DAVID I-I. QUINN, OF BOSTON, MASSACHUSETTS, .AND WILLIAM E. SWIFT, QF LAKE FOREST, ILLINOIS.

Application led July 3,

To all whom t may concern.' i

Be it known that we, DAviD I-I. QUINN and vWILLIAM E. Swrrr, citizens of the United States of America, and residents of Boston, Massachusetts, and Lake Forest, Illinois, respectively, have invented a new and useful Improvement in Ground-Anchor Means, of which the following is a specification.

This invention relates to ground anchors for guy cables and the like.

The main objects of this invention are to provide a ground anchor including improved means for guiding the anchor posts so that they will enter the ground at the desired angle when they are being driven into anchoring position; to provide improved means for securing the posts together; and to provide improved fastening means for securing the guy cable to the anchor.

An illustrative embodiment of this inven tion is shown in the accompanying drawings wherein- Fig. 1 is a top plan of a ground anchor embodying this invention, part of the anchor posts being broken away.

Fig. 2 is a side elevation of the same.

Fig. 3 is a central vertical section ofthe ground anchor. y

Fig. 4L is an end view taken from the left of Fig. 3.

Fig. 5 is an end view taken from the right of Fig. 3.

Fig. 6 is a side view, on an enlarged scale, of one form of clamping means for fasten ing the guy cable to the anchor.

Fig.A 7 is an elevation of one of the jaws of the clamping means shown in Fig. 6, the view being taken on the line 7-7 of Fig. 6.

Fig. 8 is Yan elevation of the other aw of the clamping means, taken on line 8-8 of Fig. 6.

Fig. 9 is a bottom end view ofthe clampingmeans shown in Fig. 6.

Fig. 10 is a top end view of theclamping means shown in Fig. 6.

Fig. 11 is a central vertical section of the ground anchor, partly broken away, and showing a modified form of clamping means.

Fig. 12 is an enlarged side elevation of the driving cap.

Fig. 13 is a bottom plan of the same.

In the form shown, the ground anchor includes a guide member adapted to be supported on the ground and a pair of posts GROUND-ANCHCB. MEANS.

adapted to be driven into the ground through guideways formed in the guide member. 'Ihe guide member includes a central brace part for rigidly connecting the posts, and a pair of detachable guide sections which are removable from the brace after the posts have been driven into anchoring position and secured to the brace part. The device also includes an improved form of clamp for securing a guy cable to t-he posts. Referring to the drawings, the ground anchor includes a guide member 1 comprising separable parts coacting to form guideways for a pair of posts 2, arranged for attachment to part of the guide member, and to which a guy cable 3 may be secured by an improved form of clamp l. The device also includes a driving cap 5 constructed to protect the head ends of the bars from injury during the driving thereof and serve as a gage for preventing further driving of the posts after they have been located in proper position for attachment to the brace part of Y the guide member.

In the form shown, the guide member 1 comprises a central brace part 6 and a pair of separable sections 7 adapted to be detachably secured to the brace part on respectively opposite sides thereof by suitable fastening means, such as a bolt 8 extending transversely through the guide member.

The brace part 6, as illustrated, comprises a central web 9, and laterally extending ilanges 10, arranged to form a pair of downwardly diverging guide ways 11 of triangular cross section for receiving the posts 2.

The sections 7 are of substantially identical construct-ion and are in the form of plates having recesses 12 in their opposed faces for receiving the edges of the flanges 10. Formed in the plates 7 adjacent the recesses 12, Vare recesses 13 arranged to provide extensions of the guidewaysil. The ends of the plates 7 project inwardly to form shoulders 14 for confining the draft bars 2 within the guideways 11.

The posts 2 are shown in the form of angle bars having their lower ends pointed, as shown at 16. In the posts, adjacent the upper ends thereof, are apertures 17 arranged to register with an aperture18 formed in the central brace part 6, for receiving a` locking bolt 19, which rigidly secures the posts to the brace part after the former have been driven Vinto anchoring position.

The driving cap 5, as shown in Figs. 12 and 13, is in the form of ablock, having a striking face 20 and an inclined lower face 21, provided with a. pair of recesses 22 arranged at right angles to each other, forl receiving the upper edges of the posts. The

inner surfaces of the recesses 22 are sub-V Vpart 6. The driving cap 5 thus serves as a gage indicating the extent to which the posts should be driven in order to permit the insertion of the locking bolt 19.

y ,A preferred form of clamping means 4, as shown in Figs. 1, 3, 5, and 6, comprises a pair of

jaws

23 and 24 having centrally located

apertures

25 and 26, respectively, for receiving the locking bolt 19. The jaw 23 is provided with a bearing surface 27 of triangular cross section to conform to theV cross section of the angle bar posts 2. and the jaw 24 is provided with a. boss 28 forming a bearing surface for a. nut 29 carried by the bolt 19. The opposed facesof the

jaws

23 and 24 are recessed, as shown in Figs. 7 andS, to provide a substantially7 U shaped seat 30 lfor the guy cable 3. Formed on the jaw 23,` atV the base of the seat 30, is

y a knob 31 forming a cleat around which the guy cable is looped. The locking bolt 19 is also pro-vided with a bearing block 32 arranged between the head of the bolt and the adjacenty angle bar, as shown in Figs. 3 and 112 In operation, the brace part 6 and guide sections 7 are temporarily bolted together by means of the bolt 8 and placed upon the ground in the position shown in Figs. 1 and 2.A The posts 2 are then separately driven into the ground through the guideways 11, with the driving cap 5 loosely supported on the upper end of the post. When the post Y has been driven downwardly sufficiently to locate the aperture 17 in register with the aperture 18, the driving cap 5 rests upon the upper surface of the bearing member 1 to prevent further driving of the post. When both posts have been driven into anchoring position, the locking bolt 19 is inserted through the brace 6, clamping device 4, and

posts 2 and after the guy cable has been inserted between the

jaws

23 and 24, the nut- 29 is tightened to secure the posts 2 and brace part 6 together. lThe bolt 8 is then withdrawn to permit the side plates 7 to be removed from the device for use in laying other anchorso f The modified form of clamping means shown in Fig. 11 compr ses a hook 33, which Ais apertured to receive the locking bolt 19,

and which is provided with a triangular bearing surface 34 for engagement with the angle bar.

This description and the drawing have been mainly directed to a specific embodiment of this invention, but it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
