The present invention relates to anchors and is articularly concerned withthe provision of anchors for attachment to logs or other members usually termed dead men.

One of the objects of the present invention is the provision. of a dead man anchor which 1s quickly attached to logs'or other members which may be buried in the earth later desired to abandon the anchor.

and which permits thedriving of a guy rod attachedthereto into the earth when it is Another object of the invention is the provision of a dead man anchor including means for the distribution of the strain over an extended surface of the dead man and quick detachable'means for connecting a guy rod to said first mentioned means.

Another object of the invention is the provision of a dead man anchor comprising a strain distributing plate and a detachable L thrust collar which are easily removed and of a guy rod to the dead man assembled and which permit the attachment anchor without the necessity-of special tools. Y i r r Another object of the invention is the provision of simple andefiective means for securing an. ordinary guy rod having an enlarged end which maybe pointed or merely vention will appear, more fully from the folupset toa dead man through which the guy rod passes. v

Other objects and advantages. of myinlowing description and-from the accompanylng drawings inwhlch simllarcharacters of reference lndlcate s milar parts throughout I the several views.

,. Referring to thesingle sheet of drawings:

Referring to Figure 1, IOindicates in its entirety, a log, timber, metal body or other 'realtively fixed member which is usually perspectiveof the en- 1928. s rial No. 268,693.

termed a dead man. The dead man is usually buried in the earth and presents a relatively large surface for engaging the earth above itand increasing the holding power of any member which may be secured 5 thereto.

I desire it to be understood, however, that m invention may be used for attaching guy rods .to other members besides those buried in the earth, such as trees, poles, and the like, whenever such procedure may be desirable. Consequently, the term dead man is employed throughout'this specification and in the claims in the generic senseof including any relatively'fixed member to which it may be desirable toattach a guy rod.

The dead man 10 is attached to the guy rod 11 by means of a securing device indicated in its entirety at 12. The securing device 12 comprises a metal plate 13 of suflicient thickness andarea to distribute the strain transmitted to it by the guy rod over a considerable'portion of the dead man 10.

The plate 13 may be of any shape but is preferably provided with a central aperture 14 of sufi'icient size to pass'the head 15 of the guy rod 11. The aperture 14 is also formed with a pair of grooves 16 adapted to pass lugs 17 carried by a sectional thrust collar which is indicatedin itsentirety at 18 in Figure 4. 30 Theplate 18 is'also provided with apertures 19 adapted to receive screws or other fastening means for securing the plate on the dead man 10. The sectional thrust collar 18 may consist of a plurality of sections adapted to be assembled together to form a collar embracing the guy rod 11 and filling the aperture 14 of the plate. In the present instance, two semi-cylindrical sections 20 and 20 are provided, each having an axial groove 21'of sufficient size so that when the two sections are assembled an axial bore 22 is formed which embraces "the guy rod 11. The semicylindrical sections20 and 20 are each provided with a flange 23 extending at substantially right angles and adapted to engage the plate 13 to limit the movement of the thrust collar relative to said plate, and the outer surface of the flange 23 is preferably formed as shown in Figure 3 with a grooved surface 24 complementary to the inner edge of the head upon the guy rod 11. For convenience in casting, the grooves 21 in the thrust collar sections and 2O? may be larger than necessary to receive the guy rod 11, but may be provided with hearing portions 25 and 26 at each end of substantially semi-cylindrical form and adapted to fit about the guy rod 11.

Carried by the trust collar sections 20 and 20 are a pair of lugs 17 having their lower edges 27 sufficiently spaced from the flange 23 to receive the plate 13 between the lu s 17 and the flange 23. The lugs 17 may be of any be passed through the bore 14 of the plate 13,- when the lugs 17 register with the grooves 16,

after which the thrust collar may be rotated relative to said plate, the lugs 17 passing out of registry with the grooves 16 and engaging below the plate 13 to engage the collartherein;

' The assembly and operation of my anchordevice with the dead man is as follows: The dead man is providedwith a bore 28, preferably ofthe same size as the aperture 14 in the "plate 13. The guy rod 11 may then have its head 15 inserted through the bore 28 and the aperture 1 1 and the thrust collar 18' may be assembled upon 'the guy rod between the head. 15 and the plate 13, after which the thrust collar may be passed through the apertures 14 and rotated, as previously described, to retain the collar in assembled relation with the plate and dead man. The assembled structure of the thrust collar and plate may then be forced into the bore 28, the lugs 17 forming grooves in the bore in which they will be received to prevent the thrust collar from rotating. The plate may then-be secured to the dead manby screws passing through the holes in the plate and the plate should preferably be secured so that the grooves 16 do notregister with the lugs 17. The plate being secured against rotation by its screws, and the thrust collar being secured by frictional engagement of its lugs in the bore, these parts will then be held 1 against relative rotation and the thrust collar cannot be detached from the plate without first removing the plate from the dead man.

The foregoing structure is easily manufactured and assembled and the thrust collar 18 provides a means for transmitting the thrust from the head of the guy rod to the plate 13 which distributes the strain over a substantial area of the dead man."

While I have illustrated anddescribed a specific embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not 'wish to-be limited to the precise details of bore through the same with a strain distributing plate carried at one side of said member and having an aperture aligned with said bore, a guy rod having an enlargedhead adapted to pass said bore and aperture, and sectionalmeans adapted to be received by said bore for preventing withdrawal of said head. 7
