is slidably fitted an annular ring 24 having the outer edge bevelled so that the ring has a diminishing taper toward the lower edge.

When the post is being driven into the ground the arms 18 are, through the medium of the U- shaped hook elements 21, held in longitudinally extending positions against the lower part of the body section 10, as shown to advantage at Figures 1 and 3, the ring 24 resting on the upper extremities of the arms. When the post has been driven to a predetermined depth, the ring 24 is forced downwardly by means of a rod or other suitable implement causing the arms 18 to spread outwardly from the body. Any attempt to pull the post upwardly will cause a further spreading movement of the arms, as shown at Figures 2 and 4, to resist such upward movement and securely fasten the post in the ground.

In the modified form of the post shown at Figures 6 and 7, the body section indicated at 26 and the tip section generally indicated at 27 are formed similar to the corresponding sections of the preferred form of the post. In this case, however, the anchoring arms. indicated at 28, are formed with relatively long overlapping interior sections 29 tightly compressed between the tip shank and the lower part of the body section. The arms 28 are preferably formed of flexible or spring metal and the spreading ring 30 rests on outturned upper portions 31 thereof during the introduction of the post.

llil

When the post is in proper position the bevelled spreading ring 30 is forced downwardly to spread the outer sections or arms 28 of the anchoring members, as shown at Figure '7.

It is to be understood that the forms of my invention herein shown and described are to be taken as preferred examples of the same, and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. An anchoring post comprising a body section having a lower tubular part, a tip section having a tapered point and an upwardly projecting reduced shank, the said shank and upper part of the point being provided with registering grooves, means connecting the lower part of the body with the shank of the tip section, a plurality of anchoring arms having U-shaped bottom elements disposed in the grooves in the shank and secured therein by the lower part of the body, the said arms being adapted to normally extend longitudinally against the lower part of the body, and a ring slidably fitted on the body for spreading the arms to outwardly projecting anchoring positions.

2. An anchoring post comprising a body section having a lower tubular part, a tip section having atapered point and an upwardly projecting reduced shank, the said shank and upper part of the point being provided with registering grooves, means connecting the lower part of the body with the shank of the tip section, a plurality of anchoring arms having U-shaped bottom elements disposed in the grooves in the shank and secured therein by the lower part of the body, the said arms being adapted to normally extend longitudinally against the lower part of the body, and a bevelled ring slidably fitted on the body adapted to spread the arms to outwardly projecting anchoring positions when the ring is forced downwardly on the lower portion of the body.

JOSEPH OCTAVE SAMSON.
