Application September 30, 1932, Serial No. 635,531

6 Claims. (Cl. 189 92) This invention has reference to earth anchors for guy-wires and the like and is especially directed to improvements in that class of earth anchors comprising a base plate and slidably arranged flukes superimposed over said plate for movement laterally and radially of the plate and each other, which when located in the ground will rmly and effectually maintain its position in the ground for the uses intended.

1 The invention has for a further object to improve the construction of the base plate, including the nukes and to provide novel guiding means in said plate and flukes whereby to facilitate the operation of said ilukes in relation to said plate and maintain the iiukes in horizontal and lateral alignment with respect to said plate when actuated.

A further object of the invention is to provide new and novel sockets in the flukes, including the slidable spider collar whereby rods having complementary connecting elements may have a jointed connection between the sockets of said flukes and said collar whereby the iiukes, collar and rods may be quickly and easily assembled and disassembled and provide equal and easy 5 base plate and preferably located in underlying relation to the movement of said nukes to provide the base plate with sufcient strength and reinforcement in usage.

The invention has for a further object to provide one or more of said strengthening ribs on the underneath side of said base plate with a fillet of metal, preferably of the same material of the base plate, whereby to compensate for any loss of shrinkage that might occur during the casting of the base plate to insure such plate being of equal strength throughout its entirety, thus avoiding possible cracking or breaking of such plate in use.

A still further object of the invention is in the provision of aligned holes or openings through the base plate and flukes whereby when the nukes are in inoperative or nested position, such assembly may be locked against dislodgment for shipping purposes and the like.

, Other and further objects will more fully appear from the following description.

That the invention may be more fully understood, reference is had to the accompanying drawings illustrating a preferred embodiment of the invention, in which:

Fig. l is a sectional View through the ground in which my improved ground anchor is positioned and illustrating a supporting post with guy-wire, broken away, attached to my improved anchor;

Fig. 14 is a partially sectional perspective view of a modified nut socket construction other than shown in Figs. 2 and`3, and

Fig. 15 is a view similar to Fig. 14 illustrating a still further modified form of socket construction other than shown in Figs. 2, 3 and 14.

Like characters of reference denote corresponding parts throughout the figures.

Reference now being had to the drawings, 1 designates a base plate shown to be disk-like in shape having centrally and axially disposed thereof an upstanding centrally apertured post or sleeve 2 and arranged near the boundary of said plate stepped fluke supports 3 and 4.

Disposed beneath said plate and preferably integral therewith and arranged centrally thereof is a nut embracing inclosure or socket 5 coinprising preferably solid side walls 6, 7 andfS andl a recess opening 9 and the bottom Wall 10, said wall 10 being preferably apertured as at 11 for the clearance of the depending threaded end 12-ofa guy-rod or post 13, upon which threaded end is adapted to be screwed a nut 14 which is initially located within said inclosure by passage through said side recess opening 9, the side Walls 6, 7 and 8 and bottom wall 10 embracing said nut against possible rotation or displacement and further, protection against undue weather or ground contact whereby the nut and threaded end vof said guy-rod or post is materially guarded against weather corrosion.

15, 16 and 17, best seen in Fig. 3, designate ukes or anchor plates adapted to be arranged on the upper' side of said base plate 1 in superimposed relation and to be extended and retracted radially and laterallyof said base plate and each other,.the outer body portions of each of said ukes being preferably fan-like in formation and having a pair of spaced elongated extensions 15a-15a, 16a-16a and 17a-172i, providing a slot therebetween terminating in the body of said fan-like portion. At the end of each slot in the Abody portion of each fluke thereY is provided a tongue extension 15b, 16b and 17u adapted to project from the body of said fan-like portion to a predeterminate point in the length of said slot and preferably in the plane of the body of said fluke, the inner projecting ends of said extensions being preferably arcuately shaped as at 15, 16c and 17c whereby when the flukes are in retracted inoperative and nested positions, as shown in Figs. 2 and 7, said arcuate portions 15, 16c and 17c of said tongue extensions will partially embrace the sleeve or post 2. Referring to Fig. 8, one or more of said flukes are shown having their spaced extensions having preferably curved Enger-like ends or abutments 18 adapted for engagement with the sleeve or post 2 when said flukes are in their extended or projected and operative position which function to limit such projected movements of said flukes when -caused to be extended radially of said base plate 1.

Extending upwardly and preferably integrally from the upper surface of said base plate 1, are a series of spaced sets of fluke guiding pins or members 19, 20 and2l disposed intermediate the edge of vsaid base plate and the vertical axis thereof, said pins adapted to have guiding engagement their outward movement from retracted or nested positions, whereby said flukes when operated under working conditions will enter the ground without deviation in such radial and lateral movements of said base plate.

