ANCHOR APPARATUS Filed March s1. 1960 Wm N .....i......\ll..
INVENTOR JESSE C. THoMPsoN,Jr.
ATTORNEY United States Patent O 3,115,226 ANCHOR APPARATUS Jesse C. Thompson, Sir., Hollins College, Hollins College, Va. Filed Mar. 31, 1960, Ser. No. 18,914 12 Claims. (Cl. 1259-92) The present invention relates to anchor apparatus and has particular reference to an improved ground anchor driver and rod which may be placed in the ground lwithout the preliminary preparation involved in digging a hole in the earth. Q
Means for anchoring wires and supporting the weight of such above ground structures as signs, mail boxes, posts and a variety of other structures, are quite necessary and widely used. D
A simpler and less expensive way of inserting these ground anchors is very desirable when the extensive use that is made of this type of apparatus is considered.
Accordingly, the present invention is directed to an apparatus which may be inserted in the earth without prior digging and the accompanying loosening of the ground which would tend to weaken the holding power of the ground and thus lessen its ability to support an anchoring apparatus.
Basically, the invention provides a novel and improved means of producing a cavity to hold a ground anchor by sinking a hollow steel tube into the ground and thereafter lowering the anchor into place through this hollow tube.
Accordingly, the present invention is directed to the use of a hollow tube utilizing an explosive charge in its base to produce the required cavity for containing the ground anchor against the forces tending to free it from the earth.
Furthermore, this invention discloses several examples of different types of ground anchors that can be used as part of this novel device.
Other objects and advantages inherent in the invention will become apparent from the following description, reference being had to the accompanying drawings, of which:
FiG. 1 shows the driving tube and its component parts used for insertion of a ground anchor in the earth; FIG. 2 shows the driving tube in position after being hammered into the ground;
FIG. 3 shows one type of anchor inserted through the driving tube and ready for use;
FIG. 4 shows a different head for a similar type of anchor;
FG. 5 shows an expandable type of anchor being inserted through the driving tube; and
FlG. 6 shows this same type of anchor in its expanded position in the earth.
Referring first to FIGS. 1 and 2, there is illustrated a hollow driving tube 1t), preferably of steel in order to have a maximum structural strength, with its lower end 11 perforated with many small holes. A driver 12 is a solid piece of steel with lower end 13 shaped to it down into the upper end of hollow tube and a flat end 14 shaped thusly to receive the blows of a hammer or other similar acting device. This allows tube 1l) to be driven into the earth without battering the tube. When tube 1t) has been inserted in the ground to the required depth, driver 12 is then easily removed. A driving point 15 of solid steel has one end 16 with a small enough diameter to enable it to fit into the bottom end of hollow tube 1li and an outer circumferential section 17 with a diameter the same or greater than the outside diameter of tube 1t), thereby enabling the downward force applied to driver 12 to be transmitted along the sides of hollow tube 1t) to 3,115,226 Patented Dec. 24, 1963 ice driving point 15 and thereby facilitate the driving of tube 1@ into the ground.
Anchor rod 2li, shown in FIG. 3, which is one of the types of anchor rods which may be used with this type of driving tube, has a ridged undulated end 21. This type end 21 of anchor rod 20 is found most useful when it is planned to use concrete 23 for additional strength of anchorage in the earth at the base of rod 20. The eye loop 22 on the opposite end of rod 20 may be used for Stringing of wire.
FIG. 4 discloses the top part of an anchor rod 30, similar to the type shown in FIG. 3 except that the upper end 31 of anchor rod 3i) is adapted for attachment of a steel rod or tube. Most other types of anchor rod tops are adaptable for use here although only two examples are shown.
In use, hollow driving tube 10 with driver 12 inserted at its top and driving point 15 inserted at perforated end 11 is driven into the earth. After the required depth is reached, depending upon driver tube and anchor rod length, and the amount of strength of anchorage needed, driver 12 is removed. An explosive charge (not shown) is then lowered down through hollow tube 10 into the perforated end 11. The explosive charge is then detonated and the resulting explosion forces out driving point 15 and creates a large cavity at the base of the driving tube 10. The perforated section 11 either allows for the escape of some of the explosive force and gases through the holes therein, thereby diverting explosive power from the open top and expelling it where it will accomplish the most work, or if made more fragile, section 11 will shatter outward as shown in FIGS. 3, 5, and 6. A mixture of concrete 23 is then poured down through driving tube 1@ into the cavity formed at its base. This concrete mixture 23 is poured and tamped down until it completely lls the cavity. Either anchor rod 29 of FIG. 3 or its modiied form, anchor rod 3d of FIG. 4, is then pushed down through driving tube 10 into the concrete mixture 23 at its base. The concrete mixture 23 is then allowed to set and hold the ridged, undulated end 21 of anchor rod Ztl or anchor rod 30. An anchor wire is then attached to anchor rod eye loop 22 or a metal tube can be attached to end 31 for attachment of some above ground structure, such as a post.
Ait times itis not desirable to fill with concrete 4the cavity formed by the detonati'on of the explosive charge at the base of driver rod 10. ln such cases, an anchor rod with a ldifferent base structure is conveniently used. A type of anchor, such as anchor rod 40 with its upper end formed either as eye loop 22 or end 31 and its `bottoni end, as shown in FGS. 5 and 6, may be used. FIG. 5 shows this modified form of anchor rod 40 in a closed position as it is being inserted through driver tube 10 into the cavity in the earth formed at the base of tube 10. Arms 41, 42, 43 and 44 in FIG. 5 are shown as folded up along the side of anchor rod dll but upon leaving the end of driver tube 1li, and entering the cavity below, a spring action 45 which has been built into the hinged arms 41, 42, 43 and 44 causes these arms to extend outward in a position perpendicular to the long axis of anchor iod 40, as shown in FIG. 6. In this position any force tending to pull the anchor rod 40 back up toward the surface is opposed, thereby providing lirm anchorage without the use of a concrete mixture or any similar substance.
It will thus be aparent that this anchor apparatus can be used more expeditiously than present anchoring equipment now in use with an elimination of the time and expense involved in digging the necessary holes for insertion of anchor rods.
Furthermore, it should be noted that any type of anchor rod capable of passing its ground inserted end through a driver tube may be used in this invention. Nor
is there any size limitation placed on the driver tube, since it may just as well be driven by hand hammers as well as massive pile driving equipment.
It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and, therefore, the invention is not limited to what is shown in the drawings and described in the speciiication, but only as indicated in the appended claims.
