A. A. HOLLOS ANCHOR PosT May 9, 1933.

Patented May 9, 1933 PATENT OFFICEl VAvensis A. Hornos, or TOLEDO, oHIo ANCHOR y ros'r Application filed. July 1, 1931. Serial No. 548,067.

This invention relates to an anchor post, which is adapted to be forced into the ground, and to which a cable may be secured, and an object is to produce a new and improved anchor post having the novel features of construction, arrangement and operation hereinafter described.

An embodiment of the invention is shown by way of illustration in the accompanying drawing, in which:

v Fig. 1 is a longitudinal sectional elevation of the anchor post;

Fig. 2 is an enlarged transverse sectional elevation on the line 2-2 of Fig. 1;

. Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 4;

Fig. 4 is an elevation of the lower end portion of thepost; and

. Fig. 5 is a top plan view of the scoop shaped outer end of the blade members.

The illustratedembodiment of the invention comprises an anchor post having an elongate metallic barrel l0, having a lower pointed end portion 11 suitably secured 1n place. On the outside of the pointed end 11, and extending part way up the barrel 10 is a helical blade 12 to enable the post to be screwed into theV ground.

Formed in the lower end of the barrel 10 adjacent the pointed end 11 is a pair of substantially T-shaped openings 13 through which mayproject a pair of blade members 14. The lower ends of the blade members 14 are engageable with a cam member 15 formed on the pointed end. The cam member 15 has oppositely inclined cam surfaces to cam or force the blade members 14 outwardly through the openings 13 when movement in one direction is imparted thereto.

Each blade member 14 is provided with a scoop or spade-shaped outer end 16. Formed in the inner end of each of the arms 14 is an outwardly extending pointed projection 17, which is adapted to be disposed in an eXtension slot 18 leading from each of the openings 13. When the blade members are disposed in the extension slots 18 in their eXtreme limit of movement outwardly of the barrel, they are held securely in place. It will be noted that the blade members 14 cross each other, and the member 31 therein.

inner ends of the blade members are pivoted on a pin 19 secured to lugs 20 depending from a block 21. The inn'er end of each arm 14 is formed with a diagonal slot 22, the a1"- rangement being such that when the block 21 55 is moved downwardly the pin 19 engaging in the elongate diagonal slots 22, the blade members are fully forced outwardly through the openings 13, and in their final position rest in theeXtension slots 18.`

As shown in Fig. 3, the intermediate portion of the barrel 10 is flattened on opposite sides, the block. 21 conforming thereto in order to prevent rotative movements of the block 21 relative to the barrel but permitting 65 longitudinal movements thereof. Extending into the bloclr 21 and in screw threaded engagement therewith is a rod 23, which has bearing in a block 24 held in place by set screws 25. A collar 26 on the rod 23 engages 70 one side of the block 24 and a collar`27 pinned to the rod 23 is disposed on the opposite side of the bearing block 24. Thus it will be seen that the rod 23 is free to turn, but longitudinal movements thereof with'respect to the 75 barrel 10 are prevented. The outer end of the rod 23 is squared, as indicated Vat 28, for the reception of an actuating tool. Y

It will be apparent that rotation of therod 23 in one'direction imparts outward move8o ment to the block 21 for moving the blades 14Y outwardly through their openings, and movement of the'rod 23 in theopposite, direction causes the block 21' to move upwardly,

`thereby drawing the bladesj14 into the in- 85 terior of the barrel 10; Y l

` The upperend of the barrel 10 is enlarged, as indicated atg29, and disposed therein is a ring 30, whichis iixedfagainst movement and is formed to receive a substantially spherical Formed on the spherical member 31 is a pair of oppositely" disposed wings 32, which are adapted to engage lugs 33integral with the ring 30 and projecting inwardly therefrom. It will be lapparent that rotative movement of the member 31 in one direction or another will move the wings 32 into engagement kwith lugs 33, and thereby impart rotative movements to the anchor post for screwing it into o r out of the ground. Arlo0 rod 34 secured to the member 31 eXtends outside of the barrel, and is provided at its outer end with an eye 35 to receive a suitable tool, such as a bar, for turning the member 31 in one direction or the other.

Disposed directly beneath the ring 30 is a plate 36 provided with central opening 37 oi sutlicient size to permit the spherical member 31 to pass therethrough, but smaller than the member 31'V plus the Vwings 32. Also Aend or the member 31 is adapted to iit over the square end 28 of the rod 23. As shown bythe dotted lines of Fig. 1, the member 31 may bemoved into engagement with the outer end of the rod 23, and by'imparting a turning force to the rod 34, the rodi23-may be moved in one direction or the other to advance or retract the blade members 14. Itv will thus be seen that the member 31 may be used either to screw or unscrewthe post in the ground, and also to actuate the blade members 14. It will also be apparent that a cable may be attached tothe eye 35 on the outer end of the `rod 34.

rlhe above described anchor post may be manufactured at a comparatively low cost owing to the relatively small number of parts and the convenience in the assembly. Due to the fact that a single member is provided for both forcing the barrel into the ground and actuating the blade element, no additional tools are required for operating. i

It is to be understood that numerous changes in details of construction, arrange ment and operation maybe eected without departing from the spirit of the invention, especially as defined in the appended claims.

What I claimV as new and desire to secure by Letters Patent is: Y

1. An anchor post comprising an elongate barrel having a pointed lower end, and opposed openings adjacent such end, blades adapted to be projected through said openings, a pivotal mounting for said blades reciprocablelongitudinally in said barrel, a rod kin screw threaded engagement with said mounting, means to hold said rod from longitudinal movements, a combined rod and bar- 4 rel actuator for imparting turning movements to said barrel when in one position, and for imparting turning movements to said rod when in another position, and an extension for said actuator projecting outside the` barn rel and providing a cable-attaching means.

2. An anchor post comprising an elongate barrel having a pointedlower end and opbeneathsaid actuator and having an openposed openings adjacent thereto, blades i said barrel in one direction or the other, said member being engageable with the outer end of said rod for turning the, same in one direc'tion or the other, and means extending outside o'f the barrel for actuating said member.

3. An anchor post comprising an elongate barrel having a pairof oppositely disposed openings, blades projectable through said openings, means for actuating said bladesincluding a rotatable rod, a combined ro'd'and barrel actuator'or selectively turning said barrel or said rod, and means extending outside of'said barrel for actuating said last mentioned means.' j

4. An anchor post comprisingan elongate barrel having'a pair of opposed flattened .sides and a pairof oppositely disposed openings adjacent the lower end thereof,- blade members projectable through said openings, A, a moi'mting for said blade members recipro- J cable in said barrel, a rod in screw threaded engagement with said mounting, means to hold said rod against longitudinal'movement,

a member fixed to the outer end portion of said barrelhavingfa cavity, an actuator disposed in said cavity. having a pair of wings, lugs on the inside of said member engageable by Vsaid wings for imparting turning movementsto said barrel, al plate disposed ing through which said 4actuator isv adapted to pass, said actuator having ak polygonal .socket engageable with the outer end'of said rod, thereby to impart rotative movements to said rod, and a rod extending outside'of the barreland fixed to said actuator.