On the underneath side of said base plate l, I have elected to provide strengthening and reinforcing ribs 22 preferably integral with said base plate and located in spaced relation thereon in underlying relation to the radial and lateral movements of said ilukes on the upper side of Said plate, said ribs preferably connecting and centralizing with said socket 5 and extending radially thereof to the boundary of said plate, whereby to strengthen and reinforce those portions of the base plate subject to the stress and travel of the ilukes thereon. One of these strengthening ribs is provided with a fillet of metal 22', see Figure 4, preferably of the same material of the base plate, whereby to compensate for any loss of shrinkage that might occur during the casting of the base plate to insure such plate being of'equal strength throughout its entirety, thus avoiding possible cracking or breaking of such plate in use.

Located adjacent the outer edge of each fluke and preferably in spaced relation to the tongue extensions, is provided an upstanding boss 23 having a recessed socket 24 opening out of its upper and inner side faces, see Fig. 9, the interior of said socket being preferably spherical in shape, see Figs. 2 and 3, whereby to provide a swivellike connection with an end of a connecting rod to be described.

25 designates a collar being apertured centrally thereof at 26 adapted for slidable relation with the guy-rod or post 13 when in assembled relation as shown in Figs. 2 and 3, the lower face of said collar provided with a series of recessed sockets 27 constructed in a manner similar to the sockets 24 on the flukes. The sockets 24 and 27 are connected by means of .operating rods 28, each of which is provided at each of its opposite ends with substantially elongated cam-like lugs 29 and 30, the longitudinal axes of which are divergent to a line extending longitudinally and medially of the length of said rods, see Fig. 6. In assembly of the connecting rods 28 with the sockets of the dukes and collar, the lugs 29 of the rod 28 are slipped down in the recessed socket 24 of the boss 23 requiring that the rod 28 be held in substantially a vertical position in order that the lugs 29 will enter and be received in said recess whereupon the rod is inclined to the position substantially as shown in Fig. 2, in which inclined position the collar 25 may be lowered, permitting the lugs 30 of said rod to enter the recessed opening 27 within said collar. In order to prevent the dislodgment of said lugs 30-from the recesses 27 of the collar, I have elected to provide a locking means, such for instance, as peening the opening edge of said recessed openings 27 as at 31, see Fig. 2. A locking means is not required for the lugs 29 in the socket 24 since after the lugs 30 are received and locked within the recesses 27, the lugs 29 have been canted or swiveled sufficiently to prevent their removal and can only be dislodged by first removing the lugs 30 from the recesses of the collar and the assembling operation being reversed, as will be understood. Reinforcing ribs 32 are provided preferably in the length of said rods 28 to give them added strength and reinforcement.

In assembled relation, as illustrated in Fig. 2, showing my improved anchor in inoperative and nested position, the flukes are disposed in superimposed rela-tion over the base plate 1, the flukes 15 and 16 having their outer body end portions supported by the flukevsupports 3 and 4, respectively. The fluke 17 being the lower fluke requires no support since it has a supporting and sliding relation when foperated with the upper surface of the base plate l. As shown in Figs. 3 and 8, the fluke supports 3 and 4 function to maintain the nukes 15 and 16 in horizontal alignment in their outward extended movements whereby to facilitate their entrance into the ground.

'In the operation of niy improved anchor, a hole is dug in the ground'of a diameter slightly in excess of the diameter of the base plate 1, whereupon the completely assembled device is introduced into said hole with the parts thereof in the position shown in Fig. 2.

In order to extend or expand the flukes into anchoring position, a tamping instrument is employed against the upper face of the collar 25 and by reason of the connection between the collar and flukes, each iiuke is extended radially and laterally outwardly and forced in the earth surrounding the hole until the downward movement of the collar 25 is limited by contact with the upstanding sleeve or post 2, as seen in Fig. 3, whereupon the hole above the device is filled in as shown in Fig. 1 and the protruding end of the guy-rod is secured for the purposes intended.

