Abstract
Abstract Apparatus for forming an earth anchor includes a rod having a pointed tip with a tapered shoulder connected at an end of the rod, the tip facilitating the driving of the rod into the earth. Overfitting the rod to bear against the tapered shoulder is a sleeve having pre-defined division lines longitudinally from an end thereof. A driving tube is fitted over the rod within the earth to drive the sleeve into engagement with the shoulder, thereby flaring the ends of the sleeve along the division lines into the earth. Means are provided for securing the shaft during the driving operations to prevent the shaft from being further driven into the earth. Also presented are means for flaring a top portion of the cylinder to further enhance the nonremoval properties of the anchor. Additionally presented are apparatus for forming plural anchor members upon the rod, having either single or top flared portions for effecting its nonremoval properties. Additionally presented is an earth anchor which is capable of resisting tension or compressional forces by virtue of an upwardly extending elongated cylinder attached to the outwardly flared members of the flared sleeve.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
A ground anchor comprising: a rod; a pointed tip at an end of said rod to facilitate driving said rod into the ground; a tapered shoulder on said rod; a sleeve of length substantially less than said rod, locateable on said rod whereby an end of said sleeve engages said shoulder, said sleeve being longitudinally scored along at least two paths from said shoulder engaging end to enable said sleeve to be flared along a portion of its length upon being driven into said shoulder whereby said shoulder is constrained by said flared sleeve from upward movement; and a separate and removable driving tube fitable over said rod for driving said rod into the ground prior to the location of said sleeve on said rod, said driving tube being fitable over said rod again subsequent to the location of said sleeve on said rod to engage said sleeve and transmit a driving force to flare said sleeve.
Claim 2
Dependent Claim
157 words
A ground anchor comprising: a rod; a pointed tip at an end of said rod to facilitate driving said rod into the ground; a tapered shoulder on said rod; a sleeve of length substantially less than said rod, locateable on said rod whereby an end of said sleeve engages said shoulder, said sleeve being longitudinally scored along at least two paths from said shoulder engaging end to enable said sleeve to be flared along a portion of its length upon being driven into said shoulder whereby said shoulder is constrained by said flared sleeve from upward movement; and a separate and removable driving tube fitable over said rod for driving said rod into the ground prior to the location of said sleeve on said rod, said driving tube being fitable over said rod again subsequent to the location of said sleeve on said rod to engage said sleeve and transmit a driving force to flare said sleeve.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 further comprising means for connection to said rod to restrain movement of said rod into the ground upon application of said driving force to said sleeve.
Claim 4
Dependent Claim
80 words
The apparatus of claim 1 further comprising a conical wedge receivable upon said rod above said sleeve, a second sleeve of similar construction to said first mentioned sleeve whereby after said first sleeve has been flared, and said driving tube is removed from said rod, said wedge can be located on said rod, and said driving tube refitted over said tube to engage said second sleeve to transmit a driving force to flare said second sleeve upon said conical wedge.
Claim 5
Dependent Claim
53 words
The apparatus of claim 1 wherein saId sleeve is longitudinally scored along at least two paths at an end opposite said shoulder engaging end, and further comprising a second conical wedge locateable on said rod and driveable by said driving tube into said opposite end to thereby split and flare said opposite end.
Claim 6
Dependent Claim
32 words
The anchor of claim 4 wherein said sleeve comprises a collar therearound to limit the splitting of both ends of said sleeve, and to receive the driving force from said driving tube.
Claim 7
Dependent Claim
202 words
The apparatus of claim 1 wherein said sleeve is longitudinally scored along at least two paths at an end opposite said shoulder engaging end, and further comprising a first wedge presenting upward and downward conical shoulders, receivable upon said rod above said firstmentioned sleeve, a second sleeve of construction similar to said first sleeve and a second conical wedge locateable upon said rod, whereby after said first sleeve has been flared at its shoulder engaging end and said driving tube removed from said rod, said first wedge can be located on said rod above said flared sleeve, said driving tube refitted on said rod, and said first wedge means driven into said opposite end of said first sleeve to split said opposite end; said driving tube can be again removed, said second sleeve located on said rod, and said driving tube refitted on said rod and driven into said second sleeve to split and flare a lower portion of second sleeve on said first wedge; and said driving tube can be again removed, said second wedge located upon said rod, and said driving tube refitted upon said rod driven against said second wedge to flare a top portion of said second sleeve.
Claim 8
Dependent Claim
34 words
The anchor of claim 1 wherein said sleeve comprises a collar therearound to limit the splitting of said shoulder engaging end of said sleeve, and to receive the driving force from said driving tube.
Claim 9
Dependent Claim
150 words
Apparatus for earth attachment for resisting tension and compressional forces comprising, a shaft having a pointed tip to facilitate driving said shaft into the earth, an outstanding tapered shoulder on said shaft adjacent said pointed end, a tube of length longer than said shaft, having preformed division lines along at least a portion of its length from an end thereof, whereby when said end of said tube is driven into said shoulder, said tube is split along at least a portion of said division lines and can be flared into the earth to a distance to enable said shaft to protrude above said tube and above ground level, the upper end of said tube being substantially at ground level, and means on said shaft and means on said tube for receiving anchoring attachment, said means on said shaft resisting tension forces and said means on said tube resisting compression forces.
Claim 10
Dependent Claim
150 words
Apparatus for earth attachment for resisting tension and compressional forces comprising, a shaft having a pointed tip to facilitate driving said shaft into the earth, an outstanding tapered shoulder on said shaft adjacent said pointed end, a tube of length longer than said shaft, having preformed division lines along at least a portion of its length from an end thereof, whereby when said end of said tube is driven into said shoulder, said tube is split along at least a portion of said division lines and can be flared into the earth to a distance to enable said shaft to protrude above said tube and above ground level, the upper end of said tube being substantially at ground level, and means on said shaft and means on said tube for receiving anchoring attachment, said means on said shaft resisting tension forces and said means on said tube resisting compression forces.
Claim 11
Dependent Claim
23 words
The apparatus of claim 8 further comprising a collar surrounding said tube to limit the splitting of said tube along said division lines.
Claim 12
Dependent Claim
120 words
An earth anchor, comprising: a rod, including means for receiving anchor connection, a tip connected to an end of said rod having a shoulder extending outwardly from said connection, and a pointed end away from said connection to facilitate driving said rod into the earth, a sleeve of length substantially less than said rod located adjacent said tip, having a plurality of portions split and outwardly flared by said shoulder to engage the earth, said sleeve engaging said shoulder upon movement of said rod to limit upward movement of said rod, said sleeve further comprising an upwardly extending split portion, said upwardly extending split portion being outwardly flared to engage the earth to also resist upward motion of said rod.
