ANCHOR-ROD.

Specification of Letters Patent.

Patented Aug. eaters.

Application filed June 4, 1917. Serial No. 172,739.

To all whom it may concern:

Be it known that l[, WILLIAM R. BRASHEAR, citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Anchor-Rods, of which the following is a specification.

My invention -relates to land anchors and more particularly to guy or strut anchors for telephone and telegraph poles, fence posts, bridge anchors and other analogous devices employing a buried support. The invention relates more especially to a detachable anchor rod particularly applicable to temporary structuresas for instance, tem porary telephone and telegraph lines, fences and derricks or elevator supports.

The object of the invention is to simplify the structure as well as the means and mode of operation of land anchors whereby they will not only be cheapened in construction, but will be more eficient in use, positive in operation, easily and quickly attached and detached, and unlikely to get out of repair.

A further object. of the invention is to provide an improved form of anchor rod engaging member from which the rod may be readily and quickly disengaged without 13%8 necessity of digging up the buried anc or.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof and the mode of operation or their equivalents, as hereinafter described and set forth in the claims.

Referring to the drawings, Figure 1 is a sectional side elevation of the assembled land anchor forming the subject matter hereof, in operative position. v Fig. 2 is a detail side elevation, partly in section, of the anchor rod and the engagement plate, showing in dotted lines the relative movement of the rod to efi'ect the release of same from the plate. Fig. 3 is a detail perspective view of the engagement plate. Fig. 4 is a fur ther modification.

Like parts are indicated by similar characters of reference throughout the several views. I

It is the present practice in telephone and telegraph construction, as well as in the erection of derricks and like constructions to employ as a land anchor to which the ends of the guys or strut cables are connected, anchor rods having at their upper ends eyes or loops through which the guys or struts are engaged and screw threaded at their lower ends. These anchor rods are extended through suitable holes in a log or large block of wood and are provided upon the protruding screw threaded end with a washer or collar and lock nuts. The expense of setting or burying such a land anchor is usually greater than the expense of the anchor rods themselves. The anchor rods themselves, however, are sufliciently valuable to warrant the recovery or salvaging of such rods if it can be efi'ected without the necessity of digging the anchor up or unearthing it.

To enable the recovery of the anchor rod with minimum labor and expense, with a loss only of the engagement plate and the wood block known as the dead man, is one of the primary objects of the present invention.

Referring to the drawing, 1 is the anchor rod having at its upper end the eye or loop 2 through which is engaged the guy or strut cable 8. The rod 1 extends through a transverse hole 4 in alog or block of wood 5 technically known as the dead man. The rod. 1 is preferably provided with a medial enlargement 6 substantially equal in diameter to the hole 4 in the dead man. At its lower end this enlarged medial portion 6 is provided with a tapered or conical extension 7 terminating in a shouldered conical head 8. The diameter of the head 8 is slightly less than that of the enlarged medial portion 6. Although the enlarged portion 6 is shown in the drawing somewhat extended and is the preferable form, this enlargement may be of comparatively short extent consisting substantially of only the tapered portion 7 as indicated at 'FFig. 4.

with the head 8, the jaws may be slightly recessed as at 11 on their adjacent ends. These notches or indentations in the ends of the jaws, however, are not essential. The engagement plate 9 is of comparatively heavy material suitably proportioned to the strain to which the anchor rod is to be subjected. The engagement plate is preferably of wrought iron, malleable iron or steel, although it may be of other material. It is not desirable that it should possess a great degree of elasticity or spring, although the normal degree of elasticity of such metals not objectionable. The head 8 of the anchor rod having been passed through the engagement plate, intermediate'the jaws 10, the latter are bent into close engagement with the neck 12 of the'anchor rod, beneath the shouldered head 8. This is best done by striking the jaws or tongues 10 with a hammer or a sledge. It will be understood that the anchor rod is extended through the dead man and engaged with the engagement plate before the parts are buried. The parts are then deeply and permanently buried.

When it is desired to disengage and remove the anchor rod 1, the guy or strut cable 3 is disengaged and the anchor rod 1 driven longitudinally downward by sledge hammer blows upon the upper exposed end. The longitudinal movement of the anchor rod 1 under the influence of such hammer blows forces the tapered or conical portion 7 of the rod between the jaws 10 of the engagement plate, thereby forcing said jaws open as indicated by dotted lines in Fig. 2. The tapered head 8 enables the rod to penetratemore easily togreater depth during the initial downwa'rd movement of the anchor rod. The upper or largest diameter of the taper 7 being. greater than the diameter of the head 8 forces the jaws 10 apart such distance that .upon the reversal of the direction of the anchor rod 1, the

' head 8 may readily pass between said jaws and be drawn through the hole 4 in the dead man 5 and from-the earth. The withdrawal of the, anchor rod may be effected in any suitable manner or by any means. However, a convenient and efi'ective means is provided by a block and tackle connected at one end to the eye 2 and at its opposite end to any suitable support or abutment.

While as before stated, the-enlargement of the anchor rod 1 may not necessarily ex- .tend beyond the tapered portion 7, the extended enlargement 6 is for the purpose of excluding dirt or gravel from-the hole 4 in the dead man, which might by becomin packed or locked therein interfere with the withdrawal of the anchor rod;

By 'the construction heretofore described,

it will be understood that theanchorrod 1,

may be readily removed by first-forcing it downward to separate the engagement jaws 10 sufliciently to permit the shouldered head 8 to pass between the jaws, and thenwithdead man 5 and the anchor plate 9 buried in the ground.

From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated a desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrange ment of parts, without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to certain structural features, 'it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention intoefiect, and the invention is therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.

Having thus described. my invention, I claim 1. In a land anchor, an anchor rod having anintegral terminal head, a longitudinally disposed cam surface adjacent to the head, an engagement plate having jaws adapted to engage said rod adjacent to the head, the cam surface upon said rod being brought into engagement with the jaws to forcesaid jaws apart a distance greater than the width of the head by a longitudinal movement of the rod whereby the rodhead may be disen gaged from said jaws.

2. In a land anchor, an anchor rod, a detent member normally limiting the reciprocatory movement of the rod in one direction,

and means for disengaging the rod from ing position by the engagement of said tapered portion upon a longitudinal movement of the rod.

4. In a land anchor, an anchor rod having a shoulder formed thereon, an inclined face g upon said rod extending laterally beyond the limit of said shoulder, and a detent memupon a longitudinal movement of the rod.

5. In a. land anchor,.an anchor rod, a detent plate having a flexible engagement 'ber adapted to be engaged with the shoulder but movable therefrom by said inclined face tongue normally engaging with said rod,

and means for flexing said tongue out of engaging position by a longitudinal movement of the rod.

6. In a land anchor, an anchor rod, a detent plate having oppositely disposed engagement tongues adapted to engage with said rod to limit its longitudinal movement in one direction, and means for simultaneously flexing said tongues out of engaging positions by a longitudinal movement of the rod in the opposite direction.

7. In a land anchor, an anchor rod, a detent plate having therein two substantially parallel spaced incisions connected medially by a transverse incision to form two oppositely disposed tongues between which the rod is extended, said tongues being adapted to normally prevent the Withdrawal of the rod, and means for disengaging said tongues from the rod by initially forcing the rod an additional distance through said detent plate, thereby permitting the withdrawal of the rod.

In testimony whereof I have hereunto set my hand this 24th day of May, A. D. 1917.

WILLIAM R. BRASHEAR.