Reference being had to Figs. 14 and 15, there are illustrated therein modified forms of guyrod socket construction. In Fig. 14 the bottom wall 101 is solid as are the solid side walls 6, 7 and 8, as distinguished from the bottom wall 10 illustrated in the preferred form, see Figs. 2, 3 and 4, having the aperture 11 therein. The solid bottom wall 101 provides an imperforate supporting shelf for the nut 14 and -prevents earth and moisture from direct Contact therewith. Fig. 15 illustrates a further modified form of socket construction wherein a nut such as 14 is eliminated by providing the space occupied by the nut 14 in Figs. 2, 3, 4 and 14 with a solid integral core 33 with said side walls 6, 7 and 8, said core being provided with threaded openings of different diameter designated 34 and 35 wherein may be threaded the screw ends of a guy-rod having a large or small diameter, whatever the case may be. As iliustrated in Fig. 15, a guy-rod of large diameter has been screw threaded into the large threaded opening 34.

Reference being had to Figs. 11, 12 and 13, there are illustrated therein a modied form of fluke and collar recesses for the reception and securement of a complementary modified form of ends of a connecting rod. In Fig. 13 the boss 231 is provided with a recessed socket 241 opening out of its upper and inner side face similar to the opening 24 as sho-wn in Fig. 9, except the upper face opening is cut away on opposite sides of said opening as at 36 to provide a channel for the passage into and out of said recess opening of the lug end of a connecting rod of the type shown in Figs. 11 and 12. The lug end of said connecting rod, see Figs. 11 and 12, comprises oppositely disposed wedge-shaped lugs 37 arranged transversely the length of said rod and near the end thereof and preferably integrally therewith, the

end of said rod adjacent said lugs being rounded whereby to conform to the recess opening 241 to facilitate the swivel movement of such parts when K connected.

Referring to the recessed socket 271 illustrated in Figs. 11 and 12 of the modified form of collar 251, said socket and recess is similar to the socket 27 except for being larger whereby to accomodate the entrance and swivel connection of the knoblike end 38 of the connecting rod opposite the lug end 37. In assembly of the parts illustrated in Figs. 11, 12 and 13, the lug end of the rod 281 is connected to its complementary fluke socket by placing the rod in a horizontal position in relation to said iiuke plate, in which position the lug end 37 may be lowered through the openings 36 of the boss 231 and into said recess opening 241 whereupon the rod is elevated to substantially the position shown in Fig. 11, in which position the lug end 37 is prevented from dislodgment with the boss 231 and the rod is ready for attachment by its opposite knob-like end 38 to the recess opening 271 of the collar 251. Such attachment of this modified form of rod to the collar is preferably acconipiished before the guy-rod 13 is inserted through said collar and attached to said base plate whereby the collar may be disposed in thecorrect angular position to receive the knoblike end 33 within the recess 271 and upon the collar being turned to its normal horizontalposition to lock such knob-like end in said recess To disassemble the parts just referred to the operation is reversed, as is believed will be understood.

For purposes of shipping my improved earth anchor in retracted and nested condition and in order to prevent the flukes and connecting rods and collar from being actuated to extend the iiukes, I provide holes 39 arranged in axial alignment in said base plate and fiukes for the reception of a securement means, such for instance as a wire 40 having twisted ends.

Quite frequently in the use of ground anchors of the type herein disclosed, occasion requires their abandonment and disuse and it is to these circumstances that I have improved the securement construction on the lower side of said base plate to which the lower end of the guy-rod is fastened. ment of a ground anchor in the ground, it has been necessary to abandon the entire assembly and cutting off the protruding upper end of the guy-rod above the ground at or near the surface of the ground, thereby making little or no salvage by reason of such abandonment which increases the cost of such maneuvers. With the base plate socket construction herein disclosed and described, I greatly reduce such cost of abandonment by permitting the salvage of the entire guyrod by reason of such improved securing means and additionally making such removal operation an easy one, whereby when the threaded end of the guy-rod is detached from said securement means, said rod may be withdrawn upwardly through the collar and out of the ground to be used again, if desired, with another ground anchor.

While I have shown and described my improved earth anchor as having three iiukes, I do not wish to be understood as limiting myself to the employment of three iiukes only, as it is obvious that the anchor may be constructed with more or less without departing from the spirit of my invention.

What I claim is:

1. In a ground anchor, a base plate having an axially disposed upstanding sleeve and a depending socket arranged centrally of the plate, reinforcing ribs on the under side of the plate connecting the plate and the socket, a series of sets Heretofore in the event of abandon-- of nuke guiding members extending upwardly from the upper surface of the plate disposed. in spaced relation to each other and intermediate the edge of the plate and the axis thereof, one set of members for each nuke, and a plurality of superimposed nukes arranged for radial movement of the plate and in longitudinal alignment with ribs beneath the plate, each nuke having a radially disposed slotted opening therethrough for guiding engagement with a set of said members and said sleeve, each member of each set having a bearing relation with a wall of each opening.
