Application filed Merch 26, 1915. Serial No. 17,098.

To all 'whom it muy concer/z:

'Ee it'lniown that I, Pnncr J. Hixmtansn,

a citizen ot' the United States, and resi dent of Lincolnnn the county ot Lancaster and State of Nebraska, have invented eervtain new and useful improvements in Post- Anchors, of which the following is a. specification.

My invention relates to anchoringy devices for posts and has particular' reference to a novel two-part anchoring device, each of which 4may be driven to secure theanchor ing action.

It is ywell known that in the use of nietaliic structures for corner or end iosts ot fences, anchors for guy wires for poles or other structures, sonic eiiicient means should be provided for securing the positive roten? tion of the member in the ground. Bitten ent forms ot anchoring,- devices have heen proposed, niany of which are so constructed as to obviate the possibility et merely driving the posts or anchoring members.

An object ot nr, invention is toprovide a very simple, inexpensive and eli'icient anchoring device which may `be positioned hy driving action and requiring' no excavating` or the use of concrete. The invention may take many different i'orrns, but one ot the essentials ot the present device is the employment of a spreader and reinforcing; element which is first driven into the ground, and a cylindrical `metallic member which may he driven over the spreader, the lower end ot the last driven clement heing;r slitted, to the end that when such slitted cud contact-s the tlared end of the previously driven spreader the slitted ends will)i are and iorin an eiiicient anchor. l

The invention will be more readily understood hy reference to the accompanying; drawings, wherein- Figure 1 is an elevation of a' fence post of hiillow c if'lindrical'forrn; the lower end l ot'. which is slitted. i

Fig. Q ,is an elevation o'ta spreader, such as is r'ontenoplated hy me,

Fig. 3 is a view showingr the spreader after having been driven into the 'ground and the post also driven into the ground but just prior to the point of spreading the lower end thereof,

is a section on the line 5%5 ot Fig. 10 is a vie-tv ot' the parts showin in Fig. 9 in completed position.

Referring; particularly to the construction shown in Figs. 1 to 5 inclusive, it will he seen that l provide a.post 10, which may be circular or of other desired cross section,v

the lower end ot the post heling slitted, as at 11, to provide segments 'l2/which act as anchors. The number ot these slits, and therefore ot' the anchoring members, is iinmaterial. tour slits. n order to accentuate the bending action at the proper point, l may provide apertures 13 at the vtermination. of the slits. For use in connection with the post just described, I provide a combined reinforcing element and spreader, which may consist; in the shank portion 'le and the spreader portion, includingn the wings 15. 'lhe shank portion may loe crucitorm in cross he umlerstood that this element to act Preferably, however, l 'purovide as a reinforcement for the lower endof the l tube it should provide a plurality of points of contact with` the interior or' the post. The wings or webs 15, of which l preferahly provide eight, extend radially from thne axisot the shank 14 and terminate in .a driving,Y point 16. The upper edges 17' of the webs 15 are curved or beveled. in such manner as to suitably expand or flare the segments 12 at the lower end of the post. I

l preferably provide a number lot the'welos 15 `which' shall be .in excess ot the nurnlier of segments ot the .post to loel anchored; this to 'obviate the possi-bility of the posts being so located that the-slits 11 therein should each register with a wing 15. In the construction shown in Fig. 5 4the spreader has beenA driven until its top is substantially flush with the surface of the ground. The post 10 is then driven, to the point where the lower end is about to be fiared by the webs 15. In Fig. 4 the driving has been conipleted and 1t will be seen that the segments 12 of the posts have been flared and a positive anchor is secured thereby. Furthermore, :it wi be seen that lthe shank la of the spreader serves to reinforce the lower end of the post and prevent any bending thereof at a point below the'ground. This is an important advantage which should not be overlooked.

In theeonstruction shown in Figs. 6 to inclusive l.finiodified forni has been shown as an anclior'for a guy wire. In that construe tion the anchor 18is iprovided at its upper end with an opening 19, to which the guy wire is secured. In this instance I have provided but two slits 2O in the lower end of the cylinder, the metal in such cases being sufficiently light that the bending or flaring action may take place. In this' construction the spreader is composed of the cruciforin shank 21, and a pair of wings 22 which serve to flare the lower end of the anchor. In this construction both the anchor and the .spreader are driven simultaneously, the

' parts being assembled in the position shown in Fig. 6, the lower end of the cylinder being held against two wings 23 and prevented fromspreading by reason of the lugs 24 on the upper edges thereof. After the assembled parts have been driven, the cylinder is given a quarter turn, or until the slits 2O thereof register with the wings 23. Continucd driving of the anchor member serves to flare the segments thereof. In the case of the construction just described the spreader may have a very short shank; in fact, only l of sufficient length to insure the proper holdsection and have a hole 28 in its upper end to which a wire may be secured. The lower end 29 may be a. duplicate of that described in connection with the construction shown in Figs. l to In the present construction the element 27 is first driven intofthe ground the required distance, after which the tube orv cylinder 25 is located'l thereon and a driving tube 3() abutted thereagainst; the short tube 25 is then driven until the segments at the lower end thereof are flared and a suitable anchor is secured for the attaching elcnient 27 after which the driver is removed,

leaving the parts in the ground in the position shown in Fig. 10.

The flared end of the spreader actsinerely to start the spreading action of the fiukes or segments, their contact with the ground continuing the spreading without a great deal i of assistance from the spreader wings. The

advantageous result secured by the us'iof the present device is secured by reason of the fact ithat the spreader is so constructed as to cause an initial curl to the lower end of the slitted post whereby the flakes are Caused to project or move in a substantially y horizontal line, une points'of the flukes en' tering easily iiito the packed earth. IThis rei sult is not secured where the lower end of the post is merely flared as in that instance 30 the only iiare is secured by compressing the I adjacent earth and the lower end of the post is held solely by friction, and in a manner similar to that of an expansion bolt. In ap plicants construction the `post is held 35 against a vertical pulling action by reason of the fact that the fiukes underlie a large extent of earth and this entire quantity of earth must 'be lifted or the linkes must be bent before the post can be raised. While the spreader has been described as of angular cross section, it will be understood that a tubular forni might be employed with equal facility; also that the shape and proportions of the tube and spreader might be. e5
